Problems solved by technology

[0004] However, these protective measures are not foolproof, and there are still accidents in China where elevators fall
What's more serious: once the elevator falls, the occupants will face serious life-threatening dangers.
[0005] At the same time, the protective measures in the field are almost all concentrated in the preventive field, that is: how to prevent the elevator from falling; Lack of corresponding follow-up protection plan

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, detailed description will be given below in conjunction with the accompanying drawings and embodiments. It should be understood that the invention examples specifically described here are only used to explain the present invention, but not to limit the present invention.

[0037] Such as figure 1 and figure 2 As shown, the unloading and variable resistance damping structure 1 includes a fixed module 2 and a mobile module 3, the mobile module 3 is movably fitted on the fixed module 2, one end of the mobile module 3 is connected to a steel wire rope 17, and the other end is suspended in the air or subjected to the impact and extrusion of an external object The external object contacts and pushes the mobile module 3 to move relative to the fixed module 2, driving the mobile module 3 to move with variable resistance, realizing the unloading of the wire rope, and then realizing...

Abstract

The invention discloses an unloading and variable-resistance damping structure for a steel wire rope. The structure comprises a fixed module and a movable module, and the movable module is sleeved with the fixed module through a square sliding rod to achieve relative sliding. A fixed electromagnet is arranged at one end of the fixed module, a movable electromagnet is arranged at one end of the movable module, and a movable pulley is arranged at the other end of the movable module and plays a role of a tensioning wheel. An external object makes contact with and pushes the movable module to move relative to the fixed module, the movable module is driven to move in a variable-resistance mode, and unloading and variable-resistance damping of a steel wire rope are achieved. When an external object does not make contact with the movable module, the steel wire rope is tensioned. The unloading and variable-resistance damping structure has the functions of variable-resistance damping, unloading, double unloading, rebound preventing and automatic resetting.

Description

technical field [0001] The invention relates to a structure for rope force unloading and object buffering and shock absorption, in particular to a structure for variable resistance shock absorption for moving objects during the unloading process. Background technique [0002] In the field of transmission, common transmission methods include screw drive, sprocket drive, wire rope drive, belt drive, etc. Among them, wire rope transmission is widely used in occasions with large loads and long strokes, such as elevator lifting and crane loads. [0003] Take elevator take-off and landing as an example, in order to improve the safety of the elevator, multiple steel wire schemes are often used in the elevator scheme and accompanied by complex electronic control procedures to prevent falling accidents when the elevator fails. [0004] However, these protective measures are not foolproof, and there are still accidents in China where elevators fall. What's more serious is: once the ...
