Description
Technical field
The present invention relates to heavy-duty machinery technical field, more particularly to a kind of rock drill, in particular to a kind of new structure
Energy saving method for rock machine.
Background technology
It is well known that the operation principle of rock drill is：Using the compressed air of air compressor machine output as power, by with flow control
Valve controls reciprocating motion of the pistons, during stroke, piston impact drill steel and bore bit chisel crushed rocks；During backhaul, piston driving drill steel and pricker
Head turns round certain angle.Continuous impact, revolution make drill steel and bore bit dig out circular blasthole on rock.
The reciprocating impact of rock drill, revolution are to cooperate to what is realized by the cylinder body with flow control valve and rock drill.
The compressed air of external world's access enters matching somebody with somebody in chute in the valve cabinet with flow control valve by dedicated channel.When with flow control valve
Valve element to the relative direction that is worked with rock drill move when, be turned on the compressed air in chute, by with flow control
The back cavity that the axial hole set on the bonnet of valve enters cylinder body of rock drill promotes piston Impact Rock Drilling Rod forward；When piston to
During preceding impact energy transmission is to drill rod, the rear end face of piston crosses the exhaust outlet of cylinder body of rock drill, so as to promote
The pressure of the compressed air of piston preshoot is kept to rapidly zero, and piston does retarded motion.At this moment the back pressure of cylinder body ante-chamber gradually increases,
Pressurized air is pushed away the valve element with flow control valve to the direction that rock drill moves by designated lane, so as to cut off with chute
Middle compressed air enters the passage of cylinder body of rock drill back cavity, and the compressed air matched somebody with somebody during the cut-out in chute enters flow
Special radial hole road in the valve cabinet of control valve, then by the special duct on cylinder body enter cylinder body ante-chamber promote piston after move
Drawback movement is realized, piston driving rotating mechanism is together with the one piece of rotation of drill steel and drill bit during backhaul.In backward stroke of the piston
During, when the exhaust outlet of piston nose face and cylinder body is connected, promote the compressed air pressure moved after piston to be just kept to zero,
Backward stroke of the piston is slowed down.The back pressure of cylinder body back cavity gradually increases in moderating process, and pressurized air is just entered by special duct
Entering to the special duct of valve cabinet with flow control valve promotes valve element to enter cylinder body with rock drill work relative direction movement opening again
The passage of back cavity, piston is promoted to do stroke movement again, stroke terminates and is backhaul.Piston is exactly with flow control valve and cylinder body
Mutual cooperation in realize motion, so as to having dug out hole in rock.
Current rock drill is realize the control structure of reciprocating motion of the pistons function the characteristics of：
1. it is provided with five radial holes of different sizes in the valve cabinet with flow control valve；
2. four functional holes for being used for valve element commutation are provided with the bonnet with flow control valve；
3. flat valve complicated integral structure, mutual mating surface is more, and processed complex efficiency is low.
4. housing structure is also complicated, there is provided 6 radial holes to realize the function of flat valve, process trouble, efficiency
Lowly.
5. this mutual cooperation between flow control valve and cylinder body realizes that piston reciprocating punching, drawback movement will consume one
Partial compression air, does not possess energy saving.
We are directed to this problem expansion research that presently, there are, and make the control unit structure letter for realizing reciprocating motion of the pistons
Dan Hua, difficulty of processing is reduced, improving processing efficiency reduces processing cost, and part energy can be saved during user's use.
The content of the invention
The technical problem to be solved in the present invention is the weak point present in prior art, there is provided a kind of new structure
Energy saving method for rock machine, energy saving method for rock prow of the present invention first changes from structure, compared with traditional structure, letter
It is single, parts machining difficulty is reduced, reduces cost, furthermore with this structure, is adjusted by gas circuit, realizes changing for valve element
To motion, consumption of compressed air does not save more.

Air admission hole 6 of the compressed air through rock drill ratchet, then the hole through valve cabinet 3 enter first with chute 1.4, work as work
Plug 10 and valve 2 are in shown in Fig. 4 during position, and at this moment the stroke of piston 10 will start, when piston 10 makees stroke movement to the left, cylinder
The ante-chamber of body（Piston right chamber）In back pressure increase, gas compressed enters the valve of valve cabinet 3 by gas return path 11
Cabinet radial hole 3.7, compressed air are pushed away to the right valve 2 by the left side of valve 2, and the right side of valve 2 and first end face contact to be formed
Sealing surface, cut-out compressed air enter the passage of cylinder body back cavity.
Compressed air in valve cover cavity is entered in the second axis hole of valve cabinet 3, then valve cabinet radial hole 3.7, cylinder body through valve cabinet 3
Valve cabinet radial hole 3.7 and gas return path enter the ante-chamber of cylinder body（Piston right chamber）In, at this moment compressed air just promotes
Piston 10, piston 10 is set to be moved back action drawback movement.
During piston 10 moves backward when cylinder body ante-chamber communicates with exhaust outlet, compressed air in cylinder body ante-chamber outwards by
Gradually discharge and make retarded motion, because the motion backward of piston 10 makes the back cavity of cylinder body 4 form closed chamber again, the back pressure in back cavity
Gradually increase, the back pressure in bonnet 1 also promotes the right side of valve 2 to be moved to the left valve 2 therewith increasing, when the left side of valve 2
Enter the passage of the ante-chamber of cylinder body 4 with being switched off compressor air during the end contact of valve cabinet 3, at this moment the compressed air in bonnet 1
Hole through bonnet 1, which is entered in the back cavity of cylinder body 4, promotes piston 10 to make stroke movement forward.
With travelling forward for piston 10, when the back cavity of cylinder body 4 is connected with steam vent 13, compressed air in back cavity to
Outer discharge, piston 10 gradually make retarded motion, while the ante-chamber of cylinder body（Piston left chamber）Closed chamber, the back of the body of ante-chamber are formed again
Pressure gradually increase, initially entering designated lane promotion valve 2 again and moving right to cut off to the inlet channel of the back cavity of cylinder body makes cylinder
The ante-chamber of body enters compressed air, and piston 10 starts to make drawback movement.
In a word, the switching of the stroke movement and drawback movement of piston 10 is the relative motion by valve 2 and the supply that is formed
Direction conversion is brought up, and this process consumes substantial amounts of compressed air；Moving right to the left for valve 2 is in cylinder body by piston 10
The motion of front and rear chamber in the back pressure that is formed and promote valve 2 to commutate, the compressed air in air supply system is not consumed during this.
Fig. 4-5 show current rock drill and realizes piston stroke, the structural system figure of drawback movement.Work as external compressed air
Air admission hole through ratchet 12 is entered in valve cabinet through valve cabinet air admission hole, and position shown in Fig. 5 is that the stroke of piston 10 terminates backhaul i.e.
State.
In the above-described embodiments, the preferred forms of the present invention are described, it is obvious that in the invention structure of the present invention
Under think of, many changes can be still made, here, it should be noted that any change made under the inventive concept of the present invention all will
Fall within the scope of protection of the present invention.
