Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to an emergency device for a gate hoist. Background Art
[0002] As a key hydraulic machinery product, gate hoists play a vital role in the proper operation of hydraulic structures. Their primary function is to control the raising and lowering of various large cast iron and steel gates, enabling their opening and closing. During natural disasters, gate hoists can malfunction due to flooding, resulting in malfunctions. This can prevent the gates from opening smoothly, posing a safety hazard. Therefore, to ensure the proper operation of gate hoists in extreme conditions, they must be equipped with emergency devices.
[0003] Under normal operating conditions, the emergency device should remain separated from the gate hoist. When the gate hoist fails to work properly, the emergency device needs to be connected to the gate hoist and drive it to operate. In the prior art, the gate hoist and the emergency device are usually controlled by two independent circuits, and then when the emergency device is needed, it is connected to the gate hoist by electric control. Although this method is simple and fast to operate, when a disaster occurs, such as when a dam overflows or a canal overflows, it is difficult to ensure that the circuit system of the emergency device is not damaged. If the circuit of the emergency device fails, the gate hoist will not be driven to work, thereby making the purpose of setting up the emergency device fail to achieve. Summary of the Invention
[0004] In response to the defects of the existing technology, the technical problem to be solved by the utility model is to provide an emergency device for a gate opening and closing machine to ensure that the emergency device can still maintain its normal function in the event of an emergency such as a dam overflow or a canal overflow, effectively avoiding equipment failures caused by circuit failures or long-term non-use, and ensuring that the emergency device can drive the opening and closing machine to operate normally, thereby reducing safety risks.
[0005] In order to solve the above technical problems, the utility model proposes an emergency device for a gate hoist, which adopts the following technical solutions:
[0006] A gate opening and closing machine emergency device includes a driving device and a clutch device, one end of the clutch device is connected to the output shaft of the driving device and the other end is connected to the input shaft of the opening and closing machine, the output shaft of the driving device and the input shaft of the opening and closing machine are located on the same axis, the clutch device includes a first shaft sleeve assembly, a second shaft sleeve assembly and a positioning assembly, the first shaft sleeve assembly is slidingly connected to the output shaft of the driving device, the second shaft sleeve assembly is fixedly connected to the input shaft of the opening and closing machine, the first shaft sleeve assembly and the second shaft sleeve assembly slide in cooperation, the positioning assembly is fixedly set on the first shaft sleeve assembly, the positioning assembly includes a pushing member and a push rod, the pushing member is fixedly connected to the first shaft sleeve assembly, one end of the push rod is fixedly connected to the pushing member, the other end of the push rod is provided with a tightening device, a mounting plate is provided under the push rod, the push rod is connected to the mounting plate, and the mounting plate is fixedly connected to the driving device.
[0007] In this design, a specific mechanical structure is adopted and the synergistic effect of the push rod and the push member is utilized to cause the first sleeve assembly to move toward the second sleeve assembly, thereby achieving rapid docking of the two. During the specific operation, when the emergency device needs to start the gate hoist, the push rod is manually operated to drive the first sleeve assembly and the second sleeve assembly to dock. Once the docking is completed, the tightening device is applied to the push rod to firmly fix it on the mounting plate to ensure that the push rod does not move, thereby fixing the position of the first sleeve. Subsequently, the drive device is powered by an external power supply to enable the gate hoist to operate normally. This design ensures that in emergency situations such as dam overflow or canal overflow, the emergency device can still maintain normal function, avoiding the problem of equipment failure due to circuit failure or long-term non-use.
[0008] Furthermore, the push rod includes a horizontal rod and a vertical rod. The vertical rod is fixedly arranged at the end of the horizontal rod away from the pusher. The bottom of the vertical rod is connected to the mounting plate. A threaded through hole is provided in the axial direction of the vertical rod. The tightening device is a tightening bolt, which is threadedly connected to the threaded through hole. In this structure, the push rod can be displaced by manually loosening the tightening bolt; and tightening the tightening bolt can ensure that the push rod is fixed to the mounting plate. This design not only simplifies the assembly process, but also the threaded connection has good self-locking properties, and can maintain a stable connection state even in extreme environments. In addition, the structural design of the horizontal rod and the vertical rod effectively reduces the contact area between the push rod and the mounting plate, thereby increasing the contact pressure and further enhancing the fixing effect of the tightening bolt on the push rod, making it more difficult for the push rod to displace after being subjected to force.
[0009] Preferably, the first shaft sleeve assembly includes external teeth and an external-tooth shaft sleeve, and the external teeth are fixedly arranged at an end of the external-tooth shaft sleeve away from the driving device.
