[0027] refer to Figure 1 , Figure 1 A front overall perspective view of an embodiment of the electric box bracket of the present application is shown. The first support frame is fixedly connected to the electric box 8. In one embodiment, the first support frame includes an upper first support frame 11 and a lower first support frame 12. In one embodiment of the electric box bracket of the present application, on one hand, the electric box 8 is fixedly connected to the electric box fixing plate 3 by bolts, for example, in addition or alternatively, the electric box 8 and the electric box fixing plate 3 can also be formed into an integral form, and the structure of the electric box fixing plate 3 is Figure 5 As best shown in FIG, on the other hand, the upper first support frame 11 and the lower first support frame 12 are fixedly connected to the electric box fixing plate 3 by bolts, for example, so that the connection between the electric box 8 and the first support frame can be more stable.

[0028] In one embodiment, a plurality of vibration damping devices 6 are fixedly connected to the upper first support frame 11 and the lower first support frame 12, for example, by bolts. The vibration damping devices 6 are, for example, vibration damping pads, which can be made of elastic materials such as rubber. In a specific embodiment, four vibration damping devices 6 are placed to abut against the electrical box fixing plate 3, thereby effectively achieving a vibration damping effect. In one embodiment of the electrical box bracket of the present application, a reinforcing rib 7 is provided between the upper first support frame 11 and the lower first support frame 12, thereby increasing the rigidity and strength of the entire electrical box bracket. It should be noted that the reinforcing rib 7 can be formed integrally with the upper first support frame 11 and the lower first support frame 12, thereby reducing the number of components. Reducing the number of accessories can improve product quality and production efficiency. Since the coordination and assembly between parts are reduced, the hidden danger of the component failing to work due to failure of fasteners or a certain part can be reduced. At the same time, the overall weight of the component is reduced, the working state can reach the optimal state, and the stability and reliability of the product are improved.

[0029] In one embodiment, the second support frame 2 is fixed on the plate 10 of the open-pit drilling rig, for example, by bolts. Figure 3As shown in , in addition or alternatively, the second support frame 2 can be formed integrally with the plate 10 of the open-pit drilling rig. The second support frame 2 is configured to have a through hole adapted to the rotating component 4, and the rotating component 4 can be inserted through the through hole via a gasket, for example. Figure 4 As shown in FIG, the top of the rotating component 4 is configured in a hexagonal nut pattern, facilitating installation and removal. The other end of the rotating component 4 has threads for connecting to a fixing nut. In one embodiment, the top of the rotating component 4 has mounting threads for a lubricant addition device, specifically a grease nipple. In one embodiment, a lubricant addition device 5, such as a grease nipple, can be mounted on the grease nipple mounting threads, thereby allowing lubrication to be added to the rotating component 4, making rotation easier.

[0030] Reference again Figure 1 In one embodiment, the upper first support frame 11 and the lower first support frame 12 are connected to the rotating component 4, so that the upper first support frame 11 and the lower first support frame 12 can rotate relative to the second support frame 2. In another embodiment, the rotating component 4 includes a first rotating component 41 and a second rotating component 42, and the upper first support frame 11 and the lower first support frame 12 are connected to the first rotating component 41 and the second rotating component 42, respectively. In this way, the lubricating oil can be lubricated more effectively and the manufacturing cost of the rotating components can be reduced.

[0031] According to one embodiment of the electrical box support of the present application, the support further includes a movable support leg, specifically, a caster bracket 21 and a caster 22. The caster bracket 21 is fixedly connected to the first support frame, specifically, the lower first support frame 12, for example, by bolts. The caster 22 is fixedly connected to the caster bracket 21, for example, by bolts. The caster 22 contacts the surface drilling rig's platform 10, thereby providing vertical support for the entire electrical box support. Without the caster 22, the electrical box is eccentric relative to the rotating component. Under the influence of the weight of the electrical box for a long time, the rotating component 4 will bend and deform. With the caster 22, the entire electrical box support is more evenly stressed, thereby increasing the service life of the rotating component 4. It should be noted that the caster bracket 21 can also be integrally formed with the lower first support frame 12. In one embodiment, the surface of the caster 22 is made of a material such as polyamide, thereby protecting the paint on the surface drilling rig's platform 10, which contacts the caster 22, while also making the electrical box easier to rotate.

[0032] According to one embodiment of the electric box bracket of the present application, the electric box bracket further includes a caster fixing device 13, such as Figure 2As best seen, when the electrical box 8 does not need to be rotated, one end of the caster fixing device 13 is connected to the surface drilling rig's platform 10, for example, by bolts, and the other end is connected to the caster bracket 21, for example, by bolts, thereby fixing the electrical box bracket and preventing it from rotating, thereby preventing it from moving arbitrarily under external forces. In other embodiments, the caster bracket 21 can be fixed relative to the platform 10 by various other means, such as bonding, meshing, etc.

[0033] The present application also discloses an open-pit drilling rig comprising the above-mentioned electrical box bracket.

[0034] The beneficial effects of the various parts of the electric box bracket according to the present application are as follows: the vibration-damping pad provides a vibration-damping effect to the electric box; the casters make the overall force of the bracket balanced and make the movement and operation of the electric box more convenient; the addition of reinforcing ribs between the upper and lower support frames can increase the stiffness and strength of the entire electric box bracket; the addition of rotating parts between the horizontal support frame and the vertical support frame solves the problems of inconvenient maintenance of the electric box and blocking other maintenance points; the special material on the caster can prevent scratches on the paint surface of the flat plate in contact with the caster; the caster and the flat plate of the open-pit drilling rig are connected by a caster fixing device, so that the electric box can be fixed and immovable when the electric box is not rotated.

[0035] The above is a schematic description of the present application and its embodiments, which is not restrictive. The drawings show only one embodiment of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present application, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present application.
