Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and more specifically to a construction technology for prefabricated structures. Background Technology

[0002] Compared to the traditional bottom-up construction method, reverse construction is a top-down construction method. It involves lifting the prefabricated modular structure to the top design elevation and then gradually lifting the lower structure to the required elevation. This reduces the safety hazards caused by working at heights and greatly reduces the need for construction equipment to be raised along with the construction level.

[0003] Chinese patent application CN 118065512 A discloses a jacking construction device that breaks down a large concrete module structure into partially protruding modules and regular modules, transports them to the construction site, and then uses several jacking and limiting jacks in conjunction with the jacking openings and limiting openings on the large concrete module structure to jack and construct the large concrete module structure layer by layer.

[0004] However, the construction device provided by the above scheme has a complex structure and needs to be coordinated with two openings on the modular structure, resulting in low construction efficiency. At the same time, the modular structure of each layer needs to be disassembled and transported manually, and then coordinated with the lifting and limiting jacks, which results in a large workload and makes it difficult to guarantee the construction quality.

[0005] Therefore, how to effectively improve the transportation and construction efficiency of prefabricated structures, and ensure construction quality and reliability, has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a prefabricated structure transportation and reverse construction device and method with high transportation and construction efficiency, which can effectively improve construction quality and reliability.

[0007] To achieve the above objectives, the present invention provides a prefabricated structure transportation and reverse construction device, used in conjunction with prefabricated components, including a component prefabrication and transportation system, a lifting system, and a control system.

[0008] The jacking system is respectively installed on both sides of the component prefabrication and transportation system. Each jacking system includes a rigid support, a sliding bracket, and a jacking assembly. The sliding bracket is mounted on the rigid support and configured to move horizontally on the rigid support. The jacking assembly is mounted on the sliding bracket and configured to move vertically on the sliding bracket.

[0009] The component prefabrication and transportation system is configured to transport the prefabricated components and place them onto the lifting system, and is detachably connected to the lifting assembly.

[0010] The control system is configured to control the operating status of the lifting system and the component prefabrication and transportation system.

[0011] Furthermore, the rigid support is provided with a horizontal slide rail and a rack, and the sliding bracket is provided with sliding trusses at both ends that are adapted to the horizontal slide rail, and a gear that meshes with the rack is provided at the bottom.

[0012] Furthermore, the lifting assembly includes a lifting track and steel brackets distributed on the sliding support, wherein the steel brackets are slidably connected to the lifting track via bracket slots.

[0013] Furthermore, the lifting assembly also includes a lifting drive device, one end of which is connected to the rigid support and the other end of which is connected to the steel bracket.

[0014] Furthermore, the prefabricated component is provided with lifting holes for engaging with the steel bracket.

[0015] Furthermore, the component prefabrication and transportation system includes a crawling track and a transportation platform, wherein the transportation platform is slidably disposed on the crawling track and cooperates with the prefabricated component.

[0016] Furthermore, the component prefabrication and transportation system also includes a transportation drive device configured to drive the transportation platform to move on the crawling track.

[0017] Furthermore, the crawling track is equipped with a three-dimensional lifting device, which is configured to drive the transport platform to lift and move.

[0018] To achieve the above objectives, the present invention provides a prefabricated structure transportation reverse construction method, based on the prefabricated structure transportation reverse construction device, the transportation reverse construction method comprising:

[0019] The lifting system is symmetrically distributed on both sides of the component prefabrication and transportation system. The component prefabrication and transportation system transports the Nth layer of prefabricated components and places them above the lifting system.

[0020] The sliding bracket drives the lifting assembly to move horizontally on the rigid support, detachably connecting the lifting assembly to the Nth layer precast component. The lifting assembly moves vertically on the sliding bracket, synchronously lifting the Nth layer precast component.

