Description

Technical Field

[0001] This invention relates to the field of composite duct installation technology, and in particular to a high-altitude composite duct transportation mobile platform. Background Technology

[0002] With the increasing number of public construction projects, most of which use steel structures, the roof designs are becoming more and more complex, and the space inside the trusses is narrow, making it impossible to install them using the traditional truck crane method. It is imperative to find a new hoisting method to assist in construction.

[0003] When installing high-altitude composite ducts, electric hoists are used to transport the composite ducts to a mobile platform, where workers then adjust, fix, and install the ducts. However, existing mobile platforms have simple structures, limited functionality, low safety, and cannot be adjusted in height, which increases the difficulty of operation for workers and reduces construction efficiency. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a high-altitude composite duct transportation mobile platform, which can effectively solve the problems existing in the prior art.

[0005] The technical solution of this invention is:

[0006] According to one aspect of the present invention, the device includes: a mobile platform, a lifting device, and an auxiliary device. A fixed plate is fixedly provided at the upper end of the mobile platform. The auxiliary device includes a base plate, a platform plate, and first rollers. A plurality of first rollers are arranged at intervals on the base plate, and a plurality of second slots are provided on the platform plate to cooperate with the first rollers.

[0007] The base plate is fixedly connected to the fixed plate. A platform plate is provided on the upper end of the base plate and is equipped with a lifting device for driving the platform plate to rise and fall. Under the drive of the lifting device, the upper surface of the platform plate switches between being higher than the first roller and lower than the first roller. A limit device is slidably provided on the upper end of the platform plate and a first protruding plate is fixed on one end of the base plate.

[0008] The auxiliary device also includes a first fixed shaft and a first limiting block. Multiple first fixed shafts are arranged in a horizontal array inside the base plate, and the first fixed shafts pass through both ends of the base plate. A first limiting block is provided at both ends of the first fixed shaft, and multiple first rollers are arranged through the first fixed shaft.

[0009] The limiting device includes a limiting plate, a slider, and a second roller. The platform plate has grooves on both sides, and the limiting plate has sliders at both ends, with the sliders slidably connected to the grooves. Multiple second rollers are arranged at intervals on the side of the limiting plate, and a second protrusion is fixed at one end of the limiting plate.

[0010] The mobile platform is equipped with multiple limiting components on its front and rear sides that are fixed to the horse track E.

[0011] In the above technical solution, the purpose of this setting is that when the staff connects each composite air duct, they can slide the composite air duct on the platform plate to move it to the corresponding position. Then, driven by the lifting device, the platform plate is raised to lift the composite air duct to the corresponding height, so that it can be connected with the previous composite air duct. This saves time and effort, reduces the workload of the staff, and improves work efficiency.

[0012] If the composite duct needs to be aligned after the platform is raised, the sliding limit plate can be used to assist the staff in aligning the composite duct, saving time and effort.

[0013] This improves the stability of the mobile platform fixed on the walkway E, preventing the platform from swaying from side to side and enhancing the safety of workers.

[0014] In some embodiments, the auxiliary device further includes a first fixed shaft and a first limiting block. Multiple first fixed shafts are arranged in a horizontal array inside the base plate, and the first fixed shafts pass through both ends of the base plate. A first limiting block is provided at both ends of the first fixed shaft, and multiple first rollers are arranged through the first fixed shaft.

[0015] In the above technical solution, the purpose of this setting is to enable the operator to slide the composite air duct on the platform plate through the first roller, thereby moving the composite air duct to the corresponding position.

[0016] In some embodiments, the upper end of the platform plate is provided with a plurality of anti-slip protrusions evenly distributed.

[0017] In the above technical solution, the purpose of this setting is that when the lifting device is raised, the anti-slip protrusions on the platform plate enhance the friction between the composite air duct and the platform plate, which prevents the composite air duct from moving easily, making it convenient for workers to install. In addition, the anti-slip protrusions also make the workers stand more stably, improving the safety of the operation.

