With the improvement of the living standard of modern people, more and more buildings need to be provided with machine room free elevators to meet the needs of daily life. The popularization of the elevator without the machine room has the increasing importance of reducing the installation cost and the later maintenance cost under the condition of ensuring the operation safety of the elevator without the machine room.

When the existing elevator without the machine room is installed, main machine equipment is completely installed in a hoistway, and the arrangement is very compact. In view of the arrangement characteristics of the rope head fixing mode of the machine room free elevator, the rope head unit is generally arranged on the other side of the support beam corresponding to the traction main machine area and is positioned above the support beam, and a large part of space is occupied in all directions, so that the use waste of the support beam is caused.

Accordingly, there is a need for an installation structure that can make full use of the space of the support beam, and is advantageous for reducing the height of the top floor of the hoistway and improving the utilization rate of the hoistway.

As shown in fig. 1 and 2, in an embodiment, the mounting structure includes a support beam 100, a traction main machine 200, a rope head unit 300, and a counterweight sheave 400, the support beam 100 includes a first side surface 110, a second side surface 120 disposed opposite to the first side surface 110, and a support body 130 disposed between the first side surface 110 and the second side surface 120, the traction main machine 200 is fixedly disposed on the support body 130, the traction main machine 200 includes a rotatable traction sheave 210, the rope head unit 300 is disposed on the support body 130, and the rope head unit 300 and the traction sheave 210 are disposed at intervals in a direction from the first side surface 110 to the second side surface 120; a counterweight sheave 400 rotatably supported on the support beam 100, the counterweight sheave 400 being disposed obliquely between the rope head unit 300 and the traction sheave 210; wherein the rope outlet end of the rope head unit 300 is engaged with the rope inlet end of the counterweight sheave 400, and the rope outlet end of the counterweight sheave 400 is engaged with the rope inlet end of the traction sheave 210.
