Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine lifting equipment, in particular to a wind turbine equipped with a lifting equipment. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator (including the device), a direction regulator (tail wing), a tower, a speed limit safety component and an energy storage device.

[0003] Due to the high height of wind turbines, workers need to take a non-climbing device to ascend and descend when inspecting and repairing the wind turbines. However, when the non-climbing device encounters power outages, failures or other emergencies, workers are required to manually take deceleration measures. If the operator cannot react quickly and take accurate countermeasures, people may fall and get injured. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a wind turbine generator with a lifting device, including a generator body, a shell is arranged on the front of the generator body, a fixing plate 1 is fixedly connected to the right side of the shell, a protective shell is fixedly connected to the bottom of the shell, a limiting ring is fixedly connected to the side of the right side of the shell close to the fixing plate 1, a guide rail is arranged on the back of the fixing plate 1, a rotating wheel is contacted on the front of the guide rail, the left side of the rotating wheel is rotatably connected to the right side of the shell, and a sliding groove is arranged at the bottom of the shell;

[0005] The anti-falling component includes a moving block, the outer surface of the moving block contacts the inner wall of the sliding groove, a hydraulic cylinder 1 is fixedly connected to the top of the moving block, the front of the hydraulic cylinder 1 is fixedly connected to the back of the shell, the right side of the hydraulic cylinder 1 is fixedly connected to the hydraulic cylinder 2, the right side of the hydraulic cylinder 2 is fixedly connected to the connecting plate, the number of the hydraulic cylinder 2 is two, and the two hydraulic cylinders 2 are symmetrically arranged with the hydraulic cylinder 1 as the center. After entering the equipment, the staff of the present invention can step on the moving block with both feet to make the moving block drive the hydraulic cylinder 1 to move downward, and the movement of the hydraulic cylinder 1 will cause the liquid in the two hydraulic cylinders 2 to be drawn into the hydraulic The reduction of liquid in cylinder 1 and cylinder 2 will cause the two connecting plates to shrink inward, closing the two sliding doors. When ascending, the staff only needs to stand on the moving block to avoid accidentally opening the sliding door and falling. At the same time, after leaving the moving block, the hydraulic cylinder 1 will move upward under the action of the spring, so that the liquid inside it enters the hydraulic cylinder 2. At this time, the two connecting plates will drive the two sliding doors to move in opposite directions. This component can not only automatically open and close, but also prevent the hidden danger of falling of the staff when ascending, thereby improving the overall safety of the device.

[0006] There are two speed reducers, and the parts contained in the two speed reducers are the same. The speed reducer includes a rotating column, the left side of the rotating column is rotatably connected to the right side of the outer shell, a spring hook is fixedly connected to the outer surface of the rotating column, a rotating block is fixedly connected to the right side of the spring hook, and the inner wall of the limiting ring contacts with a pulling rod.

[0007] Preferably, a sliding door is fixedly connected to the left side of the connecting plate, the bottom of the sliding door is in contact with the inner wall of the outer shell, a spring is fixedly connected to the bottom of the moving block, the bottom of the spring is fixedly connected to the bottom of the inner wall of the outer shell, the number of connecting plates is two, and the two connecting plates are symmetrically arranged with the moving block as the center, and the number of sliding doors is two, and the two sliding doors are symmetrically arranged.

[0008] Preferably, a second fixed plate is fixedly connected to the back of the sliding door, a fixed deceleration block is rotatably connected to the outer surface of the pulling rod, and a rotating rod is rotatably connected to the side of the fixed deceleration block away from the pulling rod.

[0009] Preferably, the left side of the rotating rod is rotatably connected to the right side of the shell through a pin shaft, the outer surface of the pulling rod is rotatably connected to a rotating deceleration block on one side close to the fixed deceleration block, and the rotating wheel is fixedly connected to a rotating ring on one side close to the shell. During the rising process of the device of the present invention, if the traction rope is disconnected or a rapid fall occurs, the rotating block 1 contacts the guide rail, which will drive the rotating column and the spring hook 1 to rotate during the falling process. Due to the influence of gravity, the rotation speed of the rotating block 1 will increase. At the same time, the spring hook 1 will extend outward due to the influence of centrifugal force. The extended spring hook 1 will be hung in the groove opened in the pulling rod during the rotation process. Since the moving range of the pulling rod is limited, the rotating block 1 will stagnate. It rotates and generates friction with the guide rail, and slows down the descent speed. Since the rotating deceleration block can rotate, the pulling rod will pull it while moving to make it contact with the bottom of the rotating ring. Since the rotating rod is restricted from above and cannot rotate upward, the fixed deceleration block will extend its longest end to the top of the rotating ring under the pull of the pulling rod, so that the rotating ring is restricted and stopped, and the friction between the rotating wheel and the guide rail is increased, which decelerates the device for the second time. At the same time, the device is stopped under the action of the stagnation component. Compared with some free climbers, this device can use the centrifugal force during the fall to automatically decelerate the device when the staff cannot react in time, so as to avoid serious injuries to the staff due to untimely reaction and inability to operate in an emergency.

