Elevator car bottom wheel mounting structure

Abstract

The invention provides an elevator car bottom wheel mounting structure, the elevator car bottom wheel mounting structure comprises a bottom beam and two sets of car bottom wheels, a rotating shaft is rotationally arranged in the middle of each car bottom wheel, the rotating shafts are connected with the bottom of the bottom beam through U-shaped bolts, a through groove is formed in the middle of the bottom beam, and the upper portions of the car bottom wheels are arranged in the through groove. The mounting structure is characterized in that the bottom and the outer side of each set of car bottom wheels are each provided with a blocking mechanism, each blocking mechanism comprises a bottom rope blocking shaft and an outer side rope blocking shaft, the front side and the rear side of each set of car bottom wheels are each provided with a vertical plate, the tops of the vertical plates are connected with the bottom of the bottom beam, the two ends of each bottom rope blocking shaft are connected with the two sets of vertical plates, the bottom rope blocking shafts are arranged below the bottoms of the car bottom wheels, and the bottom rope blocking shafts are arranged under the corresponding rotating shafts; the outer side rope blocking shafts are connected with the two sets of vertical plates through connecting mechanisms and arranged on the outer sides of the car bottom wheels. The safety of elevator operation is improved.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator car bottom wheel installation structure. Background technique [0002] The car elevator generally has a car top wheel structure and a car bottom wheel structure. Wherein, no matter which structure it is, when the elevator stops, the wire rope may break away from the bottom of the car top wheel or the car bottom wheel for an instant, and then return to the rope groove of the car top wheel or the car bottom wheel. But sometimes the steel wire rope breaks away too much, and the steel wire rope cannot return in the rope groove, and there is a larger potential safety hazard. Simultaneously, for the car bottom wheel structure, the wire ropes between the two groups of car bottom wheels are exposed, and the maintenance personnel may touch the wire ropes during maintenance, which poses a greater safety hazard. At the same time, when the car is counterweighted, it is directly installed on the t...

AI Technical Summary

Problems solved by technology

However, sometimes the wire rope is too much detached, and the wire rope cannot return to the rope groove, which poses a great safety hazard

At the same time, for the car bottom wheel structure, the steel wire rope between the two sets of car bottom wheels is exposed, and the maintenance personnel may touch the steel wire rope during maintenance, which poses a large safety hazard

At the same time, when the counterweight is installed on the car, it is directly installed on the top or bottom of the bottom beam, which will occupy more space at the bottom
