Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, and in particular to a synchronous integrated hoisting device for boiler heating surfaces. Background Technology

[0002] As boiler equipment develops towards larger and more modular designs, the size and weight of boiler heating surface modules are constantly increasing. During boiler installation, it is usually necessary to hoist the prefabricated heating surface modules as a whole to the installation location and accurately position them. Since heating surface modules are typically composed of multiple tube panels, headers, and connecting structures, their overall size is large, and there are differences in internal piping layout and structural composition, resulting in uneven weight distribution. This can easily lead to problems such as shifting of the hoisting center of gravity, tilting of the module, and uneven stress on multiple lifting points during hoisting. Therefore, in the overall hoisting of large boiler heating surface modules, it is necessary to improve the adaptability of the hoisting device to heating surface modules with different structural forms to ensure the coordination and reliability of stress during the hoisting process.

[0003] In existing technologies, when hoisting boiler heating surface modules, multiple lifting points are typically used to directly connect the heating surface modules, with multiple lifting components sharing the weight of the heating surface modules. However, due to the large size and uneven weight distribution of the heating surface modules, it is difficult to maintain a consistent stress state among the lifting points. Some lifting points may bear large loads, causing the heating surface modules to tilt or shift during hoisting. At the same time, the positions of the lifting points in existing hoisting devices are usually fixed, making it difficult to make adaptive adjustments according to the structural dimensions and center of gravity position of different heating surface modules, affecting the balance and reliability of the hoisting process. Summary of the Invention

[0004] To address the problems of difficulty in adapting the lifting point positions during the existing boiler heating surface module hoisting process, uneven force distribution among multiple lifting points, and shift of the center of gravity of the hoisting system after lifting point adjustment, this application provides a synchronous integrated hoisting device for boiler heating surfaces.

[0005] The technical solution of the integrated synchronous hoisting device for boiler heating surfaces provided in this application is as follows: A synchronous integrated hoisting device for boiler heating surfaces includes a guide rail frame disposed on the top of the boiler. A moving mechanism is mounted on the guide rail frame, and a balancing mechanism is disposed below the moving mechanism. A first hoisting component and a second hoisting component are mounted on the moving mechanism. The first hoisting component is connected to the balancing mechanism to hoist the balancing mechanism. The second hoisting component passes through the connecting mechanism and connects to the boiler heating surface to hoist the boiler heating surface. The balancing mechanism includes an adjusting frame with a central hoisting point at its center. The adjusting frame also includes a hoisting point adjusting component and a counterweight adjusting component, both of which are slidably connected to the adjusting frame. At least four hoisting point adjusting components are provided, all arranged around the central hoisting point. The counterweight adjusting components are used to adjust the center of gravity position of the balancing mechanism, compensating for center of gravity shifts caused by changes in the position of the hoisting point adjusting components.

[0006] By adopting the above technical solution, a guide rail frame is set on the top of the boiler, and a moving mechanism is set on the guide rail frame, so that the hoisting device can move along a preset direction. The moving mechanism is equipped with a first hoisting component and a second hoisting component, which are used to hoist the balance adjustment mechanism and the boiler heating surface module, respectively. The first hoisting component supports the balance adjustment mechanism through the central hoisting point, so that the balance adjustment mechanism acts as a load transfer structure among multiple peripheral hoisting points, distributing the force on multiple hoisting action points and reducing the possibility of tilting or deformation of the heating surface module due to local force concentration. At the same time, by setting the hoisting point adjustment component and the counterweight adjustment component, the peripheral hoisting action points can be adjusted according to the heating surface modules of different specifications, and the counterweight adjustment component compensates for the center of gravity shift caused by the hoisting point adjustment, thereby improving the balance and adaptability during the hoisting process.

[0007] Optionally, the moving mechanism includes a first moving frame and a second moving frame, both of which are slidably connected to the guide rail frame. The first moving frame and the second moving frame are connected to a connecting plate, which connects the first moving frame and the second moving frame into a whole. The length directions of the first moving frame and the second moving frame are perpendicular to the length direction of the guide rail frame, and the length direction of the connecting plate is the same as the length direction of the guide rail frame. The first moving frame and the second moving frame can move along the length direction of the guide rail frame. A first winch is installed on the first movable frame. The hook of the first winch is connected to the central lifting point to lift the adjusting frame. A movable seat is installed on the second movable frame. A second winch is installed on the movable seat. The lifting rope of the second winch passes through the lifting point adjustment assembly and the connecting mechanism. The hook of the second winch is connected to the boiler heating surface to drive the boiler heating surface to rise and fall.

