Description

Shock attenuation car of elevator

Technical Field

The invention belongs to the technical field of elevators, and particularly relates to a damping car of an elevator.

Background

Elevator car is at the fast-speed in-process that reciprocates, and the vibration of elevator can aggravated to irregular air current, and elevator itself also can produce the vibration simultaneously, and the frequency that produces externally is close elevator self vibration frequency, and whole elevator can produce resonance, has increaseed the vibration of elevator, is located the interior worry panic of the personnel of taking in elevator car, causes uncomfortable sense.

The lift car of the lifting elevator with the announcement number of CN212799220U solves the problem that the vibration of the car body cannot be slowed down in the lifting process of the original elevator, so that the comfort of passengers is improved. It includes the car body, the inner chamber of car body is connected with the loading board, the equal fixedly connected with baffle-box in the left and right sides of car body inner chamber bottom, through setting up the loading board, when car body vibrations, make the loading board remove at the inner chamber of car body, the loading board drives the barrel and extrudes first pressure spring at the surface lapse of traveller, first pressure spring supports the barrel under the reaction force, thereby make the barrel slow down vibrations to the loading board, the barrel drives the slide bar and extrudes the fly leaf at the internal surface slip of slide simultaneously, make the fly leaf remove and extrude the second pressure spring, through setting up above structure, possess the elevator at the in-process that goes up and down, can slow down the advantage of vibrations to the car body.

Barrel and traveller that cup joint each other are set up to the below of loading board in the above-mentioned patent, the supporting role that the loading board received mainly leans on cup jointing on the traveller and be located the first pressure spring of barrel below, the loading board bears decurrent gravity and can not disperse in the daily use of elevator, bearing pressure is great, first pressure spring receives serious compression in the direction of gravity, first pressure spring can exert elastic buffer's effect and not obvious this moment, thereby the shock attenuation effect is not showing under the great condition of loading board bearing in this scheme, still remain to improve.

Disclosure of Invention

The invention aims to provide the damping lift car of the elevator, which has better damping effect, aiming at the defects in the prior art.

The damping lift car of the elevator comprises a lift car body, wherein a bearing plate is connected in the lift car body, a damping mechanism is arranged below the bearing plate, the damping mechanism comprises supporting arms which are distributed along four directions of the lift car in a dispersing manner, the supporting arms are arranged in an inverted V shape between every two supporting arms, the upper ends of the supporting arms are hinged with the bearing plate, and the lower ends of the supporting arms are rotatably connected with sliding blocks; the lateral wall of car is connected with the slide rail, and slider sliding connection is connected on the slide rail, is connected with the spring between slider and the car lateral wall.

The working principle of the scheme is as follows: when taking place vibrations, the loading board has the trend of flickering from top to bottom, and damper receives the pressure of size infinitesimal this moment, and the support arm rotates, and the slider slides on the slide rail simultaneously, and the spring is compressed and resets, and damper plays cushioning effect in a series of transmission processes of power to performance absorbing effect.

The beneficial technical effect of this scheme is: gravity or pressure that damper will bear in this scheme are to dispersion all around, and prior art under the same condition, the pressure reduction that every spring and support arm bore, can exert better shock attenuation effect.

Further, the bottom and the car bottom of slide rail are connected, set up the spout of horizontal setting on the slide rail, slider and spring all are located the spout. The slider is located the spout, and the slider receives blockking of the wall body of sliding groove and ensures that the slider is steady to slide in the spout at the slip in-process to ensure to reach better shock attenuation effect.

Furthermore, the one end that car lateral wall was kept away from to the spout is equipped with the spacing blend stop of eminence spout bottom. The condition that vibration amplitude is big can appear occasionally when the elevator meets accident, and slider drops from the spout when this scheme can avoid vibrations great.

Furthermore, the longitudinal section of spout is "protruding" font, and the slider is located the one end of spout broad, and the junction of slider and support arm is located the one end of spout narrower. The sliding groove plays a better role in limiting the sliding track of the sliding block.

Furthermore, the slide rail is cylindrical, the spring sleeve is arranged on the slide rail, a through hole for the slide rail to pass through is formed in the slide block, the two opposite slide blocks share one slide rail, and the two slide rails are connected in a crossed manner. The sliding block in the scheme can not be separated from the sliding rail under any accident condition, and the structure is more compact and firm.

Further, the bottom of the slider is in contact with the bottom of the car. The bottom of the car supports the sliding block, and the sliding rail is guaranteed to bear less pressure.

Further, the contact surface of slider and car bottom is the smooth surface.
