Embodiment 1

[0028] This embodiment discloses a shock absorbing device for an elevator traction mechanism, which includes a first connecting piece, several intermediate shock absorbing devices and a second connecting piece 5; The shock absorbing device is located between the first connecting piece and the second connecting piece 5, and the second connecting piece 5 is fixed above the load-bearing beam 6 by bolts and other fixing pieces. In this embodiment, the damping efficiency of the traction mechanism is effectively improved by using the three-layer damping device, and the safety of the elevator is improved. The first connector is the first shock-absorbing barrier of the traction mechanism, the length direction of the first connector is parallel to the side of the base 1, and its length is consistent with the side of the base 1; the front and rear ends of the first connector are both In the open state, the first connecting piece is composed of a base plate 21 and a side plate 22. The ba...

Embodiment 2

[0033] In this embodiment, in order to further improve the damping performance of the shock absorbing device, the damper 33 in the middle damping layer can be replaced with the cylinder shock absorber in the automobile suspension system, and the cylinder shock absorber adopts the Commonly used shock absorbers, when working, the piston rod in the barrel shock absorber drives the piston to move up and down repeatedly in the working cylinder, so that the oil in the working cylinder repeatedly flows from one cavity through different pores to another cavity Inside, through the friction between the hole wall and the oil and the internal friction between the oil molecules, a damping force is formed on the vibration, so that the vibration energy is converted into heat energy of the oil to perform shock absorption and suppress the beating of the shock-absorbing spring 32 .

Embodiment 3

[0035] In this embodiment, the first shock-absorbing layer 31 is composed of an upper shock-absorbing member, a lower shock-absorbing member, a pillar connecting the shock-absorbing members, and a shock-absorbing block, and the pillar connects the sides of the upper shock-absorbing member and the lower shock-absorbing member. Side, the pillar is made of rubber material; the upper shock absorber and the lower shock absorber are integrally formed of plastic, and the shock absorber is a hollow type shock absorber; the shock absorber is installed between the upper shock absorber and the lower shock absorber In the middle position, the damping block is made of high elastic rubber, and the shape of the shock absorbing block can be adjusted according to the actual use; the shock absorbing block and the pillar play a double damping effect on the first shock absorbing layer, further improving the overall shock absorption The damping performance of the device.

Abstract

The invention provides a shock absorption device of a traction mechanism of an elevator. The shock absorption device comprises a first connecting member, a plurality of middle damping devices and a second connecting member. The shock absorption device is characterized in that the first connecting member is mounted below a base, the middle damping devices are located between the first connecting member and the second connecting member, and the second connecting member is fixed above a bearing beam; a length direction of the first connecting member is parallel to side edges of the base, and the length of the first connecting member is consistent with that of the side edges of the base; both front and rear ends of the first connecting member are in an open state, the first connecting member consists of a substrate and side plates, the substrate is placed at the bottom of the base, the side plates are arranged in bilateral symmetry along the length direction of the first connecting member, connecting holes which are used for mounting fixing members are separately formed in the two ends of the substrate, and the substrate is connected with the base through the fixing members. The shock absorption device provided by the invention has the beneficial effects that through three layers of damping devices, the shock absorption efficiency of the traction mechanism is effectively increased, and the safety of the elevator is improved.

Description

technical field [0001] The invention relates to the technical field of damping for a traction machine, in particular to a damping device for an elevator traction mechanism. Background technique [0002] In the existing elevators, the lifting motion of the elevator car is generally pulled by a traction machine. During the working process of the elevator traction machine, especially during the rapid lifting of the traction car, the elevator traction machine often produces vibrations, which affects the stability of the elevator operation. In order to solve this problem, rubber shock absorbing pads or shock absorbing springs are generally installed at the bottom of the elevator traction machine for shock absorption; but the load-bearing capacity of rubber shock absorbing pads is weak, and it cannot be used for the shock absorption of heavy traction machines. Shock, the scope of application is small; the shock-absorbing spring itself will reciprocate (jump) during shock absorpti...
