the anti-falling unit comprises a hook, a first stop block is fixedly arranged on the lifting machine in a matched mode, and a second stop block is fixedly arranged on the rail in a matched mode.

Further, the chain is fixedly connected through a connecting piece.

Furthermore, lifting machine lower extreme fixed mounting has cargo platform mounting platform, two cargo platform mounting platform simultaneously with cargo platform fixed connection, two cargo platform mounting platforms all are used for supporting cargo platform, cargo platform pass through a plurality of bolts with cargo platform mounting platform is fixed.

Further, the chain is fixed on the steel wire rope tensioning device through a bolt.

Furthermore, one side of the lifting mechanism, which is close to the track, is fixedly provided with a first auxiliary wheel, a first driving wheel, a second auxiliary wheel and a second driving wheel from top to bottom.

Further, the hook comprises a hook body and a hook body, the hook body and the hook body are integrally formed, and the hook body is fixedly arranged on one side, close to the first stop block, of the hook body.

Furthermore, the second stop block is fixedly arranged on one side, close to the first stop block, of the track.

The implementation of the utility model has the following beneficial effects:

1. the lifting mechanism is simple in structure principle, and by adding the first stop block, the second stop block and the hook, the safety of the lifting mechanism can be improved, and the phenomenon that a chain is broken in the lifting process of the loading platform, so that people or articles below the loading platform are in a dangerous condition is prevented.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to the attached drawings 1-2 of the specification, the technical problem to be solved in this embodiment is that the existing stereoscopic parking space has insufficient connection strength, a chain is prone to be broken, and a task of a lower-layer vehicle is prone to be damaged after the chain is broken, so that a fall-preventing device is provided, which includes:

the device comprises two lifting machines 7, wherein the two lifting machines 7 are arranged in bilateral symmetry, each lifting machine 7 comprises a rail 8, each rail 8 is provided with a lifting machine 7, each lifting machine 7 is connected with a steel wire rope tensioning device 2 through a steel wire rope, the upper end of each steel wire rope tensioning device 2 is fixedly connected with a chain 4 through a connecting piece, and the front side of each lifting machine 7 is provided with a falling prevention unit;

the hoister 7, the steel wire rope tensioning device 2 and the chain 4 are sequentially arranged along the track 8 from bottom to top;

the anti-falling unit comprises a hook 1, a first stop block 5 is fixedly arranged on the lifting machine 7 in a matched mode with the hook 1, and a second stop block 6 is fixedly arranged on the track 8 in a matched mode with the hook 1.

The chain 4 is fixedly connected through the connecting piece 3.

7 lower extreme fixed mounting of lifting machine has cargo platform mounting platform, two cargo platform mounting platforms simultaneously with cargo platform fixed connection, two cargo platform mounting platforms all are used for supporting cargo platform, and cargo platform is fixed with cargo platform mounting platform through a plurality of bolts.

The chain 4 is fixed on the steel wire rope tensioning device 2 through a bolt.

One side of the hoister 7 close to the rail 8 is fixedly provided with a first auxiliary wheel, a first driving wheel, a second auxiliary wheel and a second driving wheel from top to bottom.
