Further, the brake adjuster testing device further comprises a displacement detecting device for detecting the moving distance of the adjusting structure.
Further, a valve device is arranged on a communicating pipeline between the air storage cylinder and the brake cylinder.
By applying the technical scheme of the application, the limiting structure is arranged on the rack and is matched with the stop iron of the brake adjuster to be tested so as to limit the moving stroke of the brake adjuster to be tested. The first connecting seat is connected with the rear end of the brake adjuster to be tested and moves along with the brake adjuster to be tested. The adjusting structure is arranged on the rack in a position adjustable manner along the length direction of the rack. The first connecting seat is positioned between the first driving structure and the adjusting structure.
When the brake adjuster to be tested is tested, a tester firstly moves the adjusting structure to a certain position, and then drives the brake adjuster to be tested to move along the length direction of the rack through the first driving structure. According to the specific position of the adjusting structure, the test process of the brake adjuster test device is divided into the following three types:
in the moving process of the brake adjuster to be tested, the stop iron on the brake adjuster to be tested is gradually close to the limiting structure, and when the stop iron is matched with the limiting structure, the whole brake adjuster to be tested is not moved any more, and the first connecting seat is attached to the adjusting structure. At this time, the brake adjuster to be tested does not need to be automatically adjusted (the wheel shoe distance simulated between the first connecting seat and the adjusting structure is equal to the brake cylinder stroke simulated between the limit structure and the stop iron at the initial position);
in the moving process of the brake adjuster to be tested, the stop iron on the brake adjuster to be tested is gradually close to the limiting structure, and when the stop iron is matched with the limiting structure, the whole brake adjuster to be tested is not moved any more, and a distance is reserved between the first connecting seat and the adjusting structure. At this time, the brake adjuster to be tested automatically stretches, and finally the first connecting seat is adjusted to be attached to the adjusting structure (the simulated wheel shoe distance between the first connecting seat and the adjusting structure is larger than the simulated brake cylinder stroke between the limiting structure and the stop iron at the initial position);
in the moving process of the brake adjuster to be tested, the stop iron on the brake adjuster to be tested is gradually close to the limiting structure, and the first connecting seat is attached to the adjusting structure. At this time, the whole brake adjuster to be tested continues to move forwards, and meanwhile, the brake adjuster to be tested automatically shortens until the stop iron is matched with the limiting structure, and the whole brake adjuster to be tested does not move any more (the wheel shoe distance simulated between the first connecting seat and the adjusting structure is smaller than the brake cylinder stroke simulated between the limiting structure and the stop iron at the initial position).
Since the brake adjuster is mainly used for automatically adjusting when the gap between the vehicle wheel and the brake shoe changes, a constant wheel shoe gap (gap between the vehicle wheel and the brake shoe) and a constant brake cylinder stroke are ensured. The structure simulates the actual use environment of the brake adjuster, specifically, the first connecting seat simulates a brake shoe, the adjusting structure simulates a vehicle wheel, and the position of the adjusting structure can simulate the change of the gap between the vehicle wheel and the brake shoe. Therefore, the brake adjuster testing device can perform performance test on the brake adjuster, and the accuracy of the testing result is obviously improved.

