Description

Technical Field

[0001] The invention relates to the field of shock-absorbing components of buildings, and in particular to a fast self-resetting shock-absorbing component. Background Art

[0002] In order to reduce the impact of earthquake disasters on building structures, the design and reinforcement of existing building structures usually install energy dissipation and shock absorption devices in the building structure to dissipate the energy input by the earthquake. Common practices include adding energy dissipation supports and seismic isolation bearings. When the structure is subjected to an earthquake, the energy dissipation and shock absorption device generates a damping force to do work to consume the seismic input energy, thereby reducing the seismic response of the main structure. However, most of the energy dissipation supports currently widely used dissipate the seismic input energy through plastic deformation of the material. There is inevitable residual deformation after the earthquake, which has an adverse effect on the structure and is expensive to repair. Therefore, some scholars began to apply new rubber, springs, memory alloys, prestressed tendons and other materials to ordinary energy absorbers, and designed a type of self-resetting energy absorber that can not only dissipate seismic energy in an earthquake, but also automatically reset to the initial position. The self-resetting energy absorber is equivalent to an ordinary support when there is no earthquake, and its main function is to increase the lateral stiffness of the structure. During an earthquake, it can not only dissipate energy, but also has the performance of self-resetting after deformation, which can reduce or eliminate the residual deformation of the structure. The existing energy dissipation devices with reset function can be mainly divided into rubber reset type, memory alloy reset type, spring reset type, prestressed tendon reset type and viscous damping liquid reset type. The energy dissipation modes mainly include rubber deformation energy dissipation, memory alloy material energy dissipation, friction energy dissipation, metal plastic deformation energy dissipation, and viscous liquid flow energy dissipation.

[0003] The existing equipment has the following steps:

[0004] 1. When installing the rubber self-resetting shock-absorbing device, the installation environment, temperature, and humidity must be considered, and the cost, technicality, and difficulty of replacement are all very high.

[0005] 2. The cost of the memory alloy self-resetting shock absorbing device is relatively high and its mechanical properties are sensitive to temperature and are easily affected by external temperature.

[0006] 3. When the spring pressure overcomes the friction force provided by the friction energy dissipation device to rebound, the spring self-reset shock absorbing device provides self-reset capability, but it is easy to cause spring fatigue over time. Since the reset needs to overcome the friction force, the reset speed is slow.

[0007] 4. The prestressed tendon self-resetting shock-absorbing device is limited by the existing material properties and anchoring technology. It relies on the prestress of the steel bar to reset, but the loss of prestress during long-term placement and loading is inevitable, which affects the reset effect of the self-resetting support. In addition, compared with the memory alloy reset type and the disc spring reset type, it has the disadvantages of difficult anchoring and excessive prestress loss.

[0008] 5. The self-resetting shock-absorbing device of viscous damping fluid has limited resetting ability. After the vibration ends, there is a tendency for residual displacement to exist. The sealing process has high requirements. It is affected by materials, processing accuracy, assembly process, etc., and is prone to oil leakage, friction damage, and shortening the life of the damper. For this reason, the present invention proposes a newly designed fast self-resetting shock-absorbing component. Summary of the invention

[0009] 1. Technical issues to be resolved

[0010] In view of the deficiencies of the prior art, the present invention provides a rapid self-resetting shock-absorbing component to solve the above-mentioned problems through reasonable structural design.

[0011] (II) Technical solution

[0012] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0013] A fast self-resetting shock-absorbing component includes two connecting plates and a shell arranged between the two connecting plates, four groups of rotating devices are arranged inside the connecting plates, and a transmission rod for driving the rotating devices to rotate is arranged between the four rotating devices. The top end of the transmission rod passes through the shell and is fixedly connected to the shell above. Two annular springs are fixedly installed between the two shells, and the two annular springs are arranged on both sides of the shell.

[0014] Preferably, a vertical rod is fixedly installed on one side of the two connecting plates close to each other, and the position of the vertical rod corresponds to the position of the annular spring. The vertical rods on the upper and lower sides are respectively provided with a protrusion and a circular groove on the corresponding side, and the protrusion corresponds to the circular groove, and a small spring is sleeved on the outer side of the protrusion.

