Description

Technical Field

[0001] This invention relates to the field of steam turbine rotor maintenance technology, and in particular to a non-destructive disassembly tool for steam turbine rotor coupling connecting bolts. Background Technology

[0002] The turbine rotor coupling is a key component connecting the turbine rotor and the generator rotor. Its main function is to transmit power from the turbine rotor to the generator rotor, thereby enabling the generator to operate. The coupling is typically made of metal and must be able to withstand high-speed rotation and high torque. It must possess good wear resistance, high strength, and stable transmission performance to ensure effective transmission between the turbine and the generator.

[0003] Currently, all rotors in the main turbine generator sets are rigidly connected by bolts using couplings. The clearance between these bolts and the coupling holes is only 0.04-0.08mm. During long-term operation of the unit: 1. It has to withstand very large shear stress, causing the clearance to disappear; 2. Since the unit operates at a speed of 3000 rpm, the heat generated by the blower at the coupling location will cause the surrounding lubricating oil to atomize, further aggravating the disappearance of the clearance; Finally, when disassembling the coupling bolts during unit maintenance, disassembly is very difficult due to excessive tightening force, especially the connecting bolts of the coupling between the generator rotor and the low-pressure rotor, which are about 1000mm long, making disassembly particularly labor-intensive and time-consuming.

[0004] Currently, mechanical disassembly is typically used to remove coupling bolts one by one. However, a coupling usually has four to six bolts, and with existing technology, they need to be removed one by one, resulting in a significant waste of time. Therefore, a disassembly machine that can remove multiple bolts at once is proposed, thereby improving disassembly efficiency.

[0005] Chinese patent publication number CN116475977A discloses a non-destructive disassembly tool for turbine rotor coupling connecting bolts. It includes a bolt and nut disassembly unit, a clamping and fixing unit, and a drive transmission unit. The bolt and nut disassembly unit includes a mounting plate with a side plate movably mounted on its side wall. A limit slider is slidably mounted on the surface of the side plate. The clamping and fixing unit includes a sleeve with a locking block slidably mounted inside. The drive transmission unit includes a rotating shaft with a first gear fixedly mounted at its end. By incorporating these components, the bolt and nut disassembly unit disassembles the bolts. When the disassembly position of the bolt and nut disassembly unit is adjusted, the clamping and fixing unit moves. The drive transmission unit automatically adjusts its transmission method based on the change in the position of the bolt and nut disassembly unit, thus ensuring that the drive transmission unit can drive the bolt and nut disassembly unit to operate.

[0006] Although the aforementioned device can disassemble multiple bolts simultaneously during use, it is clearly inconvenient to flexibly adjust the entire device during actual use. Specifically, the bolts of the automotive rotor coupling are not easily adjustable, and only a single model and specification of rotor coupling can be disassembled and assembled during use. Although the bolts on the top of different models of rotor couplings are arranged in the same way, such as in a rectangular arrangement, the overall bolt spacing varies depending on the size of the coupling. Therefore, the overall adaptability of the aforementioned device is poor, and it needs to be improved. Summary of the Invention

[0007] The purpose of this invention is to provide a non-destructive disassembly tool for turbine rotor coupling connecting bolts, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides a non-destructive disassembly tool for turbine rotor coupling connecting bolts, comprising a frame base, clamping mechanisms fixedly installed on both sides of the frame base, support legs fixedly installed at the four corners of the top of the frame base, a top frame fixedly installed on the top of the support legs, a round seat fixedly installed in the middle of the top of the top frame, a telescopic cylinder fixedly installed in the middle of the top of the round seat, and a disassembly device fixedly installed at the bottom output end of the telescopic cylinder;

