The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
Remove hydraulic support bearing pin specific purpose tool under a kind of coal mine, extremely shown in Figure 7 such as Fig. 1, comprise hydraulic cylinder 2, hydraulic cylinder 2 is with inlet 3 and liquid return hole 4, be connected with hydraulic cylinder post 5 alive in the hydraulic cylinder 2, hydraulic cylinder 2 front ends are fixedly connected with sleeve 7, hydraulic cylinder post 5 alive is positioned at sleeve 7, hydraulic cylinder post 5 front ends alive are connected with contiguous block 9, have on the contiguous block 9 and wear keyhole 13, wear and be provided with connecting bolt 11 in the keyhole 13, connecting bolt 11 comprises head and screw rod, wears the internal diameter of keyhole 13 greater than the external diameter of connecting bolt 11 screw portions, external diameter less than connecting bolt 11 heads part.
In the present embodiment, contiguous block 9 is " U " character form structure, connecting plate in the middle of contiguous block 9 comprises and the side plate on both sides, have through hole on the side plate, hydraulic cylinder post 5 front ends alive have pinned hole 14, contiguous block 9 and the hydraulic cylinder post 5 of living is connected by pin 10, passes in the through hole of pin 10 on pinned hole 14 and the contiguous block 9, and hydraulic cylinder post 5 front ends of living are positioned in the middle of two side plates of contiguous block 9.Sleeve 7 sidewalls have attended operation mouth 8.Hydraulic cylinder 2 back and side are fixedly connected with handgrip 1.
Remove hydraulic support bearing pin specific purpose tool under this coal mine and also comprise lengthened plate 12, lengthened plate 12 is arc.Hydraulic cylinder 2 is fixedly linked by set bolt 6 with sleeve 7.
Embodiment recited above is described preferred embodiment of the present invention; be not that the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
Use work of the present invention to need to be operated by two people, one people hands handgrip, another people carries out feed flow to the inlet of hydraulic cylinder, hydraulic cylinder produces flexible by the control to inlet and liquid return hole, after hydraulic cylinder post alive stretches out, connecting bolt is connected by screw thread with the hydraulic support bearing pin of the pre-dismounting in down-hole, connect fastening after, to the reverse feed flow of liquid return hole, hydraulic cylinder be dynamically connected piece and the connecting bolt of cornice of living shunk together, by contraction sleeve is combined with the hydraulic support backplate tight, and then personnel decontrol handgrip, away from this specific purpose tool, carry out remote feed flow operation, liquid return hole is carried out disposable feed flow, hydraulic cylinder post alive is shunk fast, the equal in length of the length that the hydraulic support bearing pin is drawn out of and hydraulic cylinder post retraction alive.
If the length of hydraulic support bearing pin is oversize, hydraulic cylinder post retraction alive once can not take out bearing pin, also need the inlet of hydraulic cylinder is carried out feed flow again, hydraulic cylinder post alive is stretched out again, then between sleeve and hydraulic support backplate, install lengthened plate, shrink hydraulic cylinder post alive with backward liquid return hole feed flow, make sleeve, lengthened plate is combined tight with the hydraulic support backplate, then continue again the operation identical with last time, personnel decontrol handgrip, away from this specific purpose tool, carry out remote feed flow operation, liquid return hole is carried out disposable feed flow, hydraulic cylinder post alive is shunk fast.
Repeat above-mentioned steps, until the hydraulic support bearing pin is extracted out fully.
The present invention removes in the work at the support of certain colliery high seam 3 times 7104,7106 fully mechanized coal faces and all uses, safe, fast, efficient, former artificial striking bearing pin approximately needs 4 hours, approximately only need to be less than 3 hours behind use the present invention, when support of average every dismounting can be economized on 1 hour, make the integral body of fully mechanized coal face remove speed about 5-7 days in advance, result of use is good.
In sum, the present invention has the following advantages:
1, equipment volume is little, and is light, convenient operation, and space adaptability is strong;
2, the pulling force that produces is large, even, can finish safely, efficiently the purpose of striking bearing pin;
3, save manually, greatly reduce worker's physical labor intensity.
