Description

Technical Field

[0001] This utility model relates to the field of bridge construction engineering, and in particular to an intelligent binding frame for precast box girders in a smart beam yard. Background Technology

[0002] In highway bridge construction, precast box girders are commonly used for erection. Traditional box girder construction presents several inconveniences: First, the completed steel reinforcement cage needs to be lifted and transferred to the pouring area using gantry cranes. This process is not only cumbersome but also requires multiple gantry cranes working together due to the typically long length of the box girder cage, increasing equipment costs and posing safety hazards during lifting. Second, existing binding jigs lack effective coordination with the transportation equipment in the pouring area, leading to poor workflow. Although the trolleys used during pouring have good transportation capabilities, existing binding jigs cannot effectively coordinate with the tracks of the intelligent beam yard's mobile trolleys, resulting in inefficient transportation links in the construction process. Furthermore, traditional jigs lack adjustable support structures during steel reinforcement binding and formwork installation, making it difficult to adapt to the construction needs of box girders of different sizes, severely impacting construction quality and efficiency. These problems are particularly prominent in large-scale bridge construction projects, necessitating the development of a precast box girder binding jig system with multi-directional adjustment capabilities that can work collaboratively with the intelligent beam yard's mobile trolley system. To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0003] To solve the above problems, the technical solution of this utility model is: a smart beam yard precast box girder intelligent binding frame, which includes a base, a trolley track fixedly installed on the base, a trolley that can move on the trolley track, and a box girder binding area and a box girder casting area arranged along both sides of the trolley track. The box girder binding area includes jacking devices symmetrically arranged on both sides of the trolley track. A fixed plate is fixedly installed on the jacking device, and a movable plate is provided on the fixed plate. A horizontal drive device is provided on the fixed plate to drive the movable plate to move horizontally on the fixed plate. A jig side seat is fixedly installed at one adjacent end of the two movable plates, and a movable plate is hinged to one adjacent end of the two fixed plates.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0015] In existing technologies, precast box girder erection is commonly used in highway bridge construction. In traditional processes, after the box girder reinforcement cage is tied, it needs to be transported to the pouring area using gantry cranes, resulting in complex transfer procedures and difficulties in equipment coordination. Due to the large length of the box girders, some scenarios require the coordinated operation of two gantry cranes, limiting construction efficiency. The trolley, a commonly used transportation device in the pouring area, has failed to coordinate with the tying process, causing a disconnect between the two processes.

[0016] To address the aforementioned issues and the pain point of separating the binding and pouring processes, designers discovered the potential of the trolley track to connect the work areas. By studying the track's transport characteristics, a concept was proposed to arrange the binding and pouring areas along both sides of the track. Further analysis revealed that the existing jig fixing structure obstructs trolley passage, necessitating the development of an adjustable binding platform. Based on this, a solution was conceived that utilizes a lifting device to construct a liftable work platform, combined with a horizontal movement mechanism to adjust the jig width, and a tilting structure to overcome trolley passage obstacles.

[0017] exist Figure 1 and Figure 2 Among them, a smart beam yard precast box girder intelligent binding frame is composed of a base 1, a trolley track 13 fixedly installed on the base 1, and a trolley 14 that can move on the trolley track 13. The feature is that a box girder binding area and a box girder casting area are provided on both sides of the trolley track 13. The box girder binding area includes jacking devices symmetrically arranged on both sides of the trolley track 13. A fixed plate 9 is fixedly installed on the jacking device. A movable plate 8 is provided on the fixed plate 9. A horizontal drive device is provided on the fixed plate 9 to drive the movable plate 8 to move horizontally on the fixed plate 9. A jig side seat 11 is fixedly installed at one adjacent end of the two movable plates 18. A movable plate 5 is hinged to one adjacent end of the two fixed plates 9. A flipping drive device is provided at the bottom of the movable plate 5 to drive it to flip.

[0018] The trolley track connects the box girder binding area and the box girder casting area to form a transportation channel, and the bound steel reinforcement cage is directly transferred via trolley 14. After the lifting device is activated, it drives the fixed plate 9 to rise and fall, keeping the binding platform flush with the trolley's bearing surface. The horizontal drive device pushes the moving plate 8 to move laterally, causing the jig side seats 11 to adjust their spacing to adapt to the binding requirements of different box girder sizes. During the binding operation, the movable plate 5 remains horizontal, forming a closed working surface together with the jig side seats; during transfer, the tilting drive device drives the movable plate to tilt downwards, providing clearance for the trolley 14 to pass. The jig side seats 11 can be retracted laterally under the action of the moving plate 8, releasing space for the trolley to pass. Through the coordinated control of the three sets of actions—lifting, horizontal movement, and tilting—dynamic adaptation between the binding platform and the transportation channel is achieved.

[0019] Through the above technical solutions, this application achieves an organic spatial connection between the box girder binding and pouring processes, eliminating the need for overhead cranes. The bound steel reinforcement cage can be directly transported to the pouring area via a trolley, reducing equipment waiting time. The coordinated design of the rotating movable plate 5 and the retracting moving plate 8 ensures unobstructed transport channels while maintaining the functional integrity of the binding platform. The combined application of the lifting device and the horizontal drive device allows the jig to quickly adapt to the construction needs of box girders of different specifications, improving equipment versatility. In traditional processes, the binding platform cannot avoid transport channels; this solution utilizes a dynamic avoidance mechanism formed by the rotating movable plate 5 and the retracting moving plate 8 to achieve spatial reuse for binding and transport.

