Description

Technical Field

[0001] This invention relates to the field of precast concrete component transportation technology, specifically a precast component transportation shockproof packaging system. Background Technology

[0002] Precast flower boxes are mainly cement-based imitation wood greening containers, widely used in municipal roads and community landscaping. These precast flower boxes are durable and corrosion-resistant, made of reinforced concrete, and have a wood-grain finish. They overcome the problems of real wood being prone to rotting, insect infestation, and fading. They are not afraid of sun and rain, and their color is long-lasting and beautiful. Unlike wood, they do not need to be painted and maintained regularly. They have a long lifespan and are suitable for long-term outdoor placement.

[0003] like Figure 1 As shown, in existing technologies, the transportation of prefabricated flower box components typically involves painting and drying them, then manually arranging them neatly. During arrangement, straw ropes or other spacers are placed on each component to separate adjacent components and prevent damage from bumps and friction during transport. The entire assembly is then bundled together. This loading, arranging, and packaging process is labor-intensive and resource-intensive. During transport, the bottom of the components contacts the vehicle floor, and bumps and slippage can damage the components, causing edge or base damage that affects aesthetics. Damaged bases can also cause the flower boxes to land unevenly or crookedly, significantly impacting the yield rate. Upon arrival and unpacking, removing the outermost cable ties can cause the arranged prefabricated components to slide, spread out, or fall to the ground. This unpacking process is dangerous, posing a risk of bumps and knocks to construction workers. Furthermore, the risk of friction and collisions between the prefabricated components during this process is high, causing significant damage to both appearance and overall integrity. Based on this, the present invention designs a prefabricated component transportation shockproof packaging system to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a shockproof packaging system for transporting prefabricated components, in order to solve the problems mentioned in the background art, such as the labor-intensive and material-intensive process of manually arranging, bundling, loading, and packing components; the potential damage to components caused by bumps and slippage during transportation, resulting in damage to edges or bases that affects aesthetics; and the risk of collisions and other hazards to construction workers during unpacking at the site, as well as the significant risk of friction and collisions between prefabricated components during this process, which can cause considerable damage to appearance and integrity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated component transportation shockproof packaging system, comprising: a bottom pad, having a set of symmetrically arranged pads for padding the bottom of the prefabricated component; The back frame is fixedly connected to one end of the bottom pad, and the back frames are connected and fixed to the bottom pad through connectors; The bottom stop claws are evenly distributed in multiple sets and are rotatably connected to one side of the bottom pad in an upturned state. The front side of the upper end of the bottom stop claws is provided with a transition slope to facilitate the movement and pressing of the precast component. The bottom stop claws can spring back after being pressed down by the precast component.

[0006] As a further embodiment of the present invention, the inner side of the bottom pad is provided with a rotating shaft for connecting the bottom stop claw. The bottom stop claw is elastically rotatably connected to the outside of the rotating shaft by a torsion spring, or the inner side of the bottom pad is elastically rotatably connected with an opening plate. The opening plate is located below the bottom stop claw to keep the bottom stop claw in an upward-curved state.

[0007] As a further embodiment of the present invention, a gear sleeve is fixedly connected to one side of the bottom pawl, and a movable toothed plate is slidably connected to one side of the bottom pad. When the movable toothed plate moves down inside the gear sleeve, it drives the gear sleeve to rotate, causing the bottom pawl to rotate and rise. The top of the movable toothed plate is provided with an inclined angle plate that facilitates the pressing down of the preform. The movable toothed plate is initially located above the gear sleeve and does not mesh with it.

[0008] As a further embodiment of the present invention, a mounting base is fixedly connected to the inner side of the bottom pad, guide plates are fixedly connected to both sides of the movable toothed plate, a guide post is fixedly connected to the bottom of the mounting base, the guide post passes through the guide plate and is slidably connected to it, and a return spring for supporting the upward movement of the movable toothed plate is provided on the outer sleeve of the guide post.

[0009] As a further embodiment of the present invention, a roller guide rail is slidably connected to the other side of the bottom pad. A lifting cam is provided at the bottom of the roller guide rail. The lifting cam is rotatably connected between the mounting strips at both ends of the bottom pad through a camshaft. An extension rod is fixedly connected to one end of the camshaft. The extension rod is used to manipulate the rotation of the lifting cam to control the lifting and lowering of the roller guide rail. When the roller guide rail is raised, its top surface is higher than the top surface of the bottom pad. The extension rod is inserted and positioned into the back frame of the bottom pad through a roller insert rod.

