Description

Technical Field

[0001] This invention belongs to the field of construction equipment for steel structures, and relates to a collaborative control system and control method for unloading large-span irregular roofs. Background Technology

[0002] Large-span irregular roofs are widely used in large stadiums, convention centers and other building projects. These roofs have a large overall span and a wavy curved shape, and the structural stress is complex. During the on-site installation and unloading operations, special support equipment is needed to complete the roof posture adjustment, stress balance detection and assisted disassembly and assembly procedures.

[0003] Currently, the supporting devices used for the installation and unloading of such roofs struggle to simultaneously collect and verify the stress state at various points on the roof surface during the overall lifting and positioning of the roof. When there are differences in stress distribution across different areas of the roof's curved surface, timely attitude calibration is impossible. Furthermore, the connection structure between the roof and supporting components often uses a fixed docking method. When the roof's curved surface causes even slight angular displacement, the connection points are prone to rigid compression, resulting in insufficient structural adaptability.

[0004] Meanwhile, after the roof installation is completed, the separation process between the support device and the roof requires the step-by-step alignment and release of multiple sets of connectors. The linkage between the various limiting and positioning structures is weak, and the overall synchronization of the device's movements needs to be improved. Some support structures can only provide basic support and cannot perform multi-point stress monitoring based on the roof's curved surface characteristics, making it difficult to meet the operational requirements of high-precision installation and safe unloading of large-span negative curvature roofs. Summary of the Invention

[0005] In view of this, in order to solve the problems that the existing supporting equipment for roof installation and unloading is difficult to adapt to the structural form of large-span negative curvature roofs, and that there are problems such as insufficient force monitoring and poor connection of limit disassembly actions, which make it difficult to meet the requirements of high-precision installation and safe unloading of large-span negative curvature roofs, the present invention provides a collaborative control system and control method for unloading large-span irregular roofs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A collaborative control system for unloading a large-span irregular roof includes two corrugated main frames. Two mounting seats are fixedly installed at both ends of the two corrugated main frames. Two symmetrically arranged extension seats are fixedly installed on the side of the mounting seats away from the corrugated main frames. Two symmetrically arranged reinforcing rods are fixedly installed between the two mounting seats. A common connecting horizontal plate is fixedly installed between the two reinforcing rods.

[0008] The lower plate and the upper plate are arranged above the lower plate and parallel to each other. Multiple mounting flanges are fixedly installed on the side of the lower plate and the upper plate that are close to each other. The same support column is fixedly installed between two corresponding mounting flanges. Multiple mounting holes are opened inside the mounting flanges. A lower support is fixedly installed on the top of the upper plate. A connecting ball is movably embedded inside the lower support. An upper support is fixedly installed on the top of the connecting ball. The top of the upper support is connected to the connecting cross plate through a connecting component.

[0009] A fixed cross plate is fixedly sleeved on the outer wall of the upper support, and limiting components for limiting the connection cross plate are provided on both sides of the fixed cross plate.

[0010] The top of the lower plate is equipped with a disassembly assembly for detaching the connection between the connecting cross plate and the upper support.

[0011] Furthermore, the connecting assembly includes multiple threaded holes inside the upper support, one of which has a threaded section through its internal thread. A limit block I is fixedly installed at the bottom of the threaded section, and a vertical rod is fixedly installed at the top of the threaded section. Two symmetrically arranged positioning holes are opened inside the vertical rod. Side holes are opened on both sides of the connecting horizontal plate, and the top of the vertical rod extends into the interior of the side holes.

[0012] Furthermore, the limiting component includes a rectangular vertical hole inside the fixed horizontal plate. A limiting vertical plate is fixedly installed inside the rectangular vertical hole. Multiple limiting protrusions are fixedly installed on both sides of the limiting vertical plate. A guide rod slides through the limiting vertical plate. An insert is fixedly installed at one end of the guide rod, and a limiting block II is fixedly installed at the other end of the guide rod. A tension spring is provided between one side of the insert and one side of the limiting vertical plate. An arc-shaped groove is provided on one side of the insert. Two symmetrically arranged positioning rods are fixedly installed on one side of the arc-shaped groove. The positioning rods are used in conjunction with the positioning holes.

