Description

Technical Field

[0001] This invention relates to a gearbox cleaning device, belonging to the field of gearbox cleaning technology. Background Technology

[0002] To clean a gearbox, it is often necessary to use water and detergent to rinse the inside and outside of the gearbox to remove stains.

[0003] Typically, cleaning a gearbox requires placing it on a flat surface and rinsing it multiple times with a spray nozzle. This leaves some water residue inside the gearbox, which can accelerate corrosion of the inner walls if the gearbox is not dried promptly, thus posing a problem. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a gearbox cleaning device that solves the problem in the prior art where water accumulates inside the gearbox after rinsing the gearbox with a rinsing nozzle, accelerating the corrosion of the gearbox's inner wall.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: a gearbox cleaning device, comprising: The outer casing is cleaned, and a cleaning chamber is provided inside. The auxiliary water pipe is fixed at an angle to the inner wall of the cleaning chamber. The support rod is coaxially mounted with the auxiliary water pipe and is positioned inside the cleaning chamber on the side opposite to the auxiliary water pipe. The extended nozzle is fixedly mounted at the end of the auxiliary water pipe facing the support rod. The adsorption structure is located at the end of the support rod facing the auxiliary water pipe. The adsorption structure and the extended nozzle together abut and clamp the opposite surface of the gearbox. The top support frame is installed on top of the support rod and auxiliary water pipe. The main nozzle is fixedly mounted on the side of the top support frame facing the cleaning chamber. Several main nozzles are provided. The water inlet pipe is fixedly installed on the outer casing of the cleaning unit and connected to the main nozzle through a pipeline.

[0006] By adopting the above technical solution, the gearbox is placed between the extended nozzle and the adsorption structure, so that the gearbox is always in an inclined state. The water inlet pipe is connected to the external water supply equipment. At this time, after the main nozzle sprays water, the water flow washes the surface of the gearbox, achieving the effect of cleaning the gearbox. At the same time, the gearbox is in an inclined state, which makes it difficult for water to accumulate in the gearbox. During the static time after rinsing, the water can be discharged under the action of gravity, avoiding excessive water accumulation and helping to reduce the corrosion rate of the gearbox surface.

[0007] The present invention is further configured such that the adsorption structure includes: The adjusting cylinder is sleeved on the support rod and threadedly connected to the support rod. The rotating sleeve is rotatably mounted on the outside of the adjusting cylinder. The suction cup is fixed to the end of the rotating sleeve facing the auxiliary water pipe.

[0008] By adopting the above technical solution, when the gearbox is clamped between the adsorption structure and the extended nozzle, by rotating the adjusting cylinder, the adjusting cylinder moves towards the auxiliary water pipe under the action of the threaded structure, and at the same time drives the suction cup to move towards the surface of the gearbox. Finally, the suction cup comes into contact with the surface of the gearbox and is pressed to undergo elastic deformation. At this time, because the gas between the suction cup and the surface of the gearbox is squeezed out, the suction cup is adsorbed on the surface of the gearbox under atmospheric pressure. When the extended nozzle and the adjusting cylinder come into contact with the gearbox at the same time, the adsorption of the suction cup can improve the stability of the gearbox during clamping and cleaning.

[0009] The invention is further configured such that: the extended nozzle is hollow to form a water guiding cavity, the water guiding cavity is connected to the interior of the auxiliary water pipe, and a plurality of water spray holes are opened at the end of the extended nozzle away from the auxiliary water pipe, and the auxiliary water pipe is connected to the water inlet pipe.

[0010] By adopting the above technical solution, the water flow from the inlet pipe can also be guided into the auxiliary water pipe and then into the extension nozzle, where it is sprayed out through the spray hole. When the extension nozzle is located inside the gearbox, the water flow sprayed out by the extension nozzle can directly rinse the side wall inside the gearbox. Due to the tilted state of the gearbox, the rinsed water is discharged from inside the gearbox in a timely manner and will not accumulate inside the gearbox, thus ensuring the cleanliness of the gearbox's inner wall and reducing the risk of gearbox corrosion.

