Abstract

The invention provides an elevator without a machine room. The elevator without the machine room comprises a hoistway, a lift car and anti-falling devices. The hoistway comprises an insertion hole which is formed in the side wall of the hoistway. The anti-falling devices comprise a first anti-falling device and second anti-falling device. The first anti-falling device comprises a bolt which is arranged corresponding to the insertion hole and a baffle plate for covering the bolt; one end of the bolt is located in the lift car while the other end of the bolt perpendicularly passes through the side wall of the lift car and is opposite to the insertion hole; the second anti-falling device comprises a proximity switch, a controller and an electromagnet which are successively connected. The proximity switch is arranged in the insertion hole, the electromagnet comprises a main electromagnet which is fixedly arranged in the top of the hoistway and an auxiliary electromagnet which is fixedly arranged on the top of the lift car, and the main electromagnet and the auxiliary electromagnet which are galvanized attract each other; and the current comprises a direct current and an alternating current which attenuates gradually. According to the elevator without the machine room provided by the invention, the lift car is fixed by virtue of a double locking structure, so that the elevator without the machine room not only is good in safety, but also is convenient to use.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a machine room-less elevator. Background technique [0002] With the development of the economy, various high-rise buildings have sprung up. As a tool for moving up and down high-rise buildings, elevators greatly facilitate people's work and life. Due to the miniaturization of traction machines and electrical components and the rise of screw elevators, machine room-less elevators, which have the advantages of energy saving, environmental protection, and do not occupy space other than the hoistway, are becoming more and more popular. [0003] Many maintenance work of the existing machine-room-less elevators are carried out by raising the elevator car to the top of the elevator shaft, which is closed by the roof. Just enough room to complete the repairs. For those who work on the top of the car, there are always cases where the car is not firmly fixed on the top of the hoistwa...
