Abstract
Description
Technical Field
[0001] The utility model relates to the field of asphalt pavement repair equipment, in particular to an asphalt pavement repair device. Background Art
[0002] Asphalt pavement is a variety of pavement formed by paving and rolling asphalt concrete. Asphalt binder improves the ability of paving aggregate to resist damage to the pavement caused by traffic and natural factors, making the pavement smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, its base layer can also use rigid cement concrete or semi-rigid hydraulic materials.
[0003] Asphalt pavement is a common road material. It has the advantages of waterproof, anti-aging and noise reduction, but it is also easily affected by factors such as temperature, load, material and construction, resulting in cracks of different types and degrees. Cracks not only affect the performance and appearance of the pavement, but also lead to the destruction of the pavement structure and the penetration of water, which accelerates the aging and damage of the pavement. There are many reasons for the cracks in asphalt pavement. On the one hand, under the action of vehicle load, the tensile stress at the bottom of the asphalt layer exceeds the tensile strength of the asphalt mixture, resulting in the fracture of the bottom of the asphalt layer, which is reflected to the asphalt surface layer, resulting in structural cracks; on the other hand, due to temperature changes, the temperature shrinkage of the asphalt mixture or the temperature fatigue stress exceeds the tensile strength of the asphalt mixture, which also causes the asphalt surface layer to crack and form temperature cracks; there are also cracks in the base or old pavement due to the reflection of the cracks in the new asphalt surface layer, and the crack form of the asphalt surface layer is basically the same as the crack form of the base or old pavement, resulting in reflection cracks; and fatigue cracks such as mesh cracks or transverse cracks in the asphalt surface layer caused by temperature fatigue or load fatigue. No matter what the reason for the formation of cracks, they all have one thing in common, that is, all the cracks are irregular, which brings thorny problems to the repair work; if the road surface is severely damaged, the entire piece can be cut out and refilled; and for the case where only cracks appear but do not affect the road traffic, the cracks are usually repaired. Existing repair methods include asphalt filling method, slotting and patching method, hot melt method, pre-coating agent repair method, mixed caulking method, hot pressing method, surface sealing method, particle refueling method, colloid penetration method, etc., but because the cracks are irregular, they need to be repaired along the direction of the cracks. Taking asphalt filling as an example, the staff has to constantly adjust the angle and direction of the asphalt heating equipment along the cracks, which is very troublesome, and it is not convenient for the asphalt to flow into the cracks accurately.

[0032] The heating box 4 is a common knowledge that the heating box 4 is an existing product on the market and has a heating component, which will not be described in detail here; Figures 1 to 4 As shown, the heating box 4 is fixedly installed on the cart body 1; see Figure 5 and Figure 6 The bottom of the side of the heating box 4 is shown to have a first discharge port 5, as shown in FIG. Figure 6 As shown, the first discharge port 5 has an edge extending outward, and its end is located in the guide groove 7; the lower part of the heating box 4 has a fixedly connected positioning shaft 6, Figure 4 and Figure 6 It shows that the positioning shaft 6 is located near the first discharge port 5;
[0033] The guide groove 7, such as Figure 5 and Figure 6As shown, one end of the guide groove 7 is movably connected to the positioning shaft 6; the guide groove 7 is located vertically below the first discharge port 5; wherein the guide groove 7 can rotate horizontally clockwise or counterclockwise with the positioning shaft 6 as the axis; Figure 3 As shown, the width of the guide groove 7 is greater than the width of the first discharge port 5. When the guide groove 7 rotates, the first discharge port 5 is always within the width of the guide groove 7, so that the asphalt flowing out of the first discharge port 5 can always flow into the guide groove 7; Figure 6 It is shown that the other end of the guide groove 7 has a first outlet 8; Figure 5 and Figure 6 The guide groove 7 is shown to further include a fixedly connected connecting frame 9, the other end of which is movably connected to the positioning shaft 6; the connecting frame 9 includes a movably connected guide rod 10, Figure 6 The guide rod 10 is shown to be at a vertical angle, and the lower end of the guide rod 10 is lower than the height of the first outlet 8;
[0034] Gravel Box 11, Figure 1 , Figure 2 , Figure 3 and Figure 4 It is shown that the gravel box 11 is fixedly installed on the cart body 1; Figure 2 , Figure 4 , Figure 5 and Figure 6 The second discharge port 12 is shown below the gravel box 11, and the second discharge port 12 is connected to a discharge hose 13, and the discharge hose 13 has a second outlet 14, and the discharge hose 13 is preferably a metal hose; the second outlet 14 is a metal pipe fixedly connected to the discharge hose, and the second outlet 14 is arranged parallel to the first outlet 8 and fixedly connected. Figure 6 As shown, the second outlet 14 is located at the rear, that is, the second outlet 14 is located at Figure 6 The left side of the first outlet 8 is pushed by pushing the push handle 2 to move the cart body 1 forward (towards Figure 6 When the vehicle is traveling on the right side of the center, the second outlet 14 is located behind the first outlet 8 ( Figure 6 On the left side of the first outlet 8).
[0035] In the use of the utility model, the heating box 4 is used to load the asphalt raw material and heat it, and the melted asphalt flows out through the first discharge port 5, the guide groove 7 and the first outlet 8 in sequence. Since the guide groove 7 is movably installed on the positioning shaft 6, the end of the guide rod 10 can be at least partially inserted into the gap of the asphalt road. In the process of pushing the cart body 1 along the gap, the guide rod 10 drives the first outlet 8 and the guide groove 7 to swing with the positioning shaft 6 as the axis in the friction with the inner wall of the gap, so that the asphalt fluid flows into the gap, and the route of pushing the cart body 1 does not need to be too precise to accurately fill the asphalt into the gap, which solves the problem that the staff currently needs to constantly adjust the angle and direction of the asphalt heating equipment along the crack, and the asphalt is not convenient to accurately flow into the crack.
