[0002] With the continuous development of my country's construction industry, more and more high-rise residential buildings are appearing in people's field of vision. Traditional super high-rise construction jacking formwork systems have high integration, large overall load, and high investment costs.

[0003] For prefabricated housing projects, when multiple buildings are simultaneously hoisting and transporting prefabricated components, tower cranes cannot meet the needs of simultaneous hoisting operations on multiple work surfaces. In addition, during the construction process, it is necessary to transport aluminum formwork panels, auxiliary materials, and prefabricated components from the floors to various construction sites. Currently, material transportation within the operating floor mainly relies on manual labor, which results in slow speed and low efficiency. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a control method for a prefabricated housing intelligent construction platform to solve the problems.

The gantry assembly includes an upward gantry assembly installed on the upward slide and a downward gantry assembly installed on the downward slide; the upward gantry assembly and the downward gantry assembly are arranged in parallel; the upward gantry assembly and the downward gantry assembly are respectively equipped with a first laser rangefinder group and a second laser rangefinder group. The control method includes the following steps; S1; Connect the movable end of the upward gantry crane assembly to the material on the ground through the floor slab, and gradually increase the lifting speed of the upward gantry crane assembly to lift the material to a first predetermined height. Then gradually decrease the lifting speed to pass through the floor slab to reach the maximum height of the upward gantry crane assembly. The first predetermined height is obtained by measuring the distance with the first laser rangefinder group. The first predetermined height is 5 to 10 meters below the floor slab. S2, control the upward gantry crane assembly to move laterally along the slide rail assembly at its maximum height to the first designated unloading area for unloading; S3, after unloading is completed, control the upward gantry crane assembly to leave the first designated unloading area; then control the downward gantry crane assembly to move laterally along the track assembly to the first designated unloading area to connect with the material and transport it to the second designated unloading area.

[0006] Preferably, in step S1, during the process of connecting the movable end of the upward gantry crane assembly to the material on the ground through the floor slab and gradually increasing the lifting speed of the upward gantry crane assembly to lift the material to the first predetermined height, the lateral movement function of the upward gantry crane assembly is locked to prevent human error.

[0007] Preferably, in step S2, during the process of controlling the upward gantry crane assembly to move laterally along the maximum height to unload material in the first designated unloading area, it is determined whether the downward gantry crane assembly is in the first designated unloading area. If it is, the upward gantry crane assembly is controlled to move laterally to wait outside the first designated unloading area; otherwise, the upward gantry crane assembly is controlled to move laterally directly to the first designated unloading area.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-6 This invention provides a control method for a prefabricated housing intelligent construction platform: the prefabricated housing intelligent construction platform includes a Bailey bridge platform 1, a support frame 3, a gantry assembly, and a track assembly 5; the support frame 3 is installed at the bottom of the Bailey bridge platform 1, and a floor slab 2 is provided on the upper side of the support frame 3; the floor slab 2 is mainly used for workers to stand on and for placing building materials, and the way the floor slab 2 is built and fixed to the support frame 3 is a conventional technology, so it will not be described in detail in this specification.

[0016] The Bailey bridge platform 1 includes several Bailey bridge sections 11 and connecting fittings 12 for connecting the Bailey bridge sections 11. The several Bailey bridge sections 11 form at least two lifting shafts A through the connecting fittings 12, wherein the connecting fittings 12 are conventional hardware fittings used for connecting and fixing the various Bailey bridge sections 11 to each other. The Bailey bridge platform 1 is used to build an external hanging frame (not shown in the figure), which is mainly hung on the Bailey bridge sections 11 as a protective structure and a working surface for construction.

[0017] The track assembly 5 is installed on the Bailey bridge platform 1 and the support frame 3, and is provided with an upward slide 51 and a downward slide 52. The upward slide 51 and the downward slide 52 are both fixed on a base frame 4. The base frame 4 is set on the staggered support frames 3, and the base frame 4 has two inwardly extending first mounting parts 41 and second mounting parts 46. The upward slide 51 and the downward slide 52 are respectively installed on their respective first mounting parts 41 and second mounting parts 46. Preferably, the support frames 3 are staggered and fixed below the Bailey bridge platform 1. The staggered method allows the installation position of the support frames 3 to be selected according to the terrain, avoiding the need for additional terrain leveling before construction. Secondly, it can be more evenly distributed inside the building, making the load-bearing more balanced and reducing the unevenness of the structure. Thirdly, since the base frames 4 are installed on the support frames 3, the base frames 4 are also staggered, which facilitates the operation of the downward gantry assembly to be used inside the building later.

[0018] The support frame 3 is a hydraulic cylinder support column, which is connected to the wall 33 via a wall-mounted guide seat 32. The hydraulic cylinder support column has several hydraulic cylinders 34 and a support column 31; the hydraulic cylinders 34 are mounted on the support column 31, and their tails are movably connected to the support column 31 via hinges. The support column 31 has several vertically distributed slots 311. The piston hinge of the hydraulic cylinder 34 has a connecting arm 35, which is inserted into the slot 311 until it is hinged to the wall-mounted guide seat 32. Thus, when the piston of the hydraulic cylinder 34 extends forward, the connecting arm 35 presses against the slot 311, thereby causing the support column 31 to move upward.

[0019] The top of the supporting column 31 is a lattice column 32, which strengthens the structure and provides good support.

[0020] Furthermore, a base 13 is fixed to the top of the lattice column 32, and the base 13 has a mounting end face 131 on which the Bailey bridge platform 1 will be mounted. In one embodiment, the base 13 is square, and the side length of the base 13 is greater than the width of the Bailey bridge platform 1 it contacts. This increases the load-bearing area of ​​the base 13, providing better support for the Bailey bridge platform 1. Additionally, the base 13 has multiple regularly arranged perforated through holes 132, which ensures the structural stability of the base 13 and also makes the base 13 lightweight.

[0021] The first mounting part 41 of the upward slide rail 51 is the main stress point. The first mounting part 41 is fixed to the mounting end face of the base 13 by bolts and washers, thus securing the first mounting part 41 to the base 13 and providing conditions for the installation of the upward slide rail 51. It is worth noting that the first mounting part 41 is placed on the Bailey bridge plate 11 at the bottom of the Bailey bridge platform 1, and then fixed to the base 13 by bolts and washers. This avoids conflict between the installation of the first mounting part 41 and the Bailey bridge platform 1 on the base 13, and the fixation of the first mounting part 41 to the base 13 creates a clamping effect on the Bailey bridge platform 1, enhancing the fixation strength between the Bailey bridge platform 1 and the base 13. The outer bottom of the first mounting part 41 of the upward slide rail 51 is fixed to the second mounting part 46 (which is used for the installation of the downward slide rail 52) by a sleeve assembly and bolts. Specifically, the sleeve assembly consists of insert rods 43 and sleeves 44. The insert rods 43 are provided in several parts and divided into two groups. The two groups of insert rods 43 are vertically fixed on the first mounting part 41 and the second mounting part 46, respectively. The sleeves 44 are hollow, so that the insert rods 43 can be inserted into the sleeves 44 to form a connection. Furthermore, a hole 45 for bolt insertion is reserved on both the insert rods 43 and the sleeves 44. In this way, the insertion rods 43 and the sleeves 44 are fixed by bolts, thereby achieving the purpose of fixing the second mounting part 46 of the downward slide 52 to the first mounting part 41 of the upward slide 51. It is worth mentioning that the lengths of both the first mounting portion 41 and the second mounting portion 46 are greater than the side length of the base 13, so as to provide sufficient space for the corresponding track assembly 5 to be installed. Preferably, the lengths of the first mounting portion 41 and the second mounting portion 46 extending beyond the side length of the base 13 are 3 to 5 times the length of the track assembly 5 to be installed. This provides sufficient length for the track assembly 5 to be rotated to a suitable position for installation, while avoiding structural strength problems and deformation under stress caused by excessively long first mounting portions 41 and second mounting portions 46. In one embodiment, the length of the first mounting portion 41 for mounting the upward slide 51, which is the main stress point, extending beyond the side length of the base 13 is 3 times the width of the upward slide 51, while the length of the second mounting portion 46 for mounting the downward slide 52 extending beyond the side length of the base 13 is 4 times the length of the downward slide 52.

