Description

Technical Field

[0001] This invention belongs to the technical field of automated manufacturing equipment for precast concrete components, and relates to a split-type intelligent mobile platform system for bottom mold and its operation method. Background Technology

[0002] In the field of highway bridge construction, traditional precast beam yards generally adopt a fixed formwork platform model for beam fabrication. Precast beams undergo all processes, including pouring, curing, and tensioning, on these fixed platforms before being lifted and transported by gantry cranes. Smart beam factories, by transforming fixed precast beam platforms into mobile platforms, have to some extent achieved a production line operation mode, significantly improving production efficiency, but still suffer from low automation. Furthermore, because precast concrete beams are large, easily deformable materials with small deformation tolerances, their deformation deviations must be strictly controlled during platform movement to avoid structural damage caused by localized stress concentration.

[0003] To address the need for automation upgrades in the transportation of precast concrete small box girders, existing patents have demonstrated partial technological breakthroughs: Patent CN118701121A discloses a precast small box girder transport trolley with a centering correction mechanism, enabling real-time correction of tilt deviations of precast beams after hoisting and placement, significantly improving operational efficiency and transportation stability; Patent CN219467736U achieves automated transport in the beam storage area through modular combination of the precast beam transport trolley frame, effectively reducing gantry crane occupancy and eliminating the risk of track intersection operations; Patent CN215322203U designs a special flatcar with an anti-tipping structure for transporting untensioned precast small box girders, achieving automated transport of untensioned precast small box girders and reducing the need for human resource allocation.

[0004] However, the aforementioned inventions only focus on solving some technical details in the transfer process of precast beams, and none of them have achieved automated production and full-domain collaborative management of precast beams throughout the entire production line. Existing integrated bottom formwork mobile platforms still suffer from pain points such as discontinuous power supply, long occupation time of the platform at the workstation, significant impact of the platform motor on the high temperature and humidity steam curing environment, and reliance on manual scheduling of the platform between workstations. These issues severely restrict the goal of achieving intelligent construction with full automation of the precast beam production process. Summary of the Invention

[0005] This invention aims to remove bottlenecks in the automation of the entire precast beam production process, solve problems such as the damage to the durability of the test bench motor and controller due to long-term exposure to high temperature and humidity, and truly realize a fully automated production management and data management model for smart beam factories.

[0006] To achieve the above objectives, the present invention provides a split-type intelligent mobile platform system for bottom molds, comprising:

[0007] The non-powered bottom formwork platform includes a bottom formwork, a platform frame, and a platform support. The bottom formwork is set on the top of the bottom formwork platform, and a hydraulic lifting force point is set at the bottom of the bottom formwork platform.

[0008] A mobile intelligent platform trolley includes a lifting cylinder, front drive wheels, rear drive wheels, a front hydraulic station, a rear hydraulic station, a power battery pack, a high-voltage distribution box, a low-voltage distribution box, and a control system. The lifting cylinder is used to lift and lower the bottom mold platform. The front and rear drive wheels work together to move the trolley. The front and rear hydraulic stations provide power to the lifting cylinder. The power battery pack supplies power to the entire trolley. The high-voltage and low-voltage distribution boxes are responsible for power distribution. The control system enables wireless communication and overall control. The control system includes a high-voltage control system and a low-voltage control system.

[0009] The intelligent platform trolley and the bottom mold base are physically separate structures;

[0010] The bottom formwork platform is used to support the precast beam and moves with the precast beam through various processes. It does not have power or electricity. The intelligent trolley can lift and transport the bottom formwork platform, realizing the fully automated flow of the precast beam production process.

[0011] Furthermore, the lifting cylinder adopts a proportional valve for precise control and a group-coordinated lifting mode to achieve a synchronous lifting error of less than 2mm.

[0012] Furthermore, the control system includes a high-voltage control system and a low-voltage control system. The high-voltage control system is powered by a 48V-400Ah lithium battery pack to power the drive motor and pump station. The low-voltage control system is powered by 24V to ensure the operation of the controller and sensors. The control system also includes a 380V AC interface and an inverter circuit.

[0013] Furthermore, the front hydraulic station and the rear hydraulic station are respectively arranged at the front and rear ends of the trolley, and the oil circuit is equipped with a two-way balance valve.

[0014] On the other hand, the present invention also provides an operating method based on the above system, comprising the following steps:

[0015] (1) The intelligent platform trolley moves to the bottom of the bottom mold base, lifts the bottom mold base to a certain height and then transfers it to the cloth position. Then the platform descends so that the bottom mold base falls on the support seat and the trolley returns to the initial position.

[0016] (2) After the template is automatically installed, the material is laid. After vibration, initial setting, precast beam forming and demolding, the intelligent platform trolley travels to the designated position, lifts the bottom formwork platform and precast beam to a certain height and transfers them to the steam curing station. The bottom formwork platform is placed on the support position to start steam curing, and the trolley returns to the initial position.

[0017] (3) After steam curing is completed, the intelligent trolley will transfer the bottom formwork base and precast beam to the standard curing station for curing, and then the trolley will return to the initial position.

[0018] (4) After standard curing is completed, the intelligent platform trolley will transfer the bottom formwork and precast beam to the tensioning station to complete the tensioning operation;

[0019] (5) After tensioning is completed, the intelligent trolley and the bottom formwork pedestal are moved laterally to the return track via the rail-guided vehicle (RGV) trolley, and then moved back to the initial position via the return track and the RGV trolley to complete one operation.

[0020] Furthermore, in steps (3) and (4), the transfer between the steam curing chamber and the standard curing chamber is wirelessly triggered by the central controller, and the lifting height remains constant.

[0021] Furthermore, the return line auxiliary track is parallel to the production line track, and the RGV traverse trolley and the intelligent bench trolley are coupled and transferred to the bottom mold through positioning pins.

[0022] Furthermore, the intelligent platform trolley automatically switches between shuttle mode, connection mode, and workstation placement mode, without requiring manual intervention throughout the entire process.

[0023] Furthermore, the intelligent trolley has three tooling states during the transfer process: when transferring between workstations, the bottom mold base is supported on the trolley frame; when the workstations are connected, the hydraulic cylinder lifts the bottom mold base to the track support surface; when the work operation point is in place, the hydraulic cylinder lowers so that the bottom mold base rests on the support surface and the trolley drives away.

[0024] This invention also provides a smart beam factory system, comprising:

[0025] Such as the intelligent benchtop vehicle mentioned above;

[0026] Multiple production lines, each equipped with 4 bottom mold bases;

[0027] Transverse tracks and bottom mold return tracks are arranged in the fabrication area and tensioning area;

[0028] The central control console dispatches trolleys to work across production lines via a wireless network.

[0029] The beneficial effects of this invention are:

[0030] (1) The bottom mold split intelligent mobile platform system combines the structural advantages, track gauge, and running wheels of the existing mobile bottom mold platform. It adopts a split structure design of bottom mold platform and platform, realizing the intensive operation of multiple bottom molds on one or more production lines by adapting a single platform trolley, which significantly reduces equipment investment and overall energy consumption.

[0031] (2) By adding a modular system architecture such as a vehicle control system, a hydraulic lifting system and a battery management system, the precast beams can be automatically and accurately transported across the entire process to improve equipment operating efficiency and the convenience of manual operation.

[0032] (3) By optimizing the layout of hydraulic pipelines and valve group configuration, the hydraulic cylinders are grouped for lifting and coordinated control, ensuring that the off-center load during multi-cylinder coordinated lifting operations is less than 2mm, thereby improving the deviation control accuracy and safety reliability during the transfer of precast beams.

[0033] (4) The bottom mold split intelligent mobile platform system replaces the traditional wired power supply with lithium battery power supply. It is combined with the electrical control system, integrates AC / DC dynamic conversion mechanism, high and low voltage regulation function and other modules, and realizes remote status monitoring and command control based on wireless communication. It effectively solves the problems of low efficiency and safety hazards caused by manual dragging of cables and frequent plugging and unplugging of interfaces. Attached Figure Description

[0046] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0047] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, components with the same structure or function are shown only schematically, or only one is labeled.

[0048] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, etc.) used to explain the structure and movement of the various components of the invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0049] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, without creative effort, they can obtain drawings of other similar structural products and other implementation methods based on these drawings.

