Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an integral hoisting device for rectangular pier stirrups. Background Technology

[0002] In bridge construction, rectangular piers serve as crucial substructure load-bearing components. Their construction requires the precise hoisting and placement of multiple sets of stirrups, a step that directly impacts construction efficiency and pier quality. Traditional stirrup hoisting methods often employ manual binding and lifting of single sets or simple scaffolding, which have significant technical limitations: single-set hoisting requires repeated binding, lifting, and positioning processes, resulting in cumbersome operations and low efficiency, making it difficult to meet the schedule requirements of large-scale bridge construction; simple scaffolding lacks targeted restraint structures, making lateral displacement and longitudinal movement prone to occur when multiple sets of stirrups are stacked and hoisted, leading not only to stirrup deformation but also potential safety accidents, affecting the quality of subsequent pouring.

[0003] Meanwhile, traditional devices have poor adaptability to stirrups of different widths and stacking heights, requiring customized tools for different specifications, increasing construction costs and equipment management difficulties. Furthermore, the high proportion of manual operation is labor-intensive and prone to human error leading to insufficient installation accuracy, further restricting construction quality. With the increasing demands for construction efficiency and safety in modern bridge engineering, traditional hoisting methods are no longer sufficient. The industry urgently needs a specialized device capable of efficiently and stably hoisting multiple sets of stirrups, adaptable to various specifications, to solve the problems of low efficiency, poor stability, and insufficient adaptability of existing technologies. Utility Model Content

[0004] The main purpose of this utility model is to provide an integral hoisting device for rectangular pier stirrups, which can effectively solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rectangular pier stirrup hoisting device includes an assembly frame, a bearing plate fixedly connected to the bottom of the assembly frame, multiple sets of movable slots opened on the inner side of the bearing plate, an adjustment component provided on the inner side of the movable slots, a cover plate hinged to the top of the assembly frame, and a fixing component provided at the bottom of the cover plate.

[0006] Preferably, the adjusting assembly includes a bidirectional threaded rod A rotatably connected to the inner side of the movable groove, with limit rods threadedly connected to both sides of the bidirectional threaded rod A, and the limit rods are slidably connected to the inner side of the movable groove. One end of the bidirectional threaded rod A extends to the outer side of the bearing plate, and a bevel gear A is fixedly connected to the other end.

[0007] Preferably, a transmission rod is rotatably connected to the side of the assembly frame near the bevel gear A, and multiple sets of bevel gears B are fixedly connected to the outside of the transmission rod. A throttle is fixedly connected to one end of the transmission rod extending to the outside of the assembly frame.

[0008] Preferably, there are multiple sets of bevel gears A, and each set of bevel gears A and bevel gears B are meshed together.

[0009] Preferably, the fixing assembly includes two sets of fixing plates fixedly connected to one side of the bottom of the cover plate, and a bidirectional threaded rod B is rotatably connected between the two sets of fixing plates. A rotating wheel is fixedly connected to one end of the bidirectional threaded rod B extending to the outside of the fixing plate. A connecting rod seat is threadedly connected to the outside of the bidirectional threaded rod B, and a lower pressure frame is fixedly connected to the other end of the connecting rod seat.

[0010] Preferably, a fixing sleeve is fixedly connected to both sides of the bottom of the cover plate, a connecting rod is slidably connected to the inner side of the fixing sleeve, and one end of the connecting rod is fixedly connected to the surface of the lower pressure frame. A lower pressure spring is fixedly connected between the connecting rod and the inner side of the fixing sleeve, and multiple sets of through grooves are opened on the surface of the lower pressure frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By adjusting the components and using the throttle to drive the transmission rod to rotate, multiple sets of bevel gears B and bevel gear A can be meshed and driven simultaneously, which can drive multiple sets of bidirectional threaded rods A to operate, simplifying the operation process and reducing the workload of operators. On the other hand, the bidirectional thread characteristics of the bidirectional threaded rods A, combined with the sliding connection between the limiting rod and the movable groove, can drive the limiting rods on both sides to move in opposite directions. This can achieve a stable initial lateral limit by squeezing the inside of the stirrup, preventing the multiple sets of stirrups from shifting due to uneven limiting during the subsequent hoisting preparation stage. It can also flexibly adjust the limiting spacing according to the rectangular pier stirrups of different widths and specifications, improving the adaptability of the device to different construction needs. There is no need to equip it with special limiting equipment, reducing construction costs.

