Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] Please refer to figure 1 and figure 2 , The ground coupler positioning device of the locomotive test bench of the present invention includes: a foundation base platform 1, a machine base 2, a transmission system 3 and a movable coupler assembly 4. The main body of the foundation base platform 1 is buried underground, and its height is equal to the ground. The machine base 2 is installed on the foundation base platform 1. In this embodiment, the machine base 2 is fastened by fastening the bolt assembly 7, specifically by opening a T-shaped groove on the foundation base platform 1, and the T-shaped bolt and the nut cooperate with the T-shaped groove to fasten the The base 2 is installed on the foundation base platform 1 . The advantage of this method is: it is very convenient to install and...

Abstract

The invention discloses a device and system for positioning a locomotive testing bed ground draw gear. The device comprises a foundation base platform, a device base, a transmission system and a movable draw gear assembly. The device base is installed on the foundation base platform and comprises an device base track, the movable draw gear assembly comprises the draw gear, a tension sensor, a draw gear bracket and draw gear bracket rolling wheels, the rear end of the draw gear is connected with the tension sensor which is installed in the draw gear bracket, the draw gear bracket rolling wheels are installed on the draw gear bracket and installed on the device base track in a rolling mode, and the transmission system drives the movable draw gear assembly to move. According to the device for positioning the locomotive testing bed ground draw gear, the transmission system is adopted for driving the movable draw gear assembly to move on the device base track of the device base, the travel distance of the device is large, and requirements for accurate positioning for different vehicle types are met.

Description

technical field [0001] The invention relates to the technical field of locomotive testing, in particular to a ground coupler positioning device and system of a locomotive test bench. Background technique [0002] The newly produced locomotives must be tested to verify that their performance meets the requirements before leaving the factory. The commonly used test method for verifying the performance of a locomotive is to pull the tested locomotive onto a specially designed locomotive test bench, align the wheels of the tested locomotive with the companion test wheels of the test bench, and then let the wheels of the tested locomotive rotate to drive the test bench to accompany the wheel. The test wheel rotates to simulate the movement of the locomotive on the track. In this process, the location of the tested locomotive is very critical. At present, a coupler positioning device is used to pull the tested locomotive to achieve positioning, that is, the coupler of the couple...
