Foldable portable measuring device for highway construction

Abstract

The invention relates to the technical field of highway construction measurement, in particular to a foldable portable measuring device for highway construction. The device comprises a protective support, the protective support comprises a connecting disc, a penetrating groove is formed in the side face of the connecting disc, a rotating shaft is fixed in the penetrating groove, and a limiting plate is arranged on the penetrating groove; the rotating shaft comprises clamping plates which are of straight plate structures and annularly arrayed on the outer surface of the rotating shaft; a supporting rod is connected to the side face of the connecting disc, protection plates are arranged at the two sides of the supporting rod, the protection plates are of partial cylinder structures, and theprotection plates form a cylinder; and a rotating hole is formed at the upper portion of the supporting rod, the size of the rotating hole is matched with that of the rotating shaft, the rotating holeis rotationally connected with the rotating shaft, a connecting threaded hole is formed at the upper portion of the rotating hole, and a connecting bolt is in threaded connection with the interior ofthe connecting threaded hole. The device aims to solve the problem that a common bracket cannot protect a total station when the total station is moved.

Description

technical field [0001] The invention relates to the technical field of road construction measurement, in particular to a foldable portable measuring device for road construction. Background technique [0002] The road needs to be measured before construction, and the center line of the road is drawn to prevent deviations in the construction. At this time, a total station is needed. When the total station is used, it needs to be fixed on a bracket and the altimeter is lifted to facilitate measurement. Because the road is long and generally has There are many turns, and the total station needs to be moved in a large range. Since the ordinary bracket cannot provide protection performance during the movement, it needs to be disassembled from the bracket and put into a special protective box. When it is used again, it needs to be reinstalled. Assembly and adjustment, repeated loading and unloading are very troublesome. The purpose of the present invention is to provide a foldable...

[0002] The road needs to be measured before construction, and the center line of the road is drawn to prevent deviations in the construction. At this time, a total station is needed. When the total station is used, it needs to be fixed on a bracket and the altimeter is lifted to facilitate measurement. Because the road is long and generally has There are many turns, and the total station needs to be moved in a large range. Since the ordinary bracket cannot provide protection performance during the movement, it needs to be disassembled from the bracket and put into a special protective box. When it is used again, it needs to be reinstalled. Assembly and adjustment, repeated loading and unloading are very troublesome. The purpose of the present invention is to provide a foldable portable measuring device for road construction to solve the problem that the general support cannot protect the total station when it is moved.
