Abstract
The utility model relates to the field of slings, and in particular relates to a spring type safety elevator pin. The spring type safety elevator pin is characterized by comprising a pin body, an annular lug and a spring clip, wherein the annular lug is hinged with one end of the pin body; the spring clip is arranged on the pin body; the length of the pin body defined by the spring clip is greater than the maximum width of the elevator; the spring clip comprises a fixed handle knob, a torsional spring, a movable handle knob and a pin shaft; the middles of the fixed handle knob and the movable handle knob are hinged through the pin shaft; the torsional spring is arranged between the fixed handle knob and the movable handle knob; one end of the fixed handle knob is connected with the side pin body of the annular lug; one end of the movable handle knob is contacted with the other side of the pin body; and one end of the movable handle knob is provided with an arc gap matched with the pin body. Compared with the prior art, the spring type safety elevator pin has the beneficial effects that the elevator pin is safe, reliable and convenient to operate, so that the elevator and the lifting ring are reliably connected, the lifting operation of an oil pipe is convenient, the production safety coefficient is improved, the working efficiency can be effectively improved, and the labor intensity is lightened.
Description
Technical field
The utility model relates to the suspender field, relates in particular to a kind of spring type safety elevator pin.
Background technology
In the oil field operation process; The lifting oil pipe often needs elevator and suspension ring to cooperate suspension hook to carry out; Elevator passes the elevator hole with suspension ring by the elevator pin and is connected, and make because mostly the elevator pin is iron staff, and the friction between the elevator is little; The elevator pin can very easily be deviate from by play in elevator in the oil pipe lifting process, causes the oil pipe falling accident.
Summary of the invention
The purpose of the utility model provides a kind of spring type safety elevator pin, overcomes the deficiency of prior art, makes elevator more reliable with being connected of suspension ring, makes things convenient for the handling operation, improves the production safety coefficient.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of spring type safety elevator pin comprises shank, ring ear and spring clip, and the ring ear is articulated in an end of shank, and shank is provided with spring clip, and the length that shank is impaled by spring clip is greater than the width maximum value of elevator.
Said spring clip comprise fixedly handle knob, torsion spring, activity is handled knob and bearing pin; Fixedly handle knob with activity handle knob the middle part through bearing pin hinged; Fixedly handle knob and activity is provided with torsion spring between handling knob; One end of fixedly handling knob links to each other with ring ear side shank, and the end that activity is handled knob contacts with shank opposite side surface.
The end that said activity is handled knob is provided with the arc notch with the shank coupling.
Compared with prior art, the beneficial effect of the utility model is: safe and reliable and easy to operate, and make elevator more reliable with being connected of suspension ring, make things convenient for oil pipe handling operation, improve the production safety coefficient, can increase work efficiency effectively, reduce labor intensity.

The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2; It is the structural representation of a kind of spring type safety elevator of the utility model pin embodiment; Comprise shank 1, ring ear 2 and spring clip 3; Ring ear 2 is articulated in an end of shank 1, and shank 1 is provided with spring clip 3, and the length that shank 1 is impaled by spring clip 3 is greater than the width maximum value of elevator 4.
See Fig. 3, during lifting, the ring ear with safety jaw bayonet lock 12 connects with chainlet and suspension ring 10 earlier; Prevent that safety jaw bayonet lock 12 from coming off; Grasping fixedly handles knob again handles knob with activity, and activity is handled knob and opened after stressed, shank is pierced in the hole of elevator 4; Elevator 4 grasps the end of oil pipe 13, and suspension hook 11 is mentioned suspension ring 10 and got final product.
