Labor-saving cable take-up and pay-off device

Abstract

The invention relates to the technical field of power equipment, and discloses a labor-saving cable take-up and pay-off device. The labor-saving cable take-up and pay-off device comprises a base; a left mounting seat and a right mounting seat are fixedly mounted on the upper surface of the base; a stop block is fixedly mounted in the left mounting seat; the lower surface of the stop block is fixedly connected with one end of a spring; the other end of the spring is fixedly connected with a pawl; the pawl is movably mounted in the position, located below the stop block, in the left mounting seat; an insertion hole is formed in the pawl; the insertion hole is clamped with a clamping rod; and the pawl is used in cooperation with a ratchet wheel. According to the labor-saving cable take-up and pay-off device, through the arrangement of a torsion spring, a motor drives a take-up barrel to conduct take-up operation; the take-up barrel rotates and enables the torsion spring to start to store energy; after the take-up barrel finishes take-up and a power source is disconnected, the torsion spring releases the accumulated energy, and the energy released by the torsion spring and the energy generated by inertia rotation of the take-up barrel counteract each other; and therefore, inertia rotation of the take-up barrel is prevented, and the cable end cannot be fixed.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a manpower-saving cable retracting and unwinding device. Background technique [0002] A power cable is a common item used for power transmission. Its interior is composed of copper alloy and other materials, while the exterior is made of insulating materials such as rubber. During the use of power cables, it is often necessary to conduct power cables Rewind work. [0003] The existing cable retracting device usually uses a motor to drive the take-up barrel to rotate, so that the cable is wound on the take-up barrel to achieve the purpose of collecting the cable, but in this way, when the take-up barrel is completely collected and the power source is disconnected , due to the effect of inertia, the take-up drum still continues to rotate, which leads to the end of the cable being unable to be fixed or scattered on the ground, which needs to be sorted out by the o...
