Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, and in particular to a temporary support device for roadways in mining engineering. Background Technology

[0002] Mining engineering involves extracting all natural mineral or rock resources buried underground that are available for human use. Minerals can be classified into categories such as metals, non-metals, and combustible organics. They are non-renewable resources. In order to ensure that mineral resources can be used by people, temporary support devices are needed for tunnels. When tunnels are supported by temporary support devices, artificial structures are often used to form a "cooperative bearing system" with the surrounding rock to improve the long-term stability of the tunnels.

[0003] The existing temporary support devices are directly in contact with the top of the roadway. When using masonry arch support, the temporary support devices may be stuck to the arch and cannot be removed. This is because most of the existing support devices only have a structure to lift and lower the support plate. If the support plate is lowered by only the lifting structure, the support plate may fall down along with the entire arch at the top, which will reduce the stability of the roadway. Utility Model Content

[0004] Therefore, it is necessary to provide a temporary support device for roadways in mining engineering, which addresses the problem that temporary support devices may be stuck to the arch and cannot be removed, and that the support plate may fall down along with the entire arch at the top if the support plate is lowered by a lifting structure.

[0005] A temporary support device for roadways in mining engineering, comprising:

[0006] The support mechanism includes a base, mounting blocks, and a lifting plate. Two sets of mounting blocks are disposed on the upper surface of the corresponding base, and the upper surface of the base is provided with two sets of lifting components for driving the lifting plate to rise and fall.

[0007] A detachable mechanism, comprising a detachable plate, a connecting plate, and a connecting threaded rod, wherein the connecting plate is fixedly disposed on both sides of the detachable plate, and the detachable plate is threadedly connected to the lifting plate via the connecting threaded rod;

[0008] The auxiliary mechanism includes a connecting block, an extension column, an auxiliary top plate, and a drive assembly that raises and lowers the auxiliary top plate to support the roadway. Two sets of extension columns are provided, and the two sets of extension columns are slidably disposed inside the connecting block. Auxiliary top plates are provided on both sides of the extension column.

[0009] In one embodiment, the drive assembly includes a drive gear, a driven gear, an auxiliary threaded rod, and a connecting post. Two sets of auxiliary threaded rods and connecting posts are provided. The drive gear and the driven gear are rotatably disposed inside the connecting block. The two sets of auxiliary threaded rods are respectively fixedly connected to the upper surfaces of the drive gear and the driven gear. The two sets of connecting posts are threaded onto the outer arc surfaces of the two sets of auxiliary threaded rods, and the two sets of connecting posts are fixedly connected to the corresponding extension posts.

[0010] In one embodiment, the drive assembly further includes a drive motor and a toothed belt. The drive motor is disposed on the lower surface of the connecting block, the output end of the drive motor is connected to the drive gear, and the toothed belt is meshed and sleeved on the outer arc surface of the drive gear and the driven gear.

[0011] In one embodiment, both sets of connecting posts have snap-fit ​​blocks on their outer arc surfaces. The snap-fit ​​blocks are convex blocks, and the connecting blocks have snap-fit ​​grooves inside that correspond to the connecting posts and snap-fit ​​blocks.

[0012] In one embodiment, both sets of lifting components include a lifting column, a limiting plate, a drive threaded rod, and a lifting motor. The lifting motor is fixedly mounted on the upper surface of the base, the drive threaded rod is keyed to the output end of the lifting motor, and the lifting column is threaded onto the outer arc surface of the drive threaded rod.

[0013] In one embodiment, the limiting plate is fixedly disposed on the lower surface of the corresponding lifting column, and the drive threaded rod is threaded through the corresponding limiting plate.

[0014] In one embodiment, the mounting block is fixedly mounted on the upper surface of the base by a support frame, and the lifting column is slidably mounted inside the corresponding mounting block by a limiting plate.

[0015] In one embodiment, the extension column and the auxiliary top plate are symmetrically arranged on both sides of the lifting plate, and the auxiliary top plate does not contact the detachable plate.

