Abstract
The invention relates to a pneumatic chuck which is formed by two symmetrical slips bases, two symmetrical semi-cylindrical suspending plates, a plurality of slips bodies, an air cylinder, a guiding rod and a connection rod part. The two slips bases are respectively provided symmetrical semi-circular conical surfaces, the air cylinder and the guiding rod are respectively connected between the slips bases and the suspending plates through nuts, the slips bodies are connected with the suspending plates through the connection rod part, the rear portions of the slips bodies are arranged in the semi-circular conical surfaces on the slips bases, and conical surfaces are arranged on the front portions of the slips bodies. The pneumatic chuck is simple in structure, prolongs the service life of the drill rod, improves working efficiency, reduces labor intensity, drives the suspending plates to move through upward and downward moving of the air cylinder, accordingly drives the slips bodies to move upwards and downwards along the conical surfaces through the connection rod part on the suspending plates, is small in abrasion on the drill rod and saves production cost.
Description
Technical field
The present invention relates 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 drilling floor surface, then the button operation of screwing on.In job site in the past, use be the various air operated slips that patent discloses, although structure is slightly variant, but principle is all the same, is all the power that provides by cylinder, produces radial clamping power, by the larger screw die of hardness, roofbolt is clamped, the extruding that screw die and roofbolt produce is inevitably squeezed drilling rod bad chewing, 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 patent of invention ZL 200920037277.6 " a kind of drilling rod " is born, by improving, design a kind of simple in structurely, safe and reliable chuck is that realistic meaning is arranged very much.
Summary of the invention
The present invention for overcome the above problems provide a kind of simple in structure, extend Life of drill rod, increase work efficiency, reduce the air spider of labour intensity.
Technical scheme of the present invention 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 symmetrical semicircle conical surface on described two slip spiders, described cylinder and guide peg are connected between slip spider and 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 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 and connect bearing pin and be fixedly connected with 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 appending disk by the link pin fixed block, and described connecting rod one end is connected on 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 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 slip spider.
The present invention is simple in structure, extend Life of drill rod, increase work efficiency, reduce labour intensity, utilize up, the descending drive appending disk motion of cylinder, thereby utilize the linkage component on appending disk, order about the slips body up, descending along the conical surface, little to drill rod abrasion, save production cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure, 1 is slip spider, 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 consist of, be respectively equipped with the symmetrical semicircle conical surface on described two slip spiders 1, described cylinder 4 and guide peg 5 are connected between slip spider 1 and 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 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 and connect bearing pin 7 and be 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 appending disk 2 by link pin fixed block 10, described connecting rod 8 one ends are connected on link pin 9, the other end is connected on slips body 3, be arranged with chute on described two semicircle conical surfaces, described slips body 3 rear portions are arranged in chute, be provided with in described two slip spiders 1 into, go out gas circuit by advancing, go out gas path joint and be connected to console, described a plurality of slips body 3 is symmetricly set in two conical surfaces on slip spider 1.
The present invention is arranged in use and replaces the large quadrel of rotating disk in the large quadrel of rotating disk hole, and the air spider upper end exceeds turntable surface slightly, and control system is connected with the driller, controls and operates by driller station is unified.
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 is descending when putting in place, transfer drilling rod, the anterior conical surface of drilling rod cone step and slips body 3 is 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, can outwards open when a plurality of slips bodies 3 are up along the conical surface of slip spider 1 respectively, abdicate simultaneously passage, drill string freely passes through from chuck hub.
