Description

Technical Field

[0001] This utility model relates to the technical field of guiding devices, specifically to a novel shell-breaking movable frame guiding device. Background Technology

[0002] As a specialized piece of equipment in aluminum electrolysis production, the multi-functional overhead crane is equipped with a shell-breaking machine to perform shell-breaking operations during the aluminum electrolysis process. In aluminum electrolysis, after the electrolyte in the electrolytic cell reacts with the anode, a hard electrolytic shell solidifies around the anode carbon block. To improve electrode switching efficiency, a shell-breaking mechanism is installed on the multi-functional overhead crane unit to strike the electrolytic shell surface.

[0003] The shell-breaking machine relies on a movable frame for movement. The guide wheels, as a crucial component of this frame, serve two main functions. First, they provide guidance. They guide the movable frame along the tracks set on the fixed shell-breaking frame for precise movement. During shell-breaking operations, the movable frame needs to accurately reach designated positions vertically within the electrolytic cell. The guide wheels prevent the frame from deviating from its direction during movement, ensuring accurate shell-breaking positioning. Second, they bear some of the load. The guide wheels distribute the weight of the movable frame and the forces generated during shell-breaking. During the vertical movement of the movable frame, the guide wheels contact the tracks, transferring some of the vertical forces and horizontal frictional forces to the tracks, reducing the load on other components of the movable frame and contributing to the stable operation of the overall structure.

[0004] Due to prolonged use and the presence of foreign objects such as dust and alumina powder in the working environment, the guide wheel assembly of the movable frame is prone to jamming and excessive wear. This leads to a continuous increase in the gap between the movable frame and the fixed frame, reducing the accuracy of movement, causing the movable frame to shake excessively, and the limit sensors to frequently fail to detect or break. The movable frame, which is prone to jamming and excessive wear, not only affects production but also increases the consumption of spare parts, resulting in a high failure rate of the shell-breaking machine.

[0005] Currently, due to the built-in installation of the shell-breaking movable frame wheel set and the space limitations between the fixed frame and the movable frame, it is impossible to replace the wheel set on-site. Replacing the guide wheel set often requires disassembling the entire shell-breaking mechanism and hoisting it to the ground, and then disassembling the entire frame before replacement. The replacement of the guide wheel set is time-consuming, dangerous, and has a significant impact on the normal production of the electrolysis workshop. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a new type of shell-breaking movable frame guide device, which includes a movable frame, a vertical guide assembly and a horizontal guide assembly. This new type of shell-breaking movable frame guide device has the advantages of short replacement time of guide wheel assembly, low operational risk and minimal impact on normal production in the electrolysis workshop.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0008] A novel shell-breaking movable frame guiding device includes a movable frame, a vertical guide assembly, and a horizontal guide assembly. Both the vertical guide assembly and the horizontal guide assembly are mounted on the movable frame. The vertical guide assembly includes a support base, a support column, a rotating sleeve, and a vertical guide wheel. The movable frame has mounting holes, the support base is mounted within the mounting holes, the support column is fixedly mounted on the support base, the rotating sleeve is rotatably connected to the support column, and the vertical guide wheel is mounted on the rotating sleeve. The vertical guide wheel is located inside the movable frame, and its diameter is smaller than the diameter of the mounting hole.

[0009] This setup allows the vertical guide wheels, which are installed inside the movable frame, to be removed to the outside of the movable frame. This facilitates the maintenance of the vertical guide assembly, and the movable frame does not need to be removed when repairing the vertical guide assembly. The replacement of the guide wheel assembly is quick, has low operational risk, and has minimal impact on the normal production of the electrolysis workshop.

[0010] Preferably, the support base is fixedly connected to a support plate, and the support plate is provided with a fixing member that is threadedly connected to the movable frame.

[0011] This setup keeps the support fixed on the movable frame.

[0012] Preferably, the support plate has a positioning plane on its edge, and the movable frame is fixedly connected to a card plate that fits with the positioning plane.

[0013] This design improves the stability of the support and reduces the shear force on the fasteners.

