Description

Technical Field

[0001] This invention belongs to the field of construction loading and unloading technology, specifically a loading and unloading device for museum construction. Background Technology

[0002] Museums are generally non-profit, permanent institutions serving the public. They primarily research, collect, preserve, interpret, and display tangible and intangible cultural heritage. Open to the public, they are accessible and inclusive, offering a variety of experiences for education, appreciation, reflection, and knowledge sharing. During construction, to ensure excellent display of collections and showcase their style, and to provide a quiet environment for visitors, most museums often use high-quality PVC flooring. PVC flooring has advantages such as being lightweight, wear-resistant, environmentally friendly, slip-resistant, impact-resistant, flame-retardant, moisture-proof, and sound-absorbing, meeting the actual needs of museums.

[0003] Plastic flooring is often stored and transported in rolls wound on rollers, with each roll weighing over 50 kilograms. Initially, unloading and transporting these rolls from trucks to the construction site required manual labor, resulting in high physical exertion and potential shoulder and back injuries for workers. Later, roll-operated transport vehicles were widely adopted, saving time and effort. After unloading the rolls from the truck, they are placed upright on the ground, and then a worker pulls the roll, tilting it so that it rests against their shoulder. As the roll tilts, one side of the bottom of the roll lifts up. After setting a fixed height, another worker inserts the insert plate at the bottom of the roll material transport cart between the bottom of the roll material and the ground. Then, the roll material is pushed so that it rests against the load-bearing surface on the transport cart. At the same time, another worker holds the transport cart in place to prevent it from rolling backward when the roll material is heavy. Then, the workers push the transport cart loaded with the roll material to the construction site. One worker holds the transport cart while the other worker pulls the roll material to raise the bottom of the roll material again and gently moves the roll material so that the other worker can pull out the transport cart to complete the unloading. This improves the efficiency of loading and unloading the roll material and reduces labor intensity.

[0004] However, during the loading and unloading of the roll material using a transport vehicle, the roll material needs to be tilted so that one side of the bottom of the roll is raised to facilitate loading and unloading. However, after raising one side of the bottom of the roll material, due to the large mass of the roll material itself, the other side of the bottom is subjected to greater force, which can easily cause the other side of the roll material to be squeezed and deformed, affecting the paving effect of the ground during later construction. Especially in cold weather, the roll material is prone to hardening due to the low ambient temperature. When the force is uneven in a local area, the roll material is prone to cracking. Furthermore, when using a transport vehicle to transport the roll material to the construction site, only one roll can usually be transported at a time, reducing work efficiency. If multiple rolls need to be transported, they are often stacked together, which causes the bottom roll groove to be subjected to greater force and is prone to deformation.

[0005] In view of this, in order to improve the above-mentioned technical problems, the present invention provides a loading and unloading device for museum construction. Summary of the Invention

[0006] The problem this invention aims to solve is as follows: During the loading and unloading of roll materials using a transport vehicle, the roll material needs to be tilted so that one side of the bottom of the roll material is raised, which facilitates loading and unloading. However, after raising one side of the bottom of the roll material, due to the large mass of the roll material itself, the other side of the bottom is subjected to greater force, which can easily cause the other side of the roll material to be squeezed and deformed, affecting the paving effect of the ground during subsequent construction. Especially in cold weather, the roll material is prone to hardening due to the low ambient temperature. When the force is uneven in a local area, the roll material is prone to cracking. Furthermore, when using a transport vehicle to transport the roll material to the construction site, only one roll can often be transported at a time, reducing work efficiency. If multiple rolls need to be transported, they are often stacked together, which causes the bottom roll groove to be subjected to greater force, making it prone to deformation.

