Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a rotary slag removal device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this invention and does not constitute prior art.

[0003] In existing tunnel construction processes, open-face tunnel boring machines (TBMs) are often used in tunnel excavation in areas with high safety levels of surrounding rock. Therefore, there is no need for segment support to block the surrounding rock, and the rear of the shield will be in direct contact with the surrounding rock. However, when an open-face tunnel boring machine passes through some areas with poor quality rock, the surrounding rock at the rear of the shield is prone to breakage. The broken rock will accumulate at the bottom of the main beam, resulting in a large accumulation of rock debris.

[0004] Currently, manual methods are primarily used to remove accumulated debris from the bottom of the main beam. While some devices can also remove it, such as belt-driven debris removal devices that transport the debris, manual intervention is still required for collection. Bucket wheel debris removal devices can clean debris autonomously, but these must be fixed to an open-face rock tunnel boring machine, making it impossible to control their movement along the tunnel's direction. Furthermore, their fixed location occupies significant space, making deployment difficult in situations with limited space under the main beam. Belt-driven autonomous debris removal devices also exist, but these still require manual adjustment of belt tension and wheelbase, and cannot be adjusted independently for accumulated debris. These are the current challenges facing debris removal devices in tunnel construction technology.

[0005] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary slag removal device that solves the need in the field of tunnel construction technology to autonomously clean the slag accumulated at the bottom of the main beam of an open rock tunnel boring machine and autonomously adjust its own construction position, thereby significantly improving the working efficiency of the tunnel boring machine.

[0007] The above-mentioned objectives of this invention are mainly achieved by the following technical solutions:

[0008] This invention provides a rotary slag removal device, comprising:

[0009] The travel track has an inner channel for the slag discharge mechanism to pass through, and the outer surface of the travel track is provided with an annular slide rail;

[0010] Multiple slag cleaning mechanisms are spaced apart on the annular slide rail. Each slag cleaning mechanism has a traveling structure that can slide with the annular slide rail and a slag cleaning tool connected to the traveling structure. The slag cleaning tool is configured to transport slag located below the slag discharge mechanism to the slag discharge mechanism.

[0011] In one specific embodiment, the walking structure includes a rolling wheel assembly and at least one guide wheel assembly. The rolling wheel assembly is slidably connected to the annular slide rail, and the walking rail forms at least one guide ring plate. The guide wheel assembly is rotatably disposed on the guide ring plate.

[0012] There are two guide ring plates, which are respectively arranged on both sides of the travel track along the axial direction of the travel track.

[0013] The guide wheel assembly includes an inner wheel assembly and an outer wheel assembly arranged opposite to each other. The outer wheel assembly is rolled on the outer surface of the guide ring plate, and the inner wheel assembly is rolled on the inner surface of the guide ring plate.

[0014] The rolling wheel assembly includes a driving roller and a driven roller that mesh with each other. The guide wheel assembly has a transition structure and is connected to the transition structure. The driven roller is connected to the transition structure via a gear shaft and can slide on the annular slide rail under the drive of the driving roller.

[0015] The walking structure also includes a walking motor, the output shaft of which is connected to the drive gear.

[0016] The travel track is equipped with a circular pantograph, and the travel motor is electrically connected to the circular pantograph via a cable.

[0017] In one specific embodiment, the adapter structure includes:

[0018] The adapter frame has two adapter plates arranged opposite each other, and a guide roller beam is connected to the same side of the two adapter plates. The guide wheel assembly is located between the two adapter plates.

[0019] Two mounting plates are located between the two adapter plates, and each mounting plate is connected to one adapter plate. Each mounting plate has a horizontal plate and a rib plate protruding from the horizontal plate. The guide wheel assembly is connected to the rib plate, and the gear shaft is connected to the horizontal plate.

[0020] In one specific embodiment, a movable structure is provided in the inner channel of the walking track, and the walking track is movably connected to the main beam through the movable structure, and the slag discharge mechanism is located between the two main beams.

[0021] In one specific embodiment, the slag cleaning tool includes a support shaft and a slag accumulation groove connected together. The support shaft is connected to the walking structure. The groove openings of the slag accumulation grooves of the plurality of slag cleaning tools face the same direction and are in the same sliding direction as the slag cleaning mechanism on the annular slide rail.

