Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a temporary support construction device for suspension bridge construction. Background Technology

[0002] As one of the main forms of long-span bridges, suspension bridges involve core construction processes such as main cable erection, stiffening girder installation, and tower construction. These processes require temporary support structures to provide a stable load-bearing platform.

[0003] Existing temporary support structures for steel trusses are susceptible to wind loads and are prone to geometric nonlinear deformation under wind-vibration coupling conditions, which significantly increases the risk of structural instability. They are prone to deformation or even instability, have insufficient wind resistance, and cannot meet the requirements for high-altitude operations on long-span suspension bridges. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a temporary support erection device for suspension bridge construction, thereby solving the technical problem that traditional support erection devices in the prior art have insufficient wind resistance.

[0007] Damping components are installed inside each of the support frames;

[0008] The damping assembly includes a first slide bar, two sets of the first slide bars are installed in the support frame, a first slide plate is installed on the two sets of the first slide bars, two sets of first springs are installed on both sides of the first slide plate, two sets of second slide bars are provided at the bottom of the first slide plate, a second slide plate is installed on the two sets of second slide bars, two sets of second springs are installed on both sides of the second slide plate, and multiple sets of mass blocks are installed at the bottom of the second slide plate.

The wind-resistant cable assembly includes four sets of fixed supports, two sets of fixed supports are respectively installed on both sides of the first load-bearing frame, and the bottom of the other two sets of fixed supports are connected to the cement base. Each fixed support is equipped with a tension cylinder.

[0010] The above technical solution further includes: each of the four sets of tension cylinders is provided with a buffer pad, each of the buffer pads is provided with a tension rod on one side, each of the tension rods is provided with a compression spring, one end of each of the four sets of compression springs is connected to the four sets of tension cylinders respectively, and one end of each of the four sets of tension rods is provided with a buckle.

[0011] The four sets of latches are connected by two sets of windproof cables.

[0012] The above technical solution further includes: four sets of load-bearing columns are installed on the first load-bearing frame, the tops of the four sets of load-bearing columns are all connected to the second load-bearing frame, an annular plate is installed on the second load-bearing frame, and guardrails are provided around the annular plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up damping components and wind-resistant cable components, when the main structure vibrates due to wind load, the mass block tends to maintain its original state due to inertia, opposite to the direction of vibration of the structure; the acceleration of the mass block generates a reverse inertial force to counteract the vibration of the device. With the setting of four sets of first springs and four sets of second springs, the mass block always has a centripetal force to return to center, and will automatically return to center after the device stops vibrating; at the same time, the compression spring in the wind-resistant cable component can reduce the vibration of the device, and the wind-resistant cable limits the vibration range of the device, thus solving the problem of insufficient wind resistance.

[0018] 2. By setting up moving rails and sliding rails, the moving rails can move laterally on the lifting platform, and the sliding rails can move longitudinally on the moving rails. The lifting mechanism can achieve multi-directional displacement, which is convenient for quick adjustment to the target positioning point and supports the construction structure at different locations, making the device more practical.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a temporary support erection device for suspension bridge construction, including multiple sets of support frames 1 installed on a cement base, and each support frame 1 is equipped with a damping component.

[0029] The damping assembly includes a first slide bar 2. Two sets of first slide bars 2 are installed inside the support frame 1. A first slide plate 3 is installed on the two sets of first slide bars 2. Two sets of first springs 4 are installed on both sides of the first slide plate 3. Two sets of second slide bars 5 are set at the bottom of the first slide plate 3. A second slide plate 6 is installed on the two sets of second slide bars 5. Two sets of second springs 7 are installed on both sides of the second slide plate 6. Multiple sets of mass blocks 10 are installed at the bottom of the second slide plate 6. When the device vibrates due to wind load, the mass blocks 10 tend to maintain their original state due to inertia, opposite to the vibration direction of the structure. The acceleration of the mass blocks 10 generates a reverse inertial force, which cancels the vibration of the structure. Through the setting of four sets of first springs 4 and four sets of second springs 7, the mass blocks 10 always have a centripetal force to return to the center. After the device stops vibrating, it will automatically return to the center.

