Description

Technical Field

[0001] This utility model relates to the field of cable tray support technology, specifically a cable tray support arm. Background Technology

[0002] Cable tray supports are an important component of cable tray systems. They primarily support the cable trays, ensuring their stable installation on buildings or other structures and providing reliable support for cable laying. Simply put, they act like an "arm," lifting the cable trays to maintain a certain distance from the ground or other facilities, facilitating cable installation and management.

[0003] During installation, first align the edge of the cable tray with the slot of the bracket, and then slowly place the cable tray on the bracket so that the bottom edge of the cable tray is fully embedded in the slot. However, the above fixing method is based on the connection between the cable tray and the bracket, and has poor adaptability to different sizes of cables. It mainly provides support for the cable tray and does not have an adaptive mechanism for changes in the size of the cable tray itself. If different sizes of cables are replaced, the above fixing method cannot adapt well to changes in the size of the cable tray. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray support arm to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a cable tray support arm, including a column body, a support arm body fixedly installed on the column body, the cross-section of the support arm body being trapezoidal; two arc-shaped plates fixedly installed on the top of the support arm body, the bending directions of the two arc-shaped plates being opposite; a reset plate fixedly installed on the top of the support arm body, the cross-section of the reset plate being L-shaped, the vertical surface of the reset plate being fixedly connected to the arc-shaped outer wall of the arc-shaped plate; and a connecting plate fixedly installed on the top of the reset plate, the side of the connecting plate away from the reset plate being fixedly installed on the arc-shaped outer wall of the arc-shaped plate.

[0006] Furthermore, when a guide plate is fixedly installed on the top of the arc-shaped plate, the number of guide plates is set to two, and the two guide plates are symmetrically inclined.

[0007] Furthermore, a support rod is fixedly installed on the outer wall of the column body, and the other end of the support rod is fixedly installed on the bottom of the support arm body, forming a triangle between the column body, the support arm body, and the support rod.

[0008] Furthermore, the vertical cross-section of the column body is convex, and multiple positioning bolts are equidistantly threaded onto the column body.

[0009] Furthermore, a column top plate is fixedly installed on the top of the column body, and screw holes are evenly opened at the four corners of the column top plate.

[0010] Furthermore, the guide plate, reset plate, and connecting plate are all made of spring steel.

[0011] Furthermore, the support arm body and the support rod are made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the worker opens one of the guide plates, and the cable tray is placed smoothly between two oppositely bent arc-shaped plates along the inclined surface of the other guide plate. The cable tray causes the arc-shaped plates to open outward, and the connected L-shaped reset plate deforms, reducing the included angle. Because the arc-shaped plates and the reset plate are made of spring steel, they are elastic. After the cable tray is in place, the arc-shaped plates elastically reset and fix the cable tray, and the reset plate also elastically restores the included angle to its original state, assisting the arc-shaped plates in resetting. The arc-shaped plates are semi-enclosed around the cable tray, enhancing the fixing and clamping effect, ensuring the cable tray is laid and operated stably and safely. Moreover, depending on the size of the cable tray, the arc-shaped plates can be opened to different degrees and automatically reset and fix, adapting to the fixing needs of different sized cable trays.

[0014] 2. In this utility model, the two symmetrically inclined guide plates 5 provide a clear guiding direction for cable tray installation. When the cable tray is placed on the cable tray support arm, the cable tray can smoothly enter the appropriate position of the cable tray along the inclination direction of the guide plates 5.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] See Figures 1-4 As shown, a cable tray support arm includes a column body 2, a support arm body 3 fixedly installed on the column body 2, the cross-section of the support arm body 3 being trapezoidal; two arc-shaped plates 4 fixedly installed on the top of the support arm body 3, the bending directions of the two arc-shaped plates 4 being opposite; a reset plate 6 fixedly installed on the top of the support arm body 3, the cross-section of the reset plate 6 being L-shaped, the vertical surface of the reset plate 6 being fixedly connected to the arc-shaped outer wall of the arc-shaped plate 4; and a connecting plate 7 fixedly installed on the top of the reset plate 6, the side of the connecting plate 7 away from the reset plate 6 being fixedly installed on the arc-shaped outer wall of the arc-shaped plate 4.