[0015] Preferably, the rotating device includes a transmission gear and two side rotating shafts arranged at both ends of the transmission gear, and a friction wheel base is provided on the side of the two side rotating shafts facing away from each other, and an inner ratchet is integrally formed on the side of the friction wheel base corresponding to the side rotating shaft, and the inner ratchet is sleeved with the side rotating shaft, and a notch is provided on the side rotating shaft, and a movable pawl is provided inside the notch, and a spring sheet is fixedly installed inside the notch, and one end of the spring sheet corresponding to the pawl is connected to the pawl, and one end of the pawl extends to the outside of the notch, and the pawl is clamped with the inner ratchet of the inner ratchet.

[0016] Preferably, the transmission rod comprises a round shaft and a gear bar, the round shaft and the gear bar are fixedly connected together, and a gear groove is provided on one side of the gear bar corresponding to the transmission gear, and the gear groove is meshed with the transmission gear.

[0017] Preferably, a friction wheel base 2 is integrally formed on the inner walls on both sides of the shell, and the position of the friction wheel base 2 corresponds to the position of the friction wheel base 1. Friction wheels are arranged inside the friction wheel base 1 and the friction wheel base 2, and the corresponding two friction wheels fit each other.

[0018] Preferably, an extrusion device for squeezing the friction wheel inside the friction wheel base 2 is provided on the outer wall surface of the shell, four plug-in cylinders are provided inside the friction wheel base 1 and the friction wheel base 2, four circular holes are opened on the friction wheel, and the circular holes are plugged together with the plug-in cylinders.

[0019] Preferably, the extrusion device includes a spring tube, an extrusion spring and a bolt. A spring tube is fixedly installed on the outer wall of the shell at two positions corresponding to the friction wheel base. An extrusion spring is arranged inside the spring tube, and a bolt is installed at the end of the spring tube.

[0020] Preferably, two corresponding rectangular blocks are fixedly mounted on the inner wall of the shell, and two semicircular grooves are formed on the rectangular blocks, and the semicircular grooves correspond to the rotating devices.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the rapid self-resetting shock-absorbing component provided by the present invention has the following beneficial effects:

[0023] 1. Compared with the existing friction-type shock-absorbing devices, the friction effect of this fast self-resetting shock-absorbing component can be guaranteed for a longer period of time and can be adjusted. The two friction wheels are tightly pressed against each other under the compression of the corresponding compression springs, which can ensure the contact of the two friction wheels for a long time; the size of the friction force when the friction wheel rotates is related to the elastic force provided by the compressed spring, and the compression of the spring can be adjusted by screwing the bolts on the outside of the device to achieve adjustable friction.

[0024] 2. The rapid self-resetting shock-absorbing component solves the disadvantage of the existing friction energy-consuming components with self-resetting function provided by springs that need to overcome the friction work when resetting, reduces the wear of the friction surface and speeds up the resetting time.

[0025] 3. Compared with the existing self-resetting shock-absorbing devices, this rapid self-resetting shock-absorbing component adopts a ratchet. When the spring is compressed, it will drive the transmission rod to move, thereby driving the transmission gear and the ratchet to rotate, and let the friction wheel rotate to consume friction energy; when the spring is reset, the pawl of the inner ratchet will not get stuck on the ratchet teeth, and will not drive the friction wheel to rotate, so that the spring does not need to overcome the friction resistance of the friction wheel during the reset process, and can be reset quickly.

DETAILED DESCRIPTION

[0033] 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.

[0034] Example

[0035] See also Figure 1-6The fast self-resetting shock-absorbing component provided by the embodiment of the present invention comprises two connecting plates 2 and a shell 1 arranged between the two connecting plates 2. Four sets of rotating devices 4 are arranged inside the connecting plates 2. A transmission rod 5 for driving the rotating devices 4 to rotate is arranged between the four rotating devices 4. The top end of the transmission rod 5 passes through the shell 1 and is fixedly connected with the upper shell 1. Two annular springs 3 are fixedly installed between the two shells 1, and the two annular springs 3 are arranged on both sides of the shell 1. The self-resetting shock-absorbing component is directly used in places where shock absorption is required, directly with concrete, I-beams, wood, etc., or used for shock-absorbing bearings. According to the placement direction, it provides a large supporting force for the horizontal or vertical direction, and converts the earthquake energy through the compression deformation energy storage and friction energy consumption of the annular spring 3 during an earthquake. When the earthquake force disappears or is less than the elastic force of the annular spring 3, the annular spring 3 quickly resets to restore the building to its initial state. During the reset process, since there is no need to overcome the friction between the friction wheels, the reset speed is accelerated, which can enable the building to better resist the subsequent earthquake force. Furthermore, a vertical rod 23 is fixedly installed on one side of the two connecting plates 2 that are close to each other, and the position of the vertical rod 23 corresponds to the position of the annular spring 3. The vertical rods 23 on the upper and lower sides are respectively provided with a protrusion and a circular groove on the corresponding side, and the protrusion corresponds to the circular groove. A small spring 24 is sleeved on the outer side of the protrusion. Such a setting ensures that the annular spring 3 is not misplaced when the device is subjected to force compression.

