Description

Technical Field

[0001] This utility model relates to the field of power transmission and distribution network cable line duct technology, and in particular to a flared duct terminal joint for reducing cable laying stress. Background Technology

[0002] During cable duct laying, a working well is required at regular intervals for cable laying and deployment. Currently, most construction methods involve directly laying the cable protection pipe into the inner wall of the working well. This causes laying stress at the inlet and outlet of the protection pipe when the cable turns or is suspended within the working well, resulting in significant damage to the cable itself. Therefore, we propose a flared duct terminal joint to reduce cable laying stress and address the aforementioned problems. Summary of the Invention

[0003] This utility model proposes a flared pipe terminal joint for reducing cable laying stress, in order to solve the problems mentioned in the background art.

The auxiliary component includes several sets of rotatable upper rollers, which are equidistantly arranged above the interior of the pipe terminal connector body. A set of rotatable lower rollers is installed below each of the several sets of upper rollers, which are also located below the interior of the pipe terminal connector body. Each end of the several sets of upper and lower rollers is equipped with a set of positioning components for positioning the upper and lower rollers.

[0005] Preferably, the positioning component includes two sets of rotating shafts, which are rotatably connected to the two ends of the upper roller or the lower roller, respectively. The other end of each set of rotating shafts is fixedly connected to a set of mounting blocks. The lower ends of each set of mounting blocks are fixedly connected to both sides of the upper end of the mounting plate. The other end of the mounting plate is fixedly connected to a sponge block, and the other end of the sponge block is fixedly connected to a positioning plate. The other end of the positioning plate is fixedly connected to the inner wall of the pipe terminal connector body.

[0006] Preferably, a set of protective sleeves is fixedly fitted on the outer side of each of the several sets of upper and lower rollers.

[0007] Preferably, the protective sleeve includes a reinforcing layer, a fireproof layer, a heat insulation layer, an insulating layer, and a sliding layer.

[0008] Preferably, the fireproof layer is fixedly sleeved on the outside of the reinforcing layer, the heat insulation layer is fixedly sleeved on the outside of the fireproof layer, the insulating layer is fixedly sleeved on the outside of the heat insulation layer, and the sliding layer is fixedly sleeved on the outside of the insulating layer.

[0011] The beneficial effects of this utility model are as follows: This flared duct terminal joint, designed to reduce cable laying stress, features a flared opening at one end of the joint body to reduce cable laying stress. Simultaneously, auxiliary components, including several sets of upper and lower rollers, reduce friction between the cable's upper and lower ends and the inner wall of the duct terminal joint body, improving laying efficiency and preventing cable damage due to friction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-8 As shown, a flared duct terminal connector for reducing cable laying stress includes a duct terminal connector body 1, one end of which is fixedly connected to a flared opening, and the interior of the duct terminal connector body 1 is provided with auxiliary components for improving cable laying speed. The auxiliary components include several sets of rotatable upper rollers 2, which are equidistantly arranged above the interior of the pipe terminal connector body 1. A set of rotatable lower rollers 3 is installed below each set of upper rollers 2, which are also located below the interior of the pipe terminal connector body 1. A set of positioning components for positioning the upper rollers 2 and lower rollers 3 is installed at both ends of each set of upper rollers 2 and lower rollers 3.

[0023] The positioning component includes two sets of rotating shafts 4, which are rotatably connected to the two ends of the upper roller 2 or the lower roller 3, respectively. A set of mounting blocks 5 is fixedly connected to the other end of each set of rotating shafts 4. The lower ends of the mounting blocks 5 are fixedly connected to both sides of the upper end of the mounting plate 6. A sponge block plate 7 is fixedly connected to the other end of the mounting plate 6, and a positioning plate 8 is fixedly connected to the other end of the sponge block plate 7. The other end of the positioning plate 8 is fixedly connected to the inner wall of the pipe terminal connector body 1. A set of protective sleeves 9 is fixedly fitted onto the outer sides of several sets of upper rollers 2 and lower rollers 3.

[0024] In this embodiment, the cable is threaded through the interior of the inner duct terminal connector body 1. During the laying process, the upper and lower ends of the cable are guided by several sets of upper rollers 2 and lower rollers 3, reducing the friction between the upper and lower ends of the cable and the inner wall of the duct terminal connector body 1. This improves the efficiency of cable laying inside the duct terminal connector body 1 and avoids damage to the cable due to friction with the duct terminal connector body 1, thus extending the cable's service life. By opening a funnel-shaped opening at one end of the duct terminal connector body 1, the laying stress of the cable can be reduced, achieving the purpose of reducing laying stress. At the same time, by setting auxiliary components, the several sets of upper rollers 2 and lower rollers 3 can reduce the friction between the upper and lower ends of the cable and the inner wall of the duct terminal connector body 1, improving the efficiency of cable laying inside the duct terminal connector body 1 and avoiding damage to the cable due to friction with the duct terminal connector body 1, thus extending the cable's service life.

[0025] Furthermore, the protective sleeve 9 includes a reinforcing layer 10, a fireproof layer 11, a heat insulation layer 12, an insulating layer 13, and a sliding layer 14. The fireproof layer 11 is fixedly fitted onto the outside of the reinforcing layer 10, the heat insulation layer 12 is fixedly fitted onto the outside of the fireproof layer 11, the insulating layer 13 is fixedly fitted onto the outside of the heat insulation layer 12, and the sliding layer 14 is fixedly fitted onto the outside of the insulating layer 13. The thicknesses of the reinforcing layer 10, fireproof layer 11, heat insulation layer 12, insulating layer 13, and sliding layer 14 are equal. By providing the protective sleeve 9 composed of the reinforcing layer 10, fireproof layer 11, heat insulation layer 12, insulating layer 13, and sliding layer 14, several sets of upper rollers 2 and lower rollers 3 can be protected, thereby improving the working quality of the upper rollers 2 and lower rollers 3.

[0026] Furthermore, a set of positioning blocks 15 are fixedly connected to both ends of the positioning plate 8, and a set of positioning bolts 16 are fixedly installed on each of the two sets of positioning blocks 15. Several sets of positioning bolts 16 are threadedly connected to the inner wall of the pipe terminal connector body 1. By setting the positioning blocks 15 and positioning bolts 16, several sets of positioning plates 8 can be installed and fixed.
