Description

Technical Field

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

[0002] The hanging basket used in bridge crash barrier construction is a suspended work platform that straddles the top of the crash barrier, specifically designed for workers to perform formwork installation, concrete pouring, or repair work on the outside of the wall. It is usually made of a "П" or "U" shaped steel frame, with counterweights on the inside and a basket for carrying workers on the outside. Pullers are arranged on the top and sides, allowing it to slide on the top of the crash barrier after clamping it. Workers can push or electrically drive the hanging basket to move continuously while standing inside, without having to repeatedly enter and exit. This improves efficiency and eliminates the risk of overturning through counterweights and multi-point support, minimizing the risk of falls from height.

[0003] While the hanging basket devices currently used in bridge crash barrier construction basically meet the needs of workers for standing and moving, their structural design still follows the old approach of "integrated welding and fixed dimensions": the two longitudinal main beams, several transverse supports, and the outer cantilevered work basket are all connected into a rigid whole by full welding. After production, the clamping clearance of the hanging basket is locked to a specific crash barrier thickness. Due to the differences in route grade, design load, and landscape requirements of different bridges, the thickness of the crash barrier varies. Even different beam sections of the same bridge may have gradual changes due to expansion joints or curve widening. Once the fixed-size hanging basket encounters a non-standard wall thickness, the awkward situation of "a large horse pulling a small cart" or "a small horse pulling a large cart" will occur.

[0004] When the wall is thin, the clamping gap is too wide, and the entire hanging basket can sway laterally at the top of the wall. The impact load generated when workers pour concrete on the outside is transmitted to the hanging basket through the formwork. The instantaneous horizontal inertial force makes the rollers knock on the top of the wall with a distinct "thump" sound. When the wall is thick, there will be an awkward situation where it cannot be squeezed in. On-site, steel plates can be temporarily added or the hanging basket can be cut, which delays the construction period and damages the structural strength. When workers gather near the outermost railing to vibrate or finish, the center of gravity of the hanging basket shifts outward, and the clamping point cannot provide enough counter-torque. A small horizontal impact may cause the hanging basket to slide along the top of the wall or even flip outward, causing the formwork to misalign, concrete to spill, or even people to fall. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a hanging basket device for bridge construction, which achieves high sensitivity and better information collection.

[0006] A hanging basket device for bridge construction includes a hanging basket body (1) and a fixing component installed on the hanging basket body (1). An adaptive clamping mechanism connected to the fixing component is installed on the hanging basket body (1). The adaptive clamping mechanism includes:

[0007] A fixing frame (6) is slidably mounted on the fixing component, and the fixing frame (6) is provided with a linkage component connected to the fixing component;

[0008] A fixing plate (8) is mounted on the fixing frame (6). A clamping component connected to the linkage component is slidably provided on the fixing plate (8). The clamping component is driven by the linkage component to move synchronously closer to or away from the hanging basket body (1) when the fixing frame (6) slides along the fixing component.

[0009] Furthermore, the fixing component includes:

[0010] The first sliding bar (2) is symmetrically fixed on one side of the hanging basket body (1), and a limit protrusion is fixed on the top of the first sliding bar (2);

[0011] The second sliding bar (3) is symmetrically fixed on the basket body (1) on the side away from the first sliding bar (2). Another limiting protrusion is fixed on the top of the second sliding bar (3). A first toothed rack (4) is fixed on the side of the second sliding bar (3) away from the basket body (1).

[0012] Furthermore, two fixing frames (6) are symmetrically arranged. One end of the fixing frame (6) is slidably engaged with the first sliding bar (2), and a first pulley (7) that is in contact with the first sliding bar (2) is rotatably connected to the fixing frame (6).

[0013] Furthermore, multiple sets of second pulleys (9) are rotatably connected at equal intervals on the fixed plate (8).

[0014] Furthermore, the linkage component includes:

[0015] A fixing rod (10) is fixed between two fixing frames (6), and two second rolling balls (11) are symmetrically installed on the fixing rod (10).

[0016] Gear (12), which rotates symmetrically at both ends of the fixed rod (10), meshes with the first rack (4).

[0017] Furthermore, the clamping assembly includes:

[0018] The plug rod (13) slides on the second pulley (9) and the plug rod (13) is provided with a plug groove (14) that is adapted to slide on the second pulley (9).

[0019] The second rack (15) is fixed at one end of the lower side of the plug rod (13) and meshes with the gear (12). One end of the plug rod (13) is fixed with an abutment structure.

[0020] Furthermore, the resisting structure includes:

[0021] A clamping frame (16) is fixedly connected to the plug rod (13), and a fourth rolling ball (18) is symmetrically installed on the clamping frame (16).

[0022] The third rolling ball (17) is symmetrically installed at the connection between the clamping frame (16) and the plug rod (13).

[0023] Furthermore, two first rolling balls (5) are symmetrically installed on the main body (1) of the hanging basket.

