[0026] In order to better understand the purpose, structure and function of the present invention, the intelligent trolley casting system of the present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 6As shown, an intelligent trolley casting system of the present invention comprises a steel frame 31, a formwork 30 mounted on the steel frame 31, and a casting opening 32 formed in the formwork 30. A support base 33 slidably connected to a track 37 is provided at the bottom end of the steel frame 31, and a pusher is provided on the support base 33 to drive the movement of the steel frame 31. A mounting frame 1 is located on the top surface of the steel frame 31, and multiple grouting pipes 2 are distributed on the side walls of the mounting frame 1. A feeding device is provided on the mounting frame 1 that is connected to the grouting pipes 2, and the grouting pipes 2 can extend from their corresponding casting openings 32. The support base 33 and the steel frame 31 are moved by a driver, and the various components mounted on the steel frame 31 are moved to appropriate positions in the tunnel, forming a grouting gap between the formwork 30 and the inner wall of the tunnel. The feeding device is then connected to the grouting pipes 2, and the feeding device directly delivers the material into the grouting pipes 2, which then transports the material through the grouting pipes 2 into the gap between the tunnel and the formwork 30. The mounting frame 1 is U-shaped, and grouting pipes 2 are distributed on both vertical plates of the mounting frame 1 .

[0028] The support base 33 is defined by a guide slot 34 running along its length. The pusher comprises a roller 35 that rotates within the guide slot 34. A track 37 is positioned within the guide slot 34 and abuts against the roller 35. Furthermore, a drive motor 36 connected to an external power source is mounted on the sidewall of the support base 33. A drive shaft connects the drive motor 36 to the roller 35. To move the trolley, the drive motor 36 is activated, which rotates the roller 35 via the shaft. This rotation, in turn, moves the trolley along the track 37. Once the trolley reaches the desired position, the drive motor 36 is stopped.

[0029] Specifically, the feeding device includes a movable platform 3 that slides onto a mounting frame 1 and is connected to the mounting frame 1 via a drive mechanism. A boss is provided on the movable platform 3, on which a delivery pipe 11 and a power unit are mounted. The delivery pipe 11 is rotatably mounted on the boss. One end of the delivery pipe 11 is connected to an external feed pump, and the other end can be connected to any grouting pipe 2. The power unit facilitates the delivery pipe 11's outlet end to change direction on the boss, facilitating communication between the delivery pipe 11 and the grouting pipe 2 mounted on the two vertical plates of the mounting frame 1. A telescopic tube 17 is provided at the outlet end of the grouting pipe 2, with a first extension pipe 19 mounted on the telescopic end. A first retaining ring 18 is also mounted on the first extension pipe 19. The grouting pipe 2 is connected to the first retaining ring 18 via a telescopic cylinder 16. A fixed block 15 is provided on the grouting pipe 2, and the telescopic cylinder 16 is mounted on the grouting pipe 2 via the fixed block 15. The drive mechanism drives the movable platform 3 to slide along the mounting frame 1, aligning the first extension pipe 19 on the delivery pipe 11 with the target grouting pipe 2. Afterwards, the power device drives the conveying pipe 11 to rotate, so that the feeding end of the first extension pipe 19 is aligned with the feeding end of the grouting pipe 2, and the telescopic cylinder 16 is started. The telescopic cylinder 16 drives the first extension pipe 19 to move toward the corresponding grouting pipe 2 through the first retaining ring 18, and completes the docking of the first extension pipe 19 and the grouting pipe 2. The external feeding pump pumps concrete into the conveying pipe 11 and injects it into the gap between the tunnel and the trolley through the grouting pipe 2.

[0030] The telescopic cylinder 16 mentioned above is preferably an electric push rod, but can also be a hydraulic cylinder, without making too many restrictions here.

