Elevator with weightlessness safeguard device

Abstract

The invention discloses an elevator with a weightlessness safeguard device. The elevator comprises an elevator car and the weightlessness safeguard device, wherein the weightlessness safeguard devicecomprises a handrail, a first transmission rod, a second transmission rod, two positioning and guiding holes and two damping rods, wherein the handrail is hinged to the elevator car; the first transmission rod is hinged to the transmission input end of the handrail in a matching mode and extends to the bottom of the elevator car; the second transmission rod is hinged to the lower part of the elevator car, and is hinged to the first transmission rod in a matching mode; the two positioning and guiding holes are formed in the bottom of the elevator car; and the two damping rods are arranged at the bottom of the elevator car and penetrate through the two positioning and guiding holes respectively, the two damping rods are hinged to each other, the end parts, far away from the hinged part, of the two damping rods penetrate through the corresponding positioning, the two damping rods are provided with damping ends which extend to the plane where the side wall of the elevator car is located, and the two damping rods form an upward-opened obtuse angle structure at the hinged part. According to the elevator with the weightlessness safeguard device, the structure is simple, complete mechanical operation is achieved, any electronic component is not needed, and therefore the situation that the electronic component is unstable in work is avoided, and the safety coefficient of the elevator isgreatly improved.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator with a weightlessness protection device. Background technique [0002] Elevator refers to serving several specific floors in a building, and its car mainly runs in the vertical direction. Hydraulic elevators began to appear in the middle of the 19th century, and they are still used in low-rise buildings. And with the improvement of technology, the development of elevator technology has become more and more mature and safe. By the end of the 20th century, the elevator used permanent magnet synchronous traction machine as power, which greatly reduced the area occupied by the machine room, and has the advantages of low energy consumption, energy saving and high efficiency, and high lifting speed. Fast and other advantages have greatly promoted the development of real estate in the direction of super high-rise buildings. [0003] Since the existing elevator technology is mature, especially...

Problems solved by technology

[0004] However, the elevators used in the society will encounter weightlessness due to external power supply or the quality of the elevator itself during use - that is, the situation of free fall

Although there are many methods on the Internet on how to minimize the damage to the human body when the elevator is weightless, such as leaning against the inner wall of the elevator and bending the legs slightly, these methods are all passive protection, and they use the human body to withstand the acceleration of the falling body , is really the only protection solution in desperation
