How to use U shaped wire rope cards 5

1. The arrangement of the steel clamp head: the correct arrangement method of the steel clamp head should be buckled on the working section of the wire rope according to Figure 1, and the U-shaped bolt should be buckled on the tail section of the wire rope, and the steel clamp head shall not be alternately arranged on the wire rope.

3. The distance of the steel clamp: the distance between the wire rope clamps A is equal to 6-7 times the diameter of the wire rope.

4. The strength of the fixed place between the rope clamps: the strength of the fixed place of the clamp head is determined by the correct arrangement of the rope clamp on the wire rope, as well as the caution and proficiency of the rope clamp fixing and clamping. Improper tightening nuts or insufficient number of steel clamps can cause the rope end to slip at the beginning of the load.

If the rope clamps are arranged and clamped correctly in strict accordance with the recommended number, and all the rope clamps are placed on the longer part of the wire rope, and the U-shaped screw is placed on the shorter part or tail section of the wire, then the strength of the fixing place is 80% of the strength of the wire itself. The rope clamp is in practical use and is loaded.

After one or two times, the inspection should be carried out, and the rope clamp farthest from the collar should not be tightened separately first. The clamping rope (the first rope end) closest to the collar should be as close to the ring as possible, but it is still necessary to ensure that the rope clamp is properly tightened and the outer steel wire of the wire rope must not be damaged.

The rope clamps of commonly used wire ropes are divided into three types: U-type, horse-riding type, and holding type. Among them, the riding rope clamp has the strongest connection force and is the most widely used.

Generally, the type, type and quantity of rope clamps should be reasonably selected according to the diameter of the wire rope. Attention should be paid when using it:

1.When the rope clamp is selected, the net distance of the inner side of the U-ring should be about 1 3mm larger than the diameter of the wire rope.

2.The bolt of the buckle must be tightened, generally subject to the diameter of the wire rope being flattened;

3.The U-shaped part should be in contact with the wire rope end and should not be reversed with the main rope; The installation of rope clamps should be arranged in a smooth and equidistant manner;

4.In order to facilitate checking whether the rope clamp joint is safe and reliable or to find out whether the wire rope joint is slipping in time, a rope clamp is generally added at about 500mm behind the last rope clamp, and the wire rope head is released with a "safety bend"; If the wire rope joint slides, the phenomenon of the "safety bend" being straightened can be intuitively displayed, and treatment measures should be taken in time.

Card (QIA) ?Just press the two strands of rope and clamp them tightly with nuts and nuts.

The installation specifications of the wire rope rope clamp are as follows:

1. If the diameter of the rope card is more than 19 mm, it needs to be equipped with four or more card code buckles.

2. The connection strength of the selected rope buckle shall not be less than 85% of the rope breaking tensile force.

3. The spacing between the buckle and the buckle should not be less than six times the diameter of the wire rope.

4. The U-ring needs to be stuck at the end of the rope, and the pressing plate needs to hold down the main rope. The rope buckle must be installed on the side of the long end of the wire rope.

5. According to the GB5976-86 standard, the number of rope cards is generally not less than 3-5, the spacing of the rope cards should be 6-7 times the diameter of the wire rope, and the number of clips is determined according to the diameter of the wire rope, at least 3 for 19mn, at least 4 for 19--32mm, at least 5 for 32-38mm, at least 6 for 38-44mm, and at least 7 for 44-60mm.

Attention should be paid to the use of wire rope rope clamps

1. When using wire ropes, U-shaped bolts should be fixed. The degree of tightening needs to be up to one-third of the flattening of the wire rope. Because the wire rope is easy to deform after being stressed, when the wire rope is under stress, the rope clamp needs to be tightened to ensure that it is firm enough.

2. Once the wire rope is sliding, the rope card should be installed in a suitable position in time to fix the wire rope. Under normal circumstances, the safety rope clamp should be about 50 cm away from the last rope clamp.

3. The assembly of the rope card should be installed according to the requirements, and the spacing should be controlled at about 6-8 times the diameter of the wire rope when arranged, so that it can be arranged according to a sequence. Clamp the end of the rope with a U-ring first, and then place it on one side of the main rope with a pressure plate.

4. The selected clip specification should be determined according to the diameter of the wire rope, because the net distance inside the U-ring is larger, about 1-3 mm larger than the diameter of the rope. If the distance is too large, it is easy to get stuck in the wire rope in the later stage of the stove, so special attention should be paid.

