The clamping plates 41 are provided with two pieces, and the two clamping plates 41 are located on both sides of the lifting seat 32. A passage is formed between the two clamping plates 41, and the outlet of the passage can be connected to the opening 2. Both clamping plates 41 slide in the length direction of the housing 1. The conveying belt 42 is provided in the direction where the clamping plate 41 approaches the other clamping plate 41. In the embodiment of the present application, the driving structure 44 is preferably a transmission shaft. The driving structure 44 is installed on the side wall of the clamping plate 41, and the conveying belt 42 is wound around the outside of the driving structure 44.

[0037] When the staff uses the heavy-load elevator, the staff can connect the conveyor belt to the position of the opening 2 at any time according to production needs, and then the conveyor belt transports the PCB circuit board toward the position of the heavy-load elevator. The sliding structure 43 drives the clamping plate 41 to slide on the lifting seat 32, so that the distance between the two clamping plates 41 matches the width of the PCB circuit board, and the PCB circuit board falls onto the conveyor belt 42; when the PCB circuit board needs to be transported to another opening 2 position with a different height, the driving component 31 drives the lifting seat 32 to slide in the height direction of the shell 1, thereby changing the height of the PCB circuit board, and then the driving structure 44 drives the conveyor belt 42, and the conveyor belt 42 drives the PCB circuit board to approach the opening 2 where the conveyor belt is located, thereby realizing the conveying operation of the PCB circuit board.

Under the action of the support block 434, the rotation of the nut 433 is limited, that is, when the screw rod 431 rotates, the nut 433 will drive the support block 434 to slide in the length direction of the screw rod 431, and the support blocks 434 located at both ends of the screw rod 431 are respectively fixed to a clamping plate 41, and the rotation of the screw rod 431 drives the clamping plate 41 to slide on the base plate 432, thereby realizing the clamping process of the two clamping plates 41.

[0040] Reference Figure 1 and Figure 2 The driving assembly 31 includes a driving member 311 installed on the inner wall of the shell 1 and a support rod 312 fixed to the inner wall of the shell 1. An extension plate is fixed to the inner wall of the shell 1, wherein the driving member 311 is arranged on the extension plate. The driving member 311 is preferably a motor and a rotating rod. One end of the support column 322 is also fixed to the side wall of the extension plate. The driving member 311 and the support column 322 at one end away from the extension plate are fixed to the bottom of the shell 1. There are two support columns 322, which are located on both sides of the driving member 311, and the base 321 is slidably connected to the support column 322. The setting of the support column 322 reduces the possibility of the base 321 rotating on the driving member 311.

[0041] Reference Figure 1 and Figure 3, position sensors 5 are respectively provided at both ends of the clamping plate 41 away from the base 321 along the length direction, and the position sensor 5 is used to detect the relative position of the PCB circuit board on the side wall of the clamping plate 41. When the PCB circuit board slides between the two clamping plates 41, the position sensor 5 detects the position of the PCB circuit board and outputs an electrical signal. Then the heavy-load elevator controls the driving structure 44 and drives the driving assembly 31 and the driving structure 44 to move, thereby realizing the transportation of the PCB circuit board; a number of blocking plates 6 are provided at the position of the opening 2 on the side wall of the shell 1, and a lifting member 7 for controlling the blocking plate 6 is provided on the inner wall of the shell 1.

In the embodiment of the present application, two heat exhaust fans 10 are preferably provided, and the two heat exhaust fans 10 are respectively close to the two support columns 322. The provision of the heat exhaust fan 10 can reduce the internal temperature of the shell 1, reduce heat accumulation, and improve the service life of the heavy-load elevator.

[0043] The implementation principle of a heavy-load elevator in an embodiment of the present application is as follows: when the staff uses the heavy-load elevator, the staff connects the conveyor belt to the opening 2 position of the heavy-load elevator according to the drawing. Before the PCB circuit board is transported to the position of the heavy-load elevator, the driving member 311 controls the base 321 to slide in the height direction of the shell 1, so that the base 321 slides close to the PCB circuit board into the opening 2 position inside the shell 1, and then the PCB circuit board slides into the inside of the shell 1 under the conveying action of the conveyor belt. At this time, the screw rod 431 drives the clamping plate 41 to slide, so that the PCB circuit board falls on the conveying crawler 42. The driving member 311 controls the base 321 to slide on the support column 322 again, so that the base 321 is close to the opening 2 position where the output conveyor belt is located. When the base 321 stops sliding, the driving structure 44 drives the conveying crawler 42 to convey, and the conveying crawler 42 drives the PCB circuit board to slide to the position where the conveyor belt is located. This setting expands the layout of the conveyor belt, thereby facilitating the transportation of PCB circuit boards.
