Abstract
Description
Technical Field
[0001] This application relates to the fields of transportation and cargo handling, and particularly to a support device for a self-unloading semi-trailer. Background Art
[0002] In the transportation industry, especially in the logistics link involving cargo handling, self-unloading semi-trailers have always played an indispensable key role. In recent years, with the acceleration of the global economic integration process, the logistics industry has迎来了前所未有的快速发展期. The connections between various industries have become increasingly close, the scale of material circulation has continued to expand, and the demand for efficient cargo handling and safe transportation has shown a sharp growth trend. Self-unloading semi-trailers,凭借其能够实现货物自动卸载的显著优势,极大地提高了装卸效率,大幅减少了人力成本的投入. This characteristic has significantly accelerated the turnover speed of goods and strongly promoted the efficient operation of the entire logistics industrial chain.
[0003] To achieve the cargo unloading function of self-unloading semi-trailers, the prior art usually采用倾斜货箱的方式,利用货物自身的重力实现下滑卸载. This method is relatively direct. It is借助液压系统将货箱的一端缓缓抬起,使货箱形成一定的倾斜角度,此时货物便会在重力的作用下沿着货箱表面自然滑落. In actual operation, this method is relatively simple and the equipment cost is relatively low, but it is necessary to ensure the sealing and stability of the cargo box to prevent cargo leakage or damage during the tilting process.
[0004] Regarding the above related technologies, when encountering goods of different shapes, weights, and properties, it is often difficult to achieve an ideal unloading effect. It is impossible to well control the unloading direction and speed of the goods, and situations such as uneven cargo accumulation or spilling may occur. Uneven cargo accumulation will not only increase the workload of subsequent sorting and handling, but also,由于不能精确控制卸载过程,还可能导致货物在卸载过程中受到损坏,增加了运输成本. Therefore, there is an urgent need for a support device for a self-unloading semi-trailer to solve the above problems. Summary of the Invention
[0005] To solve the above problems, this application provides a support device for a self-unloading semi-trailer.
[0006] The support device for a self-unloading semi-trailer provided by this application采用如下的技术方案: It should be noted that there are some Chinese expressions in the original text that may not be fully and accurately translated due to lack of clear and specific context. You can further adjust and optimize according to the actual situation.A support device for a self-unloading semi-trailer includes a semi-trailer trolley; an unloading mechanism mounted on the semi-trailer trolley, the unloading mechanism including a storage compartment mounted on the semi-trailer trolley, a rotating unloading assembly mounted on one side wall of the storage compartment, a positioning support assembly mounted on the rotating unloading assembly, a first rotating assembly within the storage compartment, and a second rotating assembly mounted on the rotating unloading assembly. The first rotating assembly is used to move goods toward the rotating unloading assembly, and the second rotating assembly drives the goods in the same direction as the first rotating assembly. The device also includes a power assembly within the storage compartment for driving the first and second rotating assemblies; and a fixing mechanism mounted on the semi-trailer trolley.
[0007] By adopting the above technical solution, the semi-trailer provides a mobile base for the entire support device, facilitating the transportation of goods to designated locations. The storage compartment in the unloading mechanism stores goods, and the rotating unloading assembly controls the opening and closing of the storage compartment, facilitating unloading. The positioning support assembly supports the rotating unloading assembly and positions the goods, ensuring the unloading process and the stability of the transportation process. The first and second rotating assemblies cooperate, driving the goods in the same direction, efficiently pushing the goods from the storage compartment towards the rotating unloading assembly, achieving automatic unloading. The power assembly uniformly drives the first and second rotating assemblies, reducing the number of power devices, lowering costs, and improving the coordination of the movements of each component. The fixing mechanism, located on the semi-trailer, secures the device during unloading, preventing displacement or swaying due to a shift in the center of gravity, ensuring operational safety, and overall improving the unloading efficiency and operational stability of the self-dumping semi-trailer.
