[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] like Figures 1 to 3 As shown, an embodiment of the present invention provides a support device, which includes an adjustment assembly 10, a first support assembly 20, and a second support assembly 30. The adjustment assembly 10 includes a first support plate 11, a second support plate 12, and an adjustment structure 13. The first support plate 11 and the second support plate 12 are arranged opposite each other. The adjustment structure 13 is arranged between the first support plate 11 and the second support plate 12 to adjust the distance between the first support plate 11 and the second support plate 12, and the adjustment structure 13 is capable of supporting the tunnel roof. The first support assembly 20 and the second support assembly 30 are respectively located on either side of the adjustment assembly 10, with the first support assembly 20 being arranged near the first support plate 11 and the second support assembly 30 being arranged near the second support plate 12. One end of the first support assembly 20 is detachably connected to the first support plate 11, and the other end of the first support assembly 20 is used to be placed on the tunnel floor. One end of the second support assembly 30 is detachably connected to the second support plate 12, and the other end of the second support assembly 30 is used to be placed on the tunnel floor. The first support assembly 20 and the second support assembly 30 cooperate to support the tunnel wall.

[0055] Using the technical solution of this application, the adjustment structure 13 is located between the first support plate 11 and the second support plate 12. The adjustment structure 13 can adjust the distance between the first support plate 11 and the second support plate 12, and the adjustment structure 13 can also support the roof of the tunnel. The first support assembly 20 and the second support assembly 30 cooperate to support the adjustment assembly 10, and the first support assembly 20 and the second support assembly 30 can also support the tunnel side. This arrangement allows the width of the support device to be adjusted through the adjustment structure 13, allowing the support device to adapt to tunnels of different specifications, improving the applicability of the support device and reducing the cost of tunnel support. The adjustment structure 13 not only adjusts the distance but also directly supports the tunnel roof. This means that while adjusting the adjustment assembly 10, the support strength of the roof is also enhanced. This design can effectively disperse the pressure on the roof, reduce the risk of collapse caused by excessive local pressure on the roof, and improve the safety of the tunnel. The first support assembly 20 and the second support assembly 30 are detachably connected to the first support plate 11 and the second support plate 12 respectively. This design makes the installation and disassembly process of the support device more convenient, reduces the complexity and time cost of replacing or adjusting the support device during mining operations, and also facilitates maintenance and inspection.

[0056] like Figure 3 As shown, the adjustment structure 13 includes a first adjustment member 131, a second adjustment member 132 and one or more third adjustment members 133. The third adjustment member 133 is arranged between the first adjustment member 131 and the second adjustment member 132. One side of the first adjustment member 131 is detachably connected to the first support plate 11, and the other side of the first adjustment member 131 is detachably connected to the adjacent third adjustment member 133. One side of the second adjustment member 132 is detachably connected to the second support plate 12, and the other side of the second adjustment member 132 is detachably connected to the adjacent third adjustment member 133. The number of third adjustment members 133 is adjustable. When the adjustment structure 13 has multiple third adjustment members 133, two adjacent third adjustment members 133 are detachably connected. The first adjustment member 131, the second adjustment member 132 and the third adjustment member 133 cooperate to support the tunnel roof.

[0057] This arrangement, by making the number of third adjustment members 133 adjustable, allows the adjustment structure 13 to be dynamically adjusted according to different application requirements or space dimensions. Users can increase or decrease the number of third adjustment members 133 as needed, allowing the entire adjustment structure 13 to adapt to different support lengths or widths, thereby improving its applicability and versatility in various scenarios.

[0058] Furthermore, the first, second, and third adjusting members 131, 132, and 133 are detachably connected, allowing for independent manufacturing, testing, and storage of each adjusting member. This significantly simplifies on-site installation and maintenance. This modular design eliminates the need for extensive modifications to the entire structure during installation or removal, allowing operators to focus on the adjusting members that require adjustment, saving time and labor.

[0059] Optionally, when the width of the lane is too small, the adjustment structure 13 may only include a first adjustment member 131 and a second adjustment member 132 , and the first adjustment member 131 and the second adjustment member 132 are detachably connected.

[0060] Furthermore, the first adjusting member 131 , the second adjusting member 132 and the third adjusting member 133 cooperate to support the tunnel roof. This arrangement can ensure the effect of supporting the tunnel.

[0061] Specifically, in the present application, the first adjusting member 131 , the second adjusting member 132 and the third adjusting member 133 are I-shaped structures.

