Abstract
The utility model relates to a pneumatic roller climbing type mouse hole calipers. According to the technical scheme, the calipers comprise an upper flange, a lower flange, a roller caliper head component and a pneumatic component. The roller caliper head component comprises a casing, studs and a slope board component. The casing is welded through a profile, and a cavity structure is formed inside. The slope board component is fixed in the cavity of the casing through the studs, an upper disc component and a lower disc component are connected by internal hexagonal bolts through connection columns and adjusting copper pads and are arranged in the cavity of the casing, and square grooves with caliper heads are arranged in the upper disc component and the lower disc component. The calipers have the advantages that an air cylinder drives the upper disc component and the lower disc component to drive the caliper heads to rotate in the casing, the caliper head component slides along the square grooves of the upper disc component and the lower disc component while rotating under the slope plate action to clamp a drill rod connecting hoop, the clamping has a self-lock function, the clamping torque is large, the drill rod is not prone to sliding during automatic drill rod fastening, and the pneumatic control is flexible and reliable.
Description
Technical field
The utility model relates to handler on a kind of oil drilling rat hole drilling tool, particularly a kind of pneumatic climbing roller formula rat hole clamp.
Background technology
In oil drilling work progress, at mouse hole, unloading single is all by manual operation, Duo Jia oil equipment manufactory designed, designed afterwards, also, from external several rat holes single device of unloading of having introduced, mainly contains clamp plate type, bias or climbing roller formula structure, pneumatic type rat hole clamp etc.But, these rat holes unload single device all because complex structure, volume are large, operation inconvenience, poor practicability, so all there is no fine popularization always.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of pneumatic climbing roller formula rat hole clamp are provided, and adopts pneumatic control, and binding clip climbing roller clamps, and the rat hole single automaticity of unloading is further provided, and has improved operating efficiency.
Its technical scheme is: comprise upper flange, lower flange, roller binding clip assembly, Pneumatic assembly, described roller binding clip assembly comprises housing, double-screw bolt, ramp assembly, housing is welded by section bar, inside is circular cavity structure, ramp assembly is fixed in the circular cavity of enclosure interior by double-screw bolt, upper dish assembly and lower wall assembly are by joint pin and regulate copper packing to link together with hexagon socket head cap screw, be arranged in the cavity of housing, upper dish assembly and lower wall assembly are processed with the square groove that binding clip is installed, roller binding clip assembly is arranged in the square groove of dish assembly and lower wall assembly,
Described Pneumatic assembly comprises cylinder, cylinder saddle, bolt, cylinder block, bolt, and cylinder is fixed by bolts to the cylinder block on housing by cylinder saddle, and cylinder piston rod is flexibly connected with upper dish assembly and lower wall assembly.
Four jiaos of above-mentioned housing are provided with circular damping sleeve.
The beneficial effects of the utility model are: cylinder drives upper dish assembly and lower wall Component driver binding clip to rotate in enclosure interior, binding clip assembly is under the effect of ramp, in the time of rotation, along upper dish assembly and lower wall assembly square groove, slide, reach the object that clamps drill pipe coupling, the clamping of this form has auto-lock function, and clamping torque is large, drilling rod is automatically gone up in button process and is difficult for skidding, pneumatic control flexibility and reliability.