[0008] Preferably, the semi-trailer includes a support plate, a connecting part is provided below the support plate, and a trailer wheel is provided on the connecting part.
[0009] By adopting the above technical solution, the support plate serves as the load-bearing foundation of the entire semi-trailer and can support other components; the connecting part is used to connect the support plate and the trailer wheels; the trailer wheels enable the semi-trailer to move, facilitating the transportation of goods.
[0010] Preferably, the rotary unloading assembly includes a rotary connecting seat disposed on the support plate, a rotary shaft disposed on the rotary connecting seat, the rotary shaft passing through the rotary connecting seat, a flip plate connected to the rotary shaft, a rotary threaded hole disposed on one side of the flip plate for bolting connection with the storage bin, and a locking assembly disposed on the other side of the flip plate.
[0011] By adopting the above technical solution, the rotary unloading assembly is mounted on the support plate. The rotary connecting seat and rotary shaft cooperate to allow the tilting plate to rotate around the shaft, achieving a tilting function and facilitating the unloading of materials from the storage bin. A rotary threaded hole on one side of the tilting plate can be bolted to the storage bin. This connection method ensures the stability between the tilting plate and the storage bin, preventing the tilting plate from wobbling during normal use and improving structural stability. A locking assembly on the other side of the tilting plate further enhances the reliability of the connection, preventing the tilting plate from loosening due to vibration or other factors during vehicle movement or other operations. When unloading is required, the operator can easily open or close the rotary unloading assembly, using the tilting plate to smoothly unload the goods. The entire rotary unloading assembly is rationally designed, not only facilitating the unloading operation but also ensuring stable operation of the equipment under different working conditions, improving the working efficiency and safety of the self-unloading semi-trailer.
[0012] Preferably, the locking assembly includes a first locking block disposed on the flip plate and a second locking block disposed on the outer wall of the storage compartment, and further includes a locking rod passing through the first locking block and the second locking block, the locking rod being slidably connected to the first locking block and the second locking block.
[0013] By adopting the above technical solution, the first locking block, the second locking block and the locking rod can be used to securely connect the tilting plate and the storage bin, preventing the tilting plate from accidentally loosening or separating during use, and improving the stability and reliability of the unloading mechanism.
[0014] Preferably, the positioning support assembly includes a support sleeve horizontally disposed on the flip plate. A first support plate is disposed inside the support sleeve on the side near the storage compartment, and a second support plate is disposed inside the support sleeve on the side away from the storage compartment. The first support plate and the second support plate are slidably connected inside the support sleeve. An adjusting spring is disposed between the first support plate and the second support plate. A support telescopic rod is disposed on the side of the first support plate facing the storage compartment. A support pressing plate is disposed on the side of the support telescopic rod away from the support sleeve. A second support rod is disposed on the side of the second support plate away from the storage compartment.
[0015] By adopting the above technical solution, on the one hand, during transportation, the positioning support assembly can position the goods in the storage compartment according to their size. When the goods are placed in the storage compartment, the support telescopic rod, under the elastic action of the adjusting spring, pushes the support pressing plate against the side of the goods. Since the first and second support plates can slide within the support sleeve, the support pressing plate can adapt to the position of goods of different sizes, thereby stably positioning the goods and preventing them from shaking or colliding and being damaged during transportation. On the other hand, after the rotating unloading assembly rotates, the positioning support assembly, after adjustment, can provide support for the rotating unloading assembly. When the rotating unloading assembly rotates to the designated position for unloading, it will extend and retract according to the rotation angle and position. At the same time, the adjusting spring will also change its compression degree accordingly, so that the support pressing plate can fit in the appropriate position. Together with the second support rod, it forms a stable support structure for the rotating unloading assembly, ensuring the stability and safety of the rotating unloading assembly during the unloading process.
