Description

Technical Field

[0001] The present invention relates to the technical field of energy recovery of hydraulic devices, and more particularly to an energy-recoverable hydraulic transmission device. Background Art

[0002] The practical application of existing hydraulic transmission devices presents a particularly challenging problem: even after the device completes the braking action, the oil in the system continues to flow into the hydraulic transmission device. This phenomenon directly interferes with the accuracy of the hydraulic transmission process, causing deviations in the device's output precision, which in turn affects the overall system's performance. In stark contrast, hydraulic transmission devices equipped with energy recovery devices demonstrate significant advantages. During braking and deceleration, such devices can quickly pressurize the system's high-pressure oil into the accumulator. This action acts like a "pause" button on the device, promptly terminating the hydraulic transmission's continuous operation and effectively avoiding the accuracy issues caused by the continuous oil injection.

[0003] However, existing hydraulic transmissions suffer from another significant operational flaw: a lack of protective structures. If a hydraulic transmission fails or becomes damaged, the connected structure can rapidly fall off. This unforeseen situation can not only severely damage connected equipment, increasing repair and replacement costs, but more importantly, pose a potential threat to the safety of on-site operators and create significant safety hazards for the entire work environment. To address this, we propose a hydraulic transmission with energy recovery. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention designs a pressure assembly, a recovery assembly and a rotating assembly. When an unexpected situation occurs, the hydraulic rod is unable to continue to support, or the pressure in the hydraulic cylinder is insufficient or a leak occurs, the hydraulic rod will fall rapidly due to insufficient pressure. At this time, the hydraulic rod pushes the extrusion rod to slide quickly into the pressure assembly, and the pressure suddenly increases, making it difficult for the extrusion rod to push the non-Newtonian fluid in the pressure assembly, thereby pushing the pressure assembly as a whole to drive the first gear plate downward. The first gear plate will drive the rotating assembly to rotate at high speed. The high-speed rotating rotating assembly engages with the adjusting assembly, and drives the adjusting assembly upward when the rotating assembly rotates, discharging the high-pressure oil collected in the recovery assembly, thereby supporting the pressure assembly. In this way, the device can automatically support the hydraulic rod when encountering an emergency, avoid further damage to the device due to the emergency, reduce economic losses, and at the same time ensure personnel safety, thereby improving the safety of using the device.

[0017] 2. The present invention also designs a base assembly. When an external hydraulic pump injects high-pressure oil into the connector, the high-pressure oil will flow rapidly along the liquid inlet hole in the base. After passing through the control valve set in the liquid inlet hole, the oil enters the hydraulic cylinder, thereby pushing the hydraulic rod upward to complete the adjustment of the adjustment head position. When it is necessary to stop the movement of the adjustment head, the control valve in the liquid inlet hole is directly closed, the control valve in the tap hole is opened, and the external hydraulic pump is turned off. At this time, the residual hydraulic oil will flow into the two pressure cylinders along the tap hole. In this way, the device can stably recover energy while avoiding the position of the adjustment head being affected by the residual high-pressure oil, thereby improving the adjustment accuracy of the device.

[0018] 3. The present invention also designs an adjustment component. After use, the high-pressure oil is returned through the return hole. At this time, the height of the hydraulic rod drops, and then the extrusion rod is driven to slide in the sealing cylinder through the fixed frame. When sliding to the extreme position, the extrusion rod will drive the sealing plate and the first tooth plate to move downward. Since the first tooth plate descends slowly at this time, it is difficult to drive the rotating drum to rotate at high speed, resulting in the shift block being unable to slide out smoothly. At the same time, because the extrusion rod descends slowly, it can push the non-Newtonian fluid into the connecting cylinder, thereby ensuring the stability of the device under normal use.