[0010] Preferably, the second sleeve assembly includes inner teeth and an inner tooth sleeve, wherein the inner teeth are fixedly mounted on an end of the inner tooth sleeve away from the gate hoist, and the outer teeth can mesh with the inner teeth under the drive of the driving device.
[0011] The meshing design of external and internal teeth ensures efficient power transmission from the drive unit to the gate hoist. Compared to other types of meshing transmission, meshing transmission offers higher transmission efficiency and greater load-bearing capacity, making it particularly suitable for applications requiring high torque output. Furthermore, the precise meshing of the internal and external teeth enables accurate axial positioning, which is particularly important for equipment requiring precise control of opening and closing movements. Furthermore, the sliding fit allows for fine-tuning within a certain range, helping to reduce unnecessary stress concentration and further protecting components from damage.
[0012] Preferably, a first keyway is provided inside the outer gear sleeve, a first connecting key is provided on the output shaft of the driving device, the first keyway extends to the edge of the outer gear sleeve at one end away from the outer teeth, the first keyway and the first connecting key are slidingly matched, a second keyway is provided inside the inner gear sleeve, a second connecting key is provided on the input shaft of the gate opening and closing machine, and the second connecting key is fixedly matched with the second keyway. The matching design of the keyway and the key can effectively transmit large torque, especially in applications requiring high torque output. This design can ensure efficient power transmission and reduce energy loss. The sliding fit of the first connecting key and the first keyway ensures the axial positioning between the outer gear sleeve and the output shaft of the driving device, prevents axial movement, and improves the accuracy of transmission. The fixed fit of the second connecting key and the second keyway ensures a firm connection between the inner gear sleeve and the input shaft of the gate opening and closing machine, prevents relative rotation, and ensures stable power transmission.
[0013] Preferably, a support shaft is fixedly mounted on the mounting plate, and the middle portion of the crossbar is rotatably connected to the support shaft. The support shaft is fixed to the mounting plate, providing a stable fulcrum for the crossbar, ensuring the stability and reliability of the crossbar during movement, thereby helping to reduce shaking and vibration of the crossbar and improving the stability of the entire structure.
[0014] Preferably, a rubber sleeve is provided at the bottom of the jacking bolt. When the jacking bolt tightens the push rod against the mounting plate, the presence of the rubber sleeve can increase the friction between the jacking bolt and the mounting plate, thereby further enhancing the fixing effect and preventing the first sleeve assembly from shifting during operation of the device.
[0015] In summary, this gate hoist emergency device ensures that in the event of an emergency such as a dam overflow or a canal overflow, the emergency device can still maintain its normal function, effectively avoiding equipment failures caused by circuit failures or long-term disuse, and ensuring that the emergency device can drive the gate hoist to operate normally, thereby reducing safety risks.

DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1 and Figure 2 The gate hoist emergency device shown in the figure includes a driving device 1 and a clutch device 2. One end of the clutch device 2 is connected to the output shaft of the driving device 1 and the other end is connected to the input shaft of the hoist 3. The output shaft of the driving device 1 and the input shaft of the hoist 3 are located on the same axis. The clutch device 2 includes a first shaft sleeve assembly 21, a second shaft sleeve assembly 22 and a positioning assembly 23. The first shaft sleeve assembly 21 is slidably connected to the output shaft of the driving device 1, and the second shaft sleeve assembly 22 is fixedly connected to the input shaft of the hoist 3. Then, the first shaft sleeve assembly 21 and the second shaft sleeve assembly 22 are slidably matched, and the positioning assembly 23 is fixedly set on the first shaft sleeve assembly 21. The positioning assembly 23 includes a pushing member 231 and a push rod 232. The pushing member 231 is fixedly connected to the first shaft sleeve assembly 21, and one end of the push rod 232 is fixedly connected to the pushing member 231. The other end of the push rod 232 is provided with a tightening device 233. A mounting plate 4 is provided under the push rod 232. The push rod 232 is connected to the mounting plate 4, and the mounting plate 4 is fixedly connected to the driving device 1.
[0023] In this design, by adopting a specific mechanical structure, the synergistic effect of the push rod 232 and the push member 231 is utilized to prompt the first sleeve assembly 21 to move toward the second sleeve assembly 22, thereby achieving rapid docking of the two. During the specific operation, when the emergency device needs to start the gate hoist 3, the push rod 232 is manually operated to drive the first sleeve assembly 21 and the second sleeve assembly 22 to dock. Once the docking is completed, the tightening device 233 is applied to the push rod 232 to firmly fix it on the mounting plate 4 to ensure that the push rod 232 does not move, thereby fixing the position of the first sleeve. Subsequently, the drive device 1 is powered by an external power supply to enable the gate hoist 3 to operate normally. This design ensures that in emergency situations such as dam overflow or canal overflow, the emergency device can still maintain normal function, avoiding the problem of equipment failure due to circuit failure or long-term non-use.
