Fig. 1 is the structural representation of the utility model.
Among the figure, 1, front-bank rotor housing 2, middle cylinder body; 21, groove 3, rear-bank rotor housing 4, piston 5, drill steel 6, loam cake 7, lower cover 71, link 8, barrier film 9, upper chamber 10, lower chambers; 11, first sealing ring; 12, second sealing ring 13, charge valve.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; The small-sized quartering hammer of this band supercharging device comprises cylinder body, is positioned at the piston 4 and the drill steel 5 of cylinder body; Cylinder body comprises front-bank rotor housing 1, middle cylinder body 2 and rear-bank rotor housing 3; Wherein front-bank rotor housing 1, middle cylinder body 2 and rear-bank rotor housing 3 are fixed together through many bolts, the inside of cylinder body 2 during piston 4 is installed in, drill steel 5 be positioned at front-bank rotor housing 1 inner and be positioned at piston 4 under.
On middle cylinder body 2, accumulator is installed; Accumulator comprises the loam cake 6 and lower cover 7 that is fixed together through bolt; Be formed with chamber and chamber between loam cake 6 and the lower cover 7 and become upper chamber 9 and lower chambers 10 through barrier film 8 sealed separation, wherein lower chambers 10 communicates with middle cylinder body 2 inner chambers.During lower cover 7 is fixed on through a plurality of high-strength bolts on the cylinder body 2, like this can with lower cover 7 firm are fixed on the cylinder body 2, thereby guarantee the connection reliability between accumulator and the middle cylinder body 2.Barrier film 8 adopts the hydrogenated nitrile-butadiene rubber material to process, and owing to being high saturated rubber with hydrogenated nitrile-butadiene rubber, it does not change high resiliency and sealing in the dense oil dense solvent midium or long term, thereby can guarantee the sealing performance between upper chamber 9 and the lower chambers 10.
On middle cylinder body 2 sidewalls, offer groove 21, lower cover 7 has link 71 and link 71 fixes in groove 21, on the cylinder body 2, makes lower chambers 10 aim at accurately with middle cylinder body 2 inner chambers and is communicated with in can easily and accurately accumulator being installed to like this.Between middle cylinder body 2 grooves 21 and lower cover 7 links 71, first sealing ring 11 is installed, the hydraulic oil in can preventing like this in cylinder body 2 inner chambers leaks into the external world.Between middle cylinder body 2 outer walls and lower cover 7, second sealing ring 12 is installed, the sealing performance in can further strengthening like this between cylinder body 2 and the accumulator.Charge valve 13 is installed on loam cake 6,, can nitrogen be filled in the upper chamber 9, close charge valve 13 and can prevent that nitrogen from going out from upper chamber's 9 internal leakages through opening charge valve 13.
This quartering hammer utilizes the pressure differential of hydraulic oil in the cylinder body to promote impact piston 4 and moves, thereby impacts the purpose that drill steel 5 reaches broken object.Through charge valve 13 nitrogen is filled in the accumulator upper chamber 9 earlier before using; When piston 4 is positioned at the inner chamber of cylinder block rear end; Hydraulic oil in the inner chamber is the highest with barrier film 8 jack-up; Accumulator inner septum 8 upper spaces are minimum, that is to say that the nitrogen pressure in the upper chamber 9 is maximum, and this moment, the energy of accumulator institute Chu was also maximum.When the hydraulic oil release, pressure that accumulator stores up discharges, and the compression face on the fierce impact piston of hydraulic oil 4 tops makes piston 4 impact drill steel 5 upper surfaces rapidly downwards, reaches the purpose of broken object.This device possesses supercharging and buffering function simultaneously; So it is a lot of that the variation of oil pressure reduces than common no-load voltage ratio ordinary construction; Can improve this quartering hammer hitting power of piston 4 in use through increasing accumulator, satisfy the needs of quartering hammer operation under special operation condition, system oil return pressure is steady in use simultaneously; Greatly reduce the oil pipe degree of jitter, protected the big pump of digging machine effectively.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
