Description

Technical Field

[0001] This utility model relates to the field of cable laying, specifically a cable tray mechanism within a facility. Background Technology

[0002] In building electrical engineering, the laying of cables and wires usually requires appropriate protective cable trays. Common cable trays can be enclosed or open, and are mainly used for the protection of wiring.

[0003] In many situations, cabling within a facility needs to be laid both vertically and horizontally, resulting in vertical bends. Examples include cable shafts, factory workshops, and dedicated passageways. These bends are not planar bends but rather changes in orientation from vertical to horizontal, making them prone to deformation due to gravity. Especially in right-angle or T-junction cable trays, deformed, drooping cables may repeatedly contact and rub against the tray walls, causing wear at the cable's base and leading to wiring problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray mechanism in a facility that provides curved support for cables at bends and can isolate the cables, thereby improving cable protection.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A cable tray mechanism for a facility includes an upright channel with multiple channel openings on one side. A corresponding and fixed horizontal channel is connected to each channel opening. The horizontal channel extends horizontally and has a transverse shaft inside one end near the upright channel. Strip-shaped holes are provided on both sides of the horizontal channel for the transverse shaft to pass through. The transverse shaft has external threads on its surface and fastening nuts at both ends. The transverse shaft has detachable isolation plates, with at least two isolation plates and several sleeves between adjacent isolation plates. The sleeves are coaxially connected to the transverse shaft.

[0007] The sleeve is a circular straight cylinder structure, and a transverse hole is coaxially centered inside the sleeve. The diameter of the transverse hole is larger than the transverse axis.

[0008] The isolation plate is a circular thin sheet, and a spiral tube coaxial with it is fixed through the center of the isolation plate. The spiral tube is threadedly connected to the horizontal axis. One end of the horizontal hole is provided with a slot coaxial with it. The spiral tube and the slot are movably inserted into each other. The depth of the slot is longer than that of the spiral tube.

[0009] The strip-shaped hole extends vertically, and the width of the strip-shaped hole is greater than the diameter of the horizontal axis.

[0010] It also includes an annular gasket that is movably fitted with the horizontal axis, wherein the inner circle of the annular gasket is larger than the horizontal axis, and the annular gasket is disposed in the gap between the outermost isolation piece and the inner wall of the horizontal channel.

[0011] A fixing frame is provided below the horizontal channel. The fixing frame includes a front plate located below the horizontal channel. Side plates are vertically fixed on both sides of the front plate. The front plate and side plates form a U-shaped structure surrounding the vertical channel. A mounting plate extending horizontally outward is provided at the end of the side plate away from the front plate. A support plate is provided on the top side of the front plate. The side of the support plate near the vertical channel is vertically fixed to the top side of the front plate. The top side of the support plate is in contact with the bottom surface of the horizontal channel.

[0012] The bottom side of the tray and the horizontal channel has corresponding mounting holes, and mounting bolts pass through the mounting holes. A triangular reinforcing rib is provided between the tray and the front plate.

[0013] The support plate is symmetrically welded and fixed with lifting nuts on both sides. The outer side of the strip hole is provided with mounting parts for supporting and fixing the two ends of the horizontal shaft. The mounting parts include a screw rod that passes through the lifting nut and is threaded to it. The top of the screw rod is provided with a rotating cap that is rotatably connected to it.

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] In building electrical engineering, the laying of cables and wires usually requires appropriate protective cable trays. Common cable trays can be enclosed or open, and are mainly used for the protection of wiring.

[0026] In many situations, cabling within a facility needs to be laid both vertically and horizontally, resulting in vertical bends. Examples include cable shafts, factory workshops, and dedicated passageways. These bends are not planar bends but rather changes in orientation from vertical to horizontal, making them prone to deformation due to gravity. Especially in right-angle or T-junction cable trays, deformed, drooping cables may repeatedly contact and rub against the tray walls, causing wear at the cable's base and leading to wiring problems.