[0030] One of the support frames 1 is equipped with a first load-bearing frame 11 at the top. The first load-bearing frame 11 is equipped with wind-resistant cable assemblies around its perimeter. The wind-resistant cable assemblies include four sets of fixed supports 13. Two sets of fixed supports 13 are installed on both sides of the first load-bearing frame 11, and the bottom of the other two sets of fixed supports 13 are connected to the cement base. Tension cylinders 14 are installed on each of the fixed supports 13.

[0031] Each of the four sets of tension cylinders 14 is equipped with a buffer pad 15. A tension rod 16 is provided at one end of the buffer pad 15. Compression springs 17 are installed around the periphery of the tension rod 16. One end of each of the four sets of compression springs 17 is connected to the four sets of tension cylinders 14. A lock 18 is installed at one end of each of the four sets of tension rods 16.

[0032] The four sets of latches 18 are connected by two sets of windproof cables 19. When the device vibrates, the device is connected to the cement base by the windproof cables 19 to limit the vibration range of the device. At the same time, the compression spring 17 on one side is compressed due to the movement of the tension rod 16, which weakens the vibration of the device. The buffer pad 15 is made of rubber to reduce the energy of the compression spring 17 when it rebounds.

[0033] Four sets of load-bearing columns 20 are installed on the first load-bearing frame 11. The tops of the four sets of load-bearing columns 20 are all connected to the second load-bearing frame 21. An annular plate 22 is installed on the second load-bearing frame 21, and guardrails 23 are provided around the annular plate 22.

[0034] A detection bracket 24 is installed on the annular plate 22. A wind speed sensor 25 and an audible and visual alarm 26 are installed on the top of the detection bracket 24. The wind speed sensor 25 can be a Cyt-601 model, and the audible and visual alarm 26 can be an LTG-101 model. A control panel 27 is set on one side of the detection bracket 24. The control panel 27 can be an ESP32 model. The audible and visual alarm 26 and the wind speed sensor 25 are electrically connected to the control panel 27. When the construction personnel stand on the annular plate 22, when the wind speed sensor 25 detects that the wind speed is too high, the audible and visual alarm 26 will issue a warning to notify the construction personnel to evacuate quickly.

[0035] The second load-bearing frame 21 is equipped with a load-bearing plate 28, and four sets of lifting seats 29 are installed on the load-bearing plate 28. Each of the four sets of lifting seats 29 is equipped with a moving rail 30.

[0036] Each of the four sets of moving rails 30 is equipped with a slide rail, and the top of the four sets of slide rails is connected to a lifting mechanism 31. During construction, the lifting mechanism 31 can move laterally on the lifting seat 29 via the moving rails 30, and the slide rails can move longitudinally on the moving rails 30 to adjust the required fixed position and support the construction structure at different positions.

[0037] The specific usage and function of this embodiment: When using the device, construction workers stand on the annular plate 22 to carry out construction. The lifting mechanism 31 can move laterally on the lifting seat 29 via the moving rail 30, and the slide rail can move longitudinally on the moving rail 30 to adjust the required fixed position and support the construction structure at different positions. When the wind speed sensor 25 detects that the wind speed is too high, the audible and visual alarm 26 will issue a prompt to notify the construction workers to evacuate quickly.

[0038] When the device vibrates due to wind load, the mass block 10 tends to maintain its original state due to inertia, which is opposite to the vibration direction of the structure. The acceleration of the mass block 10 generates a reverse inertial force to counteract the vibration of the structure. Through four sets of first springs 4 and four sets of second springs 7, the mass block 10 always has a centripetal force to return to the center, and will automatically return to the center after the device stops vibrating.

[0039] The device is connected to the cement base by the windproof cable 19, which limits the vibration range of the device. At the same time, the compression spring 17 on one side is compressed due to the movement of the tension rod 16, which weakens the vibration of the device. The buffer pad 15 is made of rubber, which reduces the energy of the compression spring 17 when it rebounds.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
