Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a cab structure and engineering machinery. Background Technology

[0002] Down-the-hole (DH) drills are a new type of high-efficiency, energy-saving, and widely applicable open-pit hydraulic rock drilling equipment. They are widely used in various construction applications such as foundation excavation, water conservancy, power plants, transportation, and mining. In my country's infrastructure construction sectors, including mining, energy, and national defense, DH drills play a vital role as a fundamental piece of equipment in rock drilling.

[0003] In some application scenarios, due to the harsh construction environment, safety railings need to be installed outside the cab to protect the windshield and prevent glass breakage and personnel injury. Because of the harsh mining environment and high dust levels, which are also generated during drilling, the windshield of the drilling rig cab needs to be cleaned regularly and promptly. Otherwise, the dust on the windshield can easily obstruct the driver's vision, posing a safety hazard. However, since there are safety railings at the front and top of the cab, cleaning is usually done by wiping the cab glass through the grille holes of the railings, which is inconvenient and ineffective. Removing the railings makes cleaning easier, but reinstalling them is more troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a cab structure that facilitates the cleaning of the cab glass and the installation of guardrails.

[0005] This utility model provides a cab structure, including a cab body and at least one guardrail disposed on the cab body. One side of the guardrail is hinged to the cab body via a hinge member, and at least one opposite side of the guardrail is detachably connected to the cab body.

[0006] Furthermore, the hinge is a hinge or a pivot.

[0007] Furthermore, the guardrail is provided with a first connecting part, which is at least located on the side of the guardrail away from the hinge; the cab body is provided with a second connecting part, and the first connecting part and the second connecting part are detachably connected by fasteners.

[0008] Furthermore, the hinge is located on one side of the guardrail along the first direction, and the guardrail is provided with the first connecting portion on both opposite sides along the second direction; wherein, the second direction is perpendicular to the first direction.

[0009] Furthermore, at least some of the guardrails are provided with a plurality of the first connecting portions on opposite sides along the second direction, and the plurality of the first connecting portions on each side are spaced apart along the first direction.

[0024] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0025] like Figures 1 to 5 As shown, the cab structure provided in this embodiment of the present invention includes a cab body 1 and at least one guardrail 2 disposed on the cab body 1, the guardrail 2 being located outside the cab body 1. One side of the guardrail 2 is hinged to the cab body 1 via a hinge 3, and at least the opposite side of the guardrail 2 (i.e., the side of the guardrail 2 at least away from the hinge 3) is detachably connected to the cab body 1. Specifically, the guardrail 2 is detachably connected to the cab body 1 via a detachable mechanism (not labeled in the figure), which can be disassembled by the operator, thereby separating the guardrail 2 from the cab body 1 at all locations except for the hinged joint.

[0026] When cleaning the cab glass, the detachable connection between the guardrail 2 and the cab body 1 is disassembled, allowing the guardrail 2 to rotate around the hinge 3, thus removing its obstruction of the cab glass. This facilitates convenient and quick cleaning of the cab glass, resulting in better cleaning effectiveness. After cleaning, the guardrail 2 is rotated back to its original position and then reconnected to the cab body 1. Throughout this process, the guardrail 2 remains attached to the cab body 1, facilitating its positioning and installation (completely separating the guardrail 2 from the cab body 1 would make positioning and installation difficult). This cab structure not only facilitates cleaning of the cab glass but also allows for easy installation of the guardrail 2 after cleaning. Furthermore, its simple structure makes it easy to manufacture and assemble.

[0027] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, the guardrail 2 includes a front guardrail 20A, which is located in front of the cab body 1. One side of the front guardrail 20A is hinged to the cab body 1 via a hinge 3, and at least one opposite side of the front guardrail 20A is detachably connected to the cab body 1. Simultaneously, the guardrail 2 also includes a top guardrail 20B, which is located above the cab body 1. One side of the top guardrail 20B is hinged to the cab body 1 via a hinge 3, and at least one opposite side of the top guardrail 20B is detachably connected to the cab body 1. This allows for convenient cleaning of the cab's windshield and top glass.

[0028] The front guardrail 20A can be hinged to the cab body 1 via hinge 3 on any one of its upper, lower, left, or right sides. The top guardrail 20B can be hinged to the cab body 1 via hinge 3 on any one of its front, rear, left, or right sides. In this embodiment, the lower side of the front guardrail 20A is hinged to the cab body 1 via hinge 3, and the rear side of the top guardrail 20B is hinged to the cab body 1 via hinge 3.

[0029] Of course, in other embodiments, only one of the front guardrail 20A and the top guardrail 20B may be provided, or other guardrails may be provided on the cab.

[0030] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, the hinge 3 is a hinge, and one side of the guardrail 2 is hinged to the cab body 1 via the hinge. The hinge includes a first leaf (not labeled) and a second leaf (not labeled) that are rotatably connected. The first leaf is fixedly connected to one side of the guardrail 2 (specifically, it can be connected by bolts, welding, etc.), and the second leaf is fixedly connected to the cab body 1.

[0031] In another embodiment, the hinge 3 can also be a pivot, with one side of the guardrail 2 hinged to the cab body 1 via the pivot. In this case, a first ear plate (not shown) can be provided on one side of the guardrail 2, and a second ear plate (not shown) can be provided on the cab body 1, with the first ear plate and the second ear plate hinged together by the pivot. The pivot can specifically be a pin, etc.

