Abstract
Description
Technical Field
[0001] The invention relates to the field of building component transportation, and in particular to an intelligent transportation frame for assembled building PC components. Background Art
[0002] Building PC components are precast concrete components. At the same time, intelligent transport racks for building PC components usually need to be assembled on trucks for transportation. Construction usually requires a large number of PC components because trucks have the advantages of flexibility, adaptability, efficiency, economy, safety and reliability. These advantages can ensure that PC components can be safely, promptly and efficiently transported to the construction site.
[0003] At present, the intelligent transport racks for building PC components on the market have some obvious disadvantages in dealing with bumpy road conditions of trucks. These disadvantages have brought many adverse effects on the transportation of building PC components. First of all, many traditional intelligent transport racks for building PC components lack effective shock-absorbing and buffering design. During the driving of trucks, especially when passing through bumpy sections, building components will directly bear the impact force from the road surface, and the building components cannot reasonably release the power generated by the bumps, which easily leads to collisions, wear and even damage between components. This not only increases the cost of repairing and replacing components, but may also affect the construction progress of the construction project, because the damaged components need to be re-produced or repaired, which delays time;
[0004] Secondly, the structure of traditional transport racks is often relatively fixed and lacks adaptive adjustment capabilities. They cannot automatically adjust according to different road conditions and bumps, and cannot provide stable support for building components. When facing complex and changing road conditions, the components will be subjected to excessive vibration and shaking due to the rigid fixation of the transport rack, increasing the risk of damage. Moreover, this fixed structure also limits the adaptability of the transport rack to different types of building components, and may require special adjustments and modifications for different components, increasing the cost of use and difficulty of operation.
[0005] In addition, some traditional transport racks use complex mechanical structures or electronic control systems to achieve a certain shock-absorbing effect. These complex designs not only increase the cost of the transport racks, but also increase the difficulty of maintenance and servicing. Once a failure occurs, professional technicians are required to repair it, which will lead to interruptions in transportation work and affect the progress of the construction project. At the same time, complex systems may also have reliability issues, and the risk of failure at critical moments is high.
[0006] At the same time, many traditional transport racks lack convenience during the loading process. Workers need to use additional tools or equipment to adjust the angle or position of the placement board, which increases the difficulty and complexity of loading. Moreover, due to the cumbersome operation, errors and mistakes are prone to occur, further reducing the accuracy and efficiency of loading. Secondly, traditional transport racks are usually unable to effectively avoid squeezing and collisions between building components. The components are tightly stacked together during transportation, and there is not enough gap to buffer vibrations and bumps, which makes the components vulnerable to damage, and the surface will show problems such as wear, deformation and even cracks. These damages will not only affect the quality and appearance of the building components, but also cause the components to be unable to be used normally and need to be repaired or replaced, increasing construction costs and the risk of delays in construction schedules.
[0007] Therefore, it is necessary to provide an intelligent transport rack for prefabricated building PC components to solve the above problems. Summary of the invention
[0008] In view of the deficiencies in the prior art, the object of the present invention is to provide an intelligent transport rack for assembled building PC components.
[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an intelligent transport rack for assembled building PC components, comprising a transport plate, a balancing component for assisting the smooth transportation of building PC components is arranged on the top of the transport plate, and an automatic stratification component for automatically discharging building PC components at intervals is arranged above the transport plate.
[0010] Preferably, the balancing assembly includes a positioning column group, which is fixedly connected to the top of the transport plate, and the top of the positioning column group is symmetrically fixedly connected with an arc block, the inner walls of two arc blocks are slidably connected with two limiting sliding columns, and the outer walls of the two limiting sliding columns are fixedly connected with a buffer plate.
[0011] Preferably, the balancing assembly further comprises a fixed rod group, the fixed rod group is fixedly connected to the top of the transport plate, and the top of the fixed rod group is rotatably connected with four arc-shaped limit buckles.
[0012] Preferably, the automatic stratification component includes a placement rack, which is fixedly connected to the top of the buffer plate, and a square groove is opened inside the placement rack. The bottom of the square groove is rotatably connected to a rotating column, and the outer wall of the rotating column is rotatably connected to the first placement plate and the second placement plate.
[0013] Preferably, the automatic stratification component also includes a limit bar, which is fixedly connected to the top of the first placement plate, and the interior of the limit bar is slidably connected to a working-shaped rotating rod, and a limit column is arranged above the second placement plate.
[0014] Preferably, both ends of the two limit sliding posts are provided with limit rings, and the four arc-shaped limit buckles are clamped on the two ends of the two limit sliding posts in a group of two.
