Description

Technical Field

[0001] This invention belongs to the field of building industrialization technology, specifically relating to a production and storage mechanism and method for precast highway beam wire. Background Technology

[0002] As the core skeleton of precast beams, the steel cage structure is typically composed of multiple three-in-one stirrups (U-shaped stirrups) arranged at specific process intervals, and formed into a stable whole through longitudinal reinforcement bars inserted at the bottom and sides. In actual production, the longitudinal reinforcement materials can be divided into two categories according to their specifications and preparation methods: one is the wire longitudinal reinforcement group arranged on both sides of the steel cage, which is composed of wire rods; the other is the bar longitudinal reinforcement group arranged at the bottom of the steel cage, which is composed of butt-welded bars.

[0003] In the process of inserting longitudinal ribs into the bottom and sides of the stirrups, it is usually done one by one in sequence. However, whether it is a wire longitudinal rib group or a bar longitudinal rib group, each finished product has the characteristics of large length and high self-weight. When multiple longitudinal ribs need to be installed at the same time, the materials are very prone to mutual interference. For example, the stored longitudinal ribs are squeezed and stacked together, which not only increases the difficulty of classification and positioning, but also seriously affects the work efficiency, becoming the main bottleneck restricting the overall efficiency improvement of the production line.

[0004] Therefore, how to orderly transfer, arrange and store the longitudinal reinforcement bars processed by upstream equipment in accordance with process requirements is a key challenge to achieve efficient and automated production of precast beam reinforcement cages. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned problems existing in the prior art and provides a production and storage mechanism and method for precast highway beam wire rods, so as to realize the automated storage, orderly transfer and regular arrangement of longitudinal reinforcement, thereby improving production efficiency and reducing reliance on manual labor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention proposes a precast highway beam wire production and storage mechanism, including a wire longitudinal reinforcement silo and a finished product support silo. The wire rod longitudinal rib hopper is used to receive and temporarily store the wire rod longitudinal ribs output by the upstream straightening machine; the wire rod longitudinal rib hopper includes multiple racks arranged sequentially along the longitudinal rib conveying direction, each rack is provided with a first-level hopper and a second-level hopper arranged sequentially along the transverse direction of the wire rod longitudinal rib, and a longitudinal rib transfer mechanism for transferring the wire rod longitudinal ribs from the first-level hopper to the second-level hopper. The finished product support silo is located laterally downstream of the wire rod longitudinal reinforcement silo and is used to receive and temporarily store the wire rod longitudinal reinforcement transferred from the wire rod longitudinal reinforcement silo. The finished product support silo includes multiple sets of fixed support units and multiple sets of lifting support units. The lifting support units can be raised and lowered relative to the fixed support units to cooperate with the movement of the wire rod longitudinal reinforcement silo.

[0007] Furthermore, the material rack includes multiple crossbeams spaced apart along the longitudinal rib conveying direction. Each crossbeam is inclined downward toward the finished product support hopper. The crossbeam is provided with spaced upper columns, middle columns and lower columns along its inclined direction, thereby dividing the area above the crossbeam into a first-level hopper and a second-level hopper distributed sequentially along the inclined direction of the crossbeam. The material rack is provided with a material guide downstream of the corresponding wire longitudinal rib hopper, which is used to guide the wire longitudinal rib of the second-level hopper to the finished product support hopper.

[0008] Furthermore, the longitudinal rib transfer mechanism includes a top plate and a first cylinder assembly for the longitudinal rib hopper; the top plate is disposed on one side of the crossbeam and is vertically movable with the material rack; the upper surface of the top plate is a stepped surface that slopes downward toward the finished product support hopper; the stepped surface includes a first-level top plate and a second-level top plate that climb step by step; the first-level top plate extends from the first-level hopper to the second-level hopper; the second-level top plate extends from the second-level hopper to the material guide; the first cylinder assembly for the longitudinal rib hopper drives the top plate to rise and fall, so that the first-level top plate is periodically higher than the middle column, and the second-level top plate is periodically higher than the lower column.

[0009] Furthermore, the material guide includes a movable guide group, which includes a rotating shaft, a material guide rod rotation drive mechanism, and multiple movable material guide rods arranged sequentially along the longitudinal rib conveying direction; the rotating shaft is rotatably mounted on the material rack; the movable material guide rods are fixed on the rotating shaft, and the material guide rod rotation drive mechanism is mounted on the material rack and connected to the rotating shaft, driving the rotating shaft to rotate so that the movable material guide rods on the rotating shaft can be inclined and overlapped on the finished product support hopper or vertically away from the finished product support hopper.

