Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, specifically to a hoisting device for shipbuilding. Background Technology

[0002] Lifting equipment for shipbuilding is an indispensable heavy equipment in the shipbuilding process. It is mainly used for the lifting, transfer and precise assembly of large components such as hull sections, engines and deck components. It is usually composed of a stable support structure, a lifting drive system and load-bearing components. It relies on mechanical power to realize the lifting and displacement of components, which can significantly reduce labor costs and improve work efficiency. It is a core piece of equipment that connects various processes of shipbuilding and ensures the construction progress. It is widely used in shipyard slipways, workshops and other scenarios.

[0003] Most existing shipbuilding hoisting equipment relies on cables to hoist components, lacking auxiliary holding mechanisms. This causes components to sway easily during horizontal movement or lifting, reducing hoisting safety. It may affect the accuracy of component movement or even cause components to collide, thus creating safety hazards. This makes it difficult to meet the high requirements of shipbuilding for hoisting stability and safety. Summary of the Invention

[0004] The purpose of this invention is to provide a hoisting device for shipbuilding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting equipment for shipbuilding, including a gantry frame body, with supporting side columns provided at both ends of the front and rear sides of the gantry frame body, a hoisting module connected to the top of the gantry frame body, a cable provided at the bottom of the hoisting module, and a holding mechanism provided at the inner end of the gantry frame body.

[0006] The holding mechanism includes a horizontal plate, a through slot, a synchronous carriage, a drive inner slot, a lead screw, and a climbing mechanism. A set of horizontal plates is provided at the inner end of the gantry frame body. A through slot is provided in the middle of the horizontal plate, and a set of synchronous carriages is connected through the through slot. A set of drive inner slots is provided at both the front and rear ends of the through slot. A set of lead screws is provided at the inner ends of both sets of drive inner slots. A set of drive motors is provided at the left end of each lead screw. The left and right ends of the horizontal plate are connected to the left and right ends of the gantry frame body through the climbing mechanism.

[0007] By adopting the above technical solution, a horizontal plate is used to provide the installation foundation. The drive motor drives the lead screw to rotate, which in turn drives the synchronous car to move horizontally along the through groove. At the same time, the horizontal plate can be adjusted up and down with the help of the climbing mechanism. This can adapt to the hoisting needs of ship components at different heights and horizontal positions. It adds an auxiliary holding function to the traditional hoisting equipment, which effectively improves the stability of the components during the hoisting process. The structure is reasonable and highly adaptable.

[0008] Preferably, the synchronous vehicle has through slots corresponding to horizontal plates at both the front and rear ends, and each through slot has a drive arm corresponding to a drive inner slot on its inner side. Both sets of drive arms extend into the drive inner slot and are connected to the lead screw. The bottom surface of the synchronous vehicle is provided with no less than two sets of limiting mechanisms.

[0009] By adopting the above technical solution, the synchronous car slides with the horizontal plate through the second through slot, driving the connection between the connecting arm and the lead screw, thereby driving the synchronous car to move horizontally along the horizontal plate. The limiting mechanism set at the bottom of the synchronous car can limit and fix the hoisting components, preventing the hoisting components from shaking when moving horizontally, which is safe and reliable.

[0010] Preferably, all components of the limiting mechanism are identical. The front-end limiting mechanism includes a recycling bottom groove, an upper extension mechanism, a second drive motor, a vertical plate, a lower extension mechanism, a connecting block, and a bonding block. The front end of the synchronous vehicle bottom has at least two sets of recycling bottom grooves. The top of the recycling bottom groove is provided with an upper extension mechanism. The front end of the upper extension mechanism is connected to the second drive motor. The other end of the upper extension mechanism is connected to the lower extension mechanism through the vertical plate. The front end of the lower extension mechanism is connected to a set of bonding blocks through the connecting block.

[0011] By adopting the above technical solution, the limiting mechanism can realize the storage of the upper extension mechanism and the lower extension mechanism by using the recycling bottom groove. It adopts a retractable recycling design, which does not occupy extra space. The drive motor provides power to the upper extension mechanism and the lower extension mechanism is linked by the vertical plate to drive the bonding block to move down and bond to the top of the ship component to fix the ship component. Moreover, the extension structure can be adapted to components of different sizes and shapes, and the limiting stability is strong.

