Description

Technical Field

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

[0002] A common practice during cable tray installation is to suspend them from the ceiling or wall of a building. This method requires specialized suspension brackets to secure the cable trays and ensure their stability and safety. However, traditional suspension brackets are typically installed directly onto the ceiling or wall using bolts or other fasteners. This method makes it difficult to rotate or adjust the suspension brackets once they are installed.

[0003] Chinese patent CN210577614U discloses a suspension bracket design that incorporates components such as a fixed ring and a floating ring, which together form a mechanism to restrict the bracket's rotation. When the cable tray's orientation needs adjustment, a specific operation can be performed to move the floating ring relative to the fixed ring, thereby releasing the restriction on the bracket's rotation. Once the adjustment is complete, the floating ring will re-engage in the corresponding position of the fixed ring, ensuring the stability of the bracket and cable tray. In certain extreme situations (such as strong earthquakes, extreme winds, and other natural disasters), the fixing components or connectors of the suspension bracket may still loosen or fail, potentially causing the cable tray to detach or tilt, thus posing a serious threat to the safety of surrounding personnel and property. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a suspended cable tray.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A suspended cable tray includes a support plate with multiple hangers on the support plate. The top of each hanger is connected to a support bracket. A rotating member is provided at the bottom of the support plate. The cable tray is placed behind the rotating member after passing through the support plate. An upper pressure plate is slidably engaged on the multiple hangers. An extrusion member is provided on the hangers, which can drive the upper pressure plate to abut against the top of the cable tray.

[0007] Furthermore, the support plate is provided with a lower rubber pad layer.

[0008] Furthermore, the extrusion member is a nut, the upper end of the rod has an external thread, the nut is threaded onto the rod, and the nut is located above the upper pressure plate.

[0009] Furthermore, the nut can be moved vertically downward along the boom to press the upper pressure plate against the cable tray.

[0010] Furthermore, the bottom of the upper pressure plate is provided with an upper rubber pad layer.

[0011] Furthermore, the extrusion member is a spring, which is sleeved on the hanger and positioned between the support and the upper pressure plate.

[0012] Furthermore, the spring drives the upper pressure plate to move toward the support plate.

[0013] Furthermore, the rotating component includes a lower mounting plate, a rotating disk is rotatably connected to the middle of the lower mounting plate, the lower mounting plate is fixedly connected to the bottom of the support plate by bolts, and a cable tray is placed on the rotating disk after passing through the support plate and the lower rubber pad layer.

[0014] Furthermore, the bottom of the support plate is provided with threaded holes that mate with the bolts.

[0015] Furthermore, the support plate and the lower rubber pad layer are provided with through holes to accommodate the rotating disk.

[0016] Compared with existing technologies, the advantages of this invention are: it enables stable suspension and flexible adjustment of cable trays. The combination of the support plate, hangers, and supports provides solid support, while the addition of rotating components allows for more flexible and varied installation angles and directions of the cable trays. The cooperation between the compression components and the upper pressure plate ensures that the cable trays are firmly fixed, effectively preventing shaking and detachment. Simultaneously, the lower and upper rubber pads not only increase friction but also provide shock absorption and cushioning, protecting the cable trays from damage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 3 As shown, a suspended cable tray includes a support plate 1 with multiple hangers 2 on the support plate. Each hanger is connected to a support bracket 3 at its top. The support bracket is existing technology; for example, an anti-seismic support bracket manufactured by Zhuhai Guangle Power Busbar Co., Ltd. can be used. A rotating member 4 is located at the bottom of the support plate. The cable tray 100 is placed on the rotating member after it passes through the support plate. An upper pressure plate 21 is slidably fitted on each of the multiple hangers. A pressing member 22 is provided on each hanger, which drives the upper pressure plate to abut against the top of the cable tray. A gap is left between the cable tray and the hangers, allowing the cable tray to rotate using the rotating member without interfering with the hangers.

