Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a lifting hanger and a construction operation platform having the same. Background Technology

[0002] The scaffolding system is suspended below the steel platform and can rise with the platform as a whole. During operation, the scaffolding is arranged parallel to one side of the construction wall, providing a working surface for workers to tie rebar, install embedded parts, erect formwork, and pour concrete. Taking the nuclear island platform as an example during integrated platform installation (see...), Figure 1 To prevent the initial installation position of the fulcrum from interfering with the construction of surrounding factory buildings due to an excessively low initial installation position, the initial installation position of the fulcrum was raised. However, this also introduced a problem: the initial position of the lowest working surface of the bracket was higher than the structural layer under construction. Therefore, it was necessary to increase the number of bracket layers to lower the working surface height, resulting in increased bracket weight and increased installation difficulty. Furthermore, after the integrated platform was lifted, taking the nuclear island platform as an example (see...), Figure 2 The top working surface of the scaffolding, serving as the material loading layer, could efficiently transport materials and facilitate the construction of structures on both sides. However, the vertical position of the scaffolding layer is often higher than the structural layer under construction, hindering efficient material transport and thus reducing construction efficiency. Furthermore, in some operating conditions, taking the nuclear island platform as an example (see...),... Figure 3 The construction site is divided into multiple sections on the construction plane. Due to factors such as local penetrations, gates, and personnel organization, the construction progress of some sections is slower than that of others. When the other sections have been completed, in order to provide the working surface for the scaffolding layer of the slower-progressing sections, the platform lifting time will be delayed, which directly slows down the construction progress of the other sections. If the platform is lifted, the scaffolding layer will be higher than the structure of the slower-progressing sections. The only way to catch up is to increase the number of workers. Otherwise, the progress of these sections will become slower and slower, thus affecting the overall construction efficiency.

[0003] Therefore, it is necessary to develop a lifting hanger and a construction operation platform with it, which effectively solves the above-mentioned technical problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a lifting rack and a construction platform thereon, aiming to solve the problems of existing racks having multiple layers, heavy weight, mismatch between the rack's loading surface and the structural construction layer, and inability to lift in sections, which limits the overall progress.

[0005] The present invention solves the above-mentioned technical problems mainly through the following technical solutions: A lifting rack is provided, including a rack body and two sets of vertical lifting devices. The rack body has multiple functional areas distributed vertically inside. The two sets of vertical lifting devices are respectively connected to the two ends of the top of the rack body to drive the rack body to rise and fall.

[0006] Furthermore, the main body of the hanging rack is provided with an extended working platform that can be flipped up and down on the side wall of each functional area on opposite sides.

[0007] Furthermore, the vertical lifting device includes a hoisting device, the lifting part of which is connected to the corresponding top end of the main body of the hanging frame.

[0008] Furthermore, each functional area within the main body of the hanging rack is provided with a climbing structure, which is either a ladder installed on the inner wall of the main body of the hanging rack or a step ladder installed inside the main body of the hanging rack.

[0009] Furthermore, the main body of the hanger is equipped with a fall prevention device, which includes two telescopic rods. The two telescopic rods are vertically spaced at both ends of the top of the main body of the hanger, and the upper ends of the telescopic rods are respectively provided with limit blocks.

[0010] Furthermore, the main body of the hanging frame is provided with a heightening support frame extending downward to its lower part. The lower ends of the heightening support frame are respectively equipped with telescopic devices, and the telescopic ends of the telescopic devices are each equipped with rotatable support rollers.

[0011] Furthermore, the heightening support frame is slidably mounted in the main body of the hanging frame, and the top of the hanging frame main body is provided with a hoisting mechanism connected to the top of the heightening support frame. The hoisting mechanism is used to drive the heightening support frame to rise and fall relative to the hanging frame main body.

[0012] Furthermore, the heightening support frame is installed at both ends of the main body of the hanging bracket.

[0013] Furthermore, guardrails are provided on both sides of the top of the main body of the hanging bracket.

[0014] The beneficial effects of the lifting bracket of the present invention are as follows: The height of the bracket can be flexibly adjusted to ensure that each functional area can be raised and lowered to the corresponding construction layer as needed during operation, effectively guaranteeing the construction progress. At the same time, the lifting design effectively reduces the overall height of the bracket, lightens the weight, and improves the safety factor.

[0015] A construction operation platform is also provided, including a ring-shaped main truss and a lifting hanger. Multiple extension trusses are provided at intervals along the circumference of the upper inner side of the main truss. Multiple lifting hangers are provided, and the multiple lifting hangers are respectively distributed below between two adjacent extension trusses. Two sets of vertical lifting devices at both ends of the main body of the hanger are respectively fixed to the lower ends of two adjacent extension trusses.

[0016] The beneficial effects of the construction operation platform of the present invention are as follows: It effectively improved the operational efficiency of the construction platform. Attached Figure Description

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] In this embodiment, the existing hanging system is suspended below the steel platform and can be raised as a whole with the platform. It is arranged parallel to one side of the construction wall to provide a working surface for workers to tie steel bars, install embedded parts, set up formwork, pour concrete and other construction operations.

[0025] See Figure 1 When installing an integrated platform, taking the nuclear island platform as an example, in order to prevent the initial installation position of the fulcrum from being too low and interfering with the construction of the surrounding plant A, the initial installation position of the fulcrum is raised. However, this also brings a problem: the initial position of the lowest working surface of the bracket (D in the figure) is higher than the structural layer B under construction. Therefore, it is necessary to increase the number of bracket layers to reduce the height of the working surface. This results in a large number of bracket layers, a high height, and a significant increase in self-weight. Whether installing or using large-volume brackets, it will inevitably lead to greater installation difficulty and more troublesome application. The safety risks of interconnection between multiple layers are also greater, and the production and use costs are significantly increased. The difficulty of later maintenance, upkeep, and dismantling after engineering technology is also increased.

[0026] See Figure 2After the integrated platform is lifted, taking the nuclear island platform as an example, the top working surface of the hanging frame (D in the figure) which serves as the material loading layer can efficiently transport materials and facilitate the construction of the structures on both sides. However, at this time, the vertical position of the hanging frame loading layer is higher than the structural layer B under construction, which cannot achieve efficient material transportation, thereby reducing construction efficiency. In this case, the traditional integrated platform cannot be lowered again, which means that the materials can only be transported slowly from the loading layer to the construction layer with difficulty, and there are safety hazards. This leads to a longer construction period and a significant increase in material transportation costs and time.

[0027] Based on the construction organization of the integrated platform, taking the nuclear island platform as an example, the construction plane of the inner and outer shells is divided into 12 segments (see...). Figure 3 , Figure 3 (Sections 1#, 2#...12#) Due to factors such as local penetrations, gates, and personnel organization, the construction progress of some sections is slower than others. When other sections are completed, the platform lifting time is delayed to provide working surfaces for the slower-progressing sections' scaffolding, directly slowing down the construction progress of other sections. If the platform is lifted, the scaffolding layer will be higher than the slower-progressing sections, requiring additional workers to catch up; otherwise, the progress of these sections will become increasingly slower, affecting the overall construction efficiency. In other words, when the progress of a section under construction slows down, construction of other sections must be stopped until completion before the entire integrated platform can be raised to match the continued construction of other faster-progressing sections, significantly reducing construction efficiency.

[0028] The lifting rack in this embodiment can flexibly move the rack up and down relative to the integrated platform, and can match any functional area of ​​the rack to the construction layer, effectively ensuring the construction progress. This lifting design solves the problems of existing racks having many layers, heavy weight, mismatch between the rack's loading surface and the structural construction layer, and the inability to lift in sections, which limits the overall progress. Through the core lifting principle design and safety and stability design, the rack lifting is safe, efficient, and stable.

[0029] For details, please refer to Figure 4 , Figure 5 and Figure 6 This application provides a lifting bracket, including a bracket body 1 and two sets of vertical lifting devices 2. The two sets of vertical lifting devices 2 operate synchronously to adjust the height of the bracket body 1, so that when used in conjunction with a construction work platform, the height of the bracket body 1 can be flexibly adjusted to match the current structural layer under construction.

[0030] Specifically, the two sets of vertical lifting devices 2 are connected to the top two ends of the main body 1 of the hanging frame, and the lifting and lowering of the main body 1 of the hanging frame is relatively stable.

[0031] In this embodiment, the main body 1 of the hanging rack can be configured with only two functional areas: a construction layer at the bottom and a material storage layer at the top. The lifting and lowering of the main body 1 allows the construction layer or storage layer to flexibly match the structural layer currently under construction, facilitating material transfer or construction. Compared to traditional hanging racks, the number of hanging rack layers is significantly reduced, the weight is significantly lowered, and the safety risks associated with lifting and lowering are reduced.

[0032] In some embodiments, an extendable working platform 11 that can be flipped up and down is provided on the side wall of each functional area on opposite sides of the main body 1. During operation, the extendable working platform 11 is flipped down to a horizontal state, so that the extendable working platform 11 is close to the structural layer B under construction. The extendable working platform 11 can serve as a connecting platform between the functional area of ​​the main body 1 and the structural layer under construction. The extendable working platform 11 fills the gap between the main body 1 and the structural layer under construction during operation, making the operation more convenient and safer.

[0033] Specifically, one edge of the extended work platform 11 is hinged to the bottom edge of the corresponding functional area of ​​the main body 1 via a pin. A cable is connected to each end of the extended work platform 11 on the upper part of the side wall of the functional area, and this cable is connected to the other edge of the extended work platform 11. When the extended work platform 11 is tilted down to the horizontal position, the cable straightens, providing safety protection for the extended work platform 11. Simultaneously, a narrow support platform (not shown in the figure) is provided at the bottom outer edge of each functional area of ​​the main body 1. When the extended work platform 11 is tilted down to the horizontal position, one side of it rests against the upper part of this support platform. This support platform restricts the extended work platform 11 from further tilting downwards, allowing it to tilt down only 90° to the horizontal position. Before the main body 1 of the bracket is raised or lowered, the extension work platform 11 can be manually pulled up and flipped upward. After the extension work platform 11 is flipped up and vertically abuts against the opening that fits the functional area side wall of the main body 1 of the bracket, the two ends of the extension work platform 11 are connected to the two ends of the opening by pins, so that the extension work platform 11 can be retracted.

[0034] Of course, the upward movement of the extended work platform 11 can also be driven by electric equipment. Specifically, a rope can be connected to the other edge of the extended work platform 11, and a winch device connected to the rope can be set in the upper part of the corresponding functional area inside the main body 1 of the hanging frame to realize the raising and lowering of the rope, thereby pulling up the extended work platform 11 or turning it down to the horizontal under the action of gravity.

[0035] In some embodiments, the vertical lifting device 2 includes a hoisting device, the lifting part of which is connected to the corresponding top end of the hanging frame body 1. The hoisting device may be an appropriate type of electric hoist, winch, etc. Taking an electric hoist as an example, the hoist's lifting rope is connected to the corresponding top end of the hanging frame body 1. Alternatively, a hanging ring is provided at the top of the corresponding end of the hanging frame body 1, and the electric hoist's lifting hook is engaged with the hanging ring.

[0036] Of course, each set of vertical lifting devices 2 can be equipped with two hoisting devices. Two columns are set at intervals along the width direction (that is, both sides) at both ends of the top of the main body of the hanging frame 1. The upper ends of the two columns are respectively connected to the lifting part of the hoisting device.

[0037] In some other embodiments, the vertical lifting device 2 may also be a hydraulic cylinder with a long stroke, etc.

[0038] In this embodiment, considering the issue of interconnection between adjacent functional areas, a climbing structure is provided in each functional area of ​​the main body 1 of the hanging rack, and a manhole passage is opened at the bottom of the upper functional area corresponding to the climbing structure.

[0039] The climbing structure can be a ladder installed on the inner wall of the main body 1 of the hanging frame, or it can be a step ladder installed inside the main body 1 of the hanging frame.

[0040] In this embodiment, the main body 1 of the hanging frame is equipped with a fall protection device 4. The fall protection device 4 is used to connect the main body 1 of the hanging frame with other carriers (such as construction work platforms) to ensure that in case of emergency, the main body 1 of the hanging frame will not separate from the carrier and fall under the action of the fall protection device 4, thus greatly improving safety.

[0041] In some embodiments, see Figure 7 The fall arrestor 4 includes two telescopic rods, which are vertically spaced at both ends of the top of the main body 1 of the bracket. Each telescopic rod has a limiting block 41 at its upper end. When used in conjunction with other carriers or construction platforms, the telescopic rods pass through the corresponding through holes of other carriers or construction platforms. The limiting block 41 is located above the through hole, and its cross-sectional size is larger than that of the through hole. In the event of an emergency fall, the main body 1 of the bracket falls, and the telescopic rods are automatically extended. However, after falling to a certain height, the limiting block 41 will be caught on other carriers or construction platforms, which can effectively prevent the main body 1 of the bracket from separating from other carriers or construction platforms and play a good fall arresting role.

[0042] In some other embodiments, the fall arrestor 4 may also be an additional safety rope, the two ends of which are connected to the two ends of the top of the main body 1 of the hanger. The safety rope passes through the carrier or other construction platform, and in the event of a fall risk, the safety rope can prevent the main body 1 of the hanger from separating from other carriers or construction platforms.

[0043] In some application scenarios, the main body 1 of the hanger is suspended below a portion of the carrier or construction platform. During operation, it extends between the inner and outer building walls, which can cause instability and swaying of the main body 1 during lifting and lowering. Therefore, an extended support frame 12 is installed on the main body 1, extending downwards. At the lower end of the extended support frame 12, there is a wall-supporting structure C that contacts both the inner and outer building walls. This wall-supporting structure prevents the main body 1 from swaying or shaking towards the inner and outer building walls. At the same time, this wall-supporting structure avoids uncast structural layers or structural layers with formwork, ensuring that the wall-supporting structure can operate relative to the smooth wall surface, without affecting the lifting and lowering of the hanger, while ensuring the smooth lifting and lowering of the main body 1.

[0044] In some embodiments, see Figure 8 The wall-supporting structure C includes horizontally telescopic devices 13 installed on both sides of the lower end of the heightened support frame 12. The telescopic ends of the two devices 13 are far apart and face the inner and outer building walls respectively. Each telescopic end of the device 13 is equipped with a rotatable support roller 14. After the two devices 13 are extended, the support rollers 14 can support the inner and outer building wall surfaces respectively. Since the support rollers 14 roll in contact with the wall surface, they can roll along the wall surface when the main body 1 of the bracket is raised or lowered, maintaining the stability of the main body 1 of the bracket without affecting its raising or lowering. Furthermore, the design of the telescopic devices 13 allows the wall-supporting structure to adapt to the support of inner and outer building walls with different spacing.

[0045] Specifically, the support roller 14 is rotatably mounted on the wheel frame, and the wheel frame is connected and fixed to the telescopic end of the telescopic device 13. The telescopic device 13 can be an electric push rod, hydraulic cylinder, or other suitable type.

[0046] Of course, in some other embodiments, the telescopic device 13 may be omitted, and a fixed-space support may be used instead. Specifically, an elastic floating member is provided on each side of the lower end of the heightened support frame 12. The wheel frame of the support roller 14 is mounted on the end of the elastic floating member. The elastic floating member may include a fixed sleeve, a movable sleeve, and a spring. One end of the fixed sleeve is fixedly connected to the corresponding side of the lower end of the heightened support frame 12 and points towards the wall. One end of the movable sleeve is inserted into the other end of the fixed sleeve, and the other end of the movable sleeve is fixed to the wheel frame of the support roller 14. The spring is sleeved on the outside of the fixed sleeve and the movable sleeve, and its two ends are respectively connected to the ends of the fixed sleeve and the movable sleeve that are far apart from each other. This elastic floating member allows the support roller 14 to adapt to local deformation of the wall and to closely adhere to the wall, ensuring good relative movement performance.

[0047] In some embodiments, the heightening support frame 12 adopts a separate design from the main body 1 of the hanging frame, that is, the heightening support frame 12 can slide up and down relative to the main body 1 of the hanging frame. When constructing the initial bottom structural layer, the heightening support frame 12 can be retracted upwards. At the same time, during installation, it can be retracted first to reduce its volume for easy installation, and then extended when in use. In addition, the heightening of the heightening support frame 12 can also avoid the template on the side of the construction layer, so that the support roller 14 at the lower end of the support frame 12 can be supported on the wall below the template.

[0048] Specifically, the main body 1 of the hanger has a channel for the vertical movement of the heightening support frame 12. Slider blocks are provided on opposite sides of the heightening support frame 12, and rails (which can be common components such as smooth rods) are provided on the inner walls of the channel on opposite sides. The sliders are slidably mounted on the rails, enabling the heightening support frame 12 to rise and fall relative to the channel. Simultaneously, a hoisting mechanism connected to the top of the heightening support frame 12 is provided at the top of the hanger body 1, driving the heightening support frame 12 to rise and fall relative to the hanger body 1.

