Abstract
The invention relates to a drilling system special for coal mine underground tunnel water control. The drilling system special for the coal mine underground tunnel water control comprises a drilling machine, a main chuck and a front clamp holder are arranged on the drilling machine, a blowout preventer is arranged on a position of a drilling hole of the drilling machine, an oil way which controls movement of the blowout preventer is connected with a hydraulic oil way of the drilling machine, and the front clamp holder and the main chuck form a linkage. The drilling system special for the coal mine underground tunnel water control has the advantages that when the main chuck clamps a drill stem to drill, the main chuck needs to be loosened for avoiding the fact that a user is injured due to the fact that the stem slipping off the drilling hole because the stem is stressed by water in the drilling hole or dead load of a drilling tool when the drill stem is mounted. Due to the fact that the drill stem ids clamped by the front clamp holder, accidents are avoided. Besides, in the process of drilling, when the pressure in the drilling hole reaches to a certain value, the drilling machine stops working immediately and the blowout preventer is enabled to close the drilling hole, and thus the fact that high pressure water does not pour out is guaranteed.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment: as Fig. 1, the anti-special jewel of harnessing the river of this coal mine gallery is visited system, comprise rig 4, rig 4 is provided with main card dish 3 and front clamp device 2, the position, aperture that rig 4 is drilled is provided with preventer 1, control the oil circuit of preventer 1 action and the hydraulic circuit of rig and link together, front clamp device 2 and main card dish 3 form interlock.
In boring procedure particularly when " falling bar; add bar " work the main card dish 3 of rig 4 to unclamp drilling rod, can make drilling rod moment fall in the hole or skid off outside the hole and cause the accident this moment, when running into press water especially when prying into the water hole, drilling rod causes larger casualty accident together with being subject to the pressure in the hole, and front clamp device 2 can effectively be avoided the generation of above accident.
as shown in Figure 3, described front clamp device 2 comprises cylinder body 28, cylinder body 28, back cylinder cover 23 is connected with side plate by four soket head cap screws connections, be provided with piston body 26 in cylinder body 28, slips 21 is connected with piston body 26 by T-slot, back cylinder cover 23 is provided with hinged screw 25 and articulated joint body 24, hinged screw 25 be provided with the oil circuit that connects cylinder body 28 inner carrier body 26 outsides in the articulated joint body is connected, upper cover 22 is connected with side plate 29 by screw, cylinder body 28 belows are provided with crossbeam 27, front clamp device 2 is fixed on rig 4 by crossbeam 27, side plate 29 is provided with union 210, union 210 is provided with the oil circuit that connects cylinder body 28 inner carrier body 26 inboards.When hydraulic oil entered oil cylinder from hinged screw 25 and articulated joint body 24, pushing piston body 26 was to intermediary movements, and slips 21 also is synchronized with the movement along with piston body 26, clamps drilling rod.Slips 21 can only be done radial motion under upper cover 22 and crossbeam 27 spacing.When hydraulic oil entered oil cylinder from union 210, piston body 26 moved laterally and namely drives slips 21 and move laterally, and front clamp device 2 unclamps drilling rod.
As shown in Figure 4, front clamp device 2 is connected with the main card dish respectively and is connected with clamper control valve 6 by two sequence valves 5, and clamper control valve 6 is connected with fuel tank 10.Main card dish 3 and front clamp device 2 adopt fluid pressure linkage to control.When big-elevation boring and spy discharge water boring, often need down bar, add bar, unload bar work, for preventing that unclamping the beginning drilling rod at the main card dish skids off or fall in the hole in the hole and cause the accident, front clamp device 2 main card dish 3 is with it realized interlock control, be before main card dish 3 unclamps drilling rod, front clamp device 2 clamps drilling rod; Before main card dish 3 clamped drilling rod, front clamp device 2 unclamped, and by adjusting sequence valve, can adjust the time difference of front clamp device 2 and 3 interlocks of main card dish, to guarantee the safety of rig working environment.Only need to operate a hydraulic handle during operation gets final product.
Clamper control valve 6 is connected with overflow valve 7, and overflow valve 7 is connected with fuel tank 10 by gear pump 9.By giving overflow valve 7 default pressure value, the numerical value of the pressure meter 8 on rig just starts overflow valve 7 greater than this numerical value, and oil is got back in fuel tank 10 by gear pump 9, plays the protective effect to hydraulic system.
The anti-regulation of harnessing the river in country colliery, to use special-purpose equipment when prying into the water hole, special-purpose equipment refers to that the aperture safety device is often arranged, make preventer 1 closed orifices by the hydraulically operated valve on the operation rig, prevent that water under high pressure from leaking outside, avoid water leak accident, separately can tighten the screw mandrel 18 of preventer 1 both sides, can make it lock the aperture without hydraulic power tool on opportunity.
As shown in Figure 2, described preventer 1 comprises casing 11, casing 11 both sides are connected with lid 110 by fastening bolt 15, the locking closure 14 of both sides is connected with oil cylinder and is connected with nut and is connected with lid 110 by double threaded screw 12, be provided with piston 16 in oil cylinder 13, piston 16 outer ends are connected with screw mandrel 18 by screw thread, the outer end of screw mandrel 18 is flat square structure, piston 16 the inners are located in the groove of flashboard 17, casing 11 is provided with two tubing interfaces 19, be respectively equipped with the oil circuit that connects two side cylinders 13, the flashboard 17 of both sides works in coordination when oil-feed and cuts out.When hydraulic oil flows in oil cylinder 13 from tubing interface 19, the flashboard 17 of both sides inwardly moves, and clamps drilling rod and closed orifices, prevents that the high-rise Shuitu in the hole from going out.Flashboard 17 inboards are provided with gate rubber core 111, have increased the sealing between flashboard 17 and drilling rod, more effectively prevent gushing out of water under high pressure.
The position, aperture that described rig 4 is drilled is provided with a flow transmitter, flow transmitter respectively with rig 4 on rig gearbox and feed mechanism control valve and the preventer control valve of controlling preventer 1 be connected.When the flow that records position, the aperture water of flowing through when flow transmitter surpasses setting value, sensor is successively given rig gearbox emergency stop switch, feed mechanism control valve, preventer control valve send signal, make rig stop the work of creeping into, then make preventer 1 closed orifices block water under high pressure, whole being swift in motion.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
