Machine-room-less elevator transformation method and machine-room-less elevator

Abstract

The invention relates to a machine-room-less elevator transformation method and a machine-room-less elevator. The machine-room-less elevator transformation method comprises the following steps that anoriginal traction machine of a hoistway pit and all top hanging wheels at the top of a hoistway are dismantled; the traction machine is installed at the top of the hoistway, and one top hanging wheelis installed at the other position of the top of the hoistway; the other top hanging wheel is installed in the hoistway pit, or a new diversion sheave is installed in the hoistway pit to form a pit diversion sheave; even in rainstorm weather, accumulated water in the hoistway pit cannot immerse the traction machine on the top of the hoistway, so that the traction machine is prevented from being damaged, and the failure rate of the elevator is reduced. Therefore, the maintenance cost caused by water immersing damage can be saved, and the normal operation of the machine-room-less elevator can be ensured. Moreover, the top hanging wheel at the top of the hoistway is dismounted, and meanwhile, a plurality of hoistway components of an original machine-room-less elevator are reserved and can still be used for the new machine-room-less elevator, so that the transformation cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a method for transforming a machine-room-less elevator and a machine-room-less elevator. Background technique [0002] In machine room-less elevators, the traction machine is usually installed in the shaft pit, and the shaft pit is often the lowest position in the building. When encountering rainstorms, it is very easy for rainwater to seep into the pit of the well. If the accumulated water in the well is not cleaned up in time, the traction machine will be soaked in the rainwater, and the traction machine will be easily damaged. As one of the core components of the elevator, the traction machine will cause the elevator to fail to operate normally and affect the use of users. At the same time, the maintenance of the damaged traction machine will increase the maintenance cost. Moreover, even after the elevator is repaired and restored to use, the same problem will still occur i...

AI Technical Summary

Problems solved by technology

When encountering heavy rain, the bottom pit of the hoistway is very easy to seep into rainwater. If the accumulated water in the hoistway is not cleaned up in time, the traction machine will be soaked in rainwater and the traction machine will be easily damaged.

The traction machine is one of the core components of the elevator, and its damage will cause the elevator to fail to operate normally and affect the user's use. At the same time, repairing the damaged traction machine will increase the maintenance cost

Moreover, even after the elevator is repaired and restored to use, the same problem will still occur if it encounters heavy rain again, which will greatly affect the use of users.
