Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a pretreatment cleaning device for cast steel gear parts of a hydraulic reducer. Background Technology

[0002] As a crucial transmission device in water conservancy projects, the core component of hydraulic reducers, gears, is mostly made of cast steel through a casting process. During the casting process of gear cast steel parts, impurities such as casting sand easily adhere to their surfaces and in the gaps of tooth grooves and roots. If these impurities are not thoroughly removed in subsequent processing (such as cutting and grinding) or before assembly, they will seriously affect the gear machining accuracy, leading to increased transmission noise, accelerated wear, and even shortening the overall service life of the hydraulic reducer. Therefore, pre-treatment cleaning of gear cast steel parts is a key process to ensure equipment performance.

[0003] Currently, the pretreatment and cleaning of cast steel gear parts for hydraulic reducers in the industry mostly involves manual brushing with cleaning solution. This method requires workers to directly contact the cleaning agent, which poses certain safety hazards. Furthermore, manual operation makes it difficult to cover all gaps in the gears, easily creating cleaning dead spots. At the same time, the cleaning efficiency is extremely low, making it difficult to meet the needs of mass production.

[0004] Therefore, there is an urgent need for a specialized cleaning device that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a reasonably designed pretreatment and cleaning device for cast steel gear parts of hydraulic reducers, which can solve the above-mentioned defects and deficiencies of the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a liquid storage tank, a drain valve pipe is provided at the bottom of the liquid storage tank, a clamping and rotating assembly is provided inside the liquid storage tank, a tensioning element is provided on the clamping and rotating assembly, and a cleaning assembly is provided inside the liquid storage tank.

[0007] Preferably, the liquid storage tank is provided with a filter plate inside, and a detachable filter cloth is provided on the top of the filter plate. The liquid storage tank has symmetrical movable openings on the front and rear sides, and a sliding groove is provided on the inner bottom surface of each movable opening. Sliding sleeves are symmetrically provided on the left and right side walls of the liquid storage tank, and an installation plate is provided on the front outer wall of the liquid storage tank.

[0008] Preferably, the clamping and rotating assembly includes a pair of telescopic cylinders, which are symmetrically arranged on the left and right outer walls of the liquid storage tank. The telescopic cylinders are movably arranged in the sliding sleeve. A push plate is fixed at the top of the telescopic rod of each telescopic cylinder. Both sides of the push plate are arranged in the movable opening. A pair of fixed plates are provided on the push plate. A rotating shaft is movably arranged between each pair of fixed plates through a pair of bearing seats. A clamping plate is provided at the adjacent end of the two rotating shafts. An anti-slip pad is provided on the front of the clamping plate. One of the push plates has a support block at one end outside the movable opening. A motor is mounted on the support block, and a second sprocket is mounted on the drive end of the motor. A first sprocket is mounted on the shaft of the same push plate. The first and second sprockets are connected by a chain drive. The push plate has a mounting groove, and the tensioning member is mounted in the mounting groove.

[0009] Preferably, the tensioning component includes a telescopic cylinder two disposed at the bottom of the push plate. The telescopic cylinder two is located below the mounting groove, and the telescopic rod of the telescopic cylinder two passes through the push plate and is located in the mounting groove. A U-shaped frame is provided at the top of the telescopic rod of the telescopic cylinder two, and a sprocket three is movably disposed in the U-shaped frame. The sprocket three is connected to the chain drive.

[0010] Preferably, the cleaning assembly includes a water pump mounted on a mounting plate. The input end of the water pump is provided with a first delivery pipe, the end of the first delivery pipe away from the water pump is located inside a storage tank and below the filter plate. The output end of the water pump is provided with a second delivery pipe, the end of the second delivery pipe away from the water pump is located above the filter plate, and its port is provided with a U-shaped water passage component. Several nozzles are provided on both sides of the inner wall and the inner bottom surface of the U-shaped water passage component, and several rows of bristles are provided between adjacent nozzles.

[0011] Preferably, a slider is provided at the bottom of the push plate corresponding to the position of the slide groove, and the slider is movably disposed in the slide groove.

[0012] The beneficial effects of this utility model after adopting the above structure are: 1. This utility model combines rotation, brushing, and rinsing. The gear rotates under the drive of the motor, allowing all parts, such as the tooth surface and tooth root, to evenly contact the bristles and nozzles inside the U-shaped water-passing component. High-pressure cleaning fluid is sprayed from multiple directions, which, together with the friction and peeling of stubborn casting sand by the bristles, can significantly shorten the cleaning time compared to traditional manual cleaning or single rinsing. At the same time, it avoids cleaning dead corners and ensures that impurities on the surface and in the gaps of the gear are thoroughly removed, providing a workpiece foundation with higher cleanliness for subsequent processing or assembly.

[0013] 2. This utility model, through the design of filter plate and detachable filter cloth, can filter solid impurities such as casting sand and metal shavings in the cleaning mixture, so that the filtered cleaning liquid falls back to the bottom of the storage tank for recycling. This design greatly reduces the amount of cleaning liquid consumed per use, reducing the cost of cleaning agent procurement for enterprises; at the same time, the detachable filter cloth makes it easy to clean impurities regularly, eliminating the need for frequent replacement of filter components, further reducing the cost of consumable replacement and maintenance time.

