Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated T-beam wing plate reinforcement binding, and in particular to a prefabricated reinforcement binding jig based on an AGV trolley. Background Technology

[0002] With the continuous development of society and economy, bridge engineering construction has developed rapidly. Bridge engineering technology and construction techniques have continuously improved and innovated. Continuous beam bridges, with their advantages of simple structure followed by continuous structure, clear stress distribution, material saving, convenient erection and installation, large span capacity, and simple construction, are widely used in modern bridge construction. In the construction of precast T-beam flanges, the workload of rebar tying is substantial. Although the use of rebar tying platforms for T-beam flanges is currently quite common, different types and sizes of T-beam flange rebar tying jigs still affect the overall tying effect, leading to issues such as uneven rebar alignment and non-standard spacing control, resulting in large construction errors, low efficiency, and low tying quality and rebar protective layer qualification rate.

[0003] Chinese Patent No. CN211221309U discloses a precast T-beam wing plate rebar binding jig assembly, comprising a precast T-beam wing plate rebar binding and positioning jig assembly and a negative moment steel strand toothed plate rebar jig assembly; the top of the first support frame is provided with transverse rebar positioning toothed plates along the length of the concrete foundation; the top of the second support frame is provided with a track along the length of the concrete foundation; multiple longitudinal rebar positioning plates are arranged at equal intervals along the length of the concrete foundation between the two first support frames corresponding to the two concrete foundations, each longitudinal rebar positioning plate having several positioning slots; multiple wing plate transverse rebar limiting plates are arranged at equal intervals along the length of the concrete foundation between the first support frame and the second support frame corresponding to each concrete foundation, each wing plate transverse rebar limiting plate having a limiting slot, the limiting slot being movably connected to the wing plate transverse rebar limiting plate; the T-beam wing plate rebar binding and positioning jig assembly also includes a shear stress positioning rebar trolley, the shear stress positioning rebar trolley being movably fitted on two parallel tracks; the shear stress positioning rebar trolley has several shear rebar positioning plates located on the same straight line.

[0004] The existing technical solutions described above have the following drawbacks: The aforementioned rebar tying frame assembly mainly relies on manual labor to sequentially install the web rebars on the transverse rebar positioning plates, and then thread the main rebars along the longitudinal rebar positioning plates to complete the rebar positioning on the rebar cage. However, manual operation is inefficient and it is difficult to guarantee the accuracy and stability of the rebars. Furthermore, although the shear stress positioning rebar trolley mentioned in this technical solution can assist in the movement and positioning of the rebars to some extent, since the rebars are in a stacked state, manual assistance is still required. Therefore, there are still many inconveniences in practical applications, and improvements are needed. Utility Model Content

[0005] The problem this invention aims to solve is to provide an assembled rebar binding jig based on an AGV (Automated Guided Vehicle) to address the aforementioned shortcomings in the existing technology. This jig has the advantage of improving the efficiency of rebar positioning and installation.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0007] An AGV-based prefabricated rebar binding jig includes a support frame, at least two web rebar positioning teeth plates disposed on the support frame, and multiple main rebar positioning teeth. It also includes a lifting AGV, at least two pre-positioning racks disposed at the output end of the lifting AGV, and multiple lifting and rotating mechanisms mounted on the support frame. The moving path of the lifting AGV passes between two of the web rebar positioning teeth plates, so that the grooves on these web rebar positioning teeth plates and pre-positioning racks are flush and arranged relative to the web rebar of the workpiece. The main rebar positioning teeth are disposed at the output end of the lifting and rotating mechanisms, so that the grooves on the main rebar positioning teeth are arranged relative to the main rebar of the workpiece.

