Description
Technical field
The utility model belongs to a kind of laser level rule for measuring section of jurisdiction posture.
Background technique
In metro shield tunneling process, in order to ensure section of jurisdiction position is accurate, need to carry out real-time monitoring to section of jurisdiction posture.
All it is to be examined qualified section of jurisdiction due to carrying out assembled section of jurisdiction, usually assumes that assembled good section of jurisdiction is a proper circle, by complete
Instrument of standing surveys the foundation of the centre coordinate and elevation of section of jurisdiction as section of jurisdiction position control, and horizontal ruler is placed on to the inverted arch of section of jurisdiction
On, level(l)ing bubble is in center condition, by measuring horizontal ruler midpoint elevation, just can determine that design posture and practical posture
Between deviation.But traditional horizontal ruler is too long, at least needs 2 people to assist in measurement process.Such horizontal ruler is taken
Band, using very inconvenient and waste of manpower, while measurement accuracy is also inaccurate, cause measurement to be difficult to get a desired effect,
Cause integral construction error big, to influence entire construction speed.
Summary of the invention
The purpose of this utility model is to design a kind of laser level rule for measuring section of jurisdiction posture, can improve the survey of section of jurisdiction posture
Accuracy of measurement has structure simple, small in size, compact and reasonable, carries easy to use, precisely stablizes and measures time saving and energy saving excellent
Point.
For this reason, the utility model is made of horizontal ruler.The rectangular in cross-section of horizontal ruler, the arranged on left and right sides end of horizontal ruler
It is interior to be equipped with slot, spiral shell is distinguished on horizontal ruler corresponding with slot front and rear sides face is equipped with adjusting bolt, the adjusting in slot
The front end of bolt connects with axis in the middle part of the rear end face of corresponding fixed plate respectively, and the laser with display screen is fixed in slot two solid
It is interior in the middle part of the upper surface of horizontal ruler to be equipped with balance plate level pipe between fixed board, it is equipped with card slot in the middle part of the front end face of horizontal ruler, is blocked
Non-prism piece is equipped in slot.
It is equipped with switching hook bolt mouth in the middle part of the lower end surface of the horizontal ruler, bracket switching is connected in hook bolt mouth of transferring
Head.Horizontal line is equipped in the middle part of the forward and backward end face outside of the horizontal ruler.The center of the non-prism piece with display screen
Laser light-emitting window and main scale on horizontal central axis be overlapped.
Above structure has reached the purpose of this utility model.
The utility model can improve the measurement accuracy of section of jurisdiction posture, have structure simple, and small in size, compact and reasonable carries
It is easy to use, precisely stablize and measure time saving and energy saving advantage.It has the advantage that as follows:
1, the long 30cm of the horizontal ruler of the utility model, it is small in size, only a people is needed to use horizontal ruler in measurement process, compared
Traditional horizontal ruler can save manpower, when not used detachably, easy to carry.
2, laser of the utility model with display screen cooperates engineering survey centering rod, can survey the shield of all radiuses
The accuracy of measurement is greatly improved in tunnel duct piece posture.
3, the utility model design is unique, structure is simple, compact and reasonable, reliable working performance, flexible operation are laborsaving, has
It is suitable for construction usage, convenient for popularization and use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A the schematic diagram of the section structure of Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, a kind of laser level rule measuring section of jurisdiction posture is made of horizontal ruler 2.
The rectangular in cross-section of horizontal ruler, the length of horizontal ruler are 30cm, are equipped with slot in the arranged on left and right sides end of horizontal ruler
11.Spiral shell is distinguished on horizontal ruler corresponding with slot front and rear sides face is equipped with adjusting bolt 6, the adjusting bolt in slot
Front end connects with axis in the middle part of the rear end face of corresponding fixed plate 5 respectively, and the laser 1 with display screen is fixed on two fixed plates in slot
Between, two fixed plates can be driven to relatively move the laser with display screen that is fixedly clamped by turning two adjusting bolts, or drive
Two fixed plates move front-rear position of laser of the adjustment with display screen in slot in the same direction.Laser with display screen is market
Upper purchased product.
Balance plate level pipe 3 is equipped in the middle part of the upper surface of horizontal ruler.Card slot 10 is equipped in the middle part of the front end face of horizontal ruler,
Non-prism piece 9 is equipped in card slot, non-prism piece selects that is sold in the market to come card non-prism piece.
It is equipped with switching hook bolt mouth 8 in the middle part of the lower end surface of the horizontal ruler, is connected with bracket in hook bolt mouth of transferring and turns
Connector 7 connect horizontal ruler with engineering survey centering rod by bracket adapter to facilitate.
Horizontal line 4 is equipped in the middle part of the forward and backward end face outside of the horizontal ruler, to facilitate the horizontal position of calibrated horizontal ruler
It sets.Horizontal central axis weight on the center of the non-prism piece and the light-emitting window and main scale of the laser with display screen
It closes.
When measurement, first the laser with display screen and non-prism piece are separately mounted in the slot and card slot of horizontal ruler.
Pay attention to making in installation process in horizontal on the center of non-prism piece and the light-emitting window and main scale of the laser with display screen
Mandrel line weight.The adjusting bolt tightened in fixed plate fixes the laser with display screen, and guarantees that laser is horizontal.By bracket
Adapter is tightened on switching hook bolt mouth, and horizontal ruler is mounted on engineering survey centering rod by bracket adapter.It opens
Laser with display screen, the laser irradiation section of jurisdiction issued show measured distance parameter.Travel engineering measurement centering rod makes water
The laser reading at leveling ruler both ends is equal, and main scale balances air level pipe level, then reads upright project measurement centering rod again
Scale just can determine that the deviation between Segment design posture and practical posture by acquisition non-prism piece centre coordinate and elevation.
Construction personnel's later period is facilitated to be adjusted section of jurisdiction position.
In short, the utility model can improve the measurement accuracy of section of jurisdiction posture, have structure simple, small in size, compact conjunction
Reason, carrying is easy to use, precisely stablizes and measure time saving and energy saving advantage.