[0013] Furthermore, both sides of the rectangular vertical hole are provided with interconnected side sliding holes. A sliding block I is slidably connected inside the rectangular vertical hole. A connecting plate I is fixedly installed on the top of the sliding block I. One side of the connecting plate I is fixedly connected to one side of the insert block. The same compression spring is provided between one side of the sliding block I and one side of the inner wall of the rectangular vertical hole.

[0014] Furthermore, sliding blocks 2 are fixedly installed on both sides of sliding block I. A connecting strip rod is fixedly installed on one end of sliding block II. The same side sliding block is fixedly installed on one end of the two connecting strip rods. A limiting top plate is fixedly installed on the top of the side sliding block. The limiting top plate is used in conjunction with the extension seat.

[0015] Furthermore, the disassembly assembly includes an electric push rod II fixedly installed on the top of the lower plate. The piston rod of the electric push rod II is fixedly installed on a support plate. Four I-shaped blocks are fixedly installed on the top of the support plate. Four I-shaped holes are opened inside the upper plate. The tops of two I-shaped blocks on one side slide through the corresponding I-shaped holes and are fixedly installed with the same connecting plate II. A supporting vertical plate is fixedly installed on the top of the connecting plate II. A rotating shaft is rotatably connected to the top of the supporting vertical plate. A limiting block is fixedly sleeved on the outer wall of the rotating shaft. The limiting block is engaged between the limiting vertical plate and the connecting plate I.

[0016] Furthermore, two mounting plates are fixedly installed at both ends of the two connecting plates II. Multiple threaded rods pass through the internal threads of the mounting plates. A spherical block is fixedly installed on the top of the threaded rod, and a pressure sensor is fixedly embedded on the top of the spherical block. An adjusting block is fixedly installed on the bottom of the threaded rod. Two symmetrically arranged strip-shaped clearance holes are opened inside the upper plate. The strip-shaped clearance holes are used in conjunction with the multiple threaded rods.

[0017] Furthermore, hooks are fixedly installed at the four corners of the top of the upper plate, and electric push rods I are fixedly installed at the four corners of the top of the upper plate. The piston rod of electric push rod I abuts against the bottom of the mounting base.

[0018] A collaborative control method for unloading large-span irregular-shaped roofs, employing the collaborative control system for unloading large-span irregular-shaped roofs as described above, includes the following steps:

[0019] S1. Use hoisting equipment to attach the hoisting rope to the hook and move the entire device upwards until the wavy main frame is initially leveled.

[0020] S2. Start the electric push rod II to move the support plate upward, causing the I-shaped block and connecting plate II to rise. Multiple spherical blocks on the mounting plate abut against the arc surface of the corrugated main frame. Pressure data is collected by the pressure sensor to determine whether the corrugated main frame is in a stable state.

[0021] S3. After the corrugated main frame and the limiting top plate have reached a stable contact, start multiple electric push rods I to lift the four corners upward and provide stable support, thus completing the installation of the corrugated main frame and external components.

[0022] S4. Start the electric push rod II to move its piston rod down to the lowest point, which will drive the support vertical plate and the limit block to move down, thereby releasing the clamping of the limit vertical plate and the connecting plate I;

[0023] S5. The compression spring pushes the sliding block I to reset, causing the insert block and positioning rod to move laterally, so that the positioning rod disengages from the positioning hole and the insert block disengages from the side hole, thereby causing the vertical rod to disengage from the side hole and disconnecting the connection between the upper support and the connecting horizontal plate.

