Description

Technical Field

[0001] The utility model relates to the technical field of ball bearings, in particular to a ball bearing that is easy to adjust in height. Background Art

[0002] In bridge structures, bearings are important components that connect the superstructure and substructure of the bridge. They can reliably transmit the reaction force and deformation of the superstructure to the substructure, so that the actual stress conditions of the structure are consistent with the calculated theoretical diagram.

[0003] Once a bridge settles during use, the actual force on the entire bridge will be different from the designed force. The bridge deck elevation needs to be restored to the designed elevation by adjusting the supports. In practice, this is usually done by adding a height adjustment plate between the bridge support and the bottom of the bridge. In order to ensure that the screwing length of the bolt and the embedded sleeve remains unchanged, longer bolts need to be replaced, which increases the bending arm of the bolt and makes it more prone to deformation. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a spherical support which is easy to adjust in height.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spherical bearing that is easy to adjust in height, comprising an upper bearing plate assembly, a base plate, a height adjustment pad and a limit block assembly, a spherical crown lining assembly is arranged at the bottom of the upper bearing plate assembly, a lower swing seat assembly is arranged on the outer surface of the spherical crown lining assembly, and the height adjustment pad is fixed between the lower swing seat assembly and the base plate by the limit block assembly.

[0006] The effect achieved by the above-mentioned components is: when in use, the upper support plate assembly can be installed on the bottom of the bridge, and then the bottom plate can be installed on the support. When it needs to be raised, the beam body can be lifted first to exceed the actual height adjustment amount to a certain distance according to the actual height adjustment amount, and then the connecting bolts of the limit block assembly can be loosened, and finally the original height adjustment pad between the lower swing seat assembly and the bottom plate can be taken out, and the height adjustment pad of the corresponding height can be pushed between the lower swing seat assembly and the bottom plate, and then the limit block assembly can be used to fix it and drop the beam to complete the height adjustment process. In this way, the lifting height is lower and there is no need to replace the anchor bolts. The replacement process is simple to operate.

[0007] Preferably, the top of the upper support plate assembly is slidably connected to a planar slide, and the top of the planar slide is connected to the bridge.

[0008] The effect achieved by the above components is: by setting a flat slide plate, the contact friction between the bridge and the bearing plate assembly can be reduced. When the bridge moves left and right, it can move more smoothly on the bearing plate assembly, thereby increasing the service life of the bearing plate assembly.

[0009] Preferably, a spherical slide plate is provided at the bottom of the spherical crown lining assembly, and the outer surface of the spherical slide plate is slidably connected to the lower swing seat assembly.

[0010] The effect achieved by the above components is: by setting a spherical slide plate, when the bridge undergoes up and down circular shaking, the sliding wear of the spherical crown lining assembly and the lower swing seat assembly can be reduced, thereby increasing the service life of both. At the same time, when supporting the bridge, it does not hinder the movement of the bridge during use, thereby increasing the service life of the bridge.

[0011] Preferably, the limit block assembly is anchored at the top surface of the base plate, and the limit block assembly is fixed to the top surface of the base plate by bolts.

[0012] The effect achieved by the above components is: by anchoring the limit block assembly on the top surface of the base plate, the height adjustment pad can be easily installed and limited according to the use position, and it is convenient for the installer to operate it.

[0013] Preferably, the limit block assembly can also be anchored on the lower swing seat assembly and the side of the base plate, and the limit block assembly is fixed to the lower swing seat assembly and the side of the base plate by bolts.

[0014] The effect achieved by the above components is: by anchoring the limit block assembly to the lower swing seat assembly and the side of the base plate, the limit block assembly can be used to fix the height adjustment pad between the lower swing seat assembly and the base plate with the help of bolts according to the actual use position.

[0015] Preferably, the cross-section of the height-adjusting pad may be rectangular.

[0016] Preferably, the cross-section of the height-adjusting pad may also be hourglass-shaped.

[0017] The effect achieved by the above components is: by setting the height-adjusting pad in an hourglass shape, it can withstand a certain bending moment after being raised.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, when the spherical bearing is used to support the bridge and the bearing, the upper bearing plate assembly can be installed on the bottom of the bridge with the help of a flat slide plate, and then the bottom plate is installed on the bearing. When it needs to be raised, the beam body can be first lifted to a certain distance exceeding the actual height adjustment amount according to the actual height adjustment amount, and then the connecting bolts of the limit block assembly can be loosened, and finally the original height adjustment pad between the lower swing seat assembly and the bottom plate can be taken out, and then the height adjustment pad of the corresponding height can be pushed between the lower swing seat assembly and the bottom plate, and then the limit block assembly can be used to fix it and drop the beam to complete the height adjustment process. When the height is adjusted in this way, the lifting height is lower, and there is no need to replace the anchor bolts, and the replacement process is simple to operate.
