Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 4, a municipal works road roughness measuring device, including

automobile body

1, 1 both ends of automobile body are equipped with

running wheel mechanism

2, 1 lower extreme of automobile body is equipped with measuring

wheel

3, and 1 upper end of automobile body is equipped with and is used for the record and show measuring data microcomputer 4, and 3 front ends of measuring wheel are equipped with two hollow baffles 5, and two hollow baffles 5 make up and form V type structure and be fixed in 1 lower extreme of automobile body, the hollow baffle 5 bottom is open, and hollow baffle 5 lateral part has been seted up the air outlet and has been connected with exhaust column 6 one end, and the exhaust column 6 other end is connected with air exhauster 7 one end. In this embodiment, two hollow baffles 5 are combined to form a V-shaped structure, so that when sundries (such as branches or stones) appear on the road, the hollow baffles 5 can effectively block and push away the sundries to both sides, and the measuring wheel is prevented from being collided to influence the measuring process. In addition, when the exhaust fan 7 works, negative pressure is generated in the hollow baffle 5, so that light sundries such as small-particle soil or paper scraps on the road surface can be sucked into the hollow baffle 5 and then discharged through the exhaust pipe 6 and the exhaust fan 7.

Preferably, 8 one ends of rotary rod are located in the measuring wheel 3 is articulated, the 8 other ends of rotary rod and the perpendicular fixed connection of 9 one ends of rotation axis, and on spur gear 10 center was fixed in rotation axis 9, the 9 other ends of rotation axis passed through the bearing and was connected with mounting panel 20, and mounting panel 20 is fixed in 1 lower extreme of automobile body, the spur gear 10 meshed with the spur rack 11.1 of 11 bottoms of carriage release lever, 11 vertical settings of carriage release lever and with 1 sliding fit of automobile body, 11 lateral parts of carriage release lever are equipped with laser range finder 12, laser range finder 12 passes through the signal line and is connected with microcomputer 4. In this embodiment, on level and smooth road surface, measuring wheel 3 hugs closely the road surface because its dead weight, when meetting unevenness's road surface, measuring wheel 3 can be downward or rebound, thereby can drive rotary rod 8 and take place rotatoryly, and then make rotary shaft 9 take place to rotate, finally make spur gear 10 take place rotatoryly, spur rack 11.1 rather than the meshing also can reciprocate like this, thereby shift lever 11 also reciprocates thereupon, laser range finder 12 just can take place the upper and lower displacement like this, laser range finder 12 can be with the displacement data transfer who produces to microcomputer 4, then produce corresponding roughness report through microcomputer 4 analysis.

Preferably, the rotating rod 8 is connected with the bottom of the compression spring 13, and the top of the compression spring 13 is fixedly connected with the lower end of the vehicle body 1. In order to prevent the measuring wheel 3 from jumping too much, after the compression spring 13 is arranged, the measuring wheel 3 can be further clung to the road surface, and the accuracy of the measuring result is ensured.

Preferably, the upper part of the compression spring 13 is sleeved with a limiting sleeve 14, and the limiting sleeve 14 is fixed at the lower end of the vehicle body 1. The limiting sleeve 14 can limit the extension direction of the compression spring 13, and the stability of the extension direction is ensured.

Preferably, the upper portion of the moving rod 11 is sleeved with a linear sliding bearing 15, and the linear sliding bearing 15 is fixed on the vehicle body 1 in a penetrating way. The linear sliding bearing 15 makes the up-and-down movement of the moving bar 11 smoother and smoother.

Preferably, a horizontal plate 16 is arranged on the side of the moving rod 11, a laser range finder 12 is fixed on the horizontal plate 16, a baffle 17 is arranged right above the laser range finder 12, and the baffle 17 is fixed at the lower end of the vehicle body 1.
