kind of gas drilling level pressure slip casting jointing equipment, including the entrance point of mutual intercommunication, exit end and warning end, install alarm device in the warning end, alarm device includes the power, reset spring, piston and alarm lamp, inside piston seal arranged in warning end, the outer terminal surface of piston is close to edge and middle part do not is connected with reset spring and conductive spring, fixed connection is on solid fixed ring in addition, solid fixed ring fixed connection is inside warning end outer end, power fixed connection is at solid fixed ring middle part, power outer end and inner are anodal and negative pole respectively, anodal and conductive spring have controller and alarm lamp through wire series connection, alarm lamp fixed connection is at warning end tip.

Preferably, the alarm lamp is fixedly connected to the fixed wafer, the transparent hemispherical lampshade is sleeved outside the fixed wafer, and the fixed wafer is fixedly connected to the outer end of the alarm end.

Preferably, the conductive spring is fixedly connected to the insulating plate, the insulating plate is fixedly connected to the surface of the piston, and the wire portion connected with the conductive spring is a spiral telescopic wire.

Preferably, the number of the return springs is four, and the return springs are uniformly arranged in the circumferential direction.

Preferably, the surfaces of the inlet end and the outlet end are provided as threaded portions.

Compared with the prior art, the utility model has the beneficial effects of, the utility model discloses pass through the entrance point entering at the thick liquid, when flowing in inside, partial thick liquid meets the motion match of the inside of circle, because reset spring's resistance effect, the piston displacement is less, reset spring and the separation of power negative pole, the alarm lamp is not bright, the slip casting liquid flows through the thick liquid exit end, get into the peripheral slip casting space of drilling through the joint, treat the thick liquid and fill up the back, under the grouting pump effect, the thick liquid is to piston extrusion force grow, the piston moves to the power negative pole, treat when the conductive spring of low resistance and power negative pole contact, the alarm lamp brightens, the slip casting reaches and sets for slip casting pressure, stop the slip casting, the utility model discloses the device is simple, convenient to use, the operation is swift, detects sensitively, when changing gas drilling slip casting pressure, only need change with it can to change supporting spring with it, with the solution need rely on observing during the slip casting bucket in the colliery to return the thick liquid not reduce or tunnel surface to be full with the judgement drilling slip casting, the efficiency is low, the effect is poor, the effect of the special pressure slip casting is caused to make the great scheduling problem of the buffering effect of still better slip.

Detailed Description

The present invention will be described with reference to the drawings and the specific embodiments in .

Embodiment 1 as shown in fig. 1-3, gas drilling constant pressure grouting connection equipment is of a T-shaped structure and comprises an inlet end 1, an outlet end 2 and an alarm end 3 which are mutually perpendicular and communicated, wherein an alarm device is installed in the alarm end 3 and comprises a power supply 5, a return spring 13, a piston 6 and an alarm lamp 4, the piston 6 is hermetically arranged in the alarm end 3, the outer end face of the piston 6, which is close to the edge and the middle, is respectively connected with the return spring 13 and a conductive spring 12, the other end of the return spring 13 is fixedly connected to a fixing ring 9, the fixing ring 9 is fixedly connected to the inner end of the alarm end 3, the power supply 5 is fixedly connected to the middle of the fixing ring 9, the outer end and the inner end of the power supply 5 are respectively an anode and a cathode, the anode and the conductive spring 12 are connected in series with a controller and the alarm.

Preferably, the alarm lamp 4 is fixedly connected to a fixed wafer 7, a transparent hemispherical lampshade 8 is sleeved outside the fixed wafer 7, and the fixed wafer 7 is fixedly connected to the outer end of the alarm end 3.

Preferably, the conductive spring 12 is fixedly connected to the insulating sheet 11, the insulating sheet 11 is fixedly connected to the surface of the piston 6, and the portion of the wire connected to the conductive spring 12 is a spiral expansion wire.
