Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an anti-tipping device for elevator traction machines. Background Technology

[0002] With the development of science and technology, many buildings have become landmarks of cities. For these landmark buildings, elevators, as a means of vertical transportation, are responsible for transporting people and goods.

[0003] The elevator traction machine is the power unit of the elevator, and its safety and stability directly affect the overall operational safety of the elevator. During elevator operation, the traction machine is subjected to the tension of the car and counterweight, which can cause it to tilt. Under test conditions such as safety brake braking and bottom stopping, it is prone to overturning. The traction machine frame, as the fixing device for the traction machine, not only needs to ensure the traction machine is securely and reliably installed, but also needs a reasonable structural design to prevent the traction machine from overturning. Existing anti-overturning structures have relatively fixed installation methods, making it impossible to disassemble them later, and even if disassembly were possible, it would require a significant amount of time and effort.

The pressure guide plate and the flat section are connected by a first bolt assembly passing through the pressure guide plate and the adjustment hole. A connector connected to the frame beams is provided above the middle section, and the middle section and the connector are connected by a second bolt assembly.

[0007] Preferably, the adjustment hole is an elongated hole, and the extension direction of the elongated hole is the width direction of the machine beam.

A frame 2 is mounted on the machine beams 1, and a traction machine 3 is mounted on the frame 2. The frame 2 includes two parallel, spaced-apart frame beams 21, which span the machine beams 1 and are connected to them to form a square structure. A bracket 4 is mounted on one side of each frame beam 21, as shown in the attached diagram. Figure 2 Appendix Figure 3 As shown, the bracket 4 includes two flat sections 41 that fit against the upper surface of the machine beam 1 and an arched intermediate section 42 connected between the flat sections 41. The flat sections 41 have adjustment holes located on the outer side of the machine beam 1. Below the flat sections 41 is a pressure guide plate 5 for securing the edge of the machine beam 1. The pressure guide plate 5 and the flat sections 41 are connected by a first bolt assembly 6 passing through the pressure guide plate 5 and the adjustment hole.
