Description

Technical Field

[0001] The invention belongs to the technical field of asphalt pavement maintenance, and in particular relates to a high-performance asphalt mixture pavement maintenance device and process. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] Chinese patent CN109024186B discloses an asphalt pavement maintenance equipment, which relates to the field of road maintenance, including a storage box, a fixed block and a discharging funnel, wherein a feeding port is arranged at the top of the storage box; a stirring device is rotatably connected in the storage box; a sealing plate is slidably connected at the bottom end of the discharging funnel, and the discharging funnel is provided with two groups of discharging plates, each of which is provided with a plurality of baffles; one group of the discharging plates is slidably connected to the discharging funnel, and the other group of the discharging plates is fixedly connected to the discharging funnel, and a sliding component for driving the discharging plates to move is arranged on the discharging funnel; after the discharging plates are slidably connected, the baffles on the two groups of the discharging plates are close to or away from each other; after feeding from the feeding port on the storage box, the materials are discharged from the discharging funnel, and during the process of discharging from the discharging funnel, the discharging plate is slidably connected on the discharging funnel, so as to stir the materials in the discharging funnel, thereby reducing the blockage of the discharging funnel when discharging, so as to facilitate the maintenance of the asphalt pavement.

[0004] Based on the asphalt pavement maintenance process and the required equipment, there are many situations that may occur when maintaining the asphalt pavement, but not limited to the one mentioned below. When maintaining the asphalt pavement, the cracks in the pavement will be filled with melted filling materials and poured, and then wait for them to dry naturally;

[0005] When the existing asphalt pavement is maintained, the filling material is heated and melted by a heating tank. However, when different filling materials are needed, if different materials are directly put into the material tank, it is easy to mix with the residual material, resulting in the material not reaching the required strength. In addition, when pouring, it is easy to contact with impurities on the ground, resulting in insufficient strength.

[0006] Based on the above-mentioned problems, we found that it is difficult for the asphalt mixture pavement maintenance device in the prior art to avoid the above situations at the same time. Therefore, we proposed an asphalt mixture pavement maintenance device that can easily replace the material tank and perform preliminary cleaning of the road surface. Summary of the invention

[0007] The purpose of the present invention is to provide an existing high-performance asphalt mixture pavement maintenance device and process, which has the advantages of being able to easily replace the material tank and perform preliminary cleaning of the pavement.

The outer tank and the inner tank are used to hold the maintenance and repair materials, and the materials are melted by the main heating tank, the driving motor and the stirring shaft. Then they can be pumped out and discharged from the device to maintain the road surface. When the filling material needs to be replaced, the top cover can be removed, and the inner tank can be taken out, and the new filling material and the inner tank used for holding are connected to the outer tank. When the inner tank is placed in the outer tank, the pressure rod presses the top plug, so that a gap is generated between the top plug and the outer frame, so that the filling material can flow down from the outer frame.

[0016] By adopting the above technical solution, by setting the first spring and the inner tube, it is convenient to connect and support the top plug, and when the pressure rod presses the top plug, the inner tube extends from the inside of the outer tube. At this time, the first spring accumulates force and rebounds when the pressure rod stops pressing to reset the top plug.

[0017] The present invention is further configured as follows: a leak-proof ring is bolted to the bottom of the inner tank, and the inner side of the leak-proof ring is clamped to the top of the connecting bucket.

[0028] A maintenance process for a high-performance asphalt mixture pavement comprises the following steps:

[0029] S1. Open the door panel and put the repair and filling materials into the inner tank. The main heating tube heats the inner tank to melt the internal materials. At the same time, the driving motor stirs the materials inside the inner tank through the stirring shaft to assist in melting.

[0030] S2. The melted material is pumped out by the material pump and falls through the discharge pipe and the drop bucket to inject the repair material into the position to be repaired. When the device passes the working position, the roller rolls the repair position to make it flat;

[0031] S3. The fan blows out air through the air duct to disperse the impurities on the ground to avoid contact with the repair material and cause insufficient repair strength.

[0032] In summary, the present invention has the following beneficial effects:

[0033] By setting up a carrier, the device can be moved in conjunction with the rollers installed at its bottom. The outer tank and the inner tank are used to hold the maintenance and repair materials, and the materials are melted by the main heating tank, the driving motor and the stirring shaft. Then they can be pumped out by the material pump and discharged from the discharge pipe and the drop bucket to inject and maintain the road surface. The pressure roller flattens the repair position. When the filling material needs to be replaced, the top cover can be removed through the matching ring and the assembly ring, and the inner tank is taken out and connected to the outer tank together with the new filling material and the inner tank used for holding.
