Problems solved by technology

[0003] At present, the lower beam of the machine-room-less elevator is composed of the main lower beam and the auxiliary lower beam. It is in contact with the bottom of the car with six-point bolts, and the contact surface is small. Moreover, the lower beam of this structure will cause the car frame to be straight. The beam is installed at a position away from the center of gravity of the car, that is, the center line connecting the two straight beams of the car frame is not on the same straight line as the center of gravity of the car, which will cause a large overturn of the car to the car guide rail when the safety gear is activated. Torque makes the car run unstable; it also makes the steel wire rope receive uneven force during the elevator operation, which affects the service life of the steel wire rope and increases the safety hazard of the elevator

Embodiment 1

[0023] figure 1 Shown is the lower view of the sub-beam structure installed on the car frame of the machine-room-less elevator according to the present invention. The auxiliary lower beam structure is installed at the bottom of the elevator car, and it includes a lower beam body 1 arranged horizontally, a lower beam body guide wheel assembly 2 arranged horizontally with the lower beam body, and a first fastener and a second fastener The firmware is the car floor bracket 3 fixedly connected with the lower beam body 1 and the lower beam body guide wheel assembly 2 respectively.

[0024] The first fasteners may be bolts fixedly connecting the lower beam body 1 and the car bottom bracket 3 at four points. The second fastening member is a bolt that fixedly connects the top surface of the lower beam body guide wheel assembly 2 and the lower end surface of the car bottom bracket 3 at eight points. In this way, the twelve-point support structure replaces the traditional six-point su...

Embodiment 2

[0027] Such as figure 2 , the car frame includes the above-mentioned auxiliary lower beam structure, the main lower beam 4, and two car frame straight beams 5. Both the auxiliary lower beam structure and the main lower beam are arranged at the bottom of the car, and the auxiliary lower beam structure is arranged in parallel with the main lower beam. The line connecting the centers of the straight girders of the car frame installed on both sides of the main lower beam is on the same straight line as the center of gravity of the car. In a specific application, the lower beam body 1 is arranged on the elevator car floor bracket 3, and two car frame straight beams connect the lower beam and the upper beam of the car frame. The existence of the lower beam guide wheel assembly 2 and the twelve-point supporting surface of the auxiliary lower beam structure increase the supporting surface between the lower beam structure and the car, thereby enhancing the stability of the car. When...

Abstract

The invention provides a secondary lower beam structure and a car frame of an elevator without a machine room, and belongs to the technical field of elevator devices. The secondary lower beam structure of the elevator without the machine room is arranged at the bottom part of an elevator car and comprises a lower beam body, a lower beam guide wheel assembly and a car bottom bracket; the lower beam body is horizontally arranged; the lower beam guide wheel assembly and the lower beam body are horizontally arranged; the lower beam body is integrally connected with the car bottom bracket through a first fastening part; the lower beam guide wheel assembly and the car bottom bracket are fixedly connected through a second fastening part; the lower beam body, the car bottom bracket and the lower beam guide wheel assembly form a supporting surface for stably supporting a car; the gravity center of the supporting surface is overlapped with the gravity center of the car. The car frame of the elevator without the machine room comprises the secondary lower beam structure of the elevator without the machine room. The secondary lower beam structure and the car frame of the elevator without a machine room are convenient to mount, high in strength, uniform to bear, high in stability and high in safety.

Description

technical field [0001] The invention relates to the technical field of an elevator device, in particular to a car anti-sheave machine room-less elevator sub-beam structure and a car frame installed on the car floor. Background technique [0002] The car frame of the present machine room-less elevator generally consists of a car frame main lower beam, auxiliary lower beam and two car frame straight beams, wherein the car frame main lower beam is horizontally arranged at the bottom of the elevator car, and the main lower beam and auxiliary lower beam The beams are generally arranged parallel or at an angle at the bottom of the elevator car, and the bottom ends of the two straight beams of the car frame are fixedly connected to the two ends of the lower beam and the upper beam of the car frame respectively. [0003] At present, the lower beam of the machine room-less elevator is composed of the main lower beam and the auxiliary lower beam. It is in contact with the bottom of th...
