Description

Elevator hauler vibration-damping rubber pad

Technical Field

The utility model relates to an elevator accessory technical field specifically is an elevator hauler rubber gasket.

Background

During the operation of an elevator, a traction machine generates vibration and noise, and in order to reduce the vibration and noise in a car and reduce the transmission of the vibration and noise of the elevator to a building, a shock absorption pad is generally arranged between a traction machine base and a machine beam of the elevator.

However, the rubber pad is easy to generate permanent deformation (irreversible) when being pressed for a long time under the elevator car or the tractor, so that the rubber performance is aged, electromagnetic waves are generated when the tractor works, ozone generated by the electromagnetic waves is aged, so that the rubber aging is accelerated, and the service life is 3-5 years. And the traction sheave of the hoisting machine is at present not substantially in the centre of the hoisting machine support point, nor generally in the centre of the machine beam. Particularly, in the conventional passenger elevator at present, a traction sheave is basically of a cantilever structure, and the load on a lift car is changed all the time, so that a rubber pad bears certain shearing force, and the failure of the rubber pad is accelerated.

When the installation of present scene, machine roof beam installation accuracy problem, the rubber pad generally adopt the form installation of pressure baffle, nevertheless because the long-time operation of elevator, can cause the bolt of rubber pad not hard up, owing to install with the form of pressure baffle, the rubber pad can block in the both sides of machine roof beam, but front and back both sides are not fixed, can produce the aversion, and the inefficacy of aggravation rubber pad probably causes the risk of hauler landing, has certain safe risk. Aiming at the situation, the elevator traction machine damping rubber pad is designed.

Disclosure of Invention

The utility model aims at the problem that exists and a rational in infrastructure that designs to the aforesaid, the installation is dismantled conveniently, safe and reliable, fixed firm elevator hauler rubber gasket.

The utility model discloses a realize through following technical scheme: the utility model provides an elevator hauler shock pad, it includes the yielding rubber pad body, the top of yielding rubber pad body is provided with a shock pad apron, and the bottom is provided with a shock pad bottom plate of taking the anti-displacement draw-in groove, a circular fixed sleeve is equipped with in the middle of the shock pad bottom plate, and the fixed sleeve is embedded to have one to prevent inclining sleeve to prevent inclining telescopic up-and-down motion through the jump ring restriction of card in the fixed sleeve.

Preferably, the method comprises the following steps: the middle of the shock pad cover plate is provided with a connecting bolt, and the upper part of the connecting bolt is provided with threads for fixing other parts; the lower part is the polished rod, and the bottom is partly up in preventing inclining the sleeve for connecting bolt can only reciprocate, and when the shock pad acted on simultaneously at pressurized and received the shearing force, shock pad apron and connecting bolt reciprocated and played the shock attenuation, owing to restricted other direction movements of connecting bolt simultaneously, reduced the destruction of shearing force to the rubber pad.

Preferably, the method comprises the following steps: the bottom of the shock pad bottom plate is embedded into the edge of the machine beam through the anti-displacement clamping groove, the shock pad bottom plate and the machine beam are buckled on the other edge through the pressing guide plate bolt string and the pressing guide plate, and the shock pad bottom plate and the machine beam are tightly pressed through the pressing guide plate nut, so that the shock pad bottom plate is limited to move.

Preferably, the method comprises the following steps: the host base is installed on the connecting bolt, the connecting bolt can only move up and down through the fixing of the pressing bolt on the host base, so that the shock pad body does not bear shearing force, and when the bolt is loosened, the shock pad can not displace.

The utility model has the advantages of it is following:

1) An anti-tilting structure is designed in the shock pad, so that the shock pad can bear larger lateral force;

2) The bottom of the shock pad is provided with a clamping groove, so that the shock pad is prevented from being displaced after a bolt for mounting the shock pad is loosened.

The utility model has the advantages of reasonable structure, convenient assembly and disassembly, safety, reliability, firmness in fixation and the like.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in fig. 1, the elevator traction machine shock-absorbing rubber pad comprises a shock-absorbing rubber pad body 105, wherein a shock-absorbing pad cover plate 106 is arranged at the top of the shock-absorbing rubber pad body 105, a shock-absorbing pad bottom plate 104 with an anti-displacement clamping groove is arranged at the bottom of the shock-absorbing rubber pad body 105, a circular fixing sleeve 103 is arranged in the middle of the shock-absorbing pad bottom plate 104, an anti-tilting sleeve 102 is embedded in the fixing sleeve 103, and the vertical movement of the anti-tilting sleeve 102 is limited by a clamp spring 101 clamped in the fixing sleeve 103.

The shock-absorbing rubber pad body 105, the shock-absorbing pad cover plate 106, the shock-absorbing pad bottom plate 104, the fixing sleeve 103, the anti-tilt sleeve 102 and the clamp spring 101 form the shock-absorbing pad 1. The utility model discloses a prevent structure of inclining for the shock pad can bear great yawing force, is improving the utility model discloses prolong in the time of bulk strength the utility model discloses a life.

A connecting bolt 107 is installed in the middle of the shock pad cover plate 106, and the upper part of the connecting bolt 107 is provided with threads for fixing other parts; the lower part is a polished rod, the part of the bottom of the polished rod is arranged in the anti-tilting sleeve 102 upwards, so that the connecting bolt 107 can only move up and down, when the shock pad is stressed and is subjected to the action of shearing force, the shock pad cover plate 106 and the connecting bolt 107 move up and down to play a role in shock absorption, and meanwhile, the damage of the shearing force to the rubber pad is reduced due to the fact that the connecting bolt 107 is limited from moving in other directions.

As shown in fig. 2, the anti-shifting clamping groove of the shock pad bottom plate 104 is consistent with the edge shape of the sectional material, and the clamping groove has a certain slope, and the anti-shifting clamping groove can well prevent the bolt of the shock pad from shifting after loosening, so that the utility model discloses the installation is fixed more firmly, thereby improves holistic life.

As shown in fig. 3-4, when the shock pad 1 is placed on the machine beam 2, by external force such as knocking, the bottom of the shock pad base plate 104 is embedded into the edge of the machine beam 2 through the anti-displacement clamping groove, and the other edge is fastened with the shock pad base plate 104 and the machine beam 2 by stringing the pressure guide plate 3 through the pressure guide plate bolt 5 and is pressed by the pressure guide plate nut 4, thereby limiting the movement of the shock pad base plate 104.

The host base 7 is installed on the connecting bolt 107, the connecting bolt 107 can only move up and down through the fixing of the pressing bolt 6 on the host base 7, so that the shock pad body does not bear shearing force, and when the bolt is loosened, the shock pad can not displace.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
