Description

Technical Field

[0001] This utility model relates to the field of cylinder auxiliary tooling technology, specifically to a flip-top type cylinder fixing base. Background Technology

[0002] In electrolytic aluminum production workshops, cylinders are usually fixedly installed above the electrolytic cells. Their function is to drive the opening and closing of the cell cover during the electrolytic aluminum production process.

[0003] Currently, the installation and fixing of cylinders typically involves using two screws to fix the fixed shaft at the bottom of the cylinder on both sides. This fixing method provides good stability and ensures the cylinder's stable operation. However, since the electrolytic cell needs to operate continuously, cylinder maintenance usually has to be carried out without shutting down the electrolytic cell. Because the temperature above the cell is high during operation, maintenance personnel need to perform cylinder maintenance in a high-temperature environment. The existing cylinder installation method requires the simultaneous removal of both screws during disassembly and assembly, which is cumbersome and time-consuming. If cylinder disassembly and assembly maintenance is performed under these conditions, the operators will be exposed to high temperatures for extended periods, posing a risk of heatstroke and a high safety hazard. Utility Model Content

[0004] The present invention aims to provide a flip-top type cylinder fixing base to solve the problems of existing cylinder fixing methods, which are cumbersome to operate during maintenance, time-consuming to operate, and cause operators to be exposed to high temperature environment for a long time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flip-top type cylinder fixing base, including a support, a flip-top hinged to one end of the support, a first mounting hole provided at the end of the flip-top away from the hinge, a second mounting hole provided on the support that is directly opposite the first mounting hole, a screw inserted into the first mounting hole and the second mounting hole, the end of the flip-top away from the hinge being detachably fixed to the support by the screw, the end of the screw being locked by a nut, the flip-top having an upwardly arched upper arc portion, the support having a downwardly recessed lower arc portion, the upper arc portion and the lower arc portion forming a fixing hole through which the cylinder bottom fixing shaft can pass.

[0006] The principle and advantages of this solution are as follows: by designing the fixed base as a flip-top structure, the original two screws used for connection and fixation are replaced with only one screw for fixation. In this way, during disassembly and maintenance, only one screw needs to be removed, and the bottom fixed shaft of the cylinder can be taken out from the fixed hole to complete the disassembly and assembly of the cylinder. This enables quick disassembly and assembly of the cylinder, shortens the exposure time of operators in high-temperature environments, and greatly reduces safety hazards.

[0007] Preferably, as an improvement, the screw is provided with a through hole that runs radially through the screw; the support is also provided with a third mounting hole and a fourth mounting hole that are perpendicular to and connected to the second mounting hole, the third mounting hole and the fourth mounting hole are located on the same horizontal line, and a locking pin is inserted into the third mounting hole, the locking pin passing through both the through hole and the fourth mounting hole.

[0008] With the above solution, the locking pin can lock the screw radially, preventing the screw from coming out of the second mounting hole, ensuring the screw is effectively fixed to the flip cover and the support, and thus ensuring the base is effectively fixed to the cylinder.

[0009] Preferably, as an improvement, the end of the support that is hinged to the flip cover is connected by a pin, and the end of the pin is provided with a cotter pin.

[0010] The above solution, using a pin for hinge, allows for greater freedom of movement when the cover is flipped, and facilitates the assembly and disassembly of the cylinder. The cotter pin limits the pin's position, preventing it from dislodging and ensuring a stable connection between the cover and the support.

[0011] Preferably, as an improvement, the end of the locking pin is also provided with a cotter pin.

[0012] The above solution allows the cotter pin to limit the locking pin, preventing it from coming out and ensuring that the screw stably connects the flip cover and the support.

[0013] Preferably, as an improvement, a washer is provided between the nut and the flip cover surface.

[0014] Through the above solution, the washer prevents the nut from loosening and ensures that the screw effectively connects and fixes the flip cover and the support.

[0015] Preferably, as an improvement, the gasket is a flat gasket or a flexible gasket.

[0016] The above methods can effectively prevent loosening. Attached Figure Description

[0021] The flip-top cylinder fixing base includes a support 1, one end of which is hinged to a flip cover 2. The end of the support 1 and the flip cover 2 are hinged together by a pin 3, and the end of the pin 3 is provided with a cotter pin 4.

[0022] Combination Figure 2 As shown, the end of the flip cover 2 away from the hinge is provided with a first mounting hole 5, and the support 1 is provided with a second mounting hole 6 that is directly opposite to the first mounting hole 5. A screw 7 is inserted into the first mounting hole 5 and the second mounting hole 6. The end of the flip cover 2 away from the hinge is detachably fixed to the support 1 by the screw 7. The end of the screw 7 is locked by a nut 8. A washer 9 is provided between the nut 8 and the surface of the flip cover 2. The washer 9 is a flat washer and an elastic washer. The screw 7 is provided with a through hole 10 that runs radially through the screw 7. The support 1 is also provided with a third mounting hole 11 and a fourth mounting hole 12 that are perpendicular to and connected to the second mounting hole 6. The third mounting hole 11 and the fourth mounting hole 12 are located on the same horizontal line. A locking pin 13 is inserted into the third mounting hole 11. The locking pin 13 passes through both the through hole 10 and the fourth mounting hole 12. The end of the locking pin 13 is also provided with a cotter pin 4.

[0023] The flip cover 2 has an upwardly arched upper arc portion 14, and the support 1 has a downwardly recessed lower arc portion 15. The upper arc portion 14 and the lower arc portion 15 together form a fixing hole 16 through which the cylinder bottom fixing shaft can pass.

[0024] In this embodiment, the support 1 is fixed to an external mounting bracket. The flip cover 2 is opened, and the fixed shaft at the bottom of the cylinder is placed into the lower arc portion 15. The flip cover 2 is then closed, so that the upper arc portion 14 covers the fixed shaft at the bottom of the cylinder.
