Therefore, a single/lug bush type, a double lug single/double screw type cable, and a double lug double screw type cable, which have excellent performance in structural performance, installation and maintenance, and the like, are widely used. Because structural strength test detection is a necessary link of the products in the processes of design, technical development and test, the requirement of the fork-ear cable structural strength test is gradually increased in recent years.

Due to the limitation of the testing machine, the anchorage device needs to be sequentially taken down from the cable body and installed in the installation process of the fork lug type cable. In the prior art, the method adopted by a laboratory is to fix two ends of a cable body through two bridge cranes, wherein one crane lifts an anchorage at one end of a cable to the central position in a cylinder with the diameter slightly larger than the diagonal length of a vertical plate, a wood plate is inserted between the anchorage and the inner wall of the cylinder to fasten the anchorage and the inclined wood, a hemp rope meeting the requirement is then threaded into a pin hole of the vertical plate, the outer end of the vertical plate is wound for a certain number of turns, the other end of the hemp rope is sleeved in a crane hook, and finally the hemp rope is lifted by the crane and screwed out of the anchorage. In the process, due to the influence of manual installation factors, the geometric sizes of the anchor and the cable body of the test object are not uniform, the hoisting height, the centering precision and the fastening degree of the anchor and the cable body cannot meet the requirements in the actual installation process, and therefore the installation efficiency and the installation power are low, and time and labor are wasted.
