Description
Technical field
The invention belongs to oil drilling and extracting equipment field, and in particular to a kind of oil drilling removes the automation clamping machine of drilling rod
Structure.
Background technology
Oil is the extremely important industrial energy in the world today, in recent years, with continuing to develop for oil drilling industry, stone
Oily exploitation field proposes higher and higher technical requirements for oil equipment.Tube apparatus is removed, oil pipe mobile device is oil field
Interior capital equipment, and oil pipe clamping mechanism is one of common main part of above equipment, therefore oil pipe clamping machine
Structure improves and innovation has more important practical significance.The clamping device that current iron driller is used has following defect：1st, different mouths
The oil well in footpath needs various sizes of oil pipe, thus needs frequently change grip block at work and clamping device is more multiple
Miscellaneous, the loading and unloading of grip block is also comparatively laborious, it is impossible to meet change in oil pipe in the range of certain size job requirement 2,
The grip block of some oil pipe clamping mechanisms skewness around oil pipe causes oil-pipe external wall concentrated wear.3rd, current well head is normal
It is low with the automatic and mechanical degree of elevator, the manually operated of workman is fully relied on, the working strength of workman is big, work limitation
It is low, and there is potential safety hazard during oil pipe handling.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of new iron driller caliper clamping slips.
The technical scheme is that：
A kind of new iron driller caliper clamping slips, including oil cylinder hinged seat 1, slips connecting plate 2, slip spider 3, slips body
5th, telescopic oil cylinder 6, steel spring plate 10.Wherein, slips body 5 is bolted in the inside groove of slip spider 3, and in centre bit
Put；Two telescopic oil cylinders 6 are arranged on the both sides of slips body 5, are axisymmetricly distributed, both sides telescopic oil cylinder 6 is fixed on card by bearing pin
In watt inside groove of seat 3；Piston rod one end of telescopic oil cylinder 6 is moved freely in hydraulic cylinder, one end of the other end and oil cylinder hinged seat 1
Connected by bearing pin, the other end of oil cylinder hinged seat 1 is fixed by bearing pin with slips connecting plate 2, passes through telescopic oil cylinder piston rod
It is displaced outwardly, drives both sides slips connecting plate 2 to gather to inner side, reaches the effect of automation clamping.
Described slips body 5 includes clamping the first chain link 7 of dental lamina 4, slips, middle shot 9, slips tail chain section 11；Described
One end of slips head chain links 7 is fixedly connected by bearing pin with side slips connecting plate 2, the other end and the middle shot 9 of first chain link 7
One end be hinged by bearing pin and sliding bearing 8；The other end of middle shot 9 passes through bearing pin and sliding bearing 8 and slips tail chain
One end of section 11 is hinged, and the other end of slips tail chain section 11 is fixedly connected by bearing pin with the slips connecting plate 2 of opposite side；Work as iron
When driller is in clamp position, the piston rod of both sides telescopic oil cylinder 6 stretches out, and drives slips connecting plate 2 to move, and then make internal slips
Body 5 is inwardly gathered, and reaches the effect for clamping oil pipe.Described clamping dental lamina 4 is bolted on slips chain link inner surface, when
When chain link is gathered, slip dog 4 is moved with chain link, when clamping dental lamina 4 touches oil pipe outer surface, is adsorbed in outer wall simultaneously
And conventional dentation pincers tooth can be avoided directly to bite oil-pipe external wall, stress raisers are caused to the damage at oil connection.Institute
Two steel spring plates 10 stated are located at the outside of slips chain link, and the two ends of steel spring plate 10 are connected by bolt with adjustment cover plate 12
Connect, adjustment cover plate 12 is fixed on the slips backplate 2 of both sides, by applying outside to chain link through chain link projection
Power, the uncertain rotation for limiting link ensures that clamping device remains class round shape, facilitates oil pipe to clamp.
Beneficial effects of the present invention:1. clamp force distribution suffered by tubing wall is uniformly prevented oil pipe using chain gripper mechanism
Outer wall concentrated wear；2. oil cylinder is flexible to realize that gear grips can obtain reliable clamping force and easily realize clamping automation
Control, is easy to be applied in various automatic oil pipe chucking devices；3. two latch plates apply through chain link projection to chain link
The uncertain rotation that outside tension force can limit link makes clamping device remain class round shape, facilitates oil pipe to clamp；4. chain
The design of section projection increases chain link with the contact area of its support base to improve the reliability of clamping device；5. chain internode
Using bearing pin and distal opening pin connection, facilitate dismounting and change, and can be by increasing or decreasing chain link number and selecting suitable
When the oil cylinder of stroke to adapt to the oil pipe of different dimensions.
Brief description of the drawings
Fig. 1 is the schematic diagram that new iron driller oil pipe clip holds watt；
Fig. 2 is that new iron driller oil pipe clip holds a watt interior three-dimensional figure；
In figure：1 oil cylinder hinged seat；2 slips connecting plates；3 slip spiders；4 clamp dental lamina；5 slips bodies；6 telescopic oil cylinders；7 cards
Watt first chain link；8 connection rolling bearings；9 middle shots；10 steel spring plates；11 slips tail chain sections；12 adjustment cover plates.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
