Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a front support cable-stayed basket walking system. Background Technology

[0002] In the field of modern bridge construction, segmental cantilever construction of the concrete main girder of cable-stayed bridges is a common and efficient construction method. However, existing hanging basket traveling systems still have many problems in application, affecting construction efficiency and safety.

[0003] Traditional front-support cable-stayed formwork systems typically rely on manual or mechanical operation. However, uneven traction force distribution and difficulty in synchronizing control during movement can easily lead to the formwork getting stuck, deviating, or tilting, thus affecting construction progress and safety. Furthermore, the complex structure of traditional systems involves multiple independent control units, resulting in cumbersome operation procedures, long debugging times, and high technical requirements for construction personnel, increasing construction difficulty and labor costs. In addition, existing technologies have poor adaptability to complex construction environments. For example, in conditions of strong winds, complex terrain, or significant changes in stress conditions, the stability and accuracy of the formwork's movement are difficult to guarantee, easily leading to uneven structural stress, deformation, or damage, affecting construction quality and safety. Simultaneously, the long stress path and low structural stability can create potential safety hazards during construction. Utility Model Content

[0004] The purpose of this invention is to provide a front-support cable-stayed basket walking system to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front-support cable-stayed basket walking system, comprising:

[0006] Main beam ribs;

[0007] The hanging basket body is mounted on the main beam rib;

[0008] The travel track is installed on the hanging basket body;

[0009] A hydraulic mechanism is connected to the basket body, and the hydraulic mechanism extends and retracts synchronously to drive the basket body forward.

[0010] Preferably, the bottom of the walking track is leveled with a layer of sand.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0017] This front-support cable-stayed basket traveling system uses a hydraulic mechanism to drive the basket body forward synchronously, avoiding the asynchrony problems caused by traditional manual or mechanical operations. This effectively reduces track jamming, offset, or tilting during basket travel, improving construction accuracy and efficiency. The stability of the track installation is ensured by leveling the bottom of the traveling track with a sand layer and fixing anchor bolts. Simultaneously, anti-roll wheels are installed on the rear crossbeam and main longitudinal beam, rolling on the bottom surface of the main beam ribs, serving as a tail support point. This effectively overcomes the forward tilting moment during basket travel, improving the overall stability and safety of the system. This invention incorporates a longitudinal propulsion mechanism, C-shaped hanging legs, and traveling slippers on the basket body. By connecting the jacks to the longitudinal propulsion mechanism, the travel of the hanging basket can be precisely controlled, reducing reliance on the technical skills of construction personnel, lowering operational difficulty, and optimizing the construction process.

[0022] 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.

[0023] like Figures 1-3 As shown, a front-support cable-stayed formwork traveling system includes: a main beam rib 11; a formwork body 10 mounted on the main beam rib 11; a traveling track 1 mounted on the formwork body 10; and a hydraulic mechanism 9 connected to the formwork body 10, the hydraulic mechanism 9 synchronously driving the formwork body 10 forward through extension and retraction. This front-support cable-stayed formwork traveling system is mainly used for moving the formwork during bridge construction. The formwork body 10 is installed on the main beam rib 11 and provides stable sliding support through the traveling track 1. The hydraulic mechanism 9 is connected to the formwork body 10, and its extension and retraction synchronously drive the formwork body 10 forward along the traveling track 1. Through the hydraulic control system, the action of the hydraulic mechanism 9 is precisely adjusted, thereby achieving smooth and controllable advancement of the formwork body 10, ensuring the safety and efficiency of the construction process. This system uses the hydraulic mechanism 9 for drive, which enables synchronous and smooth movement of the formwork body 10, avoiding the impact load that may be generated by traditional mechanical drive methods, and improving the safety and service life of the system. Meanwhile, the design of the traveling track 1 provides better guidance, reduces the risk of deviation during operation, and improves construction accuracy. Furthermore, the system has a compact structure, occupies little space, is easy to install and disassemble, and is suitable for various bridge construction environments.

[0024] In other embodiments, the traveling track 1 can be driven by rollers or rack and pinion to adapt to different construction needs. The hydraulic mechanism 9 can be replaced by an electric actuator or a pneumatic drive to meet the power requirements of specific occasions. In addition, the material of the hanging basket body 10 can be high-strength aluminum alloy or composite material to further reduce its weight and improve construction convenience.

