TECHNICAL FIELD

[0001] The utility model belongs to the field of engineering machinery safety protection technology, specifically relates to an engineering machinery LED lamp protection device. BACKGROUND

[0002] With the continuous development of engineering machinery technology and the continuous expansion of application field, the excavator as important construction equipment plays an irreplaceable role in the complex environment such as open pit mine, construction site etc. However, in these harsh working environments, the lighting lamp installed on the top of the excavator often becomes the key component vulnerable to damage. Since the excavator usually needs to work at night or in insufficient light, the stability and reliability of the lighting lamp are directly related to the working efficiency and safety of the engineering machinery.

[0003] In the existing technology, the protection measures for the lighting lamp on the top of the excavator mainly have the following problems: first, the protection effect is poor, and the traditional protection device mostly adopts a simple shielding structure, such as a metal cover or a plastic shell etc. These structures can block the direct impact of external objects to a certain extent, but cannot effectively prevent the splashing of gravel. At the same time, these protection devices are prone to deformation or breakage when subjected to a large impact force, and cannot effectively protect the lighting lamp. Second, the installation is inconvenient, and part of the protection device needs to be replaced after being damaged, which not only increases the maintenance cost, but also prolongs the downtime and affects the normal use of the engineering machinery. SUMMARY

[0004] In view of the above problems, the utility model aims to provide an engineering machinery LED lamp protection device, which solves the problems of inconvenient installation, the need for overall replacement after damage, poor protection effect, and easy breakage due to lack of buffering effect when subjected to the impact of gravel in the existing engineering machinery LED lamp protection devices on the market.

[0008] As a further improvement of the above technical solution: the end face of the vertical plate away from the horizontal plate is provided with a reinforcing rib plate, and the reinforcing rib plate is a triangular plate structure.

[0009] The improved beneficial effect is: the reinforcing rib plate can improve the structural strength of the vertical plate, thereby improving the protection performance of the protection device as a whole when impacted.

[0010] In order to avoid the oil pressure buffer body from being splashed by the gravel;

[0011] As a further improvement of the above technical solution: the top end of the vertical plate is connected with a protection plate, the width of the protection plate is not less than the diameter of the oil pressure buffer, and the length of the protection plate is not less than the length of the oil pressure buffer.

[0012] The improved beneficial effect is: the protection plate cooperates with the upper pressing plate arranged in front of the oil pressure buffer to protect the oil pressure buffer, avoiding the damage of the oil pressure buffer body by the splashing gravel of the excavator and the falling gravel from above.

[0013] In order to make the oil pressure buffer play an effective buffering energy absorption role;

[0014] As a further improvement of the above technical solution: the upper pressing plate is an angle iron structure, the sliding groove is a strip-shaped groove structure, and the extension direction of the sliding groove is the axial direction of the oil pressure buffer.

[0015] The improved beneficial effect is: the transparent protection plate can drive the upper pressing plate to move synchronously after being impacted, and extrude the oil pressure buffer under the limitation of the sliding groove, absorbing the impact potential energy of the gravel.

[0017] As a further improvement of the above technical solution: the transparent protection plate is an angle iron structure, and the width of the transparent protection plate is not less than the width of the top illuminating lamp.

[0018] The improved beneficial effect is: the transparent protection plate can effectively protect the top illuminating lamp in two directions, avoiding the damage of the top illuminating lamp by the splashing gravel and the falling gravel.

[0019] In order to effectively ensure the installation stability of the transparent protection plate and the upper pressing plate;
