Description

Technical Field

[0001] This utility model belongs to the field of winch technology, and in particular relates to a double-suspended closed winch. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects. In water conservancy projects, gates are typically installed at dams to control water flow. Currently, winches are mainly used to lift and lower these gates. One end of the steel wire rope is connected to the upper end of the gate, and the winch is usually driven by a motor. However, in the event of a power outage or motor failure, the winch becomes unusable, affecting the normal opening and closing of the gate and potentially leading to safety accidents and significant economic losses. Utility Model Content

[0003] To solve the above problems, this utility model provides a double-suspension closed winch.

[0004] This utility model is implemented as follows: A double-suspension closed winch includes a first base frame and a second base frame. A first bearing seat is vertically fixed on one side of the upper end of the first base frame. A first roller is mounted on the first base frame. A first shaft at one end of the first roller passes through the center of the bearing inside the first bearing seat and is fixedly connected to the bearing. The first bearing seat limits the position of the first roller and ensures its smooth rotation. Second bearing seats are vertically and symmetrically fixed on both sides of the upper end of the second base frame. A second roller is mounted on the second base frame. Second shafts at both ends of the second roller pass through the center of the bearing inside the second bearing seat and are fixedly connected to the bearing. The second bearing seats limit the position of the second roller and ensure its smooth rotation. Steel wire ropes are wound on both the first and second rollers. A housing is fixedly mounted on the upper end of the first base frame. A transmission mechanism is installed inside the housing. The transmission mechanism includes a driving sprocket and a driven sprocket, which are tightly connected. A chain is wound around the first roller. The rotation of the drive sprocket drives the rotation of the driven sprocket via the chain. The first bearing housing corresponds to the position of the driven sprocket. The first shaft at the other end of the first roller passes through the center hole of the bearing on the housing and the center hole of the driven sprocket, and is connected to one end of the second shaft via a connecting rod. This ensures the stability of the first roller's position and connects the first and second rollers together via the connecting rod. A motor and a reducer are fixedly mounted on the upper end of the first base frame on one side of the first roller. The drive shaft of the motor is connected to the input shaft of the reducer. A third shaft is horizontally and symmetrically fixed at the middle of both ends of the drive sprocket. The output shaft of the reducer is connected to the end of the third shaft. The motor drives the first and second rollers to rotate, and the reducer is used to reduce the speed of the first and second rollers, thereby ensuring smooth lifting and lowering of the gate. The motor drives the drive sprocket to rotate, which in turn drives the driven sprocket via the chain, and then drives the first and second rollers to rotate via the first shaft and connecting rod.

[0005] A housing is fixedly mounted on the upper end of the first base frame on the side of the housing away from the motor, protecting the internal components. An emergency hydraulic motor and an emergency hydraulic diesel pump station are fixedly mounted on the first base frame on the other side of the housing. In the event of a power outage or motor failure, the emergency hydraulic motor or emergency hydraulic diesel pump station can drive the first and second rollers to rotate, completing the normal opening and closing process of the gate. The end of the third shaft is located inside the housing, and a first gear is fixedly mounted on the third shaft. A first transmission rod and a second transmission rod are horizontally symmetrically arranged on both sides of the third shaft, passing through the bearing on the side wall of the housing. A second gear is fixedly mounted on the first transmission rod. The output shaft of the emergency hydraulic motor is connected to the end shaft of the first transmission rod. A movable first linkage rod is provided between the third shaft and the first transmission rod. A third gear is fixedly mounted on the end of the first linkage rod. The positions of the first, second, and third gears are corresponding and can mesh together. Pushing the first linkage rod causes the third gear to extend into the first and second gears. The gears are reliably meshed together. When the emergency hydraulic motor is started, the first transmission rod rotates, which in turn rotates the second gear. The third gear drives the first gear to rotate, which in turn drives the drive sprocket to rotate via the third shaft. A fourth gear is fixedly installed on the second transmission rod. The output shaft of the emergency hydraulic diesel pump station is connected to the end shaft of the second transmission rod. A movable second linkage rod is provided between the third shaft and the second transmission rod. A fifth gear is fixedly installed at the end of the second linkage rod. The positions of the first, fourth, and fifth gears are corresponding and can mesh together. Pushing the second linkage rod causes the fifth gear to extend between the first and fourth gears and reliably mesh together. When the emergency hydraulic diesel pump station is started, the second transmission rod rotates, which in turn rotates the fourth gear. The fifth gear drives the first gear to rotate, which in turn drives the drive sprocket to rotate via the third shaft. A lifting mechanism is provided below both the first and second base frames. The first and second rollers drive the gate to move up and down through the lifting mechanism.

