Remote measuring and metering device for engineering construction

Abstract

The invention discloses a long-distance measuring and metering device for engineering construction. The long-distance measuring and metering device comprises a binocular laser emitting device, a measuring laser device clearance-free continuous adjusting mechanism, a flexible pre-tightening mechanism and a measuring head shell mechanism. The invention belongs to the technical field of laser ranging, and particularly relates to a long-distance measuring and metering device for engineering construction. A hydraulic transmission mechanism is additionally arranged between rigid transmission devices, the problem of measurement errors caused by mechanical clearance is solved, in addition, a flexible pre-tightening mechanism is creatively provided, pre-tightening force is provided for an arc-shaped cylindrical swing piston through a pre-compressed pre-tightening spring body, and the mechanical clearance is reduced. And under the condition that the sliding block has clearance, the sliding block is reversely pressed through the pre-tightening spring body, so that the sliding block is kept in a certain fixed state.

Description

technical field [0001] The invention belongs to the technical field of laser ranging, and specifically refers to a long-distance measuring and measuring device for engineering construction. Background technique [0002] In construction engineering, the construction of airport runways is an uncommon ultra-long-distance single construction project, and different from general road pavement, the take-off and landing runways of airports are not only long in distance, but also have a certain The straightness requirement is higher than that of ordinary paved roads. Therefore, when measuring various length data, it cannot be measured in sections like ordinary paved roads, but requires overall measurement of ultra-long travel. [0003] Due to the long measurement distance, the small deviation of the measurement starting position may be very obvious at the end position, but the general adjustment device is mechanically driven. Although the mechanical parts can be made extremely precis...

AI Technical Summary

Problems solved by technology

[0003] Due to the long measurement distance, the small deviation of the measurement starting position may be very obvious at the end position, but the general adjustment device is mechanically driven. Although the mechanical parts can be made extremely precise in modern industry, the mechanical rigidity The problem of gaps (movement gaps between parts) between transmissions has not been fundamentally overcome. As long as gaps exist, the test head will inevitably swing freely in a small range, which will affect the measurement results during long-distance measurement. influences