[0008] By adopting the above technical solution, the first and second moving frames are slidably connected to the guide rail frame respectively, and the first and second moving frames are connected by a connecting plate to form an integral structure, so that the first and second winches can move synchronously with the moving mechanism, improving the positional coordination between the various lifting components during the lifting process; wherein, the first winch is set on the first moving frame and is used to lift the center lifting point of the balance adjustment mechanism, and the second winch is set on the second moving frame and is used to lift the boiler heating surface module, so as to realize the synchronous cooperation between the balance adjustment mechanism and the heating surface module.

[0009] Optionally, the adjustment frame includes a transverse adjustment beam and a longitudinal adjustment beam, the transverse adjustment beam and the longitudinal adjustment beam are perpendicular to each other, and the transverse adjustment beam and the longitudinal adjustment beam together form a frame structure for installing the lifting point adjustment assembly and the counterweight adjustment assembly; The adjusting frame has a central positioning seat at its center, and a central lifting point is located on the central positioning seat. Four lifting point adjusting components are arranged around the central lifting point. Each lifting point adjusting component includes a first adjusting seat connected to a first adjusting rail. The first adjusting rail is slidably mounted on the transverse adjusting beam and can move along the length of the transverse adjusting beam. The first adjusting seat is slidably connected to the first adjusting rail and can move along the length of the first adjusting rail. A guide member is provided on the first adjusting seat for adjusting and guiding the lifting rope of the second winch.

[0010] By adopting the above technical solution, an adjustment frame composed of a transverse adjustment beam and a longitudinal adjustment beam is set, and a central positioning seat and a central lifting point are set at the center of the adjustment frame, so that the central lifting point serves as the reference bearing position of the balance adjustment mechanism; at the same time, through the cooperation of the first adjustment rail and the first adjustment seat, the guide component can be adjusted within the range of the adjustment frame, thereby changing the position of the peripheral lifting action point, so that the lifting device can be adapted to the heated surface modules of different sizes and lifting point arrangements.

[0011] Optionally, the guide includes a guide wheel and a first guide sleeve, wherein the center line of the rope outlet of the guide wheel coincides with the axis of the first guide sleeve, so that the hoisting rope of the second winch enters the first guide sleeve along the axial direction of the first guide sleeve, and the hoisting rope of the second winch is connected to the connecting mechanism after passing through the first guide sleeve.

[0012] By adopting the above technical solution, a guide component consisting of a guide wheel and a first guide sleeve is set up so that the hoisting rope of the second winch can change direction after passing through the guide wheel and enter the first guide sleeve. The first guide sleeve limits and guides the hoisting rope, reducing the swing of the hoisting rope during the lifting process and improving the stability during the hoisting process.

[0013] Optionally, a plurality of first guide rollers are provided inside the first guide sleeve. The plurality of first guide rollers are arranged together around the axis of the first guide sleeve, and the wheel surface of the first guide roller is perpendicular to the corresponding radial line of the first guide sleeve. That is, the rolling direction of the guide roller is adapted to the moving direction of the hoisting rope of the second winch.

[0014] By adopting the above technical solution, multiple first guide rollers are set inside the first guide sleeve and arranged around the axis of the first guide sleeve. This allows the lifting rope to be supported by rolling through the guide rollers during movement, reducing friction between the lifting rope and the inner wall of the sleeve, improving the smoothness of the lifting rope movement, and reducing the wear of the lifting rope.

[0015] Optionally, the counterweight adjustment assembly includes a counterweight slide rail, which is parallel to the longitudinal adjustment beam and slidably connected to the transverse adjustment beam. A counterweight slide block is slidably disposed on the counterweight slide rail, and a counterweight block is detachably connected to the counterweight slide block. The counterweight slide block can drive the counterweight block to move along the counterweight slide rail, and the counterweight slide rail can move along the length direction of the transverse adjustment beam to change the position of the counterweight block relative to the adjustment frame.

[0016] By adopting the above technical solution, a counterweight slide rail, a counterweight slide block, and a counterweight block are set up so that the counterweight block can be adjusted accordingly according to the position change of the lifting point adjustment component. At the same time, the counterweight slide rail can move along the transverse adjustment beam, and the counterweight block can move along the counterweight slide rail, thereby realizing multi-directional adjustment of the counterweight position, compensating for the center of gravity shift caused by the lifting point adjustment, and keeping the balance adjustment mechanism in a stable state.

