Abstract
The utility model discloses an impacting and rotating bolting machine which comprises a compressed air intake pipeline, a cylinder and a pneumatic motor. The compressed air intake pipeline is connected to a motor control valve. The motor control valve is provided with two control valves. One control valve is connected to the cylinder, and the other control valve is connected to the pneumatic motor. The compressed air intake pipeline is connected with an airleg control valve which is connected to an airleg. The cylinder and the pneumatic motor are respectively connected with a drill rod spindle. The cylinder drives a drill rod to repeat impacting. The pneumatic motor drives the drill rod to rotate. The impacting and rotating bolting machine has the functions of a pneumatic rotating roofbolter and the functions of a pneumatic rock drill, is available for independent rotating and independent impacting and also available for simultaneous rotating and impacting, and has the advantages of small size, light weight, convenience in operation and maintenance and adjustable performance.
Description
Technical field
The utility model relates to pneumatic machinery, specifically be a kind of possess impact and rotate the roof-bolter of two kinds of functions.
Background technology
The coal mine roadway roof timbering adopts roof-bolter to finish at present, and roof-bolter only has spinfunction.Use roof-bolter to finish roof timbering operation existence under the tight roof condition and use duration, air consumption is big, the uneasy congruent hidden danger of operating personnel.Yet, in hard rock, use percussion hammer, the drilling construction time decreased, but changing on the links such as extension arm, powder stick stirring and must realize by utilization rotation roof-bolter.Often exist the phenomenon that the hard rock interlayer is arranged in the soft rock in the on-the-spot country rock, particularly when beating the anchor cable hole, present rig can't be constructed.Therefore, study a kind of novel anchor rod machine, realize impacting double spinfunction and have great importance.
Summary of the invention
The purpose of this utility model provides a kind of impact, rotating integrated formula roof-bolter, and this roof-bolter can rotate separately and impact, and can open simultaneously again.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of impact, rotating integrated formula roof-bolter, comprise compressed air inlet pipe road, the gentle motor of cylinder, the air inlet pipeline is connected to motor control valve, and motor control valve is provided with two by-pass valve controls, a by-pass valve control connects cylinder, and another by-pass valve control connects the gas motor.
Cylinder is connected with the drilling rod main shaft respectively with the gas motor, and cylinder drives drilling rod and back and forth impacts, and the gas motor drives the drilling rod rotation.Motor control valve has multidirectional control function, realizes the enforcement of roof-bolter rotation, percussion action.Under normal top board condition, this roof-bolter can punch by rotation mode, to give full play to the characteristics of rotary high-efficient.When running into hard rock, start cylinder ram and break up rock.Increase to need change (lengthenings) drilling rod or bolthole and set and finish when carrying out anchoring along with drilling depth, the roof-bolter rotation realizes that drilling rod lengthens the anchoring cartridge stirring, finishes anchor rod anchored operation.When running into the top board of different lithology, can constantly switch as the case may be, avoided two kinds of device contexts frequently to move, system frequent switch in geomantic omen reduces anchor pole and sets each link time, guarantees the back immediate support, thereby guarantees operating personnel's safety.
The rotating integrated formula roof-bolter of impact described in the utility model has possessed two kinds of functions of pneumatic rotation jumbolter and air drill, both can rotate separately and impact, but both open simultaneously again, also have the characteristics that volume is little, in light weight, easy to operate, easy to maintenance, performance is adjustable.

Among the figure, 1-compressed air inlet pipe road, 2-cylinder, 3-gas motor, 4-motor control valve, 5-air leg control valve, the 6-air leg, 7-inlet pipeline, 8-water sieve, the 9-water control valve, 10-strainer, 11-oil sprayer, the 12-compressed air joint, 13-compressed air screen pack, 14-noise damper, the 15-rapid escape valve, the 16-water swivel.
The specific embodiment
Below in conjunction with accompanying drawing the claimed technical scheme of the utility model is done and to be specified.
A kind of impact, rotating integrated formula roof-bolter, comprise compressed air inlet pipe road 1, cylinder 2 gentle motors 3, air inlet pipeline 1 is connected to motor control valve 4, and motor control valve 4 is provided with two by-pass valve controls, a by-pass valve control connects cylinder 2, and another by-pass valve control connects gas motor 3.
To motor control valve 4, motor control valve 4 bifurcations are controlled gas motor 3, another control cylinder 2 for one to compressed air through strainer 10, oil sprayer 11, compressed air joint 12, compressed air screen pack 13 backs.
Gas motor 3 jointed rod main shafts, a by-pass valve control of unlatching motor control valve 4 is equipped with noise damper 14 on the gas motor 3.Gear rotation in the compressed air-driven gas motor 3, output gear drive the rotation of main shaft clockwise direction after slowing down to reductor.
Establish piston in the cylinder 2, piston nose jointed rod main shaft, another by-pass valve control of unlatching motor control valve 4, compression cylinder 2 drives main shaft and back and forth impacts.
Compressed air inlet pipe road 1 connects air leg control valve 5, and the air leg control valve is made up of last air leg control valve and following air leg control valve, and air leg control valve 5 connects air leg 6.Air leg 6 withstands shocks, rotates two kinds of active forces.
Compressed air also will filter before entering air leg control valve 5, is provided with rapid escape valve 15. and pulls unlatching air leg control valve 5 between air leg control valve 5 and air leg 6, and compressed air enters air leg 6 epicoeles through rapid escape valve 15, air leg 6 elongations; Close air leg control valve 5, air leg 6 epicoele residual air are from rapid escape valve 15 emptying, and air leg 6 falls after rise.
Also can putting the water rinse-system, described water rinse-system comprises inlet pipeline 7 and is connected water sieve 8 and water control valve 9 on the inlet pipeline 7 on roof-bolter described in the utility model.Roof-bolter is provided with and makes water jacket, and the drilling rod main shaft is provided with endoporus, opens water control valve 9, and flushing water enters drilling rod, wash boring through water swivel 16, screen pack 8, water control valve 9, water jacket, main shaft endoporus.
The open amount of each valve of manual adjustments can be regulated rotating speed, thrust or the water yield.Best service condition should be set to:
A, operating air pressure should keep 0.4-0.63MPa, and it is clean and dry that compressed air is wanted.
B, hydraulic pressure should keep 0.6-1.2MPa, and it is clean that water quality is wanted, otherwise the water route is blocked easily.
C, drilling rod require to have certain elasticity and abrasion resistance, ban use of crooked drill pipe.
