Description

Technical Field

[0001] The utility model belongs to the technical field of beam bridge supports, in particular to an anti-tilt installation spherical support. Background Art

[0002] The anti-tilt ball mount is a device used to support and fix equipment or structures, which is designed to prevent the equipment or structure from tilting during installation. It consists of a spherical base and a support seat, allowing the equipment to rotate and tilt freely in multiple directions.

[0003] In the prior art, high-speed railway bridge bearings require careful leveling during factory assembly, centering of the upper and lower bearing plates, and pre-stressing. The upper and lower bearing connecting steel plates and connecting bolts are used to connect the bearings into a whole. After the bearings are assembled, the parallelism of the upper and lower bearing plates should not be greater than 2‰ of the long side. Before installing the bearings, check whether the connection condition is normal, but the upper and lower bearing connecting plates and connecting bolts must not be loosened arbitrarily. During installation, the bottom surface of the lower bearing plate is required to be flat, and the vertical initial inclination of the lower seat plate caused by the installation should not be greater than 5‰rad in both the longitudinal and transverse directions of the bridge. However, in actual engineering applications, during the transportation, hoisting, and installation and positioning of the bearings, the connecting plates are loosened, the upper and lower seat plates are dislocated, and it is difficult to ensure the parallelism of the upper and lower seat plates. When the bearings are installed and positioned, it is impossible to judge whether the lower seat plate of the bearing is placed horizontally and whether the upper and lower seat plates are parallel, which poses a hidden danger of installation quality problems. When pouring beam concrete above the support, due to the eccentric load and insufficient formwork support strength, it is very easy for the upper seat plate to deviate and shift, failing to meet the support installation accuracy requirements and making repairs extremely difficult. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an anti-tilt mounting spherical support, which solves the problem that the connection plate is easily loosened and the upper and lower seat plates are misaligned during the positioning process of the support.

[0005] To achieve the above-mentioned purpose, according to an embodiment of the utility model, an anti-tilt installed spherical bearing is proposed, comprising a movably installed lower bearing plate assembly and an upper bearing plate assembly, a cavity is arranged between the lower bearing plate assembly and the upper bearing plate assembly, and a spherical crown lining assembly is arranged in the cavity, and a limit device with an adjustable length is also movably arranged between the lower bearing plate assembly and the upper bearing plate assembly.

[0006] Preferably, a level bubble is provided on one side of the lower support plate assembly.

[0007] Preferably, a slide plate and a sealing ring matched with the spherical cap lining assembly are provided in the cavities of the lower support plate assembly and the upper support plate assembly.

[0008] Preferably, the limiting device comprises an adjusting bolt and an adjusting sleeve which are threadedly connected to each other.

[0009] Preferably, a magnet embedded in the adjusting sleeve is provided at one end of the adjusting sleeve away from the adjusting bolt.

[0010] Preferably, a connecting device is provided between the lower support plate assembly and the upper support plate assembly.

[0011] Preferably, the connecting device comprises a connecting block, an anchor bolt and a connecting bolt threadedly connected to the connecting block, and the anchor bolt and the connecting bolt are threadedly fixed to the lower support plate assembly and the upper support plate assembly respectively.

[0012] Preferably, a lower anchor assembly is fixedly mounted on one side of the lower support plate assembly.

[0013] Preferably, an embedded component is provided on one side of the upper support plate component, and the embedded component includes an embedded steel plate and a sleeve fixed to each other.

[0014] Preferably, the upper support plate assembly and the embedded steel plate are fixed to each other by beam bottom bolts.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By setting a limit device and a connecting device, the relative distance between the adjusting bolt and the adjusting sleeve is adjusted, and the distance b between the lower support plate assembly and the upper support plate assembly is adjusted to ensure the parallelism of the upper and lower support plates. When the support top beam is cast, the limit device is removed. The device is easy to disassemble and portable and can be reused. The magnet is adsorbed on the side wall of the metal lower support plate assembly for easy positioning. The anchor bolts and the connecting bolts are respectively threadedly fixed to the lower support plate assembly and the upper support plate assembly. The connecting device limits the offset between the lower support plate assembly and the upper support plate assembly, ensuring the horizontal gap a between the lower support plate assembly and the upper support plate assembly, ensuring the alignment of the center line of the support, and preventing the support from loosening during the positioning process.

[0032] like Figure 1-Figure 3 and Figure 5 As shown, the limit device 8 includes an adjusting bolt 801 and an adjusting sleeve 802 which are threadedly connected to each other.
