Description
Technical Field
The invention relates to the technical field of shock absorption supports, in particular to a self-resetting inhaul cable shock absorption support.
Background
Earthquake disasters are natural disasters with great influence on human society, and bridges and buildings bear huge loads instantaneously during earthquake, so that the bridges and the buildings are severely vibrated, destroyed and collapsed. The bridge support is a key component for connecting the upper structure and the lower structure of the bridge, in order to ensure the life and property safety of people, in a high-intensity earthquake area, the design of shock absorption and isolation by adopting the support is an important means for ensuring the earthquake-resistant performance of the structure, and the investigation of shock damage and related research show that in order to control the residual displacement of the structure after the earthquake, the restorability of the structure is improved, the social and economic influence caused by earthquake disasters is reduced, and the shock absorption and isolation support should have large displacement adaptive capacity, energy consumption buffering capacity, and good limiting capacity and self-resetting capacity.
The traditional supports such as basin-type supports, spherical supports and rubber supports are widely applied due to high vertical bearing capacity and stable support performance, but the supports lack of displacement restraining devices, so that beam falling disasters are easy to happen under an earthquake, and the application of the supports in a high-intensity area of the earthquake is restricted; the traditional friction pendulum vibration reduction and isolation support has better self-resetting capability and friction energy consumption capability, the self-resetting function is to reset the beam body by means of the weight of the beam body, the beam falling phenomenon can occur in the normal operation stage, and the structure is stressed disadvantageously;
the patent application number 201921222276.9 provides a inhaul cable shock absorption support, a inhaul cable component is added on the basis of a traditional support, the support is not constrained in a normal displacement state, under the action of an earthquake, the support can be allowed to deform greatly, the internal force of the earthquake is reduced, reasonable and controllable support displacement is realized, the occurrence of beam falling disasters is effectively prevented, but the inhaul cable shock absorption support lacks a self-resetting function, and after the earthquake, the residual displacement of the support is larger;
the patent application number is 202010400684.X provides a waveform cable superelastic self-resetting shock mount and the patent application number is 202220467742.5 provides a hoop waveform cable self-resetting shock mount, and two kinds of cable shock mounts make the mount possess self-resetting function performance through increasing resetting means or elastic element on original cable subassembly. The self-resetting inhaul cable damping support needs to realize two functions, namely an inhaul cable limiting damping function; the other is a self-resetting function, and although the two supports solve the problem of self-resetting theoretically, the expected effect is difficult to achieve in practical application, and the specific reasons are as follows:
according to industry or local standards, the design bearing capacity F of the inhaul cable limiting and damping function is 40% of the vertical force N of the support, and F1=0.4N; the self-resetting function only needs to overcome the friction force F of the support, according to the related industry standard, the friction coefficient mu=0.03-0.05 of the support, the design bearing capacity F2=f=μN=0.03-0.05N of the self-resetting function, and the relation of 8-13 times exists between F1/F2=8-13 according to the relation;
the existing self-resetting inhaul cable support combines inhaul cable limiting shock absorption function and self-resetting function into a whole, namely the existing inhaul cable is used as a shock absorption limiting inhaul cable, and is also used as a self-resetting inhaul cable, F=0.4N design bearing capacity is adopted to select inhaul cable diameter and number, F=nP (N is the number of steel wire ropes, and P is the minimum breaking force of the steel wire ropes). For a support with a given tonnage, the diameter phi of the steel wire rope depends on the number n of the steel wire ropes, n affects the size of the support, and the larger n is the larger the size of the support, the higher the cost of the support is, so that the diameter of the steel wire rope is selected in proportion to the tonnage of the support from the economical aspect.
For a large-tonnage support, the diameter phi of the inhaul cable is larger, the flexibility of the steel wire rope is poor, the bending rigidity of the steel wire rope is larger, the restoring force of the elastic element is insufficient, and the self-resetting effect is poor.
The larger diameter of the steel wire rope leads to larger minimum bending radius, inevitably leads to larger wave shape and larger rope groove, leads to larger size of the support and poor economical efficiency;
the supports with different tonnages adopt steel wire ropes with different diameters, so that elastic elements with different types and different wave-shaped rope grooves are required to be designed, and standardized production and manufacturing are difficult;
the bearing inhaul cable is used as a self-resetting inhaul cable at the same time, the same specification of steel wire ropes are adopted, the economy is poor, and after one of the two functions is damaged, the other function is affected.

