Vibration-proof single-wheel car roof diversion sheave capable of reliable connection

Abstract

The invention discloses a vibration-proof single-wheel car roof diversion sheave capable of reliable connection, which comprises a diversion sheave and a diversion sheave connecting part, wherein the diversion sheave is connected to the upper part of an upper cross beam through the diversion sheave connecting part. The vibration-proof single-wheel car roof diversion sheave is characterized in that the diversion sheave connecting part comprises a wheel body connecting part and a cross beam connecting part, and the wheel body connecting part and the cross beam connecting part are fixedly connected through a fixing device; the diversion sheave is in rotating shaft connection with the wheel body connecting part; and the cross beam connecting part comprises a connecting shaft and two connecting chuck plates, the cross beam connecting part is connected through the connecting shaft, the two connecting chuck plates are clamped on the upper and lower sides of the upper cross beam respectively, and the upper cross beam and the connecting chuck plate are provided with shock-absorbing cushion. The vibration-proof single-wheel car roof diversion sheave provided by the invention has strong reliability and improved safety performance, effectively prevents vibration and noise transmission, and distributes load evenly to multiple points.

Description

Technical field [0001] The invention relates to the field of elevator car manufacturing, in particular to an anti-vibration single-wheel type car top return sheave with reliable connection. Background technique [0002] The elevator is a vertical elevator powered by a motor, equipped with a box-shaped pod, used for multi-storey buildings to carry people or carry goods. The elevator has a car that runs between at least two rows of vertical guide rails. [0003] The return sheave is an indispensable part of the elevator. [0004] In the prior art, the car top return sheave and the upper beam are installed in parallel through the "U"-shaped hoop rigidity and are installed in parallel. They use more materials and are easy to transmit vibration and noise; they and the upper beam use a monolithic shock-absorbing pad. Not only is material wasted, but the force distribution cannot be performed well. In addition, each connection part is connected by welding, and the connection effect is unc...

Problems solved by technology

[0004] In the prior art, the car top rope return pulley and the upper beam are installed rigidly and in parallel through a "U"-shaped hoop, and use more materials, and at the same time, it is easy to transmit vibration and noise; Not only is material wasted, but at the same time, the force distribution cannot be well carried out. In addition, the connection parts are connected by welding, and the connection effect is uncontrollable and the reliability is poor.
