Description

Technical Field

[0001] The invention relates to an ultrasonic cleaning machine for locomotive parts, belonging to the technical field of ultrasonic cleaning. Background Art

[0002] With the continuous development of the cleaning industry, more and more industries have begun to use ultrasonic cleaning machines. The principle of ultrasonic cleaning machines is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the cleaning liquid. The ultrasonic wave radiates forward in the cleaning liquid in a sparse and dense manner, causing the liquid to flow and generate tens of thousands of tiny bubbles with a diameter of 50-500μm. The tiny bubbles in the liquid vibrate under the action of the sound field, promoting the dissolution of dirt on the surface of the cleaning object while vibrating the dirt off the surface of the object, thereby achieving cleaning. At present, during the maintenance of locomotive parts, after the ultrasonic cleaning machine cleans the locomotive parts, a large amount of dirt remains in the cleaning chamber and needs to be cleaned. At the same time, the locomotive parts taken out of the cleaning chamber also need to be cleaned to wash away the traces of sewage remaining on the surface of the parts. The two rinses with water not only waste water resources, but also increase the workload of the staff. Summary of the invention

DETAILED DESCRIPTION

[0029] The following is a clear and complete description of the technical solutions in the implementation of the present invention in conjunction with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 5 As shown, an ultrasonic cleaning machine for locomotive parts provided by an embodiment of the present invention comprises a housing 1 and a cleaning chamber 11 installed in the housing 1. The cleaning chamber 11 is cylindrical in shape, has a funnel-shaped bottom and an open top, which is convenient for collecting dirt. A drain port 13 is connected to the bottom center of the cleaning chamber 11. A plurality of ultrasonic transducers 14 are arranged on the cavity wall below the bottom of the cleaning chamber 11. The ultrasonic transducers 14 are very mature products and can be used by connecting a power supply. An upper cover 2 is arranged above the cleaning chamber 11. A cover handle 35 is connected to the top of the upper cover 2. A handle for opening and closing the upper cover 2 is arranged between the cover handle 35 and the top of the housing 1. The cover opening device 3; the upper cover 2 is provided with a motor 21 and a first pipe 22, and the bottom of the first pipe 22 is provided with a plurality of rotating nozzles 221, and the rotating nozzles 221 can spray the water transported by the first pipe 22 in the cleaning chamber 11 at multiple angles. The rotating nozzles 221 are also very mature products and the structure description is not given here. The output end of the motor 21 is connected to a brushing device matched with the cleaning chamber 11, and the brushing device includes an annular frame 25 and two brushing frames 26 with the same structure arranged below the annular frame 25 for brushing the inner wall of the cleaning chamber 11, and the brushing frame 26 and the annular frame 25 are connected by a telescopic rod 27.

[0031] like Figures 6 to 8As shown, the annular frame 25 and the brush rack 26 can be seen from a top view that the annular frame 25 has space for accommodating mechanical parts. When cleaning locomotive parts, the parts are placed at the center of the bottom of the cleaning chamber 11, and the ultrasonic transducer 14 is activated. When the ultrasonic wave propagates in the cleaning liquid in the cleaning chamber 11, it produces physical effects such as cavitation, radiation pressure, and acoustic flow, which have a peeling effect on the dirt on the locomotive parts, and can promote the chemical reaction between the cleaning liquid and the dirt to achieve the purpose of cleaning the object. After the cleaning is completed, the waste water is discharged through the drain port 13. The upper cover 2 is pressed down, and the brush rack 26 is placed into the cleaning chamber 11 by using the telescopic rod 27. At this time, the brush rack 26 surrounds the outside of the locomotive parts. The motor 21 is started, and the brush rack 26 rotates under the drive of the motor 21 to continuously scrub the inner wall of the cleaning chamber 11. At the same time, clean water is transported in the first pipe 22, and the clean water is sprayed on the inner wall of the cleaning chamber 11 and the mechanical parts through the rotating nozzle 221. The sewage on the locomotive parts and the inner wall of the cleaning chamber 11 is discharged through the drain port 13, so that the cleaning chamber 11 is cleaned while the locomotive parts are flushed, saving labor and water resources.

[0032] Furthermore, the output end of the motor 21 is connected to a rotary joint 24 , a rotary shaft 241 of the rotary joint 24 is fixedly connected to the annular frame 25 , a side of the rotary joint 24 is connected to a second pipe 23 , and an input end of the second pipe 23 extends out of the upper cover 2 .

