Abstract
The utility model discloses a multifunctional bit shank sleeve, and the multifunctional bit shank sleeve comprises a bit shank connecting rod and a connector; a fixing clamp is arranged on one side of the lower part of the bit shank connecting rod while the connector is arranged at the upper part of the bit shank connecting rod; a hexagonal cylindrical cavity and a spiral bayonet are drilled in the connector in turn, and a spiral slot is drilled along the inner wall of the spiral bayonet. The construction for different gasproof drillings, anchor ropes and anchor rods can be realized without exchanging a drilling machine and repeatedly connecting a pipeline; multipurpose is achieved, mutual effect in the field construction is reduced, and cost of construction is saved; the multifunctional bit shank sleeve has characteristics such as simple structure, convenience for portability and usage, multiple purposes, etc..
Description
Technical field
The utility model relates to a kind of mining-drilling machine parts, especially a kind of can with ZQS-65,80, the matching used multi-functional bit shank cover of 100/2.5 Pneumatic hand rig.
Background technology
ZQS-65,80,100/2.5 Pneumatic hand rig are the maximum hand-held pneumatic rigs of rated power in the market; Advantage is apparent in view when the hard protrusion-dispelling hole of drilling deep hole or ature of coal; It is high, easy to use in the coal seam, to creep into nearly horizontal drilling efficient, is fit to very much accomplish fast the construction of all kinds of anti-gas borings.But in the coal road construction of conventional bolting with wire mesh, need utilize the MQS-45/1.4C2 rig, armature boring and the anchor cable boring of constructing; Need utilize all kinds of anti-gas borings of constructing of ZQS-65,80,100/2.5 Pneumatic hand rig.Like this, when the coal road construction of bolting with wire mesh, need change rig, connecting line continually, cause the anti-gas boring of construction to influence each other, reduce whole roadway construction efficient with the tunnelling construction drill.
The utility model content
The purpose of the utility model provides a kind ofly need not change rig, and connecting line can be realized the multi-functional bit shank cover to all kinds of anti-gas borings, anchor cable boring, armature boring construction again.
To achieve these goals; The utility model comprises: bit shank connecting rod, connector; One side is provided with fixed card in the bottom of bit shank connecting rod; Top at the bit shank connecting rod is provided with connector, in connector, has interior six a sides chamber and spiral bayonet socket successively, has helicla flute along spiral bayonet socket inwall.
Like this, utilize all kinds of anti-gas borings of can constructing of ZQS-65,80,100/2.5 Pneumatic hand rig.When needs constructions anchor cable or armature boring, take down drill bit, bit shank connecting rod and ZQS-65,80, the 100/2.5 Pneumatic hand rig of the utility model is connected.Then through the spiral bayonet socket can with the little coal borer bar of φ 27-43 rapid abutting joint construction armature boring; Also can need not change rig, again connecting line through interior six a sides chamber and the boring of B19 anchor cable drilling rod construction anchor cable; Can realize construction to all kinds of anti-gas borings, anchor cable, anchor pole; A tractor serves several purposes has reduced influencing each other of site operation, has practiced thrift construction cost.Have simple in structurely, be easy to carry, easy to use, characteristics such as a tractor serves several purposes.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Can know that by Fig. 1 the utility model comprises: bit shank connecting rod 2, connector 3.A side is provided with fixed card 1 in the bottom of bit shank connecting rod 2, is used for guaranteeing that its secure is reliable when the bit shank connecting rod is connected with ZQS-65,80,100/2.5 Pneumatic hand rig.Be provided with connector 3 on the top of bit shank connecting rod 2, in connector, have interior six a sides chamber 6 and spiral bayonet socket 5 from top to bottom successively, have helicla flute 4 along spiral bayonet socket inwall.Spiral bayonet socket and the little coal borer bar of φ 27-43 size shape are mated each other, and interior six a sides chamber and B19 anchor cable drilling rod size shape are mated each other.The utility model should adopt high-quality Corrosion-proof steel products processing and fabricating, to guarantee its mechanical strength and decay resistance, satisfies requirement under the coal mine.
