Description

Technical Field

[0001] This invention relates to the field of transport vehicle technology, and in particular to a new energy container transport semi-trailer. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the high energy consumption and pollution of traditional fuel-powered transport vehicles have become increasingly prominent, prompting the transportation industry to transform towards new energy sources. Against this backdrop, new energy container semi-trailers have emerged. These semi-trailers are transport vehicles powered by new energy sources, with their cargo compartments using a container structure to form a container-like semi-trailer. This design not only inherits many advantages of container transport, such as standardization, convenient loading and unloading, and high transport efficiency, but also achieves the goal of low-carbon and environmentally friendly transport by leveraging new energy power. New energy container semi-trailers have a wide range of applications, including long-distance road transport, port short-haul transport, and urban distribution. They are also suitable for areas with high environmental protection requirements, such as industrial parks and green logistics parks, effectively reducing carbon emissions during transportation and minimizing environmental pollution. At the same time, their standardized container structure facilitates seamless integration with other modes of transport such as rail and sea, enabling multimodal transport and further improving the overall efficiency and flexibility of logistics transportation.

[0003] During the assembly of containers and semi-trailers, spreaders are usually used to lift the containers to the cargo area of ​​the semi-trailers. At this time, the corner fittings at the bottom of the container need to be aligned with the cylindrical locks around the cargo area of ​​the semi-trailers. As the container falls, the lock heads will be embedded in the recesses of the corner fittings, thereby securing the container.

[0004] In existing container and semi-trailer installation methods, only the bottom four sides of the container are fixed, without effectively connecting the container to the semi-trailer frame. This connection method has obvious defects during vehicle operation. When the semi-trailer travels on bumpy roads or makes sharp turns, the container will generate lateral forces and lateral displacement due to inertia, causing relative sliding between the bottom of the container and the semi-trailer frame. This sliding phenomenon mainly occurs because the fixing points around the bottom of the container cannot provide sufficient lateral restraint force to effectively resist the displacement of the container under lateral forces. As the bottom of the container slides, its weight will be concentrated and transferred to the semi-trailer frame on one side, forming an uneven lateral load. Under this load for a long time, the semi-trailer frame is prone to deformation. In addition, the sliding of the bottom of the container will also cause friction between it and the fixed cylindrical lock, further weakening the fixing effect and service life of the lock.

[0005] To address the aforementioned issues, this application proposes a new energy container transport semi-trailer. Summary of the Invention

[0006] This invention proposes a new energy container transport semi-trailer, which solves the problem in the existing technology where the container and semi-trailer are only fixed around the bottom and not effectively connected to the main beam. During operation, the container generates lateral force and lateral displacement due to inertia, causing the bottom to slide relative to the frame. This sliding causes the weight to be concentrated on one side of the main beam, forming an uneven load, which can easily lead to deformation of the main beam. Furthermore, the sliding friction weakens the fixing effect and lifespan of the locking device.

[0007] The present invention proposes a new energy container transport semi-trailer, comprising a semi-trailer body and a container body hoisted on top of it;

[0008] The semi-trailer body is equipped with two main beams, and multiple crossbeams are installed between the two main beams. Loading blocks are installed inside the crossbeams, and two slots are symmetrically opened inside the loading blocks. Multiple sets of inclined blocks are installed at the bottom of the box body, and each set of inclined blocks corresponds to the two slots inside the loading block.

[0009] The crossbeam is equipped with two locking and pushing components, and each of the two main beams is equipped with a limiting component that cooperates with the locking and pushing components. The bottom sides of the box are provided with grooves, and the two grooves are respectively adapted to the two limiting components.

[0010] Both main beams are equipped with protective components that cooperate with the locking and pushing components on their outer sides;

[0011] When the enclosure is hoisted, it moves down along the protective components. The inclined block at the bottom is inserted into the slot by the locking and pushing components. The locking and pushing components are pushed outward by force, pushing the limiting components to move upward and insert into the groove at the bottom of the enclosure. This pushes the two protective components to move upward, providing protection on both sides of the enclosure.