[0027] In situations such as shafts and high-rise buildings, a large number of vertical cables are laid. After the cables are vertically fixed and laid, they need to be bent horizontally at the corresponding floors or heights as needed to enter the distribution cabinet or horizontal cable tray / trough. When there are many cables, due to gravity, the cables can maintain a good arch at the bends during the initial installation. However, as they are used, they gradually deform, and the bottom of the cable will gradually sag against the trough wall at the bend. Under the pull of gravity, they repeatedly rub against the right-angle bend of the trough wall, which can easily cause damage. At the same time, because the bends are designed to maintain the curvature, the cables at the bends are usually not tightly compressed and fixed, so they tend to become loose and messy during use, making it difficult to maintain a neat layout. Therefore, the maintenance frequency at the bends is high, often causing maintenance problems for the system transmission.

[0028] This cable tray mechanism primarily achieves secure support and organization of cables by adding improved components at bending points, thereby extending cable lifespan and improving electrical safety. Its main structure employs detachable and flexibly assembled modular components, including:

[0029] A vertically extending, fixed passageway 1 is provided within the facility. Multiple passageway openings are provided on one side of the vertical passageway 1, and corresponding and fixed horizontal passageways 2 are connected to each of these openings. The horizontal passageways 2 and the passageway openings can be fixed during construction using bolts, or they can be prefabricated in the factory by welding.

[0030] At one end of the horizontal channel 2 near the vertical channel is a connection port, which facilitates cable splitting and turning. Near the connection port is a horizontal shaft 3, which extends horizontally in the length direction and is consistent with the width direction of the horizontal channel 2. The horizontal shaft 3 is a helical shaft with external threads on its outer surface. The horizontal shaft 3 is detachably and freely combinable equipped with an isolation plate 4 and a sleeve 5. The sleeve 5 is a circular straight cylinder structure that can provide curved support for turning cables. A horizontal hole 8 is coaxially centered inside the sleeve 5. The diameter of the horizontal hole 8 is larger than that of the horizontal shaft 3, which can be easily fitted over the horizontal shaft 3 and its position can be freely adjusted relative to the horizontal shaft 3. One end of the transverse hole 8 is provided with a slot 7 coaxial with it. The isolation plate 4 is a circular thin plate. A screw tube 6 coaxial with it is fixed through the center of the isolation plate 4. The screw tube 6 is threadedly connected to the transverse shaft 3, so that the position of the isolation plate 4 can be adjusted and fixed arbitrarily. The screw tube 6 and the slot 7 are movably inserted. The slot 7 can easily accommodate the screw tube 6, so that the two sides of the isolation plate 4 are close to the sleeve 5 respectively, forming an annular isolation space.

[0031] A flat groove 19 is provided on the side wall of the solenoid 6 to facilitate its rotation using tools.

[0032] During installation, all isolation plates 4 and sleeves 5 are set in the horizontal channel 2, with the isolation plates 4 located at both ends of the horizontal axis 3. One or two sleeves 5 are set between adjacent isolation plates 4. The number of sleeves 5 can be used to obtain partition spaces of different widths. In this way, while guiding, bending and supporting the cables, different cables can also be isolated and organized, which is conducive to maintaining the neat arrangement of cables for a long time.

[0033] Symmetrically arranged vertically extending strip-shaped holes 9 are provided on both sides of the horizontal channel 2. The width of the strip-shaped holes 9 is greater than the diameter of the horizontal axis 3, and both ends of the horizontal axis 3 pass through the strip-shaped holes 9. Fastening nuts 10 can be fitted at both ends of the horizontal axis 3. The fastening nuts 10 are located outside the strip-shaped holes 9 and are used to fix the horizontal axis 3. This fixing method allows for flexible adjustment of the height of the horizontal axis 3, thus accommodating both bottom-up and top-down cable bends, and adapting to the height requirements of cables of different strengths. This achieves the best support position and effect, ensuring that the cable is supported and guided by the curved surface on the circumference of the sleeve 5, preventing direct contact with the right-angle connection point of the channel and avoiding friction and damage.

