It can complete the erection of beams of flood-damaged bridges without the use of large lifting equipment, and the construction is fast and low-cost.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 like Figures 1-7As shown, this embodiment provides a rapid erection device for bridge beams damaged by water, including a beam erection truss 1, a pilot truss 2, a deflection adjustment device 3, a truss jacking device 4, a truss lifting device 5, a rolling support device 6, a reaction device 7, and an anchoring device 8. The pilot truss 2 is installed at the front end of the beam erection truss 1, and the deflection adjustment device 3 is installed at the bottom front side of the pilot truss 2. It is used to adjust the deflection of the pilot truss 2 and the beam erection truss 1 as a whole after reaching the previous span of the bridge deck, using the previous span as support. The beam-slab erection truss 1 is equipped with a truss lifting device 5 at each of its front and rear ends. A rolling support device 6 is located below the beam-slab erection truss 1 and makes rolling contact with the beam-slab erection truss 1 to provide rolling support for the beam-slab erection truss 1. A reaction device 7 is anchored to the roadbed 9 and / or bridge deck 10 through an anchoring device 8. A truss jacking device 4 is connected to the reaction device 7 and, supported by the reaction device 7, is used to jack the beam-slab erection truss 1 forward on the rolling support device 6. The truss lifting device 5 includes a lifting frame, which includes a lifting beam 51 and lifting telescopic supports 52 fixed to both ends of the lifting beam 51. A lateral moving device 53 is installed on the lifting beam 51. The beam-plate erecting truss 1 is connected to the lateral moving device 53. The lateral moving device 53 can drive the beam-plate erecting truss 1 to move laterally along the lifting beam 51. The lateral moving device 53 can be a mechanism with powered rollers. The powered rollers are driven by a drive motor, thereby driving the lateral moving device 53 to move laterally along the lifting beam 51. After the device 53 is connected to the beam-slab erection truss 1, it can drive the beam-slab erection truss 1 to move laterally under the action of the drive motor; the lower end of the lifting telescopic column 52 is equipped with a support walking device 54. The support walking device 54 can extend downwards into the lifting telescopic column 52 or retract into the lifting telescopic column 52. The support walking device 54 can drive the lifting frame to move laterally. The support walking device 54 can be a support roller. The support roller can extend downwards to roll and support on the bridge deck 10. Then, pushing the lifting frame can realize the lateral movement of the lifting frame. A longitudinal sliding device 12 is installed on the lower chord 110 of the beam-slab erection truss 1. The lower end of the longitudinal sliding device 12 is connected to a hoisting device 13. The hoisting device 13 is used to hoist the precast beam slab 14. The hoisted precast beam slab 14 can be moved longitudinally along the lower chord 110 of the truss through the longitudinal sliding device 12. The longitudinal sliding device 12 can be a mechanism with a roller assembly. This mechanism is rolled on the lower chord 110 of the truss through the roller assembly and can move longitudinally along the lower chord 110 of the truss. The precast beam slab 14 can be moved longitudinally along the lower chord 110 of the truss by pushing it.

[0021] This device supports the beam-slab erection truss 1 via a rolling support device 6. The two components roll in contact, resulting in low friction and facilitating the forward movement of the beam-slab erection truss 1. The truss jacking device 4, supported by the reaction device 7 and anchoring device 8, pushes the beam-slab erection truss 1 forward on the rolling support device 6. Furthermore, the pilot truss 2 and deflection adjustment device 3 ensure the beam-slab erection truss 1 smoothly passes through the hole and reaches its designated position. After the beam-slab erection truss 1 passes through the hole, the truss lifting device 5 provides temporary support for it, allowing for the removal of the pilot truss 2 and deflection adjustment device 3. After removing the pilot truss 2 and deflection adjustment device... After placement 3, the jacking telescopic support column 52 can be used to lift the beam truss 1 to the predetermined height for beam hoisting. The jacking frame is then moved laterally to the designated installation position via the support traveling device 54. The longitudinal sliding device 12 transports the hoisted precast beam 14 to the designated position. During the lowering process of the precast beam 14 via the hoisting device 13, the lateral position of the precast beam 14 is further adjusted by the lateral moving device 53 to accurately lower it onto the cap beam 11, thus completing the erection of the precast beam 14. Then, the support traveling device 54 moves it laterally to the next installation position, and the installation of each precast beam 14 is completed sequentially. Using this device, the erection of beams for flood-damaged bridges can be completed without the use of large lifting equipment. Construction is fast and cost-effective, making it particularly suitable for remote mountainous areas with poor transportation and limited surrounding geological conditions.

[0022] In this embodiment, the deflection adjustment device 3 includes a support beam 31 and a telescopic lifting device 32. The telescopic lifting device 32 can be a hydraulic cylinder.

Both ends of the telescopic lifting device 32 are rotatably connected to the pilot truss 2 and the free end of the support beam 31, respectively. After reaching the previous span 10, the deflection adjustment device 3 is supported on the previous span 10 by the support rollers 33 at the bottom of the support beam 31. The angle between the support beam 31 and the pilot truss 2 is adjusted by the extension and retraction of the telescopic lifting device 32 to achieve the deflection adjustment, so that the pilot truss 2 and the beam-plate erection truss 1 can remain horizontal and smoothly pass through the hole to reach the predetermined position.

