Abstract
Description
Technical Field
[0001] This utility model relates to the field of muck loader protection technology, and in particular to a muck loader chassis protection device. Background Technology
[0002] A muck loader is a specialized piece of machinery used in mines, tunnels, underground engineering, and other similar settings. It is mainly used for cleaning, loading, and transporting materials such as gravel and slag. The core function of a muck loader is to use a bucket to scoop loose materials into a conveying device, which is usually a belt conveyor, thereby achieving efficient muck removal operations. Muck loaders typically use a tracked chassis to ensure strong terrain adaptability.
[0003] Tracked chassis are very flexible in their movement, but the gears and rollers of the tracked chassis are exposed. These components come into direct contact with ground debris and sharp objects, causing them to wear down quickly and increasing costs. Furthermore, debris and sharp objects can get stuck in the gears and rollers, damaging the chassis.
[0004] Therefore, how to provide a protective device for the chassis of a muck loader is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] One objective of this invention is to provide a protective device for the chassis of a muck loader. This invention solves the problem in the prior art that the exposed chassis components such as gears and rollers inside the tracked chassis of a muck loader are in direct contact with gravel and sharp objects, which accelerates the wear of the chassis components and causes them to get stuck on the gears and rollers, resulting in chassis damage.
[0006] A protective device for a muck loader chassis according to an embodiment of the present invention includes a chassis frame, a track body disposed on the side of the chassis frame, and a protective component disposed on the side of the chassis frame; the protective component includes a protective cover and an installation component, the installation component is disposed on the side of the chassis frame, the protective cover is installed on the side of the chassis frame through the installation component, and the side of the protective cover is movably fitted against the inner wall of the track body.
[0007] The protective cover has a flexible rubber ring on its side, which is attached to the inner wall of the track body.
[0008] A guide shovel is provided on the side of the protective cover near the bottom.
[0009] The mounting assembly includes a mounting base, positioning blocks, fixing screws, and fixing nuts. The mounting base is located on the side of the chassis frame. There are two sets of positioning blocks, which are symmetrically arranged on the surface of the mounting base with the vertical axis of symmetry of the mounting base as the axis of symmetry. The fixing screws are fixedly connected to the axis of symmetry of the mounting base. The protective cover is movably fitted onto the surface of the positioning blocks. One side of the mounting base is attached to the inner side of the protective cover. The fixing nuts are threaded onto the surface of the fixing screws and are attached to the side of the protective cover.
[0010] The number of fixing nuts is two sets, and both sets of fixing nuts are threaded onto the surface of the fixing screw.
[0011] The protective assembly also includes a gear protection kit, which includes a gear protective cover and an anti-sway component. The gear protective cover is rotatably connected to one end face of the protective cover body via a hinge, and the anti-sway component is disposed on the surface of the gear protective cover and the protective cover body.
[0012] The anti-sway assembly includes a first sleeve block, an anti-sway plate, a second sleeve block, a threaded hole, and a fixing bolt. The first sleeve block is disposed on the surface of the gear protective cover, and the second sleeve block is disposed on the surface of the protective cover body. The first sleeve block and the second sleeve block are in the same plane. The anti-sway plate is inserted into the second sleeve block, and the other end of the anti-sway plate extends into the interior of the first sleeve block. The threaded hole is opened on the second sleeve block. The fixing bolt is disposed on the end face of the anti-sway plate near the second sleeve block, and one end of the fixing bolt passes through the anti-sway plate and is threadedly connected to the threaded hole.
[0013] The beneficial effects of this utility model are:
[0014] By installing protective components that cover the sides of the chassis frame, the gears, rollers, and other chassis components on the chassis frame are protected inside. This prevents gravel and sharp objects from contacting the chassis components, solving the problem in the existing technology where the gears, rollers, and other chassis components inside the tracked chassis of the muck loader are exposed and directly contacted by gravel and sharp objects, which accelerates the wear of the chassis components and causes the chassis to get stuck on the gears and rollers, resulting in chassis damage.
