Detection device and detection method of gasket of under-vehicle suspension device of motor train unit

Abstract

The invention provides a detection device and a detection method of a gasket of an under-vehicle suspension device of a motor train unit. The detection device comprises a long-shaped base plate, wherein one end of the base plate is a handheld portion, and the other end of the base plate is provided with a measurement portion extending perpendicular to the length direction of the base plate. An extending portion is arranged on one end of the measurement portion and used for extending into a gap between a hoisting frame and the gasket, and a magnet block is fixedly arranged on the other end of the measurement portion. The magnet block is provided with a positioning protrusion which is used for ensuring relative positions of the magnet block and a device connection portion of the gasket. The distance between a vertical face, contacting with the device connection portion, of the positioning protrusion and the tail end of the extending portion is a first judgment distance. According to the detection device and the detection method of the gasket of the underframe suspension device of the motor train unit, through utilization of the extending portion and the positioning protrusion on the magnet block, and 70% width of an elastic portion of the gasket is set to be the first judgement distance when no device is hung on the elastic portion, and accurate, convenient and quick detection for width of the elastic portion of the gasket is realized.

Description

technical field [0001] The invention relates to an EMU maintenance technology, in particular to a pad detection device and method for the suspension equipment under the EMU. Background technique [0002] The under-car suspension equipment of the EMU, such as traction transformers, traction converters, etc., are hoisted under the car through pads; that is, the pads are fixed to the hoisting frame screwed on the side beams of the car body by riveting. Inside. [0003] Such as figure 1 As shown, the gasket is composed of an equipment connection part 101, an intermediate connection part 102, a hoisting frame connection part 103 and an elastic part 104; In the hoisting frame on the side beam of the vehicle body, the elastic part 104 includes a first subsection and a second subsection arranged side by side, and is fixed by an intermediate connection part 102 arranged between the first subsection and the second subsection. They are connected together, while the first subsection ...

Problems solved by technology

[0005] Since the lifting frame connection part 103 of the gasket is fixed in the lifting frame and cannot be seen, in the prior art, the width D of the gasket can only be measured with bayonet pliers, and then the opening of the bayonet pliers is measured. Use this to judge whether the width D is less than 70% of the width D when the equipment is not suspended, and the measurement results obtained in this way have large errors and the measurement operation is inconvenient
