Description
Technical field
The invention belongs to engineering machinery fields, and in particular to a kind of use is in mining, highway, railway, water conservancy, tunnel
New hydraulic drill torque output structure in construction project.
Background technology
At present in China's mining, high ferro, subway tunnel, water conservancy construction, gas leg type air drill is largely used,
For annual requirement at 100,000 or more, practitioner reaches more than 350,000.The advantages of air drill is：It is simple in structure, price is low,
Sealing requirements are not that very stringent, Maintenance Specialty is not strong.Shortcoming is that capacity usage ratio is low, and vibration is big, noise is high, and there is oil
Gas pollution problem threatens the physical and mental health of miner.
Hydraulic drill is a kind of energy saving, environmentally friendly rock drill.Its main feature is that：Cutting rate is fast, low noise, oil-free
Mist pollutes, is with small vibration, energy saving.
The operation principle of water rock drill is：Using high pressure water as power, reciprocating motion of the pistons, punching are controlled by matching somebody with somebody flow control valve
Cheng Shi, piston impact drill steel and bore bit chisel crushed rocks；When independent swing mechanism or backward stroke of the piston, drill steel and bore bit revolution are driven
Certain angle.Continuous impact, revolution make drill steel and bore bit dig out circular blasthole on rock.Drive drill steel and bore bit revolution
Torque output part be hydraulic drill hexagonal hole axis, the hexahedron of drill steel is just inserted in the hexagonal hole of hexagonal hole axis.The two
Between fit clearance it is bigger, generally in 0.5mm or so.From the point of view of from for many years, either hydraulic drill or gas
Dynamic rock drill drives the leading portion of the hexagonal hole of drill steel rotation（About length is in the range of 50mm）It is most easy to wear to become larger, and then produce
It is raw：Rock drill rocks increase, and the bit shank of drill steel easily snaps off.At this moment would have to replace hexagonal hole part in time.
But installation replacement hexagonal hole part is cumbersome, especially the hexagonal hole axis of hydraulic drill is replaced more troublesome,
On gear is installed, the requirement on machining accuracy of axis is high, but also to process keyway, and the cost of hexagonal hole axis is still higher.
Simply because entire axis is replaced in the abrasion at hexagonal hole axis leading portion about 50mm, the waste and replacement of resource are caused
Inconvenience.
The content of the invention
The technical problem to be solved by the present invention is to overcome the above-mentioned deficiency of the prior art, provide a kind of not only cost-effective but also just
In the new hydraulic drill torque output structure of replacement.
To solve the above-mentioned problems, the present invention uses following technical scheme：A kind of new hydraulic drill torque is defeated
Go out structure, including drill steel, hexagonal hole axis is coaxially equipped on drill steel, before the position of close end is leaned on coaxially to be equipped on hexagonal hole axis
Body is provided with six square sets being conveniently replaceable in precursor close to the position of hexagonal hole shaft end.
It is further optimization of the present invention to said program below：Six square set and one end of hexagonal hole axis are coaxially removable
Unload assembling.
Further optimization：Circular array is shown in multiple six square sets on the end face of hexagonal hole axis in six square set
Hole.
Further optimization：On the hexagonal hole axis close to six square sets end face on circular array show it is multiple respectively with six sides
The hole on hexagonal hole axis that hole is used cooperatively on set.
Further optimization：Pass through cylinder pin connection between hole on the hexagonal hole axis and the hole in corresponding six square set.
Further optimization：The length of six square set along own axes is 45-60mm.
By flat key hexagonal hole axis is driven to rotate in use, gear is rotated, hexagonal hole axis drives six square sets by straight pin
Rotation thus drives drill steel and the rotation of the bore bit on drill steel head, so as to dig out hole, when the hexagonal hole abrasion of six square sets is big
When, the circlip for hole on precursor is removed, six square sets can be removed replacement from hexagonal hole axis.
The present invention replaces present invention repair more convenient, had both reduced repair by setting six square sets being conveniently replaceable
When workload, save maintenance time, and reduce the volume for needing replacing component, save material more than 75%, reduce use
The 80% of family use cost.
The invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
Embodiment, as shown in Figure 1 to Figure 3, a kind of new hydraulic drill torque output structure, including drill steel 14,
Coaxially it is equipped with hexagonal hole axis 9 on drill steel 14, the position on hexagonal hole axis 9 by close end is coaxially equipped with precursor 1, in precursor 1
The position of 9 end of hexagonal hole axis is provided with six square sets 10 being conveniently replaceable.
Six square set 10 and one end of hexagonal hole axis 9 are coaxially detachably assembled, and are offered and can be accommodated in six square sets 10
The hexagonal hole of drill steel 14, so design are not only conveniently replaceable but also save cost.
Six square set 10 is 45-60mm along the length of own axes, and so design is more advantageous to saving material and expense,
Reduce unnecessary waste.
Circular array shows the hole A in multiple six square sets on the end face of hexagonal hole axis 9 in six square set 10.
On the hexagonal hole axis 9 close to six square sets 10 end face on circular array show it is multiple respectively with the hole in six square sets
The hole B on hexagonal hole axis that A is used cooperatively.
It is connected between hole B on the hexagonal hole axis and the hole A in corresponding six square set by straight pin 2, and straight pin 2
Coordinate respectively with the hole A transition on the hole B on hexagonal hole axis and corresponding six square set, so design was not only convenient for assembly, but also reduced
Assembling volume.
Position in the precursor 1 close to six square sets, 10 one end is provided with to prevent six square sets 10 from axial float occur
Circlip for hole 11.
On the hexagonal hole axis 9 transition disc 3, and transition disc 3 and precursor 1 are coaxially equipped with close to the position of 1 one end of precursor
It is detachably assembled by multiple hexagon socket head cap screws 12.
The hexagonal hole axis 9 is rotatablely connected with transition disc 3 by second bearing 8, and one end of transition disc 3 is also by interior hexagonal
Geared sleeve 4 is bolted, and geared sleeve 4 is rotatablely connected by clutch shaft bearing 6 and hexagonal hole axis 9.
Gear 5 is coaxially equipped with by flat key 7 on the geared sleeve 4, and gear 5 is located in geared sleeve 4.
Position on the hexagonal hole axis 9 close to 5 one end of gear is provided with circlip for shaft 13, circlip for shaft 13
For the axial float of limiting gear 5.
By flat key 7 hexagonal hole axis 9 is driven to rotate in use, gear 5 is rotated, hexagonal hole axis 9 is driven by straight pin 2
Six square sets 10 rotate, and drill steel 14 and the rotation of the bore bit on drill steel head are thus driven, so as to dig out hole, as six sides of six square sets 10
When hole has been worn big, the circlip for hole 11 on precursor 1 is removed, it can be by six square sets 10 from hexagonal hole axis 9
Remove replacement.
The present invention replaces present invention repair more convenient, had both reduced repair by setting six square sets being conveniently replaceable
When workload, save maintenance time, and reduce the volume for needing replacing component, save material more than 75%, reduce use
The 80% of family use cost.