[0022] The gantry crane assembly includes an upward gantry crane assembly installed on the upward slide rail 51 and a downward gantry crane assembly installed on the downward slide rail 52. The upward gantry crane assembly is arranged parallel to the downward gantry crane assembly and is located above the downward gantry crane assembly. The upward gantry crane assembly includes an upward gantry crane 61, an upward sliding device 62, and an upward lifting device 63. The upward gantry crane 61 is installed on the upward slide rail 51, and the upward sliding device 62 is installed on the upward gantry crane 61. The upward gantry crane 61 drives the upward sliding device 62 and the upward lifting device 63 to move along the upward slide rail 51. The upward sliding device 62 is used to move the upward lifting device 63 on the upward gantry crane 61. The lifting end of the upward lifting device 63 is connected to the material X, and the material X is lifted mainly by retracting the steel cable. The upward gantry crane 61, the upward sliding device 62, and the upward lifting device 63 are existing conventional equipment that can be purchased directly from the market, so they will not be described in detail in the instruction manual. However, it is worth mentioning that the upward gantry crane 61, the upward sliding device 62, and the upward lifting device 63 are all controlled by a control unit (not shown in the figure) mainly composed of a PLC controller, and a laser rangefinder group 7 is installed on the upward gantry crane 61 to collect the position information of the material X. The specific method is described in the control method below.

[0023] Similarly, the descending gantry crane assembly includes a descending gantry crane 64, a descending sliding device 65, and a descending lifting device 66; the descending gantry crane 64 is mounted on the descending slide rail 52; and the descending sliding device 65 is mounted on the descending gantry crane 64 to allow the descending lifting device 66 to move on the descending gantry crane 64; the lifting end of the descending lifting device 66 is connected to the material X. The descending gantry crane assembly is the same as the ascending gantry crane assembly, and the descending gantry crane 64, descending sliding device 65, and descending lifting device 66 can all be purchased commercially, and the descending gantry crane 64 is also equipped with a laser rangefinder assembly 7 and its control unit.

[0024] The installation methods for the intelligent construction platform for prefabricated housing include: Step 1: Assemble the support frame 3 and the wall 33. This is done by installing wall-mounted guide seats 32 on the wall 33 and securing them with pins. Then, the support column 31 is hinged to the wall-mounted guide seats 32. The lifting and lowering of the support column 31 can be achieved by extending and retracting the piston of the hydraulic cylinder 34, which is used for subsequent adjustment of the overall Bailey bridge platform 1's level.

[0025] Step 2: Construct a Bailey bridge platform 1 on top of the support frame 3; install track components 5 on the Bailey bridge platform 1 and the support frame 3 for the movement of the gantry crane components; based on Step 1, install a base 13 on top of the hydraulic cylinder support column, and then assemble the Bailey bridge sections 11 by connecting them with connecting accessories 12 according to construction requirements, while reserving at least two lift shafts A. Install a base frame 4 on the base 13 with bolts, and then install an upward slide rail 51 and a downward slide rail 52 on the base frame 4 for the movement of the gantry crane components. Constructing the Bailey bridge platform 1 by gradually increasing its height ensures the overall structural strength of the construction platform, reduces construction difficulty, and allows for the reservation of lift shafts A according to the construction terrain, thus planning the running direction of the gantry crane components and shortening the construction period.

