Abstract

The invention relates to a method for reforming an elevator without a machine room, and the elevator without the machine room, and the method comprises the following steps of removing a top hanging wheel on the top of an elevator shaft, and installing a new traction machine the original position of the top hanging wheel; and removing an old traction machine of a shaft pit, and installing the top hanging wheel in the shaft pit to form a pit diversion sheave. Since the new traction machine is installed on the top of the elevator shaft, even if rainwater leaks into the shaft pit in rainstorm weather, the new traction machine can not be in contact with or immersed in the accumulated rainwater; the traction machine can not be soaked in the rainwater, and safe and reliable work can be guaranteedall the time; the maintenance cost for damage due to immersion can be saved; and meanwhile, the normal operation of the elevator without the machine room can be ensured.

Description

Technical field [0001] The present invention relates to the field of elevator technologies, in particular to an inorganic room elevator modification method and an inorganic elevator. Background technique [0002] Currently, for most elevators, especially in-room elevators, the traction machine is installed on the bottom pit, and because the bottom pits are often the lowest place in the building, when the weather is encountered The bottom of the wellway is very easy to infiltrate into rain, and the rain is gradually accumulated, which will cause the traction machine soak in the rain. At this time, if you can't clean up the water in time, it will cause the traction machine for a long time, and the traction machine is damaged. It will not only increase the maintenance cost, but also damage and maintenance period, the elevator cannot operate normally, affect the user experience. Inventive content [0003] Based on this, it is necessary to provide a modification method of an inorgani...