[0062] The adjustment structure 13 further includes an adjustment rod 134 and a sleeve 135. The adjustment rod 134 is disposed on a side of the first support plate 11 near the second support plate 12. The adjustment rod 134 is provided with a plurality of adjustment holes 1341 spaced apart along the extension direction of the adjustment rod 134. The sleeve 135 is disposed on a side of the second support plate 12 near the first support plate 11. The sleeve 135 is provided with a plurality of connection holes 1351 spaced apart along the extension direction of the sleeve 135. The adjustment rod 134 is slidably disposed within the sleeve 135. The adjustment holes 1341 and the connection holes 1351 are detachably connected via fasteners 136.

[0063] With this arrangement, the multiple adjustment holes 1341 on the adjustment rod 134 cooperate with the multiple connection holes 1351 on the sleeve 135 to precisely adjust the distance between the first support plate 11 and the second support plate 12 according to the actual roadway width requirements. This design provides high-precision adjustment capabilities, adapting to subtle changes in the roadway and ensuring accurate roadway support. The slidable design of the adjustment rod 134 within the sleeve 135 not only ensures flexible adjustment but also forms a stable structure when connected, ensuring that the overall strength of the adjustment structure 13 is not weakened by adjustments. In addition, the fasteners 136 that secure the adjustment holes 1341 to the connection holes 1351 further enhance the stability of the adjustment structure 13 and prevent accidental loosening during use. The detachable connection between the adjustment holes 1341 and the connection holes 1351 via the fasteners 136 means that the adjustment process can be completed quickly. The operator simply needs to select the appropriate adjustment hole 1341 and connection hole 1351, then secure them with the fasteners 136. This eliminates the need for complex adjustment tools, simplifying the operation process and improving work efficiency.

[0064] Specifically, the fastener 136 is threadedly connected to the adjustment hole 1341 .

[0065] Furthermore, the first adjusting member 131 has a first side and a second side that are relatively arranged. The first side of the first adjusting member 131 has a plurality of first fixing blocks 1311, and the first fixing blocks 1311 are provided with first through holes. The second side of the first adjusting member 131 has a plurality of second fixing blocks 1312, and the second fixing blocks 1312 are provided with second through holes. The first side of the first adjusting member 131 abuts against the first support plate 11, and the first fixing blocks 1311 of the first adjusting member 131 are detachably connected to the first support plate 11.

[0066] The second adjusting member 132 has a first side and a second side that are arranged opposite to each other. The first side of the second adjusting member 132 has a plurality of third fixing blocks 1321, and the third fixing blocks 1321 are provided with third through holes. The second side of the second adjusting member 132 has a plurality of fourth fixing blocks 1322, and the fourth fixing blocks 1322 are provided with fourth through holes. The second side of the second adjusting member 132 abuts against the second support plate 12, and the fourth fixing block 1322 of the second adjusting member 132 is detachably connected to the second support plate 12.

[0067] The third adjusting member 133 has a first side and a second side that are arranged opposite to each other. The first side of the third adjusting member 133 has a plurality of fifth fixing blocks 1331, and the fifth fixing blocks 1331 are provided with a fifth through hole. The second side of the third adjusting member 133 has a plurality of sixth fixing blocks 1332, and the sixth fixing blocks 1332 are provided with a sixth through hole. The plurality of second fixing blocks 1312 of the first adjusting member 131 are arranged in a one-to-one correspondence with the plurality of fifth fixing blocks 1331 of the adjacent third adjusting member 133, and the second fixing blocks 1312 are arranged in a one-to-one correspondence with the corresponding fifth fixing blocks 1331 is detachably connected via a locking member 137, and the multiple third fixing blocks 1321 of the second adjusting member 132 are arranged in one-to-one correspondence with the multiple sixth fixing blocks 1332 of the adjacent third adjusting member 133. The third fixing block 1321 and the corresponding sixth fixing block 1332 are detachably connected via a locking member 137. When the adjustment structure 13 has multiple third adjusting members 133, the fifth fixing block 1331 of the third adjusting member 133 and the sixth fixing block 1332 of the adjacent third adjusting member 133 are detachably connected via a locking member 137.

[0068] Because the first, second, and third adjusting members 131, 132, and 133 are detachably connected via a fixed block and locking member 137, this arrangement allows the adjustment structure 13 to be quickly configured and adjusted according to actual site needs, improving its ability to cope with varying geological conditions and tunnel dimensions. The through-hole design in each fixed block, coupled with the locking member 137 for connection, not only ensures the stability of the various adjusting members but also ensures the reliability of the connections. This design effectively resists lateral and longitudinal pressure within the tunnel, prevents loose connections and structural failure, and enhances the stability and safety of the entire support device.