(3) The damping limiting cable component for bearing and damping functions and the self-resetting cable component for self-resetting of the support body are separately arranged, the two components are not affected by each other, the respective functions are realized, and the service life of the damping support can be prolonged.
(4) Because the design bearing capacity of the self-resetting cable assembly only needs to overcome the friction force of the support body, the design bearing capacity of the self-resetting cable assembly is small, the self-resetting cable assembly with good flexibility and small diameter can be selected for use, standardized manufacturing is convenient, and the support resetting requirements of different tonnages can be met only by reasonably increasing and decreasing the number of the self-resetting cable assemblies.
(5) The self-resetting support is simple in structural form, and can be used for selecting the self-resetting inhaul cable components and the damping and limiting inhaul cable components with different flexibilities and diameters while the resetting and limiting functions are added, so that the excessive increase of the size of the support body is avoided, and the economy is good.
(6) The damping support is simple in structure and convenient to manufacture and install.
The damping limiting inhaul cable assembly comprises a plurality of damping inhaul cables 7, the end parts of the damping inhaul cables 7 are fixed in the rope groove I4 through the inhaul cable anchoring assembly, and the rest parts of the damping inhaul cables 7 are in sliding connection with the rope groove I4;
further, the upper seat board 2, the lower seat board 3 and the damping stay rope 7 which is arranged in the rope groove I4 and used for bearing and limiting are connected into a whole, and reasonable earthquake displacement is reserved between the upper seat board 2 and the lower seat board 3 by the damping stay rope 7; during an earthquake, the upper seat plate 2 and the lower seat plate 3 can relatively displace, and the damping inhaul cable 7 has elasticity, can realize a damping function and can effectively prevent beam falling disasters from happening.
It should be noted that the diameter of the rope groove one 4 is determined according to the diameter of the shock absorbing rope 7 and the number of shock absorbing ropes 7 (the number is generally 1 or 2) accommodated in each rope groove one 4, and the size of the rope groove one 4 should be slightly larger than the diameter of the shock absorbing rope 7 multiplied by the number of the shock absorbing ropes 7 so as to ensure that the shock absorbing rope 7 can freely slide in the rope groove one 4 along the axial direction thereof.
The self-resetting inhaul cable assembly comprises a self-resetting inhaul cable 8 and an elastic element, the end part of the self-resetting inhaul cable 8 is fixed in the second rope groove 5 through the inhaul cable anchoring assembly, the rest part of the self-resetting inhaul cable 8 is in sliding connection with the second rope groove 5, at least one elastic element is arranged, the elastic element and the self-resetting inhaul cable 8 are integrally arranged, and the diameter of the self-resetting inhaul cable 8 is smaller than that of the shock absorption inhaul cable 7;
the working principle of the self-resetting inhaul cable component is as follows:
in the initial state, the part of the self-resetting inhaul cable 8, which is installed together with the elastic element, is in a bending state; when an earthquake happens, the upper seat board 2 and the lower seat board 3 can relatively displace, the upper seat board 2 and the lower seat board 3 can pull the self-resetting inhaul cable 8 and the elastic element, the elastic element is promoted to be stretched, the bending section of the self-resetting inhaul cable 8 can also stretch along with the elastic element, and the elastic element has elastic potential energy at the moment; after the earthquake, the support body may have residual displacement, and the self-resetting function of the support is realized by restoring the stretched bending section of the self-resetting inhaul cable 8 to the original state by means of the high elasticity of the elastic element and re-tightening the bending section in the rope groove II 5, thereby eliminating the residual displacement of the support.
Because the bearing capacity of the self-resetting cable assembly is designed only by overcoming the friction force of the support body, when the self-resetting cable 8 in the self-resetting cable assembly is designed, the self-resetting cable 8 with smaller bearing capacity can be selected, for example, the self-resetting cable 8 with good flexibility and small diameter is selected, so that standardized production is convenient, and the support resetting requirements of different tonnages can be met by reasonably increasing and decreasing the number of the self-resetting cable assemblies.
