Description

Technical Field

[0001] This utility model relates to the technical field of installation devices for the exterior walls of high-rise buildings, and specifically to a suspended platform. Background Technology

[0002] In the industrial and civil building sector, cold storage tanks are mostly cylindrical with a conical top. High-altitude operations such as the construction of the insulation layer, anti-corrosion treatment, and maintenance of the outer wall often rely on electric lifting baskets.

[0003] Currently, the standard structure commonly used for suspended platforms for aerial work is as follows: two parallel and independently installed suspension mechanisms are installed above the building. The platform is suspended from these two mechanisms via a wire rope system. While this dual-suspension design provides stable support, it occupies a large area of ​​the building's roof. Especially in the relatively compact space of tank roof areas, the arrangement of the two suspension mechanisms and their counterweights is often severely constrained by existing tank roof equipment (such as manholes, pipe connections, safety valve bases, etc.), making the choice of installation location very limited, and sometimes even making it difficult to find sufficient and suitable installation space.

[0004] In addition, in order to meet the needs of circumferential construction around the tank, the existing suspension mechanism needs to rotate around the center of the tank top. However, the heavy suspension mechanism and its counterweight need to be moved as a whole, which is not only time-consuming and labor-intensive and affects efficiency, but also poses a high safety risk when operating on the narrow tank top.

[0005] For the unique geometry of a conical tank top, existing parallel double-suspension basket systems have significant limitations: on the one hand, the effective flat area of ​​the tank top is smaller, exacerbating space constraints; on the other hand, performing rotational movement of a large suspension mechanism on a non-planar conical top further increases complexity and risk.

[0006] Therefore, there is an urgent need for a new type of suspended platform that occupies little space, is easy and efficient to rotate, and is adapted to the special structure and construction requirements of the conical top of the cold storage tank, in order to solve the problems of existing equipment. Utility Model Content

[0007] The purpose of this utility model is to provide a suspended platform to solve the problems in the background art.

[0008] To achieve the above objectives, this application provides a suspended platform, comprising: A central column, the bottom end of which is fixedly connected to the top center of the cold storage tank, and the top end extending vertically; a rotating mechanism, including a rotating frame, a driver, and rollers, the first end of which is rotatably connected to the central column, and the other end extending radially along the cold storage tank; the rollers are located at the bottom of the rotating frame; the driver is fixedly located on the rotating frame; the driver is used to drive the rollers to rotate, so as to drive the rotating frame to perform circular motion around the axis of the cold storage tank. Two sets of booms, with the first ends of the two sets of booms spaced apart on the top surface of the rotating frame and fixedly connected to the rotating frame, and the other ends of the booms extending horizontally to the outside of the cold storage tank, and each of the other ends is provided with a certain pulley; A suspended platform is located outside the cold storage tank. Two winches are spaced apart on the suspended platform. The two winches are correspondingly connected to the fixed pulleys on the two booms. A wire rope passes over one of the fixed pulleys and is connected to the corresponding winch.

[0009] As a preferred technical solution, the rotating frame includes a main boom and a roller frame. One end of the main boom is rotatably connected to the central column, and the other end is fixedly connected to the roller frame. The rollers are installed at the bottom of the roller frame, and the first end of the boom is fixedly connected to the roller frame.

[0010] As a preferred technical solution, the top surface of the roller frame is gradually inclined upward from the side closer to the main arm to the side farther away from the main arm.

[0011] As a preferred technical solution, the suspended platform further includes: a plurality of first reinforcing ribs, which are spaced apart on the bottom outer periphery of the central column, and one end of each first reinforcing rib is fixedly connected to the outer periphery of the central column, and the other end is fixedly connected to the cold storage tank.

[0012] As a preferred technical solution, the suspended platform further includes: diagonal bracing rods, with multiple diagonal bracing rods spaced apart on the outer periphery of the central column, and one end of each diagonal bracing rod being fixedly connected to the outer periphery of the central column, and the other end being fixedly connected to the cold storage tank.

[0013] As a preferred technical solution, the suspended platform further includes: The first support rod has a first end fixedly connected to the rotating frame and disposed away from the central column, and the other end extends upward in the vertical direction; Two sets of first connecting members, with the two ends of the two sets of first connecting members respectively fixedly connected to the other end of the first support rod and the end of the boom away from the rotating frame; The second connector has its two ends fixedly connected to the other end of the first support rod and the first end of the rotating frame, respectively.

[0014] As a preferred technical solution, the first connector and the second connector are steel pipes / wire ropes.

[0015] As a preferred technical solution, the suspended platform further includes: a connecting sleeve, which is sleeved on the outer peripheral wall of the central column, and the rotating frame is rotatably connected to the connecting sleeve.

[0016] As a preferred technical solution, the suspended platform further includes a second reinforcing rib plate, the two ends of which are fixedly connected to the outer peripheral wall of the connecting sleeve and the central column, respectively.

[0017] As a preferred technical solution, the connection between the central column and the cold storage tank, and the connection between the boom and the rotating frame are both welded.

[0018] The suspended platform provided by the above technical solution has the following advantages compared with the prior art: By setting a central column at the center of the top surface of the cold storage tank, a rotating frame rotatably connected to the central column, a boom fixedly connected to the rotating frame, and a wire rope connecting the boom to a winch on the suspended platform, the rotating frame, driven by a driver, rotates in a circular motion around the axis of the central column. This causes the boom, suspended platform, and wire rope to move in a synchronized circular motion, facilitating adjustments to the position of the suspended platform according to construction needs. Furthermore, the central column and rotating frame ensure the strength and stability of the suspension structure, eliminating the need for additional counterweights that would occupy tank top area. This results in a smaller overall footprint, simpler and more efficient rotation operation, and suitability for the unique conical top structure and construction requirements of cold storage tanks.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] Please see Figure 1-3This application provides a suspended platform, comprising: a central column 100, the bottom end of which is fixedly connected to the top center of the cold storage tank, and the top end extending vertically; and a rotating mechanism 200, comprising: a rotating frame 201, a driver (not shown in the drawings), and rollers 202. The first end of the rotating frame 201 is rotatably connected to the central column 100, and the other end extends radially along the cold storage tank. The rollers 202 are disposed at the bottom of the rotating frame 201. The driver is fixedly disposed on the rotating frame 201 and is used to drive the rollers 202 to rotate, thereby rotating the rotating frame 201 to the cold storage tank. The tank moves in a circular motion around its axis; two sets of booms 300, the first ends of which are spaced apart on the top surface of the rotating frame 201 and fixedly connected to the rotating frame 201, and the other ends of which extend horizontally to the outside of the cold storage tank, and the other end of which is provided with a fixed pulley 301; a suspended platform 400, which is located outside the cold storage tank, and two winches are spaced apart on the suspended platform 400, and the two winches are correspondingly arranged with the fixed pulleys 301 on the two booms 300; a wire rope 500 passes over one of the fixed pulleys 301 and is connected to the corresponding winch.

[0028] In this embodiment, a central column 100 is first fixed vertically at the center of the top surface of the cold storage tank. Then, a rotating frame 201 is rotatably connected to the central column 100, allowing the rotating frame 201 to rotate around the axis of the central column 100 under the drive of pulleys. A boom 300 is connected to the end of the rotating frame 201 furthest from the central column 100. Two booms 300 are spaced apart, with the distance between the ends of the two booms 300 furthest from the rotating frame 201 being the same as the distance between the two cigarette-making machines on the suspended platform 400. This ensures that after the wire rope 500 passes over the fixed pulley 301 at the end of the boom 300 and connects to a winch, the wire rope 500 remains vertical, and the center of force on the suspended platform 400 is on the same straight line as the suspension point, minimizing horizontal sway. When the suspended platform 400 needs to be moved to the construction position, simply activate the drive to rotate the rollers 202, causing the boom 300 to rotate around the axis of the central column 100 on the top of the tank. Simultaneously, this moves the suspended platform 400 around the outer circumference of the tank, allowing for rapid movement to the construction position. Position adjustment is simple and efficient, and it is well-suited to the special shape and construction requirements of the cold storage tank. Furthermore, the central column 100 and the rotating frame 201 form a rotating structure, eliminating the need for additional counterweights to ensure structural rigidity, reducing the space occupied by the device, and providing more construction space for other operations.

[0029] In some embodiments, the rotating frame 201 includes a main arm 2011 and a roller frame 2012. One end of the main arm 2011 is rotatably connected to the central column 100, and the other end is fixedly connected to the roller frame 2012. The rollers 202 are installed at the bottom of the roller frame 2012, and the first end of the boom 300 is fixedly connected to the roller frame 2012.