[0012] Preferably, the upper extension mechanism and the lower extension mechanism are mirror images of each other and have the same components. The upper extension mechanism includes a connecting arm one, a connecting arm two, and a gear one. There are two sets of connecting arms one. The left and right ends of the two sets of connecting arms one are connected through connecting arms two, and a set of gear one is provided at the bottom end of the rear end of the connecting arm two.

[0013] By adopting the above technical solution, the connecting arm 1 and connecting arm 2, which are mirror images of each other in the upper and lower extension mechanisms, can form a linkage structure. The gear 1, in conjunction with the power input of the drive motor 2, realizes the extension and retraction of the linkage, thereby realizing the unfolding and retraction of the upper and lower extension mechanisms. The extension stroke is flexible and controllable, and when facing components of different sizes and shapes, it can ensure that the fitting block fully contacts and fixes the components.

[0014] Preferably, the climbing mechanism includes a second gear, a reduction gearbox, a third drive motor, a braking mechanism, a groove, a convex strip, a rack, and a friction groove. A set of second gears is provided at the inner middle of both the left and right ends of the horizontal plate. A set of third drive motors is connected to the rear end of each second gear through a reduction gearbox. A set of braking mechanisms is provided at both the upper and lower ends of each second gear. Grooves corresponding to the second gear and the braking mechanism are provided on both the left and right sides of the gantry frame body. A set of convex strips is provided on the inner side of each groove. A set of racks is provided at the middle of the side of each convex strip near the second gear. A set of friction grooves is provided at the middle of both the front and rear sides of each convex strip.

[0015] By adopting the above technical solution, the climbing mechanism uses the drive motor to drive the gear two through the reduction gearbox to mesh with the rack on the convex strip, so as to realize the synchronous up and down climbing of the horizontal plate and the hoisting component. The braking mechanism can fix the horizontal plate with the convex strip after it reaches the specified height, which improves safety and has high operational stability.

[0016] Preferably, the components of the two sets of braking mechanisms are the same. The braking mechanism at the upper left end includes a movable groove, a linkage frame, a hydraulic push rod, a central shaft, a clamping arm, and a friction disc. The top of the gear two is provided with a set of movable grooves. A set of linkage frames is slidably connected to the right end of the movable grooves. A set of hydraulic push rods is connected to the right end of the linkage frames. A set of central shafts is provided in the middle of the movable grooves. Two sets of clamping arms are connected to the outside of the central shafts. The left ends of the opposite faces of the two sets of clamping arms are provided with friction discs corresponding to the friction grooves.

[0017] By adopting the above technical solution, the braking mechanism drives the linkage frame to slide along the movable groove through the hydraulic push rod. The linkage frame drives the clamping arm to rotate around the central axis, so that the friction disc and the friction grooves on the front and rear sides of the convex strip are closely fitted, thereby achieving braking and positioning of the horizontal plate. The response is rapid, the braking effect is reliable, the safety is high, and it can effectively prevent the horizontal plate from sliding accidentally.

[0018] Preferably, the linkage frame is an inverted "U" shape, and a set of linkage notches corresponding to the clamping arms are provided at both the front and rear ends of the linkage frame, and a set of linkage shafts are provided in each linkage notch.

[0019] By adopting the above technical solution, the inverted "U"-shaped linkage frame can achieve synchronous and uniform power transmission through the linkage notches at both ends and the linkage shaft in cooperation with the clamping arm, ensuring smooth transmission, ensuring that the two sets of clamping arms move synchronously, and improving the braking consistency of the braking mechanism.

[0020] Preferably, each of the clamping arms has a linkage groove corresponding to the linkage shaft at its middle end.

[0021] By adopting the above technical solution, the linkage shaft is located in the linkage groove at the middle end of the clamping arm, which allows the linear motion of the linkage frame to be converted into the rotational motion of the clamping arm. This ensures the matching accuracy and transmission efficiency between the linkage groove and the linkage shaft, avoids jamming during power transmission, and ensures the reliability and timeliness of the braking action.

[0022] Preferably, the rack is embedded in the outer side of the protrusion.

[0023] By adopting the above technical solution, stable meshing with gear two is ensured, and the rack is protected, effectively avoiding the rack from being affected by external factors such as splashes and collisions during hoisting. This not only extends the service life of the rack but also ensures the stability of the climbing mechanism transmission.

