Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 as shown,

[0015] A kind of tunnel inspection car, comprising vehicle frame, lateral positioning wheel group 3, described vehicle frame comprises a plurality of rail car units 1, and described a plurality of rail car units 1 are connected in a beaded shape, and on the plurality of rail car units 1 The insulated wheel 2 is integrated with a grating encoder. It is characterized in that the lateral positioning wheel set 3 is only installed on one track, and the number of sets of the lateral positioning wheel 3 installed on a rail car unit 1 is 2 groups. The positioning wheel set 3 is composed of 2 single wheels, and the 2 single wheels are respectively located on both sides of a track. The single wheel is in rolling contact with the side of the track, and the axis of the single wheel is perpendicular to the track plane, ensuring that th...

Abstract

The invention belongs to a low-speed rail vehicle and particularly relates to a tunnel detecting vehicle carrying a precise positioning detecting device. The tunnel detecting vehicle comprises a vehicle frame and transverse positioning wheel sets. The vehicle frame comprises a plurality of rail vehicle units. The transverse positioning wheel sets are only mounted on a rail, and the two transverse positioning wheel sets are mounted on each rail vehicle unit. Each transverse positioning wheel set is composed of two single wheels. According to the tunnel detecting vehicle, the structure is simple, batch production is facilitated, and the problem of a detecting image error caused by snaking travelling of the tunnel detecting vehicle is solved. Meanwhile, the tunnel detecting vehicle is low in manufacturing cost, energy consumption and fault rate.

Description

technical field [0001] The invention belongs to a low-speed rail car, in particular to a tunnel inspection car equipped with a precision positioning detection device. Background technique [0002] The trajectories of various types of railcars currently used in railway inspections are snake trajectories when running on the track. Therefore, in the detection occasions that require high positional accuracy, it is usually measured while stopping on the track and in a static state. After the rail car moves or moves, the rail car moves along a random snaking trajectory and then moves randomly laterally. Many measurement and detection methods based on precise positions 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 object of the present invention is to provide a tunnel inspection vehicle capable of precise lateral positioning, which overcomes the defect...