[0009] The disassembly device includes a fixed frame, which is fixedly installed at the bottom output end of the telescopic cylinder. A base plate is fixedly installed at the bottom of the fixed frame, a longitudinal adjustment mechanism is fixedly installed in the middle of the base plate, a drive mechanism is fixedly installed at the bottom of the longitudinal adjustment mechanism, an adjustment mechanism is fixedly installed on the outside of the drive mechanism, and a lateral adjustment mechanism is fixedly installed at the bottom of the adjustment mechanism. Disassembly mechanisms are movably installed at the bottom of the lateral adjustment mechanism and the middle of the outside of the drive mechanism. By setting up the disassembly device, the longitudinal adjustment mechanism can be activated during use to assist in longitudinal adjustment. Combined with the design of the lateral adjustment mechanism, the disassembly mechanism can be adjusted both longitudinally and laterally, which can further improve the adaptability of this disassembly tool.

[0010] Furthermore, the longitudinal adjustment mechanism includes a slide groove and a first motor. The first motor is fixedly installed on the middle of one side of the base plate. The slide groove is opened in the middle of the base plate. A bidirectional screw is rotatably connected to the inner side of the slide groove. The two ends of the bidirectional screw have opposite thread directions. Both ends of the bidirectional screw are threadedly connected to sliders. The bottom of the sliders is fixedly connected to the top of the drive mechanism. By setting up the longitudinal adjustment mechanism, the first motor can drive the bidirectional screw to drive the sliders to move, which can assist the adjustment and disassembly mechanism to make longitudinal displacement, making the overall adaptability of this device strong.

[0011] Furthermore, the adjustment mechanism includes side plates, which are fixedly installed at both ends of the outer side of the concave seat. Each side plate has a movable groove at its bottom. A first one-way screw is rotatably connected to the inner side of the movable groove. A drive assembly is fixedly installed on the outer side of the side plate. A movable block is threadedly connected to the outer surface of the first one-way screw. The movable block is slidably connected to the inner side of the cavity of the movable groove. The bottom of the movable block is fixedly connected to the top of the lateral adjustment mechanism. This adjustment mechanism allows the lateral adjustment mechanism to be moved by driving the one-way screw inside the movable groove via the drive assembly during use, facilitating the disconnection of the transmission gear and worm gear and enabling rapid adjustment and adaptation of the equipment.

[0012] Furthermore, the driving mechanism includes a concave seat, which is fixedly installed on the bottom of the slider. A second motor is fixedly installed on one side of the concave seat, and the output end of the second motor passes through the concave seat. A worm gear is rotatably connected to the lower inner side of the concave seat. One end of the worm gear is fixedly connected to the output end of the second motor. The two outer ends of the concave seat are fixedly connected to the adjustment mechanism. By setting the driving mechanism, the second motor can drive the worm gear to rotate during use. The rotation of the worm gear can drive the three sets of disassembly mechanisms to operate in conjunction, thereby assisting in the synchronous and rapid disassembly and assembly of multiple sets of bolts.

[0013] Furthermore, the drive assembly includes a connecting plate, which is fixedly installed between the inner and outer ends of the side plate. A mounting bracket is fixedly installed on the outer side of the connecting plate. Both ends of the mounting bracket near the side plate are rotatably connected to transmission pulleys. A fourth motor is fixedly installed at one outer end of the mounting bracket. The output end of the fourth motor passes through the mounting bracket and is fixedly connected to a transmission pulley. The side of the transmission pulley near the first one-way screw is fixedly connected to the outer end of the first one-way screw. By setting up the drive assembly, during the use of this device, the fourth motor can drive the transmission pulley to rotate the first one-way screw, thereby quickly and synchronously driving the two sets of lateral adjustment mechanisms to move outward, which can improve the adjustment convenience of this device.

