Description

Technical Field

[0001] The utility model relates to a multifunctional overhead crane warning projection lamp, belonging to the technical field of overhead crane warning projection lamps. Background Art

[0002] Overhead crane is a device used to carry out the lifting of large parts or articles in the factory. The warning light on the overhead crane is used as the warning part of the overhead crane. When the overhead crane is working, it will generate sound and light warnings to serve the purpose of safety warning. In the production and operation process of the multifunctional overhead crane in the electrolysis workshop, there are safety hazards of falling objects from high altitude and injuring people. In production, there have been actual accidents of falling bolts, small box fixtures, grabs, and feeding pipes. Since the routine operations such as sitting and pulling poles during pole changing operations, aluminum tapping, and lifting busbars require operators to be as close as possible to the projection area of ​​the multifunctional overhead crane tool cart, once falling objects from high altitude occur, it will greatly endanger the personal safety of ground operators.

[0003] For example, a warning light for an overhead crane with patent publication number CN202222029680.2 includes a lamp holder, a lampshade is arranged on the top of the lamp holder, an end frame is fixed to the bottom side wall of the lamp holder, a rotating block is arranged on the inner side of the end frame, an adjusting block is sleeved on the outer wall of one end of the rotating block, a threaded hole is opened on the side wall of the adjusting block, a threaded rod is connected to the inside of the threaded hole through a thread, and a rotating column is connected to one end of the threaded rod;

[0004] Since the above-mentioned overhead crane warning light is installed in a vertical position, and the operation of the overhead crane warning light warns ground operators and other pedestrians that it is not necessary to enter the warning area or stay there for a long time, it greatly endangers the personal safety of ground operators. However, the warning effect is limited only by light, and it is inconvenient to warn people who move backwards, which brings certain adverse effects to actual use and therefore needs to be improved.

[0024] Example 1 Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A multifunctional overhead crane warning projection lamp comprises a placement frame 1 with a mounting plate, a driving motor 2 is fixedly installed on the left side of the inner wall of the placement frame 1 through a bracket, a rotating rod 3 is fixedly connected to the output end of the driving motor 2, a connecting plate 4 is fixedly connected to the surface of the rotating rod 3, a mounting seat 5 is fixedly installed on the front side of the connecting plate 4, a positioning plug plate 6 is fixedly connected to the front side of the mounting seat 5 near the top and bottom thereof, a warning projection lamp body 7 is clamped on the surface of the positioning plug plate 6, a firm threaded groove 8 is opened on the front side of the mounting seat 5 near the left and right sides thereof, a firm screw 9 is threadedly connected to the inner wall of the firm threaded groove 8, and the surface of the firm screw 9 is threadedly connected to the warning projection lamp body 7, a warning ring 10 is fixedly connected to the surface of the warning projection lamp body 7, and a human infrared sensor lamp 11 with an alarm is fixedly installed on the front side of the warning ring 10.

[0026] Specifically, Figure 1-Figure 4 As shown, a liquid level 12 is fixedly connected to the top of the placement frame 1, and the liquid level 12 is located at the rear center of the placement frame 1. The liquid level 12 added at the top of the placement frame 1 can be used to observe the horizontal placement effect of the warning projection lamp body 7.

[0027] Specifically, Figure 1-Figure 4 As shown, a vertical pole 13 is fixedly connected to the top of the inner wall of the placement frame 1, and an annular sleeve 14 is fixedly connected to the bottom of the vertical pole 13. The inner wall of the annular sleeve 14 is rotatably connected to the surface of the rotating rod 3. Under the sliding constraint of the annular sleeve 14 below the vertical pole 13, the horizontal straightness of the rotation of the rotating rod 3 can be guaranteed.

[0028] Furthermore, a magnetic plate 15 is fixedly connected to the front side of the mounting seat 5 near the middle thereof, and the surface of the magnetic plate 15 is magnetically engaged with the rear side of the warning projection lamp body 7, and the magnetic plate 15 at the middle position can be adsorbed and fixed to the warning projection lamp body 7 for a second time. A shielding plate 18 is rotatably connected to the front side of the placement frame 1 through a hinge, and a positioning magnetic plate 1 19 is fixedly connected to the front side of the shielding plate 18, and a positioning magnetic plate 2 20 is fixedly connected to the top of the placement frame 1, and the surface of the positioning magnetic plate 2 20 is magnetically abutted against the surface of the positioning magnetic plate 1 19, and the shielding plate 18 is pulled to abut against the front side of the placement frame 1 by using the magnetic positioning effect of the positioning magnetic plate 1 19 and the positioning magnetic plate 2 20, thereby achieving the effect of leaking the warning projection lamp body 7 from the inside of the placement frame 1.

[0029] Example 2 Please refer to Figure 1-Figure 4 The difference between this embodiment and embodiment 1 is that a shock absorber 16 is fixedly connected to the bottom of the placement frame 1, and an arc-shaped receiving frame 17 is fixedly connected to the bottom end of the shock absorber 16. Through the setting of the shock absorber 16, the shock absorption reduces the impact force on the receiving frame caused by the falling of the warning projection lamp body 7.

[0030] Working principle of the utility model: when in use, the staff can use the mounting plate at the rear side of the placement frame 1 to install it on the overhead crane, that is, it can be installed by rotating the screw for threaded positioning. In the actual use of the placement frame 1, it is necessary to lift the shield plate 18 used for protection in the normal state, and use the magnetic positioning effect of the positioning magnetic plate 19 and the positioning magnetic plate 20 to pull the shield plate 18 to abut against the front side of the placement frame 1, thereby achieving the effect of leaking the warning projection lamp body 7 inside the placement frame 1. According to the warning words and warning range set by the staff, the warning projection lamp bodies 7 of different specifications are replaced and installed, and the positioning plug plate 6 and the corresponding clamping position of the warning projection lamp body 7 are used for rapid positioning, and the magnetic plate 15 at the middle position can be adsorbed and fixed for a second time. After the basic positioning of the warning projection lamp body 7 is completed, it can be firmly fixed. The screw rod 9 rotates to enter the fixed thread groove 8 for thread positioning, and the driving motor 2 drives the rotating rod 3 to rotate. Under the sliding constraint of the annular sleeve 14 under the vertical pole 13, the horizontal straightness of the rotation of the rotating rod 3 can be guaranteed. Because a warning circle 10 is added to the outer ring of the warning projection lamp body 7, and multiple human infrared sensor lamps 11 are added to the warning circle 10, personnel can be warned not to approach the dangerous area. Because an arc-shaped receiving frame 17 is provided at the bottom of the placement frame 1, it can receive the warning projection lamp body 7 in case of accidental drop. Through the setting of the shock absorber 16, the shock absorption reduces the impact of the warning projection lamp body 7 falling on the receiving frame. A liquid level 12 is added to the top of the placement frame 1 for observing the horizontal placement effect of the warning projection lamp body 7, thereby ensuring the safety protection of the warning projection lamp and the practicality of angle adjustment and easy disassembly.
