Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tools, and in particular relates to a conveniently fixed measuring instrument. Background Art

[0002] With the rapid development of the railway industry, the basic structure of the railway industry's quasi-specified lines has been changed from the original cube to a cylindrical form. Therefore, the "coincidence" of the center (center of the circle) of the line tower foundation cylinder and the center of the anchor bolts in the square pre-embedded mode has become the most important key process for the transmission line tower foundation sequence detection.

[0003] Through patent search, it was found that a coincidence measuring instrument for the center of the power tower foundation pile and the center of the anchor bolt with the publication number CN110243266A belongs to the field of measuring tool technology. It includes a base, at least two positioning rods are fixedly connected to the bottom end of the base, and the positioning rods are provided with a fine-tuning bolt body perpendicular to the positioning rods at the end away from the base. The base is provided with a measuring module capable of multi-directional distance measurement, and the extension direction of the measuring module is parallel to the top surface of the base. The coincidence measuring instrument uses a leveling module arranged at the bottom end of the base and a measuring module axially mounted on the top end of the base. The leveling module can be operated to arbitrarily adjust the measuring direction of the measuring module while keeping the base in a horizontal state. It has high flexibility, greatly improves the measurement efficiency, and can be completed by a single person.

[0004] Although the above technical solution can arbitrarily adjust the measuring direction of the measuring module, it is highly flexible and greatly improves the measuring efficiency. However, the above technical solution only fixes the measuring instrument side by attracting the positioning magnetic strip and the anchor bolt. When there is strong wind from the outside or it is accidentally touched by humans, it is easy to cause the positioning magnetic strip to separate from the anchor bolt, and the position of the measuring instrument moves, so that the center position is offset, which affects the subsequent work. Therefore, a measuring instrument that is easy to fix is ​​needed to solve the above technical problems. Utility Model Content
