[0001] The utility model relates to the technical field of construction equipment, in particular to a tunneling arm device and tunneling equipment. Background Art

[0002] With the development of mining and tunnel construction, the demand for tunneling equipment capable of operating efficiently in hard rock conditions is increasing. In recent years, the use of breaker hammers for tunneling has gained increasing attention. Breakers, as tools that break rock through impact, are capable of handling rock formations with hardness exceeding 80 MPa.

[0003] However, in complex construction sites, fixed-position breakers have a limited working range, making them unable to reach targets far from the main unit. This is particularly restrictive when working on large structures or deep layers. Furthermore, fixed-position breakers may not be able to adjust the impact force based on the hardness and size of the target, which can easily lead to over-impact when breaking softer or partially broken materials, and insufficient force when breaking harder materials.

DETAILED DESCRIPTION

[0024] In the tunneling device in the related art, the breaker hammer is often in a fixed position, and there is a problem that the impact force cannot be adjusted according to the hardness and size of the crushed target.

[0025] In response to the above problems, the present invention provides a tunneling arm device 10 and tunneling equipment, which can adjust the position of the crushing mechanism 400 through the propulsion mechanism 300 to achieve different impact forces, improve stability and reliability, and reduce energy consumption and wear.

[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 arm device 10 and the tunneling equipment provided by the present invention through embodiments and in conjunction with the accompanying drawings. Figures 1 to 3 The present application provides a tunneling arm device 10 for use in tunneling equipment, including an arm mechanism 100 , a propulsion mechanism 300 , a slide 200 , and a crushing mechanism 400 .

[0033] The crushing mechanism 400 is fixed to the upper end of the slide 200, and the slide 200 is slidably mounted on the arm mechanism 100; the propulsion mechanism 300 is disposed inside the slide 200 and is used to propel the slide 200 along the length direction of the slide ( Figure 2 The crushing mechanism 400 slides in the x-direction (shown), that is, in the crushing direction. Therefore, driven by the propulsion mechanism 300, the crushing mechanism 400 reciprocates along the crushing direction relative to the arm mechanism 100 along with the carriage 200. Adjusting the position of the crushing mechanism 400 during movement not only compensates for operational displacement but also provides preload, ensuring precise control of the impact force.

[0034] Specifically, when facing softer or partially crushed materials, the propulsion mechanism 300 is adjusted so that the distance between the crushing mechanism 400 and the working surface is smaller to avoid excessive impact; and when crushing harder materials, the propulsion mechanism 300 is adjusted so that the distance between the crushing mechanism 400 and the working surface is larger to provide sufficient pre-pressure.

[0035] It should also be noted that the carriage 200, as an intermediate structure, absorbs and dissipates the vibration and impact generated by the crushing mechanism 400 during operation. In particular, the propulsion mechanism 300 is located within the carriage 200 and is protected from direct impact. This ensures the service life of the tunneling arm assembly 10 and reduces maintenance frequency.

[0036] Therefore, based on the design of the propulsion mechanism 300 and the slide 200, it is ensured that while the striking force is accurately controlled, the stability and reliability of the equipment are improved and the energy consumption and wear are reduced.

[0037] In this application, the propulsion mechanism 300 is a telescopic cylinder comprising a cylinder barrel and a piston rod. The cylinder barrel is connected to the arm mechanism 100, while the piston rod slides with the cylinder barrel and is connected to the carriage 200. Therefore, as the piston rod extends in and out of the cylinder barrel, the carriage 200 and the propulsion mechanism 300 on the carriage 200 move forward or backward relative to the arm mechanism 100.

[0038] In some embodiments, in order to ensure the stability of the movement trajectory of the crushing mechanism 400, Figure 2 and Figure 3 As shown, the arm mechanism 100 includes a guide sleeve, and a guide pin 210 is provided within the carriage 200. The guide pin 210 slidably engages with the guide sleeve. The guide structure formed by the guide pin 210 and the guide sleeve precisely guides the carriage 200 and the crushing mechanism 400 along the crushing direction. In other embodiments, the arm mechanism 100 may also be provided with a sliding track that directly slidably engages with the carriage 200. This is not further described in this embodiment.

[0039] Furthermore, in order to improve the movement stability, the number of the guide pins 210 is at least two, and at least two guide pins 210 are arranged along the width direction of the carriage 200 (i.e. Figure 2 Accordingly, the guide sleeves and the guide pins 210 correspond one to one, that is, the quantity and position correspond one to one, to improve the stability of the movement in the system as a whole.

[0040] It is easy to understand that multiple guide pins 210 work together to provide more support points on the one hand, ensuring the stability of the shape and position of the slide 200 during the movement process, reducing unnecessary deformation and shaking; on the other hand, it more accurately guides the slide 200 to move along a predetermined path, reducing the error accumulation that may be caused by a single guide pin 210, making the movement smoother and more accurate.

