Description

Technical Field

[0001] This utility model relates to the field of material feeding devices, and more particularly to a hydraulic material feeding device for a generator unit. Background Technology

[0002] When producing metal tube and rod products, materials need to be transported by a conveying device, and the feed roller of the conveying mechanism, which is the conveying device, can usually be driven by a cylinder to rotate.

[0003] However, the air compressor of the cylinder needs to work continuously to maintain pressure, and the power of the air compressor needs to be increased during peak hours. The overall conversion efficiency of the pneumatic system from electrical energy to cylinder kinetic energy is only about 20%. At the same time, the pneumatic system also has leakage losses (about 30% of the compressed air does not do work), resulting in huge energy consumption.

[0004] Therefore, when the feed roller of the conveying device is driven by a cylinder to rotate, the air compressor of the cylinder needs to work continuously to maintain pressure, and the conversion efficiency of electrical energy to cylinder kinetic energy is low. At the same time, the pneumatic system also has the problem of air leakage, resulting in power waste. A hydraulic feed device can be designed for the unit to solve the above problems. Utility Model Content

[0005] To overcome the problems that arise when using a cylinder to drive the feed rollers of a conveyor to transport metal tubes and rods, such as the need for the air compressor to continuously operate to maintain pressure, low efficiency in converting electrical energy into cylinder kinetic energy, and air leakage in the pneumatic system, which would result in wasted electricity.

[0006] The technical solution of this utility model is as follows: a hydraulic feeding device for a generator unit, including multiple modular supports; it also includes turbine blades. A U-shaped groove is opened inside the modular support, and a drive shaft is rotatably connected inside the U-shaped groove. A turbine blade is fixedly connected in the middle of the drive shaft. Shaft seals fixedly connected to the modular support are provided on both sides of the outer side of the U-shaped groove. A feeding roller is fixedly connected to one side of the drive shaft. An oil inlet pipe is connected to one side of the lower end of the U-shaped groove, and a return pipe is connected to the other side of the lower end of the U-shaped groove. A hydraulic synchronization valve is installed on one side of the oil inlet pipe, and the front end of the hydraulic synchronization valve is connected to a hydraulic station through an oil pipe.

[0007] Preferably, the hydraulic station sends hydraulic oil into the hydraulic synchronization valve, which then evenly sends the hydraulic oil into multiple inlet pipes. As the hydraulic oil flows within the U-shaped groove, it drives the turbine blades and drive shaft to rotate the feed roller, thereby transferring the material placed on the upper end of the feed roller. The hydraulic oil passing through the turbine blades converges through the return pipe and flows back into the hydraulic station. The curved surface of the turbine blades can significantly reduce the energy loss of the hydraulic oil during the rotation of the turbine blades. The modular splicing method of the modular brackets can also conveniently adjust the overall length of the conveying device. Simply connect multiple modular brackets and assemble them together with bolts or other methods, and then connect all the U-shaped grooves to the inlet pipes and return pipes.

[0008] Preferably, the drive shaft and shaft seal are rotatably connected, and the hydraulic station and return pipe are fixedly connected.

[0009] Preferably, a first hexagonal bar is fixed to the other side of the drive shaft, a second hexagonal bar is fixed to one side of the feed roller, a ratchet is slidably connected to the second hexagonal bar, and a first sprocket is slidably connected to the first hexagonal bar.

[0010] Preferably, a second sprocket is provided on one side of the ratchet and slidably connected to the second hexagonal bar, a threaded clamp is provided on one side of the first sprocket and threaded clamp is provided on one side of the second sprocket and threaded clamp is also provided on one side of the second sprocket and threaded clamp is also provided on the second hexagonal bar.

[0011] Preferably, chains are mounted on both the first and second sprockets, and each chain is connected to two first sprockets or two second sprockets, with a pawl at the lower end of the ratchet.

[0012] Preferably, a spring guide rod is fixedly connected to the lower end of the pawl, and a fixing block is slidably connected to the lower end of the spring guide rod, and the fixing block is fixedly connected to the modular bracket.

[0013] Preferably, a limiting plate is provided at the lower end of the fixing block, and the limiting plate is fixedly connected to the lower end of the spring guide rod by bolts.

[0014] The beneficial effects of this utility model are:

[0015] By configuring turbine blades and a hydraulic synchronization valve, hydraulic oil can be fed into the hydraulic synchronization valve via a hydraulic station. The hydraulic synchronization valve then evenly distributes the hydraulic oil into multiple inlet pipes. As the hydraulic oil flows within the U-shaped groove, it drives the turbine blades and drive shaft, causing the feed roller to rotate. This rotation of the feed roller transfers the material placed on its upper end. The hydraulic oil passing through the turbine blades converges through the return pipe and flows back into the hydraulic station. Furthermore, the curved surface of the turbine blades significantly reduces energy loss during the rotation of the turbine blades. The modular splicing method of the modular support also allows for convenient adjustment of the entire conveying device. To achieve the desired body length, multiple modular brackets are simply connected and assembled together using bolts or other methods. Then, all the U-shaped grooves are connected to the oil inlet and return pipes. This allows the hydraulic system to replace the pneumatic system in driving the feed roller. The hydraulic pump can work intermittently, unlike the air compressor with a cylinder, which needs to work continuously to maintain pressure. It can be started only when power is needed. At the same time, the hydraulic station has a constant power, requiring no additional capacity. Furthermore, the hydraulic system can directly transfer kinetic energy to the drive shaft and feed roller through the turbine blades, without the need for transmission through gears, eccentric wheels, transmission rods, or other devices. This significantly improves energy conversion efficiency while saving electricity. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a hydraulic feeding device for a generator unit, comprising multiple modular supports 1 and turbine blades 4. A U-shaped groove 2 is formed inside the modular support 1, and a drive shaft 3 is rotatably connected inside the U-shaped groove 2. A turbine blade 4 is fixedly connected to the middle of the drive shaft 3. Shaft seals 5, fixedly connected to the modular support 1, are provided on both sides of the outer side of the U-shaped groove 2. A feeding roller 6 is fixedly connected to one side of the drive shaft 3. An oil inlet pipe 7 is connected to one side of the lower end of the U-shaped groove 2, and a return pipe 10 is connected to the other side of the lower end of the U-shaped groove 2. A hydraulic synchronization valve 8 is installed on one side of the oil inlet pipe 7. The front end of the hydraulic synchronization valve 8 is connected to a hydraulic station 9 via an oil pipe. The hydraulic station 9 sends hydraulic oil into the hydraulic synchronization valve 8, and the hydraulic synchronization valve 8 then... Hydraulic oil is evenly fed into multiple inlet pipes 7. Then, as the hydraulic oil flows in the U-shaped groove 2, it drives the turbine blades 4 and the drive shaft 3 to rotate the feed roller 6. The material placed on the upper end of the feed roller 6 is transferred by the rotation of the feed roller 6. The hydraulic oil passing through the turbine blades 4 is collected through the return pipe 10 and flows back into the hydraulic station 9. The arc-shaped curved blades of the turbine blades 4 can significantly reduce the energy loss of the hydraulic oil in the process of driving the turbine blades 4 to rotate. The modular splicing method of the modular brackets 1 can also conveniently adjust the overall length of the conveying device. Just connect multiple modular brackets 1 and assemble and fix them together with bolts or other methods, and then connect all the U-shaped grooves 2 with the inlet pipes 7 and the return pipes 10.

[0024] Please see Figures 2-5 In this embodiment, the drive shaft 3 and the shaft seal 5 are rotatably connected, the hydraulic station 9 and the return pipe 10 are fixedly connected, the shaft seal 5 is used to prevent hydraulic oil from seeping out of the U-shaped groove 2, a first hexagonal bar 11 is fixedly connected to the other side of the drive shaft 3, a second hexagonal bar 12 is fixedly connected to one side of the feed roller 6, a ratchet 13 is slidably connected to the second hexagonal bar 12, and a first sprocket 14 is slidably connected to the first hexagonal bar 11. The first hexagonal bar 11 and the second hexagonal bar 12 are used to make the ratchet 13, the first sprocket 14, ... The second sprocket 15 rotates synchronously with the drive shaft 3 and the feed roller 6. A second sprocket 15 is provided on one side of the ratchet 13 and is slidably connected to the second hexagonal bar 12. A threaded clamp 16 is provided on one side of the first sprocket 14 and is threadedly engaged with the first hexagonal bar 11. A threaded clamp 16 is also provided on one side of the second sprocket 15 and is threadedly engaged with the second hexagonal bar 12. The threaded clamp 16 is used to prevent the ratchet 13, the first sprocket 14, and the second sprocket 15 from falling off the first hexagonal bar 11 and the second hexagonal bar 12.

[0025] Please see Figures 3-5In this embodiment, chains 17 are installed on both the first sprocket 14 and the second sprocket 15, and each chain 14 is connected to two first sprockets 14 or two second sprockets 14. A pawl 18 is provided at the lower end of the ratchet 13. The hydraulic synchronization valve 8 evenly feeds hydraulic oil into multiple oil inlet pipes 7, allowing all the feed rollers 6 to rotate at the same speed. The first sprocket 14, the second sprocket 15, and the chain 17 work together as a guarantee mechanism, allowing the front and rear feed rollers 6 to limit each other's speed to a certain extent. A spring guide rod 19 is fixedly connected to the lower end of the pawl 18, and a fixing block 20 is slidably connected to the lower end of the spring guide rod 19. The fixing block 20 is fixedly connected to the modular bracket 1. The hydraulic station 9 is paused. During operation, the pawl 18 and the ratchet 13 engage with each other to prevent the feed roller 6 and the ratchet 13 from rotating in the opposite direction. When the feed roller 6 rotates in the forward direction, the pawl 18 can move up and down because the spring guide rod 19 allows it to move up and down. Therefore, the pawl 18 does not prevent the feed roller 6 and the ratchet 13 from rotating in the forward direction. The lower end of the fixed block 20 is provided with a limit plate 21, and the limit plate 21 is fixed to the lower end of the spring guide rod 19 by bolts. When it is necessary to replace the ratchet 13 and the pawl 18, the second sprocket 15 and the ratchet 13 can be removed after unscrewing the threaded clamp 16. Then, the bolts at the lower end of the limit plate 21 are unscrewed to separate the limit plate 21 from the lower end of the spring guide rod 19, and the pawl 18 and the spring guide rod 19 can be taken out from the fixed block 20.