[0014] Furthermore, the disassembly mechanism includes a transmission gear, which is rotatably connected to the bottom of the fixed plate and the bottom of the sliding block. The transmission gear meshes with a worm gear, and a mounting base is fixedly installed at the bottom of the transmission gear. A support rod is inserted into the inner side of the mounting base, and a hexagonal threaded sleeve is fixedly installed at the bottom of the support rod. Fixed screws are threaded to the lower ends of both sides of the mounting base. The inner end of the fixed screw passes through the hexagonal threaded sleeve and fits snugly to both sides of the support rod. By setting up the disassembly mechanism, during the use of this equipment, the worm gear can be driven to rotate by starting the second motor, and the transmission gear can be driven to rotate by the worm gear, which in turn drives the hexagonal threaded sleeve to rotate. This allows for quick disassembly and assembly of bolts using the hexagonal threaded sleeve, improving the overall disassembly and assembly efficiency of this equipment. With the support rod and mounting base, the hexagonal threaded sleeve can be flexibly replaced, improving the overall adaptability of this equipment.

[0015] Furthermore, the lateral adjustment mechanism includes a side rail and a fixed plate. The side rail is fixedly installed at the bottom of the movable block, and a third motor is fixedly installed at the outer end of the side rail. The output end of the third motor passes through one end of the side rail. A second one-way screw is rotatably connected to the inner side of the side rail, and a sliding block is threadedly connected to the outer surface of the second one-way screw. The sliding block is slidably connected inside the cavity of the side rail. The fixed plate is fixedly installed at the middle of the outer side of the concave seat. The disassembly mechanism is rotatably connected to the bottom of the sliding block and the fixed plate. By setting up the lateral adjustment mechanism, the second one-way screw can be driven by starting the third motor to drive the sliding block to move laterally. The sliding block can assist in driving the lateral displacement of the disassembly mechanism, which can assist in adjusting and adapting the disassembly device, thus improving the overall adaptability of the equipment.

[0016] Furthermore, the overall cross-sectional shape of the mounting base and the overall cross-sectional shape of the support rod are both set to regular hexagons. An adjustment knob is fixedly installed on the outer end of the fixing screw, and anti-slip textures are evenly spaced on the outer surface of the adjustment knob. The mounting base is set to regular hexagons, which can fit the bolt and facilitate stable disassembly of the bolt. The adjustment knob is set so that the hexagonal threaded sleeve can be disassembled and replaced by turning the adjustment knob.

[0017] Furthermore, the clamping mechanism includes a fixed base, which is fixedly installed on both sides of the frame base. The inner side of the fixed base penetrates the frame base, and an electric push rod is fixedly installed on the inner side of the fixed base. The output end of the electric push rod penetrates the frame base and is fixedly installed with a clamping seat. The inner side of the clamping seat has a clamping groove, and the top view of the clamping groove is set to a V-shape. The clamping mechanism enables the device to quickly clamp and position the coupling by pushing the clamping seat with the electric push rod during use, and can quickly and stably disassemble and assemble the coupling bolts, making it convenient to use.

[0018] Furthermore, the overall cross-sectional shape of the movable block, slider, and sliding block is set to a convex shape, and the cross-sectional shape of the internal cavity of the movable groove, sliding channel, and side rail is also set to a convex shape. Wear-resistant pads are provided on the outer surface of the movable block, slider, and sliding block and on the inner wall of the movable groove, sliding channel, and side rail. The convex shape of the overall cross-sectional shape of the movable block, slider, and sliding block, as well as the shape of the movable groove, sliding channel, and side rail, can improve the stability of the slider's sliding assembly and disassembly. The wear-resistant pads can improve the friction resistance and improve the overall stability of the device.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] Firstly, in this invention, an electric push rod is used to push the clamping seat to clamp the coupling, and then the telescopic cylinder is activated to push the disassembly device downward, causing the hexagonal threaded sleeve to be fitted into the inside of the bolt. At this time, the disassembly device is activated to assist in the synchronous and rapid disassembly of the bolt. The clamping mechanism and the disassembly device adopt a telescopic and adjustable design, which can assist in clamping and positioning couplings of different sizes and improve the stability of the coupling during bolt disassembly.

