Description

Technical Field

[0001] This utility model relates to the field of drag chain cable technology, and more specifically, to a high-temperature resistant drag chain cable. Background Technology

[0002] In the mechanical field, drag chain cables, as key components used to protect and guide cables within drag chain systems, directly affect the stable operation of equipment. Existing drag chain cables often suffer from problems in practical applications, such as inconvenience in cable separation and organization, and poor fixation. For example, cables of different specifications are difficult to separate effectively, easily leading to tangling and wear. Simultaneously, the drag chain structure lacks flexibility in adjusting the clamping force of the cables, making it difficult to adapt to cables of different diameters. Furthermore, the installation and disassembly of some drag chain fixing plates are cumbersome, hindering later maintenance and adjustments. In addition, the positioning and fixing structures of traditional drag chain cables lack targeted design, and during long-term use, factors such as vibration and friction may cause the cables to loosen, affecting the normal operation of the equipment. These problems all limit the applicability and reliability of drag chain cables under complex working conditions. Utility Model Content

[0006] In a preferred embodiment of this utility model, grooves are symmetrically provided at both ends of the second drag chain fixing plate, springs are symmetrically fixedly installed on one side of the inner wall of the groove, and a plug is fixedly installed at one end of the spring. Slots matching the plugs are provided on the relatively close side of the two drag chain outer plates, and the plugs are slidably connected to the inner wall of the groove.

[0007] In the preferred embodiment of this utility model, a plurality of first drag chain fixing plates and a plurality of second drag chain fixing plates correspond one-to-one.

[0008] In a preferred embodiment of this utility model, a push block is fixedly installed at the top of the insert block, and the top of the push block slides through the second drag chain fixing plate and extends to the outside. The second drag chain fixing plate is provided with a sliding hole that matches the push block. A sealing plate is fixedly installed on one side of the push block, and a sealing groove that matches the sealing plate is provided on the inner wall of the sliding hole.

[0009] In a preferred embodiment of this utility model, the top of the first pad is provided with an arc-shaped groove that matches the cable body in number. The first pad is fixedly connected to the positioning frame by bolts. The first pad can be replaced as needed. The cable body is composed of a protective layer, a flame-retardant layer, a high-temperature resistant metal layer, a shielding layer, an insulation layer, a wire core, and filler.

[0010] In a preferred embodiment of this utility model, the bottom end of the second card pad is provided with a plurality of arc-shaped card grooves, the two ends of the second card pad are symmetrically fixedly installed with second sliders, the inner walls of the positioning frame are provided with limiting grooves matching the second sliders, the inner walls of the limiting grooves are fixedly installed with guide rods, the second sliders are slidably installed on the guide rods, and the two ends of the arc-shaped card grooves are arc-shaped.

[0011] In a preferred embodiment of this utility model, the adjusting assembly includes a bidirectional threaded rod, a support rod, and a turntable.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-3 The present invention provides a technical solution: a high-temperature resistant drag chain cable, comprising a drag chain outer side plate 110 and a positioning frame 120. The drag chain outer side plate 110 is symmetrically fixed between two positioning frames 120. Multiple first drag chain fixing plates 111 and multiple second drag chain fixing plates 112 are fixedly installed between the two drag chain outer side plates 110. Multiple partitions 113 are slidably installed at the bottom of the second drag chain fixing plates 112. Multiple positioning grooves matching the partitions 113 are provided on the first drag chain fixing plates 111. A first retaining pad 121 is fixedly installed at the bottom of the inner wall of the positioning frame 120. A second retaining pad 122 is slidably installed between the two sides of the positioning frame 120. An adjustment component is installed at the top of the second retaining pad 122.

[0023] In some specific implementations, a first groove is provided at the bottom of the second cable chain fixing plate 112, a guide rod 114 is fixedly installed between the two sides of the inner wall of the first groove, and a first slider 115 is fixedly installed at the top of the partition 113. The first slider 115 is slidably mounted on the guide rod 114 and slidably connected to the inner wall of the first groove. This structure not only guides the movement of the first slider 115 through the guide rod 114 to ensure the stability of the partition 113 during sliding, but also further restricts the movement trajectory of the partition 113 by utilizing the sliding cooperation between the first slider 115 and the first groove, so that the partition 113 can accurately match the positioning groove on the first cable chain fixing plate 111, improving the accuracy and reliability of cable separation.

[0024] Please see Figure 3 and Figure 4The second cable chain fixing plate 112 has symmetrically arranged grooves at both ends. Springs 130 are symmetrically fixed to one side of the inner wall of the grooves, and insert blocks 131 are fixedly installed at one end of the springs 130. The two outer cable chain plates 110 have slots 132 that match the insert blocks 131 on their relatively close sides. The insert blocks 131 are slidably connected to the inner wall of the grooves. This structure enables the second cable chain fixing plate 112 to be quickly snapped and fixed to the outer cable chain plates 110. The elastic force of the springs 130 ensures the tightness of the connection between the insert blocks 131 and the slots 132. At the same time, the slidably connected insert blocks 131 are easy to move flexibly during installation and disassembly, simplifying the installation and disassembly process of the second cable chain fixing plate 112 and improving maintenance efficiency.

