Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable protection support, in particular to a multifunctional closed light cable support bracket. BACKGROUND

[0002] Metal cable support bracket (especially steel and aluminum alloy), as the core support component of power, communication and integrated wiring system, is widely used in cable laying engineering of various buildings and industrial facilities to bear, fix and protect the cable, because of its excellent structural bearing capacity, reliable physical and chemical stability (corrosion resistance, fireproof), precise geometric shape and mature manufacturing process, and undertakes the key task of safely and orderly supporting, positioning and protecting the cable system.

[0003] In the technical evolution process of cable support bracket, how to balance the structure efficiency (bearing capacity, stability) and the efficiency and flexibility of construction and installation has always been an important core and a significant feature driving its development. Although the early common open angle steel support has simple structure and reliable strength, its bearing capacity is relatively limited, and it needs to be welded or drilled on site during installation, which is complicated and has insufficient adaptability. The subsequently popularized stamping steel bridge and supporting arm system, although realizing modular combination and welding-free installation, significantly improving the construction speed, its open support bracket has limited bending and torsional resistance, and the multi-hole stamping bridge further weakens the bending and torsional stiffness performance.

[0004] In view of this problem, the engineering and academic circles at home and abroad have carried out extensive research, and the patent CN221177156U proposes a light cable support design, which aims to facilitate height adjustment, but the structure itself is too complicated, and the steps of assembling and maintaining the structure are complex during on-site construction, which also affects the stability of the support; the patent CN216851183U proposes a cable support design with adjustable height, which uses a threaded rod to achieve height adjustment, and the overall structure uses a large number of bolts, which can ensure rigidity and stability, but puts forward higher requirements for construction and maintenance; the patent CN205231653U proposes a combined cable support without disconnection, which can only adjust the height in a limited position, although it avoids using too many bolt connections; the patent US201013393292A proposes a triangular section design with side openings, which solves some installation problems, but has low functional expansion and weak torsional stiffness when used in cable supports. The above cable support designs have the following shortcomings: (1) complicated design and complex structure, which puts forward too high requirements for construction and maintenance; (2) poor structural rigidity and limited bearing capacity; (3) insufficient adaptability to the use environment, which can only adjust the height in a fixed and limited position, and it is difficult to adjust the overall structure width, so it cannot be applied to various construction sites; (4) single function, which requires additional processing to add accessories to realize functional expansion in actual application scenarios. SUMMARY

[0005] The purpose of the present application is to provide a multifunctional closed light cable support, which aims to design a new type of cable support that takes into account rigidity, stability and construction convenience. It can ensure that there is no large deflection deformation and strength failure in working conditions, and compared with existing construction procedures, it can more quickly realize the connection and relative position adjustment between parts, so as to solve the problem that the construction convenience and reliability of existing cable supports are difficult to balance.

[0006] To achieve the above purpose, the present application provides a multifunctional closed light cable support, which comprises a first short right angle edge, a second short right angle edge, a first long right angle edge, a second long right angle edge and a bevel edge. The first short right angle edge and the second long right angle edge are arranged in parallel, and the second short right angle edge and the first long right angle edge are arranged in parallel. The second long right angle edge, the second short right angle edge, the bevel edge, the first short right angle edge and the first long right angle edge are arranged clockwise, and the cross section formed thereby is a rectangle with one corner cut off.

[0007] Preferably, the second long right angle edge and the second short right angle edge are connected at the interface, the second short right angle edge and the bevel edge are connected at the interface, the bevel edge and the first short right angle edge are connected at the interface, and the first short right angle edge and the first long right angle edge are connected at the interface. The interface between the first long right angle edge and the second long right angle edge is connected by welding.

[0008] Preferably, at least one of the first long right-angled side and the second long right-angled side has a bolt hole, and the hypotenuse has a bolt inlet hole.