As shown in fig. 1 to 3, the brake adjuster testing apparatus of the present embodiment includes a stand 10, a first driving structure, a limiting structure 30, a first connecting seat 40, and an adjusting structure 50. The first driving structure is connected with the front end of the brake adjuster 20 to be tested and drives the brake adjuster 20 to be tested to move along the length direction of the rack 10. The spacing structure 30 is disposed on the gantry 10. The limiting structure 30 cooperates with the stop iron 21 of the brake adjuster 20 to be tested to limit the moving stroke of the brake adjuster 20 to be tested. The first connecting seat 40 is connected with the rear end of the brake adjuster 20 to be tested and moves along with the brake adjuster 20 to be tested. The adjustment structure 50 is adjustably positioned on the gantry 10 along the length of the gantry 10. The first connecting seat 40 is located between the first driving structure and the adjusting structure 50.
With the brake adjuster testing device of the present embodiment, a limiting structure 30 is disposed on the stand 10, and the limiting structure 30 cooperates with the stop iron 21 of the brake adjuster 20 to be tested to limit the movement stroke of the brake adjuster 20 to be tested. The first connecting seat 40 is connected with the rear end of the brake adjuster 20 to be tested and moves along with the brake adjuster 20 to be tested. The adjustment structure 50 is adjustably positioned on the gantry 10 along the length of the gantry 10. The first connecting seat 40 is located between the first driving structure and the adjusting structure 50.
When the brake adjuster 20 to be tested is tested, a tester firstly moves the adjusting structure 50 to a certain position, and then drives the brake adjuster 20 to be tested to move along the length direction of the rack 10 through the first driving structure. According to the specific position of the adjusting structure 50, the test process of the brake adjuster test device is divided into the following three types:
in the moving process of the brake adjuster 20 to be tested, the stop iron 21 on the brake adjuster 20 to be tested is gradually close to the limiting structure 30, and when the stop iron 21 is matched with the limiting structure 30, the brake adjuster 20 to be tested is not moved as a whole, and the first connecting seat 40 is attached to the adjusting structure 50. At this time, the brake adjuster 20 to be tested does not need to be automatically adjusted (the wheel shoe distance simulated between the first connecting seat 40 and the adjusting structure 50 is equal to the brake cylinder stroke simulated between the limit structure 30 and the stop iron 21 at the initial position);
in the moving process of the brake adjuster 20 to be tested, the stop iron 21 on the brake adjuster 20 to be tested is gradually close to the limiting structure 30, and when the stop iron 21 is matched with the limiting structure 30, the brake adjuster 20 to be tested is not moved as a whole, and a certain distance is reserved between the first connecting seat 40 and the adjusting structure 50. At this time, the brake adjuster 20 to be tested automatically extends, and finally the first connecting seat 40 is adjusted to be attached to the adjusting structure 50 (the wheel shoe distance between the first connecting seat 40 and the adjusting structure 50 is greater than the brake cylinder stroke between the limit structure 30 and the stop iron 21 at the initial position);
in the moving process of the brake adjuster 20 to be tested, the stop iron 21 on the brake adjuster 20 to be tested is gradually close to the limiting structure 30, and the first connecting seat 40 is attached to the adjusting structure 50. At this time, the brake adjuster 20 to be tested is continuously moved forward, and at the same time, the brake adjuster 20 to be tested is automatically shortened until the stop iron 21 is matched with the limit structure 30, and the brake adjuster 20 to be tested is not moved any more (the wheel shoe distance simulated between the first connecting seat 40 and the adjusting structure 50 is smaller than the brake cylinder stroke simulated between the limit structure 30 and the stop iron 21 at the initial position).
Since the brake adjuster is mainly used for automatically adjusting when the gap between the vehicle wheel and the brake shoe changes, a constant wheel shoe gap (gap between the vehicle wheel and the brake shoe) and a constant brake cylinder stroke are ensured. The above structure simulates the actual use environment of the brake adjuster, specifically, the first connecting seat 40 simulates the brake shoe, the adjusting structure 50 simulates the vehicle wheel, and the position of the adjusting structure 50 can simulate the gap between the vehicle wheel and the brake shoe to change. Therefore, the brake adjuster testing device can perform performance test on the brake adjuster, and the accuracy of the testing result is obviously improved.
It should be noted that, the brake adjuster testing device not only can perform performance test on the brake adjuster, but also can perform fatigue test on the brake adjuster, that is, the number of times that the brake adjuster 20 to be tested can be extended or contracted by frequently moving the position of the adjusting structure 50. The test results of the performance test and the fatigue test can be used as the basis for judging whether the brake regulator is qualified or not.

The limit protrusion 33 is used to cooperate with the stop iron 21 to trigger the brake adjuster 20 to be tested to act.

It should be noted that, in other embodiments, the limiting structure may be a mounting seat and a control lever mounted on the mounting seat (the control lever is a control lever carried by the brake adjuster 20 to be tested)
After the brake cylinder 61 is inflated, the driving rod pushes the brake adjuster 20 to be tested to move, when the distance between the limit convex part 33 and the stop iron 21 is gradually reduced to be in contact, the brake adjuster 20 to be tested is triggered to act, the stroke of the brake cylinder 61 is kept unchanged, whether the brake adjuster 20 to be tested can automatically extend to compensate the variable quantity of the wheel shoe gap is tested, and the performance of the brake adjuster 20 to be tested is judged to be in conformity with the standard (only the condition that the wheel shoe gap is larger than the stroke of the brake cylinder is used for illustration, and other conditions are not repeated).