[0018] In some embodiments, the lifting device includes a scissor jack, a housing, and a motor. The housing is fixed to the bottom of the fixed plate. The scissor jack is installed inside the housing. The scissor jack includes a fixed base, a scissor-type multi-link mechanism, a screw, and a lifting seat. The fixed base is fixedly connected to the housing. One end of the screw is equipped with a motor that rotates it. The lifting seat is fixedly provided with a slide rod, and one end of the slide rod passes through the fixed plate and the bottom plate and is fixedly connected to the platform plate.

[0019] In the above technical solution, the purpose of this setting is that when the staff connects the composite air ducts, there is a height difference between the previous composite air duct and the next composite air duct. The lifting device can lift the composite air duct to the corresponding position and align it with the previous composite air duct, which facilitates the installation by the staff.

[0020] In some embodiments, the limiting plate is provided with a plurality of second fixed shafts arranged in a horizontal array inside, and the second fixed shafts pass through the upper and lower ends of the limiting plate. A third limiting block is provided at both ends of the second fixed shaft. A plurality of second rollers are provided through the second fixed shaft, and a second limiting block is provided at both ends of the second rollers. A second protruding plate is fixed at one end of the limiting plate.

[0021] In the above technical solution, the purpose of this setting is that after the composite air duct is aligned twice, the staff can push the composite air duct to assemble it.

[0022] According to another aspect of the invention, the method includes the following steps:

[0023] S1. Push the mobile platform so that it moves along the walkway toward the composite duct to be installed.

[0024] S2. After pushing the mobile platform to the destination, use a chain to lock the limiting component to the walkway;

[0025] S3. Use an electric hoist to place the composite duct to be installed on the platform plate and install the first section of the composite duct.

[0026] S4. Move the mobile platform to perform initial alignment of the second section of the composite duct. At this time, the platform plate is in a low position, that is, the first roller is higher than the platform plate.

[0027] S5. Push the composite duct so that the lower end face of the next section of the composite duct comes into contact with multiple first rollers.

[0028] S6. After initial alignment, start the lifting device to raise the platform plate until the upper end face of the first convex plate contacts the lower end face of the previous composite air duct, then turn off the lifting device.

[0029] S7. The sliding limit plate is used to accurately position the next section of the composite duct. The next section of the composite duct contacts the second roller, so that one side of the second convex plate abuts against one side of the previous section of the composite duct. After aligning with the previous section of the composite duct, the next section of the composite duct is pushed to install it.

[0030] In some embodiments, step S7 specifically includes the following steps: After precise positioning, there is a gap between the previous section of the composite duct and the next section of the composite duct. A tool can be used to tap the next section of the composite duct to align them.

[0031] By adopting the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows:

[0032] When connecting each composite duct, the staff can slide the composite duct on the platform plate to move it to the corresponding position. Then, driven by the lifting device, the platform plate is raised, lifting the composite duct to the corresponding height, so that it can be connected to the previous composite duct. This saves time and effort, reduces the workload of the staff, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 8 As shown, this solution provides a high-altitude composite duct transportation mobile platform, including: a mobile platform 1, a lifting device 2, and an auxiliary device 3. The mobile platform 1 is fixedly provided with a fixed plate 12 at its upper end. The auxiliary device 3 includes a base plate 31, a platform plate 36, and first rollers 34. The base plate 31 is provided with a plurality of first rollers 34 arranged at intervals. The platform plate 36 is provided with a plurality of second slots 361 that cooperate with the first rollers 34. The base plate 31 is fixedly connected to the fixed plate 12. The platform plate 36 is provided on the upper end of the base plate 31 and is equipped with the lifting device 2 for driving the platform plate 36 to rise and fall. Under the drive of the lifting device 2, the upper surface of the platform plate 36 switches between being higher than the first rollers 34 and lower than the first rollers 34. The upper end of the platform plate 36 is slidably provided with a limit device 4, and a switch 5 is provided on one side of the platform plate 36. A first protruding plate 300 is fixedly provided at one end of the base plate 31.

[0046] In the above technical solution, the purpose of this setting is that when the staff connects each composite air duct B, they can slide the composite air duct B on the platform plate 36 to move the composite air duct B to the corresponding position. Then, driven by the lifting device 2, the platform plate 36 is raised, lifting the composite air duct B to the corresponding height. The first convex plate 300 can abut against the bottom of the previous composite air duct B, so that it can be connected with the previous composite air duct B. This saves time and effort, reduces the workload of the staff, and improves work efficiency.

