DETAILED DESCRIPTION

[0024] The tunneling arm in the related art has the problems of limited arm pitch adjustment angle, small working range, low efficiency, and difficulty for the breaker hammer to perform top tunneling in narrow tunnels.

[0025] In response to the above problems, the utility model provides a tunneling arm device and tunneling equipment, which can increase the pitch angle of the arm assembly, increase the working surface of the breaker hammer, and improve the convenience of top tunneling in narrow tunnels.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0030] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0032] The following describes in detail the overall structure, working principle and technical effects of the tunneling device and tunneling equipment provided by the present invention through embodiments and in conjunction with the accompanying drawings. Figure 1 , Figure 1 Schematic diagram of the structure of the tunneling arm device 10 provided in this embodiment. The present application provides a tunneling arm device 10, which is used in tunneling equipment and includes a boom assembly 100, an arm assembly 400, a connecting rod assembly 300 and a breaker hammer 700.

[0033] The connecting rod assembly 300 includes a first connecting rod 310, a second connecting rod 330, and a connecting rod driver 350, each hinged at one end. Furthermore, the other end of the first connecting rod 310 is hinged to the arm assembly 400, while the other end of the second connecting rod 330 is hinged to the boom assembly 100. Driven by the connecting rod driver 350, the first connecting rod 310 and the second connecting rod 330 extend or contract about their common rotational center, thereby causing the arm assembly 400 to produce corresponding pitch motion relative to the boom assembly 100.

[0034] On this basis, the breaker hammer 700 is connected to the arm assembly 400 and moves downward simultaneously with the arm assembly 400 when it moves forward, or moves upward simultaneously with it when it moves backward. Based on this, it can be seen that under the action of the connecting rod driving member 350, the first connecting rod 310, and the second connecting rod 330, the pitch angle of the arm assembly 400 is increased, and the working surface of the breaker hammer 700 is increased, thereby smoothly carrying out top excavation in narrow tunnels.

[0035] Optionally, both the first connecting rod 310 and the second connecting rod 330 are configured as curved rods. As will be readily appreciated, the curved shape of the curved rod naturally avoids direct contact with other mechanical components during movement, reducing the possibility of interference. Alternatively, the connecting rod driver 350 can be configured as a telescopic cylinder, with the cylinder base articulated with the first connecting rod 310 and the second connecting rod 330, and the telescopic rod connected to the arm assembly 400.

[0036] In the embodiment provided herein, to improve tunneling efficiency, the tunneling arm assembly 10 further includes a power assembly 510. The breaker hammer 700 is connected to the arm assembly 400 via the power assembly 510 and, under the action of the power assembly 510, slides or rotates relative to the arm assembly 400 to preload crushing energy and improve crushing efficiency.

[0037] In some embodiments, see Figure 2 and Figure 3 The arm assembly 400 includes two mounting plates 410 positioned opposite each other and a pin hingedly connected to the two mounting plates 410. To ensure a compact structure for the tunneling arm assembly 10, the connecting rod driver 350 is located between the two mounting plates 410 and hingedly connected to the two mounting plates 410 via a first pin. Alternatively, two first connecting rods 310 may be provided, each connected to one of the two mounting plates 410, to ensure smooth pitch adjustment of the arm assembly 400.

[0038] Further, please refer again to Figure 1 and Figure 2 The tunneling arm assembly 10 also includes a bucket 610, a bucket driver 630, and a second pin, which facilitate material excavation, tunneling, and work surface finishing. The bucket 610 is hingedly connected to the two mounting plates 410 via the second pin. The bucket driver 630 is located on the side of the mounting plates 410 away from the connecting rod driver 350, and its ends are hingedly connected to the mounting plates 410 and the bucket 610, respectively.

[0039] As can be seen from the foregoing description, the connecting rod driver 350 is located between the two mounting plates 410 and is internal to the arm assembly 400; while the bucket driver 630 is located outside the two mounting plates 410 and is external to the arm assembly 400. In other words, the connecting rod driver 350 and the bucket driver 630 are located at different positions within the arm assembly 400. This, on the one hand, facilitates shortening the length of the tunneling arm assembly 10, improving space utilization and structural compactness; on the other hand, it improves motion stability and reliability and reduces potential motion interference between the bucket drivers. Preferably, there are two bucket drivers 630, one located outside each of the two mounting plates 410.

[0040] In the embodiments provided in this application, Figure 1 and Figure 4 As shown, to increase the flexibility of the tunneling arm assembly 10, the tunneling arm assembly 10 also includes a rotation assembly 200. The end of the second connecting rod 330, which is remote from the connecting rod driver 350, is hingedly connected to the boom assembly 100 via the rotation assembly 200. Combined with the aforementioned connection between the second connecting rod 330 and the arm assembly 400 via the connecting rod driver 350, it can be seen that the arm assembly 400 can rotate relative to the boom assembly 100 via the rotation assembly 200, thereby expanding the working area, shortening the construction schedule, and improving the quality of the project.