[0006] Preferably, a first limiting ring is fixedly installed inside the housing. The first transmission rod and the second transmission rod pass through the central hole of the first limiting ring. The diameters of the first transmission rod and the second transmission rod are the same as the inner diameter of the first limiting ring. The first limiting ring limits the position of the first transmission rod and the second transmission rod to prevent the first transmission rod and the second transmission rod from shifting position, thereby ensuring the stability of the position of the second gear and the fourth gear.

[0007] Preferably, a second limiting ring is fixedly installed inside the housing. The first and second linkage rods pass through the central hole of the second limiting ring. The diameters of the first and second linkage rods are the same as the inner diameter of the second limiting ring. The second limiting ring limits the position of the first and second linkage rods, preventing them from shifting position. This ensures that the third gear can reliably extend between the first and second gears and that the fifth gear can reliably extend between the first and fourth gears.

[0008] Preferably, the ends of the first linkage rod and the second linkage rod located outside the housing are fixedly provided with pull handles to facilitate pushing and pulling movements of the first linkage rod and the second linkage rod.

[0009] Preferably, a retaining strip is fixedly provided on the first shaft, the retaining strip is arranged parallel to the first shaft, and a retaining groove is provided at the center hole of the driven sprocket. The retaining strip and the retaining groove are positioned correspondingly and are the same size. The retaining strip passes through the retaining groove to ensure a reliable connection between the first shaft and the driven sprocket, thereby ensuring that the driven sprocket drives the first shaft to rotate, and then drives the first roller to rotate.

[0010] Preferably, the reducer is a planetary reducer, which has a good deceleration effect.

[0011] The beneficial effects of this utility model are as follows: When a power outage or motor failure occurs, the first linkage rod can be pushed to make the third gear extend between the first gear and the second gear and reliably mesh together, and then the emergency hydraulic motor can be started. Alternatively, the second linkage rod can be pushed to make the fifth gear extend between the first gear and the fourth gear and reliably mesh together, and then the emergency hydraulic diesel pump station can be started. By starting the emergency hydraulic motor or the emergency hydraulic diesel pump station, the first roller and the second roller are driven to rotate, thus completing the normal opening and closing process of the gate in a timely manner and avoiding the occurrence of safety accidents and economic losses.

[0016] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0017] like Figure 1-3The double-suspension closed winch shown includes a first base frame 1 and a second base frame 2. A first bearing seat 3 is vertically fixed on one side of the upper end of the first base frame 1. A first drum 4 is mounted on the first base frame 1. A first shaft 5 at one end of the first drum 4 passes through the center of the bearing inside the first bearing seat 3 and is fixedly connected to the bearing. The first bearing seat 3 limits the position of the first drum 4 and ensures its smooth rotation. Second bearing seats 6 are vertically and symmetrically fixed on both sides of the upper end of the second base frame 2. A second drum 7 is mounted on the second base frame 2. Second shafts 8 at both ends of the second drum 7 pass through the center of the bearing inside the second bearing seat 6 and are fixedly connected to the bearing. The second bearing seats 6 limit the position of the second drum 7 and ensure its smooth rotation. Steel wire ropes 9 are wound on both the first drum 4 and the second drum 7. A housing 10 is fixedly mounted on the upper end of the first base frame 1. A transmission mechanism 11 is installed inside the housing 10. The structure 11 includes a drive sprocket 12 and a driven sprocket 13. A chain 14 is tightly wound on the drive sprocket 12 and the driven sprocket 13. When the drive sprocket 12 rotates, it drives the driven sprocket 13 to rotate through the chain 14. The first bearing seat 3 is positioned corresponding to the driven sprocket 13. The first shaft 5 at the other end of the first roller 4 passes through the center of the bearing on the housing 10 and the center hole of the driven sprocket 13 in sequence, and is connected to one end of the second shaft 8 through the connecting rod 15. This ensures the stability of the position of the first roller 4 and connects the first roller 4 and the second roller 7 together through the connecting rod 15. A motor 16 and a reducer 17 are fixedly installed on the upper end of the first base frame 1 on one side of the first roller 4. The drive shaft of the motor 16 is connected to the input shaft of the reducer 17. A third shaft 18 is horizontally and symmetrically fixed at the middle position of both ends of the drive sprocket 12. The output shaft of the reducer 17 is connected to the end shaft of the third shaft 18. The reducer 17 is a planetary reducer with good deceleration effect. The motor 16 drives the first roller 4 and the second roller 7 to rotate. The reducer 17 is used to reduce the speed of the first roller 4 and the second roller 7, thereby ensuring smooth lifting and lowering of the gate. The motor 16 drives the drive sprocket 12 to rotate, which in turn drives the driven gear 13 to rotate through the chain 14, and then drives the first roller 4 and the second roller 7 to rotate through the first shaft 5 and the connecting rod 15.

