Description

Technical Field

[0001] This utility model relates to the technical field of road engineering materials and construction equipment, and in particular to a heat preservation device for transporting SBS modified asphalt mixture. Background Technology

[0002] In the field of road construction, SBS modified asphalt mixture has become a commonly used material for road paving due to its good high-temperature stability and low-temperature crack resistance. However, the temperature of asphalt mixture needs to be strictly controlled during transportation to ensure its paving and compaction performance. Therefore, there are high requirements for the insulation effect and unloading efficiency of the transportation insulation device.

[0003] When the asphalt mixture is transported and the insulation device is unloading, the bottom unloading door of the insulation tank is opened first. The mixture slides out along the inclined bottom plate under the action of gravity. At the same time, the mixing blades rotate slowly to prevent segregation. The temperature control system continuously monitors the temperature of the remaining material. After unloading is completed, the hatch is closed in time to maintain the insulation state of the tank, ensuring that the unloading process is continuous and the temperature loss is controllable.

[0004] The existing technology has the following drawbacks: Existing asphalt mixture transport insulation devices rely heavily on manual operation during unloading, resulting in a lack of smooth transition between unloading and paving operations, leading to low construction efficiency. Furthermore, the sealing structure of the inlet is poorly designed, requiring workers to directly contact the high-temperature area for sealing operations after loading, posing a risk of burns from hot gases. Additionally, the sealing effect is poor, making it difficult to guarantee the insulation performance of the insulation box. Therefore, an SBS modified asphalt mixture transport insulation device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an SBS modified asphalt mixture transportation insulation device, which aims to improve the low efficiency of manual unloading in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat preservation device for transporting SBS modified asphalt mixture, comprising a bearing plate, a hydraulic rod provided on the inner wall of the bearing plate via a bracket, a heat preservation box fixedly connected to the inner wall of the bearing plate, a baffle hinged to the inner wall of the heat preservation box, an inclined block fixedly connected to the inner wall of the heat preservation box, a slider slidably connected to the inner wall of the bearing plate, a feed inlet fixedly connected to the top of the heat preservation box, a sealing plug contacting the top of the feed inlet, a movable mechanism provided at the top of the slider, and an opening and closing assembly provided at the top of the heat preservation box; The movable mechanism includes a fixed block, which is fixedly connected to the top of the slider, and a movable plate is hinged to the inner wall of the fixed block via a hinge rod.

[0007] As a further description of the above technical solution: The opening and closing assembly includes a connecting rod, which is rotatably connected to the top of the insulated box. The inner wall of the front end of the connecting rod is elastically connected to a locking block by a movable spring.

[0008] As a further description of the above technical solution: The top of the slider is in contact with the bottom of the baffle.

[0009] As a further description of the above technical solution: The sidewall of the baffle is in contact with the sidewall of the inclined block, and the inclined block is triangular.

[0010] As a further description of the above technical solution: The movable plate is slidably connected to the inner wall of the support plate.

[0011] As a further description of the above technical solution: The sealing plug is fixedly connected to the right end of the connecting rod, and the movable plate is fixedly connected to the movable end of the hydraulic rod.

[0012] As a further description of the above technical solution: The inner wall of the support plate has a rectangular opening.

[0013] As a further description of the above technical solution: The locking block is engaged with the top of the insulated box, and the locking block is slidably connected to the inner wall of the connecting rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the slider and the baffle are driven by an electro-hydraulic rod, and the asphalt itself is used to achieve automatic asphalt unloading and automatic baffle closure. When combined with the road roller behind the transport vehicle, the unloading and paving operations can be completed efficiently, improving construction efficiency.

