Elevator device without machine room

Abstract

The invention relates to an elevator device without a machine room. The elevator device without the machine room comprises a lift well (102), a lift car (104), a counter-weight (106) close to the lift well wall of one side, a base (108) disposed at the lift well bottom (202), guide rails (110) for guiding the counter-weight, a traction machine (112) disposed on the lower portion of the lift well, a frame (114) of which one side is fixed to the guide rails and the lower portion is connected with the base through a pulling rod (208) and which is used for supporting the traction machine, a control cabinet (116) arranged in the lift well, reinforcing parts (210 and 410) which are connected with the other side of the frame and the base, a support (216) of which one end is fixed to the reinforcing parts and the other end is fixed to the guide rails and an operation platform (120) which is mounted on the support and used for maintaining the traction machine. The frame and the guide rails of the counter-weight are arranged side by side. Accordingly, supporting of the traction machine is reinforced, the operation platform support of which the mounting position is not limited by the lift well structure is provided, and the mounting freedom degree of the operation platform is increased.

Description

technical field [0001] The invention relates to a machine-roomless elevator device, in particular to a device for fixing a traction machine and a working platform in the elevator device. Background technique [0002] Figure 6 It is a perspective view briefly showing a traction system of a machine-room-less elevator device. The traction machine 112 is arranged at the bottom of the hoistway, and drives the car 104 and the counterweight 106 to move up and down through the traction rope 222 . For such an elevator device, how to stably fix the traction machine in a narrow shaft and how to set up a working platform for checking and repairing the traction machine are important issues. [0003] Japanese Patent Publication No. 2006-52076 discloses a fixing device for an elevator traction machine, which includes a mounting frame 11 supporting a traction machine 9 . The mounting frame 11 is composed of an upper frame 12, a lower frame 13, a side frame 14 and a side frame 15 in the s...

AI Technical Summary

Problems solved by technology

When the span of the steel frame is large, it will cause the support, and thus the workbench cannot be installed to the expected position and height, or many structural components need to be added to install the workbench to the expected position and height

In addition, if the other ends of the first connection part 5a and the second connection part 5b are not fixed, not only the stability of the workbench 4 is poor, but also the workbench 4 and the loads of the maintenance personnel who board the workbench will pass through the first connection. The part 5a and the second connecting part 5b are applied to the guide rail 2, forming a large moment on the guide rail 2, which may cause the guide rail 2 to deform

Although by increasing the rigidity and strength of the guide rails, the stability of the work platform can be improved and the deformation of the guide rails can be prevented, but as mentioned above, this will greatly increase the cost of the elevator installation