[0024] S6. The entire device is lowered using hoisting equipment to complete the unloading and coordinated control.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. The large-span irregular roof unloading collaborative control system disclosed in this invention adopts a combined structure of lower support, connecting universal ball joint and upper support, relying on the universal rotation characteristics to adapt to the curved surface deformation and multi-angle tilt of the wave-shaped negative curvature roof. During the roof lifting and attitude fine adjustment process, the support points can adapt to the roof angle changes in real time, avoiding local stress concentration caused by rigid contact, allowing the vertical load to be evenly transmitted to the support columns, and improving the stress uniformity of the overall load-bearing system.

[0027] 2. The collaborative control system for unloading large-span irregular roofs disclosed in this invention uses multiple sets of spherical blocks and pressure sensors deployed at multiple points along the curved surface of the roof to simultaneously collect real-time pressure parameters at each contact point. Based on the feedback of pressure data across the entire area, operators can accurately determine the overall balance of the roof, perform targeted attitude corrections, ensure the positioning accuracy of large-span roofs, and meet the high-precision construction requirements of building steel structures.

[0028] 3. The collaborative control system for unloading large-span irregular roofs disclosed in this invention has an extension seat and a limiting top plate working together to form a lateral constraint structure during the roof lifting and initial leveling stages. This effectively controls the horizontal displacement of the roof, reduces the structural sway, and ensures the continuity and accuracy of pressure sensor data acquisition while creating favorable working conditions for subsequent alignment and installation processes.

[0029] 4. The collaborative control system for unloading large-span irregular roofs disclosed in this invention uses threaded holes, vertical rods, positioning holes, and positioning rods to form a combined positioning structure, which, together with tension springs and compression springs, achieves automatic locking and resetting of the positioning components. During the hoisting and transportation of the device and the temporary support stage of the roof, it can stably lock the relative position of the connecting horizontal plate and the upper support, ensuring a firm connection between the roof and the support body, and improving the overall stability of the transportation and temporary support process.

[0030] 5. The large-span irregular roof unloading collaborative control system disclosed in this invention has a limiting block movably mounted on the top of the supporting vertical plate, which has its own rotation and small displacement space, and can cooperate with the limiting vertical plate and connecting plate I to adapt to the slight tilt of the roof in multiple directions. This structure can accommodate normal deformation of the roof without the limiting constraint failing, thus broadening the applicable working conditions of the limiting structure.

[0031] 6. The collaborative control system for unloading large-span irregular roofs disclosed in this invention uses the electric push rod II as the core driving component. This push rod can synchronously drive the I-shaped block, connecting plate II, and the entire set of limiting and positioning components to move in an orderly manner, achieving integrated linkage operation of lateral limit release and point positioning separation. Each mechanical structure completes its actions according to a preset sequence, simplifying the separation process of the support system after the roof installation is completed, and making the unloading operation process more seamless.

[0032] 7. The collaborative control system for unloading large-span irregular roofs disclosed in this invention uses upper and lower plates and multiple sets of support columns assembled and connected via mounting flanges. The modular combination ensures balanced stress distribution and a regular structure on the load-bearing body, enabling stable bearing of the overall load of the large-span roof. Combined with hooks at the four corners of the upper plate, it can be adapted to conventional hoisting equipment for lifting and moving the entire device, adapting to various hoisting operation scenarios on construction sites.

[0033] 8. The collaborative control system for unloading large-span irregular roofs disclosed in this invention integrates multiple functions such as load-bearing support, attitude limiting, pressure monitoring, adaptive self-alignment, and linkage unloading. One set of equipment can cover the entire construction process of lifting, leveling, installing, and unloading large-span irregular roofs. The various functional modules work together to improve the efficiency of the connection between various processes in the on-site construction of the roof.

