Embodiment Construction
[0035] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0036] Because in the actual working process, the railway bridge inspection vehicle always walks along the steel rails, so the supporting legs of the railway bridge inspection vehicle can only be supported on both sides of the steel rails. Among them, when the railway bridge inspection vehicle is fixed by means of supporting legs, the s...

The embodiment of the invention discloses a railway bridge inspection vehicle supporting leg and a control method thereof. The railway bridge inspection vehicle supporting leg comprises a supporting leg body and a first supporting part coaxial with the supporting leg body. One end of the first supporting part is connected with the supporting leg body through a first supporting part driving unit, and the other end of the first supporting part is a sharp end. The first supporting part is provided with a second supporting part assembly comprising a second supporting part and a second supporting part driving unit, the second supporting part is provided with a first groove matched with the sharp end, and the second supporting part driving unit is used for driving the second supporting part to be buckled to or break away from the first supporting part. According to the supporting leg provided by the embodiment, the two supporting parts are designed for the working conditions of ballast tracks and ballastless tracks separately, the first supporting part or the second support part can be selectively used for supporting the two sides of a steel rail according to the practical working conditions in the working process, and the supporting leg can be applied to various working conditions.
Description
technical field [0001] The invention relates to the technical field of railway bridge inspection vehicles, in particular to a railway bridge inspection vehicle support leg and a control method thereof. Background technique [0002] Bridges are an important part of railway traffic, creating good conditions for the development of railways in harsh natural environments, but the aging of bridges or defects in design and construction will have a certain impact on traffic safety. In order to ensure the safety and reliability of bridges in long-term use, it is particularly important to carry out regular inspection and maintenance. In order to improve the maintenance efficiency of bridges in railways, railway bridge inspection vehicles are usually used to carry out maintenance on bridges. [0003] Figure 1A and Figure 1B It is a schematic diagram of the maintenance scene of a railway bridge vehicle inspection in the prior art, such as Figure 1A and 1B As shown, the railway bri...
