Zero-breakage-rate hoister

Abstract

The invention discloses a zero-breakage-rate hoister which comprises a base, a first motor, a cargo limiting mechanism, a second motor and a sliding plate. Self-locking rollers are fixed to the left side and the right side of the lower end face of the base, a dustproof cover covers the outer side of a winch, a steel wire rope is wound around the winch, and the steel wire rope penetrates through a rope penetrating hole to be connected with connecting rings; and the connecting rings are fixed to the left side and the right side of the upper end face of an object placing plate, the cargo limiting mechanism is fixed to the lower end face of the object placing plate and penetrates through the object placing plate, the sliding plate is slidably connected between sliding ways, the sliding ways are fixed to the front end face of a supporting plate, a second hydraulic cylinder is fixed to the rear end face of the sliding plate, and the rear side of the second hydraulic cylinder is connected with a push plate through a second piston rod. According to the zero-breakage-rate hoister, after cargo are placed on the object placing plate, a limiting frame moves upwards, the cargo are conveniently limited, and the situation that the cargo accidentally fall off from the object placing plate and are broken is avoided.

Description

technical field [0001] The invention relates to the technical field related to hoists, in particular to a hoist with zero breakage rate. 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, etc. It is inconvenient for the existing hoist to limit the cargo before lifting the cargo. During the...

Problems solved by technology

[0003] The purpose of the present invention is to provide a hoist with a zero breakage rate to solve the problem that the existing hoist proposed in the background technology is inconvenient to limit the goods before lifting the goods. The platform was accidentally dropped and broken, and it was difficult to automatically complete the unloading operation after the lifting operation was completed.
