[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0027] Referring to Figures 1 to 5 As shown, the present invention provides an integrated device for roadway support and transportation, including a guide rail 1 fixed on the inner top wall of the roadway. A hoisting mechanism 2 and a cantilever mechanism 4 are sequentially arranged on the guide rail 1. A self-balancing mechanism 3 is connected below the hoisting mechanism 2. The self-balancing mechanism 3 includes a support frame, on which a suspension basket 312 and a balance adjustment component are arranged. The suspension basket 312 is used for loading materials, and the balance adjustment component is used for balancing the suspension basket 312. The cantilever mechanism 4 is arranged close to the heading empty roof area, and a support mechanism 5 is arranged on the cantilever mechanism 4. The support mechanism 5 is used for temporarily supporting the heading empty roof area.

[0028] In this embodiment, the guide rail 1 is fixed by a conventional bolt technology.

[0029] The provided suspension basket 312 can load materials. The balance adjustment component can perform dynamic adaptive balance adjustment as the weight of the loaded materials increases, thereby reducing the swing amplitude of the suspension basket 312 during hoisting and transfer, and thus ensuring the safety during the material transfer process. At the same time, to a certain extent, the service life of the guide rail 1 is extended. The cantilever mechanism 4 drives multiple support mechanisms 5 to the heading empty roof area, and the provided support mechanism 5 is used for temporarily supporting the heading empty roof area.

[0030] Through the "transport - support" integrated design, the present invention realizes multiple optimizations of safety, efficiency and economy, and is particularly suitable for roadway tunneling operations under complex geological conditions.

[0031] Furthermore, the support frame includes a hanging arm 304 and a cross beam 302 horizontally connected to the bottom end of the hanging arm 304. The balance adjustment assembly includes sprockets 303 rotatably connected to both ends of the cross beam 302. The two sprockets 303 are connected by a chain drive. A counterweight 301 is slidably connected to the cross beam 302. The chain is connected to the counterweight 301. A linkage assembly is provided at one end of the cross beam 302. The hanging basket 312 is linked with the counterweight 301 through the linkage assembly.

[0032] When the hanging basket 312 is loaded with materials, under the gravity of the materials, it drives the linkage assembly to work, drives the sprocket 303 to rotate through the linkage assembly, the chain drives the counterweight 301 to move on the cross beam 302, re - establishes a balance point, and thus realizes the balance adjustment of the hanging basket 312.

[0033] Furthermore, the linkage assembly includes a slide bar 307 slidably connected to the cross beam 302. The top end of the slide bar 307 is connected with a toothed plate 306. A gear 305 is connected to the rotating shaft of one sprocket 303. The gear 305 meshes with the toothed plate 306. The bottom end of the slide bar 307 is connected with a buffer member, and the buffer member is connected with the hanging basket 312.

[0034] The downward - moving hanging basket 312 compresses the buffer member and drives the slide bar 307 and the toothed plate 306 to move downward synchronously. Through the meshing transmission between the toothed plate 306 and the gear 305, it drives the sprocket 303 to rotate. The rotating sprocket 303 drives the chain to move, the chain drives the counterweight 301 to move on the cross beam 302, re - establishes a balance point according to the lever principle, and thus realizes the balance adjustment of the hanging basket 312.

[0035] Furthermore, the buffer member includes a bottom plate 311 connected to the bottom end of the cross beam 302. Two guide rods 309 are connected to the bottom plate 311. A pressure plate 308 is slidably connected between the two guide rods 309. The middle part of the top end of the pressure plate 308 is connected to the bottom end of the slide bar 307. A spring 310 is provided between the pressure plate 308 and the bottom plate 311. The bottom end of the spring 310 is fixed on the bottom plate 311, and the top end of the spring 310 abuts against the pressure plate 308. The hanging basket 312 is connected to the pressure plate 308 through a rope.

[0036] The downward - moving hanging basket 312 drives the pressure plate 308 to move on the sliding rod 307, and at the same time compresses the spring 310 for buffering. When more materials are placed in the hanging basket 312, the hanging basket 312 drives the pressure plate 308 to further compress the spring 310 downward, and drives the sliding rod 307 and the toothed plate 306 to move downward synchronously. Through the meshing transmission between the toothed plate 306 and the gear 305, the sprocket 303 is driven to rotate. The rotating sprocket 303 drives the chain to move, and the chain drives the counterweight 301 to move further on the cross - beam 302, re - establishing the balance point, and thus realizing the balance adjustment of the hanging basket 312.

[0037] Further, the hoisting mechanism 2 includes a bracket 204 slidably connected to the guide rail 1. The bracket 204 is of a U - shaped structure. Wheels 203 are rotatably connected to the opposite sides of the opening of the bracket 204. The wheels 203 are slidably limited on the guide rail 1. The rotating shaft of the wheels 203 is connected to the output end of the second hydraulic motor 202. A hoisting member is provided at the bottom end of the bracket 204, and the hoisting member is used to adjust the suspended height of the hanging basket 312.

[0038] The hoisting of the hanging basket 312 is realized by the hoisting member. The second hydraulic motor 202 drives the wheels 203 to rotate, and then drives the hanging basket 312 to move along the guide rail 1, realizing the transfer of materials, eliminating manual handling, reducing work - related injuries, and improving the support efficiency.

