Description

Technical Field

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

[0002] Currently, during the installation of branch cable trays for rows of cables at construction sites, the extension direction of the branch cable tray is sometimes obstructed by the adjacent cable tray. It is necessary to bend and raise the branch cable tray, create a tee, and then bend it again to cross the adjacent cable tray to complete the installation. Therefore, the bending components for the branch cable tray need to be cut, fabricated, and then installed on-site by the installation workers.

[0003] Therefore, the current construction methods result in relatively poor component quality and low construction efficiency. Utility Model Content

[0004] In view of this, the present invention provides a cable transfer tray to solve the problems of relatively poor component quality and low construction efficiency in the current construction methods.

[0005] In a first aspect, this utility model provides a cable adapter tray, which includes:

[0006] A branch channel is suitable for installation above the main cable tray; the bottom elevation of the branch channel is higher than the elevation of the adjacent cable tray to be crossed; the branch channel is connected to the corresponding branch cable tray, so that the branch cable tray crosses the adjacent cable tray.

[0007] An adapter hole is provided at the bottom of the branch channel; the adapter hole connects the branch channel to the main cable tray.

[0008] Beneficial Effects: This embodiment, by setting branch channels and transition holes, allows for direct installation of the branch channels on the corresponding main cable trays in practical applications. The branch channels are then connected to the branch trays, enabling cables from the main cable trays to enter the branch trays via the branch channels and transition holes. Therefore, the cable transition tray in this embodiment forms a standardized, integrated module with upper and lower layers, connecting the main cable trays and branch trays. This facilitates the integration and branching of rows of cable trays, solving the problem of obstruction by adjacent cables during branching, while avoiding on-site cutting and processing, thus improving construction efficiency. Furthermore, it enables standardized engineering production, modular installation, and multi-scenario configuration.

[0009] Furthermore, it enables rapid branching and installation of rows of cable trays, avoiding bends in the main cable tray route and ensuring the straightness and aesthetics of the main cable trays. At the same time, it avoids the drawbacks of on-site fabrication and bending, such as material waste, increased labor costs, reduced installation efficiency, poor installation quality, and high safety risks.

[0010] Furthermore, installing cable transfer trays on existing main cable trays allows for minimal modification to the existing cable trays. It eliminates the need to cut, fabricate, bend, install, create tees, and then bend back to the original elevation. The cable transfer trays can be installed directly, improving construction efficiency.

[0011] In one alternative implementation, the branch channel includes:

[0012] A support channel is suitable for installation above the main cable tray; the bottom elevation of the support channel is higher than the elevation of the adjacent cable tray to be crossed; the bottom of the support channel is provided with the transition hole.

[0013] A branch interface is provided along the length of the support channel on at least one side of the support channel; the branch interface is connected to the support channel and is connected to a corresponding branch cable tray.

[0014] In one optional implementation, the branch channel further includes:

[0015] The buffer channel has a flared shape; the larger end of the buffer channel is connected to the support channel, and the smaller end of the buffer channel is connected to the branch interface.

[0016] Beneficial Effects: This embodiment, by setting up a buffer channel, addresses the issue of cable bending when cables from the main cable tray enter the branch cable tray. Excessive bending angles can damage the cable. Therefore, the buffer channel increases the bending radius during the bending process; the larger the larger end of the buffer channel, the greater the bending radius it can accommodate, thus preventing cable damage. This significantly improves cable laying efficiency during subsequent installation, shortens the cable route, reduces the amount of cable laid, and lowers cable procurement costs.

[0017] In one alternative embodiment, in the length direction of the support channel, the larger end of the buffer channel is at least 200 mm longer than the smaller end of the buffer channel.

[0018] In one alternative embodiment, the bottom surface of the buffer channel is inclined, and in the vertical direction, the side of the bottom surface of the buffer channel near the branch interface is higher than the side of the bottom surface of the buffer channel near the support channel.

[0019] In one alternative embodiment, the buffer channel is provided with a closure at one end along its length and / or at the top of the buffer channel.

[0020] Beneficial effects: By setting up a sealing component, the cable tray of the transition section can be shielded to prevent the external environment from causing additional impact on the cables inside the cable tray, thereby providing a certain degree of protection for the cables inside the cable tray.

[0021] In one alternative implementation, the branch channel is detachably connected to the main cable tray and the branch cable tray.

[0022] In one alternative embodiment, the cable tray further includes:

[0023] The main channel has two ends adapted to be connected to the main cable tray; the branch channel is connected to the main channel, and the main channel and the branch channel are connected via the adapter hole.

[0024] In one optional implementation, the main channel and the branch channel are an integral structure.