[0012] As a further optimization of the present invention, the locking and pushing assembly includes a first locking block, a second locking block, a slider, and an elastic pusher. A first locking block and a second locking block located within a crossbeam are provided above each of the two slots. Sliding openings are provided on both sides of the crossbeam. Slider blocks are fixed to both sides of the first locking block and the second locking block. The two sliders slide in cooperation with the two sliding openings respectively. The two first locking blocks cooperate with two protective components respectively. An elastic pusher is installed on the side of each of the two first locking blocks that is far apart from each other. The two elastic pushers cooperate with two limiting components respectively. An insertion area for a wedge to pass through is formed between the first locking block and the second locking block. A first inclined surface is formed on the adjacent side of the first locking block and the second locking block. Each set of wedges consists of two wedges arranged symmetrically. The two wedges tilt from both sides of the housing towards the center and cooperate with the first inclined surfaces on the first locking block and the second locking block. A loading hole is provided on the adjacent side of the first locking block and the loading hole is equipped with a pressure sensor.

[0013] As a further optimization of the present invention, the elastic pusher includes a fixed rod, a push block and a first spring. Fixed rods are installed at the ends of the two first locking blocks that are far apart from each other. The two fixed rods slide through the two ends of the two crossbeams respectively. Push blocks are installed at the ends of the two fixed rods that are far apart from each other. The two push blocks slide through the two main beams respectively. The two push blocks cooperate with two limiting components. The first spring is sleeved on the fixed rod, and the two ends of the first spring are respectively connected to the inner walls of the first locking blocks and the crossbeams.

[0014] As a further optimization of the present invention, the limiting component includes a limiting block and an elastic force-bearing component. The top of each of the two main beams is provided with a placement opening, and a limiting block is provided in each of the two placement openings. The two limiting blocks are respectively adapted to two grooves. A magnetic block is installed in the groove. An electromagnet for magnetic connection with the magnetic block is installed on the limiting block. An elastic force-bearing component is connected to the bottom of each of the two limiting blocks, and the two elastic force-bearing components cooperate with two push blocks respectively.

[0015] As a further optimization of the present invention, the elastic force-bearing component includes a force-bearing rod, a force-bearing block and a second spring. The top of the main beam is slidably connected to the force-bearing rod, which extends into the placement opening and is connected to the limiting block. The bottom of the force-bearing rod is equipped with a force-bearing block that cooperates with the push block. A second inclined surface is formed on the push block, and a third inclined surface that cooperates with the second inclined surface is formed at the bottom of the force-bearing block.

[0016] As a further optimization of the present invention, the protective component includes a protective member and a pneumatic support member. The outer sides of both main beams are provided with protective members, and the bottom of the protective member is equipped with a pneumatic support member that is fixed to the main beam, and the pneumatic support member cooperates with the first locking block.

[0017] As a further optimization of the present invention, the protective component includes strips and protective rods. Strips are provided on the outer sides of both main beams. The strips are connected to pneumatic support components. Multiple protective rods are installed on the strips at intervals. Side ear frames are installed on both sides of the box body. Openings adapted to the strips are opened in both side ear frames. Rope holes are opened at the top of the protective rods. Rope frames are installed on the top of the box body.

[0018] As a further optimization of the present invention, the pneumatic support component includes a fixed cylinder, an air cylinder, and a guide tube. Fixed cylinders are installed on the outer sides of both main beams, and elastic support parts are installed inside both fixed cylinders. The top end of the elastic support part passes through the top of the fixed cylinder. Two strips are respectively installed on the two elastic support parts. The bottom of the fixed cylinder is connected to an air cylinder that is directly opposite the first locking block through a guide tube, and the air cylinder is fixedly connected to the main beam. A first piston is slidably arranged inside the air cylinder, and a shaft connected to the first locking block is installed on the outer end of the first piston.

[0019] As a further optimization of the present invention, the elastic top support includes a top support rod, a second piston, and a third spring. The top support rod is slidably inserted into the fixed cylinder, and the bottom end of the top support rod is equipped with the second piston located inside the fixed cylinder. The third spring is sleeved on the top support rod, and the two ends of the third spring are respectively connected to the second piston and the top wall inside the fixed cylinder. The top of the fixed cylinder is provided with an air hole for the second piston to discharge gas when it moves upward. The strip is installed at the top of the two top support rods.

[0020] As a further optimization of the present invention, cylindrical locks are installed at both ends of the two main beams, and recessed holes are opened around the bottom of the box body, and the recessed holes are adapted to the cylindrical locks.

