Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, and in particular to a new energy container transport semi-trailer. Background Art

[0002] With the increasing global attention to environmental protection and sustainable development, the high energy consumption and high pollution problems of traditional fuel transport vehicles have become increasingly prominent, prompting the transportation industry to transform to new energy. Against this background, new energy container transport semi-trailers have emerged. This semi-trailer is a transport vehicle powered by new energy. Its cargo part adopts a container structure to form a container-shaped semi-trailer. This design not only inherits many advantages of container transportation, such as standardization, convenient loading and unloading, and high transportation efficiency, but also achieves low-carbon and environmentally friendly transportation goals with the help of new energy power. The application range of new energy container transport semi-trailers is wide. It can be used in various scenarios such as long-distance road transportation, short-distance port transportation, and urban distribution. It is also suitable for areas with high environmental protection requirements, such as industrial parks and green logistics parks. It can effectively reduce carbon emissions during transportation and reduce pollution to the environment. At the same time, its standardized container structure facilitates seamless connection with other modes of transportation such as railways and sea transportation to achieve multimodal transport, further improving the comprehensive efficiency and flexibility of logistics transportation. During the assembly process of the container and the semi-trailer, a spreader is usually used to lift the container to the cargo area of ​​the semi-trailer. At this time, the corner fittings around the bottom of the container need to be aligned with the cylindrical locks around the cargo area of ​​the semi-trailer. As the container falls, the lock heads will fit into the recessed holes of the corner fittings, thus securing the container. In the existing installation method of containers and semi-trailers, only the four sides of the bottom of the container are fixed, and the container is not effectively connected to the semi-trailer beam. This connection method has obvious defects during vehicle driving. When the semi-trailer is driving on bumpy roads or making sharp turns, the container will generate lateral force and lateral displacement due to inertia, resulting in relative sliding between the bottom of the container and the semi-trailer frame. The occurrence of this sliding phenomenon is mainly because the fixed points around the bottom of the container cannot provide sufficient lateral restraint force and cannot effectively resist the displacement of the container under the action of lateral force. As the bottom of the container slides, its weight will be concentratedly transferred to the beam on one side of the semi-trailer, forming an uneven lateral load. Under the action of this load for a long time, the semi-trailer beam 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.

[0003] In order to solve the above problems, this application proposes a new energy container transport semi-trailer. Summary of the Invention

[0004] The present invention proposes a new energy container transport semi-trailer, which solves the problem in the related art that the existing container and semi-trailer installation method is only fixed on the bottom four sides and is not effectively connected to the beam. During driving, the container generates lateral force and lateral displacement due to inertia, causing the bottom and the frame to slide relative to each other. The sliding causes the weight to be concentratedly transferred to one side of the beam, forming an uneven load, which can easily cause the beam to deform, and the sliding friction will weaken the fixing effect and life of the lock.

[0005] The present invention proposes a new energy container transport semi-trailer, comprising a semi-trailer body and a container body hoisted above the semi-trailer body; Two main beams are installed on the semi-trailer body, multiple cross beams are installed between the two main beams, loading blocks are installed in the cross beams, two slots are symmetrically opened in the loading blocks, and multiple groups of inclined blocks are installed at the bottom of the box body, each group of inclined blocks corresponds to the two slots in the loading block; Two positioning push components are provided in the crossbeam, and limiting components cooperating with the positioning push components are installed on the two main beams.

The bottom of the force rod is installed with a force 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 block.

[0010] As a further optimization scheme of the present invention, the protective assembly includes a protective part and a pneumatic support part. The outer sides of the two main beams are provided with a protective part. The bottom of the protective part is installed with a pneumatic support part fixed to the main beam, and the pneumatic support part cooperates with the first clamping block.

[0011] As a further optimization scheme of the present invention, the protective part includes a strip and a protective rod. The outer sides of the two main beams are provided with a strip, the strip is connected to the pneumatic top support, and a plurality of protective rods arranged at intervals are installed on the strip. Side ear frames are installed on both sides of the box body, and openings adapted to the strip are opened in the two side ear frames. A rope hole is opened at the top of the protective rod, and a rope frame is installed on the top of the box body.

