Description

Technical Field

[0001] This utility model relates to the field of industrial lighting technology, and in particular to an auxiliary lighting device for cranes. Background Technology

[0002] Cranes are widely used in ports, construction sites, factory workshops, and mines. Their operation is dynamic and high-risk, creating a rigid demand for lighting. Many operations are carried out at night, in enclosed indoor spaces, underground projects, and in inclement weather, where natural light is severely insufficient, requiring supplemental artificial lighting. During crane operation, the boom extends, contracts, and rotates, and the hook rises, falls, and moves, causing the positions of the load, the connection points of the lifting equipment, and obstacles within the operating radius to constantly change. The lighting needs to accurately follow these dynamic areas. Operators need to visually judge the position, posture, and secure binding of the load, as well as whether there is a risk of collision in the surrounding environment. Therefore, the lighting must have sufficient brightness, clarity, and uniformity to avoid glare and shadow interference.

[0003] Many lifting operations are conducted at night when natural light is completely absent, requiring artificial lighting to clearly see the work area. In factory workshops, warehouses, tunnels, and mines, natural light is difficult to penetrate, necessitating supplemental lighting even during the day. Rain, fog, dust storms, and dense smoke severely weaken light transmission, causing a sharp drop in visibility and creating blind spots even during the day. Safety standards for lifting machinery in various countries clearly require that the work area must have sufficient lighting to ensure that the operator can clearly observe the key parts of the lifting operation. Insufficient lighting is a violation of operating procedures and directly increases the risk of safety accidents. Current technology involves installing floodlights on the top of the cab to illuminate the work radius in front of the operator, facilitating observation of the ground environment. However, mechanical structural jamming can cause the lighting to lag, resulting in temporary blind spots. The operator cannot keep track of the operator's position in real time, increasing the risk of collisions with surrounding equipment and buildings. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary lighting device for cranes, which aims to improve the problem that the existing lighting range still has temporary blind spots, the operator cannot grasp the position in real time, and collisions with surrounding equipment and buildings will directly lead to an increased risk of safety accidents.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a crane auxiliary lighting device, comprising a working surface, a collecting column rotatably connected to the top right side of the working surface, a cable rotatably connected to the outer wall of the collecting column, a sliding box fixedly connected to the outer wall of the cable, through holes on both the left and right sides of the sliding box, a sliding block rotatably connected to the inner wall of the through holes, an umbrella-shaped block fixedly connected to the bottom of the sliding box, a rotating block rotatably connected to the bottom of the umbrella-shaped block, a telescopic shaft fixedly connected to the bottom of the outer wall of the rotating block, and a sliding ring slidably connected to the inner wall of the telescopic shaft. The telescopic shaft two has a fixed disk fixedly connected to its bottom end. A bulb fixing disk is fixedly connected to the center of the bottom surface of the fixed disk. Fixed blocks one are fixedly connected to the front and rear sides of the bottom of the fixed disk. Rotating arms are rotatably connected to the bottom ends of the two fixed blocks one. Rotating bearings are rotatably connected to the bottom ends of the two rotating arms. A spotlight is fixedly connected to the bottom end of the bulb fixing disk. Fixed blocks two are fixedly connected to the left and right sides of the spotlight. Screws are threaded onto the inner wall of the fixed blocks two. A protective mechanism is provided at the bottom end of the umbrella-shaped block. The protective mechanism is used to protect the lighting device.

[0006] As a further description of the above technical solution: The protective mechanism includes a protective shell, the top of which is fixedly connected to the bottom of the umbrella-shaped block. A rotating plate is fixedly connected to the bottom of the protective shell. A rotating groove is formed at the bottom of the rotating plate. A rotating handle is fixedly connected to the right side of the rotating plate. A rotating sealing plate is slidably connected to the inner wall of the rotating groove. A sliding block is fixedly connected to the bottom of the rotating sealing plate. An outer shell is fixedly connected to the bottom of the rotating sealing plate. A rotating groove is formed at the bottom of the outer shell. A cover is rotatably connected to the top of the outer shell. A connecting pin is rotatably connected to the bottom of the outer shell.

[0007] As a further description of the above technical solution: A rotating worktable is rotatably connected to the top left side of the working surface, and telescopic arm fixing blocks are fixedly connected to the front and rear sides of the top of the rotating worktable.

[0008] As a further description of the above technical solution: An operating room is fixedly connected to the top rear side of the rotary worktable, and a lifting arm is rotatably connected between the two adjacent telescopic arm fixing blocks.

[0009] As a further description of the above technical solution: Roller fixing strips are fixedly connected to the front and rear sides of the top of the lifting boom, and a rotating wheel is rotatably connected between adjacent roller fixing strips.

[0010] As a further description of the above technical solution: Stabilizing frames are fixedly connected to the four corners at the bottom of the working surface, and foot pads are fixedly connected to the bottom of the stabilizing frames.

[0011] As a further description of the above technical solution: The outer wall of the cable is rotatably connected to a hook fixing frame, and the inner wall of the hook fixing frame is rotatably connected to a lifting hook.

[0012] As a further description of the above technical solution: The right side of the working surface is fixedly connected to the cab, and tires are rotatably connected to the front and rear sides of the bottom of the working surface.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the cable drives the sliding box and the umbrella-shaped block to move up and down. The rotating block can rotate at any angle in the umbrella-shaped block to achieve the up and down adjustment of the angle. The first telescopic shaft drives the second telescopic shaft to retract in the fixed disc, which in turn drives the bulb fixing disc and the spotlight to retract, thereby adjusting the size of the light. When in use, the size and angle of the light can be adjusted at will, avoiding the problems of insufficient light in the dark and unsafe construction.

[0014] 2. In this utility model, when the spotlight retracts inward, turning the handle to the left causes the rotating plate to rotate to the left, and the rotating sealing plate slides in the rotating plate, so that the sliding block slides in the rotating groove two, thereby protecting the spotlight. Turning the handle to the right causes the rotating plate to rotate to the right, and the rotating sealing plate and the sliding block slide in the same way, so that the spotlight can be used. When the spotlight is not in use, it can avoid being exposed to the outside world and damaged, thus extending its service life and saving costs. Attached Figure Description

Turning the handle 209 to the right causes the rotating plate 202 to rotate to the right, which in turn causes the sealing plate 203 to slide in the rotating plate 202, and the sliding block 204 to slide in the rotating groove 206, thus enabling the spotlight 15 to be used. When the spotlight 15 is not in use, it is protected to prevent the spotlight 15 from being exposed to the outside and damaged.
