Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As shown in Figure 1, Pneumatic immpacting circulator for Test of rock cracking of the present utility model, comprise housing 4, bit shank 1, air hammer 6 and gas circulator 8, one end of described bit shank 1 is located in housing 4, and described bit shank 1 is connected and High Rotation Speed under the driving of gas rotating device 8 with the output of gas rotating device 8 by transmission component 3; Piston 7 in described air hammer 6 is arranged towards bit shank 1, is used for bit shank 1 to impact.Housing 4 of the present utility model is provided with and impacts adpting flange 5 and the flange 11 that is rotatably connected, utilize impact adpting flange 5 to be directly connected with the air hammer of different operating parameter 6, utilization 11 of the flanges that are rotatably connected can directly be connected with the gas rotating device 8 of different operating parameter, thereby do not change original agent structure and can meet the various parameter needs of Test of rock cracking., realized change and the adjustment of Pneumatic immpacting circulator parameter in a big way, to meet the needs of rock-cracking mechanism research; And adopt same set of agent structure just can complete the test of various different parameters, simplified pilot system, saved experimentation cost.
In the present embodiment, water jacket 2 is set on one end of bit shank 1 on housing 4, for passing through bit shank 1 to rock-boring water filling, to get rid of landwaste, to reduce dust.
In the present embodiment, air hammer 6 is the assembly structure of a replaceable piston 7, and the impact air inlet stop valve 10 of calming the anger outside being placed in piston rod 9 enters piston rod 9 driven plunger 7, and piston 7 is implemented reciprocating impact to bit shank 1 under driving.
In the present embodiment, gas rotating device 8 is air motor, the rotating inlet stop valve 12 of calming the anger outside being placed in gas rotating device 8 enters air motor, by transmission component 3(as gear drive) drive bit shank 1 to rotate, formed the rotary impact effect to rock together with air hammer 6.
As shown in Figure 2, when air hammer 6 is during in impact stroke, piston 7 is in piston rod 9 bottoms, and distributing valve 13, in limes superiors position, is calmed the anger and entered piston rod 9 by the impact air inlet stop valve 10 being placed in outside machine.Enter behind piston rod 9 bottoms, promotion piston 7 moved upward, the gas on piston 7 tops by cylinder body before air flue 16 drain into atmosphere.By the elevating movement of distributing valve 13, realize the direction of piston rod 9 interior air inlets, the lifting of distributing valve 13 is controlled by controlling gas circuit 15.
When piston 7 moves to certain position, while opening out valve air flue 14, distributing valve 13 is displaced downwardly to limit inferior position, and airflow direction changes, and piston 7 only depends on inertia to continue motion forward, impacts after bit shank 1, starts backstroke.In the time that the lateral wall of piston 7 blocks out valve air flue 14, for opening the closed condition of valve air flue 14; When moving to lateral wall, piston 7 dodges while opening valve air flue 14, for opening the opening state of valve air flue 14.
As shown in Figure 3, at piston 7 during in backstroke, before the cylinder body air flue 16 of calming the anger enters the top (rodless cavity of piston rod 9) of piston 7, promotes piston 7 and moves downward, and the gas of piston 7 bottoms will drain into atmosphere by opening valve air flue 14; In the time that piston 7 moves to pass make and break valve air flue 14 gradually, distributing valve 13 recovers again limes superiors position.When piston 7 reaches by inertia after bottom dead centre (speed is 0), start again impact stroke.
From above-mentioned operating principle, only need to change the piston 7 in air hammer 6, as adopt the piston 7 of equal in quality, different structure, and change gas booking size by changing piston 7 structures, just can in same impactor agent structure, change impact property (impact energy, frequency of impact).Be illustrated in figure 4 piston 7 structures that one can make " backhaul is driven valve in advance "; Be illustrated in figure 5 piston 7 structures that one can make " stroke is driven valve in advance "; Be illustrated in figure 6 piston 7 structures that one can make " stroke open valve lag behind ", three kinds of modes be all by change S(open valve in advance and lagged displacement amount) can realize the numerous variations example of impactor performance.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
