Description

Technical Field

[0001] This utility model belongs to the field of rail train technology, specifically relating to an ultrasonic cleaning device. Background Technology

[0002] Ultrasonic cleaning of railcar components is a crucial process for ensuring their stable performance. Existing cleaning equipment typically uses a fixed support plate inside the ultrasonic cleaning chamber. Components are placed in a placement box and then manually placed onto the support plate inside the chamber for cleaning. However, this technical solution has significant drawbacks:

[0003] Manual operation is physically demanding: To ensure that the cleaning fluid completely covers the parts, the support plate is usually set near the bottom of the cleaning tank. Workers need to frequently bend over, lean over or even squat to operate. When putting in or taking out the placement box, they need to overcome gravity. Each operation consumes a lot of physical strength, especially for heavy parts (such as bogie parts, brake valves, etc.), which can easily lead to occupational injuries such as lumbar muscle strain. Utility Model Content

[0004] In view of this, the present invention provides an ultrasonic cleaning device to solve the problem in the prior art that workers need to frequently bend over, lean forward, or even squat to put in or take out the placement box, which consumes a lot of physical strength in a single operation, especially for heavy parts (such as bogie parts, brake valves, etc.), which can easily lead to occupational injuries such as lumbar muscle strain.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An ultrasonic cleaning device includes an ultrasonic cleaning chamber. A support plate and a door are spaced apart at the top opening of the ultrasonic cleaning chamber. A hinge seat is provided on the top of the support plate, and a rotating shaft is rotatably connected to the hinge seat. A connecting plate is provided on the top of the door, and one end of the connecting plate away from the door is fixedly connected to the rotating shaft. Inside the ultrasonic cleaning chamber, a support plate is provided for supporting a parts placement box. A connecting rod is provided on one side of the support plate, and the top of the connecting rod slides out of the support plate and connects to a top plate. A lifting device for raising and lowering the top plate is provided on one side of the ultrasonic cleaning chamber.

[0007] In this technical solution, it should be noted that the ultrasonic cleaning device achieves convenient loading and unloading of the parts placement box through a liftable support plate and a linked door structure. Specifically, a support plate is located on one side of the top opening of the ultrasonic cleaning box, and a door is located on the other side. A hinged seat on the top of the support plate is rotatably connected to a rotating shaft. A connecting plate on the top of the door rigidly fixes the door to the rotating shaft, forming a rotating opening and closing structure with the rotating shaft as the fulcrum. Operators can open and close the cleaning box by rotating the door, and the door seals against the top of the cleaning box when closed to prevent liquid splashing. The support plate inside the cleaning box supports the parts placement box, with a connecting rod vertically fixed on one side. The top of the connecting rod passes through a sliding hole in the support plate and connects to the top plate, forming a rigid linkage structure between the support plate and the top plate. A lifting device on one side of the washing tank drives the top plate to rise and fall vertically, which in turn drives the connecting rod and the support plate to move synchronously. When it is necessary to place or remove the parts placement box, the lifting device drives the top plate to rise, raising the support plate to a higher position in the washing tank (close to the height of a person standing and operating). The staff can place the placement box containing the parts smoothly on the support plate or remove it from the support plate without bending over. After placement, the lifting device drives the top plate to fall, so that the support plate carrying the placement box is immersed in the cleaning solution. At this time, the door can be closed to start ultrasonic cleaning. This structure realizes convenient opening and closing of the washing tank through the door design with a rotating shaft linkage. The lifting device transforms the traditional fixed low-position support plate into an adjustable height movable support, solving the problem of labor intensity caused by manual bending over to load and unload.

[0008] Preferably, the lifting device includes a first hydraulic cylinder, which is located on one side of the ultrasonic cleaning chamber, is vertically arranged, and has a piston rod connected to the top plate.

[0009] In this technical solution, it should be noted that the lifting device uses a first hydraulic cylinder vertically installed on one side of the ultrasonic cleaning box. Its piston rod is rigidly connected to the top plate, and the lifting control of the top plate is achieved through hydraulic drive: the first hydraulic cylinder serves as a power source, using the pressure of hydraulic oil to push the piston rod to make linear motion, directly driving the top plate to rise and fall in the vertical direction, and then causing the support plate to move up and down synchronously through the connecting rod; because the hydraulic cylinder has the characteristics of large thrust and smooth operation, it can ensure that the support plate maintains a horizontal posture during the lifting process, and prevent the parts inside the box from slipping due to tilting.

[0010] Preferably, the ultrasonic cleaning box is also provided with a guide rail on one side, the guide rail is vertically arranged, and the top plate is slidably sleeved on the guide rail.

