The specific embodiment

Below in conjunction with accompanying drawing seat of the present invention is further described:

Tube apparatus totally 2 pipe-kicking mechanisms are sent in the oil field, front and back are arranged in trailer longitudinal median plane position, and oil cylinder vertically is installed on trailer inside, and the action of two cylinders synchronously, single cylinder hoisting force F 〉=1750 kilograms, stroke L=320 millimeter, stops time length S=2 second at build up time S=3 second, reset time S=3 second, maximum speed is 0.11 meter per second, and two initial points have stroke limit up and down, and oil cylinder is double acting single-piston, floating-caliper brake rod-type hydraulic actuating cylinder (is oil cylinder pull back function).

The pipe-kicking mechanism of oil field pipe conveying device, it is made up of base plate 1, spring 2, voussoir 3, spring cotter 4, packing ring 5, bearing pin 6, guide rail 7, top board 8, gyration block 9, top 10, plunger 11, oil cylinder 12, slide block 13, cover plate 14, tube seat 15.Described guide rail 7, base plate 1 and voussoir 3 are welded as a whole, and are screwed in tube seat 15; Gyration block 9 is connected in the guide rail 7 with top board 8 usefulness bearing pins 6; Slide block 13, spring 2, voussoir 3 and cover plate 14 respectively are symmetrically set in top board 8 bottoms in twos; Top 10 is fixedly connected on oil cylinder 12 tops with plunger 11.

Oil cylinder 12 oil-feeds, plunger 11 upward movements, top 10 enters tube seat 15 and close gradually slide block 13, as shown in Figure 4.

Slide block 13 is backed down in top 10, enters in the top board 8, promotes to move on the top board 8; Slide block 13 will break away from voussoir 3 constraints gradually, under spring 2 thrusts, to mechanism's central slide.

Top board 8 will promote drilling pipe 16 and move near drilling pipe 16; Gyration block 9 is with moving on the top board 8 and being center steering with bearing pin 6, and its head arc surface is tangent with guide rail 7 or tube seat 15 all the time.

Top board 8 and gyration block 9 continue upwards to elect drilling pipe 16; Gyration block 9 is a center steering with bearing pin 16 under drilling pipe 16 pressure, and its head arc surface is close to tube seat 15 and is slided; Slide block 13 is stopped by plunger 11, stops to slide.

Drilling pipe 16 is moved on continuing by the election of top board 8 and gyration block 9, and outwards makes trace along top slope 8 inclined-planes with the revolution of gyration block 9 and roll.

Top board 8 is elected to end position, and gyration block 9 forms an outward-dipping inclined-plane, and drilling pipe 16 outwards rolls out along the inclined-plane, and mechanism plays the pipe action and finishes, as shown in Figure 5.

The oil cylinder oil return, plunger 11 moves downward, and top 10 will spur slide block moves down top board 8, as shown in Figure 6.

Gyration block moves down with top board 8 and turns round gradually and resets; Slide block 13 will be slided backward by voussoir 3 inclined-plane component.

Top 10, slide block 13 move in succession will be tangent with 8 inclined-planes, top until slide block 3 head chamferings.

Come directly towards 10 inclined-plane component greater than voussoir 13 inclined-plane resistances, make also to drive top board 8 when sliding to outer the slip and move down.

Slide block 13 perpendiculars and voussoir 3 perpendiculars are tangent, and slide block 13 stops to slide; Top 10 pulling slide blocks 13 make top board 8 continue to be displaced downwardly to base plate 1 place; Top board 8 is obstructed and stops to move down.

Plunger 11 pulling force are much larger than the suffered resistance in 10 inclined-planes, top, and slide block 13 is backed down in top 10, withdraws from tube seat 15, gets back to initial position with plunger 11, as shown in Figure 7.

This mechanism plays when managing, and gyration block 9 will be finished the election to drilling pipe 16 earlier, forms an inclined-plane that allows pipe fitting outwards roll gently then naturally, moves continuously, and transition is steady.

When mechanism resetted, oil cylinder plunger 11 stretchy mechanisms got back to initial position smoothly, and gyration block 9 can steadily with mechanism, safe reset.

After mechanism resetted, oil cylinder plunger 11 is releasing mechanism and away from tube seat 15 smoothly, and the space motion of tube seat 15 is not interfered.

Gyration block 9 and top board 8 are when off working state, and it act as fills the tube seat square hole, be not subjected to the square hole interference when drilling pipe 16 is vertically carried and pass through smoothly tube seat 15 in.

By changing oil cylinder stroke and element structure parameter, this mechanism is applicable to pipe fitting, the rod member load transfer device of different occasions, different platform, different tube seat, different size.
