Cargo elevator car with dual vibration-damping function

Abstract

The invention relates to the technical field of elevator control, and discloses a cargo elevator car with a dual vibration-damping function. Vibration-damping supporting legs are arranged on the lowerend surface of the outer side of the car, wherein the vibration-damping supporting legs are arranged at four corners of the outer side of a car body, the two side faces of each vibration-damping supporting leg are in sliding connection with the side face of the car body, and the upper end of the bottom face of each vibration-damping supporting leg is connected with the lower end face of the car body through a vibration-damping spring; a first buffer layer is arranged on the lower end face of the car body, and the four vibration-damping supporting legs are further connected with a second buffer layer; and an air inlet fan is arranged on the upper end face of the car body, an air outlet of the air inlet fan communicates with the interior of the car body, a supporting plate is connected to the inner upper end of the car body, and an annular poisonous gas filtering layer and an annular particle adsorption layer are sequentially arranged on the outer edge of the upper end face of the supporting plate from inside to outside. The cargo elevator car has the beneficial effects that the triggering condition of a vibration-damping device is low, the vibration-damping effect is obvious, the use experience effect is good, and the fire prevention and life saving functions are achieved.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to a cargo elevator car with double damping functions. Background technique [0002] When the elevator is running at high speed, due to the different expansion and contraction degrees of the wire rope and the rope end, the car will vibrate or resonate by itself. At present, in order to eliminate the vibration effect of the elevator, some elevator cars are equipped with multi-layer vibration isolation layers or Double-hulled cars are installed, and others are provided with vibration-damping cushions at the bottom of the car. The trigger of the vibration-damping device in the above method is not sensitive enough, and it is easy to fail, and the effect of vibration reduction is not obvious enough, and the user experience effect is poor. In addition, the elevator As a commonly used means of transportation in buildings, in case of fire, power outage and other sudden accidents, t...

Problems solved by technology

[0003] In order to solve the deficiencies in the prior art that the triggering of the vibration damping device is not sensitive enough or difficult to trigger, the effect of vibration damping is not obvious enough, the effect of using experience is poor, the function of the elevator is not perfect enough, and it cannot be used as a fire-proof and life-saving elevator. Freight elevator car with low trigger condition of vibration damping device, obvious vibration damping effect, good user experience effect, double vibration damping function with fire and lifesaving functions