[0010] As a further embodiment of the present invention, the connecting member is a fixed crossbar or scissor lift, and a retractable slide rail is fixedly connected to the inner side of the back frame. The bottom end of the scissor lift is rotatably connected to the back frame, and the upper end is slidably connected to the back frame through the retractable slide rail.

[0011] As a further embodiment of the present invention, a side frame is fixedly provided on the outer side of the back frame of the bottom pad, and a fixed side rod is provided at the front end of the side frame. The side frame and the end of the fixed side rod are fixed by a set of plug bolts. The fixed side rod is used to restrict the lateral movement of the prefabricated component.

[0012] As a further embodiment of the present invention, a plurality of inclined angle plates are rotatably connected to the top of the fixed side rod, and a plurality of positioning posts are fixedly connected to the top of the fixed side rod. The positioning posts are located on the side of the inclined angle plates to limit the straight edge of the inclined angle plates to be perpendicular to the fixed side rod. An elastic spring is fixedly connected between the positioning posts and the inclined angle plates.

[0013] As a further embodiment of the present invention, the front ends of the fixed side rods are fixed together by a barrier, and cylindrical head insert plates are fixedly connected to both ends of the barrier. The inner side of the fixed side rod is fixedly provided with a slot and a placement groove, the slot and the placement groove are connected, and the cylindrical head insert plate is guided downward into the placement groove through the slot, and the length of the cylindrical head of the cylindrical head insert plate is greater than the length of the placement groove.

[0014] As a further embodiment of the present invention, a ball bearing is provided on the rear side of the bottom stop claw, and a placement groove is provided in the bottom pad, and a protective pad is installed in the placement groove. The protective pad is a wooden board or a rubber board.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The raised bottom guards can be pressed down one by one by the transition slope. After the precast part passes the current bottom guard, it will automatically pop up and be located in front of the precast part. Therefore, the loading and arrangement process does not require one-time moving or hoisting to the position, which is conducive to the adjustment and arrangement after landing, reduces the precision requirements of hoisting and moving, shortens the time, improves efficiency, and at the same time reduces the control and precision requirements of moving or hoisting equipment, which helps to reduce costs.

[0016] This device simplifies the loading process. With the bottom pad supporting it, the bottom of the prefabricated component is off the ground or the floor of the truck during loading and transportation. Therefore, bumps and slippage during transportation will not damage the prefabricated component, which is conducive to the intact transportation of the prefabricated component.

[0017] After being untied upon arrival at the destination, the prefabricated components will not loosen instantly due to the obstruction of the bottom claws, thus avoiding damage or crushing injuries to the handling personnel during the loosening and sliding process, and improving the integrity and safety of the prefabricated components after transportation.

[0018] By adding fixed side bars to position the prefabricated components on both sides, lateral movement during transportation is prevented. When multiple shelves are arranged side by side, friction and collision between edges are avoided. In this solution, there is no need to add straps or other materials to secure the prefabricated components after loading and arranging. The prefabricated components can be pushed into the arrangement one by one. Therefore, there is no need to purchase straps, straw ropes, etc., and no need for manual or mechanical binding. The entire frame can also be reused, thereby reducing one-time investment and labor and machinery costs, improving the safety of the transportation process, and reducing collisions and wear.

[0021] Example 1

[0022] Please see Figure 1-12 The technical solution provided by the present invention is as follows: a prefabricated component transportation shockproof packaging system, comprising: a bottom pad 1, which is provided with a set of left and right symmetrical pads for padding the bottom of the prefabricated component; The back frame 2 is fixedly connected to one end of the bottom pad 1, and the bottom pad 1 is fixedly connected between the back frames 2 by connectors; The bottom stop 3 is evenly distributed with multiple sets and is rotatably connected to one side of the bottom pad 1 with the upper end raised. The front side of the upper end of the bottom stop 3 is provided with a transition slope 4 to facilitate the movement and pressing of the precast part. The bottom stop 3 can spring back after being pressed down by the precast part.

[0023] When the prefabricated components are arranged and loaded, they are placed on the bottom pad 1 at any position and then moved backward. During the movement, the raised bottom guards 3 can be pressed down one by one by the transition slope 4. When the prefabricated component passes the current bottom guard 3, it automatically bounces up and is located in front of the prefabricated component, so that it can move backward smoothly until the last position and fits with the back frame 2. Therefore, the loading and arrangement process does not require one-time moving or hoisting to the position, which is conducive to the adjustment and arrangement after landing, reduces the accuracy requirements of hoisting and moving, shortens the time, improves efficiency, and at the same time reduces the control and precision requirements of moving or hoisting equipment, which helps to reduce costs.

