Detailed description of the invention
Fig. 1 is the anti-overall structure and application schematic diagram for putting off device of the utility model drilling well.
Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1
Referring to Fig. 1, the utility model drilling well is anti-to put off device, including controller 6 and combined aural and visual alarm 9, the acousto-optic
Alarm is connected with the output end of controller, and drilling well prevents that putting off device includes ram preventer fluid control pressure sensor 1 and flashboard
Preventer switch state detection switch/sensor 3, the ram preventer fluid control pressure sensor 1 are installed on ram preventer
Liquid lock pressure circuit on, the ram preventer switch state detection switch/sensor 3 correspondence is mounted on ram preventer 7
Check lock lever on；The output signal of the ram preventer fluid control pressure sensor passes through AD conversion module access controller 6, lock
Plate preventer switch state detection switch/sensor 3 output signal also accesses the controller 6.
The utility model drilling well is anti-to put off device, detects liquid using ram preventer fluid control pressure sensor 1 and locks pressure, adopts

State is accurately detected, and warns abnormal condition by combined aural and visual alarm, to ensure drilling well production safety.
Embodiment 2
Referring to Fig. 1, the drilling well of the present embodiment is anti-to put off device, difference from example 1 is that: it is interlocked including tourist bus
Control mechanism, tourist bus interlocked control mechanism include shuttle valve 4 and atmospheric control, and the shuttle valve 4 is connected in series in winch
In brake signal gas circuit 10, the delivery outlet of the shuttle valve 4 is connect with the downstream line of brake signal gas circuit 10, the shuttle valve 4
One input port is connect with the upstream line of brake signal gas circuit 10, another input port connects the gas circuit output of solenoid valve 5, institute
The gas circuit input terminal connection gas source of solenoid valve is stated, the solenoid valve controlled connection is in controller 6.
The controller 6 uses programmable controller or single-chip microcontroller, and the controller is connect with 8 interactive correspondence of industrial personal computer.
As shown in Figure 1, a threeway 2 is installed on the liquid lock pressure circuit of ram preventer, in the bypass of the threeway
Pressure sensor 1 is installed, ram preventer switch state detection switch/sensor 3 is installed on the check lock lever of ram preventer,
A shuttle valve 4 is sealed in the original brake signal gas circuit 10 of winch.Solenoid valve uses two-bit triplet normally closed solenoid valve, shuttle valve 4
An input port connect with the output port of two-bit triplet normally closed solenoid valve, the input port of two-bit triplet normally closed solenoid valve with
Gas source connection.The accordingly control that the control route of two-bit triplet normally closed solenoid valve and combined aural and visual alarm 9 is separately connected controller is defeated
Outlet.
Working principle: when ram preventer is closed, the pressure sensing installed in the threeway 2 of pressure circuit connection is locked with liquid
Device 1 collects liquid lock pressure value and is transferred to AD conversion module, the ram preventer being mounted on the check lock lever of ram preventer
Switch state detection switch/sensor 3 can sense that check lock lever stretches out, and controller real-time monitoring liquid lock pressure value and check lock lever are stretched
Ram preventer switch state detection switch/sensor issues after out switching signal is simultaneously transferred to integrated industrial personal computer 8, one
Change 8 one side of industrial personal computer and hydraulic pressure value and switching signal are shown to operator, on the other hand according to the pressure value of setting and switch
Signal, which issues instruction, opens two-bit triplet normally closed solenoid valve 5, and control gas enters the brake signal gas circuit of winch by shuttle valve 4
10, keep tourist bus movable to lock winch, while combined aural and visual alarm 9 being made to issue sound and light alarm signal.Work as ram preventer
When opening again after closing, liquid lock pressure value can be less than setting value under normal circumstances and check lock lever retracts, and ram preventer is opened
Off status detection switch/sensor switching signal disappears, and integrated industrial personal computer 8, which issues instruction, at this time makes the normally closed electricity of two-bit triplet
Magnet valve 5 restores normally off, and the winch of locking is unlocked and closes combined aural and visual alarm 9；It is lost if ram preventer liquid locks pressure
Often or check lock lever retraction is not in place, any one abnormal conditions occurs in the two, and winch can continue to lock, combined aural and visual alarm 9
Continue to issue sound-light alarm.
