U-shaped clip for steel wire rope

The steel wire rope clamp shall be used together. The U-shaped ring shall be clamped on one side of the rope head, and the pressing plate shall be placed on one side of the main rope.

1. The wire rope with a diameter greater than 19 mm shall have at least 4 clips; At least 5 pieces larger than 32mm; At least 6 pieces larger than 38mm; At least 7 more than 44mm. The clamping strength is greater than 80% of the rope breaking force. The distance between clips is more than 6 times the rope diameter. U-shaped rope clamp, press plate pressing main rope.

2. The size of the clip shall be consistent with the thickness of the steel wire rope. The inner clear distance of the U-shaped ring shall be 1~3 mm larger than the diameter of the steel wire rope. If the clear distance is too large, it is not easy to jam the rope and accidents may occur. When installing the clip, the screw must be tightened until the rope with a diameter of 1/3~1/4 is flattened. After the rope is stressed, the screw must be tightened again to ensure that the joint is firm and reliable.

3. According to the structural requirements, the nominal diameter of the wire rope shall not be less than 14 and the number of rope clamps shall not be less than 3. The distance between clamps is usually 6~7 times of the nominal diameter of the wire rope.

Extension: steel wire rope is a spiral harness twisted by steel wires with mechanical properties and geometric dimensions meeting the requirements according to certain rules. The steel wire rope is composed of steel wire, rope core and grease, and the steel wire material is carbon steel or alloy steel. The wire rope core is composed of natural fiber core, synthetic fiber core, asbestos core or soft metal. Asbestos core wire or flexible wire twisted metal core should be used for high temperature work.

Use of wire rope clamp

1、 It can be used on various engineering hoisting machinery, metallurgical and mining equipment, oil field derrick, port railway loading and unloading, forestry machinery, electrical equipment, aviation and maritime, land transportation, engineering rescue, salvage of sunken ships, lifting, hoisting and traction rigs of factories and mining enterprises.

2、 Product features: It has the same strength as steel wire rope, safe use, beautiful appearance, smooth transition, large safety load for hoisting operation, and can resist impact load, with long service life.

3、 Product quality: strictly implement the international standards and national standards of this technology in production, and carry out sampling inspection according to its requirements. The test pieces must reach the strength equivalent to the steel wire rope, that is, the broken and crimped parts of the steel wire rope will not slip, detach, or break

Wire rope buckle is also called rope clamp of wire rope. It is mainly used for temporary connection of steel wire rope, fixing of the rear hand rope when the steel wire rope passes through the pulley block, and fixing of the cable wind rope head on the climbing pole. The main varieties of steel wire rope include phosphating coating steel wire rope, galvanized steel wire rope, stainless steel wire rope, etc. It is a widely used wire rope clamp in hoisting operation. There are three types of wire rope clips commonly used: horse riding type, fist grip type and pressing plate type. Among them, the horse riding clip is the standard wire rope clip with the strongest connection force and is the most widely used. Second, press plate type. Fist grip type has no base, which is easy to damage the wire rope and has poor connection force. Therefore, it is only used in secondary places [1].

matters needing attention

Pay attention to the following items when using rope clips:

(1) The size of the clip shall be suitable for the thickness of the wire rope. The inner clear distance of the U-shaped ring shall be 1~3mm larger than the diameter of the wire rope. The clear distance is too large to clamp the rope.

(2) When using, tighten the U-shaped bolt until the wire rope is flattened by about 1/3. As the wire rope is deformed after being stressed, the rope clamp shall be tightened for the second time after being stressed to ensure the firm joint. If it is necessary to check whether the rope clip slides after the wire rope is stressed, an additional safety rope clip can be used. The safety rope clamp is installed about 500mm away from the last rope clamp, and the rope head is clamped with the main rope after a safety bend is released. In this way, if the clamp slips, the safety bend will be straightened, so that it can be found at any time and reinforced in time.

(3) The arrangement spacing between rope clips is generally about 6-8 times of the diameter of the steel wire rope. The rope clips should be arranged in order. The U-shaped ring should be clamped on one side of the rope head, and the pressing plate should be placed on one side of the main rope.

(4) Fixing method of wire rope end: generally, there are two kinds of single knot and double knot.
Single sleeve knot, also known as cross knot, is used at both ends of wire rope or for fixing ropes.
Double sleeve knot, also known as double cross knot and symmetrical knot, is used for both ends of wire rope and also for fixing rope ends.
Precautions for the use of wire rope clamp: it shall not be used for a long time or repeatedly