[0045] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0046] like Figure 2 , 3 The large-span irregular roof unloading collaborative control system shown is applied to... Figure 1The large-span irregular roof structure shown includes two sets of corrugated main frames 1 arranged opposite each other. Mounting seats 10 are fixed to both ends of each corrugated main frame 1. On the side of each mounting seat 10 furthest from the corrugated main frame 1, two sets of symmetrically distributed extension seats 9 are fixed. Two symmetrically arranged reinforcing rods 8 are erected between the two sets of mounting seats 10, and a connecting horizontal plate 7 is fixed together at the middle of the two reinforcing rods 8. The entire structure relies on the corrugated main frames 1 to support the large-span negative curvature roof to be constructed. The mounting seats 10 and extension seats 9, as lateral force-bearing components, together with the reinforcing rods 8 and connecting horizontal plate 7, form an integrated frame that can evenly distribute the roof's forces to all components.

[0047] Furthermore, a lower flatbed 6 and an upper flatbed 12 are set up on site, such as... Figure 4 As shown, the upper plate 12 is arranged parallel to the lower plate 6 directly above it. Multiple sets of mounting flanges 18 are fixed to the opposite surfaces of the lower plate 6 and the upper plate 12. A common support column 4 is assembled between two sets of mounting flanges 18 that are vertically or horizontally aligned. Multiple mounting holes 5 are formed on the disc of each mounting flange 18, and fasteners pass through these holes 5 to complete the fixing assembly of the mounting flange 18 to the corresponding plate surface. Preferably, the support column 4 is made of alloy structural steel, capable of withstanding the vertical load transmitted by the large-span roof for a long period, ensuring the stability of the overall load-bearing structure. A lower support 17 is fixed to the top surface of the upper plate 12, as shown... Figure 5 As shown, a movably fitted universal ball joint 19 is installed inside the lower support 17. The universal ball joint 19 can rotate freely inside the cavity of the lower support 17. The upper support 22 is fixed to the top of the universal ball joint 19. The upper support 22 is assembled with the upper connecting plate 7 through the connecting assembly. Preferably, the universal ball joint 19 is made of heat-treated steel, and the rotating contact surface has good wear resistance, which can adapt to multi-angle posture changes over a long period of time. Based on this, when the corrugated main frame 1 tilts with the roof, the universal ball joint 19 will rotate synchronously, keeping the connection between the upper support 22 and the connecting plate 7 stable and avoiding additional stress caused by rigid contact.

[0048] Specifically, the connecting assembly includes multiple threaded holes 24 inside the upper support 22. A threaded section 30 is screwed into one of the threaded holes 24. A limiting block I 29 is fixed to the bottom end of the threaded section 30, preventing the threaded section 30 from completely unscrewing out of the threaded hole 24. A vertical rod 35 is vertically fixed to the top end of the threaded section 30. Two symmetrically distributed positioning holes 38 are formed inside the rod 35. Side holes 23 are formed on both sides of the connecting horizontal plate 7. The upper end of the vertical rod 35 extends into the internal space of the side holes 23. During the upward movement of the entire device using external hoisting equipment, the vertical rod 35 extends into the side holes 23, limiting the relative displacement between the connecting horizontal plate 7 and the upper support 22, preventing the corrugated main frame 1 from detaching during transport.

[0049] Furthermore, the outer wall of the upper support 22 is fixedly fitted with a horizontal plate 21, and limiting components for cooperating with and connecting the horizontal plate 7 are respectively arranged on the left and right sides of the fixed horizontal plate 21. Figure 6 As shown, the limiting assembly includes a rectangular vertical hole 32 opened inside the fixed horizontal plate 21. The inner cavity of the rectangular vertical hole 32 is fixed to the limiting vertical plate 26. Multiple limiting protrusions 33 are integrally formed on both sides of the limiting vertical plate 26. The limiting protrusions 33 can prevent the fixed limiting vertical plate 26 from shaking up and down. A guide rod 37 is installed inside the plate of the limiting vertical plate 26. The guide rod 37 can slide along the length direction of the limiting vertical plate 26. A plug block 25 is fixed at one end of the guide rod 37 facing the vertical rod 35, and a limiting block II 41 is fixed at the other end of the guide rod 37. A tension spring 36 is connected between the side of the plug block 25 and the plate surface of the limiting vertical plate 26. An arc-shaped groove 40 is opened on the side of the plug block 25 facing the vertical rod 35. Two symmetrically arranged positioning rods 39 are fixed on the groove wall of the arc-shaped groove 40. The positioning rods 39 and the positioning holes 38 on the surface of the vertical rod 35 form a plug-in fit. The tension spring 36 will continuously apply tension to the insert block 25, which will keep the positioning rod 39 inserted into the positioning hole 38 under normal conditions, thereby reinforcing the relative position of the vertical rod 35 and the insert block 25 and improving the tightness of the overall connection.

