Description

Technical Field

[0001] This utility model relates to the field of correction reaction frames, and in particular to a correction reaction frame device for bridge jacking construction. Background Technology

[0002] Bridge launching is a common bridge construction method suitable for bridges spanning large bodies of water or complex terrain. Its main principle is to manufacture the bridge structure in sections and assemble them on the ground, then use hydraulic jacks and other equipment to push the entire bridge structure to the target position, which is the pier on the water surface or river channel. This method has the advantages of short construction period, small environmental impact and no need for a large number of temporary supports, and is widely used in projects such as long-span bridges and urban expressways.

[0003] Correction reaction frames are a common piece of equipment used in bridge construction to adjust the positional deviations of bridge components during construction. They mainly correct displacements caused by temperature changes, load effects, or construction errors by providing a counterforce. The device typically consists of a hydraulic system, a support frame, and an adjustment mechanism, which can precisely control the magnitude and direction of the force to ensure that bridge components maintain the correct geometry during construction. Correction reaction frames are widely used in the construction of large bridges, tunnels, and other complex projects, improving construction accuracy and safety.

[0004] The correction reaction frame consists of multiple hydraulic cylinders. Through the cooperation of these cylinders, the bridge can be moved in three directions to achieve the correction function. The hydraulic cylinders used to lift the bridge need to be in direct contact with the bottom of the bridge. To avoid damaging the hydraulic cylinders and abrading the bridge, rubber pads are placed between the contact surfaces for protection. However, due to constant friction during operation, the rubber pads will be damaged after prolonged use and need to be replaced in time. Traditional correction reaction frames use annular grooves on the upper part of the hydraulic cylinders to hold the rubber pads inside, which is very laborious and inconvenient to remove during replacement. Therefore, a correction reaction frame device for bridge jacking construction is proposed to solve the above problems. Utility Model Content

[0034] Working principle: When using this device, first place multiple units at the bottom of the bridge. Then, hydraulic oil is supplied to hydraulic cylinder 6 through oil pipe 18, causing hydraulic cylinder 6 to push upwards, allowing rubber pad 7 to contact the bottom of the bridge and lifting it. Next, control hydraulic cylinder 3 to work, pushing sliding frame 4 under the limit of slide plate 1, causing hydraulic cylinder 6 to move synchronously, thus starting the bridge to move. When the bridge's movement direction deviates, control hydraulic cylinder 5 to work, pushing hydraulic cylinder 6 to move and correct the direction. At the same time as sliding frame 4 moves, it drives sleeve 12 to move, pushing baffle 14 through spring 13, causing brush 15 to press against slide plate 1, thus cleaning dust and other impurities that fall on slide plate 1. Remove the rubber pad 7 to avoid wear and tear, which would affect the stability of the sliding frame 4. After a period of use, the rubber pad 7 will wear off and needs to be replaced in time. At this time, pull the rubber pad 7 upward to separate the collar 17 from the ball 11 and remove it. Then take out the new rubber pad 7, align it with the top of the hydraulic cylinder 6 and press it. At first, the collar 17 will squeeze the ball 11 and push the ball 11 into the inner shell 8, causing the limit frame 10 to compress the spring 9. When the rubber pad 7 contacts the hydraulic cylinder 6, the spring 9 will immediately push the limit frame 10, causing the limit frame 10 to reset, popping the ball 11 out and locking it inside the collar 17, thus fixing the rubber pad 7 and achieving quick replacement.
