Description

Technical Field

[0001] The invention relates to the technical field of street lamps, and in particular to a double-pole street lamp cantilever. Background Art

[0002] In the lighting system of urban roads, the design and stability of street lamps are crucial to ensure traffic safety and public safety. Traditional conventional street lamps often face serious structural safety problems in windy weather, especially double-pole street lamps. Under the action of strong winds, the lamp arms of double-pole street lamps are easily affected by wind pressure due to their large force-bearing area, causing the lamp arms to bend, break, or even collapse, thus posing a greater safety hazard. This problem may not only cause damage to the street lamp itself, but also pose a threat to the safety of passing vehicles and pedestrians, especially in windy areas or extreme weather.

[0003] The design of double-pole street lamps usually adopts a fixed lamp arm structure, which has a simple structure and low cost, but lacks adaptability to windy weather. In severe weather conditions, the force of wind on the lamp arm of double-pole street lamps cannot be ignored. When the force-bearing area of ​​the lamp arm is large, the pressure brought by the wind is more significant, causing deformation or damage to the lamp arm. Especially in an environment with high wind speed, it is difficult for the structure of conventional street lamps to ensure sufficient stability and wind resistance.

[0004] Therefore, how to design a street lamp structure that can remain stable and prevent damage in windy weather while ensuring the functionality and safety of the lamp has become an important issue in the current technical field. Summary of the invention

[0005] In view of this, the present invention proposes a double-pole street lamp cantilever, aiming to improve the safety and reliability of the street lamp by designing a retractable cantilever structure.

[0006] The technical solution of the present invention is implemented as follows: the present invention provides a double-pole street lamp cantilever, comprising: a fixed frame, a first linear guide rail, a first slider, a sliding seat, a street lamp cantilever and a driving device. The first linear guide rail is fixedly installed on the top of the fixed frame, the first linear guide rail is vertically arranged, the first slider is slidably arranged on the first linear guide rail, and the two sliding seats are symmetrically arranged on the horizontal sides of the first linear guide rail. The two sliding seats can rotate along the horizontal axis relative to the fixed frame, and a street lamp cantilever is slidably arranged in each sliding seat. The end of the street lamp cantilever close to the first linear guide rail is hinged to the first slider. The driving device is fixed on the fixed frame, and the driving device can drive the first slider to reciprocate linearly along the first linear guide rail.

[0007] In the above implementation manner, the sliding seat is used as a fulcrum to form a lever effect, and the street lamp cantilever close to the low linear guide is driven up and down to achieve the adjustment of the up and down position and the horizontal extension distance of the lighting end of the street lamp cantilever of the principle first linear guide. When the rising distance of the street lamp cantilever close to the first linear guide is relatively large, a certain storage effect of the street lamp cantilever can be achieved, thereby protecting the street lamp in bad weather. At the same time, this structure can realize the adjustment of the illumination range and angle of the street lamp, and has good application prospects.

[0008] In some embodiments, the driving device includes a driving motor and a first screw rod, the first screw rod is parallel to the first linear guide rail, the first screw rod is threadedly connected to the first slider, the driving motor is fixed on the fixing frame, and the driving motor can drive the first screw rod to rotate.

[0009] In the above embodiments, the driving device uses a motor and a first screw rod, and uses threaded matching to adjust the up and down sliding motion of the first slider, which has a simple adjustment method and can also perform position locking.

[0010] In some embodiments, two second linear guides and a second slider are also included, and the two second linear guides are symmetrically arranged on both sides of the first linear guide, and the two second linear guides are coplanar with the first linear guide. The lower ends of the second linear guides are fixedly connected to the fixed frame, and a second slider is slidably arranged on each second linear guide. The sliding seat is hinged to the side of the second slider, and the driving device can drive the second slider to reciprocate linearly along the second linear guide. The movement direction of the second slider is opposite to the movement direction of the first slider.

[0011] In the above implementation, since the position of the fulcrum remains unchanged when the sliding seat is used as the fulcrum, only the position of the driving end is changed, the spatial adjustment effect of the street lamp cantilever, especially the adjustment of the width distance in the horizontal direction is relatively limited. Therefore, in order to achieve a better storage adjustment effect, a second slider is used to adjust the position of the sliding seat. For example, when the second slider is driven to a position close to the first linear guide rail, the street lamp cantilever can be stored to be close to parallel with the first linear guide rail. At this time, the storage effect of the street lamp cantilever is the best.

[0012] In some embodiments, the driving device further includes two second screw rods, which are respectively parallel to the two second linear guide rails, each second slider is threadedly connected to a second screw rod, and the driving motor can drive the two second screw rods to rotate.