[0050] Based on this, side sliding holes 31 connecting to the outside are respectively opened on both sides of the rectangular vertical hole 32. A sliding block I 43 is installed inside the rectangular vertical hole 32, and the sliding block I 43 can slide along the vertical space of the rectangular vertical hole 32. A connecting plate I 42 is fixedly attached to the top surface of the sliding block I 43. The side of the connecting plate I 42 away from the sliding block I 43 is fixedly connected to the insert block 25. A compression spring 34 is installed between the side wall of the sliding block I 43 and the inner side wall of the rectangular vertical hole 32. The compression spring 34 is in a compressed state under normal conditions, which can generate a continuous thrust on the sliding block I 43. When the external constraint is released, the elastic force of the compression spring 34 will push the sliding block I 43 to complete the position reset, causing the matching insert block 25 to move synchronously. Figure 7 As shown, sliding blocks II 44 are fixed to the outer walls of both sides of sliding block I 43. A strip rod 45 is fixed to the outer end of each sliding block II 44. The outer ends of the two connecting strip rods 45 on the same side are used to fix the side sliding block 13. A limiting top plate 14 is fixed to the top surface of the side sliding block 13, and the surface of the limiting top plate 14 is in contact with the side of the extension seat 9. During the lifting and initial leveling stage of the roof, the limiting top plate 14 abuts against the surface of the extension seat 9, which can constrain the horizontal displacement of the wave-shaped main frame 1, reduce the overall sway amplitude of the structure, and keep the roof in a stable posture.

[0051] Furthermore, disassembly components are arranged on the top surface area of ​​the lower plate 6, such as... Figure 8As shown, the disassembly assembly includes an electric push rod II 11 fixed to the top surface of the lower plate 6. The piston rod of the electric push rod II 11 is fixed to a support plate 50. Four sets of I-shaped blocks 49 are evenly fixed to the top surface of the support plate 50. Four I-shaped holes 15 are correspondingly opened inside the upper plate 12. Two sets of I-shaped blocks 49 on the same side pass upward through the corresponding I-shaped holes 15. The tops of the two sets of I-shaped blocks 49 are jointly fixed to a connecting plate II 48. A support vertical plate 20 is vertically fixed to the top surface of the connecting plate II 48. A rotating shaft 28 is rotatably assembled at the top of the support vertical plate 20. A limiting block 27 is fixed to the outer wall of the rotating shaft 28. The limiting block 27 is engaged in the gap between the limiting vertical plate 26 and the connecting plate I 42. The overall width of the limiting block 27 and the supporting vertical plate 20 is smaller than the internal width of the rectangular vertical hole 32. When the wave-shaped main frame 1 tilts slightly in different directions, the limiting block 27 can rotate by relying on the rotating shaft 28, or it can make a small displacement by using the reserved gap to adapt to the changes in the posture of the roof, while continuously maintaining the positional constraint on the limiting vertical plate 26 and the connecting plate I 42.