[0015] 2. In this utility model, the combination of a locking block, a movable spring and a sealing plug is used to achieve rapid opening and sealing of the feed inlet. After the material is fed, the worker does not need to directly contact the high-temperature area, avoiding burns from high-temperature gas when the sealing plug is closed, ensuring the safety of the worker's operation, and at the same time ensuring the sealing and heat preservation effect of the heat preservation box.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of an SBS modified asphalt mixture transportation insulation device, comprising a support plate 1, which is installed on a transport vehicle and can move with the vehicle to a designated location. A hydraulic rod 2 is mounted on the inner wall of the support plate 1 via a bracket. The hydraulic rod 2 is a mechanical device that uses liquid (usually hydraulic oil) as the working medium and transmits energy through liquid pressure to achieve linear reciprocating motion or support function. An insulation box 3 is fixedly connected to the inner wall of the support plate 1. Two sets of baffles 5 are hinged to the inner wall of the insulation box 3, serving to shield the asphalt material. An inclined block 11 is fixedly connected to the inner wall of the insulation box 3. When the baffle 5 is opened, the asphalt on the inclined block 11 falls under gravity. A slider 4 is slidably connected to the inner wall of the support plate 1. The plate 1 has a slot corresponding to the slider 4, allowing the slider 4 to move left and right. The top of the insulation box 3 is fixedly connected to the feed inlet 9, and the top of the feed inlet 9 contacts the sealing plug 10. When the sealing plug 10 and the feed inlet 9 are closed, they seal the device. The top of the slider 4 is provided with a movable mechanism, and the top of the insulation box 3 is provided with an opening and closing assembly. The movable mechanism includes a fixed block 6, which is fixedly connected to the top of the slider 4. The inner wall of the fixed block 6 is hinged to a movable plate 8 through a hinge rod 7. Since the length of the hinge rod 7 is fixed, when the movable plate 8 moves downward with one end of the hinge rod 7, the other end of the hinge rod 7 will cause the two sets of sliders 4 to separate from each other. When the movable plate 8 moves upward with one end of the hinge rod 7, the other end of the hinge rod 7 will cause the two sets of sliders 4 to move closer together.

[0020] Reference Figure 1 , Figure 4 and Figure 5 The opening and closing assembly includes a connecting rod 12, which is rotatably connected to the top of the insulation box 3. The insulation box 3 has a slot corresponding to the connecting rod 12 to facilitate the rotation of the connecting rod 12. The inner wall of the front end of the connecting rod 12 is elastically connected to a locking block 13 via a movable spring 14. When the locking block 13 moves forward, the movable spring 14 is compressed. When resetting, the elastic force of the movable spring 14 drives the locking block 13 to reset. The locking block 13 is locked onto the top of the insulation box 3 and is slidably connected to the inner wall of the connecting rod 12. The connecting rod 12 has a slot corresponding to the locking block 13, allowing the locking block 13 to move back and forth.

[0021] Reference Figures 1-3The top of the slider 4 contacts the bottom of the baffle 5, and the slider 4 acts as a shield and limiter for the baffle 5. The side wall of the baffle 5 contacts the side wall of the inclined block 11. When the baffle 5 contacts the inclined block 11, the device is in a sealed state. The inclined block 11 is triangular. The moving plate 8 is slidably connected to the inner wall of the bearing plate 1. The bearing plate 1 has a slot corresponding to the moving plate 8, so that the moving plate 8 can move vertically. The sealing plug 10 is fixedly connected to the right end of the connecting rod 12. The moving plate 8 is fixedly connected to the movable end of the hydraulic rod 2. The inner wall of the bearing plate 1 has a rectangular opening, so that the asphalt material can fall from the opening.

[0022] Working principle: When unloading is required, the externally controlled hydraulic rod 2 moves downward, which moves the moving plate 8 and the hinge rod 7 downward. The other end of the hinge rod 7 separates the two sets of sliders 4. When the sliders 4 do not block the baffle 5, the gravity of the asphalt material will squeeze the two sets of baffles 5 to flip open. At this time, the asphalt material will fall from the opening of the baffle 5. The road roller following behind the transport vehicle can flatten the falling asphalt. When all the asphalt material has fallen, the externally controlled hydraulic rod 2 moves upward, which moves the moving plate 8 and one end of the hinge rod 7 upward. The other end of the hinge rod 7 brings the two sets of sliders 4 closer together. The sliders 4 squeeze the baffle 5 to flip inward and close. When the sliders 4 move to the initial position, the baffle 5 is completely closed.

[0023] When feeding is required, manually move the locking block 13 forward. The locking block 13 will compress the movable spring 14. When the locking block 13 separates from the slot on the insulation box 3, manually rotate the connecting rod 12 and the locking block 13 counterclockwise. When the connecting rod 12, along with the sealing plug 10, no longer blocks the feed inlet 9, the locking block 13 will coincide with the slot on the insulation box 3. Manually release the locking block 13, and use the elasticity of the movable spring 14 to engage the locking block 13 into the slot on the insulation box 3. When feeding is complete, manually move the locking block 13 forward. When the locking block 13 separates from the slot on the insulation box 3, manually rotate the connecting rod 12 and the sealing plug 10 clockwise. When the sealing plug 10 blocks the feed inlet 9, the locking block 13 will coincide with the slot on the insulation box 3. Manually release the locking block 13, allowing the locking block 13 to engage into the slot on the insulation box 3, thus completing the limiting of the sealing plug 10.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