[0024] Beneficial effects:

[0025] This invention utilizes the self-weight of the hanging basket body during lowering to drive the first rack and gear to mesh, thereby causing the plug-in rod and clamping frame to retract laterally, allowing the clamping surface to automatically fit against the crash barrier. This allows the same device to continuously adapt to different wall thicknesses, eliminating the need for repeated disassembly and reassembly of traditional hanging baskets and the adjustment of shims, significantly shortening construction preparation time. The multi-point rolling pair design transforms sliding friction into rolling friction, reducing component wear and pushing resistance, and extending service life. Symmetrically arranged rolling balls and pulleys form a stable clamping closed loop, maintaining zero gap and zero sway under dynamic loads, effectively eliminating safety hazards caused by fit gaps. The overall structure is compact, requiring no external power or manual intervention, achieving "ready to hang and use, clamp as you go," significantly improving the safety and reliability of bridge crash barrier construction while increasing work efficiency.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0036] Please see Figure 1-8 As shown, a hanging basket device for bridge construction includes a hanging basket body (1) and a fixing component installed on the hanging basket body (1). An adaptive clamping mechanism connected to the fixing component is installed on the hanging basket body (1). The adaptive clamping mechanism includes:

[0037] A fixing frame (6) is slidably mounted on the fixing component, and the fixing frame (6) is provided with a linkage component connected to the fixing component;

[0038] A fixing plate (8) is mounted on the fixing frame (6). A clamping component connected to the linkage component is slidably provided on the fixing plate (8). The clamping component is driven by the linkage component to move synchronously closer to or away from the hanging basket body (1) when the fixing frame (6) slides along the fixing component.

[0039] In this implementation, when the main body of the hanging basket (1) is hoisted to the top of the anti-collision wall and slowly lowered, its own weight is first transmitted to the adaptive clamping mechanism through the fixing component. At this time, a relative downward movement is generated between the fixing component and the adaptive clamping mechanism. As the main body of the hanging basket (1) sinks, the fixing component drives the linkage component to move synchronously. The linkage component converts this vertical displacement into a lateral driving force and immediately acts on the clamping component, so that the clamping component is smoothly pushed along the fixing plate (8) towards the side of the anti-collision wall until the clamping surface is tightly attached to the wall.

[0040] The entire clamping stroke is triggered entirely by the weight of the main body of the hanging basket (1). No additional manual adjustment or auxiliary tools are required, which can adapt to different wall thicknesses. The clamping force increases linearly with the weight of the hanging basket, ensuring zero gap and zero shaking under dynamic loads such as concrete vibration, formwork installation and personnel movement. When the construction is completed and relocation is required, simply lift the main body of the hanging basket (1) upwards, the linkage component resets in the reverse direction, the clamping component automatically releases the wall, and the hanging basket can slide to the next work position as a whole. This completely solves the problem of repeated disassembly and reassembly and shim adjustment of traditional fixed-size hanging baskets due to changes in wall thickness, and realizes the true meaning of "hang and use immediately, clamp as you go", which greatly improves the safety and work efficiency of bridge anti-collision wall construction.

[0041] Please see Figure 2 As a technical optimization of this utility model, the fixing component includes:

[0042] The first sliding bar (2) is symmetrically fixed on one side of the hanging basket body (1), and a limit protrusion is fixed on the top of the first sliding bar (2);

[0043] The second sliding bar (3) is symmetrically fixed on the basket body (1) on the side away from the first sliding bar (2). Another limiting protrusion is fixed on the top of the second sliding bar (3). A first toothed rack (4) is fixed on the side of the second sliding bar (3) away from the basket body (1).

[0044] In this implementation, the first sliding bar (2) and the second sliding bar (3) are symmetrically arranged on both sides of the main body of the hanging basket (1) to form a pair of parallel and continuous sliding tracks; the first rack (4) fixed on the outside of the second sliding bar (3) is connected to the linkage component. As the main body of the hanging basket (1) is lowered, the first rack (4) generates a vertical displacement relative to the linkage component. This displacement is precisely converted into the action of driving the linkage component, so that the clamping component tightens or loosens synchronously in the horizontal direction, thereby adapting to the different thicknesses of the anti-collision wall; since the first rack (4) and the second sliding bar (3) are integrally formed rigid structures with continuous tooth shape and high meshing accuracy, even after multiple hoisting or vibration impacts, the transmission error can still be ensured to be minimal and the clamping force constant, truly realizing the adaptive function of the main body of the hanging basket (1) of "clamping when lowered and loosening when hoisted".

[0045] Please see Figure 4 and Figure 6 As a technical optimization of this utility model, two fixing frames (6) are symmetrically arranged. One end of the fixing frame (6) is slidably engaged with the first sliding bar (2). A first pulley (7) that is in contact with the first sliding bar (2) is rotatably connected to the fixing frame (6).

