Description
Technical Field
[0001] The present invention relates to the field of rail transit, and more specifically, to a track detection and maintenance device for rail transit. Background Art
[0002] The full name of railroad track is railway track, which is a kind of railway facility. The track is usually composed of two balanced steel rails, which are fixed on sleepers, and ballast is under the sleepers. During the use of the rails, they need to be regularly diagnosed and maintained to ensure the safety of the rails. Therefore, rail fault diagnosis and maintenance equipment is needed to reduce safety hazards.
[0003] The existing track inspection and maintenance mainly grinds the surface of the rails and cleans the impurities on the surface of the rails to avoid affecting the subsequent use. If the rails are deformed, they need to be replaced in time. However, during the rail grinding process, manual grinding equipment is required to grind and maintain the top and side surfaces of the rails in turn, which is extremely inefficient and time-consuming. The existing grinding devices usually use two sets of grinding wheels for the top and side surfaces. For example, CN218880464U in the existing patent technology discloses a multifunctional grinding machine for railway maintenance, including a frame, a fixed frame and a walking mechanism, and the grinding mechanism adopts a U-shaped design; the frame also includes a motor, the motor is arranged inside the fixed frame, and the bottom end of the output shaft of the motor is connected to a grinding sheet through a coupling. The multifunctional grinding machine for railway maintenance can adapt to different railway tracks and can perform grinding to different degrees, and can well complete the maintenance of railway tracks. This equipment can grind the top and side of the rails at the same time;
[0004] However, although the above solution can achieve simultaneous touching and grinding of the top and sides of the rail body, if the heights of the rail bodies on both sides are different, for example, there is a different degree of settlement of the sleepers at the bottom, the grinding on both sides cannot be carried out automatically and the tilt detection cannot be realized. It is also necessary to set up a special tilt angle sensor and use a special cleaning device to clean and push the stone particles. Summary of the invention
[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a track inspection and maintenance equipment for rail transit. By setting a grinding assembly, the height of the grinding assembly can be adjusted by the top cylinder, so that the first grinding wheel can have better contact with the top surface of the rail.

[0040] Furthermore, first slide grooves 26 are provided on the outer surfaces of both sides of the side frame 23, and sliders 28 matching the first slide grooves 26 are fixedly installed on both sides of the inner wall of the grinding frame 2, and a guide rod 27 is fixedly installed inside the first slide groove 26, and the slider 28 is sleeved on the outer surface of the guide rod 27, and the outer surface of the guide rod 27 is located on one side of the slider 28 and is sleeved with a first return spring 29. In the process of pushing downward, the side frame 23 slides outward along the grinding frame 2, and when a sufficient distance is pulled away, the slider 28 will slide along the guide rod 27 to squeeze the first return spring 29.
[0041] The specific implementation method is as follows: when working, the equipment is moved to the rail that needs to be inspected and maintained, and the roller 11 at the bottom is rolled along the rail. At the same time, the cylinder on the main frame 1 is started to push the grinding frame 2 at the bottom downward until the first grinding wheel 21 in the grinding frame 2 contacts the top surface of the rail, and at the same time, the second grinding wheel 24 in the side frames 23 on both sides of the bottom of the grinding frame 2 contacts the side of the rail. In the process of pushing downward, the side frames 23 slide outward along the grinding frame 2 and pull away a sufficient distance.

The degree of inclination of the mark plate 3 can be understood through the finger plate 34, which is more convenient.
[0044] A rotary encoder is installed in one of the two finger plates 34, and the rotation amplitude and rotation direction are determined based on the value of the rotary encoder. The starting rotation direction of the third motor 43 is controlled in response to the rotation direction, and the third motor works in the first mode and the second mode. In the first mode, the duration ratio of the first mode and the second mode is controlled in response to the rotation amplitude. The first mode is to determine the position of the side with a higher height according to the tilt direction, and then the rotation direction of the third motor is selected so that the storage rack 5 moves toward the side with a higher height, and after moving to the end, a plurality of rake teeth 56 are pulled out, and then the third motor is controlled to move to the lower side, and the rake teeth 56 are retracted, and then the third motor 43 rotates in the opposite direction to the higher side, and the above-mentioned actions are continued to be circulated to perform a rough one-way sweep of the stones, and after executing several cycles, the second mode is entered, and in the second mode, the rake teeth 56 are kept pulled out in a natural hanging state and the third motor periodically switches the rotation direction, driving the rake teeth 56 to reciprocate, and the stones are finely swept left and right.
