Abstract

The invention relates to a hoist safety device. The hoist safety device comprises a middle spacer bush (1); positioning blocks are symmetrically arranged on the left side and the right side of the middle spacer bush (1); U-shaped clamps (3) are arranged on the outer sides of the positioning blocks (2), and are open inwards; the U-shaped clamps (3) are connected with the positioning blocks (2) through positioning pins (4); and a steel wire sliding guide groove (5) is formed between each U-shaped clamp (3) and the corresponding positioning block (2). By means of the hoist safety device providedby the invention, a steel wire can be locked and slide within a certain range so as not to bounce out of a pulley groove or turn to one side, usage is reliable, the hoisting safety of objects can be effectively ensured, and meanwhile hoisting operation personnel are well protected.

Description

technical field [0001] The invention relates to a hoist safety device, which belongs to the technical field of ship repairing and building. Background technique [0002] In daily lifting operations, we found that a manual hoist has a high center of gravity during construction, and the steel wire often jumps out of the pulley groove, causing the hoist body to suddenly turn sideways and upside down, which is prone to high falls and collision accidents, posing safety hazards . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gourd safety device for the above-mentioned prior art, which can lock the steel wire to slide within a certain range, and prevent the steel wire from jumping out of the pulley groove and turning over. [0004] The technical solution adopted by the present invention to solve the above problems is: a gourd safety device, which includes a middle spacer, positioning blocks are symmetrically arrang...