[0050] To achieve automated transfer of large precast concrete components between various production processes on the production line, this embodiment discloses a split-type intelligent mobile platform system for the bottom mold, and proposes a beam factory operation process adapted to this system. For example... Figure 1 As shown, the intelligent trolley system separates the traditional integral mobile mold base into a mold base 2 and an intelligent trolley 1, with the intelligent trolley mounted on a trolley track 3. Among these components, as shown... Figure 2 As shown, the bottom formwork platform consists of a stainless steel bottom template 4 and a lower steel platform frame 5. Several platform support structures 6 are also provided at both ends of the platform frame 5. One bottom formwork platform is required in each work area to support the precast beams working on it and to facilitate their movement between different processes. The bottom formwork platform is not powered; its movement is accomplished by an intelligent platform trolley. A hydraulic cylinder lifting point is provided at the bottom to accept the lifting action of the hydraulic cylinders on the intelligent platform trolley. Figure 3 As shown, the track of the trolley is the same as that of a traditional mobile platform, including the trolley track base plate 7, the template support seat 8, and the bottom formwork support columns 9 distributed on both sides of the track. A schematic diagram of the intelligent trolley is shown below. Figure 4As shown, the system includes a lifting cylinder, front drive wheels, rear drive wheels, a front hydraulic station, a rear hydraulic station, a power battery pack, a high-voltage distribution box, a low-voltage distribution box, and a control system. The lifting cylinder is used to raise and lower the bottom mold platform. The front and rear drive wheels work together to move the trolley. The front and rear hydraulic stations provide power to the lifting cylinder. The power battery pack supplies power to the entire trolley. The high-voltage and low-voltage distribution boxes are responsible for power distribution. The control system enables wireless communication and overall control. The trolley is powered by lithium batteries located at the bottom of the frame. Multiple sets of hydraulic cylinder lifting devices are configured between the trolley frames to lift the bottom mold platform to a certain height. The intelligent trolley, equipped with intelligent sensors and a PLC control system, can upload sensing data in real time and receive control commands from the control platform, enabling intelligent production scheduling. The biggest advantage of separating the intelligent trolley from the bottom formwork base is that the trolley only needs to undertake the transportation function and no longer serves as the main load-bearing component at the workstation. This allows the trolley to move freely between workstations, thereby connecting all production processes of precast beams and realizing fully automated flow of precast beam production processes.

[0051] To adapt to the intelligent formwork trolley system, the existing layout of the smart beam factory and the precast beam manufacturing process will be partially adjusted. The production process adapted to the intelligent split-type formwork trolley is as follows: each production line is equipped with four bottom formwork pedestals. When stationary, the top of the bottom formwork pedestal supports the precast component, while the main body rests on support legs on both sides of the track. Each section or production line in the beam factory only needs one intelligent formwork trolley. During transport, the trolley lifts the bottom formwork pedestal and moves it to the concrete pouring position, then lowers the pedestal and leaves the current position. The side formwork and bottom formwork then begin to assemble. The intelligent formwork trolley can return to its initial position or continue forward into the elevated steam curing chamber. The cured precast beam, along with the bottom formwork pedestal, is lifted and transferred to the standard curing chamber. After curing, it is transferred to the precast beam tensioning position. The intelligent formwork trolley can move freely on the production line track and also on the return track. It is worth noting that since the bottom mold flows unidirectionally with the beam during the beam manufacturing process, a return track is required when the bottom mold returns. The return of the bottom mold and the replacement of the intelligent bench trolley on the production line can both be completed by synchronous movement of the RGV trolley.

[0052] The intelligent bench trolley exhibits three tooling states during the lifting process at each workstation: when the intelligent bench trolley is moving between workstations, such as... Figure 5 As shown, the bottom mold platform is lifted onto the trolley by a hydraulic cylinder. The trolley moves along a preset track to transfer the precast component to the next workstation. When the intelligent trolley is in the workstation transition state (entry preparation or departure), as... Figure 6 As shown, under load, the hydraulic cylinder lifts the bottom mold platform to a certain height, ensuring its stable location on both sides of the track support surface. Based on this requirement, the anti-eccentric load capability of the hydraulic cylinder must be a key acceptance indicator for the hydraulic system design. When the intelligent platform trolley is located at the process operation point, such as... Figure 7 As shown, the hydraulic cylinder load lowers and places the bottom mold base on the support surfaces on both sides of the track. The trolley can move forward or back to its original position along the preset track without having to stay or wait in the work area.

[0053] This embodiment also provides the overall design concept of the above system, including the following steps:

[0054] 1. Mechanical structure design

[0055] The 3D model design of the intelligent trolley system was completed using mechanical design tools. This system inherits the structural advantages, track gauge, and wheel characteristics of the existing mobile formwork platform in the beam factory, and innovatively adopts a separate structure for the formwork and mobile platform to complete the handling operations. The intelligent trolley system consists of modules such as the trolley track and track base plate, the formwork platform, and the intelligent trolley and formwork platform supports. The formwork platform is welded from a stainless steel base plate and a steel frame. The bottom width of the formwork platform must be greater than the distance between the support legs on both sides of the track, and a hydraulic cylinder lifting force point is preset at the bottom to accept the lifting action of the hydraulic cylinders on the intelligent trolley. The intelligent trolley, through the addition of a modular system architecture including a vehicle control system, a hydraulic lifting system, and a battery power distribution system, completes intelligent production scheduling operations across production lines. The rated load capacity of the trolley is comprehensively calculated based on the project's product requirements. Simultaneously, multi-scheme simulation analysis was conducted based on the 3D model to design the optimal configuration as needed and optimize the selection of component materials. While ensuring structural safety and reliability, refined control of steel usage was implemented. Finally, through finite element analysis of the system architecture, topology reinforcement was carried out on key modules based on stress distribution.