[0011] The invention is further configured such that: a baffle plate is slidably disposed within the water guiding cavity along the axial direction of the auxiliary water pipe, the baffle plate abuts and seals against the inner wall of the water guiding cavity, and the baffle plate can abut and seal the water spray hole; a connecting rod extending into the auxiliary water pipe is fixedly disposed at one end of the baffle plate facing the auxiliary water pipe; a permeable plate is fixedly disposed at the end of the connecting rod located in the auxiliary water pipe; a sliding groove is radially provided on the auxiliary water pipe; a switching sleeve is sleeved on the outside of the auxiliary water pipe; the permeable plate passes through the sliding groove and is fixed to the switching sleeve; and the connection between the switching sleeve and the auxiliary water pipe is sealed.

[0012] The invention is further configured such that: a rotating ring is rotatably provided on the side of the switching sleeve away from the extension nozzle, and the rotating ring is threadedly connected to the auxiliary water pipe.

[0013] By adopting the above technical solution, rotating the rotating ring can drive the switching sleeve to move axially along the auxiliary water pipe under the action of the threaded structure. This causes the switching sleeve to move the permeable plate, which in turn causes the permeable plate to move the baffle plate in the water guiding cavity through the connecting rod. This adjusts the number of water spray holes on the side of the baffle plate facing the auxiliary water pipe, thereby controlling the number and position of water sprayed from the water spray holes. This allows the water spray holes to select the number and position of water sprayed according to actual needs, satisfying the versatility of cleaning the inner wall of the gearbox.

[0014] The invention is further configured such that: the permeable plate abuts and seals against the inner wall of the auxiliary water pipe, and a plurality of permeable holes are opened through the permeable plate; a sealing block aligned with the permeable holes is fixedly installed on the side of the auxiliary water pipe facing the extended spray pipe, and the sealing block can be inserted into the permeable hole and close the permeable hole.

[0015] By adopting the above technical solution, the permeable plate moves along with the water flow and the sealing block is inserted into the permeable hole. At this time, the sealing block and the permeable plate together seal the inside of the auxiliary water pipe, preventing water from spraying out through the spray hole, thus achieving the purpose of temporarily restricting the water flow. This allows the cleaning device to temporarily stop spraying water in an emergency, improving the reliability of the cleaning device.

[0016] The invention is further configured such that: an auxiliary water spraying plate is fixedly installed at the connection end of the extended nozzle and the auxiliary water pipe; a plurality of auxiliary nozzles are fixedly installed on the side of the auxiliary water spraying plate facing the support rod; the auxiliary water spraying plate is hollow to form an auxiliary water storage cavity; the auxiliary water storage cavity is connected to the auxiliary nozzles; a connecting pipe is installed on the side of the sealing block away from the permeable plate; one end of the connecting pipe extends into the auxiliary water storage cavity; the other end of the connecting pipe passes through the sealing block and extends to the side of the sealing block facing the permeable plate; a pressure valve is fixedly installed on the part of the connecting pipe that passes through the sealing block.

[0017] By adopting the above technical solution, when the sealing block is inserted into the permeable hole, the auxiliary water pipe is sealed by the permeable plate and the sealing block. As water continues to flow into the inlet pipe, the water pressure on the side of the permeable plate away from the sealing block increases and reaches the opening threshold of the pressure valve. At this time, the water flow will not be sprayed out through the spray hole due to the sealing effect of the permeable plate and the sealing block. The water flow is introduced into the auxiliary water storage chamber through the connecting pipe and sprayed out through the auxiliary nozzle. At this time, the water flow sprayed by the auxiliary nozzle is directly sprayed onto the bottom wall inside the gearbox, so that the cleaning device can independently clean the bottom wall inside the gearbox, improving the versatility of the cleaning device.

[0018] The beneficial effects of this invention are: by placing the gearbox between the extended nozzle and the adsorption structure, the gearbox is always in an inclined state. The water inlet pipe is connected to an external water supply device. When the main nozzle sprays water, the water flow washes the surface of the gearbox, achieving the effect of cleaning the gearbox. At the same time, the gearbox is in an inclined state, which makes it difficult for water to accumulate in the gearbox, thus avoiding excessive water accumulation and helping to reduce the rust rate on the surface of the gearbox.

