Mechanical disassembly worktable and work method of waterproof two-way rod with cables at two ends

Abstract

A mechanical disassembly worktable of a waterproof two-way rod with cables at two ends is characterized by comprising a base, a substrate, a waterproof two-way rod clamp groove, a sliding wrench assembly, a cable extractor and a rubber sealing ring driller. In a disassembly mode, the sliding wrench assembly and the cable extractor are fixedly mounted on the base, and a power output end of the sliding wrench assembly is matched with a sealing cap at the end of the waterproof two-way rod placed in the waterproof two-way rod clamp groove. In a cleaning mode, the rubber sealing ring driller is fixedly mounted on the base, and a power output end of the rubber sealing ring driller is matched with a rod body end rubber sealing ring of the waterproof two-way rod without a cable and the sealing cap in the waterproof two-way rod clamp groove. The mechanical disassembly worktable has the advantage that workers can perform single-hand alternate operation by the aid of a fixing device and a lever device provided with the worktable in the whole disassembly cleaning process. Moreover, damage to the cable, incomplete cleaning of the rubber sealing ring and damage to an internal thread of a rod body can be avoided.

Description

[0001] (1) Technical field: [0002] The invention relates to the field of petroleum seismic physical exploration, and relates to a mechanical workbench and a working method capable of efficiently dismantling seismic line detectors and waterproof two-way rods. [0003] (two) background technology: [0004] The 408XL instrument and the 428XL instrument used in petroleum seismic physical exploration operations are equipped with geophone series measuring line cable plugs. Because land cables and offshore cables use different geophone string cable plugs, a large number of geophone strings need to be interchanged with land cable plugs or sea cable plugs every year. The key work of replacing the cable plug is to disassemble the waterproof two-way rod to separate the cable plug from the detector string. At present, there are no special auxiliary tools for this work, all of which are disassembled by hand using simple tools. A skilled operator disassembles about 45 per day, and there ...

AI Technical Summary

Problems solved by technology

(3) At the same time, due to the extrusion of the rubber sealing ring between part of the sealing nut and the cable, it is difficult to separate the cable and the sealing nut

(4) Since the aging rubber sealing ring is bonded to the rod body, the space at both ends of the rod body is narrow and threaded, so it is time-consuming and laborious to remove the aged rubber sealing ring

The above reasons lead to labor-intensive manual disassembly, and many workers suffer from muscle strain, frozen shoulder, and hand tenosynovitis and other strain diseases

Manual disassembly still has problems such as damaged cables, incomplete removal of rubber sealing rings, and damaged threads in the two-way rod.
