Description

Technical Field

[0001] The invention relates to the technical field of anti-rope-off prevention for a reel, and in particular to a novel anti-rope-off prevention device for a reel and a rope-off signal detection device. Background Art

[0002] The prior art anti-rope-slipping device is equipped with a nylon block on the upper part. When the wire rope jumps out of the groove, the nylon block forces the wire rope to be pressed onto the drum, but there is no signal feedback. The operator cannot identify that the wire rope has failed, and the lifting mechanism cannot stop in time, causing the accident to expand. There is also an anti-rope-slipping device that does not strictly have the anti-rope-slipping function. It only triggers a signal to the limit when the wire rope is slipping off. The lifting mechanism can stop the action when it detects the signal, and personnel can carry out maintenance. However, if the wire rope is slipping off and this equipment does not have the ability to press the wire rope into the drum groove, it will cause inconvenience to the maintenance personnel. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of drum anti-rope derailment and rope derailment signal detection device. When the wire rope is derailed, the wire rope will first drive the rocker arm to press the pressure sensor, thereby triggering a signal, and the lifting mechanism is controlled to stop quickly through an external PLC controller, followed by a second layer of protection. The anti-derailment block on the block bracket is rigidly connected to the trolley frame. The anti-derailment block can force the wire rope to prevent it from derailing. The maintenance personnel only need to observe whether the lifting mechanism is damaged and whether it affects the normal lifting, and then determine whether maintenance is needed. The wire rope will not be derailed from the beginning to the end. It is not only convenient to operate but also safer.

[0039] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Please refer to Figures 1 to 3 As shown, an embodiment of the present invention provides a novel device for detecting a rope-off-proof drum and a rope-off-signal, comprising: a base 1, a detachable first bracket 2 is arranged on the top of the base 1, a detachable block bracket 4 is mounted on the first bracket 2, an anti-off-proof block 3 for limiting the position of the wire rope on the winding roller 7 is mounted on the block bracket 4, a second bracket 5 is mounted on the block bracket 4, and a rotatable swing rod 6 is mounted on the second bracket 5;

[0041] By adopting the above technical solution, when the wire rope is out of the groove, the wire rope will first drive the rocker arm 6 to press onto the pressure sensor 601, thereby triggering a signal, and the lifting mechanism is controlled to stop quickly through the external PLC controller, followed by the second layer of protection. The anti-slip block 3 on the block bracket 4 is rigidly connected to the trolley frame. The anti-slip block 3 can force the wire rope to prevent it from slipping out of the groove. The maintenance personnel only need to observe whether the lifting mechanism is damaged and whether it affects the normal lifting, and then determine whether maintenance is needed. The wire rope will not slip out of the groove from beginning to end, which is not only convenient to operate but also safer.

[0042] Please refer to Figures 1 to 3 As shown, a first mounting plate 101 is fixedly connected to the top of the base 1, and a second mounting plate 1011 used in conjunction with the first mounting plate 101 is installed at the bottom of the first bracket 2 and at a position corresponding to the first mounting plate 101, and the first mounting plate 101 and the second mounting plate 1011 are fixedly connected by a first bolt 102 and a first nut 1021. The convenience of disassembly and assembly of the first bracket 2 of the base 1 is increased by arranging the first mounting plate 101, the second mounting plate 1011, the first bolt 102 and the first nut 1021.

[0043] A first washer 103 is also provided on the first bolt 102 , and the locking stability of the first bolt 102 and the first nut 1021 is increased by providing the first washer 103 .

[0044] Please refer to Figures 1 to 3As shown, the first bracket 2 and the stopper bracket 4 are fixedly connected by the second bolt 201 and the second nut 2011. The second bolt 201 and the second nut 2011 are provided to increase the convenience of assembling the first bracket 2 and the stopper bracket 4.
