Description

Pulser extracting tool

Technical Field

The utility model belongs to the technical field of oilfield production equipment, and particularly relates to a pulser dismounting tool.

Background

All parts of the underground pulser need to be disassembled for primary maintenance after each use, so that the frequency of disassembling the underground pulser is high. The special dismounting tool is arranged when the shutoff valve component and the shutoff valve filter screen are dismounted, but when various outer cylinders of the shutoff valve, the shutoff valve filter screen and the electromagnetic coil driver are dismounted, the outer cylinders with larger screwing force are screwed and dismounted by using pipe tongs at present. On the one hand, the jaw of the pipe wrench is a plane, time and labor are wasted in bayonet and screwing, and the pipe wrench is not easy to operate, on the other hand, the screw die of the pipe wrench is easy to damage the outer surface of the outer cylinder, and the damaged outer cylinder is easy to corrode after long-term use.

In order to overcome the defect of pipe pliers when screwing the outer barrel, the applicant designs a tool for disassembling the outer barrel of a downhole pulser (application number is CN 202222549192.4) in the month 10 of 2022. However, the disassembly tool has design defects in the use process, two nuts are required to be screwed by using a spanner when the outer cylinder is clamped, and usually one nut is screwed into a plurality of buckles and then the other nut is screwed into the outer cylinder, and the two nuts are alternately screwed to realize locking and clamping. The screwing space of the wrench is limited, and the wrench cannot be screwed in a whole circle, so that when the outer barrel is clamped tightly by screwing two nuts, time and labor are wasted, the efficiency is low, and the wrench is inconvenient to detach.

Detailed Description

Examples

Referring to fig. 1 and 2, a pulser removing tool comprises a pipe handle 1, a vertical plate 2, a sliding rod 3, an arc-shaped sawtooth rubber plate 4, an arc-shaped plate 5, a sliding plate 6, a supporting plate 7, a screw sleeve 8, a screw rod 9 and a rotating handle 10; the number of the arc-shaped plates is two, the arc-shaped saw-tooth rubber plates are welded on the inner sides of the vertical plate and the sliding plate respectively, and the number of the arc-shaped saw-tooth rubber plates is two and fixed on the inner sides of the two arc-shaped plates respectively through strong glue; the number of the sliding rods is two, and the sliding rods are respectively welded at the upper part and the lower part of the inner side of the left vertical plate; the sliding plates are sleeved on the two sliding rods, the supporting plates are welded at the end parts of the sliding rods, the threaded sleeves are welded on the central holes of the supporting plates, the screw rod is in threaded connection with the threaded sleeves, and the rotating handles are welded at the outer ends of the screw rod; the pipe handle is welded to the outer side of the vertical plate; the width of the arc-shaped sawtooth rubber plate is not less than 6 cm, the height of the sawtooth is not less than 6 mm, the thickness of the arc-shaped sawtooth rubber plate is not less than 1.2 cm, and the central angle corresponding to the radian of the arc-shaped sawtooth rubber plate is less than 120 degrees.

When the outer cylinders are disassembled by primary maintenance of the underground pulser, the screw is screwed outwards, and the screw is screwed to the end part of the screw to be flush with the end part of the screw sleeve. And then the sliding plate is slid outwards, and the two arc-shaped sawtooth rubber plates are sleeved at the screwing part of the outer cylinder. The screw rod is screwed by holding the rotating handle, and the screw rod pushes the sliding plate to enable the two arc-shaped sawtooth rubber plates to be locked on the outer cylinder. The connecting outer cylinder can be detached by holding the pipe handle to rotate the detaching tool. Since the outer cylinder serves as a connecting piece with a protective function, it is not subjected to a large bearing force during operation. The locking force of the screw coupling portion of the outer cylinder is not great. The outer cylinder with the outer diameter of 70 mm is detached for example, the diameter of the circle where the inner arc section of the arc-shaped sawtooth rubber plate is located is also 70 mm, so that the joint degree of the arc-shaped sawtooth rubber plate and the locked outer cylinder is maximum, and the locking effect is best. The inner arc section is 70 mm diameter dismounting tool can also dismount the outer cylinder with the outer diameter of 60 mm-80 mm, but a screw rod is screwed with larger force, so that the laminating degree of the rubber plate and the outer cylinder is optimal, and the outer cylinder can be locked and locked even though the locking effect is not as good as that of the outer cylinder with the diameter of 70 mm, and the outer cylinder can be dismounted. Compared with the mode that the outer cylinder is clamped and held tightly by screwing two nuts, the dismounting tool can clamp the outer cylinder only by screwing one screw. In addition, in the screwing process, the clamping force can be increased at any time by screwing the screw, so that the time and the labor are saved, the efficiency is high, and the device is economical and applicable.