It also ensures that the roll materials remain parallel to the ground during loading and unloading, resulting in even stress distribution and preventing deformation or breakage due to excessive stress in certain areas. Furthermore, it allows for the simultaneous loading of multiple roll materials, reducing the number of trips to the construction site and improving work efficiency. The inclusion of a second guide plate ensures the roll materials are upright during loading, preventing tilting and potential safety hazards or damage during transport. The spacing between the two guide plates is adjustable via threaded rods, accommodating roll materials of different widths and enhancing the device's practicality. Finally, multiple roll materials are separated during loading and transmission, preventing excessive stress on the bottom roll material and further minimizing deformation during loading and unloading.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 , Figure 2 and Figure 4As shown, the present invention provides a loading and unloading device for museum construction, including a vehicle body 1. The vehicle body 1 facilitates the loading and transport of plastic flooring rolls to the construction site. The vehicle body 1 includes three parallel balancing plates 101, all of which are parallel to the ground. The three balancing plates 101 are divided into an upper balancing plate 101, a middle balancing plate 101, and a lower balancing plate 101 from top to bottom. Multiple support columns 102 are fixedly connected between the three balancing plates 101. Four support columns 102 are fixedly connected between the upper balancing plate 101 and the middle balancing plate 101, and between the middle balancing plate 101 and the lower balancing plate 101. The 02 are distributed at the four diagonal points of the balance plate 101. Each of the three balance plates 101 has a discharge port 103 for easy transport of the plastic flooring roll. Casters are installed on the lower surface of the lower balance plate 101 for easy movement of the vehicle body 1. Side plates 104 are fixedly connected to the two opposite sides of the balance plate 101. A loading and unloading mechanism 2 is installed on the vehicle body 1. The loading and unloading mechanism 2 is used for loading and unloading multiple rolls at once, and ensures even force distribution on the rolls during unloading. The loading and unloading mechanism 2 includes a transmission unit 21 and a receiving unit 22. The transmission unit 21 is used to transport the rolls using their own weight, and the receiving unit 22 assists in the transmission, ensuring even force distribution during transport and loading. The unloading process ensures balanced force distribution. Two sets of transmission units 21 are arranged longitudinally in a "V" shape. Each set consists of an upper transmission unit 21 and a lower transmission unit 21. The receiving unit 22 includes a first receiving component 221, a second receiving component 222, and a third receiving component 223. The first receiving component 221 is located above the upper transmission unit 21, the second receiving component 222 is located between the two transmission units 21, and the third receiving component 223 is located below the lower transmission unit 21. First, the worker moves the roll of material from the truck to the first receiving component 221, and then rotates the first receiving component 221. The rotating component causes the roll to fall onto the upper transmission unit 21. Then, the roll's own weight triggers the upper transmission unit 21 to work. When the roll moves to the second receiving component 222, the second receiving component 222 is rotated to transfer the roll to the lower transmission unit 21. Then, the roll's own weight is used again to transfer the roll to the bottom of the vehicle body 1 through the lower transmission unit 21. Finally, the third receiving component 223 is rotated to unload the roll from the vehicle body 1. There is no need for manual handling of the roll from the truck to the construction site, reducing labor intensity. At the same time, during the transfer of the roll, the roll is subjected to uniform force, avoiding uneven force and local compression deformation.

[0022] like Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, the transmission unit 21 includes an inclined first support block 211, which passes through the discharge port 103 of the upper balance plate 101. Multiple first support rods 212 are fixedly connected to the side of the first support block 211, and the first support rods 212 are fixedly connected to the side plate 104. Slots are provided at both ends of the first support block 211, and rotating wheels 213 are installed in the slots. The rotating wheels 213 are rotatably connected to the first support block 211. One of the two rotating wheels 213 is positioned near the upper balance plate 101, and the other is positioned near the middle balance plate 101. A first rotating shaft 214 passes through the rotating wheel 213, and the axis of the first rotating shaft 214 is parallel to the ground. The rotating wheel 213 is rotatably connected to the first rotating shaft 214, and the first rotating shaft 214 is fixedly connected to the side plate 104. A conveyor belt 215 is fitted onto two rotating wheels 213. The conveyor belt 215 is in contact with the surface of the first support block 211. The conveyor belt 215 wraps around the rotating wheels 213 and the first support block 211. Ball bearings are installed on the upper surface, lower surface and end face of the first support block 211 to reduce the friction between the conveyor belt 215 and the first support block 211. The first support block 211 is used to support the conveyor belt 215 and prevent the conveyor belt 215 from denting when the roll material falls on it. Multiple sets of force-bearing components 216 are evenly arranged on the conveyor belt 215. Each set of force-bearing components 216 includes multiple push blocks 2161. The multiple push blocks 2161 in each set of force-bearing components 216 are evenly arranged along the width direction of the conveyor belt 215. The push blocks 2161 are fixedly connected to the conveyor belt 215.

