Description

Technical Field

[0001] This utility model belongs to the field of elevators, specifically relating to an upper elevator for an electrolytic cell. Background Technology

[0002] The spiral elevator on the upper part of the electrolytic cell is a significant hazard source, making routine equipment inspections crucial. Recently, the elevator's expansion joint has frequently experienced sparking. On-site investigation revealed that damage to the O-ring seal on the elevator body caused the expansion cylinder to slide down, resulting in direct connection between the expansion joint and the elevator hanger. This compromised insulation, leading to sparking and damage to the elevator, posing a significant safety hazard to the electrolytic cell. Replacing the seal requires replacing the entire elevator, making maintenance cumbersome and potentially affecting the operational stability of the electrolytic cell. Therefore, this invention proposes an upper elevator for the electrolytic cell to address the problems existing in the prior art. Utility Model Content

An internal groove is opened on the inner wall of the insulating hose. A buffer spring is installed in the internal groove. Several sets of iron wires are equidistantly distributed on the inner wall of the insulating hose. An upper opening is opened through the upper end of the insulating hose, and a lower opening is opened through the lower end of the insulating hose.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please see Figures 1-7 This utility model provides an embodiment of an electrolytic cell upper hoist, including a hoist body 3 and a hoist frame 1, and further including an insulating hose 5, a movable sleeve 10, and a fixed sleeve 14. A rotating shaft 2 is rotatably mounted on the inner wall of the hoist frame 1, and an extension shaft 7 is fixedly connected to the center of the outer wall of the rotating shaft 2. A hoist telescopic joint 4 is installed at the lower end of the hoist body 3. The upper and lower ends of the insulating hose 5 are respectively fixedly connected to the fixed sleeve 14 and the movable sleeve 10, and the lower end of the movable sleeve 10 is fixedly connected to a movable ring 11. The outer wall of the ring 11 is provided with several sets of mounting grooves 12 that are equidistantly distributed around the outer wall of the movable ring 11. A pulley 13 is rotatably installed in the mounting groove 12. The outer wall of the insulating hose 5 is provided with several sets of corrugated grooves 9 that are equidistantly distributed. The inner wall of the insulating hose 5 is provided with an inner groove 18. A buffer spring 17 is installed in the inner groove 18. Several sets of iron wires 8 are equidistantly distributed on the inner wall of the insulating hose 5. The upper end of the insulating hose 5 is provided with an upper opening 15, and the lower end of the insulating hose 5 is provided with a lower opening 16.

[0016] By embedding equidistantly distributed iron wires 8 into the inner wall of the insulating hose 5, a longitudinal structural support is formed to prevent the hose from collapsing or deforming under expansion or high temperature conditions, ensuring the long-term stability of the insulation structure. The outer wall of the insulating hose 5 has equidistant corrugated grooves 9, which give the hose a certain degree of elasticity and can deform synchronously with the up and down movement of the hoist telescopic joint 4, avoiding structural damage caused by rigid tension. The inner wall of the insulating hose 5 has an internal groove 18 and is equipped with a buffer spring 17. When the telescopic joint expands and contracts rapidly, the spring can absorb the impact energy and reduce hard collisions between components. The three work together to protect the insulating hose 5 while improving the stability of the hoist's operation, ensuring that the device can still function stably under dynamic working conditions.

[0017] Please see Figures 3-4 In this embodiment, the insulating hose 5 is fitted onto the outer wall of the hoist telescopic joint 4, the fixed sleeve 14 is installed on the outer wall of the hoist telescopic joint 4, and the movable sleeve 10 is disposed on the outer wall of the extension shaft 7. The fixed sleeve 14 is installed on the outer wall of the telescopic joint to reinforce the fixed end of the telescopic joint and prevent it from displacing or shaking during operation. The movable sleeve 10 is disposed on the outer wall of the extension shaft 7 and can adapt to the movement characteristics of the extension shaft 7. It does not hinder the extension or rotation of the shaft and can also play a limiting and protective role.

