Level gauge with pressing device

Abstract

The invention discloses a level gauge with a pressing device. The level gauge comprises a mixed ruler, wherein a pressure closing machine is arranged on the mixed ruler, and the top of the pressure closing machine is positioned in the mixed ruler; the mixed ruler is movably connected with the pressure closing machine; a level bar is mounted on one side of the pressure closing machine, and an iron ruler is arranged on the other side; the iron ruler and the level bar are on the same horizontal plane, and are connected via a steel fastening nail; an expansion head is arranged on the level bar, is movably connected with the level bar, is a rectangular structure, and is arranged on the horizontal line of the lateral surface of the level bar; one side of the expansion head extends in the level bar, and the other side of the expansion head extends outside the level bar; the level bar is provided with a rectangular hole close to the bottom. The level gauge with the pressing device is compact in structure, easy to operate, applicable to patching and reinforcing after reshaping of a casing deformation well, high in structural performance and low in damage rate, the deformation difference after extension can be accurately controlled, and the service life can be effectively prolonged.

Description

technical field [0001] The invention relates to a level measuring instrument provided with a pressing device. 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...
