[0003] However, there are some problems in the actual working process of the existing tunnel construction grouting trolleys. For example, a fully automatic secondary lining grouting trolley with publication number CN110700858A can be easily set up, but in the actual working process, workers are still required to stand on the working platform at each grouting port to perform manual grouting, which has low work efficiency and high labor intensity. In the working process, a lining trolley layered material distribution device for hydraulic tunnel construction with publication number CN117365565B can be used through the layered lower grouting pipes and the upper grouting pipes. , realizing automatic layered pouring, but the connection of its pipelines is complicated and inconvenient to disassemble and install, which cannot ensure the convenience of subsequent disassembly and transportation of the grouting trolley; and it cannot stably pour the top layer of the formwork; and in the actual working process, it cannot perform on-site mixing and mixing of the required concrete according to the use requirements, load conditions and environmental factors of the tunnel, and it cannot conveniently adjust the flow rate of the concrete according to the actual situation.

[0016] Beneficial Effects

[0017] The grouting trolley for tunnel construction provided by the present invention has the following beneficial effects:

[0018] 1. Through the driving cooperation of the first hydraulic rod and the third hydraulic rod, the third connecting pipe can be driven to gradually connect with the first grouting pipe, the second grouting pipe and the fourth connecting pipe and the fifth connecting pipe on the third grouting pipe, thereby realizing efficient layered pouring of tunnel construction, without the need for flange connection of multiple pipes, and each pipe can be conveniently disassembled after the work is completed, ensuring the convenience of subsequent transportation; and by utilizing the meshing drive of the rack and the first gear, the third hydraulic rods on both sides can be driven to rotate upward at the same time through the rotating block on the rotating shaft, thereby driving the third connecting pipe to be conveniently connected with the embedded pipe, so that the pouring of the top layer of concrete can be completed conveniently and stably, increasing the diversity and practicality of the grouting trolley.

[0019] 2. Through the meshing drive of the worm and the worm wheel, under the joint guiding action of the first guide groove and the second guide groove, the blocks on each guide rod can be driven to move simultaneously, so that the size of the concrete conveying channel opening can be conveniently adjusted, and the precise control of the concrete conveying flow rate is achieved. By regulating the concrete conveying flow rate, an appropriate flow rate can be adopted, which is helpful to fill the concrete into every corner, avoid bubbles and gaps, and improve the compactness of the concrete, thereby effectively improving the workability of the concrete and the final engineering quality.

[0020] 3. Through the cooperation of the positioning rod and the clamping rod, the disassembly and installation of the multifunctional grouting assembly can be completed conveniently, thereby ensuring the convenience of the subsequent overall disassembly and assembly of the grouting trolley, and at the same time ensuring the convenience of the subsequent transportation of the grouting trolley.

[0021] 4. Through the rotation of the threaded rod, the rubber airbag can be conveniently inflated through the rubber piston, and the internal storage space of the adjusting groove can be conveniently and accurately adjusted in conjunction with the adjusting plate. Subsequently, under the meshing drive of the second gear and each third gear, the corresponding turntable can be driven to rotate simultaneously. At this time, the adjusting groove on the turntable is first aligned with the first material discharge groove on the first material guide plate, and then aligned with the second material discharge groove on the second material guide plate. Under the adjustment and discharge action of the four turntables, cement, aggregate, admixture and water can be accurately proportioned respectively, realizing on-site mixing of concrete, and then the strength grade, durability and fluidity of the concrete can be determined according to the use requirements, load conditions and environmental factors of the tunnel, further increasing the diversity and practicality of the grouting trolley.

[0022] 5. Through the continuous rotation of the sliding rod, the sliding groove on the sliding plate can be used to drive the reinforcing rod and the fixed frame to rotate at the same time. At the same time, during the rotation of the upper and lower fixed frames, the guide plate and the guide block can be driven to intermittently contact. At this time, under the guiding action of the guide plate and the guide block, the third spring can push the reinforcing rod and the fixed frame to perform automatic and stable up and down reciprocating motion during the rotation process. In conjunction with the first cutting blades, the second cutting blades and the mixing plate, efficient stirring and mixing of each raw material is achieved. In conjunction with the intermittent feeding of each raw material, the mixing rate can be further improved. At the same time, it avoids the problem of agglomeration caused by the one-time addition of a large amount of raw materials, which affects the mixing rate and mixing effect, and effectively improves the working efficiency of the grouting trolley.

