Detailed Description
The invention discloses a method for manufacturing a pear-shaped head of a steel wire rope, which comprises the following steps as shown in figure 1:
the first step is as follows: construction preparation, cutting the steel wire rope to a required length;
the second step is that: the steel wire rope is inserted into the pear-shaped head along the positive direction;
the third step: placing the pear-shaped head into a clamping groove in a tensioning device, connecting the end part of the steel wire rope with a driving part in the tensioning device, starting the driving part to pull the steel wire rope, and pulling the steel wire rope reversely until the steel wire rope is tensioned;
the fourth step: and taking out the pear-shaped head to complete the positioning and tensioning of the steel wire rope and the pear-shaped head.
According to the invention, the pear-shaped head is fixed in the clamping groove at one end of the tensioning device, and the steel wire rope is tensioned by the driving part at the other end of the tensioning device, so that the steel wire rope is reversely bent and tensioned and positioned with the pear-shaped head, and the problems that the pear-shaped head is low in manufacturing efficiency, and the steel wire rope is easily deflected, slipped, emptied and damaged in the process of knocking the pear-shaped head by a sledge hammer in the prior art are solved.
In order to better realize the third step, specifically, as shown in fig. 2 to 3, in the tensioning device 100, the clamping groove 1 and the driving part 2 are located at opposite ends of the tensioning device 100, the tensioning device 100 includes a supporting frame 3, the clamping groove 1 is located on an upper surface of the supporting frame 3, as shown in fig. 2, the driving part 2 is arranged in the supporting frame 3, as shown in fig. 3, the driving part 3 is an electric block, the electric block is fixedly connected with an end of the steel wire rope through a locking chain, in the tensioning process, the pear-shaped head is placed in the clamping groove of the tensioning device, the end of the steel wire rope placed in the pear-shaped head is scattered, the other end of the steel wire rope is connected with the driving part of the tensioning device, the driving part is started to pull the steel wire rope, and the steel wire rope is pulled reversely until.