[0010] Furthermore, the material feeder rotation drive mechanism includes a gear, a rack, and a second cylinder assembly for the longitudinal rib hopper; the gear is fixed on the rotating shaft and meshes with the rack; the piston rod of the second cylinder assembly for the longitudinal rib hopper is connected to the rack and drives the rack to move linearly, thereby driving the gear and the rotating shaft to rotate, so as to realize the switching of the movable material feeder between the inclined state and the vertical state.

[0011] Furthermore, the material guide includes a fixed guide group, which includes a plurality of fixed material guide rods arranged sequentially along the longitudinal rib conveying direction; the fixed material guide rods are inclined downward toward the finished product support hopper, one end of the fixed material guide rod is fixed to the material rack, and the other end overlaps the finished product support hopper.

[0012] Furthermore, the plurality of material racks arranged sequentially along the longitudinal rib conveying direction include a first wire longitudinal rib material rack, a second wire longitudinal rib material rack, a third wire longitudinal rib material rack, and a fourth wire longitudinal rib material rack; the first wire longitudinal rib material rack is located at the end furthest from the upstream straightener, and the fourth wire longitudinal rib material rack is located at the end closest to the straightener; the first wire longitudinal rib material rack is provided with the movable guide group; the second wire longitudinal rib material rack is provided with the movable guide group and / or the fixed guide group; the third and fourth wire longitudinal rib material racks are provided with the fixed guide group.

[0013] Furthermore, the fixed support unit includes a support frame and a material-supporting roller and a material-pushing guide mounted on the support frame; the lifting support unit includes a fixed base, a movable support that slides vertically with the fixed base, and a second cylinder group for driving the movable support to lift; the movable support is equipped with a material-supporting roller and a material-pushing guide; the material-pushing guide is used to push the wire longitudinal ribs temporarily stored on the material-supporting roller to one end away from the wire longitudinal rib hopper, so that they are neatly arranged.

[0014] Furthermore, the material pushing guide includes a pushing rod, a first cylinder assembly supporting the material bin, and a longitudinal rib side limiter; the longitudinal rib side limiter is disposed on the support fixed frame or movable support at the end of the material support roller away from the wire longitudinal rib material bin; the pushing rod is disposed on one side of the material support roller, the end of the pushing rod away from the wire longitudinal rib material bin is rotatably connected to the support fixed frame or movable support through a pushing rod connecting shaft, and the end of the pushing rod near the wire longitudinal rib material bin is connected to the piston rod of the first cylinder assembly supporting the material bin; the first cylinder assembly supporting the material bin drives the pushing rod to rotate around the pushing rod connecting shaft, so that the local upper surface of the pushing rod is periodically higher than the material support roller and remains in an inclined state.

[0015] Furthermore, a feed rod limiting seat is provided on the side of the support fixing frame and / or the movable support near the wire longitudinal rib hopper, and a limiting groove is provided on the feed rod limiting seat. One end of the fixed feed rod or the movable feed rod of the feed guide rests in the limiting groove.

[0016] Furthermore, the upper end face of the push rod includes an arched surface, a concave surface, a flat surface, and an upward surface arranged sequentially toward the longitudinal reinforcing bar hopper; the arched surface is located above the push rod connecting shaft.

[0017] Secondly, the present invention also proposes a method for producing and storing precast highway beam wire, the method being implemented based on the aforementioned precast highway beam wire production and storage mechanism; the method includes the following steps: Step S1: The upstream straightening machine straightens and cuts the wire rod. The cut wire rod longitudinal bars fall into the first-level bins of each rack of the wire rod longitudinal bar bin through the guide device. Step S2: When the number of wire longitudinal ribs falling into the first-level silo reaches a preset first number, the longitudinal rib transfer mechanism is activated to laterally transfer the wire longitudinal ribs in the first-level silo to the second-level silos of each rack of the wire longitudinal rib silo. Step S3: Continue production until the number of wire longitudinal ribs falling into the first-level hopper reaches the preset second quantity; Step S4: Execute the longitudinal rib transfer mechanism again, so that the longitudinal ribs of the wire in the second-level hopper slide laterally onto the finished product support hopper under the action of gravity through the material guide. At the same time, the longitudinal ribs of the wire in the first-level hopper are transferred to the second-level hopper. Step S5: The pusher rod on the finished product support hopper moves to push all the wire longitudinal ribs that have slid down onto it to one end away from the wire longitudinal rib hopper, so that they are neatly arranged; Step S6: Repeat steps S1 to S4 to produce the next set of wire longitudinal reinforcement and transfer it to the finished product support silo, arranging it side by side with the previously neatly arranged wire longitudinal reinforcement to complete the wire longitudinal reinforcement placement of the bottom web reinforcement cage of the entire precast beam.

