Abstract
The utility model relates to a pneumatic chuck which is composed of two symmetrical clamping tile seats, two symmetrical semi-circular hanging discs, a plurality of clamping tile bodies, a cylinder, a guiding rod and connecting rod components. The two clamping tile seats are provided with symmetrical semi-circular conical faces respectively, the cylinder and the guiding rod are connected between the clamping tile seats and the hanging discs respectively through nuts, the clamping tile bodies are connected with the hanging discs through the connecting rod components, the rear portions off the clamping tile bodies are arranged in the semi-circular conical faces on the clamping tile seats, and the front portions of the clamping tile bodies are provided with conical faces. The pneumatic chuck is simple in structure, long in service life of a drill rod and capable of improving work efficiency and lowering labor intensity, up-going and down-going of the cylinder are utilized to drive the hanging discs to move, so that the connecting rod components on the hanging discs are used for driving the clamping tile bodies to move up and down along the conical faces, abrasion of the drill rod is little, and production cost is saved.
Description
Technical field
The utility model relate to a kind of in drilling engineering the unloading of well head drilling tool and the supporting adn fixing device when changing, relate in particular to a kind of air spider.
Background technology
In drilling process, changing drilling tool, processing accident etc. all needs to remove drilling rod, the unloading drilling rod ring that is absolutely necessary.At this moment, need a kind of instrument can be safely and reliably with all roofbolt load support more than the rig floor face, the button operation of screwing on again.In job site in the past, the various air operated slips that are patent disclosures of use are though structure is variant slightly, but principle all is the same, all is the power that provides by cylinder, produces radially clamping force, by the bigger screw die of hardness roofbolt is clamped, the extruding that screw die and roofbolt produce is squeezed drilling rod bad chewing, inevitably along with the degree of depth of well-digging is more and more darker, roofbolt is more and more longer, load is just increasing, and chucking power is also increasing, and the situation that crowded evil idea chews is also more serious.For this reason, after the technology of utility model patent ZL 200920037277.6 " a kind of drilling rod " was born, by improving, designing chuck a kind of simple in structure, safe and reliable was that realistic meaning is arranged very much.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, prolong the drilling rod life-span, increase work efficiency, reduce the air spider of labour intensity.
The technical solution of the utility model is: described chuck is made of the slip spider of two symmetries and semicircle appending disk and a plurality of slips body, cylinder, guide peg and the linkage component of two symmetries, be respectively equipped with the semicircle conical surface of symmetry on described two slip spiders, described cylinder and guide peg are connected between slip spider and the appending disk by nut respectively, described slips body is connected with appending disk by linkage component, described slips body rear portion is arranged in the semicircle conical surface on the slip spider, and described slips body front portion is provided with the conical surface.
The slip spider of described two symmetries removably connects, and two slip spiders are provided with the slot of putting into for contiguous block, and described two slip spiders are provided with the connection bearing pin and fixedly connected with the contiguous block two ends respectively.
Described linkage component comprises connecting rod, link pin and link pin fixed block, and described link pin is fixedly connected on the appending disk by the link pin fixed block, and described connecting rod one end is connected on the link pin, and the other end is connected on the slips body.
Be arranged with chute on described two semicircle conical surfaces, described slips body rear portion is arranged in the chute.
Be provided with into and out of gas circuit in described two slip spiders and be connected to console by the inlet, outlet pipeline connector.
Described a plurality of slips body is symmetricly set in two conical surfaces on the slip spider.
The utility model is simple in structure, prolong the drilling rod life-span, increase work efficiency, reduce labour intensity, utilize up, the descending drive appending disk motion of cylinder, thereby utilize the linkage component on the appending disk, it is up, descending along the conical surface to order about the slips body, little to drill rod abrasion, save production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is slip spider among the figure, the 2nd, and appending disk, the 3rd, the slips body, the 4th, cylinder, the 5th, guide peg, the 6th, contiguous block, the 7th, connect bearing pin, the 8th, connecting rod, the 9th, link pin, the 10th, link pin fixed block.
The specific embodiment
A kind of air spider, described chuck is by the slip spider 1 of two symmetries and the semicircle appending disk 2 of two symmetries, and a plurality of slips bodies 3, cylinder 4, guide peg 5 and linkage component constitute, be respectively equipped with the semicircle conical surface of symmetry on described two slip spiders 1, described cylinder 4 and guide peg 5 are connected between slip spider 1 and the appending disk 2 by nut respectively, described slips body 3 is connected with appending disk 2 by linkage component, described slips body 3 rear portions are arranged in the semicircle conical surface on the slip spider 1, described slips body 3 front portions are provided with the conical surface, the slip spider 1 of described two symmetries removably connects, two slip spiders 1 are provided with the slot of putting into for contiguous block 6, described two slip spiders 1 are provided with connection bearing pin 7 and fixedly connected with contiguous block 6 two ends respectively, described linkage component comprises connecting rod 8, link pin 9 and link pin fixed block 10, described link pin 9 is fixedly connected on the appending disk 2 by link pin fixed block 10, described connecting rod 8 one ends are connected on the link pin 9, the other end is connected on the slips body 3, be arranged with chute on described two semicircle conical surfaces, described slips body 3 rear portions are arranged in the chute, be provided with in described two slip spiders 1, go out gas circuit by advancing, go out gas path joint and be connected to console, described a plurality of slips bodies 3 are symmetricly set in two conical surfaces on the slip spider 1.
The utility model is installed in use and replaces the big quadrel of rotating disk in the big quadrel of the rotating disk hole, and the air spider upper end exceeds turntable surface slightly, and control system links to each other with the driller, by the unified control of driller station and operation.
During work, a plurality of slips bodies 3 are descending along the conical surface of slip spider 1 respectively, promoting drilling rod draws in to the center, when slips body 3 descending putting in place, transfer drilling rod, drilling rod cone step and the slips body 3 anterior conical surfaces are fitted, and the reliable support of drilling rod this moment can be opened elevator and carry out the unloading button and operated on slips body 3; Otherwise a plurality of slips bodies 3 can outwards open when up along the conical surface of slip spider 1 respectively, abdicate passage simultaneously, and drill string freely passes through from chuck hub.
