Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to rotating lighting equipment and a crane. Background Art

[0002] Cranes are essential mechanical equipment for the construction of infrastructure, wind power, nuclear power, etc. The boom, as a key and important component of the crane, must meet the requirements of hoisting conditions under poor lighting conditions at night. Therefore, the lighting angle of the boom lighting equipment needs to be adjustable.

[0003] In the related art, the lighting angle of the lighting equipment of the crane arm is usually adjusted in the following two ways: the first is manual adjustment of the lighting angle. The lighting angle can only be adjusted before the lifting construction and cannot be adjusted during the construction process. In addition, the crane arm is at a large distance from the ground, and a ladder is required to adjust the lighting angle, which is inconvenient and the work is dangerous and difficult. The second is motor adjustment of the lighting angle. The motor has a high speed and needs to be used in conjunction with a gear pair. Under relatively harsh outdoor working conditions, the gear pair is easily damaged and an additional sealing structure needs to be added. The structure is relatively complex and the cost is high.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0042] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0043] According to an embodiment of the present invention, on one hand, a rotating lighting device 1 is provided. The rotating lighting device 1 includes a fixing frame 100 , a retractable driving member 200 and a lighting assembly 300 .

[0044] The lighting assembly 300 includes a lamp 310, a support arm 320, and a connecting rod 330. The support arm 320 is rotatably mounted on the fixing frame 100 and connected to the connecting rod 330. The rotation axis of the support arm 320 extends along the axial direction of the support arm 320, and the lamp 310 is connected to the support arm 320. One end of the driving member 200 is hinged to the fixing frame 100, and the other end of the driving member 200 is hinged to the connecting rod 330.

[0045] Specifically, the driving member 200 includes a shell 210 and a piston 220. The shell 210 has a fixed end 211 and an insertion end 212 that are relatively arranged. The fixed end 211 is rotatably arranged on the fixed frame 100. The piston 220 is inserted into the shell 210 from the insertion end 212, and the piston 220 can move telescopically relative to the shell 210 along its axial direction. The end of the piston 220 away from the shell 210 is set as a movable end 221.

[0046] For example, the driving member 200 may be a pneumatic cylinder or an oil cylinder. The connecting rod 330 and the support arm 320 may be an integrally formed structure to increase the connection strength between the connecting rod 330 and the support arm 320 and to allow for simultaneous assembly, thereby improving assembly efficiency.

[0047] When the piston 220 of the driving member 200 is extended and retracted relative to the housing 210, it can drive one end of the connecting rod 330 to displace. Since the other end of the connecting rod 330 is fixedly connected to the support arm 320, and the support arm 320 is rotatably connected to the fixing frame 100, the connecting rod 330 also rotates around the other end of the connecting rod 330, thereby driving the support arm 320 to rotate relative to the fixing frame 100, and the lighting assembly 300 device rotates relative to the fixing frame 100 along with the support arm 320.

[0048] The rotating lighting device 1 of the embodiment of the present invention can drive the lighting assembly 300 to rotate automatically by controlling the extension and retraction of the piston 220 of the driving member 200 relative to the housing 210. It can not only adjust the lighting angle according to needs to ensure a good lighting effect, but also can be used to observe the extension and retraction state of the crane arm 2, and can also be used to illuminate the hoisted objects, which can effectively improve the working adaptability of the crane, and does not require manual adjustment, reducing working risks. The angle adjustment is more flexible, and there is no need to set a gear pair structure. It has a simple structure, high reliability, and is not easy to damage. It does not require an additional sealing structure, which can reduce costs.

[0049] like Figure 5 As shown, in the technical solution of this embodiment, the fixing frame 100 includes a fixing plate 110, a plurality of brackets 120, a first rotating shaft 130 and a first anti-wear elastic member 140. Among them, the brackets 120 and the fixing plate 110 can be an integrally formed structure to increase structural strength and improve assembly efficiency.

