Description

Technical Field

[0001] The invention belongs to the technical field of loose-cable saddle bearings for bridges, and in particular relates to an intelligent monitoring type loose-cable saddle bearing for bridges. Background Art

[0002] At present, there are two main structural forms of bridge loose cable saddle bearings. One is the traditional loose cable saddle bearing such as Figure 5 , 6 7: It mainly includes a saddle head (14), a saddle body (15) with an inverted triangle cross section, and a base (16). The saddle head (14) is welded to the upper end of the saddle body (15). The saddle body (15) and the base (16) are connected by an upper connecting block (17) and a lower connecting block (18) in a long strip shape. A rotating pin is also provided between the upper connecting block (17) and the lower connecting block (18). A linear contact surface is formed between the saddle body (15) and the upper connecting block (17). The structure adopts a mixed structure of casting and welding. The saddle head part is cast with cast steel, and the saddle is welded with steel plates. The structure of the loose cable saddle support is mainly realized by a curved steel contact surface. It has a small rotation angle, is difficult to rotate and slide, lacks in rotation flexibility and sliding adjustment, has a large rotation and sliding resistance, and is difficult to ensure that the loose cable stress is evenly distributed after the cable is loosened. The above-mentioned linear contact surface is easy to be damaged due to the contact arc, which leads to the failure of the cable saddle function. At the same time, the linear contact surface transmits a large stress to the concrete, and the lower plate needs to be thick to ensure the concrete stress. In addition, due to the limitation of the saddle shape structure, the saddle height is large under the premise of the force distribution requirements, which makes the entire saddle height relatively high, and the center of gravity is high and the stability is poor.

[0003] The other is the loose cable saddle support of the bridge, such as Figure 8 , 9As shown: the loose cable saddle support is bolted to the saddle head (14), the loose cable saddle support assembly is anchored to the cushion stone, and the loose cable saddle support assembly includes an upper support plate (19), an intermediate lining plate (21), a lower support plate (24) and an adjustment and positioning device. The upper support plate (19) and the intermediate lining plate (21) form a cylindrical fit and a cylindrical slide plate (23) is arranged between the two. A plane slide plate (22) is arranged between the intermediate lining plate (21) and the lower support plate (24). The rotation is realized by the cylindrical fit between the upper support plate (19) and the intermediate lining plate (21), and the pre-biasing of the loose cable saddle support during installation is realized by the plane fit between the intermediate lining plate (21) and the lower support plate (24). After the pre-biasing is reset, the adjustment and positioning device is installed to lock the working state of the loose cable saddle support. The cylindrical slide plate (23) and the plane slide plate (22) of this structure are both made of polyethylene. The durability of polymer materials under special working conditions is poor and they are prone to aging or wear. This structure meets the pre-bias requirement of the cable by using a preset translation displacement method during installation. However, after the cable is stressed, the cable saddle support is rotated to push the cable saddle back to its original position, which is difficult. In addition, the later installation of the positioning device is more complicated, which makes installation more difficult and the maintenance cost higher. When the cable saddle is stressed, the cable saddle support is realized by the coordinated movement of translation and rotation, which has many interference factors and is difficult to implement. In addition, it is impossible to detect and monitor the stress state of the cable saddle. Summary of the invention

[0004] In view of this, in order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide an intelligent monitoring type bridge cable saddle bearing so that the bridge cable saddle bearing has the advantages of safety, reliability, flexible rotation, reasonable stress diffusion, automatic lubrication of the rotating pair, good durability, easy installation and adjustment, and convenient maintenance in application, so as to achieve the purpose of having intelligent health monitoring function.

[0006] Furthermore, it also includes an angle sensor arranged between the support top plate and the support bottom plate, which measures the rotation angle of the support top plate relative to the support bottom plate to monitor, transmit and store the rotation data when the cable saddle support assembly is subjected to vertical load.

[0007] Furthermore, the embedded component includes an embedded plate and a plurality of anchor bolts arranged on the embedded plate, and each of the anchor bolts is embedded in the pier to improve the strength of the embedded component.

[0008] Furthermore, the support cylindrical slide plate and the support guide slide plate are both made of metal alloy materials or polymer materials, including copper and copper alloys, aluminum and aluminum alloys, modified polytetrafluoroethylene, modified ultra-high molecular weight polyethylene, PET, nylon, polyester, etc., but not limited to the above materials, so as to improve the durability of the loose cable saddle support, provide a stable and small friction coefficient, solve the durability problem of the polymer sliding pair and the defect of large rotational sliding resistance of the traditional loose cable saddle support.

[0009] Furthermore, it also includes an automatic filling device arranged in the loose cable saddle, and a plurality of oil guide grooves are evenly arranged on the side of the support cylindrical slide toward the support bottom plate, and each oil guide groove is connected to the automatic filling device through a pipeline, providing the function of automatically replenishing lubricating material, thereby solving the maintenance difficulty of traditional loose cable saddle supports.
