Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a bridge jacking construction slider. Background Technology

[0002] The incremental launching construction method can use smaller power equipment to erect heavier beams, saving a lot of scaffolding and hoisting equipment. In particular, this construction method can ensure the normal passage of the crossed route and cross deep ditches and rivers that are difficult to cross. At present, the incremental launching construction method has been widely used in the construction of bridge types such as continuous beams, arch bridges, cable-stayed bridges, and self-anchored suspension bridges. When the slider is used, it needs to be quickly disassembled, replaced and installed.

[0003] However, most sliders currently available can only be used for slides of a single size and are not suitable for bridges of different sizes. Furthermore, most sliders are placed close to the outside of the slide, making it difficult to make quick adjustments when the slider is idle. Summary of the Invention

[0004] In view of this, the present invention provides a bridge jacking construction slider, which has a spring support, a load-bearing seat, and a fixed support, thereby solving the problems that most sliders can only be used for a single size of slide, are not suitable for bridges of different sizes, and that most sliders are close to the outside of the slide, making it inconvenient to adjust quickly when the slider is idle.

[0005] This invention provides a bridge jacking construction slider, specifically including: a load-bearing slider, an extension support, a load-bearing plate, a load-bearing pressure column, and a fixed support column;

[0006] A load-bearing block is fixedly installed on the top of the load-bearing slider. Load-bearing grooves are formed on the sides of the load-bearing slider and the load-bearing block. The load-bearing slider and the load-bearing block are fitted onto the outer sides of both ends of the extension support via the load-bearing grooves. A load-bearing groove is formed on the inner side of the load-bearing slider. A load-bearing sliding column is fixedly installed on the inner side of the load-bearing groove. A load-bearing support column is fitted onto the outer side of the load-bearing sliding column. Assembly frames are fixedly installed at both ends of the top of the load-bearing slider.

Support sliders are fixedly installed on the sides of the fixed support blocks. The bottom of the support slider is fixedly connected to the load-bearing slider. The load-bearing pressure column is located between the two sets of load-bearing support plates. A load-bearing seat is fixedly installed on the top of the load-bearing pressure column. The fixed support column is fixedly installed at the bottom of the load-bearing pressure column. A pushing block is fixedly installed at one end of the bottom of the fixed support column.

[0007] Optionally, the load-bearing slider is also provided with: a load-bearing support block, a threaded support column, and a threaded sleeve block;

[0008] The load-bearing block is fixedly installed on the side of the load-bearing slider; the threaded support is set inside the load-bearing block; and the threaded sleeve is fitted on the outside of the threaded support.

[0009] Optionally, the load-bearing column is also provided with: mounting blocks, mounting shaft blocks, jacking rollers, and fixed side rollers;

[0010] The assembly support block is fixedly installed at both ends of the load-bearing column; the mounting shaft block is fixedly installed on both sides of the assembly support block; the jacking support wheel is rotatably installed at the bottom of the mounting shaft block; and the fixed side wheel is fixedly installed on the side of the mounting shaft block.

[0011] Optionally, the fixed sliding column is also provided with: a pushing bottom block and a mounting support block;

[0012] The bottom extrusion block is fixedly installed at one end of the top of the fixed sliding column; the mounting blocks are fixedly installed on both sides of one end of the fixed sliding column.

[0013] Optionally, the spring strut is also provided with: a bearing sleeve and a docking bracket;

[0014] The bearing sleeve is fitted onto the outside of the spring support, and the top of the bearing sleeve is fixedly connected to the bottom of the mounting block; the connecting bracket is fixedly installed at both ends of the bearing sleeve.

[0015] Optionally, the support slider is also provided with: a support slide frame and a preset slide groove;

[0016] The support slide frame has a pre-set groove through both sides, and the support slide frame is fitted onto the outside of the support slider through the pre-set groove.

[0017] Optionally, the load-bearing base is also provided with: assembly slots, assembly clamping blocks, bearing pads and assembly clips;

[0018] The assembly slot is opened through the side of the load-bearing base; the assembly clamp is fixedly installed at both ends of the bottom of the load-bearing base; the load-bearing pad is fixedly installed at both ends of the bottom of the load-bearing base, and the load-bearing pad is installed on the top of the load-bearing base through the assembly clamp.

[0019] Optionally, the fixed support column is also provided with: a fixed slider, a docking slide frame, and an assembly slide groove;

[0020] The fixed slider is fixedly installed at the other end of the bottom of the fixed support column; the side of the docking slide frame is provided with an assembly slide groove, and the docking slide frame is sleeved on the outside of the fixed slider through the assembly slide groove.

[0021] Beneficial effects

[0022] By assembling the slotted joints and mounting blocks, the load-bearing base can be fixedly assembled with the load-bearing pad, allowing the load-bearing pad to support the bridge structure. Simultaneously, the weight of the bridge structure presses down on the load-bearing pressure column and fixed support column, which in turn presses down on the pushing top block. This causes the pushing top block to push the corresponding pushing bottom block, while simultaneously tightening the fixed sliding column and load-bearing sleeve block. The position of the mounting shaft block can be adjusted via the docking bracket, allowing the fixed side wheel to press firmly against the side of the slide rail. This, in conjunction with the jacking rollers, enables stable jacking of the bridge. After the bridge is transported to the appropriate position and supported by the hydraulic column, the spring support column can push the load-bearing sleeve block back to its original position, adjusting the position of the fixed side wheel and disengaging it from the side of the slide rail. This facilitates rapid adjustment of the entire empty slider assembly.

[0023] Furthermore, by rotating the threaded sleeve block, the spacing between the two sets of threaded sleeve blocks can be adjusted, thereby enabling the load-bearing support block to drive the two sets of load-bearing sliders to the fixed position of the threaded support, thus adjusting the spacing between the two sets of load-bearing sliders. This allows the load-bearing sliders to assemble load-bearing pads of different sizes, and at the same time, the load-bearing sliders can drive the jacking rollers to be installed on the top of the slide, thus making the sliders suitable for use on bridges of different sizes.
