Description

Technical Field

[0001] This utility model specifically relates to a safety hanging basket for bridge construction, belonging to the field of bridge construction technology. Background Technology

[0002] Bridge construction is the process of building a bridge according to the design. It mainly refers to bridge construction technology, construction organization, construction management, and construction quality. In bridge construction, the safety formwork (also known as cantilever formwork or construction formwork) is the core equipment of the cantilever casting method (such as segmental construction). It is used to support the formwork, workers, machinery and materials, and must meet the requirements of high strength, stability and safety.

[0003] A search revealed a Chinese patent publication number CN221919035U, which discloses a safety hanging basket for bridge construction. This patent provides a safety hanging basket suitable for under-bridge maintenance, with a base providing continued support to the bottom of the basket, resulting in higher structural stability. In practical use, the hanging components are fixedly connected to the bridge, and the basket assembly is located under the bridge. Workers stand within a space enclosed by a safety fence to perform maintenance. During work, the position of the base plate can be adjusted as needed to easily adjust the work area. However, in this patent, once the hanging components are fixedly connected to the bridge, moving the basket under the bridge requires repeated disassembly, reassembly, and reattachment of the hanging components, which is time-consuming. Especially for large-span bridges requiring multi-point maintenance, frequent disassembly and reassembly exposes workers to near-edge conditions, increasing the risk of falls. If tools or parts fall during disassembly, they could injure personnel or equipment below. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a safe hanging basket for bridge construction. This basket features a moving mechanism that, driven by a first electric push rod, pushes the mounting shell downwards, bringing the drive wheel inside the shell into contact with the bridge. Driven by a first motor, the drive wheel rotates inside the mounting shell, causing the basket to move longitudinally along the bridge to the target work position. Once the basket reaches the target position, a second electric push rod pushes down the first and second mounting frames. The insertion rod at the bottom of the second mounting frame applies pressure to the bridge, preventing the basket from sliding. A damper buffers impact and absorbs vibration, ensuring stable positioning of the moving blocks. This eliminates the need to disassemble and reassemble the connecting parts, effectively improving the moving efficiency of the basket, eliminating repeated high-altitude work, and reducing personnel exposure risks.

[0005] A safety hanging basket for bridge construction includes: a movable block, a moving mechanism, a lifting mechanism, and an adjusting mechanism;

[0006] A moving mechanism includes a driving component and a positioning component, wherein the driving component is used to drive a moving block to move, and the positioning component is used to position the moving block after the moving position.

[0007] The drive assembly includes a first electric push rod, a drive wheel, and a first motor. The output end of the first electric push rod is provided with a mounting shell. The drive wheel is rotatably disposed inside the mounting shell. The first motor is disposed on one side of the mounting shell, wherein the output end of the first motor is connected to one end of the drive wheel.

[0008] The positioning assembly includes a second electric push rod, a first mounting frame, and a second mounting frame. The first mounting frame is located at the output end of the second electric push rod. The bottom end of the first mounting frame is provided with four sets of dampers, the bottom ends of which are connected to the top end of the second mounting frame. The bottom end of the second mounting frame is provided with multiple sets of insert rods. Both the first and second mounting frames are movably located outside the mounting shell.

[0009] Furthermore, the top of the movable block is provided with a mounting groove, the first electric push rod is set inside the mounting groove, the two sets of the second electric push rods are set inside the mounting groove, and the top of the mounting shell is provided with two sets of limiting rods, which movably penetrate the bottom inner wall of the mounting groove.

[0010] Furthermore, an assembly plate is provided at the top of the movable block. The assembly plate is designed in a "U" shape, and a limiting shell is provided on the inner side of the assembly plate.

[0011] Furthermore, the lifting mechanism includes a third electric push rod and a limiting plate. A connecting frame is provided on one side of the third electric push rod, and the limiting plate is located inside the connecting frame. The limiting plate is designed in an "L" shape and can move through the interior of the limiting shell. The output end of the third electric push rod is connected to one side of the assembly plate.

[0012] Furthermore, the adjustment mechanism includes an assembly frame and a threaded rod. The threaded rod is rotatably disposed inside the assembly frame. A second motor is disposed on one side of the assembly frame, and the shaft of the output end of the second motor is connected to one end of the threaded rod.

[0013] Furthermore, the assembly frame is provided with two sets of guide rods inside, which are located on both sides of the threaded rod, and a through groove is provided inside the assembly frame.

[0014] Furthermore, a sliding plate is threaded through the outer side of the threaded rod, and two sets of guide rods move through the interior of the sliding plate.

[0015] Furthermore, two sets of protective sleeves are provided on the outer side of the threaded rod, and both sets of protective sleeves are connected to both sides of the sliding plate. The top of the sliding plate is provided with the basket body.

[0016] Beneficial effects:

[0017] Equipped with a moving mechanism, driven by a first electric push rod, the mounting shell is lowered, bringing the drive wheel inside the shell into contact with the bridge. Driven by a first motor, the drive wheel rotates inside the mounting shell, causing the basket body to move longitudinally along the bridge to the target position. After the basket body reaches the target position, driven by a second electric push rod, the first and second mounting frames are lowered. The insertion rod at the bottom of the second mounting frame presses down on the bridge, preventing the basket body from sliding. The damper buffers the impact force and absorbs vibration, achieving stable positioning of the moving block. There is no need to disassemble or assemble the connecting parts, effectively improving the moving efficiency of the basket body, eliminating repeated high-altitude operations, and reducing personnel exposure risks.

