Description

Technical Field

[0001] This invention belongs to the field of tunnel shotcrete technology, specifically a tunnel shotcrete-vibration-smoothing integrated surface protection mechanism. Background Technology

[0002] During tunnel construction, shotcreting the inner walls of the tunnel is essential. Uneven or broken surfaces can easily lead to collapses, water seepage, and other hazards if not addressed promptly, affecting subsequent operations. Shotcreting is a crucial process that involves using a high-pressure spray gun to evenly spray a properly mixed cement mortar or concrete onto the tunnel walls. This process directly impacts the safety of tunnel construction and its stable operation later on. After tunnel excavation, the surrounding rock is prone to loosening and spalling, and a dense protective layer is formed on the inner walls of the tunnel. Before construction, loose rocks and soil on the rock wall must be cleared, and the dry rock wall should be moistened with water to prevent the grout from drying out and cracking. When grouting, the angle of the spray gun and the spray pressure should be controlled to ensure that the grout adheres tightly to the rock wall. If necessary, the grout should be sprayed in layers to ensure that the protective layer thickness meets the standard. This process can not only seal the surrounding rock to isolate it from air and moisture and prevent the rock mass from weathering and crumbling, but also reinforce the loose surrounding rock and improve the overall bearing capacity. At the same time, it can level the inner wall to create conditions for subsequent support and pipeline laying, and lay a solid foundation for the safety and long-term stability of the tunnel construction.

[0003] In existing technologies, when spraying grout onto the inner wall of a tunnel, the grouting device simply sprays and covers it with high pressure. The surface usually cannot achieve a smooth state, which makes it easy for the grout to fall off due to gravity when spraying on the curved surface of the tunnel. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a surface protection mechanism integrating roadway spraying-vibration-smoothing, which solves the problem that existing sprayed surfaces often cannot achieve a smooth state, leading to the easy fall off due to gravity when spraying on the curved surface of the roadway.

A large arc plate is installed on the side of the arc-shaped protective frame close to the transmission gear. A limiting sleeve is installed on the middle side of the arc-shaped protective frame away from the first vibration frame through a bracket.

[0009] Preferably, two sets of fixing brackets are installed inside the second vibration frame near the limiting sleeve, and the fixing brackets are fixedly installed on one side inside the arc-shaped protective frame.

[0010] Preferably, the fixed bracket and the second vibration frame are elastically connected by a reset spring, and the second vibration frame has a movable groove in the middle, with the rotating shaft slidably disposed inside the movable groove.

[0011] Preferably, the limiting sleeve is equipped with a linkage swing assembly for internal rotation;

[0012] The linkage swing assembly includes a combined shaft, a swing sleeve is installed on the upper end of the combined shaft near the arc-shaped guard frame, and a telescopic rod is slidably arranged on the inner side of the swing sleeve. A rotating sleeve is installed on the end of the telescopic rod away from the swing sleeve, and an adjusting slide frame is rotatably arranged on the outer side of the rotating sleeve.

[0013] Preferably, the adjusting slide frame is slidably disposed inside the limiting slide frame, an arc-shaped frame is installed on the top of the adjusting slide frame, a shotcrete pipe is embedded inside the arc-shaped frame, a swing slide frame is installed on the side of the lower end of the combined shaft away from the arc-shaped guard frame, the linkage swing assembly includes a reducer, and the reducer is fixedly connected to the positioning shaft, a rotating disk is provided at the output end of the reducer, and an eccentric shaft is installed at the bottom of the rotating disk, and the swing slide frame is slidably disposed outside the eccentric shaft.

[0014] Preferably, a control box is installed on the top of the front of the movable base, and a shotcrete structure is installed on the top of the movable base, with the output end of the shotcrete structure fixedly connected to the shotcrete pipe.

[0015] Preferably, a connecting bracket is installed at the end of the arc-shaped gear frame away from the transmission gear, and the connecting bracket is fixedly installed on the front of the upper end of the limiting frame.

