[0064] The setting of the induction switch assembly 5 mainly plays two roles:

[0065] The first function is to stop the operation in an emergency to avoid dangerous accidents; the details are as follows:

[0066] When the safety sensor 54 detects that there is interference between it and the corresponding baffle 43, the signal is transmitted to the controller 6, and the controller 6 automatically issues a command to control the reduction motor 31 to stop running, thereby controlling the operation of the tray frame 1 to stop, thereby avoiding dangerous accidents;

[0067] The second function is that the pallet frame 1 automatically stops running when it runs to both ends of the track 41; the details are as follows:

[0068] In the natural state, the two springs 552 are in a freely extended state, and the trigger rod 553 is located on the side of the first microswitch 52 close to the corresponding safety sensor 54; since the safety sensor 54 is fixedly arranged at one end of the sliding rod 551, during the operation of the tray frame 1, when the outer side of the safety sensor 54 abuts against the inner side of the baffle 43 on the corresponding side, the sliding rod 551 is driven to move toward the direction close to the connecting plate 442, and then the spring 552 begins to contract, and the trigger rod 553 first triggers the first microswitch 52, thereby realizing the deceleration operation of the reduction motor 31; then, the tray frame 1 continues to run, the sliding rod 551 continues to run in the direction close to the connecting plate 442, and the trigger rod 553 secondly triggers the second microswitch 53, thereby realizing the function of stopping the reduction motor 31, and realizing the function of automatically stopping the tray frame 1 when it runs to both ends of the track 41, thereby avoiding dangerous accidents.

In order to prevent the drag chain from being scratched and broken due to the left and right movement of the guide component 44 in the guide groove 42, a diversion pressure plate 45 is installed to divert the movement of the drag chain. Two diversion pressure plates 45 are provided, and the two diversion pressure plates 45 are respectively fixedly arranged on both sides of the two guide plates 441 away from the connecting plate 442, and the two diversion pressure plates 45 are arranged inside the guide groove 42.

[0071] The working principle of the utility model is as follows: when working, first assemble the various components; assemble the support beam 11 and the cross beam 12 by bolts 13 and nuts 14 to form a rectangular pallet frame 1; then install the moving wheel set 21 between the two support beams 11 by bolt assembly; complete the connection of the middle shaft 33 between the two driving wheels 23 by coupling 32 and flat key connector 34; then install the entire pallet frame 1 that has been installed on the guide assembly 44 by quick assembly assembly 46 to complete the entire assembly process; the entire installation process is simple, convenient and fast, and thus has the advantages of high disassembly and assembly efficiency, and is convenient for transportation and storage;

[0072] The cabinet to be moved is fixed on the pallet frame 1; a start-up command is issued through the remote control, and the controller 6 controls the reduction motor 31 to operate, thereby driving the pallet frame 1 to move along the track 41;

[0073] During operation, if the safety sensor 54 detects interference between it and the corresponding baffle 43, it will transmit a signal to the controller 6, and the controller 6 will control the reduction motor 31 to stop running to avoid dangerous accidents;

[0074] During operation, when the tray frame 1 moves to the two ends of the track 41, the shell of the safety sensor 54 abuts against the baffle 6 on the corresponding side, causing the sliding rod 551 to slide in the direction close to the connecting plate 442, thereby driving the trigger rod 553 to move inside the through hole; in the process of the sliding rod 551 sliding in the direction close to the connecting plate 442, the trigger rod 553 first triggers the first micro switch 52, and the first micro switch 52 sends a signal to the controller 6, and the controller 6 controls the reduction motor 31 to decelerate, that is, controls the tray frame 1 to decelerate and move; the trigger rod 553 continues to move with the sliding rod 551, that is, the tray frame 1 continues to approach the end of the track 41, and the trigger rod 553 triggers the subsequent second micro switch 53, and the second micro switch 53 transmits a signal to the controller 6, and the controller 6 controls the reduction motor 31 to stop running, that is, controls the tray frame 1 to stop moving, so as to avoid the tray frame 1 hitting the two ends of the track 41 and causing dangerous accidents such as cabinet tipping over;

[0075] When the pallet frame 1 moves to the specified position, a stop command is issued through the remote controller, and the controller 6 controls the reduction motor 31 to stop running, that is, the pallet frame 1 and the cabinet move to the specified required position;

[0076] The entire cabinet mobile tray device is configured to be assembled, and the installation is convenient, simple, and efficient, and is easy to transport and store. The induction switch assembly is provided to improve the safety performance during use and avoid the occurrence of dangerous accidents.
