Integrally-suspended gravitational levelling type laser measuring instrument for building

Abstract

The invention discloses an integrally-suspended gravitational levelling type laser measuring instrument for a building. The instrument comprises a main instrument frame, wherein gear racks which are matched with gears through a gear shaft are arranged at two sides of the upper part of the main instrument frame; a group of movable transverse racks is arranged in the main instrument frame in a sliding manner; sliding racks which are engaged with the gears are arranged at the upper parts of the movable transverse racks; the end parts of the movable transverse racks are connected with side frames which are in match with lifting oil cylinders; a slide seat is arranged at the lower part of the main instrument rack in a sliding manner, and a connecting rod is arranged at the lower part of the slide seat; an angle ruler is arranged at the lower part of the connecting rod, and the bottom end of the connecting rod is in rotating fitting with a main machine of the measuring instrument. According to the integrally-suspended gravitational levelling type laser measuring instrument for the building, the span and the height can be flexibly adjusted; meanwhile, the levelness of the main machine of the measuring instrument can be ensured, and the main machine of the measuring instrument be accurately transversely moved and rotated by angles during being operated, so that the building measurement accuracy can be ensured.

Description

technical field [0001] The invention relates to the field of architectural laser measuring instruments, in particular to an integrally suspended gravity-anping architectural laser measuring instrument. Background technique [0002] In building construction, in order to ensure the accuracy of the levelness or verticality of the building structure, various auxiliary instruments are often used. Among them, the frequency of use of the laser measuring instrument is quite high. Although the laser measuring instrument can measure and calibrate accurately and quickly, However, the level of its own placement position is not easy to control, and it is difficult to ensure the accuracy of the movement position when it needs to move. Now a laser measuring instrument with its own placement position adjustment and a certain accurate movement range is needed to solve the above problems. question. Contents of the invention [0003] The object of the present invention is to provide an inte...