[0056] 2. Hydraulic Lifting System Design

[0057] This system employs a dual hydraulic station configuration to ensure balanced oil flow to the hydraulic cylinders at both ends of the trolley. Combined with precise proportional valve control and group-coordinated lifting modes, it achieves a synchronous lifting error of less than 2mm across all seven hydraulic cylinders, performing lifting operations at a constant rate of 5mm / second. This minimizes the eccentric stress and lifting angle on the beam during lifting, significantly improving the stability and structural safety of the lifting motion of large precast components. The hydraulic lifting system schematic is shown in Figure 8. The top section is a hydraulic control unit integrating filtration and pressure regulation functions, including pumps, valves, and filters, used to regulate the pressure, flow, and cleanliness of the hydraulic oil. Below, multiple similarly structured actuators are connected via pipelines. Each actuator consists of multiple hydraulic valve groups and hydraulic cylinders. These actuators, driven by hydraulic oil, perform extension and retraction actions according to system settings, achieving functions such as trolley lifting. The overall system presents a top-down hydraulic control and execution hierarchy, ensuring the orderly distribution and execution of hydraulic power. The system's lifting load capacity and height should be customized according to the beam manufacturer's product specifications and equipment parameters.

[0058] 3. Electrical Control System Design

[0059] The electrical control system comprises two parts: a high-voltage control system and a low-voltage control system. It integrates AC / DC dynamic conversion and real-time high / low voltage regulation modules, and utilizes wireless communication to achieve remote status monitoring and command control of the intelligent test bench vehicle. The high-voltage control system houses four 48V-400Ah lithium battery packs to power the front and rear drive motors and pump station. The low-voltage control system uses 24V power to ensure the stable operation of the vehicle controller, data sensors, and other equipment. Since the intelligent test bench vehicle is powered by lithium batteries, the control system must include a dedicated 380V AC interface and inverter circuit to ensure safe and reliable charging and discharging processes. The electrical control system logic diagram is shown below. Figure 9 As shown, this diagram illustrates the electrical power distribution and control system architecture of the test bench vehicle. The system power supply includes a 24V battery and 380V AC mains power: the 24V battery, via a low-voltage distribution box, powers the low-voltage pump station, various sensors, and all types of lights, and also supplies power to the vehicle controller and BMS (Battery Management System) via DC / DC conversion; the 380V AC mains power, after AC / DC conversion, is connected to the high-voltage distribution box, which connects to four battery packs. Its output, via DC / AC conversion, powers the front and rear drive motors and the pump station, and also participates in the high-voltage side power distribution of the vehicle. The BMS, in conjunction with the vehicle controller, manages and controls the battery and the vehicle's electrical system, ensuring the rational allocation and stable operation of the equipment's power.

[0060] 4. Production line layout and manufacturing process flow

[0061] Each production line in the intelligent beam factory is equipped with four bottom formwork platforms, located in the four workstations of material placement, steam curing, standard curing, and tensioning, respectively. Their travel tracks use the 900mm gauge of traditional moving platforms. Given that the bottom formwork platforms move unidirectionally with the beam during the beam fabrication process, and that the intelligent platform trolley needs to adapt to the coordinated scheduling requirements of multiple production lines in a single work area under ideal conditions, the design should include multiple traverse tracks and bottom formwork return tracks within the production area as needed. The return transfer of the bottom formwork and the switching of the intelligent platform trolley between production lines can be completed synchronously using RGVs (rail-guided vehicles). Taking the Wutianxi Intelligent Beam Factory as an example, it sets up two traverse tracks before the material placement area and after the tensioning area, and plans bottom formwork return tracks during production line intervals, thereby achieving efficient circulation of the bottom formwork platforms and flexible production line scheduling. Based on this layout, the intelligent bench trolley can move freely along the production line and return track, and can also achieve cross-line scheduling via the traverse track. The workflow of the intelligent bench trolley on a single production line is as follows: Figure 10As shown in the flowchart, this process illustrates how the intelligent formwork trolley completes one precast beam production operation. Specifically, the process begins with the intelligent formwork trolley moving to the bottom of the formwork platform, lifting the platform, and transferring it to the material placement position. After the platform descends to the support seat, the trolley returns to its initial position. Next, the formwork is automatically installed, and the material is placed. Through processes such as vibration, the precast beam is formed and demolded. The trolley travels to a designated position, lifts and transfers the formwork platform and precast beam to the steam curing station, and after curing at the support position, the trolley returns to its initial position. It is then transferred to the standard curing station for further curing, and the trolley returns to its initial position again. Afterward, it is transferred to the tensioning station. After tensioning, the RGV trolley moves laterally to the return track, and then returns to its initial position via the return track and the RGV trolley, ultimately completing one operation.

[0062] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
