Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable installation turning guide device. Background Art

[0002] Cables are typically made up of several or several groups of conductors twisted together into a rope-like structure. Each group of conductors is insulated from each other and often twisted around a core. The entire structure is covered with a highly insulating coating. Cables are characterized by internal conduction and external insulation. Cables can also be made of one or more mutually insulated conductors covered with an insulating protective coating, transmitting power or information from one location to another. Overhead cables are specialized overhead conductors equipped with insulation and a protective sheath. They are manufactured using a process similar to cross-linked cable and represent a new power transmission method between overhead and underground cables. Turn guides are required during cable installation.

[0003] Currently, there are a variety of cable guide devices on the market, most of which are placed in corners. Most of these devices use pulleys, rollers, or guide wheels to guide the movement of cables. Among them, guide wheels are widely used in cable guidance due to their simple structure, low friction resistance, and flexible rotation.

[0004] However, conventional cable turning guide designs often overlook the dynamic tension changes in cables during turns, and how these changes affect the contact between the cable and the guide pulley. This not only causes the cable to sag or slip during turns, but also can exacerbate wear due to poor contact between the cable and the guide pulley, shortening the service life of both cables and the guide pulley. Therefore, a cable turning guide device was proposed to address these issues. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a cable installation turning guide device, which aims to improve the problem that the cable may become loose or slip during the turning process, and may also be aggravated by wear due to poor contact between the cable and the guide wheel, thereby shortening the service life of the cable and the guide wheel.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a cable installation turning guide device, comprising a support plate 1, with connecting plates 2 fixedly connected to the upper and lower ends of the support plate 1. The support plate 1 provides a stable support base for the entire device and connects the two connecting plates 2. The connecting plates 2 provide installation locations for an auxiliary tensioning mechanism 5 and a guide straightening mechanism 6. A guide wheel 4 is provided between the two connecting plates 2. The guide wheel 4 guides the cable during the turning process, allowing the cable to change direction smoothly, reducing friction and wear between the cable and other objects, and protecting the cable sheath.

[0033] The inner walls of the two connecting plates 2 are each provided with an auxiliary tensioning mechanism 5, and the auxiliary tensioning mechanism 5 includes a limit rod 502, and a limit groove 504 is provided on the inner wall of the connecting plate 2. Both ends of the limit rod 502 are fixedly connected to the limit groove 504, and the outer side of the limit rod 502 is slidingly connected to the moving block 501, and the outer side of the moving block 501 is slidingly connected to the inner wall of the limit groove 504. The limit rod 502 and the limit groove 504 ensure that the moving direction of the moving block 501 is stable, and prevent the moving block 501 from deviating under the action of the spring 503, thereby ensuring the accurate position of the guide wheel 4, so that the cable can always turn along the correct path.

[0034] A spring 503 is sheathed around the outer portion of the limiting rod 502. One end of the spring 503 is fixedly connected to the inner wall of the limiting slot 504, while the other end is fixedly connected to the outer side of the movable block 501. This arrangement of the spring 503 enables the guide wheel 4 to exert a certain tension on the cable. When the cable contacts the guide wheel 4, the spring 503 is compressed, generating a reverse elastic force that forces the guide wheel 4 to adhere tightly to the cable, preventing it from loosening or slipping. This helps improve cable stability during turns and reduces friction, wear, and entanglement caused by loose cables.

[0035] The two ends of the guide wheel 4 are rotatably connected between the two moving blocks 501, so as to provide an installation position for the guide wheel 4. The movement of the guide wheel 4 drives the two moving blocks 501 to move.

[0036] Reference Figure 1 and Figure 2 The front exterior of support plate 1 is provided with a fixing mechanism 3, which includes a connecting plate 301. One side of connecting plate 301 is hinged to the exterior of support plate 1. Connecting plate 301 can be flexibly rotated, allowing for easy adjustment of angle and position during installation to accommodate different installation environments and requirements. Multiple fastening screws 302 are threadedly connected to the inner walls of both support plate 1 and connecting plate 301, providing a secure fixing force for securing support plate 1 and connecting plate 301 to the wall.