[0021] Secondly, in this invention, a first motor drives a bidirectional screw to drive a slider, which in turn moves the disassembly mechanism, facilitating the adjustment of the longitudinal spacing of the disassembly mechanism. Then, a fourth motor synchronously drives a first unidirectional screw to move a movable block, separating the transmission gear and the worm gear. Finally, a third motor drives a second unidirectional screw to move a sliding block, which in turn moves the disassembly mechanism laterally, facilitating lateral adjustment of the disassembly mechanism. Combined with the design of the longitudinal adjustment mechanism, this disassembly tool can synchronously adjust the disassembly mechanism for both lateral and longitudinal displacement, enabling flexible adaptation to couplings of different sizes and specifications, further improving the adaptability of this equipment.

[0022] Thirdly, in this invention, during use, the second motor can be started to drive the worm gear to rotate. Since the worm gear and the transmission gear mesh, driving the worm gear to rotate synchronously can drive the transmission gear to rotate synchronously, which can drive the hexagonal threaded sleeve to assist in twisting the bolts. Six sets of bolts can be disassembled simultaneously, which improves the overall disassembly convenience of this equipment. Furthermore, during use, the fixing screw can be disassembled as needed, and the support rod can be pulled out to replace the hexagonal threaded sleeve with the appropriate performance, which further improves the overall adaptability of this equipment.

[0023] Fourth, in this invention, the adjustment design of this equipment can quickly disassemble and assemble multiple sets of bolts simultaneously, completing the disassembly work quickly and efficiently, saving time and labor costs. Furthermore, the synchronous drive of multiple sets of hexagonal screw sleeves for rotational disassembly can avoid equipment damage caused by improper disassembly, extend the service life of the equipment, improve maintenance efficiency, thereby reducing equipment maintenance and repair costs, lowering the operating costs of enterprises, and it can be adjusted according to different coupling sizes and connecting bolt specifications, making it widely applicable.

[0035] The disassembly device 6 includes a fixing frame 61, which is fixedly installed at the bottom output end of the telescopic cylinder 7. A base plate 62 is fixedly installed at the bottom of the fixing frame 61. A longitudinal adjustment mechanism 63 is fixedly installed in the middle of the base plate 62. A drive mechanism 64 is fixedly installed at the bottom of the longitudinal adjustment mechanism 63. An adjustment mechanism 65 is fixedly installed on the outside of the drive mechanism 64. A lateral adjustment mechanism 66 is fixedly installed at the bottom of the adjustment mechanism 65. A disassembly mechanism 67 is movably installed at the bottom of the lateral adjustment mechanism 66 and the middle of the outside of the drive mechanism 64. By setting up the disassembly device 6, the longitudinal adjustment mechanism 63 can be activated during use to assist in longitudinal adjustment. In conjunction with the design of the lateral adjustment mechanism 66, the disassembly mechanism 67 can be adjusted both longitudinally and laterally, which can further improve the adaptability of this disassembly tool.

[0036] Please see Figures 4-7 The longitudinal adjustment mechanism 63 includes a slide groove 631 and a first motor 632. The first motor 632 is fixedly installed on the middle of one side of the base plate 62. The slide groove 631 is opened in the middle of the base plate 62. A bidirectional screw 633 is rotatably connected to the inner side of the slide groove 631. The two ends of the bidirectional screw 633 have opposite threads. Both ends of the bidirectional screw 633 are threadedly connected to sliders 634. The bottom of the sliders 634 is fixedly connected to the top of the drive mechanism 64. During use, the device can be operated by setting the longitudinal adjustment mechanism 63. At this time, the first motor 632 drives the bidirectional screw 633 to rotate, and the bidirectional screw 633 can drive the sliders 634 to move relative to each other. This can assist the adjustment and disassembly mechanism 67 in longitudinal displacement. The spacing of the disassembly mechanism 67 can be adjusted to facilitate flexible disassembly of the device.

