Description

Technical Field

[0001] The invention relates to the technical field of wire rope broken wire and detached strand detection, and in particular to an online wire rope broken wire and detached strand intelligent detection device for a lifting wire rope. Background Art

[0002] Lifting wire rope is mainly used on lifting equipment, such as lifting pulleys, electric hoists, bridge cranes, etc. If the lifting wire rope has broken wire and separation defects, its strength will be greatly reduced. Lifting equipment is often used to lift objects weighing several tons. If a wire rope with the above defects is used, it will cause a major accident with disastrous consequences. Therefore, although the production technology of lifting wire rope is becoming more and more advanced and there is rarely a phenomenon of broken wire and separation, it is still necessary to carry out broken wire and separation detection before it leaves the factory to avoid products with this defect from entering the market. Detection equipment is needed to detect the wire rope.

[0003] However, the detection method of existing devices is often to detect the broken wires and strands of the wire rope by mechanical detection based on the change in the diameter of the wire rope. However, in many cases, the sensitivity of mechanical detection is not high and it is easy to miss some places where the broken wires and strands are not obvious.

[0004] The prior art CN113566901A relates to the technical field of intelligent wire rope detection, and provides an online intelligent detection device for broken wire and stranded wire of a lifting wire rope, comprising: a device housing, with rope passage grooves on the same axis provided at both ends; a drive assembly installed inside the device housing, and two groups of drive assemblies are respectively located on both sides of the inside of the device housing; a broken wire and strand detection assembly, including a diameter detection assembly, a burr detection assembly, a central control module and an alarm; this technical solution has a complex structure and is operated using multiple drive assemblies, which increases the risk of failure to detect when the power source disappears.

Piece 13, when the wire rope passes through the detection device 7, when the wire rope breaks and separates from the strands, the diameter of the wire rope changes, and the broken wire rope contacts the wire rope. When the wire rope continues to move forward, it will drive the second hinge block 11 to rotate through the insert piece 13, so that the second hinge block 11 drives the second magnet block 23 to rotate through the rod body 12. Since the second magnet block 23 is magnetically attracted to the first magnet block 20, even if the rod body 12 rotates a very small angle, the second magnet block 23 and the first magnet block 20 will be attracted together due to the magnetic force, thereby improving the sensitivity of the detection device 7, and further the second magnet block 23 causes pressure on the switch 22.

[0035] In this embodiment, please refer to Figure 2 and Figure 6 The slider 16 is provided with a cylinder 15 on its outer sleeve, and the cylinder 15 is slidably connected to the slider 16.

The use of multiple compression devices 6 can make the wire ropes between the compression devices 6 slide more smoothly, avoid shaking of the wire rope, and improve the accuracy of broken wire separation.

[0036] In this embodiment, please refer to Figures 3 to 5 A first clamping block 24 is provided on one side of the plug 13, and a second clamping block 25 is provided on the other side of the plug 13. The first clamping block 24 and the second clamping block 25 are both fixedly connected to the semicircular ring block 9. The plug 13 is provided with a slot 14, and a plug block 26 is provided in the slot 14.

[0037] In this embodiment, please refer to Figure 1The base 1 is fixedly connected with an electric steel cable winch 2, which is connected to the switch 22 circuit through a wire. When the switch 22 is pressed, the electric steel cable winch 2 is in a non-working state. The top of the box 4 is fixedly connected with a warning light 3, which is connected to the switch 22 circuit through a wire. When the switch 22 is pressed, the warning light 3 is in a working state. When the switch 22 is pressed, the electric steel cable winch 2 stops winding the wire rope, and the warning light 3 lights up.

[0038] Working principle of the present invention:

[0039] When in use, the steel wire rope to be tested is passed through the detection device 7 and then wound on the electric steel cable winch 2. The power of the electric steel cable winch 2 is turned on, and the electric steel cable winch 2 starts to wind the steel wire rope. The steel wire rope moves forward. When the steel wire rope breaks and separates from the strand, the diameter of the steel wire rope changes. The broken steel wire rope contacts the plug. When the steel wire rope continues to move forward, it drives the second hinge block 11 to rotate through the plug 13, so that the second hinge block 11 drives the second magnet block 23 to rotate through the rod body 12. Since the second magnet block 23 is magnetically attracted to the first magnet block 20, even if the rod body 12 is rotated at a very small angle, the second magnet block 23 and the first magnet block 20 are still attracted to each other. The blocks 20 will also be attracted together due to magnetic force, thereby improving the sensitivity of the detection device 7. The second magnet block 23 further compresses the switch 22. When the switch 22 is compressed, the electric cable winch 2 stops winding the wire rope, and the warning light 3 lights up to remind the worker that the wire rope is broken or separated from the strand. The use of multiple compression devices 6 can make the wire ropes between the compression devices 6 slide more smoothly, avoid shaking of the wire rope, and improve the accuracy of broken wire separation. The plug 13 is connected to the semicircular ring block 9 by a snap-on method, so that the plug 13 can be replaced to adapt to the detection of wire ropes of different lengths.