[0021] like Figures 1 to 8 As shown, the present invention relates to an energy-recoverable hydraulic transmission device, comprising a hydraulic cylinder 12, a connector 13 and a hydraulic rod 14, and further comprising: The hydraulic transmission mechanism 1 includes a base assembly 11, a hydraulic cylinder 12 connected to the base assembly 11, a connector 13 connected to the base assembly 11, a hydraulic rod 14 and an adjusting head 15, wherein the hydraulic rod 14 is located in the hydraulic cylinder 12, and the adjusting head 15 is fixedly connected to the top of the hydraulic rod 14; and an energy recovery mechanism 2, including a fixed frame 21, two connecting rods 22 located below the fixed frame 21, two reinforcing ribs 23 connected to the two connecting rods 22, an extrusion rod 24 located below the reinforcing rib 23, a pressure assembly 25 located outside the extrusion rod 24, a recovery assembly 26, an adjusting assembly 27 located inside the recovery assembly 26, a rotating assembly 28 connected to the adjusting assembly 27, a first tooth plate 29 connected to the rotating assembly 28, and the recovery assembly 26 is located below the pressure assembly 25. By designing the pressure assembly 25, the recovery assembly 26 and the rotating assembly 28, when an accident occurs, resulting in the hydraulic rod 1 When it is difficult to continue supporting, or when the pressure in the hydraulic cylinder 12 is insufficient or a leak occurs, the hydraulic rod 14 will fall rapidly due to insufficient pressure. At this time, the hydraulic rod 14 pushes the extrusion rod 24 to slide quickly into the pressure assembly 25. The pressure suddenly increases, making it difficult for the extrusion rod 24 to push the non-Newtonian fluid in the pressure assembly 25, thereby pushing the pressure assembly 25 as a whole to drive the first tooth plate 29 downward. The first tooth plate 29 will drive the rotating assembly 28 to rotate at high speed. The high-speed rotating rotating assembly 28 engages with the adjusting assembly 27. When the rotating assembly 28 rotates, it drives the adjusting assembly 27 upward to discharge the high-pressure oil collected in the recovery assembly 26, thereby supporting the pressure assembly 25. In this way, the device can automatically support the hydraulic rod 14 when encountering an emergency, avoiding the expansion of damage to the device due to the emergency, reducing economic losses, and at the same time ensuring the safety of personnel, thereby improving the safety of using the device.

[0022] In an embodiment of the present invention, the top of the base assembly 11 is connected to the hydraulic cylinder 12, and the top of the base assembly 11 is connected to the bottom end of the connector 13. A hydraulic rod 14 is slidably connected in the hydraulic cylinder 12, and the top of the hydraulic rod 14 is fixedly connected to the adjusting head 15. The bottom of the fixed frame 21 is fixedly connected to the top of the two connecting rods 22, and the bottom ends of the connecting rods 22 are respectively fixedly connected to the tops of the two reinforcing ribs 23, and the bottom ends of the two reinforcing ribs 23 are respectively fixedly connected to the two extrusion rods 24, and the two extrusion rods 24 are respectively slidably connected in the two pressure assemblies 25, and the bottom end of the pressure assembly 25 is slidably connected in the recovery assembly 26. The bottom end of the pressure assembly 25 is fixedly connected to the first tooth plate 29, and the first tooth plate 29 is meshed with the rotating assembly 28, and the rotating assembly 28 is meshed with the adjusting assembly 27. The adjusting assembly 27, the rotating assembly 28 and the first tooth plate 29 are all located in the recovery assembly 26. 21 is fixedly connected to the outside of the hydraulic rod 14, and the two recovery components 26 are fixedly connected to the top of the base component 11. Through the design of the base component 11, when the external hydraulic pump injects high-pressure oil into the connector 13, the high-pressure oil will flow rapidly along the liquid inlet hole 112 in the base 111. After passing through the control valve 115 set in the liquid inlet hole 112, the oil enters the hydraulic cylinder 12, thereby pushing the hydraulic rod 14 to move upward, completing the adjustment of the position of the regulating head 15. When it is necessary to stop the movement of the regulating head 15, the control valve 115 in the liquid inlet hole 112 is directly closed, the control valve 115 in the tap hole 114 is opened, and the external hydraulic pump is turned off. At this time, the residual hydraulic oil will flow into the two pressure cylinders 261 along the tap hole 114. In this way, the device can stably recover energy while avoiding the influence of the residual high-pressure oil on the position of the regulating head 15, thereby improving the adjustment accuracy of the device.

[0023] In an embodiment of the present invention, the base assembly 11 includes a base 111, a liquid inlet hole 112 and a return hole 113 are opened in the base 111, the liquid inlet hole 112 and the return hole 113 are both provided with a spring and a sealing steel ball, the liquid inlet hole 112 is connected to the tap hole 114, and a control valve 115 is provided in the liquid inlet hole 112 and the tap hole 114. The hydraulic cylinder 12 is fixedly connected to the top of the base 111, and the hydraulic cylinder 12 is connected to the base 111 through the liquid inlet hole 112 and the return hole 113. The recovery component 26 is fixedly connected to the top of the base 111, and the recovery component 26 is connected to the base 111 through the tap hole 114. By designing the adjustment component 27, after use, the high-pressure oil is returned through the return hole 113. At this time, the hydraulic rod 14 drops in height, and then drives the extrusion rod 24 to slide in the sealing cylinder 251 through the fixed frame 21. When sliding to the extreme position, the extrusion rod 24 will drive the sealing plate 257 and the first tooth plate 29 to move downward. Since the first tooth plate 29 descends slowly at this time, it is difficult to drive the rotating cylinder 283 to rotate at a high speed, resulting in the shift block 286 being unable to slide out smoothly. At the same time, because the extrusion rod 24 descends slowly, it can push the non-Newtonian fluid into the connecting cylinder 253, thereby ensuring the stability of the device under normal use.