[0014] Preferably, the support plate is provided with tooth holes.

[0015] This design adds a point of leverage to the support plate, making it easier to pull the support plate and support base outwards from the movable frame.

[0016] Preferably, the support column has an oil inlet hole at one end near the outer side of the movable frame, and the side wall of the support column has an oil delivery hole that connects to the inner wall of the rotating sleeve. The oil inlet hole and the oil delivery hole are connected.

[0017] This design facilitates lubrication of the vertical guide components.

[0018] Preferably, the transverse guide assembly includes a threaded sleeve, a threaded tube, a guide seat, a transverse guide wheel, and a bolt. The threaded tube is fixedly mounted on the movable frame, passes through the threaded sleeve, and is threadedly connected to the threaded sleeve. The bolt passes through the threaded tube. The guide seat is located inside the movable frame, and the bolt is threadedly connected to the guide frame. The transverse guide wheel is rotatably mounted on the guide seat.

[0019] This setup allows for the installation of the lateral guide components onto the movable frame.

[0020] Preferably, the threaded tube extends outside the movable frame.

[0021] This design makes it easier to turn the bolts.

[0022] Preferably, the threaded pipe connection has a locking nut that engages with the threaded sleeve.

[0023] This configuration improves the stability between the threaded pipe and the threaded sleeve.

[0024] Preferably, the movable frame is fixedly connected to a positioning plate that engages with the guide seat.

[0025] This design serves to prevent bolt breakage and allows for the positioning of the movable frame.

[0026] Preferably, multiple mounting holes, vertical guide components, and lateral guide components are provided, and the multiple mounting holes, vertical guide components, and lateral guide components correspond one-to-one.

[0027] This design improves the stability of the movable frame during movement.

[0028] Compared with the prior art, this utility model has achieved beneficial technical effects:

[0029] When maintenance of the vertical guide assembly is required, the fixing component is rotated to remove it from the movable frame and support plate. Then, the fixing component is screwed into the threaded hole, and the fixing component is pulled outward from the movable frame. This causes the support plate, support base, and support column to move outward from the movable frame, thereby moving the vertical guide wheel through the mounting hole to the outside of the movable frame. This allows the vertical guide wheel, which is installed inside the movable frame, to be removed to the outside of the movable frame. This facilitates the maintenance of the vertical guide assembly, and the movable frame does not need to be removed when maintaining the vertical guide assembly. The replacement of the guide wheel assembly is quick, has low operational risk, and has minimal impact on the normal production of the electrolysis workshop. Attached Figure Description

[0036] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0037] refer to Figure 1-4 A novel shell-breaking movable frame 11 guide device includes a movable frame 11, a vertical guide component 20, and a horizontal guide component 30.

[0038] Both the vertical guide assembly 20 and the horizontal guide assembly 30 are mounted on the movable frame 11. The vertical guide assembly 20 includes a support base 21, a support column 22, a rotating sleeve 25, and a vertical guide wheel 26. The movable frame 11 has a mounting hole 12, in which the support base 21 is installed. The support column 22 is fixedly installed on the support base 21, and the rotating sleeve 25 is rotatably connected to the support column 22. The vertical guide wheel 26 is installed on the rotating sleeve 25 and is located inside the movable frame 11. The diameter of the vertical guide wheel 26 is smaller than the diameter of the mounting hole 12. A support plate 27 is fixedly connected to the support base 21, and a fastener 28, which is threadedly connected to the movable frame 11, passes through the support plate 27. The fastener 28 fixes the support plate 27 to the movable frame 11, thereby keeping the support base 21 fixed on the movable frame 11. A positioning plane 13 is provided on the edge of the support plate 27, and a clamping plate 14 that fits against the positioning plane 13 is fixedly connected to the movable frame 11. The support plate 27 is secured by the clamping plate 14 to prevent the support plate 27 and the support base 21 from rotating on the movable frame 11, thereby improving the stability of the support base 21 and reducing the shear force on the fixing member 28. The support plate 27 is provided with a threaded hole 29. The removed fixing member 28 is screwed into the threaded hole 29 to connect the fixing member 28 to the support plate 27, thereby pulling the fixing member 28 outward from the movable frame 11 and moving the support plate 27 outward from the movable frame 11. This increases the force point on the support plate 27, making it easier to pull the support plate 27 and the support base 21 outward from the movable frame 11. The support column 22 has an oil inlet hole 23 at one end near the outside of the movable frame 11, and an oil delivery hole 24 on the side wall of the support column 22 that connects to the inner wall of the rotating sleeve 25. The oil inlet hole 23 and the oil delivery hole 24 are connected. Lubricating oil is injected into the oil inlet 23, and the lubricating oil flows through the oil delivery hole 24 to the inner wall of the rotating sleeve 25, thereby lubricating the inner wall of the rotating sleeve 25 and facilitating the lubrication of the vertical guide assembly 20.