[0024] Preferably, the drive shaft of the second drive motor passes through the bottom end of the second front connecting arm and is fixedly connected to the front end of the first bottom connecting arm.

[0025] By adopting the above technical solution, the drive shaft of the second drive motor can directly drive the bottom connecting arm one to rotate, realizing the direct transmission of power. This results in a short power transmission path, low loss, high transmission efficiency, and precise control of the rotation angle of the connecting arm one, ensuring the extension stroke and action accuracy of the upper extension mechanism, thereby ensuring the bonding effect of the bonding block on the component.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention utilizes a retaining mechanism located at the inner end of the gantry frame body. The retaining mechanism includes components such as a horizontal plate, a through slot, a synchronous trolley, a drive inner slot, a lead screw, and a climbing mechanism. These components work together to solve the problem that existing ship lifting equipment lacks auxiliary retaining functions when lifting components, and that components are prone to swaying under the influence of inertial wind force. The retaining mechanism, through the transmission of the drive motor and the lead screw, can drive the synchronous trolley to make horizontal displacement. The climbing mechanism can realize the synchronous up and down adjustment of the horizontal plate and the component. With the limiting mechanism at the bottom of the synchronous trolley, it can adapt to the horizontal and vertical movement path of the component, ensure the stability of the limit, effectively avoid collision damage to the component, and improve the safety and efficiency of lifting.

[0028] 2. This invention utilizes a limiting mechanism located at the bottom of the synchronous vehicle. The limiting mechanism includes components such as a recycling trough, an upper extension mechanism, a second drive motor, a vertical plate, a lower extension mechanism, a connecting block, and a bonding block. The upper and lower extension mechanisms employ a mirror-linked design, coupled with the meshing transmission of a gear and the flexible bonding structure of the bonding block. This allows for stable restriction of components of different sizes and appearances, providing good adaptability. The recycling trough enables storage, reducing space occupation. The connecting block and bonding block, in conjunction with a torsion spring, ensure a tight fit with the components, guaranteeing both the stability of the limiting mechanism and improving the versatility and practicality of the equipment.

[0029] 3. This invention utilizes a climbing mechanism located at both ends of a horizontal plate. The climbing mechanism includes components such as a second gear, a reduction gearbox, a third drive motor, a braking mechanism, grooves, convex bars, racks, and friction grooves. Through the gear and rack climbing structure and the adoption of a double braking mechanism design, the invention solves the problems of easy interference in transmission and insufficient braking reliability of existing climbing devices. The third drive motor drives the second gear through the reduction gearbox to mesh with the rack on the convex bar, achieving precise and synchronous climbing of the horizontal plate. The hydraulic push rod drives the clamping arm to make the friction disc fit with the friction groove. The braking response is rapid and the clamping force is stable, effectively preventing the horizontal plate from sliding unexpectedly and improving the safety of high-altitude hoisting.

Detailed Implementation

[0040] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0041] Please see Figures 1-4 This invention provides a hoisting device for shipbuilding, including a gantry frame body 1. Supporting side columns 2 are installed at both ends of the front and rear sides of the gantry frame body 1 to improve stability. A hoisting module 3 is connected to the top of the gantry frame body 1, and a cable 4 is provided at the bottom of the hoisting module 3. The hoisting module 3 can hoist components via the cable 4. The device also includes a holding mechanism 5 located at the inner end of the gantry frame body 1. The holding mechanism 5 includes a horizontal plate 51, a through groove 52, a synchronous trolley 53, a drive inner groove 54, a lead screw 55, and a climbing mechanism 56. A set of horizontal plates 51 is horizontally arranged at the inner end of the gantry frame body 1. A through slot 52 is provided in the middle of the 51, and a set of synchronous trolleys 53 are connected through the through slot 52. The bottom end of the cable 4 extends through to the bottom end of the synchronous trolley 53 to facilitate the hoisting of components. A set of drive inner slots 54 is provided at both the front and rear ends of the through slot 52. A set of lead screws 55 is provided at the inner end of each set of drive inner slots 54. A set of drive motors 551 is provided at the left end of each lead screw 55. The drive motors 551 can drive the lead screws 55 to rotate. The left and right ends of the horizontal plate 51 are connected to the left and right ends of the gantry frame body 1 through the climbing mechanism 56, which can cooperate with the hoisting module 3 to climb synchronously with the hoisted components.

