Description

Technical Field

[0001] The utility model relates to a paving device. Background Art

[0002] At present, the pavers used in polyurethane concrete construction are large pavers, which cannot continue paving within the remaining 2.5m width of the bridge deck. During the construction process, after the middle lane is paved, the remaining narrow lane with drainage holes can only be paved manually, which is time-consuming and labor-intensive, reduces construction efficiency, and increases construction costs.

[0003] Most of the existing small-scale paving equipment is aimed at asphalt mixtures and has heating, stirring and paving functions. However, polyurethane concrete is different from traditional paving materials and does not need to be rolled, but needs to be vibrated and leveled. Therefore, traditional equipment cannot meet construction needs. For this reason, the Chinese utility model patent "A Polyurethane Concrete Paver" previously applied by the applicant, with patent number ZL201821463369.6 (authorization announcement number CN208965374U) discloses a polyurethane concrete paver including a frame, on which an auger for stirring polyurethane concrete and a vibration mechanism located at the rear side of the auger are provided, and the frame is also provided with a distribution bin for loading polyurethane concrete, the distribution bin is arranged in front of the vibration mechanism, and the auger is arranged in the distribution bin.

[0004] Although the above patent discloses a small paver for polyurethane concrete construction, after the middle lane is paved, the remaining narrow lanes cannot be paved. Therefore, it is necessary to further improve the existing paver. Utility Model Content

[0027] The auger 2 is arranged in the chamber 11, and extends in the left-right direction, and is arranged to rotate around its own axis, and is used to stir the polyurethane concrete in the chamber 11. The second driving mechanism 5 is used to drive the travel wheel 12 and the auger 2 to rotate, and the power output end of the second driving mechanism 5 is connected to the travel wheel 12 and the auger 2. Specifically, the second driving mechanism 5 includes a second motor 51 installed on the body 1, a second driving wheel 52, a second transmission belt 53 for transmitting power to the travel wheel 12, and a third transmission belt 54 for transmitting power to the auger 2. Among them, the travel wheel 12 is located in front of the auger 2, and a driven wheel 13 is coaxially arranged. In this embodiment, the driven wheel 13 is installed on the mounting shaft 14. The second driving wheel 52 is located between the travel wheel 12 and the auger 2, and is installed on the output shaft of the second motor 51. The second transmission belt 53 surrounds the outer periphery of the driven wheel 13 and the second driving wheel 52, and the third transmission belt 54 surrounds the outer periphery of the second driving wheel 52 and the auger 2.

[0028] The two vertically arranged side panels on the left and right sides of the above-mentioned chamber 11 are vertical side panels 111. At least one of the two vertical side panels 111 is arranged to move only left and right relative to the auger 2 and is constrained on the auger 2. In this embodiment, an opening 111 is provided on the vertical side panel 111 for the corresponding end of the auger 2 to pass through. A gap is left between the circumference of the opening 111 and the corresponding position of the auger 2, and the vertical side panel 111 and the auger 2 are loosely matched. The auger 2 is rotatably arranged on the vertical side panel 111. The front and rear edges of the aforementioned vertical side panel 111 gradually tilt toward each other from top to bottom.

[0029] In order to transport the polyurethane concrete after being mixed evenly, a feeding mechanism 3 is provided on the machine body 1 for receiving the polyurethane concrete flowing out of the discharge port of the chamber 11 and transporting it backwards, and the feeding mechanism 3 is at least partially located below the chamber 11. In this embodiment, the feeding mechanism 3 is located behind the auger 2, and the feeding mechanism 3 includes a front drive wheel 31 and a rear drive wheel 32 arranged at intervals from front to rear, and a feeding belt 33 surrounding the periphery of the front drive wheel 31 and the rear drive wheel 32, and also includes a first driving mechanism 4 for driving the front drive wheel 31 or the rear drive wheel 32 to rotate, and the front drive wheel 31 or the rear drive wheel 32 is installed on the power output end of the first driving mechanism 4. Specifically, the first driving mechanism 4 includes a first motor 41, a first driving wheel 42 installed on the output shaft of the first motor 41, and a first driving belt 43 for transmitting power to the rear drive wheel 32, and the first driving belt 43 surrounds the periphery of the first driving wheel 42 and the rear drive wheel 32.

[0030] The front side of the bottom of the machine body 1 is provided with a thickness detection device for detecting the paving thickness on the ground, and the rear side of the machine body 1 is provided with a vibration plate 18 that can move up and down to level the paving material on the ground, and the vibration plate 18 can be detachably mounted on the machine body 1. The aforementioned thickness detection device is an infrared thickness detector 17.

[0031] After the equipment is turned on, the second motor 51 starts to run and is responsible for driving the walking wheel 12. The forward speed of the equipment can be adjusted as needed. The auger is also driven to rotate by the second motor 51, and the rotation speed can be adjusted as needed. There is an infrared thickness detector 17 on the front side of the machine body. After measuring the ground height, the height of the rear vibration plate 18 can be determined according to the input paving thickness, so as to accurately achieve thickness adjustment. The position of the vertical side plate is adjusted in place according to the paving width, and the adjustable width range is 0 to 2.5m. After the adjustment is completed, the mixed polyurethane mixture is poured into the feed port above the chamber. The mixture is mixed evenly by the auger and falls on the feeding belt 33 of the feeding mechanism. The running speed of the feeding belt 33 is controlled by the first motor 41. After the mixture falls on the feeding belt 33, it is transported to the paving entrance by the feeding belt 33. After the mixture is paved on the ground, the vibration plate 18 starts to work. The vibration plate is driven by a vibration motor (not shown) to vibrate and level the polyurethane mixture on the ground. The paving thickness is determined by the infrared detector 17 in front. After paving and leveling is completed, the next construction process can be carried out according to the paving structure design.
