Description

Technical Field

[0001] The utility model relates to the technical field of cable construction equipment, in particular to a positioning device for power communication connection cables. Background Technique

[0002] Due to different construction conditions and requirements, communication optical cables will adopt different laying methods in different scenarios. Common laying methods include: direct burial, overhead, pipeline, underwater and indoor, etc. Among them, for direct burial, that is, directly burying, it means the laying method of directly burying the optical cable in the underground soil. Usually, in ordinary soil and hard soil, the optical cable needs to be buried more than 1.2 meters below the ground surface; when constructing a directly buried optical cable, it is necessary to first dig an optical cable trench that meets the requirements, then lay the buried optical cable at the bottom of the optical cable trench, and then backfill the soil.

[0003] When using the direct burial method to bury power communication cables, although the operation is simple and the construction cost is low, it also has relatively large defects. Since the cable is directly in contact with the soil, there is a lack of effective positioning measures for the outside of the cable. That is, due to the different hardness of the soil in each area, once it rains heavily, as the rainwater infiltrates, the hardness of the soil around the cable is reduced, resulting in soil flow. In this way, it is easy to cause the cable to shift and the cable to be damaged due to stress.

[0004] Therefore, in view of the above problems, the present technical solution proposes a positioning device for power communication connection cables. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning device for power communication connection cables to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A positioning device for a power communication connection cable, including a positioning clamp. The positioning clamp includes two sets of semi-circular clamping rings. One side of the clamping rings is rotatably connected through a swing shaft I, and a fastening member is provided on the opposite side. The swing clamping rings are opened and closed to be sleeved on the communication cable, and then fixed on the communication cable through the fastening member. A plurality of threaded hole grooves are evenly opened on the outer circumferential side wall of the clamping ring along the axial direction. A plurality of groups of limiting cone rods distributed along the radial direction of the communication cable are detachably installed inside the threaded hole grooves. A plurality of groups of swing positioning members are evenly arranged on the outer wall of the limiting cone rod. By arranging a plurality of groups of positioning clamps to be sleeved on the communication cable at intervals, when the communication cable is directly buried, the limiting cone rods are directly inserted into the buried soil for positioning. At the same time, under the action of the swing positioning members, the insertion force of the limiting cone rods into the soil is increased. When the soil around the positioning clamp is stressed and locally displaced, generating a thrust on the positioning clamp and the communication cable, the swing positioning members are stressed to expand the contact area with the soil, thereby increasing the reaction thrust of the positioning clamp relative to the soil displacement, so as to improve the positioning effect of the communication cable and enhance the protection strength of the communication cable.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: By sleeving a plurality of groups of positioning clamps on the communication cable at intervals, while using the friction cushion strips inside the positioning clamps for reinforcement, it is convenient for the communication cable to dissipate heat inside. At the same time, a plurality of groups of swing positioning members are evenly arranged on the outer side of the positioning clamp. By using the thrust and reaction thrust between the swing positioning members and the soil, the positioning strength of the positioning clamp on the communication cable is increased, and the damage caused by the change of the position of the communication cable due to the soil displacement caused by water flow is reduced.

[0016] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0017] Please refer to Figure 1 - Figure 2, A positioning device for a power communication connection cable, including a positioning clamp 11. The positioning clamp 11 includes two sets of semicircular clamping rings. One opposite side of the clamping rings is rotatably connected through a swing shaft I 12, and a fastener is provided on the other opposite side. The swing clamping rings are opened and closed to be sleeved on the communication cable 10, and then fixed on the communication cable 10 through the fastener. A plurality of threaded hole grooves 16 are evenly arranged along the axial direction on the outer circumferential side wall of the clamping ring. A plurality of groups of limiting cone rods 20 distributed along the radial direction of the communication cable 10 are detachably installed inside the threaded hole grooves 16. A plurality of groups of swing positioning members are evenly arranged on the outer wall of the limiting cone rod 20. By arranging a plurality of groups of positioning clamps 11 to be sleeved on the communication cable 10 at intervals, when the communication cable 10 is directly buried, the limiting cone rods 20 are directly inserted and positioned into the buried soil. At the same time, under the action of the swing positioning members, the insertion force of the limiting cone rods 20 into the soil is increased. When the soil around the positioning clamp 11 is stressed and locally displaced, generating a thrust on the positioning clamp 11 and the communication cable 10, the swing positioning members are stressed to expand the contact area with the soil, thereby increasing the reaction thrust of the positioning clamp 11 relative to the soil displacement, so as to improve the positioning effect of the communication cable 10 and enhance the protection strength of the communication cable 10.

