Description
Technical field
The utility model relates to a kind of reverse locating devices of laser plummet, project vertically downward for laser plummet
Anchor point belongs to Construction of Civil Engineering field of measuring technique.
Background technique
Laser plummet belongs to one kind of laser mapping instrument, for measuring small horizontal departure, the lead of opposite plumb line
Point transmitting, the measurement of object vertically profiling and the vertical transmission in orientation of vertical line, in construction, high tower, chimney, electricity
Ladder, the construction and installation of heavy mechanical equipment, Engineering Deformation Observation field are widely used.The laser of majority producer production at present hangs down quasi-
Instrument is only capable of the upward perpendicular projection of laser, and for this single limitation, domestic existing research mechanism is transformed it, warp
Improved plumb aligner can provide horizontal plane benchmark, to carry out horizontal plane mapping operations, this is solved to a certain extent
The narrow limitation of laser plummet location fix.In recent years, some enterprises start production can and meanwhile two sides up and down
To the plumb aligner of projection, but the precision projected downwards is far below upward projection precision.With engineering project type increasingly
It is more, the work that target is carried out positioning transmitting downwards is also constantly generated, and precision prescribed is higher and higher.Such as similar perpendicular
Well etc. to the ground construct for engineering by the following underground constructed, need in the construction process downward high-precision Delivery Center axis or
Central point, the downward transmitting accuracy of current laser plummet have been unable to meet requirement.Therefore, in order to keep laser plummet high-precision
It spends downward cultellation to be applied in engineering field, needs to make a kind of dress that laser plummet can be inverted, fix and adjusted
It sets.
Utility model content
The purpose of this utility model is to provide a kind of structures, and laser plummet simple, easy for installation reverse-locates dress
It sets, it is low to solve the problems, such as that laser existing for current laser plummet projects precision downward vertically, without to laser plummet structure
In the case where making any change, improves laser plummet laser and project precision downward vertically.
The technical scheme in the invention for solving the technical problem is such.A kind of laser plummet it is reversed fixed
Position device includes pedestal in structure, and the connecting column fixed vertical with pedestal, connection top end is fastenedly connected positioning plate, positioning plate
Center is provided with hole, and top surface is fixed with positioning ring, and guide groove is provided on positioning ring, wears and is connected to for being connected and fixed in guide groove
The standing screw of laser plummet.Centre is provided with sight vane in the base, and the upper surface of pedestal is fixed with reflective mirror, the following table of pedestal
Face is equipped with the cored screw for connecting with laser plummet bracket.
Pedestal is connect with positioning plate by three connecting columns, and level is wired to equilateral triangle between three connecting columns,
It is exactly 120 ° of horizontal sextant angle between three connecting columns.
The reflective mirror of pedestal upper side is in discontinuous, annular flat sheet, inlays and is fixed on the base.
When in use, the cored screw of the device pedestal is put into circular hole at the top of tripod, utilizes gasket, instrument suppotr frame torr
Device and tripod are connected and fixed by plate, fixture nut, and laser plummet is inverted to bottom and is put into device upwards, with fixed spiral shell
Bar is connect with laser plummet, levels laser plummet by reflective mirror, adjustment guiding groove location is aligned to laser plummet to be thrown
Exit point reaches centering leveling.
The beneficial effects of the utility model are: the device cost of manufacture is cheap, easy to operate, without to laser plummet
In the case that structure makees any change, directly laser plummet is mounted on reverse locating device and is used, improved laser and hang down
Quasi- instrument laser projects precision downward vertically.

Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Referring to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of reverse locating device of laser plummet, pedestal 4 is disk
Shape, upper surface in a ring, sheet, inlay and be fixed with reflective mirror 12, pedestal center is provided with sight vane 15, and lower surface is fixedly connected
There is the cored screw 1 of outer mantle fiber, for connecting with laser plummet bracket.Pedestal 4 and positioning plate 8 pass through connection post holes 17 and three
The connecting column 5 of root both ends mantle fiber connects, and level is wired to equilateral triangle between three connecting columns, that is, three connecting columns it
Between 120 ° of horizontal sextant angle, by spring washer 6, fastened with connecting column nut 7, form pedestal 4, positioning plate 8 and connecting column 5 whole
