Abstract
The utility model provides a release hole drilling equipment, belongs to colliery tunnelling construction technical field, can solve the problem that current release hole drilling rod loses the drilling rod easily or the speed of punching is slow, including drilling rod and drill bit, the one end of drilling rod is connected with the one end of drill bit, the surface of drilling rod is equipped with along the rotatory screw thread of drilling rod, the drill bit includes the spliced pole, and the top of spliced pole is equipped with the point of drill, and the terminal surface of point of drill is the slope form, and the lateral wall of spliced pole is equipped with a plurality of layers of brill sword, and the quantity of every layer of brill sword is three, and the brill sword on every layer uses the centre of a circle of spliced pole to be equidistant circumference as the center and arranges, and the edge of. Through using the utility model discloses obviously shorten the time of construction release hole, improved the efficiency of punching, saved effective production time for the tunnelling working face, indirectly increased economic benefits.
Description
Technical Field
The utility model belongs to the technical field of the colliery is tunneled and is under construction, concretely relates to release hole drill bit.
Background
All heading faces near a coal mine well region almost face the current situation of construction release holes every day, and drill rods and matched drill bits used for the construction release holes of the underground heading faces are of two types: one is a threaded drill rod and a drill bit matched with the threaded drill rod, and the other is a hexagonal drill rod and a drill bit matched with the hexagonal drill rod. In the actual production process, the six-edge drill rod is used for high drilling speed, but the drill rod is easy to lose after abnormal conditions occur in the drilling process. And the threaded drill rod is firmer because of the threaded connection between the drill rods, the drill rod cannot be lost in the drilling process, but the drilling speed is slower because the drill rod has unsmooth chip removal.
Disclosure of Invention
The utility model discloses to the problem that current release hole drilling rod lost the drilling rod easily or punch slowly, provide a release hole drilling equipment.
The utility model adopts the following technical scheme:
the utility model provides a release hole drilling equipment, includes drilling rod and drill bit, and the one end of drilling rod is connected with the one end of drill bit, the surface of drilling rod is equipped with along the rotatory screw thread of drilling rod, the drill bit includes the spliced pole, and the top of spliced pole is equipped with the drill point, and the terminal surface of drill point is the slope form, and the lateral wall of spliced pole is equipped with a plurality of layers of brill sword, and the quantity of every layer of brill sword is three, and the brill sword on every layer uses the centre of a circle of spliced pole to be equidistant circumference as the center and arranges, and the edge of every layer of brill sword is located same straight line.
The threads are equally spaced.
The length of the drill rod is 0.3-0.5 m.
The cross section of the drill point is U-shaped.
The layers of drill cutters are arranged at equal intervals.
The utility model has the advantages as follows:
1. the improved material of the drill bit for the pressure relief hole of the outburst-prevention working face is convenient to obtain, and the manufacturing process is simple.
2. The time of constructing the pressure relief hole is obviously shortened, the punching efficiency is improved, the effective production time is saved for the driving face, and the economic benefit is indirectly increased.
3. The improved pressure relief hole drill bit is firm and reliable in the using process, the condition that a drill rod is lost in the construction pressure relief hole process is avoided, the waste of the drill rod of the pressure relief hole in the team tunneling process is reduced, and therefore economic benefits are increased for production.
Drawings
Fig. 1 is a schematic structural view of the present invention;
wherein: 1-a drill rod; 2-thread; 3-connecting a column; 4-drilling a tip; 5-drilling a cutter.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in the figure, a release hole drilling equipment, including drilling rod 1 and drill bit, the one end of drilling rod 1 is connected with the one end of drill bit, the surface of drilling rod 1 is equipped with along the rotatory screw thread 2 of drilling rod, the drill bit includes spliced pole 3, and the top of spliced pole 3 is equipped with drill point 4, and the terminal surface of drill point 4 is the slope form, and the lateral wall of spliced pole 3 is equipped with a plurality of layers of brill sword 5, and the quantity of every layer of brill sword 5 is three, and every layer of brill sword 5 uses the centre of a circle of spliced pole 3 to be equidistant circumference as the center and arranges, and the edge of every layer of brill sword 5 is located same straight line, the slope form is.
The threads 2 are arranged at equal intervals.
The length of the drill rod 1 is 0.3-0.5 m.
The cross section of the drill tip 4 is U-shaped.
The layers of drill bits 5 are arranged at equal intervals.
The utility model discloses in, through the long threaded drill rod of an intercepting 0.3-0.5m, weld the drill bit of former hexagonal drilling rod on the threaded drill rod, process into a new threaded drill rod drill bit, not only the speed of punching is fast when constructing the pressure relief vent like this, the condition of losing the drilling rod because of the coal body gas content is unusual can not appear in the in-process of punching moreover.
