Description

Technical Field

[0001] The invention relates to the technical field of building shock-absorbing dampers, in particular to a damper device for energy dissipation and shock absorption of building structures. Background Art

[0002] Energy dissipation and shock absorption of building structures refers to the design and installation of specific structural measures to reduce the impact of the vibration amplitude of the building structure under the action of earthquakes or other vibration loads on the structure. The application of dampers in building structures has enabled people to break away from the traditional concept of strengthening beams, columns and walls to improve vibration resistance. Combined with the dynamic performance of the structure, it cleverly avoids or reduces the damage to buildings caused by earthquakes and wind.

[0003] Existing building dampers usually do not have a cooling mechanism, especially friction dampers. When a friction damper is used to reduce shock to a building, there will be intense friction between the two contact surfaces, and the friction between the two contact surfaces will be used to consume external vibration energy. However, the intense friction between the two contact surfaces will cause a sharp rise in heat. If the temperature is not cooled in time, long-term high temperature may cause degradation of the internal materials of the damper, especially those used to generate the friction interface. The degradation may cause the performance of the damper to decline, reducing its effectiveness and service life. In addition, the friction strength of existing friction dampers usually needs to be manually adjusted and cannot be automatically adjusted according to the amplitude of the vibration. When an earthquake occurs, manual on-site adjustment may affect the safety of the operator. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Fig.13 , a damper device for energy dissipation and shock absorption of building structures is shown in the figure, including a base 1, two friction contact panels 3 are symmetrically arranged on the outer side wall of the upper end of the base 1, a friction plate 6 is slidably arranged between the two friction contact panels 3, and push plates 7 are arranged at both ends of the friction plate 6, a mounting member 5 is arranged on the outer side wall of the friction plate 6, and a top platform 2 is fixedly connected to the mounting member 5, and a trigger box 4 is fixedly connected to both sides of the two friction contact panels 3, a cooling groove 13 is opened between the trigger box 4 and the friction contact panel 3, a ventilation net 8 is arranged outside the cooling groove 13, and a heat conducting fin 12 is arranged inside the cooling groove 13, and an increasing friction mechanism is arranged inside the trigger box 4, and the increasing friction mechanism includes an inner slide groove 24 opened on both sides of the trigger box 4, an inner plate 14 is slidably connected to the inner side wall of the inner slide groove 24, and a tension spring 25 is fixedly connected to the inner side wall of the inner slide groove 24, and the other end of the tension spring 25 is fixed on the outer side wall of the inner plate 14, and sliding grooves 47 (such as Fig.10 As shown in the figure, the inner wall of the sliding groove 47 is slidably connected to the side plate 15, the inner wall of the sliding groove 47 is provided with a return spring 48, the other end of the return spring 48 is fixedly connected to the outer wall of the side plate 15, both sides of the inner plate 14 are fixedly connected with the pressing piece 29, the two sides of the trigger box 4 are slidably connected to the limit rod 10, both sides of the limit rod 10 are provided with a side spring 49, the other end of the side spring 49 is fixedly connected to the outer wall of the trigger box 4 (as shown in the figure). Figure 6 As shown in the figure, a plurality of limiting teeth 28 are arranged on the limiting rod 10, and slide grooves are provided on both sides of the trigger box 4. A slide plate 27 is slidably connected to the inner wall of the slide groove, and the end of the slide plate 27 is in sliding contact with the limiting teeth 28. An electric push rod 26 is fixedly connected to the outer wall of the slide plate 27, and one end of the electric push rod 26 away from the slide plate 27 is fixedly connected to the inner wall of the slide groove, and a cooling mechanism is arranged inside the trigger box 4.

[0033] In this embodiment, when an earthquake causes the entire building to vibrate, the top platform 2 and the bottom platform 1 respectively fixed on both sides of the building will respectively drive the friction contact panel 3 and the friction plate 6 to slide relative to each other, allowing friction between the two. When the two sides of the friction plate 6 rub against the two friction contact panels 3, friction will be generated, and the friction force is used to consume external vibration energy to complete the shock absorption process of the entire equipment. When the friction contact panel 3 and the friction plate 6 are performing friction shock absorption, the ventilation network 8 will naturally ventilate the cooling tank 13 to cool the thermal fins 12, thereby ensuring that the thermal fins 12 can absorb friction heat more efficiently and avoid high temperatures that affect the shock absorption effect of the entire equipment.

[0034] When the earthquake amplitude is large and causes the entire building to shake violently, the two friction contact panels 3 and the friction plate 6 will have a large sliding friction. When the friction plate 6 drives the push plate 7 to have a large relative sliding friction with the friction contact panel 3, the push plate 7 will contact the limit rods 10 on both sides of the trigger box 4 and push the limit rods 10 on both sides into the trigger box 4. When the limit rods 10 slide into the trigger box 4, the ends of the limit rods 10 will contact the pressing piece 29 and follow the first contact inclined surface of the pressing piece 29 to push the entire The inner plates 14 are pushed along the inner slide groove 24 toward the friction plate 6. When the end of the limit rod 10 contacts the first contact plane of the pressing piece 29, the inner plates 14 will make the side plates 15 on both sides contact the friction plate 6 first during the movement. When the two inner plates 14 cooperate with the friction contact panel 3 to contact the friction plate 6, the friction area is significantly increased compared with before. When the friction area increases, the friction force between each other will also increase accordingly, and the shock absorption effect will also be enhanced, thereby meeting the shock absorption effect for large-amplitude vibrations.

