Description

Technical Field

[0001] This invention relates to a web stirrup placement device and its application method, and more particularly to a web stirrup placement device and its application method based on a three-in-one stirrup highway box girder jig. Background Technology

[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside with flanges on both sides of the upper part, resembling a box, hence its name. They are classified as single-box or multi-box types. During the fabrication of highway box girders, web stirrups need to be placed in the girder formwork. Therefore, the web stirrup placement device for reinforced highway box girder formwork is an important construction device. In existing reinforced highway box girder formwork web stirrup placement devices, workers perform batch storage, transportation, hoisting, and placement, which has the following technical drawbacks: First, traditional transportation machinery uses mechanical grippers or grabbing robots for transportation and storage, but these devices can only transport 3-4 rebars at a time, resulting in low transportation efficiency and easy machine damage. Second, the transportation and unloading of the combined rebar skeleton are all done by workers. Therefore, the batch storage, transportation, hoisting, and placement of the skeleton is very labor-intensive, and safety accidents are prone to occur during hoisting and transportation, thus affecting the efficiency of web stirrup placement.

[0003] This invention, through its technical feature of pre-placing the web stirrups of the fabric in a row-type storage bin within the girder frame of a highway box girder, effectively explores and studies the technical problems of batch storage, transfer, hoisting, and placement for workers.

[0004] The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on August 15, 2024, which addresses practical technical problems encountered during the work process, and similar patent documents obtained through searching, including a highway steel box girder stabilization hoisting device and its hoisting construction method (CN 113788413A) and a rebar transfer device (CN 112027713 A), and the existing technical problems, technical features, and technical effects in the background art, this application's technical solution is proposed.

[0005] A stabilizing hoisting device for highway steel box girders and its hoisting construction method (CN 113788413 A): This device relates to the field of steel box girder construction technology, specifically a stabilizing hoisting device for highway steel box girders. It includes a first transport vehicle and a second transport vehicle. The first transport vehicle is equipped with a work platform, and a horizontally rotatable main turntable is mounted on the work platform via bearings. The hoisting method includes steps such as equipment positioning, hoisting preparation, lifting, and adjusting and lowering the steel box girder. The advantages are: this device can utilize the first and second transport vehicles to transport larger hoisting mechanisms, thus providing a longer hoisting distance and a greater lifting weight. Furthermore, by changing the support position of the jacking pusher on the main pusher, it can freely adjust between greater lifting mass and higher lifting height. The distributed support of the main pusher by two transport vehicles in this device also provides better stability compared to existing hoisting equipment using a single transport vehicle, thus making it safer to use.

[0006] Technical drawbacks exist:

[0007] In terms of safety, the hoisting of the steel reinforcement cage requires hoisting equipment, which poses certain operational risks.

[0008] In terms of quality, since the bottom and top reinforcement cages of the secondary beams and hollow slab beams need to be positioned separately on the jig, it is difficult to guarantee the positioning accuracy during the positioning process, which poses a certain quality risk.

[0009] In terms of construction efficiency, the steel reinforcement cages are transported by hoisting equipment, which is time-consuming and inefficient. Furthermore, since the steel reinforcement cages for the bottom and top slabs of the secondary beams and hollow slab beams need to be positioned separately on the jig, it is difficult to guarantee positioning accuracy. This affects the efficiency and quality of steel reinforcement transfer and unloading, resulting in significant rework and increased time costs.

[0010] A rebar transfer device (CN 112027713 A): The rebar transfer device includes two quarter-circle arc-shaped slide rails arranged side-by-side with their openings facing upwards to the right. An arc-shaped plate coaxial with the inner side of each slide rail is provided. A slanted cut is provided on the right side of the arc-shaped plate, with the front end of the cut higher than the rear end. Multiple stop bars are evenly distributed axially along the inner arc surface of the arc-shaped plate near the cut end. The stop bars are detachably installed inside the arc-shaped plate, with their free ends inclined away from the opening of the arc-shaped plate. An arc-shaped rack coaxial with the outer arc surface of the arc-shaped plate is fixed. A gear driven by a motor and meshing with the arc-shaped rack is fixed to the upper left of the frame. A horizontally extending support is fixed to the front end of the frame, and a vertical electric push rod is fixed to the front end of the support. An L-shaped rod is fixed to the extended end of the electric push rod, with the horizontal end of the L-shaped rod fixed to the extended end of the electric push rod. An electromagnet is connected to the vertical end of the L-shaped rod. This device effectively solves the problems of high labor intensity and inconvenient loading during existing rebar transfer processes.

[0011] Technical drawbacks exist:

[0012] Limited applicability: One type of rebar transfer device is only suitable for stirrups of a specific size or type. If the rebar specifications vary significantly, the tool may not be adaptable to all situations, requiring additional adjustments or replacement.