[0069] Optionally, the locking member 137 may be a bolt.

[0070] Optionally, when the width of the lane is too small, the adjustment structure 13 may only include the first adjustment member 131 and the second adjustment member 132 , and the second fixing block 1312 and the third fixing block 1321 are detachably connected via a locking member 137 .

[0071] Specifically, in the present application, two fixing blocks are provided on both the first side and the second side of the adjusting member.

[0072] A first positioning structure is provided between the first adjusting member 131 and the adjacent third adjusting member 133 to fix the relative position between the first adjusting member 131 and the adjacent third adjusting member 133 .

[0073] In this way, the first positioning structure can ensure that the connection between the first adjusting member 131 and the adjacent third adjusting member 133 is firm and accurately positioned, which directly improves the stability of the overall support device. During the support process, structural loosening or deformation caused by the relative movement between the first adjusting member 131 and the adjacent third adjusting member 133 is avoided, ensuring the reliability of the support effect. At the same time, the first positioning structure can ensure that the installation between the first adjusting member 131 and the adjacent third adjusting member 133 can be more precise. During the assembly process, the first positioning structure ensures that the first adjusting member 131 and the adjacent third adjusting member 133 can be accurately aligned according to the design requirements, which not only simplifies the installation process, but also avoids unstable support or decreased structural strength due to installation errors.

[0074] A second positioning structure is defined between the second adjusting member 132 and the adjacent third adjusting member 133 to fix the relative position between the second adjusting member 132 and the adjacent third adjusting member 133 .

[0075] The second positioning structure can ensure that the connection between the second adjusting member 132 and the adjacent third adjusting member 133 is firm and accurately positioned, which directly improves the stability of the overall support device. During the support process, structural loosening or deformation caused by the relative movement between the second adjusting member 132 and the adjacent third adjusting member 133 is avoided, ensuring the reliability of the support effect. At the same time, the second positioning structure can ensure that the installation between the second adjusting member 132 and the adjacent third adjusting member 133 can be more precise. During the assembly process, the second positioning structure ensures that the second adjusting member 132 and the adjacent third adjusting member 133 can be accurately aligned according to the design requirements, which not only simplifies the installation process, but also avoids unstable support or decreased structural strength due to installation errors.

[0076] A plurality of first fixing rods 1313 are provided on the second side of the first adjusting member 131 , a plurality of first fixing holes 1323 are provided on the first side of the second adjusting member 132 , a plurality of second fixing holes 1333 are provided on the first side of the third adjusting member 133 , and a plurality of second fixing rods 1334 are provided on the second side of the third adjusting member 133 .

[0077] The multiple first fixing rods 1313 of the first adjusting member 131 are arranged in a one-to-one correspondence with the multiple second fixing holes 1333 of the adjacent third adjusting member 133. The first fixing rods 1313 are inserted into the corresponding second fixing holes 1333, and the first fixing rods 1313 and the second fixing holes 1333 cooperate to form a first positioning structure. This arrangement, through the precise correspondence between the first fixing rods 1313 and the second fixing holes 1333, achieves stable positioning and a secure connection between the first adjusting member 131 and the adjacent third adjusting member 133. Furthermore, the structure is simple and easy to manufacture.

[0078] The multiple first fixing holes 1323 of the second adjusting member 132 are arranged in a one-to-one correspondence with the multiple second fixing rods 1334 of the adjacent third adjusting member 133. The second fixing rods 1334 are inserted into the corresponding first fixing holes 1323, and the second fixing rods 1334 and the first fixing holes 1323 cooperate to form a second positioning structure. This arrangement, through the precise correspondence between the first fixing holes 1323 and the second fixing rods 1334, achieves stable positioning and a secure connection between the second adjusting member 132 and the adjacent third adjusting member 133. Furthermore, the structure is simple and easy to manufacture.

[0079] When the adjustment structure 13 has multiple third adjustment members 133, the second fixing holes 1333 of the third adjustment members 133 are arranged in one-to-one correspondence with the second fixing rods 1334 of the adjacent third adjustment members 133, and the second fixing rods 1334 are passed through the corresponding second fixing holes 1333. The second fixing rods 1334 and the second fixing holes 1333 cooperate to form a third positioning structure, and the third positioning structure can fix the relative position between two adjacent third adjustment members 133.

