Detailed Implementation

[0025] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] Example 1: As Figure 1-2As shown, a cable laying tool includes: a rotating component 1 and a supporting component 2; the rotating component 1 includes: a first cylindrical portion 11 and a first limiting member 12, the first cylindrical portion 11 is used to pass through the cable reel, and the length of the first cylindrical portion 11 is greater than the length of the through hole of the cable reel; the open end of the first cylindrical portion 11 passes through the first limiting member 12 and is connected to the first limiting member 12; the maximum distance between the edge of the first limiting member 12 and the first cylindrical portion 11 is less than the distance between the peripheral wall of the cable reel and the first cylindrical portion 11; the supporting component 2 includes: a rod body 21 and a base 22, the rod body 21 is used to pass through the first cylindrical portion 11, and the length of the rod body 21 is greater than the length of the first cylindrical portion 11; the base 22 is connected to the end of the rod body 21.

[0027] In practice, the cable reel typically consists of two circular chucks and a cylindrical central shaft. The two circular chucks are located on both sides of the cylindrical central shaft, and the cable is wound around the surface of the central shaft.

[0028] In this embodiment, the cable laying tool is set up in two parts. After the first cylindrical part 11 of the rotating component 1 is inserted into the cable reel in a flat state, the rod 21 on the supporting component 2 is inserted into the first cylindrical part 11. Then, the cable reel is lifted upward by holding the first cylindrical part 11 that passes through the cable reel. During the lifting process, the side wall of the base 22 abuts against the ground. After the abutment point is used as the fulcrum, the cable reel can be easily erected by using the lever principle. After the cable reel is erected, the cable reel is placed on the surface of the first limiting component 12 and the first cylindrical part 11 is pressed against the rod 21 under its own weight. When the cable is pulled, the cable reel rotates, and the cable reel drives the first cylindrical part 11 to rotate around the rod 21.

[0029] Since the rotating component 1 needs to be horizontally inserted through the through hole of the cylindrical central shaft when the cable reel is in a flat position, the first limiting member 12 should not be too large. This is to prevent the height of the free end of the first cylindrical portion 11 from always being higher than the through hole of the cylindrical central shaft when the first limiting member 12 is in contact with the ground, thus making it difficult for the first cylindrical portion 11 to completely pass through the through hole of the cylindrical central shaft. Therefore, in this embodiment, the maximum distance between the edge of the first limiting member 12 and the first cylindrical portion 11 is limited to less than the distance between the peripheral wall of the cable reel and the first cylindrical portion 11. Exemplary, such as Figure 1 As shown, the first limiting member 12 consists of two intersecting plates, the length of which should be less than the diameter of the circular chuck on the cable reel.

[0030] Example 2: To better achieve the assembly of support member 2 and rotating member 1 while ensuring the stability of support member 2, improvements were made based on Example 1, such as... Figure 1-2As shown, in this embodiment, the distance between the edge of the base 22 and the first cylindrical portion 11 is a, the distance between the edge of the first limiting member 12 and the first cylindrical portion 11 is b, and the distance between the peripheral wall of the cable reel and the first cylindrical portion 11 is c, where c ≥ a > b.

[0031] In practical implementation, the base 22 needs a certain contact area with the ground to ensure stability, which is crucial for the stability of the supporting member 2 during the rotation of the cable reel. Therefore, in this embodiment, the base 22 is larger than the first limiting member 12. Similar to embodiment 1 where the first limiting member 12 is smaller than the circular chuck, the base 22 is smaller than the circular chuck to easily pass the rod 21 on the supporting member 2 through the horizontal first cylindrical portion 11. To ensure the supporting stability of the supporting member 2 as much as possible and to reduce the force required to lift the cable reel, the distance between the edge of the base 22 and the central axis of the first cylindrical portion 11 can be equal to the radius of the circular chuck.

[0032] Example 3: To increase the structural strength of the base 22, improvements were made based on Example 2, such as... Figure 1-2 As shown, in this embodiment, the base 22 includes: a first support plate 221, at least two first support plates 221 are provided, the ends of the two first support plates 221 are connected to the rod body 21, and the included angle between the two first support plates 221 is α, 0°<α<180°.