[0018] Furthermore, before step S4, the following steps are included: the lifting support unit rises, and the material passing rod limit seat at its top supports the material passing guide; after the longitudinal reinforcement of the wire rod of the bottom web reinforcement cage of the whole precast beam is completed, the lifting support unit descends, and the movable material passing rod of the material passing guide rotates downward to the vertical state, so as to separate and avoid the finished product support hopper.

[0019] The beneficial effects of this invention are: By setting up multi-level silos (first-level silo, second-level silo) and finished product support silos, and in conjunction with the longitudinal rib transfer mechanism and material guide components, the system achieves automatic temporary storage, batch transfer, and orderly arrangement of the wire longitudinal ribs output from upstream equipment. The entire process requires no manual intervention, significantly reducing reliance on manual labor and improving the continuity of production cycles.

[0020] In the finished product support hopper, multiple sets of material-supporting rollers are independently arranged, providing independent support positions for multiple longitudinal wire rods without interference. At the same time, the longitudinal wire rods are uniformly pushed to one side and neatly stacked by the material-pushing guide, providing a clear and orderly working interface for the subsequent forming of the steel cage. This effectively avoids the mutual interference problem that occurs when multiple longitudinal wire rods are interlaced, and greatly reduces the difficulty of sorting and positioning operations.

[0021] This invention replaces the tedious traditional manual method of inserting and transporting steel bars one by one by automating the storage, transfer and organization process, which greatly shortens the auxiliary time for laying the longitudinal reinforcement of wire rods, thereby significantly improving the overall efficiency of precast beam steel cage production.

[0022] Each functional module (such as the longitudinal reinforcement transfer mechanism, movable guide group, fixed guide group, and lifting support unit) adopts a modular design, resulting in a compact and rational structure. Key components, such as gear and rack transmission, expansion sleeve connection, and guide rail slider guidance, ensure the accuracy and stability of the mechanism's movement. It possesses excellent durability and repeatability, ensuring reliability in long-term, high-frequency production environments. With a clear structure and well-defined operational logic, it is easily integrated into existing intelligent precast beam production lines. Its strong adaptability and stability contribute to the standardization and modularization of precast beam bottom and web reinforcement cage production, making it a core piece of equipment in modern intelligent precast beam production lines with broad application prospects and significant industrial promotion value.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 , Figure 2 , Figure 12 As shown, the present invention provides a precast highway beam wire rod production and storage mechanism, including: wire rod longitudinal reinforcement silo 1 and finished product support silo 2. Figure 1 The positional relationship between this mechanism and the upstream straightening machine 3, the squirrel cage 4, and the disc frame 5 is shown. Figure 2 The overall structure of the wire rod longitudinal rib hopper 1 is shown. Figure 12This is a side view schematic diagram illustrating the lateral upstream-downstream relationship between the wire rod longitudinal reinforcement hopper 1 and the finished product support hopper 2. In a specific application scenario, this mechanism works collaboratively with the upstream straightening machine 3, the squirrel cage 4, and the coiling frame 5. The straightening machine 3, the squirrel cage 4, and the coiling frame 5 are all common upstream equipment in this field and will not be described in detail here.

[0039] See Figure 2 The wire rod longitudinal reinforcement hopper 1 is constructed along the longitudinal reinforcement conveying direction (i.e., Figure 2 The wire rod longitudinal reinforcement racks 6, 7, 8, and 9 are arranged sequentially from left to right. The finished product support bin 2 is located transversely downstream of the wire rod longitudinal reinforcement bin 1. Figure 12 As shown, the finished product support silo 2 is located to the left of the wire rod longitudinal reinforcement silo 1.

