Abstract

An automatic circling drilling machine is characterized in that the automatic circling drilling machine is controlled by a remote controller and is provided with a crawler-type or walking type pile driver chassis, a rack platform and a column, wherein a power head is hung on the column; a rotary table where four drill rods can be perpendicularly placed is arranged on each side of the column; and a winch, a hydraulic pump station and a control cabinet which are used for hoisting the power head and lifting a pile frame as well as matched drill rods are arranged on the rack platform. Compared with the prior art, the automatic circling drilling machine has the advantages as follows: the number of workers on site can be greatly reduced, the labor intensity of the workers is reduced, and the construction speed is increased.

Description

A kind of rig that circles round automatically

Technical field

The utility model relates to the constructional engineering machinery field, relates in particular to a kind of rig that circles round automatically.

Background technology

Reformed and opened up to the outside world 30 years, China's infrastructure scale constantly enlarges, enter 2010, labor wage rises steadily, and especially in the construction work pile foundation construction building site that will expose to the weather, labour cost constantly rises, workman's odd-numbered day wage rises to 200-300 unit, and, more than be first generation rural migrant worker, the age is more than 45 years old.And present young workman select the hilllock many with comfortable, labour intensity is little, environment is excellent is the most important condition.Therefore, the bored pile construction automation of routine being circled round reduces the site operation number, reduces labor strength, is the Future Development inexorable trend.

The utility model content

The utility model provides a kind of rig and job practices thereof of circling round automatically, can only need 1 workman to hold the remote controller operation in the pile foundation engineering construction, just can finish the drilling pouring pile hole of the long 20-100m of stake.

The technical solution adopted in the utility model is: a kind of rig that circles round automatically, it is characterized in that what Yong Away control device was regulated and control, have crawler type or walking stake machine chassis, framework platform, column, hang with unit head at column, the rotating disk that can vertically stand up 4 drilling rods is respectively arranged in the column both sides, framework platform is provided with hoist engine, hydraulic power unit, the switch board that hangs unit head and rise and fall pile frame be used to opening, and supporting drilling rod.

A kind ofly circle round rig automatically compared with prior art, have obvious superiority: can significantly reduce the field worker number and reduce working strength of workers, improve speed of application.

The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.

Drawing explanation: 1. pulley, 2. back timber, 3. column, 4. wire rope, 5. drilling rod rotating disk, 6. leading block, 7. a frame oil cylinder, 8. hoist engine, 9. framework platform, 10. hydraulic power unit, 11. the tail support, 12. hydraulic pressure, 13. supporting legs, 14. switch boards, 15. drill bit, 16. lower contacts, 17. holding tube devices, 18. oil motors, 19. send the slurry pipe, 20. drilling rods, 21. top connections, 22. unit head gearboxes, 23. the unit head motor, 24. unit head pulleys, 25. workbench, 26. open heavy suspension hook arm.

The specific embodiment

As shown in Figure 1: a kind of concrete implementation step of the rig that circles round automatically is as follows:

1., each parts of rig that will circle round automatically are transported to the job site and install, and comprise the wire rope of putting on the column (3) (4), column (3) lower end links to each other with framework platform (9) with a pin, on the tail support (11) that lies low on the column (3);

2., start hydraulic power unit (10) on the rig with remote controller, sent hydraulic oil to frame oil cylinder (7), with column (3) top to upright, again in upright column (3) lower end with fixedly pin and framework platform (9) lock.

3., start drilling rod rotating disk (5) on the rig with remote controller, make it to rotate, forward drilling rod (20) to unit head (22,23) lower end, start unit head motor (23), hand over fast case (22) by unit head, by screwing last interface (21) and suitable for reading connection of drilling rod (20);

4., start the oil motor (18) of holding tube device (17) with remote controller, drive holding tube device (17) drilling rod (20) is blocked from rotating disk (5), remove rotating disk (5) again;

5., end interface (16) connects drill bit (15) under the drilling rod (20);

⑥, Away control device starts unit head motor (23), by gearbox (22) and drilling rod (20), drives drill bit (15) and rotates.Simultaneously, with slush pump with clear water or mud from sending the center cavity of slurry pipe (19) through drilling rod (20), flow out from drill bit (15) is most advanced and sophisticated, when drill bit (15) when creeping into, the alloy knife stirring on the drill bit (15), cutting, fragmentation soil layer and ovum gravel,

Take clod, fragmentary debris out of aperture, bored until this joint drilling rod (20);

7., turn back to 4., 5., 6. step, continue to add, spreading drilling rod (20) creeps into, continue to creep into to design elevation;

8., upwards carry a joint drilling rod (20), end interface (16) card is firm down with drilling rod (20) with holding tube device (17), unit head motor (23) backward rotation, and last interface (21) unclamps drilling rod (20), and block drilling rod (20) by holding tube device (17), be put on the drilling rod rotating disk (5);

9., by that analogy, finish the demolition that respectively saves drilling rod (20) in the hole, and vertically stand up on drilling rod rotating disk (5), drill bit (15) also unloads in ground;

10., regulation and control column upper end open heavy suspension hook arm (26) and suspension hook down thereof, the reinforcing cage of slinging connects by the economize on electricity weldering by prior art, and puts into the hole;

By 4., 5. step, again drilling rod (20) is connected at the bottom of the hole, and from sending slurry pipe (19) to send clean plasm through drilling rod (20) center cavity clear hole at the bottom of the hole;

The carrier pipe of concrete mixer is received on the aperture drilling rod (20), and concrete is at the bottom of the center cavity of drilling rod (20) falls to the hole, and drilling rod (20) is improved on limit perfusion, limit, and by joint demolition drilling rod (20), namely finishes a Bored Pile Construction.

Claims

1. rig that circles round automatically, it is characterized in that what Yong Away control device was regulated and control, have crawler type or walking stake machine chassis, framework platform, column, hang with unit head at column, the rotating disk that can vertically stand up 4 drilling rods is respectively arranged in the column both sides, framework platform is provided with hoist engine, hydraulic power unit, the switch board that hangs unit head and rise and fall pile frame be used to opening, and supporting drilling rod.