[0010] Preferably, a locking protection assembly is provided on the right side of the shell, and the number of the locking protection assemblies is two. The parts contained in the two locking protection assemblies are the same. The locking protection assembly includes a rotating block 2, the outer surface of the rotating block 2 is in contact with the inner wall of the rotating block 1, and a limiting groove is provided on the left side of the rotating block 2. The inner wall of the limiting groove is in contact with a fixed column, and the left side of the fixed column is fixedly connected to the right side of the rotating block 1.

[0011] Preferably, a spring hook 2 is fixedly connected to the right side of the rotating block 2, a rotating hole is provided at the center of the left side of the rotating block 2, a spring limit plate is rotatably connected to the inner wall of the rotating hole, the bottom of the spring limit plate contacts a thorn gear, the left side of the thorn gear is fixedly connected to the right side of the rotating block 1, a fixed groove is provided on the left side of the fixed plate 1, and a fixed tooth is fixedly connected to the inner wall of the fixed groove. The number of fixed teeth is several, and the several fixed teeth are arranged in a ring array. When the rotating block 1 rotates, the rotating block 2 is driven to rotate through the fixed column. Since the spring hook 2 is shorter than the spring hook 1, it will not be hung and stopped first. The rotating block 1 is restricted when it is hung on the pulling rod and will suddenly stop rotating. The rotating block 2 will continue to rotate under the influence of inertia under the action of the limit groove. The spring gear is fixed on the rotating block one, so that the thorn gear is stopped at the same time when the rotating block one stops. At this time, the rotating block two which continues to rotate due to inertia will drive the spring limit plate to move while contacting with the thorn gear, and the limit groove and the spring limit plate can limit the movable range of the rotating block two, so as to strengthen the reduction device as a whole, and avoid the spring hook one from suddenly stopping and shaking and reverse displacement when hanging on the pulling rod, which causes the rotating block one to be unhooked. The component can use inertia to lock the reduction device, and can also bear part of the force exerted on the spring hook one, so as to protect the spring hook together, and at the same time, it can also play a limiting role to prevent the reduction failure caused by the unhooking of the rotating block one.

[0012] Preferably, a stagnation assembly is arranged above the shell, and the number of the stagnation assemblies is two. The parts contained in the two stagnation assemblies are the same. The stagnation assembly includes a telescopic cylinder 1, the bottom of the telescopic cylinder 1 is fixedly connected to the top of the fixed plate 2, and the top of the telescopic cylinder 1 is fixedly connected to the conveying pipe.

[0013] Preferably, a diverter cylinder is fixedly connected to a side of the delivery tube away from the telescopic cylinder one, a telescopic cylinder two is fixedly connected to the right side of the diverter cylinder, a friction plate is fixedly connected to the front side of the telescopic cylinder two, and there are two telescopic cylinders two, which are symmetrically arranged with the guide rail as the center. The present invention can drive the telescopic cylinder one to push upward by pulling the rod upward, so that the liquid inside it is pushed into the delivery tube. Since the delivery tube contains liquid, the excess liquid will be delivered to the diverter cylinder. The diverter cylinder is connected to the two telescopic cylinders two, and the movement of the liquid will push the two friction plates in opposite directions at the same time, causing friction between them and the guide rail. Since the device has been decelerated before, the friction force generated by the two friction plates on the guide rail will cause it to decelerate again and then stagnate, so that the device will decelerate again after deceleration until the device stops falling, avoiding the problem that the decelerated device falls to the ground and may cause injuries to the staff. It not only ensures the safety of the staff, but also effectively protects the equipment.

