In view of this, the purpose of this utility model provides a kind of hydraulic pressure rock drilling rig, can make rotating disk realize multistage stably rotating speed, can make the master again, pay winding drum by a cover transmission system drives and control respectively.

The purpose of this utility model is achieved in that it comprises that mainly a kind of hydraulic pressure rock drilling rig comprises engine, transmission device, main oil pump, gravel pump, the drainage pump, slush pump, the elevator unit, drilling cramp, fire hose platform, kelly, rotating disk, drilling rod in the hole, drill bit, crawler body and platform, it is characterized in that: rotating disk mainly is by oil motor, reduction box, rotary case, pinion, pivoting support and turntable are formed, wherein pivoting support is fixed on the turntable below, and fluidly be bearing on the rotary case, oil motor connects pinion through reduction box, and with pinion and the engagement of pivoting support inner edge gear ring; The elevator unit mainly be with two jaw clutches that connect on the main shaft connect respectively pivot be enclosed within on the main shaft the master winch tube with pay winding drum and main shaft and be connected oil motor through reduction box.

Owing to adopt such scheme: rotating disk and master, pair winding drum turn round steadily, and compact conformation can also reach the rotating disk high pulling torque and multistage rotating speed rationally mates.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, the utility model exemplary embodiments outside drawing;

Fig. 2, the utility model exemplary embodiments rotating disk transmission schematic diagram;

Fig. 3, the utility model exemplary embodiments hoist engine transmission schematic diagram.

Among the figure:

1, engine 2, transmission device 3, main oil pump 4, gravel pump 5, drainage pump

6, slush pump 7, elevator unit 8, drilling cramp 9, water tap 10, kelly

11, drilling rod 13, drill bit 14, crawler body 15, platform in rotating disk 12, the hole

111, oil motor 112, reduction box 113, rotary case 114, pinion 115, pivoting support

116, turntable 117, bushing 71, oil motor 72, reduction box 73, main shaft

74, check mechanism 75, pair winding drum 76, master winch tube 77, jaw clutch 78, bearing support

Rotating disk 11 is made up of oil motor 111, reduction box 112, rotary case 113, pinion 114, pivoting support 115, turntable 116 and bushing 117, wherein the axle of oil motor 111 connects the power shaft of reduction box 112, and the output shaft of reduction box 112 connects a pinion (spur gear) 114, this pinion 114 is meshed with the inner edge gear ring of pivoting support 115, and pivoting support 115 is fixedlyed connected with turntable 116 and rollably is bearing on the rotary case 113; Bushing 117 engages by the square face with turntable 116 and combines (clamping) with kelly 10 again, make the drill bit 13 of kelly 10 lower ends can obtain different rotation (conversion oil motor 111 rotating speeds own or the speed reducing ratio of regulating reduction box 112), make big, the stability of rotation of rotating disk 11 carryings, as shown in Figure 2.

Elevator unit 7 is made up of oil motor 71, reduction box 72, main shaft 73, check mechanism 74, pair winding drum 75, master winch tube 76, jaw clutch 77 and bearing support 78.Wherein, main, pay winding drum 76,75 are articulated on the main shaft 73 simultaneously, and two jaw clutches 77 are separately positioned on the master, pay winding drum 76, on 75 two outside main shafts 73, so that control is main respectively, pay winding drum 76, the connection of 75 main shafts 73, main simultaneously, pay winding drum 76, the other check mechanism 74 that is respectively equipped with of 75 outer rims, the gear of oil motor 71 in reduction box 72, drive main shaft 73, drive master winch tube 76 through jaw clutch 77 again, or pair winding drum 75, or drive main simultaneously, pay winding drum 76,75, compact conformation, also be convenient to centralized operation, running simultaneously is also steady, as shown in Figure 3.

The operating principle of present embodiment, as shown in Figure 1,

Engine 1 drives main oil pump 3 through transmission device 2 and produces pressure oil, drives rotating disk 11 interior two low-speed big oil motors, 111 revolutions through oil pipe and control valve thereof, makes kelly 10 rotations, drill bit 13 broken ground; Drill bit 13 hangs through water tap 9 water supply, drilling cramp 8, supplies with feedings by master winch tube 76, and the increase and decrease of drilling rod 12 drives by paying winding drum 75 in kelly 10, the hole;

Drill bit 13 broken ground are with after circulation fluid mud mixes, and constantly the circulation fluid of feeding returns the mud-settling pit to ground; Its flow process is: slush pump 6 is extracted the mud liquid of proportion about 1.03～1.3 out, let out at the bottom of the hole and mix the back with boring mud and upwards return to the ground water channel by drilling rod 12, drill bit 13 in gravel pump 4, water tap 9, kelly 10, the hole along the space of 12 outsides of drilling rod in the hole and well (hole) wall, precipitate and flow into pond, mud shallow lake, boring mud and mud separation, mud liquid flows back to mud pit and recycles;

The boring mud that drill bit 13 revolution gets out is with after mud liquid mixes, under the pull of vacuum and the effect of well head water level atmospheric pressure of gravel pump 4, boring mud and mud liquid is drilling rod 12, kelly 10, water tap 9 and gravel pump 4 sucking-offs in drill bit 13, hole, drain into mud-settling pit, slurry is with after slag separates, mud liquid flows back in the well through mud pit and circulation waterway, forms vacuum for the ease of gravel pump 4 startings, and this rig is set up a drainage pump 5 and an one way valve.
