Description

Technical Field

[0001] The present invention relates to the technical field of cargo pickup passages for refrigerated trucks, and in particular to an isolated cargo pickup passage for refrigerated trucks. Background Art

[0002] In the modern cold chain logistics and transportation system, refrigerated vans play a vital role in safely and efficiently delivering all kinds of temperature-sensitive goods, such as fresh food and medicines, to their destinations. However, traditional refrigerated vans face many problems in the process of picking up goods. On the one hand, frequent opening of the van door to directly pick up goods will cause a large amount of hot air from the outside to quickly rush into the van. Since the goods in the van need to maintain a specific low temperature environment, the entry of hot air from the outside will break the original temperature balance in the van, and it is difficult to restore the temperature to the original set value in a short time, causing the refrigeration system to consume more energy to readjust the temperature, which not only increases energy consumption, but also during this period, the goods in the van that have not been taken out are in an abnormal temperature environment for a long time, greatly increasing the risk of spoilage or deterioration.

[0003] When picking up goods in the existing isolated pickup channels of refrigerated vans, the conventional practice is to open half of the box door and half of the refrigerated truck door. This exposes a large amount of unnecessary pickup space, resulting in a rapid and large loss of cold air. On the one hand, it is difficult to maintain a stable temperature in the van, which greatly increases the risk of goods spoilage and seriously affects the freshness of the goods. On the other hand, the frequent loss of cold air forces the refrigeration equipment to continue to work at a high intensity to restore the temperature, which significantly increases the refrigeration energy consumption and causes energy waste. Moreover, the existing pickup method has a fixed box door size and cannot be flexibly adjusted according to the specifications of the goods. It has poor adaptability to goods of different sizes, which is not conducive to efficient picking and placing of goods, and cannot reduce cold air loss by accurately controlling the door opening space. Overall, it is difficult to meet the requirements of refrigerated transportation for high efficiency, energy saving and cargo quality assurance. Summary of the invention