[0014] The present invention has the following beneficial effects:

[0015] (1) During the ascent of the device of the present invention, if the traction rope is disconnected or the device falls rapidly, the rotating block 1 contacts the guide rail, which will drive the rotating column and the spring hook 1 to rotate during the falling process. Due to the influence of gravity, the rotation speed of the rotating block 1 will increase. At the same time, the spring hook 1 will extend outward due to the centrifugal force. The extended spring hook 1 will be hung in the groove of the pull rod during the rotation process. Since the moving range of the pull rod is limited, the rotating block 1 will stop rotating and produce friction with the guide rail, thereby slowing down the descent speed. Since the rotation speed reduction block can rotate The pulling rod will pull it while moving so that it contacts the bottom of the rotating ring. Since the rotating rod is restricted from above and cannot rotate upward, the fixed deceleration block will extend its longest end to the top of the rotating ring under the pull of the pulling rod, so that the rotating ring is restricted and stopped, and the friction between the rotating wheel and the guide rail is increased, which decelerates the device for a second time. At the same time, the device is stopped under the action of the stagnation component. Compared with some free-climbing devices, this device can use the centrifugal force during the fall to automatically decelerate the device when the staff cannot react in time, thereby avoiding serious injuries to the staff due to untimely reaction and inability to operate in an emergency.

[0016] (2) The present invention drives the rotating block 2 to rotate through the fixed column while the rotating block 1 rotates. Since the spring hook 2 is shorter than the spring hook 1, it will not be hung and stopped first. The rotating block 1 is restricted when it is hung on the pulling rod and will suddenly stop rotating. The rotating block 2 will continue to rotate under the influence of inertia under the action of the limit groove, so that the spring hook 2 is hung on the fixed tooth. Since the thorn gear is fixed on the rotating block 1, the thorn gear will stop rotating at the same time when the rotating block 1 stops rotating. At this time, the rotating block 2 that continues to rotate under inertia will bring The movable spring limit plate moves while contacting the thorn gear, and the limit groove and the spring limit plate can limit the movable range of the rotating block 2, so as to reinforce the reduction device as a whole, and prevent the spring hook 1 from suddenly stopping and shaking and displacing in the reverse direction when hanging on the pull rod, causing the rotating block 1 to be unhooked. The component can use inertia to lock the reduction device, and can also bear part of the force exerted on the spring hook 1, thereby protecting the spring hook together, and at the same time, it can also limit the reduction assembly, and prevent the reduction failure caused by the unhooking of the rotating block 1.

[0017] (3) The present invention can drive the telescopic cylinder 1 upward by pulling the rod upward, so that the liquid inside it is pushed into the delivery pipe. Since the delivery pipe contains liquid, the excess liquid will be delivered to the diversion cylinder. The diversion cylinder is connected to the two telescopic cylinders 2. The movement of the liquid will push the two friction plates in opposite directions at the same time, causing friction between them and the guide rail. Since the device has been decelerated before, the friction force generated by the two friction plates on the guide rail will cause it to decelerate again and then stagnate, causing the device to decelerate again after deceleration until the device stops falling, thereby avoiding the problem that the decelerated device falls to the ground and may cause injuries to the staff. This not only ensures the safety of the staff, but also effectively protects the equipment.

[0018] (4) After the staff enters the equipment of the present invention, they can step on the moving block with both feet to make the moving block drive the hydraulic cylinder one to move downward. The movement of the hydraulic cylinder one will cause the liquid in the two hydraulic cylinders two to be drawn into the hydraulic cylinder one. The reduction of the liquid in the hydraulic cylinder two will cause the two connecting plates to shrink inward, so that the two sliding doors are closed. When ascending, the staff only needs to continue to stand on the moving block to avoid accidentally opening the sliding door and falling. At the same time, after leaving the moving block, the hydraulic cylinder one will move upward under the action of the spring, so that the liquid inside it enters the hydraulic cylinder two. At this time, the two connecting plates will drive the two sliding doors to move in opposite directions. This component can not only perform automatic opening and closing, but also prevent the hidden danger of workers falling when ascending, thereby improving the overall safety of the device.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1-Figure 4 The present invention is a wind turbine with a lifting device, comprising a generator body 1, a shell 11 is arranged on the front of the generator body 1, a fixing plate 111 is fixedly connected to the right side of the shell 11, a protective shell 112 is fixedly connected to the bottom of the shell 11, a limiting ring 12 is fixedly connected to the right side of the shell 11 close to the fixing plate 111, a guide rail 13 is arranged on the back of the fixing plate 111, a rotating wheel 14 is contacted on the front of the guide rail 13, the left side of the rotating wheel 14 is rotatably connected to the right side of the shell 11, and a sliding groove is provided at the bottom of the shell 11;

