Description

Technical Field

[0001] The invention relates to the technical field of asphalt paving equipment, in particular to a single-layer epoxy asphalt paving structure. Background Art

[0002] Single-layer epoxy asphalt is a mixture of epoxy resin, curing agent and matrix asphalt obtained through complex chemical modification. It forms a multi-component interpenetrating network three-dimensional structure material through precise component and phase design and chemical reaction. Epoxy resin is the continuous phase in the system, and matrix asphalt is the dispersed phase. This structure fundamentally changes the thermoplasticity of ordinary asphalt, greatly improves the high-temperature stability, and significantly improves the adhesion, tensile strength, elongation at break and low-temperature performance of the material. When this type of asphalt is used for paving, it needs to be used in conjunction with paving equipment. Paving equipment is a road construction equipment that is widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, stadiums, etc. It can roll sandy, semi-viscous and sticky soils, roadbed stabilized soils and asphalt concrete pavement layers.

[0003] Prior art, such as the patent with publication number CN219010883U, discloses a road epoxy asphalt paving equipment, including a base plate, an epoxy asphalt cylinder is fixedly installed on the top of the base plate, a stirring rod is rotatably installed inside the epoxy asphalt cylinder, side wall scraping rods are fixedly installed on both sides of the stirring rod, a bottom wall scraping rod is fixedly installed on the bottom of the stirring rod, a driven wheel is fixedly installed on the top of the stirring rod, a fixing frame is fixedly installed on the top of the base plate, and a twin motor is fixedly installed inside the fixing frame.

[0004] The above prior art has obvious beneficial effects, but still has shortcomings:

[0005] After the twin motors in the above-mentioned prior art are started, the bottom output end of the twin motors can drive the mounting frame A to rotate, thereby driving the rotating rollers to rotate, and rotating and compacting the asphalt sprayed through the asphalt paving nozzle to improve the asphalt paving effect. In addition, the asphalt compacted by the rotating rollers can be rolled for the second time when the device moves, thereby improving the asphalt paving effect. However, there are the following problems in the asphalt paving operation. First, when the rotating rollers perform the first rotational compaction of the asphalt, the rollers are driven by the twin motors as driving force. The driving speed of the rollers is different from that of the equipment, resulting in not only compaction of the asphalt surface, but also friction with the rotation. This will cause the asphalt to be attached to the roller surface or splashed due to the friction when compacting. If the asphalt is compacted only by the subsequent rollers, the asphalt paving effect is not ideal. At the same time, the asphalt is kept from solidifying only by the stirring process during paving, and the asphalt temperature will decrease with time. If the construction time is long, solidification will still exist, which is not conducive to continuous operation. For this reason, a single-layer epoxy asphalt paving structure is proposed.

[0029] like Figure 1-4 As shown, the asphalt paving structure in the present invention is similar to the existing paving equipment structure, such as a road epoxy asphalt paving equipment with publication number CN219010883U. The main improvement of the present invention is that the counterweight 303 structure provides compaction stability for the pressure roller 305, and the scraper 307 adopts an inclined structure to keep the pressure roller 305 scraping while flattening the compacted asphalt surface again. The electric heating plate 205 arranged on the inner wall of the storage chamber 202 is connected to the battery compartment 206 for heating, and can also provide continuous constant temperature heating for the asphalt stirred by the stirring frame 203, maintain the asphalt temperature, avoid cooling and solidification, thereby providing a stable asphalt compaction and paving process; the pressure roller 305 and the electric heating plate 205 in the present invention are both prior art. When using this paving structure for asphalt paving operations, the user can fasten the bolt 102 at one end of the plate frame 101 of this structure to the work The buckle 102 and the handle frame 103 fixedly connected at one end of the plate frame 101 can not only be conveniently connected to the engineering equipment, but also convenient for the user to hold and push the equipment, and cooperate with the rollers 105 connected to the roller frames 104 on both sides of the bottom to travel, the operation method is flexible and changeable, and the structure is stable.

[0030] like Figure 2-3As shown, the paving frame 2 includes an outer box frame 201, and a storage cavity 202 is opened inside the outer box frame 201, a stirring frame 203 is arranged inside the storage cavity 202, and one end of the stirring frame 203 is connected to a motor 204, an electric heating plate 205 is embedded in the inner wall of the storage cavity 202, and a battery compartment 206 is connected to an outer wall of one side of the outer box frame 201, and a discharge frame 207 is connected to the bottom end of the outer box frame 201, and a discharge plate 208 is connected to the bottom end of the discharge frame 207, and an adjusting bolt 209 is penetrated at one end of the discharge plate 208. In this structure, asphalt paving is performed. When setting, the operator can first start preheating through the electric heating plate 205 connected to the battery compartment 206 to increase the temperature inside the storage chamber 202, and keep the temperature after pouring the asphalt material. Then, the motor 204 drives the stirring frame 203 to rotate inside the storage chamber 202 and continuously stirs the asphalt material. After the asphalt is put into the storage chamber 202, it will be continuously discharged along the bottom along the discharge frame 207 connected to the bottom end of the storage chamber 202. The user adjusts the angle of the discharge plate 208 according to the paving thickness and paving amount in advance. By adjusting the angle of the discharge plate 208 The adjusting bolts 209 at both ends are rotated and tightened with the discharge rack 207, so that the expansion angle of the discharge plate 208 can be fixed, so that it maintains a certain expansion angle, exposing the opening, and then the asphalt can be discharged from the bottom through the opening. As the structure moves, the asphalt is evenly laid on the paved ground.

At the same time, the scraped asphalt and the compacted asphalt surface will be flattened again as it moves, completing the continuous paving process. This structure The counterweight 303 is placed through the front frame 301 connected to the end and the slot cavity 302 opened at the top, which increases the weight of the front end and the pressure of the pressure roller 305, providing pressure stability and controllability for the compaction operation. The adjustable scraper 307 is fixed in an inclined manner, with one end in contact with the pressure roller 305 and the other end in contact with the ground.
