[0001] The invention relates to the technical field of bridge bearings, and in particular to a method for installing a jacking bearing in a limited space. Background Art

[0002] At present, bridge bearings are arranged between the superstructure and the piers of the bridge. Their purpose is to transmit the supporting reaction force of the superstructure, including the vertical and horizontal forces caused by dead loads and live loads; at the same time, to ensure that the structure can deform freely under the influence of live loads, temperature changes, concrete shrinkage and creep, so that the actual stress conditions of the upper and lower structures conform to the static diagram of the structure.

[0003] In the prior art, when the support needs to be transported to the bottom of the steel beam and the fixed pier so that the steel beam and the fixed pier can be fixed, four pulleys are usually installed on both sides of the steel beam, and chains are installed inside the pulleys, so that one end of the four chains is fixed to the four corners of the support, and the other ends of the four chains need to be pulled by staff, and the support also needs to be supported by staff. Since the installation of the support is carried out at high altitude and the support is transported by staff, the safety of the staff cannot be well guaranteed, which makes the risk too high. Summary of the invention

[0004] Based on the existing technical problems of bridge bearings, the present invention proposes a method for installing a jacking bearing in a limited space.

[0005] The present invention proposes a method for installing a jacking bearing in a limited space, comprising the following steps: first, a supporting mechanism is installed on the top of a fixed pier, and tension mechanisms are installed on both sides of the supporting mechanism on the top of the fixed pier, and the tension mechanisms are positioned directly below a connecting beam, a transmission mechanism is installed between the supporting mechanism and one of the tension mechanisms, and fine-tuning mechanisms are installed on the other two sides of the supporting mechanism on the top of the fixed pier.

[0006] Step two, grind the bottom of the steel beam, and then use the tension mechanism to pull the support adjustment plate to the transmission mechanism, so that the transmission mechanism transfers the support adjustment plate to the vicinity of the support mechanism, and when transporting the support adjustment plate, the mechanical arm on the fine-tuning mechanism supports the support adjustment plate, and the support adjustment plate moves more smoothly. When the support adjustment plate arrives near the support mechanism, the tension mechanism pulls the support adjustment plate to the third hydraulic cylinder on the support mechanism, and then uses the third hydraulic cylinder to drive the support adjustment plate to be fixed to the bottom of the steel beam.

[0007] Step 3: Fix the third threaded shaft on the tension mechanism inside the second through holes at the four corners of the top of the support, then each second connecting hook on the tension mechanism hooks the top connecting block of the third threaded shaft, and then start the four second motors on the tension mechanism, so that the support can be pulled up, and through the mutual cooperation of the four second motors, the support can be moved directly under the steel beam. Before the four second motors drive the support to move, the mechanical arms on the four fine-tuning mechanisms move to the four corners of the support, so that the four mechanical arms hold the support, so that the support is not easy to shake when moving;

[0008] Step 4: When the four second motors on the pulling mechanism drive the support to move toward the bottom of the steel beam, when the support reaches the top of the conveying plate on the transmission mechanism, the four second motors drive the support to be placed on the top of the conveying plate, so that the conveying plate can transport the support to the position closest to the bottom of the steel beam, and the support can be transported more quickly and safely through the transportation of the conveying plate;

[0009] Step 5: When the support is transported to the nearest position of the steel beam through the conveyor plate, the four second motors, the mechanical arms and the infrared detectors are started to cooperate with each other, so that the support reaches the top of the four second rubber pads on the third hydraulic cylinder directly below the steel beam, and then the four third threaded shafts are removed, and the third hydraulic cylinder is fixed to the bottom of the four second rubber pads, so that the third hydraulic cylinder drives the support to move upward, so that the second through hole on the top of the support enters into the first bolt at the bottom of the support adjustment plate, and then the support is fixed to the bottom of the support adjustment plate through the bolt cap;

[0010] Step six: Then a positioning column is fixed inside the second through hole at the bottom of the support, and then the supporting force is formed alternately through the connecting beam and the temporary piers on the supporting mechanism, so that the third hydraulic cylinder and the temporary pier are disassembled in turn, so that the positioning column is embedded in the third through hole, and then the third through hole is grouted, so that the steel beam is fixed on the top of the fixed pier without shaking or moving.