[0012] As a further optimization scheme of the present invention, the pneumatic support component includes a fixed cylinder, an air cylinder and a conduit. The outer sides of the two main beams are installed with fixed cylinders, and elastic support parts are installed in the two fixed cylinders, and the top ends of the elastic support parts pass through the tops of the fixed cylinders. The two bars are respectively installed on the two elastic support parts. The bottom of the fixed cylinder is connected to the air cylinder opposite to the first block through a conduit, and the air cylinder is fixedly connected to the main beam. A first piston is slidably arranged in the air cylinder, and the outer end of the first piston is installed with a shaft connected to the first block.

[0013] As a further optimization scheme of the present invention, the elastic supporting part includes a supporting rod, a second piston and a third spring.

[0014] As a further optimization solution of the present invention, cylindrical locks are installed at both ends of the two main beams, and concave holes are opened around the bottom of the box body, and the concave holes are adapted to the cylindrical locks.

[0015] The above technical solution of the present invention has the following beneficial technical effects: The first and second clamping blocks are engaged with the first and second clamping blocks respectively, and the first and second clamping blocks are engaged with the second and second clamping blocks respectively, so as to fix the middle part of the bottom surface of the box body. The above-mentioned design can effectively limit the lateral displacement of the middle part of the bottom surface of the box body, thereby providing a stronger lateral restraint force for the container, avoiding the lateral displacement caused by inertia during the driving of the vehicle, and this structural design makes the connection between the middle part of the bottom surface of the box body and the semi-trailer body tighter and more stable, thereby enhancing the overall connection strength between the box body and the semi-trailer body and improving the fixing stability. 2. When the two first clamping blocks located in the cross beam of the present invention move outward, the elastic push piece connected to the first clamping block can push the limit assembly upward, so that the limit assemblies on the two main beams are respectively inserted into the two grooves on both sides of the bottom of the box body, and then the electromagnet on the limit assembly is energized to make it magnetically connected with the magnetic blocks in the grooves to complete the fixation of the two sides of the bottom of the box body. The above design enables the weight of the box body to be more evenly distributed on the main beam of the semi-trailer body, avoiding the situation where the weight is concentratedly transferred to the main beam on one side of the semi-trailer body due to the sliding of the box bottom, thereby reducing the risk of deformation of the main beam of the semi-trailer body due to uneven load, and this double fixing method further enhances the connection strength between the bottom of the box body and the semi-trailer body, making the box body more stable during vehicle driving and able to effectively resist various external forces, and the power on and off of the electromagnet can flexibly control the fixing state between the limit assembly and the box, which is convenient for quickly releasing the fixation or re-adjusting the fixed position when needed, thereby improving the flexibility and convenience of operation. 3. When the two first clamping blocks of the present invention move outward, they can respectively push the two guard assemblies to move upward, extending the length protection distance on both sides of the box body. Subsequently, one end of a plurality of pull ropes can be fixed to the top of the box body, and the other end can be connected to the guard assemblies on the outside of the two main beams, so that the pull ropes can pull and fix the guard assemblies to maintain the position of the first clamping block, so that the positioning pushing assembly can achieve stable limiting of the inclined block at the bottom of the box body, avoiding the displacement of the first clamping block and the second clamping block due to external force, which affects the fixing effect of the box body. In addition, the cooperation between the pull ropes and the guard assemblies can form a protective barrier on the outside of the box body, so as to play a role of protection and buffering when the side of the box body is hit, reduce the damage to the box body caused by the impact, and improve the safety of the box body during transportation; 4. The present invention assembles multiple sets of inclined blocks at the bottom of the box, which can enable the box to maintain a certain distance from the ground when it is hoisted and placed on the ground, avoiding direct contact between the box and the ground, thereby reducing the erosion and pollution of the bottom of the container caused by factors such as moisture and dirt on the ground, extending the service life of the container, and preventing some sharp objects on the ground from damaging the bottom of the box, reducing the risk of damage to the bottom of the box due to uneven ground or the presence of debris, ensuring the integrity and structural strength of the bottom of the box, and ensuring its normal use during subsequent transportation.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0019] like Figures 1-16 As shown, the present invention proposes a new energy container transport semi-trailer, comprising a semi-trailer body 1 and a container body 2 hoisted above the semi-trailer body; Two main beams 101 are installed on the semi-trailer body 1, and multiple cross beams 102 are installed between the two main beams 101. A loading block 103 is installed in the cross beam 102, and two slots 104 are symmetrically provided in the loading block 103. Multiple groups of inclined blocks 21 are installed at the bottom of the box body 2, and each group of inclined blocks 21 corresponds to two slots 104 in the loading block 103; Two positioning push components 3 are provided in the crossbeam 102, and the two main beams 101 are both equipped with a limit component 4 that cooperates with the positioning push component 3. Grooves 22 are provided on both sides of the bottom of the box body 2, and the two grooves 22 are respectively adapted to the two limit components 4; The outer sides of the two main beams 101 are both equipped with protective components 5 that cooperate with the positioning and pushing components 3; When the box 2 is hoisted, it moves downward along the protective component 5, and the inclined block 21 at the bottom thereof passes through the positioning pushing component 3 and is inserted into the slot 104. The positioning pushing component 3 is forced to move outward, pushing the limiting component 4 to move upward and insert into the groove 22 at the bottom of the box 2, and pushing the two protective components 5 to move upward to protect both sides of the box 2.

