Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, and particularly relates to a longitudinal wrapping device for a water-blocking tape of a cable conductor. Background Art

[0002] At present, during the laying of high-voltage cables, in order to prevent water and moisture from entering the cable interior, a water-blocking tape is usually longitudinally wrapped between the insulating core and the metal sheath to improve the water-blocking ability of the cable.

[0003] However, the existing longitudinal wrapping devices for water-blocking tapes have complex structures, high maintenance costs, and fixed structures. They cannot adjust their own heights according to the inlet position of the stranding equipment and the height of the insulating core, so they cannot well wrap the water-blocking tape around the outside of the insulating core, affecting the wrapping effect and reducing the water-blocking ability. In addition, when replacing the water-blocking tape reel, the disassembly and assembly are inconvenient and the efficiency is low.

[0004] Therefore, there is an urgent need for a longitudinal wrapping device for a water-blocking tape of a cable conductor. Summary of the Utility Model

[0005] In view of the above-mentioned defects existing in the prior art, the utility model provides a longitudinal wrapping device for a water-blocking tape of a cable conductor, which includes a base, a telescopic support rod, and a unwinding mechanism. The telescopic support rod is located above the base. The telescopic support rod includes an outer telescopic rod, an inner telescopic rod, and a positioning insertion rod. The bottom of the outer telescopic rod is fixed on the base. The inner telescopic rod is inserted into the interior of the outer telescopic rod, and corresponding positioning holes are provided on the inner telescopic rod and the outer telescopic rod. The positioning insertion rod is inserted into the positioning holes of the inner telescopic rod and the outer telescopic rod.

[0006] The unwinding mechanism is located above the telescopic support rod. The unwinding mechanism includes a disc assembly and a fixing assembly. The disc assembly includes a first disc and a second disc arranged up and down, and the diameter of the first disc is not greater than that of the second disc. The first disc can play a certain limiting role on the water-blocking tape reel, preventing it from shaking randomly during unwinding. Concentric upper pads and circular grooves are respectively provided on the top surface and the bottom surface of the first disc, and a first through hole penetrating up and down is opened at the centers of the upper pad, the first disc, and the circular groove. The second disc mainly plays a supporting role for the water-blocking tape reel. Concentric shaft tubes and lower pads are respectively provided on the top surface and the bottom surface of the second disc, and a second through hole penetrating up and down is opened at the centers of the shaft tube, the second disc, and the lower pad. The top end of the shaft tube is matched with the circular groove. The fixing assembly includes a fixing plate, a fixing rod, and a fastening sleeve. The fixing plate is horizontally fixed on the top of the inner telescopic rod. The fixing rod is obliquely fixed on the fixing plate, and the fixing rod sequentially penetrates through the second through hole of the second disc and the first through hole of the first disc from bottom to top. A lower support plate is vertically fixed on the outside of the lower end of the fixing rod. The fastening sleeve is threadedly connected to the top end of the fixing rod, and an upper pressing plate is vertically fixed on the outside of the bottom end of the fastening sleeve.

[0007] Optionally, the base consists of two channel steels, and the two channel steels are vertically and fixedly connected.

[0008] Optionally, the angle between the fixing rod and the horizontal plane is 40 - 50°.

[0009] Specifically, since the fixing rod is inclined, the disc assembly and the water-blocking tape reel are also in an inclined state, so that the water-blocking tape can better cooperate with the insulated wire core for wrapping, improving the wrapping effect.

[0010] Optionally, both the first through hole and the second through hole match the outer shape of the fixing rod.

[0011] Optionally, a handle is provided on the fastening sleeve.

[0012] Specifically, the handle facilitates screwing the fastening sleeve.

[0013] The present utility model further includes other components that can enable a water-blocking tape longitudinal wrapping device for a cable conductor to be used normally, which are all conventional technical means in the art. In addition, the devices or components not defined in the present utility model all adopt conventional technical means in the art.

[0014] The working principle of the present utility model is as follows: First, the second disc is sleeved on the fixing rod, and the lower cushion block of the second disc abuts against the lower support plate of the fixing rod. Then, the water-blocking tape reel is sleeved on the shaft cylinder of the second disc, and the inner diameter of the central hole of the water-blocking tape reel is larger than the outer diameter of the shaft cylinder of the second disc. Next, the first disc is sleeved on the fixing rod, and the top end of the shaft cylinder of the second disc is inserted into the circular groove of the first disc in a matching manner, and the width of the water-blocking tape reel is smaller than the distance between the two discs. After that, the fastening sleeve is installed at the top end of the fixing rod, and the upper pressing plate abuts against the upper cushion block of the first disc, thereby fixing the first disc and the second disc. Subsequently, according to the incoming line position of the on-site stranding equipment and the height of the insulated wire core, the height of the disc assembly is adjusted, and the operation steps are as follows: Adjust the length of the inner telescopic rod extending out of the outer telescopic rod, and fix it with the positioning insertion rod after the adjustment is completed; finally, the water-blocking tape is wrapped around the outside of the insulated wire core through the stranding equipment. When it is necessary to replace the water-blocking tape reel, only need to unscrew the fastening sleeve and remove the first disc, then the water-blocking tape reel can be replaced.

[0015] The beneficial effects of the present utility model are as follows: The structure is simple, and the maintenance cost is low; the height of the water-blocking tape reel can be adjusted through the telescopic support rod, and the water-blocking tape reel can be tilted at a certain angle through the inclined fixing rod, so that it can better cooperate with the insulated wire core for wrapping, improving the wrapping effect and the water-blocking ability; in addition, through the disc assembly, it is convenient to replace the water-blocking tape reel, the disassembly and assembly are convenient, and the efficiency is high.
