Description

Technical Field

[0001] The invention relates to the technical field of shotcrete reinforcement, in particular to a tunnel inner wall shotcrete reinforcement homogenization device. Background Art

[0002] As an important part of the modern transportation system, the safety and stability of tunnels are of great significance to ensuring smooth traffic and the safety of people's lives and property. With the acceleration of urbanization and the continuous advancement of infrastructure construction, the number and scale of tunnel construction continue to increase, and the requirements for the stability of tunnel structures are also getting higher and higher. The tunnel inner wall spraying reinforcement technology mainly uses high-pressure spraying of concrete or other composite materials to the tunnel wall to form a solid protective layer to enhance the stability of the tunnel structure. The slurry for reinforcement is mostly made of cement, bentonite, mortar and cellulose. Through a specific mix ratio and mixing process, a uniform slurry is formed, and then it is evenly applied to the tunnel wall by a sprayer with high pressure spraying.

[0003] In the tunnel inner wall shotcrete reinforcement technology, the mixing barrel is the key equipment for preparing shotcrete materials. The interior of the mixing barrel often produces attachments due to the long-term residence and solidification of the slurry. These attachments will not only affect the volume and mixing efficiency of the mixing barrel, but may also cause uneven mixing, thereby affecting the quality of the shotcrete material and the reinforcement effect of the tunnel. When the slurry solidifies in the mixing barrel, the attachments formed are often stubborn and difficult to remove by simple flushing or scraping, which not only increases the difficulty of cleaning, but also may damage the inner wall of the mixing barrel and shorten its service life. At the same time, during the drainage process, the slurry is easy to remain on the outer wall of the suction pipe. If it is not cleaned in time, these residues may gradually accumulate and cause blockage. Once the suction pipe is blocked, it will seriously affect the installation and use of subsequent suction equipment, and may even cause construction interruption, bringing great inconvenience and loss to the tunnel reinforcement project.

Two groups of second electric push rods 17 and third electric push rods 18 are symmetrically fixedly connected to the lower part of the fixed sleeve 16. The telescopic ends of the two third electric push rods 18 are fixedly connected to the load-bearing plate 56. The lower part of the load-bearing plate 56 is provided with multiple groups of knocking mechanisms 6 for impacting the attachments on the inner wall of the mixing barrel 23. The upper part of the load-bearing plate 56 is provided with a driving mechanism 5 for providing power to the knocking mechanism 6. The lower part of the load-bearing plate 56 is provided with a rotating mechanism 8. The knocking mechanism 6 is provided with a protective mechanism 7 outside for protection and for supporting the connection between the two groups of knocking mechanisms 6.

[0021] By adopting the above technical scheme, the homogenizing mechanism 2 can fully mix the grouting material on the inner wall of the tunnel, ensuring the uniformity and stability of the reinforcement material. The combination of the slide rail 14 and the fixed sleeve 16, as well as the application of the second electric push rod 17 and the third electric push rod 18, can realize the movement of the knocking mechanism 6 in the lateral and longitudinal directions. The driving mechanism 5 provides stable power for the knocking mechanism 6 to ensure the continuity and consistency of the knocking action.

[0024] Please refer to Figure 3 - Figure 7 As shown in, the homogenizing mechanism 2 includes a motor box 21 fixedly connected to the outer side wall of the stirring barrel 23. A first motor 22 is fixedly connected inside the motor box 21. A center plate 231 is fixedly connected to the upper end of the stirring barrel 23. An outer support frame 211 is fixedly connected to the inner side wall of the stirring barrel 23 below the center plate 231, and the outer support frame 211 penetrates to the outside of the stirring barrel 23 and communicates with the inside of the motor box 21. The inner bottom end of the stirring barrel 23 is connected by a bearing with a liquid suction core tube 26 for pumping out the slurry, and the end of the liquid suction core tube 26 extends above the center plate 231. A suction port 27 for the slurry to enter is opened in the lower part of the liquid suction core tube 26.

A toothed ring 24 is fixedly connected to the outer circumferential wall of the stirring barrel 23. Positioning plates 233 are symmetrically installed on the outer wall of the stirring barrel 23. Positioning holes 232 for positioning are opened on both the stirring barrel 23 and the positioning plates 233. The positioning holes 232 on the positioning plates 233 are inserted and matched with the positioning holes 232 on the stirring barrel 23 through positioning pins 234. A rotating rod 235 is fixedly connected to the side of the positioning plate 233 away from the stirring barrel 23. The end of the rotating rod 235 is rotatably sleeved on the U-shaped seat 11, and one of the rotating rods 235 extends to the outer side wall of the U-shaped seat 11. A third straight gear 35 is fixedly connected to the extending end of the rotating rod 235 extending to the outer side wall of the U-shaped seat 11.