[0058] Embodiment 3:

[0059] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0060] Specifically, when the grouting trolley for tunnel construction is used: first, the staff transports the cement, aggregate, admixture and water required for concrete preparation to the four storage tanks 1402 in the first processing box 1401 through the feed pipe 1403, and then the staff can rotate the threaded rod 1416 on the filter plate 1415 at the end of the gas storage frame 1414. Under the action of the threaded rotation of the threaded rod 1416, the rubber piston 1417 can be pushed to move stably inside the gas storage frame 1414. Under the action of the movement of the rubber piston 1417, The rubber airbag 1418 can be conveniently inflated through the air storage frame 1414, thereby driving the adjustment plate 1419 to stably move inside the adjustment slot 1413 on the turntable 1412. The internal material storage space of the adjustment slot 1413 can be conveniently and accurately adjusted in combination with the scale inside the adjustment slot 1413. Subsequently, the staff can conveniently and accurately adjust the internal material storage space of the adjustment slots 1413 on the four turntables 1412 through the same operation, thereby accurately proportioning cement, aggregate, admixture and water respectively.

[0061] Then the staff can drive the second servo motor 1404 on the first processing box 1401. Under the driving action of the second servo motor 1404, the driving shaft 1405 can be driven to rotate counterclockwise. At this time, under the counterclockwise rotation of the driving shaft 1405, the limiting rod 1407 on the second spring 1406 can be engaged in the limiting groove 1409 inside the driven cylinder 1408, and the driven cylinder 1408 can be pushed to rotate synchronously. At this time, under the rotation of the driven cylinder 1408, the third gears 1411 can be driven to rotate stably through the second gear 1410, and then the corresponding turntable 1412 can be driven to rotate synchronously. At this time, under the continuous rotation of the turntable 1412, the adjusting groove 1413 on the turntable 1412 can be driven to align with the first The first material discharge trough 1421 on the material guide plate 1420 is aligned, and then aligned with the second material discharge trough 1423 on the second material guide plate 1422. When the adjustment trough 1413 is aligned with the first material discharge trough 1421 first, the raw materials in the storage trough 1402 can automatically fall into the adjustment trough 1413 with the internal space adjusted. Then, when the adjustment trough 1413 is aligned with the second material discharge trough 1423, a certain amount of raw materials can be automatically transported to the second processing box 1601 for subsequent mixing treatment. Similarly, under the synchronous rotation of the four turntables 1412, the proportioning and discharging of cement, aggregate, admixture and water can be completed conveniently, and intermittent discharging can be performed, avoiding the problem of agglomeration caused by the one-time addition of a large amount of raw materials, which affects the mixing rate and mixing effect.

[0062] And in the process of unloading, the second servo motor 1404 can drive the sliding rod 1603 to rotate synchronously through the driving shaft 1405. At this time, under the continuous rotation of the sliding rod 1603 and the limiting effect of the sliding groove 1606, the reinforcing rod 1607 and the fixed frame 1608 can be driven to rotate simultaneously through the sliding plate 1605. At the same time, during the rotation of the fixed frames 1608 on the upper and lower sides, the guide plate 1609 can be driven to intermittently contact the guide block 1602. At this time, under the guiding effect of the guide plate 1609 and the guide block 1602, the third spring 1604 can be used to push the reinforcing rod 1607 and the fixed frame 1608 in the rotation process to perform automatic and stable reciprocating motion up and down. Through the sliding groove 1606 on the sliding plate 1605, the sliding plate 1605 can be ensured to perform stable up and down reciprocating motion on the sliding rod 1603, thereby ensuring the stability of the up and down reciprocating motion of the reinforcing rod 1607 and the fixing frame 1608. By utilizing the rotation and up and down reciprocating motion of the fixing frame 1608 and each reinforcing rod 1607, in conjunction with each first cutting blade 1610, the second cutting blade 1611 and the mixing plate 1612, the cement raw material and the ingredients can be fully and efficiently mixed and stirred. Under the continuous motion of each first cutting blade 1610 and each second cutting blade 1611, the caking phenomenon can be effectively avoided, and the mixing rate and mixing effect can be further improved.

