Description
Technical field
The utility model belongs to oil field drilling well workover mechanical field, particularly relates to a kind of suspension attachment.
Background technology
In oil field drilling workover treatment process, elevator is absolutely necessary suspension attachment, traditional elevator is open type elevator, valve has been installed, lock bolt has been installed, elevator in use will first open valve or lock bolt, main body can be opened, and what realize next step holds the function promoting tubing string.Traditional elevator can not realize upset as required in operation process.
Utility model content
For solving in existing oil field drilling workover treatment process, elevator needs to install valve or lock bolt, causes Elevator structure complicated, complex operation, and can not realize the problem overturn in operation process as required, the utility model provides a kind of imperforation formula elevator, and its technical scheme is as follows:
A kind of imperforation formula elevator, comprises slip spider, slip spider is provided with the upper centre bore and lower centre bore that are interconnected, upper centre bore is the bellmouth stood upside down, circumferentially uniformly in upper centre bore be provided with some pieces of slips bodies, slip spider top is provided with cover plate, it is characterized in that:
Described slip spider is provided with cylinder, the piston rod end on described cylinder is provided with top board, top board is fixedly connected with on the cover board, and cover plate is connected with slips body by connecting rod;
Also be provided with gathering sill outside described upper centre bore, upper centre bore is connected with gathering sill, is provided with guide peg in gathering sill, and the circular fairlead suit on slips body on the guide bar.
Preferably, described some pieces of slips bodies surround one for clamping the passage of the dumb-bell shape of tubing string, and described passage comprises the upper channel be communicated with successively, middle passage and lower channel, and wherein upper channel is in the taper of standing upside down, middle passage is cylindrical, and lower channel is upright taper.
Preferably, described lower centre bore is upright bellmouth.
Preferably, circumferentially uniformly in described upper centre bore four pieces or eight pieces of slips bodies are provided with.
Preferably, the tapering of described upper centre bore is 60 degree;
Inclination angle between guide peg and horizontal plane is 60 degree.
The utility model provides a kind of imperforation formula elevator not having valve or lock bolt, in use can towards a direction upset, and structure is simple, easy to operate, safely, reliably.
The utility model elevator is monolithic construction, does not have valve or lock bolt, in use can towards the upset of direction, and slips body is arranged in slip spider, and the phenomenon swung can not occur the situation lower slips body carrying out overturning at slip spider.Slips body is connected with cover plate and cylinder by connecting rod, is moved up and down thus drive slips body to move up and down by control cylinder, realizes the function holding, unclamp tubing string.
The beneficial effects of the utility model are:
Structure is simply novel, integral inclined certain angle can be made to hold tubing string, holding tubing string more convenient when holding tubing string, and operation slip spider realizes in the process of upset at the scene, and slips body the phenomenon that swings can not occur and affects and wholely hold operation process.Decrease installation simultaneously, dismantle and change the action of valve or lock bolt, use convenient, and the component of product are fewer than traditional elevator, improve operational security.
The utility model is in the process of elevator integrated overturn, and slips body and slip spider relative position are fixed, and the phenomenon that slips body arbitrarily swings can not occur.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is that A-A of the present utility model in Fig. 1 is to sectional view.
Detailed description of the invention
A kind of imperforation formula elevator as depicted in figs. 1 and 2, comprise slip spider 1, slip spider 1 is provided with the upper centre bore 7 and lower centre bore 8 that are interconnected, upper centre bore 7 is the bellmouth stood upside down, circumferentially uniformly in upper centre bore 7 be provided with four pieces of slips bodies 2, that is, described four pieces of slips bodies 2 with the axial line of described upper centre bore 7 for the center of circle, be centrosymmetric setting, and slip spider 1 top is provided with cover plate 4;
Described slip spider 1 is provided with cylinder, and piston rod 5 termination on described cylinder is provided with top board 6, and top board 6 is fixedly connected on cover plate 4, and cover plate 4 is connected with slips body 2 by connecting rod 3;
Gathering sill 9 is also provided with outside described upper centre bore 7, upper centre bore 7 is connected with gathering sill 9, be provided with guide peg 10 in gathering sill 9, the circular fairlead 11 on slips body 2 is sleeved on guide peg 10, and the gap between fairlead 11 and guide peg 10 is 0.8 millimeter.
Described four pieces of slips bodies 2 surround one for clamping the passage of the dumb-bell shape of tubing string, described passage comprises the upper channel 12, middle passage 13 and the lower channel 14 that are communicated with successively, wherein upper channel 12 is in the taper of standing upside down, and middle passage 13 is cylindrical, and lower channel 14 is in upright taper.
Described lower centre bore 8 is upright bellmouth, and the tapering of lower centre bore 8 is 75 degree.