[0021] The above-described technical solution of the present invention has the following beneficial technical effects:

[0022] 1. When the container is hoisted and lowered, the inclined blocks on both sides of the container can move down along the protective components on the two main beams. The protective components act as guides. When the container moves down, the corresponding inclined blocks at the bottom will pass through the insertion area formed between the first and second locking blocks on the locking and pushing components. The first and second locking blocks move laterally outward under the action of the inclined blocks moving down. After the inclined blocks are inserted into the slots of the loading blocks located in the crossbeam, the first and second locking blocks abut against the two sides of the inclined blocks respectively, thereby fixing the middle part of the bottom surface of the container. The above design can effectively limit the lateral displacement of the middle part of the bottom surface of the container, thereby providing stronger lateral restraint force for the container and preventing it from lateral displacement due to inertia during vehicle movement. In addition, this structural design makes the connection between the middle part of the bottom surface of the container and the semi-trailer body tighter and more stable, enhancing the overall connection strength between the container and the semi-trailer body and improving the fixing stability.

[0023] 2. In this invention, when the two first locking blocks located inside the crossbeam move outward, the limiting components can be pushed upward by the elastic pusher connected to the first locking blocks, so that the limiting components on the two main beams are respectively inserted into the two grooves on both sides of the bottom of the box. Then, the electromagnet on the limiting component is energized, so that it is magnetically connected to the magnetic block in the groove, thus completing the fixation of the bottom sides of the box. The above design allows the weight of the box to be more evenly distributed on the main beam of the semi-trailer, avoiding the situation where the weight is concentrated on one side of the main beam of the semi-trailer due to the sliding of the bottom of the box, thereby reducing the risk of deformation of the main beam of the semi-trailer due to uneven load. In addition, this double fixing method further enhances the connection strength between the bottom of the box and the semi-trailer, making the box more stable during vehicle operation and effectively resisting various external forces. Moreover, the energization and de-energization of the electromagnet can flexibly control the fixing state between the limiting components and the box, making it easy to quickly release the fixation or readjust the fixing position when needed, improving the flexibility and convenience of operation.

[0024] 3. When the two first locking blocks of the present invention move outward, they can push the two protective components upward respectively, extending the length of the protective distance on both sides of the box. Then, one end of several pull ropes can be fixed to the top of the box, and the other end can be connected to the protective components on the outside of the two main beams respectively, so that the pull ropes can pull and fix the protective components, keep the position of the first locking blocks, and enable the locking and pushing components to stably limit the inclined blocks at the bottom of the box, avoiding the displacement of the first and second locking blocks due to external forces, which would affect the fixing effect of the box. In addition, the cooperation between the pull ropes and the protective components can form a protective barrier on the outside of the box to protect and buffer when the side of the box is hit, reduce the damage to the box caused by the impact, and improve the safety of the box during transportation.

[0025] 4. This invention equips the bottom of the container with multiple sets of inclined blocks, which can maintain a certain distance between the container and the ground when it is hoisted and placed on the ground, avoiding direct contact between the container and the ground. This reduces the erosion and pollution of the container bottom caused by factors such as ground moisture and dirt, extends the service life of the container, and also prevents sharp objects on the ground from damaging the bottom of the container. It also reduces the risk of damage to the bottom of the container due to uneven ground or the presence of debris, ensuring the integrity and structural strength of the container bottom and guaranteeing its normal use in subsequent transportation.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0044] like Figures 1-16As shown, the present invention proposes a new energy container transport semi-trailer, which includes a semi-trailer body 1 and a container body 2 hoisted on top of it;

[0045] Two main beams 101 are installed on the semi-trailer body 1. Multiple crossbeams 102 are installed between the two main beams 101. Loading blocks 103 are installed inside the crossbeams 102. Two slots 104 are symmetrically opened inside the loading blocks 103. Multiple sets of inclined blocks 21 are installed at the bottom of the box body 2. Each set of inclined blocks 21 corresponds to the two slots 104 inside the loading blocks 103.

[0046] Two locking and pushing components 3 are provided inside the crossbeam 102. Limiting components 4 that cooperate with the locking and pushing components 3 are installed on both main beams 101. Grooves 22 are provided on both sides of the bottom of the box body 2. The two grooves 22 are respectively adapted to the two limiting components 4.