[0052] Furthermore, two plates 51 are fixedly installed at both ends of the connecting plate II 48. Multiple threaded rods 47 are vertically inserted inside each mounting plate 51, forming a threaded fit between the threaded rods 47 and the mounting plate 51. A spherical block 46 is fixed to the top of the threaded rod 47, and a pressure sensor 52 is embedded in the top of the spherical block 46. An adjusting block 53 is fixed to the bottom of the threaded rod 47. Two sets of symmetrically arranged strip-shaped clearance holes 16 are also opened inside the upper plate 12. The rods of the threaded rods 47 pass through the strip-shaped clearance holes 16 and can move slightly within the holes. Operators can rotate the adjusting block 53 to rotate the threaded rods 47, thereby adjusting the overall height of the spherical block 46 so that the spherical surface of the spherical block 46 conforms to the curved contour of the wave-shaped main frame 1. The pressure sensor 52 collects the pressure values ​​at the contact points in real time. By combining the data returned by multiple pressure sensors 52, on-site personnel can determine the overall balance of the roof and carry out subsequent attitude correction work.

[0053] Based on this, hooks 3 are fixed to the four corners of the top surface of the upper plate 12. The hooks 3 can be directly attached to the hoisting ropes of the on-site hoisting equipment. The entire device relies on the hoisting equipment to complete the lifting and position transfer. The support column 4 below, together with the upper and lower plates, forms a complete load-bearing system, which can stably transfer various loads generated by the roof and ensure the safety of transportation and construction. Multiple sets of electric push rods I2 are also set up on site. The electric push rods I2 are arranged under the four corners of the wave-shaped main frame 1. When the pressure data collected by the pressure sensor 52 tends to be consistent, indicating that the roof posture has been stabilized, the piston rod of the electric push rod I2 gradually extends outward, lifting the four corners of the wave-shaped main frame 1 from the bottom, completing the final calibration and temporary support of the roof posture.

[0054] After the roof and surrounding building structure of the wave-shaped main frame 1 are installed, the electric push rod II 11 is activated. The piston rod of the electric push rod II 11 drives the support plate 50 to move downward as a whole. The support plate 50 simultaneously drives the I-shaped block 49, the connecting plate II 48, and the support vertical plate 20 to move downward. The limiting block 27 then disengages from the gap between the limiting vertical plate 26 and the connecting plate I 42. The sliding block I 43, which was originally blocked by the limiting block 27, loses its external constraint and moves laterally under the thrust of the compression spring 34. The sliding block I 43 then drives the sliding block II 44, the connecting strip rod 45, and the side sliding block 13 to move in sequence. The limiting top plate 14 moves synchronously with the side sliding block 13 and gradually disengages from the side of the extension seat 9, releasing the lateral constraint on the wave-shaped main frame 1. Simultaneously, connecting plate I42 drives the insert 25 to move synchronously. The insert 25 overcomes the tension of the tension spring 36 and generates displacement. The positioning rod 39 is gradually pulled out from the positioning hole 38 on the surface of the vertical rod 35. After the insert 25 completely leaves the side hole 23 on the side of the connecting horizontal plate 7, the vertical rod 35 is no longer obstructed by the structure, and the connection between the connecting horizontal plate 7 and the upper support 22 is completely released. After completing the above actions, the hoisting equipment slowly lowers the entire support device, thus completing the entire process of unloading the roof.

[0055] Dust covers are installed on the outside of exposed sliding parts such as guide rod 37, sliding block I 43, and I-shaped block 49. Dustproof sealing strips are installed at the openings of the side sliding holes 31 and I-shaped holes 15 to prevent dust and debris from entering the sliding mating area. Various sliding mating parts inside this device need to be cleaned and lubricated regularly to ensure smooth sliding of the parts.

[0056] When the large-span irregular roof unloading collaborative control system is in use, multiple hoisting ropes are hung on hooks 3 through hoisting equipment, and the entire device is moved upward. In the initial state, the connecting horizontal plate 7 and the upper support 22 are connected and cannot be separated, thus ensuring that the wave-shaped main frame 1 will not fall when it moves upward, ensuring the safety of the device.

