[0001] This utility model relates to the field of auxiliary equipment technology for power construction, specifically a cable reel auxiliary rolling device. Background Technology

[0002] Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of power systems. The basic structure of a power cable consists of four parts: the conductor, the insulation layer, the shielding layer, and the protective layer. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. With the continuous development of urban transformation in my country, the demand for power cables is increasing. During the laying process, power cables require rotating and rolling cable reels for cable handling.

[0003] The prior art includes a mobile horizontal assisted cable reel frame with application number 201911102086.8. The frame includes a frame body, which includes two slide rails with grooves. The slide rails are equipped with a main pulley group for assisting the rotation of the cable reel. The present invention uses four bearing pulleys in each group to position and assist the rolling of the cable reel, which makes it easier to put the cable reel on the frame and safer and less labor-intensive when rolling. It also has the advantages of reducing the time for putting the cable reel on the frame and adjusting the level, making it easier to transport, occupying less space, and saving labor. However, the stability of the cable reel rolling and rotating on the upper part of the base frame is poor, and it does not have a braking function. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary rolling device for cable reels, which solves the problems of poor stability and lack of braking function in the existing technology of cable reels rolling and rotating on the upper part of the base frame.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable reel auxiliary rolling device, comprising a bottom support, wherein a plurality of first rollers are rotated in the upper part of a groove in the bottom support, and an arc-shaped rolling groove is formed on the upper side of the plurality of first rollers; a second roller is also mounted on the inner wall of the upper end of the groove, and a plurality of second rollers are arranged at equal intervals; and a braking mechanism is also provided on the inner wall of the groove.

[0006] Furthermore, the first roller is a metal roller, and the second roller is a rubber pulley.

[0007] Furthermore, guide supports are provided inside both ends of the bottom bracket, and transverse support rods are inserted into the guide supports inside the two bottom brackets.

[0008] Furthermore, a stabilizing support is provided at one end of the bottom bracket, and a guide groove is provided on the upper side of the stabilizing support.

[0009] Furthermore, the braking mechanism includes a brake pad that is slidably mounted via a transverse support, and one end of the transverse support slides through the side wall of the bottom support and is threadedly connected to a screw.

[0010] Furthermore, one end of the screw is vertically rotatably mounted on the side wall of the bottom bracket via a bearing, and one end of the transverse support is provided with a threaded hole that is threadedly connected to the screw, and one end of the screw is provided with a handle.

[0011] Furthermore, the brake pad is an arc-shaped pad, and the outer wall of the brake pad is provided with a frosted layer.

[0013] 1. This utility model has multiple first rollers rotating in the upper part of the groove in the bottom bracket, which facilitates the longitudinal rotation and rolling of the cable reel on the upper part of the multiple first rollers for cable winding and unwinding. At the same time, a second roller is also installed on the inner wall of the upper end of the groove, which can change the sliding friction between the lower part of the cable reel and the inner wall of the groove into rolling friction, thereby improving the smoothness and stability of the cable reel's rolling and rotating adjustment in the upper part of the bottom bracket.

[0014] 2. In addition, the upper side of the multiple first rollers of this utility model is formed with arc-shaped rolling grooves. The first rollers are metal rollers, which can provide rolling support for the lower part of the cable reel at multiple angles, thereby improving the stability of the cable reel in the upper part of the bottom support for rolling and rotating adjustment.

[0015] 3. The present invention includes a brake pad slidably mounted on a transverse support, with one end of the transverse support sliding through the side wall of the bottom support and threadedly connected to a screw. One end of the screw is vertically rotatably mounted on the side wall of the bottom support via a bearing. One end of the transverse support is provided with a threaded hole threadedly connected to the screw. This allows the brake pad to be pressed against the lower outer wall of the cable reel by rotating the screw, thus enabling braking of the outer wall of the cable reel. The braking structure has high stability. Attached Figure Description