[0049] The hoisting mechanism can be an electric hoist, a hydraulic cylinder, or a combination of a hoisting rope, a pulley block, and a power winch.

[0050] In some embodiments, the two ends of the main body 1 of the bracket are respectively equipped with heightening support frames 12. That is, the main body 1 of the bracket cooperates with the wall surface of the building through the wall-support structure at both ends, so that the lifting process of the main body 1 of the bracket is very stable and will not shake significantly.

[0051] In this embodiment, guardrails e are provided on both sides of the top of the main body 1 of the hanging rack. When the staff moves to the main body 1 of the hanging rack, they can be safely protected by the guardrails on both sides.

[0052] This embodiment also provides a construction operation platform, including a ring-shaped main truss 5 and a lifting hanger. This construction operation platform is mainly adapted to the construction operation of the containment vessel of the nuclear island platform. The containment vessel includes an inner shell and an outer shell. The main truss 5 is arranged around the outer shell and connected to a lifting system fixed to the outer shell wall. The lifting system can drive the main truss 5 to rise and fall relative to the containment vessel. Multiple extension trusses 51 are arranged at intervals along the circumference of the upper inner side of the main truss 5. A lifting hanger is arranged between the lower ends of every two adjacent extension trusses 51. Two sets of vertical lifting devices 2 of each lifting hanger are respectively installed at the lower ends of two adjacent extension trusses 51. During operation, the hanger body 1 is located between the inner shell and the outer shell of the containment vessel. As the hanger body 1 rises and falls, any functional area of ​​the hanger body 1 can be raised and lowered to the structural layer of the concrete being constructed at the top of the current inner shell and outer shell.

[0053] It should be noted that there is a gap between two adjacent hanging frame bodies 1 during operation. In order to ensure that workers can pass between the two hanging frame bodies 1, a manhole is provided at one end of the hanging frame body 1. A passage board is provided at the bottom of each functional area. The board can be pushed from one end of the hanging frame body 1 to the end of the adjacent hanging frame body 1 that is close to it, so that the board can overlap at the ends of the two hanging frame bodies 1, thereby allowing workers to pass through.

[0054] The following examples illustrate the construction platform of this embodiment using several real-world operational scenarios: Construction Operation Scenario 1 See Figure 10 During the installation of the construction platform, the initial installation position of the support point was too high (higher than the surrounding factory building A), causing a mismatch between the lower working layer of the main frame 1 and the structural layer B under construction. To avoid further increasing the number of layers, the main frame 1 was designed with a lifting structure. The lower working layer of the main frame 1 could be raised to the same level as the structural layer under construction (see...). Figure 9 This ensures the construction progress and also reduces the number of hanging rack layers, thus reducing the weight.

[0055] Construction Operation Scenario 2 See Figure 12 After the construction platform is lifted as a whole, there is a mismatch between the load layer of the hanging frame and the structural layer B under construction. To address this, and in order to avoid affecting the efficient transport of materials and reduce construction efficiency, the main body 1 of the hanging frame adopts a lifting structure, which can raise and lower the upper load layer of the hanging frame 1 to the same level as the structural layer under construction (see...). Figure 11 This ensures the progress of construction.

[0056] Construction Operation Scenario 3 The containment structure is being constructed in sections, with some sections progressing slowly. To avoid delaying the lifting time of the construction platform, the main body 1 of the scaffolding adopts a lifting structure. After the construction platform is lifted, the main body 1 of the scaffolding in the slower-progressing sections can be lowered to the same level as the upper load layer and the structural layer under construction, ensuring the construction progress. In other sections, the load layer or lower working layer of the main body 1 of the scaffolding is at a suitable height to the corresponding structural layer under construction.

[0057] In this embodiment, a force sensor can be installed at the connection between the lifting rope of the electric hoist and the main body 1 of the hanging frame to detect the weight of the main body 1 of the hanging frame in real time. The force sensor and the electric hoist are respectively connected to the control system, and the control system automatically matches the lifting speed of the main body 1 of the hanging frame to ensure low speed for heavy load and high speed for light load. At the same time, a path memory function for different working conditions can also be added to record the lifting position through the control system to achieve precise stopping at multiple points under different working conditions.

[0058] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