[0047] Both main beams 101 are equipped with protective components 5 that cooperate with the locking and pushing components 3 on their outer sides;

[0048] When the housing 2 is hoisted, it moves down along the protective component 5. The inclined block 21 at its bottom is inserted into the slot 104 through the locking and pushing component 3. The locking and pushing component 3 is forced to move outward, pushing the limiting component 4 to move up and insert into the groove 22 at the bottom of the housing 2, and pushing the two protective components 5 to move up, providing protection on both sides of the housing 2.

[0049] When the container 2 is hoisted, it can be moved down along the protective component 5. The bottom inclined block 21 is inserted into the slot 104 of the loading block 103 by the locking and pushing component 3. During this process, the inclined block 21 forces the locking and pushing component 3 to move outward, thereby pushing the two limiting components 4 to move upward and insert into the two grooves 22 at the bottom of the container 2 respectively. At the same time, it pushes the two protective components 5 to move upward, forming protection on both sides of the container 2. The above realizes the connection between the bottom sides of the container 2 and the two main beams 101 on the semi-trailer body 1, and also realizes the connection of the middle part of the bottom surface of the container 2, ensuring the stability of the container 2 during transportation.

[0050] In this embodiment, the locking and pushing assembly 3 includes a first locking block 31, a second locking block 32, a slider 33, and an elastic pusher 34. A first locking block 31 and a second locking block 32 located within a crossbeam 102 are respectively disposed above the two slots 104. Sliding openings 105 are provided on both sides of the crossbeam 102. Sliding blocks 33 are fixed to both sides of the first locking block 31 and the second locking block 32. The two sliders 33 slide in cooperation with the two sliding openings 105 respectively. The two first locking blocks 31 cooperate with the two protective assemblies 5 respectively. An elastic pusher 34 is installed on the side of the two first locking blocks 31 that is furthest away from each other. The pusher 34, two elastic pushers 34 respectively cooperate with two limiting components 4, and an insertion area for the inclined block 21 to pass through is formed between the first locking block 31 and the second locking block 32. The first locking block 31 and the second locking block 32 are each formed on the adjacent side. There are two inclined blocks 21 in each group and they are arranged symmetrically. The two inclined blocks 21 are inclined from both sides of the box 2 toward the middle and cooperate with the first inclined surfaces on the first locking block 31 and the second locking block 32. The first locking block 31 and the second locking block 32 are each provided with a loading hole on the adjacent side. A pressure sensor 35 is installed in the loading hole.

[0051] When the inclined block 21 at the bottom of the housing 2 moves down, it passes through the insertion area formed between the first locking block 31 and the second locking block 32. Since the two inclined blocks 21 of each set of inclined blocks 21 are inclined from both sides of the housing 2 towards the middle, their inclined surfaces will contact the first inclined surfaces of the adjacent sides of the first locking block 31 and the second locking block 32 and generate a force. Under this force, the first locking block 31 and the second locking block 32 will slide outward along the sliding opening 105 on the crossbeam 102 through the sliders 33 on both sides. At the same time, the two first locking blocks 31 move away from each other. The elastic pusher 34 on one side pushes the limiting component 4 upward and inserts it into the groove 22 at the bottom of the box 2. When the first locking block 31 moves outward, it pushes the protective component 5 upward, extending the protective length on both sides of the box 2. The pressure sensor 35 in the loading hole on the first locking block 31 and the second locking block 32 can monitor the lateral force on the inclined block 21 during transportation, and can also monitor the contact status between the inclined block 21 and the first locking block 31 and the second locking block 32 in real time, so as to determine whether the box 2 is installed in place.

[0052] In this embodiment, the elastic pusher 34 includes a fixed rod 341, a push block 342, and a first spring 343. The two first locking blocks 31 are each equipped with a fixed rod 341 at their opposite ends. The two fixed rods 341 slide through the two ends of the two crossbeams 102 respectively. The two push blocks 342 slide through the two main beams 101 respectively. The two push blocks 342 cooperate with the two limiting components 4. The fixed rod 341 is fitted with a first spring 343, and the two ends of the first spring 343 are respectively connected to the inner walls of the first locking blocks 31 and the crossbeams 102.