[0011] In this technical solution, it should be noted that a vertical guide rail is added to one side of the ultrasonic cleaning box, and the top plate is slidably fitted onto the guide rail, forming a rigid guiding structure for the lifting and lowering movement of the top plate. The guide rail is made of high-strength aluminum alloy or steel profile, and its length covers the entire lifting and lowering stroke of the support plate. The side of the top plate is equipped with a sliding sleeve or slider (such as a linear bearing or ball bearing slider) that cooperates with the guide rail, so that the top plate moves linearly along the axis of the guide rail (vertical direction) during the lifting and lowering process, effectively limiting lateral deviation. This design works in conjunction with the first hydraulic cylinder (or other lifting device). The hydraulic cylinder provides the lifting power, and the guide rail provides lateral constraint. The combination of the two eliminates the risk of top plate tilting caused by a long piston rod or load eccentricity, ensuring that the support plate always maintains a horizontal posture and avoiding damage to the parts inside the box due to shaking and collision.

[0012] Preferably, one side of the ultrasonic cleaning box is further provided with a support frame, the top of the support frame is hinged to a second hydraulic cylinder, a rotating plate is hinged to the piston rod of the second hydraulic cylinder, and the end of the rotating plate away from the second hydraulic cylinder is fixedly connected to a rotating shaft.

[0013] In this technical solution, it should be noted that a support frame is installed on one side of the ultrasonic cleaning chamber, with a second hydraulic cylinder hinged to its top. The piston rod is connected to a rotating plate via a hinge structure, and a rotating shaft is fixed at the other end of the rotating plate, forming an automated drive system for the chamber door. The support frame serves as the basic support component, providing a hinge fulcrum for the second hydraulic cylinder, thus forming a kinematic chain of "cylinder body fixed - piston rod extension and retraction - rotating plate rotation." When the piston rod of the second hydraulic cylinder retracts, it pushes the rotating plate to rotate, causing the fixed rotating shaft to rotate synchronously. This, in turn, causes the chamber door to rotate counterclockwise around the rotating shaft to open via a connecting plate. Conversely, when the piston rod extends, the rotating plate rotates downwards, and the chamber door rotates clockwise to close. This design converts the linear motion of the hydraulic cylinder into the rotational motion of the chamber door, achieving automatic opening and closing of the chamber door and avoiding manual operation. It is particularly suitable for heavy-duty cleaning chambers or high-frequency usage scenarios.

[0014] Preferably, a support column is provided on one side of the ultrasonic cleaning box, and the top of the support column contacts the bottom of the top plate.

[0015] In this technical solution, it should be noted that a support column is added to one side of the ultrasonic cleaning tank. The top of the support column contacts the bottom of the top plate, forming an auxiliary support structure for the top plate. The support column is vertically fixed to the ground, its height matching the lowest position of the support plate when it descends into the cleaning fluid. When the top plate descends to the set height with the support plate, the top of the support column completely contacts the bottom surface of the top plate, bearing the entire weight of the top plate, support plate, placement box, and parts. This transfers the static load originally borne by the lifting device (such as the first hydraulic cylinder) to the rigid support column, preventing the hydraulic cylinder from aging its seals or deforming its piston rod due to long-term static pressure. An elastic buffer pad (such as rubber or polyurethane) can be installed on the top of the support column, which can eliminate rigid collisions caused by installation errors and absorb the small displacements generated by ultrasonic vibrations during cleaning, ensuring the stability of the support plate without wobbling. This design, through the combination of "dynamic drive of the lifting device + static support of the support column," significantly improves the structural rigidity of the equipment in the cleaning state, extends the service life of the lifting device, and the limiting effect of the support column prevents the top plate from excessively descending and damaging the bottom components of the cleaning tank.

[0016] Preferably, the support plate has several water inlets running through it. At each of the four corners of the support plate, there is a baffle for limiting the four corners of the parts placement box; the baffle is an L-shaped structure adapted to the corners of the support plate. Each baffle slopes outward from bottom to top along the diagonal of the support plate.