[0017] Optionally, two counterweight slide rails and two counterweight blocks are provided. The two counterweight slide rails are respectively located on both sides of the central lifting point. Each counterweight slide rail is provided with a counterweight block. The two counterweight blocks can be connected to the transverse adjusting beam through corresponding counterweight slide seats and can move independently on the adjusting frame.

[0018] By adopting the above technical solution, two counterweights are set and placed on both sides of the central lifting point, so that the two counterweights can move independently and be adjusted separately according to the force changes in different directions of the adjustment frame, thereby improving the flexibility of counterweight adjustment and enabling the balance adjustment mechanism to adapt to changes in the center of gravity under different lifting point arrangements.

[0019] Optionally, the connecting mechanism includes two connecting frames, each of which is connected to two second adjusting seats. The two second adjusting seats, located on different connecting frames and on the same straight line, are connected to a second adjusting rail. The length direction of the second adjusting rail is perpendicular to the length direction of the connecting frame. The second adjusting seats can move along the second adjusting rail to adjust the lower connection position.

[0020] By adopting the above technical solution, a connection mechanism is formed by setting two connecting frames, a second adjusting rail, and a second adjusting seat, which enables multiple peripheral hoisting points to be connected to form an integral structure. The position of the second adjusting seat can be adjusted according to the actual connection position of the heated surface module, thereby improving the adaptability of the connection mechanism to heated surface modules of different specifications and reducing the offset caused by the connection structure during hoisting.

[0021] Optionally, a second guide sleeve is provided on the second adjusting seat. The second guide sleeve and the first guide sleeve are coaxially arranged and interconnected. The first guide sleeve and the second guide sleeve are detachably connected. The hoisting rope of the second winch passes through the first guide sleeve and the second guide sleeve in sequence. A plurality of second guide rollers are provided inside the second guide sleeve. The plurality of second guide rollers are arranged near the bottom of the second guide sleeve. The plurality of second guide rollers are in the same horizontal plane and are arranged around the central axis of the second guide sleeve. The wheel surface of the second guide roller is perpendicular to the corresponding diameter line of the second guide sleeve.

[0022] By adopting the above technical solution, a second guide sleeve is set on the second adjusting seat and the second guide sleeve is coaxially connected with the first guide sleeve, so that the first guide sleeve and the second guide sleeve together form a continuous guiding structure, which limits and guides the hoisting rope of the second winch in the vertical direction, thereby improving the stability of the hoisting rope during operation; at the same time, by setting a second guide roller, the friction between the hoisting rope and the second guide sleeve is reduced during the movement.

[0023] Optionally, the hook of the second winch is provided with an abutment plate, and the second adjusting seat is provided with an abutment plate. The abutment plate can move synchronously with the second adjusting seat. The abutment plate is located above the abutment plate. When the second winch drives the hook to move upward for lifting, the abutment plate can abut against the abutment plate. The lifting load generated by the second winch is transmitted to the second adjusting seat through the abutment plate, and then to the connecting frame.

