Description

Technical Field

[0001] The present application relates to a cable support. Background Art

[0002] Currently, cable supports are usually made of composite sheets by fiber-reinforced resin and then obtained by molding. Due to advantages such as corrosion resistance, light weight, high strength, and no current loss, cable supports have great advantages compared with traditional galvanized angle steel cable supports. Cable supports are also increasingly applied to power grid construction.

[0003] As is well known, cable supports, as a building material for carrying cables, can fix the position of cables, regularize the cable routing, and avoid damage to cables caused by environmental factors, which is of great significance for cable laying work and is often used in underground pipe galleries, subway tunnels, and cable trenches. In recent years, the country has vigorously promoted the construction of power pipe galleries and cable trenches for the goals of enhancing the reliability of the national power grid and power transmission capacity, as well as the development direction of beautifying the city, which means that the market demand for cable supports is also increasing. With the advancement of underground power grid construction work, the installation environment is becoming more and more diverse, and the terrain has more and more requirements for cable supports. Usually, cables should be laid on the same horizontal line to avoid cable movement due to gravity or stress concentration resulting in cable damage. However, the slope or curvature of the construction site or installation surface makes the installation preparation of cable supports cumbersome; for the same site environment, multiple cable support designs are often required; even after some cable supports are installed, it hinders subsequent construction access and cable inspection. Therefore, it is very meaningful to design a cable support with a flexible movable structure. Summary of the Invention

[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0051] To enable those skilled in the art of the present technology to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific embodiments.

[0052] The cable support provided by this application refers to the attached Figure 1 to the attached Figure 11 and includes: a substrate 1, a rotating shaft assembly 2, a towing arm 3, and a support assembly 4; wherein, the substrate 1 is used for installation in the first direction, and the first direction can specifically be the vertical direction, the substrate 1 is vertically arranged, that is, the substrate 1 can be fixed on a vertical installation surface. The substrate 1 can be formed by composite material molding, and a fitting hole 14 can be provided at a position near the edge of the substrate 1, and the fitting hole 14 is used to fix the substrate 1 on the installation surface.

[0053] The rotating shaft assembly 2 is rotatably arranged on the substrate 1, and the rotation axis of the rotating shaft assembly 2 is parallel to the first direction; that is, the rotation axis of the rotating shaft assembly 2 can also be the vertical direction.

[0054] The towing arm 3 is rotatably arranged on the rotating shaft assembly 2, the towing arm 3 extends in the second direction, and the second direction can specifically be the horizontal direction extending away from the substrate 1, the towing arm 3 is used to support the cable, and the rotation axis of the towing arm 3 extends in the third direction; the third direction can be perpendicular to the first direction and the second direction, that is, the first direction, the second direction, and the third direction can be perpendicular to each other in pairs, and the towing arm 3 can be formed by composite material molding.

[0055] The support assembly 4 is telescopically arranged, and both ends of the support assembly 4 are respectively connected to the substrate 1 and the towing arm 3, and the support assembly 4 is used to support the towing arm 3.

[0056] Under the action of the rotating shaft assembly 2 and the support assembly 4, the towing arm 3 can rotate at two angles, so as to adjust the position of the towing arm 3 relative to the substrate 1 or the installation surface.

[0057] In one embodiment, the rotating shaft assembly 2 includes two semi - shafts 21, each semi - shaft 21 is provided with a through - hole 211 and a groove 212, the through - hole 211 and the groove 212 are opened along the second direction, after the two semi - shafts 21 are spliced, the two grooves 212 form a receiving cavity 213, and the two through - holes 211 are respectively located on both sides of the receiving cavity 213 in the third direction.

[0058] The towing arm 3 includes: a rotating body 31, a shaft body 32, and an arm frame 33, the rotating body 31 is received in the receiving cavity 213; the shaft body 32 is arranged on both sides of the rotating body 31 in the third direction, and the shaft body 32 is rotatably arranged in the through - hole 211; the arm frame 33 is arranged on the rotating body 31 and extends along the second direction, and is used to support the cable.

[0059] During installation, the two semicircular shafts 21 are respectively installed on both sides of the rotating body 31. When the two semicircular shafts 21 are fitted into place, that is, when the two semicircular shafts 21 are installed, the accommodating cavity 213 formed by the two grooves 212 is accommodated in the accommodating cavity 213. At the same time, the two shaft bodies 32 are respectively matched with different through holes 211. The shaft bodies 32 can rotate relative to the through holes 211, so that the rotating body 31 rotates in the accommodating cavity 213. In this way, the pitch angle of the arm 33 relative to the substrate 1 can be adjusted to adapt to different occasions.

[0060] The rotational connection method between the rotating shaft assembly 2 and the trailing arm 3 should not be limited to the specific implementation described in this article. It is foreseeable that in order to achieve the pitch angle adjustment of the trailing arm 3 relative to the rotating shaft assembly 2, other different structures can also be used.

[0061] Regarding the specific structure of the rotating shaft assembly 2, in a specific embodiment, the rotating shaft assembly 2 also includes: a shaft head 22 and a shaft cover 23, the shaft head 22 is arranged at both ends of the semicircular shaft 21 in the first direction; the shaft cover 23 is arranged at both ends of the semicircular shaft 21 in the first direction, wherein the shaft cover 23 includes: a cover plate 231 and a snap-fit body 232, the cover plate 231 is provided with a mounting hole 2311, and the mounting hole 2311 is used to sleeve the shaft head 22; the snap-fit body 232 is arranged on the cover plate 231, and the snap-fit body 232 extends along the first direction, and is used to fit with the outer sides of the two semicircular shafts 21 to avoid separation of the two semicircular shafts 21.

