Description

Technical Field

[0001] This invention relates to the field of locomotive manufacturing technology, and in particular to a roof rotation support device. Background Technology

[0002] Urban rail vehicles are core equipment for urban public transportation. Their roofs, as large body coverings, widely utilize lightweight materials such as aluminum alloys and composite materials. Due to aerodynamic, aesthetic, and modern industrial design requirements, roofs are often complex spatial curved surfaces rather than simple planes. Their structural design is quite complex, and there are high requirements for assembly gaps, surface differences, and surface treatment. Equipment mounting holes (such as lights, air conditioners, and access ports) also need precise positioning. During the manufacturing, interior installation, equipment assembly, and maintenance of the roof, frequent positioning, clamping, flipping, and angle adjustments are required. Therefore, roof rotation support tools are needed. However, existing roof rotation support tools and fixtures typically design "clamping the workpiece" and "locking the angle" as two independent, unrelated operations. Workers need to adjust the angle first and then operate a separate locking mechanism. Before adjusting the roof to a certain angle and preparing to finally fix it through the locking mechanism, there is a lack of a pre-positioning mechanism. Operators need to try to maintain the roof's angle while tightening the locking mechanism, making the operation difficult and prone to adjustment errors. Summary of the Invention

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] To solve the above problems, such as Figures 1 to 10 As shown, the present invention provides a roof rotation support device, including a base 11, a rotating column 12 mounted on the base 11, a clamping part mounted on the rotating column 12, the clamping part clamping the roof, a fixing plate 13 mounted on the outer periphery of the rotating column 12, a screw 16 threaded through and screwed into the fixing plate 13, a fixing block 17 provided on the base 11, a threaded hole 20 provided on the fixing block 17, the screw 16 being screwed into the threaded hole 20, a positioning post 30 extending from the lower side of the fixing plate 13, a first positioning hole 21 provided on the fixing block 17, a guide platform 18 formed on one side of the fixing block 17, and the first positioning hole 21 being located on the top of the guide platform 18.

[0022] One end of the fixing box 22 is integrally formed with the fixing plate 13. The position through which the screw 16 passes through the fixing plate 13 is the space inside the fixing box 22. Two sets of fixing boxes 22 are arranged around the fixing plate 13. Each set of fixing boxes 22 corresponds one-to-one with the screw 16 and the positioning post 30. Connecting the fixing plate 13 and the fixing block 17 with the two sets of screws 16 can improve the stability of the ceiling rotation support device after it is fixed.

[0023] It should be noted that fixing blocks 17 can be installed at various angles around the base 11 corresponding to the fixing plate 13, allowing the fixing plate 13 to be fixed at different angles of rotation, thus enabling the ceiling to rotate at more angles and allowing the device to be used in different scenarios.

[0024] When screw 16 is removed from threaded hole 20, screw 16 drives the transmission component to pull positioning pin 30 out of first positioning hole 21. Rotating pin 12 can then drive fixed plate 13 to rotate flexibly. When fixed plate 13 rotates, the transmission component will drive positioning pin 30 to extend again. Positioning pin 30 slides along guide plate 18, which is an inclined surface. Positioning pin 30 abuts against the inclined surface and retracts into fixed box 22 as the rotation angle increases. A first spring 31 is installed at the rear end of positioning pin 30. The first spring 31 is gradually compressed. When positioning pin 30 moves to a new angle... When the fixed block 17 is at the latest angle, the first spring 31 is released, and the positioning pin 30 is inserted into the first positioning hole 21 at the latest angle. At this time, the fixed plate 13 and the fixed block 17 can be pre-fixed, which makes it easy for the operator to screw the screw 16 into the threaded hole 20 to fix the rotation angle of the fixed plate 13. During the screwing process, since the positioning pin 30 and the fixed plate 13 are pre-fixed, the operator only needs to screw in the screw 16 without paying attention to other parts. The operation is simpler and can also improve the clamping accuracy and operating efficiency.

