Dynamic geometrical parameter measuring device for train wheel set

Abstract

The invention discloses a dynamic geometrical parameter measuring device for a train wheel set. The device comprises two bases, at least one cross beam connected between the two bases and at least one structured light visual sensor for measuring the geometrical parameter of the train wheel set; the two bases are respectively arranged on the two sides of rails where a train drives. By using the dynamic geometrical parameter measuring device for the train wheel set, the measuring device is unaffected by the vibration of steel rails and sleepers when the train passes by, the speed and the weight of the train passing by is not restricted, and the measuring accuracy can be effectively improved. Moreover, there is no need to build a sunshade rainproof tent or pour a monolithic track bed.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a dynamic measurement device for geometric parameters of a train wheel set. Background technique [0002] There are generally two types of train wheel set detection devices currently in use. One of the detection devices needs to build a greenhouse on the railway line to shield the detection device from stray light interference and rain. This method has potential safety hazards and increases the cost of the measurement device. cost; moreover, it is required that trains can only pass at a low speed of 0-30km / h, which cannot meet the measurement needs under the operating conditions of the main line railway; in addition, it is necessary to pour an integral ballast bed on the track, which is difficult and expensive to construct .

[0002] There are generally two types of train wheel set detection devices currently in use. One of the detection devices needs to build a greenhouse on the railway line to shield the detection device from stray light interference and rain. This method has potential safety hazards and increases the cost of the measurement device. cost; moreover, it is required that trains can only pass at a low speed of 0-30km / h, which cannot meet the measurement needs under the operating conditions of the main line railway; in addition, it is necessary to pour an integral ballast bed on the track, which is difficult and expensive to construct

[0003] Another kind of detection device does not need to build a greenhouse and pour an integral track bed, but a certain amount of sleepers needs to be removed, and rail rows need to be added, so that the weight of the passing train is limited (usually less than 35 tons), and the speed is not high (only Can pass at a speed of 5km / h-50km / h)
