Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt mixture transportation, in particular to a surface heat preservation covering structure of an asphalt mixture transportation vehicle. Background Art

[0002] The factory temperature of asphalt mixture is generally around 160 degrees. When paving the road, it needs to be transported by bucket trucks. The bucket trucks include a carriage with several rope tighteners installed along the length of the lower ends of the left and right sides of the carriage. The upper opening of the carriage of the bucket truck is exposed to the outside world. Although the asphalt inside the carriage has a good thermal insulation effect, the top layer of asphalt in the carriage is in direct contact with the outside world and has a low temperature, which makes it easy to agglomerate, affecting the molding process during paving.

[0003] CN213743614U discloses a heat-insulating asphalt transport vehicle. The turbocharger assembly is mounted on the engine's exhaust duct assembly. A heat exchanger is mounted on the exhaust duct. The inlet of the heat exchanger is connected to the outlet of the transmission volute via a connecting pipe. An exhaust duct is mounted on the top of the heat exchanger, connecting to the underside of an exhaust hood. A sealing hood is mounted on the top of the vehicle's sealing cover. A cavity is defined between the sealing hood and the sealing cover. An exhaust port is located on the right side of the exhaust hood, facing the left end of the cavity. Heat from the engine exhaust duct heats the air, blowing the hot air into the cavity at the top of the vehicle. This results in a higher temperature at the top of the vehicle, better insulation for the asphalt inside the vehicle, and prevents the top layer of asphalt from agglomerating. This technical solution utilizes a sealing hood mounted on the top of the vehicle to cover the upper layer of asphalt mixture. However, asphalt mixture is typically discharged directly downward after mixing at an asphalt mixing plant, making this arrangement more cumbersome during loading and affecting loading efficiency.

[0004] Based on the deficiencies in the existing technology, the utility model discloses a surface insulation covering structure for an asphalt mixture transport vehicle. By arranging a covering cloth that is easy to disassemble and install at the upper opening of the vehicle compartment, the covering cloth is connected to the vehicle compartment through a number of woven belts, thereby reducing the direct contact between the upper asphalt layer and the outside world, achieving a certain insulation effect on the upper surface of the asphalt, and facilitating loading and unloading.

[0026] See also Figure 1-5 As shown, a surface insulation covering structure of an asphalt mixture transport vehicle includes a covering cloth 2 for covering the upper compartment opening of a compartment 1. The covering cloth 2 is a Teflon-coated glass fiber cloth. The length direction of the covering cloth 2 is arranged along the length direction of the compartment 1. The lower end surface of the covering cloth 2 is provided with a woven belt 3 along its width direction. The two ends of the woven belt 3 are respectively provided with connectors 4 for connecting to the compartment rope tightener 5. The left and right ends of the woven belt 3 are located at the upper ends of the left and right side walls of the compartment 1 and are respectively provided with inverted U-shaped lap joints 6. A plurality of woven belts 3 are provided, and the plurality of woven belts 3 are arranged in sequence along the length direction of the covering cloth 2. Teflon-coated glass fiber cloth can withstand long-term use in a wide temperature range of -60°C to +300°C. It can withstand temperatures as high as +360°C for 120 hours without aging or cracking, maintaining excellent flexibility. Pastes, adhesive resins, organic coatings, asphalt mixtures, and nearly all other sticky substances can be easily removed from the surface of PTFE-coated high-temperature cloth. The surface of PTFE-coated high-temperature cloth withstands a compressive load of 200kg / cm² with virtually no deformation or loosening. It exhibits an exceptionally low coefficient of friction, excellent dimensional stability, and a tensile elongation of ≤5%. PTFE-coated high-temperature cloth possesses unique electrical insulation properties, with a dielectric constant of 2.6 and a dielectric loss tangent below 0.0025. It is resistant to corrosion from nearly all chemicals and substances. PTFE-coated high-temperature cloth remains stable in strong acid and alkali conditions, without aging or deformation. Therefore, by setting a covering cloth that is easy to disassemble and install at the upper opening of the carriage, the covering cloth is connected to the carriage through several woven belts, which reduces the direct contact between the upper asphalt and the outside world, achieves a certain insulation effect on the upper surface of the asphalt, and facilitates loading and unloading.

[0027] The inverted U-shaped lap joint 6 includes a horizontal lap joint 61 for contacting the upper end surface of the side wall of the car body 1, an inner vertical plate 62 for contacting the inner side of the side wall of the car body 1, and an outer vertical plate 63 for contacting the outer side of the side wall of the car body 1. The upper ends of the inner vertical plate 62 and the outer vertical plate 63 are respectively connected to the lower end surface of the horizontal lap joint 61. The longitudinal direction of the horizontal lap joint 61 is arranged along the longitudinal direction of the car body 1. The upper end surface of the horizontal lap joint 61 is connected to the lower end surface of the woven belt 3, and the left and right ends of the upper end surface of the horizontal lap joint 61 have rounded corners. The rounded corners of the horizontal lap joint 61 reduce the friction of the edges of the horizontal lap joint 61 on the woven belt 3 and the corners of the covering cloth 2 when the woven belt is in contact.

[0028] The length of the horizontal buttress 61 is not less than the width of the braided belt 3 .

[0029] The thickness of the inner vertical plate 62 is smaller than that of the outer vertical plate 63. The longitudinal length of the inner vertical plate 62 is greater than that of the outer vertical plate 63. The lower end of the inner vertical plate 62 is set at a sharp angle. The sharp angle of the inner vertical plate 62 facilitates insertion into the vehicle compartment filled with asphalt mixture.

[0030] The length direction of the braided belt 3 is arranged along the width direction of the covering cloth 2, and the length of the braided belt 3 is greater than the width of the covering cloth 2. The braided belt 3 is made of Teflon-coated glass fiber cloth strips. The upper end surface of the braided belt 3 is sewn with the lower end surface of the covering cloth 2.

[0031] The upper end surface of the braided belt 3 is also provided with a heat-insulating layer. The heat-insulating layer is made of heat-insulating and flame-retardant cloth, which further improves the heat preservation effect of the upper asphalt layer.

[0032] The covering cloth 2 is double-layered, and a heating wire is arranged between the two covering cloths 2. The heating wire is evenly distributed in a snake shape along the length direction of the covering cloth 2. The power supply of the heating wire is obtained from the battery of the transport vehicle.

[0033] The connector 4 includes a first rope 41 and a second rope 42. The upper ends of the first and second ropes 41 and 42 are connected to the two corners of the braided belt 3. The lower ends of the first and second ropes 41 and 42 are connected to a third rope 43, which is connected to the car body rope tensioner 5. The first and second ropes 41 and 42 are of the same length, forming an equilateral triangle with the ends of the braided belt 3. The rope tensioner 5 secures the braided belt 3 by tightening the third rope 43. The arrangement of the first and second ropes 41 and 42 improves the uniformity of force applied to the braided belt 3.

[0034] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