[0013] Low efficiency: Since the magnet can only attract one steel bar at a time, the entire device operates in low efficiency, and operators may need to spend extra time adjusting the tools, which greatly affects the transfer efficiency. Summary of the Invention

[0052] This invention designs a system in which the centerline of the frame, the centerline of the rod fabric assembly, and the centerline of the operating platform are aligned on the same straight line. Two follower wheels are mounted on the frame, and two drive wheels are mounted on the frame. Support frame part V is connected to support frame part I. The wire rope of the winch is connected to the drop plate part and the lug part, respectively. Support frame part IV, wheel seat part II, wheel seat part I, connecting rod part, spring part, and connecting block part are connected to support frame part I and support frame part II, respectively. The plug-in block part is connected to the clamping block part.

[0053] This invention designs a method for using a web stirrup placement device based on a three-in-one stirrup highway box girder jig. The steps are as follows: the vehicle chassis moves along the transverse centerline of the highway box girder jig; the rod placement assembly stores and unloads the web stirrups on the chain; and the web stirrups in the highway box girder jig are pre-placed in an array storage bin.

[0054] The technical effects of the above technical solutions are: highlighting the technical feature of pre-placing the web stirrups of the highway box girder jig in an arranged storage bin, and introducing its application in the technical field of web stirrup placement device based on the three-in-one stirrup highway box girder jig.

[0055] The present invention comprises the following steps: Based on the specifications of the web reinforcement, select the corresponding frame, rod fabric assembly, and operating platform; lift support frame III; place the plug-in blocks into the clamping blocks located on support frame I and support frame II respectively; connect the connecting flanges of docking frame I and docking frame II together using bolts and nuts; connect support frame IV to support frame I and support frame II; string the wire rope of the winch body into the lug seat; place the wire rope of the winch body onto the outer end face of the plate; place the wire rope hook on the wire rope of the winch onto the side of one of the lug seats; and place the web reinforcement into the V-shaped groove of support frame IV. The operator is positioned on platform I and platform II, activating the motor. The motor rotates on support frame III via shaft wheels I and II, driving chain wheels I and II to rotate around the shaft wheels I and II. Chain wheels I and II then drive the hanging plate section to rotate around support frame III. When the hanging plate section reaches the corresponding rear end of platform I and platform II, the operator picks up the web stirrups or uses a robotic arm to place the horizontal end of the web stirrups into the C-shaped opening of the hanging plate section. This causes the hanging plate section with web stirrups to move towards the lower end of support frame III. The hanging plate section with web stirrups then moves towards the corresponding front end of the plate section, thus achieving the movement at the lower end of support frame III. The web stirrups are suspended and stored at the end face. After the web stirrups are suspended and stored at the lower end face of the support frame III, the motor body is put into a non-working state. When it is necessary to place the web stirrups into the highway box girder jig, the frame is straddled across the highway box girder jig, and the motor body and power motor are put into a working state. The reducer drives the shaft to rotate in the vertical part of the cylinder shell part and the wheel seat part II, driving the wheel part II to rotate in the wheel seat part II, driving the wheel part I to rotate on the wheel seat part I, so that the web stirrups move on the highway box girder jig. When the hanging plate part with web stirrups on the corresponding front end of the plate part reaches the position where the web stirrups need to be placed in the highway box girder jig, the chain conveyor part rotates. When the hanging plate is rotated upwards, the web stirrups on the hanging plate are flipped upwards. At the same time, the winch retracts, causing the rope-laying part to move inwards towards the plate. This causes the plate to exert an upward force on the web stirrups on the hanging plate, separating them from the C-shaped opening of the hanging plate. The web stirrups then fall into the highway box girder frame. The winch releases, separating the rope-laying part from the plate. Under the elastic energy storage of the plate, it returns to its initial state, thus placing the web stirrups into the highway box girder frame. After placing the web stirrups into the highway box girder frame, the vehicle frame is driven off the highway box girder frame, and the motor body and power motor are in a non-operating state.

[0056] The technical effect of the above solution is that it enables the linear motion conveying and rotational motion dropping and placing of the web stirrups.

[0057] In this technical solution, the rod body fabric assembly is the basic component and an essential technical feature of the invention. The frame, follower wheel, power wheel, operating platform, and winch are functional components, features that achieve other technical effects of the invention. The design of the following technical features—support frame I, support frame II, clamping block, docking frame I, docking frame II, support frame III, chain conveyor, hanging plate, pressure plate, drop plate, insertion block, ear seat, axle wheel I, motor body, axle wheel II, chain body I, chain body II, plate, seat I, seat II, wheel seat I, wheel I, docking rod, spring, docking block, wheel seat II, wheel II, reducer, power motor, cylinder shell, shaft, support frame IV, platform I, platform II, support frame V, winch body, and rope arrangement section—complies with the Patent Law and its implementing regulations.

[0058] In this technical solution, the patent number of a three-in-one stirrup frame device is: ZL202222140463.0.

[0059] In this technical solution, the web stirrups of the fabric in the highway box girder jig are pre-placed in an array storage bin by the rod fabric assembly.

[0060] In this technical solution, the key technical feature is the pre-placement of the web stirrups in the highway box girder jig into the vehicle chassis and pole fabric assembly in an array storage bin. In the technical field of web stirrup fabric device and usage method based on three-in-one stirrup highway box girder jig, this solution is novel, inventive and practical.