[0041] Optionally, the carriage 200 is a square box with one end open. The propulsion mechanism 300 is located inside the box to prevent damage from external impact during operation. Based on the above, one end of the propulsion mechanism 300 is connected to the bottom wall of the square box, and the other end passes through the open end of the square box and connects to the arm mechanism 100, thereby improving compactness and achieving an integrated design of the device.

[0042] In some embodiments, the crushing mechanism 400 includes a hammer core 410 and a housing 430, with the hammer core 410 connected to the carriage 200 via the housing 430. It will be readily understood that the hammer core 410 is the portion of the crushing mechanism 400 that directly contacts the object being crushed and, therefore, is more susceptible to wear than the housing 430. The separate design of the hammer core 410 and the housing 430 allows for easier replacement of the hammer core 410 to suit operating conditions, saving maintenance costs and downtime.

[0043] Furthermore, considering the stability of the connection between the housing 430 and the carriage 200, the tunneling arm assembly 10 further includes bolts, through which the housing 430 is connected to the carriage 200. It will be appreciated that securing the housing 430 to the carriage 200 with bolts ensures a secure connection between the two and reduces loosening due to vibration or impact.

[0044] In some embodiments, to enhance operational flexibility and maneuverability, the boom mechanism 100 includes a boom assembly 110, a rotation assembly 130, and an arm assembly 150, all articulated in sequence. The combination of the boom assembly 110 and arm assembly 150 significantly increases the operating radius of the boom mechanism 100, enabling the device to reach further locations and adapt to a variety of operational scenarios. The introduction of the rotation assembly 130 allows the boom mechanism 100 to rotate freely, increasing its operational coverage area.

[0045] Furthermore, the boom assembly 110 is connected to the vehicle body, allowing the vehicle body to serve as a stable base for the boom mechanism 100, improving the operational stability of each joint of the boom mechanism 100. The arm assembly 150 is connected to the propulsion mechanism 300, serving as a stable base for the propulsion mechanism 300 and improving its operational stability. Optionally, both the boom assembly 110 and the arm assembly 150 are equipped with pitch hydraulic cylinders to facilitate pitch adjustment to accommodate different operating angles, thereby improving operational flexibility and adaptability.

[0046] Furthermore, to improve the operational stability of the boom mechanism 100, the boom mechanism 100 also includes a swing base 500, which is used to connect the boom assembly 110 to the vehicle body. It is easy to understand that the swing base 500 is a connecting transition piece between the boom assembly 110 and the vehicle body. On the one hand, it can effectively disperse the load between the boom assembly 110 and the vehicle body, reducing local stress concentration; on the other hand, it can also reduce vibration and impact between the boom assembly 110 and the vehicle body, improving movement stability.

[0047] Furthermore, to improve the operating efficiency of the tunneling arm assembly 10, the arm assembly 100 also includes a bucket assembly 170, which is connected to the arm assembly 150. As will be readily appreciated, the bucket and crushing mechanism 400 are integrated into the arm assembly 100, allowing the tunneling arm assembly 100 to quickly switch between crushing and excavation functions without the need for replacing or using additional equipment, thereby effectively saving time and improving overall operating efficiency.

[0048] In summary, the present application provides a tunneling arm assembly 10 comprising an arm mechanism 100, a propulsion mechanism 300, a carriage 200, and a crushing mechanism 400. The crushing mechanism 400 is fixed to the upper end of the carriage 200, which is slidably mounted on the arm mechanism 100. The propulsion mechanism 300 is located within the carriage 200 and is used to propel the carriage 200 along its length. Therefore, driven by the propulsion mechanism 300, the crushing mechanism 400 reciprocates relative to the arm mechanism 100 along with the carriage 200. Adjusting the position of the crushing mechanism 400 during movement not only compensates for construction displacement but also provides preload, ensuring precise control of impact force. The carriage 200, as an intermediate structure, absorbs and dissipates vibrations and shocks generated by the crushing mechanism 400 during operation. In particular, the propulsion mechanism 300 is located within the carriage 200 and is protected by the carriage 200 from direct impact. Based on this, the service life of the tunneling arm device 10 is guaranteed and the maintenance frequency of the tunneling arm device 10 is reduced.

[0049] In addition, the present application also provides a tunneling device, specifically tunneling equipment, mining equipment, and underground engineering equipment, which includes a tunneling arm device 10 and a vehicle body, wherein the tunneling arm device 10 is connected to the vehicle body. It is easy to understand that because the tunneling device includes the tunneling arm device 10, it can also improve the stability and reliability of the device while accurately controlling the impact force, and reduce energy consumption and wear.

[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.
