Abstract
The utility model relates to an anti-shock elevator. Both sides of a guide way of the elevator are fixed with constrained damping layers by adhesive and bolts, and each constrained damping layer is formed by using adhesive to reciprocally agglutinate a viscous and elastic damping material and a steel clamping plate. When earthquake occurs, the constrained damping layers can consume huge amount of energy to largely reduce the deformation of the guide way, the separated displacement between the guide way and a guide boot and the vibration of a counterbalance weight. Therefore, the action of preventing the derailment of the counterbalance weight is achieved, and the elevator can evacuate personnel in time and increase the retreating rapidity of valuable goods in buildings after earthquake. The damage created by earthquake hazard is decreased.
Description
The utility model belongs to a kind of elevator, but the elevator that particularly a kind of antidetonation is destroyed.
During earthquake, in skyscraper, the safety of elevator is extremely important, because can the personnel that it is directly connected in the building in time evacuate after shake, also determining simultaneously the speed of withdrawing of valuable instrument and equipment in the building, it is to alleviating or preventing that the loss that follow-up aftershock produces has very important effect.Yet in the design and manufacturing process of elevator, people also do not satisfy requirement far away to the consideration of its anti-seismic performance, thereby cause the destruction of elevator in earthquake quite serious at present.
A large amount of earthquake calamities investigation and analysis show, in the various destructive factors of elevator, counterbalanced weight this collapse mode that derails almost accounts for more than 50%.During earthquake, if the motion of counterbalanced weight left and right directions is excessive, will causes the distance between boots and the side rails to increase, so that break away from fully, this moment, derailing just will take place counterbalanced weight destroyed if the external disturbance influence is arranged.How to avoid the generation of this collapse mode, do not appear in the newspapers as yet both at home and abroad at present, that is to say and also do not find the method that can solve till begging the present.
The purpose of this utility model is exactly that a kind of restriction damping layer is installed on the guide rail of elevator, to improve the shock resistance of existing elevator balanced heavy system, it is not destroyed in earthquake.Its groundwork just be the restriction damping layer of installing on the cage guide can dissipate a part elevator balanced heavy system seismic energy, can increase the rigidity and the damping of guide rail, reduce the earthquake response of guide rail, this just can prevent the generation of counterbalanced weight derailing in the earthquake, to various earthquake input, the vibrational energy of balance weight system is reduced more than 60%, therefore it can prevent that effectively elevator device destroys in the earthquake, personnel in the skyscraper of shake back can be evacuated rapidly, valuable instrument and equipment and other article are in time withdrawn, bring great convenience for shaking the back disaster relief work, the loss that follow-up aftershock is produced reduces greatly.
Normally used elevator as shown in Figure 1, it mainly is made of balance weight system and cage 5, and balance weight system is by counterbalanced weight 1, guide rail 2, guide rail bracket 3 with lead boots 4 and formed.And feature of the present utility model just be in the guide rail both sides of elevator with adhesives and bolt restriction damping layer.
Accompanying drawing 2 is the cross section structure figure that damping layer is installed on the cage guide.
Accompanying drawing 3 is the restriction damping layer structural representation.
Below in conjunction with the description of drawings preferred embodiment of the utility model.
Restriction damping layer is to be bonded by visco-elastic material 6 and steel clamping plate 7 usefulness adhesivess.Visco-elastic material 6 available thickness are 2～5mm, and length is 1/5～1/6 of guide rail 2 spans, rubber-type that height is identical with guide rail 2 edge of a wing height or foamed plastic type or the processing of pressure-sensitive adhesive type material.Steel clamping plate 7 are about 1cm for thickness, and length adds that with high the diameter of two-fold bolt 8 is long with the length that highly is visco-elastic material 6.
With restriction damping layer with adhesives and up and down two ends be fixed on bolt 8 in one section interval of both sides span centre of guide rail 2.
In earthquake, along with the vibration of counterbalanced weight 1, lead boots 4 and compress guide rail 2 repeatedly, make it to produce distortion.Because the rigidity of steel clamping plate 7 is very big, its distortion is less than the distortion of guide rail 2, so the visco-elastic material 6 between guide rail 2 and steel clamping plate 7 produces very big shearing strain, thereby in vibration processes, dissipate huge energy, make distortion, the guide rail 2 of guide rail 2 and lead disengagement displacement between the boots 4 and the vibration of counterbalanced weight 1 reduces greatly, reach to prevent that counterbalanced weight 1 from the effect of derailing taking place.
The utility model simple structure, cheap, its engineering are used and are bound to produce potential important social and economic benefit.