[0024] Since the bottom guard 3 is initially raised, it can block the front end of the prefabricated parts after they are arranged, preventing them from sliding. This helps stabilize the already arranged prefabricated parts, keeping them upright and preventing them from sliding easily, which is beneficial for the subsequent arrangement and loading of prefabricated parts.

[0025] After each precast component is loaded, each precast component is blocked by the bottom guard 3 at the front end, and a gap is formed between two precast components to prevent them from colliding and being damaged, without the need for isolation ropes or pads between each precast component.

[0026] After the prefabricated components are arranged and loaded, they can be uniformly fixed and packaged by attaching straps to the sides. The prefabricated components supported by the bottom pad 1 have sufficient distance between their bottom and the ground, which also facilitates front and rear binding and fixing through the bottom of the prefabricated components.

[0027] This device simplifies the loading process. With the bottom pad 1 supporting it, the bottom of the precast component is off the ground or the floor of the truck during loading and transportation. Therefore, bumps and slippage during transportation will not damage the precast component, which is conducive to the intact transportation of the precast component.

[0028] Meanwhile, after being untied upon arrival at the destination, the prefabricated components will not loosen instantly due to the obstruction of the bottom claw 3, thus avoiding damage or crushing injuries to the handling personnel during the loosening and sliding process, and improving the integrity and safety of the prefabricated components after transportation.

[0029] As a further embodiment of the present invention, the inner side of the bottom pad 1 is provided with a rotating shaft 5 for connecting the bottom pawl 3. The bottom pawl 3 is elastically rotatably connected to the outside of the rotating shaft 5 by a torsion spring, or the inner side of the bottom pad 1 is elastically rotatably connected with an opening plate 6. The opening plate 6 is located below the bottom pawl 3 to keep the bottom pawl 3 in an upward-curved state.

[0030] The raised state of the upper end of the bottom stop 3 is maintained by the elastic force of the torsion spring sleeved on the rotating shaft 5. The principle of this scheme is the same as that of the clamp. When the preform passes the bottom stop 3, the elastic force of the torsion spring will lift the bottom stop 3 to maintain the raised state of the upper end.

[0031] The raised state of the upper end of the bottom stop 3 can also be maintained by the bottom opening plate 6. A spring sheet can be provided between the opening plate 6 and the bottom pad 1, or a torsion spring can be provided between the pivot of the opening plate 6 and the bottom pad 1. Based on this, the bottom stop 3 is located above the opening plate 6. When the bottom stop 3 is pressed down by the precast part, the opening plate 6 is also pressed down by the bottom stop 3. After the precast part 3 passes the bottom stop 3, it is opened back by the opening plate 6, which in turn lifts the bottom stop 3 to maintain the raised state of the upper end of the bottom stop 3, thereby blocking the precast part that passes by. With the opening plate 6 providing a way to restore the raised state, the rotation of the bottom stop 3 is more flexible, which is conducive to the subsequent rotation and uprighting of the bottom stop 3.

[0032] As a further embodiment of the present invention, a gear sleeve 7 is fixedly connected to one side of the bottom pawl 3, and a movable toothed plate 8 is slidably connected to one side of the bottom pad 1. When the movable toothed plate 8 moves down inside the gear sleeve 7, it drives the gear sleeve 7 to rotate, causing the bottom pawl 3 to rotate and rise. The top of the movable toothed plate 8 is provided with an inclined angle plate 9 that is conducive to pressing down the preform. The movable toothed plate 8 is initially located above the gear sleeve 7 and does not mesh with it.

[0033] To enhance the blocking effect of the bottom baffle 3 and ensure that the precast components remain upright and do not tip over during transport, taking the precast component moving backward to the position where it fits against the back frame 2 as an example, the precast component passes through the transition ramp 4 one by one to press down the bottom baffle 3 and smoothly reach the position where it fits against the back frame 2. At this time, the innermost moving toothed plate 8 is pressed down by the precast component. During the pressing down of the moving toothed plate 8, the gear sleeve 7 is driven to rotate, which in turn drives the bottom baffle 3 to rotate and stand upright, thus standing in front of the precast component in a more vertical or upright state. This provides better restriction for the precast component, and the anti-tipping effect of the precast component is better than the initial tilted state after standing upright. Since the weight of the precast component is pressed on the moving toothed plate 8, it is more reliable and powerful to keep the bottom baffle 3 in a vertical state. When the precast components are unloaded one by one, the remaining precast components can be kept in a good upright state on the bottom pad 1.

