[0035] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, what is described is only a part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, it should be noted that the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] For mechanical equipment such as hydraulic cylinders, their parts are prone to iron powder, iron filings and other pollutants during the production process, and the parts of the mechanical equipment need to be cleaned to remove or reduce these pollutants. At present, the cleaning method mainly relies on manual cleaning by operators; however, manual cleaning has high labor intensity and low cleaning efficiency; therefore, there is an urgent need for a cleaning device that can reduce labor intensity and improve cleaning efficiency.

[0039] In order to solve the above technical problems, the utility model proposes a mechanical equipment parts cleaning device.

[0040] See also Figure 1-7 In one embodiment of the utility model, the mechanical equipment parts cleaning device is used to clean mechanical equipment parts (not shown in the drawings); specifically, the mechanical equipment parts cleaning device includes:

[0041] A water tank 1, the water tank 1 carries a cleaning liquid (not shown in the drawings); in order to improve the cleaning effect of the cleaning liquid on pollutants such as oil, the cleaning liquid in this embodiment is alkaline;

[0042] The cleaning box 2, the bottom plate 201 of the cleaning box 2 is provided with a drainage hole 2011, and the drainage hole 2011 is communicated with the water storage tank 1; it can be understood that the bottom plate 201 is a plate located at the bottom of the cleaning box 2;

[0043] The carrier plate 3 is used to carry mechanical equipment parts; the carrier plate 3 is rotatably connected to the inside of the cleaning box 2 through the supporting assembly 6, and a drainage gap 4 is provided between the carrier plate 3 and the box bottom plate 201; a water leakage hole 301 is provided through the bottom of the carrier plate 3, and the water leakage hole 301, the drainage gap 4 and the drainage hole 2011 are connected in sequence;

[0044] A rotary drive device 5, the driving end of which is connected to the carrier plate 3, and the rotary drive device 5 is used to drive the carrier plate 3 to rotate relative to the cleaning box 2;

[0045] The spray component 7 is used to extract the cleaning liquid in the water tank 1 and spray it onto the mechanical equipment parts on the supporting plate 3.

[0046] The technical solution of the utility model is to rotatably connect the carrier plate 3 to the inside of the cleaning box 2 through the supporting component 6; during the cleaning operation, after the mechanical equipment parts are placed on the carrier plate 3, the spray component 7 is started, and the cleaning liquid in the water tank 1 is extracted by the spray component 7, and the mechanical equipment parts on the carrier plate 3 are sprayed and rinsed; during this period, the rotary drive device 5 drives the carrier plate 3 to rotate, so that the mechanical equipment parts can be sprayed and rinsed in multiple directions, which is beneficial to improve the cleaning effect. The cleaning liquid after spraying and rinsing flows back to the water tank 1 through the leakage hole 301, the drainage gap 4 and the drainage hole 2011 in turn, so that the cleaning liquid can be recycled, which is energy-saving and environmentally friendly. The above-mentioned cleaning operation process does not require manual intervention, which can reduce labor intensity and improve cleaning efficiency.

[0047] Specifically, the cleaning tank 2 is carried on the water tank 1, and the drainage hole 2011 is located above the water tank 1. This arrangement allows the cleaning liquid to fall directly into the water tank 1 below it through the drainage hole 2011 by its own gravity, without the need to set up an additional pumping device for the reflux of the cleaning liquid, which is beneficial to energy saving and environmental protection. It is understandable that, considering that the cleaning liquid will be accompanied by pollutants originally adhered to the surface of the mechanical equipment parts after a spray cleaning, in order to avoid the second spray cleaning to spray its pollutants again onto the surface of the mechanical equipment parts, a filtering device (not shown in the drawings) should be provided between the drainage hole 2011 and the water tank 1, and the pollutants in the cleaning liquid are filtered and purified by the filtering device.

[0048] Specifically, the inner wall surface of the cleaning box 2 is provided with an anti-corrosion protective layer (not shown in the drawings); in this arrangement, considering the selection of an alkaline cleaning liquid, the splashing cleaning liquid adheres to the inner wall surface of the cleaning box 2, which will cause corrosion and rust on the internal surface of the cleaning box 2. Therefore, an anti-corrosion protective layer is provided to effectively protect the cleaning box 2, thereby extending the service life of the present application.

