The invention relates to the technical field of mining vehicle speed detection, in particular to a mining vehicle speed detection device, and aims to solve the problems of large detection error and low detection precision when an existing vehicle speed sensor is used on a bumpy road surface of an underground coal mine. The invention provides a mining vehicle speed detection device. The mining vehicle speed detection device comprises a flange plate, a Hall element and a magnet element, the plurality of magnet elements are connected to the same-diameter circumference of the flange plate; the lengths of the circular arcs of the adjacent magnet elements are arranged in an arithmetic progression; the Hall element is arranged on the side of the flange plate and used for sensing the magnet element mutually so as to detect the vehicle speed. The structure of the flange plate is changed, so that the sensing distance is increased, in the process that the sensor vibrates along with a vehicle body, mutual sensing square waves of the sensor and the flange plate cannot be lost, counting is complete, and the stability and accuracy of speed measurement are improved.
本发明涉及矿用车速检测技术领域,尤其涉及一种矿用车速检测装置,旨在解决现有的车速传感器在煤矿井下的坑洼路面上使用时存在的检测误差大,检测精度低的问题。本发明提供了一种矿用车速检测装置,包括:法兰盘、霍尔元件和磁铁元件;若干个磁铁元件连接于法兰盘的同直径圆周上;相邻的磁铁元件所在的圆周圆弧长度之间呈等差数列设置;霍尔元件设置于法兰盘侧方,霍尔元件用于与磁铁元件相互感应,以检测车速。本发明中法兰盘结构更改使得感应距离提升,传感器在随车身震动的过程中,与法兰盘的相互感应方波不会产生丢失的现象,使得计数完整,测速的稳定性和精确性提升。