[0040] like Figure 2 , Figure 12 As shown, the wire rod longitudinal reinforcement hopper 1 also includes a guiding device, which includes horizontally arranged angle steel (i.e., the first longitudinal reinforcement guide 10, the second longitudinal reinforcement guide 11, and the third longitudinal reinforcement guide 12) and an L-shaped limiting piece (i.e., an attached plate) disposed above the angle steel. Figure 12 The first longitudinal rib limiter 13 shown is used. Angle steel is used to support and guide the longitudinal ribs of the wire rod. The L-shaped limiter is used to restrict the longitudinal ribs from turning upwards, ensuring that the longitudinal ribs can only fall into the first-level hopper B12 from the opening side of the angle steel directly opposite the opening. A sealing steel plate (i.e., attached) is provided at the end of the guiding device. Figure 12 The second longitudinal rib limiter 14 shown is used to longitudinally limit the longitudinal ribs of the wire rod, preventing them from being thrown out of the hopper due to inertia. The sealing steel plate is as follows: Figure 2 As shown, it is located at the end of the wire rod longitudinal reinforcement hopper 1, away from the straightening machine 3.

[0041] like Figure 3 and Figure 12 As shown, the structure of the material rack is illustrated using the first wire rod longitudinal reinforcement rack 6 as an example. The rack includes multiple crossbeams (the crossbeams of the first material rack 15) spaced apart along the longitudinal reinforcement conveying direction. Each crossbeam is inclined downwards towards the finished product support hopper 2. Upper, middle, and lower columns are sequentially arranged along the inclined direction of each crossbeam, thus dividing the area above the crossbeam into the first-level hopper B12 and the second-level hopper B13, which are sequentially distributed along the inclined direction of the crossbeam. Specifically, the high end of the crossbeam is the end furthest from the finished product support hopper 2, so that the wire rod longitudinal reinforcement can slide from the first-level hopper B12 to the second-level hopper B13 under gravity; the area between the upper and middle columns is the first-level hopper B12, and the area between the middle and lower columns is the second-level hopper B13. The height of the middle column of the crossbeam is lower than the height of the lower column.

[0042] A material guide is provided laterally downstream of the wire rod longitudinal reinforcement hopper 1 on the material rack, for guiding the wire rod longitudinal reinforcement of the second-level hopper B13 to the finished product support hopper 2. The material guide is located on the lower column side of the crossbeam.

[0043] It should be noted that the material rack not only has horizontal beams, but also longitudinal beams, columns and other structures connected to it, which are ultimately connected to form a frame structure.

[0044] See Figure 3 , Figure 12 and Figure 13 The longitudinal rib transfer mechanism includes a top plate 21 and a first cylinder group B2 for the longitudinal rib hopper. The top plate 21 is disposed on one side of the crossbeam and is vertically movable with the material rack. The upper surface of the top plate 21 is a stepped surface that slopes downward toward the finished product support hopper 2. The stepped surface includes a first-level top plate 211 and a second-level top plate 212 that rise in stages. The first-level top plate 211 is the end of the stepped surface away from the finished product support hopper 2, and the second-level top plate 212 is the end closer to the finished product support hopper 2. The first-level top plate 211 extends from the first-level hopper B12 to the second-level hopper B13. In the initial position, the first-level top plate 211 is lower than the crossbeam, and the second-level top plate 212 is flush with the upper surface of the crossbeam in the second-level hopper B13, supporting the longitudinal ribs of the wire rod together with the crossbeam in the second-level hopper B13. After the top plate 21 rises to the target height, the secondary top surface 212 rises from the second-level hopper B13, with its end extending to the material guide. The first cylinder group B2 of the longitudinal rib hopper drives the top plate 21 to rise and fall, so that the primary top surface 211 is periodically higher than the middle column, and the secondary top surface 212 is periodically higher than the lower column.

[0045] like Figure 12 As shown (with the top plate in a low position), the wire rod longitudinal ribs are placed in the first-level hopper B12 and the second-level hopper B13. When the top plate 21 rises (as shown in the image), the wire rod longitudinal ribs are placed in the first-level hopper B12 and the second-level hopper B13. Figure 13 As shown, the primary top surface 211 lifts the longitudinal wire rods resting on the first-level hopper B12, causing them to pass over the central column. The longitudinal wire rods slide down the primary top surface 211 and gather at the corner of the primary top surface 211 near the secondary top surface 212. Meanwhile, the longitudinal wire rods originally on the secondary top surface 212 slide down the inclined secondary top surface 212 onto the material guide. When the top plate 21 descends, the longitudinal wire rods gathered at the corner of the primary top surface 211 sit on the second-level hopper B13 area on the crossbeam. When the top plate 21 rises again, the secondary top surface 212 lifts the longitudinal wire rods in the second-level hopper B13, causing them to pass over the lower column and slide down the secondary top surface 212 toward the material guide.

