Embodiment 1

[0030] A multi-point support spherical bearing, such as figure 2 , image 3 As shown, it is mainly composed of an upper base plate 1, a middle base plate 2, a lower base plate 3, a lower base plate 4, a limiting plate 5 and a guide plate 6 and other components. This embodiment is a one-way movable support, the support contains two middle seat plates 2 and two lower seat plates 3, the middle seat plate 2 and the lower seat plate 3 form two rotating supports, and the vertical force of the support is composed of two shared by two rotating supports. The lower seat plate 3 is a cylinder, and the upper surface of the lower seat plate 3 is processed with a concave spherical surface for inlaying non-metallic slide plates. The lower seat plate 3 and the lower base plate 4 are mechanically connected, and the lower surface of the middle seat plate 2 is equipped with a metal Skateboard, which forms a rotating friction pair with a non-metallic skateboard. The vertical load on the upper...

Embodiment 2

[0032] A multi-point support spherical bearing, such as Figure 4-Figure 6 As shown, it is mainly composed of an upper base plate 1, a middle base plate 2, a lower base plate 3, a lower base plate 4, a limiting plate 5 and a guide plate 6 and other components. This embodiment is a fixed support. The support contains two middle seat plates 2 and two lower seat plates 3. The middle seat plate 2 and the lower seat plate 3 form two rotating supports.

Abstract

The invention provides a multi-point supporting spherical support which comprises an upper substrate, middle base plates, lower base plates and a lower substrate, at least two middle base plates and at least two lower base plates are arranged between the upper substrate and the lower substrate, the number of the middle base plates is the same as that of the lower base plates, and the lower base plates are connected with the lower substrate in a mechanical mode. One middle base plate and one lower base plate form a rotary supporting body, at least two rotary supporting bodies are arranged in parallel in a single row, and the connecting line of the arrangement centers of the rotary supporting bodies is parallel to the transverse bridge direction of the support. The idea of breaking up the whole into parts is adopted, single-point supporting of the vertical force of the support is changed into multi-point supporting, the specification of a supporting body structure is greatly reduced, a single supporting body can be directly machined through a plate, meanwhile, standardized and serialized design is adopted for the supporting body, assembly line work can be easily achieved, the manufacturing efficiency is improved, and the production cost of the support is reduced. Meanwhile, all parts of the support are mechanically connected, and maintenance and replacement of the support are facilitated.

Description

technical field [0001] The invention belongs to the technical field of bridges or building bearings, in particular to a multi-point supporting spherical bearing. Background technique [0002] Spherical bearings have the advantages of high bearing capacity, simple structure, flexible rotation and good durability, and are widely used in bridges, buildings and other fields. [0003] At present, the main structure of the commonly used spherical bearing is mainly composed of three major parts: the upper seat plate, the middle seat plate, and the lower seat plate. There are two main production methods for each part of the support. One is to directly use the plate for machining and forming. The other is casting first and then machining. [0004] Sheet metal machining and forming process is easy to purchase raw materials, low cost, less process, simple process control, short production cycle, good economical support, but it is only suitable for small tonnage spherical bearings with...
