Description

A machine room-less elevator

technical field

The utility model relates to an elevator, in particular to a machine room-less elevator including a control cabinet.

Background technique

The machine room-less elevator is relative to the machine room elevator, that is to say, the machine room is omitted, and the control panel, traction machine, speed limiter, etc. in the original machine room are moved to the hoistway, etc., or replaced by other technologies. The characteristic of the machine room-less elevator is that there is no machine room, which reduces the cost for the builder. In addition, the machine-room-less elevator generally adopts frequency conversion control technology and permanent magnet synchronous motor technology, so it is energy-saving, environmentally friendly, and does not occupy space other than the shaft. In the history of the development of machine-room-less elevators, there are four generations in total. The first generation is a bottom-mounted type with a worm gear traction machine and a large shaft area; , so that the traction machine is installed in the middle of the elevator shaft; the third-generation machine-room-less elevator is a utility model of KONE, which uses a permanent magnet synchronous traction machine with a butterfly motor, which has made a fundamental development of the machine-room-less elevator, but due to The elevator traction machine is placed on the guide rail, which makes the elevator noise and vibration very loud; the fourth-generation machine-room-less elevator is the most advanced machine-room-less elevator, a utility model developed by WALESS, which makes up for the defects of the first three generations and raises the machine-room-less elevator to a higher level The load capacity has been greatly improved, and the safety performance and control technology have also been greatly improved.

At present, the elevator control cabinets in machine room-less elevators have the following four placement methods: 1) The main engine is placed on top. In this arrangement, the main engine is placed in the space between the car on the top floor of the well and the elevator shaft wall. The connection between the hosts is short enough. Generally, the control cabinet is placed next to the hall door on the top floor, which is also convenient for inspection and maintenance; In the projection space between the counterweights, the control cabinet generally takes the form of wall hanging. This placement method also provides convenience for inspection and maintenance; 3) The main engine is placed on the car, the main engine is placed on the top of the car, and the control cabinet is placed on the side of the car. In this arrangement, the number of accompanying cables is relatively large; 4) The location of the main engine control cabinet. The main engine and the control cabinet are placed in the opening space on the side wall of the hoistway. There should be an inspection door.

The Chinese utility model patent with application number CN201120038330.1 discloses an elevator machine room-less control cabinet, which includes a main control cabinet and an inspection cabinet, and the main control cabinet and the inspection cabinet are connected to each other through a communication interface , the main control cabinet is arranged in the elevator shaft, and the inspection cabinet is arranged on one side of a hall door of the elevator.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a machine room-less elevator provided by the utility model includes an elevator shaft, an elevator hall door 2 and an elevator control cabinet 1, and the elevator control cabinet 1 is horizontally Installed in the front wall above a certain elevator hall door 2, the elevator control cabinet 1 is partially or entirely placed in a parallelepiped space P, the size of the parallelepiped space P is defined by the above elevator hall door 2 The distance between the elevator shaft space and the elevator shaft walls on the left and right sides of the hall door is limited. The width of the front wall above the hall door is fixed, and the elevator control cabinet can be placed in the wall. During installation, a certain space is excavated in the wall to form a parallelepiped space P, and the control cabinet 1 is fixed in the wall. On the wall, the width of the control cabinet 1 can be changed according to the actual situation. The control cabinet 1 can be placed in the space as a whole, or part of the control cabinet can be placed in the space. When the whole is in the space, the width of the control cabinet 1 Should be less than or equal to the width of the front wall body 3, when the part is in the space, the width of the control cabinet 1 should be greater than the width of the front wall body 3.