[0012] 2. The fixing component drives the bidirectional threaded rod B via a rotating wheel, which in turn moves the connecting rod seat, causing the pressure frame to move smoothly downwards along the limit rod. Combined with the elastic structure consisting of the connecting rod, fixing sleeve, and pressure spring, it provides continuous and adaptive downward pressure to the top of the stirrups. This avoids excessive compression that could deform or damage the stirrups, while also ensuring a tight fit between multiple sets of stirrups at different stacking heights. This effectively limits longitudinal sway during hoisting, improving the overall durability and construction safety of the device, and further enhancing the efficiency and quality of the rectangular pier stirrup hoisting operation.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-2 As shown, a rectangular pier stirrup hoisting device includes an assembly frame 1. A bearing plate 2 is fixedly connected to the bottom of the assembly frame 1. Multiple sets of movable grooves 3 are opened on the inner side of the bearing plate 2. Adjustment components 4 are provided on the inner side of the movable grooves 3. A cover plate 5 is hinged to the top of the assembly frame 1. A fixing component 6 is provided at the bottom of the cover plate 5. First, the cover plate 5, which is hinged to the assembly frame 1, is flipped upward to expose the bearing surface of the bearing plate 2. Then, multiple sets of rectangular pier stirrups to be hoisted are placed on the bearing plate 2. The adjustment components 4 in the movable grooves 3 on the inner side of the bearing plate 2 are used to initially limit the stirrups laterally. After the limiting is completed, the cover plate 5 is flipped downward so that the fixing component 6 at the bottom of the cover plate 5 corresponds to the top of the stirrup. The longitudinal fixing of the stirrup is achieved by the fixing component 6. After the fixing is completed, the hoisting equipment is connected to the assembly frame 1 to carry out the overall hoisting. After hoisting to the target position, the cover plate 5 is opened in reverse to release the limiting of the fixing component 6 and the adjustment component 4, and the stirrup can be taken out.

[0017] like Figures 1-3As shown, the adjusting assembly 4 includes a bidirectional threaded rod A401 rotatably connected to the inner side of the movable groove 3. Limiting rods 402 are threadedly connected to both sides of the bidirectional threaded rod A401, and the limiting rods 402 are slidably connected to the inner side of the movable groove 3. One end of the bidirectional threaded rod A401 extends to the outer side of the bearing plate 2, and a bevel gear A403 is fixedly connected to the other end. A transmission rod 404 is rotatably connected to the side of the assembly frame 1 near the bevel gear A403. Multiple sets of bevel gears B405 are fixedly connected to the outer side of the transmission rod 404. A throttle 406 is fixedly connected to the outer side of the transmission rod 404 extending to the outer side of the assembly frame 1. There are multiple sets of bevel gears A403, and each set of bevel gears A403 is meshed with bevel gears B405. During operation, only the outer side of the assembly frame 1 needs to be rotated... The throttle handle 406 on the side drives the transmission rod 404 fixed thereto to rotate on the assembly frame 1. The multiple sets of bevel gears B405 on the outer side of the transmission rod 404 rotate together. Since each set of bevel gears B405 meshes with the bevel gear A403 at the end of the bidirectional threaded rod A401, the bevel gears B405 transmit power to the bevel gears A403, thereby driving the bidirectional threaded rod A401 to rotate in the movable groove 3 of the bearing plate 2. When the bidirectional threaded rod A401 rotates, the limiting rods 402 connected by threads on both sides will move in opposite directions along the guide of the movable groove 3 until they are in close contact with the inner side of the multiple sets of rectangular pier stirrups, completing the initial lateral limiting of the stirrups, simplifying the operation process, and avoiding the displacement of multiple sets of stirrups due to uneven limiting.