[0037] Please see Figures 6-7 The drive mechanism 64 includes a concave seat 641, which is fixedly installed on the bottom of the slider 634. A second motor 642 is fixedly installed on one side of the concave seat 641. The output end of the second motor 642 passes through the concave seat 641. A worm gear 643 is rotatably connected to the lower inner side of the concave seat 641. One end of the worm gear 643 is fixedly connected to the output end of the second motor 642. The two outer ends of the concave seat 641 are fixedly connected to the adjustment mechanism 65. During use, the device can be driven by the second motor 642 to rotate the worm gear 643 through the drive mechanism 64. As the worm gear 643 rotates, the disassembly mechanism 67 can be operated in conjunction with it, which facilitates the simultaneous disassembly of multiple bolts and improves the convenience and efficiency of bolt disassembly.

[0038] Please see Figure 1-5 and Figures 6-8The adjustment mechanism 65 includes side plates 651, which are fixedly installed on both outer ends of the concave seat 641. Each side plate 651 has a movable groove 652 at its bottom. A first one-way screw 653 is rotatably connected to the inner side of the movable groove 652. A drive assembly 655 is fixedly installed on the outer side of the side plate 651. A movable block 654 is threadedly connected to the outer surface of the first one-way screw 653. The movable block 654 is slidably connected to the inner side of the cavity of the movable groove 652. The bottom of the movable block 654 is fixedly connected to the top of the transverse adjustment mechanism 66. During use, the device can be adjusted by using the drive assembly 655 to drive the one-way screw inside the movable groove 652 to rotate. The rotation of the one-way screw drives the transverse adjustment mechanism 66 to move via the movable block 654, facilitating the separation of the transmission gear 671 and the worm gear 643. When the transmission gear 671 and the worm gear 643 are separated, the spacing of the transmission gear 671 can be adjusted, facilitating the use of the device.

[0039] Please see Figures 6-7 The drive assembly 655 includes a connecting plate 6551, which is fixedly installed between the inner and outer ends of the side plate 651. A mounting bracket 6552 is fixedly installed on the outer side of the connecting plate 6551. Both ends of the mounting bracket 6552 near the side plate 651 are rotatably connected to drive pulleys 6553. A fourth motor 6554 is fixedly installed on one outer end of the mounting bracket 6552. The output end of the fourth motor 6554 passes through the mounting bracket 6552 and is fixedly connected to a drive pulley 6553. The drive pulley 6553 is close to the first one-way screw 65. One side of 3 is fixedly connected to the outer end of the first one-way screw 653. During use, the device can be driven by the drive assembly 655, which can drive the transmission pulley 6553 to rotate using the fourth motor 6554. Through the transmission belt, the two sets of transmission pulleys 6553 can be driven to rotate. When the two sets of transmission pulleys 6553 rotate, the two sets of first one-way screws can be driven to rotate synchronously. By rotating the two sets of first one-way screws, the movement of the two sets of lateral adjustment mechanisms 66 can be adjusted, which facilitates quick adjustment of the separation of the gear and worm 643.

[0040] Please see Figure 8The lateral adjustment mechanism 66 includes a side rail 661 and a fixed plate 662. The side rail 661 is fixedly installed at the bottom of the movable block 654. A third motor 663 is fixedly installed at the outer end of the side rail 661. The output end of the third motor 663 passes through one end of the side rail 661. A second one-way screw 664 is rotatably connected to the inner side of the side rail 661. A sliding block 665 is threadedly connected to the outer surface of the second one-way screw 664. The sliding block 665 is slidably connected inside the cavity of the side rail 661. The fixed plate 662 is fixedly installed at the middle of the outer side of the concave seat 641. The disassembly mechanism 67 is rotatably connected to the bottom of the sliding block 665 and the fixed plate 662. During use, the third motor 663 can be started to drive the second one-way screw 664 to drive the sliding block 665 to move laterally. By sliding the sliding block 665 laterally, the disassembly mechanism 67 can be laterally displaced with the assistance of the sliding block 665. This allows for flexible adjustment of the position of the disassembly mechanism 67 during use and enables flexible adaptation to disassembly and adjustment.

