Description

Technical Field

[0001] This application relates to the field of semi-trailer boxes, and more particularly to a box-type semi-trailer box that can be automatically loaded and unloaded. Background Technology

[0002] The main function of a semi-trailer is to provide cargo loading space and load-bearing capacity. It relies on the traction power provided by the tractor in front to move. A semi-trailer is a type of vehicle that has no driving ability of its own. Its design allows for a certain degree of relative freedom of movement between the trailer and the main vehicle. This flexibility allows semi-trailers to adapt to various transportation needs, such as container transportation and bulk cargo transportation.

[0003] However, traditional semi-trailer trucks require a large number of workers to manually handle some goods, which consumes a lot of physical strength and increases labor costs. At the same time, manual handling is slow, and heavy items are easy to slip from the hands due to exhaustion, resulting in poor loading and unloading efficiency and safety. Utility Model Content

[0004] In order to improve loading and unloading speed, save labor costs and improve safety during loading and unloading, this application provides an automatically loading and unloading box semi-trailer.

[0005] The present application provides an automatically loading and unloading box-type semi-trailer body, which adopts the following technical solution: An automatically loading and unloading box-type semi-trailer includes a box body with a loading and unloading structure. The loading and unloading structure includes guide rails and sliders. Two guide rails are fixedly connected to the box body, and two sliders are slidably connected to the guide rails. A common rotating shaft is rotatably connected between the two sliders on the two guide rails. A locking block is fixedly connected to the rotating shaft, and one end of the locking block engages with the guide rail. A support plate is slidably connected to the rotating shaft, and a connecting frame is fixedly connected to the support plate. Two rollers are rotatably connected to the connecting frame, and a common conveyor belt is wound around the two rollers. A motor is installed on the connecting frame, and the output shaft of the motor is fixedly connected to one of the rollers.

[0006] By adopting the above technical solution, pulling the rotating shaft causes two sliders to slide on the guide rail. As the rotating shaft moves, the locking block will not engage with the guide rail, allowing the rotating shaft to be rotated. The rotating shaft will then rotate the support plate, which in turn will rotate the connecting frame. When one end of the connecting frame touches the ground, the rotating shaft will not rotate. Then, by connecting the power supply and starting the motor, the motor's output shaft will rotate, driving one of the rollers to rotate. The rotation of the roller will then drive the conveyor belt to rotate. At this point, the goods to be loaded and unloaded only need to be placed on the conveyor belt to achieve automatic loading and unloading, thus avoiding the need for workers to spend a lot of time and effort handling goods. This effectively improves the efficiency of loading and unloading goods. Furthermore, after a portion of the goods in the carriage has been loaded and unloaded, the support plate can be pushed to slide on the rotating shaft, thereby changing the position of the conveyor belt. This facilitates loading and unloading goods at different positions in the carriage, effectively improving the flexibility of use.

[0007] Optionally, a first knob is threaded onto the slider, and two first slots are provided on the guide rail, with one end of the first knob engaging with one of the first slots.

[0008] By adopting the above technical solution, the slider can be limited by the engagement between the first knob and the first slot, so that the slider cannot slide on the guide rail. At this time, since the locking block is engaged with the guide rail, the rotating shaft cannot rotate, which makes it easier to collect the conveyor belt.

[0009] Optionally, the rotating shaft is provided with a plurality of second slots, and a second knob is threadedly connected to the support plate, with one end of the second knob engaging with one of the second slots.

[0010] By adopting the above technical solution, when the position of the support plate on the rotating shaft changes, the second knob can engage with the second slot to prevent the support plate from moving during installation and removal, thereby effectively improving the stability of use. Optionally, the cross-sections at both ends of the rotating shaft are circular, and the cross-section in the middle of the rotating shaft is rectangular.

[0011] By adopting the above technical solution, it is possible to rotate between the rotating shaft and the slider, while avoiding rotation between the support plate and the rotating shaft.

[0012] Optionally, two connecting shafts are rotatably connected to the carriage body, and door panels are fixedly connected to the connecting shafts.

[0013] By adopting the above technical solution, after the goods are loaded and unloaded, the goods can be shielded and protected by two door panels to prevent them from being exposed to the air for a long time during transportation and thus being damaged.

[0014] Optionally, the two door panels are symmetrically distributed about the middle of the carriage body, and the overall cross-section of the door panels is L-shaped.

[0015] By adopting the above technical solution, it is possible to avoid the carriage body obstructing the door panel during the rotation process.

