Description

Technical Field

[0001] This utility model relates to the technical field of opening bridge structures, specifically to a temporary support structure for opening bridges. Background Technology

[0002] A drop bridge is a special type of bridge. When a ship needs to pass through a drop bridge, a part of the bridge can be opened by lifting, rotating, or sliding to allow the ship to pass. After the ship has passed, the bridge returns to its original state for vehicles and pedestrians to pass. During the construction or maintenance of this type of drop bridge, a temporary support system is needed to temporarily support the bridge structure and ensure construction safety. However, there are still some problems with the current temporary support structure for drop bridges.

[0003] Temporary support structures for openable bridges are often constructed from steel structures, offering only basic support functions with poor buffering and protection. They are unable to cope with vibrations generated during construction and are prone to displacement. Furthermore, these support structures are often fixed, preventing flexible adjustment of the support height at each support point under the bridge. This makes it difficult to ensure minimal load deviation at each support point and affects the overall stability of the support. Based on these considerations, we propose a novel temporary support structure for openable bridges that is more practical. Utility Model Content

[0004] The purpose of this invention is to provide a temporary support structure for an opening bridge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary support structure for an openable bridge, including a main support frame. A front support column and a rear support column are respectively installed at both ends of the main support frame. A viscous damper cylinder is installed at the top of each of the front and rear support columns. A piston rod is slidably connected inside the viscous damper cylinder. A second arc-shaped rubber block is provided at the top of the piston rod. A piston body is fixed at the bottom of the piston rod. Energy dissipation holes are evenly distributed on the piston body. A hydraulic jack is fixed at the middle position inside the main support frame. A telescopic shaft is provided at the output end of the hydraulic jack. A first arc-shaped rubber block is clamped at the top of the telescopic shaft.

[0006] Preferably, there are two front support columns and two rear support columns, which are symmetrically distributed on both sides of the main support frame.

[0007] Preferably, the inner wall of the energy dissipation hole is uniformly provided with serrated grooves.

[0008] Preferably, the bottom of the viscous damper cylinder is fixed with a second threaded mounting block that is threadedly connected to the rear support column.

[0009] Preferably, the bottom of both the front support column and the rear support column is fixed with a first threaded mounting block that is threadedly connected to the main support frame.

[0010] Preferably, bridge-use pre-reserved brackets are evenly provided on both sides of the bottom of the main support frame.

[0011] Preferably, steel wire ropes are evenly installed at the bottom edge of the main support frame to improve its windproof and sturdy performance.

[0012] Preferably, the top of the wire rope cable is provided with a fixed hook, and the main support frame is provided with a fixed hanging ring that matches the fixed hook, so as to facilitate the independent disassembly and replacement of the wire rope cable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The temporary support structure of the opening bridge optimizes the structure of the device by installing the rear support column, etc. On the one hand, the front support column and the rear support column are installed at both ends of the main support frame respectively. The column structure distributed around the perimeter achieves comprehensive and uniform support for the opening bridge. The damping energy dissipation structure formed by the viscous damper cylinder, piston rod and the top of the column structure, the internal damping medium generates heat due to frictional resistance when passing through the energy dissipation hole and sawtooth groove on the piston body, converting the vibration energy received by the device into internal energy. It can absorb vibration energy well and has high stability, so that the device can reduce its own structural displacement response during construction. On the other hand, the bottom of the viscous damper cylinder is fixed with a second threaded mounting block that is threaded to the rear support column. The bottom of the front support column and the rear support column are both fixed with a first threaded mounting block that is threaded to the main support frame. With this threaded mounting structure, the viscous damper cylinder, the front support column and the rear support column can be independently disassembled and replaced, so that the device achieves the advantages of split type, which is convenient for inspection and maintenance.

[0015] (2) The temporary support structure of the opening bridge is equipped with steel wire rope cables, which allows the user to install steel wire rope cables of appropriate specifications at the bottom of the main support frame using the installation structure composed of fixed hooks and fixed hanging rings, and anchor the tail end of the steel wire rope cables to the ground anchor on the shore. This allows the device to form a tension and stability system, improving its wind resistance and firmness. On the other hand, the hydraulic jack inside the main support frame is activated and the telescopic shaft at its output end extends. The support height of each main support frame for the opening bridge can be adjusted by the first arc-shaped rubber pressure block. This facilitates the automatic adjustment of the support height of multiple main support frames distributed on the opening bridge, ensuring that the load deviation of each support point is small, optimizing the overall support effect, and enabling the linkage and cooperation of multiple main support frames.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 The present invention provides an embodiment of a temporary support structure for an openable bridge, comprising a main support frame 4, with a front support column 1 and a rear support column 3 respectively installed at both ends of the main support frame 4;

[0024] The top of the front support column 1 and the rear support column 3 are both equipped with viscous damper cylinders 11. The piston rod 13 is slidably connected inside the viscous damper cylinder 11. The top of the piston rod 13 is provided with a second arc-shaped rubber pressure block 12. The bottom of the piston rod 13 is fixed with a piston body 14. Energy dissipation holes 18 are evenly provided on the piston body 14.

