Description

Technical Field

[0001] The invention relates to the technical field of bridges, and in particular to a telescopic bridge supporting structure. Background Art

[0002] An emergency bridge is a temporary bridge facility that is quickly built to ensure smooth traffic and meet the basic living needs of the people (such as evacuation of personnel, transportation of materials, etc.) when the original bridge cannot be used normally due to natural disasters such as floods, earthquakes, and certain emergencies. It has sufficient strength and the bridge needs to be quickly installed in a short time to restore traffic function.

[0003] In order to balance the force, the emergency bridge usually has two bridge parts. When erecting the emergency bridge, the two bridges need to be kept as parallel as possible. However, under extreme weather conditions, such as strong winds, heavy rains, floods, etc., the bridge construction and structural stability will be affected, resulting in the bridge arrangement being non-parallel.

[0004] When the bridges are not parallel, the force distribution between the bridges becomes uneven. This uneven force will cause certain parts to be subjected to excessive stress, thereby increasing the risk of damage to the bridge structure and causing the beams and slabs on one side to bear more loads, thereby accelerating the wear and aging of that part and causing structural safety hazards. During the construction process, the construction team will also need to take additional measures to adjust and correct the position of the bridge, which will not only increase construction costs, but may also extend the construction period and affect the use of the bridge.

[0016] The working principle and beneficial effects of the present invention are: 1. In the present invention, the relative position between the first connecting frame and the two first sliding frames on the first connecting frame is pre-adjusted so that the swing frames at both ends of the two first sliding frames are just between the two oppositely positioned transverse adjustment frames, and the swing frames at the ends of the two first sliding frames are placed in the slots on the two transverse adjustment frames at the corresponding positions, and the first connecting frame can be pulled downward, and the first connecting frame drives the two corresponding first sliding frames to move downward, thereby driving the swing frame to move through the first sliding frame until the pin is inserted into the insertion hole, and the position of the first connecting frame can be fixed, which not only allows for quick disassembly and assembly, but also facilitates the fixing of the first connecting frame, and also prevents jamming when adjusting the position between the two bridge bodies.

[0017] 2. In the present invention, the first lever drives the rotating cylinder to rotate, thereby driving the adjusting nut to rotate. Through the setting of the connecting rod and the mounting frame, the adjusting screw and the adjusting nut rotate relative to each other, driving the mounting frame to move upward, and driving the end of the connecting rod to move upward. Through the cooperation of the connecting rod and the first sliding frame, the two first sliding frames on the first connecting frame can be driven to move in the opposite direction at the same time, so as to adjust the distance between the two bridge bodies. During the adjustment process, the swing frame and the first sliding frame rotate relative to each other to avoid jamming. Then, the above steps are repeated to adjust the two first sliding frames on the other first connecting frame, so as to adjust the parallelism between the two bridge bodies. This not only facilitates the rapid adjustment of the position and parallelism between the two bridge bodies, but also through the setting of the connecting rod, the force borne by the first sliding frame can be dispersed, thereby ensuring a stable connection.

[0018] 3. In the present invention, the connecting rod is rotated by twisting the second lever, and the connecting rod drives the driven bevel gear to rotate through the active bevel gear, thereby driving the bidirectional screw to rotate. At this time, the fixed rod slides inside the bidirectional screw, and the bidirectional screw pushes the two second sliding frames on the second connecting frame to move through the setting of two second nuts, so that the two connecting columns move in the opposite direction, shortening the distance between the two connecting columns, so that the connecting columns abut against the bottom of the inclined plate and the horizontal positioning frame, and through the setting of the inclined plate, the second connecting frame is restricted, thereby tightening the two bridge bodies, further improving the structural stability of the bridge bodies.

[0019] 4. In the present invention, by setting the cross brace adjustment component, the distance and parallelism between the two bridge bodies can be quickly adjusted, and then the two bridge bodies can be quickly installed, reducing errors occurring during the construction process. By cooperating with the stabilizing component and the transverse fixing component, the two bridge bodies are fixed, and the connection between the two bridge bodies is made stronger, ensuring stability and safety in complex environments such as floods, and improving the reliability of the overall structure.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 7 As shown, this embodiment proposes a telescopic bridge support structure, including a fixing frame 1, two fixing frames 1 are provided, and two bridge bodies 2 are symmetrically provided on the upper part between the two fixing frames 1, and also include a transverse positioning frame 3, a cross brace adjustment component, a stabilization component, a transverse positioning frame 4 and a transverse fixing component.

