Description

Technical Field

[0001] This application relates to the field of construction technology of hanging basket bridge construction, and in particular to a hoisting structure and hanging basket hoisting system on a hanging basket. Background Technology

[0002] In cantilever bridge construction, the hanging basket method is the core technology for the segmental forming of large-span beams. This technology uses the hanging basket as a mobile working platform, and through a cyclical process of "symmetrical pouring - tensioning and anchoring - moving the hanging basket forward," the beam cantilever extends from block 0 to both sides. The hanging basket typically consists of a main truss, formwork system, anchoring device, and traveling mechanism. It can bear the weight of the newly poured concrete and construction loads, and transfers the load to the already poured beam segments through the rear anchoring system. During construction, block 0 is poured first on the pier top and the hanging basket is assembled. Then, block 1 and subsequent segments are poured segment by segment using the hanging basket as support. After each segment of concrete reaches its strength, the prestressing tendons are tensioned, and then the hanging basket is moved forward to the next pouring position through the traveling system.

[0003] In existing technologies, material hoisting in hanging basket construction mainly relies on the following two methods: The first is to use a large tower crane for hoisting. The large tower crane is set up at the No. 0 block of the bridge, and the material is transported using the crane's boom. However, the hoisting range of the large tower crane is limited by the length of the boom, the tower crane itself cannot move, and the lifting and luffing speeds are slow, making it difficult to match the pace of the hanging basket construction. This is especially problematic in narrow bridge decks or complex working conditions, resulting in inconvenient operation and low efficiency. The second method is to use the truss rods of the hanging basket itself as rails and set up a sliding sling trolley for hoisting. This method uses a truss rod of the hanging basket as a rail, allowing the sling trolley to slide along the length of the truss rod, achieving localized material transport at the front working surface of the hanging basket. Its advantage is that no additional load-bearing structure is required, and the existing rods of the hanging basket can bear the hoisting load, resulting in a simple structure and low cost. However, this method has a very limited hoisting range, only allowing hoisting within the length of the truss rods. Utility Model Content

[0004] This application provides a hoisting structure for a hanging basket, which solves the problems of inconvenient hoisting and limited hoisting range in the prior art, and achieves the effect of convenient hoisting during the construction of the hanging basket.

[0005] This application also provides a hanging basket hoisting system.

[0006] According to the first aspect of the present application, the hoisting structure on the hanging basket includes a truss module, and the hoisting structure includes a support column assembly, a cantilever, a hoisting vehicle, and a counterweight module.

[0007] One end of the support column assembly is used to be installed to the truss module, and the other end is connected to one end of the cantilever. The cantilever is configured to rotate about the support column assembly as a pivot. The crane is movably mounted on the cantilever.

[0008] The counterweight module is connected to the cantilever, and the counterweight module and the cantilever are located on both sides of the support column assembly.

[0009] According to one embodiment of this application, the counterweight module includes a counterweight assembly and a connecting rod, one end of the connecting rod is connected to the cantilever, and the other end of the connecting rod is fixed to the counterweight assembly.

[0010] According to one embodiment of this application, the counterweight assembly includes a first counterweight block located on the extension line of the cantilever; or, the counterweight assembly includes multiple counterweight blocks, the centers of gravity of the multiple counterweight blocks being located on the extension line of the cantilever.

[0011] According to one embodiment of this application, the support column assembly includes a column assembly and a connecting flange plate. The connecting flange plate is mounted on the truss module and is fixedly connected to the lower end of the column assembly. The upper end of the column assembly is connected to one end of the cantilever.

[0012] According to one embodiment of this application, the column assembly includes a first column and a second column;

[0013] A hydraulic cylinder is installed inside the first column, and a piston rod is connected to the hydraulic cylinder. The piston rod is connected to the second column, and the hydraulic cylinder drives the piston rod to raise and lower the second column to adjust the height of the column assembly; or...

[0014] The first column is a hollow column with internal threads on its inner surface, and the second column has external threads on its outer surface. The first column and the second column are threaded together so that the height of the column assembly is adjustable.

[0015] According to one embodiment of this application, the top of the support column assembly is higher than the connection point between the cantilever and the support column assembly;

[0016] The hoisting structure also includes a connecting wire rope, one end of which is connected to the top of the support column assembly, and the other end is connected to the free end of the cantilever.

[0017] According to one embodiment of this application, the cantilever length is 4m to 10m.

[0018] According to one embodiment of this application, the hoisting structure on the hanging basket also includes an operating platform located at the upper end of the support column assembly.

