Description

Technical Field

[0001] This utility model relates to the field of power line laying technology; specifically, this utility model relates to an anti-tangling power line laying device for power construction. Background Technology

[0002] Power line laying is a crucial step in power engineering construction, involving the laying, connecting, tightening, and fixing of conductors, ground wires, or cables. With the development of the power industry, traditional manual laying methods are no longer sufficient to meet current power line laying needs. Therefore, specialized laying devices for power line construction have emerged.

[0003] For example, in the prior art, patent CN119460873A discloses an anti-tangling wire laying device for power construction. It uses a locking ratchet and ratchet block to unidirectionally lock the rotation direction of the wire roll, preventing sudden wire breakage during laying from causing the wire roll to rotate in the opposite direction due to inertia, thus preventing the wire roll from loosening and tangling. This design can prevent wire tangling. However, the above-mentioned prior art still has the following drawbacks:

[0004] (1) Since the height of the central cylinder used to support the rotation of the wire roll is fixed, it is necessary to manually lift the wire roll before putting it on the central cylinder during the installation process. This method is extremely inconvenient, especially when the wire laying distance is long and the wire roll is heavy. Manual installation is extremely inconvenient and poses certain safety hazards.

[0005] (2) After the wire roll is installed on the central cylinder, the pressure of the wire roll is directly applied to the central cylinder. The wire roll is only supported by the wire feeding side plate located on one side of it, and the force applied by the wire roll to the wire feeding side plate is unbalanced, which can easily cause the wire feeding side plate to tilt. In particular, the heavier the wire roll, the greater the safety hazard. Utility Model Content

[0006] In view of this, the present invention provides an anti-tangling power construction cable laying device for power construction, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0007] To achieve the aforementioned objectives, this utility model provides an anti-tangling power line laying device for power construction, comprising a fixed support and a movable support that are relatively distributed and have adjustable spacing. A fixed-side turntable and a movable-side turntable are rotatably mounted on the fixed support and the movable support, respectively, and a rotating roller is provided between the fixed-side turntable and the movable-side turntable.

A ring of ratchet grooves is provided on both the fixed-side turntable and the movable-side turntable, and a ratchet block capable of being raised and lowered and engaging with one of the ratchet grooves is provided on the fixed support and the movable support.

[0008] Optionally, both the fixed support and the movable support are provided with a longitudinal plate at their top ends.

[0010] Optionally, the positioning rod includes a positioning section with one end capable of being inserted into a positioning groove, a pressing section connected to the other end of the positioning section and capable of extending from the roller toward the movable side turntable, and a first elastic telescopic rod disposed between the positioning section and the pressing section and capable of lateral movement. When the end of the pressing section is pressed into the roller, the first elastic telescopic rod is compressed and stores force for the positioning section to insert into the positioning groove.

[0011] Optionally, a slidable support arm parallel to the strip groove is provided in the middle of the rotating roller. A locking groove is provided in the middle of the side of the support arm facing the movable support. A locking rod that can be inserted into the locking groove is slidably provided in the rotating roller. A second elastic telescopic rod that can move laterally is provided in the rotating roller. The protruding end and the fixed end of the second elastic telescopic rod are respectively fixedly connected to the opposite ends of the locking rod and the extrusion section. The movable end of the first elastic telescopic rod is fixedly connected to the positioning section. The positioning rod also includes a connecting section that fixes the fixed end of the first elastic telescopic rod to the fixed end of the second elastic telescopic rod.

[0012] Optionally, the connecting section is configured to include a straight rod section and two curved rod sections in the shape of an "U". One end of the straight rod section is fixedly connected to the fixed end of the first elastic telescopic rod. One opposite end of each of the two curved rod sections is fixedly connected to the other end of the straight rod section. The other opposite ends of the curved rod sections are respectively fixed on the side of the fixed end of the second elastic telescopic rod. The support arm is located between the two curved rod sections. The surface of the rotating roller is provided with a through groove for displacement of the curved rod sections.

[0013] Optionally, a sleeve is fixedly installed inside the rotating roller and sleeved outside the extrusion section.

