[0001] The application belongs to the technical field of water conservancy and hydropower, more specifically, relates to a pipeline supporting device for construction. BACKGROUND

[0002] In the process of water conservancy and hydropower engineering construction, especially in the laying and maintenance of underground pipelines, the application of supporting devices is crucial. Supporting devices are mainly used to provide stable support to ensure the smooth progress of pipeline installation and maintenance work. Temporary supporting devices are used to stably support the pipeline before it is transported or not fixed, so as to facilitate the subsequent installation and fixation of the pipeline.

[0003] The existing temporary supporting device includes a hydraulic lifting platform and a supporting seat. The height of the supporting seat is adjusted by the hydraulic lifting platform to support the pipeline.

[0004] When the pipeline is subsequently installed and fixed, if the position of the pipeline needs to be adjusted along its length direction, in order to ensure the uniform stress of the pipeline, the position of the temporary supporting device needs to be adjusted to change the supporting point of the temporary supporting device on the pipeline. However, due to the supporting friction between the supporting seat and the pipeline, the movement of the temporary supporting device is relatively inconvenient, and the pipeline needs to be lifted to move the hydraulic lifting platform, which affects the progress of pipeline construction work. SUMMARY

The support roller has a first state and a second state. In the first state, the support roller is located in the receiving cavity and the inner wall of the arc-shaped groove is in contact with the pipe. In the second state, the top of the support roller is located in the arc-shaped groove and supports the pipe. In one possible implementation, based on the above technical solutions, the upper surface of the lifting seat has lifting openings located on both sides of the arc-shaped groove. These lifting openings correspond one-to-one with and communicate with the receiving cavities, allowing the support rollers to pass through. The pipe support device further includes: A translation component is mounted on the vehicle body and connected to the two lifting cylinders. The translation component is used to simultaneously drive the two lifting cylinders to move in opposite directions until the support roller moves to below the corresponding lifting port. Two connecting seats are provided, each corresponding to one of the two lifting cylinders, and are mounted on the piston rod of the lifting cylinder. Two rotating brackets, each corresponding to one of the two connecting seats, are rotatably mounted on the connecting seats; and Two sets of rotating mechanisms are arranged between the corresponding connecting seat and the rotating frame; The support roller is rotatably mounted on the rotating frame. The rotating mechanism is used to drive the rotating frame to rotate toward the pipe when the lifting cylinder drives the support roller to rise above the lifting port, until the support roller abuts against the outer circumferential surface of the upper part of the pipe. At this time, the support roller is in the third state.

[0007] In one possible implementation, based on the above technical solutions, the pipe support device further includes: Two sets of rotating components correspond one-to-one with the two connecting seats and are disposed between the connecting seats and the piston rod of the lifting cylinder; The connecting seat is rotatably connected to the piston rod of the lifting cylinder, and the rotation axis of the connecting seat is vertically oriented.

A positioning component, mounted on the lifting seat, is used to fix the rotation angle of the guide plate; and A rotary assembly is disposed on the lifting seat and located on the side of the lifting port near the arc-shaped groove.

[0011] In conjunction with the above technical solutions, in one possible implementation, the limiting component further includes: A ratchet, coaxially fixed to the end of the rotating shaft away from the rotating gear; and A pawl is rotatably mounted on the movable rod and is used to engage with the ratchet; when the pawl is engaged with the ratchet, the rotating frame can only rotate toward the pipe. When the lifting cylinder drives the rotating frame to rise toward the lifting port, the moving component drives the rotating gear to separate from the positioning gear and drives the pawl to engage with the ratchet; when the lifting cylinder drives the rotating frame to rotate back into the lifting port, the moving component drives the pawl to separate from the ratchet, while the rotating gear and the positioning gear remain separated.

[0012] In one possible implementation, based on the above technical solutions, the positioning component includes: A positioning plate is fixed on the lifting seat and located on the side of the lifting seat away from the arc-shaped groove; A sliding plate is slidably disposed on the lifting seat and facing the positioning plate; the guide plate is located between the positioning plate and the sliding plate; A positioning bolt passes sequentially through the positioning plate, the guide plate, and the sliding plate; and The positioning nut is threaded onto the positioning bolt and abuts against the outside of the sliding plate.

