Problems solved by technology
[0004] However, in the car body manufacturing process, the coupler buffer device assembled in the last link is often severely restricted due to the inevitable error and the cumulative effect of errors in the previous links, resulting in the coupler height after loading cannot meet the relevant regulations. Require
The existing method of manually adjusting the height of the coupler with the screw and thimble requires the cooperation of multiple people to operate, which is time-consuming and laborious, and has potential safety hazards

The invention discloses a railway vehicle coupler height adjustment device and an adjustment method. The adjustment device includes a mobile device, the mobile device is provided with a jack and a fixing piece for fixing the jack; the top of the jack is provided with a Lifting rod, the top of the lifting rod is detachably connected with an extension rod; the top of the extension rod is provided with a connecting groove for connecting with a vehicle coupler. The railway vehicle coupler height adjusting device of the present invention has a stable and reliable structure, is easy to move, convenient and fast to operate, and saves time and effort. When in use, the adjustment device can be easily moved to the bottom of the vehicle coupler by moving the device, and the connecting groove on the top of the extension rod is connected with the vehicle coupler, and the lifting rod and the extension rod are pushed up by the jack, thereby pushing the vehicle coupler up to realize the vehicle Adjustment of coupler height.
Description
technical field [0001] The invention relates to the technical field of railway vehicle maintenance equipment, in particular to a railway vehicle coupler height adjustment device and adjustment method. Background technique [0002] Coupler buffer device is a vehicle component used to connect vehicles, locomotives or motor vehicles to each other, transmit traction force, braking force and ease longitudinal impact force. [0003] In order to ensure the safety and reliability of the vehicle coupling and the interchangeability of the installation of the coupler buffer device, there are strict requirements on the height of the coupler buffer and the rail surface. According to relevant railway locomotive regulations in my country: After the coupler buffer is loaded, the height of the horizontal centerline of the coupler knuckle from the rail surface in the empty state is 880mm for passenger cars (+10mm, -5mm error is allowed), and for freight cars It is 880mm (±10mm). [0004] How...
