Abstract

The utility model relates to an automatic mechanical pincer device, belonging to the oilfield drilling equipment technical field and including a pincer seat, a pincer jaw, a single connecting rod, a double connecting rod, an oil cylinder, a spring seat and a plunger; one end of the pincer seat is equipped with the pincer jaw; the tail end of the pincer jaw is equipped with the double connecting rod linked by the single connecting rod; the other end of the pincer seat is equipped with a spring seat and a pull rod; one end of the pull rod is fixedly connected with the single connecting rod and the other end of the pull rod is fixedly connected with the spring seat; and the oil cylinder and the plunger are arranged in the middle of the spring seat. When in work, the hydraulic oil pushes the plunger through the oil cylinder; when the thrust is higher than the tension of the spring, the pull rod, the single connecting rod and the double connecting rod are driven to move forward and the pincer jaw is opened; when thrust on the oil cylinder oil-return plunger is disappeared, the tension of the spring drives the pull rod, the double connecting rod and the pincer jaw to retract together so as to clamp the pincer jaw. The automatic mechanical pincer device solves the problems of poor automation degree of the conventional pincer, complicated operation and easy slip-off of the clamped objects, has characteristic of simple structure and safe and reliable use and is especially suitable for oil workover rig operation.

Description

A kind of automation gripping mechanism
Technical field:
The utility model relates to a kind of automation gripping mechanism, belongs to drilling-production equipment device technique field, oil field.
Background technology:
In the operation of oil drilling and repairing well, need clamp clamping drilling rod, bore very, drill string (being generally 2-3 root drilling rod links together) or oil pipe, so that fixing and/or move.Employed common clamp is to adopt spring and/or mechanical linkage to carry out clamping and/or operation now, and automaticity is poor, complicated operation, and labor strength is big.And now employed automatic clamp is to adopt oil cylinder to carry out clamping and/or operation, though handling good than common clamp, in case when break down in the liquid road, the easy landing of gripping object causes unnecessary loss.
Summary of the invention:
The purpose of this utility model is: provide a kind of use spring force to clamp, adopt oil cylinder control to unclamp, simple to operate, control easily, the firm and safe and reliable automation gripping mechanism of clamping.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of automation gripping mechanism, it is made of pincers seat, jaw, single connecting rod, double link, oil cylinder, spring base, plunger, sleeve pipe, end cap, it is characterized in that: an end of pincers seat is symmetry shape by pivot pin A jaw is installed, jaw end tail is equipped with double link by pivot pin C, interconnects by single connecting rod and pivot pin B between the double link; The other end inside of pincers seat is provided with spring base, spring is installed on it, the pincers seat wall of spring base one side is provided with sleeve pipe, pull bar is housed in it, and an end of pull bar is affixed by screw B and single connecting rod, and the other end and spring base are affixed, the spring base middle part is provided with oil cylinder, plunger is housed on the oil cylinder, and described oil cylinder is packed on the end cap by screw A, and end cap is packed on the pincers seat by screw A.
Advantage of the present utility model is:
This automation gripping mechanism uses spring masterpiece clamping force, when break down in the liquid road, still can clamp gripping object, and is therefore safe and reliable; When device is not worked, clamp gripping object by spring force, then can save the energy.This automation gripping mechanism adopts oil cylinder control to unclamp, and then therefore control realize the control automation easily easily.So existing clamp avoided by this automation gripping mechanism or automaticity is poor, complicated operation, or the easy landing of gripping object, cause problems such as unnecessary loss easily.And have characteristics simple in structure, easy to operate, that control is easy, safe and reliable.Be specially adapted to use in the operation of oil drilling and repairing well.
Description of drawings:
Fig. 1 is the clamped condition structural representation of automation gripping mechanism;
Fig. 2 is the open configuration structural representation of automation gripping mechanism.
Among the figure: 1, jaw, 2, pivot pin A, 3, single connecting rod, 4, pivot pin B, 5, pivot pin C, 6, double link, 7, spring, 8, pull bar, 9, spring base, 10, end cap, 11, screw A, 12, oil cylinder, 13, plunger, 14, pincers seats, 15, sleeve pipe, 16, screw B, 17, gripping object.
The specific embodiment:
This automation gripping mechanism is made of jaw 1, single connecting rod 3, double link 6, spring base 9, end cap 10, oil cylinder 12, plunger 13, pincers seat 14 and sleeve pipe 15.One end of pincers seat 14 is symmetry shape by pivot pin A2 jaw 1 is installed, and the end tail of jaw 1 is equipped with double link 6 by pivot pin C5, interconnects by single connecting rod 3 and pivot pin B4 between the double link 6.The other end inside of pincers seat 14 is provided with spring base 9, and spring 7 is installed on the spring base 9.The pincers seat wall of the pincers seat 14 of spring base 9 one sides is provided with sleeve pipe 15, pull bar 8 is housed in the sleeve pipe 15, and an end of pull bar 8 is affixed by screw B16 and single connecting rod 3, and the other end and spring base 9 are affixed, the middle part of spring base 9 is provided with oil cylinder 12, and plunger 13 is housed on the oil cylinder 12.Oil cylinder 12 is packed on the end cap 10 by screw A11, and end cap 10 is packed on the pincers seat 14 (referring to accompanying drawing 1-2) by screw A11 again.
During this automation gripping mechanism work, hydraulic oil is given plunger 13 thrusts by oil cylinder 12, when this thrust is bigger than the tension force of spring 7,13 pushing drawing rods 8 of plunger travel forward, pull bar 8 promptly drives single connecting rod 3 and double link 6 motions, double link 6 drives jaw 1 motion again, and this moment, jaw was opened, and unclamped gripping object 17 (referring to accompanying drawing 2).When oil cylinder 12 oil returns, hydraulic oil in the oil cylinder 12 disappears for the thrust of plunger 13, this moment, the tension force of spring 7 made plunger 13 retractions, did serial retracting motion together thereby drive pull bar 8, single connecting rod 3, double link 6 and jaw 1, and made jaw that gripping object 17 is clamped (referring to accompanying drawing 1).This device uses spring force to clamp, and adopts oil cylinder control to unclamp, and has characteristics simple in structure, easy to operate, that control is easy, safe and reliable.Avoided existing clamp automaticity poor, the easy landing of complicated operation and gripping object causes the problem of unnecessary loss; Be specially adapted to use in the operation of oil drilling and repairing well.