[0050] Multiple brackets 120 are arranged on the fixed plate 110, and each bracket 120 is provided with a first rotating hole 121, and brackets 120 are respectively provided on two opposite radial sides of the fixed end 211. The fixed end 211 is provided with a second rotating hole 213, the first rotating shaft 130 is inserted into the first rotating hole 121 and the second rotating hole 213, and the first anti-wear elastic member 140 is provided between the fixed end 211 and the bracket 120.

[0051] The first anti-wear elastic member 140 can be made of a silicone or rubber member with excellent elasticity and wear resistance. Furthermore, the first rotating shaft 130 can include a first shaft body 132, a first stop edge 133, and a first latch 131. The first stop edge 133 is constructed at one end of the first shaft body 132. The first shaft body 132 is constructed with a first through hole, and the first latch 131 is pluggable and inserted into the first through hole. The first shaft body 132 is inserted into the first rotating hole 121 and the second rotating hole 213. The cooperation between the first stop edge 133 and the first latch 131 can define the position of the first rotating shaft 130, ensuring the stability of the relative positions between the first rotating shaft 130, the fixed end 211, and the bracket 120.

[0052] By setting up the bracket 120, the fixed end 211 and the first rotating shaft 130, the fixed end 211 can be rotatably connected to the fixed frame 100, and the fixed end 211 and the fixed plate 110 can be spaced apart to avoid the fixed end 211 interfering with the movement of the fixed end 211, thereby improving the movement reliability of the driving member 200.

[0053] By setting the first anti-wear elastic member 140, there is no direct contact between the bracket 120 and the fixed end 211, which can reduce the noise generated when the bracket 120 and the fixed end 211 rotate relative to each other, and prevent wear between the bracket 120 and the fixed end 211, thereby extending the service life of the bracket 120 and the driving member 200.

[0054] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the rotating lighting device 1 also includes a second rotating shaft 400 and a second anti-wear elastic member 500, the connecting rod 330 is provided with a third rotating hole 331, and the movable end 221 is provided with a fourth rotating hole 222, the second rotating shaft 400 is inserted into the third rotating hole 331 and the fourth rotating hole 222, and the second anti-wear elastic member 500 is provided between the connecting rod 330 and the movable end 221.

[0055] The second anti-wear elastic member 500 can be a silicone or rubber member with excellent elasticity and wear resistance. Furthermore, the second rotating shaft 400 can include a second shaft body 420, a second stop edge 430, and a second latch 410. The second stop edge 430 is configured at one end of the second shaft body 420. The second shaft body 420 is configured with a second through hole, and the second latch 410 is pluggable and inserted into the second through hole. The second shaft body 420 is inserted into the third rotating hole 331 and the fourth rotating hole 222. The cooperation between the second stop edge 430 and the second latch 410 can define the position of the second rotating shaft 400, ensuring the relative stability between the second rotating shaft 400, the connecting rod 330, and the movable end 221.

[0056] By connecting the connecting rod 330, the movable end 221, and the second rotating shaft 400, a rotatable connection between the connecting rod 330 and the movable end 221 is achieved. By providing the second anti-wear elastic member 500, there is no direct contact between the connecting rod 330 and the movable end 221, which can reduce noise generated when the connecting rod 330 and the movable end 221 rotate relative to each other, prevent wear between the connecting rod 330 and the movable end 221, and extend the service life of the connecting rod 330 and the movable end 221.

[0057] Furthermore, the first anti-wear elastic member 140 is sleeved on the first rotating shaft 130 , or the second anti-wear elastic member 500 is sleeved on the second rotating shaft 400 , or the first anti-wear elastic member 140 is sleeved on the first rotating shaft 130 , and the second anti-wear elastic member 500 is sleeved on the second rotating shaft 400 .

