How are laser screeds classified?

After nearly ten years of development, the technology of laser leveling machine has gradually matured, and there are more and more types and models of machines. According to the size of the model, it can be divided into two categories: large laser screed machine and small laser screed. According to the structure of the machine, it can be divided into:

Two-wheel laser leveling machine, four-wheel laser leveling machine, six-wheel laser leveling machine, telescopic arm laser leveling machine, 360-degree rotary telescopic arm laser leveling machine.

Small laser screed: mainly refers to the hand-held laser screed, which is divided into two types: four-wheel and two-wheel. The configuration is generally low, and ** is also relatively low.

It is mainly used for the construction of ordinary floors and floor-level cement floors. The body is light and compact, and it has a wide range of adaptation. Generally, the second wheel ** is low, without a auger, and two people are needed to assist in feeding.

The four wheels generally come with their own auger, which can assist in paving, and generally one person can assist in replenishment.

Large-scale laser leveling machine: mainly refers to six-wheel laser leveling machine and telescopic arm laser leveling machine. The configuration is generally higher, and the ** is also relatively high. It is suitable for complex terrain and projects with high construction requirements.

Laser levelers are used in many situations of ground construction projects, from the simplest floor paving to warehouses to high-rise buildings. Its working principle is mainly divided into the following aspects: 1. The principle of leveling

It is the use of very accurate laser control technology, closed-loop control technology and high-accuracy hydraulic system, and finally with the help of computer adjustment to control, which is very different from other general paving construction technology, is a unique feature of the leveling machine. 2. The principle of leveling: relying on the power generated by the machine to make the leveling head of the laser machine move, coupled with the guidance of the computer and the laser, it can automatically find the leveling, and then carry out the next work of leveling.

There is a scraper and an instrument capable of vibrating at the leveling head, which can complete most of the procedures in the project, and can pass at one time, and the computer can change the height standard ten times per second, and the number of vibrations per minute reaches about 4,000 times.

The characteristics are also divided into two aspects: 1. The laser used to mark the height is distributed in another place, so it will not be controlled by the template when the elevation is elevated, and there will be no error due to repeated use. 2. It can only control the horizontal slope or the vertical slope, and it is also completed by the four major systems of the leveler.

If the road topography that needs to be constructed is more complex, and there are still high requirements for drainage, you can use a three-dimensional special-shaped ground system to deal with this problem.

There are many laser leveling machine manufacturers, but to say which one is the best, you need to consider it according to many factors. First of all, laser leveling machine brands that focus on quality and performance tend to have a good reputation and popularity in the market. Secondly, consider the materials and technologies used in the production process, which are important factors that affect product quality and production efficiency.

Finally, support and service are also important factors, and an excellent laser screed manufacturer should provide perfect technical support and after-sales service.

When choosing a laser screed manufacturer, you need to find a company with a good reputation and innovative technology. Some well-known laser screed brands, such as Trumpf and Bystronic, usually offer high-quality laser screeds as well as worldwide technical support and after-sales service. In addition, some good options can also be learned by looking at relevant customer feedback and product reviews.

In terms of service and support, Trumpf has established a strong service network worldwide and can provide customers with customized training courses to help them better use their equipment.

In short, when choosing a laser leveling machine manufacturer, many factors need to be carefully considered, including product roundness, production technology, service support, etc. It is very important to choose a reliable manufacturer that provides comprehensive support and service to customers. <>

(1) The leveling principle of the laser leveling machine is realized under the automatic control of the computer by using precision laser technology, closed-loop control technology and highly precise hydraulic system, which is the most prominent feature that distinguishes it from other floor construction technology.

2) The leveling principle of the precision laser leveling machine is to rely on the leveling head driven by hydraulic force, cooperate with the laser system and computer control system to complete the leveling work at the same time as automatic leveling. The leveling head is equipped with an integrated design scraper, vibrator and whole plate, which integrates all leveling, leveling, vibrating and compaction work in one and completes it at one time. The computer control system automatically adjusts the elevation in real time 10 times per second, and the vibration frequency of the vibrator with balanced design reaches 3000 minutes.

3) The laser emitters used to control the ground elevation are arranged independently, so that the floor elevation is not controlled by the template and does not produce cumulative errors.

