The technical scheme has the defects that: in the process of transporting goods from a high place to a low place, due to the fact that the goods with large weight are arranged on the suspension cage, when the suspension cage reaches the ground, impact can be formed on the ground, the generated impact force is directly transmitted to the suspension cage, the longer the time is, the longer the service life of the suspension cage can be affected, and therefore improvement is needed.

Disclosure of Invention

The utility model provides a not enough to prior art, the utility model provides a lifting machine with buffering protection architecture, it utilizes buffer spring's elastic force to reduce the cage to the impact force on ground, increases the practical life of cage, improves economic benefits.

In order to achieve the above purpose, the utility model discloses a technical scheme is: the utility model provides a lifting machine with buffering protection architecture, which comprises a frame, the frame top is provided with the lifting machine, around being equipped with wire rope on the lifting machine, the wire rope other end is provided with the couple, it has buffering subassembly to articulate on the both sides inner wall of frame, buffering subassembly includes buffer board and buffer spring, buffer board bottom activity articulates at the frame inner wall, the middle part then is fixed mutually with the frame inner wall of eminence by buffer spring traction, make buffer board and frame lateral wall form opening contained angle up, can touch the buffer board downwards when lifting by crane the cage overweight, the elastic force that utilizes buffer spring reduces the cage impact force to ground when descending.

Through adopting above-mentioned technical scheme, the elastic force that utilizes the spring reduces the cage to the impact force on ground when descending, and is provided with the shock attenuation cushion in the buffer bottom, avoids buffer to improve its life when impacting ground, increases economic benefits.

The utility model discloses further set up to: the buffer spring is in a stretching state in a normal state, and can be changed into a state with a normal length under the upward action of the suspension cage when the suspension cage is lifted upwards.

The utility model discloses further set up to: buffer spring sets up a plurality ofly, and a plurality of buffer spring one end are connected at the upper surface of buffer board, and the other end is connected in the frame, utilizes buffer spring's elastic force to reduce the cage impact force to ground when descending.

The utility model discloses further set up to: the buffer components are symmetrically hinged to the left side and the right side of the rack.

The utility model discloses further set up to: the horizontal included angle between the buffer assembly and the rack is 60 degrees.

The utility model discloses further set up to: and a damping rubber pad is arranged at the bottom of the buffer component.

The utility model has the advantages that: the utility model discloses a simple structure, the elastic force that can effectual utilization spring reduces the cage impact force to ground when descending, and is provided with the shock attenuation cushion bottom buffer, avoids buffer to improve its life to buffer's damage when assaulting ground, increases economic benefits.

fig. 2 is a left side view of a hoist with a buffer protection structure;

in FIGS. 1 to 2: 1-a hoisting machine; 2-a steel wire rope; 3-hooking; 4-a frame; 5-a buffer spring; 6-a buffer plate; 7-a shock-absorbing rubber cushion; 8-a cross beam; 9-bottom plate.

Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Referring to fig. 1 and 2, a lifting machine with a buffer protection structure comprises a frame 4, a cross beam 8 is vertically arranged on the frame 4 in a symmetrical mode, the cross beam 8 is used for strengthening the action of the frame 4, a lifting machine 1 is arranged at the top of the frame 4, a steel wire rope 2 is wound on the lifting machine 1, one end of the steel wire rope 2 is fixedly connected with the lifting machine 1, a hook 3 is arranged at the other end of the steel wire rope 2, the hook 3 can be used for hanging a suspension cage or other heavy objects, a buffer device is hinged to the side wall of the frame 4 and comprises a bottom plate 9, a buffer plate 6 and buffer springs 5, the bottom plate 9 is fixed to the side wall of the frame 4, the buffer plate 6 is hinged to the inner side of the bottom plate 9, the buffer springs 5 are arranged in a plurality, one ends of the buffer springs 5 are connected to the upper surface of the buffer plate 6, the other, more effectively increase the cage when descending in ground, the buffer device makes its better entering buffer state with the contact angle of cage, and the buffer device bottom is provided with shock attenuation cushion 7, utilizes shock attenuation cushion 7 can effectually avoid buffer device to improve its life when assaulting ground, increases economic benefits.

When the elevator is used for specifically implementing, after the cage or the heavy object is hoisted by the elevator, when the cage or the heavy object is put down, the buffer plate of the buffer device is touched when the cage or the heavy object is lifted, the buffer plate is overturned, the impact force of the cage on the ground when the cage is descended is reduced by utilizing the elastic force of the spring, and the shock absorption rubber cushion is arranged at the bottom of the buffer device, so that the buffer device is prevented from being damaged when impacting the ground, the service life of the buffer device is prolonged, and the economic benefit is increased.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
