Reliability.
Utility model content
The utility model is intended to provide a kind of box beam bridge sensor levelling device, for being optimized to the prior art.It should
Device is easy for installation, easy to operate, accurate data.
What the utility model adopts the following technical solution to realize：
A kind of box beam bridge sensor levelling device including connecting screw, rotary screw, the first fixed plate, is fixed with first
The second fixed plate that plate one side is arranged in parallel and the backing plate for being arranged on the first fixed plate another side bottom；Wherein,
One end of connecting screw is fixed in the horizontal direction on the first fixed plate one side, and the second fixed plate is sleeved on this
On the other end of connecting screw, one end of rotary screw is fixed in the horizontal direction on the first fixed plate another side, another
It holds as free end, backing plate is sleeved on rotary screw, and several foot screws are provided on backing plate.
The utility model, which further improves, to be, the quantity of connecting screw is two.
The utility model, which further improves, to be, further includes the first fixing nut being threadedly coupled with connecting screw.
The utility model, which further improves, to be, further includes the second fixing nut being threadedly coupled with rotary screw.
The utility model, which further improves, to be, the quantity of foot screw is three, and is located at three of triangle respectively
On vertex.
The utility model, which further improves, to be, is offered on the first fixed plate and the opposite side of the second fixed plate
Rough surface groove.
The utility model, which further improves, to be, during use state, which, which passes through the first fixed plate and second, fixes
Plate is clamped on bridge subsection, and sensor is mounted on foot screw, and top is provided with level(l)ing bubble, and foot screw bottom is placed on
On backing plate, backing plate can be adjusted in rotary screw in rotation angle.
The utility model has following beneficial technique effect：
The utility model is connected by two fixed plates using screw rod, then is fixed with fixing nut, is clamped in bridge subsection and is reached
Sensor is connected with to fixing device purpose, and wherein on a piece of backing plate.It is set simultaneously there are one level(l)ing bubble, led on a sensor
Crossing revolving joint is generally horizontal sensor, then fixes sensor by fixing nut, finally adjusts again
Foot screw below whole sensor reaches elaborate position.
Compared with existing equipment, the utility model has following a few place's advantages：
1st, it is easily installed and dismantles；2nd, installation site can be selected flexibly；3rd, in the basic leveling of sensor (foot screw is not adjusted
Before) segment can be detected whether in perpendicular；4th, it can be used repeatedly；5th, measurement accuracy is improved.
Description of the drawings
Fig. 1 is a kind of structure diagram of box beam bridge sensor levelling device of the utility model.
Fig. 2 is a kind of installation effect side view of box beam bridge sensor levelling device of the utility model.
In figure：1- connecting screws, the first fixed plates of 2-, 3- foot screws, the first fixing nuts of 4-, 5- level(l)ing bubbles, 6- are passed
Sensor, 7- rotary screws, 8- backing plates, 9- bridge subsections, the second fixed plates of 10-, the second fixing nuts of 11-.
Specific embodiment
The utility model is made further instructions below in conjunction with attached drawing.
As depicted in figs. 1 and 2, a kind of box beam bridge sensor levelling device of the utility model, is made of two parts：Fixed dress
It puts and tumbler.Device is clamped on bridge subsection 9 by 1 and first fixing bolt 4 of connecting screw, wherein, fixed dress
It puts including the first fixed plate 2 and the second fixed plate 10, and is connected from connecting screw 1 and (if vertical bridge is longer to length, can also increase more
Several connecting screws), the distance between the first fixed plate 2 and the second fixed plate 10 can according to the width adjusting in bridge section,
There is rough surface groove in its inside.Tumbler makes 6 basic leveling of sensor by being rotated in perpendicular around rotary screw 7,
Then fixation is tightened with the second fixing nut 11, finely tuning the foot screw 3 on backing plate 8 makes level(l)ing bubble 5 placed in the middle, finally, realizes and passes
Sensor leveling.
The utility model adjusts the distance between two panels fixed plate by connecting screw 1, and tightens the first fixing bolt 4 and incite somebody to action
Device is clamped on bridge subsection 9, revolving joint, by 6 coarse adjustment of sensor to horizontal position, then fixes spiral shell by second
Mother 11 tightens fixation, and finally finely tuning foot screw 3 makes level(l)ing bubble 5 placed in the middle.
