Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance, and particularly relates to a dust-proof cover device for bridge bearings. Background Art

Its function is to transfer the upper load of the bridge and building structure to the pier through the bearing, and at the same time ensure the required force, displacement and rotation of the structure. The dust-proof work of the bridge bearing is also essential. Therefore, the dust-proof cover of the bridge bearing plays a very important role. However, the existing dust-proof covers for bridge bearings have the following problems:

[0003] (1) The existing dust-proof covers for bridge bearings are basically of an integral structure, and the material of the dust-proof cover is polyurethane (transparent). When exposed to natural conditions for a long time, it is easy to age, become brittle and crack. At present, there have been many cases of brittle cracking of the dust-proof covers on the Guangqing and Guangzhou East Ring Intercity since their opening and operation.

[0004] (2) For the existing dust-proof covers for bridge bearings, after being sleeved around the bridge bearing, they are fixed with a pressure strip and screws. The replacement of the "damaged dust-proof cover" in the later stage will become very complicated and difficult, and it also wastes a lot of time, thus affecting the work efficiency.

[0005] (3) The dust-proof cover is integrally sleeved around the bearing and fixed with screws. When checking, the whole dust-proof cover needs to be removed to fully check the bearing. After the check, it has to be reinstalled. The disassembly is difficult, which affects the inspection efficiency and increases the maintenance cost. Frequent replacement causes a large maintenance cost, and at the same time, the disassembly and inspection are difficult.

[0006] Therefore, it is necessary to design a dust-proof cover device for bridge bearings that is easy to disassemble and assemble, which is convenient for installation and daily detachable maintenance, thereby improving the service life of the dust-proof cover.