[0025] In one alternative implementation, the main channel is detachably connected to the main cable tray. Attached Figure Description

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Currently, during the installation of branch cable trays 5 for rows of cables at the construction site, sometimes the extension direction of branch cable tray 5 is obstructed by adjacent cable trays. It is necessary to bend and raise branch cable tray 5, open a tee, and then bend it again to cross the adjacent cable tray to complete the installation of the cable branch cable tray 5. Therefore, the bending components of branch cable tray 5 need to be cut, fabricated, and then installed on-site by installation workers.

[0040] Therefore, the current construction methods result in relatively poor component quality and low construction efficiency.

[0041] In view of this, the present invention provides a cable transfer tray to solve the problems of relatively poor component quality and low construction efficiency in the current construction methods.

[0042] In this embodiment, the cable transfer tray is a standard module that can be mass-produced in the factory. It can reduce safety risks by eliminating cutting and processing operations on the construction site. It can quickly connect with traditional cable trays to create branch cable trays when installing new rows of cable trays. It can quickly add branch cable trays to existing cable trays. It can ensure that the bottom of the cable trays remains at the same elevation when branching from rows of cable trays, improving the overall appearance. It can reduce cable bending during subsequent cable laying, thereby reducing cable usage and improving cable laying efficiency. While saving material and labor costs, it reduces safety risks and improves installation quality, installation efficiency, and appearance.

[0043] The following is combined with Figures 1 to 6 The following describes specific embodiments of this utility model.

[0044] According to an embodiment of the present invention, a cable adapter tray is provided, which includes a branch channel 1 and an adapter hole 2.

[0045] Specifically, in this embodiment, the branch channel 1 is adapted to be installed above the main cable tray 4. That is, the main cable tray 4 can be an existing cable tray, and the branch channel 1 is a branch cable tray added to the existing cable tray. The main cable tray 4 can also be a newly constructed cable tray. After installing the branch channel 1 above the main cable tray 4, the main cable tray 4 is located in the lower area of ​​the cable transfer tray, and the branch channel 1 is located in the upper area of ​​the cable transfer tray. In this way, rapid cable laying can be achieved during transfer.

[0046] Furthermore, in this embodiment, the bottom elevation of the branch channel 1 is higher than the elevation of the adjacent cable tray to be crossed. The branch channel 1 needs to be connected to the corresponding branch cable tray 5 so that the branch cable tray 5 crosses the adjacent cable tray. This ensures that when installing the branch cable tray 5, it will not affect the adjacent cable tray during the process of crossing it.

[0047] Of course, branch channel 1 can be directly led out to a separate branch cable tray 5. In this case, branch channel 1 only has one connection port, which is connected to the branch cable tray 5, such as... Figure 4 As shown. Alternatively, the cables in the main cable tray 4 can be led out to another branch cable tray 5 and merged with the cables in the other branch cable tray 5. In this case, the branch channel 1 can be equipped with two connection ports, one of which connects to the first branch cable tray 5 and the other connects to the second branch cable tray 5, as shown. Figure 3 As shown.

[0048] Furthermore, in this embodiment, the adapter hole 2 is opened at the bottom of the branch channel 1, and the adapter hole 2 connects the branch channel 1 to the main cable tray 4.

[0049] With this configuration, this embodiment, by setting up branch channel 1 and adapter hole 2, allows branch channel 1 to be directly installed on the corresponding main cable tray 4 in practical applications. Then, branch channel 1 is connected to branch cable tray 5, enabling cables in the main cable tray 4 to enter the branch cable tray 5 via branch channel 1 and adapter hole 2. Therefore, the cable adapter cable tray in this embodiment forms a standardized modular structure with upper and lower layers, connecting the main cable trays and branch cable trays 5 to quickly integrate and branch the cable trays, solving the problem of obstruction by adjacent cables when branching cable trays, while avoiding on-site cutting and processing, thus improving construction efficiency. Furthermore, it enables standardized engineering production, modular installation, and multi-scenario configuration.

[0050] Furthermore, it enables rapid branching and installation of rows of cable trays, avoiding bends in the main cable tray route and ensuring the straightness and aesthetics of the main cable trays. At the same time, it avoids the drawbacks of on-site fabrication and bending, such as material waste, increased labor costs, reduced installation efficiency, poor installation quality, and high safety risks.

[0051] Furthermore, installing a cable transfer tray on the existing main cable tray 4 eliminates the need for extensive modifications to the existing cable tray. It avoids the need to cut the existing tray, fabricate and bend it on-site, install it, and then bend it back to its original elevation after creating a tee. The cable transfer tray can be installed directly, improving construction efficiency.

[0052] Furthermore, in an optional embodiment, the branch channel 1 includes a support channel 11 and a branch interface 12.

