Description

Technical Field

[0001] This utility model relates to the field of port operation technology, specifically to a device for detecting tangled wire ropes on a drum. Background Technology

[0002] In the port lifting machinery industry, lifting cargo typically involves using a spreader to lift goods by winding wire rope onto a drum. However, due to the high lifting speed, when the spreader contacts the object, inertia often causes some of the wire rope to slack off from the drum. To ensure the wire rope winds smoothly and regularly, the drum is usually machined with wire rope guide grooves. When the spreader grabs the cargo and begins to lift, it first tightens the wire rope before lifting the object. If the slack wire rope does not correctly enter the guide groove, it will become tangled. If this is not detected in time, it can lead to the scrapping of the wire rope, resulting in significant economic losses. Furthermore, uneven winding and inconsistent rope lengths can cause serious safety accidents after lifting the cargo. Therefore, preventing safety accidents and avoiding unnecessary economic losses has become an issue we cannot ignore.

[0003] Currently, there are two main methods: one involves installing a light sensor at one end of the drum's bottom and a reflector at the other end to reflect the light. If the light is blocked, the wire rope is considered tangled, and the drum stops. However, in actual use, the wire rope surface often accumulates mud and dirt. When the drum rotates at high speed, this mud and dirt frequently splashes onto the sensor or reflector, causing false triggering and severely impacting production. The other method is mechanical tangled rope detection. A tangled rope detection device covering the entire drum is installed at an appropriate location at the bottom. When the wire rope becomes tangled, it collides with a trigger rod, which activates a mechanical switch to send a tangled rope signal, stopping the drum. This solution is limited by the drum's size and installation height, requiring custom-made drums and lacking versatility. It also has high manufacturing costs. Furthermore, the mechanical switch is affected by temperature; it may not be at zero position in winter, and it cannot respond promptly after tangling occurs. We urgently need to introduce and strengthen technical means to effectively reduce or even solve these problems. Utility Model Content

[0071] Example 7

[0072] Based on any one of Embodiments 5 to 6, in this embodiment, the bracket 5 is provided with a plurality of through holes through which the lower ends of the plurality of spring seats 3 pass.

[0073] The scheme has a simple structure and reasonable design. Multiple spring seats 3 are inserted into multiple through holes, which makes assembly convenient and facilitates the downward movement of the trigger rod 1 under the action of the wire rope.

[0074] It should be noted that since both the bracket 5 and the trigger rod 1 are in a horizontal state during testing, the lower ends of the multiple spring seats 3 can slide up and down through the multiple through holes respectively, without slipping off the bracket 5.

[0075] During the transportation or carrying of the testing device, if multiple spring seats 3 slip off from the bracket 5, the multiple spring seats 3 can be inserted into the multiple through holes when in use.

[0087] In addition, the four bases 6 mentioned above are preferably rectangular, which increases the contact area of ​​the device and improves its stability.

[0088] Furthermore, square tubes are preferably used on both sides and the middle of the open ends of frame one and frame two. The overall height of the frame can be adjusted by using the internal threads of the holes at the four corners of the bracket to cooperate with the threaded base. The operation is convenient. It should be noted that the surface of the sleeved square tubes should be perforated. After the steel tubes are sleeved together, they should be fixed with thread to prevent the frame from moving.

[0089] The working principle of this utility model is as follows:

[0090] During the inspection, when the wire rope on the drum becomes tangled, the wire rope will contact the trigger rod 1 and press down the trigger rod 1. Then, during the pressing down process, the trigger rod 1 drives multiple spring seats 3 to trigger multiple photoelectric switches 7 to confirm that the tangled situation has occurred. The multiple photoelectric switches 7 send the corresponding signals to the controller, and the controller controls the drum to stop operation.

[0091] When the wire rope on the drum becomes tangled, it will collide with the trigger rod of the device, overcome the spring force and descend, with the lower part of the spring seat approaching the photoelectric switch.

[0092] During this process, once the photoelectric switch is triggered, it will immediately send a command to the controller of the quay crane equipment via communication signal, thereby realizing the prohibition function of the equipment drum.

[0093] This utility model has a simple and reasonable structure with adjustable height and length, making it suitable for detecting tangled wire ropes on drums of different sizes and installation heights. It solves the problem that traditional tangled wire rope detection devices can only be customized according to the drum size, and cannot be mass-produced or universally applicable. It has the advantages of good practical effect, saving labor costs, and safety and reliability, providing a safe and efficient solution for the problem of tangled wire rope detection on drums.

[0094] It should be noted that all electronic components involved in this utility model adopt existing technology, and all the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is existing technology.