[0033] By setting the rotary joint 24, the annular frame 25 and the rotating shaft 241 are relatively fixed. At this time, the following scheme can be adopted: the annular frame 25 extends out from the bottom end of the rotating shaft 241, and clean water is input into the rotary joint 24 through the second pipe 23. The clean water flows out directly from the bottom end of the rotating shaft 241 to spray the cleaning chamber 11 and the locomotive parts. In order to improve the spraying effect, a rotating nozzle can also be set at the bottom end of the rotating shaft 241 to spray the cleaning chamber 11 and the locomotive parts at multiple angles; a water spray pipe can also be connected to the end of the rotating shaft 241 extending out of the annular frame 25, and the water spray pipe is connected to the brush frame 2 6, clean water enters from the second pipe 23 and is finally sprayed out from multiple water spray pipes to spray the cleaning chamber 11 and locomotive parts; a flow channel can also be opened inside the annular frame 25, the flow channel in the rotating shaft 241 is connected with the flow channel of the annular frame 25, and multiple spray holes are opened on the bottom surface of the annular frame 25, and clean water is input from the second pipe 23. After flowing through the flow channel of the rotating shaft 241, the clean water enters the flow channel in the annular frame 25 and is finally sprayed out from the spray holes to spray the cleaning chamber 11 and locomotive parts.

[0034] Furthermore, a pipe connecting the inner cavity of the rotating shaft 241 and the inner cavity of the telescopic rod 27 is provided on the annular frame 25 , and the telescopic rod 27 is driven to be telescopic by gas or liquid input from the second pipe 23 .

[0035] The telescopic rod 27 may be an electric telescopic rod 27. Considering that the scrubbing device needs to be in contact with water, which may affect the electric telescopic rod 27, the extension and contraction of the telescopic rod 27 can be controlled by providing a rotating joint 24 and a pipe connecting the inner cavity of the rotating shaft 241 and the inner cavity of the telescopic rod 27, and inputting liquid or gas from the second pipe 23. When liquid is input into the second pipe 23, the liquid flows through the rotating joint 24 and the annular frame 25 and enters the inner cavity of the telescopic rod 27. The inner cavity of the telescopic rod 27 is affected by water pressure, and the multi-section telescopic rod extends. When the liquid is extracted from the second pipe 23, negative pressure is generated in the multi-section telescopic rod, and the telescopic rod 27 contracts. The principle of using gas is the same as this, and the principle of the hydraulic cylinder can be referred to.

[0036] Furthermore, the brush rack 26 includes a plurality of brush plates 261, and the brush plates 261 are connected to the annular rack 25 through telescopic rods 27; when all the telescopic rods 27 are extended, the brush rack 26 as a whole is inclined and in an arc shape that matches the wall of the cleaning chamber 11, and when all the telescopic rods 27 are retracted, the brush rack 26 as a whole is in a semi-circular shape that matches the wall of the cleaning chamber 11.

[0037] like Figures 6 to 10 As shown, when all telescopic rods 27 are extended, any two adjacent scrubbing plates 261 are connected in sequence, and the overall structure forms an arc that matches the curvature of the wall of the cleaning chamber 11, and is inclined. The highest scrubbing plate 261 is located at the upper part of the cleaning chamber 11, and the lowest scrubbing plate 261 is located at the lower part of the cleaning chamber 11. The two scrubbing racks 26 are located on both sides of the annular rack 25, respectively, so that the weight distribution of the annular rack 25 is more uniform. The inclined shape of the scrubbing rack 26 enables the scrubbing device to further promote the brushing of dirt from above to below when rotating. Fig. 9 As shown, when the telescopic rod 27 is retracted, the overall height of the scrubbing frame 26 is only the height of a scrubbing plate 261, which facilitates the folding and storage of the scrubbing frame 26 without affecting the placement and removal of motorcycle parts.

[0038] Furthermore, bristles 28 are provided on one side of the scrubbing plate 261 facing the wall of the cleaning chamber 11 .

[0039] The bristles 28 facilitate brushing the wall of the cleaning cavity 11 .

