Description

Technical Field

[0001] The utility model belongs to the technical field of track detection, and in particular relates to a portable track pavement detection device. Background Art

[0002] Track gauge is a basic geometric parameter of railway lines. Its quality is directly related to the safe operation of railway trains. Railway track gauge is an important railway-specific measuring instrument that provides direct technical basis for line maintenance and construction. It is mainly used for static measurement of these geometric parameters. It also has the function of measuring the inspection interval and back guard distance of turnouts.

[0003] In the past, the track gauge was used to detect the track gauge at intervals. In this way, the track gauge needed to be placed at the track measuring section. After the measurement was completed, it was picked up again and moved to the next measuring position to repeat the measurement operation. The frequent bending and standing up of the inspection staff was a heavy burden. Nowadays, rollers are generally installed at the bottom of the track gauge, and a pushing handle is provided on the upper part to push the track gauge when people walk. However, when the roller rolls directly on the upper part of the track, the direction is not easy to control, and the person's force and tilting can easily cause the roller to fall off the track. In addition, the pushing handles set in the upper and lower directions on the top of the track gauge increase the occupied space, and the protruding pushing handle brings inconvenience to the subsequent transfer and transportation.

[0004] Therefore, a portable track pavement detection device is needed to solve the problem in the prior art that the track gauge with rollers installed at the bottom directly moves along the track, which may cause derailment during operation and the push handle on the top makes it inconvenient to transfer and carry.