[0023] During the operation of the cable tray support arm, the worker slightly opens one of the guide plates 5, and the cable tray is smoothly placed between two relatively bent arc-shaped plates 4 along the inclined surface of the other guide plate 5. During this process, the cable tray applies force to the arc-shaped plates 4, causing them to expand outwards on both sides. Simultaneously, the reset plate 6, fixedly connected to the arc-shaped outer wall of the arc-shaped plate 4, undergoes corresponding L-shaped deformation, meaning the angle between its vertical and horizontal surfaces decreases. Since both the arc-shaped plates 4 and the reset plate 6 are made of spring steel, possessing good elasticity, once the cable tray is fully positioned between the two arc-shaped plates 4, the arc-shaped plates 4 automatically reset due to their own elasticity, thus effectively fixing the cable tray. At the same time, under the elastic action of the spring steel, the angle between the vertical and horizontal surfaces of the reset plate 6 gradually increases and returns to its original state. Through this synergistic effect, the reset plate 6 effectively assists the arc-shaped plates 4 in completing the reset operation. At this point, the arc-shaped plate 4 forms a semi-enclosed shape around the cable tray, significantly enhancing the fixing and clamping effect, making it more stable and reliable. This effectively ensures the secure installation and safe operation of the cable tray on the tray support arm. Simultaneously, the elastic deformation of the arc-shaped plate 4 and the reset plate 6 adapts to the size of the cable tray. When the cable tray size is different, the arc-shaped plate 4 can expand to different degrees according to the size of the cable tray, and then automatically reset and fix itself, better adapting to the fixing needs of cable trays of different sizes.

[0024] See Figure 1-3When a guide plate 5 is fixedly installed on the top of the arc plate 4, the number of guide plates 5 is set to two, and the two guide plates 5 are symmetrically inclined.

[0025] Two symmetrically inclined guide plates 5 provide a clear guiding direction for cable tray installation. When placing the cable tray onto the cable tray support arm, the cable tray can smoothly enter the appropriate position along the inclination direction of the guide plates 5.

[0026] See Figure 1 A support rod 9 is fixedly installed on the outer wall of the column body 2. The other end of the support rod 9 is fixedly installed on the bottom of the support arm body 3. The column body 2, the support arm body 3, and the support rod 9 form a triangle.

[0027] The column body 2, the support arm body 3, and the support rod 9 form a triangular structure, which utilizes the principle of triangle stability. In geometric structures, a triangle is the most stable shape. Its three sides restrain each other, and when subjected to external forces, it can effectively resist deformation. For example, when the cable tray support arm bears the weight of the cable and the cable tray, or is subjected to external forces such as vibration and wind, this triangular structure can keep the support arm stable and prevent the support arm body 3 from excessively tilting, swaying, or twisting.

[0028] See Figure 1 The vertical section of the column body 2 is convex, and multiple positioning bolts 8 are connected by threads at equal intervals on the column body 2.

[0029] The vertical cross-section of the column body 2 is convex, which provides better bending resistance in terms of mechanical structure. When the cable tray support arm is subjected to external forces perpendicular to the column direction, such as bending moments caused by the weight of the cables or lateral wind loads, the convex shape of the column can effectively resist bending deformation. Compared to a simple column structure, the convex shape can provide a larger moment of inertia, resulting in less deformation of the column when subjected to the same external force. For example, in outdoor environments, if strong winds occur, the lateral force generated by the wind on the cable tray is transferred to the column through the support arm. The convex shape of the column can better maintain its stability, ensuring the safety of the cable tray system.

[0030] Multiple locating bolts 8 connected by equidistant threads can enhance the connection strength between the column body 2 and the mounting surface, such as building walls or the ground. By tightening the locating bolts 8, the column can be tightly fitted to the mounting surface, preventing the column from loosening or shifting during use. For example, in areas with frequent seismic activity, this robust connection method can effectively resist the impact of seismic waves on the cable tray support arm and reduce safety hazards caused by column loosening.

[0031] See Figure 1-3The top of the column body 2 is fixedly installed with a column top plate 1, and screw holes 10 are evenly opened at the four corners of the column top plate 1.

[0032] The screw holes 10 at the four corners of the column top plate 1 provide clear and convenient installation interfaces for connecting the cable tray support arm to other components such as the cable tray body or other supporting structures. By using screws or other connectors, the cable tray or other related components can be securely fixed to the column top plate 1. For example, when installing the cable tray, construction workers can directly align the bottom frame of the cable tray with the screw holes 10 on the column top plate 1 and tighten it with appropriate screws. This installation method is simple and direct, improving installation efficiency.

[0033] See Figure 1-4 The guide plate 5, reset plate 6, and connecting plate 7 are all made of spring steel.

[0034] Spring steel has good elasticity. When the cable tray comes into contact with the guide plate 5 during the laying process, the guide plate 5 can produce a certain degree of elastic deformation. This elasticity can buffer the cable and prevent the cable from being damaged by rigid collision.

[0035] See Figure 1-3 The support arm body 3 and the support rod 9 are made of stainless steel.

[0036] Stainless steel possesses excellent corrosion resistance. In cable tray support applications, they may be exposed to various harsh environmental conditions, such as damp basements, industrial plants containing corrosive gases (e.g., chemical workshops), or outdoor acid rain environments. The stainless steel support body 3 and support rod 9 can resist the erosion of these environmental factors, effectively preventing rust and corrosion. For example, in buildings near the sea, the air contains a large amount of salt, and ordinary metal supports are easily corroded, while stainless steel can maintain structural integrity and performance for a long time, ensuring the stable operation of the cable tray system.
