Description

Technical Field

[0001] This utility model relates to the field of street light technology, specifically a street light pole with a prestressed locking device. Background Technology

[0002] Streetlight poles, as core supporting components of urban lighting systems, are widely used in various scenarios such as urban roads, highways, and parks. Their main function is to fix the lamps and ensure stable lighting range, meeting the installation and usage needs of daily lighting. However, existing streetlight pole technologies have significant shortcomings. The connection between traditional poles and embedded bases often relies on simple bolt fixing, which does not form an effective fixation. Under long-term exposure to external forces such as wind loads, the connection is prone to loosening, leading to a decrease in the overall stability of the pole. Furthermore, the connection has weak resistance to bending and fracture, making it difficult to cope with complex outdoor environments. Therefore, we propose a streetlight pole with a prestressed locking device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a street light pole with a prestressed locking device, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a street light pole with a prestressed locking device, comprising: An embedded base is provided at the bottom of the embedded base, and the base plate is fixedly engaged with the ground through an adapter rod; A light pole assembly is disposed on the top of the pre-embedded base.

[0025] Working principle: Install the street light pole with prestressed locking device correctly according to the diagram. Fix the bottom plate 7 of the embedded base 1 to the ground through the matching plug. The reinforcing rib 9 inside the embedded base 1 enhances its own bending resistance and provides a connection foundation for the built-in column 12 of the connecting cylinder 2. Then, insert the built-in column 12 at the bottom of the connecting cylinder 2 into the embedded base 1, and at the same time, insert the built-in column 11 at the top of the connecting cylinder 2 into the bottom of the light pole 4. Make the elastic pads 16 at the top and bottom of the connecting ring 10 fit against the flange 18 at the bottom of the light pole 4 and the flange 6 at the top of the embedded base 1, respectively. Then, arrange the six high-strength bolts 3 in a circular array and pass them through the connecting hole 8 of the flange 6, the connecting hole 17 of the connecting ring 10, and the flange in sequence. Using a torque wrench or hydraulic tensioner, the preload of the high-strength bolt 3 is precisely controlled through the connecting hole 3 19 of flange 2 18, generating axial tension in the high-strength bolt 3. The preload is then transferred to flange 1 6, connecting ring 10, and flange 2 18 via elastic pad 16, creating pre-stress at the connection points. Simultaneously, double nuts are used to lock the high-strength bolt 3 to prevent loosening, achieving pre-stress locking. Finally, the protective cover 5 is slid down, and the fixing hole 24 on its side wall is connected to the fixing hole 22 on the mounting plate 20 on the side wall of the lamp post 4 using adapter screws. This allows the protective cover 5 to cover flange 1 6 and flange 2 18, with the top of the inner part of the protective cover 5 fitting against the rubber ring 21 of the mounting plate 20, completing the overall assembly. This achieves pre-stress locking while providing protection.