[0025] The transmission component of this invention includes a fixed box 22, a connecting box 39 installed in the middle of the fixed box 22, a first rack 41 installed inside the connecting box 39, a second spring 42 installed on the lower side of the first rack 41, a pressure block 15 provided on the top of the screw 16, a pressure ring 14 placed below the pressure block 15, the pressure ring 14 pressing against the upper side of the first rack 41, the first rack 41 meshing with a second drive gear 34, a one-way bearing provided inside the second drive gear 34, a rotating rod 32 installed inside the one-way bearing, the rotating rod 32 driving a threaded rod 23 to rotate through the transmission component, the threaded rod 23 passing through... Inside the threaded hole formed by the extension plate on one side of the piston rod 28, the threaded rod 23 drives the piston rod 28 to move along its own axis. The piston rod 28 is inserted into the first piston cylinder 25. The cavity inside the first piston cylinder 25 is connected to the first liquid bladder 29 in the drive box 40 through the connecting pipe 27. A first spring 31 is installed inside the drive box 40. The positioning pin 30 extends out from the drive box 40. The first spring 31 is located on the side away from the first liquid bladder 29. A first drive gear 24 is formed on the lower side of the threaded rod 23. A toothed segment 19 is installed on the base 11. The first drive gear 24 meshes with the toothed segment 19.

[0026] Before adjusting the ceiling rotation, unscrew screw 16 from the threaded hole 20 to release its limiting fixation to the fixed plate 13. With screw 16 removed, pressure block 15 moves upward, allowing second spring 42 to push first rack 41, which in turn pushes pressure ring 14 upward. First rack 41 then drives second drive gear 34, which in turn drives rotating rod 32. Rotating rod 32, via first pulley 35, drives another first pulley 35 connected to it, causing drive rod 36 to rotate. Drive rod 36 then drives bevel gear 37 and connecting rod 55 to rotate. Connecting rod 55, via a second pulley 38, drives the belt... Another second pulley 38 rotates, causing the second pulley 38 to drive the threaded rod 23 to rotate. The threaded rod 23 drives the piston rod 28 to move upward, causing the piston rod 28 to drive the liquid inside the first piston cylinder 25 to enter the first liquid bladder 29 through the connecting pipe 27. This causes the first liquid bladder 29 to expand, causing the first liquid bladder 29 to overcome the thrust of the first spring 31 and push the upper end of the positioning post 30 to move upward. The positioning post 30 retracts, causing the upper end of the positioning post 30 to squeeze the first spring 31. The positioning post 30 moves out of the first positioning hole 21, releasing the restriction on the fixed plate 13. At this time, the fixed plate 13 can be rotated, and the angle of the roof can be rotated. At this time, the fixed plate 13 will also drive the circumferential fixed box 22 to move in a circle.

