Description
Technical field
The utility model relates to the rolling stock apparatus for examination and repair, specifically is that a kind of angle cock detects gripping mechanism.
Background technology
Angle cock is the critical component that is connected between brake pipe and the brake hose of rolling stock, and this device is used to cut off that locomotive is responsible for vehicle braked, being connected between follow-up locomotive and the vehicle braked person in charge; In train travelling process, if poorly sealed or internal damage appears in angle cock, can cause that then train produces unconventional braking when driving, therefore the inner body of angle cock and the safe operation that the serviceability quality directly concerns train, need regularly the angle cock inner chamber to be carried out air-tightness for this reason and detect, yet do not have a kind of apparatus for examination and repair that can carry out the air-tightness detection at present angle cock.
Summary of the invention
The utility model does not still have a kind of problem that can carry out the apparatus for examination and repair of air-tightness detection to angle cock at present in order to solve, and provides a kind of angle cock to detect gripping mechanism.
The utility model is to adopt following technical scheme to realize: angle cock detects gripping mechanism, comprises prelocalization seal receptacle, back location seal receptacle and positioning plate; The posterior face of positioning plate is fixed with front frame and after poppet respectively, is fixed with the clamping cylinder between front frame and the after poppet; Clamp the cylinder front end and be connected with ejecting rod of cylinder; Location, described back seal receptacle comprises rear center's fix shaft that its rear end and ejecting rod of cylinder are fixedly coupled axle and are fixed in the adapter shaft front end; Rear center's fix shaft front end is socketed with outside nest and back seal ring respectively, and the back seal ring is positioned at outside nest front side; The front end face of rear center's fix shaft has the center air-filled pore, and the outside face of outside nest has the side position air-filled pore that connects with the center air-filled pore; Described prelocalization seal receptacle comprise have on it base that has through hole on inclined-plane and the inclined-plane, the rotating shaft that runs through the base left and right sides, with and the preceding centralized positioning axle of lower end and rotating shaft socket; Preceding centralized positioning axle is positioned at the through hole on the base, and the axis of rotating shaft is vertical mutually with the axis of preceding centralized positioning axle; The upper surface of preceding centralized positioning axle has the central row pore, and the end face of rotating shaft has the side position deflation hole that connects with the central row pore; Preceding centralized positioning axle upper end is socketed with preceding seal ring; Base is fixed in the anterior face of positioning plate.
Working process is as follows: earlier angle cock is placed on the prelocalization seal receptacle, the elbow of angle cock is engaged with preceding seal ring, then to clamping cylinder charge, clamp cylinder and promote the seal receptacle reach of location, back by ejecting rod of cylinder, rear center's fix shaft is put in the gas port of angle cock afterbody, the angle cock afterbody engages with the back seal ring, thus its bore seal is fixed and made to the angle cock chucking; Sealing finishes, and angle cock is inserted source of the gas, and source of the gas is inflated to the angle cock inner chamber by the gas port of side position air-filled pore, center air-filled pore, angle cock afterbody successively, begins that angle cock is carried out air-tightness and detects; Air-tightness detects and finishes, and the gas of angle cock inner chamber is discharged by central row pore, side position deflation hole successively; Because the style characteristic of angle cock, form between the elbow of angle cock and the preceding seal ring tiltedly down to application force, for avoiding this application force to influence the elbow of angle cock and the sealing effectiveness between the preceding seal ring, in the elbow of angle cock and process that preceding seal ring engages, preceding centralized positioning axle can carry out trace with rotating shaft and rotate (slewing area does not exceed the through hole scope of base), seal ring possesses certain freedom of movement before making, can improve the elbow of angle cock and the leak tightness between the preceding seal ring thus, it is more accurate that air-tightness is detected.
The utility model is simple in structure, reasonable in design, and having solved does not still have a kind of problem that can carry out the apparatus for examination and repair of air-tightness detection to angle cock at present, is applicable to that the air-tightness of all kinds of angle cocks detects.