[0034] To accommodate different combinations of horizontal channels 2, sleeves 5, and isolation plates 4 with varying widths, for example:

[0035] Two or three sleeves 5 are installed between the isolation plates 4, such as Figure 1 As shown. It can accommodate and organize cables in different groups.

[0036] A sleeve 5 is installed between the isolation plates 4, such as... Figure 3 Figure 4 As shown, this allows for the creation of small, evenly spaced partitions.

[0037] It also includes an annular gasket, the inner circle of which is larger than the horizontal axis 3 and can be fitted onto the horizontal axis 3. The annular gasket is set outside the outermost isolation piece 4 and fills the gap between the outermost isolation piece 4 and the inner wall of the horizontal channel 2.

[0038] Sleeve 5, isolation plate 4, and annular gasket are all independently designed components, which can be used flexibly according to the cable conditions during assembly, making them very convenient and highly applicable.

[0039] Based on the above structure, since the horizontal axis 3 may affect the reliability of the cable fixation during long-term support, in order to improve the support strength and facilitate the adjustment of the support height, auxiliary support components can be added.

[0040] It can also be equipped with mounting brackets and installation parts.

[0041] A fixing frame is provided below the horizontal channel 2. The fixing frame is a U-shaped structure adapted to the shape of the vertical channel. For ease of description, the fixing frame is defined as including a front plate 11 and a side plate 12 with an integral structure. The side plate 12 consists of two pieces, and one end of the side plate 12 is fixedly connected to both ends of the front plate 11. The side plate 12 and the front plate 11 form a U-shaped structure. The side plate 12 is provided with an outwardly horizontally extending mounting plate 13 at the end away from the front plate 11. The mounting plate 13 is located away from the horizontal channel 2. The vertical channel is fixed in the facility by the mounting plate 13 and bolts, which enhances the fixing effect and increases the support strength of the vertical channel at the bend, avoiding deformation caused by excessive local stress.

[0042] The top side of the front plate 11 is provided with a support plate 14. The side of the support plate 14 near the vertical channel 1 is vertically fixed to the top side of the front plate 11. The top side of the support plate 14 is in contact with the bottom surface of the horizontal channel 2. The support plate 14 and the bottom side of the horizontal channel 2 are provided with corresponding mounting holes 15. Mounting bolts are inserted into the mounting holes 15 to reinforce the support plate 14 and the horizontal channel 2.

[0043] Based on the support plate 14 and the fixing frame, the connection between the horizontal channel 2 and the vertical channel 1, that is, the bending position, is reinforced to improve the support strength of the weak position.

[0044] The support plate 14 is symmetrically welded and fixed with lifting nuts 16 on both sides. There are two mounting components, which are symmetrically arranged relative to the horizontal channel 2. The mounting components are used to support and install the two ends of the horizontal shaft 3. The mounting components include a screw 17 that passes through the lifting nut 16 and is threaded to it. The top end of the screw 17 is provided with a rotating cap 18 that is rotatably connected to it. A vertical plate 20 is fixedly welded to one side of the rotating cap 18. The vertical plate 20 is located outside the strip hole 9. The vertical plate 20 has through holes. The two ends of the horizontal shaft 3 pass through the through holes and are fixed to the side plate 12 by fastening nuts 10. After fixing, the height adjustment no longer depends on the fastening nuts 10, but on the cooperation of the screw 17 and the lifting nuts 16. The bottom end of the screw 17 is also provided with a flat groove 19, which is convenient to rotate with tools to adjust the height of the mounting components, thereby achieving the adjustment of the height of the horizontal shaft 3.

[0045] During use, the cable runs from bottom to top and bends horizontally through the support of the horizontal axis 3 into the horizontal channel 2. The support of the cable by the horizontal axis 3 rests on the mounting piece, which provides durable and reliable support, maintaining its position for a long time without loosening. Furthermore, if the cable deforms or sags during use, the height of the support piece can be adjusted to accommodate the cable.
