Problems solved by technology

At present, the horizontal adjustment of the track beam support is realized by adding wedge blocks and withdrawing wedges. The actual construction is difficult and the operation process is difficult to control.
[0006] For example, the adjustment of the lateral displacement of the Shanghai maglev support is achieved by taking out and inserting the plug iron on both lateral sides, and pushing the stud base to slide on the bottom plate. The structure is more complicated, because there are wedge-shaped plates, plug iron, etc. The horizontal force is also more complicated; and only a single direction (horizontal) adjustment can be realized, and the horizontal and anisotropic adjustment can not be realized in the true sense

Abstract

The invention discloses a horizontally adjustable support. The horizontally adjustable support rotates relative to an upper support plate through a spherical crown, the spherical crown slides on a lower support plate to satisfy a large-angle gradient adjustment demand, the displacement of the upper support plate and the spherical crown during the large-angle rotation gradient adjustment is limited through a limiting baffle, and thus the structure stability and safety are guaranteed; a replaceable shaft sleeve is embedded in the upper support plate and thus the horizontal adjustment demand can be satisfied by replacing an eccentric shaft sleeve.

Description

technical field [0001] The invention relates to a bridge support and a device, in particular to a horizontally adjustable support used for connecting a bridge girder body and a bridge pier. Background technique [0002] As the key component of the bridge, the support can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure. At present, most of the bearings used in my country's railways are basin-type rubber bearings and spherical steel bearings. The rotation angle is usually ±0.02rad, and large-angle slope adjustment needs to be realized by adding wedge-shaped blocks. [0003] The rotation of the pot-type rubber bearing is realized by the compression deformation of the rubber pad. The rotation angle is usually not greater than ±0.02rad, which cannot meet the needs of large-angle rotation. The construction is difficult, the operation process is difficult to control, and due to the error...
