Description

Technical Field

[0001] The utility model relates to the technical field of cable laying and installation, in particular to a temporary wiring device. Background Art

[0002] When new power facilities are being built or power equipment is being repaired, when power lines are interrupted due to natural disasters or other emergencies, and at event sites, temporary construction sites, or other places where temporary power is needed, temporary wiring is usually required to provide power supply.

[0003] In the prior art, there is a patent with application number CN202322004332.4, which provides a temporary wire stringing device for power engineering construction, including a wire stringing assembly, which includes a bottom plate, a slide rail, a slide seat, a fixed plate, a screw rod, a motor, a lifting plate, a rotating rod, a rotating plate, a T-slot, a T-block, a connecting rod, a fixed block, a spring, a connecting frame and a clamping plate; the upper surface of the bottom plate is welded with a slide rail, and the inner side wall of the slide rail is slidably connected with a slide seat. By rotating the rotating rod clockwise, the rotating rod will drive the rotating plate to rotate clockwise, and the rotating plate pushes the connecting rod and the T-block to both sides, so that the spring is compressed, and the T-block drives the clamping plates away from each other. After placing the cable between the two clamping plates, the rotating rod is released, and the spring stretches to push the clamping plates closer to each other to clamp and fix the cable. The motor drives the screw rod to rotate, so that the slide seat can move up and down along the outer side wall of the screw rod, and then the lifting plate can be driven up and down, so that the cable can be supported at different heights.

[0004] However, the above patent still has the following deficiencies during use:

[0005] The wiring device provided by the above patent limits the cable by elastically supporting the clamping plates with springs. When the cable is affected by external factors such as wind and pulling, the distance between the two clamping plates is easily affected and changed under the action of the elastic support, which makes it easy for the cable to detach from between the two clamping plates, thus causing the problem of unstable support.

[0040] Among them, the limiting part includes a column 28 fixedly installed on the top surface of the slide 23, a baffle 25 is fixedly installed on the top of the column 28, a limiting wheel 27 is rotatably provided on the periphery of the column 28, and the top and bottom ends of the limiting wheel 27 are respectively fixedly connected to the baffle 25 and the slide 23, and a spring 26 is sleeved on the periphery of the column 28.

[0041] When the utility model is in use:
