Problems solved by technology

[0002] The detection device for the real-time safe operation of elevators pays more attention to the detection of overspeeding and exceeding the limit position in the industry. After detecting the relevant values, it will switch the traction machine and speed limiter in real time, so as to ensure the safety of the elevator. Safe operation, at home and abroad, this is a common and effective device for detecting the safe operation of elevators. However, for the protection of elevator broken ropes, it is mainly after the occurrence of a broken rope accident, that is, after the well-known broken rope, and then The elevator detects and responds, such as the speed is unstable after the rope is broken, the car falls and the safety gear of the speed limiter acts, etc. Obviously, this kind of protection lacks the ability to meet in advance
And GB7588-2003 has no specific requirements for this early monitoring
At present, although there are some schemes of broken rope monitoring devices, these monitoring devices have the disadvantages of complex structure, high manufacturing cost and large space occupation.

Embodiment 1

[0015] Example 1, see figure 1 , figure 2 , an elevator rope breakage monitoring device, including a plurality of rope ends 1 and travel switches 2, the rope ends 1 are movable through the end plate 9, and the rope ends 1 are located at the upper end of the end plate 9 through a pressure plate 10 and a nut 11. Compensation spring 12 for traction wire rope stretching; travel switch 2 is set on mounting plate 3, on which mounting plate 3 is hinged with swing rod 4, swing rod 4 is connected with mounting plate 3 through one end, and one side of swing rod 4 abuts On the self-resetting pressure head 2a of the travel switch 2, and locked by the elastic locking mechanism located on the other side of the swing rod 4; , the other end of the dragline 6 passes through a plurality of cords 1 in turn through the transverse perforations provided on the cord 1, the end of the dragline 6 is fixed to the cord 1 at the far end, and the dragline 6 is fixed and tightened by both ends.

Embodiment 2

[0017] Example 2, see image 3 , the locking member 5 and the mounting hole are both in a stepped structure, the diameter of the front section of the locking member 5 is smaller than that of the rear section, and the front end of the locking member 5 has a frustum structure; the corresponding side of the swing rod 4 is formed with a guide slope 4a.

[0018] The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

[0019] In the foregoing embodiments, the transverse perforation on the rope head 1 may also be provided at the upper end of the rope head 1 . Wherein, the stay cable 6 can adopt a single steel wire or a steel wire rope made of multiple strands of steel wire. The connection position between the drag cable 6 and the swing rod 4 can also be set on the rod section of the swing rod 4 between the L-shaped corner and the hinge point, so that the self-resetting pressure head 2a can be triggered to reset when the displ...

Abstract

The invention discloses an elevator rope head fracture monitoring device. The elevator rope head fracture monitoring device comprises a plurality of rope heads and a travel switch which is installed on an installing plate. An oscillating rod is hinged to the installing plate. One end of the oscillating rod is connected with the installing plate, and one side of the oscillating rod abuts against a self-reset pressing head of the travel switch, and is locked through an elastic locking mechanism located on the other side of the oscillating rod. The oscillating rod is connected with an inhaul cable, one end of the inhaul cable and the oscillating rod are fixed, and the other end of the inhaul cable sequentially penetrates the multiple rope heads through transverse penetrating holes formed in the rope heads. The tail end of the inhaul cable and the rope head located at the far end are fixed, and the two ends of the inhaul cable are fixed and tightened. Preferably, the elastic locking mechanism comprises a locking component installed in an installing hole formed in the installing plate, and the locking component is provided with a part capable of extending out of the installing hole. The rear end of the installing hole is in screw joint with an adjusting screw plug. A compression spring is arranged between the adjusting screw plug and the locking component. The elevator rope head fracture monitoring device has the beneficial effects of being simple in structure, convenient to manufacture and install and small in occupied space.

Description

technical field [0001] The invention relates to an elevator safety monitoring device, in particular to an elevator rope head breakage monitoring device. Background technique [0002] The detection device for the real-time safe operation of elevators pays more attention to the detection of overspeeding and exceeding the limit position in the industry. After detecting the relevant values, it will switch the traction machine and speed limiter in real time, so as to ensure the safety of the elevator. Safe operation, at home and abroad, this is a common and effective device for detecting the safe operation of elevators. However, for the protection of elevator broken ropes, it is mainly after the occurrence of a broken rope accident, that is, after the well-known broken rope, and then The elevator detects and reacts, such as the speed is unstable after the rope is broken, and the safety gear of the speed limiter operates due to the car falling. Obviously, this kind of protection l...