[0053] When the first locking block 31 moves outward under the action of the inclined block 21, it will drive the fixed rod 341 connected to it to move outward synchronously. Since the fixed rod 341 slides through both ends of the crossbeam 102, its movement will push the push block 342 located at the end to slide along the main beam 101. During this process, the first spring 343 sleeved on the fixed rod 341 will be compressed due to the relative movement between the first locking block 31 and the inner wall of the crossbeam 102. The push block 342 will contact the limiting component 4 during the sliding process, thereby transmitting the lateral movement force of the first locking block 31 to the limiting component 4, causing it to move upward and insert into the groove 22 at the bottom of the box 2. The above design realizes the transmission of force from the locking push component 3 to the limiting component 4, providing power for the action of the limiting component 4. The elastic effect of the first spring 343 can not only assist the first locking block 31 to reset when the box 2 is disassembled, but also buffer the lateral impact force on the first locking block 31 during transportation, enhancing the stability and durability of the structure.

[0054] In this embodiment, the limiting component 4 includes a limiting block 41 and an elastic force-bearing component 42. The top of each of the two main beams 101 is provided with a placement opening, and each of the two placement openings is provided with a limiting block 41. The two limiting blocks 41 are respectively adapted to two grooves 22. A magnetic block 221 is installed in the groove 22. An electromagnet 411 for magnetic connection with the magnetic block 221 is installed on the limiting block 41. The bottom of each of the two limiting blocks 41 is connected to an elastic force-bearing component 42, and the two elastic force-bearing components 42 are respectively engaged with two push blocks 342.

[0055] When the push block 342 of the elastic pusher 34 moves outward, it will contact the elastic force-receiving member 42 of the limiting component 4 and apply force. Under this force, the elastic force-receiving member 42 pushes the limiting block 41 upward until the limiting block 41 is inserted into the corresponding groove 22 at the bottom of the box 2. At this time, the magnetic block 221 installed in the groove 22 and the electromagnet 411 installed on the limiting block 41 approach each other. The electromagnet 411 generates magnetism by being energized, realizing a magnetic connection with the magnetic block 221, thereby stably fixing the limiting block 41 in the groove 22. The above design drives the limiting block 41 to cooperate with the groove 22 through the force transmitted by the push block 342. Combined with the magnetic connection between the magnetic block 221 and the electromagnet 411, a double fixation is formed, which enhances the connection strength between the bottom sides of the box 2 and the main beam 101, effectively restricts the lateral and longitudinal displacement of the box 2. The on and off of the electromagnet 411 can flexibly control the fixed state, which facilitates the loading and unloading operation of the box 2 and improves the ease of use.

[0056] In this embodiment, the elastic force-bearing member 42 includes a force-bearing rod 421, a force-bearing block 422, and a second spring 423. The top of the main beam 101 is slidably connected to the force-bearing rod 421, which extends into the placement opening and is connected to the limiting block 41. The bottom of the force-bearing rod 421 is equipped with a force-bearing block 422 that cooperates with the push block 342. A second inclined surface is formed on the push block 342, and a third inclined surface that cooperates with the second inclined surface is formed at the bottom of the force-bearing block 422. When the push block 342 moves outward under the action of the elastic push member 34, the second inclined surface on the push block 342 will come into contact with the third inclined surface at the bottom of the force-bearing block 422 in the elastic force-bearing member 42. As the push block 342 continues to move, the interaction force between the two inclined surfaces converts the lateral movement force of the push block 342 into a force. The upward vertical force of block 422 causes the force-bearing block 422 to move the force-bearing rod 421 upward. The upward movement of the force-bearing rod 421 will simultaneously drive the limiting block 41 to move upward along the placement opening. During this process, the second spring 423 is compressed and stores elastic potential energy. The above design converts the lateral driving force into the vertical driving force through the force conversion effect of the inclined plane, ensuring that the limiting block 41 can move upward smoothly and insert into the groove 22 at the bottom of the box 2, thus ensuring the reliable realization of the fixing function of the limiting component 4. The setting of the second spring 423 can not only assist the force-bearing block 422, the force-bearing rod 421 and the limiting block 41 to reset when the push block 342 is reset, but also buffer the impact of external vibration on the limiting structure during transportation, thereby enhancing the stability and service life of the overall structure.

