Abstract
The invention relates to a clamping device for a drill stem of a hydraulic drilling rig and belongs to the field of engineering machinery. According to the technical scheme, the clamping device for the drill stem of the hydraulic drilling rig comprises two symmetric fan-shaped columnar chucks for clamping the drill stem, a threaded rod is arranged in the middle of the outer side face of each chuck, a rotating rod is arranged on the rear portion of each threaded rod, the front end of each threaded rod and the corresponding fan-shaped chuck are movably connected, the threaded rods can rotate, the middle of each threaded rod penetrates through a threaded hole formed in a drill bit frame of the hydraulic drilling rig, and the threaded holes are matched with the threaded rods. A fixed engagement opening of a clamp is changed into a movable engagement opening, one machine can achieve multiple functions, cost for purchasing different drilling rigs is greatly saved, and economic benefit is huge. After the drilling rig is modified, flexibility and practicability not borne by the original drilling rig are added, the value of equipment is increased, and social benefit is very good. Compared with existing adjustable clamps, the clamping device is simple in structure, capable of being improved on the basis of an existing clamp structure, low in manufacturing cost and high in maintainability.
Description
Technical field
The present invention relates to a kind of hydraulic drill rig drill rod grip device, belong to engineering machinery field.
Background technology
The existing hydraulic drill rig using of this department, is the fixing clip tooth device that can only fix Φ 75mm drilling rod, and in underground work
When it will usually use multiple various sizes of drilling rod such as Φ 50mm, Φ 42mm, Φ 38mm, fixing clip tooth device is to the peace of drilling rod
Dress is made troubles, and affects working performance.
The holder structure that existing scalable fastens drilling rod size is complicated, is unfavorable for the maintenance in down-hole.And due to
Precise structure, the life-span using in the presence of a harsh environment is low.
Content of the invention
The present invention provides a kind of hydraulic drill rig drill rod grip device, solves existing clamper and can not change multiple dynamic diameters
Drilling rod and the problem of ground high cost of complicated clamper life-span.
For achieving the above object, the technical solution used in the present invention is：
Hydraulic drill rig drill rod grip device, including the chuck of the two symmetrical fan-shaped columns accommodating drilling rod, in the lateral surface of chuck
Portion sets screw rod, and the rear portion of screw rod sets swing arm, between described screw front end and fan-shaped chuck for is flexibly connected and screw rod rotatably, spiral shell
The screw being arranged in hydraulic drill rig drill bit frame is run through at the middle part of bar, and screw is coordinated with screw rod.
Preferably, the drift angle of described chuck sets drilling rod clip slot, between the fan-shaped plan of chuck and clip slot, set rectangular channel.
Further preferred, clip slot extends to the inside of chuck and forms arcuate groove.
As preferably, the lateral surface of described chuck sets the spherical pore of indent, and the inside maximum gauge of spherical pore is more than outer
The bore dia of leakage, the end of described screw rod sets spheroid, and the spheroid of described screw front end is placed in spherical in the hole can be around pitch
Axis rotates.
The fixing articulation port of clip tooth device is changed to movable articulation port, it is possible to achieve " a tractor serves several purposes ", greatlys save purchase
The cost of different rigs, economic benefit is huge.Improved rig increased motility not available for original rig, practicality
Property it is achieved that equipment increment, social benefit is very good.
Compare existing adjustable gripper, present configuration is simple, can be transformed, make on existing holder structure
Valency low cost is maintainable high.

Specific embodiment
The present invention as illustrated, hydraulic drill rig drill rod grip device, including the two symmetrical fan-shaped columns accommodating drilling rod
Chuck 1, sets screw rod 2 in the middle part of the lateral surface of chuck 1, the rear portion of screw rod 2 sets swing arm 3, is to live between described screw rod 2 front end and chuck 1
It is dynamically connected and screw rod 2 is rotatable, the screw 5 being arranged in hydraulic drill rig drill bit frame, screw 5 and spiral shell are run through in the middle part of screw rod 2
Bar 2 coordinates.
The drift angle of chuck 1 sets drilling rod clip slot 6, and drilling rod is arranged in the clip slot 6 of two symmetrical chucks, the plane of chuck 1 and folder
Rectangular channel 7 is set between groove 6.Clip slot 6 extends to the inside of chuck and forms arcuate groove 8.
The lateral surface of chuck 1 sets the spherical pore 9 of indent, and the inside maximum gauge of spherical pore 9 is more than the bore dia of leakage, institute
The end stating screw rod 2 sets spheroid 10, and the spheroid 10 of described screw rod 2 front end is placed in spherical pore 9 and can turn around pitch axis
Dynamic.
Rotate swing arm, drive screw rod rotation, because the spheroid of screw front end is arranged on the spherical in the hole of chuck, screw rod can carry
Dynamic chuck outwardly or inwardly moves on center line of bolt hole.
During chuck inward, the distance between chuck reduces, and the clip slot between two chucks diminishes, and can clamp small diameter
Drilling rod.Chuck moves out, and distance between chuck increases, and clip slot becomes large-sized, being capable of the drilling rod that clamps of Panasonic installing
New drilling rod.
This device can be transformed on the chuck of fixed dimension, easy to maintenance, and cost is low.