[0018] A housing 19 is fixedly mounted on the upper end of the first base frame 1 on the side of the housing 10 away from the motor 16 to protect the internal components. An emergency hydraulic motor 20 and an emergency hydraulic diesel pump station 21 are fixedly mounted on the first base frame 1 on the other side of the housing 19. In the event of a power outage or a failure of the motor 16, the first roller 4 and the second roller 7 can be rotated by the emergency hydraulic motor 20 or the emergency hydraulic diesel pump station 21 to complete the normal opening and closing process of the gate. The end of the third shaft 18 is located inside the housing 19, and a first gear 22 is fixedly mounted on the third shaft 18, passing through a bearing on the side wall of the housing 19. Furthermore, a first transmission rod 23 and a second transmission rod 24 are horizontally symmetrically arranged on both sides of the third shaft 18. A first limiting ring 31 is fixedly installed inside the housing 19. The first transmission rod 23 and the second transmission rod 24 pass through the central hole of the first limiting ring 31. The diameters of the first transmission rod 23 and the second transmission rod 24 are the same as the inner diameter of the first limiting ring 31. The first limiting ring 31 limits the position of the first transmission rod 23 and the second transmission rod 24 to prevent the first transmission rod 23 and the second transmission rod 24 from shifting their positions, thereby ensuring the stability of the positions of the second gear 25 and the fourth gear 28. A second gear 25 is fixedly mounted on the first transmission rod 23. The output shaft of the emergency hydraulic motor 20 is connected to the end shaft of the first transmission rod 23. A movable first linkage rod 26 is provided between the third shaft 18 and the first transmission rod 23. A third gear 27 is fixedly mounted on the end of the first linkage rod 26. The positions of the first gear 22, the second gear 25, and the third gear 27 are corresponding and can mesh together. Pushing the first linkage rod 26 causes the third gear 27 to extend between the first gear 22 and the second gear 25 and reliably mesh together, starting the emergency hydraulic motor 20. The first transmission rod 23 rotates accordingly, and then the second gear 25 rotates. The third gear 27 drives the first gear 22 to rotate, which in turn drives the drive sprocket 12 to rotate via the third shaft 18. A second transmission rod 24 is fixedly mounted on... The emergency hydraulic diesel pump station 21 has a fourth gear 28. The output shaft of the emergency hydraulic diesel pump station 21 is connected to the end shaft of the second transmission rod 24. A movable second linkage rod 29 is provided between the third shaft 18 and the second transmission rod 24. A second limiting ring 32 is fixedly provided inside the housing 19. The first linkage rod 26 and the second linkage rod 29 pass through the central hole of the second limiting ring 32. The diameters of the first linkage rod 26 and the second linkage rod 29 are the same as the inner diameter of the second limiting ring 32. The second limiting ring 32 limits the position of the first linkage rod 26 and the second linkage rod 29 to prevent the first linkage rod 26 and the second linkage rod 29 from shifting position. This ensures that the third gear 27 can reliably extend between the first gear 22 and the second gear 25 and that the fifth gear 30 can reliably extend between the first gear 22 and the fourth gear 28.A fifth gear 30 is fixedly installed at the end of the second linkage rod 29. The positions of the first gear 22, the fourth gear 28 and the fifth gear 30 are corresponding and can mesh together. Pushing the second linkage rod 29 causes the fifth gear 30 to extend between the first gear 22 and the fourth gear 28 and mesh reliably together. The emergency hydraulic diesel pump station 21 is started, and the second transmission rod 24 rotates accordingly. Then the fourth gear 28 rotates, which drives the first gear 22 to rotate through the fifth gear 30. Subsequently, the third shaft rod 18 drives the drive sprocket 12 to rotate. A lifting mechanism is provided below the first base frame 1 and the second base frame 2. The first roller 4 and the second roller 7 drive the gate to move up and down through the lifting mechanism.

[0019] A handle 33 is fixedly provided at the end of the first linkage rod 26 and the second linkage rod 29 located outside the housing 19, so as to facilitate the pushing and pulling movement of the first linkage rod 26 and the second linkage rod 29.

[0020] A retaining strip 34 is fixedly installed on the first shaft 5. The retaining strip 34 is arranged parallel to the first shaft 5. A retaining groove 35 is provided at the center hole of the driven sprocket 13. The retaining strip 34 and the retaining groove 35 are positioned correspondingly and are the same size. The retaining strip 34 passes through the retaining groove 35 to ensure a reliable connection between the first shaft 5 and the driven sprocket 13, thereby ensuring that the driven sprocket 13 drives the first shaft 5 to rotate, and then drives the first roller 4 to rotate.

[0021] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