[0025] By adopting the above technical solution, the first motor 22 transmits power to the stirring rod 25 through the first synchronous wheel 221 and the first synchronous belt 222, so that the stirring rod 25 and the stirring blade 28 rotate efficiently inside the stirring barrel 23, ensuring that the slurry is fully and evenly mixed in the stirring barrel 23, thereby improving the quality and stability of the spraying reinforcement material. The liquid extraction core tube 26 not only effectively extracts the slurry at the bottom of the stirring barrel 23 through the suction port 27 to realize the circulation of the slurry, but also further enhances the stirring effect through the design of rotating the stirring rod 25 on the liquid extraction core tube 26, which not only improves the mixing uniformity of the slurry, but also promotes the discharge of bubbles inside the slurry, reduces the bubble problem during the spraying process, and improves the density and strength of the reinforcement layer. Through the combination of the positioning plate 233, the positioning hole 232 and the positioning pin 234, the mixing barrel 23 is flexibly positioned on the U-shaped seat 11, which not only ensures the stability of the mixing barrel 23 during the operation, but also facilitates the operator to adjust the position of the mixing barrel 23 according to actual needs to adapt to different construction scenes.

[0026] See also Figure 8 and Fig. 9 The adjusting component 3 includes a second motor 31 fixedly connected to the top of the inner wall of the U-shaped seat 11, a spline shaft 32 is fixedly connected to the output end of the second motor 31, a second spur gear 34 meshing with the gear ring 24 is slidably sleeved on the spline shaft 32, the inner wall of the U-shaped seat 11 is located below the second motor 31 and is fixedly connected to a first gear seat 33, the inner top end of the first gear seat 33 is rotatably connected to the first bevel gear 331, the inner side wall of the first gear seat 33 is rotatably connected to the second bevel gear 332 meshing with the first bevel gear 331, the second bevel gear 332 is rotatably installed on the U-shaped seat 11 through a fixed shaft 333, one end of the fixed shaft 333 away from the second bevel gear 332 passes through the U-shaped seat 11 and is fixedly connected to the first spur gear 334, and the first spur gear 334 meshes with the third spur gear 35 for transmission.

[0027] By adopting the above technical solution, the adjustment component 3 uses the second motor 31 as the power source, and realizes meshing transmission with the gear ring 24 through the spline shaft 32 and the second spur gear 34 sliding sleeve connection, so as to accurately control the rotation of the mixing barrel 23, which not only improves the efficiency and stability of the transmission, but also ensures the precise positioning of the mixing barrel 23 during the rotation process. The meshing transmission of the first bevel gear 331 and the second bevel gear 332, and the meshing of the first spur gear 334 and the third spur gear 35 on the fixed shaft 333 form a stable and efficient transmission chain. Since the third spur gear 35 is fixedly connected to the rotating rod 235, when the first spur gear 334 and the third spur gear 35 are meshed, the rotation of the rotating rod 235 can be driven, and the rotating rod 235 is connected to the positioning plate 233, wherein the positioning plate 233 is rotatably sleeved with the mixing barrel 23 ( Figure 6Therefore, when the rotating rod 235 rotates, it can drive the mixing barrel 23 to adjust the angle, thereby facilitating the removal of the material knocked out from the inside.

[0029] By adopting the above technical scheme, the pressing mechanism 4 realizes fine regulation of the meshing transmission of the second spur gear 34 and the gear ring 24 through the telescopic function of the hydraulic push rod 41. The telescopic end of the hydraulic push rod 41 is fixedly connected to the clamping plate 42, and the clamping plate 42 is rotatably sleeved on the outer wall of the limiting sleeve 43, ensuring the stability of the second spur gear 34 during the transmission process.

The second spur gear 34 is driven to separate from the gear ring 24 by means of the telescopic property of the hydraulic push rod 41. At this time, the upper chuck 44 and the lower chuck 45 are meshed, driving the first bevel gear 331 and the second bevel gear 332 to mesh and transmit. At this time, the first spur gear 334 and the third spur gear 35 drive the mixing barrel 23 to rotate through the rotating rod 235. At this time, the mixing barrel 23 is tilted to remove the residue inside it.

One end of the bearing rod 632 away from the eccentric bearing 63 and the fourth bevel gear 572 are coaxially fixedly connected with a second synchronous wheel 58. The two second synchronous wheels 58 are connected by a second synchronous belt 59. The second synchronous wheel 58 coaxially and fixedly connected to the fourth bevel gear 572 is located on the outer wall of the second gear seat 57.