[0026] In use, the hydraulic station 9 sends hydraulic oil into the hydraulic synchronization valve 8, which then evenly sends the hydraulic oil into multiple oil inlet pipes 7. As the hydraulic oil flows in the U-shaped groove 2, it drives the turbine blades 4 and the drive shaft 3 to rotate the feed roller 6. The material placed on the upper end of the feed roller 6 is transferred by the rotation of the feed roller 6. The hydraulic oil passing through the turbine blades 4 is collected through the return pipe 10 and flows back into the hydraulic station 9. The curved blades of the turbine blades 4 can significantly reduce the energy loss of the hydraulic oil in the process of driving the turbine blades 4 to rotate. The modular splicing method of the modular bracket 1 can also conveniently adjust the overall length of the conveying device. Just connect multiple modular brackets 1 and assemble and fix them together with bolts or other means, and then connect all the U-shaped grooves 2 with the oil inlet pipes 7 and the return pipes 10.

[0027] Meanwhile, the threaded clamp 16 is used to prevent the ratchet 13, the first sprocket 14, and the second sprocket 15 from falling off the first hexagonal bar 11 and the second hexagonal bar 12. The first hexagonal bar 11 and the second hexagonal bar 12 are used to make the ratchet 13, the first sprocket 14, and the second sprocket 15 rotate synchronously with the drive shaft 3 and the feed roller 6. The hydraulic synchronization valve 8 evenly sends hydraulic oil into multiple oil inlet pipes 7 so that all the feed rollers 6 can rotate at the same speed. The first sprocket 14, the second sprocket 15, and the chain 17 work together as a guarantee mechanism to limit the rotation speed of the front and rear feed rollers 6 to a certain extent.

[0028] Secondly, when the hydraulic station 9 is not in operation, the pawl 18 and the ratchet 13 engage with each other to prevent the feed roller 6 and the ratchet 13 from rotating in the opposite direction. When the feed roller 6 rotates in the forward direction, the pawl 18 can move up and down because the spring guide rod 19 allows it to move up and down. Therefore, the pawl 18 will not prevent the feed roller 6 and the ratchet 13 from rotating in the forward direction. When it is necessary to replace the ratchet 13 and the pawl 18, the second sprocket 15 and the ratchet 13 can be removed after unscrewing the threaded clamp 16. Then, the bolt at the lower end of the limit plate 21 is unscrewed to separate the limit plate 21 from the lower end of the spring guide rod 19, and the pawl 18 and the spring guide rod 19 can be removed from the fixing block 20.

[0029] Through the above steps, by setting the turbine blades 4 and the hydraulic synchronization valve 8, hydraulic oil can be sent to the hydraulic synchronization valve 8 through the hydraulic station 9. The hydraulic synchronization valve 8 then evenly sends the hydraulic oil into multiple oil inlet pipes 7. Then, as the hydraulic oil flows in the U-shaped groove 2, it drives the turbine blades 4 and the drive shaft 3 to rotate the feed roller 6, so that the material placed on the upper end of the feed roller 6 is transferred through the rotation of the feed roller 6. The hydraulic oil passing through the turbine blades 4 is collected through the return pipe 10 and flows back into the hydraulic station 9. Moreover, the arc-shaped curved blades of the turbine blades 4 can significantly reduce the energy loss of the hydraulic oil in the process of driving the turbine blades 4 to rotate. The modular splicing method of the modular bracket 1 can also facilitate the modular assembly of the material. Adjusting the overall length of the conveying device simply requires connecting multiple modular supports 1 together and assembling them with bolts or other methods. Then, all the U-shaped grooves 2 are connected to the oil inlet pipe 7 and the return pipe 10. This allows the hydraulic system to drive the feed roller 6 to rotate instead of the pneumatic system. The hydraulic pump can work intermittently, unlike the air compressor with a cylinder, which needs to work continuously to maintain pressure. It can be started only when power is needed. At the same time, the hydraulic station 9 has a constant power and does not require additional capacity. Furthermore, the hydraulic power can directly transfer kinetic energy to the drive shaft 3 and the feed roller 6 through the turbine blades 4, without the need for transmission through gears, eccentric wheels, transmission rods, or other devices. This saves electricity and significantly improves energy conversion efficiency.
