[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0015] like Figure 1-4As shown, the embodiment of the utility model provides a support with an anti-deflection temporary limiting device, including an upper support plate 1 and a lower support plate 3, the lower support plate 3 is located above the upper support plate 1, and a spherical crown plate 2 is provided at the bottom of the upper support plate 1, and ear plates 2-1 are symmetrically welded on both sides of the spherical crown plate 2, and the upper plane of the ear plate 2-1 is provided with a groove, and a limiting device 7 is clamped in the groove of the ear plate 2-1, and the limiting device 7 includes a C-shaped steel 7-1 and a bolt 7-2. The upper end protrusion of the C-shaped steel 7-1 is embedded in the groove of the ear plate 2-1, and the lower end of the C-shaped steel 7-1 is provided with a through hole, and the bolt 7-2 is inserted into the through hole of the C-shaped steel 7-1, and the lower end of the bolt 7-2 is connected to the lower support plate 3 Through threaded connection, the two limit devices 7 are symmetrically arranged about the center plane of the spherical crown plate 2, the state of the spherical crown plate 2 is kept horizontal, the upper surface of the spherical crown plate 2 is provided with a groove, the groove of the spherical crown plate 2 is equipped with a flat slide 4, the lower surface of the upper support plate 1 is welded with flat stainless steel, the flat stainless steel of the upper support plate 1 and the flat slide 4 form a sliding pair, the lower spherical surface of the spherical crown plate 2 is welded with spherical stainless steel, the top of the lower support plate 3 is provided with a concave spherical surface, and a spherical slide 5 is installed in the concave spherical surface of the lower support plate 3. The spherical slide 5 and the spherical stainless steel form a rotating pair, and the contact surface between the flat stainless steel and the flat slide 4, and the contact surface between the spherical slide 5 and the spherical stainless steel are both equipped with sealing rings 6.

[0016] The main purpose of the stepped design between the ear plate 2-1 and the spherical crown plate 2 is to enhance the connection strength and stability between the ear plate 2-1 and the spherical crown plate 2. The determination of the step height h1 requires comprehensive consideration of the mechanical properties of the material, the difficulty of processing, and the actual needs during the installation process. An appropriate step height can ensure that the ear plate 2-1 is not easily deformed or loosened when subjected to external forces, thereby more effectively transmitting and dissipating stress. The stepped design increases the contact area and bite force, improving the reliability of the connection; at the same time, it also provides a more stable support surface for the installation of the limit device 7, which is conducive to ensuring the realization of the limit function.

[0017] The spacing h2 between the upper end of the stopper 7 and the flat stainless steel plate is designed to ensure smooth relative sliding between the flat slide 4 and the flat stainless steel plate, while also preventing excessive spacing that could result in unstable installation or wobble. The size of h2 is determined based on the sliding resistance and stability requirements in actual use. An appropriate spacing h2 ensures proper functioning of the sliding pair between the flat slide 4 and the flat stainless steel plate during normal use, reducing friction and wear. It also provides flexibility for installation and adjustment, facilitating on-site operation.

[0018] Working principle: When using a support with a temporary anti-deflection limit device, fix the lower support plate 3 on the pier to ensure that the center line of the support coincides with the center line of the support on the pier. Install a temporary limit device 7 between the spherical crown plate 2 and the lower support plate 3, use the C-shaped steel 7-1 on the limit device 7 to clamp the ear plate 2-1 on the spherical crown plate 2, and fix the bolt 7-2 on the limit device 7 to the lower support plate 3, so that the spherical crown plate 2 is temporarily fixed on the lower support plate 3 to prevent it from deflecting during the installation process. Adjust the position and tightness of the limit device 7 to ensure that the spherical crown plate 2 is firmly fixed and not subject to excessive constraints. Use measuring tools to check the installation accuracy of the support and the limit device 7, including the position of the support center line, the contact between the upper support plate 1, the spherical crown plate 2 and the lower support plate 3, etc. Make necessary adjustments and tightening to the support and the limit device 7 according to the inspection results to ensure that the installation quality meets the requirements.