[0033] By adopting the above technical scheme, the knocking mechanism 6 realizes efficient knocking and homogenizing of the inner wall of the mixing barrel 23 through the ingenious combination of the eccentric bearing 63 and the bearing rod 632, and the impact mechanism of the impact rod 66 and the piston 653. The impact shovel head 67 further enhances the knocking force, making the knocking deeper, and effectively avoiding the problem of adhesion caused by solidification caused by slurry accumulation. The knocking mechanism 6 realizes synchronous rotation with the fourth bevel gear 572 through the transmission mechanism of the second synchronous wheel 58 and the second synchronous belt 59. The eccentric bearing 63 is slidably connected with the bearing sleeve 631, so that the bearing sleeve 631 can swing and the knocking action is smoother. The large cylinder sleeve 64 is slidably connected with the small cylinder sleeve 65, and the reset spring 661 assists in reset, so that the knocking mechanism 6 maintains stability and continuity during the knocking process. In addition, the one-way air intake valve 651 provides the necessary air pressure support for the impact of the piston 653, thereby improving the knocking effect.

The ends of the two bearing rods 632 are arranged inside the protection cover 73 through bearings, and the ends of the two bearing rods 632 extending to the inner side of the protection cover 73 are fixedly sleeved with a third sprocket 74, and the two third sprockets 74 are connected by a second chain 75.

[0035] By adopting the above technical scheme, the protection mechanism 7 forms an all-round protection system by means of the protection frame 71 fixedly connected to the outer walls of the two shell bodies 61, and the ladder frame 72 and the protective cover 73 located between the two shell bodies 61. The protective cover 73 protects the bearing rod 632 and its related components, avoids damage caused by impact, friction, etc., and extends the service life of the equipment. The connection between the third sprocket 74 and the second chain 75 in the protection mechanism 7 realizes the synchronous rotation between the two bearing rods 632, which not only simplifies the transmission link and reduces energy loss, but also ensures the stability and continuity of the knocking mechanism 6 during the knocking process. The ladder frame 72 and the protective cover 73 are fixedly connected, and the transmission mechanism of the third sprocket 74 and the second chain 75 ensures that the knocking mechanism 6 will not deviate or loosen during the knocking process.

[0036] See also Fig.11 and Fig.12The rotary mechanism 8 includes a circular plate 81 rotatably sleeved on the lower part of the load-bearing plate 56, and a plurality of extension rods 82 are fixedly connected to the inner ring wall of the circular plate 81 in a ring array. The end of the drive shaft 52 extends to the bottom of the load-bearing plate 56, and the end of the extension rod 82 is fixedly connected to the extended end of the drive shaft 52. The outer wall of the circular plate 81 is fixedly connected to a support frame 83, and a limiting bolt 84 is threadedly sleeved on the support frame 83.

The scraper 85 contacts the outer wall of the liquid extraction core tube 26, and the end of the limiting bolt 84 is rotatably connected to the scraper 85.

[0037] By adopting the above technical scheme, the circular plate 81 is connected to the support frame 83 to provide a stable support platform for the scraper 85, ensuring the stability of the scraper 85 when scraping the residual slurry on the outer wall of the liquid extraction core tube 26. The end of the limit bolt 84 is rotatably connected to the scraper 85, realizing the sliding adjustment of the scraper 85 inside the support frame 83. The extension rod 82 is fixedly connected to the extended end of the drive shaft 52 to realize the rotation movement of the circular plate 81. The scraper 85 moves around the outer wall of the liquid extraction core tube 26 to scrape the solidified slurry.

[0038] See also Fig.10 and Fig.13 The small cylinder sleeve 65 and the sliding sleeve 652 extend into the protective cover 73 away from one end of the impact rod 66 . The telescopic end of the second electric push rod 17 is fixedly connected to the square steel 171 , and the end of the square steel 171 is fixedly connected to the upper part of the protective frame 71 .

[0039] By adopting the above technical solution, the telescopic end of the second electric push rod 17 drives the telescopic movement of the protective frame 71, and the protective frame 71 cooperates with the knocking mechanism 6 to drive the knocking mechanism 6 to move up and down. At the same time, the second electric push rod 17 and the third electric push rod 18 move synchronously, driving the knocking mechanism 6 and the driving mechanism 5 to move downward synchronously, avoiding the two being out of sync, resulting in pulling and causing damage to the equipment.

