An alarm device for a single clip type buffering sealed alarm wire line coring drilling tool

Abstract

The invention discloses a signalling device of a single-card type buffer-sealed signalling rope core drilling tool. The front end of the shaft is inserted in the rear end of the suspension ring seat and is connected with the rear end of the suspension ring seat by screw thread , the buffer pad, the bearing cover, the pair of bearings, the bearing seat and the large spring are respectively sleeved at the rear end of the shaft, and the pair of bearings are located at both ends of the bearing seat respectively, and the pair of bearings is formed by the front bearing and the rear bearing, the front bearing is located in the bearing housing, the buffer pad is in contact with the bearing housing, the rear bearing is in contact with the large spring, the nut is screwed on the rear end of the shaft, and the buffer pad, The bearing housing, the paired bearings, the bearing seat and the large spring are locked on the rear end of the shaft. The advantages of the present invention are: accurate reporting, which not only eliminates the error caused by manual judgment based on experience, but also effectively improves drilling efficiency. , and avoid the damage to the drilling tool caused by the core blockage, which can effectively protect the drilling tool.

Description

technical field [0001] The present invention relates to the technical field of signaling devices, more specifically to the technical field of signaling devices for core drilling tools. Background technique [0002] Rope core drilling tool is also called non-lifting core drilling tool. Its characteristic is that when the core is filled with the inner tube, the core is obtained by fishing the inner tube from the drill pipe with a rope fisher without lifting the drill. It has become the main means of prospecting in my country at present. At present, most of the wireline core drilling tools used by domestic prospecting enterprises do not have an alarm device. Operators cannot intuitively judge whether the core is filled with the inner tube, and can only judge whether the core is filled based on experience. However, manual judgment is often not accurate enough, and the drilling tool is often lifted before the core is filled with the inner tube, which affects the drilling efficien...

Problems solved by technology

At present, most of the wireline core drilling tools used by domestic prospecting enterprises do not have an alarm device, and the operator cannot intuitively judge whether the core is filled with the inner tube, and can only judge whether the core is filled with experience

However, manual judgment is often not accurate enough, and the drilling tool is often lifted before the core is filled with the inner tube, which affects the drilling efficiency; if the drilling tool is blocked during the drilling process, it is difficult to find it in time according to manual judgment. Very easy to cause serious damage to the drilling tool

At present, the drilling tools with reporting devices on the market are often complicated in structure, expensive and easy to damage.