[0041] Please see Figures 1-4 and Figures 6-8 The disassembly mechanism 67 includes a transmission gear 671, which is rotatably connected to the bottom of the fixed plate 662 and the bottom of the sliding block 665. The transmission gear 671 meshes with a worm gear 643. A mounting base 672 is fixedly installed on the bottom of the transmission gear 671. A support rod 673 is inserted into the inner side of the mounting base 672. A hexagonal threaded sleeve 674 is fixedly installed on the bottom of the support rod 673. Fixing screws 675 are threaded to the lower ends of both sides of the mounting base 672. The inner ends of the fixing screws 675 pass through the hexagonal threaded sleeves and are fitted together with the two sides of the support rod 673. By setting the disassembly mechanism 67, this equipment can... During use, the second motor 642 drives the worm gear 643 to rotate, which in turn drives the transmission gear 671 to rotate, thus assisting in the rotation of the hexagonal threaded sleeve 674. This allows for quick assembly and disassembly of bolts via the hexagonal threaded sleeve 674, improving the overall assembly and disassembly efficiency of the equipment. Combined with the support rod 673 and mounting base 672, the hexagonal threaded sleeve 674 can be flexibly replaced, enhancing the overall adaptability of the equipment. Furthermore, the hexagonal threaded sleeve 674 is magnetically attached, made of magnetic steel, and can attract bolts after disassembly, facilitating the removal and placement of disassembled bolts.

[0042] Please see Figure 8The overall cross-sectional shape of the mounting base 672 and the support rod 673 are both set as regular hexagons. An adjustment knob is fixedly installed on the outer end of the fixing screw 675, and the outer surface of the adjustment knob is provided with anti-slip texture at equal intervals. The mounting base 672 is set as a regular hexagon so that it can fit the upper end of the bolt, so that the hexagonal threaded sleeve 674 can be stably disassembled and removed from the bolt. The setting of the adjustment knob can improve the friction of the outer end of the fixing screw 675. The adjustment knob can be turned to assist in disassembling and replacing the hexagonal threaded sleeve 674, which is convenient for disassembling and replacing hexagonal threaded sleeves 674 of different sizes. The anti-slip texture can improve the friction of the outer surface of the adjustment knob, which can further improve the ease of adjustment.

[0043] Please see Figures 1-8 The overall cross-sectional shape of the movable block 654, slider 634, and sliding block 665 is set to a convex shape. The cross-sectional shape of the internal cavity of the movable groove 652, sliding groove 631, and side rail 661 is also set to a convex shape. Wear-resistant pads are provided on the outer surface of the movable block 654, slider 634, and sliding block 665 and the inner wall of the movable groove 652, sliding groove 631, and side rail 661. During the use of this equipment, the overall sliding stability of the slider 634, sliding block 665, and sliding block 654 can be improved by adopting the convex shape of the movable block, slider 634, and sliding block 665, as well as the shape of the movable groove 652, sliding groove 631, and side rail 661. This improves the stability of disassembly and assembly of the device during use. The wear-resistant pads can improve the friction resistance of the inner wall of the movable groove 652, sliding groove 631, and side rail 661, further increasing the service life.

[0044] Please see Figures 1-3 The clamping mechanism 2 includes a fixed base 21, which is fixedly installed on both sides of the frame base 1. The inner side of the fixed base 21 penetrates the frame base 1, and an electric push rod 22 is fixedly installed on the inner side of the fixed base 21. The output end of the electric push rod 22 penetrates the frame base 1 and is fixedly installed with a clamping seat 23. A clamping groove 24 is provided on the inner side of the clamping seat 23. The top view shape of the clamping groove 24 is set as V-shaped. The clamping mechanism 2 is set so that during the use of this device, the clamping seat 23 can be pushed by the electric push rod 22 to quickly clamp and position the coupling. The bolts of the coupling can be quickly and stably installed and removed. In addition, the V-shaped clamping groove 24 can be used to clamp and position couplings of different sizes, which can improve the stability of the overall positioning of the coupling.