Two cross brace adjustment components are provided between the two bridge bodies 2, and transverse positioning frames 3 are provided at both ends of the two cross brace adjustment components for adjusting the parallelism between the two bridge bodies 2. The cross brace adjustment component includes a slot 5, a socket 6, a connecting part and an adjusting part. The four transverse positioning frames 3 are provided with slots 5, and the four transverse positioning frames 3 are provided with sockets 6 inside. Two connecting parts are provided between the two bridge bodies 2, and the two connecting parts are respectively adapted to the sockets 6 for connecting the two bridge bodies 2. Adjusting parts are installed on the two connecting parts for adjusting the positions of the connecting parts.

[0024] Specifically, when installing the bridge body 2, first install the fixing frame 1, and then place the two bridge bodies 2 on the upper parts of the two fixing frames 1. At this time, first install the two connecting parts on the corresponding transverse adjustment frames 3 respectively, and put the two ends of the connecting parts into the slots 5 respectively. The position of the connecting parts is fixed by the setting of the sockets 6. At this time, the relative positions of the two bridge bodies 2 are adjusted, and the two adjustment parts are adjusted respectively, so as to adjust the position of the connecting parts. Through the cooperation between the connecting parts and the sockets 6, the relative positions between the two bridge bodies 2 are adjusted, and then the relative positions between the two bridge bodies 2 are adjusted. Then, the stabilizing components are installed to preliminarily fix the positions between the two bridge bodies 2, and then the two bridge bodies 2 are further fixed by the setting of the transverse fixing components, so as to improve the structural stability of the bridge body 2. Then, use connecting parts, such as hinged supports or other connection forms, to fix the bridge body 2 on the fixing frame 1. Finally, bridge decks are laid on the two bridge bodies 2 to complete the installation.

[0025] The above, such as Figure 3 , Figure 4 As shown, the connecting part includes a first connecting frame 7, a first sliding frame 8, a swing frame 9 and a pin 10. Two first connecting frames 7 are arranged between the two bridge bodies 2. The two first connecting frames 7 are symmetrically arranged. A first connecting frame 7 is arranged between two oppositely positioned transverse adjustment frames 3. Two first sliding frames 8 are symmetrically and slidably installed on the two first connecting frames 7. Swing frames 9 are rotatably installed on the tops of the four first sliding frames 8. The four swing frames 9 are detachably installed with pins 10, and the pins 10 are adapted to the sockets 6.

[0026] Specifically, after placing the bridge body 2, the first connecting frame 7 is moved to the required position. At this time, the relative position between the first connecting frame 7 and the two first sliding frames 8 on the first connecting frame 7 is first adjusted, so that the swing frames 9 at both ends of the two first sliding frames 8 are just between the two opposite transverse adjustment frames 3, and the swing frames 9 at the ends of the two first sliding frames 8 are placed in the slots 5 on the two transverse adjustment frames 3 at the corresponding positions, and the first connecting frame 7 can be pulled downward, and the first connecting frame 7 drives the two corresponding first sliding frames 8 to move downward, thereby driving the swing frame 9 to move through the first sliding frame 8 until the pin 10 is inserted into the socket 6, so that the position of the first connecting frame 7 can be fixed, and the above steps are repeated to install another first connecting frame 7. After installation, the relative position between the two bridge bodies 2 can be adjusted.

[0027] The above, such as Figure 3As shown, the positioning part includes a rotating cylinder 11, a first shifting rod 12, a positioning nut 13, a positioning screw 14, a mounting frame 15 and a connecting rod 16. The rotating cylinder 11 is rotatably mounted on the bottom of the two first connecting frames 7. The first shifting rod 12 can be detachably mounted on the two rotating cylinders 11. The positioning nuts 13 are fixedly mounted on the bottom of the two rotating cylinders 11. The positioning screws 14 are threadedly arranged on the two adjusting nuts 13. The mounting frames 15 are fixedly mounted on the bottom of the two adjusting screws 14. Connecting rods 16 are rotatably mounted on both ends of the two mounting frames 15. The two connecting rods 16 are rotatably connected to the two first sliding frames 8 on the first connecting frame 7 respectively.

