Description

Technical Field

[0001] This application relates to the technical field of pedestrian cable trays, and particularly to a movable cable tray. Background Art

[0002] A cable tray is a structure used to support, protect, and install cables, wires, etc. They are usually used inside or outside buildings to organize and support power, communication, and control cables, as well as other pipeline systems. The cable tray includes a bottom channel and a cover plate that closes the bottom channel from above. In order to facilitate the maintenance and replacement of internal cables and equipment, as well as the cleaning of the cable tray and the cover plate itself, the cover plate and the bottom channel are designed to be detachably connected, usually fixed by bolts or detachable clamps, etc.

[0003] Among cable trays, there is a type of pedestrian cable tray, which is specially designed for outdoor environments, provides a passage between equipment, and uses a cover plate to provide a safe walkway for personnel to pass through. This passage can serve as a path connecting different equipment, enabling personnel to easily access the equipment for operation, maintenance, or data collection, which is crucial for maintaining the normal operation of the equipment and extending its lifespan.

[0004] Pedestrian cable trays are usually exposed to outdoor environments and are affected by weather, pollution, and other environmental factors. The cover plate is prone to wear, corrosion, or other damages. Moreover, pedestrian cable trays are often in areas with intensive human activities, that is, compared with conventional cable trays, they are used and stepped on by personnel more frequently. Therefore, internal inspections and maintenance need to be carried out more frequently to ensure passage safety and the normal operation of the equipment.

[0005] However, in existing cable trays, the cover plate is usually fixed after being inserted into the bottom channel. When disassembling, maintenance personnel need to first stand in the operation empty area beside the cable tray, and then remove the cover plate as a whole and place it aside. During frequent inspections and repairs, the probability of damage to the cover plate increases, which not only affects the safety of personnel passage but also affects the degree of protection for cables. Therefore, there is still room for improvement. Utility Model Content

[0006] In order to reduce the probability of damage to the cover plate when inspecting and repairing the cable tray, and at the same time improve the convenience of inspection and repair, this application provides a movable cable tray.

[0007] The movable cable tray provided by this application adopts the following technical solutions:

[0008] A movable cable tray includes a bottom channel and a cover plate that closes the bottom channel from top to bottom. An accommodating cavity for placing cables is formed inside the bottom channel. A hinge is connected between one side of the bottom channel and one side of the cover plate, and the other side of the bottom channel and the other side of the cover plate are detachably connected through a separable component.

[0009] By adopting the above technical solution, the conventional cover plate and bottom groove need to be completely disassembled for maintenance. In view of the frequent maintenance requirements of the special cable bridge for pedestrians, in this application, one side of the cover plate is rotatably connected to the bottom groove, and the other side of the cover plate is reliably connected to the bottom groove through a separable component, so as to realize the movable connection between the cover plate and the bottom groove as a whole; only by separating the separable component and then turning up the cover plate can maintenance be carried out. On the one hand, the convenience of maintenance is improved, and on the other hand, the probability of accidental collision and damage of the cover plate due to placement is reduced, ensuring the safety of the staff walking.

[0010] Optionally, anti-slip protrusions are provided at the upper end of the cover plate.

[0011] By adopting the above technical solution, since the staff will walk on the cable bridge, anti-slip protrusions are added to strengthen the friction, reduce the probability of the staff slipping and falling, and improve the safety.

[0012] Optionally, the separable component is arranged on the side of the bottom groove close to the operation free area.

[0013] By adopting the above technical solution, the installation position of the separable component is defined, further improving the convenience of maintenance.

[0014] Optionally, a plurality of the separable components are arranged at intervals along the length direction of the cover plate.

[0015] By adopting the above technical solution, a plurality of separable components are used to replace the conventional bolts to ensure the tightness of the cover of the cover plate and the bottom groove and the stability of the installation of the cover plate, avoiding potential safety risks caused by partial warping of the cover plate.

[0016] Optionally, the separable component includes a buckle body connected with a hook ring and a hook piece fixedly hooked with the hook ring.

[0017] By adopting the above technical solution, the separation is realized by the cooperation of the hook ring and the hook piece. The parts can be directly purchased, which is safe and reliable while controlling the overall production cost of the cable bridge.

[0018] Optionally, the hook piece is connected to the upper side of the cover plate, and the buckle body is connected to one side of the bottom groove.

[0019] By adopting the above technical solution, the hook ring is connected to the buckle body. Compared with installing the buckle body on the cover plate, the installation position set in this application makes the hook ring not drive the cover plate to press down together when hooking, avoiding the deformation that the cover plate may cause due to frequent collision with the bottom groove, thus ensuring the safety of walking.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. In view of the frequent maintenance requirements for this special cable tray for pedestrians, in this application, one side of the cover plate is rotatably connected to the bottom groove, and the other side of the cover plate is reliably connected to the bottom groove through a separable component, thus realizing the movable connection between the cover plate and the bottom groove as a whole; only by separating the separable component and then flipping up the cover plate can maintenance be carried out. On the one hand, the convenience of maintenance is improved, and on the other hand, the probability of accidental collision and damage of the cover plate due to placement is reduced, ensuring the safety of the staff walking.

