Description

Technical Field

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

[0002] Cable laying refers to the process of laying and installing cables along a road that has been explored to form a cable line. According to the application scenario, it can be divided into several laying methods, such as overhead, ground, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. According to the project requirements and design specifications, different laying methods and technologies can be used. In the process of laying cables, a cable traction device is usually required for cable laying.

[0003] In the prior art, since the cable is heavy, when laying the cable, the cable will be continuously accelerated when leaving the cable roller due to uncontrollable factors, which may cause damage to the roller or even breakage and injure people. The existing cable roller does not have an emergency brake function, and traditional cable laying adopts a rough method of directly dragging the cable, which can easily cause damage to the outer insulation skin and deteriorate the cable quality. Therefore, a cable laying traction device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cable laying traction device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top of the oil pump stretches out the side of the oil pump with a push-button to push the top of the oil pump into the oil pump pocket. The top of the oil pump stretches out the side of the oil pump pocket.

[0007] Preferably, the anti-wear component includes a fixing plate vertically arranged and fixedly connected to the top of the traction plate, one side of the fixing plate is rotatably connected to a horizontally arranged rotating shaft, the outer side of the rotating shaft is fixedly connected to a horizontally arranged supporting wheel, and the outer side of the supporting wheel is fixedly connected to a silicone pad.

[0008] Preferably, the number of the fixing plate, the rotating shaft, the supporting wheel and the silicone pad is two each.

[0009] Preferably, the number of the universal wheels is four, the universal wheels are evenly distributed at the bottom edge of the traction plate, and the number of the support rods is four.

[0010] Preferably, there are two oil pipes, the bottom end of the hydraulic oil pump is fixedly connected to the top end of the traction plate, the number of the auxiliary oil pipes, pistons, limit rods and brake pads are all ten, and the outer side of the piston fits tightly with the inner side of the auxiliary oil pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by setting the support rod, main oil pipe, oil delivery pipe, hydraulic oil pump, auxiliary oil pipe, piston, limit rod, brake pad, bearing and cable roller, the brake can be applied when the cable leaves the roller quickly, so as to reduce the speed of the cable movement and prevent the cable roller from being damaged or even broken due to the rapid rotation. The equipment is powered on before use. When the cable moves quickly due to uncontrollable factors, the bearing and the cable roller rotate quickly on the outside of the main oil pipe. At this time, the hydraulic oil pump is started, and the hydraulic oil pump pumps the hydraulic oil inside the hydraulic oil pump into the inside of the main oil pipe through the oil delivery pipe. The hydraulic oil inside the main oil pipe enters the inside of the auxiliary oil pipe and pushes the piston and the limit rod to slide inside the auxiliary oil pipe. The piston and the limit rod slide in the opposite direction of the main oil pipe, thereby pushing the brake pad to fit tightly with the inside of the cable roller, so that the rotation speed of the cable roller and the bearing is slowed down and finally stops rotating.

[0013] 2. In the utility model, by providing anti-wear components, fixed plates, rotating shafts, supporting wheels and silicone pads, it is possible to prevent the outer insulating skin from breaking due to friction between the outer layer and the traction plate or the ground during cable laying, thereby increasing the service life of the cable. When laying the cable, first pass the cable between the two supporting wheels, and then start laying. The cable roller and the bearing rotate on the outside of the main oil pipe, and the rotating shaft and the supporting wheel rotate on one side of the fixed plate. The cable can be laid normally, and the silicone pad located on the outside of the supporting wheel can further protect the cable and prevent it from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS
