Description
Technical field
What the utility model discloses a kind of rotary drilling rig goes into the rock exciting device, belongs to engineering mechanical components.
Background technology
At present, it is the world-famous puzzle of generally acknowledging that rotary drilling rig is gone into the rock construction, existing rotary drilling rig; Do not have exciting device between drilling rod and the drill bit, directly be connected between drilling rod and the drill bit, when carrying out bore operation with bearing pin; Formation hardness and intensity are bigger, and drill bit often is stuck, and hydraulic system pressure sharply increases; Engine overload is flame-out, causes efficiency of construction low, has a strong impact on construction speed.
The utility model content
The utility model is intended to provide a kind of can improve rock efficient, and that reduces rotary drilling rig that drill bit damages goes into the rock exciting device.
The purpose of the utility model can reach through following measure: a kind of rotary drilling rig go into the rock exciting device; Comprise control system, fluid power system, vibration-proof structure and vibrator; Wherein, The control system comprises sensor, controller and electric-controlled hydraulic distributing valve; Fluid power system comprises hydraulic gyration body, hydralic hose, elevator cylinder and hydraulic motor, and vibration-proof structure comprises link, vibration isolation rubber piece and following link, and vibrator comprises casing, first eccentric wheel, second eccentric wheel; Said hydraulic gyration body is installed on the unit head lower end of rotary drilling rig, and said vibration-proof structure is positioned at the drilling rod below of rotary drilling rig; Said vibrator is positioned at link lower end down, and vibrator is connected with the hydraulic motor output.
The technique scheme difference with the prior art is: vibration signal can be collected by the control system, controls vibrator through fluid power system after the treated analysis; Vibrator can produce high-frequency vibration, and drill bit produces violent bump and fragmentation to rock under this vibration, and drill bit continues to pierce rock, simultaneously big catalase is become small crushed stone; The moment of torsion of vibration-proof structure ability transferring power head, and in the vibration that reduces unit head.
Further, in order to guarantee the unimpeded of hydraulic motor oil-feed loop, hydraulic motor is installed on down in the link, and its input is connected with hydralic hose.
Further, cause that the vibration-proof structure parts are loose in order to prevent because vibration is excessive, said link, vibration isolation rubber piece and the following link gone up is connected fixing with the bolt and nut coupling assembling.
The disclosed rotary drilling rig of the utility model go into the rock exciting device, reasonable integral structure is made easily, can effectively reduce the bit freezing phenomenon, improves the efficient of boring rock work; Can guarantee that engine running is steady, improve motor application life; Reduce impact load, prolonged the application life of key components such as drilling rod, drill bit.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of going into rock exciting device embodiment of the utility model rotary drilling rig.
The specific embodiment
As shown in Figure 1: a kind of rotary drilling rig go into the rock exciting device, comprise control system, fluid power system, vibration-proof structure and vibrator.
Wherein, the control system comprises sensor, controller and electric-controlled hydraulic distributing valve, and sensor connects controller, and controller connects the electric-controlled hydraulic distributing valve, and the electric-controlled hydraulic distributing valve connects the hydraulic pump on the rotary drilling rig.
Fluid power system comprises hydraulic gyration body 2, hydralic hose 5, elevator cylinder 3 and hydraulic motor 10.Hydraulic gyration body 2 is installed on unit head 1 lower end of rotary drilling rig; The bottom dress elevator cylinder 3 and the rotation motor 4 of hydraulic gyration body 2; Rotation motor 4 can drive 3 rotations of elevator cylinder, and owing on the elevator cylinder 3 hydralic hose 5 is housed, hydralic hose 5 is connected with hydraulic motor 10 inputs; Hydraulic oil then can reach the input of hydraulic motor 10 along hydralic hose 5, for hydraulic motor 10 provides power.
Vibration-proof structure comprises link 7, vibration isolation rubber piece and following link 8, and this vibration-proof structure is installed between drilling rod 6 and vibrator 9; Wherein, last link 7 and drilling rod 6 are connected through bearing pin, and following link 8 connects vibrators 9, and the vibration isolation rubber piece is between last link 7 and following link 8, and last link 7, vibration isolation rubber piece are connected with following link 8 usefulness bolt and nut coupling assemblings to be fixed.Vibration-proof structure can transferring power 1 moment of torsion with reduce the vibration of vibrator to unit head 1.
During rotary drilling rig work, the sensor of control system can be responded to the vibrational feedback of drill bit 11 rock drillings, and feedback signal is imported controller; Controller is analyzed the vibration state of rock, finds out the intrinsic frequency of fractured rock, to hydraulic distributing valve output control signal corresponding; Thereby regulate the flow that transfers to hydraulic motor 10; The vibration frequency of control vibrator 9, vibrator 9 produces high-frequency vibration, and drill bit produces violent bump and fragmentation to rock under this vibration; Drill bit continues to pierce rock, simultaneously big catalase is become small crushed stone.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
