Wear-resistant feeding hole of hoist

Abstract

The invention provides a wear-resistant feeding hole of a hoist, and belongs to the technical field of hoist accessory equipment. The wear-resistant feeding hole of the hoist comprises a feeding flange and a servo motor, wherein the lower part of the feeding flange communicates with a feeding hopper; a two-way transmission threaded rod is arranged in the feeding hopper; one end of the two-way transmission threaded rod is rotationally connected with an inner side wall of the feeding hopper; the other end of the two-way transmission threaded rod penetrates through the side wall of the feeding hopper, extends out of the feeding hopper and is fixedly connected with a driving end of the servo motor; two sections of threads on the outer surface of the two-way transmission threaded rod are equalin length and opposite in rotating direction; and the outer surface of the two-way transmission threaded rod is sleeved with two transmission threads in a threaded manner. During feeding, materials are accumulated at the lower part of the feeding hopper, and impact of the materials on the feeding hopper is avoided during continuous feeding, so that the effect of protecting the feeding hopper is achieved; and the phenomena that the feeding hopper is seriously abraded and short in service life are avoided by using the material ramming principle.

Description

technical field [0001] The invention belongs to the technical field of hoist accessory equipment, in particular to a wear-resistant feed inlet of a hoist. Background technique [0002] Hoists are large-scale mechanical equipment that are transported by changing potential energy, such as mine hoists, dam crossing hoists, etc. Broadly speaking, elevators, cranes, winches, stabilizers, cranes, hoists, etc. can all be called hoists Machines and hoists generally refer to large-scale mechanical equipment with large power and strong lifting capacity. The transportation process is completed by dragging the flexible wire rope and the transported goods up and down by the power machinery. The wire rope is an indispensable and important part of the hoisting machinery. The main varieties are phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, smooth steel wire rope and so on. [0003] In the prior art, the feeding device of the hoist, the material ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wear-resistant feed inlet of the hoist, which solves the problem of the feed device of the hoist in the prior art. The material directly contacts the wall of the feed hopper and is often worn through. Wear-resistant liners, the use time is too short, which brings a large manufacturing cost problem to the industry