[0035] Example 2: Please refer to Figure 1 - Fig.13 The cooling mechanism shown in the figure includes a push rod 11 slidably arranged on both sides of the trigger box 4, and a downward pressing magnetic block 46 (such as Fig.11 As shown, tension springs 45 are provided on both sides of the downward pressing magnetic block 46, and the other end of the tension spring 45 is fixedly connected to the inner wall of the trigger box 4, and the inner wall of the inner plate 14 is provided with a plurality of jet nozzles 30 (as shown in FIG. Figure 7 As shown in the figure, the inner walls of the plurality of jet tubes 30 are all slidably connected with a pressure rod 32, and a sleeve spring 50 is sleeved on the outer wall of the pressure rod 32. A pushing magnetic plate 31 is provided at the end of the pressure rod 32, and the magnetic poles of the pushing magnetic plate 31 and the pressing magnetic block 46 are the same. The inner wall of the jet tube 30 is connected with an exhaust pipe 9, and the exhaust pipe 9 slides through to the outside of the trigger box 4. The interior of the jet tube 30 is connected with an air outlet pipe 33, and the end of the air outlet pipe 33 is connected with an air jet duct 34. The end of the air jet duct 34 away from the air outlet pipe 33 is provided with an air jet hole 16, and the air jet hole 16 penetrates into the interior of the cooling tank 13. The inner wall of the jet duct 34 is slidably connected with a baffle plate 35, and the baffle plate 35 is provided with a The baffle plate 35 has large holes 37 and small holes 38 of different sizes, and a bottom plate 36 is fixedly connected to the outer wall of the baffle plate 35. The end of the baffle plate 35 away from the small hole 38 is fixedly connected to the outer wall of the side plate 15. A water tank 19 is provided at the end of the trigger box 4. The water tank 19 is provided with a pluggable liquid filling port 20. The interior of the water tank 19 is connected with a channel 21. The inner wall of the channel 21 is connected with a plurality of telescopic tubes 40. The ends of the plurality of telescopic tubes 40 away from the channel 21 are all connected with a bottom box 39. The inner wall of the bottom box 39 is slidably connected with a trigger tube 43. The end of the trigger tube 43 close to the inside of the bottom box 39 is sealed, and the end of the trigger tube 43 away from the bottom box 39 is open.

[0036] A through hole 44 is provided inside the trigger tube 43, a pressing spring 42 is sleeved on the outer wall of the trigger tube 43, a bottom rod 41 is provided at the bottom of the trigger tube 43, the bottom rod 41 slides through to the outside of the jet channel 34, slide rails are provided on both sides of the ventilation net 8, a cleaning plate 17 is slidably connected to the inner wall of the slide rail, a return spring 18 is fixedly connected to the outer wall of the cleaning plate 17, the other end of the return spring 18 is fixedly connected to the inner wall of the slide rail, a plurality of slide rods 22 are provided on the outer wall of the cleaning plate 17, the plurality of slide rods 22 all slide through to the inside of the trigger box 4, a contact magnet 23 is provided at the end of the slide rod 22, and the contact magnet 23 is located on the positive side of the pressing magnetic block 46 (such as Fig.11 As shown), the contact magnet 23 has the same magnetic pole as the pressing magnet block 46.

[0037] When the push rod 11 moves out of the trigger box 4 and returns to its original position, the distance between the downward pressing magnetic block 46 and the pushing magnetic plate 31 will become farther, and the magnetic force will disappear at this time. At this time, under the elastic force of the sleeve spring 50, the pushing magnetic plate 31 will drive the pressing rod 32 to overcome the elastic force of the sleeve spring 50 and push into the jet tube 30. When the push rod 11 is pushed back to its original position, the push rod 11 is pushed by the push plate 7 intermittently. Therefore, under the action of the intermittent magnetic force and the elastic force of the sleeve spring 50, the pressure rod 32 will continuously perform piston flushing and suction movement in the air jet tube 30. When the pressure rod 32 performs flushing and suction movement in the air jet tube 30, the air outside the trigger box 4 will be sucked into the air jet tube 30 through the air extraction pipe 9, and then sprayed into the cooling tank 13 through the air outlet pipe 33, the small hole 38 and the air jet hole 16, so as to spray and cool the heat-conducting fins 12 (it should be noted that both the air outlet pipe 33 and the air extraction pipe 9 are provided with a one-way valve to ensure that the air extraction pipe 9 only inhales and the air outlet pipe 33 only sprays). By cooperating with the natural ventilation of the ventilation net 8, the air jet cooling of the air jet hole 16 can further cool the heat-conducting fins 12, so that the heat-conducting fins 12 can conduct heat faster, thereby improving the cooling strength of the entire cooling mechanism for the heat under large friction, and ensuring the shock absorption effect of the entire equipment.