[0080] The third positioning structure can ensure that the connection between two adjacent third adjustment members 133 is firm and accurately positioned, which directly improves the stability of the overall support device. During the support process, structural loosening or deformation caused by the relative movement between the two adjacent third adjustment members 133 is avoided, ensuring the reliability of the support effect. At the same time, the third positioning structure can ensure that the installation between the two adjacent third adjustment members 133 can be more precise. During the assembly process, the third positioning structure ensures that the two adjacent third adjustment members 133 can be accurately aligned according to the design requirements, which not only simplifies the installation process, but also avoids unstable support or reduced structural strength due to installation errors.

[0081] Furthermore, the precise corresponding connection between the second fixing rods 1334 and the second fixing holes 1333 achieves stable positioning and a firm connection between two adjacent third adjusting members 133. Furthermore, the structure is simple and easy to process.

[0082] Optionally, when the width of the lane is too small, the adjustment structure 13 may only include the first adjustment member 131 and the second adjustment member 132 , and the first fixing rod 1313 is inserted into the first fixing hole 1323 .

[0083] like Figure 1 and Figure 2 As shown, the first supporting assembly 20 includes a first base 21 , two first main lower ribs 221 , two first auxiliary lower ribs 222 , a first connecting plate 23 , two first main upper ribs 241 and two first auxiliary upper ribs 242 .

[0084] One end of the two first main lower ribs 221 is disposed on a side of the first base 21 close to the adjustment assembly 10 .

[0085] One end of the two first auxiliary lower ribs 222 is disposed on the other side of the first base 21 , and the first main lower rib 221 and the first auxiliary lower rib 222 are located below the adjustment assembly 10 .

[0086] The first connecting plate 23 is fixedly connected to the other ends of the two first main lower ribs 221 and the other ends of the two first auxiliary lower ribs 222 .

[0087] One end of the two first main upper ribs 241 is set on the first connecting plate 23, the two first main upper ribs 241 and the two first main lower ribs 221 are located on the same side of the first connecting plate 23, the other end of the two first main upper ribs 241 is fixedly connected to the first support plate 11, and the first main upper ribs 241 are bent.

[0088] One end of the two first auxiliary upper ribs 242 is set on the first connecting plate 23, the two first auxiliary upper ribs 242 and the two first auxiliary lower ribs 222 are located on the same side of the first connecting plate 23, the other end of the two first auxiliary upper ribs 242 is fixedly connected to the first support plate 11, and the first auxiliary upper ribs 242 are bent.

[0089] In the existing technology, during mining, most of the structures supporting the rocks have poor supporting strength and cannot cope with the mining tunnels that require strong supporting strength. The tunnel surrounding rock is prone to bending and deformation, and the supporting device needs to withstand tensile stress and compressive stress. If the support strength is not enough, it cannot protect the safety of personnel and there is a safety hazard.

[0090] In the present application, the first auxiliary lower reinforcement 222 and the first auxiliary upper reinforcement 242 are equivalent to steel strips, which are prone to bending deformation and can withstand tensile stress as well as compressive stress. When the first main lower reinforcement 221, the first auxiliary lower reinforcement 222, the first connecting plate 23, the first main upper reinforcement 241 and the first auxiliary upper reinforcement 242 work together, the first main lower reinforcement 221 and the first main upper reinforcement 241 mainly bear tensile stress, and at the same time provide a certain extrusion stress to the surrounding rock. The greater the bending deformation, the greater the extrusion stress provided to the surrounding rock by the adjustment structure 13, which is more conducive to the stability of the surrounding rock, thereby changing the tunnel surrounding rock from an unfavorable tensile stress state to a favorable compressive stress state, which can effectively improve the safety of the mine tunnel.

[0091] With such arrangement, since the supporting device will be squeezed during the deformation of the surrounding rock of the tunnel, the supporting device will be deformed, and the first main lower reinforcement 221 and the first main upper reinforcement 241 can withstand tensile stress.

[0092] In addition, anchor rods are installed on the surrounding rock of the tunnel to further ensure the stability of the tunnel.

[0093] like Figure 1 and Figure 2As shown, the second supporting assembly 30 includes a second base 31 , two second main lower ribs 321 , two second auxiliary lower ribs 322 , a second connecting plate 33 , two second main upper ribs 341 and two second auxiliary upper ribs 342 .

[0094] One end of the two second main lower ribs 321 is disposed on a side of the second base 31 close to the adjustment assembly 10 .