4) The laser leveling machine can also automatically control the longitudinal and transverse slopes, which is also completed by the laser system, computer system, hydraulic system and mechanical system. For complex shapes of the ground with high requirements for drainage, a three-dimensional special-shaped ground treatment system can also be selected.

The grader deal mentions that the land leveling system consists of: a laser transmitter, a laser receiver, an electric telescopic rod (or manual mast), a controller and an electrical hydraulic component, and a grader shovel.

The laser emitter emits an extremely thin laser beam that rotates 360° to form a datum over the construction site. After receiving the laser signal, the laser receiver installed on the grading shovel continuously sends the elevation signal to the controller, and after the controller calculates and processes, the correction signal is transmitted to the hydraulic control valve, and the oil cylinder on the grading shovel is controlled by the hydraulic system, and then the leveling shovel blade is controlled to achieve the purpose of leveling the land.

Suitable working environment for laser leveling system:

Wasteland recultivation, old land renovation, new field leveling, slope land to terrace, paddy field leveling, and dry land leveling.

Benefits and benefits of laser leveling of farmland:

Water-saving - laser leveling technology can make the ground flatness reach a positive and negative error of 2cm, which can generally save more than 30% of water, and can save 100 cubic meters of water per mu, so as to achieve the purpose of water conservation.

Land saving - the use of laser technology to accurately level the land, with the corresponding measures, can reduce the area of the ridge by 3%-5%, so that the land can be fully utilized.

Fertilizer saving - due to the improvement of land flatness, the distribution of chemical fertilizer is uniform, the loss of chemical fertilizer and the phenomenon of fertilizer removal are reduced, and the utilization rate of chemical fertilizer is increased by 20%, which ensures the emergence rate of crops.

Yield increase - 20%-30% per mu can be increased, which not only increases yield, but also improves the quality of crops.

Cost reduction – The implementation of this technology can reduce the production cost of crops (rice, wheat, soybeans, cotton and corn) while increasing yields and benefits.

The concrete leveling machine is guided by a laser and is a kind of mechanical equipment used for leveling and leveling concrete. The laser transmitter produces a rotating laser, and the laser receiver on the leveling machine receives the signal, which is analyzed by the laser measurement and control system, and its deviation will be fed back to the sensitive computer control system on the leveling machine, and the left and right electric push rods will adjust the height of the scraper to ensure the leveling accuracy. Paving, scraping, vibrating, leveling floor concrete, mainly paving the concrete to an elevation greater than the design requirements, vibrating and leveling the concrete.

The traditional method is: pier punching, bidding high, pay-off side mold, dump truck concrete, manual preliminary leveling, vibrator vibrating concrete, and then using a special double-row steel pipe vibration tamping and back and forth leveling. Sanren Machinery concrete laser leveling machine is to use a scraper to take away the high concrete and preliminarily scrape it to achieve the elevation required by the design.

Hydraulically driven vibrating motor produces vibration, the frequency is 4200 times, and the whole vibrating plate is driven to vibrate the concrete together. The leveling of the laser leveling machine does not need to be controlled by the pull line, nor does it need the side template to control the ground elevation, but is controlled by the laser measurement and control system on the leveling machine, as long as the laser emitter is not disturbed, no matter the leveling machine moves to the first, it can ensure that the overall elevation of the ground after paving is not affected.

Precision laser leveling machine is developed according to the increasing demand for ground quality such as strength, flatness, levelness and so on in modern industrial plants, large shopping malls, warehouses and other large-area cement concrete floors. The quality of the ground paved with precision laser leveling machine is much better than that of the ground paved by conventional methods - the flatness and levelness of the ground are increased by more than 3 times, and the compactness and strength are increased by more than 20%. At the same time, it can also improve the ergonomics by more than 50% and save about 35% of the labor.

In addition, it can be easily laid with high-strength concrete, low-slump concrete and fibrous concrete. The laser system is equipped with a variety of automatic control elements, which monitors the elevation of the leveling head in real time at a frequency of 10 times per second, ensuring that the flatness and levelness of the floor are effectively controlled. At the same time, its powerful vibrator vibrates at a frequency of 3000 minutes to ensure that the concrete vibrates compactly, so that the whole paved concrete matrix is homogeneous and dense.
