[0030] Embodiment

[0031] As Figure 1 shown, a pavement expansion joint device proposed by the present utility model includes a first installation steel 1 and a second installation steel 2. A convex strip 16 is provided at one end of the first installation steel 1 close to the second installation steel 2, and a recess 20 matching the convex strip 16 is provided at one end of the second installation steel 2 close to the first installation steel 1, so that the convex strip 16 is inserted into the recess 20 to facilitate the connection and support of the first installation steel 1 and the second installation steel 2;

[0032] In addition, a guiding strip 17 is installed on the outer surface of the convex strip 16, and a guiding seat 21 is installed on the outer surface of the recess 20, so that the guiding strip 17 can be inserted into the guiding seat 21 to provide guiding support for the expansion joint device.

[0033] As Figure 1 shown in FIG. -3, the device further includes a receiving groove 3 opened on the inner walls of the first installation steel 1 and the second installation steel 2. A buffer plate 4 is arranged in the receiving groove 3. A plurality of guiding grooves 15 are equidistantly opened on the inner wall of the receiving groove 3. Guiding plates 14 matching the guiding grooves 15 are installed on both sides of the buffer plate 4. By using the guiding plates 14 to be stuck into the guiding grooves 15, when the expansion joint expands and contracts, the guiding plates 14 slide along the guiding grooves 15 to play a role of limiting and protecting;

[0034] It is worth noting that a rubber block 19 is arranged between the first installation steel 1 and the second installation steel 2. An elastic member 18 is connected to the rubber block 19. The elastic member 18 cooperates with the buffer plate 4, so that the expansion joint structure can form multiple layers of protection and make the protection effect better.

[0035] As Figure 3 shown, the device further includes a protection covering device. The protection covering device is arranged on the buffer plate 4 to prevent sundries and stones on the road surface from entering the expansion joint. The protection covering device includes a support belt 5 installed on the top of the buffer plate 4. The support belt 5 includes an arc-shaped support plate 51 and a communicating arc channel 52. The communicating arc channel 52 and the arc-shaped support plate 51 are fixedly connected and respectively abut against the inner walls of the first installation steel 1 and the second installation steel 2. The arc-shaped support plate 51 is fixedly connected to the top of the buffer plate 4;

[0036] Particularly importantly, the arc-shaped arrangement of the connecting arc channel 52 in cooperation with the connection of the arc-shaped support plate 51 can make it easy for the retained gravel, sundries, leaves, etc. to accumulate on the arc of the connecting arc channel 52, facilitating subsequent cleaning work.

[0037] As Figure 1 As shown in FIG. -4, the device further includes an auxiliary mechanism, which is arranged on the protective covering device for assisting in cleaning the retained sundries and stones. The auxiliary mechanism includes a fixed box 6 fixedly installed on the top of the arc-shaped support plate 51. A chute 8 is arranged in the fixed box 6, and a slider 9 is slidably installed in the chute 8. The top of the slider 9 is fixedly connected with a support rod 10. The height of the support rod 10 is higher than that of the fixed box 6. The support rod 10 moves back and forth under the drive of the slider 9;

[0038] Furthermore, a notch 7 for the movement of the support rod 10 is opened on the fixed box 6. A sealing strip is arranged between the inner wall of the notch 7 and the support rod 10. The sliding of the slider 9 can drive the support rod 10 to move back and forth along the notch 7. The sealing strip can prevent gravel and sundries from entering the fixed box 6 and affecting the sliding of the slider 9;

[0039] Even further, connecting rods 12 are fixedly installed on both sides of the support rod 10. A scraper 13 slidably connected with the connecting arc channel 52 is installed on the connecting rods 12. The top of the support rod 10 is fixedly connected with a pull ring 11. Pulling the pull ring 11 makes the slider 9 drive the support rod 10 to move back and forth. Under the action of the connecting rods 12, the scraper 13 can scrape back and forth the gravel, sundries, etc. accumulated on the connecting arc channel 52, facilitating the cleaning work and saving labor.

[0040] Working principle: By using the cooperation of the guiding plate 14 and the guiding groove 15, when the expansion joint expands and contracts, the guiding plate 14 drives the buffer plate 4 to slide in the guiding groove 15. In cooperation with the connection and installation of the arc-shaped support plate 51 and the connecting arc channel 52, it can prevent gravel, sundries, leaves, etc. from falling into and getting stuck inside the expansion joint device, affecting the expansion and contraction performance of the expansion joint. And under the arc dimension of the connecting arc channel 52, sundries are easily accumulated and retained on the connecting arc channel 52. By pulling the pull ring 11 to move the slider 9, the movement of the slider 9 drives the movement of the support rod 10, so that the connecting rod 12 drives the scraper 13 to scrape back and forth to push and clean the gravel, sundries, etc. accumulated on the connecting arc channel 52, facilitating the cleaning work on the top, saving the labor of the cleaners, and avoiding affecting the normal operation of vehicles on the road surface.

[0041] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
