Technical Field

[0001] The utility model relates to the technical field of building shock absorption, in particular to an anti-pulling guide rail type friction pendulum support. Background Art

[0002] The pull-out-resistant guide friction pendulum bearing is a structural bearing designed based on the guide and friction principle, and its characteristic is the addition of a pull-out-resistant design. Through friction damping, this bearing reduces the vibration and displacement of the structure under earthquake or wind force, improves the earthquake resistance, and protects the safety of the bridge or building. Its pull-out-resistant design enables the bearing to withstand large horizontal and vertical loads, enhances the stability and reliability of the bearing, reduces maintenance costs, and improves economy. Due to its flexible design and applicability to various types of bridges and building structures, the pull-out-resistant guide friction pendulum bearing is of great significance in modern engineering practice and is one of the commonly used bearing types.

[0003] After searching, the announcement number: CN211228910U discloses a bidirectional guide rail friction pendulum type seismic isolation bearing with anti-pullout function, including an upper bearing plate assembly and a lower bearing plate assembly respectively connected to the upper structure and the lower structure of the building, the upper bearing plate assembly and the lower bearing plate assembly are arranged opposite to each other, an upper guide rail block is fixed on the inner side of the upper bearing plate assembly, and a lower guide rail block is fixed on the inner side of the lower bearing plate, a sliding block is arranged between the upper guide rail block and the lower guide rail block, an upper sliding groove matching with the upper part of the sliding block is provided on the upper guide rail block, and a lower sliding groove matching with the lower part of the sliding block is provided on the lower guide rail block, the upper sliding groove and the lower sliding groove are arranged in a relatively vertical direction, and the upper and lower parts of the sliding block are slidably connected with the upper sliding groove and the lower sliding groove respectively. The utility model proposes a double-direction guide rail friction pendulum type seismic isolation bearing with anti-pull-out function, which can limit the vertical displacement of the bearing, has reasonable force, simple structure, safety and reliability, and good seismic isolation effect.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3The utility model provides an embodiment: a pull-out resistant guide rail friction pendulum support, comprising two mounting plates 1, the outer walls of the two mounting plates 1 are fixedly connected with slide rails 2, a friction block 3 is slidably connected between the two slide rails 2, a limiting groove 4 is provided inside the friction block 3, a connecting frame 5 is slidably connected to the inner wall of the friction block 3, both sides of the outer wall of the connecting frame 5 are fixedly connected with limiting rods 6, the outer wall of the limiting rod 6 is slidably connected to the inner wall of the limiting groove 4, the connecting frame 5 is rotatably connected with a left-right symmetrical roller 7, and the connecting frame The lower surface of the hinged seat 8 is fixedly connected, the inner wall of the hinged seat 8 is fixedly connected to a fixed rod 19, the outer wall of the fixed rod 19 is rotatably connected to a bilaterally symmetrical connecting rod 10, and a buffer assembly 11 is arranged inside the connecting rod 10; the buffer assembly 11 includes a fixed rod 2 1101 fixedly connected inside the connecting rod 10, both ends of the fixed rod 2 1101 are rotatably connected to rollers 2 1102, the outer wall of the rollers 2 1102 is rollingly connected to the inner wall of the friction block 3, and a spring 1103 is arranged between the two fixed rods 2 1101;

[0025] Specifically, when the friction block 3 starts to slide, the spring 1103 starts to shrink. This shrinkage force acts on the roller 2 1102, causing it to roll on the inner wall of the friction block 3 instead of sliding. The coefficient of rolling friction is much lower than that of sliding friction, so this design greatly reduces the friction coefficient. As the roller 2 1102 rolls, it further drives the connecting rod 10 on the outer wall of the fixed rod 2 1101 to rise. This connecting rod 10 is connected to the connecting frame 5, and by pushing the limiting rod 6 on the outer wall of the connecting frame 5 to slide on the inner wall of the limiting groove 4, the roller 1 7 is tightly against the inner wall of the slide rail 2. In this way, the roller 1 7 rolls on the inner wall of the slide rail 2 instead of sliding, thereby further reducing the friction. This design not only reduces friction, but also improves the efficiency of the system. Through the combination of rollers and springs, the slide rail 2 and the friction block 3 can slide faster, reducing energy loss and mechanical wear. In addition, since the rolling motion of the roller is smoother than sliding, this design can also reduce the vibration and noise of mechanical components and improve the stability of the system.

