Description

Clamp for tensioning steel wire rope

Technical Field

The utility model relates to an anchor clamps for wire rope tensioning belongs to metallurgical industry hoisting equipment technical field.

Background

The steel wire rope plays a vital role in industrial production, such as lifting of an elevator, lifting of an inclined shaft, a bucket and the like, in practical application, a part of the steel wire rope needs to provide initial pretightening force for the steel wire rope before use, the steel wire rope needs to be fixed in the steel wire rope tensioning process, and the steel wire rope is not easy to fix due to the fact that the surface of the steel wire rope is smooth and grease adheres to the steel wire rope, and the tensioning of the steel wire rope is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anchor clamps for wire rope tensioning, simple structure can be fixed firm with wire rope, for wire rope's tensioning improves reliable guarantee, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

a clamp for tensioning a steel wire rope comprises an upper buckle, a lower buckle, a bolt hole and a hoisting hole, wherein the section of the upper buckle is in a semicircular shape matched with the steel wire rope, and the outer edges of the upper buckle extending outwards are arranged at the two ends of the semicircular shape along the radial direction; the lower buckle is rectangular, a semicircular groove matched with the steel wire rope is formed in the upper surface of the rectangle, the outer edges of the lower buckle extending outwards are formed in the two side surfaces of the rectangle, a hoisting plate is arranged in the front of the rectangle, and hoisting holes are formed in the hoisting plate; the upper buckle outer edge and the lower buckle outer edge are respectively provided with a bolt hole, and the upper buckle and the lower buckle are connected through a bolt to form a clamp for tensioning the steel wire rope.

Nicks are arranged on the inner surface of the upper buckle and the semicircular groove of the lower buckle.

The inner surface of the upper buckle and the nicks on the semicircular groove of the lower buckle are in a cross shape.

The utility model has the advantages that: simple structure, the operation of being convenient for can be fixed firm with wire rope, improves reliable guarantee for wire rope's tensioning.

in the figure: go up buckle 1, lower buckle 2, bolt hole 3, wire rope 4, hole for hoist 5, go up buckle outer edge 6, semicircular groove 7, buckle outer edge 8 down.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to the attached drawings 1-3, the clamp for tensioning the steel wire rope comprises an upper buckle 1, a lower buckle 2, a bolt hole 3 and a hoisting hole 5, wherein the section of the upper buckle 1 is in a semicircular shape matched with the steel wire rope, and outer edges 6 of the upper buckle, which extend outwards, are arranged at two ends of the semicircular shape along the radial direction; the lower buckle 2 is rectangular, a semicircular groove 7 matched with the steel wire rope is formed in the rectangular surface, the outer edges 8 of the lower buckle extending outwards are formed in the two side surfaces of the rectangular surface, a hoisting plate is arranged in front of the rectangular surface, and a hoisting hole 5 is formed in the hoisting plate; the upper buckle outer edge 6 and the lower buckle outer edge 8 are respectively provided with a bolt hole 3, and the upper buckle 1 and the lower buckle 2 are connected through a bolt to form a clamp for tensioning a steel wire rope.

In this embodiment, referring to fig. 1 to 3, in order to fix the wire rope more firmly, the inner surface of the semicircular upper clip 1 and the semicircular groove 7 of the lower clip 2, i.e., the surface contacting with the wire rope, are roughened, or cross-shaped scores are added to the inner surface of the upper clip 1 and the semicircular groove 7 of the lower clip 2 to increase the roughness thereof.

The specific working process is as follows:

(1) arranging a steel wire rope 4 between the upper buckle 1 and the lower buckle 2;

(2) the upper buckle 1 and the lower buckle 2 are connected together by a bolt;

(3) a rigging penetrates through the hoisting hole 5 of the lower buckle 2;

(4) pre-tightening force is applied to the steel wire rope 4 by a chain block or other pre-tightening devices;

(5) after the corresponding tension force value is reached, fixing the steel wire rope 4;

(6) removing the chain block or other pre-tightening devices;

(7) the clamp is dismantled.