[0016] Preferably, the first rotating assembly includes a plurality of first springs disposed on the support plate, a first rotating support frame disposed on the first springs, a plurality of first rotating shafts rotatably connected to the first rotating support frame, a first rotating roller disposed on the first rotating shaft, and a first bearing plate disposed above the support plate, the first bearing plate being provided with a plurality of first mounting holes, the first mounting holes corresponding one-to-one with the first rotating rollers.
[0017] By adopting the above technical solution, the storage compartment on the semi-trailer can store goods. The first spring and the first rotating support frame can provide a certain buffer and support, so that the first rotating shaft and the first rotating roller can rotate stably. The first rotating roller can rotate under the drive of the power component, driving the goods in the storage compartment to move towards the rotating unloading component. The first bearing plate and the first mounting hole on it can limit and guide the first rotating roller, ensuring the direction and stability of the goods conveying.
[0018] Preferably, the second rotating assembly includes a second rotating support frame disposed on the flip plate, the second rotating support frame being provided with a plurality of second rotating rollers, and a second bearing plate disposed on the side of the flip plate pointing towards the storage compartment, the second bearing plate being provided with a plurality of second mounting holes, the second mounting holes corresponding one-to-one with the second rotating rollers.
[0019] By adopting the above technical solution, the second rotating roller on the second rotating support frame can be used to assist the movement of goods, and the second bearing plate and the corresponding second mounting hole can position and support the second rotating roller, ensuring that the goods are stably conveyed to one side of the rotating feeding assembly.
[0020] Preferably, the power assembly includes a rotary motor mounted on the second rotary support frame, a power shaft at the drive end of the rotary motor, the power shaft being coaxial with the rotary shaft, a first drive sprocket and a second drive sprocket mounted on the power shaft, a first transmission chain mounted on the first drive sprocket and a second transmission chain mounted on the second drive sprocket, and a plurality of driven sprockets mounted on the first rotary shaft and the second rotary shaft, the first transmission chain being connected to the driven sprockets on the first rotary shaft and the second rotary chain being connected to the driven sprockets on the second rotary shaft.
[0021] By adopting the above technical solution, the rotating motor drives the power shaft to rotate. Since the power shaft and the rotating shaft are coaxially arranged, the relevant components can work together. The first and second drive sprockets on the power shaft are connected to the driven sprockets on the first and second rotating shafts respectively through the first and second transmission chains. They can simultaneously drive the first and second rotating components to move, so that the goods can move smoothly towards the rotating unloading component and the two drive the goods in the same direction, ensuring the orderly transportation of goods.
[0022] Preferably, the fixing mechanism includes a sliding track disposed on the outer wall of the storage compartment. The sliding track is vertically disposed, and a sliding slider is slidably connected inside the sliding track. A positioning motor is disposed on the sliding slider, and a threaded shaft is disposed at the transmission end of the positioning motor. The threaded shaft is vertically disposed, passes through the support plate, and is helically connected to the support plate. A helical blade is disposed on the side of the threaded shaft pointing towards the ground.
[0023] By adopting the above technical solution, a connecting part and trolley wheels are set below the support plate of the semi-trailer for easy movement. A vertical sliding rail and a sliding slider are set on the outer wall of the storage compartment, which can drive the positioning motor to move up and down. The vertical threaded shaft at the transmission end of the positioning motor is connected to the support plate by a spiral drive, and a spiral blade is set on the side of the threaded shaft pointing to the ground. This allows the threaded shaft to penetrate deep into the ground, so as to achieve a stable fixation of the support device for the self-unloading semi-trailer.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Driven by the power component, the first rotating component and the second rotating component drive the goods to move towards the side of the rotating unloading component. The two drive in the same direction, which can better control the unloading direction and speed of the goods, avoid uneven accumulation of goods of different shapes, weights and properties, and reduce the workload of subsequent sorting and handling. 2. The rotating shaft of the rotating unloading component can drive the tilting plate to rotate, making it easy to adjust the unloading angle. The positioning support component set on it, through the support telescopic rod, support pressing plate and other structures, helps to ensure the overall structural stability and prevents the goods from falling due to shaking during unloading. 3. The sliding block of the fixing mechanism can slide along the sliding track. The positioning motor drives the threaded shaft to rotate and has a screw drive with the support plate, so that the threaded shaft descends and the spiral blades insert into the ground, which plays a role in fixing the device. It works in conjunction with the unloading mechanism to effectively reduce the possibility of accidents caused by the semi-trailer's own unstable center of gravity during the unloading process.

