Description

Technical Field

[0001] This utility model relates to the field of street light crossarms, and more specifically, to a quick-installation street light crossarm. Background Technology

[0002] In accordance with relevant national policies, most of the existing streetlights have undergone comprehensive treatment. The functions of the previous streetlights have been combined according to actual needs, and redundant, old, and energy-intensive streetlights have been removed or newly built in order to beautify the road landscape and reduce the waste of space resources.

[0003] Integrated poles are generally multi-functional poles that combine multiple functions into one. Through technological innovation and comprehensive design, they integrate various urban service and management poles, such as public security monitoring poles, traffic signal poles, communication poles, traffic sign poles, and street light poles, into a single pole based on a street light pole.

[0004] Electronic monitoring equipment, signs, and traffic lights are typically suspended and installed on the crossarms of streetlight poles. The main function of the crossarms is to provide a fixed installation location for these devices and facilities. They mainly consist of crossarm flanges, reinforcing ribs, the crossarm itself, and brackets. The crossarms appear as a separate structural component and are connected and fixed to the streetlight pole using appropriate fasteners (bolts, nuts, spring washers, flat washers).

[0005] The crossarms on existing integrated poles mainly consist of the pole body, flanges, reinforcing ribs, and mounting brackets for various equipment. The crossarms require corresponding flanges with multiple mounting holes. To strengthen the connection between the crossarm and flange, multiple reinforcing ribs are also included, and these are welded together to secure the crossarm, flange, and ribs. Similarly, streetlight poles also require corresponding flanges and reinforcing ribs welded to the pole body for installation with the crossarms. These flanges and reinforcing ribs on the pole body must be fabricated separately and welded to the pole body. This makes the pole body fabrication relatively complex and cumbersome, increases welding steps, and increases the workload for both workers and designers, significantly increasing the overall design and manufacturing costs of the integrated pole.

[0006] In addition, when the crossarm is fixed to the connecting flange on the light pole, multiple fasteners (bolts, nuts, spring washers, flat washers) are usually required to ensure a firm connection between the crossarm and the light pole. This not only increases the installation efficiency and labor intensity of the installers, but also increases the corresponding cost. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] This utility model provides, for example Figure 1-11 The diagram shows a quick-installation street light crossarm, comprising a crossarm body 2 installed at the main pole 1 of the street light. An installation unit is provided at the crossarm body 2, the installation unit having a U-shaped cross-section. The installation unit includes an installation plate 3 and a surrounding plate 4. The surrounding plate 4 is integrally bent and formed with the installation plate 3. The installation plate 3 has a first straight side 3.1, and the surrounding plate 4 has a second straight side 4.1, which is parallel to and fixedly connected to the first straight side 3.1. The length of the second straight side 4.1 is less than or equal to one-third of the length of the first straight side 3.1. The installation plate 3 has a through hole through which the crossarm body 2 passes and is fixedly connected to the installation plate 3. Multiple reinforcing ribs 3.2 are provided between the crossarm body 2 and the installation plate 3. The crossarm body 2 can pass through the main pole 1 and be fixedly connected to it. The installation plate 3 can abut against the main pole 1, and the surrounding plate 4 can partially surround the main pole 1.

[0044] A fixing through hole 1.2 is provided at the main rod 1, and a nut 1.3 is provided in the fixing through hole 1.2. A bolt 5 is provided at the mounting unit to fix and connect the surrounding plate 4 and the nut 1.3. The surrounding plate 4 has a bolt through hole 4.2 that mates with the bolt 5. The mounting unit can be in an initial installation state and an installed state. In the initial installation state, the cross arm body 2 passes through the main rod 1, and the first straight edge 3.1 and the second straight edge 4.1 are both in a vertical state. In the installed state, the cross arm body 2 passes through the main rod 1, the first straight edge 3.1 and the second straight edge 4.1 are both in a horizontal state, the surrounding plate 4 partially surrounds the main rod 1, and the bolt 5 is fixedly connected to the nut 1.3. An installation through hole 1.1 is provided at the main rod 1, and the end of the cross arm body 2 can pass through the installation through hole 1.1. The fixing through hole 1.2 is a hexagonal hole, and the nut 1.3 is a hexagonal nut. A monitoring camera 6 is installed at the cross arm body 2. The main rod 1 has a first threading hole 1.4 and a waterproof plug 1.5. The cross arm body 2 has multiple second threading holes 2.1.

[0045] Working Principle: The street light crossarm of this application is easy to install. By rotating the angle of the crossarm body, the mounting plate and the surrounding plate are tightly attached to the main pole, and then fixed with bolts to complete the installation, greatly facilitating the installation and disassembly of workers. It reduces the number of connecting flanges on the main pole, reduces corresponding welding processes, reduces material usage, saves on pole manufacturing costs and time, and improves production efficiency. It can be retrofitted later according to actual needs, reducing the investment cost and installation cost of new poles. Furthermore, it reduces the welding area and significantly reduces the number of fasteners used, saving costs while making disassembly and assembly faster and more convenient, and greatly reducing the workload of workers.

[0046] During installation of the crossarm body, first ensure that the first straight edge of the mounting plate and the second straight edge of the surrounding plate are both horizontal. Keep the crossarm body perpendicular to the main pole. Insert the crossarm body into the mounting through-hole on the main pole, then rotate the crossarm body 90 degrees to make both the first straight edge of the mounting plate and the second straight edge of the surrounding plate vertical, thus ensuring both the mounting plate and the surrounding plate are flush with the main pole. Next, use bolts passing through the bolt through-holes in the surrounding plate to secure it to the hexagonal nuts welded to the main pole, thus fixing the surrounding plate to the main pole. To disassemble the crossarm body, first remove the bolts securing the surrounding plate to the main pole, then rotate the crossarm body 90 degrees to detach the surrounding plate from the outer surface of the main pole. Finally, remove the crossarm body from the mounting through-hole.

[0047] The streetlight crossarm of this application can be installed on main poles of different shapes, such as cylindrical poles, square poles, hexagonal equal-diameter poles, and hexagonal tapered poles. The shape of the installation unit changes depending on the cross-sectional shape of the main pole. For example, for a hexagonal main pole, the installation unit needs to be made into a quadrilateral shape that matches the cross-sectional shape of the hexagonal main pole. For the crossarm body of a cylindrical main pole, the installation unit needs to be made into a pentagon, with each side of the pentagon tangent to the cylindrical main pole. Furthermore, the crossarm body can be added later according to actual needs. Fixing through holes and hexagonal holes are opened at the main pole, and hexagonal nuts are welded into the hexagonal holes, thereby reducing the investment cost and installation cost of new poles.

[0048] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