[0030] In this embodiment, the roller frame 2012 connects the main boom 2011, rollers 202, and boom 300, forming an integrated load-bearing node. The load generated by the boom 300 during operation can be transferred to the main boom 2011 through the roller frame 2012, and then from the main boom 2011 to the central column 100, avoiding excessive stress at a single point that could lead to deformation. The rollers 202 are installed at the bottom of the roller frame 2012, which can distribute part of the weight of the rotating frame 201 to the top of the tank, reducing the load-bearing pressure on the central column 100 and reducing the frictional resistance when the main boom 2011 rotates. If the boom 300 is directly connected to the main boom 2011, the main boom 2011 may have an excessively long lever arm, resulting in an excessive bending moment. However, by using the roller frame 2012 as an intermediate carrier, the lever arm distance between the boom 300 and the main boom 2011 can be shortened, optimizing the load-bearing structure. Preferably, this application features a track on the top of the tank, with rollers 202 positioned within the track. The rollers 202 assist the entire rotating frame 201 in horizontal movement, coordinating with the rotation of the main boom 2011 to further expand the working range. Furthermore, the rolling friction of the rollers 202 is far less than the sliding friction, reducing the resistance during the rotation of the main boom 2011, lowering the load on the drive unit, and extending the equipment's lifespan.

[0031] In some embodiments, the top surface of the roller frame 2012 is gradually inclined upwards from the side closer to the main boom 2011 to the side farther away from the main boom 2011. This inclined top surface of the roller frame 2012 causes the boom 300, which is fixedly connected to it, to also tilt, i.e., the boom 300 forms a certain angle of elevation with the horizontal plane. This allows the weight of the load being lifted or suspended to have a component force along the axial direction of the boom 300, making the boom 300 primarily bear axial tension. Compared to a horizontal or downward tilted state, this force distribution method is more in line with the mechanical properties of metal structures; that is, the tensile strength of the boom 300 is better than its bending strength, which can significantly reduce the bending moment and deflection of the boom 300, reducing the risk of deformation or breakage. Moreover, the upward tilt of the boom 300 makes the load suspension point higher than the boom 300 connection point, forming an "upward pull" force distribution, making it easier for the load to remain stable during lifting or movement, and less prone to displacement due to wind, inertia, etc.

[0032] The connection between the bottom of the central column 100 and the cold storage tank is a critical node for load transfer, needing to withstand the weight of the central column 100 itself, the vertical pressure from the upper structure, and the lateral forces generated during operation. If only a direct connection is used, excessive local stress can easily lead to deformation and cracking at the connection point. Therefore, in some embodiments, the suspended platform further includes multiple first reinforcing ribs 600, which are spaced apart on the outer periphery of the bottom of the central column 100. One end of each first reinforcing rib 600 is fixedly connected to the outer peripheral wall of the central column 100, and the other end is fixedly connected to the cold storage tank. The first reinforcing ribs 600 are fixed to the outer peripheral wall of the central column 100 and the cold storage tank respectively through surface contact, effectively adding a rigid transition structure between the connection points. The thickness and rigidity of the first reinforcing ribs 600 can disperse concentrated stress, transferring the force originally concentrated at the connection edge to a larger area, preventing local material fatigue damage due to long-term high stress.

[0033] In some embodiments, the suspended platform further includes: diagonal bracing rods 700, multiple diagonal bracing rods 700 are spaced apart on the outer periphery of the central column 100, and one end of each diagonal bracing rod 700 is fixedly connected to the outer periphery of the central column 100, and the other end is fixedly connected to the cold storage tank.

[0034] In this embodiment, the diagonal braces 700 rigidly connect the central column 100 and the cold storage tank into a single unit, rather than independent components, significantly improving the overall rigidity of the equipment. This collaborative structure effectively suppresses vibrations during operation and swaying caused by the external environment. The stable structure avoids problems such as pipe loosening and seal failure caused by swaying of the medium inside the cold storage tank. Furthermore, multiple diagonal braces 700 form multiple triangular structures with the central column 100 and the cold storage tank, effectively resisting lateral forces from different directions. When the central column 100 is subjected to lateral thrust or tension, the diagonal braces 700 can transmit the force along their own axial direction to the cold storage tank, preventing the central column 100 from bending, tilting, or even tipping over due to excessive force on one side. The multiple diagonal braces 700 evenly arranged around the circumference of the central column 100 can cover all directions of force application. Regardless of the angle from which the external force comes, the load can be distributed through the corresponding diagonal braces 700, forming all-round protection.

