Description

Technical Field

[0001] This utility model relates to the field of urban rail technology, and in particular to a device for removing foreign objects from urban rail tracks. Background Technology

[0002] As a vital component of modern urban public transportation, the safe and efficient operation of urban rail transit is of paramount importance. Foreign objects on the rails, such as gravel, fallen leaves, and garbage, can seriously affect train operation safety, potentially leading to accelerated wheel and rail wear, reduced braking performance, and even major accidents such as derailment.

[0003] Currently, traditional methods for removing foreign objects from rails mostly rely on manual inspection and cleaning. This method is inefficient and cannot meet the needs of high-density train operation, which has a certain adverse impact on the process of removing foreign objects from urban rails. In order to overcome the shortcomings of existing technologies, we propose an urban rail foreign object removal device. Utility Model Content

[0004] The main purpose of this utility model is to provide a foreign object removal device for urban rail tracks, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A foreign object removal device for urban rail transit includes a mobile vehicle. Connecting arms are provided on both side walls of the mobile vehicle. A sweeper is installed at the end of each of the two sets of connecting arms. A sliding rail is provided on the lower outer wall of the front end of each of the two sets of sweepers. A sliding block is provided in the middle of each of the two sets of sliding rails. A lead screw is installed in the middle of each sliding block. A first motor is installed inside the sweeper above the sliding rail and is connected to the end of the lead screw. A connecting rod is provided at the front end of the sliding block, and a cleaning brush is provided at the lower end of the connecting rod. The front end of the sweeper is located on the sliding rail. A set of mounting plates is provided on both sides of the sweeper. A rotating block is provided between the side walls of the two sets of mounting plates. A scraper is provided at the front end of the rotating block. A second motor is provided on the outer wall of one of the mounting plates. The second motor is connected to one end of the rotating block. A dust collection box is provided at the rear of the sweeper. A filter screen is provided at the top of the dust collection box. An air suction machine is provided above the filter screen at the upper part of the sweeper. An air inlet is provided at the front end of the dust collection box. Suction pipes are provided on both sides of the front end of the sweeper. The rear ends of the two sets of suction pipes are connected to the air inlet inside the sweeper.

[0007] Preferably, the lower end of the cleaning brush is fixedly connected with bristles, the two sides of the cleaning brush are symmetrically bent backward about the middle axis, and the sliding block is slidably connected to the sliding track.

[0008] Preferably, a rotating interface is provided between the lead screw and the inner wall of the sliding track, and the lead screw is rotatably connected to the inner wall of the sliding track through the rotating interface. A threaded hole is provided in the middle of the sliding block, and the lead screw passes through the middle of the sliding block and is threadedly connected to the sliding block.

[0009] Preferably, a rotating interface is provided between the two ends of the rotating block and the inner walls of the two sets of mounting plates, and the two ends of the rotating block are rotatably connected to the inner walls of the two sets of mounting plates through the provided rotating interface, and the scraper is tilted downward and positioned in front of the cleaning brush.

[0010] Preferably, the two sets of suction pipes are tilted downwards and positioned above the cleaning brush on both sides.

[0011] Preferably, the mobile vehicle has two sets of wheels on each of its lower sides, and a drive motor is installed inside the mobile vehicle. The inner sides of the four sets of wheels are connected to the drive motor installed inside the mobile vehicle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the two sets of scrapers can extend into the interior of the urban rail to scrape away foreign objects inside the rail. The two sets of cleaning brushes can sweep away the scraped foreign objects. The two sides of the cleaning brushes are bent backward to prevent the garbage from being swept back into the interior of the rail. The suction fan, dust collection box and dust collection container can suck up the scraped foreign objects and collect them into the dust collection box, making the device more effective and efficient in handling foreign objects on urban rail. It also saves labor.

[0014] 2. In this utility model, the sliding track and sliding block can adjust the height of the cleaning brush. When encountering some sloping road surfaces, the No. 1 motor can drive the sliding block to move up and down inside the sliding track through the lead screw to adjust the height of the cleaning brush and adapt to the changes in road surface slope. The rotating block can rotate between the side walls of the two sets of mounting plates, allowing the rotating block to adjust the angle of the scraper, so that the device can adapt to the slope of different tracks and achieve better cleaning effect on the tracks.

The first motor 14 is used to drive the lead screw 13 to rotate, and the sliding block 11 will move on the outer wall of the lead screw 13 and move up and down in the middle of the sliding track 10. A connecting rod 12 is provided at the front end of the sliding block 11, and a cleaning brush 6 is provided at the lower end of the connecting rod 12. The connecting rod 12 is used to connect the cleaning brush 6 to the sliding block 11. The sliding rail 10 and the sliding block 11 can adjust the height of the cleaning brush 6. The lower end of the cleaning brush 6 is provided with bristles. The cleaning brush 6 has a central axis and bends backward on both sides to clean foreign objects removed from the rail. The bending shape also prevents foreign objects from falling back into the rail. The front end of the sweeper 4 is provided with a set of mounting plates 9 on both sides of the sliding rail 10. A rotating block 15 is provided between the side walls of the two sets of mounting plates 9. The two ends of the rotating block 15 are connected to the two sets of mounting plates.