[0033] The anti-falling component 2 includes a moving block 21, the outer surface of the moving block 21 contacts the inner wall of the sliding groove, the top of the moving block 21 is fixedly connected with a hydraulic cylinder 1 211, the front of the hydraulic cylinder 1 211 is fixedly connected to the back of the shell 11, the right side of the hydraulic cylinder 1 211 is fixedly connected with a hydraulic cylinder 2 212, the right side of the hydraulic cylinder 2 212 is fixedly connected with a connecting plate 22, the number of the hydraulic cylinder 2 212 is two, and the two hydraulic cylinders 212 are symmetrically arranged with the hydraulic cylinder 1 211 as the center. After the staff enters the equipment, the present invention can step on the moving block 21 with both feet to make the moving block 21 drive the hydraulic cylinder 1 211 to move downward, and the movement of the hydraulic cylinder 1 211 will make the two hydraulic cylinders 21 2 is drawn into hydraulic cylinder 1 211, and the reduction of liquid in hydraulic cylinder 212 will cause the two connecting plates 22 to shrink inward, so that the two sliding doors 23 are closed. When the staff is ascending, they only need to continue to stand on the moving block 21 to avoid accidentally opening the sliding door 23 and falling. At the same time, after leaving the moving block 21, the hydraulic cylinder 1 211 will move upward under the action of the spring 24, so that the liquid inside it enters the hydraulic cylinder 212. At this time, the two connecting plates 22 will drive the two sliding doors 23 to move in opposite directions. This component can not only perform automatic opening and closing, but also prevent the hidden danger of falling of the staff when ascending, thereby improving the overall safety of the device.

[0034] The reduction gear 3 is two in number, and the parts contained in the two reduction gears 3 are the same. The reduction gear 3 includes a rotating column 31, and the left side of the rotating column 31 is rotatably connected to the right side of the outer shell 11. A spring hook 311 is fixedly connected to the outer surface of the rotating column 31, and a rotating block 312 is fixedly connected to the right side of the spring hook 311. The inner wall of the limiting ring 12 contacts with a pulling rod 32.

[0035] A sliding door 23 is fixedly connected to the left side of the connecting plate 22, and the bottom of the sliding door 23 contacts the inner wall of the outer shell 11. A spring 24 is fixedly connected to the bottom of the moving block 21, and the bottom of the spring 24 is fixedly connected to the bottom of the inner wall of the outer shell 11. There are two connecting plates 22, and the two connecting plates 22 are symmetrically arranged with the moving block 21 as the center. There are two sliding doors 23, and the two sliding doors 23 are symmetrically arranged.

[0036] For example 2, please refer to Figure 5-Figure 9 The present invention is a wind turbine with a lifting device. Based on the first embodiment, preferably, a second fixing plate 321 is fixedly connected to the back of the sliding door 23, a fixed deceleration block 331 is rotatably connected to the outer surface of the pulling rod 32, and a rotating rod 33 is rotatably connected to the side of the fixed deceleration block 331 away from the pulling rod 32.

[0037] The left side of the rotating rod 33 is rotatably connected to the right side of the shell 11 through a pin shaft, and the outer surface of the pulling rod 32 is rotatably connected to a rotating deceleration block 34 on one side close to the fixed deceleration block 331, and the rotating wheel 14 is fixedly connected to a rotating ring 35 on one side close to the shell 11. During the rising process of the device of the present invention, if the traction rope is disconnected or a rapid fall occurs, the rotating block 1312 contacts the guide rail 13, which will drive the rotating column 31 and the spring hook 131 to rotate during the falling process. Due to the influence of gravity, the rotation speed of the rotating block 1312 will increase. At the same time, the spring hook 1311 will extend outward due to the influence of centrifugal force. The extended spring hook 1311 will be hung in the notch provided in the pulling rod 32 during the rotation process. Since the moving range of the pulling rod 32 is limited, the rotating Block 1 312 will stop rotating and generate friction with the guide rail 13, and slow down the descent speed. Since the rotating deceleration block 34 is rotatable, the pulling rod 32 will pull it while moving so that it contacts the bottom of the rotating ring 35. Since the rotating rod 33 is restricted from rotating upward by the upper limit, the fixed deceleration block 331 will extend its longest end to the top of the rotating ring 35 under the pulling of the pulling rod 32, so that the rotating ring 35 is restricted and stopped, and the friction between the rotating wheel 14 and the guide rail 13 is increased, so that the device is decelerated for a second time, and the device is stopped under the action of the stagnation component 5. Compared with some free-climbing devices, this device can use the centrifugal force during falling to automatically decelerate the device when the staff cannot react in time, so as to avoid serious injuries to the staff due to untimely reaction and inability to operate in an emergency.

