[0002] Modular, easily assembled and disassembled tracked fully hydraulic tunnel drilling rigs, with their flexible modular design and powerful tracked mobility, are well-suited for various tunnel engineering scenarios with complex geological conditions, relatively confined spaces, and variable operating environments. Whether in tunnel excavation and exploration operations in underground mines such as coal and metal mines, or in tunnel construction and water conservancy culvert construction projects, they can precisely control drilling operations with their fully hydraulic system, quickly adapt to different tunnel terrains, efficiently complete drilling tasks, and provide reliable geological data support and construction assurance for engineering projects.

[0003] However, existing technologies still have the following problems: In existing tunnel drilling rig transmission technology, there is often a problem that the transmission structure design is not reasonable enough, resulting in large losses during power transmission. This leads to the inefficient transmission of power generated by the motor to the tracks, resulting in insufficient power for the drilling rig, difficulty in moving in complex tunnel environments, low drilling efficiency, and inability to meet the needs of actual engineering for efficient operation.

[0004] To address the aforementioned problems, the inventors proposed a modular, tracked, fully hydraulic tunnel drilling rig that is easy to assemble and disassemble. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3 As shown, this utility model provides a modular tracked fully hydraulic tunnel drilling rig that is easy to assemble and disassemble. It includes a track mounting frame 1, a transmission mechanism 2 on the outer side of the track mounting frame 1, and a guide mechanism 3 on the outer side of the transmission mechanism 2. The transmission mechanism 2 includes two motors 20, which are symmetrically fixed on one side of the track mounting frame 1. A drive shaft 27 is fixedly mounted on the output end of each motor 20. A drive sprocket 26 is fixedly mounted on the outer side of the drive shaft 27, and a chain 25 is meshed with the outer side of the drive sprocket 26. Both ends of the track mounting frame 1 are fixedly equipped with... A transmission frame 22 has a driven shaft 28 rotatably mounted on its inner side. A driven sprocket 24 is fixed to one end of the driven shaft 28, and its outer side meshes with the inner side of a chain 25. A transmission wheel 23 is fixed to the outer side of the driven shaft 28, and multiple equally spaced transmission teeth 21 are fixed to its outer side. When this modular, easily detachable, tracked, fully hydraulic tunnel drilling rig is in operation, two motors 20 are started. The output of the motors 20 drives the drive shaft 27 to rotate, causing the drive sprocket 26 on the drive shaft 27 to rotate accordingly. Since the drive sprocket 26 meshes with the outer side of the chain 25, the chain 25 begins to rotate. The inner side of the chain 25 meshes with the driven sprocket 24 fixed to one end of the driven shaft 28, thereby driving the driven shaft 28 to rotate within the transmission frame 22. The drive wheel 23 on the outside of the driven shaft 28 also rotates. The drive teeth 21 on the drive wheel 23, which are evenly spaced, mesh with the drive block 31 on one side of the track plate 30, thereby transmitting power to the track plate 30, causing the track plate 30 to start running and realizing the movement of the drilling rig.

[0016] The guiding mechanism 3 includes multiple track plates 30, which are rotatably connected to each other. One side of the track plate 30 is engaged with the transmission tooth 21. Multiple support frames 37 are fixedly provided on the upper and lower surfaces of the track assembly frame 1. Support shafts 33 are fixedly provided on the inner side of the multiple support frames 37. Support wheels 32 are rotatably provided on the outer side of the support shafts 33. The outer side of the support wheels 32 slides against one side of the track plate 30. Multiple guide frames 35 are fixedly provided on the upper and lower surfaces of the track assembly frame 1. The inner side of the guide frames 35 is against one side of the track plate 30. When the transmission mechanism 2 drives the track plates 30 to rotate, the multiple track plates 30 are rotatably connected to form a continuous track. A support wheel 32 is rotatably mounted on the support shaft 33 inside the support frame 37 on the upper and lower surfaces of the track assembly frame 1. The outer side of the support wheel 32 slides against one side of the track piece 30, providing support for the track piece 30, reducing friction between the track piece 30 and the track assembly frame 1, and ensuring smooth operation of the track piece 30. At the same time, the inner side of the guide frame 35 on the upper and lower surfaces of the track assembly frame 1 is in contact with one side of the track piece 30, and the inner side of the groove 34 on the upper surface of the guide frame 35 slides against the transmission block 31, restricting and guiding the movement direction of the track piece 30, preventing the track piece 30 from deviating or derailing during operation, and ensuring that the track piece 30 operates stably along the predetermined trajectory.

[0017] The two assembly slots 4 on one side of the track assembly frame 1 provide precise positioning and fixing positions for the installation of other parts of the drilling rig, making it convenient for workers to quickly and accurately assemble parts, improving assembly efficiency, and also enhancing the stability of the connection between parts.

[0018] The transmission block 31 fixed on one side of the track piece 30 engages with the transmission tooth 21. This design makes power transmission more precise and stable, reduces power loss during transmission, improves transmission efficiency, and ensures reliable operation of the track piece 30. Multiple openings 36 on the upper and lower surfaces of the track assembly frame 1 fit snugly against the outer side of the support wheel 32, reducing the weight of the track assembly frame 1, facilitating observation of the working status of the support wheel 32, and also providing some heat dissipation, extending the service life of the support wheel 32. The groove 34 on the upper surface of the guide frame 35 slides against the transmission block 31, further enhancing the guiding effect of the guide mechanism 3 on the track piece 30, making the track piece 30 more stable during operation, reducing swaying and deviation, and improving the stability of the drilling rig's movement. Multiple fixing bolts 38 inserted on the outer side of the support frame 37 are fixedly engaged with the track assembly frame 1. This fixing method is simple and reliable, facilitating disassembly and replacement of the support frame 37 when needed, reducing maintenance costs, and improving the maintainability of the equipment.

[0019] Working Principle: When a modular, easily detachable, tracked, fully hydraulic tunnel drilling rig is in operation, two motors 20 are started. The output of the motors 20 drives the drive shaft 27 to rotate, and the drive sprocket 26 on the drive shaft 27 rotates accordingly. Since the drive sprocket 26 is engaged with the outer side of the chain 25, the chain 25 begins to rotate. The inner side of the chain 25 engages with the driven sprocket 24 fixed to one end of the driven shaft 28, thereby driving the driven shaft 28 to rotate inside the transmission frame 22. The transmission wheel 23 on the outer side of the driven shaft 28 also rotates. The equally spaced transmission teeth 21 on the transmission wheel 23 engage with the transmission block 31 on one side of the track plate 30, thereby transmitting power to the track plate 30, causing the track plate 30 to start rotating, thus realizing the movement of the drilling rig.

[0020] When the transmission mechanism 2 drives the track plates 30 to rotate, multiple track plates 30 are rotatably connected to form a continuous track. A support wheel 32 is rotatably mounted on the support shaft 33 inside the support frame 37 on the upper and lower surfaces of the track assembly frame 1. The outer side of the support wheel 32 slides against one side of the track plate 30, providing support for the track plate 30, reducing friction between the track plate 30 and the track assembly frame 1, and ensuring smooth operation of the track plate 30. Simultaneously, the inner side of the guide frame 35 on the upper and lower surfaces of the track assembly frame 1 is against one side of the track plate 30, and the inner side of the groove 34 on the upper surface of the guide frame 35 slides against the transmission block 31, restricting and guiding the movement direction of the track plate 30, preventing it from deviating or derailing during operation, and ensuring stable operation of the track plate 30 along a predetermined trajectory.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
