Embodiment Construction
[0013] In the figure, the coal mine roadway excavation anti-deviation system includes a reflector 3, a display screen 4, a compass 5, a laser transmitter 6 and a range finder 7; In the upper part, the console 8 is located above the walking chassis 9, and the front upper part of the walking chassis 9 is provided with a telescopic oil cylinder 10. The instrument 7, the console 8 are also provided with reflective mirror 3 and joystick, the laser emitted by the laser transmitter 6 is captured by the reflective mirror 3, and then the light is reflected to the display screen 4 to form a light spot; The coal wall 1 sends infrared rays, so that the straight-line distance from the coal wall 1 to the entrance of the roadway can be measured, and people can get the daily progress of the excavator. When the excavator deviates from the original direction, the position of the light spot displayed on the display screen 4 will There will be an offset, prompting the operator to adjust the wal...

The invention relates to an anti-shift system for coal mine roadway excavation, wherein the system comprises a reflective mirror, a display screen, a compass, a laser transmitter and a distance measuring instrument. The display screen and the compass are arranged at the upper part of a control console side by side; the control console is located above a walking type chassis; the laser transmitter and the distance measuring instrument are arranged behind a mining vehicle; the reflective mirror and an operation lever are arranged on the control console side by side; lasers transmitted by the laser transmitter are captured by the reflective mirror, and then light rays are reflected to the display screen to form a light spot; and the distance measuring instrument transmits an infrared ray to a coal wall, so that the leanerlinear distance from the coal wall to a roadway access can be measured. By the anti-shift system for coal mine roadway excavation, the walking direction of the mining vehicle can be effectively located, the mining vehicle is prevented from shifting away from a predetermined linear direction, convenience in operation is provided, production cost is saved, and great convenience for excavating mines is provided.
Description
technical field [0001] The invention relates to an anti-deviation system, in particular to an anti-deviation system for coal mine roadway excavation that can effectively prevent deviation from a predetermined straight line position when digging a coal mine roadway. Background technique [0002] At present, when excavating roadways in coal mines, it is necessary to use more complicated technology to prevent the excavator from shifting from the predetermined straight line position, which is not only inconvenient to operate, but also increases the production cost virtually. It is easy to shift the direction and affect the progress of the project. Contents of the invention [0003] In order to overcome the problem that it is easy to deviate from the predetermined straight line when excavating a coal mine roadway, the present invention provides an anti-deviation system for coal mine roadway excavation. The machine deviates from the predetermined straight line, easy to operate,...
