Turnover plate assembly of building elevator

Abstract

The utility model discloses a turning plate assembly of a building elevator. The turning plate assembly comprises a turning plate, a driving device and a driving device, wherein the turning plate can rotatably cover a gap between a car and a floor to form a walking channel; a guardrail is arranged on the side edge of the turning plate and provided with a buffering assembly for providing buffering for contact between the guardrail and the bottom face of the lift car. When the guardrail is overturned on the bottom face of the lift car through the overturning plate to be stored in the lift car space, the elastic blocks make contact with the bottom face of the lift car, the elastic blocks drive the supporting columns, the supporting columns drive the limiting plates, the limiting plates drive the stress plates through the adjusting bolts, the stress plates drive the springs to elastically deform, and the bottoms of the springs stretch and elastically deform with the fixing positions of the bottoms of the springs and the guardrail as stress points. At the moment, elastic deformation of the springs and the elastic blocks jointly provides buffering damping performance, the problem that large noise is generated due to hard contact between the guardrails on the turning plates and the bottom face of the lift car is solved, and therefore the riding feeling of operators in the lift car is improved.

[0009] The guardrail is welded and fixed on both sides of the turnover plate.

[0010] It also comprises a car of the building hoist, and the car has a turnover plate rotatably installed on the car bottom surface through a hinge and a floor slab spaced apart from the car.

[0011] The guardrail is provided with a sliding through hole; the buffer assembly comprises a support column slidably penetrating in the sliding through hole of the guardrail, the bottom of the support column is fixed with an elastic block capable of elastic deformation, and the elastic block is larger than the sliding through hole of the guardrail.

[0012] The top of the support column is fixed with a limiting plate; a stress plate is slidably installed on the support column, and both ends of the stress plate are fixedly connected with the guardrail through springs; the limiting plate is screwed through an adjusting bolt, and the adjusting bolt is screwed on the stress plate.

[0013] The limiting plate and the stress plate are both provided with threaded through holes for the screwing of the adjusting bolt.

[0014] The utility model discloses a beneficial effect lies in: the guardrail is through the flap and is turned over in the car bottom surface and is received in the car space, and the elastic block contacts the car bottom surface, and the elastic block drives the support column, and the support column drives the limiting plate, and the limiting plate drives the stressed plate through the adjusting bolt, and the stressed plate drives the spring and occurs the elastic deformation, and the spring bottom portion is with the guardrail fixed place as the stress point and occurs the lengthening elastic deformation, and the elastic deformation of spring and elastic block occurs the buffer damping nature jointly at this moment, and the problem that the guardrail on the flap and the car bottom surface hard contact produce the greater noise is solved, thereby the riding feeling of the operating personnel in the car is improved.

[0018] The technical scheme of the utility model is further described below, but the scope of protection is not limited to the description.

[0019] As Figs. 1-2 Indicated.

[0020] The flap assembly of a building elevator of the application comprises:

[0021] The flap 2 rotatablely installed on the car bottom surface 11 through the hinge, is received in the car 1 space when the flap 2 rotates inward and is opened when the flap 2 rotates outward, and the gap between the car 1 and the floor 12 is formed to form a walking channel.

[0022] The guardrail 21 is welded on both sides of the flap 2, and the buffer assembly 3 is installed on the guardrail 21, and the buffer assembly 3 provides the buffer for the contact between the guardrail 21 and the car bottom surface 11.

[0023] The guardrail 21 is provided with a sliding through hole;

[0024] The buffer assembly 3 comprises the support column 31 slidably penetrated in the sliding through hole of the guardrail 21, the elastic block 32 capable of elastic deformation is fixed at the bottom of the support column 31, the elastic block 32 is greater than the sliding through hole of the guardrail 21, and the limiting plate 33 is welded and fixed at the top of the support column 31;

[0025] The force receiving plate 34 is slidably installed on the support column 31, and both ends of the force receiving plate 34 are fixedly connected with the guardrail 21 through the springs 35; the adjusting bolt 36 is screwed through the limiting plate 33, and the adjusting bolt 36 is screwed on the force receiving plate 34; the limiting plate 33 and the force receiving plate 34 are both provided with threaded holes for screwing the adjusting bolt 36; when the elastic deformation stroke distance of the spring 35 needs to be adjusted, the adjusting bolt 36 is first screwed downward from the limiting plate 33 to extend, and then is screwed on the force receiving plate 34 without penetrating through, so that the limiting plate 33 and the force receiving plate 34 are spaced apart by a distance, so that the elastic deformation stroke distance of the spring 35 can be adjusted.