[0018] In an embodiment of the present invention, the fastener includes bolt hole plates 13 installed on both sides of the end of the clamping ring. A fastening bolt 14 is threadedly connected between the opposite side walls of the two bolt hole plates 13. Locking nuts 15 are threadedly connected to the ends of the two fastening bolts 14. By rotating the locking nuts 15, the relative distance between the two bolt hole plates 13 is adjusted, so as to firmly clamp and position the communication cable 10 placed between the two clamping rings.

[0019] Refer to Figure 3 , The end of the limiting cone rod 20 facing the threaded hole groove 16 is connected with a connecting rod 19. The end of the connecting rod 19 is connected with a screw rod 18. A threaded hole 17 is opened in the inner wall of the threaded hole groove 16 corresponding to the end of the screw rod 18. The screw rod 18 is threadedly connected in the threaded hole 17, thereby controlling the detachable connection between the limiting cone rod 20 and the clamping ring.

[0020] In an example of the present invention, a plurality of friction pad strips 26 are annularly and equally spaced on the inner side of the clamping ring and distributed parallel to the axis. Under the blockage of the friction pad strips 26, a certain gap is maintained between the communication cable 10 and the inner wall of the clamping ring, that is, the full contact between the positioning clamp 11 and the outer wall of the communication cable 10 is reduced, affecting the heat dissipation inside the positioning clamp 11. At the same time, the surface of the friction pad strip 26 in contact with the outer side of the communication cable 10 is set to be corrugated, which is used to increase the friction force for clamping the communication cable 10, thereby improving the clamping stability of the clamping ring on the communication cable 10.

[0021] As a preferred embodiment of the present invention, refer to Figure 4, the swing positioning member includes a shaft groove 21 formed on the outer wall of the limit cone rod 20. Inside the shaft groove 21, a swing block 22 is rotatably connected through a swing shaft II 23. A reinforcing swing rod 24 is fixedly installed on the top of the swing block 22. When the reinforcing swing rod 24 is in a free state, the end away from the swing block 22 is inclined and distributed towards the conical end of the limit cone rod 20. Inside the shaft groove 21, a limit swing position block 25 is installed on the side facing the threaded hole groove 16. The limit swing position block 25 is used to limit the swing of the end of the reinforcing swing rod 24 away from the swing block 22 when it is pushed. When the limit swing position block 25 blocks the inner end wall of the reinforcing swing rod 24, it prevents its excessive swing and affects the positioning strength of the reinforcing swing rod 24. That is, when the end of the reinforcing swing rod 24 away from the swing block 22 is stressed and the swing shaft II 23 is controlled to swing until the other end of the reinforcing swing rod 24 contacts the limit swing position block 25, at this time, the inner surface of the reinforcing swing rod 24 is in full contact with the soil. At this time, the reaction force on the soil reaches the maximum. At this time, the structure uses the thrust generated by the soil offset to drive the reinforcing swing rod 24 to swing and simultaneously generate a reaction force on the soil, so as to improve the positioning protection of the positioning fixture 11 against the offset of the communication cable 10.

[0022] Since multiple groups of limit cone rods 20 and swing positioning members are arranged on the outside of the positioning fixture 11, no matter what direction the soil thrust comes from, the corresponding limit cone rods 20 and swing positioning members can be used to generate reaction forces, thereby expanding the positioning effect on the communication cable 10.

[0023] Specifically, the end of the reinforcing swing rod 24 is set as a conical structure to improve the smoothness of insertion into the soil.

[0024] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
