Description
Technical field
The utility model belongs to borehole drilling technique more particularly to a kind of chambering device structure in coal mine.
Background technology
With the development of geotechnical engineering, more and more requirement of engineering are used drilling and are carried out in explosion or extraction Rock And Soil
Dangerous pernicious gas.But need to carry out the expansion in aperture in engineering practice in certain bore position, and general drilling
Equipment can not realize this function, cause to carry out to carry out ream operation in the specific position of drilling.
Utility model content：
The technical problems to be solved in the utility model：A kind of chambering device structure is provided, to solve the brill of the prior art
Hole equipment cannot carry out the technical problems such as reaming to drilling specific position.
Technical solutions of the utility model：
A kind of chambering device structure, it includes outer tube；One end of outer tube is fixedly connected with drilling machine, the other end and cross
Shape bore bit is fixedly connected；Outer tube offers two symmetrical rectangular slots on the caliber of bull bit connecting pin；Outer tube
It is inside fixed with jack, the lift side of jack is directed toward bull bit, is fixed with connecting rod on the lift side of jack, connects
The both ends of bar are located in two symmetrical rectangular slots, and wedge type block is fixed on the both ends of connecting rod, is consolidated on wedge type block
Surely there is a down-the-hole bore bit, the position of wedge type block and down-the-hole hole bore bit is corresponding with the groove of bull bit.
The handle of jack stretches out outside outer tube.
Outer tube bull bit and drilling machine are connected through a screw thread.
The beneficial effects of the utility model：
Outer tube one end of the reamer of the utility model is fixedly connected with drilling machine by the utility model, the other end is solid
Surely bull bit is connected；By operating the handle of jack, the lift side of jack starts to stretch out, and drives the connection of lift side
Bar moves in two rectangular slots of outer tube, and wedge type block and down-the-hole hole bore bit are inserted into the groove of bull bit,
Carry out expansion reaming；The utility model is simple in structure, easy to use；The drilling device for solving the prior art cannot be special to drilling
Positioning, which is set, carries out the technical problems such as reaming.
Description of the drawings：
Fig. 1 the utility model structure diagrams；
Fig. 2 is the utility model bull bit structural schematic diagram.
Specific implementation mode：
A kind of chambering device structure, it includes outer tube 4, and one end of outer tube 4 is fixedly connected with drilling machine, the other end and ten
Font bore bit 2 is fixedly connected；Outer tube 4 offers two symmetrical rectangular slots on the caliber of 2 connecting pin of bull bit；
It is fixed with jack 1 in outer tube 4, the lift side of jack 1 is directed toward bull bit 2, the company of being fixed on the lift side of jack 1
The both ends of extension bar 7, connecting rod 7 are located in two symmetrical rectangular slots, and wedge type block is hinged on the both ends of connecting rod 7
6, down-the-hole bore bit 5, wedge type block 6 and the position of down-the-hole hole bore bit 5 are fixed on wedge type block 6 and the groove 8 of bull bit 2 is right
It answers.
Jack 1 is fixed in outer tube 4；By being welded and fixed；A bottom plate is welded specially on the tube wall of outer tube 4,
By the tube chamber welds with base of jack 1 on bottom plate.
The handle of jack 1 stretches out outside outer tube 1.
1 bull bit 2 of outer tube and drilling machine are connected through a screw thread.
When reaming, bull bit 2 is reached into reaming position by drilling machine, by operating the handle of jack 1, by wedge
Type block 6 and down-the-hole hole bore bit 5 move forward, since the both ends sampling of 6 connecting rod 7 of wedge type block is hinged；Wedge type block 6 and down-the-hole hole bore bit 5
When Forward is contacted with groove 8, wedge type block 6 can go up lift, and expansion reaming can be carried out by being inserted into the groove 8 of bull bit 2；Reaming
After, the handle of jack 1 is operated, the telescopic end of jack 1 is withdrawn, is moved after making wedge type block 6 and down-the-hole hole bore bit 5；It is de-
Groove 8 from bull bit 2；It carries out continuing to drill.