[0040] Furthermore, a partition 29 is provided in the upper cover 2 , and the partition 29 separates the motor 21 from the scrubbing device, and the rotating spray head 221 is located below the partition 29 .

[0041] The partition 29 can prevent water from splashing onto the motor 21 when the rotating nozzle 221 sprays the cleaning chamber 11 and the locomotive parts below.

[0042] Furthermore, a sealed groove 12 matched with the upper cover 2 is provided on the housing 1 outside the cleaning chamber 11 , and a water flow groove 121 leading to the cleaning chamber 11 is provided on the sealed groove 12 .

[0043] By providing the sealed groove 12, when the upper cover 2 is pressed down and closed, the sealed groove 12 can further improve the airtightness between the upper cover 2 and the cleaning chamber 11 to prevent water from splashing around. The water flow groove 121 can allow water falling along the edge of the upper cover 2 to enter the cleaning chamber 11 from the water flow groove 121, thereby reducing or avoiding water accumulation in the sealed groove 12.

[0044] Furthermore, the cover opening device 3 includes a mounting platform 32 arranged on the casing 1, the cover handle 35 is hinged on a hinge seat 34 on the mounting platform 32, and a second push rod 36 hinged to the cover handle 35 is hinged on the mounting platform 32 between the hinge seat 34 and the upper cover 2.

[0045] like Figure 1 and Figure 5 As shown, the cover handle 35 is pushed upward or pulled downward by the second push rod 36, so that the upper cover 2 is opened upward or closed downward, which is easy to operate.

[0046] Furthermore, a first push rod 31 is vertically arranged in the housing 1 , the mounting platform 32 is fixed on the output end of the first push rod 31 , and a guide rod 33 is provided between the mounting platform 32 and the housing 1 .

[0047] When the scrubbing device is in the retracted state, it may not be completely retracted into the upper cover 2 according to actual conditions, so that when the upper cover 2 is opened or closed, the scrubbing device and the inner wall of the cleaning chamber 11 interfere with each other. The upper cover 2 is driven to move up and down as a whole by the first push rod 31 pushing the mounting platform 32 upward or pulling it down, thereby solving the possible interference problem.

[0048] Furthermore, a side of the mounting platform 32 close to the upper cover 2 is provided with an arc-shaped limiting backrest 321 that matches the upper cover 2 .

[0049] The limiting backrest 321 can be used for positioning the upper cover 2 when it is pressed down to close, and assists the work of the second push rod 36 .

[0050] Working principle: When the upper cover 2 is opened, the cleaning liquid is injected into the cleaning chamber 11, and then the locomotive parts to be cleaned are placed in the center of the bottom of the cleaning chamber 11. An additional support frame can be placed in the cleaning chamber 11 to support locomotive parts with irregular shapes. The locomotive parts and the support frame as a whole do not interfere with the brushing device. The ultrasonic transducer 14 is started to start ultrasonic cleaning of the locomotive parts. After the cleaning is completed, the cleaning liquid is discharged through the drain port 13, and then the second push rod 36 is started. The upper cover 2 is flipped to a position in contact with the limit backrest 321, and then the first push rod 31 is started, and the upper cover 2 moves downward as a whole to cooperate with the closed groove 12. Liquid or gas is input into the rotary joint 24 through the second pipe 23. The liquid or gas flows through the rotary joint 24 and the annular frame 25 and enters the inner cavity of the telescopic rod 27. The inner cavity of the telescopic rod 27 is subjected to hydraulic or pneumatic pressure, and multiple telescopic joints extend, and the telescopic rod 27 extends. Driven by the telescopic rod 27, a number of brush plates 261 move downward, and finally form the following Figure 5 The arc-shaped brush rack 26 shown in the figure is in contact with the inner wall of the cleaning chamber 11 as a whole, so the motorcycle parts located in the middle of the cleaning chamber 11 do not interfere with the brush rack 26. The motor 21 is started, and the brush rack 26 starts to rotate to clean the inner wall of the cleaning chamber 11. At the same time, clean water is input into the first pipe 22, and the cleaning chamber 11 and the motorcycle parts are sprayed through the rotating nozzle 221 to wash away the remaining stains. Then the telescopic rod 27 is retracted so that the brush rack 26 is like Fig.10 Then, the first push rod 31 and the second push rod 36 are activated to open the upper cover 2 and take out the cleaned motorcycle parts.
