Abstract

The utility model relates to a buffer mechanism, which comprises a base and a buffer, and is characterized in that the base is in a C shape, a square support pipe is fixedly arranged in the base through an end sealing plate, a buffer seat is arranged in the square support pipe, the upper part of the buffer seat is fixedly provided with the buffer through a connecting element, the connecting element is a screw bolt and is connected with a screw nut, and in addition, a parallel gasket and a spring gasket are also padded between the screw bolt and the screw nut. The buffer mechanism can be used at two sides of the bottom of a lift car in an elevator, four groups of buffer mechanisms in total are used for supporting the lift car, the square support pipe is added as a buffer region, the buffer effect of the lift car is improved, the stability of the lift car is ensured, and the safety of the elevator is guaranteed.

Description

Damper mechanism

Technical field:

The utility model relates to a kind of damper mechanism of the firm effect of buffering that car risen for cage lifter.

Background technology:

in the use of cage lifter, line position protection to car is particularly important, original mechanism increases spring as energy disperser in the bottom of car, it makes the kinetic energy of car or counterweight and the elasticity sex change energy that potential energy is converted into spring, antagonistic force due to spring, car or counterweight are slowed down, when spring-compressed after end position, spring is wanted the elasticity sex change energy in the buffer release process, car still will rebound to rise to produce and clash into, velocity of impact is higher, bounce-back speed is larger, like this, simple employing spring is as the buffering to car, can cause the car distortion or rock, safety factor to whole cage lifter impacts.

Summary of the invention:

The technical matters that the utility model solves is to provide a kind of for cage lifter, has the secondary buffer effect, guarantees the damper mechanism of car stability.

The technical scheme in the invention for solving the technical problem is: a kind of damper mechanism, comprise base and energy disperser, described base is the C type, be fixed with supporting square tube by head plate in this base, be provided with buffer box in this supporting square tube, pass through the attaching parts fixed bumper above this buffer box.

Further, in order to ensure the stable connection of buffer box and energy disperser, described attaching parts is that screw bolt and nut connects.

Further, when producing impulse force in order to ensure car, avoid producing rigid collision between buffer box and energy disperser, also be lined with parallel packing ring and spring washer between described screw bolt and nut.

The beneficial effects of the utility model are: this damper mechanism is used for the both sides of cage lifter car bottom, have four groups of damper mechanism and support car, increased supporting square tube as buffer zone, improved the buffering effect of car, guarantee the stability of car, ensure the safety of cage lifter.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is that in the utility model, horizontal plate forms schematic diagram;

Fig. 2 is the enlarged drawing at A place in Fig. 1;

Fig. 3 is the schematic diagram of B direction in Fig. 1;

Fig. 4 is the front view of buffer box in the utility model;

Fig. 5 is the birds-eye view of buffer box in the utility model.

In figure: 1, base 2, head plate 3, supporting square tube 4, buffer box 5, energy disperser 6, bolt 7, nut 8, parallel packing ring 9, spring washer.

The specific embodiment:

A kind of damper mechanism as shown in Fig. 1～5, comprise base 1 and energy disperser 5, described base 1 is the C type, be fixed with supporting square tube 3 by head plate 2 in this base 1, be provided with buffer box 4 in this supporting square tube 3, by attaching parts fixed bumper 5, this head plate 2 is arranged in supporting square tube 3 and can slides up and down along the cavity in supporting square tube 3 above this buffer box.

Further; in order to ensure the stable connection of buffer box and energy disperser, described attaching parts is that bolt 6 is connected connection with nut, and described head plate (2) top is square; offer connecting bore at square place, four angles, dock this square bottom with energy disperser 5.

Further, as shown in Figure 2, when producing impulse force in order to ensure car, avoid producing rigid collision between buffer box and energy disperser, also be lined with parallel packing ring 8 and spring washer 9 on 7, described bolt 6 and nut.

This damper mechanism is used for the both sides of cage lifter car bottom, has four groups of damper mechanism and supports car, has increased supporting square tube 3 as buffer zone, has improved the buffering effect of car, guarantees the stability of car, ensures the safety of cage lifter.

It is emphasized that, it is more than better implementation column of the present utility model, be not that utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
