Embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit protection model of the present utility model
Enclose.
, it is necessary to explanation, term " on ", " under ", "left", "right", " interior ", " outer " etc. in description of the present utility model
The orientation or position relationship of instruction are based on orientation shown in the drawings or position relationship, are for only for ease of description the utility model
Described with simplifying, rather than the device or element of instruction or hint meaning there must be specific orientation, with specific orientation structure
Make and operate, therefore it is not intended that to limitation of the present utility model.
Referring to Fig. 1-2, the utility model provides a kind of technical scheme, a kind of novel hydraulic crushing hammer reversing valve complement,
Including breaking hammer main body 1, valve pocket 2, reversal valve 3 and bonnet 4 are provided with described breaking hammer main body 1, one end of wherein valve pocket 2 is set
There is bonnet 4, and reversal valve 3 is provided with valve pocket 2, the side of reversal valve 3 is sequentially provided with dynamic oil pressure hole 5, high pressure oil hole 6, low pressure
Oilhole 7, dynamic high-pressure oilhole 8 and dynamic oil pressure hole 5, the opposite side of reversal valve 3 are provided with oil back chamber 9 and valve element control chamber 10.
Wherein, in the present embodiment, described high pressure oil hole 6 is provided close to the side of bonnet 4.
Wherein, in the present embodiment, described valve element control chamber 10 is provided close to the side of bonnet 4.
Wherein, in the present embodiment, described reversal valve 3 includes short valve and long valve, wherein short valve element is provided with short valve, it is long
Long valve element is provided with valve, and the length of short valve element is less than the length of long valve element.
Wherein, in the present embodiment, the quantity of described dynamic high-pressure oilhole 8 is several.
Operation principle of the present utility model：It is living using this kind of hydraulic breaking hammer change-over valve assembly apparatus, backhaul braking motion
The effect filled in hydraulic oil is moved from bottom to top, supplies pressure oil when reaching certain position into valve element control chamber 10, and piston continues
Stop motion is upwardly into, the hydraulic coupling for now acting on reversal valve 3 is more than the hydraulic coupling that valve element control chamber 10 acts on main valve plug,
So as to force valve element to start commutation motion, the valve element action of reversal valve 3 commutates to the right, and pressure oil enters oil back chamber 9；Reversal valve 3
Movement, gradually decrease into the hydraulic oil in valve element control chamber 10, thus respective action in the backhaul thrust on piston also by
It is decrescence small, and the backhaul resistance that the relative nitrogen compressed applies is increasing, piston is just transferred to the backhaul deboost phase；Piston
Starting to move downward, reversal valve 3 keeps constant, while being moved downward with piston, valve element control when piston reaches certain position
The decompression of chamber 10 processed, reversal valve 3 are moved to left position from the right side rapidly, and piston moves downward by inertia, and the final drill steel that hits does work, then
Do drawback movement, reciprocation cycle upwards.
By the design of long valve, valve core structure is improved, the valve element of surplus is better than the valve element of shortage of money, will be in the past short
The valve element of money lengthens, and changes profile, realizes the function of the not card valve of reversal valve 2, reversal valve 3 is between valve pocket 2 and bonnet 4 with work
Plug moves back and forth.When piston stroke, reversal valve 3 is in hyperbaric environment and jacked up always, passes through oil back chamber 9 in the middle part of piston
When, the hyperbaric environment of reversal valve 3 changes, and high pressure is changed into low pressure, and reversal valve 3 starts to commutate, reversal valve 3 and bonnet 4 and
The relative position of valve pocket 2 changes, and whole process adds stability, improve the sensitivity of reversal valve, have without card valve phenomenon
Oil temperature is reduced to effect, substantially increases the mechanical efficiency of hydraulic breaking hammer, reduces mechanical parts and seal requirement, extension makes
With the life-span, the valuable energy is saved.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
