Description

Technical Field

[0001] This utility model relates to the field of hot rolling technology for road surfaces, and in particular to a hot rolling structure for asphalt pavement. Background Technology

[0002] In modern road construction, asphalt pavement has become the main paving form for transportation infrastructure such as highways and urban roads due to its excellent smoothness, low noise, and ease of maintenance. Hot compaction is the core step in asphalt pavement construction. By compacting the asphalt mixture under high temperature, the density, strength, and durability of the pavement can be effectively improved, which is crucial for ensuring the pavement's service performance and lifespan.

[0003] Current hot rolling structures for asphalt pavements mostly achieve heat exchange by injecting hot water into hollow rollers. However, the internal space is too large, resulting in a large amount of hot water not being able to fully exchange heat, and the heat exchange area is small, leading to poor heating effect. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hot rolling structure for asphalt pavement, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a hot rolling structure for asphalt pavement, including a connecting plate. A connecting frame is rotatably connected to the center of one side of the connecting plate, and a rolling roller is rotatably connected to the center of one side of the connecting frame. Rotary shaft tubes are fixedly connected to the centers of both ends of the rolling roller, and rotating joints are fixedly connected to the ends of the two rotating shaft tubes. A plurality of heat-conducting fins are fixedly connected to the inner wall of the rolling roller, and these heat-conducting fins are arranged in a radial annular array centered on the axis of the rolling roller. A counterweight cylinder is fixedly connected to the side of the plate away from the inner wall of the flattening roller. An instant water heater and a circulating water pump are fixedly connected to one side of the top surface of the connecting plate. The output end of the circulating water pump is fixedly connected to and communicates with the input end of the instant water heater. An inlet water insulation pipe is fixedly connected to the output end of the instant water heater. A return water insulation pipe is fixedly connected to the suction end of the circulating water pump. One end of the return water insulation pipe and the inlet water insulation pipe are respectively fixedly connected to one side of two rotating joints. The return water insulation pipe and the inlet water insulation pipe are rotatably connected to the rotating shaft tube through two rotating joints.

[0006] Preferably, in any of the above embodiments, the connecting frame is connected to the steering mechanism of the flattening vehicle, and the length of the flattening roller is greater than the width of the connecting plate.

[0007] The technical effect achieved by adopting the above solution is that the connecting frame can be rotated by the steering mechanism of the rolling mill, thereby adjusting the rolling direction.

[0008] Preferably, in any of the above embodiments, push plates are fixedly connected to both sides of the inner wall of the counterweight cylinder, a number of counterweight steel balls are installed on the inner wall of the counterweight cylinder, the counterweight cylinder is coaxially arranged with the flattening roller, a gap is left between the two sides of the counterweight cylinder and the two sides of the inner wall of the flattening roller, and the number of counterweight steel balls fills half of the internal space of the counterweight cylinder.

[0009] The technical effect achieved by the above scheme is that, through the counterweight steel balls and push plate inside the counterweight cylinder, the counterweight steel balls can be lifted by the push plate as the cylinder rotates, and then fall off continuously as the cylinder flips, thereby generating a certain impact force during the rolling process and improving the rolling effect.

[0010] Preferably, in any of the above solutions, all of the heat-conducting fins are made of heat-conducting material, and the length of the heat-conducting fins is equal to the length of the flattening roller.

[0011] The technical effect achieved by adopting the above solution is that the heat conduction effect can be improved by using heat-conducting fins made of heat-conducting material, and the heat exchange area can be maximized.

[0012] Preferably, the outer wall of the counterweight cylinder is wrapped with heat-insulating material, as described in any of the above embodiments.

[0013] The technical effect achieved by adopting the above solution is that it can reduce the conduction of heat to the counterweight cylinder and reduce heat waste.

