Intelligent deep hole rope winch driven by variable frequency motor

Abstract

The invention discloses an intelligent deep hole rope winch driven by a variable frequency motor. The intelligent deep hole rope winch comprises the variable frequency motor, a winch rack, a roller rack, a hydraulic disk brake, a rope arranging mechanism and a monitoring system. The variable frequency motor and the roller rack are arranged on the left side and the right side of the winch rack respectively; the roller rack is horizontally provided with a winch central shaft which is connected with the roller rack through a bearing, and the inside of the roller rack is provided with a roller which is connected with the radial outside of the winch central shaft; the left end of the winch central shaft extends out of the roller rack and is connected with the driven plate of an electromagnetic clutch through a connection board, the output shaft of the variable frequency motor is connected with the input shaft of a reducer gearbox, and the output shaft of the reducer gearbox is connected with the driving plate of the electromagnetic clutch through a shaft sleeve; the rope arranging mechanism is arranged above the roller rack, and ropes are wound onto the roller through the rope arranging mechanism; the monitoring system comprises a rope length and rope speed sensor, a tension testing mechanism and a monitoring computer. The intelligent deep hole rope winch driven by the variable frequency motor has the advantages of high efficiency, safety, intelligent control, energy saving and environmental protection.

Description

technical field [0001] The invention relates to geological drilling equipment, in particular to an intelligent deep hole rope winch driven by a frequency conversion motor. Background technique [0002] With the rapid development of the national economy, the society's demand for various resources has increased accordingly, and deep exploration and prospecting have become the main target of my country's geological work. With the continuous development of the wireline coring technology, the wireline winch has increasingly become one of the important components in the drilling equipment. [0003] For deep hole coring, especially for continuous coring of 3,000 meters, salvage is particularly important. Every failure to salvage the core means the failure of a deep-hole high-intensity drilling operation. The frequent lifting and lowering of dozens of tons of drill strings requires huge power and manpower, which only increases useless auxiliary time. , and increases the accident r...

AI Technical Summary

Problems solved by technology

Although the failure of core salvage is caused by many factors, such as core shedding, inner pipe jacking, improper configuration of drilling tools, etc., the main reason for salvage failure is the technical failure of the rope coring winch itself or the difficulty in operation. one

[0004] At present, most geological exploration units use mechanical or hydraulic rope winches. Traditional mechanical rope winches generally have no rope arrangement and no monitoring device. They lag behind in depth, control, monitoring, stability, etc., and accidents occur frequently. In the process of deep hole drilling, it is very inconsistent with the technological requirements of wireline coring, and cannot meet the needs of the current development of geological core drilling

Although the hydraulic rope winch has been greatly improved compared with the mechanical type, it has the defects of complex hydraulic system, difficult to find fault points, difficult equipment maintenance, low hydraulic transmission efficiency, high energy consumption, and is not conducive to energy saving and emission reduction. Hydraulic oil is easy to leak during maintenance and cause environmental pollution