[0013] In one possible implementation, based on the above technical solutions, the rotating component includes: A fixing plate is fixed to the lifting seat and located on the side of the lifting seat near the arc-shaped groove; A push plate, slidably mounted on the lifting seat and facing the lifting opening; and A return spring is connected between the fixed plate and the push plate; When the rotating frame rises above the lifting port, it pushes the push plate toward the fixed plate, and the return spring is compressed; when the rotating frame descends to reset, the return spring drives the push plate to push the rotating frame to a vertical position.

[0014] In one possible implementation, based on the above technical solutions, the rotating component includes: A fixed plate is fixed to the top of the piston rod of the lifting cylinder; A rotating disk, rotatably connected to the fixed disk, wherein the axis of the rotating disk is vertically arranged; and A push cylinder is horizontally mounted on the fixed disk.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] It should be further noted that the accompanying drawings and embodiments of this application mainly describe the concept of this application. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this application, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0021] The present application provides a description of a construction pipe support device.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this application provides a construction pipe support device, including a vehicle body 1, a lifting seat 2, two lifting cylinders 3, and two support rollers 4. Multiple drive cylinders 11 are vertically arranged on the upper surface of the vehicle body 1.

[0023] The lifting seat 2 is located above the vehicle body 1 and is connected to the piston rods of all drive cylinders 11. The top of the lifting seat 2 has an arc-shaped groove 21 for placing pipes, and the bottom of the lifting seat 2 has two receiving cavities (not shown in the figure) that are both connected to the arc-shaped groove 21.

[0024] Two lifting cylinders 3 correspond one-to-one with two receiving cavities. The lifting cylinders 3 are vertically mounted on the vehicle body 1 and located inside the receiving cavities. Two support rollers 4 correspond one-to-one with the two lifting cylinders 3 and are rotatably mounted on the piston rods of the lifting cylinders 3. The axis of the support rollers 4 is perpendicular to the axis of the pipe.

[0025] The lifting cylinder 3 is used to drive the support roller 4 to move up and down between the receiving cavity and the arc-shaped groove 21. The support roller 4 has a first state and a second state. In the first state, the support roller 4 is located in the receiving cavity and the inner wall of the arc-shaped groove 21 is in contact with the pipe. In the second state, the top of the support roller 4 is located in the arc-shaped groove 21 and supports the pipe.

[0026] The pipeline support device provided in this embodiment, compared with the prior art, has the following features: when supporting the pipeline, the support roller 4 is located in the receiving cavity, and the inner wall of the arc-shaped groove 21 on the lifting seat 2 is in contact with the outer circumferential surface of the pipeline to ensure stable support for the pipeline.

[0027] When it is necessary to change the support position of the pipeline, the lifting cylinder 3 drives the two support rollers 4 to rise to contact the bottom of the pipeline, and then the drive cylinder 11 drives the lifting seat 2 to fall, so that the two support rollers 4 support the pipeline. The moving vehicle body 1 can realize the rolling of the support rollers 4 under the pipeline, which improves the efficiency of changing the pipeline support point while keeping the pipeline height unchanged, thus ensuring the smooth progress of pipeline construction operations.

[0028] Moreover, the inclusion cavity allows the support roller 4 to be completely stored inside the lifting seat 2 when not in use, without taking up additional space in the device, making it easier to move in confined construction spaces.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The upper surface of the lifting seat 2 is provided with lifting ports 22 on both sides of the arc-shaped groove 21. The lifting ports 22 correspond to and are connected to the receiving cavity, and allow the support roller 4 to pass through. The pipe support device also includes a translation component 5, two connecting seats 6, two rotating frames 7 and two sets of rotating mechanisms 8.

[0030] The translation component 5 is mounted on the vehicle body 1 and connected to two lifting cylinders 3. The translation component 5 is used to simultaneously drive the two lifting cylinders 3 to move in opposite directions until the support roller 4 moves to below the corresponding lifting port 22.