[0049] Specifically, a door member 202 is provided on one side of the cleaning box 2. With this arrangement, after placing the mechanical equipment parts on the carrier plate 3, the operator closes the door member 202 to close the cleaning box 2, thereby preventing the cleaning liquid from splashing out of the cleaning box 2 and polluting the working environment.

[0050] For details, please refer to the attached Figure 4-5 The driving end of the rotation driving device 5 is provided with a driving shaft 501; the bottom of the carrier plate 3 is provided with a transmission shaft 303, the driving shaft 501 is coaxially aligned with the transmission shaft 303, and the driving shaft 501 and the transmission shaft 303 are connected to each other through a sleeve 502. In this embodiment, the above-mentioned rotation driving device 5 can be selected as a servo motor.

[0051] There are many specific structures of the supporting assembly 6. In this embodiment, refer to the attached Figure 4-5 The supporting assembly 6 includes an outer sleeve member 601 and an inner sleeve member 602 which are coaxially arranged. The outer sleeve member 601 is rotatably connected to the inner sleeve member 602. There is a horizontal height difference between the outer sleeve member 601 and the inner sleeve member 602, and the outer sleeve member 601 is at least partially sleeved on the outer side of the inner sleeve member 602. The inner sleeve member 602 is provided with a through hole portion 6021 in the axial direction, and the through hole portion 6021 is used for the transmission shaft 303 to pass through. The bottom of the inner sleeve member 602 is connected to the bottom plate 201 of the box, and the top of the outer sleeve member 601 is connected to the bottom of the carrier plate 3. With such an arrangement, the supporting assembly 6 can effectively support the carrier plate 3 without affecting the mutual rotation between the carrier plate 3 and the cleaning box 2. The structure is simple and practical.

[0052] It can be understood that there is a horizontal height difference between the outer sleeve member 601 and the inner sleeve member 602, and the outer sleeve member 601 is at least partially sleeved on the outside of the inner sleeve member 602. Specifically, the top end of the outer sleeve member 601 is higher than the top end of the inner sleeve member 602, and the bottom end of the outer sleeve member 601 is higher than the bottom end of the inner sleeve member 602, and the outer sleeve member 601 and the inner sleeve member 602 have overlapping areas in the height direction.

[0053] Furthermore, a disc-shaped member 603 is provided at the bottom of the inner sleeve member 602, and the cross-sectional area of ​​the disc-shaped member 603 is larger than the cross-sectional area of ​​the inner sleeve member 602, and the inner sleeve member 602 is fixedly connected to the box bottom plate 201 through the disc-shaped member 603; in this way, on the one hand, the connection area between the inner sleeve member 602 and the box bottom plate 201 is increased by the disc-shaped member 603 with a larger cross-sectional area, so that the supporting assembly 6 can be stably placed on the box bottom plate 201; on the other hand, the disc-shaped member 603 is used as the placement surface of the thrust roller bearing 604 that appears below, so that the outer sleeve member 601 and the inner sleeve member 602 can be effectively connected.

[0054] Furthermore, a notch portion 6011 is provided at the bottom of the outer sleeve member 601; the supporting assembly 6 also includes a thrust roller bearing 604, the bottom end of the inner ring of the thrust roller bearing 604 is supported on the disc-shaped member 603, and the inner ring of the thrust roller bearing 604 is sleeved on the outer side of the inner sleeve member 602; the top end of the outer ring of the thrust roller bearing 604 is abutted against the inner top of the notch portion 6011, and the outer ring of the thrust roller bearing 604 is sleeved on the inner side of the notch portion 6011; in this arrangement, since the thrust roller bearing 604 can withstand the axial load and the combined axial and radial loads, the above-mentioned structure can support the outer sleeve member 601 by using the disc-shaped member 603 while satisfying the mutual rotation of the outer sleeve member 601 and the inner sleeve member 602, thereby realizing that the supporting plate 3 is supported on the bottom plate 201 of the box, and the supporting plate 3 can rotate relative to the cleaning box 2, and the structure is simple and practical.

[0055] Further, a first deep groove ball bearing 605 is fixedly arranged inside the through hole portion 6021, and the transmission shaft 303 is rotatably connected to the inner sleeve member 602 through the first deep groove ball bearing 605; and / or, a second deep groove ball bearing 606 is arranged between the middle portion of the outer sleeve member 601 and the inner sleeve member 602. In this arrangement, the first deep groove ball bearing 605 and the second deep groove ball bearing 606 have the characteristics of small friction resistance and high rotation speed. The first deep groove ball bearing 605 allows the transmission shaft 303 and the inner sleeve member 602 to rotate relatively smoothly, and the second deep groove ball bearing 606 allows the outer sleeve member 601 and the inner sleeve member 602 to rotate relatively smoothly, and the structure is simple and practical.