[0025] The bottom of the traveling track 1 is leveled using a sand layer 6. The sand layer 6 provides a flat supporting foundation. The sand layer 6 effectively adjusts the flatness of the track, reducing track tilting or localized stress concentration caused by uneven foundation conditions. By adjusting the thickness and density of the sand layer 6 during construction, the stability of the traveling track 1 can be ensured, improving the smoothness of the hanging basket body 10's movement. Simultaneously, the sand layer 6 can absorb vibrations from the traveling track 1 during operation to a certain extent, reducing system operating noise and improving the safety and comfort of the construction environment. Using a sand layer 6 to level the traveling track 1 enhances the system's stability and reliability, preventing track deformation or uneven stress caused by uneven foundation conditions. Furthermore, the sand layer 6 is simple to lay, convenient to construct, and adaptable to different construction site foundation conditions, reducing the need for foundation hardening treatment and thus lowering construction costs. This solution also reduces direct contact between the track structure and the ground, lowering the risk of damage caused by friction or excessive localized stress, and extending the system's service life.

[0026] In other embodiments, the sand layer 6 can be replaced by a concrete leveling layer or a steel plate paving scheme to adapt to different construction needs. If the foundation conditions at the construction site are good, adjusting pads or adjustable support structures can also be used to ensure the levelness of the walking track 1. In addition, the material of the sand layer 6 can be selected from sand and gravel mixtures of different particle sizes according to site requirements to optimize the leveling effect and load-bearing capacity.

[0027] The hanging basket body 10 is equipped with anti-roll wheels 5, which are arranged on the rear crossbeam and the corresponding main longitudinal beam. The anti-roll wheels 5 are installed at corresponding positions on the rear crossbeam and main longitudinal beam of the hanging basket body 10. Their main function is to provide additional anti-buoyancy control, ensuring that the hanging basket body 10 does not lift or tilt due to external forces or load changes while running on the travel track 1. The anti-roll wheels 5 are close to the upper or side of the travel track 1, forming a stable constraint structure, keeping the hanging basket body 10 balanced during forward movement and avoiding instability caused by center of gravity shift. With the anti-roll wheels 5 installed, the hanging basket body 10 maintains better operational stability during forward movement, reducing swaying caused by wind loads, construction loads, or uneven stress. Simultaneously, the arrangement of the anti-roll wheels 5 optimizes the torsional stiffness of the hanging basket system, enabling it to maintain a precise trajectory even in complex construction environments, improving construction safety and operational accuracy. Furthermore, this structure is simple and easy to install, does not add extra burden to the system, and helps improve the overall durability of the hanging basket body 10.

[0028] In other embodiments, the anti-roller 5 can be of an adjustable structure to adapt to different track sizes and operating requirements. Furthermore, the installation position of the anti-roller 5 can be adjusted according to construction needs, such as adding additional anti-roller sets to improve anti-buoyancy. In addition, the anti-roller 5 can be made of high-strength, wear-resistant rubber-coated rollers or ball bearing rollers to reduce friction loss and improve service life and operational smoothness.

[0029] The hydraulic mechanism 9 includes a jack 3, which is connected to the hanging basket body 10. The hydraulic mechanism 9 uses the jack 3 as the main actuator, and the extension and retraction of the jack 3 moves or lifts the hanging basket body 10. The jack 3 is installed at key load-bearing parts of the hanging basket body 10. When the hydraulic system applies pressure, the jack 3 extends, pushing the hanging basket body 10 forward along the travel track 1; when the hydraulic system retracts the pressure, the jack 3 retracts, stopping or adjusting the position of the hanging basket body 10. By precisely controlling the working stroke of the jack 3, the hanging basket body 10 can maintain stable force during construction, improving operational safety and accuracy. This system uses the jack 3 as the actuator of the hydraulic mechanism 9. Compared to traditional mechanical drive methods, the hydraulic drive of the jack 3 has higher control precision and smoother power output, effectively reducing impact loads and extending equipment lifespan. Simultaneously, the self-locking characteristic of the hydraulic system enhances the safety of the hanging basket body 10, preventing accidental slippage. In addition, the design is compact, occupies little space, is easy to install and maintain, and improves the flexibility and adaptability of the construction site.

[0030] In other embodiments, jack 3 can be replaced with an electric actuator or a pneumatic cylinder to adapt to different construction needs. If higher load capacity is required, a multi-stage telescopic jack or a synchronous hydraulic system can be used to ensure smooth advancement with a larger stroke. In addition, the installation method of jack 3 can be optimized according to the construction environment, for example, by using a rotating support or sliding rail structure to improve movement flexibility and reduce the impact of force concentration on the structure.