[0028] Specifically, when adjusting the relative position between the two bridge bodies 2, first hold one of the first levers 12, rotate the first lever 12 to drive the rotating cylinder 11 to rotate, thereby driving the adjusting nut 13 to rotate, and through the setting of the connecting rod 16 and the mounting frame 15, the adjusting screw 14 and the adjusting nut 13 rotate relative to each other, thereby driving the mounting frame 15 to move upward, which can drive the end of the connecting rod 16 to move upward, and through the cooperation of the connecting rod 16 and the first sliding frame 8, the two first sliding frames 8 on the first connecting frame 7 can be driven to move in the opposite direction at the same time, thereby adjusting the distance between the two bridge bodies 2. During the adjustment process, the swing frame 9 and the first sliding frame 8 rotate relative to each other to avoid jamming, and then repeat the above steps to adjust the two first sliding frames 8 on the other first connecting frame 7, thereby adjusting the parallelism between the two bridge bodies 2.

[0029] like Figure 5 As shown, a telescopic stabilizing assembly is installed between the two bridge bodies 2 for fixing the two bridge bodies 2. The stabilizing assembly includes a stabilizing rod 17, a connecting frame 18 and a pull rod 19. Two stabilizing rods 17 are fixedly installed at the bottom of the two bridge bodies 2. A connecting frame 18 is fixedly installed at the bottom of the four stabilizing rods 17. Pull rods 19 are rotatably installed at both ends of the four connecting frames 18. The pull rods 19 are detachably connected to the bottom of the bridge body 2 and also include an oblique rod 20 and a mounting portion. An oblique rod 20 is arranged on both sides of the four stabilizing rods 17. The two oblique rods 20 are cross-arranged. A mounting portion is installed on the two oblique rods 20 for fixing the relative positions of the oblique rod 20 and the stabilizing rod 17.

[0030] Specifically, after adjusting the distance and angle between the two bridge bodies 2, the bridge body 2 can be fixed on the fixed frame 1, and then the position between the two bridge bodies 2 needs to be further fixed. At this time, through the setting of the stabilizer bar 17, the pull rods 19 are respectively installed at both ends of the connecting frame 18 at the bottom of the stabilizer bar 17. The two corresponding pull rods 19 have the same length. Then the pull rods 19 can be installed at the bottom of the mixed bridge body 2 through a hinge support or the like, and then the diagonal rod 20 can be installed between the four stabilizer bars 17 through the mounting part.

[0031] The above, such as Figure 5 As shown, the mounting portion includes a first clamp 21 and a second clamp 22. Four first clamps 21 are detachably mounted on the two diagonal rods 20. Second clamps 22 are rotatably mounted on the four first clamps 21 on one diagonal rod 20. The four second clamps 22 correspond to four stabilizing rods 17 one by one, respectively, and the second clamps 22 are detachably connected to the stabilizing rods 17.

[0032] Specifically, when installing the diagonal rod 20, first determine the position of the first clamp 21 on the diagonal rod 20 according to the distance between the two bridge bodies 2, and then install the first clamp 21 on the diagonal rod 20. After adjusting the position of the diagonal rod 20 and the four stabilizing rods 17, rotate the first clamp 21 to fix the diagonal rod 20 on the stabilizing rod 17, repeat this step, and install another diagonal rod 20. The two diagonal rods 20 are respectively located on both sides of the four stabilizing rods 17, and the two diagonal rods 20 are arranged crosswise.

[0033] like Figure 6 , Figure 7 As shown, two transverse positioning frames 4 are symmetrically installed on the two bridge bodies 2, and the two transverse positioning frames 4 on the two bridge bodies 2 correspond to each other. The two transverse positioning frames 4 on the bridge body 2 are located between the two transverse adjustment frames 3. Two transverse fixing components are arranged between the two bridge bodies 2. Both ends of the two transverse fixing components are provided with transverse positioning frames 4 for fixing the two bridge bodies 2. The transverse fixing components include a mounting groove 23, an inclined plate 24, a second connecting frame 25, a second sliding frame 26, a fixing rod 27, a connecting column 28 and a pulling part. The four transverse positioning frames 4 are provided with mounting grooves 23. The four transverse positioning frames 4 are provided with mounting grooves 23. Two inclined plates 24 are symmetrically and fixedly installed on the two parts, two second connecting frames 25 are arranged between the two bridge bodies 2, the two second connecting frames 25 are symmetrically arranged, a second connecting frame 25 is arranged between the two opposite transverse positioning frames 4, two second connecting frames 25 are symmetrically and slidably installed on the two second connecting frames 26, fixing rods 27 are fixedly installed on the four second sliding frames 26, connecting columns 28 are fixedly installed on one end of the four fixing rods 27, the connecting columns 28 are abutted against the inclined plates 24, and pulling parts are installed on the two second connecting frames 25 for fixing the position between the two opposite transverse positioning frames 4.

