Full-automatic railway track detection vehicle capable of avoiding trains

Abstract

The invention discloses a full-automatic railway track detection vehicle capable of avoiding trains. The detection vehicle is composed of three parts, namely a frame, contractible wheel devices and a vehicle body lifting device, wherein each contractible wheel device is represented as a Pi-shaped component (Pi: ratio of circumference to diameter) formed by welding three stainless steel rectangular pipes in the form of two transverse pipes and one vertical pipe; two ends of the vertical rectangular pipes are connected with two power motors and track wheels by virtue of hinges and are provided with shock absorbers; the power motors are coaxially connected to the track wheels; the two transverse rectangular pipes are connected to the frame by virtue of chutes; push rod motors are connected between the contractible wheel devices and the frame; the contractible wheel devices are respectively connected to the left and right ends of the frame; the vehicle body lifting device is composed of rhombic jacks and a support frame; the upper part of each rhombic jack is connected to the frame and the lower part of each rhombic jack is connected to the support frame; the rhombic jacks are respectively arranged in the front and at the back of the frame; and the lower part of a lifting platform is connected to a vehicle body by virtue of a plurality of lifting rods. Since the track wheels are connected to the vehicle body by virtue of the contractible wheel devices and the chutes, the detection vehicle disclosed by the invention can change tread, reduce volume and can be hidden in the track, so as to avoid trains conveniently.

Description

technical field [0001] The invention belongs to the technical field of railway equipment, and relates to a railway track parameter measuring device. technical background [0002] The track inspection vehicle is an important technical equipment for checking track defects, guiding maintenance and repair operations, and ensuring driving safety. It is also an important part of realizing track computerized management. There are currently two types of track inspection vehicles, portable track inspection trolleys and large track inspection vehicles. The portable track inspection trolley is a light-duty track inspection device that can automatically detect the position of the line center line, the elevation of the rail top, the gauge, and the superelevation of the track according to the pre-input design line type. It is small and flexible, but it cannot walk independently. , the degree of automation is not high, and manual operation is required. The measuring trolley adopts fixed-p...