[0016] Preferably, the top of the movable seat is equipped with two sets of positioning frames, and a hydraulic cylinder is rotatably arranged on the inner side of the positioning frame. The output end of the hydraulic cylinder is equipped with a piston rod, and a push column is rotatably arranged on the inner side of the upper end of the piston rod. Welding plates are installed on the top of both ends of the push column, and the welding plates are fixedly installed on the bottom of the flip plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention utilizes a combination of a linkage vibration component and a hydraulic cylinder to control the vibration of the internal structure by controlling the swing of the arc-shaped protective frame. This vibration compacts the sprayed mortar. When the hydraulic cylinder pushes and adjusts, it causes the flipping plate to rotate along the limit frame. During this rotation, the arc-shaped protective frame rotates synchronously, and the transmission gear on one side of the arc-shaped protective frame rotates along the outer side of the arc-shaped gear frame. During this rotation, the rotating shaft synchronously drives each set of drive blocks to rotate. The drive blocks push the first and second vibration frames, which have arc-shaped steps, synchronously towards the moving seat. After continuous rotation, the drive blocks disengage from the arc-shaped steps. Under the strong push of the return spring, the first and second vibration frames quickly return to their original positions, patting the mortar inside. This reciprocating vibration compacts the mortar, effectively improving its adhesion to the wall and preventing it from falling off. Simultaneously, as the arc-shaped protective frame slides, the steel brush at the lower end remains in close contact with the wall, further compacting the mortar during the slide. Furthermore, the scraping action effectively improves the smoothness of the surface.

[0019] This invention utilizes a combination of linkage swing components and linkage vibration components to control the swaying adjustment of the shotcrete structure through linkage. The input end of the reducer is connected to a fixed limit frame, and a fixed shaft is installed on the upper end of the limit frame. During the rotation of the reducer, the internal structure is driven to rotate through the fixed shaft, thereby driving the rotating disk at the output end to rotate. During the rotation of the rotating disk, the eccentric shaft drives the swing slide frame to swing along the limit sleeve. During the swing, the combined shaft drives the swing sleeve and the telescopic rod to swing synchronously. During the swing, the telescopic rod extends and retracts along the inner side of the swing sleeve. The rotating sleeve at the end drives the adjusting slide frame to slide laterally back and forth along the limit slide frame. During the adjustment, mortar can be discharged through the shotcrete pipe and sprayed onto the surface of the tunnel to achieve a covering effect. Through linkage, the rapid swinging of the shotcrete structure can be synchronously controlled during the arc-shaped upward movement to assist in shotcreting, effectively ensuring the uniformity of shotcreting.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, the present invention provides a surface protection mechanism integrating roadway shotcreting-vibration-smoothing, including a movable base 100, two sets of limiting frames 103 are installed on the top of the movable base 100, and a linkage vibration component 001 is rotatably arranged on the outside of the limiting frame 103.

[0035] The linkage vibration assembly 001 includes an arc-shaped guard frame 200. Several sets of first vibration frames 301 are arranged on the inner side of the arc-shaped guard frame 200. A second vibration frame 303 is fixedly installed on one side of the first vibration frame 301. An arc-shaped step 302 is installed on the side of the first vibration frame 301 away from the moving seat 100. A rotating shaft 307 is rotatably arranged in the middle of the first vibration frame 301. Several sets of driving blocks 308 are arranged on the outer side of the rotating shaft 307, and the driving blocks 308 are rotatably arranged on the inner side of the first vibration frame 301. A ratchet and pawl module 309 is installed on the front of the rotating shaft 307. A transmission gear 300 is fixedly installed on the outer side of the ratchet and pawl module 309. The linkage vibration assembly 001 includes an arc-shaped gear frame 105. The transmission gear 300 is meshed on the outer side of the arc-shaped gear frame 105. A steel brush plate 210 is installed on one side of the lower end of the arc-shaped guard frame 200.

[0036] The above scheme employs the following: the movable seat 100 can move to provide support for the overall structure at the top; the limiting frame 103 can restrict the tilting plate 201, assisting in the tilting and adjustment of the upper structure; the arc-shaped guard frame 200 restricts the inner structure and can closely adhere to the arc surface at the upper end of the tunnel to achieve the effect of assisting in shotcreting; the first vibration frame 301 and the second vibration frame 303 are kept in a welded state, and the lateral movement inside the arc-shaped guard frame 200 can achieve the effect of vibration to compact the mortar; and the rotating shaft 307 can transmit kinetic energy. The cross-section of the drive block 308 is shaped like a magatama. When rotating, it can cooperate with the arc-shaped step structure 302 to realize the step structure. Under the action of the return spring 306, the second vibration frame 303 and the first vibration frame 301 can be pushed to quickly reset. The transmission gear 300 can mesh with the arc-shaped gear frame 105 to ensure that when the arc-shaped guard frame 200 is flipped, the transmission gear 300 can rotate along the arc-shaped gear frame 105. The gear ratio between the transmission gear 300 and the arc-shaped gear frame 105 is 1:10. The ratchet and pawl module 309 can restrict the rotation of the rotating shaft 307 in one direction.

