Problems solved by technology

[0004] At present, lifts are very popular and are mainly used in office buildings and residential buildings; however, while bringing convenience to people’s lives, there are also many potential safety hazards: 1. Traditional elevators usually use ropes for traction. When the rope breaks at a high floor, the elevator will plummet down, which is prone to major safety accidents and seriously threatens the lives of passengers; 2. When the power fails or the elevator fails, the elevator is stuck in the middle of the floor, and the passengers in the elevator can only wait. Rescue, unable to save oneself, prone to safety accidents

Embodiment Construction

[0033] The principles and features of the present invention will be described below in conjunction with the accompanying drawings and specific embodiments. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0034] Such as figure 1 As shown, the present invention provides a kind of safety cableless elevator, comprises elevator shaft 1 and elevator car 2, and the bottom lower end of elevator car 2 is provided with supporting device 3 and screw lifting device 4, and supporting device 3 is opposite to elevator car 2 Play the role of support, the screw lifting device 4 cooperates with the racks 5 on both sides of the elevator shaft 1 to drive the elevator up and down, the structure is simple, when the elevator fails, the screw lifting device 4 is stuck on the racks 5 on both sides of the elevator shaft , so that the elevator car 2 stays in the original place, avoiding the elevator car 2 straight down...

Abstract

The invention relates to a safe and cable-free elevator. The safe and cable-free elevator comprises an elevator shaft and an elevator car and is characterized in that a support device and a screw lifting device are arranged at the lower end of the elevator car, the screw lifting device is coordinated with toothed rails on the two lateral walls of the elevator shaft to drive the elevator car to ascend and descend, and a manual rescue device is arranged between the support device and the elevator car. The safe and cable-free elevator has the advantages that the elevator car is driven to ascend and descend by the coordination of screws and the toothed rails, the toothed rails clamp the elevator car when the elevator malfunctions, heavy casualties caused by straight descending when the cablesof an existing elevator break are avoided, and safety and reliability are achieved; meanwhile, the manual rescue device is arranged at the bottom of the elevator car, the manual rescue device is started to ascend the elevator car to an landing opening to allow passengers to escape conveniently when the elevator is stuck between floors, the passengers do not need to wait for rescue, and the life safety of the passengers is guaranteed; the toothed rails adopt sectioned small components to facilitate transportation and replacement; core stressed parts which are prone to damage are simplified, andthe elevator is convenient to maintain and low in maintenance cost.
