[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 A home elevator with a rear counterweight shown includes a traction machine fixing frame 1 for installing the traction machine, a top beam assembly 2 and a rope head beam assembly 3, which are fixedly connected to each other to form a whole.

[0023] The traction machine fixing frame 1 is installed on the left and right counterweight guide rails through the traction lateral fixing frames 4 welded and fixed on both sides, and the top beam assembly 2 is installed on the left and right car guide rails through the top beam lateral fixing frames 5 welded and fixed on both sides. The top beam assembly 2 is located at the front side and is arranged parallel to the traction machine fixing frame 1, and the rope head beam assembly 3 is vertically fixed to the upper part of the top beam assembly 2. The rear end of the rope head beam assembly 3 is bolted to the upper end of the rope pulley frame, and the lower end of the rope pulley frame is bolted to the middle of the traction machine fixing frame 1. The height of the traction machine is flush with the height of the rope head beam assembly 3.

[0024] A rope pressing wheel 61 matching with the traction wheel is installed on the rope pressing wheel frame. A first guide wheel 62 and a second guide wheel 63 are installed on the rope head beam assembly 3. The traction wheel, the rope pressing wheel 61, the first guide wheel 62 and the second guide wheel 63 are arranged in sequence from back to front and their axis centers are parallel. The axis center line of the rope pressing wheel 61 is lower than the axis center line of the traction wheel, and the axis center lines of the first guide wheel 62 and the second guide wheel 63 are parallel and higher than the axis center line of the traction wheel. The centers of the traction wheel, the rope pressing wheel 61, the first guide wheel 62 and the second guide wheel 63 of the traction machine are all located on the car guide rails on both sides and the center plane of the car guide rails on both sides.

[0025] The top beam assembly 2 includes two top beams which are fixedly arranged horizontally in front of and behind each other and extend in left-right directions. An escape space is formed between the two top beams for the upper beam assembly of the lower car to be lifted up and down.