[0021] The component prefabrication and transportation system transports the (N-1)th layer prefabricated component and places it above the lifting system, and performs minor horizontal adjustments on the (N-1)th layer prefabricated component. The lifting assembly lowers the Nth layer prefabricated component onto the (N-1)th layer prefabricated component and securely connects the Nth layer prefabricated component and the (N-1)th layer prefabricated component.

[0022] The sliding bracket drives the lifting assembly to move horizontally on the rigid support, disassembling the lifting assembly from the Nth layer prefabricated component. The lifting assembly then moves vertically on the sliding bracket, returning to its initial position, and then cooperates with the (N-1)th layer prefabricated component for lifting.

[0023] Furthermore, when the lifting assembly lifts the Nth layer of prefabricated components, and the component prefabrication and transportation system transports the (N-1)th layer of prefabricated components and places them above the lifting system, the height distance between the Nth layer of prefabricated components and the (N-1)th layer of prefabricated components is not less than 200mm.

[0024] The prefabricated structure transportation reverse construction device and method provided by the present invention transports prefabricated components through a component prefabrication and transportation system and cooperates with a jacking system. Compared with manual transportation alone, it can significantly reduce the amount of force and effectively improve the transportation efficiency of prefabricated components and the coordination accuracy with the jacking system. At the same time, through the relative movement and cooperation of rigid supports, sliding brackets and jacking components in the jacking system, the structure is not only simple, but also the prefabricated components can be quickly jacked, thereby effectively improving the construction quality and reliability.

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0043] See Figure 1 The image shows an example of the prefabricated structure transport reverse construction device provided by the present invention.

[0044] As shown in the figure, the prefabricated structure transportation reverse construction device in this example mainly includes a jacking system 100, a component prefabrication and transportation system 200, and a control system.

[0045] The lifting system 100 is respectively installed on both sides of the component prefabrication and transportation system 200. The lifting system 100 includes a rigid support 110, a sliding bracket 120 and a lifting component 130. The sliding bracket 120 is installed on the rigid support 110 and configured to move horizontally on the rigid support 110. The lifting component 130 is installed on the sliding bracket 120 and configured to move vertically on the sliding bracket 120, so that the lifting system 100 can cooperate with the component prefabrication and transportation system 200 to lift the prefabricated component 300.

[0046] In conjunction with this, the component prefabrication and transportation system 200 is configured to transport the prefabricated component 300 and place it onto the lifting system 100, and is detachably connected to the lifting assembly 130 to improve the transportation efficiency of the prefabricated component 300 and the fitting accuracy between the prefabricated component 300 and the lifting system 100.

[0047] Furthermore, the control system 300 is configured to control the working status of the jacking system 100 and the component prefabrication and transportation system 200 to ensure the construction quality and reliability of this transport reverse construction device.

[0048] Among them, the rigid supports 110 of the lifting system 100 are symmetrically arranged on both sides of the component prefabrication and transportation system 200, which facilitates cooperation with the component prefabrication and transportation system 200. This allows the component prefabrication and transportation system 200 to quickly place the prefabricated component 300 onto the rigid support 110 and cooperate with the lifting component 130, thereby improving the cooperation accuracy and transportation efficiency between the prefabricated component 300 and the lifting system 100.

[0049] Combination Figures 2 to 4 Furthermore, the rigid support 110 is provided with a horizontal slide rail 111, and the sliding bracket 120 is provided with sliding trusses 121 at both ends that are adapted to the horizontal slide rail 111, so that the sliding trusses 121 can be set on the horizontal slide rail 111 and slidably connected with the horizontal slide rail 111, thereby slidably connecting the sliding bracket 120 and the rigid support 110.

[0050] Meanwhile, the sliding truss 121 moves horizontally on the horizontal slide rail 111, which can drive the sliding support 120 to move horizontally in sync, thereby driving the lifting component 130 on the sliding support 120 to move in sync, realizing rapid connection and disassembly with the precast component 300, so as to improve construction efficiency.

[0051] To meet the construction height requirements, the sliding support 120 is usually quite high. Therefore, the sliding truss 121 is preferably configured to be the same height as the sliding support 120, so that the sliding support 120 and the sliding trusses 121 at both ends form a U-shaped distribution. While the sliding truss 121 drives the sliding support 120 to move horizontally, it can also ensure the movement stability of the sliding support 120 and enclose the lifting component 130 set on the sliding support 120 to prevent the operation of the lifting component 130 from being affected by the external environment, thereby ensuring construction quality and reliability.

[0052] Combination Figure 5 Furthermore, the rigid support 110 has racks 112 distributed along the direction of the horizontal slide rail 111. In cooperation with this, the bottom of the sliding bracket 120 is provided with a base plate 122, and the bottom of the base plate 122 is provided with a gear 123 that meshes with the racks 112. When the gear 123 rotates, it can work in conjunction with the racks 112 to drive the base plate 122 to move synchronously along the racks 112, thereby driving the sliding bracket 120 and the sliding truss 121 to move synchronously horizontally on the horizontal slide rail 111.

[0053] Meanwhile, a drive motor 124 is provided on the base plate 122. The output shaft of the drive motor 124 extends to the bottom of the base plate 122 and is connected to the gear 123, so that the rotation of the drive motor 124 can drive the gear 123 to rotate, thereby realizing the synchronous horizontal movement of the sliding bracket 120.

[0054] Combination Figures 2 to 4 In conjunction with this, the lifting assembly 130 includes a lifting track 131 and a steel bracket 132. The lifting track 131 is distributed along the height direction on the sliding support 120. The steel bracket 132 is slidably connected to the lifting track 131 through a bracket slot 133, so that the bracket slot 133 can drive the steel bracket 132 to move vertically along the lifting track 131, thereby enabling the lifting assembly 130 to move vertically on the sliding support 120, so as to realize the lifting construction of the precast component 300 by the lifting assembly 130.

[0055] As a preferred configuration, the bracket slot 133 and the lifting track 131 are configured to slide in a dovetail shape to ensure the stability of the steel bracket 132 and prevent it from shifting during vertical movement, thereby ensuring the construction quality of the precast component 300.

[0056] Furthermore, the lifting assembly 130 also includes a lifting drive device 134. Preferably, the lifting drive device 134 is composed of a lifting hydraulic cylinder. The lifting hydraulic cylinder is connected to a hydraulic pump station through a high-pressure oil pipe. One end of the lifting hydraulic cylinder is connected to a rigid support 110, and the other end is connected to the lower part of the steel bracket 132. This allows the extension and retraction of the lifting hydraulic cylinder to drive the steel bracket 132 to move vertically along the lifting track 131, thereby lifting the precast component 300.

[0057] Meanwhile, a pressure sensor 135 is also provided on the steel bracket 132, which can detect the pressure applied by the precast component 300 to the steel bracket 132 in real time and transmit the pressure value to the control system. The control system can then control the working state of the lifting drive device 134 according to the corresponding pressure value, such as controlling the pressure and flow rate of the high-pressure oil in the lifting hydraulic cylinder, thereby providing sufficient driving force for the steel bracket 132 and ensuring that the steel bracket 132 can stably lift the precast component 300 to the required position.

[0058] In some embodiments, the lifting hydraulic cylinder is also provided with a safety protection device. For example, the safety protection device can be composed of an existing safety relief valve and a pressure sensor 135, so that the pressure sensor 135 can transmit the pressure value of the steel bracket 132 to the safety relief valve in real time. When the pressure value exceeds the preset pressure threshold, the safety relief valve can open to overload protect the lifting hydraulic cylinder and prevent damage to the lifting hydraulic cylinder.

[0059] Combination Figures 6 to 9 Correspondingly, the precast component 300 is provided with lifting holes 310 on both sides. The lifting holes 310 are adapted to the steel brackets 132, and the initial position of the rigid component 130 corresponds to the setting position of the lifting holes 310. This allows the sliding bracket 120 to move horizontally on the rigid support 110 towards the precast component 300, which in turn drives the rigid component 130 to move horizontally synchronously, directly and accurately inserting the steel brackets 132 into the lifting holes 310 of the precast component 300. Figure 1 As shown, this allows for a detachable connection between the rigid component 130 and the prefabricated component 300, while simultaneously improving the accuracy and efficiency of the connection between the lifting component 130 and the prefabricated component 300.

[0060] Combination Figure 10 Furthermore, the lifting drive device 134 drives the steel bracket 132 to move vertically away from the rigid support 110 on the sliding bracket 120, and can drive the precast component 300 to move vertically away from the rigid support 110 simultaneously through the lifting hole 310, thereby carrying out the lifting construction of the precast component 300.

[0061] Combination Figure 11 and Figure 12 At that time, the prefabricated components of the next layer are transported to the bottom of the prefabricated components of the previous layer that have been lifted by the component prefabrication and transportation system 200. The lifting drive device 134 drives the steel bracket 132 to move vertically on the sliding support 120 toward the rigid support 110, so that the prefabricated components of the previous layer can be placed on the prefabricated components of the next layer. If the pressure sensor 135 detects that the pressure value of the steel bracket 132 is zero, it means that the prefabricated components of the previous layer and the prefabricated components of the next layer have been stably connected.

[0062] Combination Figure 13 and Figure 14 At this time, the two adjacent precast components 300 are fixedly connected to realize the construction of the upper and lower precast components. The sliding bracket 120 moves horizontally on the rigid support 110 in a direction away from the precast component 300, driving the rigid component 130 to move horizontally synchronously, so that the steel bracket 132 is removed from the lifting hole 310 of the precast component 300, so as to realize the disassembly of the rigid component 130 and the precast component 300, and continue the lifting construction of the next layer of precast components, thereby improving the construction efficiency.

[0063] The jacking system 100 thus constitutes a lifting system that, through the cooperation of rigid support 110, sliding bracket 120 and jacking component 130, enables the horizontal and vertical movement of the jacking component 130 and allows for precise, rapid and detachable connection with the precast component 300 to perform jacking construction on the precast component 300, thereby ensuring construction quality and reliability.

[0064] In order to facilitate the rapid transport of precast components 300 and enable them to quickly and accurately engage with the jacking system 100, thereby improving construction efficiency, this transport and reverse construction device also includes a component prefabrication and transport system 200. The component prefabrication and transport system 200 is configured to transport the precast components 300 and place them onto the jacking system 100, allowing the precast components 300 and the jacking assembly 130 to be detachably connected and engaged, thereby improving the transport efficiency of the precast components 300 and the engagement accuracy between the precast components 300 and the jacking system 100.

[0065] Combination Figure 1 Specifically, the component prefabrication and transportation system 200 includes a crawling track 210 and a transportation platform 220. The crawling track 210 is distributed along the length direction between two symmetrical lifting systems 100 and abuts against the rigid support 110. The transportation platform 220 is slidably disposed on the crawling track 210 and cooperates with the prefabricated component 300, so that the transportation platform 220 can drive the prefabricated component 300 to move on the crawling track 210, transport the prefabricated component 300 and place it above the rigid support 110, so that the prefabricated component 300 can quickly cooperate with the lifting assembly 130, improving transportation efficiency and cooperation accuracy.

[0066] Combination Figure 15 Furthermore, the width of the crawling track 210 and the transport platform 220 is slightly larger than the distance between the two lifting systems 100 and is adapted to the width of the precast component 300, so that the component precasting and transport system 200 is placed on one side of the lifting system 100 and abuts against the rigid support 110. In this way, the transport platform 220 can transport the precast component 300 to one side of the lifting system 100 through the crawling track 210 and place the precast component 300 above the rigid support 110.

[0067] In some embodiments, the transport platform 220 may also consist of two sets of transport platforms 220 distributed at both ends of the crawling track 210 and moving synchronously along the crawling track 210. The two sets of transport platforms 220 respectively carry the bottom columns at both ends of the prefabricated component 300, so that the two sets of transport platforms 220 move synchronously to transport the prefabricated component 300 to the lifting system 100.

[0068] In some embodiments, the transport platform 220 is also pre-embedded with a positioning sleeve that cooperates with the precast component 300. The precast component 300 can be reinforced, formwork erected, concrete poured and cured on the transport platform 220, so that the precast component can be prefabricated directly on the transport platform 220. This facilitates the direct transport of the precast component from the nomadic production area to the lifting system 100 for lifting, thereby improving transport efficiency.

[0069] Combination Figures 15 to 17 Furthermore, the component prefabrication and transportation system 200 also includes a transportation drive device 230. Preferably, the transportation drive device 230 is composed of a hydraulic crawler traction device. One end of the hydraulic crawler traction device is connected to the crawling track 210, and the other end is connected to the transportation platform 220, so that the hydraulic crawler traction device can extend and retract to pull the transportation platform 220 to move on the crawling track 210, so as to realize the rapid transportation of the prefabricated component 300.

[0070] Meanwhile, the end of the transport platform 220 that cooperates with the crawling track 210 is also provided with a slipper 221. The slipper 221 is slidably connected to the crawling track 21, so that the hydraulic crawling traction device can drive the transport platform 220 to move axially along the crawling track 210 through the slipper 221, preventing the transport platform 220 from shifting and thus ensuring the fitting accuracy between the precast component 300 and the lifting system 100.

[0071] To ensure transportation reliability, the transportation platform 220 is also equipped with an anti-collision device. For example, the anti-collision device can be composed of existing ultrasonic sensors and an automatic braking system. The ultrasonic sensors detect the distance between the transportation platform 220 and surrounding objects and the lifting system 100 in real time, and transmit the distance data to the automatic braking system. When the distance between the transportation platform 220 and the lifting system 100 is small, the automatic braking system can control the transportation drive device 230 to stop working, thereby stopping the movement of the transportation platform 220 and preventing the transportation platform 220 from colliding with surrounding objects and the lifting system 100, so as to ensure the transportation stability of the prefabricated component 300.

[0072] In this way, the transport platform 200 can move axially between the two sets of lifting systems 100 along the crawling track 210. When the transport platform 200 moves to abut against the rigid support 110 of the lifting system 100, the precast component 300 is transported into place and can cooperate with the lifting system 100.

[0073] Combination Figure 17 In order to stably place the precast component 300 above the rigid support 110, three-dimensional lifting devices 211 are distributed at both ends of the crawling track 210. The three-dimensional lifting devices 211 are preferably composed of existing three-dimensional hydraulic cylinders and are connected to the bottom of the transport platform 220, so that the three-dimensional lifting devices 211 can lift the transport platform 220 and drive the transport platform 220 to move towards the lifting system 100, so that the transport platform 200 is placed above the rigid support 110, thereby driving the precast component 300 to be placed simultaneously above the rigid support 110.

[0074] At the same time, the three-dimensional lifting device 211 drives the transport platform 200 to make slight adjustments in the horizontal direction, so that the prefabricated component 300 can be precisely matched with the lifting system 100.

[0075] Combination Figure 18 At this time, the lifting drive device 134 of the lifting system 100 drives the steel bracket 132 to move vertically on the sliding bracket 120, so that the steel bracket 132 corresponds to the lifting hole 310 of the precast component 300. At the same time, the sliding bracket 120 moves horizontally on the rigid support 110 toward the precast component 300, so that the steel bracket 132 is directly and accurately inserted into the lifting hole 310 of the precast component 300, thereby making the precast component 300 completely fall on the steel bracket 132 and connect with the lifting system 100.

[0076] Furthermore, the lifting system 100 lifts the precast component 300, and the three-dimensional lifting device 211 drives the transport platform 200 back to its initial position, ready to transport the next precast component 300.

[0077] The component prefabrication and transportation system 200 thus constitutes a component prefabrication and transportation system 200, which, through the cooperation of crawling rail 210, transportation platform 220 and transportation drive device 230, can quickly and stably transport prefabricated components 300, thereby improving the transportation efficiency and construction efficiency of prefabricated components 300.

[0078] Furthermore, this transport reverse construction device also includes a control system, which is configured to control the working status of the jacking system 100 and the component prefabrication and transport system 200, so as to ensure that the transport and jacking of the prefabricated components 300 can cooperate with each other, improve construction efficiency, and ensure construction quality and reliability.

[0079] Specifically, the control system is connected to the lifting drive device 134 of the lifting system 100 and the transport drive device 230 of the component prefabrication and transport system 200. By controlling the extension and retraction stroke and direction of the lifting drive device 134 and the transport drive device 230 respectively, the lifting height and transport path of the prefabricated component 300 can be controlled accordingly.

[0080] Furthermore, the control system can also preset the movement path of the transport drive device 230 to ensure that the transport platform 220 can accurately transport the prefabricated component 300 to the corresponding position of the lifting system 100, thereby achieving the positioning of the transport platform 220 and improving the matching accuracy between the prefabricated component 300 and the lifting system 100.

[0081] Here, the control system can be composed of an existing PLC control cabinet or a remote control device to achieve stable operation of this transport reversing device.

[0082] This constitutes the prefabricated structure transportation reverse construction device provided by the present invention.

[0083] This invention also provides a method for transporting and reversing prefabricated structures, based on a prefabricated structure transport and reversing construction device constructed using the above-mentioned scheme, combined with... Figures 9 to 13 The reverse construction method for this transport includes:

[0084] First, the jacking system 100 is symmetrically distributed on both sides of the component prefabrication and transportation system 200, so that the component prefabrication and transportation system 200 can transport the prefabricated component 300 and cooperate with the jacking system 100. The component prefabrication and transportation system 200 transports the Nth layer prefabricated component 301 and places it above the rigid support 110 of the jacking system 100.

[0085] Combination Figure 1 Specifically, the Nth layer prefabricated component 301 is placed on the transport platform 220, and the transport drive device 230 pulls the transport platform 220 to move on the crawling track 210 to transport the Nth layer prefabricated component 301 to the corresponding position of the lifting system 100, and the Nth layer prefabricated component 301 is placed above the rigid support 110 by the three-dimensional lifting device 211.

[0086] Next, the sliding bracket 120 drives the lifting component 130 to move horizontally on the rigid support 110, detachably connecting the lifting component 130 to the Nth layer prefabricated component 301. The lifting component 301 moves vertically on the sliding bracket 120, simultaneously lifting the Nth layer prefabricated component 301.

[0087] Specifically, the initial position of the lifting assembly 301 corresponds to the lifting hole 310. The sliding truss 121 drives the sliding bracket 120 to move horizontally on the horizontal slide rail 111 of the rigid support 110 toward the precast component 300, which drives the rigid assembly 130 to move horizontally in sync. This allows the steel bracket 132 to be directly and accurately inserted into the lifting hole 310 of the Nth layer precast component 301, making the lifting assembly 301 and the Nth layer precast component 301 detachably connected.

[0088] The jacking drive device 134 then drives the steel bracket 132 to move vertically away from the rigid support 110 on the jacking track 131 of the sliding support 120. This allows the Nth layer precast component 301 to move vertically away from the rigid support 110 simultaneously through the jacking hole 310, thereby performing jacking construction on the Nth layer precast component 301. Figure 9 As shown.

[0089] Next, the component prefabrication and transportation system 200 transports the N-1th layer prefabricated component 302 and places it above the rigid support 110 of the lifting system 100, and performs a horizontal fine adjustment on the N-1th layer prefabricated component 302. The lifting assembly 130 lowers the Nth layer prefabricated component 301 onto the N-1th layer prefabricated component 302 and fixes the Nth layer prefabricated component 301 and the N-1th layer prefabricated component 302 together.

