Problems solved by technology
[0005] However, the above-mentioned roadheader fuselage position and posture parameter measurement system cannot realize the positioning of the roadheader when the deflection angle of the roadheader is too large, that is, beyond the range of the laser target, so that the laser cannot be irradiated on the laser target. That is, it cannot meet the real-time positioning requirements of roadheaders in coal mines
Moreover, the laser detection device installed on the roadheader is easily affected by equipment vibration, and the acquisition of deflection angle signals is prone to deviation

The invention discloses a detection device of a deviation angle of a development machine. The detection device comprises a laser emitter, a laser receiving device, a control device and a transporting device for pushing the laser receiving device to move, wherein the transporting device is arranged on a rock wall of the top end under a well; the laser emitter is arranged on a development machine body; the laser receiving device is used for detecting a laser beam emitted from the laser emitter; and the control device is used for obtaining the deviation angle of the development machine according to an actual distance between the laser emitter and the laser receiving device and a movement distance of the laser receiving device. According to the movable laser detection device disclosed by the invention, a measuring range of the laser detection device is increased and the real-time locating requirement of the development machine in a coal mine well can be met; the laser detection device is arranged on the rock wall on the top end of a mine roadway and the laser emitter is arranged on the development machine body, thus the influence of strenuous vibration on the accuracy of the laser detection device when the development machine works is greatly avoided. The invention further discloses a detection method of the deviation angle of the development machine.
Description
technical field [0001] The invention relates to the technical field of detection of the deviation angle of a roadheader, in particular to a detection device and a detection method for the deviation angle of a roadheader. Background technique [0002] The roadway boring machine is a combined unit capable of cutting, loading and transporting, reloading coal and rock, mobilizing walking, and spraying and dust removal. The cantilever roadheading machine is currently widely used in coal and rock roadheading machines at home and abroad. [0003] However, on the basis of following a certain cutting process of the coal roadway, the tunneling driver mainly manually operates the tunneling machine through the handle, which is relatively random. Although there is a mine-used explosion-proof laser pointer to guide the direction of excavation during cutting, it is beneficial to the improvement of construction quality. However, due to the harsh working environment (high gas concentration,...
