Detailed description of the invention
Below we by reference to the accompanying drawings and particularly embodiment shackle device on the well head on the utility model oil-well rig done further elaborate; understand its structure composition and working method in the hope of more cheer and bright, but protection domain of the present utility model can not be limited with this.
As shown in Figure 1, the utility model is shackle device on well head on a kind of oil-well rig.On this well head, shackle device includes Hydraulic Station 1, electromagnetic valve 2, hydraulic catwork 3, wire rope 4, Type B hydraulic tongs 5 and pulling force sensor 6 and pressure transmitter.Described hydraulic catwork 3 is two, two hydraulic catworks 3 are communicated on Hydraulic Station 1 respectively by hydraulic hose 7, hydraulic hose 7 is provided with electromagnetic valve 2, and this electromagnetic valve 2 is electromagnetic hydraulic pressure switching valve, can by the action turning to folding and then hydraulic control cat head 3 of Controlling solenoid valve 2.Be provided with pressure transmitter in pulling force sensor 6, pulling force signal is become hydraulic pressure signal by pulling force sensor 6, is connected with pressure transmitter by hydraulic hose, and hydraulic pressure signal is become current signal by pressure transmitter, for controller collection.
Two hydraulic catworks 3 are connected on two Type B hydraulic tongs 5 respectively by wire rope 4, two Type B hydraulic tongs 5 are stuck on upper and lower two drilling rods of needs installation or removal respectively, the wire rope 4 being stuck in the Type B hydraulic tongs 5 of top rod is provided with described pulling force sensor 6, this pulling force sensor 6 is communicatively coupled to a controller 8, this controller 8 is connected on an interactive operation equipment 9, and this interactive control equipment 9 connects described electromagnetic valve 2.Above-mentioned interactive control equipment 9 is a touch-screen.
Be that two, left and right hydraulic catwork 3 connects two Type B hydraulic tongs, 5, two Type B hydraulic tongs 5 respectively by wire rope 4 and vises two drilling rods needing shackle respectively in upper shackle process.A drilling rod fixed below in two Type B hydraulic tongs 5, ensure rotation in below drilling rod do not follow above drilling rod rotate, the screw thread of such two drilling rods can be separated or revolve closely.
As shown in Figure 2, above the touch-screen of in return control appliance 9, be provided with multiple virtual key, be respectively button button, shackle button, start button and stop key.The operation of upper button and shackle operation is realized by the touch of button.
On well head on the utility model oil-well rig in shackle device, the predetermined torque value inputted by interactive control equipment 9 is provided with in described controller 8, what pulling force sensor 6 described in this inputed to controller 8 is real-time torque value, when real-time torque value is more than or equal to described predetermined torque value, the electromagnetic valve 2 described in described controller 8 output order stops.
Using on well head of the present utility model, in the process of shackle device, as shown in Figure 3 and Figure 4, operating personnel are by Controlling solenoid valve, and output hydraulic pressure power is to hydraulic catwork.Hydraulic catwork drives wire rope, and wire rope drives Type B hydraulic tongs to rotate centered by drilling rod.Operating personnel observe dial gauge always in this process, and in time reaching torque wrench moment, shut electromagnetic valve, completes button.Specifically, operating personnel, according to drilling rod designing requirement, first input predetermined torque wrench moment value, then detain function on selecting in the touch-screen of in return control appliance 9.Click and start, perform by controller 8 and detain operation.Controller 8, by the value of thrust of Real-time Collection pulling force sensor 6, completes a closed-loop control system, judges current upper buckle-like state or the state of shackle according to value of thrust.Auxiliary reclay is controlled by output point, and then Controlling solenoid valve 2, the power of Hydraulic Station 1 is input in hydraulic catwork 3.When reaching torque wrench moment, controller 8 is cutting-off liquid pressure power automatically, and work is detained in stopping.Whole process is all independently completed by controller 8, can detain work, ensure torque wrench moment, go up in button process simultaneously and can realize steady hydraulic control power, reduce the possibility of causing danger owing to pulsing on the very first time disconnects.
Compared to the operation of upper button, shackle operation is relatively simple, the value of thrust of controller 8 in real time in more current value of thrust and a upper process, in time occurring that current value of thrust is less than a upper process value of thrust, and stopping shackle work.When once going up shackle and not completing, controller 8 can enter next operating process automatically, waits for and goes up shackle work next time.Until meet upper shackle termination condition, complete shackle work.
The utility model is on the hydraulic catwork of routine in button instrument, adds auxiliary reclay, pressure transmitter and stube cable, instrumentation controller and touch-screen, and in increase, shackle control program and interactive controlling picture just can complete upper shackle work automatically.Explosion-proof pressure transmitter selected by pressure transmitter, and model is selected according to pressure control range.The auxiliary reclay increased, coordinates the output point of controller, controls solenoid operated directional valve, the Power output of indirect hydraulic control cat head.
