Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction platforms, specifically a high-bolt construction sliding platform for large-span steel truss bridges. Background Technology

[0002] As is well known, long-span steel truss bridges, as an important bridge structure, are widely used in modern transportation infrastructure construction due to their large span capacity and strong load-bearing capacity. However, the construction process of such bridges is complex and requires extremely high standards, especially in the installation and tightening of high-strength bolts (high-strength bolts), which presents numerous challenges.

[0003] Installation materials (high bolts) on traditional sliding platforms are usually placed in fixed storage areas. The locations of these areas are predetermined and cannot be flexibly adjusted according to actual construction needs. Because the material storage locations are fixed, construction workers often need to make multiple trips (such as standing and squatting) between the storage area and the work area to retrieve materials, which increases workload and time costs. This repetitive labor not only reduces work efficiency but may also increase safety risks due to fatigue or negligence. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-bolt construction sliding platform for long-span steel truss bridges.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sliding platform for high-strength bolt construction of a long-span steel truss bridge, comprising a rectangular frame, a grid-like platform, an installation frame, a traveling mechanism, a high-strength bolt placement box, and an adjustment device. The grid-like platform is installed at the top of the rectangular frame. Installation frames are mounted on the four corners of the top wall of the rectangular frame via support legs. The traveling mechanism is connected to the outer wall of the installation frame. A tool placement box is slidably installed on one side wall of the installation frame. A box cover is hinged to the top of the tool placement box. The high-strength bolt placement box is installed on the top wall of the installation frame via the adjustment device. The adjustment device includes a rectangular block, a rectangular groove, a first screw, a first motor, a first movable seat, a fixed frame, a second screw, a second motor, and a second movable seat. The mounting bracket includes a movable seat and an energy storage block. A rectangular block is fixedly mounted on the top wall of the mounting frame.

A second screw is rotatably mounted within the fixed frame. A second motor is mounted on the top end of the second screw, which passes through the top wall of the fixed frame. A second movable seat is threaded onto the second screw. The side wall of the second movable seat is fixedly connected to the high-bolt placement box. The energy storage block is mounted on the end of the fixed frame away from the opening. A controller is mounted on the inner side wall of the rectangular block.

[0008] Preferably, in this invention, a solar panel is mounted on the front end face of the energy storage block via a connecting rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a high-bolt construction sliding platform for long-span steel truss bridges, which has the following beneficial effects:

[0017] This high-strength bolt construction sliding platform for long-span steel truss bridges, through its adjustable device and high-strength bolt placement box, uses a first motor and a second motor to drive horizontal and vertical movement respectively. This allows the high-strength bolt placement box to be flexibly adjusted at different construction nodes to adapt to different construction requirements, ensuring that construction personnel can easily obtain the necessary materials. The adjustable device can control the position of the high-strength bolt placement box as needed, enabling construction personnel to quickly find the required high-strength bolts, reducing the time spent searching for materials and improving work efficiency.

[0018] This high-bolt construction sliding platform for long-span steel truss bridges utilizes solar panels and support rods. The solar panels convert solar energy into electrical energy, providing power to various electrical devices on the platform (such as regulating devices and controllers), reducing dependence on the power grid or external power sources. Multiple sets of support rods are evenly distributed on the bottom wall of the rectangular frame, which can evenly distribute the weight of the grid-like treads and construction loads to each support point, avoiding local stress concentration and thus improving the structural stability of the entire platform.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4A sliding platform for high-strength bolt construction of a long-span steel truss bridge includes a rectangular frame 1, a grid-like platform 2, a mounting frame 3, a traveling mechanism 4, a high-strength bolt placement box 5, and an adjustment device. The grid-like platform 2 is mounted on the top of the rectangular frame 1. The mounting frame 3 is mounted on the four corners of the top wall of the rectangular frame 1 via support legs 6. The traveling mechanism 4 is connected to the outer side wall of the mounting frame 3. A tool placement box 7 is slidably mounted on one side wall of the inner side of the mounting frame 3. A box cover 8 is hinged to the top of the tool placement box 7. The high-strength bolt placement box 5 is mounted on the top wall of the mounting frame 3 via the adjustment device. The adjustment device includes a rectangular block 9, a rectangular groove 10, a first screw 11, a first motor 12, a first moving seat 13, a fixed frame 14, and a second screw 15. 5. A second motor 16, a second movable seat 17, and an energy storage block 18. The rectangular block 9 is fixedly mounted on the top wall of the mounting bracket 3. A rectangular groove 10 is formed in the top wall of the rectangular block 9. The first screw 11 is rotatably mounted within the rectangular groove 10. The first movable seat 13 is threaded onto the first screw 11. One end of the first screw 11 passes through the rectangular groove 10 and is mounted on the first motor 12. A side-opening fixing frame 14 is fixedly mounted on the top wall of the first movable seat 13. The second screw 15 is rotatably mounted within the fixing frame 14. The top end of the second screw 15 passes through the top wall of the fixing frame 14 and is mounted on the second motor 16. The second movable seat 17 is threaded onto the second screw 15. The side wall of the moving seat 17 is fixedly connected to the high-strength bolt placement box 5. The energy storage block 18 is installed at the end of the fixed frame 14 away from the opening. The controller 19 is installed on the inner side wall of the rectangular block 9. In this embodiment, during use, the platform moves the entire sliding platform along the bridge axis to the designated construction position via the walking mechanism 4, reaching each node where high-strength bolt construction is required (the structure and working principle of the walking mechanism 4 are well-known to the technical personnel and will not be described in detail here). After the workers carry the necessary tools and other connecting tools onto the grid-type pedal 2, they can place the tools in the tool placement box. When needed, the required high-strength bolt tightening tools (such as electric or pneumatic wrenches) and other auxiliary equipment are taken out from the tool placement box 7. The high-strength bolts to be used are placed in the bolt placement box 5. The controller 19 starts the first motor 12, driving the first screw 11 to rotate, causing the first moving seat 13 to move horizontally along the rectangular groove 10. When the first moving seat 13 reaches the predetermined position, the second motor 16 is started, driving the second screw 15 to rotate, causing the second moving seat 17 to move vertically, thereby adjusting the height and position of the high-strength bolt placement box 5. The energy storage block 18 provides power to the first motor 12, the second motor 16, and the controller 19. The adjustment device allows the high-strength bolt placement box 5 to be flexibly adjusted in both horizontal and vertical directions to adapt to different construction positions, ensuring that construction personnel can easily obtain the required materials. Then, the construction personnel remove the high-strength bolts from the high-strength bolt placement box 5 at the target location (as shown in the attached figure).A cover plate is slidably installed on the high-strength bolt placement box 5 (to seal the high-strength bolts when not in use). Then, install and tighten according to design requirements.

