A kind of plastering machine of following datum fast and positioning
Technical field
The present invention relates to a kind of plastering machine, particularly relate to a kind of plastering machine adopting laser level to position.
Background technology
Plastering machine is alternative, and manually on body of wall, spread cement mortar has the advantages such as efficiency is high, time saving and energy saving less manpower.
Existing plastering machine is provided with upright track and main frame of plastering, and when main frame of plastering moves up and down along upright track, correspondence completes and plasters and press polish two work.Allow " straightening " that first must will complete plastering machine before plastering machine work.The object of " straightening " makes the production forming surface of plastering machine vertical, and allow the distance between production forming surface and metope be target range.Production forming surface refers to the external surface of the cement sand bed smeared on the wall.Because the vertical bury pipe of production forming surface and flatness are mainly decided by the parallelism of the vertical bury pipe of upright track and the left track of upright track and right track.Although the left track longitudinal axis of upright track and right track longitudinal axis are designed to (plane at left track longitudinal axis and right track longitudinal axis place is called orbital plane) coplanar and parallel to each other, but foozle and the impact of rigging error on the verticality of described upright track and parallelism but have more serious impact, this precision that result also in production forming surface in fact more departs from expection.So must, by " straightening " work, allow the left track longitudinal axis of upright track and right track longitudinal axis be in the position meeting required precision.Can only complete a slice area owing to plastering at every turn, a face wall needs point to have plastered several times often.This just makes plastering machine plaster several times in process at this, all needs to carry out " straightening " respectively.This introduces another requirement to " straightening ": posterior production forming surface is enough concordant with production forming surface formerly.
Current plastering machine carries out " straightening " 2 kinds of schemes usually: 1) get location ready on the wall in advance; 2) inclinator is adopted to measure the angle of upright track.But the former efficiency is very slow, and the latter maybe can exist unacceptable error.And use inclinator also to need to make a call to below plastering machine in advance one to be ranked the inclination angle of upright track after site is first located the chassis of plastering machine, could be adjusted.The efficiency that so at present " straightening " works is all lower, and error is also large.
So need to improve existing plastering machine, to obtain higher efficiency of construction.