[0038] When a severe earthquake occurs, causing the vibration amplitude of the building to further increase, the relative sliding amplitude between the friction plate 6 and the two friction contact panels 3 will further increase. At this time, the push plate 7 will further contact and push the limit rod 10 when sliding relatively with the friction plate 6, and push the limit rod 10 into the trigger box 4 for a longer distance than before. When the limit rod 10 moves a longer distance into the trigger box 4, it will contact the second plane of the down-pressing member 29 along the second contact slope of the down-pressing member 29, and push the down-pressing member 29 together with the inner plate 14 toward the friction plate 6 for a longer distance. When the inner plate 14 moves a longer distance toward the friction plate 6, in addition to the side plates 15 on both sides contacting the surface of the friction plate 6, the bottom surface of the inner plate 14 will also slide out of the trigger box 4 and contact the plane of the friction plate 6. When both the side plates 15 and the inner plate 14 contact the surface of the friction plate 6, the friction area is further increased compared with before. When the friction area increases again, the friction force between them will also increase accordingly, thereby satisfying the shock absorption effect of severe vibration.

[0039] In the above situation, when the side plate 15 contacts the friction plate 6 first and then the inner plate 14 moves toward the friction plate 6, since the side plate 15 contacts the friction plate 6 first, the baffle 35 is relatively immobile under the resistance of the friction plate 6, and the inner plate 14 will drive the jet channel 34 to move when it moves toward the friction plate 6. During the movement of the jet channel 34, the small hole 38 originally located in the jet channel 34 will move out of the jet channel 34 during the movement of the jet channel 34, and the large hole 37 will enter the jet channel 34. When the large hole 37 enters the jet channel 34, the air jet volume of the jet channel 34 will increase accordingly. During the movement of the jet channel 34, in addition to the large hole 37 replacing the small hole 38 to enter the jet channel 34, the bottom plate 36 will also contact the bottom rod 41 during the movement of the jet channel 34, and push the bottom rod 41 to allow the trigger tube 43 to overcome the pressing force. The elastic force of the compression spring 42 slides into the bottom box 39. When the trigger tube 43 is pushed into the bottom box 39, the through hole 44 originally located outside the bottom box 39 will enter into the bottom box 39. After the through hole 44 enters into the bottom box 39, the water in the water tank 19 flowing in the channel 21 will flow into the bottom box 39 through the telescopic tube 40 in succession, and then enter the trigger tube 43 through the through hole 44, and finally drip into the jet channel 34 in a small amount through the open end of the trigger tube 43. Under the above principle, the jet cylinder 30 will blow air through the jet channel 34, and the wind blown out of the jet channel 34 will mix with the small amount of water dripped from the trigger tube 43, and spray onto the heat-conducting fins 12 through the jet hole 16. The mixed water jet can further cool the cleaning plate 17 again, thereby improving the heat conduction effect of the cleaning plate 17 and ensuring that the heat under large friction can be conducted out in time.

[0040] It should be noted that, in addition to being able to naturally ventilate the cooling tank 13, the ventilation net 8 can also filter external dust to prevent dust from entering the cooling tank 13 and affecting the friction and shock absorption effect. During the reciprocating movement of the push rod 11, in addition to allowing the jet nozzle 30 to spray air, the downward pressing magnetic block 46 will also intermittently approach the contact magnet 23. Under the action of the repulsive magnetic force and the elastic force of the return spring 18, the cleaning plate 17 can also follow the slide rail to scrape and clean the surface of the ventilation net 8 to prevent the surface of the ventilation net 8 from filtering too much dust, causing the ventilation net 8 to be blocked, and affecting the ventilation and cooling effect of the ventilation net 8.

[0041] It should be noted that observing Figure 6 When the limit rod 10 is pushed into the trigger box 4, the slide plate 27 will continuously contact the limit tooth 28, but when the limit tooth 28 wants to move outward, the slide plate 27 will press against the right angle side of the limit tooth 28, so that the limit rod 10 cannot move outward. Under the action of the limit tooth 28, the limit rod 10 can only move one-way into the trigger box 4. Therefore, when the limit rod 10 contacts the lower pressing piece 29 to allow the inner plate 14 to move downward, the limit rod 10 is always in contact with the lower pressing piece 29. After the shock absorption is completed, when a large range of friction is not required, the operator can control The electric push rod 26 contracts to allow the slide plate 27 to break away from the contact with the limit tooth 28. At this time, under the elastic force of the side spring 49, the limit rod 10 will move outside the trigger box 4 and break away from the contact with the pressing piece 29. When the downward pressure of the limit rod 10 is lost, the inner plate 14 will return to the trigger box 4 under the tension of the tension spring 25 and will not contact the surface of the friction plate 6, so that the friction force of the entire device returns to its original state, avoiding long-term high friction from reducing the system's response ability to small-amplitude vibrations, and ensuring that the entire shock absorption device can reflect subtle changes in a timely and accurate manner.
