Description

Technical Field

[0001] This utility model relates to the technical field of TBM slag discharge, and in particular to a rapid slag discharge device for TBM. Background Technology

[0002] TBM, or tunnel boring machine, also known as shield tunneling machine, is a large-scale mechanized construction equipment specifically used for the excavation and lining of underground tunnels. The front of the TBM is the main unit, with dozens of cutters mounted on the cutterhead. By rotating and applying pressure, it cuts out the entire circular cross-section, completing operations such as rock breaking. Then, the excavated rock enters the main unit's belt conveyor through the cutterhead, and is then output through a continuous belt conveyor before finally being loaded onto trucks and transported out.

[0003] After passing through the main conveyor, the slag and stone fall onto the subsequent belt conveyor via a hopper at one end. Because they fall from the main conveyor and through the hopper onto the subsequent belt conveyor, some larger pieces of slag and stone can damage the belt, reducing its service life. Therefore, in existing technology, multiple inclined baffles are often installed under the hopper to prevent slag and stone from falling directly onto the subsequent belt conveyor. The slag and stone roll or slide down the inclined baffle surface onto the subsequent belt conveyor, effectively reducing the impact and thus mitigating belt damage. However, some problems still exist that need improvement during use:

[0004] As the slag rolls or slides down the inclined baffle onto the conveyor belt, the slag is powered only by gravity and the pushing force of subsequent slag. In order to avoid a large impact when the slag falls, the inclination of the baffle is generally small. Therefore, the slag may not be able to move on the inclined baffle or move slowly, which in turn makes the speed of the slag entering the subsequent belt conveyor slow, resulting in low slag discharge efficiency and inability to discharge slag quickly.

[0005] Therefore, there is an urgent need for a slag discharge device that can discharge slag quickly without causing significant damage to the conveyor belt. Utility Model Content

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0056] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0057] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0058] Furthermore, the terms “, second”, “third”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0059] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0060] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0062] It should be understood that during the process of the slag rolling or sliding down the inclined baffle 2 onto the belt conveyor, since the power source of the slag is only gravity and the pushing of subsequent slag, and in order to avoid a large impact when the slag falls, the inclination of the baffle 2 is generally small. Therefore, the slag may not be able to move on the inclined baffle 2, or may move slowly, which in turn makes the speed of the slag entering the subsequent belt conveyor 3 slower, resulting in low slag discharge efficiency and inability to discharge slag quickly.

[0063] To address the aforementioned issues, this embodiment provides a rapid slag removal device for TBMs, primarily comprising a housing 1, multiple baffles 2, and a belt conveyor. This device is mainly used during TBM construction, enabling rapid slag removal while also mitigating damage to the belt conveyor from the slag, thereby extending its service life.

[0064] In this embodiment, as Figure 1 As shown, the shell 1 adopts a rectangular structure. Specifically, the upper side wall of the shell 1 is provided with a slag discharge port 13, and the lower surface of the upper side wall of the shell 1 is provided with a material discharge plate 14. One end of the material discharge plate 14 is located below the slag discharge port 13, and the other end is located on the lower surface of the upper side wall of the shell 1.

[0065] like Figure 1 As shown, the shell 1 is provided with a slag discharge chamber 11, thereby providing installation space for the components of this device.

[0066] Among them, such as Figures 1-3As shown, the shell 1 is provided with openings 12 along the direction of slag conveying. Specifically, the lower side of the opposite two side walls of the shell 1 is provided with openings 12 that are adapted to the belt conveyor 3. The body of the belt conveyor 3 passes horizontally through the openings 12 on the two side walls of the shell 1 and the slag discharge chamber 11 inside the shell 1 along the direction of slag conveying, so as to ensure that the belt conveyor 3 conveys the slag that falls into the slag discharge chamber 11 of the shell 1 and does not fall outside the shell 1.

[0067] The belt conveyor 3 is provided with a support platform 20 on its lower side, and the housing 1 is provided on the upper surface of the support platform 20. Multiple columns 201 are provided between the belt conveyor 3 and the upper surface of the support platform 20 to support the belt conveyor 3. The belt conveyor 3 is existing technology and will not be described in detail.

[0068] In this embodiment, a plurality of support columns 202 are provided on the lower side of the support platform 20.

[0069] like Figure 1 As shown, the shell 1 is provided with multiple baffles 2. For ease of description, in this embodiment, three baffles 2 are used. The three baffles 2 are arranged at intervals in the vertical direction, and one end of each of the three baffles 2 is respectively set on two opposite side wall surfaces of the shell 1 with openings 12. Specifically, the three baffles 2 are set in the slag discharge chamber 11, and two adjacent baffles 2 are arranged symmetrically. One end of the uppermost baffle 2 is set on the lower side of the slag discharge port 13, and the other two side end surfaces of the baffle 2 are in contact with the other two opposite side wall surfaces of the inner side of the shell 1. The uppermost baffle 2 is close to the upper inner wall of the shell 1. The belt conveyor 3 is set on the lower side of the lowermost baffle 2, thereby ensuring that the slag slides down the baffle 2 to the belt conveyor 3.

