Shallow bottom pit steel belt traction home lift

Abstract

The invention discloses a shallow bottom pit steel belt traction home lift. The shallow bottom pit steel belt traction home lift comprises a steel frame, and a lift car and a counterweight device arearranged in the steel frame; a first bracket and a second bracket are arranged at the top end of the steel frame, a traction machine, a first rope hitch and an anti-bouncer are arranged on the first bracket, and a second rope hitch is arranged on the second bracket; a steel belt is arranged on the first rope hitch and comprises two rows of steel wire rope groups which are arranged in a spaced mode, an elastic rubber layer and a polyurethane layer are sequentially arranged outside each steel wire rope group, and the outer side face of each polyurethane layer is provided with skidproof stripes;and one end of the steel belt is fixedly connected with the first rope hitch, and the other end of the steel belt sequentially winds around a counterweight wheel of the counterweight device, tractionwheels of the traction machine, the anti-bouncer and car bottom wheels arranged at the bottom of the lift car and then is fixedly connected with the second rope hitch. The shallow bottom pit steel belt traction home lift has the characteristics that the later-period maintenance cost is low, a shaft can not be contaminated, a traction rope is high in strength, good in durability and long in servicelife, and the lift riding comfortability is good.

Description

technical field [0001] The invention relates to a traction household elevator, in particular to a shallow pit steel belt traction household elevator. Background technique [0002] At present, home elevators mainly use steel wire ropes as traction ropes, and rely on the friction of steel wire ropes to drive the movement of the entire car. However, since the steel wire ropes need to be added with lubricating oil, maintenance is inconvenient, which increases the labor cost of later maintenance, and the lubricating oil still needs to be added during the process. It will cause oil pollution in the hoistway; and the general steel wire rope is not high enough, and the bearing capacity needs to be strengthened; the outer surface of the steel wire rope is completely exposed to the outside, directly rubbing against the traction wheel and the counterweight wheel, which not only causes the traction wheel and the counterweight wheel Serious wear and tear will shorten the service life, an...

[0002] At present, home elevators mainly use steel wire ropes as traction ropes, and rely on the friction of steel wire ropes to drive the movement of the entire car. However, since the steel wire ropes need to be added with lubricating oil, maintenance is inconvenient, which increases the labor cost of later maintenance, and the lubricating oil still needs to be added during the process. It will cause oil pollution in the hoistway; and the general steel wire rope is not high enough, and the bearing capacity needs to be strengthened; the outer surface of the steel wire rope is completely exposed to the outside, directly rubbing against the traction wheel and the counterweight wheel, which not only causes the traction wheel and the counterweight wheel Serious wear and tear will shorten the service life, and affect the stability of elevator lifting, increase the noise of the elevator, and the comfort of the elevator is not good enough. It is also easily eroded by air, water vapor and other substances, resulting in rust and broken bones. Poor and short service life; therefore, the existing home elevators have the problems of high later maintenance cost, pollution of the shaft, insufficient strength of the traction rope, poor durability, short service life, and the need to improve the comfort of the elevator
