Description
Technical field:
The utility model relates to safety monitoring equipment in a kind of oil drilling construction operation, particularly relates to the safety guard that transfinites in a kind of oilfield downhole operation construction.
Background technology:
In the oilfield downhole operation construction, the principal element that influences operating personnel and Work machine safety includes several respects such as the derrick load of Work machine, hook heave amplitude.In the oilfield downhole operation process, in case load and increasing degree transfinite, gently then have an accident, damage equipment heavy then fatal crass.Be the variation that changes observation down-hole equipment load by the reading of eye-observation tensiometer at present in the drillng operation; because the time is short; people's reaction is slow, so break drilling tool to what the unexpected increase owing to the drilling tool load caused, damage equipment, the generation protective effect of smashing accidents such as well head are little.Under the situations such as staff's overtired or energy is concentrated, the operation that often makes a mistake causes accident to take place.
Summary of the invention:
At the problems referred to above, the purpose of this utility model provides a kind of work machine load and increasing degree of can preventing to transfinite, and avoids the device of device damage and casualties.
The technical scheme that the utility model provides is:
The integration of operation car protective device that transfinites comprises pulling force sensor, displacement transducer, amplifying circuit, control instrument, Pneumatic valve, displacement high limit alarm and the high limit of dynamometry alarm, and the output of pulling force sensor connects control instrument by amplifying circuit; The output of displacement transducer connects control instrument by amplifying circuit; The output of control instrument connects the high limit of dynamometry alarm device, displacement high limit alarm and Pneumatic valve.
Control instrument is the singlechip CPU control circuit, and is provided with the guidance panel button.
The singlechip CPU control circuit is provided with pulling force, displacement digital display.
The signal of pulling force sensor and displacement transducer collection is transferred to control instrument through amplifying circuit.Control instrument calculates the signal that collects, and compares with the good numerical value of corresponding setting, according to the comparison result output signal to dynamometry, displacement high limit alarm and Pneumatic valve.If the high limit of dynamometry alarm equipment alarm illustrates that pulling force is excessive, need to adjust pulling force.If the high limit of displacement alarm equipment alarm illustrates that increasing degree is too high, need to reduce hoisting depth.Pneumatic valve can be realized interlock protection in the shortest time simultaneously, avoids accident to take place.
The utility model mainly is that high accuracy dynamometry and displacement sensing technology are applied on the underground work construction equipment, can realize that the underground work hook load controls automatically, travelling block upper and lower displacement automatic spacing, have automatic warning and interlock simultaneously, original machinery and fluid pressure type tensiometer can be replaced, automatic control load and travelling block upper and lower displacement automatic spacing can be realized.
The utility model can effectively be avoided breaking drilling tool, drawing the generation of turning over derrick, smashing well head and personal injury accident, and safety in production is had important effect.The utility model has solved a difficult problem that perplexs the driver operation personnel for a long time simultaneously, avoid the driver because of not seeing tensiometer video data and travelling block position, or because of energy maloperation takes place in unconcentrated, overtired or down-hole emergency case etc., can effectively prevent the generation of accident, bring remarkable economic efficiency.

Specific embodiment
The integration of operation car protective device that transfinites comprises pulling force sensor, displacement transducer, amplifying circuit, control instrument, Pneumatic valve, displacement high limit alarm and the high limit of dynamometry alarm, and the output of pulling force sensor connects control instrument by amplifying circuit; The output of displacement transducer connects control instrument by amplifying circuit; The output of control instrument connects the high limit of dynamometry alarm device, displacement high limit alarm and Pneumatic valve.Control instrument is the singlechip CPU control circuit, and is provided with the guidance panel button.The singlechip CPU control circuit is provided with pulling force, displacement digital display.
Characteristic of property of the present utility model
1, can realize automatic control load, travelling block upper and lower displacement volitional check. Can effectively avoid breaking drilling tool, draw and turn over well Frame smashes the generation of aboveground and personal injury accident, can stand stronger vibrations and frequently high-torque variable force impact, has Waterproof, grease proofing, the anti-soaking performance, volume is little, and is in light weight, highly sensitive, good stability, automaticity height, operation side Just, not fragile, it is convenient to observe, and has the function of warning and emergency brake when showing data.
2, the utility model is applied in the dynamometry technical sensor on the job execution equipment, load accurately can not only be shown, and is the heaviest What want is the data acquisition that can pass through down-hole equipment load and travelling block change in location, after micro computer is processed the data processing, Instruction is sent to warning device and interlock, thereby avoid the generation of accident and cause personal injury, realize safety in production. This is that traditional tensiometer can not be accomplished.
3, High Precision Strength Measurement Sensor and displacement transducer are installed on the working rig, in order to measure relevant data-signal, this letter Number be transferred to the data acquisition and processing (DAP) unit, finally make system finish record, display alarm and the brake of data-signal. This system Not only absorb the advantage of the hydraulic tensometer of every day use, and the LCD Panel with backlight function can be directly installed on In face of the driver control console, solved the driver and observe inconvenient problem in night and overcast and rainy construction, the driver can directly pass through Display is observed the pulling force data variation of down-hole equipment and the variation of travelling block position, and pulling force sensor and displacement biography Sensor can be set service load and work shift amount as required, surpasses load and the position that arranges when actual pulling force or actual displacement When moving, micro processor can in time send alarm signal, reminds the driver, and the work order of will brake in time is transferred to interlock and stops On the mechanism of car, avoid the generation of accident.