[0070] In this embodiment, the distance between the end of the bottommost baffle 2 away from the side wall of the housing 1 and the belt of the conveyor belt is 5cm-10cm, thereby preventing large slag from falling into the belt located directly below the bottommost baffle 2.

[0071] The baffle 2 is inclined, and the end away from the side wall of the shell 1 is inclined downward. Specifically, the ends of two adjacent baffles 2 away from the side wall of the shell 1 are set vertically up and down, so as to ensure that the slag can fall stably from the upper baffle 2 to the lower baffle 2.

[0072] In this embodiment, as Figure 1 and Figure 5As shown, the upper surface of the baffle 2 is provided with a rotating shaft 4 perpendicular to the surface of the baffle 2. Multiple baffles 5 are arranged at intervals on the circumferential sidewall of the rotating shaft 4. The lower surface of the baffle 2 is provided with a rotating motor 6. One end of the rotating shaft 4 passes through the baffle 2 and is connected to the rotating motor 6. Specifically, the baffles 5 adopt a rectangular structure and are perpendicular to the surface of the baffle 2. The rotating motor 6 is coaxially arranged with the rotating shaft 4, and the rotating motor 6 drives the rotating shaft 4 to rotate, thereby driving the baffles 5 to rotate.

[0073] In this embodiment, when the slag falls onto the upper surface of the baffle 2, the rotating motor 6 drives the rotating shaft 4 to rotate, which in turn drives the baffle blades 5 to rotate. The baffle blades 5 are arranged at intervals along the circumference of the rotating shaft 4, so that when the slag falls between two baffle blades 5, the slag is pushed by the surface of one of the baffle blades 5, and then displaced on the upper surface of the baffle 2, and finally pushed to the other end of the baffle 2. Then, under the pushing force of the baffle blade 5 and the force of gravity, it falls along the inclined surface of the baffle blade 5 to the upper surface of the lower baffle 2, and is then pushed by the baffle blades 5 of the lower baffle 2, and finally falls onto the upper surface of the lowest baffle 2. Finally, the process of the slag falling onto the surface of the baffle 2 is repeated on the surface of the lowest baffle 2, and finally it enters the upper surface of the belt conveyor and is transported.

[0074] In this embodiment, multiple baffles 2 are arranged at intervals along the vertical direction and inclined downwards, thereby providing the power for the falling slag and reducing the impact of the slag falling onto the belt surface, thus avoiding significant damage to the belt and extending the service life of the belt conveyor 3. At the same time, the rotation of the rotating shaft 4 set on the baffle 2 and the rotation of the multiple baffles 2 provide power for the slag falling onto the surface of the baffle 2, allowing the slag to enter the belt conveyor 3 faster, resulting in a faster slag discharge speed and higher efficiency.

[0075] In some embodiments, such as Figure 1 , Figure 5 and Figure 6As shown, the baffle 2 adopts a stepped structure, and from top to bottom, it is provided with a first step 21 and a second step 22. The upper surface of the first step 21 is parallel to the upper surface of the second step 22. Specifically, the side of the first step 21 facing the rotation intersects with the upper surface of the second step 22, and the plane is set as the intersecting surface 23. The intersecting surface 23 is perpendicular to the upper surface of the second step 22. The rotating shaft 4 is set on the upper surface of the second step 22, and its axial direction is perpendicular to the upper surface of the second step 22. The rotating motor 6 is set on the lower surface of the second step 22. Thus, when the slag falls from the inclined upper surface of the first step 21 to the upper surface of the second step 22, the slag has a certain power due to the small height difference between the upper surfaces of the first step 21 and the second step 22. This allows the slag to move relatively quickly toward the rotating shaft 4 when it falls onto the upper surface of the second step 22, thereby avoiding the accumulation of a large amount of slag on the side of the second step 22 away from the rotating shaft 4, which would reduce the slag discharge speed.

[0076] Among them, such as Figures 5-7 As shown, the second step 22 is provided with a rotating hole, which is adapted to the rotating shaft 60, and the rotating shaft 4 is coaxial with the rotating hole.