[0024] By adopting the above technical solution, an abutment plate is set on the hook of the second winch and an abutment plate is set on the second adjusting seat. When the second winch is lifting, the lifting load can be transferred to the second adjusting seat through the abutment relationship between the abutment plate and the abutment plate, and further transferred to the connecting frame. This enables the connecting mechanism to bear the main lifting load, reduces the stress concentration caused by the lifting rope directly bearing all the load during the lifting process, and improves the load-bearing reliability of the connecting mechanism.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The first hoisting assembly, through the central hoisting point load-bearing balance adjustment mechanism, and using multiple hoisting point adjustment assemblies arranged around the central hoisting point to form multiple peripheral hoisting action points, allows the hoisting load to be transferred and distributed among multiple hoisting action points via the adjustment frame. At the same time, the hoisting point adjustment assemblies can adjust the position of the peripheral hoisting action points according to the structural dimensions of the boiler heating surface module and the arrangement of the hoisting points. The counterweight adjustment assembly can compensate for the center of gravity shift caused by changes in the position of the hoisting points, thereby improving the problem of uneven force distribution among multiple hoisting points, enhancing the device's adaptability to boiler heating surface modules of different specifications, and improving the balance and reliability during the hoisting process. 2. The first and second movable frames are connected by a connecting plate to form a whole, so that the first hoisting component, the second hoisting component and the balance adjustment mechanism can move synchronously along the guide rail frame, reduce the relative position deviation of each hoisting component during the movement, and improve the coordination during the transfer and installation positioning of the boiler heating surface module; 3. Through the cooperation of the first adjusting rail and the first adjusting seat, the guide can be adjusted in two intersecting directions, thereby changing the position of the peripheral hoisting action point, so that multiple hoisting action points can be adapted to boiler heating surface modules of different sizes, different center of gravity distributions and different connection positions. 4. A continuous lifting rope guiding channel is formed by the first guide sleeve and the second guide sleeve, and the lifting rope is guided by the first guide roller and the second guide roller, which can limit the lateral deviation of the lifting rope, reduce the friction and wear between the lifting rope and the inner wall of the sleeve, and improve the smoothness of the lifting rope's lifting and lowering operation. 5. By setting an abutment plate that can move synchronously with the second adjusting seat and an abutment disc set on the hook, the lifting load can be transferred to the second adjusting seat and the connecting frame through the abutment disc and the abutment plate, and the connecting mechanism connects multiple peripheral lifting points to form an integral load-bearing structure, thereby improving the load transfer capacity and load-bearing reliability of the connecting mechanism.

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] This application discloses a synchronous integrated hoisting device for boiler heating surfaces.

[0038] like Figure 1 and Figure 2 A synchronous integrated hoisting device for boiler heating surfaces includes a guide rail frame 1, a moving mechanism 2, a balancing adjustment mechanism 3, and a connecting mechanism 4. The guide rail frame 1 is installed on the top steel structure of the boiler and extends along the hoisting direction of the boiler heating surface module. The moving mechanism 2 is slidably mounted on the guide rail frame 1. The balancing adjustment mechanism 3 is connected below the moving mechanism 2. The connecting mechanism 4 is connected below the balancing adjustment mechanism 3. The boiler heating surface module is connected below the connecting mechanism 4, so that the moving mechanism 2, the balancing adjustment mechanism 3, the connecting mechanism 4, and the boiler heating surface module are arranged sequentially in the vertical direction.

[0039] The moving mechanism 2 is used to drive the balance adjustment mechanism 3 and the boiler heating surface module to move along the guide rail frame 1; the balance adjustment mechanism 3 is used to adjust the position of multiple lifting action points and compensate for the center of gravity offset caused by the adjustment of the lifting points; the connecting mechanism 4 is used to connect the boiler heating surface module and connect multiple lifting action points to form an integral load-bearing structure.

[0040] The moving mechanism 2 includes a first moving frame 21, two second moving frames 22, and a connecting plate 23. The first moving frame 21 is located between the two second moving frames 22, and both the first moving frame 21 and the second moving frame 22 are horizontally mounted on the guide rail frame 1 and slidably connected to the guide rail frame 1. The connecting plate 23 connects the first moving frame 21 and the two second moving frames 22, so that the first moving frame 21 and the two second moving frames 22 form an integral frame structure.

[0041] The guide rail frame 1 is a linear guide rail and has a rack along its length. Both the first moving frame 21 and the second moving frame 22 are equipped with drive motors. The output end of the drive motor is connected to a gear, which meshes with the rack. When the drive motor is working, the gear rolls along the rack, thereby driving the first moving frame 21, the second moving frame 22 and the connecting plate 23 to move synchronously along the guide rail frame 1.

[0042] Before hoisting, the distance between the first moving frame 21 and the second moving frame 22 is pre-adjusted according to the size of the boiler heating surface module and the arrangement of the hoisting points. The connecting plate 23 is perpendicular to the first moving frame 21 and the second moving frame 22 and is detachably connected to the first moving frame 21 and the second moving frame 22 respectively. By adjusting the connection position between the connecting plate 23 and the first moving frame 21 and the second moving frame 22, the distance between the first moving frame 21 and the second moving frame 22 can be adjusted. The connecting plate 23 connects the first moving frame 21 and the second moving frame 22 into a whole, ensuring that the first moving frame 21 and the second moving frame 22 can operate synchronously, reducing the deviation during the operation of the moving mechanism 2 and improving the overall moving stability.

