Horizontal measurement instrument provided with dry iron rack

Abstract

The invention discloses a horizontal measurement instrument provided with a dry iron rack. The horizontal measurement instrument comprises a mixing ruler which is provided with a press fit device. The top of the press fit device is located in the mixing ruler which is movably connected with the press fit device. A horizontal ruler is mounted on one side of the press fit device, and an iron ruler is mounted on the other side of the press fit device. The iron ruler and the horizontal ruler are located on the same horizontal plane and connected through fastening steel nails. The horizontal ruler is provided with and movably connected with an expansion head which is of a rectangular structure, and the expansion head is arranged on the horizontal line on the outer side face of the horizontal ruler. One side of the expansion head stretches into the horizontal ruler, and the other side of the expansion head stretches out of the horizontal ruler. A rectangular hole is formed in the portion, close to the bottom, of the horizontal ruler. The horizontal measurement instrument provided with the dry iron rack is compact in structure, easy to operate, capable of accurately controlling the deformation difference after being stretched and suitable for patching and reinforcing of a reshaped casing deformation well, the reshaped casing deformation well is large in diameter after being reinforced, a good pressing effect can be achieved, the structural performance is good, and the service life can be effectively prolonged.

Description

technical field [0001] The invention relates to a level measuring instrument provided with a dry iron frame. Background technique [0002] Casing damaged wells must be sealed and reinforced after grinding and shaping, so that they can be produced and processed normally. Although the general subsidy tool can meet the production requirements in terms of strength and sealing performance after being subsidized, its internal diameter is small, it cannot be well reinforced, and the anchoring effect is poor. Therefore, it is necessary to target this series Issues are targeted for reinforcement. Although the inner diameter of existing subsidy tools has reached certain requirements, the inner diameter still cannot meet the requirements of conventional layered mining tools, and it is necessary to improve it so that it can be better sealed and reinforced, and It will not affect normal processing and production. Contents of the invention [0003] The technical problem to be solved ...
