Description

Technical Field

[0001] The utility model relates to the field of spherical steel bearings, and particularly to a new type of spherical steel bearing. Background Art

[0002] Spherical steel bearings approximately include components such as an upper bearing plate, a stainless steel plate, a flat / spherical slide plate, a spherical crown liner plate, a lower bearing plate, and anchor bolts in terms of structure. A pot-type spherical steel bearing for bridges is disclosed in the Chinese utility model patent with the publication number CN219260711U. It is provided with a tower plate for connecting the upper bearing plate and the upper bearing plate. Fixed bolts can squeeze the moving plate, thereby increasing the stability of the upper bearing plate and the upper bearing plate. The rubber sealing ring can increase the sealing performance between the lower bearing plate and the upper bearing plate.

[0003] In the above structure, the cross-section of the lower bearing plate is in an I-shaped structure, while the two sides below the upper bearing plate are in an L-shaped structure. The inner diameter of the bottom end of the upper bearing plate is smaller than the outer diameters of the upper and lower wide parts of the lower bearing plate, which makes it difficult to install the upper bearing plate on the lower bearing plate. For this reason, we have designed a new type of spherical steel bearing. Content of the Utility Model

[0004] To solve the technical problem that it is relatively difficult to install the upper bearing plate on the lower bearing plate, the utility model provides a new type of spherical steel bearing.

[0005] The utility model is realized by adopting the following technical solutions: A new type of spherical steel bearing includes a lower bearing. A spherical panel is arranged in the spherical groove at the top end of the lower bearing. A steel ball core is arranged on the spherical panel. A flat panel is arranged above the steel ball core. A stainless steel plate is arranged above the flat panel. A lower seat plate is installed below the lower bearing. An upper seat plate is arranged above the stainless steel plate. A support collar is arranged below the upper seat plate, and the support collar is sleeved on the lower bearing. A rubber sealing ring is pressed between the lower bearing and the lower seat plate.

[0006] As a further improvement of the above solution, a positioning groove is formed by concaving downward on the upper surface of the upper end of the lower seat plate, and a positioning protrusion matching the positioning groove is arranged at the bottom end of the lower bearing. The positioning protrusion is inserted into the positioning groove, and the lower seat plate and the positioning protrusion are connected by countersunk head bolts. When installing, the lower bearing can be quickly and initially fixed above the lower seat plate, which is convenient for subsequent installation of other components and also convenient for subsequent complete fixation of the lower bearing and the lower seat plate.

[0007] As a further improvement of the above solution, a plurality of annularly distributed docking ports are formed through the upper and lower sides of the lower seat plate, and a plurality of docking blocks matching the docking ports are arranged on the bottom surface of the lower support. The docking blocks are inserted into the docking ports and welded to each other, so that the lower seat plate and the lower support can be quickly integrated, and the arrangement of the docking blocks facilitates welding of the bottom end of the lower seat plate to it.

[0008] As a further improvement of the above solution, after the docking block is inserted into the docking port, the bottom surface of the docking block is not below the bottom surface of the lower seat plate, ensuring the flatness of the bottom end of the lower seat plate after welding, and the arrangement of the docking block facilitates welding of the lower seat plate and the lower support.

[0009] As a further improvement of the above solution, a plurality of annularly distributed insertion ports are formed in the outer ring of the bottom end of the upper seat plate, and a plurality of annularly distributed insertion blocks are arranged above the support collar. The insertion blocks are inserted into the insertion ports, and the connection between the upper seat plate and the support collar is welded, so that the upper seat plate and the support collar can be quickly fixed, and the connection between the two is larger, resulting in a larger welding area and improving the connection firmness.

[0010] As a further improvement of the above solution, three equally spaced lower fixing plates are arranged on the outer surface of the outer ring of the lower seat plate, and three annularly distributed upper fixing plates are welded on the outer surface of the support collar. Screws are arranged on the lower fixing plates, and the screws pass through the upper fixing plates and are located above them, and nuts are threadedly connected to the screws, facilitating the connection between the lower seat plate and the upper seat plate. Nuts are arranged on both the upper and lower sides of the upper fixing plate, enabling the support collar to be designed to be suspended, and then enabling the support collar to be docked with the upper seat plate, which can support the support collar and facilitate the connection between the support collar and the upper seat plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By dividing the lower support plate into two parts, namely the lower seat plate and the lower support, and dividing the upper support plate into two parts, namely the upper seat plate and the support collar, the support collar can be first placed above the lower seat plate and sleeved on the lower support, thereby facilitating the installation on the lower support plate and the upper support plate and improving the convenience.

[0013] 2. By welding the lower seat plate and the lower support through the docking blocks, the lower seat plate and the lower support can be integrated into a whole, with high connection strength, and since they are welded below, they will not be interfered by the space between the upper support plate and the lower support plate. By welding the support collar and the upper seat plate through the insertion blocks, the connection between the two is larger, resulting in a larger welding area and improving the connection firmness.

A plurality of docking blocks 21 that match the docking ports 11 are provided on the bottom surface of the lower support 2. The docking blocks 21 are inserted into the docking ports 11 and the two are welded, so that the lower seat plate 1 and the lower support 2 can be quickly connected into one body, and the setting of the docking blocks 21 facilitates welding of the bottom end of the lower seat plate 1 thereto.

[0025] After the docking block 21 is inserted into the docking port 11, the bottom surface of the docking block 21 is not below the bottom surface of the lower seat plate 1, ensuring the flatness of the bottom end of the lower seat plate 1 after welding, and the setting of the docking block 21 facilitates welding of the lower seat plate 1 and the lower support 2.

[0026] A plurality of annularly distributed insertion ports 71 are formed in the outer ring of the bottom end of the upper seat plate 7. A plurality of annularly distributed insertion blocks 61 are provided above the support collar 6. The insertion blocks 61 are inserted into the insertion ports 71, and the upper seat plate 7 and the support collar 6 are welded at the docking portion, so that the upper seat plate 7 and the support collar 6 can be quickly fixed, and the connection portion between the two is larger, resulting in a larger welding area and improving the connection firmness.

[0027] Three equally spaced lower fixing plates 13 are provided on the outer surface of the outer ring of the lower seat plate 1.