[0077] It should be understood that the intersecting surface 23 is a plane and perpendicular to the upper surface of the second step 22. The trajectory of the rotating shaft 4 driving the baffle 5 to rotate is circular. Therefore, the distance between the end face of the baffle 5 away from the rotating shaft 4 and the inner wall of the housing 1 and the intersecting surface 23 will change with rotation. In order to ensure that the baffle 5 can rotate on the upper surface of the second step 22, the radial dimension of the baffle 5 along the rotating shaft 4 must be smaller than the distance between the end face of the baffle 5 and the nearest inner wall of the housing 1 or the intersecting surface 23. However, this method will result in the area of ​​the angle between the housing 1 and the intersecting surface 23 not being swept by the baffle 5, and there will be no subsequent slag as a power source to push the slag in this part. As a result, the slag falling to this part may accumulate in this part and cannot be discharged. Even if the slag eventually enters between the two baffles 5 along the upper surface of the second step 22, it will result in a longer time for this part of the slag to enter the belt conveyor 3, thereby reducing the slag discharge efficiency.

[0078] Therefore, in order to improve the above situation, in some embodiments, such as Figures 5-9As shown, the two end faces of the baffle 2 along the vertical direction of slag conveying are attached to the inner wall of the shell 1, and the symmetrical plane of the two side walls of the shell 1 along the direction of slag conveying passes through the first step 21, the intersecting surface 23 and the second step 22, and is symmetrical with respect to the symmetrical plane. The intersecting surface 23 is coaxially arranged with the rotating shaft 4. The end face of the baffle 5 away from the rotating shaft 4 is close to the intersecting surface 23 and the inner side of the shell 1, so that the shape of the intersecting surface 23 is adapted to the rotation trajectory of the baffle 5. Thus, when the slag is on the upper surface of the second step 22, it can be stably pushed to the other end of the second step 22 by the baffle 5. The slag falling into the first step 21 will also be pushed into the second platform by the action of the subsequent slag, so that the slag discharge efficiency is high.

[0079] In this embodiment, as Figures 5-9 As shown, a semi-circular groove 24 is formed on the lower surface of the intersecting surface 23 in a direction away from the rotating shaft 4, and the semi-circular groove 24, the intersecting surface 23 and the rotating shaft 4 are coaxially arranged, thereby preventing some slag from getting stuck between the baffle 5 and the intersecting surface 23.

[0080] In this embodiment, as Figure 1 as well as Figures 10-15 As shown, this device also includes multiple connecting bolts 8. A detachable brush component 7 is provided on the lower end face of the baffle 5. The lower end face of the brush component 7 abuts against the upper surface of the second step 22, and one end away from the rotating shaft 4 is located in the semi-circular groove 24. Specifically, the lower end of the baffle 5 is provided with a mounting groove 51. The brush component 7 includes a horizontal plate 71 and a vertical plate 72. The lower surface of the horizontal plate 71 is provided with several brush bristles. The vertical plate 72 is vertically arranged on the upper surface of the horizontal plate 71. The two ends of the horizontal plate 71 are symmetrical to the vertical plate 72. The vertical plate 72 is adapted to the mounting groove 51 and inserted into the mounting groove 51. Multiple first connecting holes 52 are provided on both sides of the mounting groove 51. The vertical plate 72 is provided with a second connecting hole 721 that passes through the plate wall. The multiple connecting bolts 8 are distributed... Do not pass through the first connecting hole 52 on one side of the multiple mounting grooves 51, the multiple second connecting holes 721, and the first connecting hole 52 on the other side of the multiple mounting grooves to connect with the nut. The end of the horizontal plate 71 away from the rotating shaft 4 is set in the semi-circular groove 24. If some of the slag enters the semi-circular groove 24 under the action of the baffle 5, it can also be swept away by the brush set in the semi-circular groove 24, thereby avoiding the accumulation of slag in the semi-circular groove 24. At the same time, since the vertical plate 72 is connected to the mounting groove by bolts, the distance between the horizontal plate 71 and the inner wall of the semi-circular groove 24 and the inner wall of the shell 1 can be controlled by replacing the brush part 7 with a horizontal plate 71 of different lengths, thereby adapting to construction conditions with different average particle sizes.

[0081] Furthermore, by replacing the brush part 7, brushes of different materials can be used to adapt to different types of slag and stone.

[0082] In some embodiments, the vertical plate 72 is smaller in the radial dimension of the rotating shaft 4 than the horizontal plate 71, and the vertical plate 72 is disposed at one end of the horizontal plate 71. The baffle 5 is higher than the upper surface of the first step 21, thereby enabling the baffle 5 to rotate stably and ensuring that some of the slag will not fall directly onto the lower baffle 2 from the rotating shaft 4 and the upper side of the baffle 5.