[0023] When the worker releases the roll of material through the rotating component in the first receiving assembly 221, the roll falls onto the conveyor belt 215 in the upper conveying unit 21, between every two sets of push blocks 2161. Due to the large weight of the roll, it moves downwards along the slope of the first support block 211. As the roll moves downwards, it pushes a set of push blocks 2161 located at the lower end of the roll. The push blocks 2161, under the pushing force, cause the conveyor belt 215 to rotate. When the roll moves down to the end face of the first support block 211, it detaches from the push blocks 2161 and the conveyor belt 215 in the upper conveying unit 21 due to gravity and enters the second receiving assembly 222. During the aforementioned downward movement of the roll, the conveyor belt 215 is pushed to rotate, thus... The pusher 2161 located below the conveyor belt 215 can be moved to above the conveyor belt 215, making it easier for the transmission unit 21 to carry and transmit the next roll of material. Therefore, the vehicle body 1 can load multiple rolls of material at one time without the need for manual handling over long distances or the need for excessive manpower when loading the rolls from the truck to the transport vehicle, thus reducing labor intensity. Furthermore, when the rolls are loaded onto the vehicle body 1, they are always in a position parallel to the conveyor belt 215 and the pusher 2161, and parallel to the ground, so that the rolls are evenly stressed during loading, preventing deformation or cracking. Moreover, multiple rolls are separated by the force-bearing component 216 to prevent the rolls from piling up and causing excessive stress on the minimum roll, which could lead to compression and deformation.

[0024] like Figures 1 to 7 As shown, the first receiving component 221 includes a first C-shaped plate 2211 disposed above the conveyor belt 215. The first C-shaped plate 2211 is located at the higher end of the first support block 211. A first mounting plate 2212 is fixedly connected to both sides of the first C-shaped plate 2211. A second rotating shaft 2213 is fixedly connected to the side of the first mounting plate 2212 away from the first C-shaped plate 2211. The center of the second rotating shaft 2213 is collinear with the center of the first C-shaped plate 2211 and the center of the first mounting plate 2212. The second rotating shaft 2213 passes through the side plate 1. 04 and rotates with the side plate 104. The end of the second rotating shaft 2213 is fixedly connected to the first handwheel 2214. The first C-shaped plate 2211 is provided with a first guide plate 2215 on the side away from the conveyor belt 215. In the initial state, the opening of the first C-shaped plate 2211 faces the first guide plate 2215. The second support block 2216 is fixedly connected to the bottom of the first guide plate 2215. The second support block 2216 is fixedly connected to the upper surface of the upper balance plate 101. An extension plate 2217 is fixedly connected to the side of the first guide plate 2215 away from the first C-shaped plate 2211.

