Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum machinery and equipment, and more specifically, to a device for disassembling small box clamps to prevent them from detaching. Background Technology

[0002] The small box clamp is a key equipment component in aluminum electrolysis production. It mainly fixes the anode guide rod to the busbar. During the aluminum electrolysis process, as the reaction proceeds, the anode guide rod needs to be replaced regularly. In the process of replacing the anode guide rod, the small box clamp needs to be disassembled and installed. However, the small box clamp is worn or deformed during long-term use. In addition, the inertia and vibration of the overhead crane robotic arm during operation cause the small box clamp to frequently become detached and fall during operation.

[0003] Utility model patent CN219136959U discloses a device for preventing small box clamps from falling and a pole-changing crane. The device for preventing small box clamps from falling includes an anti-disengagement hook. The first end of the anti-disengagement hook is rotatably connected to the main body of the pole-changing crane. The second end of the anti-disengagement hook slides into contact with the hook seat when the pole-changing crane main body approaches the hook seat for supporting the clamping shaft from top to bottom, and can rotate away from the pole-changing crane main body under the pushing action of the hook seat. After the pole-changing crane main body carrying the small box clamps is separated from the hook seat, the second end of the anti-disengagement hook can move under the action of gravity to below the clamping shaft, and the anti-disengagement component can support the clamping shaft. This utility model uses a "J"-shaped anti-disengagement hook to prevent the small box clamps from falling. However, due to the inertial swaying during the movement of the crane, the small box clamps are very prone to disengagement and falling when encountering excessive swaying. Utility Model Content

[0004] This invention addresses the problem of small box clamps easily detaching and falling during the replacement of anode guide rods by providing a small box clamp disassembly device to prevent detachment.

[0005] The technical solution adopted in this utility model is:

[0006] A device for removing a small box clamp that prevents disengagement includes a base, a wrench mechanism mounted on the base, and an anti-disengagement mechanism mounted on the wrench mechanism. The anti-disengagement mechanism is installed below the wrench mechanism and includes an anti-disengagement hook one and an anti-disengagement hook two, which are symmetrically arranged directly above the clamping shaft of the small box clamp. The anti-disengagement hook one and the anti-disengagement hook two are connected by a connector. The anti-disengagement hook one and the anti-disengagement hook two include two anti-disengagement plates, which are rotatably connected to the wrench mechanism. One end of the two anti-disengagement plates is connected by a spring, and the other end is used to clamp the small box clamp.

[0007] Furthermore, a pressure plate is provided at one end of the anti-disengagement plate spring connection, and the spring is installed between the pressure plates through a pin in the compressed state.

[0008] Furthermore, the anti-disengagement mechanism is also equipped with a shock-absorbing spring, which abuts against a limiting baffle plate provided on the base.

[0009] Furthermore, the end of the anti-detachment plate that connects to the small box clamp is set in an arc shape.

[0010] Furthermore, a guide shaft is rotatably mounted on the wrench mechanism.

[0011] Furthermore, the outer periphery of the guide shaft is wrapped with an elastic buffer layer.

[0012] Furthermore, the wrench mechanism includes a torque sleeve and a drive component for driving the torque sleeve.

[0013] Furthermore, the torque sleeve is fixedly installed below the base, with the sleeve facing the small box clamp fixing screw; the drive component is fixedly installed on the base and connected to the torque sleeve through a gear shaft.

[0014] Furthermore, the driving component is a servo motor.

[0015] Furthermore, the base is fixedly connected to the overhead crane's robotic arm.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model provides a small box clamp disassembly device that prevents detachment. By setting an anti-detachment device to clamp the small box clamp, when the entire device reaches above the clamping shaft of the small box clamp, the clamping shaft is clamped into the buckle formed by two anti-detachment plates by gravity. A spring is set between the two anti-detachment plates, and the elastic force generates an inward restraining force to prevent the two anti-detachment plates from opening outward and causing the small box clamp to fall off. The device has a simple structure, is highly practical, and can effectively prevent the small box clamp from detaching and falling off during the replacement operation. Attached Figure Description

[0027] A device for removing a small box clamp that prevents detachment, used for removing small box clamps, wherein the small box clamp is as follows: Figure 5 As shown, the device includes a clamping shaft 8 hanging on a fixed base and a fixing screw 9 for fixing the small box clamp. The anti-disengagement small box clamp disassembly device includes a base 1, a wrench mechanism 2 mounted on the base 1, and an anti-disengagement mechanism set on the wrench mechanism. Multiple connecting bolts 5 are provided above the base 1, and the connecting bolts 5 are fixedly connected to the overhead crane robotic arm. The overhead crane robotic arm controls the movement of the overall disassembly device. The anti-disengagement mechanism is installed below the wrench mechanism and includes anti-disengagement hook one 3 and anti-disengagement hook two 4. The two are symmetrically arranged directly above the clamping shaft 8 of the small box clamp. Anti-disengagement hook one 3 and anti-disengagement hook two 4 are connected by a connector 7. Anti-disengagement hook one 3 and anti-disengagement hook two 4 include two anti-disengagement plates 31. The two anti-disengagement plates 31 are hinged to the wrench mechanism 2. One end of the two anti-disengagement plates 31 is connected by a spring 33, and the other end is used to clamp the small box clamp.

[0028] Specifically, one end of the anti-disengagement plate 31 connected to the spring is provided with a pressure plate 32. The spring 33 is installed between the pressure plates 32 through the pin 34 in the compressed state. The spring 33 is made of high-carbon steel with high elasticity and high tensile strength. After the clamping shaft 8 is inserted between the anti-disengagement plates 31, the spring force restricts the anti-disengagement plates 31 from opening. The end of the anti-disengagement plate 31 connected to the small box clamp is set to be arc-shaped. After the clamping shaft 8 contacts the arc-shaped contact edge, the arc shape is equivalent to a guide rail and can optimize the mechanical distribution, making the anti-disengagement mechanism more smooth when it is inserted.

[0029] The wrench mechanism 2 includes a torque sleeve 22 and a drive component 21 for driving the torque sleeve. The torque sleeve 22 is fixedly installed below the base 1, with the sleeve 22 facing the small box clamp fixing screw 9. The drive component 21 is fixedly installed on the base 1 and connected to the torque sleeve 22 through a gear shaft. The drive component 21 is a servo motor.

[0030] When replacing the anode guide rod, the base 1 is rigidly connected to the overhead crane robotic arm. The overhead crane robotic arm controls the disassembly device to move directly above the small box clamp, aligning the anti-disengagement mechanism with the clamping shaft 8. The overhead crane robotic arm continues to move downward, and under the action of external force, the clamping shaft 8 is clamped into the anti-disengagement mechanism. After clamping, the spring 33 restricts the anti-disengagement plate 31 from opening, preventing the small box clamp from falling. At the same time, the torque sleeve 22 is connected to the fixing screw 9, and the servo motor starts to loosen the fixing screw 9, completing the disassembly of the small box clamp.
