Abstract

The invention relates to a centering adjustment method for wheel sets of a locomotive test stand and a traction force meter stand thereof. In order to enable all locomotive wheels of a locomotive to completely fall into corresponding rail wheels in foundation pits of the test stand, during test, the centers of the locomotive wheels are required to be kept perpendicularly centered with the centers of the rail wheels, and the locomotive is required to run in location mode in the horizontal direction, and thus the tested locomotive can be ensured to run stably and safely on the test stand. The centering adjustment method of the test stand of the locomotive comprises the following steps of 1 selecting the central lines of the foundation pits of the rail wheels to serve as location reference lines; 2 adopting a double-traction force meter stand to serve as the test stand; 3 performing secondary centering adjustment on the locomotive wheel sets and the rail wheel sets; and 4 providing the same pre-tightening force for a car coupler of the tested locomotive, and offsetting or reducing the horizontal displacement of the locomotive caused by deformation of the car coupler buffer. A speed reducer shaft of the traction force meter stand is parallel with a crew, a nut is screwed on the screw, a chain wheel on the speed reducer shaft is connected with a chain wheel on the nut through a chain, and one end of the screw is connected with a traction force measurement device.

Description

technical field

[0001] The invention relates to a wheel alignment adjustment method of a locomotive test bench and a traction force meter thereof. Background technique

[0002] The locomotive enters the test bench through the guide beam device, and the locomotive wheel is centered up and down with the pre-placed rail wheel in the foundation pit of the test bench. The locomotive coupler is hung on the coupler on the traction meter platform and positioned. run on an infinitely long track. In the test, due to the existence of the coupler buffer device of the tested locomotive and the existence of the gap between the couplers, the horizontal position of the tested locomotive changes with the traction force, and the front and rear serial shifts occur. As the locomotive accelerates or decelerates, the coupler frequently collides, which affects the operation of the locomotive. System stability, safety and traction force measurement accuracy.

Embodiment Construction

[0047] The present invention is further described now in conjunction with accompanying drawing.

[0048] image 3 It is a schematic diagram of the positioning of the retractable coupler with double traction gauges for the tested locomotive. According to the coupler center distance of the locomotive to be tested, the retractable coupler position of the A-end traction meter platform 17 is preset. The test locomotive 13 moves slowly, and its coupler is locked with the retractable coupler of the A-end traction meter platform 17, and the whole weight of the locomotive 13 is seated on the track wheel 15 through the locomotive wheel 14 through the lifting mechanism. If there is a gap between the coupler and the coupler, adjust it so that the coupler is under pressure, and the force display shows a negative value; return the traction force meter 16 at the B end, start the telescopic coupler, and lock it with the coupler of the locomotive under test. For the centering of the wheel pa...