[0025] When loading and unloading the rolls of material from the truck, the worker first pushes the truck body 1 to the truck bed, ensuring the lower surface of the extension plate 2217 is flush with the bottom of the truck bed. Next, the worker moves the rolls of material from inside the truck to the extension plate 2217 and then pushes them, causing them to slide along the extension plate 2217 and the first guide plate 2215 onto the first C-shaped plate 2211. The first C-shaped plate 2211 can only hold one roll of material at a time; the remaining rolls are arranged sequentially on the first guide plate 2215 and the extension plate 2217. Then, the worker turns the first handwheel 2214, which rotates... The second rotating shaft 2213 rotates, which in turn drives the first C-shaped plate 2211 to rotate. Because each roll of material is relatively heavy, when the first C-shaped plate 2211 is rotated by handwheel, it cannot drive the roll of material located on it to rotate; only the first C-shaped plate 2211 rotates. When the first C-shaped plate 2211 rotates, its opening faces the conveyor belt 215, and its back faces the guide plate 2215. The remaining rolls located on the guide plate 2215 and the extension plate 2... The roll material on 217 is blocked. At this time, the roll material on the first C-shaped plate 2211 falls from the opening of the first C-shaped plate 2211 under its own weight between every two sets of force-bearing members 216 on the conveyor belt 215. Because the first support block 211 is tilted, the roll material rolls downward due to its own weight. When the roll material rolls downward, it pushes the push block 2161, causing the push block 2161 to drive the conveyor belt 215 to rotate. When the roll material moves to the end position of the first support block 211, it disengages from the upper conveyor unit 21 and enters the second receiving assembly 222. When the previous set of roll material disengages from the first C-shaped plate 217, it falls from the opening of the first C-shaped plate 2211. After step 211, the worker rotates the handwheel in the reverse direction, causing the first C-shaped plate 2211 to rotate back to its initial position. This brings the opening of the first C-shaped plate 2211 back towards the first guide plate 2215, allowing the roll material on the first guide plate 2215 to slide onto the first C-shaped plate 2211 again. Then, the handwheel is rotated in the forward direction again to release the next roll material onto the conveyor belt 215. This process is repeated, allowing the vehicle body 1 to transport multiple roll materials on one side without manual handling, thus improving work efficiency, reducing labor intensity, and ensuring that the roll material is subjected to uniform force during loading and unloading.

[0026] like Figure 7 , Figure 8As shown, to prevent the roll material from falling directly onto the two conveyor belts 215 and being impacted when it detaches from the first receiving assembly 221 and the second receiving assembly 222, thus causing the roll material to crack, multiple guide rods 5 are evenly arranged on the two conveyor belts 215. A through groove 6 is provided on the push block 2161, through which the guide rods 5 pass. The guide rods 5 consist of both straight and curved parts. The guide rod 5 located on the upper conveyor belt 215 in the upper conveyor unit 21 has a curved section near the first guide plate 2215. The guide rod 5 is parallel to the transmission belt 215 and is a straight rod. The guide rod 5 located between the transmission belt 215 in the lower transmission unit 21 and the transmission belt 215 in the upper transmission unit 21 has an arc-shaped section near the second receiving component 222. The part of the guide rod 5 parallel to the transmission belt 215 in the lower transmission unit 21 is a straight rod. This facilitates the buffering and guidance of the roll material that is detached from the first receiving component 221 and the second receiving component 222, and prevents the roll material from falling directly and deforming and breaking when loaded on the vehicle body 1.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, to prevent the roll material from becoming misaligned during loading, which could cause jamming or collision between the roll material and the device, resulting in cracking or deformation, a second guide plate 7 is provided on both sides of the extension plate 2217. The second guide plate 7 is an arc-shaped structure, and the lower surface of the second guide plate 7 overlapping with the extension plate 2217 is flush with the lower surface of the extension plate 2217. The ends of the two second guide plates 7 away from the first C-shaped plate 2211 are open. When loading and unloading the roll material from the truck, the roll material is first placed between the two second guide plates 7, and then pushed along the arc of the two second guide plates 7 towards the first guide plate 2215. The roll material is straightened by the limit of the two second guide plates 7, preventing misalignment during loading and further preventing deformation and cracking of the roll material during loading.

