Description

Technical Field

[0001] The utility model relates to the technical field of cable protection equipment, in particular to a cable protection device for electric power engineering. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. The transmission and distribution of electric energy is mainly achieved through high and low voltage AC power networks. During the construction of power engineering, it is necessary to lay power engineering cables in the pipelines below the cable well to achieve the transmission of electric energy.

[0003] Since the power engineering cable is usually affected by the outside world during operation and rubs against the inner wall of the cable well, the power engineering cable will be damaged over time. In order to protect the power engineering cable, the power engineering cable is pressed into the inside of the fixing clamp during the laying of the power engineering cable, and then the nail is passed through the fixing clamp to connect with the inner wall of the cable well, thereby realizing the limited fixation of the power engineering cable. The fixing clamp is usually a plastic part, and one side of the plastic part has an arc-shaped opening matching the size of the power engineering cable;

[0004] When the existing fixing clamp is in use, the shape of the arc-shaped mouth cannot match the power engineering cables of different diameters. If the arc-shaped mouth is too large, the power engineering cable will become loose, and if the arc-shaped mouth is too small, it will not be able to match and position. Some power engineering cable protection devices place the power engineering cable into the placement groove, and then rotate the limit plate to make the limit plate contact with the power engineering cable, thereby achieving the limit fixation of the power engineering cable. Although this method improves the protection effect of the power engineering cable, after adjusting the position of the limit plate, an additional self-locking component needs to be added, and the operation is relatively cumbersome. For this reason, we propose a power engineering cable protection device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a power engineering cable protection device. Through the coordinated setting of the screw and the rack plate, the position of the limit plate can be adjusted, so that the limit plate can limit and fix the power engineering cable. After the position of the limit plate is adjusted, it can be self-locked through the screw structure, which solves the problem of damage caused by friction between the power engineering cable and the inner wall of the cable well, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power engineering cable protection device, comprising a base and a limiting mechanism;

[0008] Limiting mechanism: It includes a connecting rod and a limiting plate. The connecting rod is rotatably connected to the lower side of the mounting seat through bearings. A limiting plate is arranged in the middle of the outer arc surface of the connecting rod. The position of the limiting plate can be adjusted through the cooperation of the screw rod and the rack plate, so that the limiting plate can limit and fix the power engineering cable. After the position of the limiting plate is adjusted, it can be self-locked through the screw rod structure, which solves the problem of damage caused by friction between the power engineering cable and the inner wall of the cable well.

[0009] Furthermore, the limiting mechanism also includes gears, and the gears are all arranged on the front side of the outer arc surface of the connecting rod. The two gears are meshed and connected to drive the limiting plate to rotate.

[0010] Furthermore, the limiting mechanism also includes an adjusting gear and a rack plate, the rack plate is slidably connected to the bottom wall of the mounting seat, the adjusting gear is arranged at the front end of the connecting rod on the left, the adjusting gear is meshingly connected to the rack plate, and the gears are all located on the rear side of the adjusting gear, which can drive the gear on the left to rotate.

[0011] Furthermore, the limiting mechanism also includes a screw rod, which is rotatably connected to the lower side of the mounting seat through a bearing, and the screw rod is threadedly connected to a threaded hole provided at the right end of the rack plate, so that the position of the rack plate can be adjusted.

[0012] Furthermore, the limiting mechanism also includes an adjusting knob, which is arranged at the right end of the screw rod and can drive the screw rod to rotate.

[0013] Furthermore, it also includes insulating rubber pads, which are respectively arranged in the middle of the inner arc surface of the limiting plate to prevent the limiting plate from causing damage to the power engineering cable.

[0014] Furthermore, it also includes mounting holes, which are respectively arranged at the four corners of the upper end of the base to support and fix the base and the upper equipment.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the power engineering cable protection device has the following advantages:

[0016] When working, put the power engineering cable into the placement groove, and then rotate the adjusting knob, which drives the screw to rotate. The screw drives the rack plate to move through the threaded connection during the rotation. The rack plate drives the adjusting gear to rotate through the meshing connection during the movement. The adjusting gear drives the gear on the left to rotate through the connecting rod on the left, and the gear on the left drives the gear on the right to rotate through the meshing connection, so that the connecting rod drives the limit plate to rotate toward the end close to the inner center of the base. At this time, the distance between the two limit plates gradually decreases, and then the limit plate passes through the installation groove and extends into the placement groove. Finally, the limit plate is limited and fixed to the power engineering cable through the insulating rubber pad. Through the coordinated setting of the screw and the rack plate, the position of the limit plate can be adjusted, so that the limit plate can limit and fix the power engineering cable. After the position of the limit plate is adjusted, it can be self-locked through the screw rod structure, which solves the problem of damage caused by friction between the power engineering cable and the inner wall of the cable well.
