Abstract

The invention discloses a hand winch with a buffer braking function of a tail rope for construction of a distribution circuit, which comprises a hand winch arranged on a support frame. A tail rope buffer braking mechanism is also arranged on the support frame which is positioned below the hand winch; a secondary grinding center for winding the tail rope is fixed on a shaft, and the shaft can be rotationally arranged on the support frame; a ratchet is integrally arranged at one side of the secondary grinding center; and a pawl matched with the ratchet is arranged on the support frame. The structure of the hand winch is that a main grinding center is fixed on a driven shaft; a set of gear speed reduction transmission mechanism and a set of gear speed acceleration transmission mechanism are respectively arranged on a drive shaft and the driven shaft; a main ratchet is integrally arranged at one side of a main grinding center; and a main pawl matched with the main ratchet is arranged on the support frame. The hand winch with the buffer braking function of the tail rope for construction of the distribution circuit has the characteristics of high security, strong practicability, flexible operation and high efficiency of circuit construction.

Description

technical field [0001] The invention relates to electric power construction equipment, in particular to a shakeable wire tensioner which uses steel wire tail ropes to tighten the cables during the erection and pole construction of large-gear distribution lines. Background technique [0002] The structure of the existing hand winch has a main grinding center for winding and a set of manual gear transmission mechanism, and the braking mechanism of the main grinding center adopts a hoop structure, which is similar to the braking structure of the existing electric bicycle. . In actual construction, because there is only one main grinding center, the pulling force of the tail rope is large, and the risk factor of the operator of twisting and grinding the tail rope is high, which brings hidden dangers to safe production. Contents of the invention [0003] The object of the present invention is to provide a hand winch with a tail rope buffering and braking function, which can fi...
