Specific embodiment
For the present invention aforementioned and other technology contents, feature and effect, in following cooperation with reference to figures 1 through Figure 15 pairs
In the detailed description of embodiment, can clearly it present.The structure content being previously mentioned in following embodiment is attached with specification
Figure is reference.
Each exemplary embodiment of the invention is described below with reference to accompanying drawings.
Embodiment one, the present invention are road construction measuring device, including bottom plate 1, and the bottom plate 1 is used to be subsequent knot
Structure provides immobilizing foundation, which is characterized in that and it is universal on the bottom plate 1 to be connected with balancer 2, specifically, in the bottom plate 1
Centre is fixedly connected with universal joint, and the universal joint other end is fixedly connected on 2 lower end of balancer center, and ball can be used in the universal joint
Other common constant velocity cardan joints can also be used in type constant velocity joint, and the balancer 2 is for installing measuring instrument, such as
Level, theodolite etc. are relatively fixed device specifically, can open up on the balancer 2 with corresponding instrument, and will with this
Instrument is fixed on balancer 2, which is the common fixed installation mode of existing measurement tripod, therefore is not existed
This is specifically described, and balancing device is provided between the balancer 2 and bottom plate 1, the balance dress can be inclined in bottom plate 1
In the case of still keep the level of balancer 2, to guarantee that measuring instrument has good measurement environment, 1 side of bottom plate turns
There are three supporting legs 3 for dynamic connection, and the supporting leg 3 is used to support bottom plate 1, in order to which survey crew preferably measures；
The balancing device includes the hollow sump 4 being fixedly connected on the bottom plate 1, in the sump 4 up and down
Kickboard 5 is slidably connected, is filled with water in the sump 4 in the space of 5 lower end of kickboard, 5 floatability of kickboard is in water
On face, 4 inner sidewall palette of the kickboard 5 and sump, when sump 4 tilts, under the effect of gravity, the water surface remains unchanged
Keep horizontal so that kickboard 5 it is also the same keep horizontal, 5 upper end of kickboard is fixedly connected with several support columns
6,6 upper end of support column passes through the sump 4 and 2 lower end surface of balancer connects, i.e. the sump 4
Upper surface offers several through-holes, and support column 6 passes through 2 lower end face contact of through-hole and balancer, the present embodiment when specifically used,
Survey crew only needs first to strut supporting leg 3, shake bottom plate 1 steadily will not and topple over, measuring instrument is fixedly mounted later
On balancer 2, because of the effect of water in sump 4, the kickboard 5 is set to remain balance, because in kickboard 5 and sump 4
Side wall palette, kickboard 5 are not in there be not the case where upstream face, and measuring instrument weight is not too much heavy, therefore are not in flat
Weighing, 2 gravity of platform is overweight to cause sump 4 or kickboard 5 the case where crack occur, while the weight of balancer 2 makes the water surface will not be always
Fluctuation, to ensure that the steady of kickboard 5, as long as measuring instrument is fixedly mounted on balancer, 2 center makes its center of gravity same
It is centrally located, that is, can guarantee that balancer 2 balances always under the action of kickboard 5, it should be noted that, because balancer 2 and bottom plate 1 it
Between distance it is little, therefore the angle that the balancer 2 can be swung is also limited, survey crew need to first be about to the adjustment of bottom plate 1 compared with
To be smooth, this is easy to operate and realize for survey crew, and most of measurement environment can't also exist
Very big tilt angle.
Embodiment two, on the basis of example 1, the sump 4 are annular, and outboard sidewalls are the one of spherical shape
Part, the kickboard 5 is annular, the kickboard 5 and 4 inner sidewall of the sump connection in sealing contact, specifically, described
A part of the equal homocentric sphere of 4 outboard sidewalls of sump, 4 inner sidewall palette of the kickboard 5 and sump, so that the kickboard
5 can move close to its inner wall in all directions in sump 4, so that no matter bottom plate 1 is askew to which direction with which kind of angle
Tiltedly, kickboard 5 can keep horizontal with the water surface, and will not be limited by sump 4 and 5 shape of kickboard causes bottom plate 1 to tilt to some angle
Kickboard 5 is restricted the level of cannot keep when degree or position, meanwhile, kickboard 5 and 4 inner sidewall palette of sump are but also kickboard 5
Under water do not overflow to the top of kickboard 5, to ensure that the stabilization of water in sump 4, meanwhile, encapsulation process is but also kickboard
5 can bear more weight, constitute enclosed construction, Gu Shui because of the sump 4 of sealing and with the kickboard 5 of 4 palette of sump
Face can carry heavier weight, until kickboard 5 or 4 side wall of sump are cracked, 6 upper end of support column is hemispherical, on
End is that hemispheric support column 6 rotates balancer 2 anyway, and support column 6 can be connected and be supported with balancer 2
Balancer 2, hemispheric setting is so that balancer 2 will not cause 2 somewhere of balancer to tilt because of the corner angle occurred on support column 6.
Embodiment three is further ensured that the level of balancer 2 on the basis of example 1, improves the stabilization of the present apparatus
Property, the present embodiment provides a kind of specific structures, are realized with auxiliary floating plate 5 and support column 6 to the horizontally-supported of balancer 2, tool
Body, the balancing device further includes several hydraulic pressure support cylinders 7 being fixedly connected on bottom plate 1, each hydraulic branch
Support cylinder 7 is cylinder that hollow tip offers through-hole, slided up and down in each hydraulic pressure support cylinder 7 be connected with it is hydraulic
Support rod 8, each 8 upper end of hydraulic pressure support bar are connected with 2 lower end surface of balancer, each liquid
Pressure 8 upper end of support rod is hemispherical, and upper end is that hemispheric hydraulic pressure support bar 8 rotates balancer 2 anyway, hydraulic
Support rod 8 can connect with balancer 2 and support balancer 2, hemispheric to be arranged so that balancer 2 be because of hydraulic branch
The corner angle occurred on strut 8 cause 2 somewhere of balancer to tilt, and each hydraulic pressure support cylinder 7 connects with the sump 4
It is logical, interconnected between each hydraulic pressure support cylinder 7, be fixedly connected on the bottom plate 1 with it is hydraulic described in one
The booster pump 9 that support tube 7 is connected to, herein because the present apparatus is relatively small and needed for offer pressure it is equally little, therefore institute
The booster pump 9 stated should also use the booster pump of lesser volume and specification, and the booster pump of JT-660A-24 specification can be used,
Other booster pumps 9 up to specification, the booster pump 9 and the storage for being fixedly connected on 1 lower end of bottom plate can also be used
Battery electrical connection, the effect of the booster pump 9 are to provide pressure for several hydraulic pressure support bars 8, to keep
Its support to balancer 2 passes through between several hydraulic pressure support cylinders 7, between several hydraulic pressure support cylinders 7 and sump 4
Pipeline interconnects, under the space of sump 4 and 5 lower end of kickboard composition, each hydraulic pressure support cylinder 7 and corresponding hydraulic pressure support bar 8
It holds and interconnects the flow promoter system to form a connection between the space and each pipeline of composition, when bottom plate 1 is horizontal, the system
In be full of water, when the skew of bottom plate 1, according to law of connected vessels, the water surface in the system remains horizontal and in same water
Plane realizes that, to the horizontally-supported always of balancer 2, the booster pump 9 provides water flow pressure for whole system with this,
Preferably to keep the level of balancer 2.
