Description

Technical Field

[0001] This utility model relates to the field of vehicle chassis maintenance technology, and in particular to a cleaning tool for the chassis cavity of urban rail vehicles. Background Technology

[0002] The underframe cavity of an urban rail vehicle refers to the hollow space or passage formed in the underframe structure of an urban rail vehicle, which is usually composed of various beams, floor and other components of the underframe.

[0003] like Figure 5 As shown, the existing cavity has a triangular cubic structure with a relatively small inner wall space. If dust or foreign objects fall into the cavity, it is difficult to remove the foreign objects or clean the dust. Therefore, there is often some inconvenience in the actual maintenance of the cavity. So we propose a cleaning tool for the cavity of the urban rail vehicle underframe to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which makes it difficult to remove foreign objects or clean dust when they fall into the cavity. Therefore, a cleaning tool for the cavity of the underframe of urban rail vehicles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning tool for the underframe cavity of an urban rail vehicle includes a tool body disposed inside the cavity body. The tool body has a triangular cubic structure and maintains contact with the inner wall of the cavity body. An installation cavity is provided on the tool body.

[0007] The bottom inner wall of the mounting cavity is symmetrically provided with a first mounting port, and a bottom arc-shaped blade is fixedly installed in the first mounting port.

[0008] Two second mounting ports are symmetrically opened on the inclined inner wall of the mounting cavity, and a side arc-shaped blade is fixedly installed in the second mounting port.

[0009] In one possible design, the blade body is an isosceles triangular cube structure with a base length of 100 mm, a height of 60 mm, an overall length of 180 mm, and a top length of 50 mm.

[0010] In one possible design, a traction plate is fixedly installed in the central area of ​​the mounting cavity, and the traction plate has a traction hole for installing a traction rope.

[0011] The traction rope passes through the traction hole and forms a fixed connection with the traction plate, and extends both ends of the traction rope out of both sides of the cavity body. By driving the traction rope, the cutter body can move laterally back and forth in the cavity body, thereby using the side arc-shaped cutter blades and bottom arc-shaped cutter blades set on the cutter body to clean the inner wall of the cavity body.

[0012] In one possible design, the wall thickness of the blade body is 5 mm.

[0013] In one possible design, buckles are provided on both sides of the traction plate for fixing to the traction rope, so as to achieve a stable fixed connection between the traction plate and the traction rope.

[0014] In this application, before use, the traction rope is passed through the traction plate, with the length of the traction rope passing through being half the total length. Buckles are installed on both sides of the traction plate, and the traction rope is fixedly connected to the traction plate to achieve the purpose of fixing the traction plate and the traction rope. Then, one end of the traction rope is passed through the outside of the cavity body. When the blade reaches the cavity opening body, the blade is slowly placed into the cavity body, and the two ends of the traction rope are pulled to make the blade move left and right in the cavity. At this time, the bottom arc-shaped blade and the side arc-shaped blade can form a scraping effect with the inner wall of the cavity body, thereby achieving the purpose of removing foreign objects or dust inside the cavity body.

[0015] Beneficial effects: In this utility model, the cleaning knife for the underframe cavity of urban rail vehicles, through the bottom arc-shaped blade, can achieve a scraping effect on the bottom of the mounting cavity when the knife body moves laterally in the mounting cavity, thereby cleaning the bottom inner wall of the mounting cavity;

[0016] In this utility model, the cleaning tool for the underframe cavity of a city rail vehicle, through the side arc-shaped blade, can achieve a scraping effect on the side inner wall of the mounting cavity when the blade body moves laterally in the mounting cavity, thereby cleaning the side inner wall of the mounting cavity.

[0017] This utility model is mainly used for removing foreign objects inside the underframe cavity of urban rail vehicles. It can effectively remove aluminum slag, chip residue, debris and other foreign objects from the cavity, effectively ensuring the cleanliness of the cavity, reducing the impact of foreign objects on the cables inside the cavity, and thus improving the overall work quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In one embodiment: Refer to Figure 1-5 A cutting tool includes a blade body 1 disposed inside a cavity body 7. The blade body 1 adopts a triangular cubic structure, specifically an isosceles triangular cubic, with a base length of 100 mm, a height of 60 mm, an overall length of 180 mm, a top length of 50 mm, and a wall thickness of 5 mm, ensuring a balance between structural strength and lightweight requirements. The blade body 1 maintains contact with the inner wall of the cavity body 7 to achieve effective coverage during cleaning.

[0026] The blade body 1 has a mounting cavity 2. Two first mounting openings are symmetrically formed on the bottom inner wall of the mounting cavity 2. A bottom arc-shaped blade 4 is fixedly mounted in each first mounting opening by welding. The curvature of the blade matches the bottom contour of the cavity body 7, ensuring no blind spots during cleaning. Two second mounting openings are symmetrically formed on the inclined inner wall of the mounting cavity 2. Similarly, a side arc-shaped blade 3 is fixedly mounted in each second mounting opening by welding. The curvature of the blade matches the side wall contour of the cavity body 7, achieving side wall cleaning.

[0027] The traction plate 5 is fixedly installed in the central area of ​​the mounting cavity 2 with bolts. The traction plate 5 has traction holes 6, the diameter of which is set according to the specifications of the traction rope to ensure smooth passage. After passing through the traction holes 6, the traction rope is fixedly connected to the traction plate 5 by double-strand winding. Both ends of the traction rope extend to the outside of the cavity body 7, with the extension length meeting the operating space requirements. Driven by external force, the traction rope can cause the blade 1 to move laterally back and forth within the cavity body 7. During this movement, the side arc-shaped blade 3 and the bottom arc-shaped blade 4 continuously scrape the inner wall of the cavity, achieving a cleaning effect.

[0028] This application can be used in the field of vehicle chassis maintenance technology, or in other fields applicable to this application.

[0029] In another embodiment: Reference Figure 4 Based on the above embodiments, an improvement is made to a cleaning tool for the underframe cavity of urban rail vehicles. This tool is applied to the field of vehicle underframe maintenance technology. To enhance traction stability, buckles 8 are provided on both sides of the traction plate 5. The buckles 8 are made of spring steel and formed by a stamping process. After the traction rope passes through the traction hole 6, both ends are respectively engaged with the buckles 8 on both sides. The buckles 8 lock the traction rope with elastic force to prevent it from loosening during movement.