[0026] Step 3: Install the upward gantry assembly on the upward slide 51, and connect the movable end of the upward gantry assembly to the material X on the ground through the floor slab 2. Construct the floor slab 2 on the cylinder support column. The floor slab 2 can be made of steel mesh commonly used in the construction industry, and the meshes are spliced ​​together to form a floor layer. Preferably, the floor slab 2 is constructed on the support column 31, as the support column 31 has multiple slots, making it easier to fix the floor slab 2 and reducing construction difficulty. It is worth noting that the width of the floor layer must be less than the width of the Bailey bridge platform 1, so that the elevator shaft A reserved in step 2 is placed on the outside of the floor layer. This allows the steel cable and hook of the upward lifting device 63 to smoothly extend from the elevator shaft A to the ground. Furthermore, an elevator shaft 21 must be reserved in the floor slab 2 for installing a building elevator for construction personnel to move up and down.

[0027] The control method includes the following steps; S1; The movable end of the upward gantry crane assembly is connected to the material X on the ground through the lifting shaft A of the floor slab 2, and the lifting speed is gradually increased to the maximum lifting speed of the upward gantry crane assembly to lift the material X to a first predetermined height H1. Then, the lifting speed is gradually reduced to pass through the floor slab 2 to reach the maximum height H2 of the upward gantry crane assembly. The movable end of the upward gantry crane assembly is a hook in the upward lifting device 63, through which the material X is connected. The first predetermined height H1 is obtained by measuring distance using the first laser rangefinder group 7. In one embodiment, the first predetermined height H1 is 5-10 meters below the floor slab, preferably about 7 meters below the floor slab. The maximum height H2 is the rated maximum height H2 that the upward lifting device 63 needs to lift. In one embodiment, the maximum height H2 is 3-4 meters above the floor slab.

[0028] It is worth mentioning that each of the first and second laser rangefinder groups 7 contains at least two laser rangefinders. The two rangefinders in the first group 7 correspond to the ground and the horizontal line respectively, thus measuring the first predetermined height H1 and the distance displaced along the track assembly 5. The two rangefinders in the second group 7 correspond to the floor slab 2 and the horizontal line respectively, thus measuring the lifting height of the material and the distance displaced along the track assembly 5. After the upward gantry crane assembly connects to material X, the lifting speed gradually increases from the minimum lifting speed (minimum lifting speed is zero) to the maximum lifting speed of the upward gantry crane assembly, lifting material X to a first predetermined height H1. The transition from the minimum to the maximum lifting speed occurs during the first 20% of the height from the first predetermined height H1. This initial 20% lifting speed ensures a stable ascent of material X, preventing the steel cable from breaking due to sudden stress or the material X from shaking due to sudden stress. In the latter part of the first predetermined height H1, the material X is lifted at the maximum lifting speed of the upward gantry crane assembly. This ensures that material X is lifted at a uniform speed during this stage, resulting in faster lifting and reduced hoisting time. Furthermore, the uniform speed of the material X during lifting makes the process smoother and more stable, reducing swaying.

[0029] In step S1, the step of gradually reducing the lifting speed to pass through the floor slab 2 and reach the maximum height H2 of the upward gantry assembly specifically includes: gradually reducing the lifting speed to 20% of the maximum lifting speed to pass through the floor slab 2 smoothly, and then reducing the lifting speed to zero when the maximum height H2 of the upward gantry assembly is reached.

[0030] In one embodiment, the first predetermined height H1 is 7 meters below the floor slab, and the maximum height H2 is 1 meter above the floor slab. The buffer height H3 is obtained by subtracting the first predetermined height H1 from the maximum height H2. The buffer height H3 is mainly to turn the material X that has reached the maximum lifting speed to the minimum speed so that it can be unloaded later.

[0031] S2, control the upward gantry crane assembly to move laterally along the slide rail assembly at its maximum height H2 to the first designated unloading area B for unloading. The first designated unloading area B is a location on the floor slab 2 designated for unloading or storing material X. Preferably, the first designated unloading area B is set at a predetermined distance from the elevator shaft A. This shortens the lateral movement distance of the upward gantry crane assembly, i.e., the time spent on lateral movement, and facilitates rapid unloading by construction personnel, improving efficiency.

