Problems solved by technology
[0003] In the prior art, there are two ways to detect the parking braking force of the rail vehicle. One is to directly measure the parking braking force of the rail vehicle through the test device, but for different types of rail vehicles, it is often necessary to replace the corresponding test device to complete the measurement. The efficiency is not high; the other is to measure the braking force of the rail train by parking the rail vehicle on the actual ramp for demonstration. The work efficiency of this method is not high, and the labor intensity of the personnel is very high

The invention provides a parking braking test device which comprises a supporting frame connected with a rail, wherein the supporting frame is provided with a bearing hook connected with a railway vehicle; the bearing hook is connected with a loading oil cylinder for applying a load; the loading oil cylinder is connected with a height adjustment screw rod for adjusting the vertical height of the bearing hook; the supporting frame is provided with a test control module for testing the load. By aiming at the railway vehicles with different vehicle hook heights, the parking braking test device provided by the invention can be used for adjusting the height of the bearing hook so as to adapt to the height of the vehicle hook, so that the application range to the railway vehicles is wider, a test process is simple and quick, the labor intensity is low, the time is shortened, and the working efficiency of a railway vehicle parking braking test is improved.
Description
technical field [0001] The invention relates to the technical field of braking force testing, and more particularly, to a parking brake testing device. Background technique [0002] The braking performance of rail vehicles is an important factor affecting safe driving, so it is also the focus of rail vehicle detection. One of the most basic criteria for judging the braking performance is the braking force. The braking of rail vehicles includes parking brakes, so in the process of checking the braking performance of rail vehicles, one of them is to check the parking brake performance of rail vehicles. [0003] In the prior art, the parking braking force of the rail vehicle is detected in two ways. One is to measure the parking braking force of the rail vehicle directly through the test device. However, for different types of rail vehicles, it is often necessary to replace the corresponding test device to complete the measurement. The efficiency is not high; the other is to ...