[0090] Specifically, the component prefabrication and transportation system 200 transports the N-1th layer prefabricated component 302 in the same way and places it above the rigid support 110 of the jacking system 100. Then, the three-dimensional jacking device 211 performs horizontal fine-tuning on the N-1th layer prefabricated component 302 to align the N-1th layer prefabricated component 302 with the Nth layer prefabricated component 301, so as to avoid unevenness between the upper and lower layers of the facade.

[0091] At this point, the Nth layer precast component 301 has been lifted above the (N-1)th layer precast component 302. It is necessary to ensure that the height distance between the Nth layer precast component 301 and the (N-1)th layer precast component 302 is not less than 200mm to prevent collision damage and ensure construction quality and reliability. Figure 11 As shown.

[0092] At this time, the lifting drive device 134 drives the steel bracket 132 to move vertically on the lifting track 131 of the sliding support 120 towards the rigid support 110, lowering the Nth layer precast component 301 above the (N-1)th layer precast component 302. When the pressure sensor 135 on the steel bracket 132 detects that the pressure on the steel bracket 132 is zero, it indicates that the Nth layer precast component 301 and the (N-1)th layer precast component 302 have been stably contacted. Figure 12 As shown.

[0093] The Nth layer precast component 301 is fixedly connected to the N-1th layer precast component 302 by means of a fastener, such as a fastener screw, so as to complete the construction of the Nth layer precast component 301.

[0094] Next, the sliding bracket 120 drives the lifting component 130 to move horizontally on the rigid support 110, disassembling the lifting component 130 from the Nth layer prefabricated component 301. The lifting component 130 moves vertically on the sliding bracket 120, returns to its initial position, and then cooperates with the (N-1)th layer prefabricated component 302 for lifting.

[0095] Specifically, the sliding truss 121 drives the sliding support 120 to move horizontally away from the precast component 300 on the horizontal slide rail 111 of the rigid support 110, which drives the rigid component 130 to move horizontally in sync, so that the steel bracket 132 can be withdrawn directly from the lifting hole 310 of the Nth layer precast component 301, and the lifting component 301 can be disassembled from the Nth layer precast component 301.

[0096] Next, the jacking drive device 134 drives the steel bracket 132 to move vertically along the jacking track 131 of the sliding support 120 towards the rigid support 110, moving the steel bracket 132 to its initial position, ready to perform jacking construction on the (N-1)th layer precast component 302, as follows. Figure 13 As shown.

[0097] Correspondingly, the initial position of the lifting assembly 301 corresponds to the lifting hole 310. The sliding truss 121 drives the sliding bracket 120 to move horizontally on the horizontal slide rail 111 of the rigid support 110 towards the precast component 300, driving the rigid assembly 130 to move horizontally synchronously. This allows the steel bracket 132 to be directly and accurately inserted into the lifting hole 310 of the (N-1)th layer precast component 302, making the lifting assembly 302 detachably connected to the (N-1)th layer precast component 302 and enabling the lifting of the (N-1)th layer precast component 302. Figure 14 As shown.

[0098] The prefabricated component of the N-2 layer is then transported by the component prefabrication and transportation system 200 and placed above the rigid support 110 of the jacking system 100. The jacking component 130 lowers the prefabricated component 302 of the N-1 layer onto the prefabricated component of the N-2 layer and fixes the prefabricated component 302 of the N-1 layer and the prefabricated component of the N-2 layer to complete the construction of the prefabricated component 302 of the N-1 layer.

[0099] Repeat the above steps until the transportation and jacking of all precast components is completed.

[0100] The prefabricated structure transportation reverse construction device and method provided by the present invention, through the cooperation of component prefabrication and transportation system 100, jacking system 200 and control system with prefabricated component 300, can realize the rapid transportation of prefabricated component 300 and precise cooperation with jacking system 20, improve transportation and construction efficiency, and ensure construction quality and reliability.
