Detailed Description

As shown in fig. 1 and 2, a counterweight space compact type 4: the utility model is exemplified by a pass-through door elevator without machine room having a front door 6 and a rear door 7, which is a roping ratio elevator 1. The front, rear, etc. terms of the present utility model are referenced to the figure 1. The counterweight 1 is provided on the right side wall in the hoistway.

A counterweight beam 4 and a load-bearing beam 5 are fixed at the top of the hoistway, and the counterweight beam 4 and the load-bearing beam 5 are actually arranged vertically. For the purpose of illustrating the roping arrangement, the counterweight beam 4 and the load bearing beam 5 are placed in parallel in fig. 2.

As shown in fig. 2, a counterweight rope end 42 and a counterweight return sheave 41 are fixed to the counterweight cross member 4. The load-bearing beam 5 is fixed with a car rope head 51, two car rope return sheaves 52 arranged in parallel, a traction machine and a machine room guide wheel 54 in sequence along the left-right direction.

The elevator further includes a car 2 that can move up and down in the hoistway along the rails, a counterweight 1 that can move up and down in the hoistway along the rails, and a wire rope 3. As shown in fig. 1, a first car top wheel 21 and a second car top wheel 22 are arranged side by side on the top of the car 2, and a first counterweight wheel 11 and a second counterweight wheel 12 are arranged side by side in front of and behind the top of the counterweight 1.

As shown in fig. 2, after one end of the wire rope 3 is fixed to the car rope head 51, it sequentially passes downward around the first car top sheave 21, upward around the two car return sheaves 52, downward around the second car top sheave 22, upward around the traction sheave 53 of the traction machine and the machine room guide sheave 54 from left to right, passes downward around the first counterweight sheave 11 from front to back, passes upward around the counterweight return sheave 41 from front to back, passes downward around the second counterweight sheave 12 from back to front, and is fixed to the counterweight rope head 42.
