Detailed Description

Example 1: a pavement protection board, as shown in fig. 1 and fig. 2, comprises a plurality of protection board bodies 2 which are spliced with each other, and a fixing mechanism 3 which is arranged between the adjacent protection board bodies 2.

As shown in fig. 2 and 3, the fixing mechanism 3 includes a plurality of engaging teeth 31 fixedly connected to an edge of the protection plate body 2, a groove 21 formed on a side of the protection plate body 2 away from the engaging teeth 31 and engaged with the engaging teeth 31 of the adjacent protection plate body 2, and a flush component 32 disposed in each engaging tooth 31 and used for keeping flush with the adjacent protection plate body 2. The engaging teeth 31 are uniformly arranged along the edge of the protection plate body 2, and the thickness of the engaging teeth 31 is smaller than that of the protection plate body 2. The cross section of the meshing teeth 31 is trapezoidal, and the upper bottom surfaces of the meshing teeth 31 are fixedly connected with the edge of the protection plate body 2. When two adjacent protection shield bodies 2 splice each other, make interlock tooth 31 card in the recess 21 of adjacent protection shield body 2, realized splicing each other of two adjacent protection shield bodies 2.

As shown in fig. 2 and 3, due to the uneven road surface, a gap is left between the road surface and the protection plate body 2, when a vehicle is pressed on the upper surface of the protection plate body 2, the protection plate body 2 is easily bent elastically in the longitudinal direction, and two adjacent protection plate bodies 2 are easily separated, so that the arrangement of the flush component 32 reduces the occurrence of such a situation. A slide way 22 is horizontally arranged on one side of each meshing tooth 31, which is far away from the end face fixedly connected with the protection plate body 2, towards the protection plate body 2, the slide way 22 is simultaneously penetrated in the meshing teeth 31 and the protection plate body 2, and the axis of the slide way 22 is vertical to the end face of the meshing tooth 31; the upper surface of the joint of the protection plate body 2 and the meshing teeth 31 is provided with a plurality of strip grooves 23 communicated with each slide way 22, and the strip grooves 23 are distributed along the length direction of the slide ways 22. The upper surface of the protection plate body 2 is provided with a lower groove 26 along the edge fixed with the meshing teeth 31, and the bottom surface of the lower groove 26 is flush with the upper surface of the meshing teeth 31.

As shown in fig. 3, the flush component 32 includes a sliding block 321 disposed in the sliding way 22 and slidably connected to an inner wall of the sliding way 22, and a limit block 322 disposed in the bar groove 23 and fixedly connected to the sliding block 321 for controlling the sliding block 321. The upper surface of the limiting block 322 is lower than the upper surface of the lower groove 26, so that the rolling of the vehicle on the limiting block 322 is reduced, the automobile tire is protected, and the limiting block 322 is also protected. A fixing hole 211 for accommodating the sliding block 321 is formed on the bottom wall of each groove 21 at a position corresponding to the port of the slide 22.

As shown in fig. 4 and 5, after the two adjacent protection plate bodies 2 are spliced by the worker, a moving assembly 4 for driving a limit block 322 to insert a sliding block 321 into a fixing hole 211 is disposed above the protection plate bodies 2. The moving assembly 4 includes a handle 41 for grasping and a lever 42 secured to an end of the handle 41. The upper surface of the stopper 322 is formed with a moving hole 323 into which the lever 42 is inserted. The staff can insert into the removal hole 323 the control lever 42, drives the stopper 322 through the handle 41 and slides in the strip groove 23 to make the slider 322 insert into the fixed orifices 211, and then make two adjacent protection plate bodies 2 connect more stably.

As shown in fig. 4, in order to facilitate the insertion of the slider 321 into the fixing hole 211, one end of the slider 321 away from the protection plate body 2 is provided with a chamfer, and when the slider 321 is inserted into the fixing hole 211, the end with the chamfer firstly extends into the fixing hole 211, so that the accuracy of inserting the slider 321 into the fixing hole 211 is improved.

As shown in fig. 2 and 3, a cover plate 24 for protecting the fixing mechanism 3 is further disposed on the upper surface of the lower groove 26, and one end of the cover plate 24 is rotatably connected to the protection plate body 2. After splicing two adjacent protection plate bodies 2, the worker rotates the cover plate 24 to cover the cover plate 24 above the fixing mechanism 3, and the upper surface of the cover plate 24 is flush with the upper surface of the protection plate body 2. The strip groove 23 and the moving hole 323 are covered by the cover plate 24, so that dust is prevented from entering, the moving operation of the moving assembly 4 on the limiting block 322 is guaranteed, and the normal work of the flushing assembly 32 is improved. Because the upper surface of the cover plate 24 is flush with the upper surface of the protection plate body 2, the stability of the vehicle above the protection plate body 2 is guaranteed.

The working process is as follows:

when laying the protection plate body 2, firstly, one protection plate body 2 is horizontally placed, and the edge with the meshing teeth 31 is vertical to the laying direction. The groove 21 of the other protection plate body 2 is clamped into the meshing teeth 31, the two protection plate bodies 2 are mutually spliced, the sliding block 321 is scratched into the fixing hole 211 in the groove 21 by using the moving assembly 4, namely, the two protection plate bodies 2 are fixed, and the cover plate 24 is turned over to cover the joint of the two protection plate bodies 2. And the protection of the road surface can be realized by sequentially installing the rest protection plate bodies 2 in the same way.
