Specific embodiment

Embodiment: a kind of shock-absorbing supporting device for fire-fighting, including anti-buckling support and damper, the anti-buckling branch It supports, the surface of damper has fire resistant coating.

The anti-buckling support, including energy consumption inner core 1-1, baffle 1-4, connecting plate 1-6 and constraint outer sleeve, constrain housing 7 cover of cylinder is connected to the periphery of energy consumption inner core 1-1, and extends outward constraint housing along the both ends of energy consumption inner core 1-1 axis direction Cylinder 1-7, and be connected on connecting plate 1-6 by baffle 4, constraint outer sleeve 1-7 has one group of opposite and parallel horizontal interior wall 1- 10, energy consumption inner core 1-1 is in parallel, and energy consumption inner core 1-1 connects one end inside constraint outer sleeve 1-7 along its axis direction quilt cover The anti-unstability device of the first torsion of installation in space between the inner wall of portion constraint outer sleeve 1-7 corresponding with the end；And it is described Installation second is turned round in space between the inner wall of the other end of energy consumption inner core 1-1 constraint outer sleeve 1-7 corresponding with the end Turn anti-unstability device.The energy consumption inner core of the part, tool is there are two side, the inner wall of the corresponding constraint outer sleeve in each side, i.e., (the first anti-mistake of torsion of anti-unstability device is reversed in installation between two sides of horizontal interior wall, two horizontal interior walls and energy consumption inner core Stabilization device, the second anti-unstability device of torsion).The end refers at the 3cm-10cm that energy consumption inner core end is risen, certainly can be with It is smaller or larger.In practice, it has been found that be more proximate to the initial position of load transmission, and correspond to the knot of position in fact Beam position, i.e. space near two terminals of energy consumption inner core form twisted planar using torsionspring, need to energy consumption inner core Correction demand is stronger, also, grasps two positions, can start to correct in source, not make displacement transfer as far as possible, thus The section that deformation can be further decreased inhibits the ability of deformation stronger, thus the present embodiment selects the anti-unstability dress of two torsions It sets, is separately mounted to two ends of energy consumption inner core.

In this embodiment, the anti-unstability device of first torsion includes torsionspring 1-2, limiting card 1-4 and guiding iron Through energy consumption inner core 1-1, (by upper, this is passed through on the axis direction perpendicular to energy consumption inner core 1-1 by stick 1-3, the guiding iron staff 1-3 Perforation is located at one end described in energy consumption inner core), and be fixed on energy consumption inner core 1-1, iron core is exposed in the space Two sides are covered by torsionspring 1-2 to be connect thereon, and the spring arm of force of connection 2 ontology of torsionspring is limited card 1-4 limit respectively and is turning round Turn the upper and lower two sides of the twisted planar formed when spring 1-2 torsion.In this embodiment, the first anti-unstability device side of torsion The end of energy consumption inner core be directly connected in baffle, and connecting plate is connected by baffle.

In this embodiment, the energy consumption inner core 1-1 is the cuboid of strip, is plugged on the pact that shape is long cylinder rectangle The position in the essentially center inside beam outer sleeve 1-7, the iron staff is through energy consumption inner core 1-1 and symmetrical, the torsion in two sides The restraining position for turning spring 1-2 installation site and its spring arm of force is symmetrical centered on by perforative energy consumption inner core 1-1.Center It is symmetrical arranged, so that the reaction force of two twisted planars is more consistent, distortion correction and twisted planar energy consumption is imitated Fruit is more preferably.Further, in general, energy consumption inner core is understood some and is in outside constraint outer sleeve, should be partially due to straight Exposed unfettered and support is connect, the energy consumption inner core compared inside constraint outer sleeve is more weak, easily destroys.It uses Steel plate, rack gear, is combined with the limit of volute spring gear, the exposed part in constraint outer sleeve, using in steel plate substitution energy consumption Core, and the mode being bolted to connection will have the steel plate and Interal fixation of rack gear, to rack gear be fixed, although should Part is not covered by energy consumption inner core, but also enhances the intensity of the exposed part to a certain extent；Volute spring to consume The displacement of the lines of energy inner core is changed into angular displacement, also, it is in end nearby (being close to exposed sheet steel sections), so that Volute spring, meshed gears and the rack gear of limit and support frame can form frame in the exposed steel plate, have certain Supporting role, and the twisting resistance by volute spring greatly reduce the exposed part and act in load on the basis of support Under movement (rock and swing), so as to shorten the range of join domain, the program realizes the purpose for preventing unstability.

