Description

Side-mounted type direct towing-to-single-winding passenger ladder with machine room

Technical Field

The utility model relates to the technical field of passenger elevators, in particular to a passenger elevator with a side-mounted type direct towing changed into a single winding machine room.

Background

In the former 1 ton elevator for organic tenants, because the technology of a gearless tractor is not mature at that time, the elevator is designed according to a 1:1 direct-dragging mode by adopting a geared tractor. At present, the old elevator can not be matched after a plurality of electric accessories are damaged due to long service life. If safety features are involved, modifications are required. Must be accepted according to the current new elevator standard. The new elevator must meet the requirements of parameter ranges and configuration tables in the special equipment type test certificate of the elevator manufacturer. The existing elevator for the tenant has only one report as long as the style and parameters meet the requirements regardless of the tonnage. The 1:1 direct-driven passenger elevator is expensive due to the gear traction machine, energy consumption is not saved, traction and traction power is high, and a matched electric control cabinet and electricity are expensive. The straight drag style structure is now eliminated. The old elevator can be repaired when a problem occurs, and a new elevator is removed and replaced if the problem occurs. The passenger elevator with the direct dragging structure has the advantages of high energy loss, high dragging required power and high electrical cost due to the adoption of the gear traction machine. The structure is eliminated by elevator manufacturers, so that no new standard elevator form test report exists. However, once the safety parts of the old elevator have problems and cannot be repaired, if the old safety parts are directly purchased, the old products of the current suppliers stop producing, and the elevator manufacturers cannot purchase the old products, so that the old elevator must be checked and accepted according to the new standard elevator once being replaced.
