Abstract
The utility model relates to a special fitting for a rock drift hydraulic drill rig, particularly a special fine drill for a hydraulic drill rig and the special fine drill for a hydraulic drill rig can punch bolt holes of which the diameter is 32 mm. The utility model is composed of a drill rod and a drill head, wherein the drill head is connected with the drill rod; the drill rod is a hollow hexagonal steel rod body, the tail part is connected with a connecting sleeve of a shank of the hydraulic drill rig, and the front part is connected with the drill head; the drill head is in a cast tooth shape. Compared with an air drill, the speed of the utility model for punching the bolt holes is raised by 3 times and personnel are saved by 2 times. After the hydraulic drill rig is provided with the special fine drill, the hydraulic drill rig can be used for drilling blastholes in three light blasting and the construction progress can be enhanced. In addition, the utility model has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of special part of rock gangway hydraulic drill rig, particularly relates to a kind of special-purpose jig drill tool of hydraulic drill rig that can beat diameter 32mm square.
Background technology
The stone head hydraulic drill rig is the special equipment of perforating in the rock construction, and speed is fast during perforating, quality good.But drill bit that uses because of hydraulic drill rig and drill pipe diameter and gunpowder powder stick are complementary (bit diameter 42mm, drill pipe diameter 32mm).When using mechanical anchor poles such as cement-roll anchor pole, piston ring type, square is identical with borehole diameter in the past, and hydraulic drill rig can promptly be beaten work plane borehole square again.High-strength deformed steel bar anchor pole, the extensive use of resin volume in recent years, and replaced mechanical anchor poles such as the cement-roll anchor pole that in the past used, piston ring type.The diameter of these squares is thin than borehole, is generally 28-32mm.Because material and production technology are limit, never manufacturer production is beaten drilling rod, the drill bit of the hydraulic drill rig special use of this diameter square.This just makes hydraulic drill rig can only beat the work plane borehole, can't beat square.Can only use air drill to join target drill in the construction and beat square, square speed is slow, efficient is low, labor strength is big, working security is poor and air drill is beaten.
Summary of the invention
The purpose of this utility model provides a kind ofly can beat the special-purpose jig drill tool of hydraulic drill rig that diameter is the 32mm square with hydraulic drill rig.After hydraulic drill rig disposes this accessory, can beat the work plane borehole and can beat square again, not only can alleviate working strength of workers, and handling safety.
The technical scheme that realizes the foregoing invention purpose is: be made up of with the drill bit that is connected with drilling rod drilling rod.Described drilling rod is the hollow hexagonal steel body of rod, and its afterbody is connected with the adapter sleeve of hydraulic drill rig bit shank, and drill bit is connected with drilling rod for the casting flute profile.The utility model used on 3 hydraulic drill rigs of the Luan Qian Jiaying that opens a mine in June in this year, and construction tunnel was more than 600 meter in two months, beat more than 5000 of diameter 32mm squares, beat more than 10000 meter of square length, and result of use is good.The speed of beating square is than using air drill to improve 3 times (use air drill to make a call to 2 meters dark squares in 6 minutes, use the utility model only to use 2 minutes).Personnel are than using air drill to save 2 times.The borehole that after hydraulic drill rig assembles this brill, also can be used in " three light shots " creeps into, and can greatly improve construction speed.In addition, this apparatus structure is simple, processing ease.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is a jackrod structure schematic diagram of the present utility model.
Fig. 3 is a drill bit structure schematic diagram of the present utility model.Form Fig. 3-the 1st wherein, front view by Fig. 3-1,3-2,3-3.Fig. 3-the 2nd, sectional view.Fig. 3-the 3rd, vertical view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.The utility model is made up of drilling rod, drill bit.The main body 5 of its drilling rod 2 is a B25 hexagonal cored steel structure, carries out the transition to drill bit linkage section 1 and is 22R * 12.7 left-hand threads, and the setting of left-hand thread guarantees that drilling rod and drill bit link together securely.Carry out the transition to bit shank linkage section 3 and be 32R * 12.7 left-hand threads, can directly be connected, the working condition that high-frequency, high pulling torque impact rotation when adapting to perforating with hydraulic drill rig bit shank adapter sleeve.Accompanying drawing 3 is embodiment of drill bit 4.Referring to accompanying drawing 3-1,3-2,3-3, drill bit 4 is casting tooth type structures, and 4 teeth 7 are set altogether, and as Fig. 3-3, the distribution of tooth 7 is, one on the top of drill bit 4, and 120 degree are one on the bit body, 3 teeth of spaced set.The afterbody of drill bit such as Fig. 3-2 has and is connected supporting 22R * 12.7 left-hand threads 6 with drilling rod.
During use, the left-hand thread 6 of Fig. 3 twisted mutually with the left-hand thread 1 of Fig. 1 connect, both are one, manipulate very convenient.
Claims (3)
1, the special-purpose jig drill tool of a kind of hydraulic drill rig is made up of with the drill bit that is connected with drilling rod drilling rod, it is characterized in that described drilling rod is the hollow hexagonal steel body of rod, and its afterbody is connected with the adapter sleeve of hydraulic drill rig bit shank, and drill bit is connected with drilling rod for the casting flute profile.
2, the special-purpose jig drill tool of hydraulic drill rig according to claim 1 is characterized in that the afterbody of drilling rod is provided with left hand thread, is threaded with the hydraulic drill rig bit shank.
