On oil-well rig of the present utility model tourist bus anti-on touch under pound in device, described laser range sensor connects safety barrier to form intrinsic safety loop by H cable, and laser distance sensor is as intrinsic safe explosion-proof laser range sensor.
On oil-well rig of the present utility model tourist bus anti-on touch under pound in device, be provided with the upper and lower bound threshold value of the hook height arranged by touch-screen in described controller, show the real-time height of hook on the touchscreen.
Compared with prior art, on the utility model oil-well rig tourist bus anti-on touch down the beneficial effect pounding device and be:
1, laser range sensor of the present utility model is swift in response, and can use under adverse circumstances at the scene, and precision of laser ranging is accurate, not by wind speed, light, temperature and noise effect.
2, laser range sensor of the present utility model and safety barrier together form intrinsic safety loop, can use in hazardous environment, thus add the safety of whole system.
3, have employed touch-screen in the utility model, simply arrange by touch-screen, intuitive display is convenient, friendly interface.
Accompanying drawing explanation
Fig. 1 be tourist bus on the utility model oil-well rig anti-on touch down the structure composition schematic diagram pounding device.
Fig. 2 be tourist bus on the utility model oil-well rig anti-on touch down the circuit connection diagram of pounding device.
Detailed description of the invention
Below we by reference to the accompanying drawings with specific embodiment to tourist bus on the utility model oil-well rig anti-on touch down and pound device and do and 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 Fig. 1 and Fig. 2, described oil-well rig includes overhead traveling crane 1, tourist bus 2 and drilling floor surface 3, described tourist bus 2 moves up and down between overhead traveling crane 1 and drilling floor surface 3, hook 4 is provided with in the bottom of tourist bus 2, described overhead traveling crane 1 is T with drilling floor surface 3 spacing, and the height of tourist bus 2 itself is L, and the distance between tourist bus 2 to overhead traveling crane 1 is variable X, then described hook 4 is also a variable apart from the height H of drilling floor surface 3, H=T-X-L.On the utility model oil-well rig tourist bus anti-on touch down and pound device and structurally mainly include laser range sensor 5, safety barrier 6, controller 7, brake relay 8, release-push 9 and touch-screen 10.
Wherein, described laser range sensor 5 utilizes support to be fixed on the lower end of overhead traveling crane 1, and the probe of this laser range sensor 5 is just to described tourist bus 2.Above-mentioned laser range sensor 5 needs power supply, and laser range sensor 5 is powered by driller house electric control box, and the two is connected by H cable.
Above-mentioned safety barrier 6 connects described laser instrument distance measuring sensor 5 with sensor-lodging, this safety barrier 6 connects the controller 7 that also transmission sensor signal is extremely described, an output of described controller 7 connects touch-screen 10, an output connects brake relay 8, and this brake relay 8 connects the start-stop that described release-push 9 brakes with control panel.
Laser ranging detection technique is the technology of current comparative maturity, it is applied to petroleum industry and is highly profitable by us, the environment such as wind speed, light, temperature and noise during the oil-well rig well-digging of field do not disturb completely to it, and laser ranging is swift in response, and is applicable to the operating mode of tourist bus high-speed cruising.
On the utility model oil-well rig tourist bus anti-on touch down that to pound the laser range sensor that device adopts be intrinsic safety type sensor, laser range sensor and safety barrier form essential safety loop (being called for short intrinsic safety loop), can ensure the safety of the on-the-spot person and equipment.Controller adopts SIEMENS PLC-200, can carry out programming and stable and reliable for performance, and the touch-screen of Siemens's brand can carry out the setting of upper and lower bound, and simple interface is directly perceived.Above-mentioned safety barrier receives the sensor signal of laser range sensor and exports to controller, and hook height shows by controller on the touchscreen.Hook height design formulas H=T-X-L is provided with in programmable controller.Laser range sensor sends laser pulse can detect the relative distance X of tourist bus to overhead traveling crane, if overhead traveling crane is T to drilling floor surface distance, tourist bus distance itself is L.The close node of brake relay and release knob and dish are stopped and are tightly stopped together with the string of loop, and touch-screen can arrange hook height bound, if hook height transfinites, then controller output switch amount signal is to brake relay action.Release-push be used for anti-on touch down pound system acting after separate lock collar brake.
The utility model is a kind of novel oil-well rig hunting upper-bumping lower-breaking preventing system, it can complete the measurement to hook height, and touch on tourist bus or under the deathtrap of pounding stopped by controller control relay pair twist hull and outputed signal the brake that pair twist hull stops, tourist bus bound can be set realize preventing of tourist bus touches down the effect of pounding, measure accurately, reliable in action, and use safety.
