Description

Technical Field

[0001] This application relates to the technical field of electromagnetic induction heating, and more specifically, to a high-frequency cable drag chain. Background Technology

[0002] Drag chain cables are highly flexible special cables that can move back and forth with a drag chain without being easily worn. They are also commonly known as drag cables or tank chain cables. In situations where equipment units need to move back and forth, in order to prevent cables from getting tangled, worn, pulled out, snagged, or scattered, cables are often placed in cable drag chains to protect them, and the cables can also move back and forth with the drag chain.

[0003] Conventional cable chains are typically made of metal or plastic. For movable, high-frequency, high-current cables, the high-frequency current generates heat in the adjacent metal circuits, posing a significant risk to the cable insulation. All-plastic cable chains are unsuitable for heavy-duty and long-distance applications. Therefore, there is a need to develop a cable chain structure that boasts high load-bearing capacity and does not cause overheating in the metal components. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-frequency cable drag chain to address the above-mentioned problems.

[0005] The embodiments of this application are implemented as follows:

[0006] This application provides a high-frequency cable drag chain, characterized in that it includes two side chain plates, support rods, and reinforcing devices. The two side chain plates are composed of alternating hinged single chain plates and double chain plates. The support rods are arranged in three layers: upper, middle, and lower. The two ends of the support rods are respectively screwed to the two side chain plates. The reinforcing devices include an interlayer reinforcing mechanism and a longitudinal reinforcing mechanism. Both the interlayer reinforcing mechanism and the longitudinal reinforcing mechanism are evenly spaced along the axial direction of the support rods. The interlayer reinforcing mechanism is vertically arranged and engages the upper, middle, and lower support rods. The longitudinal reinforcing mechanism is horizontally arranged and engages the upper and lower support rods.

The slots of the two interlayer snap-fit ​​plates are stacked on the left and right respectively and connected and fastened through the connecting holes.

[0008] In some optional implementations, the longitudinal reinforcing mechanism includes two longitudinal snap-fit ​​plates arranged symmetrically at the top and bottom.

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0031] like Figure 1 The present invention provides a high-frequency cable drag chain, including two side chain plates, support rods 1, and reinforcing devices. The two side chain plates are composed of alternating hinged single chain plates 2 and double chain plates 3. The support rods are arranged in three layers: upper, middle, and lower. The two ends of the support rods are screwed to the two side chain plates respectively. The reinforcing devices include an interlayer reinforcing mechanism 4 and a longitudinal reinforcing mechanism 5. Both the interlayer reinforcing mechanism and the longitudinal reinforcing mechanism are evenly spaced along the axial direction of the support rods. The interlayer reinforcing mechanism is vertically arranged and clamps the upper, middle, and lower support rods. The longitudinal reinforcing mechanism is horizontally arranged and clamps the upper and lower support rods.

[0032] The interlayer reinforcement mechanism includes two interlayer snap-fit ​​plates 6 arranged symmetrically on the left and right. Three U-shaped slots 7 are provided on one side of the interlayer snap-fit ​​plate, and three connecting holes 8 are provided at intervals along the central axis of the interlayer snap-fit ​​plate. The slots of the two interlayer snap-fit ​​plates are correspondingly stacked on the left and right, and are connected and fastened through the connecting holes.

[0033] The longitudinal reinforcement mechanism includes two longitudinal snap-fit ​​plates 9 arranged symmetrically on the top and bottom. The bottom edge of the longitudinal snap-fit ​​plates is provided with three U-shaped slots at intervals. The two ends of the longitudinal snap-fit ​​plates are respectively provided with connecting holes. The slots of the two longitudinal snap-fit ​​plates are correspondingly stacked on top of each other and connected and fastened through the connecting holes.

[0034] The double-chain plate has a clamping partition 10 in the middle. The single-chain plate, double-chain plate and clamping partition are made of austenitic stainless steel.

[0035] The support rods are made of plastic or austenitic stainless steel. Plastic support rods are installed in one of the three layers of support rods (top, middle, and bottom), while the remaining support rods are made of austenitic stainless steel. This ensures the overall structural strength of the cable chain while preventing eddy current heating in the metal circuit of the high-frequency, high-current cable.

[0036] Two spacer plates 11 are provided on each side of the interlayer reinforcement mechanism. Support holes are provided on the spacer plates at intervals, and support rods are inserted through them. After the spacer plates are installed, the cable space is divided, and the interlayer reinforcement is achieved by combining them with the interlayer reinforcement mechanism.

[0037] Three upper and three lower support rods are horizontally spaced, while one middle support rod is installed. Each support rod is fitted with a sleeve 12 made of ordinary plastic to reduce wear on the cable insulation during cable chain operation.

[0038] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