[0095] One end of the two second auxiliary lower ribs 322 is disposed on the other side of the second base 31 , and the second main lower rib 321 and the second auxiliary lower rib 322 are located below the adjustment assembly 10 .

[0096] The second connecting plate 33 is fixedly connected to the other ends of the two second main lower ribs 321 and the other ends of the two second auxiliary lower ribs 322 .

[0097] One end of the two second main upper ribs 341 is set on the second connecting plate 33, the two second main upper ribs 341 and the two second main lower ribs 321 are located on the same side of the second connecting plate 33, the other end of the two second main upper ribs 341 is fixedly connected to the second support plate 12, and the second main upper ribs 341 are bent.

[0098] One end of the two second auxiliary upper ribs 342 is set on the second connecting plate 33, the two second auxiliary upper ribs 342 and the two second auxiliary lower ribs 322 are located on the same side of the second connecting plate 33, the other end of the two second auxiliary upper ribs 342 is fixedly connected to the second support plate 12, and the second auxiliary upper ribs 342 are bent.

[0099] In the present application, the second auxiliary lower reinforcement 322 and the second auxiliary upper reinforcement 342 are equivalent to steel strips, which are prone to bending deformation and can withstand tensile stress as well as compressive stress. When the second main lower reinforcement 321, the second auxiliary lower reinforcement 322, the second connecting plate 33, the second main upper reinforcement 341 and the second auxiliary upper reinforcement 342 work together, the second main lower reinforcement 321 and the second main upper reinforcement 341 mainly bear tensile stress, and at the same time provide a certain extrusion stress to the surrounding rock. The greater the bending deformation, the greater the extrusion stress provided to the surrounding rock by the adjustment structure 13, which is more conducive to the stability of the surrounding rock, thereby changing the tunnel surrounding rock from an unfavorable tensile stress state to a favorable compressive stress state, which can effectively improve the safety of the mine tunnel.

[0100] With such arrangement, since the supporting device will be squeezed during the deformation of the surrounding rock of the tunnel, the supporting device will be deformed, and the second main lower reinforcement 321 and the second main upper reinforcement 341 can withstand the tensile stress.

[0101] like Figure 2 As shown, a first lower support plate 251 is provided between the two first main lower ribs 221 and the two first auxiliary lower ribs 222 , and a first upper support plate 252 is provided between the two first main upper ribs 241 and the two first auxiliary upper ribs 242 .

[0102] With this arrangement, the addition of the first lower support plate 251 and the first upper support plate 252 significantly enhances the stability of the first support assembly 20. The first lower support plate 251 laterally connects the two first main lower ribs 221 and the two first auxiliary lower ribs 222, while the first upper support plate 252 vertically connects the two first main upper ribs 241 and the two first auxiliary upper ribs 242, forming a more robust frame for the first support assembly 20 that can effectively resist lateral pressure and torsional forces, thereby improving the rigidity and stability of the first support assembly 20.

[0103] like Figure 1 As shown, a second lower supporting plate 351 is provided between the two second main lower ribs 321 and the two second auxiliary lower ribs 322 , and a second upper supporting plate 352 is provided between the two second main upper ribs 341 and the two second auxiliary upper ribs 342 .

[0104] With this arrangement, the addition of the second lower support plate 351 and the second upper support plate 352 significantly enhances the stability of the second support assembly 30. The second lower support plate 351 laterally connects the two second main lower ribs 321 and the two second auxiliary lower ribs 322, while the second upper support plate 352 vertically connects the two second main upper ribs 341 and the two second auxiliary upper ribs 342, forming a more rigid frame for the second support assembly 30 that can effectively resist lateral pressure and torsional forces, thereby improving the rigidity and stability of the second support assembly 30.

[0105] like Figure 1 As shown, a first lower reinforcing plate 261 is provided between the two first auxiliary lower ribs 222 , and a first upper reinforcing plate 262 is provided between the two first auxiliary upper ribs 242 .

[0106] With this arrangement, the use of the first lower reinforcing plate 261 significantly strengthens the rigid connection between the two first auxiliary lower ribs 222, while the use of the first upper reinforcing plate 262 significantly strengthens the rigid connection between the two first auxiliary upper ribs 242, reducing overall deformation that may occur when subjected to stress. This not only improves the structural stability of the first support assembly 20, but also better disperses and carries stress from different directions, ensuring that the first support assembly 20 remains stable even when subjected to complex pressures in mine tunnels.

[0107] like Figure 1 As shown, a second lower reinforcing plate 361 is provided between the two second auxiliary lower ribs 322 , and a second upper reinforcing plate 362 is provided between the two second auxiliary upper ribs 342 .

