Machine room-less elevator

Abstract

An elevator without a machine room comprises two guide rail frames with counterweight guide rails, a main machine beam, and a tractor arranged on the main machine beam. The main machine beam is fixed between the tops of the two guide rail frames. A counterweight rope head frame used for being connected with one end of a steel wire rope is further fixed between the two guide rail frames. The counterweight rope head frame is located below the main machine beam. According to the elevator without a machine room, the main machine beam provided with the tractor is directly fixed on the two counterweight guide rail frames and is further stabilized with the assistance of the added counterweight rope head frame. The elevator without a machine room is simple in structure, ingenious in design and convenient to install, lowers the construction cost and installation cost, reduces the top storey height of an elevator shaft, and saves the shaft space.

Description

Technical field [0001] The utility model relates to an elevator without a machine room. Background technique [0002] The machine room-less elevator is aimed at the machine room elevator. The feature of machine roomless elevators is that there is no machine room, which reduces costs for builders, is energy-saving, environmentally friendly, and does not occupy space other than the hoistway. There are usually the following installation methods: (1) Top-mounted type: the permanent magnet synchronous traction machine is placed on the top of the hoistway, and the main beam is installed through the hole on the top wall of the hoistway; (2) Down-mounted type: the permanent magnet synchronous traction machine is installed Placed at the bottom of the hoistway; (3) Car top drive type: place the traction machine on the top of the car and move with the car; (4) Counterweight drive type: place the traction machine on the counterweight and move with it. These methods usually have the followi...

AI Technical Summary

Problems solved by technology

These methods usually have the following defects: the traction machine installation structure of this traditional machine room-less elevator has the following defects: it is necessary to open holes on the well wall in advance, and the construction cost is relatively high; it is necessary to erect crossbeams in the well, which is troublesome to install, and After the installation is completed, the post-processing of the civil work is required, and the installation is cumbersome; when installing the traction machine, the beam is raised away from the upper end of the guide rail bracket, counterweight guide rail and car guide rail, which takes up a lot of space, and the height of the top floor of the elevator shaft is difficult to increase. reduce