[0036] Furthermore, the rotating device 4 includes a transmission gear 15 and two side shafts 17 arranged at both ends of the transmission gear 15. The two side shafts 17 are each provided with a friction wheel base 10 on the side facing away from each other. The friction wheel base 10 is integrally formed with an inner ratchet 16 on the side corresponding to the side shaft 17. The inner ratchet 16 is sleeved together with the side shaft 17. A notch 18 is provided on the side shaft 17. A movable pawl 20 is provided inside the notch 18. A spring sheet 19 is fixedly installed inside the notch 18. The spring sheet 19 is connected to the pawl 20 at one end corresponding to the pawl 20, and one end of the pawl 20 extends to the outside of the notch 18, and the pawl 20 will be engaged with the inner ratchet of the inner ratchet 16.

[0037] Furthermore, the transmission rod 5 includes a circular shaft 12 and a gear bar 13, the circular shaft 12 and the gear bar 13 are fixedly connected together, and a gear groove is opened on one side of the gear bar 13 corresponding to the transmission gear 15, and the gear groove is engaged with the transmission gear 15. The device is installed in a place where shock absorption is required. When vibration occurs, the transmission rod 5 moves downward, and the gear bar 13 will move downward at this time, driving the transmission gear 15 to rotate, driving the friction wheel base 10 to rotate, and when the annular spring 3 rebounds and rotates in the opposite direction, the pawl 20 will not get stuck in the inner ratchet and cannot drive the inner ratchet 16 to rotate. In form, it is like pedaling a bicycle. Pedaling forward can make the wheel rotate, and pedaling backward will not rotate the wheel.

[0038] Furthermore, friction wheel base 2 14 is integrally formed on the inner walls on both sides of the outer shell 1, and the position of friction wheel base 2 14 corresponds to the position of friction wheel base 10. Friction wheels 9 are provided inside friction wheel base 10 and friction wheel base 2 14, and the corresponding friction wheels 9 fit together. When the friction wheel base 10 rotates, the friction wheel 9 inside the friction wheel base 10 will be driven to rotate, thereby friction is performed, thereby achieving friction energy consumption.

[0039] Furthermore, an extrusion device for extruding the friction wheel 9 inside the friction wheel base 2 14 is provided on the outer wall of the shell 1, and four plug-in cylinders 11 are provided inside the friction wheel base 10 and the friction wheel base 2 14, and four circular holes are opened on the friction wheel 9, which are plugged together with the plug-in cylinders 11.

[0040] Furthermore, the extrusion device includes a spring tube 6, an extrusion spring 7 and a bolt 8. The spring tube 6 is fixedly installed on the outer wall of the shell 1 at a position corresponding to the friction wheel base 2 14. The extrusion spring 7 is arranged inside the spring tube 6, and the bolt 8 is installed at the end of the spring tube 6. The bolt 8 supports the end of the extrusion spring 7. The setting of the extrusion spring 7 makes the two friction wheels 9 fit firmly together.

[0041] Furthermore, two corresponding rectangular blocks 21 are fixedly mounted on the inner wall of the housing 1 , and two semicircular grooves 22 are formed on the rectangular blocks 21 , which correspond to the rotating device 4 .

[0042] The fast self-resetting shock-absorbing component provided in the above-mentioned embodiment of the present invention has a reasonable structural design. Compared with the existing friction-type shock-absorbing device, the friction effect of this component can be guaranteed for a longer period of time and can be adjusted at the same time; the two friction wheels are tightly attached to each other under the compression of the corresponding compression springs, which can ensure the contact between the two friction wheels for a long time.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
