Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically a suspended platform for bridge construction. Background Technology

[0002] Suspended platforms are construction machinery used for high-altitude operations in building engineering. Based on materials, they can be divided into steel-framed electric suspended platforms and aluminum alloy electric suspended platforms. Based on the power source for lifting, they can be divided into manual suspended platforms and electric suspended platforms. They are characterized by their ability to replace traditional scaffolding, reduce labor intensity, improve work efficiency, and be reusable.

[0003] During bridge maintenance and construction, workers often use suspended platforms to move to the corresponding locations on the bridge for work. However, the complex environment of bridges, the influence of wind, bridge vibrations, and the movement of the suspended platforms, makes them prone to swaying during use. This swaying not only threatens the safety of workers, causing dizziness and increasing the probability of accidents such as falls from heights, but also affects the accuracy and efficiency of construction, making it difficult for workers to operate tools precisely and prolonging the construction time. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge construction suspended platform that uses wind resistance plates to suppress wind vibration, plastic cylinders to provide damping, and sliders to adjust the counterweight, thereby significantly reducing the swaying of the suspended platform, improving the stability and safety of high-altitude operations, extending equipment life, and ensuring construction safety, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, a suspended platform for bridge construction is provided, including a suspended platform and slings at its top. A wind resistance plate is screwed onto the outer side of the suspended platform. A set of symmetrically arranged plastic barrels is connected to the bottom of the suspended platform by a chain, and anti-fall pockets are provided around the plastic barrels.

[0006] Furthermore, the wind resistance plate includes a plate made of rubber and in the shape of a plate. The plate is connected to the suspended basket by bolts and threads. Multiple ventilation holes are arranged in an array along the thickness direction on the end face of the plate.

[0007] Furthermore, the fall arrestor includes multiple elastic traction cables hinged to the bottom of the basket, with a fall arrestor plate at the bottom of the elastic traction cables.

[0008] Furthermore, the suspended platform includes a base plate, on the top of which a cross-shaped groove is provided. The groove has a boss-shaped cross section and also includes a slider that slides along the groove.

[0009] Furthermore, the slider is cylindrical and has a boss-shaped cross-section along the axis. A hook is provided at the top of the slider, and a roller groove is provided along the outer side of the slider. The cross-section of the roller groove is U-shaped, and multiple rollers are arranged circumferentially along the outer side of the roller groove.

[0010] This invention has the following advantages over existing technologies: By dispersing wind pressure through the ventilation holes of the wind-resistant plate, consuming energy through the liquid damping of the plastic cylinder, and protecting against falls through the elastic buffer of the fall arrestor, the wind resistance of the suspended platform is enhanced, thereby improving construction efficiency and reducing accident risks, achieving safe and efficient construction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one implementation, such as Figure 1 The diagram shows a suspended platform for bridge construction, comprising a platform 1 and slings 2 at its top. A wind-resistant plate 3 is screwed onto the outer side of the platform 1. A set of symmetrically arranged plastic cylinders 4 are connected to the bottom of the platform 1 via chains 401. Fall protection pockets 5 are provided around the plastic cylinders 4. In this application, "multiple" refers to at least two.

[0019] In this embodiment, the suspended platform 1 provides a working platform for construction workers. The slings 2 are fixed to the top of the guardrails on both sides of the suspended platform 1 and are used to connect to the external lifting mechanism. The wind resistance plate 3 screwed to the outside of the suspended platform 1 is used to reduce the swaying amplitude of the suspended platform 1 in strong wind environment and improve the stability of operation.

[0020] Two plastic cylinders 4 are symmetrically arranged at both ends of the bottom of the suspended platform 1 along the length direction. They are used to fill counterweights. Specifically, the plastic cylinders 4 are filled with two-thirds of their cavity, leaving one-third of the cavity empty. When the suspended platform 1 is subjected to an external force and swings, the counterweights in the plastic cylinders 4 that are not full will sway due to inertia. The swaying of the counterweights will generate a counter-phase damping force to counteract the swing energy of the suspended platform 1, thereby reducing the swaying amplitude of the suspended platform 1.

[0021] Please see the appendix Figure 2 As shown, the wind resistance plate 3 includes a plate body 301 made of rubber and in the shape of a plate. The plate body 301 is threadedly connected to the hanging basket 1 by bolts 303. Multiple ventilation holes 302 arranged in an array along the thickness direction are opened on the end face of the plate body 301.

[0022] In this embodiment, the plate 301 is made of rubber and is plate-shaped. The size of the plate 301 is adapted to the size of the guardrail of the suspended basket 1. Then, the plate 301 is fixed to the outside of the guardrail of the suspended basket 1 by bolts 301 to ensure that the plate 301 and the guardrail form a stable connection relationship, avoiding loosening or falling off under strong wind ring, and also facilitating disassembly and replacement when the plate 301 is damaged.

[0023] Then, ventilation holes 302 are opened on the end face of the plate 301 with an opening ratio of about 30%, which provide a flow channel for airflow, reduce the wind resistance of the plate 301, and generate vortex shedding at the ventilation holes 302, thereby destroying the resonant frequency and reducing the vibration caused by wind. At the same time, the array of ventilation holes 302 can make the airflow evenly distributed on the plate 301, avoid the local airflow being too concentrated and causing excessive local stress on the plate 301, and further enhance the structural stability of the wind resistance plate 3.

[0024] The combined effect of the wind resistance plate 3 and the liquid damping function of the plastic cylinder 4 means that the wind resistance plate 3 suppresses the swaying caused by the wind, and then the liquid inside the plastic cylinder 4 consumes the residual oscillation energy through phase difference damping. The two work together to greatly reduce the swaying amplitude of the suspended platform 1 and significantly improve the stability of high-altitude operations.

