[0001] The utility model belongs to sensor installation technical field relates to a pair of shot type grating sensor mounting bracket, especially a pair of shot type grating sensor mounting bracket of adjustable installation position. BACKGROUND

[0002] With the continuous improvement of the level of science and technology, the continuous advancement of production operation equipment automation, intelligentization process, the pair of shot type grating sensor with non-contact measurement, detection precision and detection resolution is high, can realize dynamic detection, the influence of environmental factors is small and so on is widely used in intelligent security, automation production, robot navigation, motion speed measurement, product quality detection and other technical fields. The application of pair of shot type grating sensor in automation control mainly concentrates in relative position detection, special-shaped part detection and abnormal state detection etc., when the pair of shot type grating sensor is applied, the accuracy of the corresponding installation position of sensor transmitting end and receiving end, the adaptability of field operation environment will directly affect the accuracy of its detection result.

[0003] The operation train of railway deployment needs to be formed many times in the transportation process, and the connecting mechanism between the carriages should be connected with the fixed end and the rotating end under normal circumstances. With the increase of the number of formation, it is inevitable that the fixed end of the carriage connecting mechanism will be connected with the fixed end, that is, the carriage connecting dead hook phenomenon, and the two carriages are relatively fixed and cannot rotate. If the carriages in this state enter the unloading machine room for tilting operation, the connecting mechanism of the carriages may be damaged, the unloading machine wheel clamping device, positioning car and other mechanisms may be damaged, and serious accidents such as derailment and carriage dumping may occur. Therefore, accurate detection of whether the connecting mechanism between the carriages exists dead hook condition before the operation train carriage enters the unloading machine room is an important link to ensure the follow-up safe production operation.

[0004] In the train car connection dead hook state detection system used at present, the laser single point ranging device judges the train car connection dead hook state by detecting whether the connecting mechanism air pipe between the train cars exists or not, which is greatly affected by environmental factors, and is easily interfered by foreign matters such as connecting iron chain between the train cars and installation support vibration to cause false alarm. The video monitoring judges the train car connection dead hook state, which is affected by weather, sight, camera monitoring angle, train car connection mechanism label blur and other aspects and cannot accurately judge the train car connection state, and needs manual on-site confirmation, which relatively affects operation efficiency. The opposite type grating sensor is a multi-point light curtain detection, has high detection accuracy and is less affected by environmental factors, can effectively replace the laser single point detection mode, and only needs to accurately align the transmitting end and the receiving end during installation. However, due to the complex railway site environment, scratching and vibration cannot be avoided, which affects the alignment accuracy of the transmitting end and the receiving end, therefore, it is necessary to design an opposite type grating sensor installation support which can reduce the influence of site vibration on sensor relative position detection, improve detection accuracy and effectively ensure the safety of equipment use in site operation.