[0018] like Figures 4-5 As shown, the fixing assembly 6 includes two sets of fixing plates 601 fixedly connected to one side of the bottom of the cover plate 5. A bidirectional threaded rod B602 is rotatably connected between the two sets of fixing plates 601. A rotating wheel 605 is fixedly connected to one end of the bidirectional threaded rod B602 extending to the outside of the fixing plate 601. A connecting rod seat 603 is threadedly connected to the outside of the bidirectional threaded rod B602. A lower pressure frame 604 is fixedly connected to the other end of the connecting rod seat 603. Fixing sleeves 606 are fixedly connected to both sides of the bottom of the cover plate 5. A connecting rod 607 is slidably connected to the inside of the fixing sleeve 606, and one end of the connecting rod 607 is fixedly connected to the surface of the lower pressure frame 604. A lower pressure spring 608 is fixedly connected between the connecting rod 607 and the inside of the fixing sleeve 606. The surface of the lower pressure frame 604 is open. Multiple sets of through slots are provided. The operator rotates the wheel 605 on the outside of the fixed plate 601, which drives the bidirectional threaded rod B602 to rotate between the two sets of fixed plates. This causes the connecting rod seat 603 connected by the outer thread to move towards each other, thereby pushing the pressure frame 604 to move smoothly down through the through slot along the limit rod 402. During the downward movement, the connecting rod 607 connected to the pressure frame slides in the fixed sleeve 606 and compresses the pressure spring 608. The spring force is used to press the pressure frame tightly against the top of the multiple sets of stirrups, completing the longitudinal fixation. When unlocking, rotating the wheel in the opposite direction can make the pressure frame move up and reset. It can provide continuous and adaptive pressure, avoid excessive compression and damage to the stirrups, and adapt to multiple sets of stirrups with different stacking heights, effectively limiting their longitudinal sway during hoisting.

[0019] The working principle of this utility model is as follows: During operation, the cover plate 5, which is hinged to the assembly frame 1, is first flipped upwards, and the multiple sets of rectangular pier stirrups to be hoisted are placed on the bearing plate 2 fixed at the bottom of the assembly frame 1; then the adjustment component 4 is operated, and the handle 406 on the outside of the assembly frame 1 is rotated, which drives the transmission rod 404 and the multiple sets of bevel gears B405 on the outside to rotate. Through the meshing transmission between the bevel gears B405 and the bevel gears A403 at the end of the bidirectional threaded rod A401, the bidirectional threaded rod A401 is driven to rotate in the movable groove 3 of the bearing plate 2, so that the limiting rods 402 connected by threads on both sides of the bidirectional threaded rod A401 slide in the opposite direction along the movable groove 3 until they are in close contact with the inner side of the multiple sets of stirrups, thus completing the initial lateral limiting. Next, flip the cover plate 5 downwards, operate the fixing component 6, and rotate the wheel 605 on the outer side of the fixing plate 601. This drives the bidirectional threaded rod B602 to rotate, causing the outer connecting rod seat 603 to move towards each other. This pushes the lower pressure frame 604 to move smoothly downwards along the limiting rod 402 through the through groove. During the downward movement, the connecting rod 607 slides within the fixing sleeve 606 and compresses the lower pressure spring 608. The spring force allows the lower pressure frame 604 to be tightly pressed against the top of the stirrup, achieving longitudinal fixation. Finally, connect the hoisting equipment to the assembly frame 1 for overall hoisting. After reaching the target position, rotate the wheel 605 and the handle 406 in the opposite direction to release the longitudinal fixation and lateral limiting. Flip the cover plate 5 to remove the stirrup.