[0042] Specifically, the horizontal plate 51 provides the installation base, the drive motor 551 drives the lead screw 55 to rotate, and drives the synchronous carriage 53 to move horizontally along the through groove 52. At the same time, the climbing mechanism 56 is used to adjust the horizontal plate 51 up and down, which can adapt to the hoisting needs of ship components at different heights and horizontal positions. It adds an auxiliary holding function to the traditional hoisting equipment, effectively improving the stability of the components during hoisting. The structure is reasonable and highly adaptable.

[0043] Please see Figure 3 The synchronous carriage 53 has through slots 531 at both the front and rear ends corresponding to the horizontal plate 51. The inner side of each through slot 531 has a drive arm 532 corresponding to the drive inner slot 54. Both sets of drive arms 532 extend into the drive inner slot 54 and connect to the lead screw 55. The drive arm 532 has an internal threaded hole at the position corresponding to the lead screw 55. When the lead screw 55 rotates, it can drive the drive arm 532 and the synchronous carriage 53 to move horizontally along the through slot 52 through the internal threaded hole. The bottom surface of the synchronous carriage 53 has no less than two sets of limiting mechanisms 533.

[0044] Specifically, the synchronous trolley 53 slides with the horizontal plate 51 through the through slot 2 531, driving the connection between the connecting arm 532 and the lead screw 55, thereby driving the synchronous trolley 53 to move horizontally along the horizontal plate 51. The limiting mechanism 533 set at the bottom of the synchronous trolley 53 can limit and fix the hoisting components to prevent the hoisting components from shaking when moving horizontally, which is safe and reliable.

[0045] Please see Figure 5 All components of the limiting mechanism 533 are identical. The front limiting mechanism 533 includes a recycling bottom trough 5331, an upper extension mechanism 5332, a second drive motor 5333, a vertical plate 5334, a lower extension mechanism 5335, a connecting block 5336, and a bonding block 5337. The front end of the synchronous car 53 has at least two sets of recycling bottom troughs 5331. The upper extension mechanism 5332 is provided at the top of the recycling bottom trough 5331. The front end of the upper extension mechanism 5332 is connected to the second drive motor 5333, and the other end of the upper extension mechanism 5332 is connected to the vertical plate 5334. 34 is connected to a lower extension mechanism 5335. The second drive motor 5333 can output power to drive the upper extension mechanism 5332 and the lower extension mechanism 5335 to extend closer to the top of the hoisting component and limit and fix the hoisting component. The front end of the lower extension mechanism 5335 is connected to a set of fitting blocks 5337 through a connecting block 5336. The fitting blocks 5337 can fit against the top of the hoisting component. The connecting block 5336 and the fitting blocks 5337 are hinged, and a torsion spring is provided at the connection point. The torsion spring can ensure the connection posture of the fitting blocks 5337 and the connecting block 5336.

[0046] Specifically, the limiting mechanism 533 utilizes the recycling bottom groove 5331 to store the upper extension mechanism 5332 and the lower extension mechanism 5335. It adopts a retractable and recyclable design, which does not occupy extra space. The drive motor 5333 provides power to the upper extension mechanism 5332, and the vertical plate 5334 links the lower extension mechanism 5335 to drive the bonding block 5337 to move down and bond to the top of the ship component to fix the ship component. Moreover, the extension structure can adapt to components of different sizes and shapes, and the limiting stability is strong.

[0047] Please see Figure 5 The upper extension mechanism 5332 and the lower extension mechanism 5335 are mirror images of each other and have identical components. The upper extension mechanism 5332 includes a first connecting arm 53321, a second connecting arm 53322, and a first gear 53323. There are two sets of first connecting arms 53321, and both ends of the two sets of first connecting arms 53321 are connected through second connecting arms 53322. The front end of the second connecting arm 53322 is fixedly connected to the recovery trough 5331. The drive shaft of the second drive motor 5333 passes through the bottom end of the front end of the second connecting arm 53322 and is fixedly connected to the front end of the bottom end of the first connecting arm 53321. The drive shaft of the second drive motor 5333 can directly drive the bottom end of the first connecting arm 53321 to rotate, realizing direct power transmission. This results in a short power transmission path, low loss, high transmission efficiency, and precise control of the rotation angle of the first connecting arm 53321, ensuring the smooth operation of the upper extension mechanism 5335. The extension stroke and motion accuracy of 32 ensure the fitting effect of the fitting block 5337 on the component. The two sets of connecting arms 53321 remain parallel during the rotation and extension process, and the bottom end of the rear connecting arm 53322 is provided with a set of gears 53323. The gears 53323 in the upper extension mechanism 5332 and the lower extension mechanism 5335 mesh with each other. When the upper extension mechanism 5332 is driven to rotate by the drive motor 5333, the gears 53323 can drive the lower extension mechanism 5335 to unfold synchronously. Furthermore, the connecting arm 53322 at the rear end of the upper extension mechanism 5332 and the lower extension mechanism 5335 can be fixed by the vertical plate 5334, so that the two sets of gears 53323 are fixed at a fixed distance and always meshed, avoiding gaps caused by the extension movement of the upper extension mechanism 5332 and the lower extension mechanism 5335, which would affect the power transmission.