[0058] In this way, the first rotating shaft 130 can fix the relative positions of the first anti-wear elastic member 140, the bracket 120, and the fixed end 211, eliminating the need for an additional fixing structure for the first anti-wear elastic member 140. This prevents the first anti-wear elastic member 140 from being separated from the bracket 120 and the fixed end 211, thereby ensuring the wear and noise suppression effects. The second rotating shaft 400 can fix the relative positions of the second anti-wear elastic member 500, the connecting rod 330, and the movable end 221, eliminating the need for an additional fixing structure for the second anti-wear elastic member 500. This prevents the second anti-wear elastic member 500 from being separated from the connecting rod 330 and the movable end 221, thereby ensuring the wear and noise suppression effects.

[0059] like Figure 3 As shown, in the technical solution of this embodiment, the fixing frame 100 includes a fixing plate 110, a limiting seat 150 and a limiting cover 160. The fixing plate 110 and the limiting seat 150 can be an integrally formed structure to increase structural strength and improve assembly efficiency.

[0060] The limiting seat 150 is arranged on the fixed plate 110, and the limiting cover 160 is detachably connected to the side of the limiting seat 150 facing away from the fixed plate 110. The limiting seat 150 and the limiting cover 160 are combined to form a limiting hole, and the support arm 320 is rotatably inserted into the limiting hole. The connecting rod 330 and the lighting lamp 310 are respectively connected to the opposite ends of the support arm 320.

[0061] Among them, the limit cover 160 and the limit seat 150 can be connected through a first threaded fastener 180. The first threaded fastener 180 passes through the limit cover 160 and is threadedly connected to the limit seat 150. There can be two first threaded fasteners 180, and the two first threaded fasteners 180 are located on opposite sides of the radial direction of the support arm 320.

[0062] In addition, there can be multiple limit seats 150 and limit covers 160, and the multiple limit seats 150 are arranged at intervals along the axial direction of the support arm 320. The multiple limit covers 160 are connected to the multiple limit seats 150 in a one-to-one correspondence, thereby forming a multi-point connection between the fixing frame 100 and the support arm 320, increasing the relative position reliability between the fixing frame 100 and the support arm 320, and preventing the support arm 320 from deflecting relative to the fixing frame 100.

[0063] By providing a detachable connection between the stopper 150 and the stopper cover 160, the support arm 320 can be easily installed and removed, thereby improving assembly convenience and accommodating a wider range of support arm 320 shapes. Furthermore, the lighting assembly 300 can be removed without removing the fixing frame 100, facilitating maintenance and replacement of the rotating lighting device 1. Furthermore, the provision of the stopper 150 creates a gap between the support arm 320 and the fixing frame 100, thereby reducing the contact area between the support arm 320 and the fixing frame 100, reducing the friction experienced by the support arm 320 during rotation, and improving the smoothness of the rotation of the lighting assembly 300, thereby optimizing the operating performance of the rotating lighting device 1.

[0064] like Figure 2-Figure 4 As shown, in the technical solution of this embodiment, the support arm 320 includes a first shaft arm 321, a connecting block 322 and a second shaft arm 323. Among them, the first shaft arm 321, the connecting block 322 and the second shaft arm 323 can be an integrally formed structure to increase structural strength and improve assembly efficiency.

[0065] The first shaft arm 321 is rotatably inserted into the limiting hole, the connecting rod 330 is connected to one end of the first shaft arm 321, the rotation axis of the support arm 320 coincides with the central axis of the first shaft arm 321, the connecting block 322 is connected to the other end of the first shaft arm 321, the second shaft arm 323 is connected to the side of the connecting block 322 facing away from the first shaft arm 321, the central axis of the second shaft arm 323 is parallel to the first shaft arm 321 and is arranged at intervals, and the lighting lamp 310 is arranged on the second shaft arm 323.

[0066] The diameter of the first shaft arm 321 may be smaller than the diameter of the second shaft arm 323 .