[0008] By adopting the above technical solution, during the actual positioning and installation of the reinforcing cage, after the web reinforcement is pre-installed and welded on the pre-positioning rack of the lifting AGV trolley, a group of neatly arranged web reinforcements are first lifted by the lifting AGV trolley and moved close to the support frame to move the web reinforcements horizontally above one section of the web reinforcement positioning rack. Then, the lifting AGV trolley descends until the grooves on the web reinforcement positioning rack and the pre-positioning rack are aligned. At this point, the group of web reinforcements is inserted and installed on the web reinforcement positioning rack. Then, the lifting AGV trolley continues to descend so that the pre-positioning rack disengages from the web reinforcement and moves horizontally away from the support frame. The support frame is used to position and install a set of web reinforcement bars. This process is repeated multiple times to complete the installation of all web reinforcement bars on the workpiece. Next, the lifting and rotating mechanism drives the main reinforcement positioning toothed rod to unfold and lift, so as to complete the positioning and installation of one layer of main reinforcement bars. This process is repeated at least twice to complete the installation of each layer of main reinforcement bars on the workpiece. During this process, multiple sets of web reinforcement bars are continuously transferred to the web reinforcement positioning toothed plate by the lifting AGV trolley and the main reinforcement positioning toothed rod. With the assistance of the lifting and rotating mechanism and the main reinforcement positioning toothed rod, at least two layers of main reinforcement bars are positioned on the web reinforcement bars. This greatly improves the efficiency of reinforcement bar positioning and installation and ensures the accuracy and stability of the reinforcement cage binding during the process.

[0009] The present invention is further configured to include a travel track, which is arranged along the movement path of the lifting AGV and is configured to cooperate with the wheels of the lifting AGV.

[0010] By adopting the above technical solution and setting up the trolley track, the lifting AGV trolley becomes more stable during movement, avoiding possible swaying or deviation during movement, thereby further ensuring the accuracy of rebar positioning and installation; in addition, the setting up of the trolley track also makes the trolley's movement path clearer, improving overall work efficiency.

[0011] The present invention is further configured to include two sets of horizontal drive cylinders arranged symmetrically on the support frame, and a pair of limiting side plates respectively arranged on the piston rods of the two sets of horizontal drive cylinders, wherein the plate surface of the limiting side plates is arranged relative to the end of the web reinforcement of the workpiece.

[0012] By adopting the above technical solution, the setting of the limiting side plate plays a good limiting role at both ends of the web reinforcement, avoiding the displacement or misalignment of the web reinforcement during installation, thereby further ensuring the accuracy of reinforcement positioning and installation; in addition, by driving the limiting side plate to move through the horizontal drive cylinder, the web reinforcement of workpieces of different sizes can be limited, improving the versatility and practicality of the prefabricated reinforcement binding jig.

[0013] The present invention is further configured such that: two pairs of web reinforcement positioning teeth are provided and are arranged at intervals between the pair of limiting side plates along the length direction of the web reinforcement, and the moving path of the lifting AGV trolley passes between the pair of web reinforcement positioning teeth.

[0014] By adopting the above technical solution, the setting of two pairs of web reinforcement positioning teeth further improves the stability and accuracy of web reinforcement during installation. At the same time, the web reinforcement positioning teeth are arranged at intervals along the length of the web reinforcement, which can realize the positioning and installation of web reinforcement of different lengths, further improving the versatility and practicality of the prefabricated reinforcement binding jig.

[0015] The present invention is further configured such that: two sets of main rib positioning teeth are provided and are respectively installed on the pair of limiting side plates through lifting and rotating mechanisms, and multiple main rib positioning teeth in each set are arranged at intervals along the length direction of the main rib.

[0016] By adopting the above technical solution, the setting of two sets of main reinforcement positioning teeth can simultaneously position and install the main reinforcement on both sides, avoiding positioning errors caused by excessively long and tilted main reinforcement positioning teeth, and further improving the efficiency of reinforcement positioning and installation; at the same time, multiple main reinforcement positioning teeth in each set are arranged at intervals along the length of the main reinforcement, which can realize the positioning and installation of main reinforcement of different lengths, further improving the versatility and practicality of the prefabricated reinforcement binding jig.

[0017] The present invention is further configured such that: the lifting and rotating mechanism includes a lifting rodless cylinder disposed on the limiting side plate and a rotating cylinder disposed at the output end of the lifting rodless cylinder, and the main rib positioning toothed rod is disposed at the output end of the rotating cylinder.

[0018] By adopting the above technical solution, the coordinated setting of the lifting rodless cylinder and the rotary cylinder can realize the lifting and rotating motion of the main reinforcement positioning rack, thereby facilitating the positioning and installation of the main reinforcement; at the same time, both the lifting rodless cylinder and the rotary cylinder have high stability and accuracy, further ensuring the accuracy and stability of the reinforcement positioning and installation.