[0048] Specifically, the connecting arm 53321 and connecting arm 53322, which are mirror images of each other in the upper extension mechanism 5332 and the lower extension mechanism 5335, can form a linkage structure. The gear 53323, in conjunction with the power input of the drive motor 5333, realizes the extension and retraction of the linkage, thereby realizing the unfolding and retraction of the upper extension mechanism 5332 and the lower extension mechanism 5335. The extension stroke is flexible and controllable, and when facing components of different sizes and shapes, it can ensure that the fitting block 5337 fully contacts and fixes the components.

[0049] Please see Figure 1 and Figure 6 The climbing mechanism 56 includes a second gear 561, a reduction gearbox 562, a third drive motor 563, a braking mechanism 564, a groove 565, a ridge 566, a rack 567, and a friction groove 568. A set of second gears 561 is provided at the inner center of both the left and right ends of the horizontal plate 51. The rear end of each second gear 561 is connected to a third drive motor 563 via the reduction gearbox 562. The third drive motor 563 can drive the second gear 561 to rotate through the reduction gearbox 562. A braking mechanism 564 is provided at both the upper and lower ends of the second gear 561. Corresponding second gears 561 and braking mechanisms are provided on both the left and right sides of the gantry frame body 1. The groove 565 of 564 has a set of protruding strips 566 on its inner side. The groove 565 and the protruding strips 566 are integrated to ensure connection strength. A set of racks 567 are embedded in the middle of the side of the protruding strips 566 near the gear 2 561. This ensures stable meshing with the gear 2 561 and also protects the racks 567, effectively preventing them from being affected by external factors such as flying objects and collisions during hoisting. This not only extends the service life of the racks 567 but also ensures the stability of the climbing mechanism 56 transmission. A set of friction grooves 568 are opened in the middle of both the front and rear sides of the protruding strips 566.

[0050] Specifically, the climbing mechanism 56 uses a drive motor 563 to drive a gear 561 via a reduction gearbox 562 to mesh with a rack 567 on a convex rib 566, thereby achieving synchronous up-and-down climbing of the horizontal plate 51 and the hoisting component. The braking mechanism 564 can fix the horizontal plate 51 to the convex rib 566 after it reaches a specified height, improving safety and ensuring high operational stability.

[0051] Please see Figures 7-9 The two sets of braking mechanisms 564 have identical components. The upper left braking mechanism 564 includes a movable groove 5641, a linkage frame 5642, a hydraulic push rod 5643, a central shaft 5644, a clamping arm 5645, and a friction disc 5646. A movable groove 5641 is provided at the top of the gear 561. A linkage frame 5642 is slidably connected to the right end of the movable groove 5641. A hydraulic push rod 5643 is connected to the right end of the linkage frame 5642. The hydraulic push rod 5643 can move the linkage frame 5642 left and right by pushing or retracting its output end. A central shaft 5644 is fixedly connected to the middle of 641. Two sets of clamping arms 5645 are rotatably connected to the outside of the central shaft 5644. The other ends of the two sets of clamping arms 5645 extend through to the front and rear ends of the groove 565, respectively. The opposing surfaces of the two sets of clamping arms 5645 are fixedly connected to friction discs 5646 corresponding to friction grooves 568. When the two sets of clamping arms 5645 rotate relative to each other around the central shaft 5644, the friction discs 5646 can be pressed into the friction grooves 568 to rub and fix the inner side of the friction grooves 568, thereby preventing the horizontal plate 51 from slipping and tilting.