[0015] By setting up a gear protective cover and an anti-sway component, the gear protective cover is designed to rotate, and the anti-sway component stabilizes the gear protective cover. In this way, when the anti-sway component is disengaged, the gear protective cover can rotate on its own. This allows the gear position to be opened for independent maintenance and repair without having to remove the entire protective cover. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0022] refer to Figure 1-3 In this embodiment, a chassis frame 1 is included. A track body 2 is provided on the side of the chassis frame 1. A protective component 3 is provided on the side of the chassis frame 1. The protective component 3 includes a protective cover 4 and a mounting component 5. The mounting component 5 is provided on the side of the chassis frame 1. The protective cover 4 is mounted on the side of the chassis frame 1 through the mounting component 5. The side of the protective cover 4 is movably attached to the inner wall of the track body 2. A flexible rubber ring 6 is provided on the side of the protective cover 4 to increase the sealing between the protective cover 4 and the track body 2. The flexible rubber ring 6 is attached to the inner wall of the track body 2, so that gaps are not easily generated when the track body 2 rotates. A guide shovel 7 is provided on the side of the protective cover 4 near the bottom. The guide shovel 7 mainly shovels gravel and sharp objects to the outside of the track body 2 when the track body 2 rotates, preventing them from staying on the track body 2 and possibly bypassing the protective cover 4 to enter the chassis components.
[0023] The mounting assembly 5 includes a mounting base 8, positioning blocks 9, fixing screws 10, and fixing nuts 11. The mounting base 8 is located on the side of the chassis frame 1. There are two sets of positioning blocks 9, which are symmetrically arranged on the surface of the mounting base 8 about the vertical axis of symmetry. The fixing screws 10 are fixedly connected to the axis of symmetry of the mounting base 8. The protective cover 4 is movably fitted onto the surface of the positioning blocks 9, with one side of the mounting base 8 fitting against the inner side of the protective cover 4. The fixing nuts 11 are threaded onto the surface of the fixing screws 10 and fit against the side of the protective cover 4. There are two sets of fixing nuts 11, both of which are threaded onto the surface of the fixing screws 10. The two sets of designs improve the stability of the protective cover 4 during installation. During operation, the protective cover 4 is first placed on the side of the positioning block 9, so that the inner side of the protective cover 4 is in contact with the surface of the mounting base 8. At this time, the fixing screw 10 passes through the protective cover 4 and extends to the outside of the protective cover 4. The positioning block 9 performs preliminary positioning of the protective cover 4. Then, the two sets of fixing nuts 11 are respectively fitted onto the surface of the fixing screw 10 to stably install the protective cover 4 on the mounting base 8 to prevent the protective cover 4 from moving, thereby realizing the rapid installation of the protective cover 4. The protective cover 4 covers the surface of the chassis component to protect it, preventing the chassis component from being exposed and accelerated by gravel and sharp objects or getting stuck on the chassis component and causing damage.
[0024] refer to Figure 1-3In this embodiment, the protective assembly 3 further includes a gear protective kit, which includes a gear protective cover 12 and an anti-sway assembly 13. The gear protective cover 12 is rotatably connected to one end face of the protective cover body 4 via a hinge. The anti-sway assembly 13 is disposed on the surfaces of the gear protective cover 12 and the protective cover body 4. The anti-sway assembly 13 includes a first sleeve block 14, an anti-sway plate 15, a second sleeve block 16, a threaded hole 17, and a fixing bolt 18. The first sleeve block 14 is disposed on the surface of the gear protective cover 12, and the second sleeve block 16 is disposed on the surface of the protective cover body 4. The first sleeve block 14 and the second sleeve block 16 are in the same plane. The anti-sway plate 15 is inserted into the second sleeve block 16, and the other end of the anti-sway plate 15 extends into the interior of the first sleeve block 14. The threaded hole 17 is opened on the second sleeve block 16. The fixing bolt 18 is disposed on the end face of the anti-sway plate 15 near the second sleeve block 16. One end of the fixing bolt 18 passes through the anti-sway plate 15 and is threaded into the threaded hole 17. Since the driving gear is a power-driven gear, a gear protection kit is independently designed at this position. The gear protection cover 12 covers the position of the power-driven gear to protect it. Then, the anti-sway component 13 stabilizes the gear protection cover 12 to prevent it from shaking. When the power-driven gear needs to be maintained or repaired, the fixing bolt 18 needs to be rotated to separate it from the threaded hole 17. Then, the anti-sway plate 15 is moved away from the first sleeve block 14. At this time, the anti-sway plate 15 will separate from the first sleeve block 14. The anti-sway plate 15 can be moved as needed, as long as it does not block the rotation of the gear protection cover 12. Then, the gear protection cover 12 is rotated so that it can be rotated through the hinge. In this way, the gear protection cover 12 is opened, which facilitates the maintenance and repair of the power-driven gear.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