[0063] When the feeding work is finished but the mixing work is not finished, the driving shaft 1405 on the second servo motor 1404 can be driven to rotate clockwise. At this time, under the clockwise rotation of the driving shaft 1405, the limiting rods 1407 on each second spring 1406 can be driven to move along the inclined surface of the limiting groove 1409 in the driven cylinder 1408. At this time, the limiting rods 1407 cannot drive the driven cylinder 1408 to rotate synchronously, so the second gear 1410 cannot drive the turntable 1412 on each third gear 1411, and the feeding work can no longer continue. Although the driving shaft 1405 is turned around, The sliding rod 1603 rotates clockwise, but does not affect the working state of the sliding rod 1603. The clockwise and counterclockwise rotations of the sliding rod 1603 drive the high-efficiency stirring assembly 16 to produce the same overall mixing and mixing effect. Therefore, after the loading work is completed, the loading work can be completed and the mixing work can be continued. In addition, the first processing box 1401 and the second processing box 1601 on both sides of the trolley main frame 1 can be used to alternately prepare concrete. After the concrete on one side is prepared, the drive can be stopped to carry out the subsequent concrete transportation, while the concrete on the other side is being prepared. By alternating the work, the continuous transportation of concrete can be ensured.

[0064] When the grouting work begins, the mixed concrete inside the second processing box 1601 can be sucked and transported to the first connecting frame 705 through the first conveying pipe 713 on the first concrete conveying pump 712. At this time, under the continuous driving action of the first servo motor 709, the scraper rods 710 can be driven to rotate through the output shaft, and the concrete can be continuously stirred in conjunction with the stirring rods 711 to ensure the uniformity of the concrete and prevent the concrete from adhering to the inner wall of the first connecting frame 705, affecting the subsequent material storage and conveying work. Subsequently, under the driving action of the first hydraulic rod 701, the first connecting frame 705 can be pushed upward by the support plate 702 until the third connecting pipe 729 is aligned with the fifth connecting pipe 12 on the fourth connecting pipe 11 at the bottom, and then driven by the third hydraulic rod 739. Under the circumstance, the third connecting pipe 729 can be pushed by the connecting plate 731 to stably insert into the fifth connecting pipe 12 on the fourth connecting pipe 11 at the bottom, and the rubber ring 730 can be used to perform convenient and stable sealing docking work. Subsequently, under the driving action of the second concrete delivery pump 715, the concrete in the first connecting frame 705 can be sucked through the second delivery pipe 716 and delivered to the transfer frame 717, and then can be stably delivered to the first connecting pipes 718 on both sides. Subsequently, the concrete passes through the openings between the various blockers 723 through the first connecting pipe 718 and is stably delivered to the rubber hose 728 on the second connecting pipe 727, and then is automatically delivered to the first grouting pipes 8 on both sides through the third connecting pipe 729, the fifth connecting pipe 12 and the fourth connecting pipe 11, so as to perform grouting and pouring of the bottom concrete.

