Auxiliary guide device and rail inspection equipment

Abstract

The invention provides an auxiliary guide device which is applied to a track inspection trolley, the track inspection trolley comprises a trolley body fixing assembly and an auxiliary stub wing device, the auxiliary guide device and the auxiliary stub wing device are independently arranged, the auxiliary guide device comprises an auxiliary guide wheel body and a mounting part, and the mounting part is connected with the trolley body fixing assembly through a fixing piece. The auxiliary guide wheel body is installed on the mounting part and can rotate relative to the mounting part. According to the auxiliary guide device provided by the invention, by mounting the auxiliary wheel body, when the track inspection trolley passes through the harmful space of a turnout, the auxiliary wheel body rolls in a manner of being attached to the side wall of the guard rail, the deflection degree of the trolley body is limited, the front end of the auxiliary stub wing can conveniently pass through the harmful space, and the track inspection trolley can smoothly pass through the harmful space of the turnout by utilizing a simple structure; the obstacle crossing ability is enhanced, and human interference is not needed; meanwhile, equipment damage and even safety accidents caused by falling into harmful space of the turnout are avoided.

Description

technical field [0001] The invention relates to the technical field of track inspection, in particular to an auxiliary guiding device and track inspection equipment. Background technique [0002] The full name of the track inspection trolley is the track geometric state monitor. It is a testing instrument commonly used to ensure that the track parameters are in the correct state. It is mainly used for high-speed railways, trams, subways, and ballasted railways with high design speeds. [0003] Existing track inspection trolleys usually rely on the built-in gauge tension springs of the body beams to ensure that the guide wheels on both sides are in close contact with the inner working sides of the rails, so as to ensure that the running wheels do not deviate from the track. When passing through the harmful space of the track switch, Because the gauge at the center rail end is widened, the guide wheels on both sides are opened to cause the vehicle body to deflect to the harmfu...

Problems solved by technology

[0004] Based on this, the object of the present invention is to provide an auxiliary guide device and track inspection equipment to solve the problem that the running wheels on the track inspection trolley in the prior art are easily trapped in the harmful space of the turnout and cannot be retracted by themselves, causing the track inspection trolley to fall into the harmful space of the turnout.
