[0002] In the metallurgical industry, magnetic disk cranes are magnetic load hanging devices for cranes, which are particularly suitable for lifting irregular metal heavy objects. In steel mills, the electromagnetic characteristics of magnetic disk cranes can be used to clean iron-containing materials on the ground and transport irregular steel billets.

[0003] During the actual use of the disk crane, the crane cable needs to be connected to the disk cable. The conventional connection method is to use an ordinary clamp for connection. However, during use, it is easy to have poor contact or disconnection after rotation force, and the current contacts the iron to produce sparks and burn the entire cable. At the same time, the electromagnetic force of the disk disappears and the irregular metal weights that are stuck fall off. This not only increases the frequency of reconnecting the crane cable and the disk cable, but also seriously affects production and poses a safety risk. Utility Model Content

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0031] like Figure 1-4 As shown, the utility model provides a disk hanging terminal rotary connector assembly for metallurgy, comprising a first connector 1 and a second connector 2.

[0032] like Figure 1 and 2As shown, the first connector 1 includes a first cable receiving portion 11 and a rotation insertion portion 12 extending coaxially with the first cable receiving portion 11. Figure 3 and Figure 4 As shown, the second connector 2 includes a rotation receiving portion 21 for receiving the rotation receiving portion 12, and a second cable receiving portion 22 extending coaxially with the rotation receiving portion 21. The rotation inserting portion 12 is rotationally engaged with the rotation receiving portion 21 within a predetermined range, and when the rotation inserting portion 12 is rotated out of the predetermined range relative to the rotation receiving portion 21 (it can be rotated clockwise or counterclockwise), the rotation inserting portion 12 is disconnected from the rotation receiving portion 21.

[0033] like Figure 1 and 2 As shown, the first cable receiving part 11 is a tubular structure having a first cavity 111, and includes an inner layer 112 and an outer layer 113. The inner layer 112 is a tubular structure with a circular cross section, and the outer layer 113 is a hexagonal tubular structure with a cross section external to the inner layer 112. A fixing member 115 that can be adjusted to extend into the first cavity 111 is provided on an outer side surface 114 of the outer layer 113, and is used to fix and connect the crane cable (not shown) and the disk hanging cable (not shown). In a preferred embodiment, the number of the fixing members 115 is two, and the fixing members 115 are screws. That is, the crane cable and the disk hanging cable are placed in the first cavity 111, and the crane cable and the disk hanging cable are fastened by tightening the fixing member 115 (screw), so that the crane cable and the disk hanging cable can be prevented from poor contact or disconnection.

[0034] like Figure 1 As shown, the rotating insert portion 12 of the first connector 1 has a solid cylindrical structure, the first end of the rotating insert portion 12 and one end of the first cable receiving portion 11 are integrally formed, and the second end of the rotating insert portion 12 is provided with an engaging protrusion 121 .

[0035] like Figure 3As shown, in a preferred embodiment, the rotation receiving portion 21 is a tubular structure having a second cavity 211, and the inner wall of the second cavity 211 is provided with a thread in the circumferential direction, and the thread includes a joint section AB segment screwed with the joint protrusion 121, and a disconnection section AD segment extending along one end of the joint section AB segment and a disconnection section BC segment extending along the other end of the joint section AB segment. The thread teeth 213 of the joint section AB segment of the thread have a height that enables the joint protrusion 121 to engage with the thread teeth 213 of the joint section AB segment, and the thread teeth 215 of the disconnection section AD segment of the thread and the thread teeth 214 of the disconnection section BC segment of the thread have a height that enables the joint protrusion 121 to be disconnected from the thread teeth 215 of the disconnection section AD segment and the thread teeth 214 of the disconnection section BC segment. It should be understood by those skilled in the art that the height of the thread teeth involved in this embodiment refers to the distance between the crest of the thread teeth and the inner wall of the second cavity 211. Among them, the thread teeth 215 of the disconnection section AD segment of the thread and the thread teeth 214 of the disconnection section BC segment of the thread have a gradually decreasing height. Those skilled in the art should also understand that, in the present embodiment, the predetermined range in which the rotating insertion part 12 and the rotating receiving part 21 can be rotationally engaged refers to the entire engaging part AB section, and when the engaging protrusion 121 of the rotating insertion part 12 rotates out of the engaging part AB section to the disconnecting part AD section or the disconnecting part BC section, the rotating insertion part 12 is disconnected from the rotating receiving part 21.

