Abstract
The utility model relates to the technical field of petroleum assembling and disassembling machines, in particular to an ultra short distance clamping mechanism for a makeup and breakout unit. The ultra short distance clamping mechanism comprises a support and a hydraulic cylinder. A connecting lug is fixedly arranged on the right side of the support, the hydraulic cylinder is fixedly arranged in the center of the support, the bottom of the hydraulic cylinder is fixedly connected with one end of a connector through a screw, the other end of the connector is hinged to one end of a first connecting rod through a pin shaft, the other end of the first connecting rod is hinged to a jaw plate assembly through a pin shaft, a plurality of adjusting holes are formed in the middle of the first connecting rod, the adjusting holes are hinged to one end of a second connecting rod through a pin shaft, and the other end of the second connecting rod is hinged to the connecting lug through a pin shaft. When the ultra short distance clamping mechanism for the makeup and breakout unit is used, the clamping distance between a main wrench and a back-up wrench is small and can be reduced to be 5 mm, the clamping positions and lengths of some parts are controllable, the labor cost is reduced, and the outer surfaces of some tools are protected against damage. The ultra short distance clamping mechanism for the makeup and breakout unit has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to oil dismounting field of mechanical technique, particularly a kind of thread screw on and-off machine very-short-reach clamp mechanism.
Background technology
Thread screw on and-off machine is a kind of threaded connector loading mechanization, is mainly applicable to oil field well pump, downhole tool, and oil pick-up tube oil pipe, turning of other threaded connectors such as pipe box joined and dismounting.
Existing thread screw on and-off machine structure is mainly made up of main pincers and back-up tong, back-up tong is clamped body and is not rotated, main clamp body rotation, between body and body, be threaded, owing to being subject to the restriction such as main pincers, back-up tong side plate thickness, main, that back-up tong clamps spacing is large, generally all reach more than 150 millimeters, due to drill and petroleum extraction tools (as: packer, sand preventing tool etc.) structure relative compact, component are irregular, when dismounting, need main, that back-up tong clamps spacing is less, indivedual component can clamped position and length limited, existing thread screw on and-off machine can't meet the demands in the market.
Therefore,, based on the problems referred to above, be necessary to provide a kind of thread screw on and-off machine very-short-reach clamp mechanism.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, thread screw on and-off machine reasonable in design, easy to use very-short-reach clamp mechanism.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of thread screw on and-off machine very-short-reach clamp mechanism described in the utility model, include support, hydraulic cylinder, connector, connecting rod one, connecting rod two and Hubei Province plate assembly, described support right side is fixedly installed engaging lug, described support centre is fixedly installed hydraulic cylinder, described hydraulic cylinder bottom is fixedly connected by screw and connector one end, and the connector other end is hinged by one end of bearing pin and connecting rod one; The other end of connecting rod one is hinged by bearing pin and Hubei Province plate assembly, and connecting rod one middle part is provided with several adjustment holes, and described adjustment hole is hinged by bearing pin and connecting rod two one end, and connecting rod two other ends are hinged by bearing pin and engaging lug.
As a kind of optimal way of the present utility model, the quantity of described adjustment hole is three.
As a kind of optimal way of the present utility model, the two ends of described bearing pin are all arranged with circlip for shaft.
As a kind of optimal way of the present utility model, described screw is also nested with spring washer, and spring washer is arranged between hydraulic cylinder bottom and connector.
Adopt after said structure, the utility model beneficial effect is: a kind of thread screw on and-off machine very-short-reach clamp mechanism described in the utility model, include support, hydraulic cylinder, connector, connecting rod one, connecting rod two and Hubei Province plate assembly, described support right side is fixedly installed engaging lug, described support centre is fixedly installed hydraulic cylinder, described hydraulic cylinder bottom is fixedly connected by screw and connector one end, and the connector other end is hinged by one end of bearing pin and connecting rod one; The other end of connecting rod one is hinged by bearing pin and Hubei Province plate assembly, and connecting rod one middle part is provided with several adjustment holes, and described adjustment hole is hinged by bearing pin and connecting rod two one end, and connecting rod two other ends are hinged by bearing pin and engaging lug.Using when the utility model, master while having solved dismounting, that back-up tong clamps spacing is little, and this spacing can be contracted to 5 millimeters; Having solved indivedual component can clamped position and the problem of the controllability of length, has saved cost of labor, has protected some tool exterior surface not to be damaged.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
