Description

Technical Field

[0001] The utility model relates to the technical field of asphalt cold recycled materials, in particular to a compaction treatment device for asphalt cold recycling. Background Art

[0002] Asphalt cold recycled materials refer to materials that are recycled, processed, and reused from old asphalt pavement materials (including asphalt surface layer materials and part of the base course materials) through cold recycling technology.

[0003] When compacting an asphalt cold recycled material pavement, a compaction treatment device is required. In the prior art, such a device is a road roller, which has no difference in structure from a conventional road roller for an asphalt pavement.

[0004] However, since asphalt cold recycled materials are cold recycled and their laying temperature is normal temperature, compared with traditional asphalt pavements, when they are compacted, small particles in the mixture are not easy to fill the gaps between large particles, and the particles are not easy to produce plastic deformation. Therefore, a new compaction treatment device for asphalt cold recycling is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model aims to solve at least one of the technical defects.

[0006] For this reason, an object of the utility model is to provide a compaction treatment device for asphalt cold recycling to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

[0007] To achieve the above object, an embodiment of one aspect of the utility model provides a compaction treatment device for asphalt cold recycling, including a machine body, an oil engine, a chain, a main shaft, and a pressing roller. An oil engine is installed on the top of the machine body. The outer surface of the sprocket installed on the output end of the oil engine is movably connected to the main shaft through a chain, and the main shafts are linked through sprockets and chains;

[0008] The outer surface of the main shaft is fixedly connected with a pressing roller, and the pressing roller is movably connected inside the machine body;

[0009] A handle is fixedly connected to the rear of the machine body, and a storage battery is installed on the top of the machine body;

[0010] Fixed arms are fixedly connected to both sides of the machine body, and a bottom plate is fixedly connected to the bottom end of the fixed arms;

[0011] An elastic layer is fixedly connected to the bottom of the bottom plate, and a heating layer is fixedly connected to the bottom of the elastic layer. The heating layer is movably connected to the road surface;

[0012] The heating layer has a plurality of bent electric heating wires inside.

[0013] Preferably, according to any of the above solutions, the oil engine includes a fuel tank and an engine, and the main shaft is horizontally arranged.

[0014] With the above technical solution: This device is specifically used for compacting the road surface of asphalt cold recycled material.

[0015] Preferably, according to any of the above solutions, the pressing roller consists of a roller body and several reinforcing ribs from outside to inside, and there are two pressing rollers arranged in parallel.

[0016] With the above technical solution: This device is driven by an oil engine. When the oil engine works, it outputs power and drives a single main shaft and a single pressing roller to rotate through a sprocket and a chain. This pressing roller then drives another main shaft and pressing roller to rotate through a sprocket and a chain. The pressing roller is made of alloy steel and rotates counterclockwise. The machine body moves forward towards the heating layer. When the pressing roller rotates, it compresses the asphalt recycled material road surface. As the pressing roller continuously rolls, the small particles in the mixture start to fill the gaps between the large particles, and the contact area between the particles gradually increases. The pressure exerted by the pressing roller increases the frictional force between the particles, and the particles undergo plastic deformation under mutual extrusion, further reducing the void ratio.

[0017] Preferably, according to any of the above solutions, the storage battery supplies power to the heating layer, and the fixed arm is riveted to the machine body at multiple points.

[0018] With the above technical solution: The core structure of this device is: a fixed arm, a bottom plate, an elastic layer, and a heating layer. The core advantage of this device is: A heating mechanism is pre-installed in front of the machine body and installed by the fixed arm. The heating layer has electric heating wires with multiple bends inside. The heating layer is movably connected to the ground. Before rolling the road surface, it can pre-heat the recycled asphalt road surface, and then two pressing rollers are used for rolling. Since the temperature of the recycled asphalt road surface is relatively low, it softens, increasing the fluidity of the asphalt. During the rolling process, the softened asphalt is more easily compacted, thereby improving the density and flatness of the road surface. Pre-heating before rolling can effectively improve the rolling effect;

[0019] When the pre-heated asphalt road surface is rolled, due to the increased fluidity of the asphalt, the resistance received by the pressing roller will correspondingly decrease. This not only helps the stable operation of the device but also can extend the service life of the roller compactor to a certain extent, enhance the adhesion between the new and old materials in the recycled asphalt layer, and ensure the overall strength and stability of the recycled asphalt road surface.

[0020] Preferably, according to any of the above solutions, below the bottom plate are an elastic layer and a heating layer in sequence.

[0021] Preferably, according to any of the above solutions, the edge of the elastic layer is wavy, the heating layer is located in front of the machine body, and the length of the heating layer is greater than the length of the pressing roller.