[0057] In this embodiment, the protective component 5 includes a protective member 51 and a pneumatic support member 52. The outer sides of the two main beams 101 are provided with protective members 51. The bottom of the protective member 51 is equipped with a pneumatic support member 52 that is fixed to the main beam 101, and the pneumatic support member 52 cooperates with the first locking block 31. When the first locking block 31 in the locking push component 3 moves outward, it will generate a thrust on the pneumatic support member 52 in the protective component 5. Under the action of this thrust, the pneumatic support member 52 starts and generates an upward thrust, pushing the protective member 51 to move upward along the outer side of the main beam 101, thereby extending the protective length of the protective member 51 on both sides of the box 2 and enhancing the protective coverage of the sides of the box 2.

[0058] In this embodiment, the protective component 51 includes strips 511 and protective rods 512. Strips 511 are provided on the outer sides of both main beams 101. The strips 511 are connected to the pneumatic support component 52. Multiple spaced protective rods 512 are installed on the strips 511. Side ear frames 24 are installed on both sides of the housing 2. Each side ear frame 24 has an opening adapted to the strips 511. Rope holes are provided at the top of the protective rods 512. A rope frame 25 is installed on the top of the housing 2. When the pneumatic support component 52 is activated, it pushes the strips 511 in the protective component 51 upwards. The strips 511 drive the multiple protective rods 512 installed on them to move upwards synchronously. At this time, the positions of the side ear frames 24 on both sides of the housing 2 and the strips 511 are aligned. As the strip 511 moves upward, it enters the opening inside the side ear frame 24, thus cooperating with the side of the box 2. At the same time, one end of the pull rope can be passed through the rope hole at the top of the protective rod 512, and the other end can be connected to the rope frame 25 at the top of the box 2. The pull rope is used to pull and fix the protective component 5 and the box 2. The cooperation between the strip 511 and the side ear frame 24 enhances the connection between the protective component 5 and the box 2. After the protective rod 512 moves upward, it expands the side protection range. The pull rope, through the rope hole and the rope frame 25, further reinforces the position of the protective component 5 and restricts the position of the locking and pushing component 3. At the same time, it forms a lateral constraint on the box 2, reduces shaking during transportation, and improves the stability and safety of the overall structure.

[0059] It should be noted that: when the housing 2 is installed, its side ear frames 24 on both sides can be respectively fitted onto the protective rods 512 of the two protective components 5, so that it moves down along the protective rods 512 and the protective rods 512 play a guiding role.

[0060] In this embodiment, the pneumatic support component 52 includes a fixed cylinder 521, an air cylinder 522, and a conduit 523. Fixed cylinders 521 are installed on the outer sides of both main beams 101. Elastic support parts 524 are installed inside both fixed cylinders 521, and the top of the elastic support part 524 passes through the top of the fixed cylinder 521. Two strips 511 are respectively installed on the two elastic support parts 524. The bottom of the fixed cylinder 521 is connected to the air cylinder 522, which is directly opposite to the first locking block 31, through the conduit 523. The air cylinder 522 is fixedly connected to the main beam 101. A first piston 5221 is slidably arranged inside the air cylinder 522. A shaft 5222 connected to the first locking block 31 is installed at the outer end of the first piston 5221.

[0061] When the first locking block 31 in the locking push assembly 3 moves outward, it pushes the shaft 5222 inside the air cylinder 522, causing the shaft 5222 to drive the first piston 5221 to slide inside the air cylinder 522. The sliding of the first piston 5221 forces the gas in the air cylinder 522 into the fixed cylinder 521 through the conduit 523. The air pressure inside the fixed cylinder 521 increases, which in turn pushes the internal elastic support part 524 to move upward. The top of the elastic support part 524 passes through the top of the fixed cylinder 521, causing the protective part 51 connected to it to move upward synchronously. The above design converts the lateral displacement of the first locking block 31 into the vertical displacement of the protective part 51 through pneumatic transmission. The transmission process is smooth and the force transmission efficiency is high, ensuring that the protective part 51 can move upward synchronously with the installation action of the housing 2 in a timely manner, effectively expanding the protection range on both sides of the housing 2.

