Detailed description of the invention
With reference to Fig. 1-Fig. 3, the safe elevator of protection, comprises elevator body 1 automatically; hanger is respectively equipped with in the left and right sides of elevator body 1; hanger and suspension ring removably connect, and hanger comprises hanger 2 and lower hanger 3, lower hanger 3 is all movably equipped with the suspension ring lock pin 4 for preventing suspension ring from coming off.
The upper surface and lower surface of elevator body 1 are installed with elevator upper cover plate 5 and elevator lower cover 6 respectively, and elevator upper cover plate 5 is fixed on the upper surface of elevator body 1 by fastening bolt and spring shim.Can be positioned in cannelure 8 valve 9 by elevator upper cover plate 5, restriction valve 9 and spring 10 up and down.
Elevator opening 7 place, top of elevator body 1 is provided with the cannelure 8 be arranged in parallel with elevator upper cover plate 5, is movably installed with between two valve, 9, two valve 9 and is connected with spring 10 in cannelure 8.Wherein, the groove 12 with inclined-plane 11 is arranged at the bottom of valve 9.The spring groove 20 for fixing spring 10 is equipped with at the link of valve 9.Two valve 9 can be controlled by spring 10 flexible to close or open.
Push rod group hole 13 is respectively equipped with in elevator opening 7 both sides of elevator body 1, be movably equipped with in push rod group hole 13 for the push rod group along groove 12 inclined-plane 11 movement, be fixed with movable erection device 14 in the bottom of push rod group, movable erection device 14 is positioned at the below of elevator lower cover 6.Wherein, movable erection device 14, for being fixed on the base plate bottom push rod group, can drive push rod group to move down by movable erection device 14, thus drives suspension ring lock pin 4 to move up.Realize the reciprocating motion of push rod group by moving up and down of movable erection device 14, and then realize the everything of elevator.In addition, push rod group comprises and is positioned at short push rod 18 bottom valve 9 and the long push rod 19 that be fixedly connected with parallel with short push rod 18, short push rod 18 is all fixedly connected with movable erection device 14 with the bottom of long push rod 19, driving lever 15 is arranged on the below of short push rod 18, and the top of long push rod 19 is moved along groove 12 inclined-plane 11
Push rod group is provided with the link gear moved up and down for controlling suspension ring lock pin 4.Wherein, link gear is positioned at the internal cavities of lower hanger 3, link gear comprises the driving lever 15 be positioned at below push rod group and the seesaw 16 be positioned at below driving lever 15, seesaw axle 17 is also provided with in lower hanger 3, interior seesaw 16 can be rotated by seesaw axle 17, one end of seesaw 16 and the lower contact of driving lever 15 like this, the other end is positioned at the below of suspension ring lock pin 4, like this by driving lever 15 press down and on lift, interior seesaw 16 can be controlled rotate around seesaw axle 17, thus moved up and down by the other end promotion suspension ring lock pin 4 of interior seesaw 16, thus close or open the hanger opening of suspension ring.
Operating principle:
When elevator body 1 is mentioned, after being separated with wellhead flange or job platform plane etc., under Action of Gravity Field and the effect of spring 10 tension force, push rod group is descending, and the driving lever 15 of push rod group bottom oppresses one end of interior seesaw 16 downwards, and interior seesaw 16 rotates around seesaw axle 17, according to lever principle, the other end of interior seesaw 16 then moves upward, and suspension ring lock pin 4 is released, risen, thus closes the hanger opening of suspension ring.While push rod group is descending, under the effect of spring 10, left and right valve 9 stretches out forward, closes elevator opening 7.When elevator body 1 is transferred, after movable erection device 14 i.e. base plate contacts with wellhead flange or job platform plane etc., under the Action of Gravity Field of elevator and oil pipe, push rod group moves upward in elevator body 1, under being acted on by the slope 11 of the groove 12 in left and right valve 9, left and right valve 9 is pushed back and pressuring spring 10, open elevator opening 7, can oil pipe be shifted out.Suspension ring lock pin 4 is at self gravitation (or spring) falls downward simultaneously, opens the hanger opening of suspension ring, can extract suspension ring, carry out bottom operation.
Apparatus of the present invention are rational in infrastructure, automatically can complete all operations, intervene, can reduce operation without the need to personnel, save the activity duration, improve the operating speed of lower oil tube.The design of this Elevator structure is ingenious, and without other, electric or hydraulic pressure is assisted, and achieves best function with minimum economic input, this automatically protect safety jaw card structure rationally, dependable performance, greatly reduce accident rate.Therefore apply this technology, not only save cost of labor, improve operating efficiency, and add construction safety reliability.
The present invention is not limited to above-mentioned embodiment, and in the ken that those skilled in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept, the content after change still belongs to protection scope of the present invention.