[0043] The moving mechanism 2 is equipped with a first hoisting assembly 211 and a second hoisting assembly 2211. The first hoisting assembly 211 is mounted on the first moving frame 21 and is used to hoist the balance adjustment mechanism 3. The two second moving frames 22 are respectively equipped with second hoisting assemblies 2211 for hoisting the boiler heating surface module. The first hoisting assembly 211 includes a first winch 2111 for hoisting the balance adjustment mechanism 3. The second hoisting assembly 2211 includes a second winch 22111 for hoisting the boiler heating surface module.

[0044] The first winch 2111 is located at the center of the first moving frame 21 and directly above the center positioning seat 32. Its hook extends downward and connects to the center lifting point 321, so that the entire balance adjustment mechanism 3 is always lifted with the center lifting point 321 as the reference.

[0045] Each second movable frame 22 is equipped with two movable seats 221. The movable seats 221 are equipped with second winches 22111. The hoisting rope of the second winch 22111 passes through the balance adjustment mechanism 3 and the connecting mechanism 4 from top to bottom and is connected to the boiler heating surface module. During the hoisting process, the second winch 22111 provides the lifting power for the external hoisting points.

[0046] like Figures 2 to 4 The balance adjustment mechanism 3 includes an adjustment frame 31, which is located below the moving mechanism 2 and connected to the moving mechanism 2 via a first hoisting assembly 211. The adjustment frame 31 includes a transverse adjustment beam 311 and a longitudinal adjustment beam 312, which are perpendicularly connected to each other to form a frame structure. A central positioning seat 32 is provided at the intersection of the transverse adjustment beam 311 and the longitudinal adjustment beam 312. The central positioning seat 32 is located directly below the first winch 2111, and a central lifting point 321 is provided on the central positioning seat 32. The hook of the first winch 2111 is connected to the central lifting point 321, so that the entire balance adjustment mechanism 3 is always hoisted with the central lifting point 321 as the reference.

[0047] The balance adjustment mechanism 3 includes four lifting point adjustment components 34. The four lifting point adjustment components 34 are located around the central lifting point 321 and are arranged symmetrically around the central lifting point 321. Each lifting point adjustment component 34 can be moved and adjusted relative to the adjustment frame 31 to change the position of the corresponding lifting action point.

[0048] A first adjusting rail 33 is provided on the transverse adjusting beam 311. The lifting point adjusting assembly 34 includes a first adjusting seat 341 and a guide member 342. A rack is provided on the transverse adjusting beam 311, and a gear is provided on the first adjusting rail 33. The rack and the gear mesh with each other, so that the first adjusting rail 33 can move along the transverse adjusting beam 311. The gear is connected to a motor, and the motor drives the gear to rotate. When the motor drives the gear to rotate, the gear moves along the length direction of the rack, thereby driving the first adjusting rail 33 to move along the transverse adjusting beam 311.

[0049] A first adjusting seat 341 is slidably mounted on the first adjusting rail 33. A lead screw is mounted on the first adjusting rail 33, and a nut is mounted on the first adjusting seat 341. The lead screw and the nut are threadedly connected, allowing the first adjusting seat 341 to move along the first adjusting rail 33. One end of the lead screw is connected to a motor, which drives the lead screw to rotate. When the motor drives the lead screw to rotate, the nut moves along the lead screw, thereby driving the first adjusting seat 341 to move along the first adjusting rail 33.

[0050] like Figure 3 and Figure 5A guide member 342 is provided on the first adjusting seat 341. The guide member 342 includes a guide wheel 3421 and a first guide sleeve 3422. The guide wheel 3421 is disposed on the first adjusting seat 341, and the first guide sleeve 3422 is located below the guide wheel 3421 and is fixedly connected to the first adjusting seat 341. The rope outlet position of the guide wheel 3421 corresponds to the central axis of the first guide sleeve 3422, so that the hoisting rope of the second winch 22111 changes direction after passing through the guide wheel 3421. The first guide sleeve 3422 can then enter the first guide sleeve 3422 along the axial direction of the first guide sleeve 3422. The first guide sleeve 3422 is provided with a plurality of first guide rollers 3423. The plurality of first guide rollers 3423 are evenly arranged along the circumference of the first guide sleeve 3422 and are rotatably connected to the first guide sleeve 3422. The wheel surface of the first guide rollers 3423 contacts the lifting rope, so that the lifting rope can be supported by the first guide rollers 3423 when it moves along the first guide sleeve 3422.