[0037] like Figure 2 - Figure 5 As shown, a flip plate 201 is installed on one side of both ends of the arc-shaped guard frame 200. The end of the flip plate 201 away from the arc-shaped guard frame 200 is rotatably set on the outside of the limit frame 103. A positioning shaft 202 is installed on the inner side of the flip plate 201 near the limit frame 103. A limit slide frame 203 is fixedly installed on the top of the arc-shaped guard frame 200, and limit slide strips 204 are installed on both sides inside the limit slide frame 203.

[0038] Two sets of limiting grooves 205 are provided on the inner side of the arc-shaped guard frame 200 away from the transmission gear 300, and a torsion spring shaft 206 is rotatably arranged on the inner side of the limiting groove 205. A flipping arc plate 207 is fixedly installed between the two sets of torsion spring shafts 206. The flipping arc plate 207 is rotatably arranged on the inner side of the arc-shaped guard frame 200 away from the transmission gear 300. A large arc plate 208 is installed on the side of the arc-shaped guard frame 200 close to the transmission gear 300. A limiting sleeve 209 is installed on the side of the middle of the arc-shaped guard frame 200 away from the first vibration frame 301 through a bracket.

[0039] Two sets of fixing brackets 305 are installed inside the second vibration frame 303 on the side near the limiting sleeve 209. The fixing brackets 305 are fixedly installed on one side inside the arc-shaped protective frame 200.

[0040] The fixed bracket 305 and the second vibration frame 303 are elastically connected by a reset spring 306. The second vibration frame 303 has a movable groove 304 in the middle, and the rotating shaft 307 is slidably disposed inside the movable groove 304.

[0041] The above scheme is adopted: the flip plate 201 can assist the arc-shaped guard frame 200 in flipping adjustment. It can be combined with the limit frame 103 through the positioning shaft 202 to ensure the stability of rotation adjustment. The limit slide frame 203 can limit the inner adjustment slide frame 409 to ensure the stability of adjustment. The limit slide bar 204 can increase the sliding restriction. The limit groove 205 can limit the torsion spring shaft 206. The torsion spring shaft 206 can provide the flipping force for the flipping arc plate 207. After the flipping arc plate 207 is flipped, it can avoid affecting the normal movement of the device. The reset spring 306 inside the second vibration frame 303 can cooperate with the fixed bracket 305 to push the second vibration frame 303 to reset. Furthermore, a flexible structure is provided between the first vibration frame 301, the second vibration frame 303 and the arc-shaped guard frame 200 to close the gap of reciprocating movement to prevent mortar from entering the interior. The movable groove 304 can prevent the vibration frame from affecting the rotating shaft 307 when it moves.

[0042] like Figure 6 - Figure 7 As shown, the internal rotation of the limiting sleeve 209 is provided with a linkage swing assembly 002;

[0043] The linkage swing assembly 002 includes a combination shaft 405. A swing sleeve 406 is installed on the upper end of the combination shaft 405 near the arc-shaped guard frame 200. A telescopic rod 407 is slidably arranged on the inner side of the swing sleeve 406. A rotating sleeve 408 is installed on the end of the telescopic rod 407 away from the swing sleeve 406. An adjusting slide frame 409 is rotatably arranged on the outer side of the rotating sleeve 408.

[0044] The adjusting slide frame 409 is slidably disposed inside the limiting slide frame 203. An arc-shaped frame 410 is installed on the top of the adjusting slide frame 409. A shotcrete pipe 400 is embedded inside the arc-shaped frame 410. A swing slide frame 404 is installed on the side of the lower end of the combined shaft 405 away from the arc-shaped guard frame 200. The linkage swing assembly 002 includes a reducer 401, and the reducer 401 is fixedly connected to the positioning shaft 202. A rotating disk 402 is provided at the output end of the reducer 401, and an eccentric shaft 403 is installed at the bottom of the rotating disk 402. The swing slide frame 404 is slidably disposed outside the eccentric shaft 403.