[0031] The hanging basket body 10 is equipped with a longitudinal propulsion mechanism 4 and C-shaped hanging legs 8, and the jack 3 is connected to the longitudinal propulsion mechanism 4. The hanging basket body 10 achieves stable propulsion along the travel track 1 through the longitudinal propulsion mechanism 4. The jack 3, as a power source, is connected to the longitudinal propulsion mechanism 4 and provides thrust to drive the hanging basket body 10 forward. The C-shaped hanging legs 8 enhance the load-bearing capacity of the hanging basket body 10 and provide a stable support structure, ensuring the stability of the hanging basket body 10 during construction. The longitudinal propulsion mechanism 4 can precisely control the movement step of the hanging basket body 10, enabling it to adapt to different construction needs and improve construction efficiency and operational accuracy. This system achieves efficient and stable movement of the hanging basket body 10 through the synergistic action of the longitudinal propulsion mechanism 4 and the C-shaped hanging legs 8. The introduction of the longitudinal propulsion mechanism 4 makes the propulsion process of the hanging basket body 10 smoother and more controllable, avoiding deviation or swaying caused by the action of a single jack 3, and improving the safety and reliability of system operation. Meanwhile, the C-type hanging leg 8 provides additional load-bearing support, helping to reduce stress concentration on the hanging basket structure and improve overall durability. Furthermore, the system's compact structure makes it suitable for various bridge construction environments, improving construction efficiency and reducing maintenance costs.

[0032] In other embodiments, the longitudinal propulsion mechanism 4 can be driven by a rack and pinion, electric rollers, or a hydraulic motor to meet different construction needs. The C-type support leg 8 can be made of high-strength steel or aluminum alloy to optimize weight and load-bearing capacity. In addition, the jack 3 can use a multi-stage hydraulic cylinder or a synchronous telescopic mechanism to ensure a wider range of propulsion capabilities and more precise control.

[0033] A traveling slipper 2 is installed on the C-shaped hanging leg 8. The traveling slipper 2, mounted on the C-shaped hanging leg 8, reduces the frictional resistance of the basket body 10 on the traveling track 1, improving its smoothness and stability of movement. The traveling slipper 2 forms a sliding contact with the traveling track 1, allowing the basket body 10 to move forward more smoothly under the drive of the longitudinal propulsion mechanism 4 and the jack 3. Simultaneously, the traveling slipper 2 effectively distributes the force on the basket body 10, reducing localized wear on the track and improving the system's durability. By installing the traveling slipper 2 on the C-shaped hanging leg 8, this system can further optimize the traveling performance of the basket body 10, reduce running resistance, and improve the accuracy and stability of construction movement. The design of the traveling slipper 2 effectively reduces wear on the track 1, extends its service life, and reduces maintenance costs. Furthermore, this structure can adapt to different types of traveling tracks 1, enhancing the system's adaptability and ensuring stable operation even in complex construction environments.

[0034] In other embodiments, the travel shoe 2 can be made of wear-resistant nylon, polytetrafluoroethylene, or high-strength alloy materials to further reduce friction and improve durability. If higher load-bearing capacity is required, rolling bearings or sliding rails can be added to the travel shoe 2 to reduce sliding friction and improve operating efficiency. Furthermore, the shape and installation method of the travel shoe 2 can be optimized according to different track structures; for example, an adjustable shoe design can be adopted to adapt to different track widths and construction requirements.

[0035] Anchor bolts 7 are fixed to the bottom of the traveling track 1. The anchor bolts 7 securely fix the traveling track 1 to the construction base surface, ensuring that the track will not shift or loosen during the movement of the hanging basket body 10. During construction, fixing holes are first drilled at the installation location of the track 1, and then the track 1 is fastened to the foundation or embedded parts using the anchor bolts 7. In this way, the traveling track 1 can withstand the load of the hanging basket body 10 and the horizontal thrust generated during operation, preventing track deviation due to inertia or vibration, and improving the stability and safety of the system. By fixing the anchor bolts 7 to the bottom of the traveling track 1, this system can effectively improve the stability of the track, prevent the track from shifting or warping under stress, and ensure the traveling accuracy of the hanging basket body 10. At the same time, this fixing method can enhance the load-bearing capacity of the track, reduce stress concentration between the track and the foundation, and improve overall durability. Furthermore, the anchor bolts 7 are easy to install, suitable for various construction sites, and the fixing method can be adjusted as needed to enhance the applicability of the system.

[0036] In other embodiments, the anchor bolts 7 can be replaced with chemical anchors or expansion bolts to improve fixing strength and adapt to foundation structures of different materials. If the construction environment permits, pre-embedded bolts can also be used to allow the running track 1 to be directly installed on the concrete foundation, further improving stability. In addition, to enhance seismic resistance, shock-absorbing pads can be installed between the anchor bolts 7 and the track 1 to improve the system's impact resistance and extend its service life.
