Description
Technical Field
The utility model belongs to the technical field of vehicle braking system part check out test set, especially, relate to experimental auxiliary rod of railway freight car bicycle and test device.
Background
The single-car test is an important means for testing the overhaul quality of each-stage repair-stroke brake part of a railway wagon, and is a main way for measuring the performance quality of wagon air brakes, brake regulators, automatic empty and heavy car adjusting devices and the like. The railway freight cars with the ST1-600 type brake adjusters are gradually eliminated, the railway freight cars with the ST2-250 type brake adjusters account for more than 90% of the freight car holding capacity, and a centralized control single-car test system is adopted in a single-car test during car repair. According to the section repair regulations of the railway freight cars, the single-car test of the railway freight cars is divided into two stages, namely a front stage of the car falling and a rear stage of the car falling, and the main test contents in the first stage comprise a main pipe leakage test, a whole car leakage test and a sensitivity test; the second stage includes stability test, performance test of the empty and heavy vehicle regulating valve, performance test of the brake regulator, etc.
This test method has the following problems:
1. secondary failures can occur: the sensitivity test before falling can cause the damage to the piston push rod of the brake cylinder, and the main reason is that the basic brake device of the existing vehicle is not connected with the basic brake device of the bogie, the push rod of the brake cylinder has no stroke limit measure, and when the sensitivity test is relieved in braking, the push rod of the brake cylinder can be completely pushed out, so that the damage to the reset spring of the push rod of the brake cylinder is easily caused, and the phenomenon of insufficient free height or even spring breakage occurs.
2. The single-vehicle test operation has the following cross: before the vehicle falls, only leakage of the main pipe and leakage of the whole vehicle are tested, and leakage detection and test cannot be carried out on the branch pipe and brake cylinder connecting pipe system during the brake test; the stroke of the piston of the brake cylinder can be judged only in the second stage, and when the stroke of the brake cylinder does not accord with the specification, the control lever of the brake adjuster needs to be cut off for adjustment; the state of the brake adjuster can be only carried out in the second stage, and the brake adjuster needs to be replaced when the state of the brake adjuster is found to be poor.
3. The second stage braking test is time-consuming and labor-consuming in the process of finding the braking fault: if the brake adjuster performance test is carried out after the vehicle falls, the brake adjuster is inconvenient to replace after the fault is found, and particularly, the vehicle bottom space of a flat vehicle and a flat collective shared vehicle is narrow, and the brake adjuster needs to be erected and matched again when replaced; after the automobile falls off, a braking stability test is carried out, the stroke of a brake cylinder needs to be adjusted by adjusting a brake adjuster control lever, electric welding operation exists, and the operation space is narrow.
4. The distribution of the test operation time of the single vehicle is unreasonable: the operation process of the single vehicle test is completely controlled by a centralized control single vehicle test system, the operation time is relatively fixed, the first stage test time is 60 minutes, the time interval from vehicle erecting to vehicle falling is 180 minutes, a neutral period of about 120 minutes exists in the phase, the second stage test time after the vehicle falling under the fault-free condition is 50 minutes, the time from vehicle falling to vehicle transferring and leaving from a warehouse is only 60 minutes, once the braking fault is met, the time is very short, the situation exceeding the vehicle repairing plan is often generated, and the cashing of the whole production plan is influenced.