[0027] Before the ceiling reaches the appropriate angle, the first drive gear 24 will first contact the tooth segment 19. As the first drive gear 24 moves, it drives the threaded rod 23 to rotate. The threaded rod 23 drives the piston rod 28 to move downward, causing the liquid inside the first liquid bladder 29 to flow back into the first piston cylinder 25 through the connecting pipe 27, causing the first liquid bladder 29 to contract. At this time, the elastic force of the first spring 31 is released, pushing the positioning pin 30 to move downward, causing the positioning pin 30 to extend from the bottom end. At this time, the threaded rod 23 will also drive the connecting rod 55 to rotate through the second pulley 38. This causes the connecting rod 55 to drive the bevel gear 37, the driving rod 36, the rotating shaft 3, and the rotating rod 32 to rotate. The rotating rod 32 drives the second driving gear 34 to reset and rotate. However, at this time, the first rack 41 is in an extended state and does not contact the second driving gear 34. The second driving gear 34 is misaligned with the first rack 41, so that the position of the first rack 41 is not affected. At this time, the fixed plate 13 drives the extended positioning pin 30 to move, so that the bottom end of the positioning pin 30 contacts the surface of the guide plate 18. As the positioning pin 30 moves, the inclined surface at the top of the guide plate 18 pushes the positioning pin 30. The bottom end of the 0 moves upward, causing the upper end of the positioning pin 30 to press against the first spring 31. When the bottom end of the positioning pin 30 moves above the first positioning hole 21, the first spring 31 pushes the positioning pin 30 downward, causing the bottom end of the positioning pin 30 to insert into the first positioning hole 21, pre-fixing the position of the fixing plate 13. Then, the operator can tighten the screw 16, causing the bottom end of the screw 16 to be screwed into the threaded hole 20, causing the pressure block 15 on the outside of the screw 16 to move downward, pushing the pressure ring 14 downward, causing the pressure ring 14 to push the first rack 41 downward. Due to the one-way setting... The bearing prevents the first rack 41 from driving the rotating rod 32 to rotate via the second drive gear 34 until the bottom end of the screw 16 is screwed into the threaded hole 20, thus fixing the positions of the fixed plate 13, rotating column 12, mounting base 1 and positioning block 2, as well as the crank arm 4 and clamping block 9. Before tightening the screw 16, it is pre-fixed by the positioning column 30, allowing the operator to focus on tightening the screw 16, reducing the difficulty of operating the ceiling rotation support device, and enabling the operator to achieve pre-fixation after rotating and adjusting the ceiling. Finally, the ceiling will not shake during the tightening of the screw 16.

[0028] The roof rotation support device of the present invention is further provided with a clamping part, which can fix the roof on the roof rotation support device, so as to facilitate the rotation adjustment angle of the fixing plate 13. The clamping part includes a mounting base 1 and a fixing member 5. The fixing member 5 is provided on the side of the mounting base 1. A positioning member 10 is installed on the fixing member 5. A positioning block 2 is installed on the top of the mounting base 1. The bottom of the mounting base 1 is installed on the rotating column 12. The roof is placed on the positioning member 10 and the positioning block 2. The crank arm 4 is installed on the fixing member 5 through the rotating shaft 3. A threaded sleeve 6 is installed at the end of the crank arm 4. A screw 8 is screwed into the threaded sleeve 6. A clamping block 9 is installed at the bottom of the screw 8. The clamping block 9 is pressed against the roof. A fixing ring 7 is installed on the lower side of the screw 8. The lower side of the fixing ring 7 abuts against a second A rack 44 is inserted into a guide box 43. A fixed cylinder 46 is installed on the guide box 43. A threaded column 47 is rotatably installed inside the fixed cylinder 46. A piston block 49 is screwed onto the threaded column 47. A third drive gear 45 is formed at one end of the threaded column 47. The third drive gear 45 meshes with the second rack 44. A second piston cylinder 48 is formed on the side of the piston block 49 away from the second rack 44. The second piston cylinder 48 is connected to the second liquid bladder 52 of the drive cylinder 51 through a pipe 50. A positioning rod 53 is slidably installed inside the drive cylinder 51. The positioning rod 53 abuts against a third spring 54. The third spring 54 is installed on the side away from the second liquid bladder 52. The positioning rod 53 is inserted into the second positioning hole 56 on the fixing member 5.