[0039] Further, the hoisting member includes two support plates 206 fixedly connected to the bottom end of the bracket 204. A winch 205 is rotatably connected between the two support plates 206. A first hydraulic motor 201 is installed on the support plate 206. The first hydraulic motor 201 is in transmission cooperation with the winch 205. The steel rope on the winch 205 is connected to the support frame.

[0040] The first hydraulic motor 201 drives the winch 205 to rotate through a gear set, realizing the winding of the steel rope, and thus realizing the hoisting of the hanging basket 312.

[0041] Further, the cantilever mechanism 4 includes a traveling trolley 402 moving on the guide rail 1. The bottom end of the traveling trolley 402 is hinged with a support plate 401, and a hydraulic rod 403 is hinged between the traveling trolley 402 and the support plate 401. A triangular structure is formed among the traveling trolley 402, the support plate 401, and the hydraulic rod 403.

[0042] In this embodiment, the traveling structure of the traveling trolley 402 is the same as that of the hoisting mechanism 2, which will not be elaborated here.

[0043] By setting the hydraulic rod 403 to form a triangular structure with the traveling trolley 402 and the support plate 401, the stability of the connection to the support plate 401 is improved.

[0044] Furthermore, a hydraulic support rod 404 is hinged to the middle of the bottom end of the pallet 401. The hydraulic support rod 404 extends and presses against the bottom surface of the roadway to support the pallet 401 and improve the stability of the pallet 401.

[0045] Furthermore, the support mechanism 5 includes a plurality of support umbrella parts arranged in sequence at equal intervals on the pallet 401. A driving part is arranged on the pallet 401, and the support umbrella parts are unfolded through the driving part.

[0046] The driving part is used to drive the synchronous opening of the plurality of support umbrella parts to achieve temporary support for the heading empty roof area.

[0047] Furthermore, the support umbrella part includes a lead screw 503 rotatably connected to the pallet 401. The top end of the lead screw 503 is rotatably connected to the middle of a top plate 508. Arc-shaped plates 505 are hinged to both ends of the top plate 508. A slider 504 is threadedly connected to the lead screw 503. One ends of connecting plates 507 are symmetrically hinged to both sides of the slider 504. The other ends of the connecting plates 507 are hinged to the ends of the arc-shaped plates 505 far from the top plate 508. Long waist holes are formed in the connecting plates 507. Limit blocks are slidably limited on the long waist holes. One ends of inclined brackets 506 are hinged to the limit blocks. The other ends of the inclined brackets 506 are hinged to the middle of the arc-shaped plates 505. Expansion rods 509 are arranged on the connecting plates 507, and the telescopic ends of the expansion rods 509 abut against the bottom ends of the inclined brackets 506.

[0048] By driving the lead screw 503 to rotate through the driving part, under the limitation of the connecting plate 507, the slider 504 moves upward along the lead screw 503 while being screwed with the rotating lead screw 503. At the same time, the slider 504 drives the connecting plate 507 to rotate, so that the arc-shaped plate 505 rotates upward and unfolds. At this time, the arc-shaped plate 505 presses against the inner top wall of the heading empty roof area to complete the temporary support.

[0049] Furthermore, the driving part includes a hydraulic motor three 510 installed on the pallet 401. The output end of the hydraulic motor three 510 is connected with a worm 501. A turbine 502 is fixedly sleeved on the lead screw 503, and the worm 501 meshes with the turbine 502.

[0050] The hydraulic motor three 510 drives the worm 501 to rotate, and the turbine 502 drives the turbine 502 and the lead screw 503 to rotate. Interlocking is realized through the transmission of the turbine 502 and the lead screw 503 to ensure the reliability of the temporary support.

[0051] The integrated roadway support and transportation device provided by the present invention has the following working principle: When in use, the walking trolley 402 drives the pallet 401 to the position directly below the unsupported roof area at the heading face, and fixes the pallet 401. Then, the hydraulic motor three 510 is started to drive the worm 501 to rotate. The worm gear 502 drives the worm gear 502 and the lead screw 503 to rotate. Under the limitation of the connecting plate 507, the slider 504 moves upward along the lead screw 503 while being screwed with the rotating lead screw 503. At the same time, the slider 504 drives the connecting plate 507 to rotate, causing the arc-shaped plate 505 to rotate upward and unfold. At this time, the arc-shaped plate 505 presses against the inner top wall of the unsupported roof area at the heading face to complete the temporary support. When it is necessary to transfer materials, the materials are placed in the hanging basket 312. The hanging basket 312 drives the pressure plate 308 to move on the sliding rod 307, and at the same time compresses the spring 310 for buffering. When more materials are placed in the hanging basket 312, the hanging basket 312 drives the pressure plate 308 to further compress the spring 310 and drives the sliding rod 307 and the toothed plate 306 to move downward synchronously. Through the meshing transmission between the toothed plate 306 and the gear 305, the sprocket 303 is driven to rotate. The rotating sprocket 303 drives the chain to move, and the chain drives the counterweight 301 to move further on the cross beam 302 to re-establish the balance point, thereby realizing the balance adjustment of the hanging basket 312. Subsequently, the hanging basket 312 is hoisted through the hoisting member. The hydraulic motor two 202 drives the wheel 203 to rotate, thereby driving the hanging basket 312 to move along the guide rail 1 to realize the transfer of materials, eliminating manual handling, reducing work-related injuries, and improving the support efficiency.
