Description

Technical Field

[0001] This utility model relates to the field of horizontal equipment head opening technology, and in particular to a small-space 90-degree rotating boom for opening horizontal equipment heads. Background Technology

[0002] Horizontal tank equipment is widely used in industries such as chemical, energy, and water treatment. Routine inspections, internal maintenance, and material cleaning of this equipment all require frequent opening of the end caps. Traditionally, the end caps of horizontal equipment are mostly disassembled and opened using conventional lifting equipment such as split-type lifting tools, hand-operated hoists, and overhead cranes. This not only requires a large operating space for the lifting tools to swing, the end caps to move and rotate, but also necessitates completing multiple steps of lifting, moving, and rotating, making the operation cumbersome and time-consuming.

[0003] Currently, many production sites suffer from limited space around tanks due to factory layout and equipment arrangement, making it impossible for conventional lifting equipment and split-type lifting devices to operate normally. Forced operation can easily lead to safety hazards such as head collisions and unstable lifting. Therefore, there is an urgent need for a horizontal equipment head opening system with a small-space 90-degree rotating boom to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small-space 90-degree rotating boom for opening the end caps of horizontal equipment. Its advantages include: simultaneous horizontal movement of the end cap body and 90-degree rotation for opening, eliminating the need for additional operating steps and significantly improving the efficiency of end cap opening; and the entire process can be completed in a small space, effectively solving the problem of inconvenient operation of traditional equipment in confined spaces, making it particularly suitable for space-constrained work scenarios and enhancing the applicability of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A 90-degree rotating boom for opening the end cap of a horizontal equipment includes a mounting base fixedly connected to the outer circumference of the tank body. A connecting column is provided on one side of the mounting base. A horizontal column is fixedly connected to one end of the connecting column. A limiting plate is fixedly connected to one end of the horizontal column. A threaded column is fixedly connected to one side of the outer wall of the limiting plate. The threaded column passes through the center of a lifting lug fixedly connected to one side of the outer wall of the end cap body. A nut is threadedly connected to the outer circumference of the threaded column. One side of the mounting base is provided with a transverse moving component for driving the end cap body to move horizontally; A rotating assembly is provided above the mounting base for rotating and opening the end cap body during horizontal movement.

[0006] The above technical solution enables the simultaneous horizontal movement and 90-degree rotation of the end cap body, eliminating the need for additional operating steps and significantly improving the efficiency of end cap opening. Furthermore, the entire process can be completed in a small space, effectively solving the problem of inconvenient operation of traditional equipment in confined spaces. It is particularly suitable for space-constrained work scenarios, enhancing the applicability of the equipment.

[0007] Preferably, the transverse component includes a motor fixedly connected to the outer wall of one side of the mounting base, a threaded screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the outer circumference of the threaded screw, a bent column fixedly connected to the top outer wall of the threaded sleeve, a support plate fixedly connected to one end of the bent column, the support plate fixedly connected to the mounting base, and the end of the connecting column away from the transverse column rotatably connected to the support plate.

[0008] The above technical solutions can stably and reliably drive the head body to complete the horizontal displacement.

[0009] Preferably, a guide post is fixedly connected inside the mounting base, and a guide block is sleeved on the outer circumference of the guide post, and the guide block is fixedly connected to the threaded sleeve.

[0010] The above technical solutions effectively prevent the threaded sleeve from rotating or shifting during movement, ensuring the stability and accuracy of the horizontal movement of the threaded sleeve, and thus ensuring the smoothness of the horizontal movement of the end cap body.

[0011] Preferably, a rotating column is rotatably connected to the inner walls of both sides of the mounting base, a second gear disk is fixedly connected to the outer circumference of the rotating column, and a rack is fixedly connected to the top outer wall of the threaded sleeve, the rack meshing with the second gear disk.

[0012] The above technical solution converts the horizontal movement of the threaded sleeve into the rotational motion of the rotating column, providing a power basis for the subsequent rotation of the end cap body.

[0013] Preferably, a second helical gear is fixedly connected to one end of the rotating column, and a first helical gear meshes with the outer circumferential wall of the second helical gear. A triangular plate is fixedly connected to one side of the outer wall of the mounting base, and a rotating rod is fixedly connected to the inner circumferential wall of the first helical gear. The rotating rod is rotatably connected to the triangular plate.

[0014] Through the above technical solutions: the triangular plate provides stable rotational support for the rotating rod, while the meshing transmission of the helical gear changes the direction of power transmission, making it easier to transmit the rotational power of the rotating column to subsequent components.

[0015] Preferably, a transmission wheel is fixedly connected to the outer circumference of the triangular plate, and a transmission belt is driven to the outer circumference of the transmission wheel. The transmission wheel is driven to another transmission wheel through the transmission belt.

