The size of opening is more slightly larger than slip insert box, facilitates slip insert box to install and occurs without again space, and opening is in both sides steel plate
Center, the most each reserved about 5cm.
Semicircle is processed on described connecting plate top, has boring in the middle of described semi-circular portion, is used for lifting.Described connection
The height of plate top semi-circular portion is higher than described two blocks of side plates with oblong openings.
Be provided with a diameter at described slip spider base plate center more than the semicircle of working string box cupling diameter, described semicircle with
The fluting making base plate U-shaped combines, and right-angle side is parallel with base, and grooving upper and lower side all does 60 ° of chamfered.
On described lifting machine rotation tubing string stationary slip device pedestal, there is fixed bolt hole to be connected to working rig
Together.On described lifting machine rotation tubing string stationary slip device pedestal, there is suspension centre can conveniently install.
Peace when the U-type groove opening of described lifting machine rotation tubing string stationary slip device pedestal side has pipe string in facilitating well
Dress.
Slip spider is linked together with radially load-bearing slips by bolt.The card of suitable string size is placed in slip insert seat
Watt tooth, clamps tubing string such that it is able to realize the axial chucking power of tubing string by the connecting bolt of fastening slip insert box.
Lifting machine rotates the edge of tubing string stationary slip device can do Passivation Treatment, prevents appearance the sharpest keen to operator
Member produces unsafe factor.Bonderizing is done on the surface rotating tubing string stationary slip device, prevents because of liquid corrosion corrosion.
For same lifting machine, rotating tubing string stationary slip device external shape and be basically unchanged, its size can basis
The tubing string being suitable for is different and changes.Described lifting machine rotates size and the working string phase of tubing string stationary slip device slips
Join.
This utility model is further to a kind of lifting machine, it is characterised in that: it is provided with on its Operating Pressure lifting equipment
Rotation tubing string stationary slip device of the present utility model.
This utility model rotates tubing string stationary slip device and avoids in prior art lifting machine owing to not rotating tubing string
Stationary slip device, causes cannot existing in constructing or constructing a lot of drawback and potential safety hazard in some bores the technique such as mill
Problem.
