Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying fixing device. Background Technology

[0002] Cables are typically made up of several or several groups of conductors (at least two conductors per group) twisted together around a central conductor. There are two ways to lay cables: overhead and underground. Overhead laying requires the cable to be supported and fixed to prevent long and heavy cables from being worn down by the wind due to lack of support when suspended at high altitudes for a long time, thus shortening their service life.

[0003] The existing cable laying fixing frame is generally fixed to the side wall of the cable trench, and then the bracket for fixing the cable extends laterally. The cable is laid on the bracket. When there are many cables, it is easy for them to cross and entangle, which will lead to misalignment in the later laying. Utility Model Content

It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] It should also be noted that, in this embodiment, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] See Figures 1-8A cable laying and fixing device includes: a support plate, on which an upper clamping plate 1 and a lower clamping plate 4 are detachably connected. The lower clamping plate 4 is located directly below the upper clamping plate 1. The upper clamping plate 1 has an upper sliding groove 2 at its bottom and a plurality of upper slots 3 at its top. The lower clamping plate 4 has a lower sliding groove 5 at its top and a plurality of lower slots 6 at its bottom. An upper slider 7 is slidably connected in the upper sliding groove 2 and a lower slider 8 is slidably connected in the lower sliding groove 5. Both the upper slider 7 and the lower slider 8 are connected to elastic clips. The upper slider 7 and the lower slider 8 are fixed to the upper clamping plate 1 and the lower clamping plate 4 respectively by inserting the elastic clips into the upper slots 3 and the lower slots 6. An upper clamping assembly is connected to the bottom of the upper slider 7 and a lower clamping assembly is connected to the top of the lower slider 8. The lower clamping assembly and the upper clamping assembly fix the cable.

[0047] It should be noted that the upper clamping plate 1 and the lower clamping plate 4 are detachably connected to the support plate. In use, multiple sets of upper clamping plates 1 and lower clamping plates 4 can be connected from top to bottom according to the number of layers of upper and lower cables. Alternatively, according to the number of cables in each layer, the same number of upper sliders 7 and lower sliders 8 can be connected to each set of upper clamping plates 1 and lower clamping plates 4.

[0048] For example, if there are three layers of cables, three sets of upper clamping plates 1 and lower clamping plates 4 can be connected to the support plate. According to the height of the three layers of cables, the three sets of upper clamping plates 1 and lower clamping plates 4 are connected to the support plate at appropriate positions. The diameter of the cables can be fixed as needed. The distance between each set of upper clamping plates 1 and lower clamping plates 4 can be adjusted on the support plate. If there are three cables in each layer, three upper sliders 7 and lower sliders 8 can be connected to each set of upper clamping plates 1 and lower clamping plates 4 respectively. The position of each set of upper sliders 7 and lower sliders 8 is adjusted on the upper clamping plates 1 and lower clamping plates 4 according to the position of each layer of cables, and fixed by elastic clips. The cables are clamped by the upper clamping components and lower clamping components of each set of upper sliders 7 and lower sliders 8 as needed.

[0049] It is worth noting that in this utility model, the number of upper clamping plates 1 and lower clamping plates 4 can be connected according to the number of cable layers. Furthermore, the number of upper sliders 7 and lower sliders 8 can be connected to each set of upper clamping plates 1 and lower clamping plates 4 according to the number of cables in each layer. This prevents cross-entanglement and other phenomena when there are many cables, thus preventing misalignment during subsequent laying.

[0050] Further, the support plate includes: a support plate body 9, with connecting plates 14 connected to both the upper and lower ends of the support plate body 9. The connecting plates 14 have second connecting holes 15, through which bolts pass and connect to the inner wall of the cable trench. A groove 10 is formed on the back of the support plate body 9, and an elongated through hole 11 is formed on the support plate body 9 within the groove 10. The size of the elongated through hole 11 is smaller than the size of the groove 10. Several first connecting holes 12 are formed within the groove 10, located on opposite sides of the elongated through hole 11. The several first connecting holes 12 are evenly spaced, with the spacing determined according to... To adjust the required precision, connecting blocks 13 are connected to the ends of both the upper clamping plate 1 and the lower clamping plate 4. The width of the upper clamping plate 1 and the lower clamping plate 4 is adapted to the width of the elongated through hole 11. The ends of the upper clamping plate 1 and the lower clamping plate 4 away from the connecting block 13 pass through the elongated through hole 11. The connecting block 13 contacts the groove 10 with the first connecting hole 12. After adjusting the position of the upper clamping plate 1 and the lower clamping plate 4, the connecting block 13 is fixed to the first connecting hole 12 with bolts. Through the structure of this support plate, it is convenient to connect the corresponding number of upper clamping plates 1 and lower clamping plates 4 according to the number of cable layers, and it is also convenient to adjust the position of the upper clamping plate 1 and the lower clamping plate 4.