[0028] like Figure 6 As shown, due to the weight of the roll material, a large amount of friction needs to be overcome when pushing it from the extension plate 2217 to the first guide plate 2215. Therefore, mounting grooves 8 are provided on the opposite sides of the two second guide plates 7. Multiple fixed shafts 9 are evenly arranged in the mounting grooves 8. The fixed shafts 9 are fixedly connected to the second guide plates 7. Rollers 10 are sleeved on the fixed shafts 9 and are rotatably connected to the fixed shafts 9. When the roll material is straightened between the two second guide plates 7, it contacts the rollers, reducing the contact area between the roll material and the second guide plates 7. At the same time, the rollers 10 further reduce the friction between the roll material and the second guide plates 7, making it easier to load and unload the roll material and further reducing the workload.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, due to varying construction site areas and the fact that museums often have different shapes for each exhibition room to enhance the display effect of exhibits, the required roll width also varies. Therefore, a through hole 11 is provided on the second support block 2216. The axis of the through hole 11 is parallel to the axis of the second rotating shaft 2213. The through hole 11 penetrates both sides of the second support block 2216. A threaded rod 12 is installed inside the through hole 11. The threaded rod 12 does not contact the wall of the through hole 11. Both ends of the threaded rod 12 are rotatably connected to the side plate 104. One end of the threaded rod 12 penetrates the side plate 104. A motor 13 is fixedly installed on the side plate 104. The motor 13 is a forward and reverse reversible motor 13 in the prior art. The output shaft of the motor 13 is fixedly connected to the threaded rod 12 through a coupling. The threaded rod 12 has threads with opposite directions at both ends. The second guide plate 7 is installed on two sections of thread on the threaded rod 12. The second guide plate 7 is threadedly connected to the threaded rod 12, and the lower surface of the second guide plate 7 is slidably connected to the upper balance plate 101. Therefore, the worker can start the motor 13 through the controller. The output shaft of the motor 13 rotates, which drives the threaded rod 12 to rotate. Since the threaded rod 12 has two sections of thread with different directions of rotation, and the two guide plates are threadedly connected to the threaded rod 12 through the two sections of thread with different directions of rotation, and the second guide plate 7 is slidably connected to the upper balance plate 101, the two second guide plates 7 can move away from or closer to each other when the threaded rod 12 rotates in the forward and reverse directions, adjusting the distance between the two second guide plates 7. This allows the two second guide plates 7 to be used for rolls of different widths, further improving the practicality of the device.

[0030] like Figure 4 , Figure 5 and Figure 7As shown, the second receiving assembly 222 includes a second C-shaped plate 2221 disposed between the two conveyor belts 215. The second C-shaped plate 2221 is located on the side of the conveyor belt 215 away from the first C-shaped plate 2211. A second mounting plate 2222 is fixedly connected to both sides of the second C-shaped plate 2221. A third rotating shaft 2223 is fixedly connected to the side of the second mounting plate 2222 away from the second C-shaped plate 2221. The third rotating shaft 2223 passes through the side plate 104 and is rotatably connected to the side plate 104. A second handwheel 2224 is fixedly connected to the end of the third rotating shaft 2223. In the initial state, the opening of the second C-shaped plate 2221 faces the upper transmission unit 21. When the roll material on the upper transmission unit 21 moves to the end of the first support block 211, the roll material detaches from the first support block 11 and the conveyor belt 215 in the upper transmission unit 21 due to its own weight and falls into the second C-shaped plate 2221. The second C-shaped plate 2221 can only hold one roll material at a time. The remaining roll materials are distributed between every two force-bearing components 216 in the upper transmission unit 21 and on the first guide plate 2215. Then, the worker turns the second handwheel 2224, which drives the third rotating... When shaft 2223 rotates, the rotation of shaft 2223 drives the rotation of C-shaped plate 2221. At this time, due to the large weight of the roll material, the rotation of C-shaped plate 2221 cannot synchronously rotate the roll material on it. Therefore, the roll material on C-shaped plate 2221 remains stationary. When C-shaped plate 2221 rotates, it rotates the opening of C-shaped plate 2221 to face the lower transmission unit 21, thereby bringing the back of C-shaped plate 2221 closer to the transmission belt 215 in the upper transmission unit 21, blocking other roll materials on the upper transmission unit 21. Simultaneously, the roll material originally located on C-shaped plate 2221... The roll material in the template 2221 falls from the opening on the second C-shaped plate 2221 due to its own weight, detaches from the second C-shaped plate 2221, and falls onto the conveyor belt 215 in the lower transmission unit 21. Since the first support block 211 in the lower transmission unit 21 is also tilted, when the roll material falls onto the lower transmission unit 21, it continues to move downward due to its own weight, pushing the push block 2161 in the lower transmission unit 21 to drive the conveyor belt 215 to rotate. When the roll material moves to the lower end of the first support block 211 in the lower transmission unit 21, it detaches from the lower transmission unit 21 and enters the third receiving assembly 223.