[0062] Instructions attached Figure 2 Taking the position shown as an example, for each semicircular shaft 21, shaft heads 22 are provided at both ends, and the two shaft heads 22 can be spliced into a cylinder. The shape and size of the mounting hole 2311 match the spliced cylinder, and the mounting hole 2311 can be used to limit the two shaft heads 22; the buckle body 232 is used to limit the two semicircular shafts 21 to prevent the two semicircular shafts 21 from separating. Of course, the installation and limiting method of the two semicircular shafts 21 can also be connected by means of buckles, etc., to ensure that the positions of the two semicircular shafts 21 are fixed reliably.

[0063] The cover plate 231 and the semicircular shaft 21 may also be provided with corresponding assembly holes 24 so that fasteners can fix the cover plate 231 and the semicircular shaft 21 through the assembly holes 24. Two cover plates 231 may be provided, respectively located at the upper and lower ends of the semicircular shaft 21. In this way, the two semicircular shafts 21 and the two cover plates 231 are kept in fixed position by multiple fasteners to avoid disintegration of the rotating shaft assembly 2 during use.

[0064] In a specific embodiment, the substrate 1 is provided with a support 11. The support 11 extends in the second direction and is used for rotatably connecting the shaft head 22. Of course, in order to reduce the space occupation, an avoidance groove 12 can also be provided on the substrate 1. The position of the avoidance groove 12 matches the position of the rotating shaft assembly 2. Part of the structure of the rotating shaft assembly 2 is accommodated in the avoidance groove 12. The two supports 11 are respectively located at both ends of the length direction of the avoidance groove 12. In this way, when the rotating shaft assembly 2 rotates, the substrate 1 will not interfere.

[0065] In a specific embodiment, the support assembly 4 may include: a first rod 41 and a second rod 42. The first rod 41 is connected to the substrate 1; both ends of the second rod 42 are respectively connected to the first rod 41 and the trailing arm 3. One of the first rod 41 and the second rod 42 is provided with a plurality of adjustment holes 43 arranged along the length direction, and the other is provided with a locking hole 44 that is selectively coaxial with one of the adjustment holes 43. After the locking hole 44 and one adjustment hole 43 are coaxially aligned, the locking hole 44 and the adjustment hole 43 are connected by a locking part.

[0066] Specification appendix Figure 8 And appendix Figure 9 The situation where a plurality of adjustment holes 43 are provided in the first rod 41 is shown. Correspondingly, the locking hole 44 should be provided in the second rod 42. The locking hole 44 is located at one end of the second rod 42. A connection hole 46 can be provided at the other end of the second rod 42 and used to connect with the trailing arm 3. Both the first rod 41 and the second rod 42 can be formed by composite material molding.

[0067] It can be seen that when the locking hole 44 is connected and matched with different adjustment holes 43, it can be considered that the first rod 41 and the second rod 42 are telescoped, thereby adjusting the pitching angle of the trailing arm 3. Obviously, the first rod 41 and the second rod 42 should be rotatably connected. Of course, in order to realize the telescoping of the support assembly 4, components such as piston cylinders can also be used, which will not be elaborated herein.

[0068] The support assembly 4 further includes a panel 45. The panel 45 is connected to the substrate 1 and is angularly connected to the end of the first rod 41; the panel 45 is arranged on the side of the trailing arm 3 facing away from the cable. The panel 45 and the first rod 41 can be integrally provided. The panel 45 can be provided with fixing holes 451. Correspondingly, the substrate 1 is provided with through holes 13. During installation, the fixing holes 451 and the through holes 13 are coaxially aligned, and the fixing holes 451 and the through holes 13 are connected by using components such as bolts, so as to realize the fixed connection between the panel 45 and the substrate 1.

[0069] In order to ensure that the structure of the support assembly 4 is stable and reliable, the number of the second rods 42 can be set to two, and the two second rods 42 are respectively arranged on both sides of the first rod 41, and the trailing arm 3 is provided with a fixing through hole 30, and the two second rods 42 are respectively connected to the fixing through holes 30. It can be seen that the two second rods 42 are not only located on both sides of the first rod 41, but also on both sides of the trailing arm 3. After the connection hole 46 of the second rod 42 and the fixing through hole 30 are matched, bolts and other components can be used for hinge connection, so that the second rod 42 and the trailing arm 3 are rotatably connected. Obviously, the second rod 42 and the first rod 41 are also rotatably connected.

[0070] The trailing arm 3 is provided with a plurality of supporting grooves 34 arranged in sequence along the second direction, and the supporting grooves 34 are used to support the cables; Figure 1 As shown, a plurality of supporting grooves 34 are provided on the upper surface of the trailing arm 3 , and each supporting groove 34 can support different cables, so that one trailing arm 3 can be used to support different cables.

[0071] An anti-slip portion 35 is provided at the end of the trailing arm 3 facing away from the base plate 1, and the anti-slip portion 35 extends along the first direction. One end of the trailing arm 3 is rotatably connected to the rotating shaft assembly 2, and the other end of the trailing arm 3 is provided with an anti-slip portion 35, which is used to prevent the cable from jumping out of the end of the trailing arm 3.

[0072] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0073] The cable bracket provided by the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