[0046] To ensure the stability and accuracy of the movement of the top plate 21, the first wire longitudinal rib rack 6 is also equipped with a top plate limiter 22, which is a vertically installed limit bar that allows the top plate to rise and fall only vertically. The top plate limiter 22 is installed on the inner side of the column of the first rack 15, and each top plate unit is independently set to limit the travel range of the top plate 21, prevent the top plate 21 from overtraveling or swaying, and ensure the reliability of the lifting action.

[0047] Material handling guides include movable guide groups and fixed guide groups.

[0048] See Figures 3 to 6 The movable guide group includes a rotating shaft 16, a material guide rod rotation drive mechanism, and multiple movable material guide rods 17 arranged sequentially along the longitudinal rib conveying direction. Figure 3 The diagram shows three movable feed rods 17. The rotating shaft 16 is rotatably mounted on the material rack. Specifically, the first material rack 15 is integrally provided with mounting holes for mounting a seated bearing B1. The rotating shaft 16 is mounted on the first material rack 15 via the seated bearing B1, which provides stable rotational support for the rotating shaft 16, reduces friction, and ensures rotational accuracy. The movable feed rods 17 are fixed to the rotating shaft 16 via movable feed rod mounting seats 18. The movable feed rod mounting seats 18 are assembled onto the rotating shaft 16, and after clamping, circumferential fixation and torque transmission are achieved via a flat key B3. The flat key B3 is embedded in the keyway between the rotating shaft 16 and the movable feed rod mounting seat 18, which can reliably transmit rotational torque and prevent relative slippage. The feed rod rotation drive mechanism is mounted on the material rack to... Figure 3 For example, the material feeder rotation drive mechanism is installed on the first material rack 15 and connected to the rotating shaft 16. It drives the rotating shaft 16 to rotate, thereby causing the three parallel movable material feeders 17 on the rotating shaft 16 to rotate synchronously, so that they are inclined to overlap the finished product support hopper 2 or stand upright away from the finished product support hopper 2.

[0049] The material feeder rotation drive mechanism includes a gear 26, a rack 25, and a second cylinder group B6 for the longitudinal rib hopper. The gear 26 is mounted on the rotating shaft 16 and meshes with the rack 25. To achieve a keyless connection between the gear 26 and the rotating shaft 16, a shrink sleeve B5 is used to install the gear 26 at one end of the rotating shaft 16. The shrink sleeve B5 applies axial clamping force through high-strength bolts, causing radial deformation of the inner and outer conical rings. Friction is used to achieve a keyless connection between the shaft and the hub, which can transmit combined loads such as torque and axial force, and has the advantages of high centering accuracy and convenient assembly and disassembly. The piston rod of the second cylinder group B6 for the longitudinal rib hopper is connected to the rack 25 through a cylinder connector 27. Specifically, the upper end of the second cylinder group B6 is fixed to a cylinder mounting seat 28, which is then fixed to the first material rack 15. The cylinder connector 27 is connected to the slide rail mounting plate 24 through fasteners, providing power input to the system. The rack 25 is fixed to the slide rail mounting plate 24, which is linearly guided by the linear slide rail B4 and the slider mounting plate 23. The slider mounting plate 23 is fixed to the column of the first material rack 15. The linear slide rail B4 is installed on the slider mounting plate 23 by fasteners. One side of the slide rail mounting plate 24 is designed with a tolerance groove to ensure the motion accuracy and straightness of the linear slide rail B4. The second cylinder group B6 of the longitudinal rib hopper drives the rack 25 to move linearly, thereby driving the gear 26 and the rotating shaft 16 to rotate, so as to realize the switching of the movable feed rod 17 between the inclined state and the vertical state.

[0050] To prevent excessive impact from inertia during the rotation of the movable feed rod 17, a feed rod buffer pad 20 is provided on the first feed rack 15. The feed rod buffer pad 20 is made of rubber and is installed at the abutment position when the movable feed rod 17 is in the upright position. It is used to buffer the impact force generated by the inertia of the movable feed rod 17, protecting the mechanism and reducing noise. Simultaneously, to protect precision components such as the gear and rack transmission pair, a gear guard 19 is provided. The gear guard 19 is installed in the appropriate position with fasteners, covering the gear and rack area to ensure operational safety.

