Description

Logging cable drum spindle nose dismounting device

Technical Field

The utility model belongs to the technical field of maintenance devices of oil exploitation detection equipment, and particularly relates to a device for disassembling a shaft head of a logging cable drum.

Background

The logging cable drum spindle head assembly is a part of the logging sled, and plays important roles of supporting the logging cable drum and bearing a logging instrument in the working and use of the logging sled. The cable drum rotates in the spindle nose seat through the spindle nose subassembly and rotates to release the cable of original winding on the cable drum and connect logging instrument on the cable and get into in the pit, carry out the logging operation. The spindle nose assembly not only plays a role in connecting and fixing the cable roller and the towing sledge, but also is a wear part rotating for a long time in the operation process. Whether the spindle head assembly is intact or not and the matching size of the spindle head assembly and the roller spindle are adjusted play a key role in stabilizing the whole logging device, so that the spindle head needs to be disassembled in daily inspection and disassembly and maintenance of the spindle head assembly.

Specifically, in the prior art, the spindle head assembly includes a spindle head and a tapered sleeve, an inner surface of the spindle head is matched with the tapered sleeve, and the tapered sleeve is extruded in a radial direction by sleeving the spindle head on the tapered sleeve, so that the spindle head and the tapered sleeve are fixed on the drum shaft together. In order to separate the shaft head from the tapered shaft sleeve, a barrel-shaped part with one end sealed is adopted at present to be sleeved on the roller shaft, and the end surface of the non-sealed end of the barrel-shaped part is adjacent to the end surface of the smaller diameter end of the tapered shaft sleeve. In the dismounting process, a copper hammer with a hammer head of more than eight pounds (about 3.6kg) can be used for hammering the blocking end of the barrel-shaped part, and the end surface of the non-blocking end impacts the conical shaft sleeve. Because the inertia of the shaft head is large, compared with the conical shaft sleeve, the shaft head is not easy to move, and therefore the conical shaft sleeve can move axially under the action of impact force, but the shaft head does not move or the movement distance is smaller than that of the conical shaft sleeve, so that the conical shaft sleeve is separated from the shaft head.

By adopting the disassembly mode, a plurality of operators are usually required to cooperate, the operation time is long, and the operation efficiency is low. In addition, the manual hammering mode is adopted for disassembly, the physical consumption of personnel in the disassembly process is large, and the personnel are easily damaged in the process. Moreover, the extracting tool itself has hidden danger, if strike inaccurate, the effect direction of the position deviation of colliding or the impact force is deviated, may cause the damage to the axle even can cause operating personnel to be injured. Finally, when the shaft head which is very difficult to disassemble is encountered, the shaft head must be disassembled destructively, so that the shaft head is scrapped, and the maintenance cost is obviously increased.