[0046] In this implementation, two fixed frames (6) are arranged symmetrically on the left and right sides of the main body (1) of the hanging basket. Their front ends are slidably engaged with the outer edge of the first sliding bar (2) in the form of a groove, forming a guide pair that can move up and down relative to each other. At the same time, each fixed frame (6) has a first pulley (7) horizontally installed on the inner side of its front end through a pin. The outer circumferential surface of the first pulley (7) keeps rolling contact with the first sliding bar (2). When the main body (1) of the hanging basket descends due to its own weight, the first sliding bar (2) moves downward relative to the fixed frame (6), and the first pulley (7) rolls smoothly. This not only transforms sliding friction into rolling friction to reduce resistance, but also suppresses the lateral sway of the fixed frame (6) through the clamping action of the double pulleys, thereby ensuring that the first rack (4) and the gear 12 maintain a stable and accurate meshing relationship throughout the entire descent process, making the synchronous action of the clamping components more stable and reliable.

[0047] Please see Figure 6 As a technical optimization of this utility model, multiple sets of second pulleys (9) are rotatably connected at equal intervals on the fixed plate (8).

[0048] In this implementation, the fixing plate (8) has several sets of shaft holes at equal intervals along its length. Each set of shaft holes is rotatably connected to a second pulley (9) by a pin. The second pulley (9) is used to connect with the clamping assembly to reduce the sliding resistance of the clamping assembly and improve the sliding effect.

[0049] Please see Figure 7As a technical optimization of this utility model, the linkage component includes:

[0050] A fixing rod (10) is fixed between two fixing frames (6), and two second rolling balls (11) are symmetrically installed on the fixing rod (10).

[0051] Gear (12), which rotates symmetrically at both ends of the fixed rod (10), meshes with the first rack (4).

[0052] In this implementation, the fixed rod (10) is horizontally fixed between the two fixed frames (6), and the two ends of the fixed rod (11) are symmetrically installed with second rolling balls, so that the fixed rod (10) maintains rolling contact with the anti-collision wall of the bridge and reduces sliding friction. The gears (12) are respectively installed at both ends of the fixed rod (10) through bearings. The teeth of the gears are precisely meshed with the first rack (4) fixed outside the second sliding bar (3). When the main body of the hanging basket (1) drops due to its own weight, the first rack (4) generates a vertical displacement relative to the gear (12), driving the gear (12) to rotate synchronously, thereby converting the vertical motion into linkage output, providing continuous and stable power for the lateral retraction of the clamping component, ensuring that the clamping force increases linearly with the weight of the hanging basket, and the whole process does not require external force intervention, nor will it generate impact noise due to excessive tooth gap.

[0053] Please see Figure 8 As a technical optimization of this utility model, the clamping component includes:

[0054] The plug rod (13) slides on the second pulley (9) and the plug rod (13) is provided with a plug groove (14) that is adapted to slide on the second pulley (9).

[0055] The second rack (15) is fixed at one end of the lower side of the plug rod (13) and meshes with the gear (12). One end of the plug rod (13) is fixed with an abutment structure.

[0056] The resisting structure includes:

[0057] A clamping frame (16) is fixedly connected to the plug rod (13), and a fourth rolling ball (18) is symmetrically installed on the clamping frame (16).

[0058] The third rolling ball (17) is symmetrically installed at the connection between the clamping frame (16) and the plug rod (13).

[0059] Two first rolling balls (5) are symmetrically installed on the main body (1) of the hanging basket.

[0060] In this implementation, the plug rod (13) straddles the rim of the second pulley (9) through the plug groove (14), so that the plug rod (13) as a whole obtains a low-friction lateral sliding channel; when the gear (12) is driven to rotate by the first rack (4), the second rack (15) meshing with it immediately drives the plug rod (13) to move smoothly forward and backward along the second pulley (9), thereby converting the vertical weight of the hanging basket body (1) into the horizontal clamping force of the clamping frame (16) on the side of the crash barrier;

[0061] The clamping frame (16) is rigidly connected to the plug rod (13). The fourth rolling ball (18) is symmetrically embedded on the side facing the wall. After contacting the wall, it forms a rolling pair, which reduces the pushing resistance and avoids scratching the concrete surface. The third rolling ball (17) is located at the corner where the clamping frame (16) and the plug rod (13) are connected. It can roll along the top edge of the wall during the clamping process, which plays the role of guiding and distributing pressure evenly. At the same time, the two first rolling balls (5) symmetrically arranged on the inner side of the hanging basket body (1) roll and fit against the other side of the anti-collision wall, forming a four-point clamping rolling closed loop. This allows the whole device to maintain low wear and low noise, and the clamping force can automatically increase or decrease with the weight of the hanging basket, regardless of whether it moves longitudinally along the wall or is stationary. This completely eliminates the risk of shaking caused by excessive gaps in traditional hanging baskets.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