[0065] After the grouting of the bottom layer of concrete is completed, the third hydraulic rod 739 can be driven again to drive the third connecting pipe 729 to move away from the fifth connecting pipe 12 on the bottom fourth connecting pipe 11 through the connecting plate 731, and then the staff can disassemble the first grouting pipe 8 to make it separate from the grouting window 4, and then the staff can block the grouting window 4 of the bottom layer of the template 3. At this time, through repeated operations, the first hydraulic rod 701 can push the first connecting frame 705 to continue to move upward until the third connecting pipe 729 is aligned with the fifth connecting pipe 12 on the middle-layer fourth connecting pipe 11, and then under the driving action of the third hydraulic rod 739, the third connecting pipe 729 can be pushed through the connecting plate 731 to stably insert into the fifth connecting pipe 12 on the middle-layer fourth connecting pipe 11. Through the same operation, the second grouting pipe 9 can be used to conveniently complete the grouting of the middle layer of concrete. Similarly, through the above-mentioned same operation, the third grouting pipe 10 can be used to complete the grouting of the upper layer of concrete, so that the pouring of the top layer of concrete can be completed conveniently and stably.

[0066] Then the staff can drive the third hydraulic rod 739. Under the driving action of the third hydraulic rod 739, the racks 734 on both sides can be driven to move downward synchronously through the push plate 733. Under the downward movement of the racks 734, the first gear 735 connected by meshing can drive the rotating block 738 on the rotating shaft 736 to rotate upward at the same time, thereby driving the third hydraulic rods 739 on both sides to rotate upward at the same time. At this time, under the movement of the third hydraulic rod 739, the third connecting pipe 729 on the rubber hose 728 can be driven to move to a vertical state through the connecting plate 731. At this time, the third connecting pipe 729 switches from a horizontal state to a vertical state and is located directly below the embedded pipe 5. At this time, under the driving action of the third hydraulic rod 739, the third connecting pipe 729 can be driven to be conveniently connected with the embedded pipe 5, so that the pouring of the top concrete can be completed conveniently and stably.

[0067] During the concrete grouting process, the staff can rotate the worm 719 on the second connecting frame 714. Under the rotation of the worm 719, the worm wheels 720 meshing on both sides can be driven to rotate simultaneously. During the rotation of the worm wheels 720, the corresponding guide rods 722 can be moved through the first guide grooves 721 to slide within the second guide grooves 726 on the sealing plate 725. At this time, under the guiding action of the second guide grooves 726, each guide rod 722 can drive the corresponding block 723 to move conveniently and stably. By using the dislocation movement of each block 723, the size of the middle opening can be conveniently adjusted. At this time, the opening size of the concrete conveying channel between the first connecting pipe 718 and the second connecting pipe 727 can be conveniently and stably adjusted and controlled. By conveniently adjusting the size of the concrete conveying channel opening, the precise control of the concrete conveying flow rate is achieved. By regulating the concrete conveying flow rate, an appropriate flow rate can be adopted, which helps to fill the concrete into every corner, avoid bubbles and gaps, and improve the compactness of the concrete, thereby effectively improving the workability of the concrete and the final engineering quality.

[0068] After the work of the grouting trolley is completed, the first grouting pipe 8, the second grouting pipe 9 and the third grouting pipe 10 can be disassembled by removing the bolts, thereby ensuring the convenience of their subsequent transportation and reuse, and the staff can pull the clamping rod 708 on the positioning frame 706 outward until the clamping rod 708 moves out of the clamping groove 704 on the positioning rod 703, and the first connecting frame 705 can move out of the support plate 702, thereby conveniently completing the disassembly and separation between the main body of the multifunctional grouting assembly 7 and the trolley main frame 1, thereby ensuring the convenience of the subsequent overall disassembly and assembly of the grouting trolley, and at the same time ensuring the convenience of the subsequent transportation of the grouting trolley, and When the multifunctional grouting assembly 7 main body needs to be installed, it is only necessary to pull outward the latching rod 708 on the positioning frame 706 in advance, and then place the first connecting frame 705 on the support plate 702, and ensure that the positioning frame 706 is stably engaged with the positioning rod 703 on the top of the support plate 702 to complete the positioning. Then the staff can release the latching rod 708 on the positioning frame 706. At this time, under the elastic action of the first spring 707, the latching rod 708 can be driven to automatically engage with the latching groove 704 on the positioning rod 703, so as to conveniently complete the engagement and installation of the multifunctional grouting assembly 7 main body and ensure the stability and safety of the subsequent working state of the multifunctional grouting assembly 7 main body.
