Description

Technical Field

[0001] The utility model relates to the technical field of contact networks, in particular to a load-bearing cable joint wire clamp fastening fixture. Background Art

[0002] The high-speed railway contact network and the locomotive pantograph are in contact for a long time and are in a state of stress and vibration, which makes it easy for the load-bearing cable to break. The load-bearing cable joint clamp can be used to quickly connect the load-bearing cables and restore normal operation. The more commonly used load-bearing cable joint clamp is the load-bearing cable cone sleeve joint clamp, which includes a clamp body, and conical wedges and sleeve bolts on both sides of the clamp body to form a threaded wedge sleeve, which can connect the load-bearing cables on both sides into one. After the left and right threaded wedge sleeves are tightened, the two ends are symmetrical, and there are specific construction requirements for the exposed length of the thread and the torque.

[0003] However, when using the load-bearing cable cone sleeve joint wire clamp to connect the load-bearing cable, an adjustable wrench is generally used for tightening, because the hexagonal size of the outer side of the threaded wedge sleeve is 38-40mm, and the hexagonal size of the wire clamp body is 52mm. The maximum opening of the 450mm adjustable wrench is 55mm, so three 450mm adjustable wrenches are needed to operate, respectively tightening the threaded wedge sleeves on both sides and the wire clamp body in the middle. The 450mm adjustable wrench is heavy, and the load-bearing cable connection is an aerial operation, which consumes a lot of physical strength of the operator. The opening of the adjustable wrench itself needs to be adjusted and is easy to slide. When tightening in the middle, it is necessary to tighten it once, change the position and repeat the tightening again. In addition, the opening of the middle wrench needs to be adjusted during the operation, and the operation efficiency is low. The problem of the wrench falling is also very likely to occur when changing positions continuously, affecting the safety of the operation.

[0004] Therefore, it is necessary to design a new fastening fixture to replace the operation of three adjustable wrenches and overcome the above-mentioned defects. Summary of the invention
