Abstract
The utility model discloses a safety controller for the drilling winch used in the petroleum industry, and the utility model is used in various drilling winches. The safety controller for the drilling winch controls the descending speed of the driller traveling system, and the safety controller for the drilling winch avoids or reduces the generation of the equipment and the personnel safety accident. The device is made up by a signal acquisition sensor, a data processing unit and a control unit. The components are connected by signal transmission lines. The signal acquisition sensor is installed on the drive shaft of the winch barrel. The control unit is connected with the air cylinder of the driller brake system through the pipe lines of the air control or the liquid control. The utility model can effectively control the descending speed of the winch. When the driller traveling system descends, and after the distance is three meters apart from a rotary tray surface, and when the speed is overquick, the utility model is regulated to the safe range settled automatically. The protecting functions for the drilling personnel, the drilling equipment, the drilling tool below the well and the well bore are performed. The safety controller for the drilling winch avoids or reduces the generation of the equipment and the personnel safety accident.
Description
Technical field
The utility model relates to the drilling equipment of oil drilling industry, particularly drilling well winch safety control is suitable for various drilling well winches and uses, and controls its lowering velocity automatically, thereby the downstream rate of control rig traveling system is avoided or the generation of minimizing equipment and personal safety accident.
Technical background
Using in the drilling equipment of petroleum industry situ of drilling well, the drilling well winch is one of most important equipment, and the traveling system of rig is controlled by the drilling well winch.Often run into drilling well winch operator causes rig because of maloperation traveling system at the scene and pound accident to turntable surface with fast speed, the drilling well industry is commonly called as the percussion drill accident.The lighter causes device damage, the drilling tool well that falls, and weight person can cause personnel's injures and deaths.At present, the method for avoiding this problem is to carry out personnel's training, strengthens operator's sense of responsibility, but the device that drilling equipment itself does not prevent and avoids this type of accident to take place.
Summary of the invention
The purpose of this utility model provides drilling well winch safety control, fills up the technological deficiency that the supporting aspect of existing drilling equipment safety exists.Under the situation of operating personnel's maloperation or misoperation, this safety device is worked automatically, avoids the generation of percussion drill accident, guarantees safe, protection drilling equipment that drilling well is produced.
The present technique solution can reach above-mentioned purpose: drilling well winch safety control is made up of signals collecting sensor, data processing unit and control module, with signal transmssion line above-mentioned parts are connected, the signals collecting sensor is installed on the power transmission shaft of winch drum, control module is communicated with the cylinder or the hydraulic cylinder of borer brake system by gas control or hydraulic control pipeline.
After using the utility model, the lowering velocity of winch is effectively controlled, and has filled up the defective that existing drilling well winch does not have safety control.When 3 meters later lowering velocities of line-spacing turntable surface are too fast under the rig traveling system,, make it to remain in the safe range of setting by this device auto-control.Play protection to drilling implementer, drilling equipment, down-hole equipment and well.Avoid or the generation of minimizing equipment and personal safety accident.
Description of drawings
Accompanying drawing is a connection schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, drilling well winch safety control is made up of signals collecting sensor 1, data processing unit 2 and control module 3, with signal transmssion line above-mentioned parts is connected.Signals collecting sensor 1 is installed on the power transmission shaft of winch drum, gathers the rotating speed and the traveling system location parameter of winch drum, transfer to data processing unit 2 in the mode of the signal of telecommunication.The data that data processing unit 2 is gathered signals collecting sensor 1 are converted to the speed parameter and the location parameter of rig traveling system, and these data compare in order to the speed parameter with data processing unit 2 settings.When traveling system in setting height, when its lowering velocity exceeded setting range, data processing unit 2 sent signal and gives control module 3.Control module 3 is communicated with the cylinder or the hydraulic cylinder of borer brake system 4 by gas control or hydraulic control pipeline, when the instruction that receives data processing unit 2, at once by borer brake system 4 brake decelerations.Control module 3 is made up of electromagnetic valve, signal cable interface, power cable interface and pipe interface, and the signal cable interface is connected with data processing unit 2, and the power cable interface is connected with electromagnetic valve, and pipe interface is connected with gas control or hydraulic control pipeline.When used borer brake system 4 was hydraulic control, control module 3 is installed by 2 electromagnetic valves and 2 fluid pressure lines are communicated with the hydraulic cylinder of borer brake system 4.The action of control module 3 regulation and control electromagnetic valves, thus brake operation is carried out in 4 actions of control borer brake system, makes the speed of traveling system descending in setting range.When traveling system speed reaches in the setting range, remove brake by signals collecting sensor 1, data processing unit 2, control module 3 and electromagnetic valve and borer brake system 4 again.When traveling system speed surpasses setting value once more, repeat above process,, in setting range, avoid with this downstream rate of controlling traveling system because the too fast accident that causes of rig traveling system downstream rate.This device is two independently parallel systems with the brake gear of drilling well winch, even this device is not worked, does not also influence the normal running of drilling well winch.The utility model has been installed, has not also been influenced any structure and the performance of drilling well winch, only winch has been played the security control effect.
