Description

Technical Field

[0001] This utility model relates to the field of bridge bearing replacement technology, and in particular to a convenient tool for replacing bridge bearings. Background Technology

[0002] Bridge bearing replacement tools are equipment or tools used for the quick and efficient replacement of bridge bearings. These tools offer advantages such as precise lifting, efficient drilling, flexible transportation, accurate installation, easy operation, adaptability to different working conditions, and improved construction efficiency and safety. Jacks are key equipment used for lifting the bridge structure, providing powerful lifting capabilities to ensure sufficient working space during bearing replacement. Jacks typically operate on hydraulic or mechanical principles, offering high-precision control to ensure the safety and stability of the bridge structure.

[0003] The prior art disclosed in CN215164813U, a bridge bearing replacement device, belongs to the technical field of bridge maintenance equipment. It includes a hydraulic cylinder and two support plates, each located at one end of the hydraulic cylinder. The outer end faces of the support plates are respectively used to abut against the bottom of the beam and the top cap of the pier. Each support plate has at least two movable and fixed claws that abut against the sidewalls of pre-set grooves on the bottom of the beam or the top cap of the pier to limit the position of the support plate. Before construction, this invention pre-defines or opens pre-set grooves on the bottom of the beam and the top cap of the pier. During construction, the two support plates are respectively secured to the pre-set grooves by the claws, limiting their horizontal movement and completely eliminating the risk of horizontal slippage during operation, greatly improving operational safety. Furthermore, by tilting the support plates, it can also be used for beam types with uneven bottoms, such as fish-belly beams, significantly increasing its applicability.
