Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As described in Figure 1, the utility model be provided with on the support of existing fully-mechanized mining working be made up of fixed head 1, expansion plate 2 and self locking hydraulic lifting jack 3 anti-ly fly plate, described fixed head 1 is arranged on force piece 4, the two ends up and down of described expansion plate 2 and the two ends up and down of fixed head 1 slidably connect together, the base 31 of described self locking hydraulic lifting jack 3 is fixed on fixed head 1, and the push rod 32 of self locking hydraulic lifting jack 3 is fixed on expansion plate 2.Fixed head 1 and expansion plate 2 all adopt shaped steel and Plate Welding to form, there is certain intensity, in the spoil that can effectively prevent work plane from falling down or coal admission passage, self locking hydraulic lifting jack 3 control is adopted to prevent flying the scaling operation convenience of plate and do not need to continue to provide oil pressure, decrease energy consumption, safe and reliable.
In the process of mining, the high and low position of force piece 4 can be changed as required at any time, in order to ensure that work plane is prevented flying the effect that device can play protection when diverse location, spy anti-will fly plate and be divided into upper and lower two covers, on a set of base 42 be arranged on below force piece 4 below, on a set of side guard board 41 be arranged on above force piece 4 above, when installing need the tune of bracket base to set a roof beam in place and the side guard board of back timber is opened entirely, ensure that force piece all can cover passage when extreme higher position.Simultaneously in order to ensure that force piece upper and lower two covers when decline prevent that flying plate can not interfere, anti-for the upper and lower two covers plate that flies is being greater than the distance of 180mm perpendicular to staggering mutually in the anti-direction flying plate, two-layerly anti-fly plate and can coincide together up and down when work plane declines, improve the anti-scope of application flying device.
Because there is no fixation means on the base plate 42 and side guard board 41 of force piece 4, so conveniently dismounting is anti-fly device, the base plate 42 and side guard board 41 of force piece are provided with multiple otic placode 43, and this otic placode 43 welds after roughly should locating according to the anti-size flying plate when the tune of bracket base is set a roof beam in place and entirely opened with the side guard board of back timber again.
In order to make, anti-to fly device dismounting more convenient and improve its scope of application, and the through hole that described fixed head 1 is connected with described otic placode 43 is set to slide opening 11, and the length direction of described slide opening 11 is consistent with the length direction of fixed head 1 fixed end.Make slide opening be convenient on the one hand expansion plate 2 outreach inadequate time, fixed head 2 can suitably adjust forward, is also convenient to left mining face on the other hand and right mining face levels is used interchangeably timing.
Because spoil or coal all may be fallen down at any time in work plane top, and fixed head 1 only has while fix with force piece, can make when block stone is larger to prevent that flying plate sends distortion, if self locking hydraulic lifting jack 3 is all fixedly connected with expansion plate may be made to move because being out of shape interference with fixed head 1 and expansion plate 2, so adopt hinged mode the base 31 of self locking hydraulic lifting jack 3 and push rod 32 to be connected together with fixed head 1 and expansion plate 2 respectively, make to prevent that flying plate is provided with certain flexibility, can adapt to slight distortion.
Further, because expansion plate 2 needs frequent telescopic moving, be connected more reliable in order to make expansion plate 2 with fixed head 1, mobile more steady, be provided with relative draw-in groove 12 at the two ends up and down of described fixed head 1, the two ends up and down of described expansion plate 2 are provided with roller 21, and described roller 21 is stuck in the draw-in groove 12 of fixed head 1, decrease friction and noise by roller 21 is mobile in draw-in groove 12, make telescopic moving more steady.
As shown in Figure 2, in order to control the anti-telescopic moving flying plate of upper and lower two cover simultaneously, need simultaneously to anti-self locking hydraulic lifting jack 3 oil-feed and the oil return flying plate of upper and lower two cover, so the feed tube 33 of two self locking hydraulic lifting jacks 3 and liquid back pipe 34 all connected together respectively by the main feed tube 9 of breeches pipe 6 and oil cylinder and main liquid back pipe 10, so just can realize the telescopic moving of upper and lower two self locking hydraulic lifting jacks 3 simultaneously.
Further, for the ease of operating personnel needs by time can open in outside and anti-fly device, by after can be closed inside adjacent frame, operating valve 5 is all provided with in the described both sides of preventing flying the force piece of plate that are provided with, the interface that described two operating valves 5 are identical is first connected together by breeches pipe 7,8 and is linked in main feed tube 9 and main liquid back pipe 10 again.
At work plane, one group of trend is installed from lower outlet up the 10th frame hydraulic support to prevent flying device, installs one group every 10 frame hydraulic supports later.
