Description

Technical Field

[0001] This utility model relates to the field of road equipment technology, and in particular to a rotatable light pole mechanism that is easy to install and maintain. Background Technology

[0002] Traditional municipal light poles often have fixed welded structures for the cantilever and the main body of the pole. This means that maintenance and angle adjustment of the lights or cameras require aerial work platforms or climbing equipment, which poses problems such as high safety risks, low operational efficiency, and significant traffic disruption. In addition, some rotatable light poles use a simple pivot design, but after long-term use, friction can cause the rotation to become stuck, and there is a lack of an effective locking mechanism. In strong winds, the cantilever is prone to shifting, affecting the stability of the lighting and its service life. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as "fixed welded structures that require reliance on aerial work platforms or climbing equipment for lamp maintenance or angle adjustment, resulting in high safety risks, low operational efficiency, and significant traffic disruption; and the fact that some rotatable lamp posts use simple pivot designs that are prone to jamming due to friction after long-term use, lack an effective locking mechanism, and are susceptible to cantilever shifting in strong winds, affecting lighting stability and lifespan." Therefore, this invention proposes a rotatable lamp post mechanism that is easy to install and maintain.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotatable light pole mechanism that is easy to install and maintain includes: a fixed rod, a lower light pole fixedly mounted on the upper end of the fixed rod, an upper light pole mounted above the lower light pole, the upper light pole and the lower light pole being connected by a flange, and a rotating component being provided inside the upper light pole;

[0006] The rotating component includes:

[0007] A rotary bearing is installed inside the upper lamp post;

[0008] The slewing bearing is equipped with a starter motor for driving its operation, and a cantilever rod is installed at the output end of the slewing bearing.

[0009] As a preferred embodiment of the rotatable lamp post mechanism for easy installation and maintenance described in this utility model, the upper lamp post has an installation groove for use with the cantilever rod, the lower lamp post has a core tube rotatably mounted on it, and the core tube has an insertion groove for the lower end of the cantilever rod to be inserted into.

[0010] As a preferred embodiment of the rotatable lamp post mechanism described in this utility model, which is easy to install and maintain, the lower end of the cantilever rod is provided with an auxiliary rotating component for reducing friction between the inner wall of the lower lamp post and the outer wall of the core tube.

[0011] As a preferred embodiment of the rotatable lamp post mechanism that is easy to install and maintain according to this utility model, the auxiliary rotating component includes a connecting cavity opened at the lower end of the core tube, a rotating groove opened in the lower lamp post, a fixed steel plate bracket welded to the inner wall of the core tube installed in the connecting cavity, and a rotating auxiliary bearing that is tightly fitted to the inner wall of the lower lamp post at the lower end of the fixed steel plate bracket.

[0012] As a preferred embodiment of the rotatable lamp post mechanism that is easy to install and maintain according to this utility model, the upper lamp post is provided with a connecting groove, and a limiting component is provided in the connecting groove to prevent the cantilever rod from rotating due to external forces.

[0013] As a preferred embodiment of the rotatable lamp post mechanism that is easy to install and maintain according to this utility model, the limiting component includes a ratchet fixedly mounted on the cantilever rod, a sliding groove is provided inside the upper lamp post, a cylinder is fixedly mounted on the upper lamp post, and a pawl is fixedly mounted at the output end of the cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The cantilever arm is precisely rotated and adjusted by the coordinated drive of the slewing bearing and the starter motor. The rolling contact of the auxiliary rotating bearing in the rotating groove significantly reduces the frictional resistance between the core tube and the inner wall of the lower lamp post, improving the smoothness of rotation and reducing wear. The dynamic limiting structure, which is driven by a cylinder to engage the pawl and the ratchet, reliably locks the position of the cantilever arm in the non-adjustment state, effectively resisting external forces such as wind loads.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Reference Figures 1-5 A rotatable light pole mechanism for easy installation and maintenance includes a fixed rod 101, a lower light pole 102 fixedly mounted on the upper end of the fixed rod 101, an upper light pole 103 mounted above the lower light pole 102, and the upper light pole 103 and the lower light pole 102 connected by a flange 201. A rotating component 202 is disposed within the upper light pole 103, and the rotating component 202 includes a rotary bearing 2023 disposed inside the upper light pole 103; a starter motor 202 is disposed on the rotary bearing 2023 for driving its operation. 4. A cantilever rod 2022 is installed at the output end of the rotary bearing 2023. An installation groove 2021 for use with the cantilever rod 2022 is opened in the upper lamp post 103. A core tube 2025 is rotatably installed on the lower lamp post 102. An insertion groove 203 for the lower end of the cantilever rod 2022 to be inserted is opened on the core tube 2025. In use, the rotary bearing 2023 can be driven to rotate by starting the motor 2024, which in turn drives the cantilever rod 2022 to rotate. The direction of the cantilever rod 2022 can be adjusted according to the actual situation.

[0025] Reference Figures 3-4Considering that the inner wall of the core tube 2025 will rub against the inner wall of the lower lamp post 102 during rotation, an auxiliary rotating component 204 is required at the lower end of the cantilever rod 2022 to reduce the friction between the inner wall of the lower lamp post 102 and the outer wall of the core tube 2025. The auxiliary rotating component 204 includes a connecting cavity 2041 opened at the lower end of the core tube 2025, a rotating groove 2042 opened in the lower lamp post 102, a fixed steel plate bracket 2043 welded to the inner wall of the core tube 2025 installed in the connecting cavity 2041, and a rotating auxiliary bearing 2044 that fits tightly against the inner wall of the lower lamp post 102 at the lower end of the fixed steel plate bracket 2043.

[0026] Reference Figure 5 To prevent the cantilever 2022 from rotating due to external forces when it is not needed, a connecting groove 205 is provided in the upper lamp post 103. A limiting component 206 is provided in the connecting groove 205 to prevent the cantilever 2022 from rotating due to external forces. The limiting component 206 includes a ratchet 2061 fixedly mounted on the cantilever 2022, a sliding groove 2062 provided in the upper lamp post 103, a cylinder 2063 fixedly mounted on the upper lamp post 103, and a pawl 2064 fixedly mounted at the output end of the cylinder 2063.

[0027] In summary, the working principle of this solution is as follows:

[0028] The starter motor 2024 drives the rotary bearing 2023 to rotate, causing the cantilever rod 2022 to rotate within the mounting groove 2021. At this time, the core tube 2025 rotates synchronously with the cantilever rod 2022, and the rotary auxiliary bearing 2044 at its lower end rolls within the rotary groove 2042, significantly reducing the friction between the core tube 2025 and the inner wall of the lower lamp post 102. After adjustment, the cylinder 2063 pushes the pawl 2064 to move along the slide groove 2062 and engage with the ratchet 2061 tooth groove on the cantilever rod 2022, achieving mechanical locking and effectively resisting external forces such as wind, ensuring the stable positioning of the cantilever rod 2022.

[0029] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
