[0002] With the advancement of urbanization, urban roads are interconnected. During the long-term use of roads, long-term pressure and temperature changes on the roads are prone to cause road cracks of varying sizes. Once cracks occur, they have an adverse effect on traffic smoothness, traffic noise and pedestrian driving safety. Road cracks need to be repaired. For smaller road cracks, only homogeneous materials need to be used to fill them. For larger road cracks, splicing equipment is needed to fill the roads to ensure smooth use of the roads. Splicing plates are placed in larger road cracks to fill them, and rods are used to fix both sides of the cracks to achieve the effect of inhibiting the expansion of the cracks. However, since the roads are still in use, the cracks continue to expand in varying sizes, and the adaptation effect of the splicing plates is poor.

DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 This embodiment provides a pavement crack suppression splicing device, including: a splicing plate 1, a connecting piece 2, a stabilizing frame 3, an insert rod 4, a supporting frame 5 and an elastic block 6.
[0022] The lower sides of the left and right parts of the front and rear parts of the splicing plate 1 are connected with the connecting parts 2, the upper part of the splicing plate 1 is connected with a plurality of anti-slip strips, the lower part of the connecting parts 2 is connected with the stabilizing frame 3, a part of the lower part of the stabilizing frame 3 is slidably connected with the plug rod 4 for inserting into the surrounding roadbed for fixing and inhibiting the expansion of cracks, the stabilizing frame 3 and the adjacent plug rods 4 form a stable triangular structure with strong stability, the outside of the plug rods 4 are connected with the boosting blocks, the lower side of the splicing plate 1 is connected with three supporting frames 5 for supporting the splicing plate 1, and a plurality of elastic blocks 6 for buffering the splicing plate 1 are connected between the supporting frame 5 and the splicing plate 1.
[0023] Furthermore, it also includes the extension mechanism 7, which includes the extension plate 71, the telescopic rod 72 and the first spring 73. The left and right parts of the splicing plate 1 are slidably connected with the extension plate 71 for extension support, and 5 telescopic rods 72 are connected between the lower part of the extension plate 71 and the side adjacent to the splicing plate 1, and the first spring 73 is connected between the lower part of the extension plate 71 and the splicing plate 1 near the telescopic rod 72.
[0024] When splicing road cracks, the present device can be used. It should be noted that, first, the cracking position of the large road crack is trimmed, so that the road crack is in a rectangular structure. At the same time, four mounting holes are opened on both sides of the road, and then the splicing plate 1 is placed in the road crack. At the same time, the insertion rods 4 are inserted into the mounting holes for clamping and fixing. When the width of the road crack is larger than the width of the splicing plate 1, the first spring 73 drives the extension plate 71 to slide outward and open, so that the extension plate 71 drives the adjacent five telescopic rods 72 to telescope and extend outward, so that the extension plate 71 is all connected to the splicing. The plate 1 supports the blind area to fill in. After the splicing plate 1 is put into use, when pedestrians or cars on the road press the splicing plate 1, the support frame 5 supports the splicing plate 1, and the elastic block 6 buffers the splicing plate 1 after being subjected to force. When the road crack continues to expand, the first spring 73 continues to drive the adjacent extension plate 71 to slide outward and open, so as to extend and support the expanding road surface. In summary, through the cooperation between the extension plate 71 and the first spring 73, the support position of the splicing plate 1 is extended and expanded, thereby reducing the occurrence of gaps in road cracks and improving the adaptability of road support.
[0025] like Figure 1 and Figure 4 As shown, it also includes a limiting mechanism 8, which includes the fixed ring 81, the sliding ring 82, the second spring 83 and the elastic rod 84. A part of the insertion rod 4 is connected to the fixed ring 81, and the middle part of the insertion rod 4 is slidably connected to the sliding ring 82. The second spring 83 is connected between the fixed ring 81 and the adjacent sliding ring 82. Six elastic rods 84 for supporting the push installation position are connected between the edges of the fixed ring 81 and the adjacent edges of the sliding ring 82. The middle part of the elastic rod 84 is provided with a hollow groove to enhance the deformation ability of the elastic rod 84.
[0026] It should be noted that when the insertion rod 4 is used to engage with the mounting hole, the mounting hole is slightly expanded so that the insertion rod 4 drives the adjacent multiple elastic rods 84 to be inserted into the mounting hole. At the same time, the sliding ring 82 drives the adjacent elastic rods 84 to slide inward. At this time, the second spring 83 is stretched under force, so that the second spring 83 drives the adjacent sliding ring 82 to slide toward the adjacent fixed ring 81. The elastic rods 84 can push and support the inner wall of the mounting hole, thereby enhancing the fixing effect of the insertion rod 4. In summary, the sliding ring 82 cooperates with the elastic rod 84 to push and support the mounting hole, thereby enhancing the fixing strength of the insertion rod 4.
[0027] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
