Description

Integrated device for rope coring winch automatic arranging, weighing and sounding

technical field

The utility model relates to an integrated device for automatically arranging rope, weighing, and sounding for a rope coring winch.

Background technique

Wireline core drilling technology is an important core drilling method in today's drilling production. Since the 1970s, my country has successively developed wireline coring tools suitable for drilling under various conditions and with different specifications, but the overall structure of the wireline coring winch with many defects has not changed. Ordinary rope coring winches do not have an automatic rope arrangement, and cannot carry out weighing and sounding. During use, there are often phenomena such as rope disorder, stacking and pressing, which make the winch unable to work normally, and often overload and damage parts. Parts and drilling workers are injured, the spear head is not in place and runs empty, and the wire rope is over-loaded and piled up.

In our country, the research on the automatic rope arrangement mechanism of the winch began in the 1990s. At that time, the automatic rope arrangement mechanism was not used for the rope coring winch, but for the winch in the transportation lane of the mining production area. During the same period, with the rapid development of well logging technology, the cable winch for lowering the well logging equipment also put forward requirements for the automatic arrangement of cables, so the automatic rope arrangement mechanism of the well logging winch also appeared. In recent years, with the rise of electromechanical-hydraulic integration technology, various automatic rope-releasing mechanisms have also appeared one after another. At present, the automatic rope unwinding devices used in coal mines, well logging, drilling and other industries mainly include mechanical, electric, hydraulic and pneumatic devices. The versatility is poor, it is only suitable for a certain industry or a certain type of winch, and there are also disadvantages of high manufacturing cost and low integration. There are fewer types of automatic rope-discharging devices that should be used for rope coring winches, and there is no general promotion. It is even less common for rope coring winches with multiple functions such as automatic rope arrangement, weighing, and sounding.

The automatic rope arrangement mechanism of the utility model uses the reel as the power source, drives the double helical shaft to rotate through chain transmission deceleration, and the double helical shaft and the slider form a helical transmission. During the transmission process, when the slider moves in the spiral groove, the slider The connecting bolts push the sliding box to slide along the axial direction of the sliding shaft. Since the spiral groove is a closed groove composed of a left-handed groove and a right-handed groove, when the slider slides to the top of the spiral groove, it will automatically reverse direction, and then drive the sliding box along the sliding axis. Sliding back and forth, the guide rollers can guide the steel wire ropes to regularly deviate left and right along the axis of the drum, so that the wire ropes are neatly arranged on the drum automatically.

The basis of the sounding mechanism of the present utility model for recording the depth is the length of the lowered wire rope. During the working process, no matter whether it is lowering the spear head or lifting the spear head, the wire rope has a certain tension, so that there is a certain friction between the wire rope and the sounding roller, which drives the sounding roller to rotate, and the roller shaft will also rotate accordingly. The encoder and the roller shaft are connected by a coupling, so the rotational speed of the rotating shaft of the rotary encoder is synchronized with the sounding roller. The rotary encoder converts the measured rotation angle into a digital signal and transmits it to the digital display meter A. After simple calculation, set the length value represented by the corresponding pulse signal on the digital display meter A to display the length value of the wire rope lowering or lifting, and then display the depth value of the spearhead in the wellbore.

In the weighing mechanism of the utility model, the steel wire rope changes the direction of the steel wire rope through the three rollers of the sounding roller, the weighing roller and the guide roller. The three rollers make the steel wire rope form a 120° included angle, and the pressure sensor is installed on the 120° included angle. On the line, due to the knowledge of force synthesis, the equivalent pressure on the weighing roller bearing is equal to the tension value of the steel wire rope. The weighing roller transmits the pressure to the roller support frame through the shaft, and the roller support frame directly acts on the pressure sensor. Then The pressure acting on the direction of the pressure sensor is equal to the tension F of the wire rope, so the pressure measured by the pressure sensor is the tension of the wire rope. The pressure sensor transmits the measured signal to the digital display meter B through the signal line, and the digital display meter B displays the tension value on the wire rope in real time to realize the weighing function.