[0051] Please see Figures 7 to 9 The fixed guide group includes multiple fixed feed rods 29 arranged sequentially along the longitudinal rib conveying direction. Each fixed feed rod 29 is inclined downwards towards the finished product support hopper 2, with one end fixed to the material rack and the other end resting on the finished product support hopper 2. The fixed feed rods 29 do not require rotation, resulting in a simple and reliable structure. The fixed feed rods 29 and movable feed rods 17 have similar structures, both arranged in parallel, but the difference is that the movable feed rods 17 can rotate, while the fixed feed rods 29 do not require rotation.

[0052] The multiple feed racks arranged sequentially along the longitudinal rib conveying direction include a first wire longitudinal rib feed rack 6, a second wire longitudinal rib feed rack 7, a third wire longitudinal rib feed rack 8, and a fourth wire longitudinal rib feed rack 9. The first wire longitudinal rib feed rack 6 is located at the end furthest from the upstream straightener 3, and the fourth wire longitudinal rib feed rack 9 is located at the end closest to the straightener 3.

[0053] The first wire rod longitudinal support rack 6 is equipped with the movable guide group (i.e., the movable feed rod 17 and its driving mechanism). The second wire rod longitudinal support rack 7 is equipped with the movable guide group and / or the fixed guide group. In this embodiment, as... Figure 7 As shown, the second wire rod longitudinal reinforcement rack 7 includes three sets of power lifting units 31 (each set includes a longitudinal reinforcement transfer mechanism, a rotatable movable material passing rod and its drive assembly, with a structure similar to the longitudinal reinforcement transfer mechanism and movable guide group of the first wire rod longitudinal reinforcement rack 6) and one set of fixed lifting units 32 (including a longitudinal reinforcement transfer mechanism and a fixed material passing rod 29). The fixed lifting unit 32 is located at one end of the second wire rod longitudinal reinforcement rack 7 near the third wire rod longitudinal reinforcement rack 8. Figure 8 The third wire longitudinal stiffener rack 8 shown is Figure 9 The fourth wire rod longitudinal reinforcement rack 9 shown is equipped with a longitudinal reinforcement transfer mechanism and a fixed guide group (i.e., a fixed feed rod 29).

[0054] The rack structures of the second wire rod longitudinal rib rack 7, the third wire rod longitudinal rib rack 8, and the fourth wire rod longitudinal rib rack 9 (second rack 30, third rack 33, and fourth rack 34) are similar to those of the first rack 15. They all include inclined crossbeams and corresponding first-level hopper B12, second-level hopper B13, and longitudinal rib transfer mechanism, which will not be described in detail here.

[0055] Please see Figure 1 , Figure 10 , Figure 11 and Figure 12 The finished product support hopper 2 includes multiple sets of fixed support units and multiple sets of lifting support units. Among them, the lifting support unit ( Figure 12 (As shown) is installed on one side of the movable guide group in the corresponding first wire longitudinal rib rack 6 and second wire longitudinal rib rack 7, to cooperate with the movement of the movable feed rod 17; fixed support unit ( Figure 11 It is set on one side of the corresponding second wire longitudinal reinforcement rack 7, the fixed guide group, the third wire longitudinal reinforcement rack 8, and the fourth wire longitudinal reinforcement rack 9.

[0056] The fixed support unit includes a support frame 48, a material-supporting roller 42, and a material-pushing guide mounted on the support frame 48. The support frame 48 is a fixed structure consisting of a connecting plate, reinforcing ribs, and columns welded together to form an integral base without lifting or lowering function.

[0057] The lifting support unit includes a fixed base 35, a movable support 37 that slides vertically with the fixed base 35, and a second cylinder group B11 for driving the movable support 37 to rise and fall. The fixed base 35 is an integral base welded from connecting plates, reinforcing ribs, and columns. To achieve precise guidance of the movable support 37, guide rails B7 are installed on the columns on both sides of the fixed base 35. The movable support 37 is connected to the slider via a slider connecting seat 36. The lower end of the slider connecting seat 36 is connected to the slider via fasteners, and the upper end is fixed to the movable support 37 via fasteners. The second cylinder group B11 for the support hopper is installed in a preset hole on the fixed base 35 via fasteners, and its cylinder rod output end is connected to the bottom of the movable support 37, which can drive the entire movable support 37 to move up and down along the guide rails B7.

