The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: as Fig. 1, the special-purpose drilling system of tunnel, this colliery control water, 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, the oil circuit of control preventer 1 action and the hydraulic circuit of rig link together, and 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 when prying into the water hole, running into press water especially, drilling rod causes bigger casualty accident together with being subjected 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 by four soket head cap screws with side plate 29, be provided with piston body 26 in the 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, be provided with the oil circuit that is connected cylinder body 28 inner carrier bodies 26 outsides in hinged screw 25 and the articulated joint body 24, loam cake 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 the rig 4 by crossbeam 27, and side plate 29 is provided with union 210, and union 210 is provided with the oil circuit that connects cylinder body 28 inner carrier bodies 26 inboards.When hydraulic oil enters oil cylinder from hinged screw 25 and articulated joint body 24, promote piston body 26 to intermediary movements, 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 loam cake 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 then front clamp device 2 unclamps drilling rod.
As shown in Figure 4, front clamp device 2 is connected with clamper control valve 6 by two sequence valves 5 respectively with main card dish 3, and clamper control valve 6 is connected with fuel tank 10.Main card dish 3 and front clamp device 2 adopt fluid pressure linkage 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 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 values, 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 the 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 specialized apparatus when prying into the water hole, specialized apparatus 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, can tighten the screw mandrel 18 of preventer 1 both sides in addition, can make its machinery locking hole mouth when aneroid presses power.
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 lid 110 with nut 112 by double threaded screw 12 with oil cylinder 13, be provided with piston 16 in the 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 the 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 flashboard glue core 111, have increased the sealing between flashboard 17 and the 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 the rig gearbox and the feed mechanism control valve and control preventer 1 the preventer control valve 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, make preventer 1 closed orifices block water under high pressure, whole being swift in motion then.
In addition to the implementation, the utility model 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 the utility model requirement.