[0018] Equipped with a lifting and adjusting mechanism, and driven by a No. 3 electric push rod, the connecting frame moves the limiting plate up and down within the limiting shell, adjusting the vertical height of the hanging basket body to adapt to changes in the height of the inspection surface under the beam. The sliding of the limiting plate within the limiting shell ensures no swaying during the lifting process, adapting to different beam bottom clearances. When driven by the No. 2 motor, the rotation of the threaded rod allows the sliding plate to move linearly within the assembly frame, enabling fine-tuning of the horizontal position of the hanging basket body and precisely aligning it with the inspection point. The protective sleeve covers and protects the threaded rod, preventing debris from the bridge bottom from clogging the threads and effectively extending the life of the threaded rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a safety hanging basket for bridge construction;

[0028] Includes: moving block 1, moving mechanism, lifting mechanism and adjusting mechanism;

[0029] The moving mechanism includes a driving component and a positioning component. The driving component is used to drive the moving block 1 to move, and the positioning component is used to position the moving block 1 after the moving position.

[0030] The drive assembly includes a first electric push rod 3, a drive wheel 6 and a first motor 7. The output end of the first electric push rod 3 is provided with a mounting shell 4. The drive wheel 6 is rotatably disposed inside the mounting shell 4. The first motor 7 is disposed on one side of the mounting shell 4, wherein the output end of the first motor 7 is connected to one end of the drive wheel 6.

[0031] The positioning assembly includes a second electric push rod 8, a first mounting frame 9, and a second mounting frame 11. The first mounting frame 9 is located at the output end of the second electric push rod 8. The bottom end of the first mounting frame 9 is provided with four sets of dampers 10, the bottom ends of which are connected to the top end of the second mounting frame 11. The bottom end of the second mounting frame 11 is provided with multiple sets of insert rods 12. Both the first mounting frame 9 and the second mounting frame 11 are movably located outside the mounting shell 4.

[0032] The mounting shell 4 integrates the drive wheel 6 and the first motor 7 to form a modular mobile unit, which is easy to maintain. Driven by the first electric push rod 3, the mounting shell 4 can be pushed down so that the drive wheel 6 inside the mounting shell 4 contacts the bridge. Driven by the first motor 7, the drive wheel 6 can rotate inside the mounting shell 4, so that the hanging basket body 26 moves longitudinally along the bridge to the target work position.

[0033] After the hanging basket body 26 reaches the target position, it is driven by the second electric push rod 8 to push the first mounting frame 9 and the second mounting frame 11 downward. The insertion rod 12 at the bottom of the second mounting frame 11 presses down to apply pressure to the bridge. The insertion rod 12 presses down on the bridge surface to generate friction. Multiple sets of insertion rods 12 form distributed pressure points, which enhances the anti-slip effect and prevents the hanging basket body 26 from sliding. The damper 10 is used to buffer the impact force and absorb vibration to complete the stable positioning of the moving block 1. There is no need to disassemble and assemble the hanging parts, which effectively improves the moving efficiency of the hanging basket body 26, eliminates repeated high-altitude operations and reduces the risk of personnel exposure.

[0034] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a safety hanging basket for bridge construction;

[0035] The top of the movable block 1 is provided with an installation groove 2.

The mounting groove 2 provides installation space for the first electric push rod 3 and the second electric push rod 8. The two sets of limiting rods 5 at the top of the mounting shell 4 pass through the bottom inner wall of the mounting groove 2. The limiting rods 5 can limit the movement of the mounting shell 4 up and down, ensuring the stability of the mounting shell 4 during the up and down movement.

[0037] Please see Figure 1 , Figure 2 and Figure 3 As shown, a safety hanging basket for bridge construction;

[0038] The top of the movable block 1 is provided with an assembly plate 13, which is designed in the shape of a "U". The inner side of the assembly plate 13 is provided with a limiting shell 14. The lifting mechanism includes a third electric push rod 16 and a limiting plate 17. A connecting frame 15 is provided on one side of the third electric push rod 16. The limiting plate 17 is located inside the connecting frame 15 and is designed in the shape of an "L". The limiting plate 17 moves through the interior of the limiting shell 14. The output end of the third electric push rod 16 is connected to one side of the assembly plate 13.

[0039] The No. 3 electric push rod 16 is located on one side of the connecting frame 15, and the output end of the No. 3 electric push rod 16 is connected to one side of the "U"-shaped assembly plate 13. When the No. 3 electric push rod 16 is driven, the position between the connecting frame 15 and the assembly plate 13 can be adjusted. The connecting frame 15 drives the limiting plate 17 to rise and fall inside the limiting shell 14, which can adjust the vertical height of the hanging basket body 26 to adapt to the height change of the inspection surface at the bottom of the beam. It is used to cover different beam bottom clearances and has a wider range of applications. By sliding the limiting plate 17 up and down inside the limiting shell 14, it can ensure that there is no sway during the lifting process and adapt to different beam bottom clearances.

It is threaded through the sliding plate 24, and two sets of guide rods 20 inside the assembly frame 18 move through the interior of the sliding plate 24. When driven by the second motor 22, the rotation of the threaded rod 21 enables the sliding plate 24 to move linearly inside the assembly frame 18, achieving fine adjustment of the horizontal position of the hanging basket body 26 and driving the hanging basket body 26 to accurately align with the inspection point. The two sets of guide rods 20 move through the interior of the sliding plate 24 to prevent the sliding plate 24 from rotating and ensure linear displacement accuracy. The protrusion 25 on the outside of the sliding plate 24 moves inside the through groove 19. The through groove 19 can limit the stroke of the sliding plate 24 and prevent the sliding plate 24 from moving beyond its limit. The protective sleeve 23 is a telescopic and foldable sleeve. The protective sleeve 23 can cover and protect the threaded rod 21 to prevent debris from the bottom of the bridge from clogging the threads and effectively extend the life of the threaded rod 21.