[0034] The movable toothed plate 8 and gear sleeve 7 are positioned relatively far back, so that when the preform moves, it can pass over the bottom stop 3 and press down the movable toothed plate 8, which is conducive to the rotation and uprighting of the bottom stop 3. Since the bottom stop 3 has a certain upward angle in its initial state, the movable toothed plate needs to move down to a smaller extent, so it can be achieved without setting a wider movable toothed plate 8. On this basis, the bottom stop 3 has a ball bearing 31 at the back end, which does not generate hard friction with the surface of the preform during the rotation and uprighting process, thereby protecting the surface of the preform.

[0035] The inclined angle plate 9 facilitates the precast component to press down the moving toothed plate 8 during movement. In the initial state, the moving toothed plate 8 does not mesh with the gear sleeve 7. Therefore, when the precast component presses down the bottom pawl 3, the moving toothed plate 8 will not be lifted up, thus allowing it to move smoothly.

[0036] As a further embodiment of the present invention, a mounting base 10 is fixedly connected to the inner side of the bottom pad 1, guide plates 11 are fixedly connected to both sides of the movable toothed plate 8, a guide post 12 is fixedly connected to the bottom of the mounting base 10, the guide post 12 passes through the guide plate 11 and is slidably connected to it, and a return spring 13 for supporting the upward movement of the movable toothed plate 8 is provided on the outer sleeve of the guide post 12.

[0037] After the precast component is unloaded, the bottom stop 3 can return to its upward-curved state under its own weight, which is convenient for reuse. In order to ensure that the process is smoother, the return spring 13 is compressed when the moving toothed plate 8 moves down. After the precast component is unloaded, the pressure above the moving toothed plate 8 is lost, and the return spring 13 bounces the moving toothed plate 8 up, thereby assisting the bottom stop 3 to rotate back to its initial state.

[0038] Example 2

[0039] Please see Figure 2-5 As a further optimization of Embodiment 1, a roller guide rail 14 is added. When the prefabricated parts are loaded and arranged one by one, the prefabricated parts can move smoothly and quickly along the roller guide rail 14 without rubbing against the bottom pad 1, thus reducing the difficulty of movement.

[0040] A roller guide rail 14 is slidably connected to the other side of the bottom pad 1. A lifting cam 15 is provided at the bottom of the roller guide rail 14. The lifting cam 15 is rotatably connected between the mounting strips 16 at both ends of the bottom pad 1 via a camshaft. An extension rod 17 is fixedly connected to one end of the camshaft. The extension rod 17 is used to operate the lifting cam 15 to rotate, thereby controlling the lifting and lowering of the roller guide rail 14. When the roller guide rail 14 is raised, its top surface is higher than the top surface of the bottom pad 1. The extension rod 17 is inserted and positioned into the back frame 2 of the bottom pad 1 via a roller insert rod 18.

[0041] The specific principle is as follows: before the prefabricated components are loaded and arranged, the lifting cam 15 is rotated by the extension rod 17 so that its protrusion faces upward, pushing the roller guide rail 14 upward so that the top surface of the roller guide rail 14 is higher than the bottom pad 1. At the same time, the roller extension rod 17 is inserted into the back frame 2 through the roller extension rod 17 to fix the lifting cam 15 so that its protrusion faces upward. When the prefabricated components are moved and arranged, they move on the roller guide rail 14 without contacting the bottom pad 1, thereby reducing the difficulty of movement and facilitating quick and neat arrangement. After use, the lifting cam 15 is rotated in the opposite direction by the extension rod 17 so that its protrusion faces downward, and the roller guide rail 14 falls down. At this time, all the prefabricated components fall down onto the bottom pad 1 without contacting the roller guide rail 14, and are stably placed on the bottom pad 1.

[0042] The extension rod 17 facilitates the operation of the lifting cam 15, thus saving effort.

[0043] Example 3

[0044] Please see Figure 7-8 As a further optimization of Embodiment 1, the bottom pads 1 can be fixed or movable. The movable connection of the bottom pads 1 facilitates storage after the prefabricated parts are unloaded.

[0045] As a further embodiment of the present invention, the connecting member is a fixed crossbar or scissor lift 19, and a retractable slide rail 20 is fixedly connected to the inner side of the back frame 2. The bottom end of the scissor lift 19 is rotatably connected to the back frame 2, and the upper end is slidably connected to the back frame 2 through the retractable slide rail 20.