[0034] Specifically, after the inclined rod 20 is installed, in order to further improve the stability of the structure between the two bridge bodies 2, it is necessary to install the second connecting frame 25, move the second connecting frame 25 to the required position, and at this time, first adjust the relative position between the second connecting frame 25 and the two second sliding frames 26 on the second connecting frame 25, so that the connecting columns 28 at the ends of the fixing rods 27 on the two second sliding frames 26 are just between the two opposite transverse positioning frames 4, and place the connecting columns 28 at the ends of the fixing rods 27 on the two second sliding frames 26 on the two transverse positioning frames 4 at the corresponding positions. The second connecting frame 25 can be pulled downward into the installation groove 23 on the upper part, and the second connecting frame 25 drives the two corresponding second sliding frames 26 to move downward, thereby driving the fixing rod 27 to move through the second sliding frame 26 until the connecting column 28 moves to the bottom of the inclined plate 24, and then the relative position between the two second sliding frames 26 on the second connecting frame 25 is adjusted through the setting of the pulling part, so that the two bridges are pulled as a whole through the cooperation of the connecting column 28 and the inclined plate 24 to improve stability, and repeat the above steps to install another second connecting frame 25.

[0035] The above, such as Figure 6 As shown, the pulling part includes a bidirectional screw 29 and a second nut 30. The bidirectional screws 29 are rotatably installed inside the two second connecting frames 25. The bidirectional screws 29 are hollow structures. The inside of the bidirectional screws 29 is respectively slidably matched with the two fixed rods 27. The two bidirectional screws 29 are symmetrically and threadedly provided with two second nuts 30, wherein the four second nuts 30 are respectively fixedly connected to the four second sliding frames 26, and also include a driven bevel gear 31, a driving bevel gear 32, a connecting rod 33 and a second shifting rod 34. The two bidirectional screws 29 are fixedly installed with the driven bevel gear 31, the two second connecting frames 25 are rotatably installed with the driving bevel gear 32, the driving bevel gear 32 is meshed with the driven bevel gear 31, the two driving bevel gears 32 are fixedly installed with a connecting rod 33, the connecting rod 33 is rotatably matched with the second connecting frame 25, and the second shifting rod 34 can be detachably installed on the two connecting rods 33.

[0036] Specifically, when adjusting the two second sliding frames 26 on the second connecting frame 25, hold the second lever 34, and turn the connecting rod 33 through the second lever 34 to rotate, so that the connecting rod 33 drives the active bevel gear 32 to rotate, and the active bevel gear 32 drives the driven bevel gear 31 to rotate, thereby driving the bidirectional screw 29 to rotate. When the bidirectional screw 29 rotates, the fixing rod 27 slides inside the bidirectional screw 29, and the bidirectional screw 29 can push the two second sliding frames 26 on the second connecting frame 25 to move through the setting of the two second nuts 30. At this time, the connecting columns 28 on the two fixing rods 27 are not in contact with the bottom of the inclined plate 24 and the horizontal positioning frame 4. With the movement of the two second sliding frames 26 on the second connecting frame 25, the two connecting columns 28 move in the opposite direction, shortening the distance between the two connecting columns 28, so that the connecting columns 28 abut against the bottom of the inclined plate 24 and the horizontal positioning frame 4, thereby playing the effect of tightening the two bridge bodies 2, thereby further improving the structural stability of the bridge body 2 and enabling it to bear a larger load.

[0037] The working principle or usage process of this application is: When installing the bridge body 2, first install the fixing frame 1, then place the two bridge bodies 2 on the upper parts of the two fixing frames 1, and then move the first connecting frame 7 to the required position. At this time, first adjust the relative position between the first connecting frame 7 and the two first sliding frames 8 on the first connecting frame 7, so that the swing frames 9 at both ends of the two first sliding frames 8 are just between the two opposite transverse adjustment frames 3, and place the swing frames 9 at the ends of the two first sliding frames 8 in the slots 5 on the two transverse adjustment frames 3 at the corresponding positions, and then pull the first connecting frame 7 downward, and the first connecting frame 7 drives the two corresponding first sliding frames 8 to move downward, thereby driving the swing frame 9 to move through the first sliding frame 8 until the pin 10 is inserted into the socket 6, so that the position of the first connecting frame 7 can be fixed, and repeat the above steps to install another first connecting frame 7 in place.