[0019] According to the second aspect of the present application, the hanging basket hoisting system includes a plurality of the aforementioned hoisting structures on the hanging basket, with the cantilever of adjacent hoisting structures located at different height positions.

[0020] According to one embodiment of this application, the truss module includes a beam assembly and a plurality of planar trusses, with adjacent planar trusses connected by the beam assembly to form a three-dimensional truss module; the planar trusses include main trusses, and the beam assembly includes a front upper beam;

[0021] One end of the support column assembly is installed on the main truss or the front upper crossbeam.

[0022] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0023] Unlike existing methods that use large tower cranes or sliding-rail trolleys mounted on truss members, this application employs a hoisting structure on the truss module. This "cantilever + hoisting vehicle" approach enables the partial hoisting of materials required for the front-end construction of the hanging basket. The hoisting structure, smaller than the large tower crane, facilitates quick and easy hoisting. Located on the truss module of the hanging basket, it moves with the basket, ensuring it can always perform hoisting operations at the front end without exceeding its hoisting range. The cantilever and hoisting vehicle design eliminates limitations imposed by truss member length, increasing the hoisting range and enhancing practicality. A counterweight module connected to the cantilever significantly improves structural stability through a torque balancing mechanism. The counterweight module counteracts the overturning moment generated by the load at the free end of the cantilever (the weight of the hoisted material) with its reverse torque, reducing the anchoring force required at the rear of the main truss and minimizing the impact on the truss module.

[0024] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] According to the first aspect of the embodiment of the hanging basket, the hoisting structure 1 is as follows: Figures 1 to 9As shown, the hanging basket includes a truss module 2, and the hoisting structure 1 includes a support column assembly 11, a cantilever 12, a hoisting vehicle 13, and a counterweight module 14. One end of the support column assembly 11 is used to install to the truss module 2, and the other end is connected to one end of the cantilever 12. The cantilever 12 is configured to rotate around the support column assembly 11 as a pivot. The hoisting vehicle 13 is movably installed on the cantilever 12. The counterweight module 14 is connected to the cantilever 12, and the counterweight module 14 and the cantilever 12 are located on both sides of the support column assembly 11.

[0043] The hanging basket is installed at position 3 on the web of the beam.

[0044] The length of cantilever 12 can be selected based on the longest casting segment.

[0045] The crane 13 can be equipped with pulleys, and the cantilever 12 is equipped with a slide rail. The pulleys are slidably installed in the slide rail and will not come out of the slide rail. The crane 13 is equipped with a chain and a hook. The hook is located below the chain, and the length of the chain is adjustable so that the height of the hook is adjustable, which facilitates the lifting of materials such as jacks and steel bars.

[0046] Of course, a pallet or other container can also be used under the crane 13, that is, a pallet or other container is fixed under the chain to suit different types of material lifting.

[0047] The hoisting vehicle 13 can be equipped with a drive mechanism 17, which drives the hoisting vehicle 13 to reciprocate along the length of the cantilever 12. The drive mechanism 17 can be a drive motor, and the drive motor can be protected by an outer casing. The hoisting vehicle 13 can be controlled by wired or wireless means. The hoisting vehicle 13 can also be protected by an outer casing to prevent damage from collisions with materials or other equipment.

[0048] The cantilever 12 is connected to a counterweight module 14, which significantly improves structural stability through a torque balancing mechanism. The counterweight module 14 counteracts the overturning moment generated by the load (weight of the hoisted material) at the free end of the cantilever 12 through a reverse torque, reducing the anchoring force requirement at the rear end of the main truss and minimizing the impact on the truss module 2.

[0049] By dynamically matching the counterweight mass with the load of the cantilever 12, the weight of the counterweight module 14 can be dynamically adjusted to accommodate the lifting of materials of different quantities and weights, which is convenient and reliable. Of course, in practical applications, a fixed weight counterweight module 14 can also be used without adjusting its weight, so that the truss module 2 bears a smaller torque and the lifting speed is accelerated.

[0050] The mechanical balance is optimized through the cooperation of cantilever 12 and counterweight module 14, fundamentally solving the overturning risk and deformation control problems during cantilever 12 construction. The counterweight module 14 improves the balance of the lifting structure 1, effectively increasing the length of cantilever 12 and expanding the lifting range.

