[0033] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0034] Embodiment 1, please refer toFigures 1-4 The steel wire rope detection device comprises a rope head plate 1 and a plurality of rope head combinations 101 arranged on the rope head plate 1, a detection mechanism is arranged between the rope head plate 1 and the plurality of rope head combinations 101, the detection mechanism comprises a plurality of small supports 2, a trigger part 10 and a sensing part 11 arranged on the rope head plate 1, the plurality of small supports 2 are arranged on the plurality of rope head plates 1 respectively, the rope head combination 101 rises when the steel wire rope is broken to drive the trigger part 10 to act, and the trigger part 10 triggers the sensing part 11; through the detection mechanism, the rope head combination 101 rises when the steel wire rope is broken to drive the trigger part 10 to act, and then the trigger part 10 triggers the sensing part 11 to realize broken wire detection, so that the abnormal elongation or breakage of the steel wire rope can be found in time, and the occurrence of more serious accidents can be reduced.

[0035] Further, as shown in Figures 1-4 The sensing part 11 comprises a second support 8 arranged on the top of the rope head plate 1, and a swing lever switch 9 arranged on the second support 8, the swing lever switch 9 can generate a signal when being touched, and the swing lever switch 9 is touched when the steel wire rope is broken, the swing lever switch 9 is adjusted simply, the installation time is greatly shortened, and the installation difficulty is reduced.

[0036] Further, as shown in Figure 2 The second support 8 is provided with a second elongated opening 13, the swing lever switch 9 is arranged on the second support 8 through bolts and the second elongated opening 13, the design of the second elongated opening 13 gives the swing lever switch 9 high flexibility, in different equipment models, different installation environments and different steel wire rope tension settings, the position of the swing lever switch 9 on the second elongated opening 13 can be adjusted to realize the matching of the swing lever switch 9 and the trigger part 10, the adaptability adjustment capability greatly widens the application range of the steel wire rope detection device, makes the steel wire rope detection device can accurately play the detection function in various complex industrial scenes, effectively reduces the detection error or failure risk caused by environmental factors, improves the overall detection precision and reliability of the equipment, and guarantees the safe operation of the equipment in the whole life cycle.

[0037] In embodiment 2, the steel wire rope detection device provided in embodiment 1 is further optimized, specifically, as shown in Figures 1-2As shown, the trigger part 10 includes a support provided on the top of the rope head plate 1, and the striking plate 7 is rotatably connected to the support. When the steel wire rope is abnormally elongated or broken, the striking plate 7 can be lifted by the rope head plate 1 and the small support 2. The striking plate 7, the rope head plate 1 and the small support 2 form a sensitive linkage system. When the steel wire rope is abnormally elongated or broken, the linkage system can effectively amplify and transmit the subtle changes. Compared with the traditional direct trigger detection structure, the indirect linkage amplification mechanism significantly improves the detection sensitivity, can capture the changes of the steel wire rope, and early warning potential risks. It effectively avoids the fault deterioration caused by the initial fault of the steel wire rope which is not easy to detect, ensures the safe and stable operation of the equipment in the whole life cycle of the steel wire rope, and reduces the high maintenance cost and production loss caused by sudden serious failure of the steel wire rope.

[0038] Further, the rope head combination 101 rises to drive the striking plate 7 to act when the steel wire rope is elongated or broken, so as to trigger the swing lever switch 9. The direct physical linkage mode effectively reduces the interference and loss in the signal transmission process, and ensures that the swing lever switch 9 can accurately receive the fault signal from the steel wire rope.

[0039] Further, as shown in the Figures 1-2 small support 2 is located below the striking plate 7, which ensures that the striking plate 7 is in a stable initial position when it is not triggered, and reduces the false action caused by external factors. At the same time, the small support 2 can provide lifting force for the striking plate 7 during the triggering process, so that the striking plate 7 can rotate and rise according to the predetermined mechanical motion track, and accurately trigger the swing lever switch 9.

[0040] Further, the small support 2 is installed at the top end of the rope head combination 101 through a nut. The nut installation mode gives the small support 2 high installation flexibility and accuracy. During installation, the technician can easily adjust the height position of the small support 2 by simply rotating the nut, so as to ensure that all the small supports 2 are in the same horizontal plane, thereby ensuring that the lifting force received by the striking plate 7 at each trigger point is uniform. This precise installation and adjustment capability is only beneficial to improve the initial installation accuracy of the detection device and reduce the detection deviation caused by installation errors.

[0041] Further, as shown in the Figures 1-2 support includes a first support 3 installed on the top of the rope head plate 1. One side of the first support 3 is provided with two connecting plates 4, and the two connecting plates 4 are connected with a latch 5. The striking plate 7 is sleeved on the outer surface of the latch 5. The first support 3 provides a solid foundation support, and the combination of the two connecting plates 4 and the latch 5 provides a rotating shaft for the striking plate 7, so that the striking plate 7 can perform circular motion around the latch 5 during the triggering process.

[0042] The steel wire rope detection device of the embodiment 3 is further optimized, in particular, as shown in Figure 2 The pin 5 is provided with an open pin 6 for limiting the pin 5.

[0043] Further, as shown in Figure 2 The first support 3 is provided with a first long-shaped opening 12 through which the outer surface of the beating plate 7 passes, the first long-shaped opening 12 provides the required space for the beating plate 7, and when the beating plate 7 rotates to the highest position, the top wall of the first long-shaped opening 12 can limit the beating plate 7, so that the beating plate 7 can remain in the rotated state under the action of the lifting of the small support 2 and the top wall of the first long-shaped opening 12, so as to continuously touch the swing lever switch 9.

[0044] The overall installation height of the application is compact, which is suitable for scenes such as inorganic rooms with relatively strict top layer height, and improves the space utilization rate of the elevator system.

[0045] The use process of the steel wire rope detection device is as follows:

[0046] The device is installed in the last stage of elevator installation, at this stage, each rope head combination 101 is subjected to pressure transmitted from the steel wire rope, and the height of the spring of the rope head combination 101 is lowered, at this time, the small support 2 of the device is installed on the rope head combination 101, and the nut is pressed and the height of the nut is adjusted, so that all the small supports 2 are on the same horizontal plane, and the beating plate 7 is located on the small support, when the steel wire rope has abnormal elongation or breakage, the corresponding rope head combination 101 is subjected to reduced or disappeared pressure transmitted from the steel wire rope, and the height of the spring of the rope head combination 101 is slightly recovered or directly recovered to the height without load, and the small support 2 installed on the rope head combination 101 is also raised to push the beating plate 7 to rise, at this time, the beating plate 7 makes a circular motion with the pin 5 as the center, due to the characteristics of the circular motion, the slight lifting of any small support 2 in the triggering area is amplified to the action area, so that the beating plate 7 in the action area has a larger swing, so that the swing lever switch 9 is more easily actuated, so that the breakage or abnormal elongation of the steel wire rope is detected.