[0047] Please see Figure 1 and Figure 2 The support frame of the mobile platform 1 consists of four uprights, short side crossbars, long side crossbars, a middle upright, and diagonal braces. For ease of installation and disassembly, all connections are made by bolts. In other embodiments, other fixing connection methods, such as welding, can also be used.

[0048] The central uprights and diagonal braces are reinforcements, which are necessary when the area of ​​the mobile platform 1 is large, in order to ensure the strength of the mobile platform 1.

[0049] The bottom of the four uprights is equipped with pulleys to transport the composite air duct B. The pulleys are equipped with pulley brakes to control the movement and fix the platform, thereby ensuring the safety of the staff.

[0050] Multiple handles 6 are symmetrically arranged on both sides of the fixing plate 12, which serve as gripping points in extremely dangerous situations.

[0051] Please see Figure 6 , Figure 7 and Figure 8 In some embodiments, the auxiliary device 3 further includes a first fixed shaft 32 and a first limiting block 33. Multiple first fixed shafts 32 are arranged in a horizontal array inside the base plate 31. Screw holes 311 are provided at the four corners of the base plate 31 to facilitate assembly and disassembly by workers. The first fixed shaft 32 passes through both ends of the base plate 31. A first limiting block 33 is provided at both ends of the first fixed shaft 32. Multiple first rollers 34 are arranged through the first fixed shaft 32. The base plate 31 is also arranged in an array with first slots 312 through which the first rollers 34 can pass. Second limiting blocks 35 are provided on both sides of the first rollers 35.

[0052] The limiting device 4 includes a limiting plate 41, a slider 42, and a second roller 45. The platform plate 36 is provided with sliding grooves 362 on both sides. The limiting plate 41 is provided with sliders 42 at both ends, and the sliders 42 are slidably connected to the sliding grooves 362. Multiple second rollers 45 are arranged at intervals on the side of the limiting plate 41.

[0053] The limiting plate 41 has a plurality of second fixed shafts 43 arranged in a horizontal array inside, and the second fixed shafts 43 pass through the upper and lower ends of the limiting plate 41. A third limiting block 44 is provided at both ends of the second fixed shafts 43. A plurality of second rollers 45 are provided through the second fixed shafts 43, and a second limiting block 35 is provided at both ends of the second rollers 45. A second protruding plate 400 is fixed at one end of the limiting plate 41.

[0054] In the above technical solution, the purpose of this setting is: the first roller 34 allows the operator to slide the composite air duct B on the platform plate 36, thereby moving the composite air duct B to the corresponding position. If the platform plate 36 is raised and further alignment of the composite air duct B is required, the limiting plate 41 can be slid to assist the operator in aligning the composite air duct B. The second convex plate 400 can be aligned with the previous section of the composite air duct B, saving time and effort.

[0055] Please see Figure 1 In some embodiments, the mobile platform 1 is provided with a plurality of limiting members 11 fixed to the horse track E on the front and rear sides, and anti-tipping chains are used to fix the limiting members 11 to the horse track E.

[0056] In the above technical solution, the purpose of this setting is to improve the stability of the mobile platform 1 fixed on the walkway E, so that the mobile platform 1 will not sway from side to side, thereby improving the safety of the workers.

[0057] Please see Figure 6 In some embodiments, the upper end of the platform plate 36 is provided with a plurality of anti-slip protrusions 37, which are semi-circular in shape. In other embodiments, they can also be any other shape with anti-slip effect.

[0058] In the above technical solution, the purpose of this setting is that when the lifting device 2 is raised, the anti-slip protrusions 37 on the platform plate 36 enhance the friction between the composite air duct B and the platform plate 36, so that the composite air duct B will not move easily, making it convenient for workers to install. In addition, the setting of the anti-slip protrusions 37 can also make the workers stand more stably, improving the safety of the operation.