[0058] The movable support 37 is equipped with a material-supporting roller 42 and a material-pushing guide. The material-supporting roller 42 is divided into four sections, which are installed in the grooves of the movable support 37 to jointly perform the material-supporting function. To prevent radial runout of the material-supporting roller 42 during movement, support roller clamping plates 38 are installed on both sides of the movable support 37 by fasteners. The support roller clamping plates 38 constrain the ends of the material-supporting roller 42 to ensure its smooth rotation.

[0059] The pusher guide is used to push the wire longitudinal ribs temporarily stored on the material support roller 42 to one end away from the wire longitudinal rib hopper 1, so that they are neatly arranged.

[0060] The material pushing guide includes a pushing rod 43, a first cylinder group B9 supporting the material bin, and a longitudinal rib side limiter 39. The longitudinal rib side limiter 39 is provided on the support fixing frame 48 or movable support 37 at the end of the material supporting roller 42 away from the wire longitudinal rib material bin 1, and is used to prevent the wire longitudinal rib from slipping off the side during material pushing.

[0061] The push rod 43 is disposed on one side of the material support roller 42. The end of the push rod 43 away from the wire longitudinal rib hopper 1 is rotatably connected to the support fixing frame 48 or the movable support 37 via the push rod connecting shaft 40. To ensure flexible rotation, a push rod rotating copper sleeve 41 is fitted on the push rod connecting shaft 40. The copper sleeve has self-lubricating properties and can reduce friction and wear. The end of the push rod 43 near the wire longitudinal rib hopper 1 is connected to the piston rod of the first cylinder group B9 of the support hopper via the cylinder connecting shaft 46 and the connecting shaft pressure plate 47. Specifically, the first cylinder group B9 of the support hopper is installed on the support fixing frame 48 or the movable support 37 via the first cylinder fixing seat 45 (or the second cylinder fixing seat 49). The cylinder connecting shaft 46 is fixed by the connecting shaft pressure plate 47 and cooperates with the first shaft elastic retaining ring B8 or the second shaft elastic retaining ring B10 to achieve axial limitation. The first cylinder group B9 of the supporting hopper drives the push rod 43 to rotate around the push rod connecting shaft 40, so that the local upper end surface of the push rod 43 is periodically higher than the material support roller 42 and remains in an inclined state.

[0062] Please see Figure 10 , Figure 12 The upper surface of the push rod 43 includes an arc-shaped arched surface 421, an arc-shaped concave surface 422, a straight surface 423, and an upward-lifting surface 424 arranged sequentially towards the wire longitudinal rib hopper 1. The arc-shaped arched surface 421 is located above the push rod connecting shaft 40. This shape design allows the flat surface 423 to first lift the wire longitudinal rib when the push rod 43 rotates. Then, the flat surface 423 guides the wire longitudinal rib to roll towards the longitudinal rib side limit 39, passing sequentially through the arc-shaped concave surface 422 and the arc-shaped arched surface 421 before arranging it on the material support roller 42. The upward-lifting surface 424 prevents the wire longitudinal rib from slipping backward during the pushing process, thereby achieving a smooth and orderly pushing action.

[0063] Please see Figure 10 and Figure 11 A feed rod limiting seat 44 is provided on the side of the support fixing frame 48 and / or the movable support 37 near the wire longitudinal rib hopper 1. The feed rod limiting seat 44 is installed by fasteners and is provided with a limiting groove. One end of the fixed feed rod 29 or the movable feed rod 17 of the feed guide rests in the limiting groove. The limiting groove positions and supports the end of the feed rod to prevent it from shifting or falling off when bearing the weight of the wire longitudinal rib, thus ensuring the stability of the feed process.

[0064] The following describes in detail a specific embodiment of the highway precast beam wire production and storage method provided by the present invention, in conjunction with the aforementioned institutions.

[0065] Prerequisites: Before production begins, the movable support 37 of the lifting support unit is in the lowered position, and the movable guide rod 17 of the movable guide group in the first wire longitudinal rib rack 6 and the second wire longitudinal rib rack 7 rotates downward to the vertical position (abutting against the guide rod buffer pad 20), thus achieving separation and avoidance from the finished product support hopper 2.

