Abstract

A novel spanner of an oil well for oil extraction well of an oil field or for pipe connection comprises a spanner body, a locking plate fixing device, a resetting spring and a locking plate, wherein the locking fixing device is arranged in the center of the line end of the spanner body which is fixed on and connected with the locking plate fixing device by a pin, and the locking plate which is penetrated into a center groove of the spanner body is fixed by the locking plate fixing device, then the resetting spring which is arranged on the rear end of the locking plate is pressed into a spring groove at the rear end of the locking plate. The problems of the current technique which are that the dissembling and assembling of the oil well or the pipe line using a moving or a box spanner is labor wasting and human being hurt is happened constantly, further when leakage of the steam inflow-outflow well is happened or a well blowout is happened, the processing is difficult are overcame by the utility model. The novel spanner of an oil well is capable of being used in oil extraction well of an oil field or in pipe connection work.

Description

The novel spanner of a kind of oil well

Technical field:

The utility model relates to the novel spanner of a kind of oil well of a kind of oil well mouth or pipeline connection usefulness.

Background technology:

At present in the job site, oil field, often the spanner that uses has monkey wrench and box spanner two classes, both in use are that demolition, installation well head and pipeline all need two people to pound tightly or break, not only waste the labour, and exist potential safety hazard, often occur in and pound in the well head process sledgehammer phenomenon of hurting sb.'s feelings, if steam-stimulated well well head leakage or the blowout workmen is taken place be difficult to pre-treatment; The low general spanner of well head also is difficult to handle.

The utility model content:

The purpose of this utility model is to provide a kind of oil well novel spanner, this novel spanner has solved the activity or the box spanner frequent phenomenon of hurting sb.'s feelings when demolition, installation well head or pipeline that exist in the prior art and has also wasted the labour, the problem that is difficult to pre-treatment when steam-stimulated well leakage or generation blowout.

The technical scheme that its technical problem that solves the utility model adopts is: the novel spanner of a kind of oil well is made up of wrench body, locking plate fixture, restoring spring, locking plate; Be provided with the locking plate fixture at the center of wrench body rectilinear end, wrench body is fixedlyed connected with pin with the locking plate fixture, locking plate is penetrated in the central channel of wrench body and fix, be provided with restoring spring in the locking plate rear end, and it is squeezed in the spring groove of locking plate rear end with the locking plate fixture.When the novel spanner of a kind of oil well is worked, when demolition, installation well head screw, the hexagonal hole of wrench body bottom directly is enclosed within on the nut of well head screw, locking plate is inserted in up and down between the Flange Plane, with general utility wrench outward winding or tighten connecting screw in addition the nut of end get final product, outer zip sheet fixture is taken off spanner; During demolition, installation flange connecting screw, the hexagonal hole of wrench body bottom directly is enclosed within on the head or nut of connecting screw, locking plate is inserted between two Flange Plane, and outwarding winding or tighten other nut of end of connecting screw with general utility wrench gets final product, and outer zip sheet fixture is taken off spanner.

The beneficial effects of the utility model are, simple in structure, easy to operate, safety, cost are low, reduce the execute-in-place working strength of workers, annotate the leakage of vapour well head and rob blowout easy to operate.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.Fig. 2 is the utility model locking plate fixture schematic diagram.

Among the figure: 1, wrench body, 2, the locking plate fixture, 3, restoring spring, 4, locking plate.

The specific embodiment:

The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.

As shown in the figure, the novel spanner of a kind of oil well is made up of wrench body 1, locking plate fixture 2, restoring spring 3, locking plate 4, center at wrench body 1 rectilinear end is provided with locking plate fixture 2, wrench body 1 is fixedlyed connected with locking plate fixture 2 usefulness pins, locking plate 4 is penetrated in the central channel of wrench body 1 fixing with locking plate fixture 2, be provided with restoring spring 3 in locking plate 4 rear ends, and it is squeezed in the spring groove of locking plate 4 rear ends.