[0032] In step S2, during the process of controlling the upward gantry crane assembly to move laterally along the maximum height H2 to unload material in the first designated unloading area B, it is determined whether the downward gantry crane assembly is within the first designated unloading area B. If so, the upward gantry crane assembly is controlled to move laterally to the outside of the first designated unloading area B and wait; otherwise, the upward gantry crane assembly is controlled to move laterally directly into the first designated unloading area B. Each downward gantry crane assembly is equipped with an RFID tag for positioning. The first RFID reader of the upward gantry crane assembly reads this positioning RFID tag to determine the location information of the upward and downward gantry crane assemblies and sends this information to the control unit. The control unit then completes the above determination. That is, when the first RFID reader reads the positioning RFID tag, it means that the upward and downward gantry crane assemblies are too close. Furthermore, the range of the first RFID reader reading the positioning RFID tag is approximately 10 meters. The reason for allowing only one upward or downward gantry crane assembly to enter the first designated unloading area is to avoid collisions between the two during movement, which could lead to equipment damage or safety accidents.

[0033] S3, after unloading is completed, control the upward gantry crane assembly to leave the first designated unloading area B; then control the downward gantry crane assembly to move laterally along the track assembly 5 to the first designated unloading area B to connect with the material X and transport it to the second designated unloading area C.

[0034] This allows material X to be transferred to the required construction site without manual handling. After further unloading is completed, once the upward gantry crane assembly leaves the first designated unloading area B, the upward gantry crane assembly will repeat steps S1-S2 to repeatedly transfer the ground material X onto the floor slab 2.

[0035] It is worth mentioning that after the downlift gantry assembly is connected to the material X stored in the first designated unloading area B, it will be raised to a predetermined height. This can prevent the material X from rubbing against the floor slab 2 and can avoid most of the debris placed on the floor slab 2.

[0036] Furthermore, based on steps S2-S3, the first designated unloading area B can be divided into multiple first designated unloading areas B according to the type of material X being lifted. These multiple first designated unloading areas B can be set up adjacent to each other, thus reducing the space occupied by the floor slab 2. Similarly, the second designated unloading area C is also divided into multiple second designated unloading areas C according to the type of material X. These multiple second designated unloading areas C can be set up near the current construction location for different types of material X, making it convenient for construction personnel to retrieve material X and reducing their labor intensity.

[0037] To further facilitate the classification of material X, the prefabricated housing intelligent construction platform includes a first RFID reader mounted on the upward gantry crane assembly, the first RFID reader being connected to the control unit; the control method further includes: S11; When material X reaches its maximum height H2, which is the reading range of the first RFID reader, the type information of material X is obtained by reading the RFID tag set on material X through the first RFID reader.

[0038] S21; Then, during the process of controlling the upward gantry crane assembly to move laterally along the track assembly 5 at the maximum height H2 to the first designated unloading area B for unloading, the material X is unloaded into different material X areas of the first designated unloading area B according to its type information.

[0039] This allows the control unit to determine which first designated unloading area B the batch of material X will be delivered to for unloading. In one example, RFID tags can be affixed to the material X by ground workers.

[0040] Furthermore, based on the multiple designated second unloading areas C, the prefabricated residential intelligent construction platform further includes a second RFID reader installed on the descending gantry assembly, the second RFID reader being connected to the control unit; the control method further includes: S13, during the process of controlling the downward gantry crane assembly to move laterally along the track assembly 5 to the first designated unloading area B to connect with material X and transport it to the second designated unloading area C, the second RFID reader reads the RFID tag set on material X to determine whether material X matches the requirement. If it does, it is transported to the second designated unloading area C; otherwise, an alarm is triggered, and staff are reminded to find the required material X. This further confirms that material X is the material X required at the construction site where the second designated unloading area C is located, avoiding the situation of incorrect material X transfer.
