Abstract
The utility model relates to a well equipment's part is repaiied to the brill for brill workover rig derrick plays to rise two long hydraulic cylinders to be right, promptly bore workover rig derrick and play to rise biliquid jar righting device. It is including installing side centralizing bracket, the middle part centralizing bracket in derrick lower part of the body both sides, and bearing frame and derrick lower part of the body 7 swing joint are passed through with hydraulic cylinder contact department for circular arc cover face, middle part centralizing bracket and every side centralizing bracket in middle part centralizing bracket both ends and every side centralizing bracket outer end, and middle part centralizing bracket and every side centralizing bracket have the tensioning spring. Play to rise the in -process at the two long hydraulic cylinders of derrick, integral type middle part centralizing bracket can reach the effect of rightting the biliquid jar simultaneously automatically under the effect of spring, and is reliable at manufacturing in -process simple structure, simple to operate, use.
Description
technical field
The utility model relates to a kind of parts of oil field drilling workover rig, for drilling and workover machines derrick lifting two long fluid cylinder righting, i.e. drilling and workover machines derrick lifting biliquid cylinder erection device.
Background technology
In the prior art, at 650 rank following drilling and workover machines derrick upper body extending cylinder Chang Weidan fluid cylinder, the erection device of whole long fluid cylinder is that two bracing frames clamp liquid cylinder piston under the action of the spring, reaches the effect of righting; In other drilling and workover machines of 750 higher levels, because tonnage is large, derrick is high, derrick upper body extending cylinder often adopts two hydraulic cylinder raising, and the erection device of two long fluid cylinders is generally 2 pairs of centralizing brackets and clamps liquid cylinder piston respectively under the action of the spring.Its shortcoming is that processing parts is many, and clamping force is not strong, installs complicated.
Utility model content
The purpose of this utility model provides a kind of structure simple, and clamping force strengthens, and installs simple drilling and workover machines derrick lifting biliquid cylinder erection device.
Technical solution of the present utility model is: drilling and workover machines derrick lifting biliquid cylinder erection device, it is characterized in that comprising the side centralizing bracket, the middle part centralizing bracket that are arranged on derrick lower body both sides, centralizing bracket two ends, middle part and centralizing bracket outer end, each side and fluid cylinder contact position are that circular arc overlaps face, middle part centralizing bracket and each side centralizing bracket are flexibly connected with derrick lower body 7 by bearing support, and middle part centralizing bracket and each side centralizing bracket are with tensioning spring.
The utility model has the advantages that: in the two long hydraulic cylinder raising process of derrick, in the middle part of integral type, centralizing bracket under the action of the spring, automatically can reach the effect of the biliquid of righting simultaneously cylinder, and in processing and manufacturing process, structure is simple, easy for installation, use is reliable.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is utility model works status architecture sketch.
Fig. 2 is Fig. 1 plan structure sketch.
Fig. 3 is both end sides centralizing bracket off working state structure diagram.
Fig. 4 is middle part centralizing bracket off working state structure diagram.
Detailed description of the invention
See Fig. 1,2,3,4, component title is as follows: fluid cylinder 1, bearing support 2, side centralizing bracket 3, spring 4, middle part centralizing bracket 5, derrick upper body 6, derrick lower body 7, liquid cylinder piston 8.
See Fig. 1-4, drilling and workover machines derrick lifting biliquid cylinder erection device righting schematic diagram, comprise the two long fluid cylinder 1 be arranged on derrick lower body 7, fluid cylinder 1 one end is fixed on the fluid cylinder beam of derrick upper body 6, the other end is fixed on derrick lower body 7 fluid cylinder beam, utilize hydraulic oil to promote liquid cylinder piston, derrick upper body 6 is moved back and forth in derrick lower body 7.Under off working state, fluid cylinder 1 piston contracts inside cylinder sleeve, and now derrick upper body 6 is in derrick lower body 7.Side centralizing bracket 3 and middle part centralizing bracket 5 are fixed on derrick lower body 7 framework by bearing support 2.On the downside of off working state, centralizing bracket 3 is at the large leg outer side in side, derrick upper body 6, middle part centralizing bracket 5 utilizes the limiting plate being arranged on derrick upper body 6 to be limited in derrick lower body 7 bottom, when derrick upper body 6 moves upward under the effect of biliquid cylinder 1, under the tensile force effect of spring 4, side centralizing bracket 3 moves inwards, and middle part centralizing bracket 5 moves upward, when departing from limiting plate, clamping biliquid cylinder 1 piston, moving axially of restriction liquid cylinder piston, reaches the effect of righting fluid cylinder 1.When derrick upper body 6 moves downward, reposition under the effect of side centralizing bracket 3 and middle part centralizing bracket 5 side thigh and limiting plate on derrick.