[0017] In this technical solution, it should be noted that the support plate is equipped with water perforations and inclined L-shaped baffles, forming a functional composite structure: several water perforations penetrating the surface of the support plate ensure free flow of cleaning fluid, eliminating blind spots in the cleaning area where the bottom of the placement box contacts the support plate, and accelerating the drying of residual liquid after cleaning; the L-shaped baffles at the four corners are adapted to the corners of the support plate, and are inclined outward from bottom to top along the diagonal direction (e.g., inclination angle of 10° to 15°), with their bottoms close to the edge of the support plate to form a low-position limit, and their tops expanding outward to form a funnel-shaped guiding structure. When placing the parts placement box, the top of the inclined baffles can automatically guide the four corners of the placement box to align with the support plate, reducing manual centering operations; the outward tilting design avoids the rigid collision of traditional vertical baffles, making the placement box smoother when placed in, and allowing it to slide out along the inclined surface without lifting when removed, reducing operating resistance.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the convenient opening and closing of the cleaning box is achieved through the design of the box door with the linkage of the rotating shaft, and the lifting device is used to transform the traditional fixed low support plate into an adjustable height movable support, thus solving the problem of labor intensity caused by manual bending over to load and unload.

[0020] 2. In this utility model, the guide rail is designed to work in conjunction with the first hydraulic cylinder (or other lifting device). The hydraulic cylinder provides lifting power, and the guide rail bears lateral constraint. The combination of the two eliminates the risk of top plate tilting caused by long piston rod or load eccentricity, ensuring that the support plate always maintains a horizontal posture and avoiding damage to the parts inside the box due to shaking and collision.

[0021] 3. In this utility model, a support column is added to one side of the ultrasonic cleaning box, with its top contacting the bottom of the top plate to form an auxiliary support structure for the top plate: the support column is vertically fixed to the ground, and its height matches the lowest position when the support plate descends into the cleaning fluid. When the top plate descends to the set height with the support plate, the top of the support column is completely in contact with the bottom surface of the top plate, bearing the entire weight of the top plate, support plate, placement box and parts, transferring the static load originally borne by the lifting device (such as the first hydraulic cylinder) to the rigid support column, avoiding the hydraulic cylinder from bearing static pressure for a long time, which would cause the seals to age or the piston rod to deform.

[0022] 4. In this utility model, the L-shaped baffles at the four corners are adapted to the corners of the support plate, and are inclined outward from bottom to top along the diagonal direction. Their bottoms are close to the edge of the support plate to form a low-position limit, and their tops expand outward to form a funnel-shaped guiding structure. When placing the parts placement box, the top of the inclined baffle can automatically guide the four corners of the placement box to align with the support plate, reducing manual centering operations; the outward inclined design avoids the rigid collision of traditional vertical baffles, making the placement box smoother when placed in, and allowing it to slide out along the inclined surface without lifting when removed, reducing operating resistance.

[0036] Example

[0037] like Figures 1-5 As shown in the figure, an ultrasonic cleaning device is disclosed in this embodiment of the present invention, including an ultrasonic cleaning chamber 1. The ultrasonic cleaning chamber 1 has a support plate 3 and a chamber door 2 spaced apart at the top opening. The support plate 3 has a hinge seat 4 on its top, and a rotating shaft 5 is rotatably connected to the hinge seat 4. The chamber door 2 has a connecting plate 9 on its top, and the end of the connecting plate 9 away from the chamber door 2 is fixedly connected to the rotating shaft 5. The ultrasonic cleaning chamber 1 has a support plate 15 for supporting a parts placement box. A connecting rod 11 is provided on one side of the support plate 15. The top of the connecting rod 11 slides out of the support plate 3 and is connected to the top plate 10. The ultrasonic cleaning chamber 1 has a lifting device on one side for raising and lowering the top plate 10. It should be noted that the ultrasonic cleaning device achieves convenient loading and unloading of the parts placement box through the structure of the liftable support plate 15 and the linkage box door 2. The specific details are as follows: A support plate 3 is located on one side of the top opening of the ultrasonic cleaning box 1, and a box door 2 is located on the other side. The hinge seat 4 at the top of the support plate 3 is rotatably connected to the rotating shaft 5. The connecting plate 9 at the top of the box door 2 rigidly fixes the box door 2 to the rotating shaft 5, forming a rotating opening and closing structure with the rotating shaft 5 as the fulcrum. The operator can open and close the cleaning box by rotating the box door 2, and when the box door 2 is closed, it seals against the top of the cleaning box to prevent liquid splashing. The support plate 15 inside the cleaning box supports the parts placement box. A connecting rod 11 is vertically fixed on one side of the support plate 15. The top of the connecting rod 11 passes through the sliding hole of the support plate 3 and connects to the top plate 10, forming a rigid linkage structure between the support plate 15 and the top plate 10. A lifting device on one side of the box drives the top plate 10 to rise and fall vertically, thereby causing the connecting rod 11 and the support plate 15 to move synchronously. When it is necessary to place or remove the parts placement box, the lifting device drives the top plate 10 to rise, raising the support plate 15 to a higher position in the cleaning box (close to the height of a person standing and operating). The staff can place the parts-containing placement box smoothly on the support plate 15 or remove it from the support plate 15 without bending over. After placement, the lifting device drives the top plate 10 to fall, so that the support plate 15 carrying the placement box is immersed in the cleaning solution. At this time, the door 2 can be closed to start ultrasonic cleaning. This structure realizes the convenient opening and closing of the cleaning box through the door 2 design linked by the rotating shaft 5. The lifting device transforms the traditional fixed low-position support plate 15 into an adjustable height movable support, solving the labor intensity problem of manual bending over to load and unload.