[0105] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0106] A method for using a web stirrup placement device based on a three-in-one stirrup highway box girder formwork, the steps of which are as follows:

[0107] According to the specifications of the web stirrups, select the corresponding frame 1, pole fabric assembly 2, and operating platform 5. Lift the support frame section III 21, place the insertion block section 26 into the clamping block section 13 located on the support frame section I 11 and support frame section II 12 respectively, and connect the connecting flange of the docking frame section I 14 and the connecting flange of the docking frame section II 15 together with bolts and nuts. Connect the support frame section IV 51 to the support frame section I 11 and support frame section II 12. String the wire rope of the winch body 62 into the ear seat section 27, place the wire rope of the winch body 62 onto the outer end face of the plate section 251, place the wire rope hook on the wire rope of the winch 6 onto the side of one of the ear seats 27, place the web stirrups into the V-shaped groove of the support frame section IV 51, and have the operator positioned on the platform section I 52 and platform section II 53 to put the motor body 222 into working condition, through the shaft wheel body I 221 and... The axle wheel body II223 rotates on the support frame part III21, driving the chain body I224 and chain body II225 to rotate around the axle wheel body I221 and axle wheel body II223. The chain body I224 and chain body II225 drive the hanging plate part 23 to rotate around the support frame part III21. When the hanging plate part 23 reaches the rear end head corresponding to the platform part I52 and platform part II53, the operator picks up the web plate stirrup or the robotic arm moves the web plate stirrup. The horizontal end of the reinforcing bar is placed into the C-shaped opening of the hanging plate part 23, so that the hanging plate part 23 with web stirrups moves at the lower end face of the support frame part Ⅲ21. The hanging plate part 23 with web stirrups moves towards the front end corresponding to the plate part 251, thereby realizing the suspension and storage of web stirrups at the lower end face of the support frame part Ⅲ21. After the suspension and storage of web stirrups at the lower end face of the support frame part Ⅲ21 is completed, the motor body 222 is put into a non-working state.

[0108] When the web reinforcement needs to be placed in the highway box girder jig, the frame 1 is placed across the jig, and the motor body 222 and the power motor 44 are in working condition. The reducer 43 drives the shaft 46 to rotate in the vertical part of the cylinder shell 45 and the wheel seat 41, driving the wheel 42 to rotate in the wheel seat 41, which in turn drives the wheel 1 32 to rotate on the wheel seat 1 31. This causes the web reinforcement to move on the highway box girder jig. When the hanging plate 23 with the web reinforcement on the front end corresponding to the plate 251 reaches the position where the web reinforcement needs to be placed in the highway box girder jig, the hanging plate 23 rotates upward under the action of the chain conveyor 22, and the web reinforcement on the hanging plate 23 moves into place. The vehicle rotates upwards while the winch 62 retracts, causing the rope section 63 to move inwards toward the plate section 251. This causes the plate section 251 to exert an upward force on the web stirrups located on the hanging plate section 23, separating the web stirrups from the C-shaped opening of the hanging plate section 23. The web stirrups then fall into the highway box girder frame. The winch 62 then releases, separating the rope section 63 from the plate section 251. Under the elastic energy storage of the plate section 251, the plate section 251 returns to its initial state, thus placing the web stirrups into the highway box girder frame. After placing the web stirrups into the highway box girder frame, the vehicle frame 1 is driven off the highway box girder frame, and the motor body 222 and the power motor section 44 are put into a non-working state.

[0109] In verifying this invention, the inventors abandoned the existing technical features of batch storage, transfer, hoisting, and placement by workers. They first proposed a technical feature of pre-placing the web stirrups in the highway box girder jig in an arranged storage bin. This resulted in the first unexpected technical effect: enabling one-time fabrication of the web stirrups in the highway box girder jig, improving the manufacturing efficiency of the highway box girder. The second unexpected technical effect: enabling centralized arrangement and storage of the web stirrups, facilitating centralized inspection of the web stirrups, and improving the manufacturing effect of the highway box girder. The third unexpected technical effect... The system achieves several unexpected technical effects: 1) precise positioning on the highway box girder jig and flipping and detaching of the web stirrups, improving the placement accuracy of the web stirrups; 2) large-volume storage of web stirrups and placement operations between different highway box girder jigs, resulting in a fifth unexpected technical effect; 3) applying external interference force to plate 251, improving the accuracy of separation between the web stirrups and hanging plate 23, resulting in a sixth unexpected technical effect; 4) the installation of platform I 52 and platform II 53 on the frame 1, facilitating operation for personnel.

[0110] In a second embodiment of the present invention, the vehicle chassis and the pole fabric assembly 2 are interconnected by pre-placing the web stirrups of the fabric in the highway box girder frame in an array storage bin.

[0111] In this embodiment, the rod material assembly 2 is connected to the vehicle chassis in a manner that stores and cuts the web stirrups on the chain.

[0120] 2. Due to the design of the frame 1, follower wheel 3 and drive wheel 4, a self-propelled vehicle body support was achieved.

[0121] 3. The design of the operating platform 5 provides support for operators.

[0122] 4. Due to the design of the winch 6, force is generated on the pole material assembly 2.

[0123] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0124] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.