When using the wire rope buckle, the U-shaped bolt should be tightened until the wire rope is flattened about 1 3. Due to the deformation of the wire rope after being stressed, the rope should be tightened for the second time after the wire rope is stressed to ensure the firmness of the joint.

Users who have used wire ropes know that the diameter of the wire rope will decrease after wear, and the wire is easy to break after the wire rope rusts. The diameter reduction rate and broken wire are the main basis for determining the scrapping of wire ropes.

Patented technology production of phosphate coated wire rope, phosphate film 3-60 grams of square meters, preferential use of manganese or zinc manganese phosphating, compared with the smooth wire rope production process, only to increase the final wire wear-resistant phosphating treatment process, rope wire wear resistance and corrosion resistance greatly improved, the use of phosphating after the wire without cold drawing directly twisted wire rope.

Wire rope U-shaped rope clamp is a common tool for fixing wire rope, and it is usually used in fields such as cargo transportation and construction engineering. The correct use of the U-shaped rope clamp can ensure that the wire rope is fixed and firm, so as to avoid accidents. The following will introduce how to use the wire rope U-rope clamp correctly.

First, place the U-shaped rope clamp on top of the wire rope, making sure that the rope is securely inserted into the U-groove of the rope clamp. Next, tighten the screws with a wrench until the rope clamp is tightly attached to the wire rope. It is important to make sure that the screws are tightened and not loosened to ensure that the rope clamp is securely attached to the wire rope.

Another important factor in the proper installation of wire rope crests is to use the correct size crests. The way to determine the correct U-shaped rope clamp size is to compare the rope thickness to the rope clamp size to make sure they match. If the U-shaped rope clamp is too small, it cannot guarantee the firmness of the wire rope; If it's too big, it's not only a waste of money, but it's also easy to lead to accidents.

In addition, it is also necessary to pay attention to the number of U-shaped rope clamps and the installation location. For wire ropes that require stronger fixations, a sufficient number of U-rope clamps need to be used. And it is necessary to choose the appropriate position to install the U-rope clamp to ensure that the fixing points are evenly distributed.

In short, the correct use of wire rope U-shape and random rope clamp can ensure the safety and stability of the wire rope. Make sure to select and use the correct U-rope clamp size, select the appropriate mounting location, and use the appropriate amount of U-rope clamps. These measures will ensure safe and efficient work. <>

1.Preparation.

Before the wire rope is clamped, we need to make some preparations. First, determine the size and shape of the wire rope to be used, as well as the shape and size of the object that needs to be jammed. Secondly, clean the position of the calipers and clamping wire ropes to ensure that they are dust- and grease-free.

Finally, confirm the appropriate size of the caliper to be used.

2.Put the steel empty Zheng wire rope into the caliper.

Place one end of the wire rope into the inside of the caliper. Make sure the wire rope is not bent or damaged, and hold the caliper tightly so that the wire rope is fixed in the center of the belly.

3.Stuck objects.

Wrap the wire rope in the caliper around the object that needs to be stuck and put the tail of the wire rope back into the inside of the caliper. The object can be stuck with it, and the tightening force should be moderate to avoid loose calipers.

4.Check the tightness of the wire rope.

After the object is stuck, check the tightness of the wire rope, if it is loose, it needs to be re-clamped. The clamping degree of the wire rope must achieve the purpose of fixing the object.

5.Confirm security.

Clamping wire rope is a type of operation that requires close attention to safety. When hoisting, transporting and parking the wire rope, it is necessary to keep the working area safe. In addition, never touch the wire rope with your bare hands, as touching the wire rope can cause serious injury.

6.Precautions.

When clamping the wire rope, be sure to pay attention to the bending degree and bending radius of the wire rope. If the bending radius of the wire rope is too small, it will cause irreversible damage to the wire rope. In addition, in order to ensure tightening, the size of the caliper must be adapted to the wire rope, especially the opening width of the caliper, and never exceed the pressure resistance of the wire rope.

7.Conclusion.

The correct method of clamping wire rope is very important and can greatly affect the safety and efficiency of the work. Read the above steps carefully and follow the correct method to carry out the caliper of the wire rope, which can ensure the safety of the wire rope and the caliper.
