Description
Technical field
The utility model relates to a kind of fixture, particularly relates to a kind of rat hole drilling tool clamping device.
Background technology
In oil drilling, the degree of depth of oil well between 1000 ~ 8000 meters, but due to limited conditions, usually can only adopt and connect the length that the single mode of drilling tool increases drilling rod step by step, meet the requirements of drilling depth.Along with the increase of oil well depth, the single quantity of drilling tool also will increase.When workpeople makes up a joint, roughly have three kinds of modes, the first is manually fixed by the single drilling tool be placed in rat hole, rotated and tighten screw thread, complete and make up a joint, this mode, drop into manually more, very easily cause danger by the drilling rod on well head.The second is only rotated by the drilling rod on well head to tighten screw thread, and this mode easily drives the single drilling tool in rat hole when connecting, cause screwed connection not in place.The third is the single drilling tool that employing mechanical clamp fixes in rat hole, the object that though this mode reaches minimizing human input, screwed connection puts in place, but the clamping device mechanism of present stage is complicated, inconvenient maintenance, some chucking device is welded direct on rat hole mouth, integral demounting difficulty; Also some chucking device clamping bore is limited, and what be unfavorable for that oil well drills carries out smoothly.
In sum, be badly in need of in field of oil drilling the drilling tool clamping device that a kind of structure is simple, for convenience detach, dependable performance, versatility are good.
Summary of the invention
The technical problems to be solved in the utility model how to overcome the deficiencies in the prior art, provides the drilling tool chucking device that a kind of structure is simple, for convenience detach, versatility is good.
The utility model realizes the technical approach that above-mentioned purpose adopts: a kind of rat hole drilling tool clamping device, comprise sleeve, binding clip, hydraulic means, described sleeve upper end is provided with anchor ring, described sleeve lower end is provided with flange, described flange external diameter is greater than described anchor ring external diameter, described binding clip is arranged on described anchor ring upper end by cylindricality hinge, described cylindricality hinge inner is provided with main spring, described hydraulic means is fixed on described sleeve side by floor, described hydraulic means comprises hydraulic cylinder, hydraulic stem, oil pipe, described hydraulic stem external part is provided with guide wheel, described guide wheel leans in described binding clip one end.
Further: described binding clip, hydraulic means all have two covers, be centrosymmetric distribution.
Further: inside described binding clip, be provided with anti-slop serrations.
Further: described floor is by bolt and described sleeve connection.
Further: the material of described sleeve is carbon steel, the material of described binding clip is alloy steel.
The utility model has the advantage of and add drilling tool clamping range, provide effective to drilling tool and support and locking, reduce human input, reduce security risk.Of the present utility modelly be also advantageous in that for convenience detach and maintenance, structure is simple, dependable performance.

Detailed description of the invention
A kind of rat hole drilling tool clamping device, as shown in Figure 1, 2, comprises sleeve 1, binding clip 2, hydraulic means 3, described sleeve 1 upper end is provided with anchor ring 11, and for binding clip 2 provides support, described sleeve 1 lower end is provided with flange 12, can be connected and fixed by bolt, convenient disassembly.Described flange 12 external diameter is greater than described anchor ring 11 external diameter, effectively improves overall stability.Described binding clip 2 is arranged on described anchor ring 11 upper end by cylindricality hinge 4, replaces traditional rectilinear motion with rotary motion, simplifies structure, reduces maintenance difficulty.Described cylindricality hinge 4 inside is provided with main spring 41, forms certain rotary torque, is set back by binding clip 2 in time.Described hydraulic means 3 comprises hydraulic cylinder 31, hydraulic stem 32, oil pipe 33, described hydraulic stem 32 external part is provided with guide wheel 5, described guide wheel 5 leans in described binding clip 2 one end, carries out holding action, provide clamping force by the cooperation promotion binding clip 2 of hydraulic stem 32 and guide wheel 5.Described hydraulic means is fixed on described sleeve 1 side by floor 6, simplifies complicated fixed structure, effectively improves the degree of stability of hydraulic means 3.
Described binding clip 2, hydraulic means 3 all have two covers, and be centrosymmetric distribution, forms uniform chucking power to drilling tool.Be provided with anti-slop serrations 21, increasing friction force inside described binding clip 2, avoid the phenomenon occurring that screwed connection is not in place.Described floor 6 is connected with described sleeve 1 by bolt, is easy to remove and repair, and reduces working strength.The material of described sleeve 1 is carbon steel, the material of described binding clip 2 is alloy steel, reasonable utilization of materials, and bulk strength is reliable, function admirable.
Above-described embodiment, just in order to technical conceive of the present utility model and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.The change of every equivalence done by the essence of the utility model content or modification, all should be encompassed in protection domain of the present utility model.