[0022] Compared with the prior art, the technical solution of the present invention has the following characteristics and advantages:

[0023] 1. This invention can continuously clean the slag and rocks at the bottom of the tunnel by rotating the slag cleaning mechanism on the travel track, and autonomously send the slag and rocks to the belt conveyor for transport. At the same time, the travel track can also move autonomously on the main beam of the shield machine through the translation mechanism. It is suitable for cleaning slag and rocks in different front and rear positions, has greater initiative, and can achieve complete cleaning without human intervention.

[0024] 2. This invention can set up multiple slag removal mechanisms to deploy multiple units in areas requiring high-density operations, and adjust the operating efficiency according to needs. At the same time, during non-working hours, multiple slag removal mechanisms can move to the upper part of the walking track to avoid gathering at the lower part of the walking track and affecting the normal passage of construction personnel. This structure can also simplify the layout conditions of the rotary slag removal device and solve the problem that the device occupies a huge space and has poor practicality due to consideration of slag removal effect.

[0045] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] like Figures 1 to 10 As shown, the present invention provides a rotary slag removal device, comprising:

[0049] The travel track 1 has an inner channel 14 through which the slag discharge mechanism 4 passes, and the outer surface of the travel track 1 is provided with an annular slide rail 11;

[0050] Multiple slag cleaning mechanisms 2 are spaced apart on the annular slide rail 11. Each slag cleaning mechanism 2 has a walking structure 21 that can slide with the annular slide rail 11 and a slag cleaning tool 22 connected to the walking structure 21. The slag cleaning tool 22 is configured to transport slag located below the slag discharge mechanism 4 to the slag discharge mechanism 4.

[0051] The rotary slag removal device of the present invention is mainly installed at the end of the main beam 5 of the tunnel boring machine. Through the cooperation of the traveling track 1 and the slag removal mechanism 2, the slag removal mechanism 2 can move autonomously on the annular slide rail 11. Simultaneously, by circulating on the annular traveling track 1, the slag removal mechanism 2 can remove the accumulated slag at the bottom of the main beam 5 and dump it into the slag discharge mechanism 4, which then transports it out of the tunnel, achieving autonomous slag removal. Furthermore, the installation of multiple slag removal mechanisms 2 allows for more efficient cleaning of the accumulated slag at the bottom of the tunnel. (See reference...) Figure 5 , Figure 6 As shown, by autonomously adjusting the positions of multiple slag removal mechanisms 2, they can be suspended at any position on the travel track 1, avoiding the problem of the slag removal mechanism 2 occupying the space at the bottom of the tunnel when the machine stops, thus enabling the slag removal mechanism 2 to have the characteristics of spatial integration.

[0052] Specifically, such as Figure 1 As shown, the traveling track 1 is generally circular and is movably connected to the main beam 5 via the movable structure 3. The slag discharge mechanism 4 is located between the two main beams 5; in a specific embodiment, as... Figure 4 As shown, the inner side of the traveling track 1 has a protrusion 15 perpendicular to the track surface. The protrusion 15 is also generally circular. Two moving structures 3 are symmetrically fixed on the protrusion 15, and both moving structures 3 can be movably connected to the main beam 5. Further, in this embodiment, the moving structure 3 includes a moving wheel 31 and a moving fixed block 32. The moving wheel 31 is set in the groove of the main beam 5. The rolling of the moving wheel 31 in the groove drives the traveling track 1 to move along the front and back direction of the main beam 5. Of course, in other embodiments, a slider or other means can also be used to drive the traveling track 1 to move. There is no limitation here. In a specific embodiment, each moving fixed block 32 is connected to two rotatable moving wheels 31. The moving fixed block 32 is fixedly connected to the protrusion 15 on the inner side of the traveling track 1. In other embodiments, the number of moving wheels 31 on each moving fixed block 32 can also be set to three or four. There is no limitation here. The rotary slag removal device of the present invention can move back and forth along the direction of the main beam 5 at the end of the shield machine main beam 5 through the moving structure 3, which expands the degree of freedom and further expands the range of autonomous slag removal.

