Optical fiber releasing equipment of underground moving equipment of coal mine

Abstract

The invention relates to optical fiber releasing equipment of underground moving equipment of a coal mine. The equipment comprises a box body, a box cover, a turntable, a stand column, a first guide wheel, a second guide wheel, a lead pipe and a power mechanism; an accommodating cavity with an open top is defined by the box body, the box cover is rotatably connected with the box body, the turntable is positioned in the accommodating cavity, the turntable is rotatably connected with the box body, the vertical stand column is arranged on the turntable, an optical fiber wire package is placed onthe turntable, and the optical fiber wire bag sleeves the stand column; the first guide wheel and the second guide wheel are arranged on the inner side wall of the accommodating cavity and are rotatably connected with the box body, and the outer wheel periphery of the first guide wheel and the outer wheel periphery of the second guide wheel are spaced and define a guide space; the power mechanismis connected with the first guide wheel and the second guide wheel, the power mechanism is suitable for driving the first guide wheel and the second guide wheel to rotate, and the rotation directionsof the first guide wheel and the second guide wheel are opposite; and the lead pipe is arranged on the outer side wall of the box body, and optical fibers of the optical fiber wire package penetrate through the guide space and the lead pipe and protrude outwards.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to an optical fiber release device for underground mobile equipment in coal mines. Background technique [0002] The underground environment of coal mines is complex. At present, underground communication is mainly wired communication, and optical fiber communication equipment is a mainstream mode of underground wired communication. For mines under normal conditions, the communication optical fiber is often laid when the mine is built, but after an accident, the pre-laid optical fiber is often destroyed; or for communication that needs to be moved underground Devices, especially small mobile devices, do not have the ability to drag cables or optical fibers due to their own power. [0003] A patent with the application number CN201310448325.1 discloses an optical fiber release device for underground mobile equipment in coal mines. Shell, introduction device, and lower cylinder; the ...

Problems solved by technology

When in use, place the fiber optic cable package in the lower barrel 9, and the two ends of the optical fiber can be drawn out from the outer guide tube 2 and the introduction device 8 respectively. However, multiple optical fibers are usually wound on the fiber cable package, causing the staff to stretch When using optical fiber, due to the high friction force on the optical fiber, it will greatly increase the working intensity of the staff