[0039] The transverse guide assembly 30 includes a threaded sleeve 31, a threaded tube 32, a guide seat 33, a transverse guide wheel 34, and a bolt 35. The threaded tube 32 is fixedly mounted on the movable frame 11, passing through the threaded sleeve 31 and threadedly connected to it. The bolt 35 passes through the threaded tube 32. The guide seat 33 is located inside the movable frame 11, and the bolt 35 is threadedly connected to it. The transverse guide wheel 34 is rotatably mounted on the guide seat 33. This allows the transverse guide assembly 30 to be installed onto the movable frame 11. The threaded tube 32 extends outward from the movable frame 11. The bolt 35 has a bolt head that engages with the threaded tube 32. The threaded tube 32 extends outward from the movable frame 11, allowing the bolt head to be turned at a distance from the movable frame 11, preventing it from being jammed by the movable frame 11 during turning and facilitating the turning of the bolt head. The threaded tube 32 is threadedly connected to a locking nut 36 that engages with the threaded sleeve 31. By tightening the locking nut 36, the locking nut 36 is pressed against the threaded sleeve 31 and a preload is applied to the threaded tube 32, thereby maintaining the self-locking of the threaded sleeve 31, the threaded tube 32, and the locking nut 36, improving the stability between the threaded tube 32 and the threaded sleeve 31. The movable frame 11 is fixedly connected to a positioning plate 15 that engages with the guide seat 33. By locking the movable frame 11 with the positioning plate 14, the shear force applied to the bolt 35 during vibration of the movable frame 11 can be reduced, preventing the bolt 35 from breaking. The positioning plate 15 can position the movable frame 11.

[0040] Multiple mounting holes 12, vertical guide components 20, and horizontal guide components 30 are provided, with each of these components corresponding to the other. These multiple vertical guide components 20 and horizontal guide components 30 can guide the movable frame 11 at different positions within the shell-fixing frame, thereby improving the stability of the movable frame 11 during movement.

[0041] The vertical guide wheel 26 and the horizontal guide wheel 34 are used to contact the shell-breaking fixing frame. The vertical guide wheel 26 and the horizontal guide wheel 34 are placed at perpendicular angles, so that the vertical guide wheel 26 and the horizontal guide wheel 34 can provide support in different directions respectively.

[0042] This embodiment has the following advantages:

[0043] When maintenance of the vertical guide assembly 20 is required, the fixing member 28 is rotated to remove it from the movable frame 11 and the support plate 27. Then, the fixing member 28 is screwed into the threaded hole 29, and then the fixing member 28 is pulled outward from the movable frame 11. This causes the support plate 27, support seat 21, and support column 22 to move outward from the movable frame 11, thereby moving the vertical guide wheel 26 through the mounting hole 12 to the outside of the movable frame 11. This allows the vertical guide wheel 26, which is installed inside the movable frame 11, to be removed to the outside of the movable frame 11. This facilitates maintenance of the vertical guide assembly 20, and the movable frame 11 does not need to be removed when maintaining the vertical guide assembly 20. The replacement of the guide wheel assembly is quick, has low operational risk, and has minimal impact on the normal production of the electrolysis workshop.
