Problems solved by technology

[0012] However, the overall structure of the existing elevator is relatively large, and there must be a space for installing the control cabinet above the top floor of the elevator, and the traction machine is installed in this space And speed limiter and other main elevator components, resulting in the existence of defects such as complex structure, high cost, large transmission loss, and large energy consumption

Embodiment

[0037] The machine-roomless elevator of the present invention is a new type of elevator produced with the development of traction technology and the requirements of energy saving and environmental protection. It is to install the traction machine and speed limiter among the elevator components in the elevator shaft to control The cabinet is installed beside the door of the top floor of the elevator, thus compressing the machine room in the elevator shaft.

[0038] The improvement of the installation structure of machine room-less elevators is different from that of machine-room elevators. In the case of machine-room-less elevators with higher transmission ratio, 2:1 rewind wheels are installed on the two corners of the lower middle of the car to save the space on the top of the hoistway and reduce the height of the top floor.

[0039] Because the conservative coefficient of the traction machine of the machine-roomless elevator is small, the moment of inertia of the entir...

Abstract

An elevator without an engine room mainly comprises a traction system, a guide system, an elevator car, a door system, a weight balancing system, an electric drive system, an electric control system and a safety protection system. A tractor of the traction system and a speed governor of the safety protection system are mounted in a shaft of the elevator. A control cabinet of the electric control system is mounted on the topmost hoistway door of the elevator so that the engine room is compressed in the shaft of the elevator. A permanent magnet gearless synchronous tractor is used as the tractor. Frequency conversion of the permanent magnet gearless synchronous tractor is controlled by a microcomputer. Transmission of the tractor is independent of a gearbox, so that transmission wastage is reduced greatly. Movable block transmission is used as a traction manner of the tractor. A diversion sheave which is used for rewinding of steel wire ropes of a traction system are mounted at two corners in the lower middle of the elevator car, so that top space of the shaft is saved, and top layer height is reduced. The elevator without the engine room has the advantages of simple structure, convenience to mount and use, reliability, low manufacture cost, capability of lowering energy consumption and the like.

Description

technical field [0001] The invention relates to a machine room-less elevator for carrying passengers or goods, and belongs to the technical field of elevators. Background technique [0002] figure 1 As shown, the traditional elevator can be divided into four parts from the spatial location: the machine room and shaft attached to the building, the car carrying passengers or goods, and the landing station where passengers or goods enter and exit the car, namely the machine room, shaft, car, floor stand. From the function of each component of the elevator, it can be divided into eight parts: traction system, guidance system, car, door system, weight balance system, electric drive system, electrical control system and safety protection system, of which: [0003] (1) Electric drive system: It is composed of motor, reducer, brake, power supply system, speed feedback device and speed regulating device, etc., to realize speed control and provide driving force with elevator; [0...