[0031] The two connecting seats 6 correspond one-to-one with the two lifting cylinders 3 and are mounted on the piston rods of the lifting cylinders 3.

[0032] Two rotating frames 7 correspond one-to-one with two connecting seats 6 and are rotatably mounted on the connecting seats 6. Two sets of rotating mechanisms 8 are arranged between the corresponding connecting seats 6 and the rotating frames 7.

[0033] The support roller 4 is rotatably mounted on the rotating frame 7. The rotating mechanism 8 is used to drive the rotating frame 7 to rotate toward the pipe when the lifting cylinder 3 drives the support roller 4 to rise above the lifting port 22, until the support roller 4 is pressed against the outer circumferential surface of the upper part of the pipe. At this time, the support roller 4 is in the third state, and the force of the support roller 4 on the pipe is directed toward the arc-shaped groove 21.

[0034] When the arc-shaped groove 21 on the lifting seat 2 contacts and supports the pipe, the support roller 4 is in the first state. At this time, the lifting assembly drives the two lifting cylinders 3 to move in opposite directions until the two support rollers 4 move directly below the corresponding lifting port 22. Then, the lifting cylinder 3 drives the support roller 4 to rise above the lifting port 22, and at the same time, the rotating mechanism 8 drives the rotating frame 7 to move towards the pipe until the support roller 4 is pressed against the upper part of the pipe. This changes the support roller 4 from "bottom support of the pipe" to "upper part pressed against the pipe", forming an "upper and lower clamping" state with the arc-shaped groove 21 on the lifting seat 2, which improves the stability of the pipe support and the smoothness of subsequent installation and fixing.

[0035] Moreover, the integrated design of the rotating frame 7, connecting seat 6 and lifting cylinder 3 allows the steering action of the support roller 4 to be completed compactly around the lifting seat 2 without taking up extra lateral space, making it more suitable for construction in restricted spaces such as underground tunnels and narrow machine rooms.

[0036] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The pipe support device also includes two sets of rotating components 9, which correspond one-to-one with two connecting seats 6 and are arranged between the connecting seats 6 and the piston rod of the lifting cylinder 3.

[0037] The connecting seat 6 is rotatably connected to the piston rod of the lifting cylinder 3, and the rotation axis of the connecting seat 6 is set vertically. The rotating component 9 is used to drive the connecting seat 6 to rotate 90° when the support roller 4 switches to the third state, so that the rotation axis of the support roller 4 is parallel to the pipeline axis.

[0038] During the transition of the support roller 4 from the first state to the third state, the rotating component 9 can first drive the support roller 4 to rotate horizontally by 90° before the lifting cylinder 3 drives the support roller 4 to rise to the lifting port 22, so that the rotation axis of the support roller 4 is parallel to the pipeline axis. On the one hand, this can increase the contact area between the support roller 4 and the pipeline, improve the stability of the interaction between the support roller 4 and the pipeline, and on the other hand, it can convert the friction between the support roller 4 and the outer wall of the pipeline into rolling friction, reduce the friction between the support roller 4 and the outer wall of the pipeline, and improve the safety and service life of both.

[0039] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The rotating assembly 9 includes a fixed disk 91, a rotating disk 92, and a push cylinder 93. The fixed disk 91 is fixed to the top of the piston rod of the lifting cylinder 3. The rotating disk 92 is rotatably connected to the fixed disk 91, and the axis of the rotating disk 92 is vertically oriented. The push cylinder 93 is horizontally oriented on the fixed disk 91, with one end hinged to the fixed disk 91 and the other end hinged to the rotating disk 92. The hinge axes at both ends of the push cylinder 93 are vertically oriented.

[0040] During the process of switching the support roller 4 to the third state or returning from the third state to the first state, the piston rod of the push cylinder 93 is activated to push the rotating disk 92 or pull back the rotating disk 92, so that the rotating frame 7 and the support roller 4 can be rotated horizontally by 90°. This not only improves the horizontal rotation efficiency of the support roller 4, but also achieves a compact structure.

[0041] like Figure 3 and Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The rotating mechanism 8 includes a limiting component 81, a guide plate 82, a positioning component 83, and a rotation component 84. The limiting component 81 is disposed between the connecting seat 6 and the rotating frame 7, and is used to fix or release the rotation state of the rotating frame 7.

