The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1,2 only is a section on Mao Dao right side, and may there be the identical section of 3-4 group in a cat road; Fig. 4 only is part, right side, and the 3-4 group also may be arranged.

Referring to Fig. 1, Fig. 2, the structure of the utility model device is, be provided with at bilateral or one-sided power type cat road base 1 longitudinal center's line position and send drill string device 2, at the concordant seesaw 6 that is inlaid with of the panel of base 1 one or both sides, cat road, with reference to Fig. 4, seesaw 6 soffit two ends respectively are provided with an otic placode, and each otic placode is hinged by a bearing pin 5 and seesaw inclination fluid cylinder 4 piston terminations respectively, and the other end of seesaw inclination fluid cylinder 4 is hinged on the Connection Block of cat road base 1; Base 1 arranged outside has pipe rack 8 in the cat road, pipe rack 8 inner side edges are along hinged by the edge of bearing pin and cat road base 1, the outside of pipe rack 8 (other end) soffit is provided with main otic placode, this main otic placode and pipe rack inclination fluid cylinder 9 piston terminations are hinged, pipe rack inclination fluid cylinder 9 cylinder body bottoms are supported on the ground by shoe, and pipe rack 8 is in the state of being inclined upwardly all the time.

Referring to Fig. 3, the soffit of seesaw 6 is provided with two pin shaft hole otic placodes altogether, is used for grafting bearing pin 5, so that two seesaw inclination fluid cylinders 4 of seesaw 6 and below are hinged firm respectively; Wherein the pin shaft hole otic placode in the outside (near pipe rack 8) and seesaw 6 outer consubstantialities arrange, be called curved baffle 10, the outer side elevation of curved baffle 10 and seesaw 6 is arcwall face, and the radius of its radian is equivalent to seesaw 6 around the radius of gyration R in inboard (towards cat road base 1) lug plate holes axle center.

Referring to Fig. 4, stretch out outside the panel of cat road base 1 one sides the outer of seesaw 6, at the inner backing pin installing hole 11 that is provided with diverse location in base 1 outer, cat road, be used for installing backing pin 3, different backing pin installing holes 11 from the outer of seesaw 6 apart from difference, in suitable backing pin installing hole 11, backing pin 3 is installed, rolls on the seesaw 6 with the pipe that adapts to different-diameter.

Pipe rack 8 is in outside top heeling condition all the time, rely on action of gravitation, so that pipe 7 can inwardly roll (or slip), all pipes 7 are close to backing pin 3 outsides on the cat road base 1 all the time, because the effect of backing pin 3, guaranteeing can only have a pipe 7 to enter in seesaw 6 outers simultaneously, must remove backing pin 3 when pipe 7 rolls into pipe rack 8.

Device characteristic of the present utility model is that with seesaw 6 outer lateral layout camber shapes, arc core guarantees that at the center of rotation of seesaw 6 other ends arc surface is tangent with the external diameter of pipe 7 all the time.According to the pipe of different tube diameters, in cat road arranged outside the backing pin installing hole of diverse location is arranged, so that seesaw exceeds the backing pin part, just can place a pipe.

The method that dynamic catwalk pipe seesaw device of the present utility model carries out tubular load is to implement according to following steps:

When needs roll into pipe when sending drill string device 2 from pipe rack 8, the east side operation in Fig. 2 is described as example.

Step 1.1) initial position setting, seesaw 6 is in level, and pipe rack 8 is in the state that outside top tilts;

Step 1.2) the operation outside (right side) seesaw inclination fluid cylinder 4 pistons stretch out, seesaw inclination fluid cylinder 4 is around bearing pin 5 rotations in its inboard (left side), so that seesaw 6 outers rotation lifting, roll across the position of (perhaps crossing) backing pin 3 after placing lip-deep first pipe 7 in its outer to be raised to certain altitude, lean on gravity inertial to roll into send in the drill string device 2 always, in the lifting process, 7 curved baffles 10 by seesaw 6 outers of other pipe that rolls down on the pipe rack 8 block, and tangent with tube outer diameter, guarantee that can only have a pipe 7 to roll into send drill string device 2 at every turn;

Step 1.3) the operation outside (right side) seesaw inclination fluid cylinder 4 piston-retraction, when seesaw 6 was got back to level, curved baffle 10 was tangent with pipe 7 external diameters all the time, and only produced sliding friction between the pipe 7, can not promote remaining pipe 7 on the pipe rack 8, save the energy.In the whole operating process, pipe rack 8 certain angle that tilts all the time, pipe 7 can overcome friction roll or slide to seesaw 6 directions under this inclination angle.When seesaw 6 is repositioned to level, originally second pipe 7 that was blocked by curved baffle 10 rolls on the seesaw 6 automatically from the pipe rack 8 that tilts, the 3rd pipe 7 of being close to later can only come seesaw 6 outsides, and seesaw inclination fluid cylinder 4 is in initial armed state.

Step 1.4) repeat above-mentioned step 1.2), step 1.3), just the pipe 7 on the pipe rack 8 can be sent in the drill string device 2 one by one.

Device of the present utility model, by at the seesaw two ends hinge hole being set, the outer is designed with curved baffle, and curved baffle is tangent with tube outer diameter all the time, can automatically sort one by one pipe in the seesaw rotary course.Pipe rack is in the state of being inclined upwardly all the time, and the loading of pipe no longer needs the pipe rack that tilts back and forth, only relies on the pipe self gravitation to realize.Simple in structure, control is simple so that the tubular load process operation cycle shortens, energy consumption reduces, and has greatly improved pipe and has rolled into the efficient of sending the drill string device from pipe rack, reduces labor strength, economic benefit is very obvious.
