Cable pay-off device in coal mine roadway

Abstract

The invention discloses a cable pay-off device in a coal mine roadway. The cable pay-off device comprises a bottom plate arranged horizontally. A positioning rod arranged vertically is fixedly arranged on the bottom plate. The exterior of the positioning rod is sleeved with a cable containing plate. At least two supporting slide pieces are arranged on the bottom plate. Each supporting slide piececomprises a cushion block fixedly arranged on the bottom plate. A bearing frame is installed on each cushion block. A bearing is arranged on each bearing frame. Each bearing is arranged vertically. The top faces of the bearings are attached to the bottom face of the cable containing plate. Each bearing is used for enabling the cable containing plate to rotate relative to the positioning rod in thepay-off process of a cable on the cable containing plate. According to the device, the cable is placed on the cable containing plate, by means of the bottom plate arranged horizontally, after the cable is placed, the cable containing plate can be stable, the device is prevented from inclining or sliding in the cable pay-off or transportation process, safety is improved, by means of the supportingslide pieces, in the pay-off process of the cable, the cable containing plate rotates easily, and straightening of the cable in the pay-off process can be achieved easily.

Description

technical field [0001] The invention belongs to the technical field of cable pay-off in coal mine roadway, and in particular relates to a cable pay-off device in coal mine roadway. Background technique [0002] A large amount of electrical equipment is used in coal mine roadways. Therefore, cables of different types need to be laid during roadway construction to supply power for various electrical equipment. When laying cables, it is necessary to pay out the cables. For example, in the process of cable laying out in a gentle slope inclined shaft, use a steel wire rope reel car to pay out the wires. The cable is wound on the rope reel car, and then the rope reel car is welded on the flat car to pull the cable. The head is unwound. [0003] However, when the cable is transported, the flatbed needs to be fixed, otherwise, it will slide during loading into the car or during transportation, and when the cable is unwound, the flatbed should be placed in the roadway, and it also n...

[0003] However, when the cable is transported, the flatbed needs to be fixed, otherwise, it will slide during loading into the car or during transportation, and when the cable is unwound, the flatbed should be placed in the roadway, and it also needs to be fixed. No, when the cable is thick When pulling the cable, it is easy to drive the flatbed truck to slide
