Underground coal mine fully mechanized coal mining face high-voltage cable no-twisting rolling device

Abstract

The invention discloses an underground coal mine fully mechanized coal mining face high-voltage cable no-twisting rolling device, and belongs to the field of mine machinery. The underground coal minefully mechanized coal mining face high-voltage cable no-twisting rolling device comprises a low-speed hydraulic motor driving device, a cable conveying device, a 8-shaped device, a frame and the like;and the low-speed hydraulic motor driving device is positioned below the frame, and provides power to the 8-shaped device. The cable conveying device is positioned above the frame, and comprises a cable pressing mechanism, a flat belt friction conveying mechanism and a support roller; and the cable conveying device drags redundant cables on a working surface to convey the cables for the rolling operation of the 8-shaped device. The 8-shaped device is positioned at the middle part of the frame, and comprises a transmission gear set, a longitudinal moving crank slide block mechanism, a transverse moving crank slide block mechanism and a guide sliding mechanism; large and small gears in the transmission gear set provide power to the two sets of crank slide block mechanisms; and when relativeinitial mounting positions of two crankshafts are determined, a rotating speed ratio of the two crankshafts is 1: 2, a cable rolling rod synchronously moves in the longitudinal and transverse directions, and the tail end of the wire rolling rod moves in a similarly 8-shaped trajectory. Through use of the 8-shaped cable winding method, the torsion of the cables in the rolling process can be reduced, and the torsion margin in the cable rolling process after rolling can be effectively counteracted. The device is convenient to operate, and can solve the problems of time and labor wastes in traditional manual cable rolling operation, cable damage and difficult guarantee of the rolling quality in an underground coal mine fully mechanized coal mining face.

Description

technical field [0001] The invention belongs to the field of mining machinery, and in particular relates to a high-voltage cable twist-free winding device for fully mechanized mining working faces in coal mines. Background technique [0002] A variety of electrical equipment needs to be arranged in the fully mechanized mining working face of the coal mine, and various electrical equipment needs to be powered by cables; therefore, various high and low voltage cables are often stored in the fully mechanized mining working face. It not only seriously affects the quality standardization level of the working face, but also easily causes accidents and affects the life safety of mining workers. [0003] Usually the cable is wound on the take-up reel of the ordinary cable coiling device in the same direction; when it is used again, the cable will automatically twist a circle every time it is pulled out. If it does not come out, it will cause internal damage to the cable; the torsio...
