[0036] see figure 1 , the present embodiment provides a railcar 10, which can avoid the serpentine movement of the railcar 10 when traveling, and ensure that the railcar 10 can be accurately positioned in a direction perpendicular to the forward direction.

[0037] see figure 2 , wherein the rail car 10 is used for rolling connection to the track (not shown). The rail car 10 includes a car body 100, wheels 200 and laterally positioned wheel sets 300, the wheels 200 are rollingly connected to the car body 100, and the wheels 200 are used for connecting with rails. The lateral positioning wheel set 300 is connected to the car body 100, and the lateral positioning wheel set 300 is used for rolling contact with the track, which can prevent the rail car 10 from serpentine movement when it is moving, and can ensure that the rail car 10 does not produce lateral deviations.

[0038] It should be noted that, in this embodiment, when the rail vehicle 10 is traveling on the track, th...

[0066] This implementation provides a tunnel inspection car (not shown), wherein the tunnel inspection car includes a grating encoder (not shown) and a plurality of railcars 10 provided in the first embodiment, and a plurality of railcars 10 beaded connection, the grating encoder is integrated on the wheel 200 . The tunnel inspection vehicle can avoid the serpentine movement of the tunnel inspection vehicle when it is moving, and ensure that the tunnel inspection vehicle can be accurately positioned in a direction perpendicular to the forward direction.

[0067] When the tunnel inspection vehicle is traveling in the tunnel, the image information in the tunnel is obtained through the detection device installed on the tunnel inspection vehicle. The precise distance traveled by the rail car 10 can be obtained by multiplying the circumference of the wheel 200 by the angle turned. The tread 220 of the wheel 200 used by the tunnel inspection vehicle provided by the present invention...

Abstract

A railway vehicle (10) and a tunnel detection vehicle: the railway vehicle (10) is configured so as to be rollingly connected to a railway and comprises a vehicle body (100) and wheels (200); the wheels (200) are connected to the vehicle body (100) and are configured so as to be rollingly connected to the railway. The railway vehicle (10) also comprises two horizontal positioning wheel sets (300), the horizontal positioning wheel sets (300) comprising positioning wheels (310) and return wheels (320); the positioning wheels (310) are configured so as to rollingly contact a same side of the railway, and the return wheels (320) are configured, relative to the positioning wheels (310), so as to rollingly contact the other side of the railway; the positioning wheels (310) are fixedly connected to the vehicle body (100), and the return wheels (320) are flexibly connected to the vehicle body (100); the minimum adjustable distance between the positioning wheels (310) and the return wheels (320) is shorter than the distance between the two horizontal opposite sides of the railway. A tunnel detection vehicle that employs said railway vehicle (10). The railway vehicle (10) and the tunnel detection vehicle may prevent a snaking movement from occurring during movement, ensuring that the railway vehicle (10) may be accurately positioned in the direction perpendicular to the forward direction.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a rail car and a tunnel inspection car. Background technique [0002] At present, the running trajectories of various types of rail cars used in the detection of rail transit buildings such as railways and subways are snake trajectories. Therefore, in the detection occasions that require high position accuracy, it is usually used to stop on the track and measure in a static state, and then move to the next measurement point. After the rail car moves or moves, the position of the rail car moves randomly laterally after it advances in a random snaking trajectory. Many precision position-based measurement and detection technologies need to re-measure the position of the rail car or detection equipment. This leads to a significant reduction in detection efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a rail car, which can avoid the ser...
