[0002] In order to prevent the cement pavement from being damaged by thermal expansion and contraction, some transverse shrinkage joints are reserved in the middle of the cement pavement when new cement concrete roads are built. Then, foam strips are pressed into the joints to control the injection of sealant, keep the depth uniform, and provide a long-lasting waterproof effect. However, after long-term rolling by vehicles, the cement pavement will crack or be damaged from the joints, which must be taken seriously. A connection device needs to be set inside the joints.

[0003] In the prior art, a Chinese patent with publication number CN214116141U discloses a pavement joint connection structure, including a drainage box and steel bars, an end cover is provided above the drainage box, a plurality of rows of drainage holes are evenly arranged on the end cover, two side surfaces connected to the pavement panel are provided with through holes connected to the steel bars, drainage pipes are provided at both ends of the drainage box, and the spacing between two adjacent rows of drainage holes is 5 to 10 cm; the height of the drainage box is the same as the thickness of the pavement panel, and the length of the drainage box is the same as the width of the pavement panel; by arranging a drainage box at the joint, the patent can avoid water accumulation from causing structural damage to the joint and improve the service life of the cement concrete pavement.

[0004] The above patent uses a drainage box to drain water when draining the joints, and an end cover is provided above the drainage box. However, the end cover may be damaged when a heavy vehicle is driven for a long time, so that the drainage box cannot be filtered, affecting the drainage at the joints. Therefore, a cement pavement joint connection device is proposed to solve the above problem. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a cement pavement joint connection device, which can achieve buffering of the end cover by setting a buffering vibration component and at the same time, can achieve knocking of the end cover to improve the anti-blocking effect of the end cover.

[0007] In some embodiments, an inner wall of the rectangular frame is fixedly connected to a tilting platform, an upper surface of the tilting platform is fixedly connected to a cylinder, and an arc groove is formed on the surface of the cylinder.

[0008] In some embodiments, a second spring is fixedly connected to the inner bottom wall of the cylinder, a rotating plate is fixedly connected to the top of the second spring, and a surface of the rotating plate is slidably connected to the inner wall of the cylinder.

[0009] In some embodiments, the upper surface of the rotating plate is rotatably connected to a vibration plate, the surface of the rotating plate is fixedly connected to a connecting rod, and the surface of the connecting rod is slidably connected to the inner wall of the arc groove.

[0011] In some embodiments, steel bars are provided inside the pavement one and the pavement two, and the drainage box is connected to the pavement one and the pavement two through the steel bars.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, when the end cover in the utility model is squeezed by gravity, the end cover will squeeze the two damping sliders under the rotation of the rotating rod, and the two damping sliders squeeze the spring 1, and the amplitude is expanded by the two springs 1, so as to achieve a buffering effect on the end cover, thereby realizing a protective function for the end cover;

[0014] Second: in the utility model, when the end cover is squeezed by gravity, it drives the fixed seat to descend synchronously, and the fixed seat drives the lower pressure rod to squeeze the connecting rod, causing the connecting rod to slide and descend in the arc groove opened on the cylinder. When sliding and descending, it drives the rotating plate to descend synchronously, and the rotating plate drives the vibration plate to descend. When the connecting rod moves inside the arc groove and separates from the lower pressure rod, the rotating plate will drive the vibration plate to impact upward through the elastic force of spring 2, causing vibration to the end cover, which can avoid clogging of the leakage hole opened on the end cover and affect the drainage efficiency.

[0015] The invention solves the problem that the existing end cover may be damaged when a heavy vehicle is driven for a long time, thereby failing to filter the drainage box and affecting the drainage at the joint. BRIEF DESCRIPTION OF THE DRAWINGS
