Description

technical field [0001] The invention belongs to the technical field of hoist maintenance equipment, in particular to a labor-saving hoist maintenance door. 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 inspection door of the hoist is usually c...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a labor-saving access door for the hoist, which solves the problem that the access door of the hoist in the prior art is usually connected to the casing by bolts, which is not only inconvenient to open, but also has a large opening weight It is heavy and requires 2-3 people to cooperate to open it. It is extremely inconvenient for on-site maintenance. It can no longer meet the requirements of fast and efficient use, which has brought a large problem of use cost to the industry.
