Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt conveyor for switching transport paths. Background Technology

[0002] Belt conveyors (also known as conveyor belts or conveyor belts) are mechanical equipment used for material handling and are widely used in industries such as mining, metallurgy, chemical industry, building materials, power, and food processing.

[0003] When a tunnel boring machine (TBM) is working, two sets of hoists are needed to lift the materials generated during construction out of the tunnel shaft. A single tunnel shaft typically requires multiple TBMs to operate simultaneously, necessitating the use of belt conveyors to move the materials to the hoists. However, due to limited space within the tunnel shaft, only two hoists are usually installed. If one hoist fails, the repair cycle is lengthy, requiring a change in the original belt conveyor's transport path. The faulty hoist's transport path must be disconnected, and the materials lifted to the surface by the working hoist. However, existing belt conveyors are mostly fixed structures, making it difficult to switch transport paths during operation.

[0004] In summary, how to design a belt conveyor that can switch transport paths has become a technical problem that urgently needs to be solved by those in this field. Utility Model Content

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a belt conveyor for switching transport paths, including a support mechanism 1 and a conveying mechanism 5. A first support plate 2 and a second support plate 3 are fixedly installed at the bottom of the conveying mechanism 5. The support mechanism 1 is rotatably connected to the bottom of the first support plate 2 and the second support plate 3. A position adjustment mechanism 4 for driving the conveying mechanism 5 to rotate and move along the support mechanism 1 is provided between the support mechanism 1 and the second support plate 3. A tensioning mechanism 6 is provided on the support mechanism 1 to prevent the position of the conveying mechanism 5 from shifting.

[0021] The conveying mechanism 5 is mounted on the support mechanism 1 via the first support plate 2 and the second support plate 3. The conveying mechanism 5 can be rotated and adjusted along the support mechanism 1. During the position adjustment, it can be mechanically adjusted by the position adjustment mechanism 4, so that the conveying mechanism 5 corresponds to the position of the tunnel boring machine, which facilitates the movement of materials to the hoist position. The conveying mechanism 5 can also prevent the conveyor belt 25 from deviating during material conveying, ensuring accurate material transportation. The tensioning mechanism 6 can support the conveyor belt 25 to prevent the conveyor belt 25 from becoming too loose.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The support mechanism 1 includes a first fixed seat 7, a first fixed frame 8, a first rotating seat 9, a second fixed seat 10, a second fixed frame 11, a reinforcing plate 12, and support columns 13. The second fixed frame 11 is configured in two sets. The first fixed frame 8 and the second fixed frame 11 are fixedly connected by the reinforcing plate 12. The first fixed seat 7 and the second fixed seat 10 are fixedly installed at the bottom of the first fixed frame 8 and the second fixed frame 11, respectively. The top of the first fixed frame 8 is rotatably connected to the first support plate 2 through the first rotating seat 9. The top of the second fixed frame 11 is fixedly installed with a third support plate 15. Multiple sets of support columns 13 are fixedly installed at the bottom of the second support plate 3. The bottom of the support column 13 is rotatably connected with support balls 14 that fit against the third support plate 15.

[0023] The first fixed frame 8 is rotatably connected to the first support plate 2 via the first rotating seat 9, while the support column 13 and support ball 14 at the bottom of the second support plate 3 can fit against the third support plate 15 on the second fixed frame 11. This allows the conveying mechanism 5 to rotate along the first rotating seat 9 and to be supported and limited by the support ball 14.

[0024] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The conveying mechanism 5 includes a mounting plate 20, a first rotating shaft 21, a pulley 22, a positioning groove 23, and a conveyor belt 25. Two sets of first rotating shafts 21 are rotatably mounted on the mounting plate 20. A pulley 22 is fixedly mounted on the outside of the first rotating shaft 21. Multiple positioning grooves 23 are opened on the pulley 22. A second drive motor 24 is fixedly mounted on one side of the mounting plate 20. The output end of the second drive motor 24 is fixedly connected to the first rotating shaft 21. A conveyor belt 25 is provided on the outside of the pulley 22. A positioning block 26 that is inserted into the positioning groove 23 is provided on the inner wall of the conveyor belt 25.

[0025] During material conveying, the positioning block 26 at the bottom of the conveyor belt 25 can be engaged into the positioning groove 23. This prevents the conveyor belt 25 from shifting or misaligning when the pulley 22 drives it to rotate. When the conveying mechanism 5 is working, the second drive motor 24 operates, which drives the first rotating shaft 21 and the pulley 22 to rotate, thus driving the conveyor belt 25 to rotate and facilitating material conveying.

[0026] Please see Figure 1 , Figure 2 and Figure 3 The position adjustment mechanism 4 includes a gear ring 16, a first mounting bracket 17, a first drive motor 18, and a gear disk 19. The gear ring 16 is fixedly installed on one side of the third support plate 15. The gear ring 16 is coaxial with the first rotating seat 9. The first drive motor 18 is fixedly installed on the bottom of the second support plate 3 through the first mounting bracket 17. The output end of the first drive motor 18 is fixedly connected to the gear disk 19 that meshes with the gear ring 16.

