[0002] Lifting machinery refers to mechanical equipment used for vertically lifting or horizontally moving heavy objects, and is widely used in construction, manufacturing, logistics, ports, and other fields. Its core function is to perform operations such as lifting, loading, unloading, and installation of heavy objects through mechanical or electric means.
[0003] However, when existing lifting machinery is used outdoors in strong sunlight, the strong light shining on the gear position display of the lifting machinery will cause glare. Although the existing gear position display is equipped with a light shield, the light shield needs to be driven by an additional cylinder or motor to further improve the light shielding effect of the gear position display. The additional cylinder or motor requires the lifting equipment to provide power, which will cause additional power loss to the lifting equipment and is not environmentally friendly. This phenomenon has become a problem that urgently needs to be solved by people in this field. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a display device for the operating gear of a lifting machinery, including a crane body 1 and a gear display 2. The gear display 2 is installed inside the crane body 1. A mounting frame 3 is fixedly connected to the outside of the gear display 2. A light-shielding frame 4 is detachably connected to the outside of the mounting frame 3. A light-shielding component is provided on the light-shielding frame 4, including an upper light-shielding plate 8 and a side light-shielding plate 10.

[0021] It should be noted that the single-crystal silicon thin film 9 is made by screen printing or sputtering, which is a mature existing technology and will not be elaborated on in this application.
[0022] It should be added that the inverter 16 converts DC power into AC power through semiconductor switching circuits (such as IGBTs and MOSFETs) and stores it in the battery 15 for use by electronic components. This is a mature prior art and will not be elaborated on in this application.
[0023] refer to Figure 1 and Figure 2The gear position display 2 is fixedly installed inside the cab of the crane body 1 via the horizontal plate at its bottom. The inner wall of the mounting frame 3 is fixedly connected to the outside of the gear position display 2. Connecting grooves (not shown in the figure) are provided on both sides of the mounting frame 3. Connecting strips (not shown in the figure) are provided on the two inner side walls of the light shield 4. The specifications of the connecting grooves and connecting strips are compatible, which makes it easier to disassemble the light shield 4 and the mounting frame 3.
[0024] The upper sunshade 8 is slidably set on the upper part of the sunshade frame 4 to block the sunlight above the cab and prevent the gear position display 2 from reflecting light. The side sunshade 10 is provided in two sets and is slidably set on both sides of the sunshade frame 4 to block the sunlight on both sides of the cab and prevent the gear position display 2 from reflecting light on both sides.
[0025] Both the upper light-shielding plate 8 and the side light-shielding plate 10 have a monocrystalline silicon thin film 9 laid on their light-facing surfaces. The monocrystalline silicon thin film 9 is electrically connected to the inverter 16, and the inverter 16 is electrically connected to the battery 15. When the upper light-shielding plate 8 and the side light-shielding plate 10 extend outward from the inside of the light-shielding frame 4 to perform the light-shielding function, the monocrystalline silicon thin film 9 on their light-facing surfaces can convert the collected light energy into electrical energy through the inverter 16 and store it in the battery 15 to power the various electrical components in the light-shielding frame 4.
[0026] A through groove is provided in the upper cavity 11, and the upper light shield 8 is slidably connected inside the through groove. The upper and lower surfaces of the upper light shield 8 are in sliding contact with the inner top and inner bottom surfaces of the through groove in the upper cavity 11.

Another through groove adapted to the specifications of the side light shield 10 is provided in each of the two side cavities 17. The left and right surfaces of the side light shield 10 are in sliding contact with the inner left and inner right surfaces of the side through groove, respectively.
[0027] A cylinder 12 is fixedly connected in the upper cavity 11. The fixed end of the cylinder 12 is fixedly connected to the inner wall of the upper cavity 11. The output end of the cylinder 12 is fixedly connected to the upper light shield 8. The cylinder 12 is electrically connected to the controller 5 and the battery 15.
[0028] refer to Figure 2 and Figure 3 The cylinder 12 can drive the upper light shield 8 to move in the front and back direction by extending and retracting its output end, thereby blocking sunlight and preventing the position display 2 from reflecting light.
[0029] A mounting plate 18 is fixedly connected to the inner wall of the side cavity 17. A rotating rod 21 is rotatably connected to the upper surface of the mounting plate 18 via a bearing. The rotating rod 21 is perpendicular to the mounting plate 18. The top of the rotating rod 21 passes through the light-shielding frame 4 and is fixedly connected to a motor 6. A gear 20 is fixedly connected to the rotating rod 21. The gear 20 meshes with a rack 19. The rack 19 is fixedly connected to the side light-shielding plate 10.
[0030] refer to Figure 3 and Figure 5 The motor 6 drives the rotating rod 21 to rotate through the rotation of its output shaft. The rotating rod 21 indirectly drives the gear 20 to rotate. The gear 20 drives the rack 19 to move in the front-back direction of the light shield 4 through meshing, thereby driving the side light shield 10 on that side to move in the front-back direction of the light shield 4, so as to avoid the reflection phenomenon on both sides of the position display 2 due to strong light.
[0031] The light-shielding frame 4 has a sliding groove 42, which is slidably connected to the rack 19. A limiting groove 41 is provided at the bottom of the sliding groove 42, and a limiting strip 191 is fixedly connected to the bottom of the rack 19. The limiting strip 191 is slidably connected to the limiting groove 41.
[0032] refer to Figure 4 and Figure 5 The slide groove 42 is used to guide the rack 19 to move in the front and back direction. The limiting strip 191 and the limiting groove 41 are slidably connected to prevent the rack 19 from jamming when it moves in the front and back direction.
[0033] A connecting rod 13 is fixedly connected between the outer walls of the two side cavities 17. A cooling fan 14 is fixedly installed on the connecting rod 13. The cooling fan 14 is electrically connected to the battery 15. The air outlet of the cooling fan 14 faces the back of the gear position display 2. Heat dissipation holes 7 are provided on both side cavities 17. The heat dissipation holes 7 can circulate the air generated by the cooling fan 14 while dissipating heat, thereby indirectly improving the heat dissipation effect of the cooling fan 14 on the back of the gear position display 2.
[0034] refer to Figure 2 , Figure 4 and Figure 5 The battery 15 provides power to the cooling fan 14 through wires. The battery 15 transmits the electrical energy converted by the inverter 16 to the cooling fan 14. The operation of the cooling fan 14 can blow air to cool the back of the gear position display 2, which can effectively prevent the gear position display 2 from overheating. At the same time, by using the monocrystalline silicon thin film 9, the collected light energy can be converted into electrical energy through the inverter 16 to power the cylinder 12, motor 6 and controller 5. While providing a light shielding effect for the gear position display 2, it can also further reduce energy consumption and make it more environmentally friendly.