[0018] Please see Figures 4-5In this embodiment, the lower end of the hoist telescopic joint 4 is connected to the extension shaft 7. The front and rear ends of the rotating shaft 2 are connected to the front and rear ends of the hoist hanger 1 and the outer wall of the shaft is fitted with a limit ring 6. The lower end of the hoist telescopic joint 4 is connected to the extension shaft 7, which can realize the continuous transmission of telescopic and extension, reduce the transmission gap between components, and improve the power transmission efficiency.

[0019] Please see Figures 4-7 In this embodiment, the inner wall of the upper opening 15 is fitted with the outer wall of the hoist telescopic joint 4, and the inner wall of the lower opening 16 is fitted with the outer wall of the extension shaft 7. The inner wall of the upper opening 15 fits against the outer wall of the telescopic joint, and the inner wall of the lower opening 16 fits against the outer wall of the extension shaft 7, forming a double-fit seal. This effectively prevents dust, impurities, or liquids from entering the internal structure, reducing the risk of corrosion and jamming of internal components. The movable ring 11 is disposed on the outer wall of the extension shaft 7, and the outer wall of the pulley 13 fits against the outer wall of the extension shaft 7. This fits the outer wall of the pulley 13 against the outer wall of the extension shaft 7, converting the sliding friction of the extension shaft 7 into rolling friction, significantly reducing the frictional resistance between the two and reducing component wear. To ensure smoother extension and retraction of the extension shaft 7, the opening area of ​​the upper opening 15 is larger than that of the lower opening 16, and the opening area of ​​the movable sleeve 10 is larger than that of the fixed sleeve 14. The upper opening 15 is larger than the lower opening 16, which can accommodate common structures where the diameter of the telescopic joint is larger than that of the extension shaft 7. This ensures that the upper and lower openings 16 can accurately correspond to components of different diameters, avoiding sealing failure or jamming due to size mismatch. The insulating hose 5 is elliptical, and several sets of iron wires 8 are distributed from large to small and from top to bottom along the inner wall of the insulating hose 5. The elliptical shape of the insulating hose 5 is better able to fit the outer wall of the non-circular telescopic joint than a circle, improving the sealing performance and saving installation space.

[0020] When in use, first put the insulating hose 5 on the outer wall of the hoist telescopic joint 4. The upper end is fixed to the hoist telescopic joint 4 through the fixed joint sleeve 14, and the lower end is put on the outer wall of the extension shaft 7 through the movable joint sleeve 10. The pulley 13 in the movable ring 11 is in contact with the outer wall of the extension shaft 7. When the hoist is working, the hoist telescopic joint 4 extends and retracts vertically, and the insulating hose 5 deforms with the extension and retraction. The corrugated groove 9 on its outer wall can adapt to the extension and retraction range, the buffer spring 17 on the inner wall can relieve the impact force during extension and retraction, and the wire 8 ensures that the insulating hose 5 does not collapse during deformation. At the same time, the insulating hose 5 completely wraps the connection between the hoist telescopic joint 4 and the extension shaft 7. The upper opening 15 fits against the outer wall of the telescopic joint, and the lower opening 16 fits against the outer wall of the extension shaft 7, forming a complete insulation barrier to prevent the two from directly contacting the hoist frame 1 and damaging the insulation.

[0021] Through the above steps, the insulating hose 5 is double-fixed by the fixed sleeve 14 and the movable sleeve 10, and the inner wall iron wire 8 enhances the structural strength, ensuring the stability of the hoist during online operation and avoiding operational failures caused by loose parts. The outer wall corrugated groove 9 adapts to the extension range, and the inner wall buffer spring 17 relieves the impact, adapting to the dynamic operation of the hoist and solving the problem of easy damage to the sealing ring of the existing hoist extension joint 4.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
