A semi-automatic construction pay-off instrument

Abstract

The invention discloses a semi-automatic construction pay-off instrument, which comprises a drive device, a centering device, a pay-off device, and a control device. Drive wheels are symmetrically arranged on the left and right wheel shafts of the front frame and the rear frame of the drive device. , driven wheel, the centering device includes a mounting plate, the laser transmitter chute of the mounting plate is equipped with a front laser transmitter, the left laser transmitter and the right laser transmitter of the centering device pass through the right-angled mounting plate respectively It is symmetrically installed on the wheel axles on the left and right sides of the rear frame. The wire-releasing device includes an ink tank, the rubber conduit at the bottom of the ink tank is connected with the wire-releasing needle, and the control device includes a remote controller. The invention adopts crawler drive, laser centering, and replaces the traditional hand-held red and blue pencils with the pay-off needle, without theodolite and ink fountain, and only one person can complete the construction lay-out task, saving time and effort, accurate pay-off, and high pay-off speed It is fast and can work continuously day and night in complex construction environments.

Description

technical field [0001] The invention relates to a semi-automatic construction setting-out instrument for construction engineering, in particular to a semi-automatic construction setting-out instrument. Background technique [0002] At present, the main instrument for setting out lines in construction projects is the theodolite. The general method is: install the theodolite at a known measuring point, one person operates the theodolite, and the other holds a red and blue pencil in the dotting direction. According to the command of the person operating the theodolite, each Determine a point on the ground at a certain distance, and two people use an ink fountain to release the connection line between the two points to complete a section of construction. When there is noise, it is necessary to move the theodolite many times. When encountering uneven objects, this method cannot even be used to pay off the wire, which will affect the construction.
