[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts, any modifications, equivalent replacements, improvements, etc., shall be included in the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment discloses a tunnel clearance review and inspection vehicle, comprising a vehicle frame 1, with rollers 3 provided on both sides of the bottom end of the vehicle frame 1 and moving on rails 5 via the rollers 3;

[0020] The frame 1 includes a mounting part 101, which has a rectangular frame structure. Support rods 102 are fixedly connected to the inner sides of both ends of the mounting part 101 in the longitudinal direction, and mounting areas 103 for mounting rollers 3 are formed between the two ends of the mounting part 101 in the longitudinal direction and the corresponding support rods 102; two rollers 3 are arranged in sequence in the mounting area 103 along the width direction of the mounting part 101, and the rollers 3 in the two mounting areas 103 are arranged correspondingly; the rollers 3 are rotatably connected to the inner wall of one end of the mounting part 101 in the longitudinal direction and the side wall of the support rod 102 through a transmission shaft 302, and the axial direction of the transmission shaft 302 is consistent with the longitudinal direction of the mounting part 101.

[0021] A limiting convex ring 301 is integrally formed on the outer periphery of one end of the roller 3 close to the support rod 102; when the bottom ends of the two rollers 3 are in contact with the two rails 5 respectively, the limiting convex ring 301 is located on the inner side of the two rails 5 and limits the relative position between the roller 3 and the rail 5.

[0022] The rollers in the two installation areas are in contact with the two rails respectively, and the limiting convex rings on the rollers are located on the inner sides of the two rails, which limit the movement of the frame toward the outside of the rails, so that the frame will not fall off the rails when moving with the rollers, thereby ensuring the smooth progress of the rail review and inspection operation.

[0023] A crossbar 104 is fixedly connected to the center of the inner wall at both ends of the mounting member 101 in the width direction, and the length direction of the crossbar 104 is consistent with the length direction of the support rod 102.

[0024] The top of one end of the mounting member 101 in the width direction is fixedly connected to a hand push frame 4, the bottom end of the hand push frame 4 is fixedly connected to the mounting member 101, and the top end of the hand push frame 4 is tilted toward the side away from the center rod 201 to facilitate people to push the frame and the support frame to perform mobile detection operations.

[0025] The top of the frame 1 is fixedly connected to a support frame 2; the support frame 2 includes a center rod 201, a first detection rod 202, a second detection rod 203, and a reinforcement rod 204. The center rod 201 is located at the center of the frame 1, and the bottom end of the center rod 201 is fixedly connected to the center position of the cross bar 104. The middle of the center rod 201 is fixedly connected to the horizontally arranged first detection rod 202, and the top of the center rod 201 is fixedly connected to the horizontally arranged second detection rod 203. The length direction of the first detection rod 202 and the second detection rod 203 is consistent with the axial direction of the roller 3 (that is, perpendicular to the rail 5), and the center positions of the first detection rod 202 and the second detection rod 203 are fixedly connected to the center rod 201; both ends of the first detection rod 202 and the second detection rod 203 in the length direction extend to the outside of the two ends of the frame 1.

[0026] The first detection rod 202 and the second detection rod 203 are set to be of equal length and parallel to each other; the distance between the ends of the first detection rod 202 and the second detection rod 203 in the length direction and the center rod 201 is 2440 mm; the height distance between the first detection rod 202 and the frame 1 is 1210 mm, and the height distance between the second detection rod 203 and the frame 1 is 3000 mm.

[0027] During the re-verification inspection, setting the first inspection rod and the second inspection rod at heights of 1210mm and 3000mm can ensure that the distance between the middle and top positions of the train and the inner wall of the tunnel meets the inspection standards. These two positions are also the widest positions of the train. When these two positions meet the standards, other positions will definitely meet the standards. At the same time, the basic construction limit of the tunnel is 2440mm wide on both sides of the center of the line. As long as the first inspection rod and the second inspection rod can pass smoothly during the mobile inspection process, it ensures that the position of the rails meets the requirements and ensures the accuracy of the re-verification inspection.

[0028] There are two reinforcement rods 204, which are arranged side by side with the center rod 201 and the length direction of the reinforcement rods 204 is consistent with the length direction of the center rod 201; the bottom ends of the two reinforcement rods 204 are respectively fixed at the center positions of the two ends of the length direction of the mounting part 101, and the middle and top ends of the reinforcement rods 204 are respectively fixedly connected to the first detection rod 202 and the second detection rod 203.

[0029] The first detection rod and the second detection rod can be supported by the reinforcement rod to enhance the structural strength of the support frame and improve the supporting effect of the first detection rod and the second detection rod.

[0030] In the support frame structure of the present technical solution, the central rod, the reinforcement rod, the first detection rod, and the second detection rod are all detachable assembly structures, which can be disassembled and stored after use, saving storage space.

[0031] When the utility model conducts rail recheck inspection, it is only necessary to push the frame to move along the rail, and the operator only needs to check whether the first detection rod and the second detection rod on the center rod will collide with the inner wall of the tunnel; when the two ends of the first detection rod and the second detection rod do not collide with the inner wall of the tunnel, the distance between the rail and the inner wall of the tunnel meets the standard; when the two ends of the first detection rod and the second detection rod collide with the inner wall of the tunnel, the distance between the rail and the inner wall of the tunnel does not meet the standard, and the position of the rail needs to be reset; the entire recheck inspection process is simple and fast, and the operator does not need to perform distance comparison operations all the time, and the operation process saves time and effort; and the device does not require the use of a distance sensor, its cost is low, and at the same time, the situation of inaccurate detection results will not occur due to factors such as distance sensor failure and light influence, thereby ensuring that the operation quality of the rail recheck inspection operation is not affected, thereby bringing convenience to the rail recheck inspection operation.