[0016] The above technical solutions enable long-distance power transmission between two drive wheels, ensuring the continuity and stability of power transmission.

[0017] Preferably, the rotating assembly includes a rotating rod fixedly connected to the inner circumference of another transmission wheel, with both ends of the rotating rod rotatably connected to the support plate, and a gear column fixedly connected to the outer circumference of the rotating rod. A first gear disk meshes with the outer circumference of the gear column, and the first gear disk is fixedly connected to the outer circumference of the connecting column.

[0018] The above technical solution enables the synchronous rotational opening action during the horizontal movement of the end cap body. The rotating component has precise transmission and can reliably control the rotation angle of the end cap body, ensuring the smooth completion of the end cap opening action.

[0019] The beneficial effects of this utility model are as follows: by setting the lateral movement component and the rotation component to work in coordination, the horizontal movement of the end cap body and the 90-degree rotation opening action are realized simultaneously. No additional operation steps are required, which greatly improves the efficiency of end cap opening. At the same time, the whole process can be completed in a small space, which effectively solves the problem of inconvenience in operation of traditional equipment in a narrow space. It is especially suitable for work scenarios with limited space, which enhances the applicability of the equipment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0026] Reference Figures 1-4 A 90-degree rotating boom for opening the end cap of a horizontal equipment includes a mounting base 4 fixedly connected to the outer circumference of the tank body 1. A connecting column 10 is provided on one side of the mounting base 4. A horizontal column 19 is fixedly connected to one end of the connecting column 10. A limiting plate 21 is fixedly connected to one end of the horizontal column 19. A threaded column 20 is fixedly connected to one side of the outer wall of the limiting plate 21. The threaded column 20 passes through the center of the lifting lug 18 fixedly connected to one side of the outer wall of the end cap body 2. A nut 22 is threadedly connected to the outer circumference of the threaded column 20. One side of the mounting base 4 is provided with a transverse moving component for driving the end cap body 2 to move horizontally; The mounting base 4 is equipped with a rotating component for rotating and opening the end cap body 2 during horizontal movement. This enables a detachable connection between the end cap body 2 and the boom, ensuring a secure connection and facilitating the installation and maintenance of the end cap body 2. The horizontal movement component can drive the end cap body 2 to move horizontally, while the rotating component can drive the end cap body 2 to rotate while it is moving horizontally. The two work together to achieve simultaneous horizontal movement and 90-degree rotation opening of the end cap body 2.

[0027] Furthermore, the transverse movement assembly includes a motor 3 fixedly connected to the outer wall of one side of the mounting base 4. A threaded screw 23 is fixedly connected to the output end of the motor 3. A threaded sleeve 24 is threadedly connected to the outer circumference of the threaded screw 23. A bent column 7 is fixedly connected to the top outer wall of the threaded sleeve 24. A support plate 6 is fixedly connected to one end of the bent column 7. The support plate 6 is fixedly connected to the mounting base 4. The end of the connecting column 10 away from the transverse column 19 is rotatably connected to the support plate 6. The motor 3 serves as a power source, driving the threaded screw 23 to rotate. The threaded sleeve 24 moves horizontally under the action of the threaded screw 23, which in turn drives the support plate 6 to move through the bent column 7. Since the connecting column 10 is rotatably connected to the support plate 6, the movement of the support plate 6 will drive the connecting column 10 and the head body 2 connected to it to move horizontally. This assembly has a simple structure, precise transmission, and can stably and reliably drive the head body 2 to complete the horizontal displacement.

[0028] Furthermore, a guide post 25 is fixedly connected inside the mounting base 4. A guide block 26 is sleeved on the outer circumference of the guide post 25. The guide block 26 is fixedly connected to the threaded sleeve 24. The cooperation between the guide post 25 and the guide block 26 plays a guiding role. When the threaded sleeve 24 moves under the drive of the threaded screw 23, the guide block 26 will move synchronously along the guide post 25, which effectively prevents the threaded sleeve 24 from rotating or deviating during the movement, ensuring the stability and accuracy of the horizontal movement of the threaded sleeve 24, and thus ensuring the smoothness of the horizontal movement of the end cap body 2.

[0029] Furthermore, rotating columns 13 are rotatably connected to the inner walls of both sides of the mounting base 4. A second gear disk 11 is fixedly connected to the outer circumference of the rotating column 13. A rack 12 is fixedly connected to the outer top wall of the threaded sleeve 24. The rack 12 meshes with the second gear disk 11. When the threaded sleeve 24 moves horizontally, the rack 12 at its top will move accordingly. Since the rack 12 meshes with the second gear disk 11, the movement of the rack 12 will drive the second gear disk 11 to rotate, thereby causing the rotating column 13 to rotate synchronously. This realizes the conversion of the horizontal movement of the threaded sleeve 24 into the rotational movement of the rotating column 13, providing a power basis for subsequently driving the head body 2 to rotate.