[0035] In some embodiments, the suspended platform further includes: a first support rod 800, one end of which is fixedly connected to the rotating frame 201 and disposed away from the central column 100, and the other end extending vertically upward; two sets of first connecting members 900, the two ends of which are respectively fixedly connected to the other end of the first support rod 800 and the end of the boom 300 away from the rotating frame 201; and a second connecting member 1000, the two ends of which are respectively fixedly connected to the other end of the first support rod 800 and the first end of the rotating frame 201. Stable triangular reinforcement structures are formed between the first support rod 800, the first connecting member 900, and the boom 300, and between the second connecting member 1000, the first support rod 800, and the main boom 2011, further improving the overall structural rigidity and ensuring structural stability.

[0036] In some embodiments, the first connector 900 and the second connector 1000 are steel pipes / wire ropes 500. On one hand, steel pipes have high compressive, bending, and shear strength, and can withstand large axial and lateral forces. In a triangular structure, the steel pipe can act as a rigid support, resisting the instantaneous impact force generated by equipment shaking and preventing structural failure due to deformation. On the other hand, the wire rope 500 has extremely high tensile strength and is flexible, adapting flexibly to minor structural deformations. In a triangular structure, the wire rope 500 mainly acts as a flexible tension member, capable of withstanding large axial tensile forces. When the structure is subjected to dynamic loads, the wire rope 500 can absorb some energy through its own elastic deformation, reducing the impact on the first support rod 800.

[0037] In some embodiments, the suspended platform further includes a connecting sleeve 1100, which is sleeved on the outer peripheral wall of the central column 100, and the rotating frame 201 is rotatably connected to the connecting sleeve 1100. The connecting sleeve 1100 serves as a transitional rotating carrier between the central column 100 and the rotating frame 201. The inner circumference of the connecting sleeve 1100 can precisely fit with the outer circumference of the central column 100, while the outer circumference forms a suitable rotating pair with the connection part of the rotating frame 201, ensuring that the rotating frame 201 can rotate smoothly around the central column 100 and reducing jamming or frictional resistance. Simultaneously, the connecting sleeve 1100 prevents the outer peripheral wall of the central column 100 from directly bearing rotational wear, extending the service life of the central column 100.

[0038] The connecting sleeve 1100 is fitted onto the outer periphery of the central column 100. Although initial fixation is achieved through this fitting, under axial or radial forces, the contact area between the two may experience relative sliding, loosening, or slight deformation due to gaps or excessive local stress. Therefore, in some embodiments, the suspended platform further includes a second reinforcing rib (not shown in the drawings), with both ends of the second reinforcing rib fixedly connected to the outer peripheral wall of the connecting sleeve 1100 and the central column 100, respectively. The second reinforcing rib, the connecting sleeve 1100, and the central column 100 form a triangular stable structure, rigidly locking the connecting sleeve 1100 and the central column 100, preventing relative displacement along the circumferential or axial direction, and ensuring the integrity of the connection. When the rotating frame 201 drives the connecting sleeve 1100 to rotate, the second reinforcing rib can counteract the frictional torque between the connecting sleeve 1100 and the central column 100, preventing the sleeve from shifting due to long-term stress.

[0039] In some embodiments, the connection between the central column 100 and the cold storage tank, and between the boom 300 and the rotating frame 201, are welded. Firstly, the cold storage tank is heavy and may bear internal pressure; welding ensures a rigid connection between the central column 100 and the cold storage tank, resisting the weight of the tank and external environmental loads, preventing loosening or breakage at the connection point. Secondly, the boom 300 needs to bear the lifting load and generates dynamic stress when rotating with the rotating frame 201; welding can transmit significant tensile, bending, and torque forces, ensuring that the boom 300 does not undergo relative displacement during operation, thus guaranteeing lifting safety.

[0040] In summary, the suspended platform provided in this embodiment occupies little space, is easy and efficient to rotate, and is suitable for the special structure of the conical top of the cold storage tank and construction requirements, thus solving the problems existing in the current equipment.

[0041] This specification discloses the present application with reference to the accompanying drawings and also enables those skilled in the art to implement the application, including making and using any device or system, employing suitable materials, and using any combination of methods. The scope of this application is defined by the claimed technical solution and includes other instances that would occur to those skilled in the art.
