Description
Technical Field
The invention relates to the technical field of testing of vehicle speed reducers of railway marshalling stations, in particular to an intelligent tester for measuring the shortest distance between openings of two brake rails.
Background
At present, for a railway freight marshalling station vehicle speed reducer (such as a hump station speed reducer) in China, a general measuring tool is generally adopted for measuring the minimum distance between two braking rails of the speed reducer, such as: and (4) an outer diameter caliper. Because the top surfaces of the two braking rails are irregular surfaces, when a universal measuring tool is used for testing, the standardization and the normalization of measurement cannot be realized, certain human factors exist, and the measurement error is larger.
In addition, the measurement of the minimum distance between the two brake rails of the vehicle retarder of the freight marshalling station has large workload and needs a large amount of manpower.
It should be noted that the minimum distance between the two brake rails of the speed reducer is measured because: in the case of a hump yard vehicle retarder, the reduction of the freight vehicle is mainly realized by the squeezing friction between two adjacent brake rails on the retarder and the wheels of the freight vehicle. After the speed reducer is used for a period of time, the opening distance between two adjacent brake rails changes (becomes larger), when a vehicle passes through the speed reducer, the braking force of the speed reducer on the vehicle also changes (becomes smaller), and in order to ensure the braking force of the speed reducer, the distance between the brake rails needs to be detected.
Referring to fig. 1, the two brake rails of the retarder include a first brake rail 1000 and a second brake rail 2000 which are oppositely distributed; below the gap between the first brake rail 1000 and the second brake rail 2000 is a stock rail 3000;
as can be seen from fig. 1, for the first brake rail 1000 and the second brake rail 2000, the rail heads of the two brake rails are arc surfaces, the first brake rail 1000 and the second brake rail 2000 are oppositely arranged, and the minimum distance t between the two brake rails refers to the minimum distance between the arc surfaces of the two brake rail heads. The wheels of the freight vehicle roll on the rail heads of the stock rails, and the reducer decelerates the vehicle by means of the squeezing friction between the two brake rails and the wheels, so that the detection of the minimum distance t between the two brake rails is important.

Referring to fig. 2a to 6, the invention provides an intelligent tester for measuring the shortest distance between two brake rail openings, which is used for measuring the shortest distance (namely the shortest distance) between two brake rails of a vehicle speed reducer of a railway freight hump marshalling station and comprises a spring telescopic mechanism;

wherein, the two first guide rails 3 are transversely distributed and are positioned at the longitudinal middle position of the bottom plate 1;
the first guide rail 3 is fixed on the top of the bottom plate 1 through a bolt;
the left end and the right end of the top of the first guide rail 3 are respectively provided with a first sliding block 4;
