Abstract
The utility model discloses a safety device for a pulling cable type glass curtain wall. The safety device comprises a safety lever, an oil cylinder shock absorber, an adjusting sleeve and a screw rod pressing pulling cable, wherein the oil cylinder shock absorber comprises a cylinder body, a piston, a piston rod, a compression spring, a one-way valve, a cylinder cover and a sealing rubber ring; a fixing support seat is connected with a main pulling cable through the safety lever; and the oil cylinder shock absorber is connected with the main pulling cable by using a cable fastener through the adjusting sleeve and the screw rod pressing pulling cable after being connected with another fixing support seat. The one-way valve and a damp throttling hole are designed on the piston of the safety device, so that the hydraulic damp throttling buffering shock absorption function is achieved, the stress of a pulling cable system can be effectively reduced when meeting impact loads such as extreme high wind and earthquake and the like, and strong reciprocating vibration caused by strong rebounding of the system is avoided at the same time so as to prevent the system from being crashed and protect the safety of the system. Therefore, the safety device can be widely applied to the field of safety protection of the pulling cable type glass curtain wall.
Description
Technical field
The utility model relates to a kind of curtain wall system safeties, relates in particular to a kind of drag-line curtain wall safeties.
Background technology
The drag-line curtain wall is glittering and translucent with it, brevity and lucidity, braced structures are very thin tasteful and refined and deeply be subjected to owner and architects' welcome, has obtained using more and more widely.But drag-line needs to apply larger pretightning force in use, also want the additional force of bearing glass deadweight, wind load, geological process, and the extra duty that produces will bear agent structure generation certain displacement the time, so that drag-line also just becomes a safe weak link of whole curtain wall system, particularly particularly remarkable because of acutely repeatedly vibrating its destruction of causing of the alternate load of extreme strong wind and violent earthquake.So, consider relevant safety locking motion is set, when drag-line is subject to the impact load of overburden, collapse with the collapse that prevents the curtain wall whole system, and then to avoid great casualties and property loss be beneficial.
Summary of the invention
The utility model is exactly a kind of drag-line curtain wall safeties that provide in order to overcome above-mentioned safety problem.
In order to achieve the above object, the technical scheme that the utility model adopts is: a kind of drag-line curtain wall safeties comprise bumper bar, oil cylinder damper, regulating sleeve, screw rod suppressed inhaul cable; Described oil cylinder damper is comprised of cylinder body, piston, piston rod, Compress Spring, one way valve, cylinder cap, O-ring seal.
The two ends of described bumper bar are shaped with the monaural joint; wherein an end is hinged by pin and fixed bearing; the other end is hinged by the compacting joint of pin and main drag-line; the maximal destruction pulling force of bumper bar adds the pretightning force minimum destruction pulling force that must be lower than with joint efforts main drag-line (comprising the joint junction) afterwards of preventer guy; to guarantee when meeting extreme imposed load; the bumper bar rupture failure of going ahead of the rest plays the effect of protection whole system safety.
The monaural joint of described oil cylinder damper is hinged by pin and fixed bearing, external screw thread and the regulating sleeve of its piston rod are affixed, the other end of regulating sleeve links to each other with the screw rod suppressed inhaul cable by screw thread again, the afterbody of screw rod suppressed inhaul cable has one section preventer guy, this preventer guy links to each other with main drag-line by the compacting claim-reduction, the direction and the described bumper bar that connect are in homonymy, are the almost parallel parallel connection.
The cylinder body afterbody of described oil cylinder damper is furnished with a monaural joint, is shaped with one section internal thread on the front inner wall of cylinder body; Described one way valve is installed on the piston, and with two end faces connections of piston, the liquid flow direction of one way valve flows to the piston inboard for the outside from piston; Also be furnished with a throttle orifice on the described piston with two end faces connections of piston; One end of described piston rod is fixedly connected with piston, and the other end is shaped with one section external screw thread; The outer rim of described cylinder cap is provided with one section external screw thread, and the through hole of cylinder cap central authorities is equipped with O-ring seal along being circumferentially with groove on the groove; First piston is pushed cylinder body together with piston rod during the assembling of oil cylinder damper, then servicing fluids force feed in the cylinder body, but do not fill it up with, in cylinder body, leave an air chamber, again Compress Spring is inserted on the piston rod, after the cylinder cap that will install at last O-ring seal passes piston rod, be fixed on the cylinder body by external screw thread.
The utlity model has hydraulic damping throttling buffering shock-absorbing function, its principle: during for normal operation, bumper bar provides a part of pulling force to main drag-line, and the Compress Spring of oil cylinder damper also is applied with certain prefastening force to the preventer guy of screw rod suppressed inhaul cable, this prefastening force also provides the pulling force of a part, the size that can conveniently regulate this prefastening force by regulating sleeve to main drag-line.When glass curtain wall system meets that the extreme external force such as violent typhoon or violent earthquake attacks by chance and when making the curtain wall system overburden, the bumper bar failure disconnects, the enormous impact load of main drag-line then passes on the piston of oil cylinder damper by preventer guy, and piston will be laterally, and (by piston rod side) is mobile.At this moment, because the extruding of piston, the hydraulic fluid pressure in the piston outside rises rapidly, after oil pressure surpassed certain value, one way valve was opened, and piston outside hydraulic oil flows into inboard fast by one way valve, piston is mobile laterally fast, spring is by Fast Compression, and spring force strengthens, and finally reaches equilibrium state.Because the rigidity of spring is less, system flexibility increases, and can effectively reduce the suffered impact force of system.After impact load disappears, spring promotes piston to the inside, at this moment, closed check valve, hydraulic oil can only be by the interior side inflow outside of throttle orifice from piston, because throttle orifice is less, has stronger damping action, flow is just slower, so piston can only be mobile to the inside lentamente, until reach new equalization point, the so violent reciprocating vibration of system with regard to having avoided causing because of strong resilience, just can prevent that also whole curtain wall system from because the collapse that produces of acutely repeatedly vibrating destroys, having improved the security performance grade, avoid causing the major disaster to the people and property.After the dangerous situation, reinstall rapidly bumper bar, and whole curtain wall system has been overhauled, eliminate other potential safety hazard, make system recover normal operation.
The effect of air chamber in the cylinder body: because piston is when moving back and forth, the size of dischargeable capacity also changes thereupon in the cylinder body, if filled hydraulic oil in the cylinder body, then can be because of the Incoercibility of hydraulic oil volume, and stop the motion of piston; Then can form the vacuum space such as counter motion, also can hinder the motion of piston.The existence of air chamber has then solved this problem.