[0015] Preferably, the first placement plate and the second placement plate are both configured to be L-shaped, and a weight-added block is provided at one end of the first placement plate and the second placement plate away from the placement frame, and the end of the I-shaped rotating rod away from the limit bar is rotatably connected to the inside of the weight-added block of the first placement plate.
[0016] Preferably, two second placement plates are provided, and the bottoms of the two second placement plates are rotatably connected to a I-shaped rotating rod.
[0017] The invention provides an assembled building PC component intelligent transport rack. Compared with the prior art, the invention has the following beneficial effects:
[0018] 1. Through the setting of the balancing component, after the transport plate is installed and fixed on the truck, when the truck passes through a bumpy road section, the building components loaded on the truck will shake. At this time, the limit sliding column slides along the arc block, which reasonably releases the power generated by the truck's bumping and avoids the damage of the building components loaded on the truck due to collision caused by bumps. Compared with the intelligent transport racks for building components on the market, the limit sliding column can slide smoothly on the arc block to adapt to different degrees of bumping amplitude. At the same time, the building components are easily directly subjected to rigid impact when the truck bumps. The design of the limit sliding column sliding along the arc block can convert the shaking power generated by the truck bumping into the displacement of the sliding column on the arc path. Through this displacement, the bumping energy is effectively absorbed and buffered, which greatly reduces the impact force on the components and reduces the risk of collision damage;
[0019] Secondly, traditional transport racks usually use fixed support structures and cannot be adaptively adjusted according to actual road conditions. This design can automatically adjust the position of the limit slide column according to the degree of bumps, so that the building components are always kept in a relatively stable state. Whether it is a slight bump or a more severe vibration, it can effectively protect the components and improve the adaptability and reliability of transportation. At the same time, traditional transport racks use complex shock absorption systems, such as hydraulic shock absorbers or air springs. These systems are not only costly, but also difficult to maintain. The design structure of the limit slide column and the arc block is simple, the cost is low, and it also has high reliability. In actual use, even if a fault occurs, it is easy to repair and replace, and will not cause much impact on transportation work.
[0020] Secondly, when the transport frame is not transporting building components, the two limit sliding columns inside the arc block can be fixed by the arc-shaped limit buckle, thereby avoiding the wear caused by the limit sliding columns sliding along the inner wall of the arc block for a long time, thereby improving the service life of the equipment. The installation and disassembly of the arc-shaped limit buckle are designed to be relatively simple, which is convenient for operators to operate quickly when needed.
[0021] 2. Through the setting of the automatic layering component, when the transport rack is assembling building components, after the staff places the building components on the first placement plate, the first placement plate will contact the working-shaped rotating rod at the bottom of the second placement plate through the limit bar, so that the second placement plate will automatically tilt at a certain angle, so that the subsequent building components will contact the second placement plate, and there is a certain interval between the first placement plate and the second placement plate, so that there is a certain gap between the first placement plate and the second placement plate. Compared with the traditional building PC component intelligent transport rack, the traditional transport rack usually needs to manually adjust the angle of the placement plate or use a complex mechanical structure to assist in loading, which is cumbersome and inefficient. With this automatic layering design, the staff only needs to place the building components on the first placement plate to trigger the tilting of the second placement plate, which greatly simplifies the loading process and improves the loading efficiency;
[0022] Secondly, since there is a certain gap between the first placement plate and the second placement plate, the building components will not be directly squeezed together when placed on them, and the size of the gap can be adjusted according to the size and material of different components to ensure that the components will not be damaged due to mutual squeezing during transportation. At the same time, the number of second placement plates can be added appropriately according to the number of building components, which solves the problem of large-scale transportation of building components. At the same time, building components will be tightly stacked together in traditional transport racks, and they are prone to collision and squeezing each other due to bumps, vibrations, etc. during transportation, resulting in wear, deformation and even damage to the surface of the components. This gap design can effectively reduce the contact between components, reduce the risk of damage, and ensure the quality of building components. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they should not be understood as limitations on the present invention.
[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0039] Implementation example Figures 1 to 10As shown, an embodiment of the present invention provides an intelligent transport rack for assembled building PC components, including a transport plate 11, a balancing component for assisting the smooth transportation of building PC components is arranged on the top of the transport plate 11, and an automatic stratification component for automatically arranging building PC components at intervals is arranged above the transport plate 11.
[0040] The balancing assembly includes a positioning column group 21, which is fixedly connected to the top of the transport plate 11. The top of the positioning column group 21 is symmetrically fixedly connected with an arc block 22. The inner walls of the two arc blocks 22 are slidably connected with two limiting sliding columns 23. The outer walls of the two limiting sliding columns 23 are fixedly connected with a buffer plate 24.
[0041] The balancing assembly further includes a fixed rod group 25 , which is fixedly connected to the top of the transport plate 11 , and the top of the fixed rod group 25 is rotatably connected to four arc-shaped limit buckles 26 .