Both ends of the lead screw are rotatably mounted on the base.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] By designing the rotating rollers to move radially outward along both the fixed and movable turntables, the rollers can be positioned close to the ground when installing the cable reel, eliminating the need for manual lifting of the cable reel for installation. This saves time and effort. After the cable reel is installed, the fixed turntable drives the rotating rollers to rotate, and the weight of the reel and rollers allows them to synchronously return to the center position of the fixed turntable, making operation convenient. Furthermore, the cable reel remains supported by the ground when it is fitted onto the rotating rollers, preventing it from tipping over and enhancing safety. Attached Figure Description

Detailed Implementation

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0026] Please refer to Figures 1 to 6 As shown, the present invention relates to an anti-tangling power construction cable laying device for power construction, comprising a fixed support 1 and a movable support 2 that are relatively distributed and have adjustable spacing. A fixed side turntable 3 and a movable side turntable 4 are rotatably mounted on the fixed support 1 and the movable support 2, respectively. A rotating roller 5 is provided between the fixed side turntable 3 and the movable side turntable 4. A fixed side slider 6 and a movable side slider 7 that can be displaced radially are provided on the fixed side turntable 3 and the movable side turntable 4, respectively. One end of the rotating roller 5 is fixedly connected to the fixed side slider 6, and the other end of the rotating roller 5 is inserted into the movable side slider 7. A positioning groove 8 is provided in the center of the fixed side turntable 3, and a positioning rod 9 that can be pressed into the positioning groove 8 by the movable side slider 7 is provided in the center of the rotating roller 5. A ratchet groove 10 is provided on both the fixed side turntable 3 and the movable side turntable 4, and a ratchet block 11 that can be raised and lowered and engages with one of the ratchet grooves 10 is provided on the fixed support 1 and the movable support 2.

[0027] In this embodiment, when installing the wire reel to be laid:

[0028] First, move the movable support 2 away from the fixed support 1 to provide space for the positioning rod 9 to be pulled out of the positioning slot 8. Then, the positioning rod 9 is pulled out of the positioning slot 8.

[0029] The second step is to push the rotating roller 5 outward. The rotating roller 5 causes the fixed side slider 6 and the movable side slider 7 to move radially outward on the fixed side turntable 3 and the movable side turntable 4, respectively, until the rotating roller 5 moves to the outermost position in the radial direction. Then, rotate the fixed side turntable 3 and the movable side turntable 4 so that the rotating roller 5 is at the position with the minimum distance from the ground.

[0030] Third step: Continue to move the movable support 2 away from the fixed support 1 so that the movable support 2 is separated from the rotating roller 5, and then put the suspended end of the wire reel rotating roller 5 onto the rotating roller 5.

[0031] Fourth step: Rotate the fixed side turntable 3 so that the rotating roller 5 carries the wire roll and moves upward in a circular motion. When the line connecting the center of the rotating roller 5 and the center of the fixed side turntable 3 is inclined upward at the outer end, the rotating roller 5 can move to the center position inside the fixed side turntable 3 under its own weight and the weight of the wire roll, so that the positioning rod 9 is aligned with the positioning groove 8.

[0032] Fifth step: Push the movable support 2 to one side of the fixed support 1 so that the movable side slider 7 is fitted onto the rotating roller 5. During this process, the movable side slider 7 applies a squeezing force to the positioning rod 9 so that the positioning rod 9 is reinserted into the positioning groove 8, thereby fixing the rotating roller 5 at the center position between the fixed side turntable 3 and the movable side turntable 4.

[0033] As can be seen from the above usage process in this embodiment:

[0034] Firstly, by lowering the rotating roller 5 to its lowest position, when installing the wire roll to be laid, there is no need to manually lift the wire roll to a high position; the wire roll can simply be moved horizontally onto the rotating roller 5, making the wire laying operation more convenient.

[0035] Secondly, by rotating the fixed-side turntable 3, the wire roll and the rotating roller 5 can move to the center position of the fixed-side turntable 3 by their own gravity.

[0036] Thirdly, during the process of reconnecting the rotating roller 5 to the movable support 2, the positioning rod 9 can be pushed into the positioning groove 8 to fix the rotating roller 5 in the center position.

[0037] Fourthly, by setting ratchet block 11 and ratchet groove 10, the fixed side turntable 3 and the movable side turntable 4 can be locked in one direction in a timely manner to prevent the fixed side turntable 3 and the movable side turntable 4 from rotating in opposite directions. This not only improves stability during the operation of the fifth step mentioned above, but also makes the implementation of the fifth step easier. Furthermore, it can prevent the cable from becoming loose and tangled after the wire breaks and reverses.

[0038] Specifically, in this embodiment, both the fixed support 1 and the movable support 2 are provided with a longitudinal plate 12 at their top ends. A movable sleeve 13 is slidably fitted around the outside of the longitudinal plate 12. A pull-down spring 14 is provided between the top end of the longitudinal plate 12 and the sleeve 13, and a ratchet block 11 is fixed to the top end of the sleeve 13. The pull-down spring 14 provides a stable force for the ratchet block 11 to insert into the ratchet groove 10 by applying a downward pulling force to the sleeve 13.