[0021] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0022] like Figure 1-2As shown, a gearbox cleaning device includes a cleaning outer housing 10, a top support frame 11, a water inlet pipe 13, a support rod 14, a main nozzle 18, an auxiliary water pipe 19, an extension nozzle 23, and an adsorption structure. The cleaning outer housing 10 contains a cleaning chamber 12, which is horizontally arranged on both opposite sides and connected to an external drainage pipe. The auxiliary water pipe 19 is obliquely fixed to the inner wall of the cleaning chamber 12. The support rod 14 is coaxially arranged with the auxiliary water pipe 19 and is located on the side of the cleaning chamber 12 opposite to the auxiliary water pipe 19. The extension nozzle 23 is fixedly located at the end of the auxiliary water pipe 19 facing the support rod 14, and an anti-slip layer is fixedly provided at the end of the extension nozzle 23 facing the support rod 14. The adsorption structure is located at the end of the support rod 14 facing the auxiliary water pipe 19. The adsorption structure and the extension nozzle 23 together abut and clamp against the opposite surfaces of the gearbox. When the extension nozzle 23 and the adsorption structure clamp the gearbox together, the extension nozzle 23 must be located inside the gearbox. The top support frame 11 is set on top of the support rod 14 and the auxiliary water pipe 19. The top support frame 11 is set in a horizontal direction. The main nozzle 18 is fixedly set on the side of the top support frame 11 facing the cleaning chamber 12. There are several main nozzles 18. One end of the water inlet pipe 13 is fixedly set on the cleaning outer casing 10 and connected to the main nozzle 18 through the pipeline. The other end of the water inlet pipe 13 is connected to the external water supply equipment.

[0023] like Figure 1-2 As shown, the adsorption structure includes an adjusting cylinder 15, a rotating sleeve 16, and a suction cup 17. The adjusting cylinder 15 is sleeved on the support rod 14 and threadedly connected to the support rod 14. An anti-slip layer is fixed at the end of the adjusting cylinder 15 away from the support rod 14. The protective layers on the extension nozzle 23 and the adjusting cylinder 15 include a rubber layer, a burlap layer, etc. The rotating sleeve 16 is rotatably positioned outside the adjusting cylinder 15, and the suction cup 17 is fixed at the end of the rotating sleeve 16 facing the auxiliary water pipe 19. The suction cup 17 is made of flexible rubber.

[0024] like Figure 2-3As shown, the extended nozzle 23 is hollow to form a water guiding cavity 25, which is connected to the interior of the auxiliary water pipe 19. Several water spray holes 24 are opened at the end of the extended nozzle 23 away from the auxiliary water pipe 19. The auxiliary water pipe 19 is connected to the water inlet pipe 13. A baffle plate 35 is slidably disposed within the water guiding cavity 25 along the axial direction of the auxiliary water pipe 19. The baffle plate 35 abuts and seals against the inner wall of the water guiding cavity 25, and can also abut and seal the spray hole 24, thereby reducing the amount of water discharged from the spray hole 24. A connecting rod 31 extending into the auxiliary water pipe 19 is fixedly disposed at the end of the baffle plate 35 facing the auxiliary water pipe 19. A permeable plate 29 is fixedly disposed at the end of the connecting rod 31 located in the auxiliary water pipe 19. A sliding groove 28 is radially provided through the auxiliary water pipe 19. A switching sleeve 26 is sleeved on the outside of the auxiliary water pipe 19. The permeable plate 29 partially passes through the sliding groove 28 and is fixed to the switching sleeve 26. The connection between the switching sleeve 26 and the auxiliary water pipe 19 is sealed. A rotating ring 27 is rotatably disposed on the side of the switching sleeve 26 away from the extended nozzle 23, and is sleeved on the auxiliary water pipe 19. The rotating ring 27 is threadedly connected to the auxiliary water pipe 19.

[0025] like Figure 2-3 As shown, the permeable plate 29 is sealed against the inner wall of the auxiliary water pipe 19. Several permeable holes 30 are opened through the permeable plate 29. A sealing block 32 aligned with the permeable holes 30 is fixedly installed on the side of the auxiliary water pipe 19 facing the extension nozzle 23. The sealing block 32 can be inserted into the permeable hole 30 and close the permeable hole 30. An auxiliary water spray plate 20 is fixedly installed at the connection end of the extension nozzle 23 and the auxiliary water pipe 19. Several auxiliary nozzles 21 are fixedly installed on the side of the auxiliary water spray plate 20 facing the support rod 14. The auxiliary water spray plate 20 is hollow to form an auxiliary water storage cavity 22. The auxiliary water storage cavity 22 is connected to the auxiliary nozzles 21. A connecting pipe 33 is installed on the side of the sealing block 32 away from the permeable plate 29. One end of the connecting pipe 33 extends into the auxiliary water storage cavity 22, and the other end of the connecting pipe 33 passes through the sealing block 32 and extends to the side of the sealing block 32 facing the permeable plate 29. A pressure valve 34 is fixedly installed on the part of the connecting pipe 33 that passes through the sealing block 32.

