Description

Technical Field

[0001] The utility model relates to the technical field of fixed spherical steel supports, in particular to a corrosion-resistant fixed spherical steel support. Background Art

[0002] As we all know, fixed spherical steel bearings are one of the important key components for bridge bearing and sliding. Their stable operation directly affects the safety of bridge operation. At present, fixed spherical steel bearings are generally made of low-carbon alloy steel, and the exposed metal surface is painted for corrosion protection. The total life of its anti-corrosion effect is generally up to many years, and then it needs to be re-painted for corrosion protection.

[0003] In real life, paint peeling caused by friction or collision needs to be repaired. If the repair is not timely, external moisture will adhere to the surface of the fixed spherical steel bearing, especially the surface of the spherical steel liner in the middle of the fixed spherical steel bearing. The end face of the spherical steel liner is inside the base of the spherical steel liner, which is not convenient for repainting. External moisture adheres to the end face of the spherical steel liner, which will reduce its corrosion resistance and thus reduce its service life. Most corrosion-resistant fixed spherical steel bearings are not equipped with devices to isolate the spherical steel liner from external moisture, so their practicality is not very good and there is room for improvement.

[0022] 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.

[0023] See also Figure 1-5 The utility model is a corrosion-resistant fixed spherical steel support, comprising a lower support seat 1 and an upper support seat 2. A base 10 is provided in the middle of the lower support seat 1, an arc-shaped wear-resistant plate 11 is installed on the upper part of the base 10, a spherical steel liner 12 is placed on the upper part of the arc-shaped wear-resistant plate 11, and the arc-shaped wear-resistant plate 11 can reduce the friction between the base 10 and the spherical steel liner 12. An upper wear-resistant plate 13 is placed on the upper part of the spherical steel liner 12. The upper part of the upper wear-resistant plate 13 is in contact with the lower part of the upper support seat 2, which is used to reduce the friction between the spherical steel liner 12 and the upper part of the lower support seat 1. A first sealing seat 3 is welded on the upper support seat 2 to block external moisture. A mounting groove 4 is provided inside the first sealing seat 3, and a sealing device 5 is installed inside the mounting groove 4. A second sealing seat 6 is provided at the lower part of the upper support seat 2 to block external moisture. Another mounting groove 4 is provided at the lower part of the second sealing seat 6, and is installed together with the upper part of the sealing device 5. The sealing device 5 is used to seal the area between the first sealing seat 3 and the second sealing seat 6 to prevent external moisture from adhering to the spherical steel liner 12 in large quantities, thereby reducing the corrosion resistance of the spherical steel liner 12.

[0024] A sealing ring 7 is provided in the middle of several mounting grooves 4, and a sealing groove 8 is provided on the upper and lower parts of the sealing device 5, and they are all snap-connected with the corresponding sealing ring 7. By installing the sealing ring 7 in the mounting groove 4, the two cooperate to form a mountain-shaped route. When external moisture flows on the mountain-shaped route, it will be blocked by the side wall of the sealing ring 7, which improves the moisture blocking effect to a certain extent. Combined with the sealing device 5 installed in the mounting groove 4, external moisture is blocked from passing through between the mounting groove 4 and the sealing device 5.

[0025] The corners of the upper part of the first sealing seat 3 are set in an arc shape. When a large amount of external moisture gathers on the side walls of the sealing device 5 to form water droplets, the water droplets flow downward to the upper part of the first sealing seat 3 and flow along the side walls of the arc to the outer side walls of the first sealing seat 3, so that they will not gather for a long time at the contact part between the top of the first sealing seat 3 and the sealing device 5, thereby avoiding water droplets from penetrating into the mounting groove 4 from the connection part between the two. Several drainage holes 9 are provided at the lower part of the first sealing seat 3, and all of them pass through the mounting groove 4. Several drainage holes 9 are set in an inclined shape. When the corrosion-resistant fixed spherical steel support is used for a long time and a gap appears at the contact part of the sealing device 5 and the first sealing seat 3, external moisture enters the mounting groove 4 through the gap between the two, and will flow to the outside along the inclined drainage holes 9, thereby avoiding moisture accumulation in the mounting groove 4, further improving the service life of the corrosion-resistant fixed spherical steel support.

[0026] Several first mounting holes are provided around the lower support base 1 , and several second mounting holes are provided around the upper support base 2 .

[0027] A gap is provided between the inner wall of the sealing device 5 and the base 10 , and the distance between the two is large enough to facilitate the installation of the sealing device 5 by the staff.

[0028] In summary, when using the corrosion-resistant fixed spherical steel support, the staff applies glue or other sticky substances on the lower part of the sealing device 5, and then inserts the lower part of the sealing device 5 into the installation groove 4 of the first sealing seat 3, so that the sealing ring 7 is stuck in the sealing groove 8 of the sealing device 5, and then applies glue or other sticky substances on the upper part of the sealing device 5, grabs the upper support seat 2 and moves it to the upper part of the sealing device 5, aligns the second sealing seat 6 with the upper part of the sealing device 5, and moves downward to align the sealing device 5 with the second sealing seat 6. The mounting grooves 4 are snapped together until the top of the sealing device 5 is tightly against the top wall of the mounting groove 4 of the second sealing seat 6. At this time, a sealing wall is formed between the first sealing seat 3, the sealing device 5 and the second sealing seat 6 between the upper support seat 2 and the lower support seat 1, which blocks the external moisture and keeps the arc-shaped wear-resistant plate 11, the spherical steel liner 12 and the upper wear-resistant plate 13 and other devices dry. The moisture on the surface of the sealing device 5 forms water droplets that flow onto the first sealing seat 3 and eventually slide along the arc-shaped end face to the outside of the first sealing seat 3.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
