Description

Technical Field

[0001] The utility model belongs to the technical field of bridge supports, and specifically relates to a novel telescopic damping wind-resistant support. Background Art

[0002] In large-span cable-supported bridge structures, wind bearings are devices installed between the inner side of the bridge tower and the outer side of the main beam. They can reduce the lateral contact stiffness of the bridge tower and the main beam and limit the transverse swing of the bridge caused by wind loads, deflection impact loads, and seismic loads. They can withstand and transmit transverse horizontal forces and adapt to the longitudinal, transverse, and vertical displacements of the beam as well as rotation angles in all directions.

[0003] The existing wind bearing structure has the following disadvantages: (1) Conventional rigid structure wind bearings have no vibration reduction and energy dissipation function. The plane friction pair is in a non-contact state when not subjected to transverse bridge loads. The gap in the middle vibrates under the load, which causes impact between the structures. If this impact continues for a long time, it will cause damage to the wind bearing and pier, affecting the service life and safety of the bridge. (2) Wind bearings with vibration reduction and energy dissipation structures, such as disc springs, viscous dampers and other energy dissipation elements, have poor vibration reduction and energy dissipation effects due to the small wind displacement and low speed of the wind bearing, making them less effective in suppressing vibrations caused by external wind loads and conventional deflection impact loads. In addition, the structure has no pre-compression stroke or a small pre-compression stroke. After long-term use, gaps are easily generated between the bearing sliding pairs, resulting in increased tower-beam contact stiffness, affecting the safe use of the bridge structure.

[0030] In the structure constituting the above-mentioned novel telescopic damping wind-resistant support,

[0031] --like Figure 2As shown, the sealing cylinder body 2 comprises a cylinder barrel 51 fixed on the top of the lower support plate 12, one end of the telescopic column 22 is connected to the support piston 23, and the other end thereof is connected to the bottom of the upper support plate 11, and a sealing ring cover 52 is provided on the upper part of the cylinder barrel 51, and the sealing ring cover 52 is sleeved on the telescopic column 22 and connected to the external boss 54 of the telescopic column 22 through bolts or screws 53, and the number of bolts or screws 53 is multiple, and they are evenly distributed along the circumference, so as to firmly position the sealing ring cover 52 and the boss 54, and the sealing ring cover 52 is connected to the inner wall of the cylinder barrel 51 through a first sliding sealing structure 61, that is, the sealing ring cover 52 not only ensures the sealing inside the cylinder barrel 51, but also ensures that the telescopic column 22 passes through the center thereof, so as to realize synchronous lifting and retracting;

[0032] - Preferably, the sealing ring cover 52 is provided with a threaded hole 501 communicating with the interior of the sealing cylinder 2, that is, the threaded hole 501 is communicated with the annular cavity (41, 42) for filling the damping medium 43. After the filling is completed, the threaded hole 501 is sealed by a screw 502;

[0033] In order to keep the cylinder 51 clean, an annular plate 21 is provided at the opening of the cylinder 51. The material is rubber or polyurethane. The annular plate 21 is sleeved on the telescopic column 22 and can be connected to the opening edge of the cylinder 51 and the telescopic column 22 respectively through a screw or a hoop.

[0034] The separation ring in the sealing cylinder 2 is placed in the annular space between the telescopic column 22 and the cylinder 51. The separation ring can be arranged in various forms, such as Figure 2 As shown, the separation ring is a first flange 20 disposed outside the telescopic column 22, and the first flange 20 is connected to the inner wall of the cylinder 51 through a second sliding sealing structure 62, that is, the separation ring and the telescopic column 22 are an integrated structure, which avoids bolt positioning and improves the internal structure strength;

[0035] - Preferably, if Figure 1 As shown, the sealing cylinder body 2 is a split structure, which includes a lower cylinder barrel 71 integrally formed with the top of the lower support plate 12 and an upper cylinder barrel 73 connected to the lower cylinder barrel 71 through a plurality of bolts 72. The separation ring in the sealing cylinder body 2 is a second flange 74 arranged on the inner side of the lower part of the upper cylinder barrel 73. The second flange 74 is connected to the outer wall of the telescopic column 22 through a third sliding sealing structure 63. The sealing cylinder body 2 adopts a split structure, which is convenient for processing and manufacturing, and is also convenient for combined installation and maintenance and replacement, and has better assembly practicality.

[0036] ——The support piston 23 is connected to the inner wall of the sealing cylinder 2 through a fourth sliding sealing structure 64. The fourth sliding sealing structure 64 includes a plurality of dynamic sealing support rings 81 and / or dynamic sealing elastic rings 82. The dynamic sealing support rings 81 or the dynamic sealing elastic rings 82 are installed outside the support piston 23 or in the annular groove of the inner wall of the sealing cylinder 2. The sliding sealing structure must ensure sufficient structural strength and achieve mutual sliding sealing effect. The dynamic sealing support rings 81 and the dynamic sealing elastic rings 82 can effectively balance the rigid support and elastic sealing to achieve a long-term and stable sliding sealing effect. The first, second and third sliding sealing structures in this patent can all adopt the combination of the above-mentioned dynamic sealing support rings 81 and / or dynamic sealing elastic rings 82;

