Elevator traction machine frame device and elevator including the device

Abstract

The invention relates to an elevator traction machine rack device and an elevator comprising the same. The elevator traction machine rack device comprises a first connecting plate (2), a damping element (3), a second connecting plate (4) and a single machine carrying beam (6). A traction machine (1) is fixed to the upper surface of the first connecting plate (2). The second connecting plate (4) isfixed to the upper surface of the machine carrying beam (6). The damping element (3) is fixedly mounted between the first connecting plate (2) and the second connecting plate (4). According to the traction machine rack device, the one machine carrying beam is adopted to replace two or more machine carrying beams of a traditional elevator, and the first connecting plate is adopted to replace a traction machine rack in the traditional elevator. The elevator traction machine rack device is simple in structure, convenient to install and capable of saving a large space occupied in a machine room (a machinery equipment room), providing a larger overhauling and operation space for other elevator components in the machine room and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to an elevator traction machine frame device and an elevator including the elevator traction machine frame device. Background technique [0002] The elevator traction machine frame device is one of the important parts of the elevator, which is related to the operation quality and safety of the elevator, and has always been valued by the industry. [0003] The traction machine frame device of the traditional elevator design mainly includes the traction machine frame, shock absorbing elements and two or more suspension beams, Figure 10 An elevator traction machine frame device in the related art is disclosed. The traction machine frame 1001 in the traction machine frame device is installed on two laying beams through a shock absorbing element 1002, and the traction machine 1005 is installed On the traction machine frame 1001. [0004] in addition, Figure 11 Another ...

AI Technical Summary

Problems solved by technology

[0005] The existing traction machine frame device has the following problems: when the traction machine frame device is installed in the machine room (machine room), it takes up a lot of space, which makes it difficult to arrange other equipment in the machine room, the maintenance space in the machine room is small, and The installation is labor-intensive; in addition, because the traction machine is directly installed on the traction machine beam without any shock absorption measures, the car vibrates and makes a lot of noise, which makes the occupants in the car less comfortable when riding on the elevator. Moreover, most of the vibration of the traction machine is transmitted to the shelf beam, which may lead to poor durability of the shelf beam of the traction machine; in addition, if Figure 12 As shown, since the traction sheave is set on the side of the shelving beam away from the wall, the horizontal projection of the force center of the traction sheave is in the position of the entire traction machine frame device (with the shelving beam as the main component) from the wall. Outside the polygonal area of ​​horizontal projection formed by each supporting point of the traction wheel, the entire traction machine frame device with the shelving beam as the main component will be subjected to a relatively large torque (because the horizontal projection of the force center of the traction sheave deviates from each The horizontal projected polygonal area formed by the support points, so the force arm is longer), its stress condition is not good, it is easy to cause poor durability of the shelving beam, and there is a risk of the traction machine tipping over