[0009] Preferably, the bolt holes of the first long right-angle side and the second long right-angle side and the bolt inlet hole of the inclined side are prefabricated in the flat plate stage before bending and forming, and the opening axis of the bolt hole and the bolt inlet hole is parallel to the axial direction of the cable support.

[0010] Preferably, the width of the first short right-angled side and the second short right-angled side is 1.1-1.5 times that of the other sides, and the first short right-angled side and the second short right-angled side may or may not have holes.

[0011] Preferably, the bolt holes are elliptical or rectangular in shape and are arranged parallel to the axial direction of the cable support.

[0012] Preferably, when bolt holes are provided on both the first long right-angle side and the second long right-angle side, the bolt inlet hole corresponds spatially with the bolt hole in the axial direction of the support, so that the bolt can pass through the bolt inlet hole without interference, and the support can be installed on the structure to be fixed through the bolt hole on the right-angle side of the support.

[0013] Therefore, the present invention employs the above-mentioned multifunctional closed-type lightweight cable support, which has the following beneficial effects: 1. Improved ease of construction: This invention eliminates the need for on-site drilling required for traditional cable supports without pre-drilled holes. Bolt positioning is achieved through the alignment of bolt holes and bolt lead-in holes, significantly improving the assembly efficiency of cable supports and reducing construction costs.

[0014] 2. Excellent mechanical properties: The improved design of this invention possesses high bending stiffness and sufficient torsional stiffness, effectively resisting large deflection and torsional deformation. In the cross-sectional design, the first and second short right-angled sides effectively enhance bending stiffness, while the closed cross-section design ensures torsional stiffness; when applied to cable supports, it effectively improves the overall reliability of the structure.

[0015] 3. Good production adaptability: The manufacturing process of this invention is simple, and the design can be modified with minor modifications to the existing production line (such as adding a hole-opening process), resulting in low production line modification costs; when using this for cable support and hanger construction, the number of compatible parts required is small, effectively improving the adaptability of the complete set of equipment.

[0016] 4. High functional expandability: By selectively opening bolt holes of limited size on the first short right angle side and the second short right angle, this invention can provide convenient auxiliary connection points for installing lightweight auxiliary components (such as signal line brackets, sensor brackets, etc.) while ensuring the main rigidity. At the same time, it provides more options for the connection and fixing methods between the plate and the beam, further expanding the functional adaptability of the support.

[0017] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] The following detailed description of embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] Please see Figure 1A multifunctional closed-type lightweight cable support includes a first short right-angled side 4, a second short right-angled side 5, a first long right-angled side 2, a second long right-angled side 3, and a hypotenuse 1; the first short right-angled side 4 is parallel to the second long right-angled side 3, and the second short right-angled side 5 is parallel to the first long right-angled side 2; the second long right-angled side 3, the second short right-angled side 5, the hypotenuse 1, the first short right-angled side 4, and the first long right-angled side 2 are arranged clockwise around each other, forming a cross-section with one corner truncated. The rectangle is formed by bending at the junctions of the second longer right-angled side 3 and the second shorter right-angled side 5, the junction of the second shorter right-angled side 5 and the hypotenuse 1, the junction of the hypotenuse 1 and the first shorter right-angled side 4, and the junction of the first shorter right-angled side 4 and the first longer right-angled side 2. The junctions of the first longer right-angled side 2 and the second longer right-angled side 3 are connected by welding. At least one side of the first longer right-angled side 2 and the second longer right-angled side 3 has a bolt hole 7, and the hypotenuse 1 has a bolt inlet hole 8 for bolt introduction. Hole 8 is elliptical or rectangular in shape. The bolt inlet hole 8 is parallel to the axial direction of the cable support. When bolt holes 7 are provided on both the first long right-angled side 2 and the second long right-angled side 3, the bolt inlet hole 8 spatially corresponds to the bolt hole 7 in the length direction, allowing the bolt to pass through the bolt inlet hole 8 without interference. The support is then installed on the structure to be fixed via the bolt holes 7 on the right-angled sides 2 and 3. The bolt holes 7 and bolt inlet holes 8 are prefabricated in the flat plate stage before bending and forming, and the opening axis is parallel to the axial direction of the cable support. The thickness of the first short right-angled side 4 and the second short right-angled side 5 is 1.1-1.5 times that of the other sides. The first short right-angled side 4 and the second short right-angled side 5 can be optionally perforated. When perforated, the corresponding bolt holes are used to enhance the stability of the support installation and, in special circumstances, provide optional side mounting positions. This also provides installation possibilities for optional auxiliary components.