[0014] 3. By setting up a tensioning component, when the chain becomes loose due to long-term use, the telescopic cylinder two can be controlled to push out the telescopic rod, which quickly drives the sprocket three to move upward to tighten the chain. The tension adjustment can be completed without disassembling the transmission components, making the operation convenient and efficient. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-7 As shown, this utility model proposes a pretreatment and cleaning device for cast steel gears of a hydraulic reducer. It includes a liquid storage tank 1, which is the main supporting structure of the device. A drain valve pipe is welded and fixed to the bottom of the tank for discharging waste cleaning liquid. A filter plate 10 is horizontally mounted inside the liquid storage tank 1. A filter cloth 11 is detachably fixed to the top of the filter plate 10 to achieve solid-liquid separation. Long strip-shaped movable openings 12 are symmetrically opened on the front and rear side walls of the liquid storage tank 1. Each movable opening 12 has a sliding groove 13 on its inner bottom surface. Sliding sleeves 15 are symmetrically welded and fixed on the left and right side walls. An installation plate 14 is fixed to the front outer wall to provide an installation base for subsequent components. A pair of telescopic cylinders 20 for clamping the rotating assembly 2 are symmetrically fixed on the outer walls of the left and right sides of the liquid storage tank 1. The telescopic rods of the telescopic cylinders 20 move through the sliding sleeve 15 and extend into the liquid storage tank 1. A push plate 21 is welded and fixed to the top of each telescopic rod. A slider 22 is integrally formed at the bottom of the push plate 21 corresponding to the position of the sliding groove 13. The slider 22 slides with the sliding groove 13. At the same time, the two sides of the push plate 21 are located in the movable opening 12 to realize the stable movement of the push plate 21. A pair of fixing plates 23 are welded and fixed to the top of the push plate 21. A bearing seat 24 is fixed between each pair of fixing plates 23 by bolts. The rotating shaft 25 is rotatably set in the bearing seat 24 through the bearing. A clamping plate 26 is welded to the adjacent end of the two rotating shafts 25. An anti-slip pad 27 is pasted on the front of the clamping plate 26 to enhance the clamping stability. One of the push plates 21 has a support block 213 welded to one end outside the movable opening 12. A motor 210 is fixed on the support block 213, and the transmission end of the motor 210 is connected to a second sprocket 29. A first sprocket 28 is connected to the rotating shaft 25 on the same push plate 21. The first sprocket 28 and the second sprocket 29 are connected by a chain 212. The push plate 21 has a mounting groove 211 for installing the tensioning member 3. The telescopic cylinder 30 of the tensioning component 3 is fixed at the bottom of the push plate 21 and located directly below the mounting groove 211. Its telescopic rod passes through the push plate 21 and extends into the mounting groove 211. A U-shaped frame 31 is welded and fixed to the top of the telescopic rod. A sprocket 32 ​​is movably arranged in the U-shaped frame 31 through a pin shaft. The sprocket 32 ​​meshes with the chain 212 to form the chain 212 tensioning structure. The water pump 40 of the cleaning component 4 is fixed to the mounting plate 14 by bolts. The input end of the water pump 40 is connected to the first pipe 41. The end of the first pipe 41 away from the water pump 40 extends into the liquid storage tank 1 and is located below the filter plate 10. The output end of the water pump 40 is connected to the second pipe 42. The end of the second pipe 42 away from the water pump 40 extends above the filter plate 10, and the port is connected to a U-shaped water passage 45. Several nozzles 43 are threadedly connected to the inner walls and bottom surface of the two sides of the U-shaped water passage 45. Several rows of bristles 44 are fixed between adjacent nozzles 43 by bolts, forming a structure that combines brushing and rinsing.

[0019] When pre-treating and cleaning the cast steel gear, the gear to be cleaned is first placed between two clamping plates 26, and the gear is ensured to be within the encirclement of the U-shaped water passage 45. Then, the controller triggers two telescopic cylinders 20 to push out the telescopic rods at the same time, driving the push plate 21 to move inward along the slide groove 13 until the clamping plates 26 on both sides are tightly attached to the end face of the gear. The friction of the anti-slip pad 27 is used to achieve a stable clamping and fixing of the gear. After clamping is completed, the motor 210 and water pump 40 are started by the controller. When the motor 210 is running, its transmission end drives the second sprocket 29 to rotate. The second sprocket 29 drives the first sprocket 28 to rotate synchronously through the chain 212, which in turn drives the rotating shaft 25 connected to it to rotate. Under the linkage of the gears, the rotating shaft 25 on the other side rotates synchronously with the gears, realizing the uniform rotation of the gears. After the water pump 40 is started, the cleaning liquid under the filter plate 10 in the storage tank 1 is drawn out through the first pipe 41, and then pressurized and transported to the U-shaped water passage 45 through the second pipe 42. Finally, it forms a high-pressure water jet through the nozzles 43 in all directions and sprays it onto the surface of the gear. During the rotation of the gear, its tooth surface, tooth root and other parts continuously contact and rub against the bristles 44 in the U-shaped water passage 45. Combined with the flushing action of the high-pressure cleaning fluid, the casting sand, metal shavings and other impurities attached to the gear surface and gaps are effectively removed. The cleaning mixture flows downward under the action of gravity and is filtered by the filter cloth 11 to intercept solid impurities such as casting sand. The filtered cleaning fluid falls back to the bottom of the storage tank 1 through the filter plate 10, realizing the recycling of the cleaning fluid and reducing the cost of consumables. When the chain 212 becomes loose due to long-term use of the device, affecting the transmission efficiency, the controller controls the telescopic cylinder 2 30 to push out the telescopic rod, driving the U-shaped frame 31 and the sprocket 3 32 to move upward. The sprocket 3 32 supports the chain 212 to tighten it again, ensuring the stable operation of the transmission structure. After the cleaning operation is completed, the motor 210 and water pump 40 are turned off, and the telescopic cylinder 20 is controlled to retract the telescopic rod to release the clamp, so that the cleaned gear can be taken out. The filter cloth 11 can be removed periodically to clean the trapped impurities, and the aged cleaning solution can be discharged through the drain valve pipe for replacement.