[0032] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, each guardrail 2 (including the front guardrail 20A and the top guardrail 20B) is provided with a first connecting part 24, which is at least located on the side of the guardrail 2 away from the hinge member 3; the cab body 1 is provided with a second connecting part 11, and the first connecting part 24 and the second connecting part 11 are detachably connected by fasteners (not shown). That is, the detachable mechanism includes the first connecting part 24, the second connecting part 11, and the fasteners. Of course, in other embodiments, the guardrail 2 and the cab body 1 can also be detachably connected by a structure such as a snap-fit ​​or a lock, that is, the detachable mechanism can also be a snap-fit ​​assembly, a lock assembly, etc.

[0033] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, the hinge 3 is located on one side of the guardrail 2 along the first direction X. The guardrail 2 has first connecting portions 24 on both opposite sides along the second direction Y. Each of the first connecting portions 24 on opposite sides is detachably connected to a corresponding second connecting portion 11 via fasteners, thus improving the connection stability between the guardrail 2 and the cab body 1. The second direction Y is perpendicular to the first direction X. A second connecting portion 11 is provided on the cab body 1 at the position corresponding to each first connecting portion 24. In this embodiment, as... Figure 2 As shown, the hinge 3 is located on one side of the front guardrail 20A along its vertical direction. The front guardrail 20A has a first connecting part 24 on both its left and right sides. That is, for the front guardrail 20A, the first direction X is the vertical direction of the front guardrail 20A, and the second direction Y is the horizontal direction of the front guardrail 20A. Figure 4 As shown, the hinge 3 is located on one side of the top guardrail 20B along its front-back direction. The top guardrail 20B is provided with a first connecting part 24 on both the left and right sides. That is, for the top guardrail 20B, the first direction X is the front-back direction of the top guardrail 20B, and the second direction Y is the left-right direction of the top guardrail 20B.

[0034] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, at least some of the guardrails 2 are provided with multiple first connecting portions 24 on opposite sides along the second direction Y, and the multiple first connecting portions 24 on each side are spaced apart along the first direction X; this can further improve the connection stability between the guardrails 2 and the cab body 1. In this embodiment, as... Figure 2As shown, the front guardrail 20A has multiple first connecting parts 24 on both its left and right sides, and the multiple first connecting parts 24 on each side are spaced apart in the vertical direction; as shown Figure 4 As shown, a first connecting portion 24 is provided on each of the left and right sides of the top protective railing 20B. Of course, in other embodiments, multiple first connecting portions 24 may also be provided on each of the left and right sides of the top protective railing 20B.

[0035] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, the first connecting part 24 is a connecting plate, which can be fixed to the guardrail 2 by welding or integrally connected. The second connecting part 11 is a threaded seat with a threaded hole; the threaded seat protrudes from the surface of the cab body 1, and the threaded seat can be a columnar structure; the threaded seat can be fixed to the cab body 1 by welding. The fastener is a screw, that is, the first connecting part 24 and the second connecting part 11 are connected by screws. When cleaning the cab glass, the screws between the guardrail 2 and the cab body 1 are removed, and then the guardrail 2 is rotated around the hinge 3 before cleaning the cab glass; after cleaning, the guardrail 2 is rotated back to its original position, and then the guardrail 2 is connected to the cab body 1 by screws. This structure is not only convenient for disassembly and assembly, but also, because the threaded seat protrudes from the surface of the cab body 1, there is a distance between the guardrail 2 and the surface of the cab body 1, that is, there is a buffer space between the guardrail 2 and the cab glass. In this way, when the guardrail 2 is subjected to external impact, it can avoid or reduce the damage to the glass caused by the contact between the guardrail 2 and the cab glass.

[0036] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, one side of the guardrail 2 is hinged to the cab body 1 by at least two (two in this embodiment) hinges 3, and the at least two hinges 3 are spaced apart along the second direction Y, thereby improving the connection stability between the guardrail 2 and the cab body 1.

[0037] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, each guardrail 2 includes multiple spaced longitudinal beams 21 and multiple spaced transverse beams 22. The longitudinal beams 21 extend along a first direction X, and the multiple longitudinal beams 21 are arranged at intervals along a second direction Y; the transverse beams 22 extend along the second direction Y, and the multiple transverse beams 22 are arranged at intervals along the first direction X. The multiple longitudinal beams 21 and multiple transverse beams 22 are intersected and connected. The guardrail 2 forms grid holes 23 between adjacent longitudinal beams 21 and adjacent transverse beams 22. This not only gives the guardrail 2 high structural strength, but also allows the driver to observe the external situation through the grid holes 23, thereby reducing the obstruction of the driver's vision caused by the guardrail 2.

[0038] In this embodiment, the longitudinal beams 21 are sheet-like structures (i.e., planar strip-shaped plate structures), and the transverse beams 22 are rod-like structures (i.e., column-like structures). Each longitudinal beam 21 has multiple through holes (not labeled in the figure), and each transverse beam 22 passes through the through holes on each longitudinal beam 21. Each transverse beam 22 is fixed to each longitudinal beam 21 by welding, which can prevent the transverse beams 22 from being interrupted by the longitudinal beams 21, thus ensuring the structural strength of the guardrail 2.

[0039] Furthermore, such as Figures 1 to 5 As shown, in this embodiment, each guardrail 2 has a mounting beam 25 on one side, which is fixedly connected to the ends of multiple longitudinal beams 21; the mounting beam 25 is connected to the hinge 3. The mounting beam 25 not only serves to install the hinge 3, but also further enhances the structural strength of the guardrail 2. In this embodiment, the mounting beam 25 is a mounting plate, and it is fixed to the ends of each longitudinal beam 21 by welding. Specifically, the mounting beam 25 on the front guardrail 20A is an L-shaped bent plate, and the mounting beam 25 on the top guardrail 20B is a flat strip plate.

[0040] This embodiment also provides an engineering machine, including the cab structure described above. The engineering machine includes, but is not limited to, equipment with a cab such as a down-the-hole drill rig or an excavator.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