[0051] The adjustment frame 31 is equipped with a counterweight adjustment assembly 35. There are two counterweight adjustment assemblies 35, located on both sides of the central lifting point 321. The counterweight adjustment assembly 35 includes a counterweight slide rail 351, a counterweight slide block 352, and a counterweight block 353. The counterweight slide rail 351 is arranged along the longitudinal adjustment beam 312 and is slidably connected to the transverse adjustment beam 311. A gear is provided on the counterweight slide rail 351. The gear meshes with a rack. The gear is connected to a drive motor. When the drive motor drives the gear to rotate, the gear moves along the rack, thereby driving the counterweight slide rail 351 to move along the transverse adjustment beam 311 to change the position of the counterweight slide rail 351 relative to the central lifting point 321.

[0052] A lead screw is provided on the counterweight slide rail 351, and the counterweight slide block 352 is slidably mounted on the counterweight slide rail 351. A nut is provided on the counterweight slide block 352, and the nut is threadedly connected to the lead screw. One end of the lead screw is connected to a drive motor. When the drive motor drives the lead screw to rotate, the nut moves along the lead screw, thereby driving the counterweight slide block 352 to move along the counterweight slide rail 351. The counterweight block 353 is detachably and fixedly connected to the counterweight slide block 352. When the counterweight slide block 352 moves, it drives the counterweight block 353 to move synchronously, so that the counterweight block 353 can be adjusted in position within the adjustment range formed by the transverse adjustment beam 311 and the longitudinal adjustment beam 312.

[0053] like Figure 6The system includes a control system 5, which comprises a center of gravity detection module 51 and a control module 52. The center of gravity detection module 51 is located at the central positioning seat 32 and the lifting point adjustment component 34, and is used to detect the force state and attitude changes at each position of the balance adjustment mechanism 3. Then, the control module 52 calculates the direction and amount of center of gravity offset based on the detection data. The center of gravity detection module 51 is connected to a signal transmission module 53, which transmits the data collected by the center of gravity detection module 51 to the control module 52. The control module 52 is electrically connected to the lifting point adjustment component 34 and the counterweight adjustment component 35, respectively. The control module 52 determines the direction and amount of center of gravity offset of the balance adjustment mechanism 3 based on the received center of gravity detection data and generates corresponding adjustment commands.

[0054] When a shift in the center of gravity of the balance adjustment mechanism 3 is detected, the control module 52 controls the motor in the lifting point adjustment assembly 34 to move the first adjustment rail 33 and the first adjustment seat 341 in the corresponding direction to adjust the position of the peripheral lifting action point. At the same time, the control module 52 controls the drive mechanism in the counterweight adjustment assembly 35 to move the counterweight slide rail 351 and the counterweight slide seat 352, thereby changing the position of the counterweight block 353 relative to the center lifting point 321. During the adjustment process, the center of gravity detection module 51 continuously feeds back the force state and attitude change data of the balance adjustment mechanism 3. The control module 52 adjusts the position of the lifting point adjustment assembly 34 and the counterweight adjustment assembly 35 in real time according to the feedback data until the balance adjustment mechanism 3 reaches the preset balance state.

[0055] like Figure 3 , Figure 7 and Figure 8 The connecting mechanism 4 is located below and connected to the balancing mechanism 3. The connecting mechanism 4 includes two connecting frames 41, which are arranged parallel to each other and located on both sides of the boiler heating surface module. A second adjusting rail 42 is provided between the two connecting frames 41, and the second adjusting rail 42 is arranged perpendicular to the connecting frames 41. Each connecting frame 41 is provided with two second adjusting seats 43, which are located at both ends of the length direction of the connecting frame 41. The two second adjusting seats 43 located on different connecting frames 41 and on the same straight line are connected to a second adjusting rail 42, so that the second adjusting seats 43 can move along the second adjusting rail 42.

[0056] A lead screw is provided on the second adjusting rail 42, and a nut is provided on the second adjusting seat 43. The nut is threadedly connected to the lead screw. A motor is connected to one end of the lead screw. When the motor drives the lead screw to rotate, the nut moves along the lead screw, thereby driving the second adjusting seat 43 to move along the second adjusting rail 42 to adjust the position of the second adjusting seat 43 relative to the connecting frame 41.