[0039] Specifically, in this embodiment, a base 23 is also included. A transverse slide rail 24 is provided on the base 23, and a slide block 25 is slidably disposed on the transverse slide rail 24. The fixed support 1 is fixedly connected to the base 23, and the movable support 2 is fixedly connected to the slide block 25. A threaded sleeve 26 is fixedly connected to the bottom of the movable support 2. A lead screw 27 is threaded through the internal thread of the threaded sleeve 26, and both ends of the lead screw 27 are rotatably mounted on the base 23. By rotating the lead screw 27 forward or backward, the movable support 2 can be controlled to move away from or closer to the fixed support 1 using the threaded sleeve 26 and the slide block 25.

[0040] The inner surface of the movable side slider 7 is provided with a square slot 15, and the end of the rotating roller 5 facing the movable side turntable 4 is shaped to fit the slot 15. This arrangement ensures that the fixed side turntable 3 and the movable side turntable 4 can rotate synchronously with the rotating roller 5. Therefore, during the wire feeding operation, the two ends of the rotating roller 5 are driven simultaneously by the fixed side turntable 3 and the movable side turntable 4, thereby improving the stability of wire feeding.

[0041] Specifically, in this embodiment, the positioning rod 9 includes a positioning section 9.1 with one end capable of being inserted into the positioning groove 8, a pressing section 9.2 connected to the other end of the positioning section 9.1 and capable of extending from the roller 5 toward the movable side turntable 4, and a first elastic telescopic rod 9.3 disposed between the positioning section 9.1 and the pressing section 9.2 and capable of lateral movement. When the end of the pressing section 9.2 is pressed into the roller 5, the first elastic telescopic rod 9.3 is compressed and stores force for the positioning section 9.1 to insert into the positioning groove 8.

[0042] As the movable slider slides onto the end of the rotating roller 5, a force is applied to the extrusion section 9.2, which in turn applies a force to the fixed end of the first elastic telescopic rod 9.3. At this time, even if the positioning rod 9 is not aligned with the positioning groove 8, the first elastic telescopic rod 9.3 can compress itself to allow the subsequent positioning rod 9 to be aligned with the positioning groove 8 and then inserted into the positioning groove 8 to store force. Thus, even if the positioning rod 9 and the positioning groove 8 are not aligned, the movable slider 7 can be put onto the rotating roller 5 first.

[0043] With this setup, the operations in steps four and five above can be adjusted as follows: First, move the movable support 2 to one side of the fixed support 1, causing the movable side slider 7 to be fitted onto the rotating roller 5. At this time, the first elastic telescopic rod 9.3 is compressed. Then, the fixed side turntable 3 and the movable side turntable 4 can be rotated simultaneously to drive the wire coil to make an upward circular motion, which has stronger stability, and the fixed support 1 will not tip over due to unilateral force. Afterward, when the wire coil and the rotating roller 5 move inward to the center position under their own weight, the first elastic telescopic rod 9.3 can cause the positioning rod 9 to automatically insert into the positioning groove 8.

[0044] Furthermore, a sliding support arm 16 parallel to the strip groove 28 is provided in the middle of the rotating roller 5. A locking groove 17 is provided in the middle of the side of the support arm 16 facing the movable support 2. A locking rod 18 that can be inserted into the locking groove 17 is slidably provided in the rotating roller 5. A second elastic telescopic rod 19 that can move laterally is provided in the rotating roller 5. The protruding end and the fixed end of the second elastic telescopic rod 19 are respectively fixed to the opposite ends of the locking rod 18 and the extrusion section 9.2. The movable end of the first elastic telescopic rod 9.3 is fixed to the positioning section 9.1. The positioning rod 9 also includes a connecting section that fixes the fixed end of the first elastic telescopic rod 9.3 to the fixed end of the second elastic telescopic rod 19.

[0045] The support arm 16 allows the outer diameter of the rotating roller 5 to be smaller than the inner diameter of the wire roll. After the wire roll is fitted with the rotating roller 5, when both ends of the support arm 16 extend out of the rotating roller 5 by the same length, that is, when the locking rod 18 is inserted into the locking groove 17, the support arm 16 supports the wire roll, so that the wire roll and the rotating roller 5 are aligned.