[0042] The guide plate 82 is rotatably mounted on the lifting seat 2 and located on the side of the lifting port 22 away from the arc-shaped groove 21. The guide plate 82 is inclined toward the pipe and guides the rotating frame 7 that rises out of the lifting port 22, so as to drive the support roller 4 to rotate onto the pipe.

[0043] The positioning component 83 is mounted on the lifting base 2 and is used to fix the rotation angle of the guide plate 82. The rotation component 84 is mounted on the lifting base 2 and is located on the side of the lifting port 22 near the arc-shaped groove 21. The rotation component 84 is used to drive the rotating frame 7 to rotate back to the vertical state when the rotating frame 7 descends.

[0044] In the second state, the limiting component 81 fixes the rotation state of the rotating frame 7 to improve the support stability of the support roller 4 on the pipeline. During the process of the support roller 4 returning to the first state and switching to the third state, when the lifting cylinder 3 drives the support roller 4 to rise to the lifting port 22, the limiting component 81 releases the fixing state of the rotating frame 7. At this time, the lifting cylinder 3 continues to drive the support roller 4 to rise, and the guide plate 82 guides the support roller 4 and the rotating frame 7 so that the support roller 4 and the rotating frame 7 automatically rotate towards the pipeline until the support roller 4 abuts against the upper part of the pipeline, improving the automation accuracy and reliability of the support roller 4 state switching.

[0045] Furthermore, the positioning component 83 allows for adjustment of the angle of the guide plate 82, thereby altering the rotation trajectory of the support roller 4 and the rotating frame 7 to accommodate pipes of different sizes. When the support roller 4 returns from the third state to the receiving cavity, the lifting cylinder 3 drives the rotating frame 7 and the support roller 4 to descend. Simultaneously, the rotation component 84 drives the rotating frame 7 to automatically return to the vertical state, and the limiting component 81 then fixes the rotation state of the rotating frame 7 again, improving the operating efficiency and stability of the rotating mechanism 8.

[0046] like Figure 4 to Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: A rotating shaft 71 is fixed to the bottom of the rotating frame 7, and the rotating shaft 71 is rotatably connected to the connecting seat 6. The limiting assembly 81 includes a rotating gear 811, a positioning gear 812, and a moving member 813. The rotating gear 811 is coaxially fixed to one end of the rotating shaft 71. The positioning gear 812 is slidably disposed on the connecting seat 6 and is used to mesh with the rotating gear 811. The sliding direction of the positioning gear 812 is parallel to the axial direction of the rotating shaft 71. The moving member 813 is disposed on the connecting seat 6 and is used to drive the positioning gear 812 to slide.

[0047] When the support roller 4 is in the first state and the second state, both the rotating gear 811 and the positioning gear 812 are in a meshing state.

[0048] When the support roller 4 rises to the lifting port 22 and it is necessary to release the fixing of the rotating frame 7, the positioning gear 812 is separated from the rotating gear 811 by the moving part 813, so that the rotating frame 7 can be automatically rotated after being guided by the guide plate 82.

[0049] When the support roller 4 is reset from the third state to the lifting port 22, and the rotating frame 7 needs to be fixed again, the moving part 813 drives the positioning gear 812 to mesh with the rotating gear 811, so that the rotating frame 7 can be fixed relative to the connecting seat 6, which improves the state switching efficiency of the rotating frame 7.

[0050] In both of the aforementioned situations where the rotating frame 7 is switched to a fixed state, the rotating frame 7 is in a vertical state. Therefore, it is not necessary to consider whether the rotating gear 811 can be aligned and directly meshed with the teeth of the positioning gear 812 after rotating with the rotating frame 7 via the rotating shaft.

[0051] Furthermore, when the support roller 4 is pressed against the upper part of the pipe in the third state, the positioning gear 812 does not need to mesh with the rotating gear 811. As long as the piston rod of the lifting cylinder 3 maintains an upward thrust, the support roller 4 can be pressed against the pipe. Therefore, the cooperation between the rotating gear 811 and the positioning gear 812 can not only achieve the stable fixation of the rotating frame 7, but also ensure the smooth switching of the state of the rotating frame 7.

