Description

Rig substructure adjustable type movement socket

Technical field

The utility model belongs to technical field of petroleum machinery, is related to a kind of rig substructure adjustable type movement socket.

Background technology

Base movement socket is designed to meet the Integral transporting of petroleum rig base.Traditional base movement is dragged Seat, due to the restriction of rig substructure position of centre of gravity and movement socket tire capacity, base movement socket main body and base Relative position is relatively fixed, and the installation of wellhead blowout preventor is easily affected when base movement socket main body is in well head immediate vicinity Using and other shaft mouth operations.In addition, existing base movement socket main body and rig substructure side substantially with bolts Formula, the inefficiency, security when causing base movement socket to dismount be not high.

Utility model content

The purpose of this utility model is to provide a kind of rig substructure adjustable type movement socket, solves the shifting of prior art Fortune socket main body easily affects installing and using and other shaft mouth operations for wellhead assembly in base well head immediate vicinity, while Solve the problems, such as that movement socket main body is not high with the bolt connection dismounting inefficiency, security that rig substructure is commonly used.

The technical scheme that the utility model is adopted is that a kind of rig substructure adjustable type movement socket is included in rig The side of base lower surface four is provided with base support, well head direction of advance is provided with slideway in rig substructure lower surface, the slideway In movement socket main body is installed, be connected with regulation hydraulic pressure between one side fixed ear base and movement socket main body of rig substructure Cylinder；Movement socket main body is connected upwards with rig substructure using multigroup bearing pin, and multigroup bearing pin corresponds to respectively drillng operation position, moves Fortune position, each group of bearing pin is correspondingly arranged on a distribution organization, and all distribution organization are sequentially arranged in movement socket main body.

Rig substructure of the present utility model adjustable type movement socket, is further characterized in that：

Segmentation between movement socket main body and rig substructure is provided with carrying backing plate.

Slideway two ends are respectively arranged with a limited block.

The beneficial effects of the utility model are that simple structure is reasonable in design, not only meet the carrying of rig substructure movement socket Requirement, also with quick, safe movement function, movement socket main body can be made in drillng operation and base movement operation two Position adjustments, realize that movement socket main body avoids well head function, the more existing similar rig in structure and use during rig operation Base movement socket superiority is higher, adds the considerable demand of movement rig, and application prospect is boundless.

In figure, hydraulic cylinder is 1. adjusted, 2. limited block, 3. distribution organization, 4. movement socket main body, 5. carry backing plate, 6. bored Machine base, 7. base support.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is to be included in the side of 6 lower surface of rig substructure four to be provided with bottom Seat supports 7, slideway is provided with the lower surface of rig substructure 6 along well head direction of advance, and the slideway two ends are respectively arranged with a limit Position block 2, is provided with movement socket main body 4, between one side fixed ear base and movement socket main body 4 of rig substructure 6 in the slideway It is connected with regulation hydraulic cylinder 1；Movement socket main body 4 is connected upwards with rig substructure 6 using multigroup bearing pin, and multigroup bearing pin is right respectively Drillng operation position, movement position, each group of bearing pin is answered to be correspondingly arranged on the distribution organization 3 of a pneumatic/hydraulic manipulation, own Distribution organization 3 is sequentially arranged in movement socket main body 4, and segmentation between movement socket main body 4 and rig substructure 6 is provided with bearing pads Plate 5.

The flexible of the piston rod of hydraulic cylinder 1 is adjusted, is promoted and slided between movement socket main body 4 and rig substructure 6, realize movement Socket main body 4 and the regulation of pithead position, adjust hydraulic cylinder 1 according to movement socket main body 4 and size, the weight of rig substructure 6 It is determined that, the specification of distribution organization 3, quantity determine according to the size of rig substructure 6, weight.

The operation principle of the utility model device is,

Movement position (keep left position) of the movement socket main body 4 in rig substructure 6, sees Fig. 1, and rig substructure 6 is installed to Behind position, put down each base and support 7, together jacking makes movement socket by rig substructure 6 and movement socket main body 4 for base support 7 Main body 4 is not carried；Distribution organization 3 in movement socket main body 4 will connect between movement socket main body 4 and rig substructure 6 Pin axle is exited (unblock), is adjusted the piston rod of hydraulic cylinder 1 and is stretched out (well head direction) movement forward of promotion movement socket main body 4, when Move to behind the position of limited block 2 of right side (position of keeping right), adjust hydraulic cylinder 1 and stop stretching out；Distribution organization 3 is by movement socket main body Connect bearing pin ejection (locking) between 4 and rig substructure 6, movement socket main body 4 is locked with rig substructure 6 and no longer shifted, movement Socket main body 4 gets out of the way well head center, you can carry out drillng operation, sees Fig. 2 and Fig. 3；

After the completion of drillng operation, distribution organization 3 unlocks, and adjusting the action of hydraulic cylinder 1 makes movement socket main body 4 return to drilling well The movement position of base, packs up each base and supports 7, you can Integral transporting, sees Fig. 1.

Compact conformation of the present utility model, can not only realize the position in drillng operation and Integral transporting of movement socket main body 4 The regulation put, and the operating efficiency of movement socket main body dismounting adjustment can also be improved, while the work for reducing operating personnel is strong Degree.