[0056] It should be noted that, since the above-mentioned thrust roller bearing 604, the first deep groove ball bearing 605 and the second deep groove ball bearing 606 all belong to the prior art, the present application will not further elaborate on their structures.

[0057] Furthermore, a plurality of reinforcing plates 607 are provided between the outer side of the outer sleeve 601 and the bottom of the carrier plate 3, and the plurality of reinforcing plates 607 are arranged in a ring with equal distances around the axis of the carrier plate 3. In this way, the connection area between the outer sleeve 601 and the carrier plate 3 is increased by a plurality of reinforcing plates 607, thereby increasing the connection strength between the outer sleeve 601 and the carrier plate 3.

[0058] There are many specific structures of the carrier plate 3. Figure 2 The edge of the carrier plate 3 is provided with a baffle plate 302 in an annular shape, and the top of the baffle plate 302 is higher than the surface of the carrier plate 3. In this way, the baffle plate 302 is provided to block the mechanical equipment parts, so that the mechanical equipment parts can be prevented from being thrown out of the carrier plate 3 due to the centrifugal force during the rotation of the carrier plate 3.

[0059] Furthermore, the supporting plate 3 is provided with a plurality of leakage holes 301, and the plurality of leakage holes 301 are arranged with each other to form a multi-layer annular structure with the axis of the supporting plate 3 as the center of the circle. By setting up a plurality of leakage holes 301 in this way, it is ensured that the cleaning liquid remaining on the supporting plate 3 after cleaning can all flow through the leakage holes 301 to the drainage gap 4, and then flow back to the water tank 1, thereby avoiding the accumulation of cleaning liquid on the supporting plate 3.

[0060] As a preferred solution of the above embodiment, refer to the attached Figure 2-4 The spray assembly 7 includes a water pumping device 701 and at least four groups of spray pipes 702. The at least four groups of spray pipes 702 are arranged around the outer side of the carrier plate 3. The spray pipes 702 are provided with a plurality of spray holes 7021, and the spray holes 7021 face the carrier plate 3. In this way, the water pumping device 701 is used to inject the cleaning liquid in the water tank 1 into the spray pipe 702, so that the cleaning liquid is sprayed out from the spray holes 7021 to spray and rinse the mechanical equipment parts located on the carrier plate 3. At the same time, the cleaning liquid sprayed out from the spray holes 7021 will generate a certain impact force and pressure, thereby effectively cleaning the iron powder and iron filings and other pollutants attached to the surface of the mechanical equipment parts. In this way, the mechanical equipment parts are sprayed by combining multiple groups of spray pipes 702, which is conducive to improving the cleaning effect of the mechanical equipment parts. In this embodiment, the above-mentioned spray pipes 702 are arranged in four groups.

[0061] Further, see Attachment Figure 6 The spray pipe 702 includes a vertical section 7022 and an inclined section 7023. The cleaning liquid is sprayed laterally to the mechanical equipment parts through the vertical section 7022, and the cleaning liquid is sprayed downward to the mechanical equipment parts through the inclined section 7023. The combination of the two allows the sides and tops of the mechanical equipment parts to be sprayed with the cleaning liquid, further improving the cleaning effect on the mechanical equipment parts.

[0062] As a preferred solution of the above embodiment, refer to the attached Figure 7 The water tank 1 is provided with a heating component 8 inside, and the heating component 8 is used to heat the cleaning liquid; the heating component 8 includes at least two groups of heating tubes 801, and the at least two groups of heating tubes 801 are installed on a tube support 802, and the tube support 802 is arranged at the bottom of the water tank 1. In this way, the cleaning liquid in the water tank 1 is heated to a certain temperature by the heating component 8, and the cleaning liquid with a certain temperature is used to improve the cleaning effect of oily pollutants. In this embodiment, the above-mentioned heating tubes 801 are arranged in two.

[0063] It should be noted that other contents of the mechanical equipment parts cleaning device disclosed in the utility model are prior art and will not be repeated here.
