Description

Technical Field

[0001] This invention relates to the field of road engineering technology, and in particular to an intelligent temperature-controlled asphalt heating and insulation transport vehicle. Background Technology

[0002] Asphalt is a viscoelastic material whose physical state and properties are significantly affected by temperature. This dictates that heating and insulation are necessary during transportation. When asphalt is at a high temperature, its viscosity decreases significantly, exhibiting good fluidity, which facilitates transportation and paving through circulating heat-conducting components. However, if the temperature drops below 100℃, the viscosity of the asphalt increases sharply, gradually solidifying into a solid or semi-solid state. This not only prevents smooth output through the discharge components but may also clog pipelines, severely impacting transportation efficiency and construction progress. Therefore, to ensure that asphalt remains in a stable liquid state during transportation, maintains its workability, and meets the requirements of road engineering for material quality and construction continuity, heating and insulation are essential steps.

[0003] The existing asphalt insulation and transportation devices have the following drawbacks: During transportation, the asphalt in the storage tank is in a relatively static state due to gravity, and the asphalt itself has poor fluidity, resulting in low heat conduction efficiency inside the tank. This leads to uneven temperature distribution of the asphalt inside the storage tank. This uneven temperature phenomenon causes some asphalt to increase in viscosity due to excessively low temperature, and may even result in local solidification. In the subsequent unloading process, in order to ensure normal asphalt output, additional heat supply or extended heating time is required. This not only increases energy consumption, but may also cause some asphalt to overheat and deteriorate due to continuous heating, affecting material properties and reducing unloading efficiency. It cannot meet the requirements of engineering construction for the continuity and stability of asphalt transportation. Summary of the Invention

[0004] To address the problem that poor heat conduction when asphalt remains stationary in the storage tank leads to uneven asphalt temperature, requiring the maintenance or even increase of heat supply during subsequent unloading to ensure normal asphalt output, this invention provides an intelligent temperature-controlled asphalt heating and insulation transport vehicle.

[0017] 2. The drive component can drive the tank to rotate axially. The rotation of the tank drives the asphalt to be continuously agitated, so that the asphalt can be in full contact with the circulating heat conduction component during movement. This not only accelerates the uniform conduction of heat, but also prevents the asphalt from increasing in viscosity or even solidifying due to local low temperature. This fundamentally avoids the need for additional heat supply or extended heating time due to asphalt solidification during subsequent unloading, thereby reducing energy consumption and avoiding the risk of asphalt overheating and deterioration due to continuous heating.

[0018] 3. The drive component can also drive the discharge component. While the rotation of the tank keeps the asphalt in good fluidity, it further ensures the smoothness of the asphalt output process, effectively prevents pipeline blockage, greatly improves unloading efficiency, and meets the requirements of road engineering for the continuity and stability of asphalt transportation.

The isolation plane formed by the inclined plates 41 and the arc-shaped pipe 42, together with the tank 3, forms the asphalt dispensing area and the temperature control installation area. The temperature control installation area is filled with heat transfer oil. The obtuse angle design of the partition assembly 4 expands the space of the temperature control installation area, allowing the heat transfer oil to be stored and circulated more fully.

[0029] In a preferred embodiment, the present invention may be further configured as follows: Figure 4 , Figure 5 As shown; the circulating heat conduction component 5 includes: The circulating pump body 51 is fixedly installed on the surface of one of the inclined plates 41 and located in the temperature control installation area. The suction end of the circulating pump body 51 can draw heat transfer oil. A serpentine tube 52 is installed through the inclined plate 41. The number of serpentine tubes 52 is set in two groups, which are respectively set on the two inclined plates 41. The ends of two adjacent serpentine tubes 52 are connected.

[0030] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 2 As shown, an external gear ring 13 is fixedly installed on the outer side of the tank body 3. The drive assembly 6 engages with the external gear ring 13 to drive the tank body 3 to rotate axially. The external gear ring 13 on the outer side of the tank body 3 meshes with the drive assembly 6, and when the drive assembly 6 is working, it drives the tank body 3 to rotate axially. The configuration of the external gear ring 13 provides a stable transmission structure for the rotation of the tank body 3, ensuring that the tank body 3 rotates uniformly.

