Rapid cut-off device for steel wire ropes

Abstract

The invention relates to a rapid cut-off device for steel wire ropes. The device comprises a cut-off support, a casing, a cut-off plummer block, a rotating disk, three pawls, three cutters, a hollow rotating shaft and a handle, wherein the cut-off support is located below the casing, three limiting holes are symmetrically formed in the right side of the casing and along the center axis of the casing respectively, a through hole is formed in the center position of the rotating disk, three pawls are symmetrically mounted in three limiting holes in the right side of the casing and along the center axis of the rotating disk respectively, spirally-circling trapezoid teeth are formed on the right end surface of the rotating disk, trapezoid teeth are formed on bottom end surfaces of the three pawls respectively, the rotating disk is meshed with the three pawls through the trapezoid teeth, the cutters are fixed at the bottoms of the pawls, one end of the hollow rotating shaft is connected with the rotating disk through keys, the other end of the hollow rotating shaft is connected with the casing, and the handle is located in the middle of the hollow rotating shaft. The device can cut off the steel wire ropes in fixed length, the cut is attractive, the equipment layout is compact, the occupation space is small, and the mechanical automation is high.

Description

technical field [0001] The invention relates to the field of rope cutting equipment, in particular to a fast cutting device for steel wire ropes. Background technique [0002] The grab bucket is a bucket that can be opened and closed by grabbing sand, gravel and various bulk goods. It is a spreader that mainly relies on the opening and closing of two combined buckets on the left and right or multiple jaw plates to grab and discharge bulk materials. According to the classification of the shape, the grab can be divided into a shell-shaped grab and a orange-shaped grab. The former is composed of two complete buckets, and the latter is composed of three or more jaw plates; according to the driving method, it can be divided into hydraulic There are two types of grabs and mechanical grabs. [0003] The mechanical grab itself is not equipped with an opening and closing structure, and is usually driven by the external force of a rope or a connecting rod, that is, a rope-type mechan...

AI Technical Summary

Problems solved by technology

The ropes used for rope-type mechanical grabs are usually steel wire ropes, and the steel wire ropes are usually wound into bundles. Before use, they must be cut according to the length of the required wire rope. The two ends of the steel wire rope are easy to burr, so it is not easy to perforate and knot