[0038] When adjusting the relative position between the two bridge bodies 2, first hold one of the first levers 12, rotate the first lever 12 to drive the rotating cylinder 11 to rotate, thereby driving the adjusting nut 13 to rotate, and through the setting of the connecting rod 16 and the mounting frame 15, the adjusting screw 14 and the adjusting nut 13 rotate relative to each other, thereby driving the mounting frame 15 to move upward, which can drive the end of the connecting rod 16 to move upward, and through the cooperation of the connecting rod 16 and the first sliding frame 8, the two first sliding frames 8 on the first connecting frame 7 can be driven to move in the opposite direction at the same time, thereby adjusting the distance between the two bridge bodies 2. During the adjustment process, the swing frame 9 and the first sliding frame 8 rotate relative to each other to avoid jamming, and then repeat the above steps to adjust the two first sliding frames 8 on the other first connecting frame 7, thereby adjusting the parallelism between the two bridge bodies 2.

[0039] After adjusting the distance and angle between the two bridge bodies 2, the bridge body 2 can be fixed on the fixed frame 1, and then the position between the two bridge bodies 2 needs to be further fixed. At this time, through the setting of the stabilizing rod 17, the pull rods 19 are respectively installed at both ends of the connecting frame 18 at the bottom of the stabilizing rod 17, and the two corresponding pull rods 19 have the same length. Then, the pull rods 19 are installed on the bottom of the bridge body 2 through hinge supports, etc., and then the position of the first clamp 21 on the diagonal rod 20 is determined according to the distance between the two bridge bodies 2, and the first clamp 21 is installed on the diagonal rod 20. After adjusting the position of the diagonal rod 20 and the four stabilizing rods 17, the first clamp 21 is rotated to fix the diagonal rod 20 on the stabilizing rod 17, and this step is repeated to install another diagonal rod 20. The two diagonal rods 20 are respectively located on both sides of the four stabilizing rods 17, and the two diagonal rods 20 are cross-arranged, so as to fix the two bridge bodies 2 and stabilize the structure of the bridge body 2.

[0040] In order to further improve the structural stability between the two bridge bodies 2 and increase the load, it is necessary to install the second connecting frame 25 and move the second connecting frame 25 to the required position. At this time, first adjust the relative position of the second connecting frame 25 and the two second sliding frames 26 on the second connecting frame 25 so that the connecting column 28 at the end of the fixing rod 27 on the two second sliding frames 26 is just between the two opposite transverse positioning frames 4, and place the connecting column 28 at the end of the fixing rod 27 on the two second sliding frames 26 in the mounting groove 23 on the two transverse positioning frames 4 at the corresponding positions, and then pull the second connecting frame 25 downward, and the second connecting frame 25 drives the two corresponding second sliding frames 26 to move downward, thereby driving the fixing rod 27 to move through the second sliding frame 26 until the connecting column 28 moves to the bottom of the inclined plate 24, and then hold the second lever 34, and turn the connecting rod 33 through the second lever 34 to rotate, and the connecting rod 3 3 drives the active bevel gear 32 to rotate, and the active bevel gear 32 drives the driven bevel gear 31 to rotate, thereby driving the bidirectional screw 29 to rotate. When the bidirectional screw 29 rotates, the fixing rod 27 slides inside the bidirectional screw 29, and the bidirectional screw 29 can push the two second sliding frames 26 on the second connecting frame 25 to move through the setting of the two second nuts 30. With the movement of the two second sliding frames 26 on the second connecting frame 25, the two connecting columns 28 move in the opposite direction, shortening the distance between the two connecting columns 28, so that the connecting columns 28 abut against the bottom of the inclined plate 24 and the horizontal positioning frame 4, thereby playing the effect of tightening the two bridge bodies 2, thereby further improving the structural stability of the bridge body 2 and enabling it to bear a larger load. Repeat the above steps to install another second connecting frame 25. After the installation is completed, the bridge deck is finally laid on the two bridge bodies 2 to complete the installation.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
