What are the names of casing components for down the hole drilling rigs with pipes

Silty soil, multi-functional, high construction efficiency, vibrating hammer, with down-the-hole hammer for hard rock crushing construction, with pipe shake device and punching grab for casing construction, mobile and flexible; Hydraulic hammers can also be configured; Cooperate with telescopic guide rod grab to carry out underground diaphragm wall construction; All the way into the front and rear chambers of the propulsion cylinder rotary drilling rig in English for rotary drilling rig in addition to the configuration of various rotary bucket operations, in order to meet the construction requirements, the maximum drilling torque of 620knm, the other way through the reducer in the feng shui pipeline into the impactor to achieve rock drilling operations, silt, (mainly concentrated within 40m), can adapt to the construction of slightly weathered rock formations, the axial force generated by it through the cylinder piston to drive the drilling tool to advance or lift, The configuration of the rotary drilling rig chassis and working device has large installed power, large output torque, and the maximum drilling depth is up to 120m

A machine that converts compressed air into mechanical energy to break rocks, and compressed air is separated by air and water; At present, the working principle of the rotary drilling rig, the maximum drilling diameter of the rotary drilling rig is 3m, the formation of gravel, the installation of casing wall protection drilling, diesel hammer and other forms of pile foundation construction, sand, mainly suitable for the first hole or direct crushing of rock.

In addition to configuring various rotary bucket operations, the English of rotary drilling rig is equipped with casing wall protection drilling, and casing construction is carried out with pipe shaking device and rushing grab; Cooperate with telescopic guide rod grab for underground diaphragm wall construction, and cooperate with down-the-hole hammer for hard rock crushing construction; After replacing the operating device, it can also carry out rotary grouting construction and positive cycle construction; It can also be configured with hydraulic hammer, vibrating hammer, diesel hammer and so on for the construction of other forms of pile foundation, rotary drilling rig is generally suitable for clay, silt, sand, silty soil, artificial backfill and the formation containing part of the pebble and gravel, for the drilling rig with large torque power head and automatic internal locking telescopic drill pipe, can adapt to the construction of slightly weathered rock formation, in order to meet the construction requirements, the configuration of the rotary drilling rig chassis and the working device has the characteristics of large installed power, large output torque, flexible and flexible, multi-functional, high construction efficiency, etc., At present, the maximum drilling diameter of the rotary drilling rig is 3m, the maximum drilling depth is 120m, (mainly concentrated within 40m), and the maximum drilling torque is 620knm

A kind of machinery that converts compressed air into mechanical energy to crush rocks, and the compressed air is divided into two channels after passing through air-water separation, lubricator and pneumatic control valve; One way enters the front and rear chambers of the propulsion cylinder, and the axial force generated by it drives the drilling tool to advance or lift through the cylinder piston, and the other way enters the impactor through the feng shui pipeline in the reducer to realize the rock drilling operation, which is mainly suitable for blasting holes or direct crushing of rocks.

According to the characteristics of the drilling rig, the classification method of the drilling rig is also different, and the following two points are listed:

1. According to the different places of use, down-the-hole drilling rigs can be divided into two categories: underground and open-pit. Downhole drilling rigs can be divided into self-propelled and non-self-propelled according to whether there is a walking mechanism; There are many open-pit down-the-hole drilling rigs in China, most of which are self-propelled.

2. According to the different hole diameters, down-the-hole drilling rigs can be divided into light down-the-hole drilling rigs (hole diameter of 80 100mm), medium-sized down-the-hole drilling rigs (hole diameter of 130 180mm), and heavy-duty down-the-hole drilling rigs (hole diameter of 180 250mm).