[0013] In order to adjust the position of the second slider, the second slider is driven by the second screw rod and the threaded joint, which has the advantages of simple driving method and driving structure and can be locked in position.

[0014] In some embodiments, the second screw rod has the same thread direction as the first screw rod, and the rotation direction of the second screw rod is opposite to the rotation direction of the first screw rod.

[0015] In order to achieve faster position adjustment, the second screw has the same thread as the first screw and rotates in opposite directions, which can achieve the fastest position adjustment. When the first screw and the second screw rotate synchronously in opposite directions, if the first slider rises and moves away from the fixed frame, the second slider will move toward the fixed frame; if the first slider falls and approaches the fixed frame, the second slider will move away from the fixed frame. The above two adjustment situations correspond to the storage and deployment of the street light cantilever respectively.

[0016] In some embodiments, the driving device also includes an active bevel gear and a driven bevel gear, the first screw rod is coaxially keyed to the active bevel gear, the second screw rod is coaxially keyed to the driven bevel gear, the active bevel gear and the two driven bevel gears are meshed with each other, and the first screw rod is drivingly connected to the driving shaft of the driving motor.

[0017] In the above implementation, a specific and implementable adjustment drive structure is provided. When the driving motor drives the first screw rod to rotate clockwise, the two second screw rods will rotate counterclockwise. The above observation directions are all from the direction away from the fixed frame along the corresponding first screw rod or second screw rod axial direction toward the fixed frame.

[0018] In some embodiments, the included angle between the second linear guide rail and the first linear guide rail is 30-60°.

[0019] In some embodiments, the angle between the second linear guide rail and the first linear guide rail is 30°.

[0020] In some embodiments, the included angle between the second linear guide rail and the first linear guide rail is 45°.

[0021] In some embodiments, the included angle between the second linear guide rail and the first linear guide rail is 60°.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The double-pole street lamp cantilever proposed in the present invention adopts a retractable cantilever structure, which significantly improves the safety and reliability of the street lamp under adverse weather conditions. Through the sophisticated design of the linear guide rail and slider system, combined with the adjustment function of the drive device, the street lamp cantilever can be accurately adjusted in the vertical and horizontal directions, especially in extreme weather such as strong winds, which can effectively reduce the impact of wind on the street lamp structure, thereby reducing the risk of damage caused by wind.

[0033] like Figure 1 As shown, combined Figure 2-3 The double-pole street lamp cantilever of the present invention comprises: a fixed frame 1, a first linear guide rail 2, a first slider 3, a sliding seat 4, a street lamp cantilever 5 and a driving device 6. The first linear guide rail 2 is fixedly installed on the top of the fixed frame 1. The first linear guide rail 2 is vertically arranged. The first slider 3 is slidably arranged on the first linear guide rail 2. The two sliding seats 4 are symmetrically arranged on both horizontal sides of the first linear guide rail 1. The two sliding seats 4 can rotate along the horizontal axis relative to the fixed frame 1. A street lamp cantilever 5 is slidably arranged in each sliding seat 4. The end of the street lamp cantilever 5 close to the first linear guide rail 2 is hinged to the first slider 3. The driving device 6 is fixed on the fixed frame 1. The driving device 6 can drive the first slider 3 to reciprocate along the first linear guide rail 2.

[0034] In the above embodiment, a sliding channel is provided on the surface of the sliding seat 4, and the sliding channel is used to slide and support the cantilever part of the street lamp cantilever 5. The driving end of the street lamp cantilever 5 is hinged to the first slider 3, and the rotating shaft of the hinge connection is parallel to the rotating shaft of the sliding seat 4. When the driving device 6 drives the first slider 3 to rise or fall, the end street lamp of the street lamp cantilever 5 approaches the sliding seat 4 as the first slider 3 rises, and moves away from the sliding seat 4 as the first slider 3 falls. At the same time, due to the rise and fall of the cantilever driving end, the end street lamp of the street lamp cantilever 5 also rises and falls and changes the illumination angle. This process can realize the angle adjustment, horizontal position adjustment and height adjustment of the street lamp cantilever, thereby achieving a certain degree of storage and deployment effect.

[0035] In some embodiments, the driving device 6 includes a driving motor 61 and a first screw rod 62. The first screw rod 62 is parallel to the first linear guide rail. The first screw rod 62 is threadedly connected to the first slider 3. The driving motor 61 is fixed on the fixed frame 1. The driving motor 61 can drive the first screw rod 62 to rotate.

[0036] In the above embodiment, the driving motor 61 drives the first screw rod 62 to rotate, thereby realizing the ascent and descent of the first sliding block threadably connected to the first screw rod 62 .