[0014] This utility model has the following advantages:

[0015] 1. The hot rolling structure for asphalt pavement creates a narrow water flow space by separating the counterweight cylinder from the inner wall of the rolling drum, allowing the heat in the water to be fully released during flow, thus improving the efficiency of heat exchange. At the same time, the counterweight cylinder is supported by several heat-conducting fins, which can increase the heat absorption area of ​​heat exchange, improve heat exchange efficiency, and enhance the heating effect. The water flow inside the rolling drum is circulated and heated through the connection between the instant hot water heater, the circulating water pump, and the return water insulation pipe and the inlet water insulation pipe.

[0016] 2. The hot rolling structure of this asphalt pavement uses several counterweight steel balls and push plates inside the counterweight cylinder to make several counterweight steel balls be lifted by the push plates as they rotate, and then fall off continuously as they flip, so as to generate a certain impact force during rolling and improve the rolling effect.

A plurality of heat-conducting fins 9 are fixedly connected to the inner wall of the rolling roller 5. The plurality of heat-conducting fins 9 are arranged in a radial annular array with the axis of the rolling roller 5 as the center. The side of the plurality of heat-conducting fins 9 away from the inner wall of the rolling roller 5 shares a common... A counterweight cylinder 10 is fixedly connected. An instant water heater 2 and a circulating water pump 3 are fixedly connected to one side of the top surface of the connecting plate 1. The output end of the circulating water pump 3 is fixedly connected to and communicates with the input end of the instant water heater 2. An inlet water insulation pipe 13 is fixedly connected to the output end of the instant water heater 2.

The return water insulation pipe 7 and the inlet water insulation pipe 13 are rotatably connected to the rotating shaft tube 8 through two rotating joints 6.

[0023] As an optional technical solution of this utility model, the connecting frame 4 is connected to the steering mechanism of the flattening vehicle. The length of the flattening roller 5 is greater than the width of the connecting plate 1. The connecting frame 4 can be rotated by the steering mechanism of the flattening vehicle to adjust the rolling direction.

[0024] As an optional technical solution of this utility model, push plates 11 are fixedly connected to both sides of the inner wall of the counterweight cylinder 10. Several counterweight steel balls 12 are installed on the inner wall of the counterweight cylinder 10. The counterweight cylinder 10 and the flattening roller 5 are coaxially arranged. There is a gap between the two sides of the counterweight cylinder 10 and the two sides of the inner wall of the flattening roller 5. Several counterweight steel balls 12 fill half of the internal space of the counterweight cylinder 10. Through the several counterweight steel balls 12 inside the counterweight cylinder 10 and the push plates 11, the several counterweight steel balls 12 can be lifted by the push plates 11 as they rotate, and then fall continuously as they flip, so as to generate a certain impact force when flattening and improve the flattening effect.

[0027] The hot-compacted asphalt pavement structure requires the following steps for use:

[0028] 1) The water inside the flattening drum 5 is circulated and heated by connecting the instant water heater 2 with the circulating water pump 3 and the return water insulation pipe 7 with the inlet water insulation pipe 13.

[0029] 2) A narrower water flow space is created by separating the counterweight cylinder 10 from the inner wall of the flattening roller 5, so that the heat in the water can be fully released when it flows, thereby improving the efficiency of heat exchange.

[0030] 3) By supporting the counterweight cylinder 10 with several heat-conducting fins 9, the heat absorption area of ​​the heat exchange can be increased, thereby improving the heat exchange efficiency.

[0032] In summary, by creating a narrower water flow space between the counterweight cylinder 10 and the inner wall of the flattening roller 5, the heat in the water can be fully released during the flow, improving the efficiency of heat exchange. Simultaneously, the counterweight cylinder 10 is supported by several heat-conducting fins 9, which increases the heat absorption area, improves heat exchange efficiency, and enhances the heating effect. The connection between the instant water heater 2, the circulating water pump 3, the return water insulation pipe 7, and the inlet water insulation pipe 13 enables the water inside the flattening roller 5 to circulate and heat. The counterweight steel balls 12 inside the counterweight cylinder 10 and the push plate 11 allow the counterweight steel balls 12 to be lifted by the push plate 11 as the roller rotates, and then continuously fall as it flips, generating a certain impact force during the flattening process and improving the flattening effect.