[0019] The present invention is further configured such that: the support frame and the web reinforcement positioning tooth plate are provided with multiple lifting grooves, and the moving path of the main reinforcement positioning tooth rod passes through the lifting grooves.

[0020] By adopting the above technical solution, the lifting chute provides guidance and limitation for the movement of the main reinforcement positioning rack, ensuring the stability and accuracy of the main reinforcement positioning rack during movement. At the same time, the lifting chute facilitates the lifting and lowering operation of the main reinforcement positioning rack, allowing it to be stored in the lower part of the support frame, further improving the efficiency of reinforcement positioning and installation.

[0021] The present invention is further configured to include a limiting end plate disposed on the support frame, wherein the plate surface of the limiting end plate is arranged relative to the end of the main rib of the workpiece.

[0022] By adopting the above technical solution, the setting of the limiting end plate not only plays a good limiting role on one end of the main reinforcement, but also does not affect the passage of the lifting AGV trolley, thus avoiding the main reinforcement from shifting or misaligning during installation, thereby further ensuring the accuracy of the reinforcement positioning and installation; in addition, the limiting end plate can also limit the installation position of the main reinforcement, making the installation of the main reinforcement more neat and further improving the quality of the reinforcement cage binding.

[0023] In summary, the beneficial technical effects of this utility model are as follows: by using a lifting AGV trolley and a main reinforcement positioning toothed rod to continuously transfer multiple sets of web reinforcement bars on the web reinforcement positioning toothed plate, and by using a lifting and rotating mechanism and a main reinforcement positioning toothed rod to complete the positioning of at least two layers of main reinforcement bars on the web reinforcement bars, the efficiency of reinforcement bar positioning and installation is greatly improved, and the accuracy and stability of reinforcement cage binding during the process are ensured.

[0028] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 This utility model discloses an assembled rebar binding jig based on an AGV (Automated Guided Vehicle) trolley, comprising a support frame 1, two pairs of web rebar positioning teeth 2 mounted on the support frame 1, two sets of main rebar positioning teeth 3, a travel track 4, a lifting AGV trolley 5, at least two pre-positioning racks 6 mounted on the output end of the lifting AGV trolley 5, and two sets of lifting and rotating mechanisms 7 mounted on the support frame 1. The moving path of the lifting AGV trolley 5 passes between the pair of web rebar positioning teeth 2, so that the grooves on these web rebar positioning teeth 2 and the pre-positioning racks 6 are flush and arranged relative to the web rebar of the workpiece; the travel track 4 is arranged along the moving path of the lifting AGV trolley 5 and is configured to cooperate with the wheels of the lifting AGV trolley 5; the main rebar positioning teeth are located at the output end of the lifting and rotating mechanisms, so that the grooves on the main rebar positioning teeth are arranged relative to the main rebar of the workpiece.

[0030] In the actual rebar cage positioning and installation process, after the web rebars are pre-installed and welded on the pre-positioning rack 6 of the lifting AGV trolley 5, a group of neatly arranged web rebars are first lifted by the lifting AGV trolley 5 and moved close to the support frame 1 to move the web rebars horizontally above one section of the web rebar positioning rack 2. Then, the lifting AGV trolley 5 is lowered until the grooves on the web rebar positioning rack 6 and the pre-positioning rack 6 are flush. At this point, the group of web rebars is inserted and installed on the web rebar positioning rack 2. Then, the lifting AGV trolley 5 continues to lower so that the pre-positioning rack 6 is detached from the web rebars and moves horizontally away from the support frame 1. The process involves several steps: first, positioning and installing a set of web reinforcement bars; then, the lifting and rotating mechanism 7 drives the main reinforcement positioning toothed rod 3 to unfold and lift, thus positioning and installing one layer of main reinforcement bars. This process is repeated at least twice to complete the installation of each layer of main reinforcement bars on the workpiece. During this process, the lifting AGV trolley 5 and the main reinforcement positioning toothed rod 3 continuously transfer multiple sets of web reinforcement bars to the web reinforcement positioning toothed plate 2. The lifting and rotating mechanism 7 and the main reinforcement positioning toothed rod 3 are also used to position at least two layers of main reinforcement bars on the web reinforcement bars, thereby greatly improving the efficiency of reinforcement bar positioning and installation and ensuring the accuracy and stability of the reinforcement cage binding during the process.