[0051] Unlike existing methods that use large tower cranes or sliding rail trolleys mounted on truss members, this application uses a lifting structure 1 on the truss module 2. This structure, consisting of a cantilever 12 and a lifting vehicle, enables the partial lifting of materials required for the front-end construction of the hanging basket. The lifting structure 1, smaller than the large tower crane, facilitates quick and easy lifting. Furthermore, being mounted on the truss module 2 of the hanging basket, it moves with the basket, ensuring that it can always perform lifting operations at the front end of the basket without exceeding its lifting range. The lifting structure 1, equipped with a cantilever 12 and a lifting vehicle, is not limited by the length of the truss members, thus increasing the lifting range and demonstrating strong practicality.

[0052] According to one embodiment of this application, the counterweight module includes a counterweight assembly and a connecting rod 142. One end of the connecting rod 142 is connected to the cantilever, and the other end of the connecting rod 142 is fixed with the counterweight assembly.

[0053] According to one embodiment of this application, the counterweight assembly includes a first counterweight block 141, which is located on the extension line of the cantilever 12, such as... Figure 6 As shown; or, the counterweight assembly includes multiple counterweight blocks, the center of gravity of which is located on the extension line of the cantilever 12 (not shown in the figure).

[0054] In practical applications, the position of the counterweight can be higher or lower than the extension line of the cantilever 12 to a certain extent, so as to offset all or part of the torque of the hoisted material.

[0055] In addition, the counterweight module 14 may also include a slide rail, allowing the counterweight block to slide on the slide rail and stop at a set position. For each lifting of materials of different weights, the distance between the counterweight block and the fulcrum (the connection point of the slide rail of the counterweight module 14, the support column assembly 11, and the cantilever 12) is adjusted to enable the counterweight module 14 to play a better balancing role.

[0056] According to one embodiment of this application, such as Figures 1 to 3 As shown, the support column assembly 11 includes a column assembly 111 and a connecting flange plate 112. The connecting flange plate 112 is installed on the truss module 2 and is fixedly connected to the lower end of the column assembly 111. The upper end of the column assembly 111 is connected to one end of the cantilever 12.

[0057] The connecting flange plate 112 can be rigidly connected to the truss module 2 via bolts, and the column assembly 111 vertically transfers the load of the cantilever 12 (the weight of the hoisted material) to the main truss structure. The standardized design of the connecting flange plate 112 (bolt hole spacing tolerance ≤ 0.5mm) supports the rapid positioning of the column assembly 111, resulting in short installation time. It is also detachable and reusable, adapting to the construction process of moving the hanging basket forward segment by segment.

[0058] Of course, in some cases, the connecting flange plate 112 and the truss module 2 can also be fixed by welding or other methods.

[0059] According to one embodiment of this application, the column assembly 111 includes a first column and a second column; a hydraulic cylinder is provided inside the first column, the hydraulic cylinder is connected to a piston rod, the piston rod is connected to the second column, and the hydraulic cylinder drives the piston rod to push the second column up and down to adjust the height of the column assembly 111 (not shown in the figure); or, the first column is a hollow column and the inner surface is provided with internal threads, the outer surface of the second column is provided with external threads, and the first column and the second column are threadedly connected to make the height of the column assembly 111 adjustable (not shown in the figure).

[0060] The column assembly 111 is height-adjustable via hydraulic drive or threaded connection, facilitating the hoisting of different types of materials.

[0061] In the hydraulically driven structure, the piston rod built into the hydraulic cylinder is rigidly connected to the second column. Power can be provided by a hydraulic pump station, enabling stepless adjustment of the column height and meeting the dynamic adjustment requirements of the cantilever height during hanging basket construction. The hydraulically driven structure has a high degree of automation, with a single column lifting speed of up to 50mm / min. Combined with a synchronous control system, it can achieve coordinated leveling of multiple columns, significantly improving construction efficiency, and is especially suitable for high-precision alignment control of long-span bridges.

[0062] The threaded connection structure utilizes the engagement of the internal thread of the first column and the external thread of the second column to convert rotational motion into linear motion, achieving precise height adjustment (adjustment accuracy up to ±1mm). The threaded connection method is simple in structure, low in cost, and highly reliable, requiring no additional power system. The self-locking characteristic of the threaded pair (thread helix angle ≤7°) effectively prevents column slippage under vibration conditions and can be used in conjunction with other anti-loosening structures (such as setting pin holes at preset positions) to control the height error within ±0.5mm, meeting the lifting requirements of the cantilever 12. It should be noted that during height adjustment, the cantilever 12 is in a non-working state; that is, for safety, the cantilever 12 does not lift materials during the height adjustment of the column assembly 111. During the relative rotation of the first and second columns, the cantilever 12 will rotate accordingly. After the relative positions of the first and second columns are adjusted, the cantilever 12 can be rotated to the area where the material to be lifted will be placed.

