[0002] Excavators are a very important type of equipment in construction machinery. They are widely used in construction, transportation, military and other engineering operations. With the development of infrastructure and the development of industries such as real estate, the demand for excavators has further increased, and nighttime construction has also increased. The headlights installed on the boom of the excavator are an indispensable part of its lighting system. The headlights on the boom are generally installed on the boom through a fixed bracket, and the installation angle and lighting range are set.

[0003] The existing boom headlight fixing bracket is mostly fastened to the fixing base welded on the boom with a bolt. With the increase of the operating time of the working device, especially when the working device is mounted with a breaker hammer, the bolt is easy to loosen, causing the illumination angle of the boom light connected to the fixing bracket to shift, which affects the illumination range of the boom light to a certain extent, and then affects the operator's operating line of sight, reducing the work efficiency at night and also posing an operational safety risk.

[0027] Embodiment 1

[0028] In order to enhance the stability of the boom headlight after installation and improve the connection strength between the boom and the excavator, the present application adds a new fixing point on the basis of the traditional headlight fixing bracket fixed to the boom by a bolt, which effectively prevents the problem of loosening of the fixing bolt as the operating time of the working device increases, and at the same time supports multi-angle adjustment of the light bracket.

[0029] In a typical embodiment of the present application, an angle-adjustable mounting device for an excavator boom headlight is provided, such as Figure 1-2 As shown, it includes a mounting base 1 welded to the boom and a boom lamp bracket 2 connected to the mounting base, the mounting base 1 is provided with a fixed mounting hole 11 and a plurality of angle adjustment holes 12 distributed in a ring around the fixed mounting hole; the boom lamp bracket 2 is provided with a first bolt through hole 21 corresponding to the fixed mounting hole and a second bolt through hole 22 corresponding to the angle adjustment hole; the mounting base 1 is bolted to the boom lamp bracket 2.

[0030] Specifically, the boom light bracket is used to install the boom headlight, and the boom light bracket is fixedly connected to the mounting base by bolts, and the mounting base is welded to the excavator boom. Figure 1 As shown, in order to improve the connection strength with the boom, a fixed installation hole 11 and multiple angle adjustment holes 12 are set on the mounting base 1, and the first bolt through hole 21 and the second bolt through hole 22 are correspondingly opened on the boom lamp bracket 2, wherein the fixed installation hole 11 and the angle adjustment hole 12 are both threaded holes, and the first bolt through hole 21 and the second bolt through hole 22 are both light holes. The first fixing bolt 3 passes through the first fixing bolt through hole 21 and the fixed installation hole 11 in turn to connect and fix the boom lamp bracket with the mounting base, and the second fixing bolt 5 passes through the second fixing bolt through hole 22 and one of the angle adjustment holes 12 in turn to connect and fix the boom lamp bracket with the mounting base, thereby realizing the dual-point fixed installation of the boom headlight. Considering the light weight of the boom headlight, dual-point fixation is sufficient. Of course, when installing a heavier boom lamp, a third fixing point can also be set.

[0031] To ensure a stable connection between the mounting base and the boom lamp, a first gasket 4 is provided between the first fixing bolt 3 and the first bolt through hole 21, and a second gasket 6 is provided between the second fixing bolt 5 and the second bolt through hole 22, which can prevent the bolts from loosening and improve the sealing and stability of the connection.

[0032] Among them, the thread diameter of the second fixing bolt is smaller than the thread diameter of the first fixing bolt, that is, correspondingly, on the mounting seat, the diameter of the angle adjustment hole 12 is smaller than the diameter of the fixed mounting hole 11; on the boom bracket, the diameter of the second bolt through hole 22 is smaller than the diameter of the first bolt through hole 21, which can reduce the installation space under the condition of ensuring the connection strength. In the installation of the boom lamp bracket, the first fixing bolt plays a main fixing role, and the second fixing bolt plays an auxiliary fixing role. At the same time, through the number and angle setting of the angle adjustment holes, the second fixing bolt can be replaced with different installation positions, thereby adjusting the installation angle and illumination range of the boom headlight, which can meet the needs of night operations under different working conditions.

[0033] like Figure 2 As shown, the number of angle adjustment holes can be selected and arranged according to actual usage requirements. Multiple angle adjustment holes 12 are arranged on a circle with the center of the fixed installation hole as the center and the center distance between the first bolt hole and the second bolt hole as the radius, so as to achieve the purpose of adjusting the installation angle of the boom lamp bracket, and then realize the adjustment of the illumination angle of the boom headlight, adapt to various working conditions for lighting, and improve the safety of night operation.

[0034] The boom lamp bracket 2 is a folded plate structure, and a connection hole 23 for fixing the boom lamp is provided on the boom lamp bracket, and the connection hole 23 and the first bolt through hole 21 are located in different planes. The corners and edges of the boom lamp bracket are rounded to reduce stress concentration and reduce the weight of the bracket.

[0035] In addition, the mounting seat 1 is set to a cylindrical structure, which can reduce the installation space. The inner and outer diameters of the second gasket are smaller than the inner and outer diameters of the first gasket, and the outer diameter of the mounting seat can be reduced as much as possible under the condition of ensuring the installation space.

[0036] To ensure the durability of the installation device, the mounting base and the boom lamp bracket need to meet certain strength requirements and anti-corrosion performance. Therefore, the mounting base and the boom lamp bracket are usually made of steel. In this embodiment, the mounting base and the boom lamp bracket are made of Q355B steel to meet the strength and durability requirements.

[0037] In another embodiment, the present application further provides an excavator, including a boom headlight, which uses the above-mentioned angle-adjustable mounting device to install the boom headlight on the excavator.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Those skilled in the art should understand that the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
