[0002] With the development of rail transit, the increase of operating mileage, the improvement of vehicle speed, line operation is increasingly busy. As the basis of rail transit operation, track diseases are increasing, and track is difficult to avoid various fault hidden dangers under long-time high-load operation, such as track installation size change, track surface wear and defect, ballast foreign matter, fastener anomaly, track irregularity and other hidden dangers. In order to ensure the long-term normal operation of track, track detection has become an important link in rail transport.

[0003] The existing track detection method generally adopts three kinds, namely manual detection, vehicle-mounted detection and track detection robot. Among them, manual detection can only use rail transit window time, and relies on professional personnel to go online and patrol line. This method can only use short detection time each time, has low efficiency, has high technical requirements for patrol personnel, and needs a large number of professional detection personnel to complete line detection, which has high labor cost. The vehicle-mounted detection vehicle is fast and has high detection efficiency, but the recognition rate is relatively low, and is limited by operating time and other conditions. After detecting the fault, manual on-site review of the fault is needed. The track detection robot is similar to the vehicle-mounted type, but most of the existing track detection robots have single function and can only detect one kind of defect. If other functions need to be detected, the corresponding vehicle needs to be replaced, which is very inconvenient. In addition, the early designed track detection robot is heavy and not conducive to carrying. UTILITY MODEL CONTENT

[0023] The front car body 10 and rear car body 20 all include frame 11, wheel 12, nitrogen spring 13 and adjusting support rod 14.Two groups of frame 11 are oppositely arranged left and right, a plurality of wheel 12 is respectively installed on the front and rear ends of frame 11, the upper and lower ends of nitrogen spring 13 are respectively connected with frame 11 and upper frame 40, and the nitrogen spring 13 can be elastically extended and contracted, and the two ends of adjusting support rod 14 are respectively connected with frame 11 and nitrogen spring 13, and the adjusting support rod 14 can be adjusted by extension and contraction.

[0024] The frame 11 of split type cooperates with the structure of nitrogen spring 13 and adjusting support rod 14, and the folding or unfolding function of the detection vehicle can be easily realized.When it runs on the track, it can be quickly folded to avoid other working vehicles when it encounters other working vehicles.In addition, the detection vehicle can also be folded to reduce the volume when it is moved near the track, so that it is more convenient for transportation and transfer.

[0025] The upper end of nitrogen spring 13 is further provided with a plurality of folding limiting blocks 15, and the bottom of upper frame 40 is further provided with a plurality of folding pull rods 41, folding springs (not shown in the figure) and folding pull handles 42.A plurality of folding limiting blocks 15 are provided with front and rear through limiting through holes (not shown in the figure), the limiting through holes are designed in the shape of "8", a plurality of folding pull rods 41 are sequentially arranged in the limiting through holes and the bottom of upper frame 40, a plurality of folding springs are arranged on the folding pull rods 41, and the folding pull handle 42 is arranged on one end of a plurality of folding pull rods 41.

[0026] When the nitrogen spring 13 is in the contracted state, the detection vehicle is also in the folded state, and at this time, the folded state of the detection vehicle is locked by the mutual limiting between the folding pull rod 41 and the folding limiting block 15.When the folding pull handle 42 is pulled, the folding pull rod 41 will reset from below to above the hole position of the limiting through hole, and at this time, the folding pull rod 41 and the folding limiting block 15 will be unlocked, and the elastic force of the nitrogen spring 13 will expand the front car body 10 and the rear car body 20 on both sides of the upper frame 40, so as to realize the automatic unfolding of the detection vehicle.The locking structure cooperates with the nitrogen spring 13 to make the trolley open conveniently, which can reduce human intervention, and the folding pull rod 41 can make the action flat when the car body is compressed or expanded, and limit the car body from shaking unevenly.