[0026] By placing the gearbox between the extended nozzle 23 and the adsorption structure, the gearbox is always in an inclined state. The water inlet pipe 13 is connected to an external water supply device. When the main nozzle 18 sprays water, the water flow washes the surface of the gearbox, achieving the effect of cleaning the gearbox. At the same time, the gearbox is in an inclined state, which makes it difficult for water to accumulate in the gearbox, thus avoiding excessive water accumulation and helping to reduce the rust rate on the surface of the gearbox.

[0027] When the gearbox is clamped between the adsorption structure and the extension nozzle 23, by rotating the adjusting cylinder 15, the adjusting cylinder 15 moves toward the auxiliary water pipe 19 under the action of the threaded structure, and at the same time, it drives the suction cup 17 to move toward the surface of the gearbox. Finally, the suction cup 17 comes into contact with the surface of the gearbox and is pressed to undergo elastic deformation. At this time, because the gas between the suction cup 17 and the surface of the gearbox is squeezed out, the suction cup 17 is adsorbed onto the surface of the gearbox under atmospheric pressure. When the extension nozzle 23 and the adjusting cylinder 15 come into contact with the gearbox at the same time, the adsorption of the suction cup 17 can improve the stability of the gearbox during clamping and cleaning.

[0028] The water flow from the inlet pipe 13 can also be directed into the auxiliary water pipe 19 and into the extension nozzle 23, where it is sprayed out through the spray hole 24. When the extension nozzle 23 is located inside the gearbox, the water flow sprayed from the extension nozzle 23 can directly rinse the side wall inside the gearbox. Due to the tilt of the gearbox, the rinsed water is discharged from inside the gearbox in a timely manner and will not accumulate inside the gearbox, thus ensuring the cleanliness of the gearbox's inner wall and reducing the risk of gearbox corrosion.

[0029] Rotating the rotating ring 27 causes the switching sleeve 26 to move axially along the auxiliary water pipe 19 under the action of the threaded structure. This causes the switching sleeve 26 to move the permeable plate 29, which in turn causes the permeable plate 29 to move through the connecting rod 31 and the baffle plate 35 within the water guiding cavity 25. This adjusts the number of water spray holes 24 on the side of the baffle plate 35 facing the auxiliary water pipe 19, thereby controlling the number and position of water sprayed from the water spray holes 24. This allows the water spray holes 24 to select the number and position of water sprayed according to actual needs, satisfying the versatility of cleaning the inner wall of the gearbox.

[0030] As the permeable plate 29 moves, the sealing block 32 is inserted into the permeable hole 30. At this time, the sealing block 32 and the permeable plate 29 together seal the inside of the auxiliary water pipe 19, preventing water from spraying out through the spray hole 24. This achieves the purpose of temporarily restricting the water flow, enabling the cleaning device to temporarily stop spraying water in an emergency, thus improving the reliability of the cleaning device.

[0031] When the sealing block 32 is inserted into the permeable hole 30, the auxiliary water pipe 19 is sealed by the permeable plate 29 and the sealing block 32. As water continues to flow into the inlet pipe 13, the water pressure on the side of the permeable plate 29 away from the sealing block 32 increases and reaches the opening threshold of the pressure valve 34. At this time, the water will not be sprayed out through the spray hole 24 due to the sealing effect of the permeable plate 29 and the sealing block 32. The water is introduced into the auxiliary water storage chamber 22 through the connecting pipe 33 and sprayed out through the auxiliary nozzle 21. At this time, the water sprayed out by the auxiliary nozzle 21 is directly sprayed onto the bottom wall inside the gearbox, so that the cleaning device can independently clean the bottom wall inside the gearbox, improving the versatility of the cleaning device.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