[0045] Using the above scheme: the combined shaft 405 can rotate and adjust along the inner side of the limiting sleeve 209; the swing sleeve 406 can restrict the telescopic rod 407, allowing the position of the telescopic rod 407 to change during swinging; and the telescopic rod 407 can slide inside the swing sleeve 406, thereby interfering with and changing the position of the adjusting slide frame 409 inside the limiting slide frame 203; the arc frame 410 can restrict the shotcrete pipe 400, and the position of the shotcrete pipe 400 can be changed by sliding; and the reducer 4... The rotational power can be transmitted through the reducer 401. When the reducer 401 rotates on the upper end of the limit frame 103, it can drive the output end rotating disk 402 to rotate through the internal gear. The gear ratio of the reducer 401 is 1:10. The rotation of the rotating disk 402 will drive the eccentric shaft 403 to rotate. The rotation of the eccentric shaft 403 will push the swing slide frame 404 to swing along the combined shaft 405 for adjustment. By swinging, the adjustment slide frame 409 can be driven to perform lateral reciprocating sliding adjustment, thereby changing the spraying position.

[0046] like Figure 1 and Figure 8 As shown, a control box 101 is installed on the top of the front of the movable base 100, and a shotcrete structure 102 is installed on the top of the movable base 100. The output end of the shotcrete structure 102 is fixedly connected to the shotcrete pipe 400.

[0047] A connecting bracket 104 is installed at the end of the arc-shaped gear frame 105 away from the transmission gear 300. The connecting bracket 104 is fixedly installed on the front of the upper end of the limit frame 103.

[0048] Two sets of positioning frames 501 are installed on the top of the movable seat 100, and a hydraulic cylinder 502 is rotatably installed on the inner side of the positioning frame 501. A piston rod 500 is installed at the output end of the hydraulic cylinder 502, and a push column 503 is rotatably installed on the inner side of the upper end of the piston rod 500. Welding plates 504 are installed on the top of both ends of the push column 503, and the welding plates 504 are fixedly installed on the bottom of the flip plate 201.

[0049] Using the above scheme: the control box 101 can control the entire device; the spraying structure 102 can be used to transport and spray mortar; the connecting bracket 104 can connect the arc-shaped toothed frame 105 to the limiting frame 103; the positioning frame 501 can limit the hydraulic cylinder 502 and assist the hydraulic cylinder 502 in tilting and adjusting; the hydraulic cylinder 502, together with the piston rod 500, can control the extension of the pushing column 503; the welding plate 504 is used to connect the pushing column 503 to the tilting plate 201 to ensure the stability of the structure.

[0050] The working principle and usage process of this invention are as follows: The moving device of the moving seat 100 controls the large arc plate 208 to be closely attached to the inner wall of the tunnel. The piston rod 500 is extended by the hydraulic cylinder 502. During the extension process, the arc-shaped guard frame 200 and the flip plate 201 are flipped along the upper end of the limit frame 103. During the flipping process, the reducer 401 transmits the rotational force and drives the rotating disk 402 to rotate and adjust by a tenfold flipping. During the rotation process, the eccentric shaft 403 drives the swing slide frame 404 and the swing sleeve 406 to swing back and forth along the combined shaft 405. During the swinging process, the telescopic rod 407 can drive the adjusting slide frame 409 to slide back and forth laterally along the inner side of the limit slide frame 203. During the sliding process, the mortar is sprayed onto the inner wall of the tunnel by the spraying structure 102 and the spraying pipe 400.

[0051] As the arc-shaped protective frame 200 flips, the transmission gear 300 slides and rotates along the arc-shaped gear frame 105. During the rotation, the rotating shaft 307 and the drive block 308, together with the arc-shaped step 302, drive the first vibration frame 301 and the second vibration frame 303 to move towards the inside of the arc-shaped protective frame 200. As the rotation continues, the first vibration frame 301 and the second vibration frame 303 will quickly return to their original positions under the push of the return spring 306. By reciprocating, rapid vibration can be achieved to further compact the sprayed mortar, thereby increasing the compaction effect. Finally, during the sliding process, the steel brush plate 210 at the bottom will scrape the mortar to ensure flatness.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
