Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a highly flexible drag chain cable. Background Technology

[0002] Drag chain cable is a highly flexible special cable that can move back and forth with a drag chain without being easily worn. It is also commonly known as drag cable or tank chain cable.

[0003] When using cable carriers, cables are inserted into the cable carrier from one end and exit from the other. Typically, there are multiple cables in a cable carrier, which are bundled together with cable ties. This reduces the heat dissipation surface area of ​​the cables in the cable carrier, thus lowering their heat dissipation efficiency. Furthermore, the cables in the cable carrier need to be pulled out of the cable carrier before they can be inspected and maintained. When pulling the cables out of the cable carrier, the connection between the cables and the equipment needs to be disconnected, making the inspection and maintenance of cable carriers difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a highly flexible drag chain cable that allows the cables in the drag chain to be arranged in an orderly manner, and the cables in the drag chain can be taken out of the drag chain without disconnecting from the equipment, which facilitates the inspection and maintenance of the cables.

[0005] To achieve the above objectives, a highly flexible drag chain cable is provided, comprising a moving end, several chain links, and a fixed end. The chain links are arranged in an orderly manner and rotatably connected in the form of a chain. The moving end and the fixed end are respectively installed at both ends of the chain composed of the chain links. A support cover is provided at the upper end of each chain link, and a connecting rod is fixedly connected to the lower end of the support cover, extending downward into the chain link. A wire-separating clamping mechanism is fixedly connected to the lower end of the connecting rod. Several cable bodies are provided on the side of the moving end away from the chain links, and the cable bodies pass through the moving end sequentially. The cable carrier comprises an end, several chain links, and a fixed end. The cable body within each chain link passes through a cable clamping mechanism. Each chain link consists of an upper baffle, chain plates, a lower baffle, and a rotating shaft. The chain plates are fixedly connected to the upper end of the lower baffle and are located at both ends of the lower baffle. The rotating shaft is located on the surface of the chain plates, and adjacent chain links are rotatably connected to the chain plates via the rotating shaft. The upper baffle is fixedly connected to the upper ends of two chain plates, and bolts are fixedly connected to the upper end of the upper baffle. Guide holes are provided at the upper end of the upper baffle, located on both sides of the bolts. This design allows the cables in the cable carrier to be arranged in an orderly manner, and the cables can be removed from the cable carrier without disconnecting from the equipment, facilitating cable inspection and maintenance.

[0006] According to the aforementioned highly flexible drag chain cable, the branch clamping mechanism comprises a clamping block, a fixing frame, a support plate, a knob, and a screw. The support plate is fixedly connected to the lower end of the connecting rod. The fixing frame has an L-shaped structure and is fixedly connected to the lower end of the support plate, with one side of the fixing frame and one side of the support plate on the same plane. The clamping block is disposed between the fixing frame and the support plate. Several semi-circular limiting strips are fixedly connected at equal intervals to the lower end of the support plate. The upper end of the clamping block has a semi-circular protrusion corresponding to the limiting strips. The cable body passes between the fixing frame and the support plate, and the surface of the cable body is clamped by two adjacent limiting strips on the support plate and the clamping block. The screw is rotatably connected to the lower middle part of the clamping block, and the lower end of the screw passes through the fixing frame and is threadedly connected to the fixing frame. The knob is fixedly connected to the lower end of the screw. A sliding groove is opened on the side end of the fixing frame, and a limiting slider is slidably connected to the side end of the fixing frame. One end of the limiting slider passes through the sliding groove and is fixedly connected to the clamping block. The knob rotates the screw, and the screw, in conjunction with the fixing frame, lifts the clamping block upwards, allowing the clamping block to engage with the support plate to fix the cable. The limiting strips limit the cable's position, ensuring that the cables in the cable chain are arranged in an orderly manner.

[0007] According to the aforementioned highly flexible drag chain cable, the cable body comprises an outer sheath, a shielding layer, a filling layer, an insulation layer, a tensile rope, and conductors. The insulation layer covers the outer surface of the conductors, and multiple conductors are provided. The tensile rope is located between the multiple conductors, and the multiple conductors covered with the insulation layer are twisted together around the tensile rope. The filling layer covers the outside of the insulation layer, and several conductors are located within the filling layer. The shielding layer covers the outside of the filling layer, and the outer sheath covers the outside of the shielding layer. The cable body composed of the outer sheath, shielding layer, filling layer, insulation layer, tensile rope, and conductors has good flexibility, abrasion resistance, and tensile strength.

[0008] According to the aforementioned highly flexible drag chain cable, a nut is provided at the upper end of the support cover, and the support cover is located at the upper end of two upper baffles. A bolt passes through the support cover and is threadedly connected to the nut. The engagement of the nut and bolt fixes the support cover to the upper baffle of the chain link, thus fixing the cable clamping mechanism within the drag chain composed of the chain links.

[0009] According to the aforementioned highly flexible drag chain cable, a guide rod with a matching guide hole is installed at the lower end of the support cover. The matching of the guide hole and the guide rod positions the support cover on the chain link.

[0010] According to the aforementioned highly flexible drag chain cable, a flexible belt is fixedly connected to the upper end of the support cover, and two adjacent support covers are connected by the flexible belt. The flexible belt connects the support covers installed on several chain links to each other, facilitating the removal of the branch clamping mechanism in the drag chain.

[0011] According to the aforementioned highly flexible drag chain cable, the limiting strip is made of rubber and is fixed to the lower end of the support plate using adhesive. The rubber limiting strip prevents excessive pressure from being applied to the outer surface of the cable body when limiting its movement, thus avoiding damage to the cable body.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. The screw pushes the clamping block to rise, so that the clamping block and the limiting strip at the lower end of the support plate limit and clamp the cable. The branch clamping mechanism in several chain links cooperates to arrange the cable in an orderly manner in the drag chain, which is convenient for maintenance.

[0014] 2. The flexible belt connects the cable clamping mechanism in the cable carrier into a whole, making it easy to pull out the cable in the cable carrier in one go, which is convenient for inspection and maintenance.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
