Take a broad view of present known rotary drilling rig, do not have exciting device between drilling rod and the drilling tool, directly be connected between drilling rod and the drilling tool with bearing pin.When having a large amount of rocky grounds to make bore operation, drilling tool contacts with large rock mass, can't be in the time of most of with catalase, and this moment, drilling tool and drilling rod stopped the rotation, and caused the bit freezing phenomenon; At this moment, engine power arrives peaking rapidly, and hydraulic system pressure arrives peaking rapidly.This type of phenomenon repeatedly taking place can cause following consequence: 1, reduces efficiency of construction; 2, reduce motor application life; 3, hydraulic oil temperature height, pressure are big, and the hydraulic system element descends application life; 4, pivoting support and pinion probability of damage increase; 5, energy consumption increases; 6, drilling rod and drilling tool frequently bear heavily loaded fluctuating load and easily produce the fatigue fracture phenomenon.
Summary of the invention
The objective of the invention is for fear of or reduce bit freezing phenomenon when boring the rock operation, and provide a kind of rock-entering vibrating device for rotary drilling machine.This device is connected between drilling rod and the drilling tool, and it can produce high-frequency vibration; Under this vibration, drilling tool produces violent bump and fragmentation to rock, and drilling tool continues rotation and pierces rock, simultaneously big catalase is become small crushed stone.This moment, motor operated steadily, and hydraulic system pressure is constant, had avoided a lot of bad phenomenon to produce.
The present invention implements with following technical scheme: a kind of rotary drilling rig go into the rock exciting device, be installed between drilling rod and the drilling tool, it comprises unit head, unit head is installed in rotary drilling rig and bores on the mast, can move up and down, it is characterized in that: also comprise the hydraulic gyration body that is installed in below the unit head, damping device and be connected vibrator below the damping device; Damping device is by last link, following link and be positioned between the two yielding rubber piece and be connected and fixed and form; The moment of torsion of vibration isolation rubber piece energy transferring power head can also reduce the vibration to unit head; The elevator cylinder of hydralic hose I is housed below the hydraulic gyration body, and the elevator cylinder is driven by hydraulic motor I; Unit head drives the drilling rod rotation, and drilling rod is connected by bearing pin with last link; Hydraulic motor II is equipped with in following link bottom; Hydraulic oil is provided by hydralic hose II among the hydraulic motor II, and hydralic hose II is connected with hydralic hose I; Hydraulic motor II drives the vibrator that is contained in down the link bottom, and following link is connected with vibrator; Drilling tool is housed below the vibrator; The two is connected by bolt and nut coupling assembling III.Described unit head inside has the multipath hydraulic pipeline to arrive the hydraulic gyration body.
Described elevator cylinder and drilling rod rotate synchronously.
When described drilling rod and inside moved up and down, hydraulic motor I drove the rotation of elevator cylinder, and hydralic hose I can adjust length.
The inside multipath hydraulic pipeline of described hydraulic gyration body by the middle part of elevator cylinder, arrives the outside of elevator cylinder, and I links to each other with hydralic hose.
Owing to adopted technique scheme, the present invention to improve the functional performance of rotary drilling rig complete machine, advantage is as follows: (1) reasonable integral structure, make easily, volume is little, in light weight; (2) the bit freezing phenomenon significantly reduces, and has improved the efficient of boring rock work; (3) engine running is steady, has improved motor application life; (4) hydraulic system pressure is steady, avoids hydraulic oil temperature too high, further improves hydraulic system element application life; (5) heavy shock loads reduces, and has prolonged the application life of key components such as drilling rod, drilling tool, pivoting support and pinion; (6) unnecessary energy consumption, energy-conserving and environment-protective have been reduced.
