Description
Technical field
A kind of coal bed gas pipe arranging device of the utility model belongs to coal-bed gas exploitation device technique field.
Background technology
The exploitation of coal bed gas needs at coal mine down-hole drilling, then connects aspiration pump with outside the coal bed gas out well, because the hole of boring is longer, reaches 1000 meters most, and general more than 200 meters, when the coal seam was softer, local Coal Seam Collapse easily the coal hole plug, affected the extraction of coal bed gas; The mode that intubate is also arranged is about to stamp aperture on the plastic conduit sidewall, will manage and insert in the coal inlet, the method of this direct cannulation is easily stopped up the aperture of plastic pipe sidewall on the one hand, and impact is bled, in addition, the plastic pipe mechanical strength is lower, and the length of inserting is shorter, meets obstructions and can not push ahead; If the employing steel pipe, cost is higher on the one hand, on the other hand, affects the digging of follow-up mine, when digger contacts fragile digger, also easily produces spark with steel pipe, affects safety in production.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: provide a kind of intubate conveniently and cheap coal bed gas pipe arranging device.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of coal bed gas pipe arranging device, comprise: hollow drill, taper plug, umbrella anchor head and floral tube, described umbrella anchor head and floral tube all are sleeved on the inside of hollow drill, and an end of described umbrella anchor head is connected on the termination of floral tube, have a plurality of through holes on the floral tube, be fitted with the taper plug on the termination of hollow drill;
The structure of described umbrella anchor head is: an end of connecting rod has screw thread, the other end of connecting rod is fixed with hemispherical ends, the junction of described hemispherical ends and connecting rod is provided with groove, one end of a plurality of sheet metals is hinged in the described groove, be provided with spring between each sheet metal and the connecting rod, spring is in compressive state, and the other end of sheet metal is withstood on the inwall of described hollow drill;
Connecting rod in the described umbrella anchor head is threaded connection on the termination of described floral tube.
Described floral tube is plastic conduit.
Described hollow drill is Metallic rod.
The length of described hollow drill is 3M.
The end that described taper plug is inserted into hollow drill inside is shaft-like, and the other end of taper plug is hemispherical.
The beneficial effect that the utility model compared with prior art has is: the utility model can be put coal inlet with the floral tube that is used for the extraction coal bed gas smoothly, do not stop up simultaneously the aperture of floral tube sidewall, solve the stringing difficult problem in the coal bed gas extraction, simultaneously, cost is lower, has also guaranteed the safety of follow-up driving; Whole apparatus structure is succinct, and is easy to install.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of umbrella anchor head in the utility model;
Among the figure: 1 is that hollow drill, 2 is that taper plug, 3 is that umbrella anchor head, 4 is that floral tube, 5 is that hemispherical ends, 6 is that connecting rod, 7 is that sheet metal, 8 is spring.
The specific embodiment
As depicted in figs. 1 and 2, a kind of coal bed gas pipe arranging device of the utility model, comprise: hollow drill 1, taper plug 2, umbrella anchor head 3 and floral tube 4, described umbrella anchor head 3 and floral tube 4 all are sleeved on the inside of hollow drill 1, and an end of described umbrella anchor head 3 is connected on the termination of floral tube 4, have a plurality of through holes on the floral tube 4, be fitted with taper plug 2 on the termination of hollow drill 1.
The structure of described umbrella anchor head 3 is: an end of connecting rod 6 has screw thread, the other end of connecting rod 6 is fixed with hemispherical ends 5, described hemispherical ends 5 is provided with groove with the junction of connecting rod 6, one end of a plurality of sheet metals 7 is hinged in the described groove, be provided with spring 8 between each sheet metal 7 and the connecting rod 6, spring 8 is in compressive state, the other end of sheet metal 7 is withstood on the inwall of described hollow drill 1, the quantity of sheet metal 7 can be 4 or 6, and the connecting rod 6 in the described umbrella anchor head 3 is threaded connection on the termination of described floral tube 4.
Described floral tube 4 is plastic conduit, and floral tube 4 external diameters are 58MM, the long 5M of every joint, and floral tube 4 can more piece make up, and described hollow drill 1 is Metallic rod, and hollow drill 1 external diameter 80MM, internal diameter 70MM, long 3M, hollow drill 1 also can the more piece combinations.
The end that described taper plug 2 is inserted into hollow drill 1 inside is shaft-like, can make things convenient for like this plug-in mounting of taper plug 2 and hollow drill 1, the other end of taper plug 2 is hemispherical, is conducive on the one hand hollow drill 1 and advances, and prevents that simultaneously coal dust from entering hollow drill 1.
During use, bored first the coal hole in 120-150MM aperture with rig, taper plug 2 is inserted into the front end of hollow drill 1, hydraulic feed device with rig pushes away hollow drill 1 and the floral tube 4 that connects in the coal inlet section by section simultaneously, when the certain distance of bottom, distance coal hole, general 2-5M, with rig floral tube 4 is pushed a segment distance, 1-2.5 meters, taper plug 2 is backed down, umbrella anchor head 3 is released outside the hollow drill 1, the umbrella sheet metal 7 of umbrella anchor head 3 flicks under the effect of spring 8, is stuck in the coal hole, then hollow drill 1 is withdrawed from the coal hole, floral tube 4 is stayed in the coal hole, finishes the setting of floral tube.
The utility model can be put coal inlet with the floral tube that is used for the extraction coal bed gas smoothly, does not stop up the aperture of floral tube sidewall simultaneously, solves the stringing difficult problem in the coal bed gas extraction, and simultaneously, cost is lower, has also guaranteed the safety of follow-up driving; Whole apparatus structure is succinct, and is easy to install.
