Description

Technical Field

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

[0002] Cable trays are important devices for laying cables, especially suitable for overhead laying of all-plastic cables, and play a basic supporting role in power transmission systems.

[0003] With the continuous increase in electricity demand in the construction sector, the use of multi-layer stacked cable trays that can make efficient use of space is increasing. However, the existing structure has obvious defects. The operating space for cables located on the lower layer is limited during maintenance, which brings great inconvenience to inspection, maintenance and fault handling.

[0004] To address the aforementioned issues, this application proposes a multi-layer stacked cable tray. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a multi-layer stacked cable tray.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-layer superimposed cable tray includes a single-layer cable tray, an operation port is provided on the single-layer cable tray, a support rod is installed on the single-layer cable tray through the operation port, a movable plate is rotatably connected to the support rod, a connecting plate is installed on the movable plate, a screw is movably inserted into the connecting plate, and the screw is threadedly connected to the single-layer cable tray.

[0007] The single-layer cable tray is equipped with a blocking component.

[0008] The movable plate has a through-hole for mounting, and the movable plate is movably fitted onto the support rod through the mounting hole; the movable plate is provided with a lubrication component, and the mounting hole facilitates the fitting of the movable plate onto the support rod.

[0009] The lubrication assembly includes a manifold formed on the movable plate, the output end of which is connected to the mounting hole. By setting the lubrication assembly, lubricating oil can easily enter the mounting hole through the manifold to lubricate the movable plate and the support rod.

[0010] The movable plate has a filter screen installed inside the input end of the manifold, which is used to intercept dust.

[0011] The blocking component includes a storage slot on a single-layer cable tray. A threaded rod is rotatably connected to the single-layer cable tray through the storage slot. A blocking block is slidably connected to the single-layer cable tray through the storage slot. A threaded groove is provided at the bottom of the blocking block. The threaded rod is threadedly connected to the blocking block through the threaded groove. The blocking component is used to block the open movable plate.

[0012] The single-layer cable tray is equipped with bearings through a storage slot. The outer bottom end of the threaded rod is connected to the inner ring of the bearing. By setting the bearing, the threaded rod is supported and its rotation is assisted.

[0013] A rotating block is installed on the threaded rod, which facilitates the rotation of the threaded rod.

[0014] A rubber pad is installed on one side of the abutment block to minimize wear between the abutment block and the movable plate.

[0015] The beneficial effects of this utility model are:

[0016] By unscrewing the screws and then rotating the movable plate, the operating port is exposed, making it easier to inspect and maintain the cables laid in the lower single-layer cable tray. This improves the operating space for the lower cables during maintenance and facilitates inspection, maintenance, and troubleshooting.

[0017] By setting up a lubrication assembly and using a filter screen to intercept dust, the dust intercepted by the filter screen is cleaned when using the manifold. Then, lubricating oil is injected into the manifold, and the lubricating oil is delivered to the support rod and the movable plate for lubrication through the manifold. This helps to avoid the movable plate from getting stuck due to aging of the movable plate and its related parts, and achieves the goal of ensuring the smooth rotation of the movable plate as much as possible.

[0018] By setting up a stop component and rotating the rotating block, the stop block is moved upward. At this time, the rubber pad presses one side of the movable plate, thereby limiting the position of the movable plate when it is opened, and minimizing the impact of the movable plate on the operator's maintenance work.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0035] Reference Figure 1-6 A multi-layer stacked cable tray includes a single-layer cable tray 1 with an operating port 2. A support rod 3 is installed on the single-layer cable tray 1 through the operating port 2. A movable plate 4 is rotatably connected to the support rod 3. A connecting plate 402 is installed on the movable plate 4. A screw 403 is movably inserted into the connecting plate 402 and threadedly connected to the single-layer cable tray 1. Specifically, by unscrewing the screw 403 and then rotating the movable plate 4, the operating port 2 is exposed. At this time, the cables laid in the lower single-layer cable tray 1 can be inspected through the operating port 2, thereby improving the operating space for the lower cables during inspection and facilitating inspection, maintenance, and fault handling.