[0016] Beneficial effects

[0017] 1. When the detachable plate is stuck to the roadway, the aforementioned temporary support device drives the extension column to rise through the drive component, thereby driving the auxiliary top plate to support the roadway on both sides of the detachable plate. At this time, the lifting component drives the top plate to fall, thereby supporting the roadway while driving the detachable plate to fall, thus avoiding tearing off the entire arch body that reinforces both sides of the detachable plate when attempting to disassemble it.

[0018] 2. The aforementioned temporary support device uses connecting plates on both sides of the detachable plate. The connecting plates then extend the detachable plate to the upper surface of the lifting plate via extension columns. The lifting plate moves the detachable plate into contact with the roadway and provides support. If the detachable plate still cannot be removed after the auxiliary roof support is applied, it can be directly removed from the upper surface of the lifting plate. This avoids forced disassembly that could reduce the stability of the roadway and also prevents the entire device from being left in the roadway for an extended period, thus affecting mining operations.

Detailed Implementation

[0026] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-5 This invention describes a temporary support device for roadways used in mining engineering.

[0028] In one embodiment, a temporary support device for a mining tunnel includes: a support mechanism 100, which includes a base 101, mounting blocks 102, and a lifting plate 103. Two sets of mounting blocks 102 are disposed on the upper surface of the corresponding base 101. The upper surface of the base 101 is provided with two sets of lifting components for driving the lifting plate 103 to rise and fall. Each set of lifting components includes a lifting column 104, a limiting plate 105, a drive threaded rod 106, and a lifting motor 107. 7 is fixedly set on the upper surface of the base 101. The drive threaded rod 106 is keyed to the output end of the lifting motor 107. The lifting column 104 is threadedly sleeved on the outer arc surface of the drive threaded rod 106. The limiting plate 105 is fixedly set on the lower surface of the corresponding lifting column 104, and the drive threaded rod 106 is threaded through the corresponding limiting plate 105. The mounting block 102 is fixedly set on the upper surface of the base 101 through the support frame. The lifting column 104 is slidably set inside the corresponding mounting block 102 through the limiting plate 105.

[0029] In this embodiment, the surfaces of the two sets of bases 101 are provided with ground plugs to limit the overall positioning of the device. A lifting motor 107 is provided to drive the drive threaded rod 106 to rotate. The drive threaded rod 106 can drive the lifting column 104 and the limiting plate 105 to move up and down through the thread. The mounting block 102 has a groove inside that corresponds to the limiting plate 105. When the lifting column 104 and the limiting plate 105 move up and down, the limiting plate 105 will be stuck inside the mounting block 102 and move up and down, thereby limiting the lifting column 104. This ensures that when the drive threaded rod 106 rotates, the lifting column 104 will only move up and down, thus preventing the lifting column 104 from rotating with the drive threaded rod 106. The up and down movement of the lifting column 104 drives the lifting plate 103 to move up and down, thereby supporting the roadway by lifting the lifting plate 103.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the detachable mechanism 200 includes a detachable plate 201, a connecting plate 202, and a connecting threaded rod 203. The connecting plate 202 is fixedly disposed on both sides of the detachable plate 201, and the detachable plate 201 is threadedly connected to the lifting plate 103 through the connecting threaded rod 203. The extension column 302 and the auxiliary top plate 303 are symmetrically disposed on both sides of the lifting plate 103, and the auxiliary top plate 303 does not contact the detachable plate 201.

