Abstract
The utility model relates to an independent rotary rock drill, which is composed of a drill rod, a head section, a gas distribution impactor, a handle, a control valve and a motor retarding mechanism, wherein, the gas distribution impactor is a rod valveless match impactor, and the head section, the gas distribution impactor and the motor retarding mechanism are connected together via flanges by connecting screw rods. The utility model has the advantages of independent impact and turning and high drilling speed and efficiency, and the utility model can avoid poker bar clamping accidents.
Description
The utility model belongs to rock drilling machinery.
Mostly existing hammer drill is the internal rotary type hammer drill, its structure mainly is that origin compound lever and ratchet, ratchet are formed impact and rotary system, this kind hammer drill in use impacts and turns round and can not separate, when change at borehole drilling under pricker or joint, the rock stratum complicated situation midway, folder pricker accident often takes place, in addition because the flywheel moment and the end thrust of interior rotary rock drill is non-adjustable, and its cutting rate when increasing, drilling depth is sharply descended.
The purpose of this utility model is to provide a kind of can make the impact of hammer drill and revolution separate, thereby improves the Independent Rotary Rock Drill of cutting rate and efficient
The utility model is made up of parts such as drill steel, head, connection screw rod, silencer cover, bar portion valveless distribution impactor, motor reducer structure and control valve handles.
Be described in detail content of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of bar of the present utility model portion valveless distribution impactor;
Fig. 3 is the transmission scheme schematic diagram of the utility model motor reducer structure.
Among the figure: 1 drill steel, 2 heads, 3 connect screw rod, 4 silencer covers, 5 bar portions valveless distribution impactor, 6 motor reducer structures, 7 control valve handles, 8 cylinder bodies, 9 piston rods, 10 stroke air flues.
Structure of the present utility model as shown in Figure 1, the front end of head has interior six side's running-ons, be used for installing and blocking drill steel, head, bar portion valveless distribution impactor and motor reducer structure link together, and handle is connected in the rear portion of motor reducer structure, and 2 control valves are housed on the handle, one is used for control lever portion valveless distribution impactor, and another is used for controlling the motor reducer structure.Bar of the present utility model portion valveless distribution impactor as shown in Figure 2, form by cylinder body 8 and piston rod 9, on cylinder body 8, have stroke air flue 10, its operating principle is because the valveless distribution of bar portion has only about 1/3 of stroke to carry out distribution, all the other then the expansion work of pressured gas piston is quickened, this just needs suitably to strengthen the initial volume of calming the anger before expanding to reach certain ballistic work in order to make it have suitable coefficient of fullness, and during the valveless distribution of bar portion, two bigger stroke air flues 10 of basal area itself just have the effect of back air cushion concurrently, back air cushion size is shortened dramatically, and can make full use of distribution area that afterbody occupies, when same piston diameter, can increase the area of calming the anger and improve ballistic work.Motor reducer structure transmission scheme of the present utility model as shown in Figure 3; First order planetary reduction gear part in the 2K-H transmission, i.e. fixed gear ring b, planetary gear f, pivoted arm h (being part in the line frame among the figure), planetary gear f is a driving wheel, will structurally combine as the motor and the reducing gear of power output like this.Promptly be equivalent to arrange one deck gear again on the width basis of ordinary gear motor, can obtaining big reduction of speed ratio with direct driving drill steel.
Impact that this reality is novel and revolution are separately independently, therefore, the size of impact force and flywheel moment can be divided other levelling according to rock drilling hardness and structure different, hammer drill is worked under the condition of impact force, flywheel moment and the end thrust of optimum, thereby improve the cutting rate and the efficient of machine.And can avoid pressing from both sides the pricker accident.Embodiment, YTZ30 type supporting leg type independently turns round the air rock drill structure as shown in the figure.Design parameters: machine is heavy:＜30 kilograms of total length: 640mm use air pressure: 5～7Kg/cm
2Cylinder bore: 76mm piston structure stroke: 55mm frequency of impact: 2200 times/minute ballistic works:＞10 kilogram-metre drill steel rotating speeds: 0～200 rev/min of air consumption:＜4.2 meters
3/ minute moment of torsion:＞500Kgcm uses hydraulic pressure: 2～3 kilograms/cm
2Airline hose internal diameter: 25mm water delivery hose internal diameter: 13mm bore diameter: 28～40mm maximum drilling depth: 5m bit shank size: six side's opposite side size: 22mm * 108mm.
Claims (3)
1, a kind of drill steel, head, distribution impactor, handle and control valve of including is at interior Independent Rotary Rock Drill, it is characterized in that this hammer drill also is equipped with the motor reducer structure, its impactor is a bar portion valveless distribution impactor, head, distribution impactor and motor reducer structure is linked together by flange by connecting screw rod.
2, Independent Rotary Rock Drill as claimed in claim 1 is characterized in that said bar portion valveless distribution impactor is made up of cylinder body and piston rod, has the stroke air flue on cylinder body.
