Description

Technical Field

[0001] The utility model belongs to the technical field of rotating bearings, and particularly relates to a small-tonnage horizontal rotating bearing. Background Art

[0002] With the construction of high-speed railways and highways, large bridges that can span rivers and railways have emerged. Restricted by the construction environment and traffic factors, the use of the rotating method for construction can better avoid the impact on the transportation of other lines.

[0003] In recent years, in order to relieve the traffic pressure of urban roads, viaducts need to be built on the basis of the original roads. Using the conventional construction technology requires full hall formwork construction on the existing roads, interrupting the traffic on the existing roads. For the main roads with heavy traffic, it will have a great impact on local travel. Therefore, to solve the above problems, piers and capping beams can be constructed parallel to the existing roads in the median strip area of the existing roads, only reducing the driving width of the existing roads without interrupting the existing road traffic, and then using the rotating method to rotate the capping beam into place.

[0004] At present, in horizontal rotation construction, due to the large weight of the rotating bridge, the tonnage is from several thousand tons to several tens of thousands of tons. The rotating ball hinge method is often used for rotation; while when only rotating the capping beam and pier, the weight of the upper structure is only a few hundred tons, which is a small tonnage compared with the rotating bridge; if the rotating ball hinge method is used to rotate the capping beam and pier, the overall mass of the steel ball hinge is too large, and the installation and positioning are relatively difficult.

[0005] In addition, since the rotating surface of the steel ball hinge is a spherical structure, when calculating the theoretical traction force, the spherical surface needs to be equivalent to a plane for calculation. Therefore, there will be a certain error between the calculated value of the traction force and the actual value, and it cannot accurately provide a theoretical basis for the rotating construction; and the steel ball hinge mainly rotates depending on the spherical surface, so the processing accuracy requirements for the spherical surface are extremely high, and the processing is relatively difficult.

[0034] Please refer to Figures 1 to 3, a small-tonnage horizontal rotation support provided by the present utility model will be described below. The small-tonnage horizontal rotation support includes a lower seat plate 1, a support body 2, a rotation structure 3, and a central positioning structure 4; the lower seat plate 1 is fixed to the base through an anchoring assembly; the support body 2 is arranged on the top of the lower seat plate 1; the support body 2 includes a plurality of rubber layers 21 and a plurality of reinforcing plates 22, and the rubber layers 21 and the reinforcing plates 22 are arranged alternately; the rotation structure 3 is rotatably arranged on the top of the support body 2; the bottom of the rotation structure 3 and the top of the support body 2 form a planar rotating pair; the central positioning structure 4 is respectively connected to the lower seat plate 1, the support body 2, and the rotation structure 3; wherein, the rotation structure 3 is rotationally matched with the central positioning structure 4.

[0035] Compared with the prior art, the small-tonnage horizontal rotation support provided by the present utility model adopts a horizontal rotation structure, which can separate the vertical rotation angle and the planar rotation, and the two are independent of each other. The planar friction pair makes the traction calculation result more accurate, and the processing accuracy of the planar rotating pair is easier to control, which can reduce the processing difficulty; compared with the steel ball hinge in the prior art, the mass of the above structure of the present application is less than that of the steel ball hinge, which is convenient for installation and positioning, reduces the installation difficulty, and improves the construction efficiency.

[0036] It should be noted that the above structure of the present application can meet the safety of the rotation construction. Compared with the steel ball hinge in the prior art, the above structure of the present application can reduce the cost of the rotation support itself.

[0037] In addition, the reinforcing plate 22 can be a steel plate, not limited to a steel plate, and can also be other plates with higher strength; in the present application, the support body 2 is arranged alternately with the rubber layer 21 and the reinforcing plate 22. On the one hand, it can improve the supporting ability of the support body 2, and on the other hand, the function of the vertical rotation angle can be realized through the deformation of the rubber layer 21; through the cooperation of the central positioning structure 4 with the lower seat plate 1, the support body 2, and the rotation structure 3, the problem of excessive vertical rotation angle can be reduced, and the rotation process can be ensured to be safe and reliable.

[0038] Exemplarily, the lower seat plate 1 and the support body 2 are integrally arranged. Specifically, the reinforcing plate 22 and the rubber layer 21 of the support body 2 are fixed together by vulcanization process, and the lower seat plate 1 and the support body 2 can also be fixed together by vulcanization process, so that the lower seat plate 1 and the support body 2 form a whole.

[0039] In some embodiments, as Figures 1 to 3 shown, the top of the support body 2 has a sealing plate 23, and a sliding plate 24 is inlaid on the top of the sealing plate 23. The sliding plate 24 and the bottom of the rotation structure 3 form a planar rotating pair.

[0040] Exemplarily, the sealing plate 23 is a steel plate. The sealing plate 23 is not limited to a steel plate and can be other plates with higher strength. By providing the sealing plate 23 on the top of the support body 2 and inlaying the sliding plate 24 on the sealing plate 23, a planar rotating pair can be formed between the sliding plate 24 and the bottom of the rotating structure 3.

[0042] Exemplarily, the bottom plate 31, the radial rib plates 32 and the circular rib plate 34 form an integral body. After pouring concrete on the top of the bottom plate 31, the overall connection strength can be improved, which is convenient for the rotating structure 3 to support and rotate the workpiece to be rotated; when the rotating structure 3 rotates relative to the support body 2, the workpiece to be rotated can be driven to rotate together.

[0043] Exemplarily, a planar stainless steel plate 311 is provided at the bottom of the bottom plate 31, and the planar stainless steel plate 311 forms a planar rotating pair with the sliding plate 24.

[0047] It should be noted that by providing the first bushing 35 on the swivel structure 3 and sleeving the first bushing 35 on the central pin 42, on the one hand, it can limit the vertical rotation angle of the swivel structure 3 and reduce the situation of excessive vertical rotation angle of the swivel structure 3, and on the other hand, it can protect the central pin 42.