[0026] Preferably, in this embodiment, a solar panel 20 is installed on the front end face of the energy storage block 18 via a connecting rod. The solar panel 20 can convert solar energy into electrical energy to provide power for various electrical devices (regulators and controllers 19) on the platform. This reduces the dependence on the power grid or external power source, enabling the platform to work independently away from the power source.

[0027] Preferably, in this embodiment, multiple sets of support rods 21 are evenly arranged laterally on the bottom wall of the rectangular frame 1. The multiple sets of support rods 21 are evenly distributed on the bottom wall of the rectangular frame 1, which can evenly distribute the weight of the platform and the construction load to each support point, avoid local stress concentration, and thus improve the structural stability of the entire platform. In high-altitude operations, wind force is an important influencing factor. The evenly arranged support rods 21 can provide better wind resistance, reduce the swaying of the platform under strong winds, and ensure the safety of construction personnel.

[0028] Preferably, in this embodiment, the controller 19 is equipped with multiple sets of control buttons 22 and switch buttons 23. The multiple sets of control buttons 22 and switch buttons 23 are integrated on one controller 19, which allows construction personnel to centrally control various functions of the platform from one location, reducing the time spent on frequent movement and searching for control devices, and improving work efficiency. Through reasonable layout and labeling, each button and switch can correspond to a specific function, adjusting the up, down, left, and right movement of the device and adjusting the switch of the device. This intuitive operation method reduces the risk of misoperation and enables construction personnel to get started quickly.

[0029] Preferably, in this embodiment, a rain shield 24 is installed above the controller 19. The rain shield 24 can effectively block rainwater, snow water and other liquids from falling directly onto the controller 19, prevent moisture from entering the internal electronic components, and reduce the risk of short circuits and damage caused by moisture or water ingress.

[0030] Preferably, in this embodiment, multiple sets of reinforcing rods 25 are installed between the mounting frame 3 and the rectangular frame 1. The multiple sets of reinforcing rods 25 can significantly enhance the connection rigidity between the mounting frame 3 and the rectangular frame 1, reduce the relative displacement between the two, and ensure that the platform remains stable during construction. Especially in high-altitude operations, this enhanced rigidity helps to resist the influence of wind and other external loads. With the multiple sets of reinforcing rods 25, the weight of the platform and the construction load can be more evenly distributed on each support point, avoiding local stress concentration, thereby improving the structural stability of the entire platform.

[0031] Preferably, in this embodiment, a groove 26 is provided on one side wall of the mounting bracket 3 near the tool placement box 7. A slide rod 27 is fixedly installed in the groove 26, and a slider 28 is slidably installed on the slide rod 27. The side wall of the slider 28 is fixedly connected to the side wall of the tool placement box 7. The design of the groove 26 and the slide rod 27 allows the slider 28 to flexibly adjust the position of the tool placement box 7 within a certain range to adapt to different construction needs. For example, the position of the tool placement box 7 can be adjusted according to the actual working conditions to make it easier to operate.

[0032] Preferably, in this embodiment, both the first motor 12 and the second motor 16 are waterproof motors. Waterproof motors can work normally in humid or splashing environments, effectively preventing moisture from entering the motor and avoiding malfunctions caused by short circuits or corrosion.