[0025] The inner wall of the energy dissipation hole 18 is uniformly provided with serrated grooves 17;

[0026] The bottom of the viscous damper cylinder 11 is fixed with a second threaded mounting block 16 that is threadedly connected to the rear support column 3;

[0027] The bottom of both the front support column 1 and the rear support column 3 is fixed with a first threaded mounting block 15 that is threadedly connected to the main support frame 4;

[0028] In use, by installing front support columns 1 and rear support columns 3 of appropriate length at both ends of the main support frame 4, the column structure distributed around the perimeter achieves comprehensive and uniform support for the corresponding opening bridge. Furthermore, by utilizing the viscous damper cylinder 11, piston rod 13, and the damping energy dissipation structure formed by the viscous damper cylinder 11 and piston rod 13 at the top of the column structure, the internal damping medium generates heat due to frictional resistance when passing through the energy dissipation hole 18 and sawtooth groove 17 on the piston body 14, converting the vibration energy received by the device into internal energy. This can effectively absorb vibration energy and has high stability, thus reducing the structural displacement response of the device during construction.

[0029] A hydraulic jack 2 is fixed in the middle of the main support frame 4. A telescopic shaft 9 is provided at the output end of the hydraulic jack 2. A first arc-shaped rubber pressure block 10 is clamped on the top of the telescopic shaft 9.

[0030] When in use, the hydraulic jack 2 is started and the telescopic shaft 9 at its output end extends. The support height of each main support frame 4 for the opening bridge can be adjusted by the first arc-shaped rubber pressure block 10. This facilitates the automatic adjustment of the support height of multiple main support frames 4 distributed on the opening bridge, ensuring that the load deviation of each support point is small, optimizing the overall support effect, and enabling the linkage and cooperation of multiple main support frames 4.

[0031] There are two front support columns 1 and two rear support columns 3, which are symmetrically distributed on both sides of the main support frame 4.

[0032] Bridge-use pre-reserved clamping posts 5 are evenly provided on both sides of the bottom of the main support frame 4;

[0033] Steel wire ropes 6 are evenly installed at the bottom edge of the main support frame 4, which improves the wind resistance and sturdiness of the main support frame 4.

[0034] The top of the wire rope cable 6 is equipped with a fixed hook 7, and the main support frame 4 is equipped with a fixed hanging ring 8 that matches the fixed hook 7, so that the wire rope cable 6 can be easily disassembled and replaced independently.

[0035] In use, the user can use the installation structure consisting of the fixed hook 7 and the fixed hanging ring 8 to install the steel wire rope 6 of appropriate specifications at the bottom of the main load-bearing frame 4, and anchor the tail end of the steel wire rope 6 to the ground anchor on the shore. This allows the device to form a tensioned and stable system, improving its wind resistance and firmness.

[0036] In this embodiment, the following is achieved: Front support columns 1 and rear support columns 3 are installed at both ends of the main support frame 4. This perimeter-distributed column structure provides comprehensive and uniform support for the opening bridge. Furthermore, the viscous damper cylinder 11, piston rod 13, and other components at the top of the column structure form a damping energy dissipation structure. The internal damping medium, when passing through the energy dissipation holes 18 and serrated grooves 17 on the piston body 14, generates heat due to frictional resistance, converting the vibration energy received by the device into internal energy. This effectively absorbs vibration energy and provides high stability, reducing the structural displacement response of the device during construction. Additionally, a second threaded mounting block 16, threadedly connected to the rear support column 3, is fixed to the bottom of the viscous damper cylinder 11. First threaded mounting blocks 15, threadedly connected to the main support frame 4, are fixed to the bottom of both the front and rear support columns 1 and 3. This threaded mounting structure... The device allows for independent disassembly and replacement of the viscous damper cylinder 11, the front support column 1, and the rear support column 3, achieving the advantages of a split design and facilitating maintenance. Simultaneously, users can utilize the installation structure comprised of the fixed hooks 7 and fixed rings 8 to install appropriately sized steel wire rope cables 6 at the bottom of the main support frame 4, anchoring the tail end of the steel wire rope cables 6 to the shore anchor. This allows the device to form a tensioned and stable system, enhancing its wind resistance and robustness. Furthermore, the activation of the hydraulic jacks 2 inside the main support frame 4 and the extension of the telescopic shaft 9 at its output end allow for adjustment of the support height of each main support frame 4 relative to the opening bridge via the first arc-shaped rubber pressure block 10. This facilitates automatic adjustment of the support height of multiple main support frames 4 distributed on the opening bridge, ensuring minimal load deviation at each support point, optimizing the overall support effect, and enabling coordinated use of multiple main support frames 4.
