Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and more specifically, it relates to a steel box girder docking and leveling control device. Background Technology

[0002] Steel box girders for steel structure bridges are typically fabricated in sections and then joined together on the bridge. The ends of the two joined sections each extend with a certain length of I-beam. During the joining process, a crane lifts one section to be installed and levels and aligns it with the end of another already installed section. Then, using clamps and bolts, the I-beams at the ends of the two sections are fixed. When aligning the I-beams of the steel box girder, workers typically use clamps to extend inside the upper flange of the fixed I-beam and then align the I-beams to be joined.

[0003] The existing application number is CN202121644857.9. This utility model relates to a rapid docking and leveling device for steel box girders, including a reaction beam. A first support rod and a second support rod, perpendicular to the reaction beam, are welded to one end and the middle of the reaction beam, respectively. A connecting plate is welded to the lower end of the second support rod. The connecting plate is connected to a clamp by bolts. The clamp includes a clamping plate, the length of which is greater than the width of the flange of the I-beam at the end of the steel box girder. An L-shaped hook is fixedly installed at the bottom of each end of the clamping plate, with the two hooks facing each other and the distance between the opposite ends of the hooks being less than the width of the flange of the I-beam at the end of the steel box girder. By supporting the support rods of this utility model on the beam segment to be installed, and using jacks to push the reaction beam upwards on the already installed beam segment, the ends of the two beam segments can be quickly leveled, improving construction efficiency.

[0004] Based on the above, existing connecting clamps are generally fixed to the connecting device with bolts, which makes it inconvenient to adjust the width of the clamps and limits their applicability. Moreover, after the steel box girder is connected, all the bolts on the clamps need to be unscrewed before the clamps can be disassembled, which makes it inconvenient to disassemble the docking device and affects the construction efficiency of the steel box girder.

[0024] Furthermore, the connection and disassembly mechanism also includes a connection clamping member;

[0025] The connecting clamps are provided in two sets. Both sets of connecting clamps are L-shaped plate structures. The two sets of connecting clamps are slidably connected to the left and right sides of the connecting slide, and the inner upper end face of both sets of connecting clamps is in contact with the upper flange end face of the fixed I-beam.

[0026] Furthermore, the connection and disassembly mechanism also includes a clamping drive rod;

[0027] The clamping drive rods are provided in two sets. The upper ends of the two sets of clamping drive rods are respectively hinged to the left and right sides behind the clamping drive slider, and the lower ends of the two sets of clamping drive rods are respectively hinged to the connecting clamping parts.

[0028] Furthermore, the connection and disassembly mechanism also includes: a docking limiting plate and a docking guide plate;

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] This utility model, through the setting of the support display mechanism, when the I-beam to be installed and the fixed I-beam are connected, the I-beam to be installed is moved upward by the crane. When the I-beam to be installed moves upward and contacts the support connecting pad, the display switch under the support connecting pad is squeezed, and the display switch is squeezed to turn on the contact indicator light. The contact indicator light shines, reminding the worker that the I-beam to be installed and the fixed I-beam are in a horizontal state.

[0033] This invention, through the setting of a support display mechanism, allows for the docking of steel box girders. A set of rear support connecting pads is placed on a fixed I-beam. Turning the operating handwheel rotates the clamping drive screw, which in turn moves the clamping drive slider upwards. This upward movement causes two sets of connecting clamps to move in opposite directions, inserting them into the inner side of the upper flange of the fixed I-beam. At this point, the entire docking device connects with the fixed I-beam. The I-beam to be installed is then hoisted upwards. Once the I-beam contacts the front set of support connecting pads, the horizontal adjustment of the steel box girder I-beam is achieved, facilitating docking. Simultaneously, the opposing movement of the connecting clamps allows for the connection of different types of steel box girders, increasing the applicability of the entire docking device. When disassembly of the entire docking device is required, reversing the operating handwheel causes the two sets of connecting clamps to move in opposite directions, enabling disassembly of the entire docking device. This facilitates disassembly and improves the construction efficiency of the steel box girder. Attached Figure Description

At this time, the I-beam 2 to be installed and the fixed I-beam 1 are at the same horizontal position.

[0056] Example 2:

[0057] This utility model provides a steel box girder docking and leveling control device, which is based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a connection and disassembly mechanism, which is located below the docking connection frame 3.

[0058] The connection and disassembly mechanism includes: a clamping drive screw 501, an operating handwheel 502, a clamping drive slider 503, a connecting clamping component 504, a clamping drive rod 505, a docking limit plate 506, and a docking guide plate 507.
