Detailed ways

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in Figures 1-4, a self-locking device for anti-falling of heavy-duty lifting shelves proposed by the present utility model includes two brackets 1, and two brackets 1 are provided with chute 2 inside, and the two chute 2 are inside A moving column 3 is slidably connected to each other, a lift rack 4 is fixedly connected between the two moving columns 3, and a self-locking mechanism 5 is provided on the two moving columns 3. The self-locking mechanism 5 includes a side wall of one of the moving columns 3. There are a plurality of tooth slots 51, one side of one bracket 1 is fixedly connected with two fixed plates 52, a cylindrical rod 53 is rotatably connected between the two fixed plates 52, and a gear A54 is fixedly connected to the cylindrical rod 53, and the gear A54 and the A plurality of tooth slots 51 are engaged, and one of the brackets 1 is provided with a self-locking assembly 6;

The self-locking assembly 6 includes a fixing rod 61 fixedly connected to one side of one of the brackets 1, a self-locking block 62 is rotatably connected to the fixing rod 61, and an unlocking assembly 7 is provided at the bottom of one side of the self-locking block 62;

One end of the cylindrical rod 53 penetrates one of the fixing plates 52 and extends to the outer side of the fixing plate 52, and one end of the cylindrical rod 53 extending to the outer side of one of the fixing plates 52 is fixedly connected with a gear B55;

The other side of the self-locking block 62 is in contact with the side wall of the gear B55, and the other side of the self-locking block 62 is in contact with one of the teeth on the gear B55;

In this embodiment, traction ropes are fixedly connected to the top ends of the two moving columns 3, and the pulling of the two traction ropes realizes the upward movement of the two moving columns 3, and the two moving columns 3 move along the two chutes respectively. 2 Sliding upward, the two moving columns 3 drive the lifting shelf 4 to move upward. During the upward movement, the gear A54 meshes with a plurality of tooth slots 51, the gear A54 rotates, the gear A54 drives the cylindrical rod 53 to rotate, and the cylindrical rod 53 drives the gear B55 rotates, and the gear B55 rotates clockwise. During the rotation of the gear B55, the teeth on the gear B55 drive the self-locking block 62 to swing up and down. In the initial state, one side of the self-locking block 62 and the The sawtooth counteracts, and the self-locking block 62 drives the two mounting plates A71 to move up and down during the swinging process, and during the movement, the two mounting plates A71 move at both ends of the rotating shaft connected with them, so that the self-locking block 62 swings up and down, thereby realizing Rotation of gear B55;

When the traction rope is broken, under the action of its own weight, the lifting rack 4 drives the two moving columns 3 to move downward, and the two moving columns 3 are prevented from moving downward by the self-locking mechanism 5, thereby solving the problem in the prior art. When the traction rope pulls the lifting rack 4, when the traction rope breaks, it is easy to cause the lifting rack 4 to fall automatically, which is a dangerous problem. Specifically, when the traction rope is broken, the two moving columns 3 stop moving, and the gear A54 stops rotating at this time. , the gear A54 drives the cylindrical rod 53 to stop rotating, and the cylindrical rod 53 drives the gear B55 to stop rotating. The reason why the gear B55 stops rotating is that one side of the self-locking block 62 is in contact with the teeth on the gear B55, thereby preventing the gear B55 from rotating counterclockwise. , and then prevent the cylindrical rod 53 from rotating counterclockwise, thereby preventing the gear A54 from rotating counterclockwise, and the gear A54 meshes with the plurality of tooth slots 51, thereby preventing the moving column 3 from moving downward, thereby preventing the lift rack 4 from falling under its own weight, and then The safety of the device is improved.