[0021] Example 1 like Figure 2 and Figure 3 The processing method for cable supports is as follows: First, pre-drill bolt holes and bolt inlet holes in the flat plate stage, ensuring that the hole axis is parallel to the axial direction of the cable support; then, shape the plate into a rectangle with a truncated corner through bending, rolling, and other processes; finally, complete the closed section connection by welding at the intersection of the first and second long right-angled sides. If the bolt inlet holes are arranged in a single row, a half-hole punching process can be used during punching, or the holes can be cut along the long axis of the hole after punching; if lightweight auxiliary components (such as purlin connecting plates, pipeline supports, etc.) need to be installed, bolt holes can be made on the first and second short right-angled sides. The hole diameter should not exceed 30% of the length of the short right-angled side, and they should be evenly spaced along the length direction at a spacing of not less than 8 times the hole diameter, and at least 50 mm from the apex of the truncated corner to avoid the area of ​​stress concentration due to bending of the cross section. This design expands the auxiliary connection function while maximizing the stiffness enhancement effect of the short right-angled sides.

[0022] like Figure 4 As shown, the specific assembly method of the processed cable support is as follows: The column and the beam are connected by bolts. During installation, first, the bolt head is inserted into the beam cavity through the bolt guide hole 7 on the inclined side of the column; adjust the posture of the bolt shank so that it passes through the corresponding bolt holes on the first and second long right-angled sides. The rectangular long axis of the bolt hole is along the length of the beam, forming a guide channel that allows the bolt to slide axially. After the bolt passes through, its end extends into the corresponding bolt hole on the long right-angled side of the beam (as a mating hole), and finally the nut is tightened to complete the rigid connection.

[0023] The connection method between the crossbeam 6 and the crossbeam is similar, and there are four connection methods: First, the first component 9 is used to fix the crossbeam by passing through the bolt holes on the crossbeam and the bolt holes on the second long right-angle side; second, the crossbeam is connected to the side of the crossbeam by the second component 10 through bolt holes on the second short right-angle side; third, the bolt holes on the second long right-angle side are connected to the bolt holes on the side of the crossbeam by the third component 11; fourth, the surface of the crossbeam is connected to the second short right-angle side by the fourth component 12, as detailed below. Figure 5 As shown.

[0024] For columns and beams with bolt holes on the first or second short right-angle side, various lightweight accessories, such as signal cable brackets and sensor brackets, can be installed through these holes, thereby expanding the function of the support and supporting various plate-beam connection methods.