In particular, the first rope groove 4 is generally rectangular in shape, and the second rope groove 5 may be rectangular or circular depending on the shape of the elastic element 10 after wrapping around the curved section of the self-resetting cable 8.
The elastic element comprises a high-elasticity rubber element 12, a curve hole 13 is formed in the high-elasticity rubber element 12, and the self-resetting inhaul cable 8 passes through the curve hole 13 and is fixed with the high-elasticity rubber element 12 into a whole;
in this embodiment, as shown in fig. 2, 3 and 5, the high elastic rubber element 12 and the bending section of the self-resetting cable 8 are combined into an integral structure, no relative displacement is generated between the two, when the support body is displaced, the bending section of the self-resetting cable 8 is gradually pulled into a straight line shape, and the elastic element wrapping the bending section of the self-resetting cable 8 is also simultaneously stretched and deformed, and the two are cooperatively deformed, so that the seismic displacement requirement of the support body is met.
In another embodiment, as shown in fig. 13, the self-resetting cable 8 is woven into a ring shape, the two rope grooves 5 in the upper seat plate 2 and the lower seat plate 3 are respectively provided with a high-elasticity rubber element 12, the two high-elasticity rubber elements 12 wrap the self-resetting cable 8, and the wrapped parts of the self-resetting cable 8 are respectively provided with a bending section, so that the design is suitable for the condition of larger earthquake displacement.
Guide sliding blocks 14 are arranged on two sides of the inner wall of the rope groove II 5 and close to the outer edge, and the guide sliding blocks 14 are in sliding connection with the self-resetting inhaul cable 8;
further, as shown in fig. 3, the guide slider 14 is provided for the purpose of limiting the displacement of the high elastic rubber member 12, ensuring that it is always located in the second rope groove 5, and ensuring that the self-resetting cable 8 can protrude from the center of the second rope groove 5.
It should be noted that, the displacement of the bending section of the self-resetting cable 8 in the curve hole 13 is greater than the limit displacement of the shock-absorbing limit cable component, the deformation of the high elastic rubber element 12 is greater than or equal to the limit displacement required by the earthquake of the support body, and the load value of the high elastic rubber element 12 is greater than or equal to the self-resetting friction force of the support, so that the shock-absorbing limit cable component bears the earthquake acting force when the earthquake occurs, the self-resetting cable component does not bear the earthquake acting force, and the self-resetting cable component can be prevented from being damaged when the earthquake occurs.
The elastic element comprises a plurality of belleville springs 9, the belleville springs 9 are fixed into a whole to form a belleville spring assembly, and the self-resetting inhaul cable 8 passes through the belleville spring assembly and is detachably connected with the belleville spring assembly;
in this embodiment, as shown in fig. 7, 9 and 11, the connection mode of the self-resetting cable 8 and the belleville spring assembly may be a buckle connection or a chain connection, or may be other detachable connection modes, when the support body is displaced normally or the displacement is caused by an earthquake, the belleville spring assembly is compressed gradually, and the compression deformation amount generated by the belleville spring assembly is just the displacement required by the support body provided by the self-resetting cable 8; after the earthquake, the belleville spring component gradually restores to the original state, and simultaneously the self-resetting inhaul cable 8 is tightened, so that the residual displacement of the support body is eliminated, and the self-resetting function of the support body is realized.
In another embodiment, as shown in fig. 8, two belleville spring assemblies are respectively arranged in the rope grooves 2 and 5 in the upper seat plate 2 and the lower seat plate 3, and the two belleville spring assemblies wrap the self-resetting inhaul cable 8, the wrapped part of the self-resetting inhaul cable 8 is in a loose state, and the design is suitable for the condition of larger earthquake displacement.
Preferably, if the diameter of the self-resetting cable 8 is smaller than the diameter of the damping limit cable 7 in design, the deformation of the belleville spring assembly is slightly larger than the limit displacement of the damping limit cable assembly, so that the damping limit cable assembly bears the earthquake acting force when an earthquake occurs, and the self-resetting cable assembly does not bear the earthquake acting force, thereby preventing the self-resetting cable assembly from being damaged in the earthquake.