[0038] like Figure 2As shown, in this embodiment, the lifting device includes a first hydraulic cylinder 12, which is located on one side of the ultrasonic cleaning chamber 1. The first hydraulic cylinder 12 is vertically arranged, and its piston rod is connected to the top plate 10. It should be noted that the lifting device uses a first hydraulic cylinder 12 vertically arranged on one side of the ultrasonic cleaning chamber 1, with its piston rod rigidly connected to the top plate 10. The lifting control of the top plate 10 is achieved through hydraulic drive: the first hydraulic cylinder 12 serves as a power source, using the pressure of hydraulic oil to push the piston rod in a linear motion, directly driving the top plate 10 to rise and fall vertically, thereby causing the support plate 15 to move synchronously up and down via the connecting rod 11. Because the hydraulic cylinder has the characteristics of large thrust and smooth operation, it can ensure that the support plate 15 maintains a horizontal posture during the lifting process, preventing parts inside the chamber from slipping due to tilting.

[0039] like Figure 2 As shown, in this embodiment, a guide rail 13 is also provided on one side of the ultrasonic cleaning box 1. The guide rail 13 is vertically arranged, and the top plate 10 is slidably sleeved on the guide rail 13. It should be noted that the addition of a vertical guide rail 13 on one side of the ultrasonic cleaning box 1, and the slidable sleeve of the top plate 10 on the guide rail 13, forms a rigid guide structure for the lifting and lowering movement of the top plate 10. The guide rail 13 is made of high-strength aluminum alloy or steel profile, and its length covers the entire lifting and lowering stroke of the support plate 15. The side of the top plate 10 is provided with a sliding sleeve or slider (such as a linear bearing or ball block) that cooperates with the guide rail 13, so that the top plate 10 moves linearly along the axis (vertical direction) of the guide rail 13 during the lifting and lowering process, effectively limiting lateral deviation. This design works in conjunction with the first hydraulic cylinder 12 (or other lifting device). The hydraulic cylinder provides lifting power, and the guide rail 13 provides lateral constraint. The combination of the two eliminates the risk of the top plate 10 tilting due to the long piston rod or load eccentricity, ensuring that the support plate 15 always maintains a horizontal posture and avoiding damage to the parts inside the box due to shaking and collision.

[0040] like Figure 2As shown, in this embodiment, a support frame 8 is also provided on one side of the ultrasonic cleaning box 1. A second hydraulic cylinder 7 is hinged to the top of the support frame 8, and a rotating plate 6 is hinged to the piston rod of the second hydraulic cylinder 7. The end of the rotating plate 6 away from the second hydraulic cylinder 7 is fixedly connected to the rotating shaft 5. It should be noted that the support frame 8 is provided on one side of the ultrasonic cleaning box 1, with the second hydraulic cylinder 7 hinged to its top. The piston rod is connected to the rotating plate 6 through a hinge structure, and the rotating shaft 5 is fixed to the other end of the rotating plate 6, forming an automated drive system for the box door 2: the support frame 8 serves as a basic support component, providing a hinge fulcrum for the second hydraulic cylinder 7; forming a kinematic chain of "cylinder body fixed - piston rod extension and retraction - rotating plate 6 rotation"; when the piston rod of the second hydraulic cylinder 7 retracts, it pushes the rotating plate 6 to rotate, causing the rotating shaft 5 fixed thereto to rotate synchronously, thereby causing the box door 2 to rotate counterclockwise around the rotating shaft 5 to open through the connecting plate 9; conversely, when the piston rod extends, the rotating plate 6 rotates downward, and the box door 2 rotates clockwise to close. This design converts the linear motion of the hydraulic cylinder into the rotational motion of the door 2, enabling the automatic opening and closing of the door 2 and avoiding manual operation. It is especially suitable for heavy-duty cleaning boxes or high-frequency use scenarios.