[0025] Example 2 like Figure 6 OGL triangular support section and Figure 7 The cross-section of the multifunctional closed-type lightweight cable support is shown below: For the OGL triangular support cross-section, the in-plane point 18.75mm from both the first and second longest right-angled sides is taken as the origin of the output coordinate system. This makes the origin coincide with the centroid of the cross-section. The x-axis is parallel to the first longest right-angled side, and the y-axis is parallel to the second longest right-angled side, thus constructing the output coordinate system. For the multifunctional closed-type lightweight cable support cross-section, the in-plane point 20.79mm from both the first and second longest right-angled sides is taken as the origin of the output coordinate system. This makes the origin coincide with the centroid of the cross-section. The x-axis is parallel to the first longest right-angled side, and the y-axis is parallel to the second longest right-angled side, thus constructing the output coordinate system. Through relevant calculations under this output coordinate system, it can be proven that the bending stiffness and torsional stiffness of the present invention are both increased by at least 20% compared with the traditional triangular cross-section. Specific experimental evidence is as follows: Select the cross-sectional properties of the 50×50 selected surface of the OGL triangular support, and then calculate the corresponding bending strength and torsional strength. The elastic modulus of the material used is known to be E=210GPa and the shear modulus to be G=79.4GPa, as detailed below: OGL triangular support 50×50 selected surface section properties in the output coordinate system region moment of inertia: (mm) 4 ) ; In the formula, I xx I represents the moment of inertia of the cross section about the x-axis of the coordinate system shown. yy Let J represent the moment of inertia of the cross section about the y-axis of the coordinate system shown, and let J represent the rotational moment of inertia of the cross section about the origin of the coordinate system shown.

[0026] Its corresponding bending stiffness is: , The torsional stiffness is: The cross-sectional properties of the selected surface of the 50×50 multi-functional closed lightweight cable support in the output coordinate system: (mm) 4 ) ; Its corresponding bending stiffness is: , The torsional stiffness is: The results of comparing the traditional design scheme (triangular support) with the multifunctional new design scheme of this application are shown in Table 1 below. Table 1

[0027] As shown in Table 1 above, the bending stiffness increased by more than 37%, and the torsional stiffness increased by more than 23%.

[0028] Example 3 like Figure 8 OGL triangular support section and Figure 9The cross-section of the multifunctional closed-type lightweight cable support is shown below: For the OGL triangular support cross-section, the in-plane point 36.25mm from both the first and second longest right-angled sides is taken as the origin of the output coordinate system. This makes the origin coincide with the centroid of the cross-section. The x-axis is parallel to the first longest right-angled side, and the y-axis is parallel to the second longest right-angled side, thus constructing the output coordinate system. For the multifunctional closed-type lightweight cable support cross-section, the in-plane point 38.64mm from both the first and second longest right-angled sides is taken as the origin of the output coordinate system. This makes the origin coincide with the centroid of the cross-section. The x-axis is parallel to the first longest right-angled side, and the y-axis is parallel to the second longest right-angled side, thus constructing the output coordinate system. Through relevant calculations under this output coordinate system, it can also be proven that the bending stiffness and torsional stiffness of the present invention are increased by at least 20% compared with the traditional triangular cross-section. Specific experimental evidence is as follows: Select the cross-sectional properties of the 100×100 selected surface of the OGL triangular support, and then calculate the corresponding bending strength and torsional strength. The material's elastic modulus is known to be E=210GPa and shear modulus to be G=79.4GPa, as detailed below: OGL triangular support 100×100 selected surface section properties in the output coordinate system regional moment of inertia: (mm) 4 ) ; Its corresponding bending stiffness is: , The torsional stiffness is: The cross-sectional properties of the selected surface of the 100×100 multi-functional closed lightweight cable support in the output coordinate system are: Regional moment of inertia: (mm) 4 ) ; Its corresponding bending stiffness is: , The torsional stiffness is: The results of comparing the traditional design scheme (triangular support) with the multifunctional new design scheme of this application are shown in Table 2 below. Table 2

[0029] As shown in Table 2 above, the bending stiffness increased by more than 32.68%, and the torsional stiffness also increased by more than 32.68%.

[0030] Therefore, the present invention adopts the above-mentioned multifunctional closed lightweight cable support bracket, in which the second long right-angled side, the second short right-angled side, the hypotenuse, the first short right-angled side, and the first long right-angled side are arranged clockwise to form a cross-section that is a square with one corner cut off; and welding is only performed at the junction of the first long right-angled side and the second long right-angled side, while the other junctions are bent, thereby enabling the cable support bracket to have high bending stiffness and sufficient torsional stiffness, so as to effectively resist large deflection deformation and torsional deformation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