[0052] Specifically, the braking mechanism 564 drives the linkage frame 5642 to slide along the movable groove 5641 via the hydraulic push rod 5643. The linkage frame 5642 drives the clamping arm 5645 to rotate around the central axis 5644, so that the friction disc 5646 and the friction grooves 568 on the front and rear sides of the convex strip 566 are tightly fitted, thereby achieving braking and positioning of the horizontal plate 51. The response is rapid, the braking effect is reliable, the safety is high, and it can effectively prevent the horizontal plate 51 from sliding accidentally.

[0053] Please see Figure 9 The linkage frame 5642 is an inverted "U" shape. Both the front and rear ends of the linkage frame 5642 are provided with a set of linkage notches 56421 corresponding to the clamping arms 5645. A set of linkage shafts 56422 is provided in each linkage notch 56421. The middle end of each clamping arm 5645 is provided with a linkage groove 56451 corresponding to the linkage shaft 56422. The linkage shaft 56422 is located in the linkage groove 56451.

[0054] Specifically, the inverted "U"-shaped linkage frame 5642, through the linkage notches 56421 at both ends and the linkage shaft 56422, cooperates with the clamping arm 5645 to achieve synchronous and uniform power transmission, ensuring smooth transmission and ensuring that the two sets of clamping arms 5645 move synchronously, thus improving the braking consistency of the braking mechanism 564. The linkage shaft 56422 is located in the linkage groove 56451 at the middle of the clamping arm 5645, so that the linear motion of the linkage frame 5642 can be converted into the rotational motion of the clamping arm 5645. This ensures the matching accuracy and transmission efficiency of the linkage groove 56451 and the linkage shaft 56422, avoids jamming during power transmission, and ensures the reliability and timeliness of the braking action.

[0055] This invention provides a hoisting device for shipbuilding. Through a holding mechanism 5 located inside the gantry frame body 1, the holding mechanism 5 includes components such as a horizontal plate 51, a through slot 52, a synchronous trolley 53, a drive inner slot 54, a lead screw 55, and a climbing mechanism 56. These components work together to solve the problem of existing ship hoisting equipment lacking auxiliary holding functions when hoisting components, leading to component swaying under the influence of inertial wind forces. The holding mechanism 5, through the transmission of a drive motor 551 and the lead screw 55, can drive the synchronous trolley 53 to perform horizontal displacement, while the climbing mechanism 56 can synchronously adjust the horizontal plate 51 and the component up and down. The limiting mechanism 533 at the bottom of the synchronous trolley 53 can adapt to the horizontal and vertical movement paths of the components, ensuring limiting stability, effectively avoiding collision damage to the components, and improving hoisting safety and efficiency. The limiting mechanism 533, located at the bottom of the synchronous trolley 53, includes components such as a recovery trough 5331, an upper extension mechanism 5332, a second drive motor 5333, a vertical plate 5334, a lower extension mechanism 5335, a connecting block 5336, and an abutment block 5337. The upper extension mechanism 5332 and the lower extension mechanism 5335 adopt a mirror linkage design, coupled with gears... The meshing transmission of wheel 53323 and the flexible bonding structure of bonding block 5337 can stably restrict components of different sizes and appearances, with good adaptability. The recycling trough 5331 facilitates storage, reducing space occupation. The connecting block 5336 and bonding block 5337, in conjunction with a torsion spring, ensure a tight fit with the components, guaranteeing both secure positioning and improved equipment versatility and practicality. The climbing mechanism 56, located at both ends of the horizontal plate 51, includes gear 561, a reduction gearbox 562, a drive motor 563, a brake mechanism 564, a groove 565, and a protrusion 56. 6. The rack 567 and friction groove 568, etc., through the rack and pinion climbing structure and the design of the double braking mechanism 564, solve the problems of easy interference in the transmission and insufficient braking reliability of the existing climbing device. The drive motor 563 drives the gear 561 through the reduction gearbox 562 to mesh with the rack 567 on the convex strip 566, so as to achieve precise synchronous climbing of the horizontal plate 51. The hydraulic push rod 5643 drives the clamping arm 5645 to drive the friction disc 5646 to fit with the friction groove 568. The braking response is fast and the clamping force is stable, which effectively prevents the horizontal plate 51 from sliding accidentally and improves the safety of high-altitude hoisting.
