Description
Technical Field
The invention belongs to the technical field of a cable saddle support for a bridge, and particularly relates to an intelligent monitoring type cable saddle support for the bridge.
Background
At present, the bridge cable saddle support mainly has two structural forms, one is that traditional cable saddle support looses as shown in fig. 5, 6, 7: the saddle mainly comprises a saddle head (14), a saddle body (15) with an inverted triangle cross section, a base (16), wherein the saddle head (14) is welded at the upper end of the saddle body (15), the saddle body (15) and the base (16) are connected through an upper strip-shaped connecting block (17) and a lower connecting block (18), a rotating pin is further arranged 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 combining cast-welding, the saddle head part is cast by cast steel, and the saddle is welded by steel plates. The cable scattering saddle support is mainly realized by adopting a cambered surface steel contact surface, has small rotation angle, is difficult to rotate and slide, has the defects of rotation flexibility and sliding adjustment, has large rotation sliding resistance, and hardly ensures that the stress distribution of the scattered cable is uniform after the scattered cable is scattered. The line contact surface is easy to damage due to the contact radian, so that the function of the scattered cable saddle is failed, and meanwhile, the line contact surface is adopted, so that the stress is transmitted to concrete greatly, and the concrete stress can be ensured only by the thickness of the lower plate. In addition, limited by the shape and structure of the saddle body, the saddle body has high height on the premise of meeting the stress distribution requirement, so that the whole saddle has high height and poor stability of the height of the center of gravity.
The other is a cable saddle support of a bridge, as shown in fig. 8 and 9: loose cable saddle support carries out bolted connection with saddle head (14), looses cable saddle support subassembly and stone anchor, looses cable saddle support subassembly and includes upper bracket board (19), middle welt (21), bottom suspension bedplate (24) and regulation positioner, form the cylinder cooperation between upper bracket board (19) and middle welt (21) and be provided with cylinder slide (23) between the two, be provided with between middle welt (21) and bottom suspension bedplate (24) plane slide (22), realize rotating through the cylinder cooperation between upper bracket board (19) and middle welt (21) to plane cooperation between middle welt (21) and bottom suspension bedplate (24) realizes the anteviation when loosing cable saddle support installation, carries out installation regulation positioner after the anteviation resets, locks loose cable saddle support operating condition. The cylindrical surface sliding plate (23) and the plane sliding plate (22) both adopt polyethylene, and high polymer materials have poor durability under special working conditions and are easy to age or have larger abrasion. The structure meets the requirement of pre-deviation of the scattered cables by adopting a method of presetting translational displacement during installation, but the scattered cables are forced to push translational reset through rotation of the scattered cable saddle support, the difficulty is higher, the later installation positioning device is more complex, the installation difficulty is higher, and the maintenance cost is higher. When the cable saddle is stressed, the cable saddle support is realized by the mutual coordination action of translation and rotation, the interference factors are more, the implementation difficulty is higher, and the stress state of the cable saddle cannot be detected and monitored.
