Abstract

The invention relates to the field of monitoring positioning, in particular to a laser positioning system, and specifically discloses a laser positioning system applicable to tower crane construction at night. The laser positioning system applicable to tower crane construction at night comprises a vertical positioning device and a laser emitting device, wherein the laser emitting device comprises a power supply and a laser emitting unit. The laser positioning system applicable to tower crane construction at night enables laser beams to keep vertical downward all the time, so that a tower crane can be rapidly positioned to the vertical position of a hook in construction at night, and the construction efficiency at night is improved; meanwhile, operators below are reminded to be prevented from being hurt by mistake by hoisted objects above, and visual dead zones of a tower crane driver and signalmen are eliminated; moreover, even though a positioning ball swings, the swing angle of the positioning ball is within 3 degrees under the effects of a left baffle and a right baffle, so that the error of the laser beams is within 1 meter, and further, the rapid and accurate positioning can be carried out.

Description

technical field [0001] The invention relates to the field of monitoring and positioning, in particular to a laser positioning system, in particular to a laser positioning system suitable for tower crane construction at night. Background technique [0002] Along with the needs of economic development and urban construction, more and more construction sites have appeared in various cities. Tower crane, as the most commonly used lifting equipment on construction sites, is used to lift steel bars, corrugated wood, concrete, steel pipes and other raw materials for construction, and is an indispensable equipment on construction sites. Most construction sites, in order to catch up with the construction progress, usually carry out construction at night. The traditional tower cranes have the following disadvantages during night construction: 1. Since the traditional tower cranes are mainly directed by signal workers on the ground, the tower (tower crane driver) is only Simple operat...
