Description
Technical field
The utility model belongs to rail wagon brake cylinder field tests, is specifically related to a kind of rail wagon brake cylinder cyclic test frock.
Background technology
Rail wagon brake cylinder is the critical component that contacts Pneumatic brake systems and foundation brake system in brake system, once checking cylinder breaks down, the whole brake system of vehicle will break down, and seriously jeopardizes traffic safety.
In order to ensure the stable performance of checking cylinder, according to the technical conditions of checking cylinder, the manufacturer of checking cylinder must regularly carry out cyclic test to the checking cylinder of producing.Current checking cylinder circulation test device just installs a block additional, in order to limit the stroke of checking cylinder before checking cylinder piston.While utilizing block to limit checking cylinder stroke, checking cylinder, under very little pressure condition, has just reached stroke requirement, and the increase of later stage brake-cylinder pressure can only test the withstand voltage of checking cylinder.Because railway wagon brake is that each braking accessory all can produce some elastic deformations after stressed, therefore, brake-cylinder pressure is higher, and the stroke of checking cylinder also can be larger.In fact spinning seal type brake cylinder pressure is larger, and the y-type seal ring on its piston and the friction force of the inside wall of cylinder are just larger, and y-type seal ring moves and can lag behind piston, exists y-type seal ring to rout up the possibility of mounting groove.
Current checking cylinder test unit can only simulating brake cylinder stroke, actual loading situation while can not simulating brake cylinder piston release, in the time that brake-cylinder pressure is greater than 30kPa, checking cylinder has reached impulse stroke, and later stage brake-cylinder pressure rises to 360kPa, actual just checking cylinder piston supercharging under static state, can not simulate the force-bearing situation of actual checking cylinder on vehicle.Therefore, existing checking cylinder circulation test device is difficult to the problem of finding that checking cylinder exists.
Summary of the invention
The purpose of this utility model will overcome above-mentioned deficiency exactly, and the rail wagon brake cylinder cyclic test frock of a kind of energy tested checking cylinder of real simulation force-bearing situation in actual condition is provided.
For achieving the above object, the rail wagon brake cylinder cyclic test frock that the utility model is designed, comprise base, on described base, be provided with mounting platform, its special character is: a side of described mounting platform is provided with the checking cylinder mount pad for fixing tested checking cylinder; The opposite side of described mounting platform is provided with spring fitting box, in described spring fitting box, is provided with spring assembly; Described mounting platform middle part is provided with bracing frame, is shelved with power transmission push pedal on support frame as described above; Described power transmission push pedal is under operating condition of test, and one side is connected with the brake cylinder push bar of tested checking cylinder, its opposite side and spring assembly front end butt.
Further, described power transmission push pedal is hinged by round pin and brake cylinder push bar, for convenience detach.
Preferably, the inverted U supporting member that support frame as described above is arranged in below, power transmission push pedal two ends by pair of parallel forms, and such design makes simple in structure lightweight, has saved cost.
Further, a side of described spring fitting box is provided with reinforcement gusset, increases the stressed of spring fitting box.
Again further, it also comprises adjustment pad, and described spring fitting box is provided with cushion block opening corresponding to spring assembly rear end, and described adjustment pad is inserted into spring assembly rear end from cushion block opening when needed, the convenient stroke of adjusting tested checking cylinder.
Again further, described adjustment pad is provided with polylith, and the every thickness of adjusting pad is different.Preferably, base, mounting platform, checking cylinder mount pad, spring fitting box, bracing frame are integral type welded frame structure, and the structure that is is more firm.
The utility model has the advantage of: by spring assembly baffle plate is set, simulate the elastic deformation of the stressed rear generation of each braking accessory in freight car braking process, can simulate more realistically like this force-bearing situation of tested checking cylinder, thereby fully expose the problem of newly-designed checking cylinder or the new checking cylinder existence of making.
