Description

Technical Field

[0001] This utility model relates to the field of well protection technology, and in particular to a temporary protective device for the partial removal of steel plates in wells. Background Technology

[0002] A ore pass is a vertical or inclined shaft connecting two or more stages for ore chuting. Also known as a ceiling, ore passes are used in mining operations. Because mines are often very high and ore transport is frequent, a shaft-like pipe is often dug from top to bottom in some mines to improve transport efficiency and save costs. Ore is poured directly from top to bottom, and transport vehicles wait underground for direct transport. Ore passes improve transport efficiency and, due to the direct vertical pouring, can also play a role in crushing the ore. They are mainly used for ore chute handling, personnel movement, material transport, ventilation, backfilling, and prospecting (see mine shafts). The cross-section is circular (diameter generally 1.2~2m), square, or rectangular (cross-section 1.5m×1.5m~2.5m×2.5m), and the height is generally 30~60m, sometimes reaching several hundred meters. Temporary protective devices are required when removing steel plates from a section of the ore pass.

[0003] However, in practical applications, it needs to be quickly disassembled and assembled. If it is inconvenient to disassemble and assemble, it will affect the positioning and installation of subsequent protective devices, thus reducing the ease of use of the component and affecting the efficiency of the device.