[0052] likeFigure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The movable component 813 includes a movable rod 8131 and a movable cylinder 8132. The movable rod 8131 is slidably mounted on the connecting seat 6 along the axial direction of the rotating shaft 71, and the positioning gear 812 is coaxially fixed on the movable rod 8131; the movable cylinder 8132 is mounted on the connecting seat 6, and the piston rod of the movable cylinder 8132 is fixed to the movable rod 8131.

[0053] When it is necessary to switch the fixed or rotating state of the rotating frame 7, the moving cylinder 8132 is activated to make the moving rod 8131 move horizontally. The moving rod 8131 can then drive the positioning gear 812 to disengage from or re-engage with the rotating gear 811. The structure is simple and efficient.

[0054] Furthermore, the moving rod 8131 and the connecting seat 6 can be horizontally guided by a linear bearing or a guide sleeve to improve the sliding accuracy of the moving rod 8131, ensure that the positioning gear 812 always remains axially parallel to the rotating gear 811 during the sliding process, and further improve the state switching effect between the positioning gear 812 and the rotating gear 811.

[0055] like Figure 4 and Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The limiting component 81 also includes a ratchet 814 and a pawl 815; the ratchet 814 is coaxially fixed to the end of the rotating shaft 71 away from the rotating gear 811; the pawl 815 is rotatably mounted on the moving rod 8131 and is used to engage with the ratchet 814; when the pawl 815 engages with the ratchet 814, the rotating frame 7 can only rotate toward the pipe direction.

[0056] When the lifting cylinder 3 drives the rotating frame 7 to rise toward the lifting port 22, the moving part 813 drives the rotating gear 811 to separate from the positioning gear 812, and drives the pawl 815 to engage with the ratchet 814; when the lifting cylinder 3 drives the rotating frame 7 to rotate back into the lifting port 22, the moving part 813 drives the pawl 815 to separate from the ratchet 814, while the rotating gear 811 and the positioning gear 812 remain in a separated state.

[0057] Specifically, in this embodiment, the pawl 815 is equipped with a return spring 843 to ensure that the pawl 815 always has a preload force toward the ratchet 814, thereby further improving the engagement reliability.

[0058] The ratchet 814 and pawl 815 engage to achieve unidirectional locking of the rotating frame 7, allowing it to rotate only towards the pipe. This prevents the rotating frame 7 from rotating in the opposite direction due to external forces while automatically rotating under the guidance of the guide plate 82. When the support roller 4 presses against the upper part of the pipe, if the pipe sways, the reaction force on the support roller 4 will attempt to push the rotating frame 7 to rotate in the opposite direction. At this time, the unidirectional locking of the ratchet 814 and pawl 815 can instantly withstand the reaction force, engaging with the guide plate 82 to improve the stability of the rotating frame 7 and support roller 4 during rotation towards the pipe and after the support roller 4 presses against the pipe.

[0059] When the rotating frame 7 and the support roller 4 need to be reset into the receiving cavity, the moving part 813 drives the pawl 815 to separate from the ratchet, while the rotating gear 811 and the positioning gear 812 remain in a separated state, thus realizing the reverse reset of the rotating frame 7 and improving the operational stability of the limiting component 81.

[0060] Specifically, in this embodiment, when the support roller 4 is in the third state, the restriction component 81 is still entirely inside the receiving cavity, with only the support roller 4 and part of the rotating frame 7 extending out of the lifting port 22, so as to avoid external factors affecting the normal operation of the restriction component 81.

[0061] like Figure 7 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The translation assembly 5 includes a mounting frame 51, a bidirectional screw 52, ​​two guide rods 53, two threaded blocks 54, and a motor 55. The mounting frame 51 is fixed to the upper surface of the vehicle body 1 and is vertically slidably connected to the lifting seat 2, wherein the receiving cavity is used to receive the mounting frame 51.

