Description

Technical Field

[0001] This utility model relates to the field of power cable installation and fixing technology, specifically to a power cable anti-friction structure. Background Technology

[0002] Power cables are special conductors used to transmit and distribute electrical energy. They are widely used in power systems and undertake the key task of transmitting electrical energy from the generation end to the consumption end. Their core function is to establish electrical connections between different power equipment, lines or systems to achieve efficient and safe transmission of electrical energy. Currently, in some areas, cables are installed close to buildings or other external objects. During long-term use, the friction between the cables and these objects damages the cable's outer protective sheath, affecting the cable's lifespan and potentially causing safety issues. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary conveying device for the installation of an air conditioner outdoor unit, in order to solve the problem mentioned in the background art that in some areas, the cables are closely attached to buildings or other objects, and during long-term use, the friction between the cables and the buildings or other objects causes damage to the cable's outer protective sleeve, affecting the cable's service life and easily leading to safety problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary conveying device for installing an air conditioner outdoor unit, comprising a cable body, a cable protection component sleeved on the outside of the cable body, a first arc-shaped support frame and a second arc-shaped fixing frame symmetrically engaged on the outside of the cable protection component, connecting horizontal plates fixedly connected to both sides of the first arc-shaped support frame and the second arc-shaped fixing frame, two connecting horizontal plates at the top of the side of the first arc-shaped support frame symmetrically provided with connecting screws, two connecting horizontal plates on both sides of the second arc-shaped fixing frame having circular through holes matching the connecting screws, locking nuts threaded to the bottom ends of the four connecting screws, the top surface of the locking nuts contacting the bottom surface of the connecting horizontal plates on both sides of the second arc-shaped fixing frame, and anti-friction components fixedly installed at equal angles on the outside of the first arc-shaped support frame and the second arc-shaped fixing frame. This structure can reduce the damage to the parts in contact with the cable body caused by the external environment, extend the service life of the cable, and ensure safe use.

[0005] Preferably, the cable protection assembly includes an anti-slip connection positioning sleeve, which is movably fitted onto the outside of the cable body. A snap-fit ​​block is fixedly connected to the top center of the anti-slip connection positioning sleeve. The anti-slip connection positioning sleeve is used to provide initial protection for the contact points between the cable body and the external environment.

[0006] Preferably, the anti-slip connecting positioning sleeve has a snap-fit ​​groove in the middle of the bottom plate that matches the snap-fit ​​block, and the anti-slip connecting positioning sleeve has a through positioning rectangular groove in the middle, which is used to cooperate with the positioning insert to keep the first arc-shaped support frame, the second arc-shaped fixing frame and the anti-slip connecting positioning sleeve relatively stationary, preventing the three from separating.

[0007] Preferably, the anti-friction component includes multiple sets of fixed vertical plates, which are symmetrically and at equal angles fixedly connected to the outside of the first arc-shaped support frame and the second arc-shaped fixed frame. The symmetrically distributed fixed vertical plates are rotatably connected to a rotating shaft, and a rotating wheel is rotatably sleeved on the middle of the outer side of the rotating shaft. When the rotating wheel comes into contact with the rotating shaft and the external object, it converts friction into rotation, thereby reducing damage to the cable body.

[0008] Preferably, a mating groove is provided at the middle of one end of the first arc-shaped support frame and the second arc-shaped fixing frame that are close to each other. The mating groove matches the outer edge of the side bottom plate and top plate of the anti-slip connecting positioning sleeve to form a relatively tight connection structure, preventing the first arc-shaped support frame, the second arc-shaped fixing frame and the anti-slip connecting positioning sleeve from rotating relative to each other.

[0009] Preferably, a positioning block is fixedly connected to the middle of the bottom end of a connecting horizontal plate on the side of the first arc-shaped support frame. The positioning block and the positioning rectangular groove are matched and engaged to limit the positioning of the first arc-shaped support frame, the second arc-shaped fixing frame and the anti-slip connecting positioning sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By designing an anti-slip connection positioning sleeve that can be snapped onto the outside of the cable, the external protection of the cable can be enhanced. At the same time, the anti-slip connection positioning sleeve, the first arc-shaped support frame, and the second arc-shaped fixing frame are fixed in position to each other, forming a stable protective structure. By designing a fixed vertical plate, a rotating shaft, and a rotating wheel, it can be individually fixed at the point where the cable contacts external objects. The rotating shaft and rotating wheel convert friction, reducing damage to the cable body, extending the cable's service life, and further ensuring safety in use. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figure 1-4 The system includes a cable body 1, a cable protection assembly sleeved on the outside of the cable body 1, a first arc-shaped support frame 2 and a second arc-shaped fixing frame 3 symmetrically snapped onto the outside of the cable protection assembly, connecting horizontal plates 7 fixedly connected to both sides of the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3, connecting screws 8 symmetrically inserted through the two connecting horizontal plates 7 at the top of the side of the first arc-shaped support frame 2, and circular through holes matching the connecting screws 8 on both sides of the second arc-shaped fixing frame 3, with locking nuts 9 threaded to the bottom of the four connecting screws 8, the top surface of the locking nuts 9 contacting the bottom surface of the connecting horizontal plates 7 on both sides of the second arc-shaped fixing frame 3, and anti-friction components fixedly installed at equal angles on the outside of the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3.

