Description
Technical field
The utility model belongs to mining industry drilling equipment field, more particularly to a kind of rock drill clamper.
Background technology
Clamper is a part for all-hydraulic power head churn, the purpose is to drilling tool in holding holes, prevents drilling tool from sliding,
Clamper can complete the action of dismounting drilling rod with power head cooperating.Existing clamper is divided into normally closed type clamper, normally opened
Several classes such as formula clamper, combined type clamper., should but rock drill needs manually to add drilling rod in drilling process, pushes away drilling rod
Not only labor intensity is big for process, easily occurs squeezing hand in work progress, but also loses time to grow, and does not allow when adding drilling rod easily-controllable
The concentric of two drilling rods is made, the situation of sideslip occurs.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of rock drill clamping
Device, reduces and adds drilling rod in rock drill drilling process, moves back the labor intensity of drilling rod.
Technical solution：To achieve the above object, the technical solution of the utility model is as follows：
A kind of rock drill clamper, including circular clamp ring, bottom bracket, hydraulic intensifier and hand oil pump, the bottom
Bracket is reverse V-shaped structure, and the bottom bracket is fixed on borer frame, and the bottom bracket upper end is provided with circular clamp
Ring, the circular clamp ring bottom offer through hole, and the hydraulic intensifier is arranged on the lower section of circular clamp ring, the hydraulic pressure
The piston rod of booster is threaded through in the through hole, and the extending direction of the piston rod is directed toward the center of circular clamp ring, institute
State hand oil pump to be arranged on borer frame, and the hand oil pump is connected with hydraulic intensifier by hydraulic oil pipe.
Further, the piston rod is set with via clearance, and the top of the piston rod is arc structure.
Further, it is provided with slips in the circular clamp ring.
Further, the hand oil pump is low pressure fuel pump, and the rated pressure of the hand oil pump is 5MPa.
Beneficial effect：The work for adding drilling rod, moving back drilling rod that the utility model can be reduced in rock drill drilling process is strong
Degree and danger coefficient, improve the speed for changing drilling rod, and 10% can be about improved through front and rear contrast drilling efficiency；And clamping drilling rod
When, it is ensured that drilling rod is concentric with drilling machine, reduces error.
Brief description of the drawings
Attached drawing 1 is the scheme of installation of the utility model；
Attached drawing 2 is the overall structure diagram of the utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, a kind of rock drill clamper, including circular clamp ring 5, bottom bracket 6, hydraulic pressure increase
Depressor 7 and hand oil pump 8, the bottom bracket 6 is reverse V-shaped structure, before the bottom bracket 6 is fixed on borer frame 1
End, 6 upper end of bottom bracket are provided with circular clamp ring 5, the central axis of circular clamp ring and the central axis weight of drilling machine 4
Close, 5 bottom of circular clamp ring offers through hole 9, and the hydraulic intensifier 7 is arranged on the lower section of circular clamp ring 5, described
The piston rod 10 of hydraulic intensifier 7 is threaded through in the through hole 9, and the extending direction of the piston rod 10 is directed toward circular clamp ring
5 center, the hand oil pump 8 is arranged on borer frame, and the hand oil pump 8 is connected setting with hydraulic intensifier 7.Institute
State 7 bottom of hydraulic intensifier to be provided with into and out of oilhole, the hand oil pump is connected with hydraulic intensifier by hydraulic oil pipe, rock
After stone completes a drilling rod operation, manually pressure oil pump 8 provides pressure as power source for hydraulic intensifier 7, and drilling rod 2 passes through
Hydraulic intensifier is fixed in circular clamp ring 5, the collective effect of piston rod 10 and circular clamp ring 5, it is ensured that when adding brill
Drilling rod center keeps conllinear with the drilling rod that has fulfiled assignment, the Clamping Center of drilling machine, beneficial to the operation added when boring or move back brill, subtracts
Less since assembly connection caused by decentraction is difficult；And the drilling rod of different-diameter is could be applicable to, drilling rod 2 is clamped firm
Afterwards, drilling machine Switching Power Supply is switched to inverting, crawl rock drill, can depart from drilling rod and rock drill, afterwards by rotary rock drill
Machine is run to initial segment along drilling machine slideway 3, manually by drilling rod precession into clamped drilling rod, then by rock drill to drilling side
To operation, drilling machine can be automatically performed drilling rod connection work in the process of running, and during drilling rod is added, move back drilling rod, no
Personnel are needed to help drilling rod always, when two drilling rods are connected, labor intensity and danger coefficient all largely reduce, and carry
The speed for changing drilling rod is risen, in whole work process, through front and rear contrast, drilling efficiency can about improve 10%.
The piston rod 10 and 9 gap setting of through hole, the top of the piston rod 10 is concave arc shape structure.The concave arc shape
The radius of curvature of structure is less than or equal to the radius of curvature of circular clamp ring 5 so that more stable when clamping drilling rod.
Slips 11 is provided with the circular clamp ring 5.Increase the frictional force of 5 inner ring of circular clamp ring, prevent drilling rod from sliding
Dynamic or rotation, but also the direct abrasion to circular clamp ring 5 can be avoided.
The hand oil pump 8 is low pressure fuel pump, and the rated pressure of the hand oil pump 8 is 5MPa.Low pressure fuel pump makes
Used time is safer.And hydraulic intensifier can carry out pressure amplification to low pressure fuel pump, to provide enough chucking powers, and low pressure
Oil pump can also reduce the cost of equipment, simplify equipment.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