[0016] Optionally, the carriage body is provided with an opening and closing structure, which includes a guide sleeve and a slide rod. Two guide sleeves are fixedly connected to the carriage body, and the same slide rod is slidably connected to the two guide sleeves. Two racks are fixedly connected to both ends of the slide rod, and a gear is fixedly connected to one end of the connecting shaft. The racks mesh with adjacent gears.

[0017] By adopting the above technical solution, when it is necessary to open the door panel, the sliding rod can be moved. The movement of the sliding rod will drive the two racks to move. Since the two racks are located on both sides of the two gears, when the two racks move in the same direction, the two gears will rotate in opposite directions. The rotation of the gears in opposite directions will drive the connecting shaft to rotate, and the rotation of the connecting shaft will drive the door panel to rotate, thereby opening the two door panels. After the door panels are opened, it is convenient to load and unload goods.

[0018] Optionally, an electric push rod is installed on the carriage body, and the extended end of the electric push rod is fixedly connected to the slide rod.

[0019] By adopting the above technical solution, it is possible to drive the slide bar to move by activating the electric push rod.

[0020] In summary, this application includes at least one of the following beneficial technical effects: When loading and unloading goods is required, one end of the connecting frame can be placed on the ground. Then, the goods to be loaded and unloaded can be placed on the conveyor belt, and the goods can be automatically loaded and unloaded by the movement of the conveyor belt. This avoids the need for staff to spend a lot of time and effort to handle the goods, and effectively improves the efficiency of loading and unloading goods. After a portion of the cargo in the carriage is loaded or unloaded, the support plate can be pushed to slide on the rotating shaft, thereby changing the position of the conveyor belt. This facilitates loading and unloading of cargo at different positions in the carriage, effectively improving the flexibility of use. When loading and unloading goods is not required, the conveyor belt can be stowed away, thereby reducing space occupation and facilitating the movement of the semi-trailer.

[0023] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0024] This application discloses an automatically loading and unloading box-type semi-trailer. (Refer to...) Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 An automatically loading and unloading box-type semi-trailer includes a box body 1, on which a loading and unloading structure 4 is provided.

[0025] Rotating the first knob 403 will cause it to move away from the first slot 404. Continue rotating the first knob 403 until its end disengages from the first slot 404. Repeat the above operation until all the first knobs 403 are no longer engaged with the first slots 404. Then, pull the rotating shaft 405. The rotating shaft 405 will drive the two sliders 402 to slide on the guide rail 401. As the rotating shaft 405 moves, the locking block 406 will no longer engage with the guide rail 401. Then, rotate the rotating shaft 405. The rotating shaft 405 will drive the support plate 407 to rotate together. The support plate 407 will drive the connecting frame 408 to rotate. When the connecting frame 408... When one end of the slider touches the ground, push the slider 402 in the opposite direction to reset it. Then rotate the first knob 403 in the opposite direction to engage the end with the first slot 404. At this time, the shaft 405 will not be able to move. Then, the power can be turned on and the motor 411 can be started. The output shaft of the motor 411 rotates and drives one of the rollers 409 to rotate. The rotation of one of the rollers 409 will drive the conveyor belt 410 to rotate. At this time, the goods to be loaded and unloaded can be placed on the conveyor belt 410 to achieve automatic loading and unloading of goods, thereby avoiding the need for workers to spend a lot of time and effort to handle goods and effectively improving the efficiency of loading and unloading goods. After a portion of the cargo in the carriage body 1 has been loaded or unloaded, the second knob 412 can be rotated. Since the second knob 412 and the support plate 407 are threaded together, as the second knob 412 rotates, its end will not engage with one of the second slots 413. Then the support plate 407 can be pushed to slide on the rotating shaft 405. The movement of the support plate 407 will drive the connecting frame 408 and the conveyor belt 410 to move together, thereby changing the position of the conveyor belt 410. After the position of the conveyor belt 410 is changed, it is convenient to load and unload cargo at different positions of the carriage body 1, thereby effectively improving the flexibility of use. When loading and unloading are not required, the two door panels 3 can be closed first, and then the conveyor belt 410 can be rotated towards the door panels 3. When the conveyor belt 410 approaches the door panel 3, the end of the locking block 406 will be facing the guide rail 401. Then the rotating shaft 405 can be pushed. The rotating shaft 405 drives the two sliders 402 to slide on the two guide rails 401 respectively. The movement of the sliders 402 will drive the locking block 406 to move. When the locking block 406 is engaged with the guide rail 401, the first knob 403 can be rotated to engage it with the first slot 404. At this time, the sliders 402 will not be able to move. At the same time, since the locking block 406 is engaged with the guide rail 401, the rotating shaft 405 will not be able to rotate, thus realizing the storage of the conveyor belt 410, thereby reducing the space occupied and facilitating the movement of the semi-trailer.