[0038] A locking protection component 4 is arranged on the right side of the housing 11. There are two locking protection components 4. The two locking protection components 4 comprise the same parts. The locking protection component 4 includes a rotating block 2 41. The outer surface of the rotating block 2 41 contacts the inner wall of the rotating block 1 312. A limiting groove 411 is arranged on the left side of the rotating block 2 41. The inner wall of the limiting groove 411 contacts a fixing column 43. The left side of the fixing column 43 is fixedly connected to the right side of the rotating block 1 312.

[0039] A spring hook 2 44 is fixedly connected to the right side of the rotating block 2 41, a rotating hole is opened at the center of the left side of the rotating block 2 41, and a spring limiting plate 421 is rotatably connected to the inner wall of the rotating hole, and the bottom of the spring limiting plate 421 contacts the thorn gear 42, and the left side of the thorn gear 42 is fixedly connected to the right side of the rotating block 1 312, and a fixing groove is opened on the left side of the fixing plate 111, and a fixing tooth 45 is fixedly connected to the inner wall of the fixing groove. The number of the fixing teeth 45 is several, and the several fixing teeth 45 are arranged in a ring array. When the rotating block 1 312 rotates, the rotating block 2 41 is driven to rotate through the fixing column 43. Since the spring hook 2 44 is shorter than the spring hook 1 311, it will not be hung and stopped first. The rotating block 1 312 is restricted when it is hung on the pulling rod 32, and it will suddenly stop rotating. The rotating block 2 41 will continue to rotate under the influence of inertia under the action of the limiting groove 411, so that The spring hook 2 44 is hung on the fixed tooth 45. Since the thorn gear 42 is fixed on the rotating block 1 312, the thorn gear 42 will also stop when the rotating block 1 312 stops. At this time, the rotating block 2 41 which continues to rotate due to inertia will drive the spring limit plate 421 to move while contacting with the thorn gear 42, and the limit groove 411 and the spring limit plate 421 can limit the movable range of the rotating block 2 41, so that the reduction gear 3 can be reinforced as a whole to prevent the spring hook 1 311 from suddenly stopping and shaking and reverse displacement when hanging on the pulling rod 32, causing the rotating block 1 312 to be unhooked. The component can use inertia to lock the reduction gear 3, and can also bear part of the force exerted on the spring hook 1 311, thereby protecting the spring hook 1 311, and also limiting the reduction assembly 3 to prevent the reduction failure caused by the unhooking of the rotating block 1 312.

[0040] A stagnation component 5 is arranged above the shell 11. There are two stagnation components 5. The two stagnation components 5 contain the same parts. The stagnation component 5 includes a telescopic cylinder 51. The bottom of the telescopic cylinder 51 is fixedly connected to the top of the fixed plate 321. The top of the telescopic cylinder 51 is fixedly connected to a conveying pipe 511.

[0041] A diverter tube 52 is fixedly connected to the side of the delivery tube 511 away from the telescopic tube 1 51, and a telescopic tube 2 521 is fixedly connected to the right side of the diverter tube 52. A friction plate 522 is fixedly connected to the front of the telescopic tube 2 521. There are two telescopic tubes 2 521, and the two telescopic tubes 2 521 are symmetrically arranged with the guide rail 13 as the center. The present invention can drive the telescopic tube 1 51 to move upward by pulling the rod 32 upward, so that the liquid inside it is pushed into the delivery tube 511. Since the delivery tube 511 contains liquid, the excess liquid will be delivered to the diverter tube 52. The diversion cylinder 52 is connected to two telescopic cylinders 521. The movement of the liquid will push the two friction plates 522 in opposite directions at the same time, causing them to rub against the guide rail 13. Since the device has been decelerated before, the friction force generated by the two friction plates 522 on the guide rail 13 will cause it to decelerate again and then stagnate, causing the device to decelerate again after deceleration until the device stops falling, avoiding the problem that the decelerated device falls to the ground and may cause injuries to the staff. This not only ensures the safety of the staff, but also effectively protects the equipment.