In this embodiment, the second anti-unstability device of torsion includes steel plate, the steel plate 1-9 with rack gear, gear 1-12, whirlpool Spring 1-13 and support frame are revolved, in the embodiment, the energy consumption inner core 1-1 and baffle 1- of the second anti-unstability device side of torsion 5 are not directly coupled, energy consumption inner core 1-1 junction steel plate 1-8, steel plate 1-8 connection baffle 5, baffle 1-5 connection connecting plate 1-6.I.e. Described the other end of steel plate 1-8 connection energy consumption inner core 1-1, two steel plate 1-8 with rack gear are respectively symmetrically fixed on institute State steel plate 1-8 two sides (side parallel surface i.e. parallel with horizontal interior wall, preferably, the steel plate and Steel plate with rack gear has bolt hole, is fastenedly connected steel plate and steel plate with rack gear by bolt), respectively have the steel of rack gear Be equipped between the inner wall of the constraint outer sleeve 1-7 of plate 1-9 corresponding thereto and in parallel with rack gear 1-11 meshed gears 1-12, and The upper and lower two sides of the gear 1-12 are directly fixed, and there are two the volute spring 1-13 being limited on the horizontal interior wall, should Gear and volute spring by the support frame by being stretched out on the horizontal interior wall be fixed on the steel plate with rack gear corresponding thereto and Between the inner wall of parallel constraint outer sleeve, the support frame is fixed on the crossbearer 1-14 of the horizontal interior wall including two, Its top for being located at two volute spring 1-13 and one is through the perpendicular of crossbearer 1-14, volute spring 1-13 and gear 1-12 Axis 1-15, the volute spring 1-13 are limited on the horizontal interior wall by limit card slot 1-16.Above scheme is as a result, to consume energy Inner core is center line, and gear, volute spring, the rack gear of two sides are respectively symmetrical installation, central symmetry setting, so that two whirlpools The reaction force for revolving plane is more consistent, for distortion correction and the equal better effect of vortex plane energy consumption.In this embodiment In, nearby space all has the possibility for installing gear spring to entire energy consumption inner core, however, in practice, it has been found that lean on The initial position of nearly load transmission, and correspond to the end position of initial position, i.e. space near two terminals of energy consumption inner core, Twisted planar is formed using volute spring, needs the correction demand to energy consumption inner core stronger, also, grasp two positions, It can start to correct in source, not make displacement transfer as far as possible, so as to further decrease the section of deformation, inhibit deformation Ability is stronger, thus we select using junction steel plate as inner core both ends, and the mode shape of rack gear is installed on junction steel plate At above scheme.Further, in general, energy consumption inner core understand some be in constraint outer sleeve outside, the part by In directly it is exposed, compare in constraint outer sleeve inside energy consumption inner core, due to it is unfettered and support, more weak, Yi Fa It is raw to destroy.Using anti-unstability device is reversed, guiding iron staff therein is combined with the limit of torsionspring, so that the line of energy consumption inner core Displacive transformation is angular displacement, also, reverses anti-unstability device and be in end nearby (being close to exposed energy consumption inner core part), from And guiding iron staff is allowed to form frame in the exposed energy consumption inner core part, there is certain supporting role, and by The twisting resistance of torsionspring greatly reduces movement of the exposed part under load effect and (rocks and put on the basis of support It is dynamic), so as to shorten the range of join domain, the program realizes the purpose for preventing unstability.