[0023] In this embodiment, the truss jacking device 4 includes a lifting cylinder 41, a pushing cylinder 42, and a slide rail assembly.

The piston rod of the pushing cylinder 42 is rotatably connected to one side of the piston rod of the lifting cylinder 41. The cylinder of the lifting cylinder 41 is fixed to the slider 44. The piston rod of the lifting cylinder 41 can extend and retract to tighten or loosen the beam plate to erect the truss 1. During the jacking process, the piston rod of the lifting cylinder 41 extends and presses against the beam-plate erecting truss 1. Then, the piston rod of the pushing cylinder 42 extends, pushing the lifting cylinder 41 to move along the slide rail 43. Rubber pads to increase friction can be placed on the contact surface between the piston rod of the lifting cylinder 41 and the beam-plate erecting truss 1, so that the beam-plate erecting truss 1 can be moved forward through friction. After one jacking operation, the piston rod of the lifting cylinder 41 retracts to its original position, and the piston rod of the pushing cylinder 42 retracts to its original position. This process is repeated to achieve continuous jacking of the beam-plate erecting truss 1.

[0024] In this embodiment, the supporting walking device 54 is vertically slidably connected to the lower end of the lifting telescopic column 52. A driving cylinder is connected between the supporting walking device 54 and the lifting telescopic column 52. The driving cylinder drives the supporting walking device 54 to extend downwards into the lifting telescopic column 52 or retract into the lifting telescopic column 52. When lateral movement is required, the supporting walking device 54 is extended downwards to move laterally via its rollers. After moving into position, the supporting walking device 54 is retracted, and the lifting telescopic column 52 continues to provide support, improving the stability of the support.

[0025] In this embodiment, the longitudinal sliding device 12 is connected to the lower chord 110 of the truss by rollers to reduce the moving friction and facilitate the longitudinal movement of the precast beam slab 14.

[0026] In this embodiment, the rolling support device 6 includes a base 61 and a plurality of rollers 62 rotatably connected to the base 61. The base 61 is anchored to the roadbed 9 and / or bridge deck 10 by an anchoring device 8.

[0027] In this embodiment, the lifting telescopic support column 52 includes a fixed column 521, a movable column 522, and a telescopic cylinder 523. The upper end of the fixed column 521 is fixed to the lifting beam 51, and the movable column 522 is slidably connected to the lower end of the fixed column 521. The telescopic cylinder 523 connects the fixed column 521 and the movable column 522, and drives the movable column 522 to move up and down. The structure is simple and the control is convenient.

After the support beam 31 of the deflection adjustment device 3 reaches and contacts the previous span bridge deck 10, start the deflection adjustment device 3. The deflection adjustment device 3 uses the previous span bridge deck 10 as support and adjusts the overall deflection of the pilot truss 2 and the beam-plate erection truss 1 by telescopic jacking device 32 so that the overall pilot truss 2 and the beam-plate erection truss 1 remain horizontal. Continue to push the beam-plate erection truss 1 forward until the beam-plate erection truss 1 passes through the hole smoothly and reaches the predetermined position. (4) Start the truss lifting device 5 at both ends, so that the lifting telescopic column 52 extends and supports the bridge deck 10 of the previous span, and temporarily supports the beam erection truss 1. Then remove the pilot truss 2 and the deflection adjustment device 3; continue to lift so that the beam erection truss 1 reaches the predetermined height for beam hoisting. (5) Extend the support walking device 54 downwards, move the lifting frame laterally to the designated installation position through the support walking device 54, and then retract the support walking device 54 into the lifting telescopic column 52, which supports the bridge deck 10. (6) The precast beam 14 is hoisted onto the longitudinal sliding device 12 by the hoisting device 13, and the hoisted precast beam 14 is transported to the designated position by the longitudinal sliding device 12. Then the precast beam 14 is lowered, and the lateral position of the precast beam 14 is further adjusted by the lateral moving device 53, so that the precast beam 14 is accurately lowered onto the cap beam 11.

The deflection adjustment device uses the previous span of the bridge as support to adjust the overall deflection of the pilot truss and the beam-plate erection truss. The beam-plate erection truss is pushed forward until the beam-plate erection truss reaches the predetermined position through the hole. (4) Start the truss lifting device at both ends to extend the lifting telescopic column and support it on the previous span of the bridge. Then remove the pilot truss and the deflection adjustment device. Continue lifting to make the beam erection truss reach the predetermined height for beam hoisting. (5) Extend the supporting walking device downwards, move the lifting frame laterally to the designated installation position through the supporting walking device, and then retract the supporting walking device into the lifting telescopic column, which supports it on the bridge surface. (6) The precast beam is hoisted onto the longitudinal sliding device by the hoisting device, and the hoisted precast beam is transported to the designated position by the longitudinal sliding device. Then the precast beam is lowered and the lateral position of the precast beam is further adjusted by the lateral moving device to accurately lower the precast beam onto the cap beam. (7) Repeat steps (5) and (6) to complete the installation of all precast beams and slabs.