[0020] When the box body 2 is hoisted by the present invention, it can be moved downward along the protective component 5, and the inclined block 21 at the bottom is inserted into the slot 104 of the loading block 103 through the positioning pushing component 3. During this process, the inclined block 21 forces the positioning pushing component 3 to move outward, and then pushes the two limit components 4 to move upward and insert them into the two grooves 22 at the bottom of the box body 2 respectively, and at the same time pushes the two protective components 5 to move upward to form protection on both sides of the box body 2. The above realizes the connection between the two sides of the bottom of the box body 2 and the two main beams 101 on the semi-trailer body 1, and also realizes the connection to the middle part of the bottom surface of the box body 2, thereby ensuring the stability of the box body 2 during transportation.

[0021] In this embodiment, the card push component 3 includes a first card block 31, a second card block 32, a slider 33 and an elastic push piece 34. The first card block 31 and the second card block 32 located in the beam 102 are provided above the two slots 104. Slides 105 are provided on both sides of the beam 102. Sliders 33 are fixed on both sides of the first card block 31 and the second card block 32. The two sliders 33 are respectively slidably matched with the two slides 105. The two first card blocks 31 are respectively matched with the two protective components 5. The two first card blocks 31 are installed with elastic push pieces on the side away from each other. Push piece 34, two elastic push pieces 34 are respectively matched with two limit assemblies 4, an insertion area for the inclined block 21 to pass through is formed between the first card block 31 and the second card block 32, and a first inclined surface is formed on the adjacent side of the first card block 31 and the second card block 32. The number of each group of inclined blocks 21 is two and they are arranged symmetrically. The two inclined blocks 21 are inclined from both sides of the box body 2 to the middle thereof and match with the first inclined surfaces on the first card block 31 and the second card block 32. A loading hole is opened on the adjacent side of the first card block 31 and the second card block 32, and a pressure sensor 35 is installed in the loading hole.

[0022] When the inclined block 21 at the bottom of the box body 2 moves downward, it passes through the insertion area formed between the first block 31 and the second block 32. Since the two inclined blocks 21 of each group of inclined blocks 21 are inclined from both sides of the box body 2 to the middle, their inclined surfaces will contact the first inclined surfaces on the adjacent sides of the first block 31 and the second block 32 and generate a force. Under this force, the first block 31 and the second block 32 will slide outward along the sliding opening 105 on the beam 102 through the sliders 33 on both sides. At the same time, the two first blocks 31 are separated from each other. The elastic push piece 34 on one side pushes the limit assembly 4 to move upward and is inserted into the groove 22 at the bottom of the box body 2. When the first card block 31 moves outward, it pushes the protective assembly 5 to move upward, extending the protective length on both sides of the box body 2. The pressure sensors 35 in the loading holes on the first card block 31 and the second card block 32 can monitor the lateral force exerted on the inclined block 21 during transportation, and can also monitor the contact status between the inclined block 21 and the first card block 31 and the second card block 32 in real time, so as to judge whether the box body 2 is installed in place.