[0031] In a preferred embodiment, the present invention may be further configured as follows: Figure 6 , Figure 7 As shown; the driving component 6 includes: The drive motor 61 is fixedly installed on the mounting surface of the movable frame 1, and its output end is set parallel to the mounting surface. Mounting cylinder 62 is mounted to the output end of drive motor 61 via a coupling; The movable cap 63 is slidably connected to the inner side of the mounting cylinder 62, and can slide along the inner wall of the mounting cylinder 62. A drive pin 64 is disposed through the mounting cylinder 62 and connected to the movable cap 63. A drive gear 65 is also fixedly installed on the outside of the drive pin 64. A position drive component 66, located inside the mounting cylinder 62, drives the movable cap 63 and the drive pin 64 to move to two different lengths. In one length, the drive gear 65 on the drive pin 64 meshes with the external gear ring 13 to drive the tank body 3 to rotate axially. In the other length, the drive gear 65 on the drive pin 64 is connected to the discharge assembly 7 to output the asphalt from the tank body 3. The drive motor 61 outputs power to the mounting cylinder 62 via a coupling. The movable cap 63 slides within the mounting cylinder 62, driving the drive pin 64 and the drive gear 65 to move. The position drive component 66 can keep the drive gear 65 in two states: when meshing with the external gear ring 13, it drives the tank body 3 to rotate, achieving uniform heating of the asphalt; when meshing with the driven gear 72 of the discharge assembly 7, it drives the discharge assembly 7 to operate and output asphalt. This drive component 66 switches between heating and discharge functions by changing the meshing object of the drive gear 65.

[0032] In a preferred embodiment, the present invention may be further configured as follows: Figure 6 , Figure 7 As shown; the position driving component 66 includes: The first electromagnet 661 is fixedly installed on the inner wall of the mounting cylinder 62; The second electromagnet 662 is fixedly installed on the inner wall of the movable cap 63, wherein the magnetic poles of the first electromagnet 661 and the second electromagnet 662 that are close to each other are the same, so that they repel each other when energized. The connecting column 663 is fixedly installed on the inner side of the mounting cylinder 62, wherein the driving pin 64 is through the connecting column 663 and moves along the axis of the connecting column 663. The elastic element 664 has one end abutting against the inner wall of the movable cap 63, and the other end abutting against the end of the drive pin 64. Two inclined portions 665 are fixedly installed on the inner wall of the movable cap 63, with the inclined surfaces of the two inclined portions 665 being close to each other. The abutment portion 666 is disposed through the connecting post 663 and the drive pin 64. The two ends of the abutment portion 666 contact the inclined portion 665. During displacement, the movable cap 63, through the mutual contact between the inclined portion 665 and the abutment portion 666, drives the drive pin 64 to move to two different lengths. When the first electromagnet 661 and the second electromagnet 662 are energized, they repel each other due to their identical magnetic poles, pushing the movable cap 63 to slide within the mounting cylinder 62. The inclined portion 665 on the inner wall of the movable cap 63 contacts the abutment portion 666, and through the action of the inclined surface, drives the drive pin 64 to move along the connecting post 663 to one state. At this time, the elastic element 6... When 64 is compressed, the drive pin 64 drives the drive gear 65 to accurately switch to a state of meshing with the driven gear 72, thereby realizing the discharge of asphalt. When the first electromagnet 661 and the second electromagnet 662 are not energized, the elastic element 664 drives the movable cap 63 to return to its original state, that is, the first electromagnet 661 and the second electromagnet 662 move closer to each other. At this time, the drive pin 64 drives the drive gear 65 to accurately switch to a state of meshing with the external gear ring 13, thereby driving the tank 3 to rotate. The position driving component 66 realizes the automatic switching of the driving state through the cooperation of electromagnetic force and mechanical structure, ensuring the reliable operation of heating and discharge functions.

[0033] In a preferred embodiment, the present invention may be further configured as follows: Figure 7 , Figure 8 As shown; the abutment part 666 consists of an inclined rod and two inclined abutment members. The two inclined abutment members are fixedly installed on the two ends of the inclined rod. The inclined surfaces of the inclined abutment members are in contact with the inclined surfaces of the inclined part 665. An inclined through hole is opened on the surface of the drive pin 64. An inclined rod is slidably connected in the inclined through hole. The inclined direction of the inclined through hole is the same as the inclined direction of the inclined rod. A displacement hole perpendicular to the axis of the connecting column 663 is opened on the surface of the connecting column 663. The inclined rod and the two inclined abutment members can slide and move in the displacement hole. The inclined rod of the abutment part 666 is slidably connected in the inclined through hole of the drive pin 64. The inclined abutment members at both ends are in contact with the inclined part 665 on the inner wall of the movable cap 63. When the movable cap 63 is displaced, the inclined part 665 pushes the inclined abutment members, causing the inclined rod to slide in the inclined through hole and the displacement hole of the connecting column 663, thereby driving the drive pin 64 to move. This structure ensures the movement path of the drive pin 64 through mechanical transmission via an inclined surface, enabling the drive gear 65 to accurately switch meshing positions.