[0024] Furthermore, the support plate is provided with a lower rubber pad layer 11, which increases the friction between the cable tray and the support plate, and at the same time plays a role in shock absorption and buffering, protecting the cable tray from damage.

[0025] In at least one embodiment, the pressing member is a nut, and correspondingly, the upper end of the lifting rod has an external thread, with the nut threaded onto the lifting rod and positioned above the upper pressure plate. This structure is simple and easy to implement; the upper pressure plate can be raised or lowered simply by rotating the nut, making operation convenient and the fixing effect reliable.

[0026] In a more detailed design, the nut can be moved vertically downwards along the boom to press the upper pressure plate against the cable tray.

[0027] Furthermore, the upper pressure plate is provided with an upper rubber pad 211 at the bottom, which increases the contact area and friction between the upper pressure plate and the cable tray, while avoiding direct pressure from the upper pressure plate on the cable tray and protecting the surface of the cable tray from damage.

[0028] In some embodiments, such as Figure 4 As shown, the pressing component is a spring 23, which is sleeved on the hanger and positioned between the support and the upper pressure plate. This structure utilizes the spring force to automatically press down the upper pressure plate without manual adjustment.

[0029] In a more detailed design, the spring drives the upper pressure plate to move toward the support plate.

[0030] In at least one embodiment, the rotating component includes a lower mounting plate 41, with a rotating disk 42 rotatably connected to the center of the lower mounting plate. The lower mounting plate is fixedly connected to the bottom of the support plate by bolts 43. The rotating disk passes through the support plate and the lower rubber pad layer, and a cable tray is placed thereon. This structure allows the cable tray to easily rotate around the rotating disk, meeting the installation requirements of different angles and directions, and improving the flexibility and adaptability of installation.

[0031] Furthermore, the bottom of the support plate is provided with threaded holes that mate with the bolts.

[0032] Furthermore, the support plate and the lower rubber pad layer are provided with through holes to accommodate the rotating disk.

[0033] To determine the working procedure, confirm that all necessary components are present, including support plate 1, hanger rod 2, support bracket 3, rotating component 4, upper pressure plate 21, and pressing component 22 (which can be a nut or spring 23). Prepare installation tools such as screwdrivers and wrenches.

[0034] Connect the support plate 1 to the support bracket 3 via the hanger 2, ensuring the top of the hanger is securely fixed to the support bracket. Install a lower rubber pad 11 at the bottom of the support plate to increase the stability and protection of the cable tray 100 during placement. Fix the lower mounting plate 41 to the bottom of the support plate with bolts 43, ensuring the threaded holes on the lower mounting plate match the threaded holes on the bottom of the support plate. Install the rotating disk 42 in the middle of the lower mounting plate 41, ensuring the rotating disk can rotate freely. Ensure there are sufficient through holes on the support plate and the lower rubber pad so that the rotating disk can pass through and place the cable tray.

[0035] Place the cable tray 100 on the rotating disk 42 and adjust its position and orientation using the disk. Slide the upper pressure plate 21 onto the hanger rod 2, ensuring it can move freely up and down. If a nut is chosen as the clamping component, thread the nut onto the upper end of the hanger rod and rotate it to move it vertically downwards along the hanger rod until the upper pressure plate 21 abuts against the top of the cable tray. If a spring 23 is chosen as the clamping component, sleeve the spring onto the hanger rod, ensuring it is positioned between the support and the upper pressure plate. The spring force will drive the upper pressure plate towards the support plate, thus abutting against the cable tray. Install a rubber pad 211 at the bottom of the upper pressure plate to enhance protection for the cable tray.

[0036] Check that all connections are secure to ensure the cable tray is stably suspended from the support plate. Adjust the position and angle of the cable tray using the rotating disc to meet actual needs. Regularly inspect all components for wear and looseness, replacing or tightening them as needed. Clean dust and debris from the cable tray and its surroundings to maintain cleanliness.

[0037] If it is determined that the cable tray no longer needs angle adjustment, the rotating component can be disassembled and used for angle adjustment of other cable trays, achieving multiple uses and reducing the company's operating costs.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
