Embodiment Construction

[0026] The following embodiments will further describe the present invention in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 As shown, the device for testing the performance of a railway vehicle air storage cylinder includes: a frame 1, an air storage cylinder fixture 2, a water supply and air supply system 7, a pressure relief cylinder 3, a water tank 4, and a casing 6. Frame 1 is a stepped shape with low left and high right, legs 8 are welded to the bottom of frame 1, water tank 4 is welded to the left side inside frame 1, guide rails 5 and pressure relief cylinders 3 are arranged front and back on frame 1 above water tank 4. The two guide rails 5 are parallel to each other and placed horizontally, and are fixed to the frame 1 by screws, and a pair of clamps 2 for the air storage cylinder are placed on the guide rails 5 . The water supply and air supply system is on the right side of the frame 1, and the water pump 7.1, the pneumatic ...

Abstract

The present invention relates to the railway vehicle detection equipment technology field, in particular to a micro-control air cylinder wind-water pressure testbed which is used for detecting the performance of an air cylinder on a railway vehicle by the microcomputer control, and is simple in detection program and is time-saving and labor-saving in operation. The micro-control air cylinder wind-water pressure testbed comprises a rack, air cylinder fastening tools, a pressure release cylinder, a water tank, guide rails, a chassis, a water and wind supply system and supporting feet. The rack is a stepped shape of which the left is low and the right is high, the two air cylinder fastening tools are arranged in front of the upper end of the left side of the rack and are both in slip connection with the rack via the guide rails. The two guide rails are parallel with each other and are placed horizontally, and the pressure release cylinder is fixed behind the upper end of the left side of the rack. The water tank is fixed inside the left side of the rack, and the water and wind supply system is arranged inside the right side of the rack. The micro-control air cylinder wind-water pressure testbed of the present invention is mainly used for the detection of the railway vehicle air cylinder.

Description

technical field [0001] The invention relates to the technical field of railway vehicle detection equipment, and more specifically, relates to a micro-controlled wind and water pressure test bench for an air storage cylinder, which controls the performance of the air storage cylinder on a railway vehicle through microcomputer control. Background technique [0002] The air storage cylinder is a pressure vessel used in the braking process of the freight car. After assembly and welding, the water pressure and wind pressure test must be carried out according to the "Regulations for Overhauling the Braking Device of Railway Freight Cars". And the wind pressure test above 600kPa, keep the pressure for 3 minutes, no leakage, no permanent deformation, and the water in the cylinder must be removed after the water pressure test. The existing wind and water pressure test bench for air storage cylinders is only suitable for one specification of air storage cylinders, the operation is com...
