[0022] In order to ensure the stability of clamping and lifting the luggage rack 10, the clamping mechanism 2 is symmetrically arranged in four groups and arranged in a rectangular shape. Two groups of the clamping mechanism 2 include a cylinder 21 horizontally arranged on the clamp frame 1, and the piston rod of the cylinder 21 is fixedly connected to the clamping plate 24 of the L-shaped structure. The clamping plate 24 of the L-shaped structure can be used to clamp the front and rear ends of the limited luggage rack 10, and the bent portion at the lower end of the clamping plate 24 is used to lift the luggage rack 10. The piston rods of the cylinders 21 of a pair of clamping mechanisms 2 located on the left and right sides of the front of the clamping mechanism 2 and a pair of clamping mechanisms 2 located on the left and right sides of the rear of the clamping mechanism 2 move in opposite directions, so that the clamping plate 24 can be retracted from the front and rear sides to the middle to clamp the luggage rack 10.

[0023] In order to facilitate the installation and fixation of the cylinder 21, the upper end surface of the clamp frame 1 is fixedly connected with a cylinder fixing seat 29, and the cylinder 21 is connected to the cylinder fixing seat 29. In this embodiment, two sets of triangular connecting plates are fixedly arranged on the cylinder fixing seat 29, and are screwed to one end of the cylinder 21 by bolts.

[0024] In order to prevent wear on the luggage rack 10 during the clamping and lifting process, a rubber pad 25 is fixedly provided on the inner side of the clamping plate 24 .

[0025] In order to ensure the movement stability of the clamping plate 24, in this embodiment, a sliding rail mechanism is arranged on the clamp frame 1 to realize forward and backward sliding. The clamping mechanism 2 also includes a sliding rail fixing plate 28 fixedly connected to the upper end of the clamp frame 1. The sliding rail fixing plate 28 is fixedly connected with a sliding rail 26. The sliding rail 26 is parallel to the piston rod of the cylinder 21. A slider 27 is slidably connected to the sliding rail 26, and the slider 27 is fixedly connected to the clamping plate 24.

[0026] In order to facilitate the installation and fixation of the slider 27 and the connection between the cylinder 21 and the slider 27, the upper end of the slider 27 is fixedly connected to the sliding seat 23, the sliding seat 23 is connected to the connector 22 connected to the piston rod of the cylinder 21, and the clamping plate 24 is fixedly connected to the end of the sliding seat 23 away from the cylinder 21. In this embodiment, a triangular connecting plate is fixedly provided on the upper end of the sliding seat 23, and the triangular connecting plate is screwed to the connector 22 by bolts.

[0027] In order to better adsorb the luggage rack 10 and prevent the luggage rack 10 from falling off or loosening, the adsorption device 3 is symmetrically arranged in four groups. The adsorption device 3 includes a vacuum suction pipe 32 for connecting to a vacuum generator, and the lower end of the vacuum suction pipe 32 is connected to a vacuum suction cup 34.

[0028] In order to play a safety protection role in the vacuum system, the lower end of the vacuum suction pipe 32 is connected to a vacuum safety valve 33 , and the vacuum suction cup 34 is sleeved on the lower end of the vacuum safety valve 33 .

[0030] In order to detect that the clamp frame 1 has descended to a specified position close to the luggage rack 10 and start the clamping mechanism 2 and the adsorption device 3 through the controller, a plurality of groups of sensors 4 for detecting the luggage rack 10 are fixedly connected to the clamp frame 1. In the present embodiment, two groups of sensors 4 are provided. The sensors 4 can be connected to the PLC controller using distance sensors or other sensors, and the clamping mechanism 2 is also connected to the PLC controller for control.

[0031] Principle of the utility model:

[0032] Before the transfer, the luggage rack 10 has been placed on the shelf. When the operator presses the descending button, the existing lifting mechanism drives the clamp frame 1 to move downward. At this time, the clamping plate 24 connected to the cylinder 21 is in an open state. When the sensor 4 detects that the luggage rack 1 is in place, it sends a signal to the PLC controller. The PLC controller controls the vacuum device to evacuate and controls the cylinder 21 to retract. The vacuum suction cup 34 is adsorbed on the upper end of the luggage rack 10. At the same time, the clamping plate 24 clamps the front and rear ends of the luggage rack 10 and lifts it up to ensure the stability of the transfer.

[0033] Then the lifting mechanism starts to move upward, and moves to the installation station through the existing slide rail mechanism and lowers the clamp frame 1 and the luggage rack 1. After the installation is completed, the operator presses the release button, the adsorption device 3 and the clamping mechanism 2 are released, and after the clamp leaves the luggage rack 10, the operator presses the return button, and the lifting device returns to the standby area with the clamp.
