Detailed Description

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

According to the utility model, as shown in fig. 1-3, the anti-falling device provided by the utility model comprises a guide block 1 and a guide pin shaft 2, wherein the top end of the guide block 1 is connected with a connecting device, an inclined guide groove 11 is formed in the guide block 1, one end of the guide pin shaft 2 is arranged in the guide groove 11, the other end of the guide pin shaft 2 is fixedly connected with an anti-falling pin shaft 3, and the anti-falling pin shaft 3 is supported by an anti-falling supporting plate 4 after extending outwards and does not fall down any more. The anti-falling pin shaft 3 is sleeved with a guide sleeve 5, the guide sleeve 5 is fixed on an anti-falling seat 6, and the bottom end of the anti-falling seat 6 is connected with anti-falling equipment. Because the guide groove 11 is oblique, when the guide block 1 moves downwards, the guide pin shaft 2 slides in the guide groove 11, the guide pin shaft 2 slides towards one side close to the guide sleeve 5, the anti-falling pin shaft 3 connected with the guide pin shaft is pushed to be inserted into the guide sleeve 5 and extend out of the other side of the guide sleeve 5, and when the guide sleeve 5 and the anti-falling seat 6 integrally fall, the anti-falling pin shaft 3 extends outwards and is blocked by the anti-falling supporting plate 4 and prevented from further falling.

The technical scheme of this application is mainly applied to comb-tooth type vertical lift class mechanical parking equipment, and the anti-falling device of this application sets up between the anti-falling equipment of lifting chain and lower part on upper portion, and anti-falling equipment is the lift generally. The connecting device comprises a lifting point bolt 7 connected with a lifting chain at a lifting point, a horizontal plate 8 is fixedly connected with the bottom end of the lifting point bolt 7, the guide block 1 is a vertical plate, and the top end of the guide block 1 is fixed on the bottom surface of the horizontal plate 8.

In this embodiment, the anti-falling seat 6 is a square box, the top surface of the anti-falling seat is provided with a through hole, the hanging point bolt 7 passes through the through hole, the hanging point bolt 7 is sleeved with a spring 9, one end of the spring 9 is abutted against the inner side of the top surface of the anti-falling seat 6, and the other end is abutted against the horizontal plate 8. When the lifting chain at the lifting point of the elevator is loosened or broken, the lifting point bolt 7 and the anti-falling seat 6 can vertically fall down, the spring 9 can automatically rebound in the falling process, the guide block 1 moves downwards relative to the anti-falling seat 6 from a compressed state to a spring-open state, the guide pin shaft 2 can slide in the guide groove 11 towards one side close to the guide sleeve 5, the anti-falling pin shaft 3 connected with the guide pin shaft is pushed to be inserted into the guide sleeve 5 and extend out of the guide sleeve 5, the anti-falling pin shaft 3 is blocked by the anti-falling supporting plate 4 and prevented from falling further after extending outwards, and thus, the anti-falling seat 6 and the elevator below the anti-falling seat can be stopped and no longer fall.

The four corners of the horizontal plate 8 are respectively outwards extended with a section of arc-shaped bulge, the arc-shaped bulge is propped against the inner wall of the anti-falling seat 6, the arc-shaped bulges at the four corners of the horizontal plate 8 can slide in the vertical direction in the anti-falling seat 6, the guide block 1 is prevented from rotating in the horizontal plane, meanwhile, the contact area between the arc-shaped bulge and the anti-falling seat 6 is small, and the friction force between the horizontal plate 8 and the anti-falling seat 6 is reduced.

In this embodiment, the guiding groove 11 is a strip-shaped groove pointing obliquely upwards, and the upper part of the guiding groove points to the direction of the guiding sleeve 5, that is, the guiding pin 2 slides towards the direction close to the guiding sleeve 5 when sliding in the guiding sleeve 5, and the guiding pin 2 and the anti-falling pin 3 are mutually perpendicular.

The anti-falling seat 6 is arranged in a vertical channel steel upright post 10 in a sliding manner, the channel steel upright post 10 is formed by surrounding two channel steels which are oppositely arranged, and also can be formed by surrounding H-shaped steel, the anti-falling supporting plate 4 is fixed on the outer side surface of the channel steel upright post 10, and when the anti-falling seat 6 falls down, the anti-falling supporting plate 4 can support the anti-falling seat 6 through the anti-falling pin shaft 3.

The anti-falling device can realize the anti-falling function, protect the safety of the lifter and the vehicle, ensure that the guide pin shaft slides in the guide groove, stably operates, ensure that the pin shaft does not fall off the groove, ensure that the anti-falling pin shaft is accurately opened and closed, improve the operation safety of the lifter, and prevent the anti-falling device from acting when the lifting chain at any lifting point of the lifter is loosened or broken, thereby avoiding the hidden trouble of overturning or falling of the lifter and the vehicle. The product is small in size, can run inside the lattice type channel steel upright post, is a single module, is convenient to install in cooperation with the lifter, and can be separated from or replaced with the lifter during maintenance.
