Description
Technical field
This utility model relates to the automatically controlled anti-lifting safety device in oil field.
Background technology
Hydraulic blow out preventer is widely used in petroleum exploration and development drilling well very important to prevent blowout equipment.Existing half envelope flashboard hydraulic blow out preventer carries out opening, cutting out by control system of preventer.When half envelope flashboard hydraulic blow out preventer is in opening, can make a trip；And when semiclosed plate hydraulic pressure open flow device is closed, owing to drilling tool is blocked by preventer, then can not make a trip.Existing brake cylinder by rig colliding crown block gas circuit gentle stop gas circuit control, touch off when colliding crown block or stop with gas gas circuit brake time, rig cylinder can be stopped extremely by brake cylinder.And when half envelope flashboard hydraulic pressure open flow device cuts out, brake cylinder is still in free state.Due to the limitation in equipment design itself, and anthropic factor during use, cause after preventer cuts out it may happen that propose brill maloperation and damage preventer, sleeve pipe or drilling tool etc..
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of simple in construction, can be prevented effectively from the automatically controlled anti-lifting safety device that accidents such as drawing bad ram block because carrying drilling rod after barring up preventer occurs.
For achieving the above object, this utility model adopts the following technical scheme that
Automatically controlled anti-lifting safety device, including for controlling reversal valve that preventer is turned on and off, power supply, proximity switch, relay, guard grating, the first appendix, the second appendix, the 3rd appendix, source of the gas, electromagnetic valve, brake cylinder assembly, three-way shuttle valve, brake cylinder, brake lever；Described power supply, electromagnetic valve and guard grating are all connected with relay, and described proximity switch is connected with guard grating；This proximity switch is fixed on reversal valve, for detecting the open and-shut mode of reversal valve, and sends status signal to relay by guard grating；Described source of the gas is connected with electromagnetic valve by the first appendix, and electromagnetic valve is connected with brake cylinder assembly by the second appendix, and described brake cylinder assembly connects brake cylinder by the 3rd appendix, and described brake lever is connected with brake cylinder.
Preferably, also including that display lamp, described display lamp are connected with relay, power supply is that display lamp is powered.
Preferably, also include that explosion-proof tank, described power supply, relay, guard grating are mounted in explosion-proof tank.
Preferably, also include that explosion-proof button, described explosion-proof button are connected with relay.
Compared to existing technology, the beneficial effects of the utility model are:
This utility model is by detecting the open and-shut mode of the reversal valve of preventer, when reversal valve cuts out, control source of the gas by signal transmission and transmit to brake cylinder, make brake cylinder pressure brake lever prevent from carrying brill, it is thus possible to avoid having an accident, after reaching shut-in well, use the purpose of wellhead equipment safely.

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
See Fig. 1 and Fig. 2, this utility model provides a kind of automatically controlled anti-lifting safety device, it includes for controlling the reversal valve 1 that preventer is turned on and off, and also includes power supply 2, proximity switch 3, relay 4, guard grating the 5, first appendix the 6, second appendix the 7, the 3rd appendix 8, source of the gas 9, electromagnetic valve 10, brake cylinder assembly 11, three-way shuttle valve 12, brake cylinder 13 and brake lever；Wherein, power supply 2, electromagnetic valve 10 and guard grating 5 are all connected with relay 4, and described proximity switch 3 is connected with guard grating 5；This proximity switch 3 is fixed on reversal valve 1, for detecting the open and-shut mode of reversal valve 1, and sends status signal to relay 4 by guard grating 5；Described source of the gas 9 is connected with electromagnetic valve 10 by the first appendix 6, electromagnetic valve 10 is connected with brake cylinder assembly 11 by the second appendix 7, described brake cylinder assembly 11 connects brake cylinder 13 by the 3rd appendix 8, and brake lever (not shown) is connected with brake cylinder 13.
As preferably, also including explosion-proof button 14, this explosion-proof button 14 is connected with relay 4.
Operation principle is:
Proximity switch 3 is arranged on the reversal valve 1 of preventer, is used for sensing reversal valve 1 position of the switch；When reversal valve 1 is in off-position, when i.e. preventer cuts out, proximity switch 3 sends signal and is amplified by guard grating 5 signal and transmitted to relay 4, relay 4 controls electromagnetic valve 10 and opens to connect source of the gas 9 afterwards, source of the gas 9 is circulated to brake cylinder assembly 11 by the first appendix 6, electromagnetic valve the 10, second appendix 7, source of the gas 9 is circulated to brake cylinder 13 by the 3rd appendix 8 afterwards, makes brake cylinder 13 move downward, and pressure brake lever prevents from carrying brill；And when reversal valve 1 is in open position, namely preventer is opened, proximity switch 3 sends after signal is amplified by guard grating 5 and exports to relay 4, relay 4 controls electromagnetic valve 10 and cuts out, thus source of the gas 9 cannot i.e. interrupt source of the gas 9 by the second appendix 7, recovers to put forward brill function；When needing suitably to carry brill after ram block is closed, explosion-proof button 14 can be pressed and recover to put forward brill function.
As preferably, this utility model can also increase the setting of display lamp 15, and this display lamp 15 is connected with relay 4, power supply 2 is powered for display lamp 15, when proximity switch 3 detects that reversal valve 1 is closed, it is shinny that relay 4 controls display lamp 15, to remind staff.
Also include that explosion-proof tank 16, power supply 2, relay 4, guard grating 5 are mounted in explosion-proof tank 16.Owing to working environment has combustible dust, fuel gas etc., by explosion-proof tank 16 these environmental areas of electrical equipment principle, it is provided that a comparatively safe working environment.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to this utility model scope of the claims.