[0108] This arrangement significantly strengthens the rigid connection between the two second lower auxiliary ribs 322, while the second upper reinforcement plate 362 significantly strengthens the rigid connection between the two second upper auxiliary ribs 342, reducing overall deformation that may occur when subjected to stress. This not only improves the structural stability of the second support assembly 30 but also better distributes and carries stress from different directions, ensuring that the second support assembly 30 remains stable even when subjected to complex pressures in a mine tunnel.

[0109] In the present application, the first lower support plate 251 is fixedly connected to the first main lower rib 221 and the first auxiliary lower rib 222, and the first lower reinforcing plate 261 is fixedly connected to the first auxiliary lower rib 222 via a first sleeve 28. The second lower support plate 351 is fixedly connected to the second main lower rib 321 and the second auxiliary lower rib 322, and the second lower reinforcing plate 361 is fixedly connected to the second auxiliary lower rib 322 via a second sleeve 38.

[0110] Furthermore, the first supporting assembly 20 further includes two first main fixing blocks 271 and two first auxiliary fixing blocks 272 .

[0111] The two first main fixing blocks 271 are arranged in a one-to-one correspondence with the two first main lower ribs 221 . One end of the first main fixing block 271 is fixedly connected to the corresponding first main lower rib 221 , and the other end of the first main fixing block 271 is fixedly connected to the first connecting plate 23 .

[0112] The two first auxiliary fixing blocks 272 are arranged in one-to-one correspondence with the two first auxiliary lower ribs 222 . One end of the first auxiliary fixing block 272 is fixedly connected to the corresponding first auxiliary lower rib 222 , and the other end of the first auxiliary fixing block 272 is fixedly connected to the first connecting plate 23 .

[0113] This arrangement, by adding the first main fixing block 271 and the first auxiliary fixing block 272 between the first main lower rib 221 and the first auxiliary lower rib 222 and the first connecting plate 23, respectively, significantly increases the contact area and connection strength between the first main lower rib 221 and the first connecting plate 23, as well as between the first auxiliary lower rib 222 and the first connecting plate 23. This arrangement effectively disperses and absorbs loads transmitted from the roadway roof and side walls, reduces localized stress concentration in the first main lower rib 221 and the first auxiliary lower rib 222, and improves the structural stability and durability of the first support assembly 20.

[0114] The first main fixing block 271 and the first auxiliary fixing block 272 are removably connected to the first main lower rib 221, the first auxiliary lower rib 222, and the first connecting plate 23, simplifying on-site assembly and disassembly. Workers can quickly position and secure these components without complex alignment or special tools, greatly improving work efficiency, reducing installation time, and reducing the risk of loose connections due to improper operation.

[0115] Furthermore, the second supporting assembly 30 further includes two second main fixing blocks 371 and two second auxiliary fixing blocks 372 .

[0116] The two second main fixing blocks 371 are arranged in a one-to-one correspondence with the two second main lower ribs 321 . One end of the second main fixing block 371 is fixedly connected to the corresponding second main lower rib 321 , and the other end of the second main fixing block 371 is fixedly connected to the second connecting plate 33 .

[0117] The two second auxiliary fixing blocks 372 are arranged in a one-to-one correspondence with the two second auxiliary lower ribs 322 . One end of the second auxiliary fixing block 372 is fixedly connected to the corresponding second auxiliary lower rib 322 , and the other end of the second auxiliary fixing block 372 is fixedly connected to the second connecting plate 33 .

[0118] This arrangement, by adding the second main fixing block 371 and the second auxiliary fixing block 372 between the second main lower rib 321 and the second auxiliary lower rib 322 and the second connecting plate 33, respectively, significantly increases the contact area and connection strength between the second main lower rib 321 and the second connecting plate 33, as well as between the second auxiliary lower rib 322 and the second connecting plate 33. This arrangement effectively disperses and absorbs the loads transmitted by the roadway roof and side walls, reduces localized stress concentration on the second main lower rib 321 and the second auxiliary lower rib 322, and improves the structural stability and durability of the second support assembly 30.

[0119] The second main fixing block 371 and the second auxiliary fixing block 372 are removably connected to the second main lower rib 321, the second auxiliary lower rib 322, and the second connecting plate 33, simplifying on-site assembly and disassembly. Workers can quickly position and secure these components without complex alignment or special tools, greatly improving work efficiency, reducing installation time, and reducing the risk of loose connections due to improper operation.