[0053] Specifically, in this embodiment, the support channel 11 is adapted to be installed above the main cable tray 4, and the bottom elevation of the support channel 11 is higher than the elevation of the adjacent cable tray to be crossed. The bottom of the support channel 11 is provided with the transition hole 2.

[0054] Furthermore, along the length of the support channel 11, a branch interface 12 is provided on at least one side of the support channel 11. The branch interface 12 communicates with the support channel 11 and is connected to a corresponding branch cable tray 5. That is, when the branch interface 12 is only provided on one side of the support channel 11, the branch interface 12 is directly connected to the separately extended branch cable tray 5, such as... Figure 5 As shown. When branch interfaces 12 are located on both sides of the support channel 11, both branch interfaces 12 are connected to branch bridges 5, as shown. Figure 4 As shown.

[0055] Furthermore, in an optional embodiment, the branch channel 1 further includes a buffer channel 13, which has a flared shape. The larger end of the buffer channel 13 is connected to the support channel 11, and the smaller end of the buffer channel 13 is connected to the branch interface 12.

[0056] With this configuration, in this embodiment, a buffer channel 13 is provided. When the cable from the main cable tray 4 enters the branch cable tray 5, the cable needs to be bent. If the bending angle is too large, it will damage the cable. Therefore, the buffer channel 13 increases the radius of the cable during the bending process. The larger the larger end of the buffer channel 13, the larger the bending radius it can accommodate, thus avoiding cable damage. In subsequent cable laying, this greatly improves cable laying efficiency, shortens the cable laying route, reduces the amount of cable laid, and lowers cable procurement costs.

[0057] Furthermore, in an optional embodiment, in the length direction of the support channel 11, the larger end of the buffer channel 13 is at least 200mm longer than the smaller end of the buffer channel 13. That is, the two edges of the flared structure in the length direction of the support channel 11 are 100mm larger than the width of the branch cable tray 5 on each side, and the height of the flared structure is the sum of the heights of the upper and lower layers. This ensures that the bending radius during cable laying meets national standards and facilitates subsequent cable laying.

[0058] Furthermore, in an optional embodiment, the bottom surface of the buffer channel 13 is inclined, and in the vertical direction, the side of the bottom surface of the buffer channel 13 near the branch interface 12 is higher than the side of the bottom surface of the buffer channel 13 near the support channel 11. That is, the bottom of the buffer channel 13 is provided with a slope, which allows the cable to be well supported during the transition, even if there is a height difference, preventing the cable from being suspended and damaged.

[0059] Furthermore, in an optional embodiment, the buffer channel 13 is provided with a closure 14 at both its ends along the length direction and at its top. Of course, the closure 14 may only be provided at the ends or the top. This embodiment is merely an example and is not intended to limit the scope. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect is achieved.

[0060] With this configuration, the cable tray of the transition section can be shielded by the enclosure 14 in this embodiment, preventing the external environment from causing additional impact on the cables inside the cable tray, thereby providing a certain degree of protection for the cables inside the cable tray.

[0061] Furthermore, in an optional embodiment, the branch channel 1 is detachably connected to the main cable tray 4 and the branch cable tray 5. For disassembly and assembly, a dedicated cable tray connecting piece and fixing bolts can be used for connection. Of course, this embodiment is merely illustrative and is not intended to limit the scope; those skilled in the art can modify it according to actual circumstances to achieve the same technical effect.

[0062] Furthermore, in an optional embodiment, the cable transfer tray further includes a main channel 3, both ends of which are adapted to be connected to the main cable tray 4. The branch channel 1 is connected to the main channel 3, and the main channel 3 and the branch channel 1 are connected via the transfer hole 2.

[0063] In other words, the main cable tray 4 is a newly constructed cable tray. The two ends of the active channel are connected to two main cable trays 4 respectively. The branch channel 1 is located above the main cable tray 4; that is, the main cable tray 4 is located in the lower area of ​​the cable transfer tray, and the branch channel 1 is located in the upper area of ​​the cable transfer tray. Figure 1 and Figure 2 As shown.

[0064] Furthermore, in an optional implementation, the main channel 3 and the branch channel 1 are an integral structure.

[0065] Furthermore, in an optional embodiment, the main channel 3 is detachably connected to the main cable tray 4. For the disassembly and assembly method, it can be connected using dedicated cable tray connecting pieces and fixing bolts. Of course, this embodiment is merely illustrative and is not intended to limit the scope; those skilled in the art can modify it according to actual circumstances to achieve the same technical effect.

[0066] Bolt holes can be pre-drilled on the main cable tray 4 and branch cable tray 5, and then the cable transfer cable tray can be quickly spliced ​​and installed with the cable tray using special connecting pieces and fixing bolts.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
