Description

Technical Field

[0001] This utility model relates to the field of steel casing reinforcement construction for bridge piers in water-related areas. More specifically, this utility model relates to an integrated working system for steel casing reinforcement construction of bridge piers in water-related areas. Background Technology

[0002] my country boasts numerous bridges and a long history of bridge construction, particularly massive bridges spanning rivers. The piers of these water-crossing bridges directly face the impact of water flow, leading to durability and load-bearing capacity issues due to erosion and scouring. This is especially pronounced in marine environments, where steel casing reinforcement is a common method. However, pier reinforcement work, especially the installation of steel casings, takes place entirely below the bridge's projection plane. Lifting equipment cannot operate uncovered on the bridge, and crane vessels cannot function properly due to clearance limitations. Furthermore, because full-section reinforcement of the piers is required, it's impossible to construct a platform on the pier itself. Using conventional suspended platforms or scaffolds would require lifting points on the superstructure, potentially damaging it, especially during drilling or welding of steel box girders.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] like Figure 1-6 As shown, a preferred embodiment of this utility model provides an integrated working system for reinforcing bridge piers with steel casings, including a load-bearing hanger 1, a hoisting, lifting, and translating system 2, and a lifting platform system 3; wherein, The load-bearing hanger 1 is erected on top of the pier 5 and connected to the bottom of the bridge steel box girder; the hoisting, lifting and translating system 2 is suspended below the load-bearing hanger and is used to realize the vertical movement of the steel casing Harvard segment 4. Lifting and horizontal translation; The lifting platform system 3 is suspended under the load-bearing hanger and is arranged around the pier 5 for operation by workers.

[0026] In the above technical solution, when reinforcing the piers of bridges in water-related areas, the load-bearing hanger 1 is first installed in place, firmly connecting it to the bottom of the bridge's steel box girder to ensure the stability of the entire system. Then, the steel casing Harvard segment 4 is lifted from the bridge deck or other transfer point using the hoisting and translating system 2. The vertical lifting function of this system is used to raise the segment to the required height, and then the horizontal translation function moves it to the vicinity of the corresponding installation position on the pier. Simultaneously, workers stand on the lifting platform system 3, and as the platform rises and falls to the working height, they coordinate with the hoisting and translating system 2 to align and splice the steel casing segments. Compared to traditional decentralized construction equipment, this integrated working system effectively reduces the coordination between different devices, improving construction efficiency. Furthermore, since all system components are integrated based on the load-bearing hanger, the overall structural stability is better, and construction safety in water-related environments is significantly improved, enabling more efficient and safer completion of the reinforcement task of encasing the steel casing around the piers of bridges in water-related areas.

[0027] In another technical solution, the load-bearing hanger 1 includes a steel frame 1.1, turnbuckles 1.4, and prefabricated clips 1.5; the steel frame 1.1 has a grid-like structure, and its top is connected to the prefabricated clips 1.5 through the turnbuckles 1.4. The prefabricated clips 1.5 are snapped into the bottom of the bridge steel box girder, thereby achieving a tight fixation between the steel frame 1.1 and the bottom of the steel box girder; the hoisting, lifting, and translation system is installed at the bottom of the steel frame.

[0028] In the above-mentioned technical solution, during the installation of the load-bearing hanger, the prefabricated clips 1.5 are first snapped into appropriate positions on the bridge steel box girder. By adjusting the length of the turnbuckles 1.4, the steel frame 1.1 is gradually brought closer to the bottom of the steel box girder until it is tightly pressed against the bottom. At this point, through the combined action of the turnbuckles 1.4 and the prefabricated clips 1.5, the steel frame 1.1 is firmly fixed to the bottom of the steel box girder. Because the steel frame 1.1 adopts a grid-like structure, it has good load-bearing capacity and can evenly transfer the loads generated by the hoisting, lifting, and translation system, as well as the loads generated during subsequent construction, to the steel box girder, avoiding excessive local stress that could damage the steel box girder structure.

[0029] In another technical solution, the load-bearing hanger further includes an upper movable connector 1.2 and a lower movable connector 1.3; the steel frame 1.1 is rotatably connected to the turnbuckle through the upper movable connector 1.2, and rotatably connected to the hoisting and translation system through the lower movable connector 1.3, so as to adapt to different pier sizes and the longitudinal and transverse slopes of the bridge.

[0030] In the above technical solutions, when dealing with piers of different sizes, the hoisting and translating system and the lifting platform system need to be adjusted in position and angle to accommodate the piers due to the differences in their cross-sectional dimensions. In this case, the lower movable connector 1.3 allows the hoisting and translating system to rotate relative to the steel frame 1.1, thereby adjusting its relative position to the pier. For bridges with longitudinal and transverse slopes, the steel box girder itself has a certain inclination angle. The upper movable connector 1.2 allows the steel frame 1.1 to rotate relative to the turnbuckle 1.4 and the prefabricated clip 1.5, thereby adjusting the levelness or inclination angle of the steel frame 1.1 to adapt to the longitudinal and transverse slopes of the bridge.

[0031] In another technical solution, the assembled buckle adopts a bolt connection structure, which can be opened and closed independently to achieve quick clamping and disassembly with the steel box girder flange.

[0032] In another technical solution, the lifting platform system includes a working platform 3.1, a limiting device 3.2, and a lifting mechanism 3.3. The working platform 3.1 is a grid-like structure composed of two long longitudinal platforms and two short transverse platforms, which surrounds the outside of the pier. There are two limiting devices 3.2, which are respectively set on the two short transverse platforms of the working platform. The limiting device includes limiting blocks on both sides, which are detachably snapped together. The shape of the end of the limiting block facing the pier is adapted to the outer surface of the pier. Multiple limiting blocks and two long longitudinal platforms together hold the pier in place.

[0033] In the above technical solution, when using the lifting platform system, the working platform 3.1 is first lifted to the required working height by the lifting mechanism 3.3. After the working platform 3.1 reaches the designated position, the limiting device 3.2 is operated to engage the limiting blocks on both sides. Since the end of the limiting block facing the pier is adapted to the outer surface of the pier, the limiting block will be in close contact with the outer surface of the pier at this time. In addition, the two long longitudinal platforms surround the pier, together fixing the working platform 3.1 in the current position and preventing it from shaking or displacing during operation.

[0034] In another technical solution, the hoisting and translation system includes a track 2.1, a hoist 2.2, a lifting device 2.3, and a clamping device 2.4. The track 2.1 is assembled at the bottom of the steel frame 1.1, and the clamping device 2.4 is located between the track and the steel box girder to limit and fix the track 2.1 and the steel box girder. The hoist 2.2 is slidably assembled on the track 2.1 and can move horizontally along the track 2.1 to achieve vertical lifting. The lifting device 2.3 is fixed at the hook of the hoist 2.2 and is used to receive the steel casing Harvard segment 4 transferred from the bridge deck.

[0035] In the above technical solution, when the steel casing Harvard segment is transferred from the bridge deck to the vicinity of the hoisting and translating system, the hoist 2.2 is operated to lower its hook, which is then connected and fixed to the steel casing Harvard segment via the lifting device 2.3. Subsequently, the hoist 2.2 is activated to vertically lift the steel casing Harvard segment to the required height. Next, the hoist 2.2 is driven to move horizontally along the track 2.1, translating the steel casing Harvard segment to the corresponding installation position above the pier. This achieves precise transportation of the steel casing Harvard segment from the transfer point to the installation position.

[0036] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
