Abstract
The utility model discloses a combination extension rod type water supply device. The combination extension rod type water supply device comprises a drill, an adapter connector, an improved combination type lengthened connecting rod drill pile and a side direction water supply device and the like. The combination extension rod type water supply device is matched with a roof bolter to be used. The combination extension rod type water supply device has the advantages of being convenient to operate, fast in drilling rate, stable, high in reliability and safe to use and the like. The combination extension rod water type supply device can be used in a construction rock bolt and an anchor cable hole, and at the same time, the combination extension rod type water supply device can be used with an observing hole.
Description
Technical field
The utility model relates to a kind of combination extension bar type water supplying apparatus, belongs to pneumatic water supplying apparatus; Be mainly used in the drilling construction of section of medium-length hole side eye under the coal mine.
Background technology
Mine pneumatic jumbolter and pneumatic side jumbolter are the basic tools of jewel hole under the coal mine, jumbolter cooperates combination six rib drilling rods can carry out at the top jewel hole, the eye that bores when cooperating sectional rod is dark large, maximum can reach 30m, especially be adapted to jewel hole in rock mass, pneumatic side jumbolter cooperation twist drill rods can be at the roadway's sides jewel hole, and general drilling depth is about 2m.
As shown in Figure 1, when pneumatic side jumbolter cooperates twist drill rods, because use is twist drill rods, and twist drill rods can not be used in combination (joining between drilling rod and the drilling rod), thereby hole depth is shallow, and maximum can reach 3.0m, and jewel hole is comparatively difficult in rock mass, and speed is slow.The twist drill rods jewel hole is arranged again, and what depositing dust supplied water employing is external side formula way of supplying water, and mine pneumatic jumbolter private water supply is adopted in the water supply of sectional rod depositing dust, and two kinds of drilling rods can't be accomplished mutual usefulness.
Summary of the invention
For the problems referred to above, the utility model provides a kind of combination extension bar type water supplying apparatus,
The utility model is implemented to realize with following technical scheme: a kind of combination extension bar type water supplying apparatus, and it comprises drill bit, the side direction water supplying apparatus; The sidewall of side direction water supplying apparatus is provided with water supply hole, and an end of side direction water supplying apparatus has air supply hole, and the other end of side direction water supplying apparatus is connected with drill bit by the combination extension bar; Described combination extension bar is comprised of with the lengthening extension bar that is fixedly connected with joint joint; The front end of joint is connected with drill bit, and the other end that lengthens extension bar is connected with the side direction water supplying apparatus; In joint and the lengthening extension bar that is fixedly connected with joint, all have water injection hole.
The power drive of adopting is the compressed air in underground work place, supplies water to be the feedwater of down-hole supply channel, and it is sufficient large to supply water, and drilling depth is large.
The utility model produces effect and is:
1, owing to adopt combined drill rod to transform link, water injection hole is larger than traditional fried dough twist formula drilling rod mesopore, so output is large.
2, connector is short and small, and is simple and quick.
3, speed is fast during perforating, and eye is dark large, and maximum can reach 30m, is applicable to rig in the rock mass, can carry out easily coal mine test discharge water eye, geological drilling and the construction of coal-bed flooding eye.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the prior art structure chart.
Fig. 2 is the utility model structure chart.
Among the figure: 1, drill bit; 2, joint; 3, lengthen extension bar; 4, side direction water supplying apparatus; 5, air supply hole; 6, water supply hole; 7, water injection hole.
The specific embodiment
As shown in Figure 2, combination extension bar type water supplying apparatus, it comprises drill bit 1, side direction water supplying apparatus 4; The sidewall of side direction water supplying apparatus 4 is provided with water supply hole 6, and an end of side direction water supplying apparatus 4 has air supply hole 5, and the other end of side direction water supplying apparatus 4 is connected with drill bit 1 by the combination extension bar; Described combination extension bar is comprised of with the lengthening extension bar 3 that is fixedly connected with joint 2 joint 2; The front end of joint 2 is connected with drill bit 1, and the other end that lengthens extension bar 3 is connected with side direction water supplying apparatus 4; Joint 2 with lengthening extension bar 3 that joint 2 is fixedly connected with in all have water injection hole 7.
In the present embodiment, joint 2 passes through screw thread together with lengthening extension bar 3.The front end of joint 2 have with drill bit 1 extension bar on the internal thread hole of threaded engagement, drill bit 1 is threaded connection with joint 2.The other end that lengthens extension bar 3 is threaded with side direction water supplying apparatus 4.
Specifically doing method is:
1, first employed drill bit 1 is connected with joint 2.
2, be connected together with lengthening extension bar 3 again.
3, the back is connected with improved combined type lengthening extension bar drilling rod.
4, the side direction water supplying apparatus is linked to each other with lengthening extension bar drilling rod.
5, above step complete after, cooperate pneumatic side jumbolter to use, according to the box-like lengthening extension bar of the continuous contiguous sets of drilling depth drilling rod.