[0041] like Figure 1 As shown, in this embodiment, a support column 14 is also provided on one side of the ultrasonic cleaning box 1, and the top of the support column 14 contacts the bottom of the top plate 10. It should be noted that the addition of a support column 14 on one side of the ultrasonic cleaning box 1, with its top contacting the bottom of the top plate 10, forms an auxiliary support structure for the top plate 10: the support column 14 is vertically fixed to the ground, and its height matches the lowest position of the support plate 15 when it descends into the cleaning fluid. When the top plate 10 descends to the set height along with the support plate 15, the top of the support column 14 is completely in contact with the bottom surface of the top plate 10, bearing the entire weight of the top plate 10, the support plate 15, the placement box, and the parts. This transfers the static load originally borne by the lifting device (such as the first hydraulic cylinder 12) to the rigid support column 14, avoiding the aging of the seals or deformation of the piston rod caused by the hydraulic cylinder bearing static pressure for a long time. An elastic buffer pad (such as rubber or polyurethane material) can be provided on the top of the support column 14, which can eliminate rigid collisions caused by installation errors and absorb the small displacements generated by ultrasonic vibrations during the cleaning process, ensuring that the support plate 15 is stable and does not wobble. This design, through the combination of "dynamic drive of the lifting device + static support of the support column 14", significantly improves the structural rigidity of the equipment in the cleaning state and extends the service life of the lifting device. At the same time, the limiting function of the support column 14 can prevent the top plate 10 from falling excessively and damaging the bottom components of the cleaning tank.

[0042] like Figure 4 and Figure 5As shown, in this embodiment, the support plate 15 is provided with a plurality of water inlets 16. At each of the four corners of the support plate 15, there is a baffle 17 for limiting the four corners of the parts placement box. The baffle 17 is an L-shaped structure adapted to the corners of the support plate 15. Each baffle 17 is inclined outward from bottom to top along the diagonal of the support plate 15. It should be noted that the support plate 15 is equipped with water inlets 16 and inclined L-shaped baffles 17, forming a functional composite structure: the water inlets 16 penetrating the surface of the support plate 15 ensure free flow of cleaning fluid, eliminate blind spots in the cleaning area where the bottom of the placement box contacts the support plate 15, and accelerate the drying of residual liquid after cleaning; the L-shaped baffles 17 at the four corners are adapted to the corners of the support plate 15, and are inclined outward from bottom to top along the diagonal direction (e.g., inclination angle of 10° to 15°), with their bottoms close to the edge of the support plate 15 to form a low-position limit, and their tops expanding outward to form a funnel-shaped guiding structure. When placing the parts placement box, the top of the inclined baffles 17 can automatically guide the four corners of the placement box to align with the support plate 15, reducing manual centering operations; the outward tilting design avoids the rigid collision of the traditional vertical baffles 17, making the placement box smoother when placed in, and allowing it to slide out along the inclined surface without lifting when removed, reducing operating resistance.

[0043] The working principle of this utility model is as follows:

[0044] The complete working process of the ultrasonic cleaning device is as follows: The second hydraulic cylinder 7 is activated, and its piston rod retracts to drive the rotating plate 6 to rotate, which in turn drives the rotating shaft 5 to rotate, causing the box door 2 to rotate counterclockwise around the rotating shaft 5 and open automatically; at the same time, the piston rod of the first hydraulic cylinder 12 extends, and through the top plate 10 and the connecting rod 11, the support plate 15 is lifted along the vertical guide rail 13 to a height close to the human standing height (about 1.3 to 1.5m). The top of the inclined L-shaped baffles 17 at the four corners of the support plate 15 expands outward to form guide openings. The staff can easily push the placement box containing the railcar parts into the support plate 15 along the inclined surface of the baffle 17 without bending over. The four corners of the placement box are limited by the bottom of the L-shaped baffles 17 to ensure accurate positioning without deviation. After placement, the piston rod of the first hydraulic cylinder 12 retracts, causing the support plate 15 to descend smoothly along the guide rail 13. When the support plate 15 is immersed in the cleaning fluid to the set depth, the top of the support column 14 contacts the bottom surface of the top plate 10, bearing the entire weight of the support plate 15 and the placement box, reducing the static load on the hydraulic cylinder. Subsequently, the piston rod of the second hydraulic cylinder 7 extends, and the rotating plate 6 rotates downward to close the box door 2 clockwise and seal it with the top of the cleaning box. The ultrasonic transducer is activated, and the cleaning fluid flows freely through the water outlet 16 of the support plate 15, covering all surfaces of the parts inside the placement box for efficient cleaning. After cleaning, the second hydraulic cylinder 7 actuates again to open the box door 2, and the first hydraulic cylinder 12 lifts the support plate 15 to a high position. The residual liquid in the placement box is quickly drained through the water outlet 16, and the operator removes the placement box, completing the entire cleaning process.
