Problems solved by technology

However, in actual operation, due to the influence of human factors, mistakes often occur, resulting in the situation that the travel car hits the drill floor (commonly known as the sudden drill) when it goes down and speeds up.
Especially when the drilling tool is lowered quickly with a large suspension weight, if the traveling car loses control, it will cause serious accidents, often causing personal injury or even machine crash

Embodiment 1

[0028] see figure 1 , the oil drilling engineering drilling rig / traveling block anti-out-of-control control method of the present invention, in the existing drilling rig / traveling block control circuit, an adjustable automatic control template (by signal acquisition) is inserted between the driller's switch and the silicon controlled rectifier device unit, processing unit and thyristor voltage regulating unit) to realize the safety control of drilling rig / cruise intervention:

[0029] 1) The signal acquisition unit collects the low-voltage AC signal output by the driller's switch in real time, and transmits it to the processing unit after rectification and step-down processing. The processing unit detects and analyzes the voltage signal after rectification and step-down processing in real time, and controls the controllable signal according to the instructions of the PLC. The silicon voltage regulating unit modulates and outputs a 0-20V AC voltage signal to the thyristor recti...

Embodiment 2

[0032] In oil drilling engineering, when drilling, the driller must operate the driller's switch to activate the electromagnetic eddy current brake to slow down the traveling car at different positions, so as to prevent the traveling car from overspeeding or out of control; the oil drilling rig / cruising car in this embodiment The anti-runaway control method is different from Embodiment 1 in that further, according to this characteristic, the travel distance of the traveling train is divided into N intervals from top to bottom, N is a natural number greater than or equal to 1, and each interval is set There are traveling car height value H, speed value S and matching voltage signal value V;

[0033] PLC real-time detection and analysis of the traveling vehicle height value h, speed value s and voltage signal value v, and real-time comparison with the traveling vehicle height value H, speed value S and voltage signal value V of each interval set;

[0034] 1) If the traveling block...

Embodiment 3

[0038] see Figure 4 , the oil drilling engineering rig / traveling vehicle anti-out-of-control control method of the present embodiment is different from Embodiment 2 in that: when the traveling vehicle is in an out-of-control state, the PLC starts the electromagnetic eddy current brake to slow down the traveling vehicle, and also activates the disc brake interlocking device Send an instruction to make the two-position five-way solenoid valve in the device work immediately, cut off the normally open air circuit A connecting the main clutch and high and low speeds, and open the normally closed air circuit B to supply air to the pneumatic disc brake to achieve the purpose of braking .

Abstract

The invention discloses a control method and system for preventing out-of-control of an oil drilling engineering drilling rig / traveling block. An automatic control template with the pressure capable of being adjusted is inserted between a drilling rig / traveling block control driller switch and a thyristor rectifier, a low-voltage alternating current signal output by the driller switch is collectedin real time, and transmitted to a processing unit after rectifying and reducing the voltage, the processing unit detects and analyzes in real time and controls a thyristor voltage regulating unit tomodulate and output an alternating current voltage signal of 0-20 V to the thyristor rectifier according to an instruction of a PLC; the changes of the height and the speed of thedrilling rig / traveling block are captured in real time by using a winch sensor / hook position sensor, height and speed values of the traveling block are detected and analyzed in real time by using the PLC, and transmittedto the processing unit. The downward speed of the traveling block is monitored by using the winch sensor, a given voltage signal output by the driller switch is used for judging whether the travelingblock is within the controllable range or not, then through the automatic control template and an electromagnetic eddy current brake system, the drilling rig / traveling block is prevented from losingcontrol due to improper operation or accident, and the economical effect, safety and reliability are achieved.

Description

technical field [0001] The invention relates to oil drilling engineering safety control technology, in particular to an oil drilling rig and traveling car automatic brake control safety protection device and an oil drilling rig and traveling car automatic braking safety protection system. Background technique [0002] In the process of oil exploration, development and drilling, preventing the stall of the drilling rig and traveling vehicle is the essential requirement of safe production. At present, in the process of domestic drilling operations, a drilling machine is equipped with two sets of brake systems, one is a friction-type main brake system that relies on the action of brake discs and brake blocks, which includes two types of working tongs and safety tongs. The main brake system plays an important role in tripping, feeding, parking and emergency braking in drilling operations. The other is a non-friction auxiliary braking system that relies on electromagnetic eddy c...
