The process is too cumbersome and time-consuming. Summary of the invention

[0004] In view of this, the present invention provides an installation bracket for laying cables in power engineering, which uses a lever to push the movable part to move, shortens the interval between the movable roller and the fixed roller, and clamps the movable roller and the fixed roller on both sides of the cable respectively, thereby ensuring the firmness of the cable connection, and fixes the movable part by a limiting tooth piece to prevent the movable part from moving outward and resetting, thereby ensuring the stability of the movable roller state. When the cable needs to be replaced, it is only necessary to pull the limiting tooth piece upward, and the movable part moves outward and resets under the influence of the thrust of spring A, thereby separating the movable roller from the cable, and the cable can be removed from the bracket for inspection and replacement.

[0005] The present invention provides an installation bracket for laying cables in an electric power engineering project, specifically comprising: an assembly base; the assembly base is respectively connected to a main connecting part and a flexible buffer, and the top end of the flexible buffer is connected to the main connecting part; two fixed square columns are respectively provided on the upper and lower sides of the assembly base, and fixed rollers are installed outside the fixed square columns; the main connecting part is connected to a movable part, and the movable part is respectively connected to two movable rollers, and the two movable rollers are located at the upper and lower sides of the assembly base; the top of the main connecting part is connected to a limiting tooth part, and the bottom end of the limiting tooth part is in contact with the movable part, and the outside of the main connecting part is connected to a lever.

[0013] Beneficial Effects

[0014] Compared with the traditional cable installation bracket, the installation bracket for laying cables in the power engineering according to the embodiments of the present invention has the following advantages: when the two cables are located at the upper and lower sides of the main connecting part, the movable part drives the two movable rollers to move inward synchronously, thereby reducing the interval between the movable roller and the fixed roller, so that the movable roller and the fixed roller are respectively clamped on both sides of the cable. The cable is bent by the thrust of the movable roller, thereby increasing the contact area between the cable and the movable roller and the fixed roller, thereby ensuring the firmness of the cable connection.

[0015] In addition, through the setting of the lever, the lever is used to push the movable part to move, thereby increasing the clamping force applied by the movable roller to the cable. While the lever pushes the movable part to move, the contact point between the power arm of the lever and the movable part gradually approaches the rotation connection point between the lever and the main connecting part, making the movement of the movable part more labor-saving; and in conjunction with the setting of the limit tooth part and the spring B, when the movable roller is clamped on the outer wall of the cable, the bottom end of the limit tooth part is inserted into the tooth groove under the influence of the thrust of the spring B, and the movable part is fixed by the limit tooth part to prevent the movable part from moving outward and resetting, thereby ensuring the stability of the state of the movable roller.

[0016] In addition, through the setting of spring A, when the limiting tooth part is pulled upward, the bottom end of the limiting tooth part is separated from the tooth groove, and the movable part moves outward and resets under the thrust of spring A, so that the movable roller is separated from the cable, so that the staff can remove the cable from the bracket for inspection and replacement, making the subsequent inspection and replacement of the cable easier.

[0017] In addition, through the setting of the flexible buffer, when the cable is subjected to instantaneous downward pulling force, the main connecting part rotates downward under the influence of the pulling force to unload the force, and the flexible buffer applies a reverse thrust to the main connecting part to provide buffering protection for the cable, thereby preventing the cable from breaking due to excessive instantaneous pulling force and causing safety hazards.
