Description
Technical Field
[0001] The utility model belongs to the technical field of rail transit, and particularly relates to a width and height testing device for subway vehicles. Background Art
[0002] After the subway tunnel and track are built, it is necessary to test the operation conditions of the subway. For example, it is necessary to repeatedly detect and compare the external contour of the subway and the internal boundary of the tunnel, and change the internal contour of the tunnel or the length of the equipment installed on the inner wall of the tunnel extending into the tunnel according to the test results, so that the vehicle can pass through the tunnel smoothly, and no part of the tunnel and no equipment installed on the inner wall of the tunnel can touch any part of the vehicle, so that the vehicle can pass through the tunnel smoothly.
[0003] At present, subway tunnel clearance detection technologies generally adopt contact measurement, non-contact measurement, infrared measurement, etc. Among them, contact measurement is mainly to install a measurement device consistent with the clearance contour on the external hanging flat plate of the vehicle, and verify whether there is an encroachment of equipment and facilities by touching the contour baffle.
[0004] The prior art has the following deficiencies:
[0005] A measurement device only has one contour baffle, that is, it can only detect one type of vehicle, and the adaptability is low. Content of the Utility Model
[0006] In view of this, the utility model provides a width and height testing device for subway vehicles to solve the problem in the prior art that a vehicle clearance measurement device only has one contour baffle, that is, it can only detect one type of vehicle, and the adaptability is low.
[0007] The technical solution adopted by the utility model is as follows:
[0008] A width and height testing device for subway vehicles includes a testing component and two groups of brackets located on both sides of the track. The testing component includes a contour plate. The two ends of the contour plate are respectively connected to the two brackets. A contour opening is provided through the middle of the contour plate, and the contour opening matches the contour of the cross-section of the vehicle; there are multiple contour plates, and the multiple contour plates are arranged at intervals along the length direction of the track. The shapes of the contour openings on each contour plate are different; the contour plate is divided into two sub-plates from the middle thereof. Hinge rods are respectively provided at the ends of the two sub-plates, and the hinge rods are hinged to the brackets through rotating shafts, and the rotating shafts are arranged vertically.
[0009] In this technical solution, it should be noted that two groups of brackets are symmetrically arranged on both sides of the track. The track is used for the movement of vehicles. Each contour opening on each contour plate corresponds to a certain type of train. When it is necessary to verify whether there is a risk of equipment and facilities intrusion by a train, first, determine the contour plate that matches the contour of the train to be tested, and rotate and splice the two sub-plates of the contour plate respectively so that the two sub-plates are perpendicular to the brackets, making the contour plate form a complete contour opening. Then, rotate the sub-plates of the remaining contour plates to a position parallel to the brackets to prevent them from interfering with the experiment. Finally, start the experimental train and make the train travel on the track in the direction of the contour opening. During the process of the train passing through the contour opening, the staff observes whether there is contact between the train and the contour plate. If not, it means the train is qualified; if there is a collision, it means the train is unqualified. To sum up, in this utility model, due to the provision of contour plates of multiple types, this device can perform dimensional inspection on trains of different types, improving the adaptability of this device. In addition, this device divides each contour plate into two sub-plates, enabling each contour plate to be stored when not in use, preventing interference with the experiments of other types of trains.
[0010] Preferably, a fixing ring is provided on the bracket, a window hook is movably connected to the fixing ring, and a locking ring cooperating with the window hook is provided on the articulated rod.

[0012] Preferably, the sub-plate is divided into several plate bodies, and each plate body is respectively hinged to the bracket.
[0013] In this technical solution, it should be noted that a window hook structure is provided on each plate body, and each plate body is respectively rotatably connected to the bracket. In this solution, the sub-plate is further divided into multiple plate bodies. Such a setting can, after a plate body is damaged, replace only the plate body with the damaged part alone without replacing the entire sub-plate.
[0014] Preferably, a pedal is provided on the side of the bracket away from the track, and the pedal is located above the contour plate.
[0015] In this technical solution, it should be noted that the staff can perform maintenance on higher positions of the bracket or the contour plate by standing on the pedal.
[0016] Preferably, a ladder is provided at one end of the bottom of the pedal, and the bottom of the ladder is in contact with the ground.
[0017] In this technical solution, it should be noted that the provided ladder facilitates the staff to climb onto the pedal.

[0020] Preferably, protective fences are respectively provided on both sides of the pedal.
[0021] In this technical solution, it should be noted that the provided protective fences prevent the staff from falling when working on the pedal.

A contour opening 8 is provided through the middle of the contour plate 3, and the contour opening 8 matches the contour of the cross-section of the vehicle. There are multiple contour plates 3, and the multiple contour plates 3 are arranged at intervals along the length direction of the track 1.

The contour opening 8 on each contour plate 3 corresponds to a train of a certain model. When it is necessary to verify whether there is a risk of equipment and facilities intrusion by a train, first determine the contour plate 3 that matches the contour of the train to be tested, and rotate and join the two sub-plates 9 of the contour plate 3 respectively to make the two sub-plates 9 perpendicular to the brackets 2, so that the contour plate 3 forms a complete contour opening 8. Then, rotate the sub-plates 9 of the remaining contour plates 3 to a position parallel to the brackets 2 to prevent interference with the experiment. Finally, start the experimental train and make the train travel on the track 1 in the direction of the contour opening 8. During the process of the train passing through the contour opening 8, the staff observes whether there is contact between the train and the contour plate 3. If not, it means the train is qualified. If there is a collision, it means the train is unqualified. To sum up, in the utility model, due to the provision of multiple models of contour plates 3, the device can perform size detection on trains of different models, improving the adaptability of the device. In addition, the device divides each contour plate 3 into two sub-plates 9, so that each contour plate 3 can be stored when not in use, preventing interference with the experiments of other model trains.

Finally, start the experimental train so that the train travels on the track 1 in the direction of the profile opening 8. During the process of the train passing through the profile opening 8, the staff observes whether there is contact between the train and the profile plate 3. If not, it means the train is qualified; if there is a collision, it means the train is unqualified.