[0062] The bidirectional screw 52 is horizontally rotatably connected within the mounting frame 51 and perpendicular to the axial direction of the arc-shaped groove 21; the bidirectional screw 52 is divided into two sections with opposite threads in its middle. Two guide rods 53 are fixed within the mounting frame 51 and parallel to the bidirectional screw 52, ​​with the two guide rods 53 located on opposite sides of the bidirectional screw 52.

[0063] Two threaded blocks 54 correspond one-to-one with two guide rods 53. The two threaded blocks 54 are threadedly connected to the threads of the bidirectional screw 52 with different directions of rotation, and the threaded blocks 54 are penetrated by the corresponding guide rods 53. The motor 55 is mounted on the outside of the mounting frame 51, and the output shaft of the motor 55 is coaxially fixed with the bidirectional screw 52. Among them, two lifting cylinders 3 correspond one-to-one with two threaded blocks 54, and the lifting cylinders 3 are vertically fixed on the corresponding threaded blocks 54.

[0064] When it is necessary to switch the support roller 4 from the first state to the third state, the motor 55 is started to make the bidirectional screw 52 rotate. The bidirectional screw 52 drives the two threaded blocks 54 to move in opposite directions. The two guide rods 53 guide the two threaded blocks 54 respectively, so that the two lifting cylinders 3 drive the two support rollers 4 to move to the bottom of the corresponding lifting port 22 respectively. The operation is convenient and the translation efficiency is high, thereby improving the state switching efficiency of the support roller 4.

[0065] like Figure 8 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning assembly 83 includes a positioning plate 831, a sliding plate 832, a positioning bolt 833, and a positioning nut 834. The positioning plate 831 is fixed to the lifting seat 2 and located on the side of the lifting seat 2 away from the arc-shaped groove 21. The sliding plate 832 is slidably disposed on the lifting seat 2 and faces the positioning plate 831; a guide plate 82 is located between the positioning plate 831 and the sliding plate 832. The positioning bolt 833 passes sequentially through the positioning plate 831, the guide plate 82, and the sliding plate 832. The positioning nut 834 is threaded onto the positioning bolt 833 and abuts against the outer side of the sliding plate 832.

[0066] When the angle of the guide plate 82 needs to be adjusted, loosening the positioning nut 834 will allow the sliding plate 832 to slide away from the guide plate 82, and the guide plate 82 can then rotate around the positioning bolt 833. After the angle of the guide plate 82 is adjusted, tightening the positioning nut 834 will clamp and fix the guide plate 82 between the sliding plate 832 and the positioning plate 831, making the operation convenient and efficient.

[0067] like Figure 8 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The rotary assembly 84 includes a fixed plate 841, a push plate 842, and a return spring 843. The fixed plate 841 is fixed on the lifting seat 2 and is located on the side of the lifting seat 2 near the arc-shaped groove 21. The push plate 842 is slidably disposed on the lifting seat 2 and faces the lifting port 22; the return spring 843 is connected between the fixed plate 841 and the push plate 842.

[0068] When the rotating frame 7 rises above the lifting port 22, it pushes the push plate 842 toward the fixed plate 841, and the reset spring 843 is compressed; when the rotating frame 7 descends to reset, the reset spring 843 drives the push plate 842 to push the rotating frame 7 to the vertical position.

[0069] Furthermore, the return spring 843 can be a cylindrical helical spring or a disc spring, whose elastic force changes linearly with the amount of compression and is adapted to the weight of the rotating frame 7.

[0070] When the rotating frame 7 and the support roller 4 rise to the lifting port 22, the push plate 842 is pushed towards the reset spring 843, and the reset spring 843 is compressed and stores elastic potential energy. When the rotating frame 7 and the support roller 4 descend to reset, the reset spring 843 releases potential energy to push the push plate 842 to reset smoothly. It can always generate a reset thrust on the rotating frame 7 during the rotation process, which improves the reset effect of the rotating frame 7 and the support roller 4.

[0071] Specifically, in this embodiment, the lifting cylinder 3, the moving cylinder 8132, and the pushing cylinder 93 are all electric cylinders, and a mobile power supply is provided on the vehicle body 1 to supply power to the electric cylinders and the motor 55.

[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
