Pit-free elevator reformed and additionally mounted in old residential building

Abstract

The invention relates to a pit-free elevator, in particular to a pit-free elevator reformed and additionally mounted in an old residential building. The pit-free elevator comprises derrick stand columns, a derrick cross beam used for stabilizing the derrick stand columns, and an elevator car arranged between the derrick stand columns in a sliding mode. A bottom falling damping device is arranged at the bottom of the elevator car, and the derrick stand columns are buried on a multi-layer force holding structure below the outdoor ground plane in a supporting mode. The elevator is the pit-free elevator. The lowest point where the elevator car arrives is located above the elevation position of a unit canopy, the bottom of the elevator car is provided with the bottom falling damping device andthe derrick stand columns which are supported on the multi-layer force holding structure buried below the outdoor ground plane, the structures can play a role in damping and noise reduction in the elevator running process, and interference to residents on a first floor is reduced.

Description

technical field [0001] The invention relates to an inorganic-pit elevator, in particular to an inorganic-pit elevator retrofitted and installed in old residential buildings. Background technique [0002] In order to comprehensively improve the quality of life of residents in old communities, and to do a good job in the renovation and upgrading projects of old communities, it is very important to install elevators in old communities, especially for the elderly with inconvenient legs and feet.