[0027] When the position of the conveying mechanism 5 needs to be adjusted, the first drive motor 18 operates, and the first drive motor 18 drives the gear disk 19 to rotate, so that the gear disk 19 can rotate along the gear ring 16, and thus the conveying mechanism 5 can rotate and be adjusted along the first rotating seat 9.

[0028] Please see Figure 1 , Figure 2 and Figure 3 The tensioning mechanism 6 includes a second mounting bracket 29, a threaded sleeve 30, a threaded rod 31, a second rotating seat 32, and a positioning ring 33. The second mounting bracket 29 is fixedly mounted on the side wall of the mounting plate 20. The threaded sleeve 30 is provided on the second mounting bracket 29. The threaded rod 31 is threadedly connected to the inside of the threaded sleeve 30. The bottom of the threaded rod 31 is rotatably connected to the positioning ring 33 through the second rotating seat 32. The second rotating shaft 34 is rotatably connected to the inside of the positioning ring 33. The pressure roller 35 is fixedly mounted on the outside of the second rotating shaft 34.

[0029] When the conveyor belt 25 becomes loose, the threaded rod 31 is rotated, causing it to move upward along the inside of the threaded sleeve 30. This causes the second rotating seat 32 and the positioning ring 33, which are rotatably connected to the threaded rod 31, to move upward. This, in turn, pulls the second rotating shaft 34 and the pressure roller 35 upward, allowing the pressure roller 35 to squeeze the conveyor belt 25. This prevents the conveyor belt 25 from becoming excessively loose.

[0030] Please see Figure 1 , Figure 4 and Figure 5A limiting plate 27 is fixedly installed on the mounting plate 20. An inclined guide plate 28 is fixedly installed on both sides of the limiting plate 27. The limiting plate 27 can support the conveyor belt 25 to prevent the conveying efficiency from being affected when the material is conveyed. The inclined guide plate 28 can prevent the limiting plate 27 from affecting the movement of the positioning block 26 and the conveyor belt 25 when the conveyor belt 25 is loose.

[0031] The working principle of this utility model is as follows:

[0032] During operation, the conveying mechanism 5 is first mounted on the support mechanism 1 via the first support plate 2 and the second support plate 3. The conveying mechanism 5 can be rotated and adjusted along the support mechanism 1, and this adjustment is achieved mechanically via the position adjustment mechanism 4. This allows the conveying mechanism 5 to align with the tunnel boring machine, facilitating the movement of materials to the hoist position. The conveying mechanism 5 also prevents the conveyor belt 25 from shifting during material transport, ensuring accurate material delivery. The tensioning mechanism 6 supports the conveyor belt 25, preventing it from becoming too loose. The first fixed frame 8 is rotatably connected to the first support plate 2 via the first rotating seat 9. The support column 13 and support ball bearings 14 at the bottom of the second support plate 3 can engage with the third support plate 15 on the second fixed frame 11. This allows the conveying mechanism 5 to rotate along the first rotating seat 9, and the support ball bearings 14 provide support and limit the movement. During material transport, the positioning block 26 at the bottom of the conveyor belt 25... It can be inserted into the positioning groove 23, which can prevent the conveyor belt 25 from shifting or misaligning when the pulley 22 drives the conveyor belt 25 to rotate. When the conveyor mechanism 5 is working, the second drive motor 24 operates, which can drive the first rotating shaft 21 and the pulley 22 to rotate, thus driving the conveyor belt 25 to rotate, facilitating the conveying of materials. When the position of the conveyor mechanism 5 needs to be adjusted, the first drive motor 18 operates, which drives the gear disk 19 to rotate, thus allowing the gear disk 19 to rotate along the gear ring 16, thereby allowing the conveyor mechanism 5 to rotate and adjust along the first rotating seat 9. When the conveyor belt 25 becomes loose, the threaded rod 31 is rotated, causing the threaded rod 31 to move upward along the inside of the threaded sleeve 30, which can drive the second rotating seat 32 and the positioning ring 33, which are rotatably connected to the threaded rod 31, to move upward, thereby pulling the second rotating shaft 34 and the pressure roller 35 upward, so that the pressure roller 35 can squeeze the conveyor belt 25, thus preventing the conveyor belt 25 from becoming excessively loose.

[0033] It should be noted that the conveyor belt of this utility model with a switching transport path has its feed end located below the discharge end of the shield tunnel muck output conveyor belt, and its discharge end located above the lower-level conveyor belt. Multiple lower-level conveyor belts transport the muck horizontally to multiple hoists inside the shield tunnel shaft. When a hoist connected to a lower-level conveyor belt fails, the conveyor belt of this utility model with a switching transport path can be twisted to achieve the switching of multiple lower-level conveyor belts.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
