Technical Field

The invention relates to the technical field of rail transit detection, in particular to a compressing connection device and rail detection equipment.

Background

The power supply rail, also called a third rail, is a rail installed beside an urban rail line such as a subway, a light rail and the like and used for supplying power independently. The power supply rail is matched with the current collector, the collector shoe and the like to work, and provides power support for all equipment on the rail transit train. The contact between the rail transit train and the power supply rail is physical contact, and the rail transit train is in a high-speed running state; specifically, the current collector of the rail transit train contacts and slides on the power supply rail to transmit electric power to the train. However, high-voltage arcs are generated in the sliding process of the current collecting device, so that welding spots are formed on the rail surface of the power supply rail, and irregular scratches are generated at the same time, so that the rail surface of the power supply rail is abraded. These damages affect the working performance of the power supply rail and the power collecting device, so that in the routine maintenance process, the rail surface condition of the power supply rail needs to be detected by using rail detection equipment.

However, the existing power supply rail is not straight, and a common power supply rail is, for example, in a shape that the inlet section and the outlet section are in an inclined upward state, and a horizontal section between the inlet section and the outlet section is in a relatively horizontal state. When the conventional track detection equipment collects the track surface data information of the power supply track, the track surface data information cannot be adjusted in time according to the shape of the power supply track, so that the accuracy of the track surface data information of the power supply track is influenced.