[0031] In this embodiment, by setting connecting plates 202 on both sides of the detachable plate 201, and then passing the connecting threaded rod 203 through the connecting plate 202 and the lifting plate 103, the detachable plate 201 is connected to the upper surface of the lifting plate 103, thereby avoiding direct contact between the entire device and the roadway. When the detachable plate 201 cannot be removed, the detachable plate 201 is removed directly to prevent the device from being left in the roadway and affecting construction.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary mechanism 300 includes a connecting block 301, an extension column 302, an auxiliary top plate 303, and a drive assembly for supporting the roadway by raising and lowering the auxiliary top plate 303. Two sets of extension columns 302 are provided, and the two sets of extension columns 302 are slidably disposed inside the connecting block 301. Auxiliary top plates 303 are provided on both sides of the extension column 302. The drive assembly includes a drive gear 304, a driven gear 307, an auxiliary threaded rod 308, and a connecting column 309. Two sets of auxiliary threaded rods 308 and connecting columns 309 are provided. The drive gear 304 and the driven gear 307 are rotatably disposed inside the connecting block 301. The two sets of auxiliary threaded rods 308 are respectively fixedly connected to the upper surfaces of the drive gear 304 and the driven gear 307. The two sets of connecting columns 309 are threadedly sleeved on the outer arc surfaces of the two sets of auxiliary threaded rods 308, and the two sets of connecting columns 309 are fixedly connected to the corresponding extension columns 302.

[0033] In this embodiment, the drive gear 304 and the auxiliary threaded rod 308 are supported by the connecting block 301, ensuring that the drive gear 304 and the driven gear 307 can rotate inside the connecting block 301. When the drive gear 304 and the driven gear 307 rotate, they will drive the auxiliary threaded rod 308 to rotate, thereby driving the connecting column 309 to rise and fall through the auxiliary threaded rod 308. In turn, the connecting column 309 drives the extension column 302 and the auxiliary top plate 303 to rise and fall through the connecting column 309. The auxiliary top plate 303 contacts the tunnels on both sides of the detachable plate 201, thereby supporting the tunnels while driving the detachable plate 201 to fall through the lifting assembly.

[0034] like Figure 4 and Figure 5As shown, the drive assembly also includes a drive motor 305 and a toothed belt 306. The drive motor 305 is disposed on the lower surface of the connecting block 301. The output end of the drive motor 305 is connected to the drive gear 304. The toothed belt 306 is meshed and sleeved on the outer arc surface of the drive gear 304 and the driven gear 307. Both sets of connecting posts 309 are provided with snap-fit ​​blocks 310 on their outer arc surfaces. The snap-fit ​​blocks 310 are convex blocks, and the connecting block 301 has snap-fit ​​grooves 311 inside that correspond to the connecting posts 309 and the snap-fit ​​blocks 310.

[0035] In this embodiment, the drive motor 305 is started to drive the drive gear 304 to rotate. The drive gear 304 drives the driven gear 307 to rotate through the toothed belt 306, thereby driving the auxiliary top plate 303 to move up and down through the auxiliary threaded rod 308. Furthermore, snap-fit ​​blocks 310 are provided on both sides of the connecting column 309, and the snap-fit ​​blocks 310 are configured as protrusions that move up and down along the snap-fit ​​groove 311. This ensures that when the auxiliary threaded rod 308 rotates, the connecting column 309 will only drive the auxiliary top plate 303 to rise and fall, and will not rotate with the auxiliary threaded rod 308.

[0036] Working principle: When the detachable plate 201 is stuck to the tunnel and cannot be directly removed, the drive motor 305 is started to drive the drive gear 304 to rotate. The drive gear 304 drives the driven gear 307 to rotate through the toothed belt 306, thereby driving the two sets of auxiliary threaded rods 308 to rotate synchronously. The two sets of auxiliary threaded rods 308 drive the connecting column 309 to move upward. The connecting column 309 drives the auxiliary top plate 303 to contact the tunnels on both sides of the detachable plate 201. The auxiliary top plate 303 moves the tunnels on both sides of the detachable mechanism 200. The auxiliary support is then used, and the lifting plate 103 is lowered by the lifting assembly to avoid the roadway stability being reduced due to forced disassembly. When the auxiliary top plate 303 supports the roadway, if the detachable plate 201 still cannot be removed, the lifting plate 103 and the connecting plate 202 are separated by rotating the connecting threaded rod 203, thereby separating the detachable plate 201 from the lifting plate 103. After leaving the detachable plate 201 at the top of the roadway, the entire support device is moved out of the roadway, thus avoiding the device being left in the roadway for a long time and affecting mining operations.

[0037] It should be noted that the lifting motor 107 and drive motor 305 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the lifting motor 107 and drive motor 305 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
