Reliable anti-vibration double-wheeled car top return sheave

Abstract

The invention discloses reliably connected shockproof dual wheel type car roof diversion sheaves. The reliably connected shockproof dual wheel type car roof diversion sheaves comprise diversion sheaves and a diversion sheave connection portion, wherein the diversion sheaves are connected above an upper beam through the diversion sheave connection portion. The reliable connected shockproof dual wheel type car roof diversion sheaves are characterized in that the two diversion sheaves are connected with two connection channel steel in a rotating shaft mode; the diversion sheave connection portion comprises a beam connection portion; the two connection channel steel are fixedly connected with the beam connection portion through a fixed device; the beam connection portion comprises a connection shaft and two connection blocking plates; the beam connection portion is connected with the upper beam through a connection shaft in a rotating shaft mode; the two connection blocking plates are arranged on the upper side and the lower side of the upper beam in a blocking mode; and the upper beam and the connection blocking plates are provided with shock pads. The reliably connected shockproof dual wheel type car roof diversion sheaves have the advantages of being good in reliability, improving the safety performance, effectively avoiding transmission of shocks and noises, enabling the load to be in uniform multipoint distribution, being stable in structure, preventing deformation and effectively preventing a hoisting rope from jumping out or falling off.

Description

technical field [0001] The invention relates to the field of elevator car manufacturing, in particular to an anti-vibration double-wheel car top rope return pulley with reliable connection. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. An elevator has a car that runs between at least two vertical guide rails. [0003] The return rope wheel is an indispensable part of the elevator. [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 the 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 ...

[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.