[0037] In the above embodiments, the first linear guide rail 2 includes a guide rod arranged in a vertical direction for limiting the first slider 3 , so as to prevent the first slider 3 from rotating along with the rotation of the first screw rod 62 .

[0038] In some embodiments, it also includes two second linear guides 7 and a second slider 8, the two second linear guides 7 are symmetrically arranged on both sides of the first linear guide 2, the two second linear guides 7 are coplanar with the first linear guide 2, the lower ends of the second linear guides 7 are fixedly connected to the fixed frame 1, and a second slider 8 is slidably arranged on each second linear guide 7. The sliding seat 4 is hinged to the side of the second slider 8. The driving device 6 can drive the second slider 8 to reciprocate linearly along the second linear guide 7, and the movement direction of the second slider 8 is opposite to the movement direction of the first slider 3.

[0039] In the above embodiment, during the rising and falling process of the first slide block 3, if the position of the slide seat 4 relative to the first linear guide rail 2 remains unchanged, the adjustment space of the motion trajectory of the end of the street lamp cantilever 5 is relatively limited. In order to achieve a larger adjustment range, a second linear guide rail 7 and a second slide block 8 are provided, and the driving device 6 drives the second slide block 8 to move along the second linear guide rail 7. The second linear guide rail 7 is tilted upward at one end away from the first linear guide rail 2, and the slide seat 4 is rotatably provided on the side of the second slide block 8. When the second slide block 8 moves along the second linear guide rail 7, it is equivalent to that the position of the slide seat 4 relative to the first linear guide rail 2 changes. At the same time, the movement direction of the second slide block 8 is opposite to the movement direction of the first slide block 3. At this time, the adjustable range of the street lamp structure at the end of the street lamp cantilever 5 is greatly expanded.

[0040] In the above embodiment, the movement direction of the second slider 8 is opposite to the movement direction of the first slider 3 , which means that when the second slider 8 approaches the fixing frame 1 , the first slider 3 moves away from the fixing frame 1 .

[0041] In some embodiments, the driving device 6 further includes two second screw rods 63 , which are respectively parallel to the two second linear guide rails 7 , each second slider 8 is threadedly connected to a second screw rod 63 , and the driving motor 61 can drive the two second screw rods 63 to rotate.

[0042] In the above embodiment, a solution for driving the second slider 8 to move along the second linear guide rail 7 is provided, including providing a second screw rod 63, and the second screw rod 63 is driven by a driving motor.

[0043] In some embodiments, the second screw rod 63 has the same thread direction as the first screw rod 62 , and the rotation direction of the second screw rod 63 is opposite to the rotation direction of the first screw rod 62 .

[0044] In the above embodiments, in order to realize the driving mode of the first slider 3 and the second slider 8 in opposite directions, screw rods with the same thread but different rotation directions are used for rotation driving, which has a simple structure and is easy to realize.

[0045] In some embodiments, the driving device 6 also includes an active bevel gear 64 and a driven bevel gear 65, the first screw rod 62 is coaxially keyed to the active bevel gear 64, the second screw rod 63 is coaxially keyed to the driven bevel gear 65, the active bevel gear 64 is meshed with the two driven bevel gears 65, and the first screw rod 62 is transmission-connected to the driving shaft of the driving motor 61.

[0046] In the above embodiments, in order to realize the reverse rotation between the first screw rod 62 and the second screw rod 63, an active bevel gear 64 and a passive bevel gear 65 are used to realize synchronous drive and reverse rotation by meshing. The driving structure is simple and reliable, and the number of driving motors 61 can be saved, which is beneficial to reducing energy consumption and equipment costs.

[0047] In some embodiments, the angle between the second linear guide rail 7 and the first linear guide rail 2 is 30-60°.

[0048] In the above embodiments, in order to achieve better driving and storage effects, the angle between the second linear guide rail 7 and the first linear guide rail 2 is optimally 30-60°.

[0049] In some embodiments, the angle between the second linear guide rail 7 and the first linear guide rail 2 is 30°.

[0050] In the above embodiments, when the included angle between the second linear guide rail 7 and the first linear guide rail 2 is 30°, it is mainly used in the usage scenario where precise adjustment of the direction and angle of the illumination is required.

[0051] In some embodiments, the angle between the second linear guide rail 7 and the first linear guide rail 2 is 45°.

[0052] In the above embodiments, when the included angle between the second linear guide rail 7 and the first linear guide rail 2 is 45°, both storage and angle adjustment can be taken into consideration.

[0053] In some embodiments, the angle between the second linear guide rail 7 and the first linear guide rail 2 is 60°.

[0054] In the above embodiments, when the included angle between the second linear guide rail 7 and the first linear guide rail 2 is 60°, a faster and greater storage effect can be achieved.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