[0045] The working principle of this invention is as follows: During use, the coupling can be placed in the inner center of the frame 1, and the electric push rod 22 can be activated. The electric push rod 22 drives the clamping seat 23 to move inward. The clamping groove 24 on the inner side of the clamping seat 23 assists in contacting and fixing the two sides of the coupling. Since the clamping groove 24 on the inner side of the clamping seat 23 is V-shaped, it can assist in clamping and positioning the coupling. After the coupling is clamped, the telescopic cylinder 7 can be activated to push the fixing frame 61 to move the base plate 62 downward. The base plate 62 drives the six sets of disassembly mechanisms 67 to be sleeved downward onto the top of the bolt. By activating the disassembly device 6, the bolt can be disassembled synchronously and quickly. The clamping mechanism 2 and the disassembly device 6 are telescopic and adjustable. The design assists in clamping and positioning couplings of different sizes, improving stability during coupling bolt removal. Through the coordinated design of the longitudinal adjustment mechanism 63, the shifting mechanism 65, and the lateral adjustment mechanism 66 of the disassembly device 6, the equipment can be operated by starting the first motor 632, which drives the bidirectional screw 633 to rotate. Since the threads at both ends of the bidirectional screw 633 rotate in opposite directions, the bidirectional screw 633 drives the slider 634 to slide inside the groove 631. The slider 634 assists in moving the disassembly mechanism 67, facilitating adjustment of the longitudinal spacing of the disassembly mechanism 67 and improving the adaptability of the equipment. The fourth motor 6554 is also used. Motor 6554 drives transmission pulley 6553 to rotate. Since the transmission pulleys 6553 are connected by a transmission belt, the fourth motor 6554 can directly drive both sets of transmission pulleys 6553 to rotate. This allows the two sets of transmission pulleys 6553 to synchronously drive the first one-way screw 653 to rotate. The rotation of the first one-way screw 653 drives the movable block 654 to slide inside the movable groove 652. The movement of the movable block 654 separates the transmission gear 671 and the worm gear 643. At this point, the third motor 663 can be activated to drive the second one-way screw 664 to rotate. The rotation of the second one-way screw 664 drives the sliding block 665 to move the disassembly mechanism 67 laterally, facilitating lateral adjustment of the disassembly mechanism 67 in conjunction with longitudinal... The design of the adjustment mechanism 63 allows the disassembly tool to simultaneously adjust the disassembly mechanism 67 for lateral and longitudinal displacement, enabling flexible adaptation to couplings of different sizes and specifications, thus improving the overall adaptability of the equipment. By setting up the disassembly mechanism 67 and the drive mechanism 64 in cooperation, during use, the device can be activated by starting the telescopic cylinder 7 to push the hexagonal threaded sleeve 674 downwards, allowing it to engage with the outer surface of the screw to be disassembled or assembled. Activating the second motor 642 drives the worm gear 643 to rotate. Since the worm gear 643 meshes with the transmission gear 671, the worm gear 643 drives the transmission gear 671 to rotate, which in turn drives the hexagonal threaded sleeve 674 to rotate.The rotation of the worm gear 643 synchronously drives all transmission gears 671 to rotate simultaneously. At this time, the transmission gears 671 drive the hexagonal threaded sleeve 674 to assist in twisting the bolts, allowing the device to simultaneously disassemble six sets of bolts. This improves the overall ease of disassembly. Furthermore, if the bolt size to be disassembled is incompatible with the hexagonal threaded sleeve 674, the fixing screw 675 can be moved outward by turning the adjustment knob. Moving the fixing screw 675 outward allows the support rod 673 to be removed from the hexagonal threaded sleeve 674. Then, simply insert the matching hexagonal threaded sleeve 674 into the mounting base 672. This allows the device to flexibly adapt to the disassembly and assembly of coupling bolts of different sizes, further improving the adaptability of the equipment.