[0033] In the specific implementation process, such as Figure 1-2 As shown, the black-shaded part on the side is the first support plate 221. During the lifting of the cable reel, the free ends of the two first support plates 221 abut against the ground, forming a triangular structure. At this time, the stability of the base 22 under the weight of the cable reel is better. The included angle between the two first support plates 221 can be 90°.

[0034] Example 4: To further increase the stability of the base 22, improvements were made based on Example 3, such as... Figure 1-2 As shown, in this embodiment, the base 22 further includes a first base plate 222, the end of which is connected to the rod 21, and the first base plate 222 is provided on the opposite side of each first support plate 221.

[0035] In the specific implementation process, since the supporting member 2 is in a vertical state during the layout process, the balance around it is quite important. If only two first support plates 221 are set, the balance will be poor. In this embodiment, a first base plate 222 is added opposite to the first support plate 221.

[0036] Exemplary, such as Figure 2 As shown, the base 22, which consists of two first support plates 221 and two first base plates 222, is cross-shaped.

[0037] Example 5: To better support the first support plate 221 against the ground, improvements were made based on Example 4, such as... Figure 1-2 As shown, in this embodiment, the length of the first support plate 221 is the same as the length of the first base plate 222, and the weight of the first support plate 221 is greater than that of the first base plate 222.

[0038] In the specific implementation process, when the rod 21 on the support member 2 is horizontally inserted into the first cylinder 11, it is difficult to directly ensure that the line connecting the free ends of the two first plates is parallel to the ground. Therefore, in this embodiment, the weight of the first support plate 221 is greater than that of the first base plate 222. As a result, under the gravity of the first support plate 221, the rod 21 rotates, and the line connecting the free ends of the two first plates rotates to be basically parallel to the ground. Therefore, when lifting the cable reel, it is not necessary to adjust the position of the cable reel while bearing its weight so that the two first plates abut against the ground to form a fulcrum. Thus, after adopting the base 22 of this embodiment, the process of lifting the cable reel is more labor-saving.

[0039] As an example, the first support plate 221 uses a metal with a higher density than the first base plate 222, which allows the first support plate 221 to have a higher weight when it has the same volume as the first base plate 222.

[0040] As an example, the first support plate 221 and the first base plate 222 are made of the same metal, but the thickness of the first support plate 221 is greater than that of the first base plate 222.

[0041] Example 6: To further improve the structural stability of the base 22, improvements were made based on Example 4, such as... Figure 1-2 As shown, in this embodiment, the base 22 further includes a reinforcing plate 223, which has a triangular structure. The first right-angle end of the reinforcing plate 223 is connected to the side wall of the rod 21, and the second right-angle end of the reinforcing plate 223 is connected to the first support plate 221 and / or the first base plate 222.

[0042] In the specific implementation process, since the rod 21 and the base 22 are subjected to significant forces during the lifting of the cable reel, a reinforcing plate 223 is additionally provided between the first support plate 221 and the rod 21 to prevent damage to both and changes in their relative positions. The reinforcing plate 223 can at least reduce or prevent changes in the angle between the rod 21 and the first support plate 221. Of course, to further increase the connection stability between the rod 21 and the first base plate 222, a reinforcing plate 223 can also be provided between the rod 21 and the first base plate 222.

[0043] Example 7: To facilitate the rotation of the first cylinder around the rod 21, improvements were made based on Examples 1-6, such as... Figure 3-4As shown, in this embodiment, the end of the rod 21 away from the base 22 is provided with a protrusion 211, and the area of ​​the end of the protrusion 211 away from the base 22 is smaller than the cross-sectional area of ​​the rod 21.

[0044] In practice, the first cylinder presses against the end of the rod 21 under the weight of the cable reel. If the contact area between the rod 21 and the first cylinder is too large, the rod 21 may restrict the rotation of the first cylinder. Consequently, during the cable unwinding process, the rotation of the cable reel is hindered, making the unwinding process more laborious. This embodiment, by providing the protrusion 211, reduces the contact area between the rod 21 and the first cylinder, which is beneficial for the aforementioned unwinding operation.

[0045] As an example, the protrusion 211 can be as follows Figure 4 As shown, the whole structure is conical, while the ends are curved.

