Description
Technical field
The invention belongs to oil drilling and extracting equipment technical field, more particularly, to novel clamp holder.
Background technology
When drilling tool lifting manipulator is oil drilling or workover treatment, the instrument of lifting drilling tool is usually used.In existing skill
In art, lifting manipulator clamping different diameter specifications drilling tool need replacing corresponding centering machine, in drilling process, it is necessary to
The operation such as make up a joint, pull out of hole, it is necessary to rotary tools in these operating process, and existing machinery general only pincers tooth on hand
Clamper, after clamping tooth clamp holder clamping drilling tool, it is impossible to follow drilling tool to rotate together, limit the rotation of drilling tool.But unclamp pincers tooth
Clamper may fall, topple over, can threaten staff in the case where drilling tool is not connected also or threaded off completely
Life security.Therefore clamping can be played to drilling tool, righting is made after the pincers tooth clamper of release mechanism hand there is an urgent need for a kind of
Clamper.
The content of the invention
The object of the present invention is to provide a kind of simple in structure, easy to operate, applicable different size drilling tool, clean face oil righting to make
With the high drilling tool roller clamper of, production efficiency.
The technical scheme is that：Novel clamp holder, including two clamping calipers, described two middle parts for clamping caliper
Articulated connection, described two upper ends for clamping caliper are respectively equipped with a support plate, and the main folder that is articulated and connected in the support plate is tight
Roller and secondary pinching roller, adjusting rod is connected on the secondary pinching roller, and the adjusting rod is set on the supporting plate, the adjusting
The end of bar is equipped with latch segment, and clamping cylinder, the side of the clamping cylinder are equipped between described two lower ends for clamping caliper
For piston end, adjustment cushion block is connected between the piston end and clamping caliper, the opposite side of the clamping cylinder is cylinder body end,
Buffer stopper is equipped between the cylinder body end and clamping caliper, is clamped between described two main pinching rollers and two pinching rollers
There is drilling tool.
Further, the clamping cylinder is bolted on two and clamps on caliper.
The present invention has the advantages and positive effects of：Due to the adoption of the above technical scheme, four primary and secondary pinching rollers it
Between be clamped with drilling tool, certain clamping and centralizing function are played to drilling tool, passes through two clamping clips of extension and contraction control of clamping cylinder
The closure degree of body, secondary pinching roller can adjust the degree of its clamping by adjusting rod, and determining can profit after the degree of clamping
With latch segment latched position, avoid the problem that drilling tool falls, rotated without limitation on drilling tool, the clamping for simultaneously clamping on roller is bored
The mode of tool, can expand the drilling tool specification for needing to clamp, more convenient to use；It is easy to maintenance with simple in structure, add
The advantages that work cost is low, production efficiency is high.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：
1st, caliper 2, support plate 3, main pinching roller are clamped
4th, secondary pinching roller 5, adjusting rod 6, latch segment
7th, clamping cylinder 8, piston end 9, adjustment cushion block
10th, cylinder body end 11, buffer stopper 12, drilling tool
Embodiment
Elaborate below in conjunction with the accompanying drawings to the present invention.
As shown in Figure 1, novel clamp holder of the present invention, including two clamping calipers 1, described two middle parts for clamping caliper 1
Articulated connection, described two upper ends for clamping caliper 1 are respectively equipped with a support plate 2, and be articulated and connected main folder in the support plate 2
Tight roller 3 and secondary pinching roller 4, connect adjusting rod 5 on the secondary pinching roller 4, and the adjusting rod 5 is arranged in support plate 2,
The end of the adjusting rod 5 is equipped with latch segment 6, and clamping cylinder 7, the folder are equipped between described two lower ends for clamping caliper 1
The side of locking oil cylinder 7 is piston end 8, and adjustment cushion block 9, the clamping cylinder are connected between the piston end 8 and clamping caliper 1
7 opposite side is cylinder body end 10, is equipped with buffer stopper 11 between the cylinder body end 10 and clamping caliper 1, described two main folders are tightly rolled
Drilling tool 12 is clamped between wheel 3 and two pinching rollers 4.
The clamping cylinder 7 is bolted on two and clamps on caliper 1.
The course of work of this example：Drilling tool 12 is clamped between two main pinching rollers 3 and two pinching rollers 4, it is right
Drilling tool 12 plays clamping and centralizing function, by the closure degree of two clamping calipers 1 of extension and contraction control of clamping cylinder 7, clamps
The piston end 8 of oil cylinder 7 sets adjustment stick 9, its cylinder body end 10 is equipped with buffer stopper 11 to adjust clamping cylinder 7 with clamping caliper
Clamping degree between 1, avoids excessive clamped closed from damaging and clamps caliper 1, secondary pinching roller 4 can be adjusted by adjusting rod 5
The degree of its clamping is saved, is determined after the degree of clamping using 6 latched position of latch segment, avoids what falling occurred in drilling tool from asking
Topic；It is more convenient to use, while also have the function that to drilling tool righting, help.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be construed as limiting the practical range of the present invention.All all the changes and improvements made according to the present patent application scope
Deng, should all still belong to the present invention patent covering scope within.