[0067] In this way, the diameter of the first axis arm 321 can be set to be smaller, and the size of the limit seat 150 and the limit cover 160 can be reduced accordingly, thereby reducing the material used in the fixing frame 100, thereby reducing the weight and cost of the fixing frame 100 and reducing the volume of the rotating lighting device 1; the diameter of the second axis arm 323 can be set to be larger, thereby increasing the contact area between the lighting lamp 310 and the support arm 320, and the connection strength between the support arm 320 and the lighting lamp 310 is greater, thereby improving the relative position stability between the support arm 320 and the lighting lamp 310.

[0068] In addition, by arranging the central axis of the first arm 321 and the central axis of the second arm 323 parallel and spaced apart, wherein the lighting direction of the lighting lamp 310 is perpendicular to the central axis of the second arm 323, it is possible to ensure that the lighting direction of the lighting lamp 310 is perpendicular to the rotation axis of the support arm 320, and since the rotation axis of the support arm 320 is the central axis of the first arm 321, the movement stroke of the second arm 323 is larger than that of the first arm 321, which can increase the movement stroke of the lighting lamp 310, control the movement speed of the lighting lamp 310, and improve the lighting effect.

[0069] Furthermore, the lighting fixture 310 includes a mounting rod 311 and a lamp 312. The mounting rod 311 and the lamp 312 can be integrally formed to increase structural strength and improve assembly efficiency. A socket is provided at one end of the mounting rod 311, and a second shaft arm 323 is removably inserted into the socket and mounted on the end of the mounting rod 311 away from the second shaft arm 323.

[0070] Among them, the mounting rod 311 and the second shaft arm 323 can be connected through a second threaded fastener 340. The second threaded fastener 340 passes through the mounting rod 311 and is threadedly connected to the second shaft arm 323. There can be multiple second threaded fasteners 340, and multiple second threaded fasteners 340 are arranged at axial intervals on the mounting rod 311.

[0071] By inserting the second shaft arm 323 into the socket of the mounting rod 311, the contact area between the second shaft arm 323 and the mounting rod 311 can be increased, the connection strength between the second shaft arm 323 and the mounting rod 311 can be improved, and the relative position stability between the second shaft arm 323 and the mounting rod 311 can be ensured.

[0072] In addition, the second shaft arm 323 and the mounting rod 311 are easy to install and disassemble, and the lighting lamp 310 can be disassembled and assembled without changing the connection relationship between the support arm 320, the connecting rod 330, the fixing frame 100 and the driving member 200, which is conducive to replacing and repairing the lighting lamp 310.

[0073] like Figure 1-Figure 2 As shown, in the technical solution of this embodiment, there are multiple lighting assemblies 300, and the multiple lighting assemblies 300 include a first lighting assembly 300 and a second lighting assembly 300. The first lighting assembly 300 and the second lighting assembly 300 are connected to the same driving member 200 and are located on opposite sides of the driving member 200 in the radial direction.

[0074] In this way, the illumination intensity within the illumination range of the rotating lighting device 1 can be increased, which is beneficial to improving the illumination effect of the rotating lighting device 1 .

[0075] According to an embodiment of the present invention, on the other hand, a crane is provided, such as Figure 6 As shown, the crane includes a boom 2 and the above-mentioned rotating lighting device 1, a fixing frame 100 is installed on the boom 2, and a driving member 200 and a supporting arm 320 are arranged on a side of the fixing frame 100 facing away from the boom 2.

[0076] The crane of the embodiment of the present invention can adjust the lighting angle according to needs and ensure good lighting effects through the above-mentioned rotating lighting device 1. It can also be used to observe the telescopic state of the crane arm 2 and illuminate the hoisted objects, which can effectively improve the work adaptability of the crane. It does not require manual adjustment, reduces work risks, and has more flexible angle adjustment. It does not need to set a gear pair structure. It has a simple structure, high reliability, and is not easy to damage. It does not require an additional sealing structure, which can reduce costs.

[0077] like Figure 6 As shown, in the technical solution of this embodiment, the fixing frame 100 is installed on the lower side of the base boom 21 of the boom 2.