[0031] Reference Figure 2 To improve the positioning and installation accuracy of the workpiece, the prefabricated rebar binding jig also includes two sets of horizontal drive cylinders 8 arranged symmetrically on the support frame 1, a pair of limiting side plates 9 respectively set on the piston rods of the two sets of horizontal drive cylinders 8, and a limiting end plate 10 set on the support frame 1. Among them, the plate surface of the limiting side plate 9 is arranged relative to the end of the web rebar of the workpiece, and the plate surface of the limiting end plate 10 is arranged relative to the end of the main rebar of the workpiece.

[0032] The limiting side plate 9 effectively limits the two ends of the web reinforcement, preventing displacement or misalignment during installation and further ensuring the accuracy of reinforcement positioning. Furthermore, by moving the limiting side plate 9 via the horizontal drive cylinder 8, the web reinforcement of different sized workpieces can be limited, improving the versatility and practicality of this prefabricated reinforcement binding jig. The limiting end plate 10 effectively limits one end of the main reinforcement without obstructing the passage of the lifting AGV trolley 5, preventing displacement or misalignment during installation and further ensuring the accuracy of reinforcement positioning. In addition, the limiting end plate 10 can also limit the installation position of the main reinforcement, resulting in neater installation and further improving the quality of the reinforcement cage binding.

[0033] Reference Figure 1The two pairs of web reinforcement positioning teeth 2 are arranged at intervals between the two pairs of limiting side plates 9 along the length direction of the web reinforcement, and the two sets of main reinforcement positioning teeth 3 are respectively installed on the two pairs of limiting side plates 9 through the lifting and rotating mechanism 7. Multiple main reinforcement positioning teeth 3 in each set are arranged at intervals between each other along the length direction of the main reinforcement.

[0034] The two pairs of web reinforcement positioning teeth 2 further improve the stability and accuracy of the web reinforcement during installation. Simultaneously, the web reinforcement positioning teeth 2 are arranged at intervals along the length of the web reinforcement, enabling the positioning and installation of web reinforcements of different lengths, further enhancing the versatility and practicality of this prefabricated reinforcement binding jig. The two sets of main reinforcement positioning teeth 3 allow for the simultaneous positioning and installation of the main reinforcements on both sides, avoiding positioning errors caused by excessive length and tilting of the main reinforcement positioning teeth 3, and further improving the efficiency of reinforcement positioning and installation. Furthermore, the multiple main reinforcement positioning teeth 3 in each set are arranged at intervals along the length of the main reinforcement, enabling the positioning and installation of main reinforcements of different lengths, further enhancing the versatility and practicality of this prefabricated reinforcement binding jig.

[0035] Reference Figure 3 The lifting and rotating mechanism 7 includes a lifting rodless cylinder 71 mounted on the limiting side plate 9, and a rotating cylinder 72 mounted on the output end of the lifting rodless cylinder 71. The main reinforcement positioning tooth 3 is mounted on the output end of the rotating cylinder 72. The support frame 1 and the web reinforcement positioning tooth plate 2 are provided with multiple lifting grooves 73, and the movement path of the main reinforcement positioning tooth 3 passes through the lifting grooves 73.

[0036] The coordinated arrangement of the lifting rodless cylinder 71 and the rotary cylinder 72 enables the lifting and rotating motion of the main reinforcement positioning rack 3, facilitating the positioning and installation of the main reinforcement. Simultaneously, both the lifting rodless cylinder 71 and the rotary cylinder 72 possess high stability and accuracy, further ensuring the accuracy and stability of the reinforcement positioning and installation. The lifting slide 73 provides guidance and limitation for the movement of the main reinforcement positioning rack 3, ensuring its stability and accuracy during movement. Furthermore, the lifting slide 73 facilitates the lifting and lowering operation of the main reinforcement positioning rack 3, allowing it to be stored under the support frame 1, further improving the efficiency of reinforcement positioning and installation.