[0083] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the end of the second step 22 away from the first step 21 is provided with an inclined end 25. The inclined end 25 is inclined, which makes it easier for the slag to fall. Specifically, the inclined end 25 is set on one side of the rotating shaft 4. When the baffle 5 rotates to the upper side of the inclined end 25, part of the brush of the brush 7 is located on the upper side of the inclined end 25 and does not abut against the inclined end 25. As a result, when the slag is pushed to the end of the second step 22 away from the first step 21, due to the setting of the inclined end 25, the slag slides down the inclined end 25 to the lower baffle 2, which makes the slag enter the belt conveyor 3 more efficiently.

[0084] In some embodiments, such as Figure 10 As shown, a plurality of mounting and disassembly plate groups 9 are provided axially on the rotating shaft 4. The plurality of mounting and disassembly plate groups 9 are arranged sequentially at intervals along the circumference of the rotating shaft 4. For ease of description, in this embodiment, the number of mounting and disassembly plate groups 9 is four, and the four mounting and disassembly plate groups 9 are arranged sequentially at intervals along the circumference of the rotating shaft 4.

[0085] The assembly 9 includes two clamping plates 91 arranged axially along the rotation axis 4. The two clamping plates 91 are arranged opposite each other, and there is an installation space between the two clamping plates 91 that is adapted to the thickness of the baffle 5, so that the side ends of the multiple baffles 5 are respectively detachably arranged between the two clamping plates 91 of the assembly 9.

[0086] In this embodiment, as Figure 10 As shown, the device also includes multiple fixing bolts 10, and the baffle 5 is provided with multiple first fixing holes 53, which are arranged sequentially at intervals along the axial direction of the rotating shaft 4. The clamping plates 91 on both sides of the baffle 5 are provided with multiple corresponding second fixing holes 911. The baffle 5 and the clamping plates 91 on both sides are connected by multiple first fixing holes 53, multiple second fixing holes 911 and multiple fixing bolts 10, so that the baffle 5 is fixed on the rotating shaft 4 and can be disassembled. The baffle 5 can be replaced and maintained by disassembly, thereby avoiding the shutdown of the slag discharge process caused by the damage of the baffle 5.

[0087] In some embodiments, such as Figure 1 , Figure 5 , Figure 6 and Figure 8As shown, the upper surface of the first step 21 is provided with multiple shaft grooves 211. The axial direction of the shaft grooves 211 is perpendicular to the two end surfaces of the first step 21, and the shaft grooves 211 are spaced apart along the direction perpendicular to the intersecting surface 23. A rotating shaft 60 is provided in the shaft groove 211. Specifically, the multiple shaft grooves 211 are arranged sequentially and spaced apart along the forward direction of the slag on the upper surface of the first step 21, and a drive motor is provided at one end of the rotating shaft 60. The drive motor is located on the surface. The upper side of the shaft groove 211 has a slot. The rotating shaft 60 is coaxially arranged with the bearing, and the shaft of the rotating shaft 60 rotates until the bearing slot is higher than the upper surface of the first step 21. When the slag falls onto the upper surface of the first step 21, the rotating shaft 60 rotates under the drive of the drive motor, thereby providing power to the slag and enabling the slag to enter the second step 22 more quickly.

[0088] The rotational speed of the rotating shaft 60 and the rotational speed of the rotating shaft 4 can be set according to the actual situation of slag falling and being discharged.

[0089] In this embodiment, as Figure 6 , Figure 8 and Figure 16 As shown, anti-slag plates 50 are provided on both sides of the groove opening of the shaft groove 211. Specifically, the anti-slag plates 50 are arranged along the opening direction of the groove, and one end extends towards the center of the groove opening and is then placed close to the rotating shaft 60. The end of the anti-slag plate 50 facing the center of the groove opening has an arc surface that is adapted to the rotating shaft 60, thereby creating a gap between the anti-slag plate 50 and the rotating shaft 60, thus preventing a large amount of dust from entering the shaft groove 211.

[0090] The slag-proof plate 50 is connected to the first step 21 by multiple bolts, which makes the slag-proof plate 50 and the first step 21 detachably connected. This allows the slag at the trough to be cleaned by removing the slag-proof plate 50, making the cleaning process simpler.

[0091] In this embodiment, as Figures 1-2 As shown, a blower 30 is provided in the first step 21. Specifically, the air outlet of the blower 30 is located on the surface of the intersecting surface 23 and faces the semicircular groove 24 and the rotating shaft 4, so that the slag entering the semicircular groove 24 can be blown out between the two baffles 5, thereby preventing the slag from accumulating in the semicircular groove 24.

[0092] The device also includes a vacuum cleaner 40, one end of which is connected to the outer wall of the housing 1 through a pipe, thereby sucking in some of the dust blown up by the fan 30, thus preventing a large amount of dust from affecting the environment.