[0037] ——As a preferred embodiment, one or more first elastic bodies 91 are arranged between the support piston 23 and the bottom of the sealing cylinder 2. The first elastic body 91 is a rubber spring made of polyurethane or a spiral spring 911 made of metal. The two ends of the rubber spring or the metal spring 911 are respectively connected to the bottom of the support piston 23 and the bottom of the sealing cylinder 2 through positioning pins 912. Through the expansion and contraction deformation of the first elastic body 91, effective support or traction is provided for the support piston 23. Especially in the shock absorption process, it can play a damping effect on the support piston 23, avoid the piston expansion and contraction range is too drastic, and reduce the impact of vibration on the inside of the support;

[0038] The first elastic body 91 may also be a composite structure of a rubber spring with an internal helical spring, which has better elastic deformation performance and can withstand long-term repeated expansion and contraction stress;

[0039] ——Furthermore, one or more second elastic bodies 92 are arranged between the support piston 23 and the bottom of the sealing cylinder body 2. The second elastic body 92 includes a groove body 921 arranged at the bottom of the support piston 23 or the bottom of the sealing cylinder body 2. A disc spring or a leaf spring 922 is arranged in the groove body 921. A baffle 923 is arranged on the outside of the disc spring or the leaf spring 922. A limit plate 924 is arranged in the middle of the outer side of the baffle 923. The inner side of the limit plate 924 is connected to the support piston 23 or the sealing cylinder body 2 through a screw 925. The screw 925 penetrates the baffle 923. A limit groove 926 corresponding to the groove body 921 is arranged at the bottom of the sealing cylinder body 2 or the bottom of the support piston 23. The middle part of the limit groove 926 is used to accommodate the limit plate 924, and the two sides of the limit groove 926 are used to compress the baffle 923 to bear the force.

[0040] That is, during the relative compression process between the support piston 23 and the sealing cylinder 2, the first elastic body 91 is always under stress. When the baffle 923 of the second elastic body 92 contacts the bottom of the sealing cylinder 2, the second elastic body 92 starts to work under stress. The progressive working mode of the two realizes the combined stiffness change effect of the wind-resistant support, further improving the shock absorption and buffering performance.

[0041] The limiting plate 924 of the second elastic body 92 is located at the center of the baffle 923, and the area of ​​the baffle 923 is smaller than that of the limiting plate 924. After the baffle 923 contacts the bottom of the sealing cylinder 2, it is equivalent to the first compression stroke L1. After the limiting plate 924 is accommodated in the limiting groove 926, the support piston 23 continues to compress, and the baffle 923 pushes the disc spring or leaf spring 922 to be stressed, providing damping support for the support piston 23. When the bottom of the support piston 23 contacts the bottom of the sealing cylinder 2, the second compression stroke L2 is completed. In the above two compression strokes, the support is stressed to different degrees, so the effect of combined stiffness is obtained. Different compression strokes and stress stiffness can also be combined according to different tower beam stress conditions to meet the different stiffness requirements of the bridge structure under vehicle deflection load, wind load and earthquake load conditions;

[0042] ——As a preferred embodiment, the end of the telescopic column 22 is connected to the upper support plate 11 or the lower support plate 12 through the spherical cap lining plate 10, and the end surface of the telescopic column 22 is provided with a spherical surface groove 100 that matches the spherical cap lining plate 10, that is, a friction pendulum composed of a spherical cap and a spherical surface is installed between the telescopic column 22 and the support plate, which has a better shock-absorbing and isolating effect and is also convenient for the technical transformation of the existing wind-resistant support;

[0043] ——A spherical friction pair 101 is arranged between the spherical groove 100 and the spherical crown lining plate 10, and a plane friction pair 102 is arranged between the spherical crown lining plate 10 and the upper support plate 11 or the lower support plate 12. The friction pendulum structure has a relatively good steering and deflection effect, further enhancing the seismic isolation performance of the wind-resistant bearing. The new bearing operates safely and stably, and the working cycle is significantly extended;

[0044] ——In order to enhance the bonding strength and stability of the friction pendulum structure, a connecting shaft 103 is arranged at the center of the spherical cap liner 10 and the spherical groove 100, an axial hole is arranged at the center of the spherical groove 100, a through hole with a sinking step is arranged at the center of the spherical cap liner 10, the connecting shaft 103 penetrates through the through hole and is inserted into the axial hole, and the end cap of the connecting shaft 103 is placed on the sinking step, that is, the spherical cap liner 10 and the spherical groove 100 have a kinematic integrated type, spherically slide against each other, and are locked longitudinally by the connecting shaft, so as to avoid the problem of the two being separated from each other during the movement of the telescopic column 22, and the spherical cap liner 10 and the telescopic column 22 are more tightly connected;

[0045] ——A movement gap is set between the connecting shaft 103 and the through hole and the shaft hole. The contact surface between the end cap of the connecting shaft and the sinking step is a spherical surface. A spherical friction pair 101' is set between the two. The movement gap ensures that there is enough slip between the spherical cap liner 10 and the spherical groove 100 of the telescopic column 22 to obtain a shock-absorbing and isolating effect;

[0046] In other embodiments, according to the actual application conditions, the upper support plate 11 and the lower support plate 12 are both provided with anchoring components for positioning and connecting with the beam body and the pedestal respectively. The anchoring components generally include a sleeve a1, an anchor rod a2 and a positioning bolt a3, and are fixed to the upper support plate 11 and the lower support plate 12 respectively through the sleeve a1 and the positioning bolt a3.