[0042] The automatic stratification component includes a placement rack 31, which is fixedly connected to the top of the buffer plate 24. A square groove 32 is opened inside the placement rack 31. The bottom of the square groove 32 is rotatably connected to a rotating column 33. The outer wall of the rotating column 33 is rotatably connected to a first placement plate 34 and a second placement plate 35.
[0043] The automatic layering component further comprises a limit bar 37 , which is fixedly connected to the top of the first placement plate 34 , and a work-shaped rotating rod 36 is slidably connected inside the limit bar 37 .
[0044] Limiting rings are provided at both ends of the two limiting slides 23, so that the limiting slides 23 can only slide along a fixed path on the inner wall of the arc block 22, and four arc-shaped limiting buckles 26 are clamped on the two ends of the two limiting slides 23 in a group of two, so that the arc-shaped limiting buckles 26 have a limiting effect on the limiting slides 23.
[0045] The first placement plate 34 and the second placement plate 35 are both configured to be L-shaped, and a weight block is provided at the end of the first placement plate 34 and the second placement plate 35 away from the placement frame 31, so that the mass of the end of the first placement plate 34 and the second placement plate 35 away from the placement frame 31 is greater than that of the other end, which is used to maintain the inclination angle of the first placement plate 34 and the second placement plate 35, and the end of the working-shaped rotating rod 36 away from the limit bar 37 is rotatably connected to the inside of the weight block of the first placement plate 34, so that the limit bar 37 will trigger the second placement plate 35 to rotate through the working-shaped rotating rod 36 during the movement.
[0046] Two second placement plates 35 are provided, and the bottoms of the two second placement plates 35 are rotatably connected with a work-shaped rotating rod 36, so that the second placement plates 35 can adjust the top second placement plates 35 in turn through the limit strips 37 and the work-shaped rotating rod 36 when the building components are layered.
[0047] The second placement plates 35 can be appropriately increased according to the number of building components, and the top second placement plate 35 does not need to be provided with a limit bar 37. Instead, all the weight-increasing blocks of the second placement plates 35 are provided with a work-shaped rotating rod 36 inside, and a limit column 38 is provided above the second placement plates 35.
[0048] The automatic layering components are symmetrically arranged inside the placement rack 31.
[0049] Working principle: In the initial state, the end of the working-shaped rotating rod 36 away from the weight-adding block of the second placing plate 35 is located at the bottom of the limiting bar 37, and the end of the second placing plate 35 away from the weight-adding block is in conflict with the limiting column 38. The distance between the two first placing plates 34 is always smaller than the length of the inner diameter of the placing frame 31, and the arc-shaped limiting buckle 26 is in conflict with the limiting sliding column 23.
[0050] When working, the staff first needs to place the building components inside the placement rack 31. The staff only needs to place the building components inside the placement rack 31 in sequence. During this process, because the automatic layering components are symmetrically arranged inside the placement rack 31, the building components will first collide with the two first placement plates 34, and then the building components will drive the two first placement plates 34 to rotate around the placement rack 31 due to their own gravity;
[0051] Then, the end of the first placement plate 34 away from the placement frame 31 drives the limiting bar 37 to rotate, and at this time, the limiting bar 37 contacts the end of the working-shaped rotating rod 36 away from the second placement plate 35 to move, and then the working-shaped rotating rod 36 gradually rotates along the end of the second placement plate 35 away from the placement frame 31, and at the same time, the working-shaped rotating rod 36 will contact the second placement plate 35 to rise away from the placement frame 31. Because the first placement plate 34 and the second placement plate 35 are along the outer wall of the rotating column 33, when the second placement plate 35 rises away from the placement frame 31, the second placement plate 35 will rotate along the outer wall of the rotating column 33, and then the end of the second placement plate 35 away from the working-shaped rotating rod 36 will stop contacting the limiting column 38, and at this time, the distance between the two second placement plates 35 is less than the length of the inner diameter of the placement frame 31;
[0052] When the staff member subsequently continues to place building components into the placement rack 31, the building components will collide with the two second placement plates 35, which is the same as the above-mentioned movement process. Because there are two second placement plates 35, and the bottoms of the two second placement plates 35 are rotatably connected with the work-shaped rotating rods 36, the second placement plates 35 can adjust the top second placement plates 35 in turn through the limit bars 37 and the work-shaped rotating rods 36 when layering the building components, so that when the building components are placed on the second placement plate 35 away from the work-shaped rotating rod 36, the second placement plate 35 will collide with the work-shaped rotating rod 36 of the upper second placement plate 35 through the limit bars 37, so that the upper second placement plate 35 is tilted, so that the distance between the upper two second placement plates 35 is less than the length of the inner diameter of the placement rack 31, thereby achieving the purpose of continuously placing building components;
[0053] Because the first placing plate 34 and the second placing plate 35 are both configured to be L-shaped, and weight blocks are provided at the ends of the first placing plate 34 and the second placing plate 35 away from the placing frame 31, the mass of the end of the second placing plate 35 away from the placing frame 31 is greater than that of the other end, which is used to maintain the inclination angle of the first placing plate 34 and the second placing plate 35, so that when the second placing plate 35 below does not place building components, the spacing between the second placing plates 35 above is greater than the length of the inner diameter of the placing frame 31, so that the second placing plate 35 is hidden inside the square groove 32, avoiding accidental touch when the building components are continuously placed.
