Technical Field

[0001] The utility model relates to the technical field of soil trucks, in particular to an asphalt concrete truck with a semi-canvas-lifting mechanism. Background Art

[0002] For asphalt pavements, temperature not only directly affects the workability of the mixture during construction, but also is closely related to the long-term service performance of the asphalt pavement after the asphalt mixture is paved. It is found in actual construction that the heat preservation measures during the transportation of asphalt mixtures are often unsatisfactory. Especially when the distance between the asphalt mixing plant and the construction site is far, vehicle breakdowns occur during transportation, unexpected rainfall occurs, or construction is carried out in cold weather in autumn and winter, the temperature of the arriving asphalt mixture may be lower than the requirement, resulting in difficulty in compressing the mixture and causing early disease problems such as potholes or ruts after the pavement is formed.

[0003] To solve the above problems, engineers cover a layer of canvas on the top of the carriage of the transport truck to maintain a certain temperature inside the carriage; however, before loading and unloading, it is necessary to manually climb the carriage to lift the canvas, which is likely to pose a safety hazard to the driver and cause inconvenience to transportation. Therefore, we have improved the above existing technology according to the actual usage situation. Summary of the Utility Model

[0024] As Figures 1 to 6 shown, the embodiment of the present invention provides an asphalt concrete truck with a semi-canvas-lifting mechanism, which includes a vehicle body 1. The periphery of the carriage of the vehicle body 1 is covered with a canvas 2, and a canvas lifting assembly 3 is arranged at the tail end of the canvas 2; the canvas lifting assembly 3 includes a longitudinal rod 31 and a transverse rod 32. The transverse rod 32 is integrally arranged between the two longitudinal rods 31, and the two longitudinal rods 31 are rotatably arranged on the front and rear sides of the vehicle body 1

[0025] A driving mechanism is provided at the front side of the carriage of the vehicle body 1, and the driving mechanism consists of a first self-locking motor 7 and a first gear 8. The first self-locking motor 7 is fixed to the front side of the carriage of the vehicle body 1, and the output end of the first self-locking motor 7 fixes the first gear 8 through a rotating shaft; two longitudinal rods 31 are installed at the 1 / 4 position of the carriage length. A second gear 35 is fixed to the front side of one of the longitudinal rods 31. The second gear 35 meshes with the first gear 8 to drive the longitudinal rod 31 to rotate. Connecting shafts 36 are fixed to the inner sides of the two longitudinal rods 31, and one end of each connecting shaft 36 is rotatably connected to the carriage of the vehicle body 1 through a bearing. A sleeve 33 is sleeved around the outer periphery of the cross bar 32, and a cloth pull 34 is fixed to the outer surface of each sleeve 33 through a rivet. The upper end of the cloth pull 34 is fixed to the inner side of the tail end of the canvas 2 through a rivet. A humidity sensor 5, an electric heater 6 and a temperature sensor 9 are arranged on the lower surface of the canvas 2 to monitor the surface temperature of the mixture in real time. When it is found that the material temperature is significantly lower than the set value, the electric heater 6 is started to heat the mixture; this device can monitor the surface temperature of the mixture in real time during the transportation of the mixture and automatically heat it, and the temperature of the mixture can be maintained for a long time; the initial set value can be set between 30-90 degrees; the electric heater 6 is an electric heating wire;

[0026] Reference Figure 2 and Figure 3 , the tail end of the canvas 2 is fixed 10 cm behind the extension of the cross bar 32. A tightening assembly 4 is arranged at the extended end of the canvas 2. The tightening assembly 4 consists of a second self-locking motor 43, a pulley 41 and a tightening rope 42. The second self-locking motor 43 is fixed to the front side of one of the longitudinal rods 31, and the output end of the second self-locking motor 43 fixes the pulley 41 through a rotating shaft; the tightening rope 42 passes through the extended end of the canvas 2, one end of the tightening rope 42 is wound around the pulley 41, and the other end of the tightening rope 42 is fixed to the longitudinal rod 31 located at the rear side of the carriage through a rivet. A controller is arranged in the driver's cab of the vehicle body 1 to control the driving mechanism and the tightening assembly 4. The canvas 2 is allowed to naturally droop to the tail end of the carriage to complete the covering of the carriage; to reduce the temperature loss during the transportation of the material, the second self-locking motor 43 is started to drive the pulley 41 to rotate, and by tightening the tightening rope 42, the tail end of the canvas 2 is tightly fixed to the tail of the carriage, which is beneficial to maintaining the temperature of the asphalt in the carriage;

[0027] Working principle: After the transport vehicle is filled with the mixed asphalt mixture, the canvas 2 is covered on the top surface of the carriage; to ensure the heat preservation effect of the transport vehicle, the first self-locking motor 7 is started to drive the first gear 8 to rotate, and the longitudinal rod 31 and the cross bar 32 are lowered, so that the canvas 2 naturally droops to the tail end of the carriage to complete the covering of the carriage; to reduce the temperature loss during the transportation of the material, the second self-locking motor 43 is started to drive the pulley 41 to rotate, and by tightening the tightening rope 42, the tail end of the canvas 2 is tightly fixed to the tail of the carriage;

[0028] When carrying out the paving construction of the asphalt pavement, first start the second self-locking motor 43 to relax the tightening rope 42, and then start the first self-locking motor 7 to drive the first gear 8 to rotate, lifting the longitudinal rod 31 and the transverse rod 32, so that the canvas 2 is folded and stacked on the top surface of the carriage, exposing 1 / 4 of the top surface area of the carriage for the dumping of the mixture and observing the dumping condition of the mixture during the construction process. Keep this state until the mixture is completely unloaded;

[0029] During the transportation of the material, the temperature sensor 9 arranged on the canvas 2 monitors the surface temperature of the mixture in real time. When it is found that the material temperature is significantly lower than the set value, start the electric heating 6 to heat the mixture; this device can monitor the surface temperature of the mixture in real time during the transportation of the material and automatically heat it, maintaining the temperature of the mixture for a long time; it has a high degree of automation, reduces the poor effect of the traditional driver of the material transport vehicle manually lifting the cloth, reduces the risk of the driver falling when climbing up and down, and has a high practical value, which is conducive to large-scale promotion and is applicable to all material transport vehicles.