[0020] This application further proposes a lifting device including a lifting cylinder 2, the bottom of which is fixedly mounted on a base 1, and the other end is fixedly connected to a base 6, which is fixedly connected to a fixing plate 9.

[0021] Through the above technical solutions, this application achieves precise vertical control of the tying frame height, with an adjustment accuracy down to the millimeter level, adaptable to the tying requirements of box girder reinforcement cages with different cross-sectional heights. The rigid connection structure between the lifting cylinder 2 and the base 1 effectively suppresses vibration deviation during operation, ensuring that the positioning accuracy error of the reinforcement is less than 2 millimeters. The rigid force transmission design of the base 6 and the fixing plate 9 ensures uniform load distribution, reducing local stress values ​​to below 60% of the material's allowable stress, significantly improving structural reliability. Furthermore, the support force can be monitored in real time by setting a pressure sensor, avoiding the risk of deformation due to overload.

[0022] This application further proposes a horizontal driving device including a horizontal hydraulic cylinder 7 fixedly mounted on a fixed plate 9, the other end of the horizontal hydraulic cylinder 7 being connected to a movable plate 8, the horizontal hydraulic cylinder 7 being able to drive the movable plate 8 to move horizontally on the fixed plate 9, the upper surface of the fixed plate 9 being provided with a sliding groove, and the lower surface of the movable plate 8 being provided with a boss that cooperates with the sliding groove.

[0023] Through the above technical solution, this application can quickly adapt to the binding requirements of box girders of different specifications, avoiding the tedious operation of repeatedly disassembling the jig or calling on gantry cranes for position adjustment. The sliding fit structure between the moving plate 8 and the fixed plate 9 ensures the stability of the adjustment process, and the linear driving force provided by the horizontal cylinder 7 can effectively overcome the frictional resistance generated by the self-weight of the steel reinforcement cage, ensuring the positioning accuracy of the jig side seat. The upper surface of the fixed plate 9 is provided with a sliding groove, and the lower surface of the moving plate 8 is provided with a boss that cooperates with the sliding groove, which can ensure that the moving plate 8 moves linearly on the fixed plate 9 and avoid deviation.

[0024] This application further proposes that the tilting drive device includes a tilting cylinder 4, which is fixedly mounted on a cylinder seat 3, which is fixedly mounted on a base 6, and the other end of the tilting cylinder 4 is hinged to a movable plate 5.

[0025] Through the above technical solutions, this application can effectively improve the driving stability of the movable plate 5 during the flipping process and ensure the accuracy of the flipping angle control. The rigid fixing design of the cylinder seat 3 and the base 6 reduces the vibration impact of the flipping cylinder 4 during operation and avoids action deviation caused by loose installation. The hinged connection method further optimizes the driving force transmission path, making the flipping action of the movable plate 5 more stable and reliable, and reducing the risk of jamming caused by motion interference.

[0026] This application further proposes that a guardrail 10 is fixedly installed on the side of the movable plate 8 away from the trolley track 13, and a working area is left between the guardrail 10 and the side seat 11 of the jig frame.

[0027] Through the above technical solution, this application effectively prevents the risk of workers falling from the edge of the movable plate 8, ensures that the rebar tying operation has sufficient and independent working space, and avoids collisions between tools or materials and the side seat 11 of the jig during construction.

[0028] This application further proposes that a sleeve 12 is fixedly installed on the side seat 11 of the tire frame.

[0029] Through the above technical solutions, this application achieves standardized positioning of the rebar tying process, reduces manual intervention, and improves tying efficiency and accuracy. At the same time, the rebar skeleton structure formed by the sleeve 12 can be matched with the transportation path of the trolley 14 and the casting mold in terms of size, avoiding docking difficulties caused by structural deformation during transportation, thereby improving the overall construction efficiency.

[0030] This application further proposes that the lifting device, the horizontal drive device, and the tilting drive device are all connected to the control device, and the control device is equipped with a remote control.

[0031] Through the above technical solution, this application achieves centralized control of multiple drive devices, eliminating positioning errors caused by asynchronous manual operation. Remote control operation allows operators to adjust the jig shape from a safe area, avoiding the safety hazards of close-range operation of hydraulic equipment. The optimized timing of actions by the control device avoids system pressure instability caused by simultaneous operation of multiple cylinders, ensuring the smoothness of the jig adjustment process.

[0032] When tying the reinforcing steel cage, the lifting cylinder 2 is raised, the tilting cylinder 4 controls the movable plate 5 to tilt to the horizontal, and the horizontal cylinder 7 controls the two moving plates 8 to move towards each other. At this time, the reinforcing steel cage can be tied as needed.

[0033] After the reinforcement cage is tied, it forms a single structure. The tilting cylinder 4 is controlled to tilt downwards, creating a passage for the trolley 14 to enter the box girder tying area. Once the trolley 14 enters, the lifting cylinder 2 is controlled to descend. When the bottom of the reinforcement cage contacts the trolley 14, the horizontal cylinder 7 is controlled to retract, and the two moving plates 8 move in opposite directions, allowing the reinforcement cage to fall completely onto the trolley and disengage from the moving plates 8. At this point, the trolley 14 can transport the reinforcement cage to the box girder pouring area for pouring.

[0034] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