[0022] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0023] 1. For this compaction treatment equipment for asphalt cold recycling, through the cooperative setting of the fixed arm, bottom plate, elastic layer, and heating layer, a preheating mechanism is pre-installed in front of the machine body and installed by the fixed arm. The heating layer has multiple bent electric heating wires inside, and the heating layer is movably connected to the ground. Before rolling the road surface, it can preheat the recycled asphalt road surface, and then two rollers are used for rolling. Since the temperature of the recycled asphalt road surface is relatively low, it is softened, increasing the fluidity of the asphalt. During the rolling process, the softened asphalt is more easily compacted, thereby improving the density and flatness of the road surface. Preheating before rolling can effectively improve the rolling effect.

[0024] 2. For this compaction treatment equipment for asphalt cold recycling, when the preheated asphalt road surface is rolled, due to the enhanced fluidity of the asphalt, the resistance received by the rollers will be correspondingly reduced. This not only facilitates the stable operation of the device but also can, to a certain extent, extend the service life of the roller press, enhance the adhesion between the new and old materials in the recycled asphalt layer, and ensure the overall strength and stability of the recycled asphalt road surface.

[0036] A handle 6 is fixedly connected to the rear of the machine body 1, and a storage battery 7 is installed on the top of the machine body 1;

[0038] An elastic layer 10 is fixedly connected to the bottom of the bottom plate 9, and a heating layer 11 is fixedly connected to the bottom of the elastic layer 10. The heating layer 11 is movably connected to the road surface;

[0039] The heating layer 11 has multiple bent electric heating wires inside.

[0040] Embodiment 1: The oil engine 2 includes a fuel tank and an engine, and the main shaft 4 is arranged horizontally. This device is dedicated to the road surface compaction of asphalt cold recycling materials. The pressure roller 5 consists of a roller body and several reinforcing ribs from the outside to the inside, and two pressure rollers 5 are arranged in parallel.

[0041] Embodiment 2: Below the bottom plate 9 are an elastic layer 10 and a heating layer 11 in sequence. The edge of the elastic layer 10 is wavy, the heating layer 11 is located in front of the machine body 1, and the length of the heating layer 11 is greater than the length of the pressure roller 5.

[0042] The working principle of the present utility model is as follows:

[0043] This device is driven by a fuel engine 2.

This pressure roller 5 in turn drives another main shaft 4 and a pressure roller 5 to rotate through a sprocket and a chain 3. The pressure roller 5 is made of alloy steel and rotates counterclockwise. The machine body 1 moves forward towards the heating layer 11. When the pressure roller 5 rotates, it compacts the asphalt recycled material pavement. As the pressure roller 5 continuously rolls, the small particles in the mixture start to fill the gaps between the large particles, and the contact area between the particles gradually increases. The pressure applied by the pressure roller 5 increases the frictional force between the particles, and the particles undergo plastic deformation under mutual extrusion, further reducing the void ratio.

[0044] A heating mechanism is pre-installed in front of the machine body 1 and installed by a fixed arm 8. The heating layer 11 has multiple bent electric heating wires inside. The heating layer 11 is movably connected to the ground. Before rolling the pavement, it can pre-heat the recycled asphalt pavement, and then two pressure rollers 5 perform rolling. Since the temperature of the recycled asphalt pavement is relatively low, it is softened, increasing the fluidity of the asphalt.

[0045] Compared with the prior art, the present utility model has the following beneficial effects compared to the prior art:

[0046] 1. For this compaction treatment equipment for asphalt cold recycling, through the cooperative setting of the fixed arm 8, the bottom plate 9, the elastic layer 10, and the heating layer 11, a heating mechanism is pre-installed in front of the machine body 1 and installed by the fixed arm 8. The heating layer 11 has multiple bent electric heating wires inside. The heating layer 11 is movably connected to the ground. Before rolling the pavement, it can pre-heat the recycled asphalt pavement, and then two pressure rollers 5 perform rolling. Since the temperature of the recycled asphalt pavement is relatively low, it is softened, increasing the fluidity of the asphalt. During the rolling process, the softened asphalt is more easily compacted, thereby improving the density and flatness of the pavement. Pre-heating before rolling can effectively improve the rolling effect.

[0047] 2. For this compaction treatment equipment for asphalt cold recycling, when the pre-heated asphalt pavement is rolled, due to the enhanced fluidity of the asphalt, the resistance received by the pressure roller 5 will be correspondingly reduced. This not only facilitates the stable operation of the device but also can, to a certain extent, extend the service life of the roller press, enhance the adhesion between the new and old materials in the recycled asphalt layer, and ensure the overall strength and stability of the recycled asphalt pavement.