[0024] Specifically, during use, when it is necessary to take out some of the goods in the truck compartment, the mobile rack 1 is pushed to dock with the rear end of the truck compartment, and then the universal wheels are locked. Then, the half door of the truck compartment is opened, and the conveyor belt 4 protruding at one end of the box body 2 is inserted into the interior of the truck compartment. At this time, the staff enters the interior of the box body 2 through the entrance 11 on one side of the box body 2, and then closes the entrance 11. The interior of the box body 2 is cooled by the cold storage component 3 to ensure the freshness of the goods. The setting of the mobile rack 1 is convenient and flexible to adjust the pickup position. The locking of the universal wheels ensures the stability of the equipment during operation. The conveyor belt 4 is inserted into the truck compartment, which reduces the distance of cargo transportation and reduces labor intensity. The staff enters the independent box body 2 for operation, which is isolated from the truck compartment, reducing the direct loss of cold air in the truck compartment. The cold storage component 3 maintains the low temperature environment of the box body 2 to ensure the freshness of the goods to the greatest extent. Afterwards, the staff starts the driving device of the conveyor belt 4. The conveyor belt 4 is an adjustable telescopic structure, which belongs to the prior art and is not described in detail here. By driving the telescopic structure of the conveyor belt 4, the end inserted into the truck is unfolded, which is convenient for transporting the goods from the inside of the refrigerated truck to the inside of the box body 2, thereby realizing isolated pickup. The conveyor belt 4 starts to transport the goods. When the goods are transported to the area detected by the position sensor 5, the position sensor 5 will transmit the position information of the goods to the control console, and the central control console will start the electrically connected motor 63, which is fixedly connected to the fixed shell 61 through the support plate 62 The fixed shell 61 is fixedly installed with the box body 2, one end of the motor 63 extends into the interior of the fixed shell 61, and the motor 63 drives the gear 64 at the output end to rotate, and the gear 64 is meshed with the rack 1 65 and the rack 2 67, so that the rack 1 65 and the rack 2 67 move in the opposite direction, and the rack 1 65 and the rack 2 67 are slidably connected with the fixed shell 61, and slide in the inside of the notch 611 respectively, and the rack 1 65 and the rack 2 67 respectively drive the connecting plate 1 66 and the connecting plate 2 68 at one end of each to move in the opposite direction, and at the same time, the rack 1 65 and the rack 2 67 respectively drive the slide plate 69 on one side of each side to be fixed with the surface of the box body 2 The slide rail 610 is slidably connected, so that the connecting plate 1 66 and the connecting plate 2 68 respectively drive the cargo door 1 71 and the cargo door 3 77 to slide in the opposite direction. Further, the cargo door 1 71 and the cargo door 3 77 are slidably connected to the surface of the box body 2 through the slider 1 73 and the protrusion 1 75 on one side, so that the spring 74 and the tension spring 76 on one side of the slider 1 73 and the protrusion 1 75 are stretched and stored, and the cargo door 1 71 and the cargo door 3 77 are slidably connected to the cargo door 2 72 and the cargo door 4 78 respectively. As the cargo door 1 71 and the cargo door 3 77 slide, the cargo door 10 is slowly opened. In this way, the refrigerated truck The goods inside are conveyed to the inside of the box 2 through the conveyor belt 4. The adjustable and retractable conveyor belt 4 can adapt to the depth of different truck compartments, enhancing the versatility of the equipment. The linkage between the position sensor 5, the control console and the motor 63 realizes the automatic control of the opening of the incoming door, reduces manual operation, and improves the efficiency of picking up goods. The gear 64 and the rack transmission structure are stable and reliable, and the movement of the incoming door is accurately controlled. The spring 74 and the tension spring 76 are set to buffer the movement of the incoming door 10, reduce mechanical impact, and extend the service life of the equipment. The incoming door 10 opens gradually, reducing the instantaneous loss of a large amount of cold air inside the box 2, and maintaining a good refrigerated environment of the box 2; When the length of the goods is relatively wide, the motor 63 can be continuously driven to rotate, so that the first and third loading doors 71 and 77 respectively push the second and fourth loading doors 72 and 78 to slide to both sides, and the second and fourth loading doors 72 and 78 are respectively slidably connected to the box body 2, and the second and fourth loading doors 72 and 78 slide to both sides to expand the length of the goods entrance. Therefore, the opening size of the loading door 10 can be conveniently adjusted according to the size of the goods, avoiding the need to open both the half door of the box body 2 and the half door of the refrigerated truck to pick up the goods as in the existing picking up method, resulting in the space in the upper half of the half door that is not needed for picking up the goods is also opened, so that the cold air loss of the refrigerated truck and the box body 2 is faster, and the adjustable loading door size greatly improves the adaptability of the equipment to goods of different specifications, and there is no need to open unnecessary loading door space as a whole, which significantly reduces the loss of cold air and reduces the refrigeration energy consumption. While ensuring the smooth picking and placing of goods, the stability of the refrigerated environment is maintained, and the energy utilization efficiency is improved; In addition, a slanted plate 81 is provided on one side of each of the first and third cargo entry doors 71 and 77. The two groups of slanted plates 81 are in an "eight" shape, and the sides of the slanted plates 81 close to the cargo are rotatably connected with rotating rods 82. There are multiple groups of rotating rods 82 distributed at equal intervals. The "eight" shaped slanted plates 81 guide the cargo to smoothly enter the cargo entry door area. The setting of the rotating rods 82 reduces the friction between the cargo and the slanted plates 81, reduces the cargo handling resistance, improves the cargo transportation efficiency, and reduces the wear of the cargo during the handling process, thereby protecting the integrity of the cargo. When the inner surface of the cargo door 1 71 and the cargo door 3 77 is frosted, the cargo door 1 71 and the cargo door 3 77 are easily stuck when closing. Since the cargo door 1 71 and the cargo door 3 77 are provided with a storage slot 1 711 and a storage slot 2 771 inside, and the storage slot 1 711 and the storage slot 2 771 are fixedly installed with a heating wire 1 712 and a heating wire 2 772 inside, the storage slot 1 711 and the storage slot 2 771 are fixedly connected with a cover plate 1 713 and a cover plate 1 Second 773, by starting the heating wire 1 712 and the heating wire 2 772, the surface temperature of the cover plate 1 713 and the cover plate 2 773 is increased, so that the frost is melted. The heating wire defrosting effectively solves the problem of frost jamming of the incoming door, ensures the normal opening and closing of the incoming door 10, avoids the leakage of cold air caused by the inability to close the incoming door 10, maintains a stable low-temperature environment inside the box 2, ensures that the cold and fresh state of the goods is not affected, and reduces the manual defrosting operation, thereby improving the convenience of equipment use; As the motor 63 rotates, the rotating shaft 92 on one side of the belt 1 91 sleeved on the surface will be driven to rotate, and the rotating shaft 92 will drive the driven rod 94 to rotate through the belt 2 93 sleeved on the surface, and the driven rod 94 will drive the round block 96 on the surface of the rotating disk 95 to rotate, and the round block 96 will slide from one end of the hollow plate 97 to the other end, and the hollow plate 97 will drive the push plate 98 to reciprocate, and the push plate 98 is slidably connected to the frame block 910, and the frame block 910 is fixedly connected to the inner wall of the box body 2 through the extension plate 99, and the push plate 98 will drive the scraping plate 911 to reciprocate, and the scraping plate 9 11 is inclined and has two groups symmetrically distributed, with the side away from the push plate 98 in contact with the inner sides of the cargo door one 71 and the cargo door three 77, so that the reciprocating scraping plate 911 will scrape off the frost on the inner sides of the cargo door one 71 and the cargo door three 77, further enhancing the defrosting effect, cooperating with the heating wire to melt the frost, and more thoroughly removing the frost on the inner surface of the cargo door 10, reducing the influence of the accumulation of frost on the sealing and opening and closing smoothness of the cargo door 10, continuously ensuring the normal operation of the equipment, ensuring good refrigeration conditions inside the box body 2, and extending the overall service life of the equipment.