[0036] When connecting multiple single-layer cable trays 1, bolts and nuts are used for fixing via the assembly holes between the single-layer cable trays 1. Figure 1 It can be seen that the bolts and nuts are used for the connection positions between multiple single-layer cable trays 1, and the assembly holes have storage openings to ensure that the bolts and nuts do not protrude, effectively preventing the bolts and nuts from obstructing the normal rotation of the movable plate 4.

[0037] Reference Figure 3 and Figure 4 The movable plate 4 has a through hole 401. The movable plate 4 is movably fitted onto the support rod 3 through the mounting hole 401. The mounting hole 401 is designed to fit the movable plate 4 onto the support rod 3, ensuring that the movable plate 4 rotates along the specified motion trajectory.

[0038] Reference Figure 2-5 The movable plate 4 is equipped with a lubrication component 5, which includes a manifold 501 formed on the movable plate 4. The output end of the manifold 501 is connected to the mounting hole 401. A filter screen 502 is installed inside the input end of the movable plate 4 through the manifold 501. Specifically, according to the above technical solution, the filter screen 502 intercepts dust, minimizing the possibility of dust entering the manifold 501 and clogging it. When using the manifold 501, a sharp object, such as tweezers, is used to clean the dust intercepted by the filter screen 502. Then, lubricating oil is injected into the manifold 501, and the lubricating oil is delivered between the support rod 3 and the movable plate 4 through the manifold 501 for lubrication. This helps to prevent the movable plate 4 from getting stuck due to aging of the movable plate 4 and its related parts, thus achieving the goal of ensuring the smooth rotation of the movable plate 4 as much as possible.

[0039] Reference Figure 2 , Figure 4 and Figure 6A blocking component 6 is provided on the single-layer cable tray 1. The blocking component 6 includes a storage groove 601 opened on the single-layer cable tray 1. A threaded rod 603 is rotatably connected to the single-layer cable tray 1 through the storage groove 601. A stop block 604 is slidably connected to the single-layer cable tray 1 through the storage groove 601. A threaded groove 605 is opened at the bottom of the stop block 604. The threaded rod 603 is threadedly connected to the stop block 604 through the threaded groove 605. A rotating block 606 is installed on the threaded rod 603. A rubber pad 607 is installed on one side of the stop block 604. According to the above technical solution, specifically, by rotating the rotating block 606, it drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 drives the stop block 604 to move upward. At this time, the rubber pad 607 presses one side of the movable plate 4, thereby achieving the effect of limiting the position of the movable plate 4 when it is opened, and minimizing the impact of the movable plate 4 on the operator's maintenance work.

[0040] Reference Figure 6 The single-layer cable tray 1 is equipped with a bearing 602 through the storage slot 601. The outer side of the bottom end of the threaded rod 603 is connected to the inner ring of the bearing 602. The bearing 602 is used to support the threaded rod 603 and assist the rotation of the threaded rod 603.

[0041] Working principle:

[0042] This multi-layered cable tray uses a filter screen 502 to intercept dust, minimizing the risk of dust entering and clogging the manifold 501. When using the manifold 501, a sharp object is used to clean the dust intercepted by the filter screen 502. Subsequently, lubricating oil is injected into the manifold 501, which then delivers the lubricating oil between the support rod 3 and the movable plate 4 for lubrication. This helps prevent the movable plate 4 from jamming due to aging or other reasons, thus ensuring smooth rotation of the movable plate 4 as much as possible.

[0043] This multi-layered cable tray allows for the removal of screws 403 and the subsequent rotation of the movable plate 4, exposing the operating port 2. This allows for the inspection and maintenance of the cables laid in the lower single-layer cable tray 1 through the operating port 2, thereby increasing the operating space for the lower layer cables during maintenance and facilitating inspection, maintenance, and troubleshooting.

[0044] This multi-layered cable tray, by rotating the rotating block 606, causes the threaded rod 603 to rotate. The rotation of the threaded rod 603 causes the abutment block 604 to move upward. At this time, the rubber pad 607 presses one side of the movable plate 4, thereby achieving the effect of limiting the position of the movable plate 4 when it is opened, so as to minimize the impact of the movable plate 4 on the operator's maintenance work.

[0045] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