[0042] A specific application of this embodiment is: after the staff enters the equipment, they can step on the moving block 21 with both feet, so that the moving block 21 drives the hydraulic cylinder 1 211 to move downward, and the movement of the hydraulic cylinder 1 211 will cause the liquid in the two hydraulic cylinders 212 to be drawn into the hydraulic cylinder 1 211, and the reduction of the liquid in the hydraulic cylinder 212 will cause the two connecting plates 22 to shrink inward, so that the two sliding doors 23 are closed. When ascending, the staff only needs to continue standing on the moving block 21 to avoid accidentally opening the sliding door 23 and falling. At the same time, after leaving the moving block 21, the hydraulic cylinder 1 211 will move upward under the action of the spring 24, so that the liquid inside it enters the hydraulic cylinder 212. At this time, the two connecting plates 22 will drive the two sliding doors 23 to move in opposite directions. This component can not only perform automatic opening and closing, but also prevent the hidden danger of falling of the staff when ascending, thereby improving the overall safety of the device.

[0043] If the traction rope is disconnected or the device falls rapidly during the ascent, the rotating block 312 contacts the guide rail 13, which will drive the rotating column 31 and the spring hook 311 to rotate during the falling process. Due to the influence of gravity, the rotation speed of the rotating block 312 will increase. At the same time, the spring hook 311 will extend outward due to the centrifugal force. The extended spring hook 311 will be hung in the groove of the pulling rod 32 during the rotation. Since the moving range of the pulling rod 32 is limited, the rotating block 312 will stop rotating and produce friction with the guide rail 13, thereby slowing down the descent speed. Since the rotating deceleration block 34 is adjustable The pull rod 32 will pull the rotating ring 35 while moving so that it contacts the bottom of the rotating ring 35. Since the rotating ring 33 is restricted from rotating upward by the upper limit, the fixed deceleration block 331 will extend its longest end to the top of the rotating ring 35 under the pull of the pull rod 32, so that the rotating ring 35 is restricted and stopped, thereby increasing the friction between the rotating wheel 14 and the guide rail 13, and decelerating the device for a second time. At the same time, the device is stopped under the action of the stagnation component 5. Compared with some non-climbing devices, this device can automatically decelerate the device by using the centrifugal force during the fall when the staff cannot react in time, so as to avoid serious injuries to the staff due to untimely reaction and inability to operate in an emergency.

[0044] When the rotating block 1 312 rotates, the rotating block 2 41 will be driven to rotate through the fixed column 43. Since the spring hook 2 44 is shorter than the spring hook 1 311, it will not be hung and stopped first. The rotating block 1 312 is restricted when it is hung on the pulling rod 32 and will suddenly stop rotating. The rotating block 2 41 will continue to rotate under the influence of inertia under the action of the limit groove 411, so that the spring hook 2 44 is hung on the fixed tooth 45. Since the thorn gear 42 is fixed on the rotating block 1 312, the thorn gear 42 will also stop rotating when the rotating block 1 312 stops rotating. At this time, the rotating block 2 41 that continues to rotate due to inertia will drive The spring limit plate 421 moves while contacting the thorn gear 42, and the limit groove 411 and the spring limit plate 421 can limit the movable range of the rotating block 2 41, so that the reduction device 3 can be reinforced as a whole to prevent the spring hook 1 311 from suddenly stopping and shaking and shifting in the opposite direction when hanging on the pulling rod 32, causing the rotating block 1 312 to be unhooked. The component can use inertia to lock the reduction device 3, and can also bear part of the force exerted on the spring hook 1 311, thereby protecting the spring hook 1 311 and limiting the reduction component 3 to prevent the reduction failure caused by the unhooking of the rotating block 1 312.

[0045] The upward movement of the pull rod 32 can drive the telescopic cylinder 1 51 to move upward, so that the liquid inside it can be pushed into the delivery pipe 511. Since the delivery pipe 511 contains liquid, the excess liquid will be delivered to the diversion cylinder 52. The diversion cylinder 52 is connected to the two telescopic cylinders 2 521. The movement of the liquid will push the two friction plates 522 in opposite directions at the same time, causing friction between them and the guide rail 13. Since the device has been decelerated before, the friction force generated by the two friction plates 522 on the guide rail 13 will cause it to decelerate again and then stagnate, causing the device to decelerate again after deceleration until the device stops falling, thereby avoiding the problem that the decelerated device falls to the ground and may cause injuries to the staff. This not only ensures the safety of the staff, but also effectively protects the equipment.