[0026] Reference Figure 2 and Figure 3 A through hole 12 is provided inside the mounting plate 1, and a limit plate 13 is slidably connected inside the mounting plate 1; a clamping block 14 is fixedly connected to one side of the outer wall of the limit plate 13, and the clamping block 14 is arranged inside the mounting plate 1; a plurality of telescopic rods 15 are fixedly connected to one side of the outer wall of the limit plate 13, and a spring 2 16 is sleeved on the outer wall of the telescopic rod 15; a mounting rod 17 is slidably connected inside the mounting plate 1, and the outer wall of the mounting rod 17 is slidably connected to the inner wall of the through hole 12; a card slot 18 is provided inside the mounting rod 17, and a spring 3 19 is slidably connected inside the mounting rod 17, and both ends of the spring 3 19 are fixedly connected to the limit plate 20; a card block 21 is fixedly connected to the outer wall of the limit plate 20, and the outer wall of the card block 14 is slidably connected to the inner wall of the card slot 18;

[0027] Specifically, first, the mounting rod 17 is installed inside the building. Next, the mounting plate 1 is installed through the mounting rod 17. The mounting plate is usually a flat metal plate used to fix various equipment or furniture. There will be through holes 12 on the mounting plate, which match the mounting rod so that the mounting plate can be smoothly sleeved on the mounting rod. When the mounting rod 17 passes through the through hole 12, a series of mechanical actions will occur next. The second clamping block 21 will squeeze the spring three 19, which is an elastic element. Its function is to provide a certain resistance so that a smooth transition can be achieved when the slot 18 arrives near the first clamping block 14. At this time, the telescopic rod 15 and the second spring 16 begin to play a role. The telescopic rod has a certain degree of elasticity and can be extended or retracted when subjected to external force. The second spring provides a certain elastic force to help the telescopic rod maintain a stable position. When the first clamping block 14 contacts the inner wall of the slot 18, the cooperation of the telescopic rod and the second spring enables the first clamping block to be firmly engaged with the inner wall of the slot, thereby achieving the fixation of the mounting plate. When the clamping block 14 is fixed to the inner wall of the clamping slot 18, the reaction force of the spring 3 19 begins to appear. It pushes the clamping block 21 to contact the outer wall of the mounting plate 1, thereby enhancing the stability of the mounting plate. This reaction force is due to the restoring force generated by the spring 3 after being compressed, which makes the clamping block 2 tightly attached to the outer wall of the mounting plate, effectively preventing the mounting plate from loosening or falling off.

[0028] Working principle: when the friction pendulum bearing needs to be installed, the installation rod 17 is installed inside the building, and the installation plate 1 is installed by passing the installation rod 17 through the installation rod. When the installation rod 17 passes through the through hole 12, the spring 3 19 is squeezed by the clamping block 21, so that the clamping slot 18 reaches the vicinity of the clamping block 1 14. At this time, the clamping block 14 clamps the inner wall of the clamping slot 18 for fixing through the cooperation of the telescopic rod 15 and the spring 2 16. When the clamping block 14 fixes the inner wall of the clamping slot 18, the reaction force of the spring 3 19 pushes the clamping block 21 to contact the outer wall of the installation plate 1, so as to fix the installation plate 1.

[0029] Secondly, when the friction block 3 slides on the inner wall of the slide rail 2, the spring 1103 contracts, thereby driving the roller 2 1102 to slide on the inner wall of the friction block 3, and the roller 2 1102 drives the connecting rod 10 on the outer wall of the fixing rod 2 1101 to rise. At this time, the limiting rod 6 on the outer wall of the connecting frame 5 is pushed by the connecting rod 10 to slide on the inner wall of the limiting groove 4, so that the roller 1 7 is slid against the inner wall of the slide rail 2, thereby reducing the friction and making the slide rail 2 and the friction block 3 slide quickly.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
