Intelligent safety rope suspension device

Abstract

The invention provides an intelligent safety rope suspension device. The intelligent safety rope suspension device comprises a buffering box, a rope suspension machine body, an intelligent module, oil-resistant rubber, a square clamp, a baffle, a polished rod and at least one spare clamp. A first groove is formed in the bottom end in the buffering box, the baffle is arranged on the rope suspensionmachine body, the square clamp is arranged on the baffle, and the buffering box is arranged at the bottom of the rope suspension machine body. The oil-resistant rubber is arranged in the first grooveof the buffering box, the polished rod vertically penetrates through the square clamp, the baffle, the rope suspension machine body, the buffering box, the spare clamps and the oil-resistant rubber,and the polished rod, the square clamp and the spare clamps are fixedly connected. The spare clamps are arranged in the buffering box, and the distance between the bottom faces of the spare clamps andthe oil-resistant rubber is a collision height. The intelligent module is arranged in the buffering box. The intelligent module includes a collision switch and a signal sending control board, and thecollision switch and the signal sending control board are electrically connected. When the spare clamps collide with the collision switch, the collision switch is closed, and the signal sending control board is used for sending collision signals to a control cabinet when the collision switch is closed.

Description

technical field [0001] The invention relates to the technical field of oil production engineering, in particular to an intelligent safety rope suspension device. Background technique [0002] At present, the main surface oil production tool is the pumping unit. As the oilfield development enters the middle and later stages, the well fluid contains water, wax, and the viscosity of the well fluid increases year by year, resulting in a larger and larger difference in the suspension point load of the donkey head up and down strokes. The larger the impact vibration of the entire pole system, the greater it will be. The water content in the well fluid increases year by year, resulting in more and more eccentric wear of the rod and pipe, causing additional bending moments at the polished rod, and causing the polished rod to break under the action of alternating loads, resulting in serious safety and environmental protection accidents. After the polished rod is broken, it is easy t...

AI Technical Summary

Problems solved by technology

The water content in the well fluid is increasing year by year, which leads to more and more serious eccentric wear of the rod and tube, causing additional bending moments at the polished rod, and causing the polished rod to break under the action of alternating loads, leading to serious safety and environmental protection accidents

After the polished rod is broken, it is easy to cause the following serious consequences: more than ten tons of the rod collide with the anti-blowout box, causing oil leakage, which requires work; when the donkey head of the pumping unit has no load during the upstroke, it is easy to cause motor burnout and various serious safety accidents