[0053] In this invention, such as Figure 1 and Figure 2 As shown, the slag discharge mechanism 4 set between the two main beams 5 is a transmission belt with a guard plate 41. Of course, in other embodiments, the slag discharge mechanism 4 can also be a series of conveying buckets arranged at intervals, and the multiple conveying buckets are connected by a sprocket structure. There is no limitation on this.

[0054] like Figure 5 and Figure 6 As shown, in one specific embodiment, six slag-cleaning mechanisms 2 are provided on the outer surface of the walking track 1. Of course, in other embodiments, the number of slag-cleaning mechanisms 2 can be adjusted to four to twelve according to the needs of the slag-cleaning work, and there is no limitation thereto. Among them, the main component of the slag-cleaning mechanism 2 for cleaning accumulated slag is the slag-cleaning tool 22. In this invention, as shown... Figure 9 As shown, the slag removal tool 22 includes a support shaft 221 and a slag collection trough 222 connected together. One end of the support shaft 221 is connected to the walking structure 21, and the other end is connected to the slag collection trough 222. The slag collection trough 222 is a bucket-shaped container. Of course, in other embodiments, the slag collection trough 222 can also be replaced with a rock breaking tool, etc., depending on the construction environment and needs. There is no limitation on this. In this embodiment, the orientation of each slag collection trough 222 is the same as the direction of movement of the slag removal mechanism 2 on the annular slide rail 11, so that the slag at the bottom of the tunnel can be scooped up by the slag removal tool 22 and transported to the slag discharge mechanism 4. By using multiple slag removal tools 22 arranged at intervals, the slag removal frequency can also be adjusted to achieve a rapid slag removal effect.

[0055] like Figure 9 , Figure 10As shown, according to one embodiment of the present invention, the walking structure 21 includes a rolling wheel set 211 and at least one guide wheel set 212. The rolling wheel set 211 is slidably connected to the annular slide rail 11. The walking track 1 is formed with at least one guide ring plate 12. The guide wheel set 212 is slidably disposed on the guide ring plate 12.

[0056] The movement of the slag cleaning mechanism 2 on the walking track 1 is mainly achieved by the driving of the rolling wheel group 211 and the limiting function of the guide wheel group 212, so that the slag cleaning mechanism 2 has the ability to walk on the circular track surface, and realizes the ability to clean the bottom slag and integrate the device space.

[0057] Specifically, the guide ring plate 12 is disposed on the side of the walking track 1 along the axial direction F of the walking track 1. The guide wheel assembly 212 has multiple wheel sets, which can roll against the inner and outer surfaces of the guide ring plate 12. The guide wheel assembly 212 is connected to the rolling wheel assembly 211, and the guide wheel assembly 212, the rolling wheel assembly 211, and the slag removal tool 22 on the walking structure 21 are connected to form a rigid structural body. The rolling wheel assembly 211, through cooperation with the annular slide rail 11, can drive the walking structure 21 to move freely on the walking track 1. In this embodiment, there are two guide ring plates 12, symmetrically disposed on the two sides of the walking track 1 along the axial direction F of the walking track 1, and the cross-section of the walking track 1 with two guide ring plates 12 and the boss 15 is generally T-shaped; wherein, the two guide wheel assemblies 212 are respectively disposed on the two guide ring plates 12. In other embodiments, the number of guide ring plates 12 and guide wheel assemblies 212 can also be set to one or three, without limitation; see details. Figure 10 As shown, in this embodiment, the outer surface of the walking track 1 is provided with a protruding groove, which is an annular slide rail 11. The rolling wheel assembly 211 moves the slag cleaning mechanism 2 on the walking track 1 by cooperating with the annular slide rail 11. In other embodiments, the groove of the annular slide rail 11 can also be set to be flush with the outer surface of the walking track 1.

[0058] In one specific embodiment, see Figures 9 to 10 As shown, the guide wheel assembly 212 includes an inner wheel assembly 2121 and an outer wheel assembly 2122 that are arranged opposite to each other. The outer wheel assembly 2122 is rolled on the outer surface of the guide ring plate 12, and the inner wheel assembly 2121 is rolled on the inner surface of the guide ring plate 12.

