[0002] Asphalt heaters are required at highway maintenance sites to heat asphalt pavements. Asphalt heaters in existing equipment are generally installed on vehicles, and one heater includes one or two heating boxes. At present, on-site hot regeneration construction requires the mixture temperature to be between 150 degrees and 160 degrees. In order to improve the temperature of the asphalt pavement mixture and the construction efficiency, the existing operation method generally uses at least two heaters for synchronous construction. The two heaters are independent structures and are driven by corresponding vehicles. In the prior art, the transportation cost and personnel cost of the heater to the site are relatively high, and during the operation of the heater, the distance between the equipment is difficult to control, and there are defects such as high heat energy loss.

DETAILED DESCRIPTION

[0027] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0028] This embodiment provides an on-site hot-regeneration asphalt composite heater, which can be used in the construction of asphalt pavement.

[0029] As shown in the reference figure, the heating machine mainly includes a vehicle body 1 and a first heating unit 5. The first heating unit 5 is fixed under the chassis of the vehicle body 1. The first heating unit 5 includes two heating boxes arranged in parallel. The two heating boxes can be used to heat the road surface below.

[0030] A track 2 is provided on the upper surface of the chassis of the vehicle body 1, and the mobile frame 3 can move along the track 2. In this embodiment, a second heating unit 4 is fixedly installed on the mobile frame 3. The second heating unit 4 has the same structure as the first heating unit 5, and both include two heating boxes. The mobile frame 3 is designed to be able to move along the track 2 in order to enable the second heating unit 4 to switch between the vehicle body 1 and the road surface. When the device needs to be moved to the construction site, the mobile frame 3 is moved to the vehicle body 1 via the track 2. When working at the construction site, the mobile frame 3 is moved to the ground via the track 2 so that the second heating unit 4 heats the road surface below.

[0031] In this embodiment, in order to facilitate the movement of the second heating unit 4, a first lifting mechanism 7 and a second lifting mechanism 8 are provided. The first lifting mechanism 7 is provided on the vehicle body 1, and is located at the end of the vehicle body 1. Specifically, a movable bracket 9 that can be driven by the first lifting mechanism 7 to realize lifting movement is provided at the end of the track 2 of the vehicle body 1. When the mobile frame 3 walks to the end on the track 2, the front leg 32 on the front side moves to the position of the movable bracket 9. In this way, when the movable bracket 9 is driven to move downward by the first lifting mechanism 7, the front leg 32 of the mobile frame 3 can move downward accordingly. The second lifting mechanism 8 is provided on the mobile frame 3, and is connected to the rear leg 33 of the mobile frame 3, that is, the rear leg 33 can be driven to move up and down by the second lifting mechanism 8.

[0032] The principle of the first lifting mechanism 7 and the second lifting mechanism 8 cooperating to control the movement of the moving frame 3 is as follows: when at the construction site, firstly, the second lifting mechanism 8 is lowered, so that the rear legs 33 fall on the ground, so that the moving frame 3 moves out to support the rear part, and the moving frame 3 moves to the end along the track 2, so that the front legs 32 are located on the movable bracket 9 (refer to Figure 2 As shown in FIG. 1 ), the first lifting mechanism 7 is started to descend and the second lifting mechanism 8 is started to retract, and the mobile frame 3 gradually falls until it reaches the working position (refer to FIG. 1 ). Figure 3 As shown in FIG. 1 ), during this process, the rear legs 33 are always in contact with the ground to achieve support, and the moving frame 3 is moved out through the above steps. On the contrary, when the device needs to be transported, the moving frame 3 is moved to Figure 1 In the state shown, the rear legs 33 can be folded up.

[0033] In this embodiment, the first lifting mechanism 7 and the second lifting mechanism 8 are mainly used for the lifting drive of the two ends of the mobile frame 3. It is preferably controlled by a cylinder, and other lifting drive structures can also be used. In order to ensure stability during the lifting process, a corresponding guide structure can be set. Driving the lifting movement of components is a conventional technical means and will not be further explained here.

[0034] As described above, through the cooperation of the first lifting mechanism 7 and the second lifting mechanism 8, the movable frame 3 drives the second heating unit 4 to move to the ground and to a suitable height, and then the movable frame 3 is connected to the vehicle body 1 through the traction mechanism, and the movable frame 3 can be driven by the vehicle body 1 to move, so that the first heating unit 5 and the second heating unit 4 can heat the asphalt pavement synchronously.

[0035] In this embodiment, if Figure 4The device state in the final working state is shown in FIG. A horizontal oil cylinder 6 is arranged under the chassis of the vehicle body 1, and the horizontal oil cylinder 6 is connected to a first connecting member 61. A second connecting member 35 is arranged on the front leg 32 of the movable frame 3. When the movable frame 3 is moved out to the working position, the first connecting member 61 and the second connecting member 35 are in corresponding positions. At this time, the first connecting member 61 can be driven by the horizontal oil cylinder 6 to move toward the second connecting member 35. After the two are combined, they are connected together by the connecting pin 10. In this way, when the vehicle body 1 moves, the movable frame 3 can be driven to move. Furthermore, the horizontal oil cylinder 6 can adjust the front and rear positions of the movable frame 3 by telescoping.

[0036] refer to Figure 5 As shown, in this embodiment, the moving frame 3 mainly includes a crossbeam 31, a front leg 32 and a rear leg 33. The second heating unit 4 is installed below the crossbeam 31. The front leg 32 is provided with a front running wheel 36 to facilitate its movement along the track 2, and the rear leg 33 is provided with a rear running wheel 34 to facilitate its movement along the road surface. It should be understood that in order to avoid position interference, the height of the front leg 32 is less than the rear leg 33. When the moving frame 3 is on the vehicle body 1, the rear leg 32 at its end can be located outside the track 2.