[0025] In some specific implementations, multiple first cable chain fixing plates 111 and multiple second cable chain fixing plates 112 correspond one-to-one. This makes the cable separation layout within the cable chain more regular, avoids cable separation chaos caused by misalignment of the fixing plates, and improves the overall coordination and stability of the cable chain structure.

[0026] In some specific implementations, a push block 133 is fixedly installed on the top of the insert block 131. The top of the push block 133 slides through the second cable chain fixing plate 112 and extends to the outside. The second cable chain fixing plate 112 is provided with a sliding hole that matches the push block 133. A sealing plate 134 is fixedly installed on one side of the push block 133. A sealing groove that matches the sealing plate 134 is provided on the inner wall of the sliding hole. The push block 133 allows the user to push the insert block 131 to compress the spring 130, quickly releasing the engagement between the second cable chain fixing plate 112 and the outer cable chain plate 110, facilitating disassembly. The cooperation between the sealing plate 134 and the sealing groove prevents dust, moisture, and other impurities from entering the groove through the sliding hole, avoiding the failure of the spring 130 and the insert block 131 due to impurities, and extending the service life of the components.

[0027] Please see Figure 5 and Figure 6The first clamping pad 121 has an arc-shaped groove at its top that matches the cable body 100 in number. The first clamping pad 121 is fixedly connected to the positioning frame 120 by bolts 123. The first clamping pad 121 can be replaced as needed. This ensures effective cable fixation by replacing the appropriate first clamping pad 121 when the cable specifications change, improving the versatility and flexibility of the drag chain cable. The second clamping pad 122 has multiple arc-shaped grooves at its bottom. The second sliders 124 are symmetrically fixedly installed at both ends of the second clamping pad 122. The inner walls of the positioning frame 120 have limiting grooves that match the second sliders 124. Guide rods 125 are fixedly installed on the inner walls of the limiting grooves. The second sliders 124 are slidably installed on the guide rods 125. The two ends of the arc-shaped grooves are arc-shaped. The multiple arc-shaped grooves at the bottom of the second pad 122 can fit against the cable surface and limit the top of the cable; the second sliders 124 at both ends slide on the guide rods 125 in the limiting groove of the positioning frame 120, ensuring the stability of the second pad 122 when moving up and down and avoiding deviation; the arc-shaped design at both ends of the arc-shaped groove can reduce friction and scratches on the cable surface, protect the cable insulation layer, and extend the service life of the cable.

[0028] In some specific implementations, the adjustment assembly includes a bidirectional threaded rod 140, a support rod 141, and a turntable 142. A strip groove is provided at the top of the inner wall of the positioning frame 120. The bidirectional threaded rod 140 is rotatably mounted between the two sides of the inner wall of the strip groove. Support blocks 143 are symmetrically threaded onto the bidirectional threaded rod 140. The bottom end of the support block 143 is hinged to the support rod 141. The bottom ends of the two support rods 141 are symmetrically hinged to the top of the second retaining pad 122. A rotating shaft is fixedly mounted at one end of the bidirectional threaded rod 140, and the other end of the rotating shaft passes through the positioning frame 120 and is fixedly mounted on the turntable 142. The support block 143 is slidably connected to the inner wall of the strip groove. A circular groove matching the turntable 142 is provided on one side of the positioning frame 120, and the turntable 142 is slidably connected to the inner wall of the circular groove. A slot is provided on one side of the turntable 142. This design allows users to easily rotate the turntable 142 using tools, making operation convenient. The overall structure improves the compatibility and fixing effect of the drag chain cable for cables of different specifications.

[0029] Working principle: First, the outer cable chain plates 110 are symmetrically fixed between two positioning frames 120. Multiple first cable chain fixing plates 111 and multiple second cable chain fixing plates 112 are fixedly installed between the two outer cable chain plates 110, corresponding one-to-one. Multiple partitions 113 slidably installed at the bottom of the second cable chain fixing plates 112 cooperate with the positioning grooves on the first cable chain fixing plates 111 to separate and organize the cable body 100. The partitions 113 slide on guide rods 114 in the first sliding groove at the bottom of the second cable chain fixing plates 112 via a first slider 115 at their top, achieving position adjustment. Springs 130 in the grooves at both ends of the second cable chain fixing plates 112 push inserts 131 into slots 132 in the outer cable chain plates 110, completing the locking and fixing. Pushing blocks 133 can drive the inserts 131 to compress the springs 130 and disengage them from the slots 132, facilitating disassembly. Furthermore, the sealing plate 134 on one side of the push block 133 cooperates with the sealing groove in the sliding hole to achieve sealing; the first pad 121 at the bottom of the inner wall of the positioning frame 120 is fixed by bolts 123, and its top arc groove can limit the bottom of the cable body 100, and the first pad 121 can be replaced as needed; the second pad 122, which is slidably installed between the two sides of the positioning frame 120, slides on the guide rod 125 in the limiting groove through the second sliders 124 at both ends, and its bottom arc groove limits the top of the cable, and the arc groove is set at both ends to avoid scratching the cable; the turntable 142 of the rotating adjustment component drives the bidirectional threaded rod 140 to rotate, so that the two support blocks 143 in the strip groove slide symmetrically along the bidirectional threaded rod 140, and the support blocks 143 push the second pad 122 up and down through the support rod 141, thereby adjusting the clamping force on the cable and achieving stable fixing of cables of different specifications.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