[0023] In this embodiment, the elastic push member 34 includes a fixed rod 341, a push block 342 and a first spring 343. The two first blocks 31 are each installed with a fixed rod 341 at one end away from each other. The two fixed rods 341 slide through the two ends of the two beams 102 respectively. The two fixed rods 341 are each installed with a push block 342 at one end away from each other. The two push blocks 342 slide through the two main beams 101 respectively. The two push blocks 342 cooperate with the two limit assemblies 4. The first spring 343 is sleeved on the fixed rod 341, and the two ends of the first spring 343 are respectively connected to the first block 31 and the inner wall of the beam 102.

[0024] When the first clamping block 31 moves outward under the action of the inclined block 21, the fixed rod 341 connected thereto moves outward synchronously. Since the fixing rod 341 slides through the two ends of the cross beam 102, its movement pushes the pushing block 342 at the end to slide along the main beam 101. During this process, the first spring 343 sleeved on the fixing rod 341 is compressed due to the relative movement of the first clamping block 31 and the inner wall of the cross beam 102, and the pushing block 342 contacts the limit assembly 4 during the sliding process, thereby transmitting the lateral movement force of the first clamping block 31 to the limit assembly 4, causing it to move up and insert into the groove 22 at the bottom of the box body 2. The above design realizes the transmission of force from the positioning pushing assembly 3 to the limit assembly 4, providing power for the action of the limit assembly 4. The elastic action of the first spring 343 not only assists the first clamping block 31 to reset when the box body 2 is disassembled, but also buffers the lateral impact force received by the first clamping block 31 during transportation, thereby enhancing the stability and durability of the structure.

[0025] In this embodiment, the limit assembly 4 includes a limit block 41 and an elastic force-bearing member 42. A placement opening is opened at the top of the two main beams 101, and a limit block 41 is set in the two placement openings. The two limit blocks 41 are respectively adapted to the 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 limit block 41. The bottom of the two limit blocks 41 is connected to the elastic force-bearing member 42, and the two elastic force-bearing members 42 are respectively matched with the two push blocks 342.

[0026] When the push block 342 of the elastic push piece 34 moves outward, it will contact the elastic force-bearing piece 42 of the limit assembly 4 and apply a force. Under this force, the elastic force-bearing piece 42 pushes the limit block 41 to move upward until the limit block 41 is inserted into the corresponding groove 22 at the bottom of the box body 2. At this time, the magnetic block 221 installed in the groove 22 and the electromagnet 411 installed on the limit block 41 are close to each other, and the electromagnet 411 is energized to generate magnetism, thereby realizing a magnetic connection with the magnetic block 221, thereby stably fixing the limit block 41 in the groove 22. The above design drives the limit 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, to form a double fixation, thereby enhancing the connection strength between the two sides of the bottom of the box body 2 and the main beam 101, effectively limiting the lateral and longitudinal displacement of the box body 2, and the on and off of the electromagnet 411 can flexibly control the fixed state, facilitate the loading and unloading operations of the box body 2, and improve the convenience of use.

[0027] 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 with the force-bearing rod 421 that extends into the placement port and is connected to the limit block 41. The bottom of the force-bearing rod 421 is installed 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 block 422. When the push block 342 moves outward under the drive of the elastic push member 34, the second inclined surface on the push block 342 will contact the third inclined surface at the bottom of the force 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-bearing member. The vertical upward force of block 422 prompts the force block 422 to drive the force rod 421 to move upward. The upward movement of the force rod 421 will simultaneously drive the limit block 41 to move upward along the placement port. During this process, the second spring 423 is compressed to store elastic potential energy. The above design converts the horizontal driving force into a vertical driving force through the force conversion effect of the inclined surface, ensuring that the limit block 41 can move upward smoothly and insert into the groove 22 at the bottom of the box body 2, ensuring the reliable realization of the fixing function of the limit assembly 4. The setting of the second spring 423 can not only assist the force block 422, the force rod 421 and the limit block 41 to reset when the push block 342 is reset, but also buffer the impact of external vibration on the limit structure during transportation, thereby enhancing the stability and service life of the overall structure.

