Elevator lower beam structure with car bottom wheels

Abstract

The invention discloses an elevator lower beam structure with car bottom wheels. The elevator lower beam structure comprises a car frame lower beam (1), and two car bottom wheel fixing seats (6) distributed at the two ends of the car frame lower beam (1) are arranged at the bottom of the car frame lower beam (1). The car bottom wheels are arranged on the car bottom wheel fixing seats (6) respectively. One end of an axle of each car bottom wheel (2) is fixed to the corresponding car bottom wheel fixing seat (6), and the other ends of the axles are fixed to the bottoms of car bottom wheel supporting pieces (4). A buffer plate (3) is fixed to the middle of the bottom of the car frame lower beam (1). The car bottom wheel fixing seats (6) are of a hollow structure, and safety tongs (5) are arranged in the car bottom wheel fixing seats (6). Notches corresponding to tong openings of the safety tongs (5) are formed in the upper ends and the lower ends of the car bottom wheel fixing seats (6). The elevator lower beam structure is simple, high in space utilization rate and small in occupied height, and therefore the requirement of an elevator for pit depth can be reduced, and then civil engineering cost is reduced.

Description

technical field [0001] The invention relates to an elevator lower beam structure including car bottom wheels, belonging to the technical field of elevators. Background technique [0002] The elevator car frame of the present machine-room-less elevator is generally composed of a car frame lower beam assembly, two car frame upright beams, and an upper beam assembly, wherein the car frame lower beam is horizontally arranged at the bottom of the elevator car, and the two car frame vertical The bottom ends of the beams are respectively fixedly connected to the two ends of the lower beams of the car frame. The car frame lower beam of an elevator without a machine room needs to be equipped with many structures such as safety gear and car bottom wheels, but the existing car frame lower beam has a relatively complicated structure and occupies a large height, so this also requires the depth of the elevator pit to be It must be enlarged accordingly, which increases the civil construct...
