Abstract

The invention discloses a mobile electronic projection device for measuring paying off. The device comprises a base body, a supporting rod, an inner sleeve and an outer sleeve. Supporting legs are arranged at the bottom of the circular-truncated-cone-shaped base body; a vertical supporting rod is arranged in the center of the upper surface of the base body; the inner sleeve sleeves the periphery of the supporting rod; through holes are evenly distributed in the pipe wall where the inner sleeve is located; and the through holes are filled with balls. The outer sleeve is connected to the outer wall of the inner sleeve in a sleeving mode and rotates on the outer wall of the inner sleeve; and a protruding edge protruding outwards is arranged at the bottom of the outer sleeve and is sleeved inan annular groove of the base body. A laser receiver is arranged at the top where the outer sleeve is located; and an annular laser transmitter is connected to the outer wall of the outer sleeve in asleeving mode. An accurate pay-off point position is accurately and rapidly located according to the mutual synergistic effect of the annular laser transmitter and the laser receiver. Moreover, the device is used conveniently; the labor cost is lowered; the pay-off time is saved; the pay-off speed is increased; the high pay-off point precision is ensured; and the engineering quality is guaranteedindirectly.

Description

technical field [0001] The invention belongs to the technical field of construction surveying equipment, and in particular relates to a mobile electronic projection device for measuring and setting out lines. Background technique [0002] As a production activity in the implementation stage of engineering construction, building construction is the construction process of various buildings. It mainly includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. [0003] In the construction process, in order to ensure the accuracy of the construction orientation, the flatness measurement is usually carried out on the leveled construction ground, and then in the existing measuring instrument setting-out, the horizontal distance is measured with a tape measure, and the positioning device is used to measure the When manually measuring the center and determining the direction at the same time, i...
