Belt conveyor support The working principle is to achieve vertical rotation of the beam through elastic compression of the rubber, and to ensure the horizontal displacement of the beam through the shear deformation of the rubber block. Therefore, for sliding bearings, there is no difference between fixed bearings and moving bearings. Since its horizontal displacement is achieved through the shear deformation of the rubber, the allowable horizontal displacement is small, suitable for small and medium span highways, urban bridges and railway bridges. For standard spans less than 20m bridges, generally can be used Belt conveyor support 。 Belt conveyor support Can be divided into rectangular and circular types. Circular disc Belt conveyor support Mainly used for circular pier bridges. Belt conveyor support The type and height should be determined according to the actual displacement and reaction force of the bearing. Belt conveyor support Should be installed as horizontally as possible. When inclined installation is required, the longitudinal slope should be less than or equal to 2%.

(1) Performance: Belt conveyor support It is made of multiple layers of rubber sheets and thin steel plates embedded and bonded under certain pressure, temperature and time. It has sufficient vertical stiffness to withstand vertical loads, can reliably transfer the reaction force from the upper part of the beam to the pier, and has good elasticity to adapt to the rotation of the beam end; and has a large shear deformation to meet the horizontal displacement of the beam structure.

(2) Features: Belt conveyor support It has been widely used in bridge construction, hydropower projects, earthquake-resistant buildings, etc. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation; saving steel, low price; convenient maintenance and replacement, low product building height, which is conducive to bridge design and cost reduction; good seismic isolation effect, which can reduce the impact of live load and seismic force on buildings.

Belt conveyor support Maintenance:

1, Belt conveyor support Regular inspection and maintenance should be carried out during each use.

2. Check Belt conveyor support And whether the upper and lower connecting parts are damaged, whether the bolts are cut or loose, and whether there are cracks in the welds.

3. Check if there is dust in the dust cover and remove the dust.

4. Check the rubber sealing ring for cracks and aging.

5. Rotate the fixing nut, clean it, and re-oil it to prevent rust.

6. Check Belt conveyor support The height change itself. This change reflects the wear of the polytetrafluoroethylene sheet. When the height change exceeds 4mm, overhaul should be carried out.