[0051] Furthermore, the upper sliding groove 2 and the lower sliding groove 5 are T-shaped grooves, and the upper slider 7 and the lower slider 8 are T-shaped blocks that match the T-shaped grooves. The T-shaped grooves and T-shaped blocks enable smooth movement during sliding, reducing swaying or deviation caused by lateral forces and increasing stability.

[0052] In addition, the upper slide groove 2 and the lower slide groove 5 are respectively opened through the ends of the upper clamping plate 1 and the lower clamping plate 4 away from the connecting block 13, so that the upper slide block 7 and the lower slide block 8 can slide into or out of the upper slide groove 2 and the lower slide groove 5 respectively.

[0053] Furthermore, through holes are provided on the upper slider 7 and the lower slider 8, and elastic snap-fit ​​components are connected within the through holes. The elastic snap-fit ​​components include: a guide cylinder 16, which is connected within the through holes. The top of the guide cylinder 16 on the upper slider 7 is lower than the upper surface of the upper slider 7, and the bottom of the guide cylinder 16 on the lower slider 8 is higher than the lower surface of the lower slider 8. Limiting rings are connected to the inner walls of both the upper and lower ends of the guide cylinder 16. A sliding rod 18 is slidably connected inside the guide cylinder 16, and the diameter of the sliding rod 18 matches the inner diameter of the limiting rings. An upper limit plate 19 is connected to the side wall of the sliding rod 18. The limiting plate 19 has an annular structure, with its inner wall connected to the side wall of the sliding rod 18. Its outer diameter matches the inner diameter of the guide cylinder 16. A lower limiting plate 17 is connected inside the guide cylinder 16. The lower limiting plate 17 has an annular structure, with its outer wall fixed to the inner wall of the guide cylinder 16. The inner diameter of the lower limiting plate 17 matches the diameter of the sliding rod 18. The lower limiting plate 17 is located below the upper limiting plate 19. The lower limiting plate 17 and the upper limiting plate 19 are located between the limiting rings at the upper and lower ends of the guide cylinder 16. A spring 20 is sleeved on the sliding rod 18, and the spring 20 is located between the lower limiting plate 17 and the upper limiting plate 19.

[0054] When the spring 20 is not under force, the upper end of the sliding rod 18 is located outside the guide cylinder 16. A pull rod 21 is connected to the lower end of the sliding rod 18. In use, the sliding rod 18 is pulled down or up by the pull rod 21 to compress the spring 20. The upper or lower end of the sliding rod 18 enters the guide cylinder 16. The upper slider 7 and the lower slider 8 can slide in the upper slide groove 2 and the lower slide groove 5. The positions of the upper slot 3 and the lower slot 6 in the upper slide groove 2 and the lower slide groove 5 correspond to the positions of the sliding rod 18. The upper slot 3 and the lower slot 6 are equally spaced, and the spacing is set according to the adjustment accuracy requirements. When the upper slider 7 and the lower slider 8 slide to the position to be installed, the pull rod 21 is released, the spring 20 extends, and pushes the sliding rod 18 so that its upper or lower end enters the corresponding upper slot 3 or lower slot 6.

[0055] The above structure allows for the connection of a corresponding number of upper sliders 7 and lower sliders 8 to the upper clamping plate 1 and lower clamping plate 4 based on the number of cables in each layer. Furthermore, the positions of the upper sliders 7 and lower sliders 8 on the upper clamping plate 1 and lower clamping plate 4 can be adjusted according to the position of each cable, making the use more flexible.

[0056] Furthermore, the lower clamping assembly includes a lower clamping plate 22, which is connected to the top of the lower slider 8, and the top of the lower clamping plate 22 is provided with a lower arc-shaped groove 23. The upper clamping assembly includes a sliding hole 24, which is opened on the top of the upper clamping plate 1. The sliding hole 24 is opened through the end of the upper clamping plate 1 away from the connecting block 13, and its width is less than the width of the upper sliding groove 2. The length of the sliding hole 24 is the same as the length of the upper sliding groove 2. A threaded hole is opened through the upper slider 7, and a screw 25 is threadedly connected to the threaded hole. The upper end of the screw 25 is located outside the upper clamping plate 1 through the sliding hole 24, and a rotating handle 28 is connected to this end. The lower end of the screw 25 is located outside the upper clamping plate 1 through the bottom opening of the upper sliding groove 2, and the lower end is rotatably connected to the upper clamping plate 26 through a bearing. The bottom of the upper clamping plate 26 is provided with an upper arc-shaped groove 27, which clamps the cable between the upper arc-shaped groove 27 of the upper clamping plate 26 and the lower arc-shaped groove 23 of the lower clamping plate 22.

[0057] The diameter of the cable can be fixed as needed. The distance between each set of upper clamping plate 1 and lower clamping plate 4 can be adjusted over a wide range on the support plate. Then, fine adjustments can be made by turning the screw 25. The distance between the upper clamping plate 26 and the lower clamping plate 22 can be adjusted by adjusting the cable diameter to adjust the appropriate clamping force.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
