Problems solved by technology

However, the spring damping method is single, and the existing spring rope head device cannot detect the change of the tension force of the wire rope in real time, and the change of the tension force of the wire rope has a great impact on the safety and stability of the car operation. The tension changes to ensure the safe and comfortable operation of the elevator

Embodiment 1

[0036] Such as figure 1 As shown, the static magnetic assembly includes a fixed base sleeve 35 and a lower magnet 34 , one end of the fixed base sleeve 35 is vertically fixed on the rope head plate 70 , and the lower magnet 34 is fixed on the other end of the fixed base sleeve 35 .

[0037] The movable magnetic assembly includes a pull rod 10 and an upper magnet 32, and one end of the pull rod 10 vertically passes through the lower magnet 34 and is enclosed within the sleeve, and is connected with one end of the rope end taper 50 at the same time, and the end of the rope end taper 50 The other end is connected with the wire rope 60 ; the upper magnet 32 ​​is fixed on the other end of the pull rod 10 .

[0038] The position-limiting structure is a frame body fixed on the pull rod 10 and enclosing the upper magnet 32 ​​and the lower magnet 34 inside. length.

[0039] Specifically, the frame body is a square, and the frame body includes a sleeve 33 and a backing plate 31, the b...

Embodiment 2

[0047] Such as figure 2 As shown, this embodiment discloses another elevator wire rope end device. In terms of structure, the difference between it and the elevator wire rope end device described in Embodiment 1 lies in the fact that the generation of the magnetic field is different.

Abstract

The invention relates to the technical field of elevators and in particular to an elevator steel wire rope head device and a method for detecting steel wire rope tension by using the device. The device specifically comprises a rope head plate, a static magnetic component fixed on the rope head plate, and a moveable magnetic component which is repellent with the static magnetic component in magnetism and suspended relative to the static magnetic component. Between the static magnetic component and the moveable magnetic component, a limiting structure for limiting a relative distance of two parties is installed. One end, fixed on the rope head plate, of the static magnetic component is connected with a steel wire rope through a connecting piece. The magnetic component is provided with a detecting device for detecting a magnetic suspension force. The device is capable of overcoming a technical problem that a vibration reducing mode of a current spring rope head device is single, and the steel wire rope tension cannot be detected in real time, advantageously realizing intelligent monitoring to an elevator running condition, and guaranteeing safety and comfort of elevator running.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator wire rope end device and a method for detecting the tension of the wire rope. Background technique [0002] In the existing elevator technology, the elevator car and the counterweight are mainly connected by wire ropes, and the up and down movement of the car is realized under the drive of the traction machine. The two ends of the elevator steel wire rope are connected to the frame through the rope head device. In addition to fixing the two ends of the wire rope, the rope head device also uses springs to buffer the vibration of the elevator during operation and maintain the tension of the wire rope. However, the spring damping method is single, and the existing spring rope head device cannot detect the change of the tension force of the wire rope in real time, and the change of the tension force of the wire rope has a great impact on the safety and stability of the ...