[0059] The slag cleaning mechanism 2, through the guide wheel set 212, can restrict the movement of the slag cleaning mechanism 2 in the axial direction F and radial direction D of the travel track 1. At the same time, the rolling wheel set 211 can avoid positional changes in the axial direction F and radial direction D of the travel track 1, so that the rolling wheel set 211 can maintain cooperation with the annular slide rail 11 and ensure the autonomous movement capability of the slag cleaning mechanism 2.

[0060] In this embodiment, the number of rollers in each inner wheel group 2121 and the number of rollers in each outer wheel group 2122 are both four. Along the axial direction F of the traveling track 1, the rollers are arranged in pairs in a row, that is, there are two rollers in each row, and the four rollers form two rows of wheel groups. The two rows of wheel groups are arranged side by side along the rolling direction of the rollers. In other embodiments, the number of rollers can also be set to six or eight, without limitation. The guide wheel group 212 has a transition structure 23, and the inner wheel group 2121 and the outer wheel group 2122 of the guide wheel group 212 are both connected to the transition structure 23. Specifically, in this embodiment, the traveling structure 21 has two sets of guide wheel groups 212, and each guide wheel group 212 is arranged on a corresponding guide ring plate 12. The four rollers of each inner wheel group 2121 roll against the inner surface of the guide ring plate 12, and the four rollers of each outer wheel group 2122 roll against the outer surface of the guide ring plate 12.

[0061] In one specific embodiment, see Figures 9 to 10 As shown, the rolling wheel assembly 211 includes a driving roller 2111 and a driven roller 2112 that mesh with each other. The driven roller 2112 is connected to the adapter structure 23 through a gear shaft 2113. The driven roller 2112 can slide on the annular slide rail 11 under the drive of the driving roller 2111.

[0062] By cooperating with the rolling wheel assembly 211 and the annular slide rail 11, the slag cleaning mechanism 2 can be driven to move autonomously on the walking track 1. At the same time, based on the operating efficiency of the rolling wheel assembly 211, the working efficiency of the slag cleaning mechanism 2 in cleaning accumulated slag can be improved.

[0063] Specifically, in this embodiment, please refer to the following: Figure 7 , Figure 8 As shown, the annular slide rail 11 is an annular pin rack, the driven roller 2112 is a pin gear, and the driven roller 2112 is set at a position that meshes with the annular slide rail 11 without causing tooth knocking through the gear shaft 2113. The driving roller 2111 is a gear and is set in the area that meshes with the driven roller 2112. Of course, in other embodiments, the driven roller 2112, the annular slide rail 11 and the driving roller 2111 can adopt other matching methods, such as toothed belt connection, etc., and there is no limitation on this.

[0064] Furthermore, in one specific embodiment, such as Figures 9 to 12 As shown, the adapter structure 23 includes:

[0065] The adapter frame has two adapter plates 232 arranged opposite to each other, and guide roller beams 233 are connected to the same side of the two adapter plates 232. The guide wheel assembly 212 is located between the two adapter plates 232.

[0066] Two mounting plates 231 are located between the two adapter plates 232, and each mounting plate 231 is connected to one adapter plate 232. The mounting plate 231 has a horizontal plate 2311 and a rib plate 2312 protruding from the horizontal plate 2311. The guide wheel assembly 212 is connected to the rib plate 2312, and the gear shaft 2113 is connected to the horizontal plate 2311.

[0067] The guide wheel assembly 212 and the rolling wheel assembly 211 of the walking structure 21 can be connected together through the adapter structure 23. The guide wheel assembly 212 can be installed through the mounting plate 231 and, through the adapter plate 232 and the guide roller 233, the guide wheel assembly 212 can abut against the inner and outer surfaces of the guide ring plate 12, which restricts the movement of the entire slag cleaning mechanism 2 in the axial direction F and radial direction D of the annular walking track 1, and prevents the slag cleaning mechanism 2 from falling or failing to engage.