[0040] Working principle: The fixed sleeve 16 is driven to move on the slide rail 14 by the telescopic end of the first electric push rod 15. The lower end of the fixed sleeve 16 is provided with a driving mechanism 5 and a knocking mechanism 6. When the driving mechanism 5 and the knocking mechanism 6 are located at the center of the mixing barrel 23 and stop moving, the position of the stirring blade 28 is adjusted to ensure that there is no contact between the knocking mechanism 6 and the stirring blade 28. The second electric push rod 17 and the third electric push rod 18 are synchronously controlled to move downward, thereby driving the driving mechanism 5 and the knocking mechanism 6 to move downward. As the knocking mechanism 6 moves downward, the third motor 51 is started, and the third motor 51 drives the driving shaft 52 and the first sprocket 53 to rotate. A chain 55 drives the two second sprockets 54 to move synchronously, and drives the third bevel gear 571 and the fourth bevel gear 572 below the second sprocket 54 to rotate. The fourth bevel gear 572 drives the second synchronous wheel 58 to rotate, and drives the bearing rod 632 to rotate through the cooperation of the second synchronous belt 59 and the second synchronous wheel 58. When the bearing rod 632 rotates, the eccentric bearing 63 swings and drives the sliding sleeve 652 and the small cylinder sleeve 65 below to make linear motion. At this time, the piston 653 moves laterally inside the small cylinder sleeve 65 quickly, and the air pressure inside the small cylinder sleeve 65 changes, and compresses and pushes the piston 653 to impact the impact rod 66. The impact rod 66 impacts the end of the impact shovel head 67 after being impacted, and the impact shovel head 67 will reciprocate and continuously impact, and with the help of the reset spring 661, the impact rod 66 is quickly reset. As the telescopic end of the second electric push rod 17 continues to move downward, the impact shovel head 67 impacts the inner wall of the mixing barrel 23, and the attachments attached to the inner wall of the mixing barrel 23 are shaken off by the impact force. The knocking mechanism 6 is provided with multiple groups, and another group of knocking mechanisms 6 is driven to work through the third sprocket 74 and the second chain 75 to strengthen the impact work on the inner wall of the mixing barrel 23. At the same time, the second electric push rod 17 and the first The three electric push rods 18 work synchronously. When the second electric push rod 17 moves down, the third electric push rod 18 also moves down. However, before using the equipment, it is necessary to adjust the gap between the scraper 85 and the liquid extraction core tube 26 so that the scraper 85 contacts the liquid extraction core tube 26. When the driving end of the third motor 51 drives the driving shaft 52 to rotate, since the end of the extension rod 82 is fixedly connected to the outer wall of the driving shaft 52, the extension rod 82 drives the circular plate 81 to rotate, and the scraper 85 contacts the outer wall of the liquid extraction core tube 26. As the scraper 85 rotates and contacts the liquid extraction core tube 26, the hardened slurry attached to the outer wall of the liquid extraction core tube 26 is removed, thereby improving the suction efficiency. When the mixing barrel 23 is cleaned, the knocking mechanism 6 does not rotate, but the mixing barrel 23 needs to rotate. When the mixing barrel 23 rotates, the second motor 31 is started to drive the spline shaft 32 and the second spur gear 34 to rotate. The second spur gear 34 meshes with the gear ring 24 to rotate the mixing barrel 23. Therefore, the inner wall of the mixing barrel 23 is cleaned by the knocking mechanism 6. It should be noted that when the mixing barrel 23 rotates, the mixing barrel 23 does not rotate 360 ​​degrees, but each rotation angle does not exceed 90 degrees, and it is in a reciprocating state. The rotary work is realized by the back motion, and the knocking mechanism 6 and the stirring blade 28 do not collide. It is necessary to ensure that the stirring blade 28 and the center plate 231 do not affect the knocking mechanism 6 and ensure that they are in a non-contact state with the knocking mechanism 6. The impact of the impact shovel head 67 on the stirring barrel 23 causes the attachments on the inner wall of the stirring barrel 23 to fall off, and the second electric push rod 17 and the third electric push rod 18 are controlled to drive the driving mechanism 5 and the knocking mechanism 6 to reset, so that the positioning hole 232 on the positioning plate 233 and the positioning hole 232 on the outer wall of the stirring barrel 23 are mutually aligned. After alignment, the positioning pin 234 is inserted into the positioning hole 232, and the support seat 19 is removed from the U-shaped seat 11. Then, the telescopic end of the hydraulic push rod 41 is controlled to drive the clamping plate 42 and the limiting sleeve 43 to descend. Under the pressure of the clamping plate 42, the second spur gear 34 is no longer engaged with the gear ring 24, and the upper chuck 44 at the lower end of the second spur gear 34 is engaged with the lower chuck 45. At this time, the spline shaft 32 rotates through the upper chuck 44 and the lower chuck 45 to transfer kinetic energy to the first bevel gear 331 and the second bevel gear 332, so that the second bevel gear 332 drives the fixed shaft 333 and the first spur gear 334 to rotate. Since the first spur gear 334 is meshed with the third spur gear 35 for transmission, the third spur gear 35 drives the rotating rod 235 and the positioning plate 233 to rotate. With the help of the positioning pin 234, the mixing barrel 23 is rotated. At this time, the mixing barrel 23 is tilted, and the tilt angle of the mixing barrel 23 needs to be controlled according to the distance between the second spur gear 34 and the gear ring 24. Then the worker takes out the hard objects inside the mixing barrel 23 to avoid accumulation inside the mixing barrel 23.