In this embodiment, the torsionspring and/or volute spring of marmem by being made.The torsion Turning spring is by helical spring and to be connected to the arm of force at helical spring both ends and form, volute spring be by volute spring ontology and It is connected to the arm of force composition at volute spring both ends, the super elastic characteristics of marmem are compared with other ordinary metallic materials Have many advantages: the fatigue properties of super elastic shape memory alloy first are fine, and inevitably go out in other materials circulation It now damages, influences the service life；Secondly marmem recoverable strain value is very big, this is that ordinary metallic material is difficult to realize； Finally, due to which austenite phase elasticity modulus is greater than martensitic phase elasticity modulus, shape memory alloy elastic modulus is increased with temperature And increasing (opposite with common metal), this makes it that can still keep higher elasticity modulus at relatively high temperatures.Therefore, shape is utilized Memorial alloy can be fabricated to the spring section of the device.

The anti-buckling support as described in the examples, under geological process, energy consumption inner core is come by from building transmitting Load, energy consumption inner core is deformed:

In one embodiment, in the first anti-unstability device side of torsion:

Energy consumption inner core drives torsionspring deformation by the guiding iron staff being fixed thereon, and torsionspring planar generates torsion Square, torsionspring are limited in the upper and lower two sides of the twisted planar formed when torsionspring torsion, and the torsion of torsionspring drives Energy consumption inner core generates the movement opposite with deformation direction, makes shape and position reply of the energy consumption inner core to nature when.As a result, Having the anti-buckling support of double anti-unstability devices of torsion in each example has to mitigate the effect shaken to structure for tradition The anti-buckling support of double anti-unstability devices of torsion, carries out unstability to end and reinforces design, slows down the impaired of inner core.In earthquake conditions Under, improve the ability to work of support.It is made into torsionspring using marmem, device is with double anti-unstabilitys of torsion Anti-buckling support energy consumption inner core, torsionspring, the outer sleeve upper limit card of device work together, and make it have certain Self-resetting function Can, slow down the impaired of inner core.Torsionspring belongs to helical spring, and the end of torsionspring is fixed to other assemblies, when other When component is rotated around spring center, which retracts initial position for them, generates torque or rotary force.Torsionspring can be with Storage is with separation angle energy or by fixing a certain device around the spring body middle shaft rotation arm of force with static state.Limiting card can limit torsion Turn spring position, fixed spring can be played the role of, while limitation binding material, inner core can also be played.The device It is simple to operation to be connected by way of assembling, convenient disassembly and facilitate shake after reparation and daily dimension Shield.Under geological process, energy consumption inner core will receive the load come from building transmitting, and inner core can be deformed, and inner core drives Torsionspring deformation, planar generates torque, torsion with higher.Due to the presence of inner core limit card slot, the torsion of generation Power will drive inner core movement, so that it is returned to original position, therefore device has runback bit function.Structure is by geological process When, no matter end is in compression or tension state, can realize Self-resetting by the restoring force of torsionspring, reduce The compressive deformation of inner core improves energy dissipation capacity and also ensures monolithic stability after inner core surrender, do not influence to support normal work Make.

In one embodiment, in the second anti-unstability device side of torsion:

Under geological process, energy consumption inner core is deformed, and in certain load range, energy consumption inner core deformation causes its two sides Gear is engaged with the rack gear on steel plate, and deformation moves gear band carry-over bar to energy consumption inner core deformation opposite direction, so that with Shape and position when the energy consumption inner core of gear connection is to nature are replied；(the reply of gear when being more than the load range Power can not reply energy consumption inner core), the volute spring for being fixed on the upper and lower two sides of gear is caused to deform by the deformation of energy consumption inner core And torque is planar generated, volute spring is limited on horizontal interior wall, and the restoring force that volute spring generates drives gear Rack gear is moved to energy consumption inner core deformation opposite direction so that shape when the energy consumption inner core connecting with gear is to nature and It replys position.Disclosure main purpose is to mitigate vibration to structure function, for setting for traditional anti-buckling support as a result, Meter, provides a kind of device of Self-resetting, slows down the impaired of inner core.Under geological process, enabling capabilities are improved.It is made into vortex Spring is added on gear, and anti-buckling support energy consumption inner core, gear, vortex bullet with double anti-unstability devices of torsion are made Spring, outer sleeve upper limit card work together, and the displacement of the lines integrally generated is converted into angular displacement, and it is with certain Self-resetting Function slows down the impaired of inner core.Gear solves that spring corner is too small is not able to satisfy inner core route problem.

Material torque, generation elasticity of flexure deformation by bending after volute spring deformation, thus spring is generated in own layer Torsion.The size and torque of its deformation angle are directly proportional, have high torsion, the torsional moment of multi-angle is applied to long-time work done Mechanism, have tireless characteristic.The disclosure is simple to operation can be connected by way of assembling, convenient disassembly And facilitate the reparation and daily maintenance after shake.

In the present embodiment, spring is connect with gear by riveting method, guarantees that spring can be rotated together with gear.

Implementation method: under geological process, inner core meeting bearing load is deformed, and inner core will drive volute spring deformation, Planar generate torque, torsion with higher.Due to the presence of inner core limit card slot, the torsion of generation will drive inner core fortune It is dynamic, so that it is returned to original position, therefore device has runback bit function.

When structure is by geological process, no matter end makes in compression or tension can be by the reply of volute spring Power realizes Self-resetting, reduces the compressive deformation of inner core, improves energy dissipation capacity and also ensures monolithic stability after inner core surrender, Improve the anti-seismic performance and survival ability of structure.

The application method of the grading damper is as follows:

Two steel plates of first steel plate group 2-1 are slided along the inner wall of the second steel plate group 2-2, until chock 2-3 and the first steel plate group The end of 2-1, which is contacted, is moved to the chock 2-3 connecting with spring in accommodating hole with compressed spring, and chock 2-3 is with the first steel plate Until by popping up in the chock fixation hole 2-6 of the second steel plate group 2-2, the first steel plate group 2-1 is fixed no longer sliding for group 2-1 sliding Dynamic, the fixing axle 2-14 is slided with the first steel plate group 2-1 on the first steel plate group 2-1, and in sliding process, is connected to it On L shape steel arm 2-11 gradually deform, and another L shape steel arm 11 connected to it is caused gradually to deform, the L shape steel arm 2-11 is deformed to drive lifting arm 2-12 to be lifted up, and lifting arm 2-12 drives steel column 2-13 connected to it to be lifted up, and is made Divided spring connection；

Lifting arm 2-12 is parallel to the side of outer sleeve 2-8 and inner cylinder 2-9, and steel column 2-13 is vertical grafting, lifting arm 2- 12 when being lifted up, and steel column 2-13 is driven to be detached from the limit hole on inner cylinder 2-9, and in being limited in by the limit hole of outer sleeve 2-8 Between cylinder 2-9 and outer sleeve 2-8.

Chock 2-3 is squeezed, makes it by bouncing back in chock fixation hole 2-6, by the first steel plate group 2-1 along the second steel plate group 2-2 Inner wall is pulled outwardly cunning, and the fixing axle 2-14 on the first steel plate group 2-1 slides in and out with the first steel plate group 2-1, and in sliding process In, the L shape steel arm 2-11 being connected thereto gradually is deformed, and another L shape steel arm 2-11 connected to it is caused gradually to become Shape, to drive lifting arm 2-12 falls downward, lifting arm 2-12 drives steel column 2- connected to it for L shape steel arm 2-11 deformation 13 falls downwards, until steel column 2-13 is demarcated the spring 2-10 made of memorial alloy the recess of spring 2-10.