[0037] Reference Figure 1 , Figure 2 and Figure 4 A guiding and straightening mechanism 6 is provided between the two connecting plates 2 to provide further guiding and straightening functions for the cable, ensuring that the cable can be subsequently installed more regularly after passing through the turning guide device, thereby improving the quality and reliability of cable laying. The guiding and straightening mechanism 6 includes a fixed frame 601 and a movable plate 603. The fixed frame 601 provides stable support for the entire guiding and straightening mechanism 6, and the movable plate 603 can be moved by a transmission assembly to guide and adjust the cable. The two cooperate to complete the guiding and straightening task. The bottom of the fixed frame 601 is fixedly connected to the top of the lower connecting plate 2 to ensure that the fixed frame 601 is firmly mounted on the device and will not loosen or shift due to the movement of the cable or the action of external force, providing a stable support base for the guide plate 1 602.

[0038] Guide plate 1 602 is fixedly connected to the top center of fixed frame 601. Guide plate 1 602 provides preliminary guidance and support, working with guide plate 2 604 to clamp and straighten the cable. A transmission assembly is located at the top of movable plate 603. This assembly precisely controls the movement of movable plate 603, adjusting the distance between guide plate 2 604 and guide plate 1 602 to accommodate cables of varying diameters and achieve varying degrees of cable guidance and straightening force. Guide plate 2 604 is fixedly connected to the bottom center of movable plate 603. Guide plate 2 604 and guide plate 1 602 are positioned opposite each other, working together to guide and straighten the cable.

[0039] A plurality of balls 608 are provided on opposite sides of the guide plate 1 602 and the guide plate 2 604. The provision of the balls 608 can reduce the friction between the cable and the guide plate, making the cable smoother when passing through the guide straightening mechanism 6 and avoiding wear of the cable sheath.

[0040] Reference Figure 2 and Figure 4 The transmission assembly includes a transmission screw 605, the outer thread of which is connected to the inner wall of the upper connecting plate 2. The top of the movable plate 603 is rotatably connected to the bottom of the transmission screw 605. By rotating the transmission screw 605, the movable plate 603 can be precisely controlled, thereby adjusting the distance between the second guide plate 604 and the first guide plate 602. The top of the transmission screw 605 is provided with anti-slip grooves 606. The anti-slip grooves 606 increase the friction of the top of the transmission screw 605, making it easier for the operator to apply force when rotating the transmission screw 605 and preventing slipping.

[0041] Reference Figure 1 and Figure 4A plurality of guide rods 607 are fixedly connected to both sides of the top of the fixed frame 601. The top of the guide rod 607 is fixedly connected to the bottom of the upper connecting plate 2. A through hole is opened inside the movable plate 603. The inner wall of the through hole is slidably connected to the outer side of the guide rod 607. The guide rod 607 provides a stable guide for the movement of the movable plate 603, ensuring that the movable plate 603 maintains a straight line motion during the up and down movement without deviation or shaking.

[0042] Working principle: First, rotate the connecting plate 301 so that the support plate 1 and the connecting plate 301 fit the wall surface, and fix the support plate 1 and the connecting plate 301 by fixing the fastening screws 302 to fix the device. Then when the cable contacts the guide wheel 4, the cable applies pressure to the guide wheel 4, and the pressure is transferred to the moving block 501. The moving block 501 slides in the limiting groove 504 and compresses the spring 503 outside the limiting rod 502. The spring 503 generates a reverse elastic force during the compression process, and this elastic force acts on the guide wheel 4 through the moving block 501, causing the guide wheel 4 to generate a certain tension on the cable. This ensures that the cable always maintains close contact with the guide wheel 4 during the turning process, preventing the cable from loosening or slipping.

[0043] The cable then passes between guide plate 1 602 and guide plate 2 604, which guide the cable. As the cable passes between the two clamping plates, it comes into contact with ball bearings 608. As the cable moves, ball bearings 608 roll, reducing friction between the cable and the clamping plates. The clamping of guide plates 1 602 and 2 604 on the cable also straightens it, making it more straight after passing between guide plates 1 602 and 2 604. This reduces cable bending and makes installation and routing easier.

[0044] By rotating the anti-slip groove 606 on the top of the drive screw 605, the drive screw 605 causes the movable plate 603 to move up and down, guided by the guide rod 607. As the movable plate 603 moves downward, the second guide plate 604 at the bottom of the movable plate 603 approaches the first guide plate 602 at the top center of the fixed frame 601, guiding the cables passing between them. By adjusting the drive screw 605, the guiding force of the guide plates 1 602 and 2 604 on the cables can be controlled, and the cable can be accommodated with cables of different sizes.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
