Description

A kind of bivalve dual shock absorption cargo lift carriage

Technical field

The utility model relates to elevator control technology field more particularly to a kind of bivalve dual shock absorption cargo lift carriages.

Background technique

When elevator is in high-speed cruising, because the telescopic level difference that wirerope and rope end combine, will lead to carriage appearance Itself vibration or resonance, currently in order to the vibrating effect of elevator is eliminated, it is some that a variety of vibration insulations are set on the elevator car, it is another A little then be that cushion layer is arranged in the bottom of carriage, the vibration absorber triggering of the above method is not sensitive enough, is easy failure, and subtracts The effect of vibration is not obvious enough, and usage experience effect is poor, in addition, elevator is as the vehicles common in building, encounter fire, When the burst accidents such as power failure, usually used lift car does not have the device of fire-proof self saving, and therefore, it is difficult to escape out of elevator Or seek survival for a long time, the function of elevator is incomplete.Such as: 205709318 U of Chinese patent authorization publication No. CN, authorization November 23 2016 day for announcing, invention and created name are a kind of double shock-absorbing type safety elevator, including carriage, buffer board and case Body, disadvantage is that the elevator is only provided with two layers of cushion block in the bottom end of carriage, vibration absorber triggering is not sensitive enough or difficult With triggering, the effect of vibration damping is not obvious enough, and usage experience effect is poor, and in addition the elevator functions are incomplete, can not be as anti- Fiery lifesaving elevator uses.

Utility model content

The utility model is not sensitive enough or be difficult to trigger, the effect of vibration damping in order to solve vibration absorber in the prior art triggering Fruit is not obvious enough, usage experience effect is poor, elevator functions are incomplete, can not as the deficiency that fire-proof lifesaving elevator uses, Provide that a kind of vibration absorber trigger condition is low, effect of vibration damping is obvious, usage experience effect is good, with fire-proof lifesaving function Bivalve dual shock absorption cargo lift carriage.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of bivalve dual shock absorption cargo lift carriage, including car body are additionally provided on the outside of the car body outer Skeleton, the outer skeleton include the vertical side plate of bottom plate and four sides, and the lateral wall of the side plate and car body is slidably connected, institute It states and is equipped with shock-absorbing spring at four ends angle of the upper surface of bottom plate, the upper surface of the bottom plate is additionally provided with second buffer layer, institute The lower end surface for stating car body is equipped with the first buffer layer that matches with second buffer layer, in the internal side wall of the car body Equipped with supply fan, the side wall of the car body is equipped with the open-work being connected with supply fan, the interior of the car body It is additionally provided with the toxic gas filter layer and granular absorption layer to connect with supply fan.The car body of the utility model is in outer skeleton Four ends angle at be provided with shock-absorbing spring, compared with double-layer vibration damping bed course in the prior art, greatly reduce vibration damping The weight and volume of device, vibration damping trigger condition is low, is more easier to trigger the vibration damping process of outer housing, and outer housing passes through four A end Angle Position carries out vibration damping simultaneously to carriage, and effectiveness in vibration suppression is more obvious, and vibration dispersion makes the passenger in carriage with adding uniformly It will not feel like oneself, and second buffer layer is set in the upper surface of bottom plate, the first buffering is accordingly set in the lower end of car body Layer, to constitute the second vibration absorber, when outer skeleton and car body close to each other, first buffer layer and second buffer layer phase Mutually close to and act on, play the effect of secondary vibration damping, further to carriage carry out vibration damping, effectiveness in vibration suppression is more preferably；Car body Inside be main fire-proof lifesaving position, in elevator unexpected accident can occur for the air inlet fan on carriage inner sidewall cannot When mobile, extraneous fresh air is input to the inside of carriage, it, also can be by muddy air when fire occurs for external environment Pass sequentially through toxic gas filter layer and granular absorption layer, by gas noxious material and cigarette ash dust-filtering fall, then convey To cab interior, allows passenger's breathing to pure air, extend the time waited for rescue, increase the probability of survival.

Preferably, the lateral wall of the car body is equipped with vertical sliding slot, the inner wall and sliding slot of the side plate are slided Connection, when the side plate slides into the bottom end of sliding slot, the upper surface of shock-absorbing spring is described not with the lower end face contact of car body When side plate slides into the top of sliding slot, the upper surface of shock-absorbing spring is close to the lower end surface of car body and shock-absorbing spring enters compression State.Car body and outer skeleton are slidably connected by sliding slot, limit the sliding distance of outer skeleton, when side plate slides into cunning When the bottom end of slot, the upper surface of shock-absorbing spring with the lower end face contact of car body, can not make shock-absorbing spring be in relaxation shape State makes its moment be prepared to enter into vibration damping working condition, and shock-absorbing spring is set to the bottom plate upper surface of outer skeleton, rather than will Its both ends is connected with outer skeleton and car body respectively, facilitates and disassembles outer skeleton, is conducive to maintenance and inspection, and works as side plate When sliding into the top of sliding slot, the upper surface of shock-absorbing spring and the lower end face contact of car body and shock-absorbing spring are in compression shape State, shock-absorbing spring is in vibration damping working condition at this time.

Preferably, being socketed rubber sleeve on the upper surface of the shock-absorbing spring.Rubber sleeve positioned at end can subtract The buffer function that certain effect is played when sharp impacts occurs for vibration spring, prevents shock-absorbing spring well damage, while also having one Determine the damping effect of effect.

Preferably, the first buffer layer and second buffer layer are PE foam.PE foam mobility is fabulous, to pressure Sensitivity, can slow down and absorb small vibration, and effectiveness in vibration suppression is good.

Preferably, the side wall of the car body successively includes fire resistant coating, insulating and inner panel from outside to inside Layer, the open-work are set to fire resistant coating and inner panel layer.Fire resistant coating prevents the shell of car body from burning, and insulating prevents External high temperature is transmitted toward the inside of car body, and the open-work on fire resistant coating and inner panel layer allows outside air to enter sedan-chair The inside of compartment ontology.

Therefore, a kind of bivalve dual shock absorption cargo lift carriage of the utility model has following advantages: vibration absorber touching Clockwork spring part is low, and the effect of vibration damping is obvious, and usage experience effect is good, has the function of fire-proof lifesaving.