[0041] Specifically, the rotating assembly 200 includes a rotating disk 210 and a rotating drive 230. The end of the second connecting rod 330, distal from the connecting rod drive 350, is hingedly connected to the boom assembly 100 via the rotating disk 210. Specifically, the rotating disk 210 is located between the arm assembly 400 and the boom assembly 100, resulting in a compact design and space savings. The rotating drive 230 is in driving connection with the rotating disk 210, enabling it to rotate 360° in a single direction, or 180° in both the counterclockwise and clockwise directions.

[0042] Optionally, two rotary drive members 230 are provided to provide greater output torque and overturning moment. Furthermore, the two rotary drive members 230 are symmetrically arranged about the axis of the rotary disk 210 to provide more uniform torque output, making the rotary disk 210 more stable during operation and improving operational efficiency and dynamic performance. Based on calculations and selection, the rotary drive member 230 is a drive motor.

[0043] Furthermore, to optimize stability during movement, the rotating assembly 200 and the slewing rotating assembly 200 also include a slewing arm 250. The end of the second connecting rod 330, which is remote from the connecting rod driver 350, is hingedly connected to the slewing disc 210 via the slewing arm 250. The configuration of the slewing arm 250 enables the slewing movement of the arm assembly 400 and the breaker 700 while better distributing the load, reducing unbalanced loads, and minimizing shaking, thereby improving the stability and reliability of the system.

[0044] like Figure 4 As shown, to further enhance the flexibility and convenience of the tunneling arm assembly 10, the boom assembly 100 includes a boom weldment 110 and a boom driver 130. One end of the boom weldment 110 is hinged to the first connecting rod 310, and the other end is hinged to the vehicle frame. Furthermore, one end of the boom driver 130 is hinged to the boom weldment 110, and the other end is hinged to the vehicle frame, thereby driving the boom weldment 110 in pitch relative to the vehicle frame.

[0045] Furthermore, the tunneling arm assembly 10 also includes a swing base 800, which is used to connect the boom weldment 110 and the vehicle frame, and also to connect the boom drive unit 130 and the vehicle frame. It is easy to understand that the swing base 800 serves as a connecting transition piece between the boom assembly 100 and the vehicle frame. On the one hand, it can effectively distribute the load between the boom weldment 110 and the vehicle frame, reducing local stress concentration; on the other hand, it can also reduce vibration and impact between the boom drive unit 130 and the vehicle frame, improving movement stability.

[0046] It's easy to understand that the working length and height of the tunneling arm assembly 10 can be adjusted based on the configuration of the power assembly 510, bucket driver 630, connecting rod driver 350, slewing driver 230, and boom driver 130. For example, when operating in a low-lying tunnel, the boom driver 130 can be shortened to lower the working height; the connecting rod driver 350, power assembly 510, and bucket driver 630 can then be extended to meet the required excavation distance.

[0047] In addition, it should be noted that the hinges mentioned in the above description can all be achieved through pins, which will not be described in detail in this application.

[0048] In summary, the present application provides a tunneling arm assembly 10, comprising a boom assembly 100, an arm assembly 400, a connecting rod assembly 300, and a breaker hammer 700. The connecting rod assembly 300 includes a first connecting rod 310, a second connecting rod 330, and a connecting rod driver 350, hinged at one end. Furthermore, the other end of the first connecting rod 310 is hinged to the arm assembly 400, while the other end of the second connecting rod 330 is hinged to the boom assembly 100. Driven by the connecting rod driver 350, the first connecting rod 310 and the second connecting rod 330 extend or contract about a common rotational center point, thereby causing the arm assembly 400 to produce corresponding pitching motion relative to the boom assembly 100. Furthermore, the breaker hammer 700 is connected to the arm assembly 400 and moves downward with the arm assembly 400 as it moves forward, or upward with it as it moves backward. Based on this, it means that under the action of the connecting rod driving member 350, the first connecting rod 310 and the second connecting rod 330, the pitch angle of the arm assembly 400 is increased, and the working surface of the breaker hammer 700 is increased, so that the top excavation in the narrow tunnel can be carried out smoothly.

[0049] In addition, the present application also provides a tunneling device, which can be specifically tunnel engineering equipment, mining engineering equipment, and underground engineering equipment, which includes a vehicle frame and the tunneling arm device 10 of the aforementioned embodiment, and the vehicle frame is connected to the tunneling arm device 10. It is easy to understand that because the tunneling device includes the tunneling arm device 10, it can also increase the pitch angle of the small arm assembly 400, increase the working surface of the breaker 700, and improve the convenience of top tunneling in narrow tunnels.

[0050] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