[0029] In use, the canopy is placed on top of the positioning block 2. Then, by rotating the crank arm 4, the crank arm 4 rotates around the rotating shaft 3, causing the clamping block 9 to rotate to a fixed position. Then, the user turns the screw 8, causing the screw 8 to drive the fixing ring 7 to rotate synchronously. One end of the screw 8 pushes the clamping block 9 downward, and through the cooperation of the positioning element 10 and the clamping block 9, the canopy is clamped and limited. At the same time, as the fixing ring 7 moves downward synchronously with the screw 8, the fixing ring 7 pushes the second rack 44 downward, causing the second rack 44 to drive the third drive gear 45 to rotate. The third drive gear 45 drives the same... The rotation of the threaded post 47 of the shaft drives the piston block 49 to move. The piston block 49 pushes the liquid inside the second piston cylinder 48 through the pipe 50 into the second liquid bladder 52, causing the second liquid bladder 52 to expand and overcome the supporting force of the third spring 54. The second liquid bladder 52 pushes one end of the positioning rod 53 into the second positioning hole 56, limiting and fixing the rotation angle of the crank arm 4 and the clamping block 9. The angle of the crank arm 4 is limited by the clamping block 9 abutting against the ceiling, which can shorten the fixing steps, improve the fixing efficiency, and simplify the operation process.

[0030] After the roof is processed, the user resets and rotates the screw 8, causing the screw 8 to drive the clamping block 9 to move upward. At this time, the screw 8 drives the fixing ring 7 to move upward, and the fixing ring 7 drives the second rack 44 to move upward, causing the second rack 44 to drive the third drive gear 45 to reset and rotate. The third drive gear 45 drives the threaded column 47 to reset and rotate, and the threaded column 47 drives the piston block 49 to reset and move. The liquid inside the second liquid bladder 52 flows back to the inside of the second piston cylinder 48 through the pipe 50. The second liquid bladder 52 contracts. At this time, the third spring 54 pushes one end of the positioning rod 53 to move into the drive cylinder 51, so that one end of the positioning rod 53 moves out of the second positioning hole 56, releasing the angle limit on the crank arm 4, the threaded sleeve 6, and the clamping block 9, and releasing the clamping block 9 from the limiting state of the car roof, simplifying the disassembly steps.

[0031] The fastener 5 is stepped, and the positioning part 10 is installed on the fastener 5 by bolts. The fastener 5 has elongated holes, through which the bolts pass and are fixed with nuts. The fastener 5 has multiple elongated holes, which can flexibly change the installation position of the positioning part 10 to adapt to different types of ceilings.

[0032] The first liquid bladder 29 and the second liquid bladder 52 are filled with hydraulic oil. The hydraulic oil is used to achieve a self-locking state and can stably push the components to move and achieve a tightened state.

[0033] The connecting box 39 is located in the middle of the fixed box 22. One side of the connecting box 39 has a screw 16 and the other side has a positioning post 30. The fixed box 22 is divided into two by the connecting box 39, so that the screw 16 and the positioning post 30 can work independently and avoid mutual interference.

[0034] A first plate and a second plate are provided on both sides of the piston column 28. The first plate is located inside the first piston cylinder 25. The inner wall of the opening of the second plate is threaded, and the threaded rod 23 passes through the opening. The piston column 28 can drive the first plate and the second plate to move in parallel, realizing the linkage of the two components while pushing the hydraulic fluid to move.

[0035] The transmission components of the present invention include a first pulley 35, a drive rod 36, a bevel gear 37, a connecting rod 55, and a second pulley 38. The rotating rod 32 drives the drive rod 36 to rotate via the first pulley 35. The end of the drive rod 36 is provided with a bevel gear 37, which drives the connecting rod 55 to rotate. The connecting rod 55 drives the threaded rod 23 to rotate via the second pulley 38. The transmission of the above components is realized within the fixed box 22, reducing the overall size of the drive device.

[0036] The transmission components are arranged in a U-shape to form a placement area. The drive box 40 and the first piston cylinder 25 are located in the placement area. This allows for higher space utilization within the fixed box 22, enabling the installation of more parts without interference.

[0037] An auxiliary plate is installed in the gap between the placement area and the fixed box 22. The drive rod 36 passes through the auxiliary plate. Since the distance of the drive rod 36 is relatively long, the stability of the drive rod 36 during rotation can be improved by setting the auxiliary plate, thereby improving its reliability.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