[0059] Please see Figure 3 , Figure 4 and Figure 5In some embodiments, the lifting device 2 includes a scissor jack, a housing 21, and a motor 23. The housing 21 is fixed to the bottom of the fixed plate 12. The scissor jack is assembled inside the housing 21. The scissor jack includes a fixed base 26, a scissor-type multi-link mechanism, a screw 25, and a lifting seat 261. The fixed base 26 is fixedly connected to the housing 21. One end of the screw 25 is equipped with a motor 23 to rotate it. The lifting seat 261 is fixedly provided with a sliding rod 29, and one end of the sliding rod 29 passes through the fixed plate 12 and the bottom plate 31 and is fixedly connected to the platform plate 36. A support rod 22 is fixedly provided at the bottom of the motor 23. In this embodiment, the scissor jack is composed of multiple connecting rods 27 that are intersected and connected. The intersection of the connecting rods 27 is connected by a shaft cylinder 210. Multiple scissor jacks are provided to enhance the stability of the platform plate 36. The scissor jack is an existing technology and will not be described in detail here.

[0060] In the above technical solution, the purpose of this setting is that when the staff connects the composite air ducts, there is a height difference between the previous composite air duct section B and the next composite air duct section B. The lifting device 2 can lift the composite air duct B to the corresponding position and align it with the previous composite air duct section B, which facilitates the installation by the staff.

[0061] According to another aspect of the invention, the method includes the following steps:

[0062] S1. Push the mobile platform 1 so that it moves along the walkway E toward the composite duct B to be installed.

[0063] S2. After pushing the mobile platform 1 to the destination, use a chain to lock the limiting component 11 to the horse track E;

[0064] S3. Use an electric hoist to place the composite duct B to be installed on platform plate 36 and install the first section of composite duct B.

[0065] S4. Move the mobile platform 1 to perform preliminary alignment of the second composite duct B. At this time, the platform plate 36 is in a low position, that is, the first roller 34 is higher than the platform plate 36.

[0066] S5. Push the composite duct B, and the lower end face of the next section of composite duct B will come into contact with multiple first rollers.

[0067] S6. After initial alignment, start the lifting device 2 to raise the platform plate 36 until the upper end face of the first convex plate 300 contacts the lower end face of the previous composite air duct B, and then turn off the lifting device 2.

[0068] S7. The sliding limit plate 41 accurately positions the next section of composite duct B. The next section of composite duct B contacts the second roller 45, so that one side of the second convex plate 400 abuts against one side of the previous section of composite duct B. After aligning with the previous section of composite duct B, the next section of composite duct B is pushed for installation.

[0069] In some embodiments, step S7 specifically includes the following steps: After precise positioning, there is a gap between the previous section of composite duct B and the next section of composite duct B. A tool can be used to tap the next section of composite duct B to align them.

[0070] Please see Figure 9 The diagram shows the orientation of the composite duct B, truss D, and walkway E. The composite duct B is also fixed to the fixing plate 12 by steel wire rope C to prevent the composite duct B from falling from a height.

[0071] Working principle: The operator moves the mobile platform to the position where the composite duct B needs to be assembled. Anti-tipping chains are used to secure the limiting components and the walkway E. The device is then powered on. The operator stands on platform plate 36. Composite duct B is transported to platform plate 36 via an electric hoist. The operator slides composite duct B for alignment. Composite duct B slides on the upper end of the first roller 34. After initial alignment, the operator presses switch 5, which starts motor 23. Motor 23 drives the scissor jack, and the lifting seat 261 raises the sliding rod 29. The sliding rod 29 raises the platform plate 36. Once the platform reaches the corresponding position, the lifting device 2 is turned off. Platform plate 36 stops rising, and staff perform precise alignment. Platform plate 36 detaches from base plate 31. Anti-slip protrusions 37 on platform plate 36 enhance the friction between the composite duct and platform plate 36. When precise alignment of composite duct B is required, sliding limit plate 41 is slidable. Limit plate 41 slides within slide groove 362 via slider 42, allowing composite duct B to fit against the limit plate. After the front and rear positions of composite duct B are aligned, the duct B is then slid left and right for further alignment. The second roller 45 rolls. After precise positioning, there is a gap between the previous and subsequent composite duct sections B. Tools can be used to tap the subsequent composite duct section B for alignment.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
