Abstract
The utility model relates to a mobile slide sleeve structure device for drilling machines for petroleum and seismic prospecting. The utility model comprises a lower joint (1), oil cylinders (2), a bearing (3), a pull ear (4), a check plate (5) and a slide sleeve (6), wherein the check plate (5) is provided with the oil cylinders (2), the lower joint is connected with a central pipe of a power head by threaded bolts, and the pull ear (4) is connected with the slide sleeve (6) through the bearing (3). Through the structure of double oil cylinders, the slide sleeve slides upwards and downwards, the connection and the replacement of drilling rods are rapid, convenient and safe, the labor intensity of borers are eased and safety hidden troubles are eliminated. Because the utility model is in the structure of double oil cylinders, the stress of the pull ear is symmetrical, force arm is small and every part has simple structure and easy processing and manufacture.
Description
Technical field:
The utility model is used for the oil seismic exploration rig, specifically, is a kind of motor-driven shift sleeve structure device.
Background technology:
Ago the seismic exploration rig connects and changes drilling rod and be generally manual operation with sliding sleeve, unloading the drilling rod operating process is, after the completion tool joint box is blocked, the Reverse Power head unloads pine with screw buckle between lower contact and tool joint box, decontrol chain, sliding sleeve slides along lower contact, blocks the shackle muscle in the tool joint box, then, promote unit head, block second tool joint box, the Reverse Power head, then can unload screw buckle between first and second drilling rod, transfer unit head, sliding sleeve is mentioned, hang up with chain, first drilling rod unloaded from unit head, finish the trip-out of first drilling rod.Pulling out of hole, the rest may be inferred for other drilling rods.From whole trip-out process we as can be seen, the sliding sleeve driller manually mentions and puts down, when in the sliding sleeve silt being arranged, slip ratio is harder, need use hammer sometimes and beat, in addition, the driller handles when very fast, sometimes driller's hand is squeezed and hinders, and brings potential safety hazard.
Summary of the invention:
The purpose of this utility model is to provide a kind of easy, reliable motor-driven shift sleeve structure, alleviates driller's labour intensity, avoids the motor-driven shift sleeve structure device of potential safety hazard.
The utility model is achieved in that and comprises lower contact 1, oil cylinder 2, bearing 3, draws ear 4, check plate 5, sliding sleeve 6 that be equipped with oil cylinder 2 on the check plate 5, lower contact is connected by bolt with the unit head central tube, draws ear 4 to be connected with sliding sleeve 6 by bearing 3.
The utility model also adopts following technical scheme:
Adopt two oil cylinder 2 structures, realize that sliding sleeve 6 slides up and down.
Draw ear 4 and bearing 3 outer ring tight fits, bearing 3 inner rings and sliding sleeve 6 tight fits, lower contact 1 links to each other with sliding sleeve 6 by flat key.
Have elongated slot on the check plate 5.
Draw ear 4 necks to slide up and down in groove, sliding sleeve 6 and lower contact 1 are connected by slide key.
Advantage of the present utility model is: by two cylinder structures, realize that sliding sleeve slides up and down, make to connect that to change drilling rod efficient and convenient, safe and reliable, alleviated driller's labour intensity, eliminated potential safety hazard.
Owing to be two cylinder structures, draw the stressed symmetry of ear, the arm of force is less, and each part is simple in structure, is easy to processing and manufacturing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Structure as shown in the figure, the trip-out of drilling rod and unload description in brill process and the technical background, the mentioning and put down of sliding sleeve 6 just is by oil cylinder 2 controls.Wherein the effect of check plate 5 is, limits oil cylinder 2 and draw ear 4 to rotate when unit head rotates.Draw ear and bearing 3 outer ring tight fits, lower contact links to each other with sliding sleeve by flat key, during the unit head rotation, lower contact, sliding sleeve and bearing inner race rotate together, check plate 5, draw ear 4, oil cylinder 2 to keep motionless, flexible by hydraulic system driving oil cylinder 2, realize moving up and down of sliding sleeve 6.
Adopt two oil cylinder 2 structures, realize that sliding sleeve 6 slides up and down, make to connect that to change drilling rod efficient and convenient, safe and reliable.
The order of connection of motor-driven sliding sleeve 6: check plate 5 links to each other with the unit head housing, oil cylinder 2 links to each other with check plate 5, have elongated slot on the check plate 5, draw ear 4 necks in groove, to slide up and down, draw ear 4 and bearing 3 outer ring tight fits, bearing 3 inner rings and sliding sleeve 6 tight fits, sliding sleeve 6 and lower contact 1 are connected by slide key, and lower contact 1 is connected by bolt with the unit head central tube.