[0063] According to one embodiment of this application, such as Figure 2 and Figure 3 As shown, the top of the support column assembly 11 is higher than the connection point between the cantilever 12 and the support column assembly 11; the hoisting structure 1 also includes a connecting wire rope 15, one end of which is connected to the top of the support column assembly 11 and the other end is connected to the free end of the cantilever 12.

[0064] The support column assembly 11, with its top higher than the connection point of the cantilever 12 and connected to the free end by a wire rope, forms a "tension-support" composite force system. The height difference at the top of the support column causes the wire rope to generate an inclined tension, producing an upward vertical component force that offsets part of the load (weight of the hoisted material) at the free end of the cantilever 12, effectively reducing the bending moment at the root of the cantilever 12.

[0065] The structure optimizes the stress structure through a rigid-flexible coupling design of "rigid support column + flexible tension of steel wire rope". The steel wire rope can reduce the cross-sectional size of the support column to a certain extent and reduce the amount of material used.

[0066] When the wire rope inclined structure is used in conjunction with the counterweight module 14, the weight of the counterweight can be reduced to a certain extent, thus reducing the additional burden on the truss module 2.

[0067] In actual construction, the tension of the wire rope can be dynamically adjusted by turnbuckles or hydraulic tensioners to adapt to the variable load conditions of cantilever 12 casting.

[0068] According to one embodiment of this application, the length of the cantilever 12 is 4m to 10m.

[0069] With the counterweight module 14 in place, the length of the cantilever 12 can be set to a longer value.

[0070] According to one embodiment of this application, such as Figure 2 As shown, the hoisting structure 1 on the hanging basket also includes an operating platform 16 located at the upper end of the support column assembly 11.

[0071] The operating platform 16, located at the upper end of the support column assembly 11, significantly improves the efficiency of hanging basket construction through "expanded high-altitude working space + enhanced safety protection". Relying on the rigid support of the support column assembly 11, it provides a working surface for construction personnel to carry out inspection, maintenance or other work.

[0072] The operating platform 16 can be equipped with a 1.2m high detachable guardrail and anti-slip grid (friction coefficient ≥0.6) along its edge. Combined with the safety rope anchor points, this reduces the risk of falls from height for operators and improves safety.

[0073] The operating platform 16 and the support column assembly 11 can be an integrated design, or they can be fixed together by bolts, welding, or other means. The operating platform 16 can be made of checkered steel plate.

[0074] The hoisting structure 1 provided in this application is not only applicable to top-supported hanging baskets (diamond-shaped hanging baskets, triangular hanging baskets), but can also be applied to bottom-supported hanging baskets, with a wide range of applications and strong practicality.

[0075] According to the second aspect of the embodiment of the hanging basket hoisting system of this application, such as Figure 4 As shown, the hanging basket hoisting system includes multiple hoisting structures 1 on the aforementioned hanging baskets, and the cantilever 12 of adjacent hoisting structures 1 are located at different heights.

[0076] The hanging basket hoisting system constructs a three-dimensional, interference-free material transportation network by arranging 12 adjacent cantilever arms at different heights.

[0077] The height difference between adjacent cantilever 12 can be set to 0.5 to 1.5m, so that the running trajectory of the crane 13 is separated in the vertical direction, completely avoiding collisions during the hoisting process.

[0078] In some cases, the cantilever 12 can be configured as a length-adjustable cantilever 12.

[0079] According to one embodiment of this application, the truss module 2 includes a beam assembly and multiple planar trusses, with adjacent planar trusses connected by the beam assembly to form a three-dimensional truss module 2; the planar trusses include a main truss 21, and the beam assembly includes a front upper beam 22; one end of the support column assembly 11 is used for mounting to the main truss 21 or the front upper beam 22. Figures 3 to 5 , Figure 8 and Figure 9 In the middle, one end of the support column assembly 11 is mounted on the front upper crossbeam 22; such as Figure 6 and Figure 7 As shown, one end of the support column assembly 11 is mounted on the main truss 21.

[0080] Figure 5 The image shows the installation positions of the three hoisting structures 1, and the three corresponding circles represent the hoisting range of each hoisting structure.

[0081] When the support column assembly 11 is installed on the main truss 21, the longitudinal stiffness of the main truss 21 is used to evenly distribute the load to the entire truss module 2, which is suitable for situations where the weight of the materials being hoisted is large. When the support column assembly 11 is installed on the front upper crossbeam 22, the installation position is closer to the front end of the hanging basket, which is suitable for situations where the materials need to be placed further forward.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