[0030] Furthermore, a second helical gear 17 is fixedly connected to one end of the rotating column 13. A first helical gear 14 meshes with the outer circumference of the second helical gear 17. A triangular plate 16 is fixedly connected to the outer side of the mounting base 4. A rotating rod 15 is fixedly connected to the inner circumference of the first helical gear 14. The rotating rod 15 is rotatably connected to the triangular plate 16. When the rotating column 13 rotates, it will drive the second helical gear 17 to rotate. Since the second helical gear 17 meshes with the first helical gear 14, the rotation of the second helical gear 17 will drive the first helical gear 14 to rotate, thereby causing the rotating rod 15 to rotate under the support of the triangular plate 16. The triangular plate 16 provides stable rotational support for the rotating rod 15. At the same time, the meshing transmission of the helical gears changes the direction of power transmission, making it easier to transmit the rotational power of the rotating column 13 to subsequent components.

[0031] Furthermore, a transmission wheel 27 is fixedly connected to the outer circumference of the triangular plate 16, and a transmission belt 8 is connected to the outer circumference of the transmission wheel 27. The transmission wheel 27 is connected to another transmission wheel 27 through the transmission belt 8. When the rotating rod 15 rotates, it will drive the transmission wheel 27 on the triangular plate 16 to rotate. Under the action of the transmission belt 8, the transmission wheel 27 will drive the other transmission wheel 27 to rotate synchronously. The transmission method of the transmission belt 8 has the advantages of simple structure, smooth transmission, and low cost. It can realize long-distance power transmission between the two transmission wheels 27, ensuring the continuity and stability of power transmission.

[0032] Furthermore, the rotating assembly includes a rotating rod fixedly connected to the inner circumference of another transmission wheel 27. The two ends of the rotating rod are rotatably connected to the support plate 6. A gear column 5 is fixedly connected to the outer circumference of the rotating rod. A first gear disk 9 meshes with the outer circumference of the gear column 5. The first gear disk 9 is fixedly connected to the outer circumference of the connecting column 10. When the other transmission wheel 27 rotates, it will drive the rotating rod to rotate, and the gear column 5 on the rotating rod will rotate accordingly. Since the gear column 5 meshes with the first gear disk 9, the rotation of the gear column 5 will drive the first gear disk 9 to rotate, thereby causing the connecting column 10 to rotate. The rotation of the connecting column 10 will drive the end cap body 2 to rotate, realizing the synchronous completion of the rotation opening action during the horizontal movement of the end cap body 2. This rotating assembly has precise transmission and can reliably control the rotation angle of the end cap body 2, ensuring the smooth completion of the end cap opening action.

[0033] Working principle: During operation, the threaded column 20 first passes through the lifting lug 18 of the head body 2 and, in conjunction with the nut 22 and the limiting plate 21, achieves a stable connection between the head body 2 and the connecting column 10, providing a reliable foundation for subsequent operations. When the motor 3 is started, its output end drives the threaded screw 23 to rotate. The threaded sleeve 24 moves horizontally under the action of the threaded screw 23. At the same time, the cooperation of the guide column 25 and the guide block 26 can precisely limit the movement trajectory of the threaded sleeve 24, avoid deviation, ensure stability during the lateral movement, and improve the overall accuracy of the operation. When the threaded sleeve 24 moves, on the one hand, the bent column 7 drives the connecting column 10 on the support plate 6 to move horizontally synchronously, realizing the initial translation of the head body 2. On the other hand, the rack 12 at the top of the threaded sleeve 24 meshes with the second gear disk 11 on the rotating column 13, causing the rotating column 13 to rotate. The rotating column 13 is driven by the meshing of the second helical gear 17 and the first helical gear 14, causing the rotating rod 15 to rotate. This causes the transmission wheel 27 on the triangular plate 16 to drive another transmission wheel 27 to rotate through the transmission belt 8. This multi-component collaborative transmission method ensures the high efficiency and stability of power transmission. The other transmission wheel 27 drives the rotating rod and the gear column 5 to rotate. The gear column 5 meshes with the first gear disk 9 on the connecting column 10, causing the connecting column 10 to rotate 90 degrees while moving horizontally, thereby driving the end cap body 2 to complete the rotation opening action. Throughout the process, the lateral movement and rotation are carried out simultaneously without any additional operating steps, which greatly improves the efficiency of opening the end cap. It can complete a 90-degree rotation in a small space, making it particularly suitable for space-constrained scenarios. It solves the problem of inconvenient operation of traditional equipment in confined spaces. At the same time, the coordinated transmission of various gears, transmission belts, and other components ensures the smoothness and accuracy of the operation, reducing the risk of equipment damage caused by improper operation during the opening of the end cap.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