[0028] In this embodiment, the protective component 5 includes a protective part 51 and a pneumatic support part 52. The outer sides of the two main beams 101 are provided with protective parts 51. The bottom of the protective part 51 is installed with a pneumatic support part 52 fixed to the main beam 101, and the pneumatic support part 52 cooperates with the first clamping block 31; when the first clamping block 31 in the clamping pushing component 3 moves outward, it will generate a thrust on the pneumatic support part 52 in the protective component 5. Under the action of this thrust, the pneumatic support part 52 starts and generates an upward thrust, pushing the protective part 51 to move upward along the outer side of the main beam 101, thereby extending the protection length of the protective part 51 on both sides of the box body 2, and enhancing the protection coverage of the side of the box body 2.

[0029] In this embodiment, the protective member 51 includes a strip 511 and a protective rod 512. The outer sides of the two main beams 101 are provided with a strip 511, the strip 511 is connected to the pneumatic top support member 52, and a plurality of protective rods 512 arranged at intervals are installed on the strip 511. Side ear frames 24 are installed on both sides of the box body 2. The two side ear frames 24 are provided with openings adapted to the strip 511. The top of the protective rod 512 is provided with a rope hole, and the top of the box body 2 is provided with a rope frame 25; when the pneumatic top support member 52 is actuated, it will push the strip 511 in the protective member 51 to move upward, and the strip 511 drives the multiple protective rods 512 installed thereon to move upward synchronously. At this time, the side ear frames 24 on both sides of the box body 2 are aligned with the strip 511. In response, the bar 511 will enter the opening in the side ear frame 24 during the upward movement, and achieve cooperation 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 protection component 5 and the box 2 are pulled and fixed by the pull rope. The cooperation between the bar 511 and the side ear frame 24 enhances the connection between the protection component 5 and the box 2. After the protective rod 512 moves upward, the side protection range is expanded. The pull rope is connected through the rope hole and the rope frame 25, which further strengthens the position of the protection component 5 and can also limit the position of the card push 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.

[0030] It should be noted that when the box body 2 of the present invention is installed, the side ear frames 24 on both sides can be respectively mounted on the protection rods 512 of the two protection components 5, so that it moves downward along the protection rods 512 and plays a guiding role through the protection rods 512.

[0031] In this embodiment, the pneumatic support member 52 includes a fixed cylinder 521, an air cylinder 522 and a conduit 523. The outer sides of the two main beams 101 are each installed with a fixed cylinder 521, and an elastic support portion 524 is each installed in the two fixed cylinders 521, and the top of the elastic support portion 524 passes through the top of the fixed cylinder 521. The two strips 511 are respectively installed on the two elastic support portions 524, and the bottom of the fixed cylinder 521 is connected to the air cylinder 522 opposite to the first clamping block 31 through the conduit 523, and the air cylinder 522 is fixedly connected to the main beam 101, and a first piston 5221 is slidingly arranged in the air cylinder 522, and the outer end of the first piston 5221 is installed with a shaft 5222 connected to the first clamping block 31.

[0032] When the first block 31 in the positioning pushing assembly 3 moves outward, it will push the shaft 5222 in the air cylinder 522, so that the shaft 5222 drives the first piston 5221 to slide in the air cylinder 522. The sliding of the first piston 5221 presses the gas in the air cylinder 522 into the fixed cylinder 521 through the conduit 523. The air pressure in the fixed cylinder 521 increases, and then pushes the internal elastic supporting part 524 to move upward. The top of the elastic supporting part 524 passes through the top of the fixed cylinder 521, driving the protective part 51 connected thereto to move up synchronously. The above design converts the lateral displacement of the first 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 up synchronously with the installation action of the box body 2 in time, effectively expanding the protection range on both sides of the box body 2.