[0024] As another embodiment of the present invention, the pressure assembly 25 includes a sealing cylinder 251, one side of the sealing cylinder 251 is connected to the connecting cylinder 253 through an inclined tube 252, an inclined groove 254 is provided at the bottom of the inner wall of the connecting cylinder 253, and a leak-proof valve 255 is provided at the top of the connecting cylinder 253. A sealing gasket 256 is slidably connected in the sealing cylinder 251. The sealing cylinder 251 and the connecting cylinder 253 are fixedly connected to the top of the sealing plate 257. Non-Newtonian fluid is provided in the sealing cylinder 251 and the connecting cylinder 253. The top of the sealing gasket 256 is fixed to the bottom end of the extrusion rod 24. The sealing plate 257 is connected in a sliding manner in the recovery component 26. The lower part of the sealing plate 257 is fixedly connected to the first tooth plate 29. The recovery component 26 includes a slide groove 262 on the upper part of the pressure cylinder 261. The inner wall of the pressure cylinder 261 is fixedly connected to the isolation plate 263. The upper part of the isolation plate 263 is fixedly connected with a drain pipe 264. The isolation plate 263 is connected to the drain pipe 264. The sealing plate 257 is connected in a sliding manner in the slide groove 262. The slide groove 262 is provided with an anti-slip groove. When an accident occurs, the hydraulic rod 14 cannot obtain the high pressure in the hydraulic cylinder 12. When the hydraulic oil is supported, the hydraulic rod 14 will fall rapidly. At this time, the hydraulic rod 14 quickly drives the extrusion rod 24 to move downward through the fixed frame 21. Since the extrusion rod 24 quickly squeezes the sealing gasket 256 and the non-Newtonian fluid in the connecting cylinder 253, it is difficult to squeeze the non-Newtonian fluid into the sealing cylinder 251. Therefore, the connecting cylinder 253 squeezes the sealing plate 257, causing it to push the first tooth plate 29 to fall rapidly in the slide groove 262. Since the first tooth plate 29 falls very quickly, the tooth block 284 and the rotating cylinder 283 connected thereto will also rotate at high speed. Under the action of the centrifugal force, the shift block 286 flips out along the pin shaft 285. At this time, the rotating cylinder 283 drives the second tooth plate 271 to move upward through the shift block 286. The upward movement of the second tooth plate 271 drives the sealing partition 273 to separate from the drain pipe 264. Therefore, the high-pressure oil located below the pressure cylinder 261 can quickly pass through the isolation plate 263 and the drain pipe 264 and enter the top of the pressure cylinder 261, thereby pushing the sealing plate 257 to remain in place, completing the secondary utilization of the recovered energy. At the same time, this process can also ensure the safety of personnel and the safe use of the device.

[0025] As another embodiment of the present invention, the adjusting component 27 includes a second tooth plate 271, and a sealing partition 273 is fixedly connected to the bottom of the second tooth plate 271. The sealing partition 273 is L-shaped, and the bottom of the sealing partition 273 is fixedly connected to the top of the elastic telescopic rod 272. The bottom end of the elastic telescopic rod 272 is fixedly connected to the top of the isolation plate 263. One side of the sealing partition 273 overlaps with one end of the drain pipe 264, and the sealing partition 273 has a sealing effect on the drain pipe 264. The rotating component 28 includes two bearings 281, and the same rotating shaft 282 is sleeved in the two bearings 281. The rotating shaft 282 is fixedly connected to a rotating drum 283 on the outside, and the rotating drum 283 is fixedly connected to a plurality of tooth blocks 28 4, and one side of several tooth blocks 284 is clamped with a pin shaft 285, and the tooth block 284 is hinged to the shift block 286 through the pin shaft 285. A coil spring 287 is provided outside the pin shaft 285, and the two ends of the coil spring 287 are fixedly connected to the shift block 286 and the tooth block 284 respectively. The tooth block 284 is engaged with the first tooth plate 29, and the two bearings 281 are clamped in the pressure assembly 25. The lower part of the first tooth plate 29 is fixedly connected to the isolation plate 263 through a strong spring. Because an anti-slip groove is provided, when the hydraulic rod 14 moves upward and thus pulls the extrusion rod 24 and the pressure assembly 25 upward, the anti-slip groove can prevent the sealing plate 257 from falling off from the slide groove 262, thereby ensuring the safety of the device when in use.

