Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] This embodiment installs the clamping device on the overhead crane, and can connect the crane's hoisting mechanism and the supporting main rod of the clamping device through a connecting rod. The supporting main rod is provided with two symmetrically arranged clamping plates, which can clamp the cathode plate as needed. At the same time, the two clamping plates are respectively controlled by two adjustment components, so that under the action of the linear motor, the clamping range and clamping force of the clamping plates can be quickly and automatically adjusted, which can ensure that the cathode plate is firmly fixed during the clamping process and is not likely to fall. This improves the clamping effect when the cathode plate of the electrolytic cell is hoisted and transported, and further improves the practicality and safety of the clamping device. The specific implementation is as follows:

[0031] like Figures 1 to 4As shown, a clamping device for lifting the cathode of an electrolytic cell includes a supporting main rod 1, a connecting rod 2, a splint 4 and an adjusting assembly 5. The connecting rod 2 is connected to the middle of the upper surface of the supporting main rod 1, and relatively movable splints 4 are symmetrically arranged on both sides of the lower surface of the supporting main rod 1. The two splints 4 are slidably connected to the adjusting track 8 formed on the top of the supporting main rod 1 through two adjusting assemblies 5 respectively. The adjusting assembly 5 includes a sliding plate 10, a linear motor 11 and a guide rod 12. A guide rod 12 is provided above the supporting main rod 1. The guide rod 12 is connected to the linear motor 11 and can move along the length direction of the guide rod 12. The linear motor 11 is installed on the sliding plate 10, and the sliding plate 10 is slidably connected to the adjusting rail 8. A connecting channel 9 is formed in the middle of the adjusting rail 8, and the splint 4 is connected to the sliding plate 10 through the connecting channel 9. The clamping device is installed on the overhead crane, and the lifting mechanism of the overhead crane and the supporting main rod 1 of the clamping device can be connected through the connecting rod 2. The supporting main rod 1 is provided with two symmetrically arranged clamping plates 4, which can clamp the cathode plate as needed. At the same time, the two clamping plates 4 are respectively controlled by two adjustment components 5, so that under the action of the linear motor 11, the clamping range and clamping force of the clamping plates 4 can be quickly and automatically adjusted, which can ensure that the cathode plate is firmly fixed during the clamping process, making it less likely to fall, thereby improving the clamping effect during the lifting and transportation of the cathode plate of the electrolytic cell, and further improving the practicality and safety of the clamping device.

[0032] The bottom of the sliding plate 10 is provided with a connecting seat 19 which penetrates the connecting channel 9. The bottom of the connecting seat 19 is connected to the clamping plate 4. The connecting seat 19 facilitates the connection between the sliding plate 10 and the clamping plate 4 and allows the position to be limited in the connecting channel 9, thereby improving the overall stability.

[0033] Side sliders 13 are mounted on either side of the connecting seat 19. Side sliding tracks 16 are formed on either side of the connecting channel 9 along the length of the supporting main rod 1, matching the two side sliders 13. The connecting seat 19 is slidably connected to the side sliding tracks 16 via the two side sliders 13, thereby improving the support capacity of the sliding plate 10 on the clamping plate 4 and allowing it to move along the side sliding tracks 16 for improved adjustment.

[0034] The two clamping plates 4 are provided with an anti-skid layer 14 on one side thereof, and the anti-skid layer 14 is composed of a plurality of anti-skid protrusions. The anti-skid layer 14 can improve the friction force when the clamping plates 4 clamp the cathode plate, prevent the cathode plate from sliding, and improve the clamping stability.

[0035] Pressure sensors 15 are provided inside the two clamping plates 4, and an alarm 7 connected to the two pressure sensors 15 is installed in the middle of the front of the connecting rod 2. The pressure sensors 15 provided inside the clamping plates 4 can monitor the squeezing force applied to the cathode plate during the clamping process to prevent damage to the cathode plate caused by excessive squeezing. In the event of abnormal pressure, the alarm 7 can also sound an alarm to facilitate timely handling by staff. The alarm 7 is electrically connected to the two pressure sensors 15.

[0036] A display 6 is mounted in the middle of the front of the connecting rod 2, and the display 6 is electrically connected to the two pressure sensors 15. The display 6 can display the pressure data of the extrusion force generated on the cathode plate during the clamping process, thereby facilitating viewing and management.

[0037] A lifting ring 3 is installed on the top of the connecting rod 2. Through the lifting ring 3, it is convenient to connect the overhead crane lifting equipment

[0038] A reinforcement plate 17 is provided on the outside of the support main rod 1, and a pressure plate 18 is provided on the inner wall of the connecting channel 9 on the support main rod 1. The reinforcement plate 17 provided on the outside of the support main rod 1 and the pressure plate 18 provided on the inside of the support main rod 1 can improve the overall strength of the support main rod 1, making it have good pressure resistance both inside and outside, and facilitating the connection and support of the support main rod 1 with the adjustment assembly 5 and the clamping plate 4.

[0039] The material of the supporting main rod 1 and the splint 4 is stainless steel.

[0040] The bottom of connecting seat 19 is provided with mounting plate, is formed with several threaded mounting holes on the mounting plate and can be threadedly connected with clamping plate 4. By the provision of mounting plate and threaded mounting holes, can be convenient to the disassembly and replacement of clamping plate 4.

[0041] Working principle: The clamping device is installed on the overhead crane, and the lifting mechanism of the overhead crane and the supporting main rod of the clamping device can be connected through a connecting rod. The supporting main rod is provided with two symmetrically arranged clamping plates, which can clamp the cathode plate as needed. At the same time, the two clamping plates are controlled by two adjustment components respectively, so that under the action of the linear motor, the clamping range and clamping force of the clamping plates can be quickly and automatically adjusted, which can ensure that the cathode plate is firmly fixed during the clamping process, making it less likely to fall, improving the clamping effect during the lifting and transportation of the cathode plate of the electrolytic cell, and further improving the practicality and safety of the clamping device. The pressure sensor arranged inside the clamping plate can monitor the extrusion pressure generated on the cathode plate during the clamping process to avoid damage to the cathode plate caused by excessive extrusion. When the pressure is abnormal, an alarm can be issued through the alarm to facilitate timely handling by the staff. The reinforcing plate arranged on the outside of the supporting main rod and the pressure-bearing plate inside the supporting main rod can improve the overall strength of the supporting main rod, so that it has good pressure resistance both inside and outside, which facilitates the connection and support of the supporting main rod with the adjustment component and the clamping plate.