[0057] like Figure 9 A second guide sleeve 431 is provided on the second adjusting seat 43. The second guide sleeve 431 is located below the first guide sleeve 3422 and is coaxially sleeved with the first guide sleeve 3422. A connecting groove 34221 is opened on the outer circumferential surface of the first guide sleeve 3422, and a connecting hole 4311 is opened on the second guide sleeve 431. The connecting hole 4311 penetrates the cylinder wall of the second guide sleeve 431. The connecting groove 34221 can correspond to the connecting hole 4311. The first guide sleeve 3422 and the second guide sleeve 431 are bolted together through the connecting groove 34221 and the connecting hole 4311, so that the two guide sleeves form a continuous hoisting rope guiding channel.

[0058] The second guide sleeve 431 is provided with a plurality of second guide rollers 432. The plurality of second guide rollers 432 are arranged along the circumference of the second guide sleeve 431 and are located near the bottom of the second guide sleeve 431. The second guide rollers 432 are rotatably connected to the second guide sleeve 431. When the hoisting rope of the second winch 22111 passes through the second guide sleeve 431, it contacts the second guide rollers 432.

[0059] The hoisting rope of the second winch 22111 passes through the first guide sleeve 3422 and the second guide sleeve 431 in sequence and is connected to the boiler heating surface module. When the second winch 22111 is working, it drives the boiler heating surface module to rise and fall by winding and unwinding the hoisting rope.

[0060] The hook of the second winch 22111 is provided with an abutment plate 2212, which is fixedly connected to the outside of the hook. The second adjusting seat 43 is provided with an abutment plate 44, which is located above the abutment plate 2212 and is fixedly connected to the second adjusting seat 43.

[0061] When the second winch 22111 lifts, the hook moves upward with the lifting rope, causing the abutment plate 2212 to gradually approach the abutment plate 44. When the abutment plate 2212 contacts the abutment plate 44, the force generated by the hook can be transmitted through the abutment plate 2212 to the abutment plate 44, and further transmitted to the second adjusting seat 43 and the connecting frame 41.

[0062] The boiler heating surface module is connected to the lower part of the connecting mechanism 4. Multiple second adjustment seats 43 in the connecting mechanism 4 are respectively connected to the corresponding connection positions of the boiler heating surface module. By adjusting the position of the second adjustment seats 43, the connecting mechanism 4 can adapt to boiler heating surface modules of different sizes and different connection positions.

[0063] The implementation principle of this application embodiment is as follows: When hoisting the boiler heating surface module, firstly, the distance between the first moving frame 21 and the second moving frame 22 in the moving mechanism 2 is adjusted according to the size of the boiler heating surface module and the hoisting position. Then, the gear is driven by the drive motor to move along the rack, so that the moving mechanism 2 as a whole moves to the corresponding hoisting position. Subsequently, the balance adjustment mechanism 3 is suspended by the first winch 2111 connected to the center hoisting point 321. According to the hoisting position of the boiler heating surface module, the position of the first adjustment rail 33 and the first adjustment seat 341 is adjusted by the drive mechanism, so that the four hoisting point adjustment components 34 move to the corresponding hoisting position.

[0064] After the lifting point adjustment component 34 moves, the center of gravity detection module 51 detects the force state and attitude change of the balance adjustment mechanism 3, and feeds back the detection data to the control module 52 through the signal transmission module 53. The control module 52 determines the direction and amount of the center of gravity offset of the balance adjustment mechanism 3 based on the detection results, and controls the drive mechanism in the lifting point adjustment component 34 and the counterweight adjustment component 35 to move the first adjustment rail 33, the first adjustment seat 341, the counterweight slide rail 351 and the counterweight slide 352 to the corresponding positions to automatically adjust the balance adjustment mechanism 3. During the adjustment process, the center of gravity detection module 51 continuously detects and provides feedback until the balance adjustment mechanism 3 reaches the preset balance state.

[0065] After the balance adjustment mechanism 3 is adjusted, the hoisting rope of the second winch 22111 is passed through the first guide sleeve 3422 and the second guide sleeve 431 in sequence and connected to the boiler heating surface module. The second winch 22111 drives the boiler heating surface module to be lifted by winding the hoisting rope. During the lifting process, the abutment plate 2212 contacts the abutment plate 44, so that the force generated by the second winch 22111 can be transmitted to the connecting mechanism 4 through the abutment plate 2212 and the abutment plate 44. At the same time, the hoisting rope continuously provides the lifting effect, so that the boiler heating surface module is kept in a stable hoisting state.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