[0026] Working Principle: This embodiment provides a hydraulic transmission device with energy recovery. When in use, the device is connected to an external power element, a hydraulic pump, via a connector 13. The hydraulic pump injects high-pressure oil into the connector 13. The high-pressure oil flows along the base assembly 11 into the hydraulic cylinder 12, thereby pushing the hydraulic rod 14 upward. At the same time, the hydraulic rod 14 drives the connecting rod 22 and the extrusion rod 24 to move through the fixing frame 21. When it is necessary to stop the movement of the hydraulic rod 14, a shutdown signal is input, and the hydraulic pump stops running. At this time, the high-pressure oil that fails to enter the hydraulic cylinder 12 in time will quickly enter the recovery assembly 26. If an unexpected situation occurs, causing the hydraulic rod 14 to be unable to continue supporting, or the pressure in the hydraulic cylinder 12 is insufficient or a leak occurs, the hydraulic rod 14 will fall rapidly due to insufficient pressure. At this time, the hydraulic rod 14 pushes the extrusion rod 24 to slide quickly into the pressure assembly 25, and the pressure suddenly increases, making it difficult for the extrusion rod 24 to push the non-Newtonian fluid in the pressure assembly 25, thereby pushing the pressure assembly 25 as a whole to drive the first gear plate 29 downward. The first gear plate 29 will drive the rotating assembly 28 to rotate at high speed. The high-speed rotating rotating assembly 28 engages with the adjusting assembly 27. When the rotating assembly 28 rotates, it drives the adjusting assembly 27 to move upward, thereby discharging the high-pressure oil collected in the recovery assembly 26, and supporting the pressure assembly 25. When the external hydraulic pump injects high-pressure oil into the connector 13, the high-pressure oil will flow rapidly along the liquid inlet hole 112 in the base 111, pass through the control valve 115 in the liquid inlet hole 112, and then enter the hydraulic cylinder 12, thereby pushing the hydraulic rod 14 upward to complete the adjustment of the position of the adjustment head 15. When it is necessary to stop the movement of the adjustment head 15, the control valve 115 in the liquid inlet hole 112 is directly closed, the control valve 115 in the tap hole 114 is opened, and the external hydraulic pump is turned off. At this time, the residual hydraulic oil will flow along the tap hole 114 into the two pressure cylinders 261; After use, the high-pressure oil is returned through the return hole 113. At this time, the hydraulic rod 14 is lowered, and the extrusion rod 24 is driven to slide in the sealing cylinder 251 through the fixing frame 21. When sliding to the limit position, the extrusion rod 24 drives the sealing plate 257 and the first tooth plate 29 to move downward. Since the first tooth plate 29 descends slowly at this time, it is difficult to drive the rotating cylinder 283 to rotate at a high speed, resulting in the shift block 286 being unable to slide out smoothly. At the same time, because the extrusion rod 24 descends slowly, it can push the non-Newtonian fluid into the connecting cylinder 253. When an unexpected situation occurs, causing the hydraulic rod 14 to lose the support of the high-pressure oil in the hydraulic cylinder 12, the hydraulic rod 14 will fall rapidly. At this time, the hydraulic rod 14 quickly drives the extrusion rod 24 downward through the fixing frame 21. Since the extrusion rod 24 quickly squeezes the sealing gasket 256 and the non-Newtonian fluid in the connecting cylinder 253, it is difficult to squeeze the non-Newtonian fluid into the sealing cylinder 251. Therefore, the connecting cylinder 253 squeezes the sealing plate 257, causing it to push the first tooth plate 29 to fall rapidly in the slide groove 262. Since the first tooth plate 29 falls at a very fast speed, the tooth block 284 and the rotating drum 283 connected thereto will also rotate at a high speed. Under the action of the centrifugal force generated by the high-speed rotation, the shift block 286 is flipped out along the pin shaft 285. At this time, the rotating drum 283 drives the second tooth plate 271 to move upward through the shift block 286. The upward movement of the second tooth plate 271 drives the sealing partition 273 to separate from the drain pipe 264. Therefore, the high-pressure oil located below the pressure cylinder 261 can quickly pass through the isolation plate 263 and the drain pipe 264 and enter the top of the pressure cylinder 261, thereby pushing the sealing plate 257 to remain in place.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