[0057] After the device rises to the appropriate position, the wave-shaped main frame 1 is already in a preliminary leveling state. The electric push rod II 11 is activated. The piston rod of the electric push rod II 11 drives the support plate 50 to move upward. The support plate 50 drives multiple I-shaped blocks 49 to move upward. The multiple I-shaped blocks 49 drive the connecting plate II 48 to move upward. The connecting plate II 48 drives the mounting plates 51 on both sides to rise. The interior of the mounting plate 51 is pre-adjusted to the appropriate height according to the curvature of the roof. At this time, the multiple spherical blocks 46 abut against the arc surface of the wave-shaped main frame 1, and the pressure is collected by multiple pressure sensors 52. If the pressure is consistent, it can be indicated that the wave-shaped main frame 1 is currently in a suitable installation position.

[0058] If the pressure collected by multiple pressure sensors 52 is inconsistent and fluctuates, it proves that the wave-shaped main frame 1 is still in a swaying state. The installation status of the wave-shaped main frame 1 can be understood through the limiting top plates 14 on both sides. After the wave-shaped main frame 1 is stabilized by contacting the limiting top plates 14, the multiple electric push rods I2 at the four corners can be activated. The piston rods of the multiple electric push rods I2 gradually extend, thereby lifting the four corners of the wave-shaped main frame 1 upward. After the lifting is completed, the wave-shaped main frame 1 is stably supported.

[0059] After adjustment, the wave-shaped main frame 1 and the already installed components can be installed. After installation, the device below needs to be disassembled. In the initial leveling state, the two sides of the limiting block 27 abut against the limiting vertical plate 26 and the connecting plate I 42 respectively, to prevent the connecting plate I 42 and the limiting vertical plate 26 from getting close. When the wave-shaped main frame 1 tilts in this direction, the limiting block 27 can rotate around the rotating shaft 28 to adapt. The width of the limiting block 27 and the supporting vertical plate 20 is less than the width of the rectangular vertical hole 32, so that when the wave-shaped main frame 1 tilts in another direction, there is space for adaptation. At this time, the electric push rod II11 is activated, causing the piston rod of the electric push rod II11 to move down. After the piston rod of the electric push rod II11 moves down to the lowest point, the connecting plate II48 will drive the supporting vertical plate 20 and the limiting block 27 to move down. The limiting block 27 moves out from the inside of the limiting vertical plate 26 and the connecting plate I42. At this time, the sliding block I43 is reset under the elastic force of the compression spring 34. The sliding block I43 drives the sliding block II44 to move laterally. The sliding block II44 drives the connecting strip rod 45 to move laterally. The connecting strip rod 45 drives the side sliding block 13 to move laterally. The side sliding block 13 drives the limiting top plate 14 to move. At this time, the limiting top plate 14 moves out from the side of the extension seat 9, which is convenient for subsequent disassembly.

[0060] Simultaneously, sliding block I43 drives connecting plate I42 to move laterally, and connecting plate I42 drives insert block 25 to move laterally. The tension of tension spring 36 and the guidance of guide rod 37 ensure the stability of insert block 25's movement. Insert block 25 drives positioning rod 39 to move laterally. Positioning rod 39 moves out of the positioning hole 38, and insert block 25 moves out of the side hole 23. At this time, there is no longer any obstruction when vertical rod 35 moves out of the side hole 23. At this time, upper support 22 and connecting horizontal plate 7 are no longer connected, realizing the disengagement process. The device is lowered by hoisting equipment to complete the operation process.

[0061] It also includes a controller, which is electrically connected to electric actuator I2, electric actuator II11, and pressure sensor 52 respectively; after the description of the corresponding electrical components in the specific implementation, the following is added: This device is equipped with a controller, which receives the pressure data transmitted by pressure sensor 52 and controls electric actuator I2 and electric actuator II11 to complete start-stop and stroke extension actions according to the preset control program.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
