Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing equipment, in particular to a fixing device for coal mine power supply cables. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. In order to facilitate the development of coal mining, it is usually necessary to power the electromechanical equipment used. The existing power supply methods are all carried out through power supply cables, and in order to ensure the normal operation of the power supply circuit, the cables need to be fixed.

[0003] A fixing device for coal mine power supply cables with a publication number of CN217215734U has been retrieved. The fixing device for coal mine power supply cables includes a fixing frame, a placing device and a clamping device. The fixing device for coal mine power supply cables provided by the utility model cooperates with each other through a connecting column, a connecting plate and a rotating column. When the cable between the two fixing devices sags downward due to the action of gravity, the bottom of the cable contacts the rotating column, so that the cable is not prone to a large degree of bending, which prolongs the service life of the cable to a certain extent. In addition, through the cooperation of the connecting plate, the limit groove, the bottom plate, the screw rod, the moving plate, the transmission plate, the upper clamping plate, the upper clamping groove, the lower clamping plate and the lower clamping groove, the staff rotates the rotating disk, and the rotating disk drives the screw rod to rotate. Under the action of the screw rod, the moving plate moves downward, and the moving plate drives the upper clamping plate to move through the transmission plate. The cable is clamped under the action of the upper clamping plate and the lower clamping plate, thereby completing the fixing of the cable.

[0004] In view of the above-mentioned related technologies, the inventor believes that the above-mentioned device can only fix electric cables of the same wire diameter during use, and cannot fix electric cables of different wire diameters, which makes it have certain limitations during use. In addition, the installation environment of electric cables in coal mines is complex and diverse. The above-mentioned device cannot properly adjust the installation position of the electric cables during installation. Since the mine walls of coal mines are not located on the same horizontal plane, there is a certain drop between multiple fixing devices, which will cause the cables to be easily bent, thereby easily causing damage to the cables. For this reason, we propose a fixing device for coal mine power supply cables. Utility Model Content