[0036] like Figure 3 As shown, the inner wall of the second cavity 211 is also provided with a guide groove MNO segment formed between the upper surface of the second cavity 211 and the threaded joint AB segment and the disconnection segments AD and BC segments in the circumferential direction for guiding the rotating insert 12 to screw into the second cavity 211, which includes an MN segment arc groove and an NO segment arc groove extending along it, and the radius of the MN segment arc groove is greater than the radius of the NO segment arc groove. Figure 4 As shown, in a preferred embodiment, the rotation receiving portion 21 is a tubular structure having a second cavity 211, and the inner wall of the second cavity 211 is provided with an arc-shaped step groove 216 having a predetermined length in the circumferential direction. When the engagement protrusion 121 is screwed into the step groove 216, the rotation insertion portion 12 is screwed into engagement with the rotation receiving portion 21; when the engagement protrusion 121 is rotated out of the step groove 216, the rotation insertion portion 12 is disconnected from the rotation receiving portion 21. Therefore, it should be understood by those skilled in the art that, in this embodiment, the predetermined range in which the rotation insertion portion 12 and the rotation receiving portion 21 can be screwed into engagement refers to the entire length range of the step groove 216.

[0037] like Figure 3 and 4As shown, the second cable receiving portion 22 has a solid cylindrical structure and is connected to the main cable. In a preferred embodiment, the first connector 1 and the second connector 1 are made of copper. The first connector 1 and the second connector 2 are respectively covered with insulating sleeves (not shown).

[0038] When using the first connector 1 and the second connector 2 of the utility model, the crane cable and the disk hanging cable are placed in the first cavity 111 of the first connector 1, and the crane cable and the disk hanging cable are fastened with the fixing member 115. Then, the rotating insertion part 12 of the first connector 1 is rotated into the second cavity 211 of the rotating receiving part 21 of the second connector 2, so that the engaging protrusion 121 of the rotating insertion part 12 engages with the engaging part AB section or the step groove 216 of the thread, thereby completing the rotational connection between the first connector 1 and the second connector 2 within a predetermined range.

[0039] When the disk is attached to an irregular metal weight, the rotation within the normal range will not cause the first connector 1 to rotate out of the predetermined range relative to the second connector 2, so the first connector 1 and the second connector 2 will not automatically fall off each other due to disconnection. If the first connector 1 and the second connector 2 are automatically disconnected, it indicates that there is a problem with the disk or some components during operation.

[0040] For example, when the metal object adsorbed by the disk is overloaded or the disk cannot adsorb the metal object at all, the first connector 1 rotates relative to the second connector 2 until it rotates out of the predetermined range and automatically disconnects and falls off from each other, causing the disk to short-circuit and generate sparks, thereby prompting the operator that the heavy metal object adsorbed by the disk has exceeded the disk's carrying capacity. At the same time, the disk loses its magnetism and all the adsorbed heavy metal objects have fallen off. After the operator turns off the power, he reconnects the first connector 1 and the second connector 2, and the disk can adsorb the heavy metal object again. Therefore, the first connector 1 and the second connector 2 automatically fall off, protecting the disk.

[0041] In addition, during the operation of the disk, the chain on the disk swings back and forth and rotates, causing the main cable to be seriously entangled, which will cause the first connector 1 to rotate relative to the second connector 2 or even rotate out of the predetermined range and automatically disconnect and fall off, thereby prompting the operator to check the cause of the first connector 1 and the second connector 2 falling off. At this time, the operator turns off the power supply, arranges the main cable, and then reconnects the first connector 1 and the second connector 2 to allow the disk to continue to work. In this case, the automatic falling off of the first connector 1 and the second connector 2 can prevent the main cable from being excessively entangled, causing friction and short circuit between each other, and causing the main cable to be burned.
