New structure is simple, easy to operate, practical, can observe and adjust at any time the horizontality of forced centering base,
Improve measurement accuracy.
It is preferred that, horizontal bubble is located at the position that support plate edge is easy to observation, it is to avoid measuring instrument blocks water after installing
Flat bubble.First pass through operation governor motion by support plate regulation arrive horizontality when, then measuring instrument is installed, passes through horizontal gas
Bubble observation confirms that support plate is in horizontality；Measuring instrument can also be first installed, then again by operating governor motion to combine
Support plate regulation is arrived horizontality by horizontal bubble.Improved the utility model based on prior art, the bottom on chassis can be consolidated
Determine built-in fitting, be embedded in concrete observation pier, as permanent forced centering base, and can set anti-on the utility model
Protection unit is protected by；Due to pouring the factors such as error or setting of ground, it can be found by horizontal bubble, support plate will be in
Non-standard state, now only need to be by operating governor motion, you can support plate is recovered horizontality, it is to avoid measuring instrument is installed
Afterwards, error is caused during measurement.The bottom on the utility model chassis can assemble tripod, as portable forced centering base, lead to
The fine setting of mechanism is overregulated, support plate is in horizontality.
As shown in Figures 2 and 3, the present embodiment specifically discloses the one form of which of governor motion.Based on this implementation
The further optimization of example, in another embodiment, the governor motion include the multiple pins 4 for being fixed on the lower end of support plate 2,
With the multiple bolts 5 being assemblied in support plate 2, the support plate 2 is assemblied on chassis 1 by pin 4, and passes through swivel bolt
5 adjust support plates 2 with the spacing on chassis 1 to realize the Level tune of support plate.The purpose of design of pin is, is easy to support plate
Positioning and installation.When being rotated down 1 bolt therein, due to the effect of bolt, the bolt orientation support plate will be increased
With the spacing on chassis；When rotating up the bolt again, due to losing the effect of bolt, while in support plate gravity or elastic force
Under effect, the spacing on the bolt orientation support plate and chassis reduces immediately, so as to reach the mesh of the horizontality of regulation supporting plate
's.Adjusted by the combination of multiple bolts, you can realize support plate Level tune.
Further, in another embodiment, each bolt 5 is in same circumferencial direction.It is easy to implement support plate
Level tune.
Further, in another embodiment, the bolt 5 has 3.Certain bolt can also be 4 or more, due to
It is not that can determine that 1 plane at collinear 3 points, excessive bolt will be unfavorable for the Level tune of support plate.It is preferred that,
Pin has 3, on the inside or outside of bolt.
Further, in another embodiment, the screw thread of the bolt 5 is fine thread.It is easy to finely tune the water of support plate
Level state.
Further, in another embodiment, the thread surface of the bolt 5 is provided with wearing layer.Bolt can be improved
Service life.For example, wearing layer is titanium nitride.
Further, in another embodiment, the head of bolt 5 has the ear 51 for swivel bolt, or/and tool
There is the scraggly lines 52 for swivel bolt.It is easy to manual levelling to adjust support plate, it is convenient and swift.For example, ear can
Think open type or enclosed, lines can be variously-shaped for bar shaped or rhombus etc., is easy to swivel bolt, as shown in Figure 3 and Figure 5.
Certainly, bolt head can also be outer-hexagonal bolt head, or bolt head is simultaneously Triangle ID, interior five jiaos or hexagon socket head cap screw
Head.
As shown in fig. 6, the further optimization based on the present embodiment, in another embodiment, sets in the horizontal bubble 3
It is equipped with center graduation mark 31.It is easy to observation to judge whether support plate is in horizontality.
Further optimization based on the present embodiment, in another embodiment, the chassis 1 and support plate 2 are stainless steel.
Service life of the present utility model can be increased, it is ensured that accuracy of the present utility model.Certainly, chassis and support plate can also be
The anti-atmospheric corrosion material such as copper or copper alloy.Chassis can be split-type structural, i.e., can accommodate pin in the welding of plate body bottom
Boss, save material, as shown in Figure 2；It can also be monolithic construction.
Embodiment 2
The difference from Example 1 of embodiment 2 is that the structure type of governor motion is different.
As shown in Figure 4 and Figure 5, the present embodiment specifically discloses another form of governor motion.The governor motion
Including multiple bolts 5, and it is set with multiple springs 6 on each bolt 5, the support plate 2 is by bolts assemblies in chassis 1
On, and link spring 6 with support plate 2 to realize the Level tune of support plate by swivel bolt 5.During using the utility model,
Gap is left between support plate and chassis, spring is in free state.When being rotated down 1 bolt therein, due to bolt
Effect, will reduce the spacing of the bolt orientation support plate and chassis, then when rotating up the bolt, should due to the effect of spring
Bolt orientation support plate and the spacing on chassis increase immediately, so as to have adjusted the horizontality of supporting plate；Pass through multiple bolts
Combination rotation regulation, you can realize support plate Level tune.Chassis can be split-type structural, i.e., in the welding of plate body bottom
The boss of bolt can be accommodated, material is saved；Can also be monolithic construction, as shown in Figure 4.
The governor motion of the design can also be another assembling form, i.e., when using the utility model, and spring is in pressure
Contracting state, is that fit-state is gapless between support plate and chassis.When rotating up 1 bolt therein, due to spring
Effect, will increase the spacing of the bolt orientation support plate and chassis, when rotating the bolt still further below, should due to the effect of bolt
Bolt orientation support plate and the spacing on chassis reduce immediately, so as to have adjusted the horizontality of supporting plate；Pass through multiple bolts
Combination rotation regulation, you can realize support plate Level tune.
It is in summary, simple in construction using a kind of forced centering base for fine measuring instrument of the present utility model,
It is easy to operate, it is practical, the horizontality of forced centering base can be observed and adjusted at any time, measurement accuracy is improved.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