[0031] Among them, the driving device for driving the mobile platform 3 to move on the mounting frame 1 includes a first motor 6 provided on the side wall of the mobile platform 3, and the first motor 6 is connected to and powered by an external power supply. Two fixed plates 4 are provided on the side wall of the mobile platform 3 below the first motor 6, and support shafts 5 are rotatably provided on the two fixed plates 4, and driving gears 9 are provided at both ends of the support shafts 5. The first motor 6 is connected to the support shafts 5 through a transmission part. In addition, racks 10 are provided at positions corresponding to each driving gear 9 on the mounting frame 1, and the driving gears 9 are engaged with the racks 10. After the first motor 6 is started, the support shaft 5 is driven to rotate through the transmission part. The driving gears 9 at both ends of the support shaft 5 rotate accordingly. Since the driving gears 9 are engaged with the racks 10 fixed on the mounting frame 1, the rotation of the driving gears 9 is converted into linear motion of the mobile platform 3. Among them, the driving gears 9 are symmetrically arranged on both sides of the mobile platform 3 and are linked through the same support shaft 5, so that the mobile platform 3 can run smoothly and prevent it from deflecting or getting stuck, so as to improve the movement stability of the mobile platform 3. As Figure 1 As shown, the rack 10 is laid along the entire length of the mounting frame 1, so that the movable platform 3 can move freely in the mounting frame 1, flexibly switching the position of the delivery pipe 11, and facilitating the connection between the first extension pipe 19 and the grouting pipe 2.

[0032] The transmission mechanism described above includes a worm 7 at the output end of a first motor 6 and a worm wheel 8 mounted on a support shaft 5, with the worm 7 meshing with the worm wheel 8. When the first motor 6 is started, the worm 7 at its output begins to rotate, and the worm wheel 8 meshing with the worm also rotates, thereby enabling the worm wheel 8 to drive the support shaft 5. The transmission mechanism of the worm wheel 8 and the worm 7 is self-locking, preventing the movable platform 3 from shifting due to load or vibration when power is turned off, thereby improving the positioning stability of the movable platform 3 relative to the mounting frame 1.

[0033] like Figure 3 As shown, the power device for driving the conveying pipe 11 to rotate on the boss includes a reduction motor 12 provided on the boss, a first gear 13 provided on the output end of the reduction motor 12, and a first ring gear 14 provided on the conveying pipe 11, and the first gear 13 and the first ring gear 14 are engaged. When the moving platform 3 drives the conveying pipe 11 to move to the appropriate position, the reduction motor 12 can be started, and the reduction motor 12 will drive the first gear 13 at its output end to rotate, and the first gear 13 will engage with the first ring gear 14 fixed on the conveying pipe 11 for transmission, and the ring gear will also rotate, and will drive the conveying pipe 11 to rotate on the boss, thereby changing the position of the discharge port of the conveying pipe 11, and facilitating the communication between the conveying pipe 11 and the grouting pipes 2 on the two vertical plates of the mounting frame 1.

[0034] Preferably, a pushing assembly for assisting the movement of materials is provided on each grouting pipe 2. The pushing assembly can be arranged so that the delivery pipe 11 is connected to the grouting pipe 2, and the pushing assembly is activated while the delivery pipe 11 is delivering materials into the grouting pipe 2. During the operation of the pushing assembly, the materials will be assisted to move toward the discharge port of the grouting pipe 2, and when the delivery pipe 11 is separated from the grouting pipe 2, the pushing assembly can also clean the materials at the feed port of the grouting pipe 2 to prevent the materials from falling and causing waste.

[0035] The pushing assembly includes a pushing portion provided on the grouting pipe 2 and a driving portion provided on the mounting frame 1 for driving the pushing portion to rotate. The pushing portion specifically includes a bracket 25 provided on the mounting frame 1, and the bracket 25 is located below the corresponding grouting pipe 2. Among them, the bracket 25 is composed of a horizontal plate and a vertical plate. A second extension pipe 24 is provided on the bracket 25, that is, the second extension pipe 24 is provided on the vertical plate of the bracket 25, and a sealing ring 23 is rotatably provided between the second extension pipe 24 and the grouting pipe 2, and a connecting ring 27 is also provided in the sealing ring 23 between the second extension pipe 24 and the grouting pipe 2.