[0054] At the same time, there is a certain interval between the first placement plate 34 and the second placement plate 35, so that there is a certain gap between the first placement plate 34 and the second placement plate 35 for the building components. Compared with the traditional building PC component intelligent transport rack, the traditional transport rack usually needs to manually adjust the angle of the placement plate or use a complex mechanical structure to assist in loading, which is cumbersome and inefficient. With this automatic layering design, the staff only needs to place the building component on the first placement plate 34 to trigger the tilt of the second placement plate 35, which greatly simplifies the loading process and improves the loading efficiency. At the same time, since there is a certain gap between the first placement plate 34 and the second placement plate 35, the building components will not be directly squeezed together when placed on them, and the size of the gap can be adjusted according to the size and material of different components to ensure that the components will not be damaged due to mutual squeezing during transportation;
[0055] In addition, since the second placement plates 35 can be appropriately increased according to the number of building components, and the top second placement plate 35 does not need to be provided with a limit bar 37, and the weight-increasing blocks of all the second placement plates 35 are provided with a work-shaped rotating rod 36, the same as the above-mentioned movement process, when the building components are placed on the second placement plate 35 away from the end of the work-shaped rotating rod 36, the second placement plate 35 will contact the work-shaped rotating rod 36 of the upper second placement plate 35 through the limit bar 37, thereby causing the upper second placement plate 35 to tilt, so that the distance between the two upper second placement plates 35 is less than the length of the inner diameter of the placement frame 31, thereby achieving the purpose of continuously placing the building components. Since the number of second placement plates 35 can be appropriately increased according to the number of building components, the problem of large-scale transportation of building components is solved.
[0056] After the loading of the building components is completed, the staff needs to rotate the four arc-shaped limit buckles 26 away from the limit slide column 23 so that the four arc-shaped limit buckles 26 release the restriction on the two limit slide columns 23. At this time, the staff needs to fix the transport plate 11 on the truck to achieve the purpose of transporting the building components. When the truck passes through a bumpy road section, the building components loaded on the truck will shake. Since the placement frame 31 is fixed on the top of the buffer plate 24, the inertia of the shaking of the building components will cause the buffer plate 24 to drive the two limit slide columns 23 to slide along the arc block 22.
[0057] Because both ends of the two limit slides 23 are provided with limit rings, the limit slides 23 can only slide along a fixed path on the inner wall of the arc block 22. At this time, the limit slides 23 slide along the arc block 22 to consume part of the power generated by the building components. The arc block 22 is in an arc shape, so the two limit slides 23 only drive the placement frame 31 and the buffer plate 24 to reciprocate and will not fall. The movement of the two limit slides 23 effectively absorbs and buffers the bump energy, greatly reduces the impact force on the building components, and reduces the risk of collision damage;
[0058] Secondly, the conventional transport rack usually adopts a fixed support structure and cannot be adaptively adjusted according to the actual road conditions. However, this design can automatically adjust the position of the limit slide column 23 according to the degree of bumps, so that the building components are always kept in a relatively stable state. Whether it is a slight bump or a more severe vibration, it can effectively protect the components and improve the adaptability and reliability of transportation. At the same time, the conventional transport rack adopts a complex shock absorption system, such as hydraulic shock absorbers or air springs, which are not only costly but also difficult to maintain. The limit slide column 23 and the arc block 22 have a simple design structure, low cost, and high reliability. In actual use, even if a fault occurs, it is easy to repair and replace, and will not cause much impact on the transportation work.
[0059] After the transportation work is completed, the staff can rotate the four arc-shaped limit buckles 26 towards the limit slide 23, so that the four arc-shaped limit buckles 26 can limit the position of the two limit slides 23 again, thereby avoiding the wear caused by the limit slide 23 sliding along the inner wall of the arc block 22 for a long time, thereby improving the service life of the equipment. The installation and disassembly design of the arc-shaped limit buckles 26 is relatively simple, which is convenient for operators to operate quickly when needed.
