AI Technical Summary

Technical Problem

During railway track construction, total stations are easily damaged by impacts from debris or tools at the construction site, affecting measurement accuracy and work efficiency. Furthermore, traditional fixed total stations are difficult to inspect and disassemble, making it hard to meet the needs of efficient and precise construction.

Method used

A measuring instrument for railway track construction was designed. It adopts a protective box structure and achieves full-enclosed protection of the total station through the linkage of the lifting plate and the shielding plate. Combined with the fixing component and the folding component, the total station can be quickly disassembled and securely locked. It is also equipped with a level calibration structure to ensure measurement accuracy and work efficiency.

Benefits of technology

It effectively prevents damage to the total station at the construction site, improves measurement accuracy and work efficiency, simplifies maintenance procedures, reduces maintenance costs, adapts to complex construction environments, and ensures the efficiency and accuracy of track construction.

Abstract

This invention relates to the field of railway track measuring instruments, and discloses a measuring instrument for railway track construction. The instrument includes a car body, a protective box fixedly installed on the upper surface of the car body, a protective cavity with an upward opening inside the protective box, a lifting plate inside the protective cavity, a disassembly plate placed on the upper surface of the lifting plate, a total station fixedly installed on the upper surface of the disassembly plate, and a fixing component on the upper surface of the lifting plate. A shielding plate is located above the lifting plate, a shielding rod is located on the lower surface of the shielding plate, and a slot is opened on the upper surface of the shielding plate. Opposite folding plates are slidably installed in the slot, and a folding component is located on the upper surface of the lifting plate. A moving component is located on the upper surface of the car body. Through this structure, the sliding component drives the shielding plate to close the opening of the protective cavity, providing comprehensive protection for the total station within the protective box and preventing damage to the total station from collisions with construction site debris or tools during car body movement.