The unloading mechanism 2 is installed on the semi-trailer 1, and the fixing mechanism 3 is also installed on the semi-trailer 1. This arrangement can ensure the stability of the semi-trailer during the unloading process, and the unloading mechanism 2 can more accurately control the unloading direction and speed of the cargo.
[0029] In practice, the goods are placed on the semi-trailer 1, and then the semi-trailer is transported to the unloading location. The fixing mechanism 3 fixes the semi-trailer 1 to the ground, and then the unloading mechanism 2 unloads the goods from the semi-trailer 1.
[0030] Reference Figure 1 Specifically, the semi-trailer 1 includes a support plate 101 and trailer wheels 103. A connecting part 102 is provided below the support plate 101, and the trailer wheels 103 are mounted on the connecting part 102. The support plate 101 is generally made of metal, rectangular in shape, and has a certain strength and load-bearing capacity; its function is to support the unloading mechanism 2 and the weight of the cargo. The connecting part 102 can be a metal frame welded below the support plate 101, serving to connect the support plate 101 and the trailer wheels 103. The trailer wheels are mounted on the connecting part 102 via bearings, allowing the semi-trailer 1 to move flexibly.
[0031] In actual operation: the goods are placed on the support plate 101, and the semi-trailer 1 is moved by the external power mechanism.
[0032] Reference Figures 2-4 The unloading mechanism 2 includes a storage bin 201, a rotary unloading assembly 202, a positioning support assembly 203, a first rotating assembly 204, a second rotating assembly 205, and a power assembly 206. The storage bin 201 is mounted on the semi-trailer 1, is generally welded from steel plates, and is rectangular in shape, used for storing goods.
[0033] In actual operation, the rotating unloading assembly 202 is rotated to make it contact the ground. Then, the first rotating assembly, the second rotating assembly 205 and the power unit work to transport the goods to the ground.
[0034] Reference Figures 2-4The rotary unloading assembly 202 includes a rotary connecting seat 2021, a rotary shaft 2022, a tilting plate 2023, and a locking assembly 207.

One side of the tilting plate 2023 has a rotary threaded hole for bolt connection to the storage compartment 201, facilitating installation and disassembly. The other side of the tilting plate 2023 has the locking assembly 207. The locking assembly 207 includes a first locking block 2071, a second locking block 2072, and a locking rod 2073. The first locking block 2071 is disposed on the flip plate 2023, and the second locking block 2072 is disposed on the outer wall of the storage compartment 201. Both can be cast metal blocks. The locking rod 2073 passes through the first locking block 2071 and the second locking block 2072 and is slidably connected to them. The locking rod 2073 is L-shaped.
[0035] In specific operation: During transportation, the flip plate 2023 is connected to the storage compartment 201. To fix the flip plate 2023, the locking rod 2073 is inserted into the holes of the first locking block 2071 and the second locking block 2072 to fix it. When it is necessary to open the flip plate 2023, the locking rod 2073 can be pulled out. The locking rod 2073 is L-shaped to prevent it from falling off. During unloading, the flip plate rotates around the rotating shaft 2022 and one end contacts the ground.