[0062] In this embodiment, the elastic top support 524 includes a top support rod 5241, a second piston 5242, and a third spring 5243. The top support rod 5241 is slidably inserted into the fixed cylinder 521, and the second piston 5242 located inside the fixed cylinder 521 is installed at the bottom end of the top support rod 5241. The third spring 5243 is sleeved on the top support rod 5241, and the two ends of the third spring 5243 are respectively connected to the second piston 5242 and the top wall inside the fixed cylinder 521. The top of the fixed cylinder 521 is provided with an air hole 5211 for the second piston 5242 to discharge gas when it moves upward. The strip 511 is installed at the top of the two top support rods 5241.

[0063] When gas is introduced into the fixed cylinder 521 through the conduit 523, the increased gas pressure generates an upward thrust on the second piston 5242. Under this thrust, the second piston 5242 moves upward along the inner wall of the fixed cylinder 521, causing the top support rod 5241 connected to it to move upward synchronously. The strip 511 at the top of the top support rod 5241 rises accordingly. At the same time, the third spring 5243 sleeved on the top support rod 5241 is compressed due to the upward movement of the second piston 5242, storing elastic potential energy. During the upward movement of the second piston 5242, the strip 511 located in the fixed cylinder 521... The gas above the second piston 5242 is discharged through the vent 5211 at the top, preventing the gas pressure from affecting the normal movement of the second piston 5242. The above design can realize the smooth rise of the top support rod 5241, thereby driving the protective part 51 to move upward reliably, ensuring the effective expansion of the protection range. The setting of the vent 5211 balances the air pressure in the fixed cylinder 521, ensuring the smooth operation of the elastic top support 524. The third spring 5243 can assist the second piston 5242 and the top support rod 5241 to reset when the air pressure decreases, improving the flexibility and reusability of the structure.

[0064] In this embodiment, cylindrical locks 106 are installed at both ends of the two main beams 101, and recessed holes 23 are opened around the bottom of the box body 2, and the recessed holes 23 are adapted to the cylindrical locks 106. When the box body 2 is hoisted down along the protective component 5 and gradually aligned with the semi-trailer body 1, the cylindrical locks 106 installed at both ends of the main beams 101 will align with the recessed holes 23 opened around the bottom of the box body 2. As the box body 2 continues to move down, the cylindrical locks 106 will gradually insert into the corresponding recessed holes 23, and fix the four corners of the box body 2 by mechanical insertion. This is the prior art and will not be elaborated on. It works in conjunction with other fixing structures to form an all-round constraint on the box body 2.

[0065] The specific working principle of this invention is as follows:

[0066] When the box 2 is hoisted, it first moves down along the protective component 5. The bottom inclined block 21 passes through the insertion area formed by the first locking block 31 and the second locking block 32 in the locking and pushing component 3. The inclined surface of the inclined block 21 cooperates with the first inclined surface of the first locking block 31 and the second locking block 32, pushing the two to slide outward along the sliding opening 105 of the crossbeam 102 through the slider 33. The inclined block 21 is finally inserted into the slot 104 of the loading block 103.

[0067] When the first locking block 31 moves, it drives the fixing rod 341 and the pushing block 342 of the elastic pusher 34 to move. The pushing block 342 cooperates with the third inclined surface of the force-receiving block 422 in the limiting assembly 4 through the second inclined surface, pushing the force-receiving rod 421 and the limiting block 41 to move upward. The limiting block 41 is inserted into the groove 22 at the bottom of the box 2. The magnetic block 221 in the groove 22 is magnetically connected to the electromagnet 411 on the limiting block 41.

[0068] At the same time, the first locking block 31 pushes the shaft 5222 and the first piston 5221 of the pneumatic top support 52 to move inside the air cylinder 522. The gas enters the fixed cylinder 521 through the conduit 523, pushing the second piston 5242 and the top support rod 5241 of the elastic top support part 524 to move upward, which in turn drives the strip 511 and the protective rod 512 of the protective part 51 to move upward. The strip 511 enters the side ear frame 24, and the pull rope passes through the rope hole and the rope frame 25 of the protective rod 512 for fixation.

[0069] In addition, the cylindrical locks 106 at both ends of the main beam 101 are inserted into the recesses 23 at the bottom of the box 2 to fix the four corners; the components work together to fix and protect the box 2 from multiple positions and directions to ensure the stability and safety of the transportation process.

[0070] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