[0022] 2. This application strengthens friction by adding anti-slip protrusions, reducing the probability of staff slipping and falling, and improving safety.

[0023] 3. This application uses multiple separable components to replace conventional bolts, ensuring the tightness of the cover plate and the bottom groove and the stability of the cover plate installation, and avoiding potential safety risks caused by partial warping of the cover plate. Description of the Drawings

[0025] Figure 2 is Figure 1 a partial enlarged view of part A in

[0026] Description of the Reference Numerals: 1, bottom groove; 11, accommodation cavity; 2, cover plate; 21, anti-slip protrusion; 3, hinge; 4, separable component; 41, buckle body; 411, hook ring; 42, hook piece. Detailed Embodiment

[0027] The following further describes this application in detail with reference to the attached Figure 1-2 drawings.

[0028] A coordinate system XYZ is set in this article, where the positive direction of the Z-axis represents the upper side, the negative direction of the Z-axis represents the lower side, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the rear, the positive direction of the X-axis represents the right side, and the negative direction of the X-axis represents the left side.

[0029] The embodiment of this application discloses a movable cable tray. Referring to Figure 1 and Figure 2 , the movable cable tray includes a bottom groove 1 and a cover plate 2 that covers the bottom groove 1 from top to bottom. An accommodation cavity 11 for placing cables is formed inside the bottom groove 1. An anti-slip protrusion 21 is integrally formed at the upper end of the cover plate 2. The anti-slip protrusion 21 has the effect of enhancing friction, reducing the probability of staff slipping and falling, and improving the passing safety.

[0030] During maintenance, the maintenance personnel stand at the operation empty area on the right side of the movable bridge. A hinge 3 is installed between the left side of the bottom groove 1 and the left side of the cover plate 2 by bolts, and the bottom groove 1 and the cover plate 2 are rotationally connected through the hinge 3. In this application, an example is shown where a hinge 3 is installed at both the front and rear ends on the left side of the cover plate 2; a separable component 4 is fixed between the right side of the bottom groove 1 and the right side of the cover plate 2 by bolts. When the cover plate 2 is a regular cuboid, multiple separable components 4 are arranged at intervals along the length direction of the cover plate 2. When the cover plate 2 is irregular, at least one separable component 4 is connected to each side of the cover plate 2.

[0031] The separable component 4 can be any existing component that can keep the lower end surface of the bottom cover closely attached to the upper end surface of the bottom groove 1. In this application, a buckle is taken as an example. The buckle can be directly purchased, which is safe and reliable while controlling the overall production cost of the bridge. The separable component 4 includes a buckle body 41 connected with a hook ring 411 and a hook piece 42 hooked and fixed to the hook ring 411. The buckle body 41 is fixed to the right side of the bottom groove 1 by bolts, and the hook piece 42 is bolted to the right side of the cover plate 2, thereby realizing the detachable connection between the right side of the cover plate 2 and the right side of the bottom groove 1.

[0032] The implementation principle of a movable bridge in an embodiment of this application is as follows: The right side of the bridge is a conventional operation empty area. In this application, the left side of the cover plate 2 is rotationally connected to the bottom groove 1, and the right side of the cover plate 2 is reliably connected to the bottom groove 1 through the separable component 4.

[0033] When maintenance is not required, the separable component 4 is used to fix the cover plate 2 and the bottom groove 1, ensuring the tightness of the cover between the cover plate 2 and the bottom groove 1 and the stability of the installation of the cover plate 2, avoiding potential safety risks caused by partial warping of the cover plate 2. At the same time, anti-slip protrusions 21 are used to enhance the safety of walking, and the staff can walk freely on the cover plate 2.

[0034] When maintenance is required, the staff stands on the right side of the bridge and pulls the hook ring 411 until the hook ring 411 disengages from the hook piece 42 from top to bottom. Before the hook ring 411 disengages from the hook piece 42, the cover plate 2 still remains in contact with the bottom groove 1; when the hook ring 411 disengages from the hook piece 42, the right side of the cover plate 2 is released, but it is not easy to bump against the bottom groove 1, thereby reducing the possibility of deformation of the cover plate 2 caused by accidental bumping. Subsequently, the cover plate 2 is turned up for maintenance. After the maintenance is completed, the cover plate 2 is turned down and fixed, and the bridge can be used for the staff to walk again.

[0035] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