[0031] When roll material is evenly distributed between every two force-bearing components 216 on the upper and lower transmission units 21, on the first C-shaped plate 2211 and the second C-shaped plate 2221, and on the first guide plate 2215, the vehicle body 1 completes the loading of the roll material. Then, the workers push the vehicle body 1 to transport the roll material to the construction site.

[0032] like Figure 4 , Figure 5 and Figure 7As shown, the third receiving component 223 includes a third C-shaped plate 2231 positioned below the lower transmission unit 21. The third C-shaped plate 2231 is located on the side of the conveyor belt 215 closest to the first C-shaped plate 2211. Third mounting plates 2232 are fixedly connected to both sides of the third C-shaped plate 2231. A fourth rotating shaft 2233 is fixedly connected to the side of the third mounting plate 2232 away from the third C-shaped plate 2231. The fourth rotating shaft 2233 passes through the side plate 104 and is rotatably connected to the side plate 104. A third handwheel 2234 is fixedly connected to the end of the fourth rotating shaft 2233. In the initial state, the opening of the third C-shaped plate 2231 faces the lower transmission unit 21. After the roll material detaches from the lower transmission unit 21, it falls into the third C-shaped plate 2231. The third C-shaped plate 2231 can only accommodate one roll material at a time. The remaining roll materials are distributed between every two force-bearing components 216 on the lower transmission unit 21. Between each pair of force-bearing components 216 in the middle, the second C-shaped plate 2221, the upper transmission unit 21, and the first guide plate 2215, the worker then turns the third handwheel 2234, which drives the fourth rotating shaft 2233 to rotate. The rotation of the fourth rotating shaft 2233 drives the third C-shaped plate 2231 to rotate. When the third C-shaped plate 2231 rotates, it cannot drive the roll material on it to rotate synchronously. Therefore, the roll material on the third C-shaped plate 2231 remains stationary. When the third C-shaped plate 2231 rotates, it can rotate the opening of the third C-shaped plate 2231 to face the ground, so that the back of the third C-shaped plate 2231 is close to the conveyor belt 215 in the lower transmission unit 21, blocking other roll materials on the lower transmission unit 21. At the same time, the roll material originally located in the third C-shaped plate 2231 falls to the ground from the opening on the third C-shaped plate 2231 due to its own weight, completing the unloading of the roll material.

[0033] During the process of the aforementioned roll material being loaded onto the truck body 1 from the truck bed and then unloaded from the truck body 1, the roll material is always in a parallel position to the ground, thus keeping the roll material in a balanced position. During loading and unloading, the force is evenly distributed, avoiding excessive force in some areas that could cause deformation or cracking. At the same time, during loading and unloading, there is no need for workers to push or pull the roll material, saving manpower. Furthermore, the multiple roll materials are distributed between each force-bearing component 216 and separated by push blocks 2161, preventing the roll material at the bottom from being subjected to greater pressure due to excessive accumulation of roll materials, which could cause deformation or cracking.

[0034] Meanwhile, to ensure that the openings of C-shaped plates 2211, 2221, and 2231 face correctly in the initial state, a first-order insertion hole can be made on handwheels 2214, 2224, and 2234. A second-order insertion hole is also made on the side plate 104 at the corresponding positions of handwheels 2214, 2224, and 2234. In the initial state, the opening of C-shaped plate 2211 faces the first guide plate 2215, and the opening of C-shaped plate 2221... The opening of the first C-shaped plate 2211 faces the upper transmission unit 21, and the opening of the third C-shaped plate 2231 faces the lower transmission unit 21. At this time, the insertion rod is passed through the first insertion hole and inserted into the second insertion hole to fix the first C-shaped plate 2211, the second C-shaped plate 2221, and the third C-shaped plate 2231. When releasing the roll material, the insertion rod is taken out, and then the first handwheel 2214, the second handwheel 2224, and the third handwheel 2234 are rotated to release the roll material, ensuring the receiving effect of the first C-shaped plate 2211, the second C-shaped plate 2221, and the third C-shaped plate 2231.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, in order to prevent the roll material on the lower transmission unit 21 from overflowing into the third C-shaped plate 2231 when it falls into the third C-shaped plate 2231, a limiting plate 14 is provided on the side of the third C-shaped plate 2231 away from the lower transmission unit 21. The limiting plate 14 is fixedly connected to the balance plate 101. The limiting plate 14 blocks the roll material, and together with the third C-shaped plate 2231, it can prevent the next roll material from rolling off when the roll material is released.