[0034] In a preferred embodiment, the present invention may be further configured as follows: Figure 3 , Figure 4 As shown; the discharge assembly 7 includes: The auger rod 71 is installed through the tank body 3, and the auger rod 71 is rotatably connected to the tank body 3. A driven gear 72 is fixedly installed on the surface of the auger rod 71 outside the tank body 3, and the driven gear 72 meshes with the driving gear 65. The auger blade 73 is fixedly installed on the outside of the auger rotor 71 and located on the inside of the arc-shaped tube 42; The output cylinder 74 has one end fixedly connected to the end of the arc-shaped tube 42 away from the driven gear 72, and the other end of the output cylinder 74 extends through and to the outside of the tank body 3. The cover 75 is fastened to the end of the output cylinder 74 located outside the tank 3 by fasteners. When the driving gear 65 meshes with the driven gear 72, it drives the auger rod 71 to rotate, and the auger blades 73 rotate accordingly, pushing the asphalt in the asphalt delivery area through the arc-shaped pipe 42 to the output cylinder 74, and then discharging it out of the tank 3 through the output cylinder 74. The cover 75 is used to seal the outlet of the output cylinder 74. Driven by the drive assembly 6, the discharge assembly 7 pushes the asphalt through the rotation of the auger blades 73, ensuring smooth flow of asphalt during the output process.

[0035] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 2 As shown, an insulation layer 14 is fixedly installed on the outside of the tank body 3. The insulation layer 14 is made of one of the following materials: rock wool, glass wool, aluminum silicate fiber, polyurethane foam, or polyphenylene sulfide insulation material. The insulation layer 14 on the outside of the tank body 3 is made of rock wool, glass wool, or other insulation materials, tightly wrapping the tank body 3 to form a heat insulation barrier, reducing heat loss from the tank body to the outside, and maintaining temperature stability in the asphalt delivery area and the temperature control installation area. The installation of this insulation layer 14 can reduce heat loss, avoid the increase in asphalt viscosity due to rapid temperature drop, and at the same time reduce the working time of the electric heating component 53, thus reducing energy consumption.

[0036] The specific working principle of the intelligent temperature-controlled asphalt heating and insulation transport vehicle of the present invention is as follows: First, the mobile frame 1 is connected to the tractor vehicle via the traction unit 2. After being moved to the designated position, the plug 9 of the inlet 8 is opened, and asphalt is added from the inlet 8 into the asphalt delivery area of ​​the tank 3. Then, the plug 9 is used to seal it. The circulating heat transfer component 5 is started, and the circulating pump body 51 draws heat transfer oil from the temperature control installation area. The heat is transferred to the asphalt delivery area through the circulation path of two sets of serpentine tubes 52. The electric heating component 53 heats the heat transfer oil and asphalt. The temperature sensor 54 monitors the temperature of the heat transfer oil in real time and feeds it back to the electric heating component 53 to maintain a constant temperature. The electric heating component 53 and the electrical equipment inside the device can be powered by external wires or brush connectors. The drive components inside the device are all equipped with lubrication oil circuits, and the lubrication mechanism provides the necessary lubrication to the device. Meanwhile, the drive motor 61 of the drive assembly 6 drives the mounting cylinder 62 to rotate. Under the action of the position driving component 66, when the first electromagnet 661 and the second electromagnet 662 are energized and repel each other, the movable cap 63 drives the drive pin 64 to move through the inclined part 665 and the abutment part 666, so that the drive gear 65 meshes with the outer gear ring 13, driving the tank body 3 to rotate axially. At this time, the tank body 3 can rotate axially within the guide frame 10 through the guide pulley 11 in the guide frame 10 and the guide slide 12 on the outside, driving the asphalt to continuously turn over and fully contact the serpentine tube 52 to achieve uniform heating and heat preservation. When material needs to be discharged, the position of the drive component 6 causes the component 66 to be de-energized, the elastic element 664 resets the movable cap 63, the drive gear 65 switches to mesh with the driven gear 72 of the discharge component 7, drives the auger rod 71 to rotate, and the auger blades 73 push the asphalt through the arc tube 42 to the output cylinder 74 for discharge. The cover 75 seals the output cylinder 74 when not in use. During this process, the insulation layer 14 on the outside of the tank 3 continuously blocks heat loss, reduces the working time of the electric heating component 53, reduces energy consumption, and avoids the problem of material blockage caused by the increase in viscosity of asphalt due to temperature drop.

[0037] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
