Mining rail sensor

Abstract

The invention discloses a rail sensor for ores, which comprises a pressure sensor, wherein the pressure sensor is fixed in the middle of the upper end face of a sensor mounting seat through bolts. The rail sensor for the ores is characterized in that two transitional steel rails are also welded on the upper end face of the sensor mounting seat; the transitional steel rails are positioned on the front and the back of the pressure sensor respectively and have the same height with that of the pressure sensor; and the gaps between the transitional steel rails and the pressure sensor are between 1.5 and 2.5 millimeters. The rail sensor for the ores has the advantages that the rail sensor for the ores has a solid structure and reliable performance, can effectively control the gaps between the pressure sensor and the rails, protect the pressure sensor from being damaged, effectively adjust the operating distance between pressure sensors, and obtain accurate monitoring result.

Description

technical field [0001] The invention belongs to a mine production monitoring device for rails, in particular to a mine rail sensor. Background technique [0002] Such as figure 1 , 2 , Shown in 3: the existing mine track sensor is installed between two mine rails, the mine track sensor is composed of a pressure sensor and a sensor mounting seat, wherein the sensor mounting seat is fixed in the concrete foundation, and the pressure sensor is fixed by screws In the middle of the upper end surface of the sensor mounting base, two mining rails are directly pressed against the upper end surface of the sensor mounting base, and are respectively located at both ends of the pressure sensor. The upper end surfaces of the mining rails and the pressure sensor are located on the same plane. Leave a gap of about 2 mm between the rails. [0003] The mine car passes on the track. When the mine car passes by the pressure sensor, the pressure sensor acquires the quality data of the mine c...

AI Technical Summary

Problems solved by technology

However, its technical defects are: the rails are relatively long, their thermal expansion and contraction coefficients are high, and the expansion and contraction value of the rails is too large. When the rails are stretched too long, it is easy to directly contact the pressure sensor and cause damage. When the rails stretch too short , it is easy to cause the gap between the pressure sensor and the mine rail to be too large, sometimes even about one centimeter. When the mine car passes by, it will aggravate the vibration of the mine car and increase the impact force of the mine car on the sensor, thus causing damage to the sensor

[0004] The disadvantage of the prior art is that the gap between the pressure sensor and the track rail cannot be effectively controlled, and when the gap is too large or too small, it is easy to cause damage to the pressure sensor
