Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a main beam 1, auxiliary beams 2 capable of extending are arranged on the left and right sides of the main beam 1, and supporting wheels 3 are arranged on the middle part of the main beam 1 and the auxiliary beams 2 on the left and right sides, wherein the wheels of the main beam 1 can move up and down; a vertical supporting rod 4 is fixed above the main beam 1, a main shaft 5 in the front-back direction is installed at the upper end of the supporting rod 4, a balancing rod 6 is installed at the rear end of the main shaft 5, and a pointer 8 is fixed at the front end of the main shaft 5; the supporting rod 4 is fixed with a protractor 9, and the circle center of the protractor 9 is coincided with the axis of the main shaft 5.
In order to realize the extension and retraction of the secondary beam 2, guide rods are fixed at two ends of the main beam 1, and blind holes are formed in the secondary beam 2. The guide rod can be inserted into the blind hole, and the auxiliary beam 2 is provided with a compression screw.
For realizing the support, the supporting wheels 3 consist of wheels and wheel forks, wherein each secondary beam 2 is provided with a front supporting wheel 3 and a rear supporting wheel 3; a vertical rod penetrates through the middle of a wheel fork of the supporting wheel 3 arranged on the main beam 1, the upper end of the vertical rod is fixed on the main beam 1, and a pressure spring is sleeved on the vertical rod.
For better balance, the left end and the right end of the balancing rod 6 are provided with the same balancing weights 7.
When the utility model is used, firstly, because each auxiliary beam 2 is provided with the front and the back supporting wheels 3, the four wheels of the left and the right auxiliary beams 2 can play the role of supporting the whole device; the support wheels 3 in the middle of the main beam 1 can move up and down, so that the support wheels do not play a supporting role, but play a guiding role.
When the auxiliary beam is used specifically, the auxiliary beam 2 is firstly pulled out to two sides in equal length, and the supporting wheels 3 of the auxiliary beam 2 correspond to the solid lines on the two sides of the road; the supporting wheels 3 of the main beam 1 correspond to the most middle lane line of the road; this ensures that the orientation of the entire main beam 1 is accurate. The measured height points of the ramp are ensured to be in the same measuring plane. There is no major error.
Referring to fig. 2, since the ramp is inclined, the whole main beam 1 is in the same inclined state as the ramp, however, the balance bar 6 on the main beam 1 is in a horizontal state, and therefore the pointer 8 which is synchronous with the balance bar 6 is also in a horizontal state, so that the inclination angle of the ramp can be calculated by reading the angle indication of the pointer 8 on the protractor 9; it is simple and quick.
And when different positions need to be measured, the slope gradient of each position can be read in real time only by pushing the whole device to walk along the lane line on the road, so that the later data can be conveniently sorted.
