Description
Technical Field
The utility model relates to a grade rod technical field specifically is a grade rod for road engineering.
Background
The slope rule is a kind of graphic curve rule for determining the corresponding ground slope or its inverse process according to the parallel distance of the contour lines on the topographic map. Road construction manages and uses grade rod, is mainly used for measuring urban road's slope size, through the slope measurement to urban road, can carry out reasonable protection and safety guarantee to urban road. For example, the document with the Chinese patent publication number of CN 211373591U discloses a road slope ruler for engineering supervision, and solves the problems that in the prior art, the slope ruler is not easy to perform slope measurement on the slope of the road at the upper right of the oblique direction in the using process, and the straight ruler and the slope protractor are fixedly installed and not easy to detach, so that inconvenience is brought to carrying and placing of the straight ruler and the slope protractor. However, when the device is used, only short-distance gradient detection is available, and long-distance gradient detection is not available.
SUMMERY OF THE UTILITY MODEL
The utility model mainly provides a slope chi for road engineering solves the problem that prior art can't detect the slope of longer distance.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a grade rod for road engineering, includes the first mounting plate and the second mounting plate of isostructure, first mounting plate and second mounting plate all are provided with the leveling footstand that is used for the leveling mounting plate to and be used for observing the horizontal mechanism of level situation, still be provided with the installation pole perpendicularly on first mounting plate and the second mounting plate, be provided with laser emitter through angle adjusting part on the installation pole of first mounting plate, be provided with the laser receiver plate on the installation pole of second support, be provided with the location sign on the laser receiver plate. Wherein, angle adjusting part can adopt prior art as long as can realize its theory of operation can, mainly used connects installation pole and laser emitter to measure installation pole and laser emitter's angle. Because first support and second support level, the contained angle of laser emitter and erection column plus the slope contained angle equals 90, both can calculate the slope angle. The laser horizontal emission of the laser emitter and the middle part of the positioning mark are on the same plane by horizontal placement. During the use, install first support and second support respectively at the both ends of the long distance slope that awaits measuring to cooperation horizontal mechanism is with first support and second support adjustment level, guarantees the straightness that hangs down of installation pole and corresponding equipment. After the installation, through the location sign of angle adjustment subassembly adjustment laser emitter alignment laser receiver board, two erection columns like this, ground and laser emitter constitute parallelogram, then angle adjustment subassembly measures the angle to obtain the slope, overall structure is simple, the practicality of being convenient for.
Furthermore, jacks are arranged on the first support plate and the second support plate, and the mounting rod is inserted into the jacks. Thus, the installation structure is simple.
Furthermore, an internal thread is further arranged in the jack, and an external thread is arranged at the lower end of the mounting rod. And the connection is more stable by adopting the threaded connection.
Further, the horizontal mechanism adopts horizontal beads. The cost of using horizontal beads is low.
Further, leveling foot stool include with first mounting panel and second mounting panel threaded connection's threaded rod to and ball pin joint in the support of threaded rod bottom. When the support is used, the height of the threaded rod on the first support plate and the second support plate can be controlled by rotating the threaded rod, and the threaded mode is stable in connection, simple in structure and accurate in rotation; the base ball pin connection does not affect the placement.
Has the advantages that: during the use, install first support and second support respectively at the both ends of the long distance slope that awaits measuring to cooperation horizontal mechanism is with first support and second support adjustment level, guarantees the straightness that hangs down of installation pole and corresponding equipment. After the installation, through the location sign of angle adjustment subassembly adjustment laser emitter alignment laser receiver board, two erection columns like this, ground and laser emitter constitute parallelogram, then angle adjustment subassembly measures the angle to obtain the slope, overall structure is simple, the practicality of being convenient for.
