[0022] Example 1

[0023] Please see Figure 1 The safety zone warning device provided by this utility model includes a fixing component 1, a spotlight component 4, an adjusting component 3, and a housing 2. The fixing component 1 is assembled on the housing 2, and the spotlight component 4 is assembled inside the housing 2 through the adjusting component 3, for projecting a warning light ring in the warning area.

[0024] It is known that when safety warnings are required in an area, the device is fixed to the crane vehicle via the fixing component 1, i.e., above the warning area. The length of the light lines projected by each spotlight component 4 can be adjusted first. After adjustment, the length of each light line changes, and the light lines emitted by the spotlight component 4 at the original angle and position can no longer form a closed warning light circle. Therefore, the angle of the spotlight component 4 can be adjusted by the adjusting component 3 to form a closed warning light circle, thus adapting well to warning areas of different sizes. The size requirement of the warning area is mainly to adapt to the different sizes of hoisted items.

[0025] Please see Figure 1 In some embodiments, the spotlight component 4 includes at least four spotlights, all of which are mounted on the adjustment component 3 to project a rectangular warning light ring.

[0026] Understandably, the four spotlights can be positioned at the four corners of a rectangle. These spotlights can be laser spotlights, each emitting a straight line of light. The four laser spotlights project a rectangular warning circle over the warning area. Each spotlight can include a laser emitter, two sets of reflectors, and a Powell prism. The light emitted from the laser emitter is reflected by the two sets of reflectors to the right side of the Powell prism, and then emitted from the left side of the Powell prism in a radial pattern, i.e., a straight line. The length of the straight line of light can be adjusted by placing the laser emitter, the two sets of reflectors, and the Powell prism at... The first cylinder has an external thread, and the second cylinder has a tapered cavity that is larger on the left and smaller on the right. The inner wall of the tapered cavity has an internal thread. The second cylinder is connected to the external thread of the first cylinder through the internal thread. By adjusting the threaded connection position between the second and first cylinders, the relative positions of the first and second cylinders in the left and right directions can be changed. This allows for adjustment of the distance between the Powell prism and the left side wall of the second cylinder, thereby adjusting the length of the linear light line. By adjusting the relative angle between the laser spotlights, a closed warning light circle can be formed between the linear light lines.

[0027] Please continue reading. Figure 1 In some embodiments, the adjusting component 3 includes an electric telescopic rod and a connector. The electric telescopic rod is mounted on the outer shell 2 and is connected to the spotlight component 4 through the connector. The spotlight component 4 is rotatably connected to the outer shell 2 through a fulcrum.

[0028] Understandably, the spotlight can be rotatably connected to the inner wall of the outer casing via a fulcrum. The fulcrum can be a structure similar to a pin, and the connecting part can be a collar. The collar is fitted onto the spotlight and welded to the electric telescopic rod. The extension and retraction of the electric telescopic rod drives one end of the spotlight component 4 to move, thereby adjusting the angle of the spotlight to adjust the position of the linear light line.

[0029] Please see Figure 1 In some embodiments, the fixing member 1 includes a connecting seat 101 and a fixing seat 102, and the fixing seat 102 is connected to the outer shell 2 through the connecting seat 101.

[0030] It is understood that the mounting base 102 can be used to mount on a crane above the warning area. The mounting base 102 and the connecting base 101 can be an integral structure. The connecting base 101 can be inverted U-shaped. The connecting base 101 can be welded to the outer shell 2 or bolted to it. The mounting base 102 can be fixed to the crane by bolts or other means. This fixing component 1 can facilitate the connection between the spotlight component 4 and the crane.

[0031] Please see Figure 1In some embodiments, the fixing base 102 includes a fixing plate and a connecting rod, and the connecting rod is connected to the connecting base 101 through the fixing plate.

[0032] Understandably, the fixing plate can be welded to the connecting seat 101, and there can be two connecting rods. The connecting rods can be bent to clamp onto the support of the crane.

[0033] Please see Figure 1 In some embodiments, the connecting rod includes a connecting section and a bent section, the connecting section being connected to a fixed plate, and the bent section being perpendicularly connected to both ends of the connecting section.

[0034] Understandably, the bending section can be bent to form a wraparound space, which can then be tightly secured to some supports of the crane trolley. This fixing method is simple and quick.

[0035] Please see Figure 1 In some embodiments, the warning device also includes a power supply 5, which is electrically connected to the spotlight component 4 and the adjustment component 3, and is used to supply power to the spotlight component 4 and the adjustment component 3.

[0036] Understandably, by setting up power supply 5, there is no need to connect an external power source, thus improving the overall ease of use.

[0037] Please see Figure 1 In some embodiments, the warning device further includes a wireless controller 6, which is electrically connected to the spotlight component 4 and the adjustment component 3 for remotely controlling the spotlight component 4 and the adjustment component 3.

[0038] Understandably, the wireless controller 6 can remotely receive control commands to control the opening and closing of the spotlight component 4, and can also control the movement of the electric telescopic pole. A fan 7 can be installed inside the housing 2 for heat dissipation of the components inside the housing 2.

[0039] Example 2

[0040] This embodiment provides a crane vehicle, including the safety zone warning device described above.

[0041] Understandably, the warning device can be fixed to the crane's support frame using a fixing component.

[0042] As described above, the safety zone warning device provided by this utility model can adjust the size of the formed warning light circle according to actual needs, thereby adapting to different hoisted items, improving the safety of the hoisting process, and avoiding the occurrence of safety accidents.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
