Description

Technical Field

[0001] This utility model relates to the field of engineering machinery cleaning equipment technology, and in particular to an engineering machinery frame cleaning device. Background Technology

[0002] During the production and maintenance of construction machinery (such as bulldozers), the surface of the main frame often accumulates a large amount of iron filings, sludge, and dust, requiring thorough cleaning before maintenance or painting. However, due to the large size of the main frame and the large space it occupies, there is no dedicated cleaning platform. Currently, there are two main methods for cleaning the frame: 1. Ground trench cleaning: Drainage trenches are dug on the ground, and collection pits are built. Wastewater is pumped away. This method requires large-scale civil engineering construction, is prone to damaging the ground structure, is costly, and has a fixed location, resulting in poor flexibility. 2. Ordinary platform washing: Washing on flat ground or low platforms results in sewage flowing everywhere, which is difficult to collect, leading to a dirty and messy working environment. In addition, iron filings and oil stains in the sewage will pollute the ground, making subsequent cleanup work heavy.

[0003] Therefore, existing technologies suffer from problems such as high construction costs, difficulty in sewage collection, poor working environment, and insufficient flexibility. Utility Model Content

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 4This application provides a cleaning device for engineering machinery frames, including a support platform 10, a enclosure 20, a ladder 30, and a sewage collection vehicle 40. The support platform 10 has a horizontal support plane 11, on which a grating plate 12 is laid. A sewage collection chamber 13 and support legs 14 are located at the bottom of the support plane 11. Sewage from cleaning the engineering machinery frame flows into the sewage collection chamber 13 through the gaps in the grating plate 12. A drainage pipe 131 is provided at the bottom of the sewage collection chamber 13 for discharging sewage from the chamber. The support legs 14 are located outside the sewage collection chamber 13 to support it to a predetermined height. This predetermined height can be 0.5-1.5 meters, creating an operating space.

[0023] The enclosure 20 is vertically connected to the outer ring of the top of the support platform 10 to minimize the splashing of cleaning water. The enclosure 20 also has a notch 201 to facilitate the lifting and lowering of the construction machinery frame. A ladder 30 is located at the notch 201, allowing workers to climb from the ground to the support platform 10 for easy access to clean the construction machinery frame.

[0024] The sewage collection vehicle 40 is equipped with a top-open water tank 401 and casters 41 at the bottom for transporting sewage discharged from the drain pipe 131 below the sewage collection chamber 13. During operation, when the sewage collection vehicle 40 is in position, the drain pipe 131 extends directly above or into the water tank 401, allowing sewage to flow directly into the water tank 401.

[0025] Therefore, the engineering machinery frame cleaning device provided in this application does not require ground trenching, has extremely low cost, is easy to manufacture and maintain, completely avoids the large-scale civil engineering of traditional methods, and can be quickly deployed using existing hardened ground, which can significantly reduce construction costs and time. Meanwhile, it is highly flexible, with the carrying platform able to be moved and placed in different locations within the workshop. The wastewater collection vehicle can be easily moved for centralized treatment without affecting continuous operation. At the same time, it can achieve targeted and centralized collection of sewage, ensuring efficient collection of sewage and improving the cleaning operation environment.

[0026] Considering that most construction machinery, including bulldozers, is rectangular in shape, in one embodiment, the carrying platform 10 is rectangular, and the enclosure 20 is vertically connected to the two opposite long sides and one of the short sides of the carrying platform 10, and forms the enclosure gap 201 at the other short side, thereby making fuller use of the cleaning space.

[0027] In one embodiment, the bottom wall of the sewage collection chamber 13 consists of two symmetrically distributed sloping base plates 132 along its length. The two sloping base plates 132 extend symmetrically at an incline and connect at the midpoint of the length of the supporting platform 10, with the connection point being the highest point. The lowest point of the sloping base plate 132 connects to the left and right side walls of the sewage collection chamber 13, and the drainage pipe 131 is located at the lowest point. In this way, cleaning wastewater will quickly flow and converge along the sloping base plates 132 and be directionally discharged into the sewage collection vehicle 40 through the drainage pipe 131 at the lowest point, achieving complete sewage control. Furthermore, the side enclosure 20 significantly reduces ground pollution and sewage overflow, resulting in a cleaner work site.

[0028] In one embodiment, the drainage pipe 131 is equipped with a drainage valve to facilitate control of the drainage timing. The drainage valve is opened after the sewage collection vehicle 40 has moved into place, making the operation more convenient.

[0029] In one embodiment, one end of the sewage collection vehicle 40 is provided with an operating handle 42 to facilitate pushing and pulling the sewage collection vehicle 40. The other end of the sewage collection vehicle 40 is provided with a drain pipe 43, which is connected to the bottom of the water tank 401 and is equipped with a drain valve for draining sewage.

[0030] During the cleaning operation, operators hoist the frame of the construction machinery onto the grating plate 12 of the support platform 10. Workers then climb onto the support platform 10 using a ladder 30 and use a high-pressure spray gun connected to warm water to rinse the frame. The ladder 30 is then removed. The sewage collection truck 40 is pushed from both ends of the support platform 10 to below the sewage collection chamber 13, directly facing the drainage pipe 131. Sewage containing iron filings and oil passes through the grating plate 12 and falls onto the slope base plate 132, flowing rapidly down the slope towards the drainage pipe 131, ultimately flowing into the sewage collection truck 40 below. When the sewage collection truck 40 is nearly full, the drainage valve is closed, and the sewage collection truck 40 is moved. After it is in place, the drain pipe 43 is opened to release the sewage. After further treatment, it is moved back below the support platform 10, enabling continuous operation.

[0031] In one embodiment, the upper part of the water tank 401 is provided with a support frame 44 near the operating handle. The support frame 44 extends horizontally and is provided with a filter plate, thereby filtering out larger particles of impurities.

[0032] In one embodiment, the support frame 44 includes a first strip steel plate 441 and a second strip steel plate 442, wherein the first strip steel plate 441 is horizontally disposed on the inner side wall of the water tank 401 near the end of the operating handle 42, wherein the second strip steel plate 442 is parallel to the first strip steel plate 441 and is located near the middle of the water tank 401 in the horizontal direction, and the second strip steel plate 442 is vertically connected to the front and rear inner walls of the water tank 401.

[0033] More preferably, the support frame 44 further includes a plurality of (e.g., 2-4) connecting stiffeners 443, which are horizontally connected between the first strip steel plate 441 and the second strip steel plate 442 and are evenly distributed between the front and rear inner walls of the water tank 401. Together with the first strip steel plate 441 and the second strip steel plate 442, they form a support plane to improve the support strength and stability of the entire support frame 44.

[0034] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