[0066] Step S1: Start the upstream straightening machine 3, and the wire rod is continuously straightened and conveyed forward. After straightening, the first end of the longitudinal wire rod passes sequentially through the first longitudinal guide 10, multiple sets of second longitudinal guides 11, and the third longitudinal guide 12 (i.e., horizontally set angle steel). Under the restriction of the L-shaped limiting plate (first longitudinal guide 13), the longitudinal wire rod can only fall from the opening side of the angle steel facing the first-level hopper B12. When the longitudinal wire rod is cut by the straightening machine 3, it slides sequentially from the tail end to the head end by inertia, and the end sealing steel plate (second longitudinal guide 14) longitudinally limits the longitudinal wire rod. The sliding longitudinal wire rod falls into the first-level hopper B12 of each material rack. This cycle continues until the first-level hopper B12 contains a preset first number (e.g., 27) of longitudinal wire rods, which corresponds to the number of longitudinal wire rods required on one side of the bottom web reinforcement cage of the half-beam.

[0067] Step S2: When the number of wire longitudinal ribs falling into the first-stage hopper B12 reaches a preset first quantity, the longitudinal rib transfer mechanism is activated. Specifically, the first cylinder group B2 of the longitudinal rib hopper synchronously drives the top plate 21 to rise (e.g., Figure 13 (As shown). The primary top surface 211 of the top plate 21 lifts the wire rod longitudinal reinforcement resting on the first-level hopper B12, causing it to pass over the central column and slide down along the primary top surface 211 to gather at the corner of the primary top surface 211. Subsequently, the top plate 21 descends, and the wire rod longitudinal reinforcement gathered at the corner descends and sits in the lower area of ​​the crossbeam (i.e., the location of the second-level hopper B13). At this point, the lateral transfer of the wire rod longitudinal reinforcement from the first-level hopper B12 to the second-level hopper B13 is completed.

[0068] Step S3: Continue to produce the longitudinal ribs of the wire rod by the straightening machine 3 until the first-level hopper B12 is filled with the second preset quantity (e.g., 28 pieces, totaling 55 pieces).

[0069] Step S4: Before the transfer of the wire longitudinal ribs, the second cylinder group B11 of the support hopper of the lifting support unit drives the movable support 37 to rise, so that the top material guide limit seat 44 supports the material guide (including the movable material guide 17 and the fixed material guide 29). Subsequently, the action of the longitudinal rib transfer mechanism is executed again, but the rising stroke of the top plate 21 is greater: the secondary top surface 212 of the top plate 21 lifts the wire longitudinal ribs on the second-level hopper B13 to the high end of the material guide. Under the action of gravity, the wire longitudinal ribs slide laterally along the inclined material guide to the finished product support hopper 2 below (received by the material support roller 42). At the same time, the 28 newly produced wire longitudinal ribs in the first-level hopper B12 are laterally transferred to the second-level hopper B13.

[0070] Step S5: Driven by the first cylinder group B9 of the support hopper, the push rod 43 on the finished product support hopper 2 rotates around the push rod connecting shaft 40. The flat surface 423 of the push rod 43 first lifts up the longitudinal ribs of the wire, and then the flat surface 423 guides the longitudinal ribs of the wire to roll towards the side limit 39 of the longitudinal rib. After decelerating at the concave surface 422 of the arc surface, it slides down to the support roller 42 after passing the arched surface 421 of the arc surface, until all 27 longitudinal ribs of the wire on the support roller 42 are pushed to one end away from the wire longitudinal rib hopper 1, so that they are neatly stacked.

[0071] Step S6: Repeat steps S1 to S4 to produce the next set of wire longitudinal bars (e.g., 27 bars required for the next precast beam) and transfer them to the finished product support silo 2, arranging them side by side with the previously neatly arranged wire longitudinal bars to complete the wire longitudinal bar placement for the bottom web reinforcement cage of the entire precast beam.

[0072] After the longitudinal reinforcement of the bottom web steel cage is completed, the movable support 37 of the lifting support unit descends, and then the movable guide rod 17 of the movable guide group rotates downward to the vertical position under the drive of the second cylinder group B6 of the longitudinal reinforcement hopper, in preparation for the next production cycle.

[0073] Through the collaborative work of the above methods and mechanisms, the fully automated storage, transfer, organization, and arrangement of wire rod longitudinal bars from upstream equipment to the finished product station were achieved, which greatly facilitated the subsequent assembly of steel cages and significantly improved production efficiency and automation level.

[0074] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