[0033] In this embodiment, the elastic supporting portion 524 includes a supporting rod 5241, a second piston 5242 and a third spring 5243. The fixed cylinder 521 is slidably connected with the supporting rod 5241 inserted therein, and the bottom end of the supporting rod 5241 is installed with the second piston 5242 located in the fixed cylinder 521. The third spring 5243 is sleeved on the supporting rod 5241, and the two ends of the third spring 5243 are respectively connected to the second piston 5242 and the top wall of the fixed cylinder 521. The top of the fixed cylinder 521 is provided with an air hole 5211 for discharging gas when the second piston 5242 moves upward, and the bar 511 is installed at the top of the two supporting rods 5241.

[0034] When gas is introduced into the fixed cylinder 521 through the conduit 523 and the gas pressure increases, an upward thrust is generated on the second piston 5242. Under the action of this thrust, the second piston 5242 moves upward along the inner wall of the fixed cylinder 521, driving the supporting rod 5241 connected thereto to move upward synchronously, and the bar 511 at the top of the supporting rod 5241 rises accordingly. At the same time, the third spring 5243 sleeved on the supporting 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 third spring 5243 at the third piston 5242 in the fixed cylinder 521 is compressed. The gas above the second piston 5242 is discharged through the air hole 5211 opened at the top, avoiding the normal movement of the second piston 5242 affected by the accumulated gas pressure. The above design can achieve the smooth rise of the support rod 5241, thereby driving the protective part 51 to move up reliably, ensuring the effective expansion of the protection range. The setting of the air hole 5211 balances the air pressure in the fixed cylinder 521, ensuring the smooth movement of the elastic support part 524, and the third spring 5243 can assist the second piston 5242 and the support rod 5241 to reset when the air pressure decreases, thereby improving the flexibility and reusability of the structure.

[0035] In this embodiment, cylindrical locks 106 are installed at both ends of the two main beams 101, and recessed holes 23 are provided 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 lifted and moved down along the protective assembly 5 and gradually aligned with the semi-trailer body 1, the cylindrical locks 106 installed at both ends of the main beams 101 will be aligned with the recessed holes 23 provided around the bottom of the box body 2. As the box body 2 continues to move downward, the cylindrical locks 106 will gradually be inserted into the corresponding recessed holes 23, and the four corners of the box body 2 will be fixed by mechanical plug-in. This is the existing technology and will not be elaborated on in detail. It will cooperate with other fixed structures to form an all-round constraint on the box body 2.

[0036] The specific working principle of the present invention is as follows: When the box body 2 is hoisted, it first moves downward along the protective assembly 5. The oblique block 21 at the bottom passes through the insertion area formed by the first clamping block 31 and the second clamping block 32 in the positioning and pushing assembly 3. The inclined surface of the oblique block 21 cooperates with the first inclined surfaces of the first clamping block 31 and the second clamping block 32, pushing the two to slide outward along the sliding opening 105 of the crossbeam 102 through the slider 33. The oblique block 21 is finally inserted into the slot 104 of the loading block 103. When the first clamping block 31 moves, the fixed rod 341 and the pushing block 342 of the elastic pushing member 34 are driven to move. The pushing block 342 cooperates with the third inclined surface of the force-bearing block 422 in the limiting assembly 4 through the second inclined surface, pushing the force-bearing 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 body 2. The magnetic block 221 in the groove 22 is magnetically connected to the electromagnet 411 on the limiting block 41. At the same time, the first clamping block 31 pushes the shaft 5222 and the first piston 5221 of the pneumatic supporting member 52 to move in the gas cylinder 522. The gas enters the fixed cylinder 521 through the conduit 523, pushing the second piston 5242 and the supporting rod 5241 of the elastic supporting portion 524 upward, thereby driving the bar 511 and the protective rod 512 of the protective member 51 upward. The bar 511 enters the side ear frame 24, and the pull rope passes through the rope hole of the protective rod 512 and the rope frame 25 for fixation. In addition, the cylindrical locks 106 at both ends of the main beam 101 are inserted into the recessed holes 23 at the bottom of the box body 2 to achieve four-corner fixation; the various components work together to fix and protect the box body 2 from multiple positions and directions to ensure the stability and safety of the transportation process.

[0037] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
