【正文】 work on the mobile chute designed. Charging machines at work, riding on the 40 t Liuzi the chute, the bucket will face rake with the loaded coal chute, Liu Zi will Meiyun to face. Chute run institutions from operating motor, take the initiative to round, driven round ponent. Walk through a gear motor slowdown will force the initiative passed round, thus realizing the machine forward and backward. The work pressure of motor running 12. 5M Pa. hydraulic system Hydraulic valve block from the hydraulic system, hydraulic piping and other ponents, cantilever stretching, lifting, rotating, the machine running, the winch, and so on are positive and hydraulic valve block to control. 4. Charging for the work process Scalable cantilever loaded coal principle of the work shown in Figure 2. As with coal at work to be powered by the emulsion medium, it also needs pumping stations equipped with a set of emulsion. Charging the work carried out before mencement emulsion pumping station will be installed near the coaltodoor opened on the appropriate location, operation of the institutions supporting fixed machine fixed, and that is to start working with coal. Figure 2 scalable cantilever with the work principle of coal First of all cantilever will extend to the appropriate length and height, lightload operation of winch will rake bucket of coal Meidui pulled down with coal, and then operated heavy winch will rake will fight back loaded coal chute, it is so cycles, until Coal will Zhuangwan. The plane loaded with coal for the coal in front of the 8 270 mm, about 5 850 mm, height 4 500 mm. 5. Underground industrial test Scalable cantilever with the coal industry underground test in the Jincheng Coal Industry Group of Phoenix Mountain coal mine recovery, in 3314 Southface position, seam thickness of 6. 32 m, bulk density 1. 5 t246。 Warehouse mining。 Coal。. loading mechanism Emulsion carrying bodies from the winch and rake bucket ponent. Emulsion winch 2 Taiwan, one for heavy use, another Taiwan for a lightload。 3) loaded with coal coal scope than the original scope of Coal, increased resource recovery。 rated contains important: 30 kN。 The average ground pressure: MPa。 plate tra ZMC30Hydraulic sideloaded coal unloading equipment supporting the transformation of (achieving Liuzi, belt loaded integration) As ZMC30 type aircraft with the use of coal in underground places, narrow space, the tunnel roof and coal for constraint, loaded with coal in the process of coal needed Liuzi (see Figure 1), the use of roadway transport belt, Liu Zi each Classes should move forward first. If Liu Zi and the lap belt between handled properly, will directly affect the tunneling speed. After leading the mining area and the practice of engineering and technical personnel at the scene, Liu Zi will be the first fixed on the end of the belt, so as to form a whole, to achieve Liuzi belt loaded with the integration so that each class can smoothly shift the slip Figure 1 ZMC30 side dump with the merits of coal (1) wellventilated, mainly in coal Duct not be squeezed, dropped, and always maintain normal airflow, no gas gauge. (2) a large space, work envi