[0036] like Figure 4 and Figure 5As shown, an auger 26 is placed in the gap within each grouting pipe 2, and one side of the auger 26 is connected to the connecting ring 27. The telescopic cylinder 16 drives the first extension pipe 19 to move through the retaining ring 18, and directly inserts the second extension pipe 24 into the first extension pipe 19 to achieve the connection between the two. When the first extension pipe 19 and the second extension pipe 24 are connected and begin to convey materials, the drive unit starts the drive unit to drive the sealing ring 23 to rotate, and the sealing ring 23 transmits power to the auger 26 through the connecting ring 27. The rotating auger 26 generates a propulsion force in the grouting pipe 2, assisting the material to move toward the discharge port. And when the first extension pipe 19 and the second extension pipe 24 are separated, the pushing assembly continues to work for a period of time. The rotation of the auger 26 pushes the material remaining at the feed port of the grouting pipe 2 toward the discharge port, thereby reducing the residual material in the pipeline and preventing the material in the second extension pipe 24 from falling and causing waste.

[0037] The inner diameter of the connecting ring 27 is the same as the inner diameter of the second extension tube 24 and the inner diameter of the grouting pipe 2. This facilitates the connection of the auger 26 to the connecting pipe, and the auger 26 is flush with the feed port of the first extension tube 19 near the feed end of the grouting pipe 2, so that the auger 26 can clean the material inside the second extension tube 24 and prevent the material inside the second extension tube 24 from falling.

[0038] Specifically, the drive unit includes a second motor 21 mounted on the mounting frame 1, a second gear 22 mounted on the second motor 21, and a second ring gear 20 disposed on the outer surface of the sealing ring 23. The second gear 22 meshes with the second ring gear 20. When the second motor 21 is started, it drives the second gear 22 at its output end to rotate. The second gear 22 drives the sealing ring 23 to rotate via the second ring gear 20. Ultimately, the sealing ring 23 drives the auger 26 inside the grouting pipe 2 and the second extension pipe 24 to rotate via the connecting ring 27.

[0039] As another preferred embodiment, a sealing assembly is provided at the feed end of the second extension tube 24, and the sealing assembly includes an airbag 28 disposed outside the second extension tube 24, and an air pump and an air extraction pump 291 disposed on the bottom surface of the bracket 25. The air pump and the air extraction pump 291 are respectively connected to the airbag 28 via connecting tubes. When the first extension tube 19 is connected to the second extension tube 24, the air pump inflates the airbag 28 through the connecting tube. The outer layer of the inflated airbag 28 will closely adhere to the outer wall of the first extension tube 19, while the inner layer of the airbag 28 will be connected to the outer wall of the second extension tube 24, so that the airbag 28 forms an annular sealing band between the inner wall of the first extension tube 19 and the outer wall of the second extension tube 24, establishing a reliable sealing interface to prevent material leakage from between the first extension tube 19 and the second extension tube 24. After pouring is completed, the air pump 291 withdraws the gas to shrink the airbag 28, separating the airbag 28 from the inner wall of the first extension tube 19 and releasing the seal with the first extension tube 19. The first extension tube 19 can then be removed from the second extension tube 24. The air pump 291 and the air pump are both connected to an external power source.

[0040] Instructions for use: Start the driving machine 36, which drives the roller 35 to rotate through the transmission shaft. The rotation of the roller 35 drives the trolley to move along the track 37. When the trolley moves to the appropriate position, the driving machine 36 can be stopped. Then, the mobile platform 3 is moved to the appropriate position according to the needs, and then the power device is used to drive the conveying pipe 11 to rotate on the boss to change the angle so that the first extension tube 19 on the conveying pipe 11 is aligned with the required grouting tube 2. Then, the telescopic cylinder 16 is started. The telescopic cylinder 16 drives the first extension tube 19 to be inserted into the second telescopic tube 17 through the first retaining ring 18. Then, the air pump is started. The air pump 29 inflates the air bag 28 through the connecting pipe, and the air bag 28 forms a seal between the first extension tube 19 and the second extension tube 24. Then, the material is conveyed into the second extension tube 24 through the first extension tube 19. When the first extension tube 19 needs to be separated from the second extension tube 24 , the air pump 291 withdraws the gas in the airbag 28 to separate the airbag 28 from the inner wall of the delivery tube 11 , and then the first extension tube 19 is pulled away from the second extension tube 24 .
