Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of hydraulic breaking hammer change-over valve assembly apparatus,
Including quartering hammer main body 11, valve pocket 1, reversal valve 2 and bonnet 3, the inside of quartering hammer main body 11 is provided with piston 10, and the lower end of piston 10 is set
There is drill steel 14, the side of piston 10 is provided with valve pocket 1, and the one end of valve pocket 1 is provided with bonnet 3, and the inside of valve pocket 1 is provided with reversal valve 2, reversal valve 2
Side is provided with oil back chamber 12 and valve element control chamber 13, and valve element control chamber 13 is located at the side of oil back chamber 12, and the opposite side of reversal valve 2 is provided with
Dynamic oil pressure hole 4, high pressure oil hole 5, low pressure oil hole 6, dynamic high-pressure oilhole 7 and dynamic oil pressure hole 8, dynamic high-pressure oilhole 7 are set
There are several, high pressure oil hole 5 is located at the side of dynamic oil pressure hole 4, and low pressure oil hole 6 is located at the side of high pressure oil hole 5, some dynamic high-pressures
Oilhole 7 is located at the side of low pressure oil hole 6, and dynamic oil pressure hole 8 is located at the side of dynamic high-pressure oilhole 7.
In the above-described embodiments, reversal valve 2 includes short valve and long valve.
In the above-described embodiments, the valve element of long valve is longer than the valve element of short valve.
In the above-described embodiments, the one end of piston 10 is provided with signal piston chamber 9.
Concrete principle：Using this kind of hydraulic breaking hammer change-over valve assembly apparatus, backhaul braking motion, piston 10 is in hydraulic oil
In the presence of move upwards, when the stage casing downside of piston 10 cross control mouth it is following when, 10 signal port is opened on piston, is led to
Cross signal piston chamber 9 to start to supply pressure oil toward in valve element control chamber 13, piston 10 is continued up to stop motion, now acted on
The hydraulic coupling of main valve plug is more than the hydraulic coupling that chamber acts on main valve plug, so as to force valve element to start commutation motion, the valve of reversal valve 2
Core action commutates to the right, and pressure oil enters the upper loopback oil pocket 12 of piston 10；The movement of valve element, gradually decrease into the height in chamber
Force feed, so that respective action is also gradually reduced in the backhaul thrust on piston 10, and the backhaul that the relative nitrogen compressed applies
Resistance is increasing, and piston 10 is just transferred to the backhaul deboost phase；Piston 10 starts to move downward, and valve element keeps constant, with
While piston 10 moves downward, the signal piston chamber 9 on piston 10 also progressively closes off, after signal piston chamber 9 is closed, valve element control
Chamber decompression processed, valve element are moved to left position from the right side rapidly, and piston 10 moves downward by inertia, and the final drill steel 14 that hits does work, then
Do drawback movement, reciprocation cycle upwards.
This kind of hydraulic breaking hammer change-over valve assembly apparatus, structure design is completely compact, by the design of long valve, to valve element knot
Structure is improved, and the valve element of surplus is better than the valve element of shortage of money, and the valve element of conventional shortage of money is lengthened, changes profile, realization is changed
To the function of the not card valve of valve 2, reversal valve 2 is between valve pocket 1 and bonnet 3 with reciprocating motion of the pistons, when 10 stroke of piston, commutation
Valve 2 is in hyperbaric environment and jacked up always, and when oil back chamber 12 is passed through at the middle part of piston 10, the hyperbaric environment of reversal valve 2 occurs
Change, high pressure are changed into low pressure, and reversal valve 2 starts to commutate, and reversal valve 2 and bonnet 3 and the relative position of valve pocket 1 change, and make
Whole process is obtained without card valve phenomenon, stability is added, improves the sensitivity of reversal valve 2, significantly reduce oil temperature, significantly
The mechanical efficiency of hydraulic breaking hammer is improved, mechanical parts and seal requirement is reduced, increases the service life, save the energy of preciousness
Source, the utility model is simple in construction and reasonable in design, more hommization, is adapted to promote the use of.