[0024] Further, such as Figure 2 As shown, push rod 232 comprises a horizontal rod 2321 and a vertical rod 2322. Vertical rod 2322 is fixedly mounted at the end of horizontal rod 2321 away from pusher 231. The bottom of vertical rod 2322 is connected to mounting plate 4. A threaded through-hole 2323 is axially defined in vertical rod 2322. The tightening device 233 comprises a tightening bolt 234, which is threadedly engaged with threaded through-hole 2323. In this structure, manually loosening tightening bolt 234 allows push rod 232 to be moved; tightening tightening bolt 234 secures push rod 232 to mounting plate 4. This design not only simplifies assembly, but also provides the threaded connection with excellent self-locking properties, maintaining a stable connection even in extreme environments. In addition, the structural design of the horizontal bar 2321 and the vertical bar 2322 effectively reduces the contact area between the push rod 232 and the mounting plate 4, thereby increasing the contact pressure and further enhancing the fixing effect of the tightening bolt 234 on the push rod 232, making it more difficult to move after being subjected to force.
[0025] As a preference, Figure 3 As shown, the first shaft sleeve assembly 21 includes external teeth 211 and an external gear shaft sleeve 212 , and the external teeth 211 are fixedly arranged at an end of the external gear shaft sleeve 212 away from the driving device 1 .
[0026] Preferably, the second sleeve assembly 22 includes an inner tooth 221 and an inner tooth sleeve 222 , the inner tooth 221 is fixedly mounted on the end of the inner tooth sleeve 222 away from the gate hoist 3 , and the outer tooth 211 can engage with the inner tooth 221 under the drive of the drive device 1 .
[0027] The meshing design of the external teeth 211 and the internal teeth 221 ensures efficient power transmission from the drive unit 1 to the gate hoist 3. Compared to other transmission methods, meshing transmission offers higher transmission efficiency and greater load-bearing capacity, making it particularly suitable for applications requiring high torque output. Furthermore, the precise meshing of the internal and external teeth 211 enables accurate axial positioning, which is particularly important for equipment requiring precise control of opening and closing movements. Furthermore, the sliding fit allows for fine-tuning within a certain range, helping to reduce unnecessary stress concentration and further protecting components from damage.
[0028] As a preference, Figure 3 As shown, a first keyway 213 is provided inside the external gear sleeve 212, a first connecting key 11 is provided on the output shaft of the drive device 1, the first keyway 213 extends to the edge of the end of the external gear sleeve 212 away from the external teeth 211, the first keyway 213 and the first connecting key 11 are slidably fitted, a second keyway 223 is provided inside the internal gear sleeve 222, a second connecting key 31 is provided on the input shaft of the gate opening machine 3, and the second connecting key 31 is fixedly fitted with the second keyway 223. The matching design of the keyway and the key can effectively transmit large torque, especially in applications requiring high torque output. This design can ensure efficient transmission of power and reduce energy loss. The sliding fit of the first connecting key 11 and the first keyway 213 ensures the axial positioning between the external gear sleeve 212 and the output shaft of the drive device 1, prevents axial movement, and improves the accuracy of transmission. The fixed fit between the second connecting key 31 and the second keyway 223 ensures a firm connection between the internal gear sleeve 222 and the input shaft of the gate hoist 3, prevents relative rotation, and ensures stable transmission of power.
[0029] As a preference, Figure 2 As shown, a support shaft 41 is fixedly provided on the mounting plate 4, and the middle portion of the crossbar 2321 is rotatably connected to the support shaft 41. The support shaft 41 is fixed to the mounting plate 4, providing a stable fulcrum for the crossbar 2321, ensuring the stability and reliability of the crossbar 2321 during movement, which helps to reduce the shaking and vibration of the crossbar 2321 and improve the stability of the entire structure.
[0030] Preferably, a rubber sleeve is provided at the bottom of the jacking bolt 234. When the jacking bolt 234 presses the push rod 232 against the mounting plate 4, the presence of the rubber sleeve can increase the friction between the jacking bolt 234 and the mounting plate 4, thereby further enhancing the fixing effect and preventing the first shaft sleeve assembly 21 from shifting during operation of the equipment.
[0031] In summary, this gate hoist emergency device ensures that in the event of an emergency such as a dam overflow or a canal overflow, the emergency device can still maintain its normal function, effectively avoiding equipment failures caused by circuit failures or long-term disuse, and ensuring that the emergency device can drive the gate hoist to operate normally, thereby reducing safety risks.