[0015] Furthermore, the cable protection assembly includes an anti-slip connection positioning sleeve 10, which is movably sleeved on the outside of the cable body 1, and a snap-fit ​​block 12 is fixedly connected to the top center of the anti-slip connection positioning sleeve 10.

[0016] Furthermore, the anti-slip connecting positioning sleeve 10 has a snap-fit ​​groove 11 in the middle of its base plate that matches the snap-fit ​​block 12, and a through positioning rectangular groove 13 in the middle of its base plate.

[0017] Furthermore, the anti-friction component includes multiple sets of fixed vertical plates 4, which are symmetrically and at equal angles fixed to the outside of the first arc-shaped support frame 2 and the second arc-shaped fixed frame 3. The symmetrically distributed fixed vertical plates 4 are rotatably connected to a rotating shaft 5. A rotating wheel 6 is rotatably sleeved on the middle of the outer side of the rotating shaft 5. When the cable body 1 is subjected to external force and slides, the surface of the rotating wheel 6 comes into contact with the external environment, causing the rotating wheel 6 to shake. The friction force is converted through the rotating wheel 6, and at the same time, the external environment of the cable body 1 is isolated through the rotating wheel 6.

[0018] Furthermore, a mating groove 15 is provided at the middle of one end of the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3 that are close to each other. The mating groove 15 matches the outer edge of the side bottom plate and top plate of the anti-slip connecting positioning sleeve 10.

[0019] Furthermore, a positioning block 14 is fixedly connected to the bottom center of a connecting horizontal plate 7 on the side of the first arc-shaped support frame 2, and the positioning block 14 and the positioning rectangular groove 13 are matched and engaged.

[0020] This structure is installed every 1.5m-2m along the straight section of the cable body 1 to ensure that the deflection caused by the cable's own weight is ≤5mm / m. One set is installed at the start, middle, and end points of bends, with the distance between sets shortened to 0.8m-1.2m to prevent stress concentration at bends and increased friction. Near building contact points, an additional set is installed 300mm on each side of the contact point to reinforce the contact section and prevent excessive friction at a single point. For single cable lengths ≤50m, at least 3 sets are installed, with one additional set for every additional 20m. When crossing buildings or narrow spaces, the density is increased to one set every 0.5m-1m to ensure no exposed sections directly contact external objects. When protection of the outside of the cable body 1 is required, first, the anti-slip connection positioning sleeve 10 is moved to enlarge its opening until it can be fitted onto the outside of the cable body 1. After fitting the anti-slip connection positioning sleeve 10 onto the outside of the cable body 1, press down on the side of the anti-slip connection positioning sleeve 10. The top and bottom plates of the sleeve allow the snap-fit ​​block 12 to enter the snap-fit ​​groove 11. Depending on the actual situation, connecting adhesive can be applied to the inner side of the anti-slip connecting positioning sleeve 10 to increase the connection stability between the anti-slip connecting positioning sleeve 10 and the cable body 1. Then, the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3 are placed below and above the anti-slip connecting positioning sleeve 10, respectively, so that the positions of the positioning rectangular groove 13 and the positioning plug 14 correspond. The first arc-shaped support frame 2 and the second arc-shaped fixing frame 3 are connected together, so that the positioning plug 14 is inserted into the positioning rectangular groove 13. Then, the connecting screw 8 and the locking nut 9 are used to connect and fix the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3, so that the inner side of the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3 contacts the outer side of the anti-slip connecting positioning sleeve 10. At the same time, after the first arc-shaped support frame 2 and the second arc-shaped fixing frame 3 are connected and fixed by the connecting screw 8 and the locking nut 9, the outer side of the top and bottom plates of the anti-slip connecting positioning sleeve 10 fits with the mating groove 15.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