[0068] Specific reference Figure 11 As shown, in this embodiment, the cross-section of the mounting plate 231 is generally "T" shaped. The horizontal plate 2311 has a rib 2312 protruding on one side. The rib 2312 is provided with two bearing holes 2313. In the rollers of the inner wheel assembly 2121 or the rollers of the outer wheel assembly 2122, every two rollers are rotatably fixed on the rib 2312 through the bearing holes 2313. In other embodiments, the number of bearing holes 2313 can be set according to the number of rollers in the inner wheel assembly 2121 and the number of rollers in the outer wheel assembly 2122, and there is no limitation thereto. The horizontal plate 2311 has a tube cavity 2316 perpendicular to the bottom edge of the rib 2312 that contacts the horizontal plate 2311. A gear shaft 2113 is inserted inside the transverse plate 2311, and a driven roller 2112 is rotatably mounted on the gear shaft 2113. The upper surface of the transverse plate 2311 has two mounting surfaces 2315 symmetrical to the column cavity 2316. Each mounting surface 2315 has four mounting holes 2314. In other embodiments, the number of mounting holes 2314 can be set to six or eight according to the fixed requirements, and there is no limitation thereto. The transverse plate 2311 is connected to the adapter plate 232 through bolts or other connecting parts passing through these mounting holes 2314. Specifically, in this embodiment, the transverse plate 2311 is connected to the two adapter plates 232 through the mounting holes 2314 on the two mounting surfaces 2315.

[0069] See also Figure 12As shown, two transfer plates 232 arranged in parallel at intervals and the connected guide rollers 233 together form a structure generally in the shape of a "C". The guide rollers 233 are connected to the same side of the two transfer plates 232. The through holes 2321 provided on the transfer plates 232 correspond to the mounting holes 2314 provided on the mounting surface 2315 one by one, for fixing the transfer plates 232 to the mounting surface 2315. Each mounting surface 2315 corresponds to a transfer plate 232; specifically in this embodiment, with reference to Figure 9 and Figure 10 shown, the mounting plates 231 where each inner wheel set 2121 is located and the mounting plates 231 where the corresponding outer wheel sets 2122 are located are fixedly connected by four transfer plates 232 and two guide rollers 233. In other embodiments, they can also be fixedly connected by two transfer plates 232 and one guide roller 233, which is not limited thereto; specifically in this embodiment, the transfer structures 23 on the two guide ring plates 12 are connected by a backing plate 24. Among them, the backing plate 24 is connected to the transfer plate 232 connected to the outer wheel set 2122. This enables the two sets of guide wheel sets 212 provided on the two guide ring plates 12 to be fixed to each other through the backing plate 24, so as to limit the movement of the slag cleaning mechanism 2 in the axial direction F of the traveling track 1 and avoid situations such as the meshing misalignment of the driven rollers 2112 and the annular slide rail 11; at the same time, the support shaft 221 of the slag cleaning tool 22 is connected to the backing plate 24.

[0070] According to an embodiment of the present invention, as Figure 9 and Figure 10 shown, the traveling structure 21 further includes a traveling motor 25, and the output shaft 251 of the traveling motor 25 is connected to the driving roller 2111.

[0071] Through the traveling motor 25, a power source can be provided for the slag cleaning mechanism 2 to drive the rolling wheel set 211 to move on the traveling track 1 and drive the slag cleaning mechanism 2 to move on the annular traveling track 1. Specifically in this embodiment, the traveling motor 25 is fixed to the backing plate 24 by a fixed block with a replaceable height. A driving roller 2111 is sleeved on the output shaft 251 of the traveling motor 25. The driving roller 2111 is a gear, and the driving roller 2111 drives the driven roller 2112 to rotate by meshing with the driven roller 2112.

[0072] Furthermore, with reference to Figures 7 to 9As shown, the outer surface of the traveling track 1 is provided with an annular pantograph 13 located next to the annular slide rail 11. The annular pantograph 13 is generally circular. The traveling motor 25 is electrically connected to the annular pantograph 13 via a cable 252. In this embodiment, the annular pantograph 13 has a groove on the side facing away from the annular slide rail 11. The cable 252 is electrically connected in the groove. The annular pantograph 13 can be connected to an external power source to provide power to the traveling motor 25 via the cable 252. The annular pantograph 13 can avoid the wiring problems involved when the slag cleaning mechanism 2 moves, making the device more streamlined.

[0073] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