[0036] Working principle: When loading and unloading the rolls of material from the truck, the workers first push the truck body 1 to the truck bed, ensuring the lower surface of the extension plate 2217 is flush with the bottom of the bed. Then, the workers move the rolls of material from the truck one by one to the extension plate 2217. Next, they push the rolls so that they slide along the extension plate 2217 and the first guide plate 2215 onto the first C-shaped plate 2211. The first C-shaped plate 2211 can only hold one roll of material at a time; the remaining rolls are arranged sequentially on the first guide plate 2215 and the extension plate 2217. Then, the workers turn the first handwheel 2214, which drives the second rotating shaft 2213 to rotate. The second rotating shaft 2213 then drives the first C-shaped plate 2211 to rotate. Because each roll of material is relatively heavy, the rotation of the first handwheel... When the C-shaped plate 2211 is in operation, the first C-shaped plate 2211 cannot drive the roll material located on it to rotate. Only the first C-shaped plate 2211 rotates. When the first C-shaped plate 2211 rotates, its opening faces the conveyor belt 215, and its back rotates to the guide plate 2215, blocking the remaining roll material located on the guide plate 2215 and the extension plate 2217. At this time, the roll material on the first C-shaped plate 2211 falls from its opening due to its own weight between each pair of force-bearing members 216 on the conveyor belt 215. Because the first support block 211 is tilted, the roll material rolls downward due to its own weight. When the roll material rolls downward, it pushes the push block 2161, causing the push block 2161 to carry... As the conveyor belt 215 rotates, when the roll material moves to the lower end of the first support block 211, it detaches from the upper conveyor unit 21 and falls into the second C-shaped plate 2221. The second C-shaped plate 2221 can only hold one roll material at a time. The remaining roll materials are distributed between every two force-bearing components 216 in the upper conveyor unit 21 and on the first guide plate 2215. Then, the worker rotates the second handwheel 2224, which drives the third rotating shaft 2223 to rotate. The rotation of the third rotating shaft 2223 drives the second C-shaped plate 2221 to rotate. At this time, due to the greater weight of the roll material, the second C-shaped plate 2221 rotates until its opening faces the lower conveyor unit 21, thus bringing the back of the second C-shaped plate 2221 close to the conveyor belt 215 in the upper conveyor unit 21. Other rolls of material on element 21 obstruct the flow, while the rolls originally located in the second C-shaped plate 2221 fall from the opening on the second C-shaped plate 2221 under their own weight onto the conveyor belt 215 in the lower transmission unit 21. Since the first support block 211 in the lower transmission unit 21 is also tilted, when the rolls fall onto the lower transmission unit 21, their own weight causes them to continue moving downwards, pushing the push block 2161 in the lower transmission unit 21 to rotate the conveyor belt 215. When the rolls move to the end of the first support block 211 in the lower transmission unit 21, they detach from the lower transmission unit 21 and enter the third C-shaped plate 2231. When there is a roll of material between every two force-bearing members 216 in the transmission unit 21, and there are rolls of material in both the second C-shaped plate 2221 and the third C-shaped plate 2231,After loading the roll material onto the truck, the worker pushes the truck body 1 to the construction site and then turns handwheel 2234. Handwheel 2234 drives shaft 2233 to rotate, which in turn drives C-shaped plate 2231 to rotate. C-shaped plate 2231 rotates until its opening faces the ground, thus bringing its back side closer to the conveyor belt 215 in the lower conveyor unit 21. This blocks other roll materials on the lower conveyor unit 21, and the roll material originally located in C-shaped plate 2231 falls to the ground due to its own weight, completing the unloading of the roll material.
