Abstract

The invention discloses sleeper beam plug-in special pressure testing equipment. The equipment comprises a cover plate sealing device of a sealing axial groove, and at least one side wall sealing device of a closed cavity formed by a sealing side wall through hole. All the side wall sealing devices are optionally provided with a gas transmission pipeline which is connected with the closed cavity and is used for inflating or venting the closed cavity. The gas transmission pipeline is provided with a control valve and a pressure detection component. Firstly, the cover plate sealing device is started to seal an axial groove, and then the side wall sealing device is activated to seal all side wall through holes to form the closed cavity. Then, the control valve is adjusted to make the gas transmission pipeline inflate the closed cavity, the pressure detection component detects whether the closed cavity maintains current pressure for a period of time after being filled with a gas, and if so, gas tightness is proved to be good, and if not, the gas tightness is not qualified. The control valve is then adjusted to make the gas transmission pipeline discharge the gas in the closed cavity. The sleeper beam plug-in special pressure testing equipment can conveniently carry out comprehensive gas tightness detection on a sleeper beam plug-in, and a detection result is relatively reliable.

Description

technical field [0001] The invention relates to the field of corbel plug-in detection, in particular to a special pressure testing device for corbel plug-ins. Background technique [0002] With the development of rail transit vehicles in the direction of intelligence and high speed, the quality requirements for the corbels used to support the rail transit vehicles are increasing. Correspondingly, it is particularly necessary to improve the quality of the corbel inserts installed on the corbels. . [0003] The existing corbel plug-in includes a plug-in flange and a plug-in body arranged coaxially. The plug-in flange is fixed at one end of the plug-in body, and the outer diameter of the plug-in flange is larger than that of the plug-in body. In addition, the bolster insert also includes an axial groove located at the center of the insert flange and the insert main body, and several side wall through holes arranged in the insert main body and penetrating along the thickness di...