[0046] Example 8: To increase the structural strength of the protrusion 211, improvements were made based on Example 7, such as... Figure 3 As shown, in this embodiment, the end of the protrusion 211 away from the base 22 is a plane perpendicular to the central axis of the rod 21.

[0047] In specific implementation, although the free end of the protrusion 211 is as follows Figure 4 The curved surface shown is more conducive to the rotation of the first cylinder 11, but the protrusion 211 is prone to damage during long-term use. Therefore, this embodiment changes the aforementioned curved surface to a flat surface. Although this will reduce the rotational freedom of the first cylinder 11 to some extent, it can improve the structural strength of the protrusion 211. If there is a certain gap between the inner wall of the first cylinder 11 and the rod 21, the protrusion 211 on the curved surface may also cause the first cylinder 11 to deflect, especially when pulling the cable, while the flat surface can reduce or avoid the aforementioned deflection.

[0048] Example 9: To enable the cable delivery tool for small-diameter cable reels to be used for large-diameter cable reels, improvements were made based on Example 7, such as... Figure 1 and Figure 5-6 As shown, in this embodiment, the first limiting member 12 includes: a second support plate 121 and a second base plate 122. At least two second support plates 121 are provided, and the ends of both second support plates 121 are connected to the first cylindrical portion 11. The included angle between the two second support plates 121 is β, where 0° < β < 180°. The second base plate 122 is connected to the first cylindrical portion 11 at its end, and a second base plate 122 is provided on the opposite side of each second support plate 121. The length of the second support plate 121 is the same as the length of the second base plate 122, and the weight of the second support plate 121 is greater than that of the second base plate 122.

[0049] In specific implementation, the first limiting member 12 can be a disc, but in order to allow the support member 2 in the cable laying tool used for small-sized cable reels to directly serve as the rotating member 1 in the cable laying tool used for large-sized cable reels. In the following description, the first cable laying tool is for small-sized cable reels, and the second cable laying tool is for large-sized cable reels. Since the base 22 in the first cable laying tool can serve as the first limiting member 12 in the second cable laying tool, their structures are identical, and thus... Figure 1 As shown, the first limiting member 12 and the base 22 have the same structure but different sizes.

[0050] Example 10: To enable the cable delivery tool for small-diameter cable reels to be used for large-diameter cable reels, improvements were made based on Example 9, such as... Figure 1 and Figure 5-6 As shown, in this embodiment, the rotating component 1 further includes: a second cylindrical portion 13 and a second limiting member 14. The length of the second cylindrical portion 13 is less than the length of the first cylindrical portion 11, and the inner diameter of the second cylindrical portion 13 is greater than the outer diameter of the first cylindrical portion 11. The open end of the second cylindrical portion 13 passes through the second limiting member 14 and is connected to the second limiting member 14.

[0051] In practice, if the components of the first and second line-laying tools are not used interchangeably, the first line-laying tool can be used as follows: Figure 5 As shown, a reinforcing plate 223 is provided. If the base 22 in the first wire-laying tool needs to be used as the first limiting member 12 in the second wire-laying tool, then the first wire-laying tool is as follows: Figure 6 As shown, no reinforcing plate 223 is provided so that the cable reel can be supported on the aforementioned base 22. Since the first cable laying tool is intended for use with small-sized cable reels, the requirement can be met without the reinforcing plate 223. Furthermore, the rod 21 in the first cable laying tool is essentially the first cylindrical part 11 in the second cable laying tool. Although its structural strength is somewhat reduced compared to a solid rod 21, it is still sufficient for small-sized cable reels.

[0052] During use, after removing the support member 2 of the first wire-laying tool, the cylindrical rod 21 of the support member 2 is fitted onto the support member 2 of the second wire-laying tool and used as the rotating member 1 of the second wire-laying tool.

[0053] The cable laying tool provided by this utility model has a simple structure, requiring only the welding of steel and pipe materials. The entire structure does not use a single bearing, reducing manufacturing costs and making cable laying and winding operations more labor-saving and convenient, thus improving work efficiency. When the first cylindrical section 11 on the rotating component 1 is long enough, multiple cable reels can be threaded simultaneously, enabling the laying and winding of various types of cables.

[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
