An anti-vibration device with automatic unlocking and follow-up for slender drill pipe

Abstract

The invention relates to a long and thin drill pipe anti-vibration device capable of automatic unlocking and follow-up. The long and thin drill pipe anti-vibration device includes a locking mechanism,a releasing mechanism and a bearing frame, the middle of the bearing frame is provided with a through hole for placing an external drill pipe, and the free end of the bearing frame is fixedly connected with the releasing mechanism; the bearing frame is fixedly provided with the locking mechanism; during initial installation, the releasing mechanism is fixedly connected with an external structure,when the external drill pipe is drilled, a drilling rig at the top end of the external drill pipe moves toward the bearing frame, the drill rig is fixedly connected with the locking mechanism, and the bearing frame is coupled with the external drill pipe, so that fixed connection between the releasing mechanism and the external structure is released. The long and thin drill pipe anti-vibration device capable of automatic unlocking and follow-up can be used for anti-vibration protection of long and thin type drill pipes with large draw ratios, and meanwhile has the functions of automatic unlocking and follow-up when the drill pipe at work.

Description

technical field [0001] The invention relates to an anti-vibration device for slender drill rods that can be automatically unlocked and moved, and belongs to the technical field of anti-mechanical environment structure mechanisms. The device is suitable for anti-vibration requirements of slender rods that need to be automatically unlocked and followed in aviation, aerospace and civil fields. Background technique [0002] Traditional anti-vibration devices mostly use fixed constraints, and their functions are relatively single. If there are follow-up actions, human participation is required to complete them. For example, the CN201110401986.X of Ocean King (Dongguan) Lighting Technology Co., Ltd. The patent of buckle lamps provides a kind of anti-vibration buckle, which includes an upper pressing piece and a lower pressing piece hinged with the upper pressing piece. A hook is hinged on the upper pressing piece. An upper mounting plate and a second upper mounting plate, both th...

AI Technical Summary

Problems solved by technology

[0004] The technical problem of the present invention is: to overcome the deficiencies of the prior art, a kind of anti-vibration device that can be automatically unlocked and moved for the slender drill pipe is proposed, which solves the mechanical problem of the slender drill pipe with the length-to-diameter ratio greater than 90:1. In the vibrating environment, due to the problem of damage due to excessive amplitude, it can be automatically unlocked according to the working conditions and follow up with the drilling rig driving the drill pipe, without affecting the normal drilling action of the drill pipe