The first support plate 2032 is located on the side of the support sleeve 2031 closest to the storage compartment 201, and the second support plate 2033 is located on the side away from the storage compartment 201. The first support plate 2032 and the second support plate 2033 are slidably connected within the support sleeve 2031. An adjusting spring 2034 is located between the first support plate 2032 and the second support plate 2033, and the function of the adjusting spring 2034 is to provide elastic support force. A support telescopic rod 2035 is provided on the side of the first support plate 2032 facing the storage compartment 201. The support telescopic rod 2035 is also provided with several locking threaded holes. The support telescopic rod 2035 is locked by bolts and its length can be adjusted as needed. A support pressing plate 2036 is provided on the side of the support telescopic rod 2035 away from the support sleeve 2031. The side of the support pressing plate 2036 away from the support sleeve 2031 is a rough surface. A second support rod 2037 is provided on the side of the second support plate 2033 away from the storage compartment 201. The second support rod 2037 is also provided with several locking threaded holes.
[0037] In actual operation, there are two states. In the transportation state, the flip plate 2023 is connected to the storage compartment 201, the second support plate 2033 is fixed to the support sleeve 2031 by bolts, and the support pressing plate 2036 presses on the goods. The support telescopic rod 2035 is used to make an initial adjustment to the distance of the support pressing plate 2036, and the adjustment spring 2034 is used to make a fine adjustment to the distance of the support pressing plate 2036 to adapt to different cargo sizes, thereby fixing the goods in the storage compartment 201 and preventing shaking.
[0038] During the unloading process, the tilting plate 2023 rotates and contacts the ground. The telescopic rod is retracted, and the supporting telescopic rod 2035 is fixed to the supporting sleeve 2031 by bolts. At this time, the supporting pressing plate 2036 is attached to the tilting plate 2023, and the second supporting rod 2037 is pressed on the ground, providing support for the tilting plate 2023. At the same time, the rough surface of the supporting pressing plate 2036 can slow down the falling goods and reduce the possibility of the goods tipping over rapidly during the unloading process.

The second bearing plate 2054 is located on the side of the tilting plate 2023 facing the storage compartment 201 and has several second mounting holes 2055. Each second mounting hole 2055 corresponds to one of the second rotating rollers 2053, facilitating the rotation of the second rotating rollers 2053. Each set of second rotating rollers 2053 protrudes from the second mounting holes 2055 and can contact the surface of the goods.
[0042] In actual operation, the power unit 206 drives the second rotating roller 2053 to rotate, transporting the goods to the ground.

The threaded shaft 304 is vertically mounted, passes through the support plate 101, and is helically connected to the support plate 101. A helical blade 305 is mounted on the side of the threaded shaft 304 pointing towards the ground.
[0046] In actual operation: when the positioning motor 303 starts, the threaded shaft 304 rotates, and the threaded shaft 304 descends through the screw drive. At the same time, the spiral blade 305 rotates and inserts into the ground, which plays the role of fixing the semi-trailer 1 and preventing the semi-trailer from overturning or becoming unstable due to the shift of the center of gravity.
[0047] The implementation principle of a support device for a self-unloading semi-trailer according to an embodiment of this application is as follows: In use, the semi-trailer trolley 1 is first fixed in a suitable position by the fixing mechanism 3. The positioning motor 303 is started, causing the threaded shaft 304 to descend and the spiral blades 305 to insert into the ground. Then, the locking component 207 of the rotating unloading assembly 202 is opened, and the tilting plate 2023 is lowered. The rotation motor 2061 of the power assembly 206 is started, driving the rotating rollers of the first rotating assembly 204 and the second rotating assembly 205 to rotate through the transmission system. The first rotating assembly 204 moves the goods towards the rotating unloading assembly 202, and the second rotating assembly 205 continues to drive the goods to move, thereby unloading the goods from the storage compartment 201. The positioning support component 203 can support and position the tilting plate 2023, ensuring the stability of the unloading process. This support device can adapt to goods of different shapes, weights, and properties, precisely control the unloading direction and speed of the goods, avoid uneven stacking and spillage of goods, reduce the workload of subsequent sorting and handling, reduce the risk of damage to goods, and improve transportation efficiency. It is a significant improvement over existing technologies.