[0025] Please see the appendix Figure 3 As shown, the fall arrestor 5 includes multiple elastic traction cables 502 hinged to the bottom end of the basket 1, and a fall arrestor plate 501 is provided at the bottom end of the elastic traction cables 502.

[0026] In this embodiment, multiple elastic traction cables 502 are arranged in a ring and extend downward along the plumb line. They are then combined with anti-fall plates 501 fixed at the bottom of the elastic traction cables 502 to form a pocket shape, thereby wrapping the plastic barrel 4 to prevent the plastic barrel 4 from falling accidentally and to avoid causing safety hazards to the construction area below.

[0027] The elastic traction cable 502 is made of elastic material and can undergo tensile deformation when subjected to tension, thereby preventing the elastic traction cable 502 from breaking due to impact when the plastic barrel 4 falls onto the fall arresting plate 501. At the same time, the fall arresting plate 501 is made of rubber material and deforms when the plastic barrel 4 falls and impacts the fall arresting plate 501, thus preventing the fall arresting plate 501 from breaking and causing the plastic barrel 4 to fall.

[0028] Please see the appendix Figure 4 As shown, the suspended basket 1 includes a base plate 102, and a cross-shaped groove 101 is provided at the top of the base plate 102. The cross section of the groove 101 is in the shape of a boss. It also includes a slider 103 that slides along the groove 101.

[0029] Please see the appendix Figure 5 As shown, the slider 103 is cylindrical and has a boss-shaped cross section along the axis. A hook 104 is provided at the top of the slider 103. A roller groove 105 is provided along the outer side of the slider 103. The cross section of the roller groove 105 is U-shaped. Multiple rollers 106 are arranged circumferentially along the outer side of the roller groove 105.

[0030] In this embodiment, the base plate 102 serves as the bottom load-bearing structure of the suspended platform 1, supporting construction personnel and related tools and equipment. A cross-shaped groove 101 is provided at the top of the base plate 102. The grooves 101 are distributed intersectingly along the length and width of the base plate 102 to form a cross-shaped channel structure. The cross section of the groove 101 is boss-shaped. This shape can limit the sliding of the slider 103, preventing the slider 103 from disengaging from the groove 101 during sliding, and ensuring the stability of the slider 103's movement.

[0031] The slider 103 slides along the slide groove 101 and can move in multiple directions within the cross-shaped slide groove 101, making it easy to adjust its position according to construction needs. A hook 104 is provided at the top of the slider 103. The hook 104 is used to connect with the safety hook of the construction personnel. By connecting the construction personnel to the slider 103, the construction personnel can be used as a movable counterweight while improving the convenience of construction.

[0032] A roller groove 105 is provided on the outer side of the slider 103. The cross-section of the roller groove 105 is U-shaped, providing installation space for the roller 106. Multiple rollers 106 are arranged at intervals along the outer circumference of the roller groove 105. The rollers 106 can rotate around their own axis. When the slider 103 slides in the slide groove 101, the rollers 106 contact the inner wall of the slide groove 101 and roll, converting the sliding friction between the slider 103 and the slide groove 101 into rolling friction, which greatly reduces the friction between the two, making the slider 103 slide more smoothly and effortlessly. It is convenient for construction personnel to flexibly adjust their position as counterweight according to the needs of the operation, and at the same time, it reduces the wear of the components and extends the service life of the slider 103 and the slide groove 101.

[0033] Multiple rollers 106 are arranged circumferentially to support the slider 103 from multiple directions, ensuring that the slider 103 remains stable during sliding and preventing tilting or jamming due to uneven force. The U-shaped roller groove 105 can protect the rollers 106, preventing external debris from entering the connection between the rollers 106 and the slider 103, and ensuring the normal rotation of the rollers 106.

[0034] In general, when the suspended platform 1 is blown by strong wind, the airflow passes through the ventilation hole 302 of the wind resistance plate 3 and the vortex generated at the ventilation hole 302 falls off, destroying the resonant frequency and preventing the suspended platform 1 from synchronizing with the wind vibration frequency; at the same time, the evenly distributed holes disperse the airflow pressure, prevent local stress concentration on the plate 301, and significantly reduce the initial sway amplitude.

[0035] Then, when the vibration energy that cannot be suppressed by the wind resistance plate 3 is transmitted to the plastic cylinder 4, the liquid inside the plastic cylinder 4 lags behind the swing of the basket 1 due to inertia, forming an anti-phase impact force. This impact force is converted into heat energy by the liquid repeatedly hitting the inner wall of the cylinder 4, consuming the swing energy, and working together with the wind resistance plate 3 to achieve dual vibration reduction.

[0036] When the plastic cylinder 4 accidentally falls off, the impact force is first absorbed by the deformation energy of the rubber anti-fall plate 501, and then the elastic traction cable 502 stretches and extends to buffer the impact, providing double protection to prevent the cylinder 4 from falling into the construction area.

[0037] During construction, one of the safety hooks is connected to hook 104. When the worker's position changes, the slider can be moved through the cross-shaped groove 101 at the top of the base plate 102 to adjust the position of slider 103. Slider 103 will not detach due to the limiting effect of the boss-shaped cross section of the groove 101, and the multiple rollers 106 in the roller groove 105 on its outer side convert sliding friction into rolling friction, making slider 103 move more smoothly and effortlessly in multiple directions within the groove 101. This reduces component wear, extends service life, and allows construction workers to adjust the position as needed. At the same time, the hook 104 at the top of slider 103 is connected to the worker's safety hook, allowing the worker to use it as a movable counterweight, improving the convenience and stability of the operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
