Abstract
The utility model discloses an anti-falling device for a lifting and rotating type parking equipment trolley. The anti-falling device comprises a lifting platform (1) of the trolley and a chain (3), wherein the chain (3) is used for driving the lifting platform (1) to lift up and down along an upright post (2); an anti-falling plate (4) is fixed on the upright post and is hinged with a clamping pin plate (5); a stop rod (6) is fixed on the clamping pin plate (5); one end of a torsion spring (7) is acted upon the clamping pin plate (5); the other end of the torsion spring (7) is acted upon the anti-falling plate (4); the stop rod (6) is pressed against the chain (3); the front of the clamping pin plate (5) is hook-shaped; an anti-falling hanging plate (8) is fixed on the lifting platform (1); and a clamping rib (81) matched with the hook part at the front end of the clamping pin plate (5) is formed on the anti-falling hanging plate (8), so that the phenomenon that the lifting platform cannot be fallen on the ground once the chain is disconnected during the working process of the trolley can be ensured.
Description
Technical field:
The utility model relates to the ascending and descending parking device technical field, more specifically to a kind of elevating stage falling proof device of chassis of the rotary parking apparatus that goes up and down.
Background technology:
The elevating stage of the chassis of existing up-down rotary parking apparatus is in transporting the process of dolly, if chain is once rupture, then elevating stage can be born, thereby cause the automobile damage.A lot of manufacturers do not design the anti-drop device of elevating stage, and are very dangerous in the use like this.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and a kind of falling proof device of the rotary parking apparatus chassis that goes up and down is provided, and it can guarantee chassis in the course of the work, breaks off and can not allow elevating stage born once chain takes place.
The technological solution of the utility model is following:
The falling proof device of up-down rotary parking apparatus chassis, comprise chassis elevating stage, be used to drive the chain of elevating stage along the column oscilaltion, on column, be fixed with anti-fall plate; Be hinged with the bayonet lock sheet on the anti-fall plate, be fixed with pin on the bayonet lock sheet, torsion spring one end active force in bayonet lock sheet, other end active force in anti-fall plate; Pin is pressed on the chain; The front portion of bayonet lock sheet is hook-shaped, is fixed with anti-fall link plate on the elevating stage, forms the card muscle that matches with bayonet lock sheet front end hook portion on the anti-fall link plate.
The beneficial effect of the utility model is:
It can guarantee chassis in the course of the work, can not allow elevating stage born once take place chain to break off.
Description of drawings:
Fig. 1 is the installation site sketch map of the utility model on chassis
Fig. 2 is the structural representation under the utility model normal operating conditions
Fig. 3 breaks off the structural representation of back the utility model for chain
Among the figure: 1, elevating stage; 2, column; 3, chain; 4, anti-fall plate; 5, bayonet lock sheet; 6, pin; 7, torsion spring; 8, anti-fall link plate; 81, card muscle.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 3, the falling proof device of up-down rotary parking apparatus chassis, comprise chassis elevating stage 1, be used to drive the chain 3 of elevating stage 1 along column 2 oscilaltions; On column 2, be fixed with anti-fall plate 4; Be hinged with bayonet lock sheet 5 on the anti-fall plate 4, be fixed with pin 6 on the bayonet lock sheet 5, torsion spring 7 one end active forces in bayonet lock sheet 5, other end active force in anti-fall plate 4; Pin 6 is pressed on the chain 3; The front portion of bayonet lock sheet 5 is hook-shaped, is fixed with anti-fall link plate 8 on the elevating stage 1, forms the card muscle 81 that matches with bayonet lock sheet 5 front end hook portions on the anti-fall link plate 8.
Operating principle: see shown in Figure 2ly, when chain 3 operate as normal, chain is upright tensioning shape, and pin 6 is owing to the power that has received torsion spring 7 leans against on the chain 3, and this moment, all were normal.
See shown in Figure 3ly, when chain 3 broke off, pin 6 was not owing to receive stopping of chain 3, at this moment, bayonet lock sheet 5 counter-clockwise swings under the power effect of torsion spring 7, just in time the hook portion dogging of bayonet lock sheet 5 front ends is on card muscle 81.
In anti-fall plate 4, because pin 6 is fixed together with bayonet lock sheet 5, pin 6 is Elastic Contact to torsion spring 7 one end active forces when contacting with chain 3 in bayonet lock sheet 5, other end active force.And after chain broke off, pin was no longer stressed, and the front end hook portion of bayonet lock sheet 5 is just in time stretched out dogging forward at card muscle 81, thereby makes elevating stage 1 be unlikely to fall.
Claims (1)
1. the falling proof device of up-down rotary parking apparatus chassis; Comprise chassis elevating stage (1), be used to drive the chain (3) of elevating stage (1) along column (2) oscilaltion, it is characterized in that: on column (2), be fixed with anti-fall plate (4), be hinged with bayonet lock sheet (5) on the anti-fall plate (4); Be fixed with pin (6) on the bayonet lock sheet (5); In anti-fall plate (4), pin (6) is pressed on the chain (3) torsion spring (7) one end active forces in bayonet lock sheet (5), other end active force, and the front portion of bayonet lock sheet (5) is hook-shaped; Be fixed with anti-fall link plate (8) on the elevating stage (1), form the card muscle (81) that matches with bayonet lock sheet (5) front end hook portion on the anti-fall link plate (8).
