Abstract
The utility model discloses a there is not welded formula casing head base, casing head base, positioning bolt, locating rack, casing head support, casing head pad, hydraulic pressure lift post, control rod, hydraulic pump, be provided with the casing head pad on the casing head base, the casing head sets up on the casing head pad, wherein the casing head pad height can be adjusted by the hydraulic component that hydraulic pressure lift post, control rod and hydraulic pump are constituteed, with this position according to casing length control casing head, casing head support, locating rack and positioning bolt also can carry out spacing fixed to it according to the casing head position simultaneously, whole device simple structure, according to the accurate casing head position of adjusting of casing length, be applicable to the casing head installation under the multiple condition, the device simple installation simultaneously, the casing head damage problem that has avoided traditional welding installation to arouse appears.
Description
Technical Field
The utility model relates to a well head device field in the petroleum equipment, especially a there is not welded type casing head base.
Background
The casing head is when carrying out drilling operation, a well head equipment for supporting and fixed casing string in the pit, install the production tree after blowout preventer stack and the well completion, the casing head needs to have stable support at the in-process that sets up, in order to guarantee the continuous normal operating of relevant production equipment, consequently, the casing head needs to combine together with the casing head base in the installation, current common casing head base is mostly the welded type and installs on the casing head, accomplish high rigidity after the welding, lead to the condition that sleeve length needs to be maintained to the condition complicacy in the pit, be not convenient for carry out the positioning control to it, furthermore, welding operation can not avoid causing the influence to mechanical structure's intensity, arouse the emergence of welding seam fracture scheduling problem.
SUMMERY OF THE UTILITY MODEL
For solving the deficiencies of the prior art, the utility model provides a non-welding type casing head base.
The utility model provides a there is not welded type casing head base, the casing head sets up on the casing head base, the casing head base includes positioning bolt, locating rack, casing head support, casing head pad, hydraulic pressure lift post, control rod, hydraulic pump, the casing head pad sets up in the casing head below, hydraulic pressure lift post sets up on the casing head base, is connected with the casing head pad, the casing head support sets up on the casing head base, encircles the casing head pad, the locating rack sets up on the casing head support along the same shape to be connected with the casing head support through positioning bolt, the hydraulic pump sets up in casing head base one side, the control rod is connected with the hydraulic pump.
Furthermore, the bottom of the casing head base and the casing head cushion are of hollow structures, and the hollow diameter is larger than the diameter of the casing.
Furthermore, the casing head support is a hollow annular structure support, and the hollow diameter is slightly larger than the diameter of the bottom of the casing head.
The utility model has the advantages that:
1. through set up the casing head pad that is connected with hydraulic pressure mechanism on casing head base, utilize the casing head pad to support the casing head to make hydraulic pressure mechanism can adjust the high position of casing head according to sleeve pipe length, accommodation process convenient and fast avoids causing the damage to the casing head.
2. The casing head is limited by the casing head support, the positioning frame and the positioning bolt, the height position can be finely adjusted according to the position of the casing head, and the limiting installation effect on the casing head can be effectively achieved.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram of the construction of the casing head base;
in the figure, 1 casing head, 2 casing head bases, 3 positioning bolts, 4 positioning frames, 5 casing head supports, 6 casing head pads, 7 hydraulic lifting columns, 8 operating rods and 9 hydraulic pumps are arranged.
Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the present invention.
Example (b):
The utility model discloses when using, install casing head base 2 on the sleeve pipe, and install locating rack 4 on casing head support 5 through positioning bolt 3, later sit casing head 1 in the sleeve pipe, ensure slips straining sleeve pipe, utilize 8 control hydraulic pump 9 of control rod to annotate to hydraulic pressure lift post 7 and press, make casing head pad 6 rise to the slip of contact support casing head 1 bottom, later keep in most suitable high position according to casing length adjustment casing head pad 6, adjust positioning bolt 3 simultaneously, make the position laminating casing head 1 bottom of locating rack 4 peripheral, with guaranteeing casing head 1 rigidity, whole process is simple, and fast, can adjust casing head 1 position along with the change of casing position, application scope is extensive.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are all covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