[0026] Reference Figure 1 , Figure 2 and Figure 5Two guide sleeves 501 are fixedly connected to the carriage body 1. The same slide rod 502 is slidably connected to the two guide sleeves 501. Two racks 503 are fixedly connected to both ends of the slide rod 502. A gear 504 is fixedly connected to one end of the connecting shaft 2. The racks 503 mesh with the adjacent gears 504. An electric push rod 505 is installed on the carriage body 1. The extended end of the electric push rod 505 is fixedly connected to the slide rod 502.

[0027] When it is necessary to open the door panel 3, the electric push rod 505 can be activated. The electric push rod 505 extends and drives the slide rod 502 to move. Two guide sleeves 501 are set to guide the movement of the slide rod 502. The movement of the slide rod 502 will drive the two racks 503 to move. Since the two racks 503 are located on both sides of the two gears 504, when the two racks 503 move in the same direction, the two gears 504 will rotate in opposite directions. The reverse rotation of the gears 504 will drive the connecting shaft 2 to rotate. The rotation of the connecting shaft 2 will drive the door panel 3 to rotate, thereby opening the two door panels 3. After the door panels 3 are opened, it is convenient to load and unload goods.

[0028] This application discloses an implementation principle of an automatically loading and unloading box semi-trailer: when loading and unloading goods is required, the first knob 403 can be rotated continuously until its end disengages from the first slot 404. This operation is repeated until all the first knobs 403 are no longer engaged with the first slots 404. Then, the rotating shaft 405 can be pulled, causing two sliders 402 to slide on the guide rail 401. As the rotating shaft 405 moves, the locking block 406 will no longer engage with the guide rail 401. Then, the rotating shaft 405 can be rotated, causing the support plate 407 to rotate as well. The support plate 407 then causes the connecting frame 408 to rotate. When one end of the connecting frame 408 touches the ground, it pushes the slider in the opposite direction. Block 402 is reset, and then the first knob 403 is rotated in the opposite direction to engage its end with the first slot 404. At this time, the rotating shaft 405 will not be able to move. Then the electric push rod 505 can be activated. The electric push rod 505 extends and drives the slide rod 502 to move. The movement of the slide rod 502 will drive the two racks 503 to move. Since the two racks 503 are located on both sides of the two gears 504, when the two racks 503 move in the same direction, the two gears 504 will rotate in opposite directions. The reverse rotation of the gears 504 will drive the connecting shaft 2 to rotate. The rotation of the connecting shaft 2 will drive the door panel 3 to rotate, thereby opening the two door panels 3. Then the power can be turned on and the motor 411 can be started. The output shaft of the motor 411 rotates and drives one of the roller shafts 409 to rotate. One of the rollers 409 rotates, driving the conveyor belt 410 to rotate. At this point, the goods to be loaded or unloaded only need to be placed on the conveyor belt 410 to achieve automatic loading and unloading, thus avoiding the need for workers to spend a lot of time handling goods and effectively improving the efficiency of loading and unloading. After a portion of the goods in the carriage body 1 has been loaded or unloaded, the second knob 412 can be rotated. Because the second knob 412 and the support plate 407 are threaded together, as the second knob 412 rotates, its end will not engage with one of the second slots 413. Then, the support plate 407 can be pushed to slide on the rotating shaft 405. The movement of the support plate 407 will drive the connecting frame 408 and the conveyor belt 410 to move together, thereby achieving automatic loading and unloading. By changing the position of conveyor belt 410, loading and unloading of goods at different locations on the carriage body 1 can be facilitated, thus effectively improving the flexibility of use. When loading and unloading of goods is not required, the two door panels 3 can be closed first, and then the conveyor belt 410 can be rotated towards the door panels 3. When the conveyor belt 410 approaches the door panel 3, the end of the locking block 406 will be aligned with the guide rail 401, and then the rotating shaft 405 can be pushed. The rotating shaft 405 drives the two sliders 402 to slide on the two guide rails 401 respectively. The movement of the sliders 402 will drive the locking block 406 to move. When the locking block 406 is engaged with the guide rail 401, it can be engaged with the first slot 404 by rotating the first knob 403. At this time, the slider 402 will not be able to move.Simultaneously, because the locking block 406 engages with the guide rail 401, the rotating shaft 405 cannot rotate, thus achieving the storage of the conveyor belt 410, reducing space occupation and facilitating the movement of the semi-trailer.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
