Large take-up reel used for engineering

Abstract

The invention provides a large take-up reel used for engineering. The large take-up reel comprises an upper frame, a winding roll, a coil spring and a lower frame, wherein the upper frame, the winding roll, the coil spring and he lower frame are arranged in sequence from top to bottom; the two frames are fixedly connected, a round cavity used for containing the winding roll and the coil spring is formed between the two frames; the opening of the cavity is provided with a line discharging device; the upper frame is provided with a lock mechanism used for controlling the winding roll to rotate; the winding roll comprises a pay-off rack and a connecting shaft; the upper end and the lower end of a connecting shaft are respectively in rotatable connection with the two frames; the inner radial end and the outer radial end of the coil spring are respectively in fixed connection with the bottom of the connecting shaft and the lower frame; one end of a cable passes through the inside of the connecting shaft to be connected with power supply equipment, and the other end of the cable passes through the line discharging device to be connected with electric equipment; when the cable is discharged, the cable drives the winding roll to rotate, energy is stored through the coil spring, and on the contrary, when the coil spring is reset and the winding roll is driven to reversely rotate, a cable take-up work is finished. The large take-up reel is smooth in taking up and paying off, line discharging directions and length can be regulated at will, and a working range is large.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a large-scale wire take-up reel for engineering. Background technique [0002] In the case of field work or insufficient power supply, power supply vehicles are widely used as necessary energy supply facilities. When in use, one end of the cable is connected to the power supply of the power supply vehicle and the other end is connected to the electrical equipment. It provides an important guarantee for the continuous work of various engineering equipment. Considering the long length of the cable, it is necessary to set a take-up reel on the power supply vehicle to realize the fast and orderly take-up and release of the cable. The existing power supply vehicles are not equipped with corresponding take-up and release devices, and most of the take-up and take-off devices used in other fields are simple in structure, which can only play the role of stacking the ...

Problems solved by technology

Although the known patent controls the overall rotation of the take-up reel by setting a 7-shaped curved bolt and a bolt structure, its structure is quite complicated, and there is no effective solution to the control problems of cable wear and outgoing direction method