[0046] Specifically, if it is a fixed type, it can be fixedly connected between the back frames 2 by a crossbar; if it is a movable type, it can be connected by a scissor lift 19. When the use is over, the scissor lift 19 is tightened, and the bottom pad 1 and the back frame 2 move closer together, which facilitates the folding after use; when in normal use, the scissor lift 19 is unfolded, so that the upper end of the scissor lift 19 slides to the bottom of the folding slide rail 20.

[0047] Example 4

[0048] Please see Figure 2-10 As a further optimization of Embodiment 1 or Embodiment 2, the prefabricated components are positioned on both sides by adding fixed side bars 22 to prevent lateral movement during transportation. When multiple shelves are arranged side by side, friction and collision between edges are avoided. In this solution, there is no need to add straps or other materials to fix the prefabricated components after loading and arranging. The prefabricated components can be pushed into the arrangement one by one. Therefore, there is no need to purchase straps, straw ropes, etc., and there is no need for manual or mechanical binding. The entire frame can also be reused, thereby reducing one-time investment and labor and mechanical costs, improving the safety of the transportation process, and reducing collisions and wear.

[0049] As a further embodiment of the present invention, a side frame 21 is fixedly provided on the outer side of the back frame 2 of the bottom pad 1, and a fixed side rod 22 is provided at the front end of the side frame 21. The side frame 21 and the fixed side rod 22 are fixed by a set of plug bolts 23. The fixed side rod 22 is used to restrict the lateral movement of the prefabricated component.

[0050] As a further embodiment of the present invention, a plurality of inclined angle plates 24 are rotatably connected to the top of the fixed side rod 22, and a plurality of positioning posts 25 are fixedly connected to the top of the fixed side rod 22. The positioning posts 25 are located on the side of the inclined angle plate 24 to limit the straight edge of the inclined angle plate 24 to be perpendicular to the fixed side rod 22. An elastic spring 26 is fixedly connected between the positioning post 25 and the inclined angle plate 24.

[0051] Specifically, when the precast component moves on the bottom pad 1, the edge of the precast component can squeeze and rotate the inclined corner plate 24 to make it close above the fixed side rod 22. The precast component can pass smoothly through the inclined corner plate 24 in sequence. When it reaches the appropriate position, it stops and stays in front of the inclined corner plate 24, thus blocking the edge of the precast component. The inclined corner plate 24 cannot rotate forward under the action of the positioning post 25. Therefore, the straight edge of the inclined corner plate 24 is kept flush with the precast component and limited to prevent the precast component from tilting forward. At the same time, the fixed side rod 22 fixes both sides. When the inclined corner plate 24 rotates, the elastic spring 26 contracts and deforms. After the precast component passes, the elastic spring 26 bounces the inclined corner plate 24 back to the original position blocked by the positioning post 25.

[0052] With the bottom stop 3 provided at the bottom of the precast component, a fixed side rod 22 and a beveled corner plate 24 are added to position and restrict the side of the precast component, thereby increasing the stability of the precast component during transportation.

[0053] As a further embodiment of the present invention, the front ends of the fixed side rods 22 are fixed together by a barrier 27. The two ends of the barrier 27 are fixedly connected with cylindrical head insert plates 28. The inner side of the fixed side rods 22 is fixedly provided with a slot 29 and a positioning groove 30. The slot 29 and the positioning groove 30 are connected. The cylindrical head insert plate 28 is guided downward into the positioning groove 30 through the slot 29, and the length of the cylindrical head of the cylindrical head insert plate 28 is greater than the length of the positioning groove 30.

[0054] After the prefabricated components are loaded and arranged, the guardrail 27 is placed at the front end of the fixed side bar 22, so that the cylindrical head plate 28 enters the slot 29 and slides along the slot 29 into the positioning groove 30. At this time, the guardrail 27 is just in contact with the frontmost prefabricated component, thereby positioning, guarding and fixing the front end of the prefabricated component after loading and arranging.

[0055] After being transported to the site, the component can be lifted up from the placement groove 30 and then slid out of the slot 29. The fixed side rod 22 can be removed by unscrewing the two plug bolts 23 at the rear end, which facilitates the removal of the prefabricated component.

[0056] As a further embodiment of the present invention, a ball bearing 31 is provided on the rear side of the bottom stop 3, and a placement groove is provided in the bottom pad 1. A protective pad 32 is installed in the placement groove. The protective pad 32 is a wooden board or a rubber board.

[0057] The protective pad 32 is replaceable. The protective pad 23 has a certain deformation and cushioning capacity, which provides a certain degree of protection for the prefabricated parts during transportation and avoids damage such as scratches and breakage.