[0046] The second elastic telescopic rod 19 provides force for the locking rod 18 to insert into the locking groove 17, and when the positioning rod 9 is pulled out of the positioning groove 8, the second elastic telescopic rod 19 pulls the locking rod 18 out of the locking groove 17. This arrangement ensures that when the rotating roller 5 is at its lowest position, since the locking rod 18 has been pulled out of the locking groove 17, the support arm 16 can slide freely on the rotating roller 5. Furthermore, during the process of putting the wire coil onto the rotating roller 5, if the wire coil and the rotating roller 5 are eccentric, the support arm 16 can be moved to ensure that it can enter the interior of the wire coil.

[0047] It should be noted that the length of the support arm 16 should be set to match the inner diameter of the wire reel.

[0048] After making the above settings:

[0049] On one hand, when the fixed-side turntable 3 and the movable-side turntable 4 are rotated, causing the wire roll and the rotating roller 5 to move to the center position by their own weight, the support arm 16, under the action of the wire roll, moves radially along the rotating roller 5. During this process, the second elastic telescopic rod 19 has already stored force for the locking rod 18. When the wire roll moves to the center position with the rotating roller 5 under its own weight, the locking groove 17 is exactly aligned with the locking rod 18. Then, the locking rod 18 can automatically insert into the locking groove 17 under the action of the second elastic telescopic rod 19, fixing the wire roll and the rotating roller 5 in the center position, and the support arm 16 is stably supported on the inner wall of the wire roll.

[0050] On the other hand, since both the first elastic telescopic rod 9.3 and the second elastic telescopic rod 19 can be compressed, the two working conditions of the positioning rod 9 being inserted into the positioning groove 8 and the locking rod 18 being inserted into the locking groove 17 will not interfere with each other and can be carried out simultaneously or separately.

[0051] Specifically, in this embodiment, the support arm 16 is configured as a rectangular plate structure. When the wire coil drives the support arm 16 to move radially along the rotating roller 5 to align the wire coil with the roller 5, the locking rod 18, under the pressure of the second elastic telescopic rod 19, slides on the surface of the support arm 16 at one end facing the locking groove 17. Furthermore, a roller is provided at the end of the locking rod 18 facing the support arm 16 for rolling on the surface of the support arm 16, reducing the friction between the locking rod 18 and the support arm 16. Both ends of the support arm 16 are provided with arc-shaped support plates for abutting against the inner wall of the wire coil drum.

[0052] Furthermore, the connecting section is configured to include a straight rod section 9.4 and two U-shaped bent rod sections 9.5. One end of the straight rod section 9.4 is fixedly connected to the fixed end of the first elastic telescopic rod 9.3. One opposite end of each of the two bent rod sections 9.5 is fixedly connected to the other end of the straight rod section 9.4. The other opposite ends of the bent rod sections 9.5 are respectively fixed to the side of the fixed end of the second elastic telescopic rod 19, and the support arm 16 is located between the two bent rod sections 9.5. The surface of the rotating roller 5 is provided with a through groove 20 for the displacement of the bent rod sections 9.5. By setting the straight rod section 9.4 and the bent rod section 9.5, the positioning rod 9 passes through the area of ​​the support arm 16 and goes around the outside of the support arm 16, thus not affecting the movement of the support arm 16.

[0053] Specifically, in this embodiment, a sleeve 21 is fixedly installed inside the roller 5, which is sleeved outside the extrusion section 9.2. An outward push spring 22 is provided between the sleeve 21 and the extrusion section 9.2 to provide force for the end of the extrusion section 9.2 extending towards the movable support 2 and the roller 5. Specifically, the depth to which the positioning rod 9 is inserted into the positioning groove 8 is the same as the depth to which the locking rod 18 is inserted into the locking groove 17, and the compression strokes of the first elastic telescopic rod 9.3 and the second elastic telescopic rod 19 are the same, while the compression stroke of the extension spring is greater than the compression strokes of the first elastic telescopic rod 9.3 and the elastic telescopic rod 19. This configuration ensures that when the movable slider 7 is pulled out of the rotating roller 5, the first elastic telescopic rod 9.3, the second elastic telescopic rod 19, and the push spring 22 all undergo a reset process. After the first elastic telescopic rod 9.3 and the second elastic telescopic rod 19 are reset, the push spring 22 remains compressed. Consequently, during the subsequent reset process of the push spring 22, it enables the positioning rod 9 to continue moving as a whole, ensuring that the positioning rod 9 is pulled out of the positioning groove 8 and the locking rod 18 is pulled out of the locking groove 17.

[0054] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
