Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
As shown in fig. 1 and 2: the utility model provides an automatic cloud platform of leveling of gravity type biax, including cross 4, upper bracket 2 and lower carriage 5, four ends of cross 4 are four spindle noses, it goes up articulated ear to stretch out two oppositions on the upper bracket 2, stretch out two oppositions down articulated ear on the lower carriage 5, the interval between the articulated ear is greater than the width of articulated ear down, four spindle noses of cross 4 wear respectively in the shaft hole of articulated ear and articulated ear down with upper bracket 2 and 5 swing joint of lower carriage, upper bracket 2 is fixed the back, two direction swings of mutually perpendicular can be followed to lower carriage 5. The bottom of lower carriage 5 is provided with laser plummet mount table 7, and the bottom of laser plummet mount table 7 is provided with weight 10, and the top of upper bracket 2 sets up the link, and the top of upper bracket 2 is provided with horizontally flange 1. The gravity center of the heavy hammer 10, the center of the laser plummet mounting table 7 and the axis of the cross shaft 4 are positioned on the same vertical line without the external force. The upper bracket 2 is arranged on the overpass through the connecting end, and the laser plummet installation platform 7 can be kept horizontal no matter which direction the installation surface of the overpass inclines towards, so that the ray of the laser plummet 6 on the laser plummet installation platform 7 is ensured not to be inclined.
In order to facilitate the disassembly and assembly of the laser plummet 6, a clamping rail 8 matched with the laser plummet is arranged on the laser plummet mounting table 7.
The laser plummet mounting table 7 is connected with the lower support 5 through a plurality of bolts, and other measuring instruments can be mounted on the lower support 5 according to construction requirements.
If the hinged part of the cross shaft 4 and the upper support 2 or the lower support 5 is too loose, the laser plummet 6 is easy to swing uncontrollably when wind blows in a construction site, normal construction monitoring is influenced, and therefore the damper 3 is assembled between the shaft head of the cross shaft 4 and the shaft holes of the upper hinged lug and the lower hinged lug. By installing the damper 3, the resistance of the cross shaft 4 during movement is moderately improved, and the influence of breeze on monitoring data is reduced.
