[0028] The present invention will be further described in detail below with reference to specific embodiments.
[0029] Please see Figure 1-8 The tunnel floor concrete pouring device provided in this embodiment includes a floor 1, two support columns 2 are fixedly installed on the top of the floor 1, a drive mechanism 3 is fixedly installed on the top of the two support columns 2, the drive mechanism 3 drives the mixing and stirring mechanism 4 to move horizontally on the floor 1, a pouring mechanism 5 is installed on the support columns 2, and a cleaning mechanism 6 is installed on the floor 1.
[0030] The cleaning mechanism 6 includes a cleaning tank 601, cleaning water spray pipes 602, nozzles 603, a guide plate 604, a filter steel mesh 605, a sponge filter plate 606, an equipment box 607, a water storage tank 608, and a delivery pump 609. The cleaning tank 601 and the equipment box 607 are fixed on the base plate 1. Two cleaning water spray pipes 602 are fixedly installed on the inner wall of the cleaning tank 601, and the two cleaning water spray pipes 602 are interconnected. Several nozzles 603 are fixedly installed on opposite sides of the two cleaning water spray pipes 602. The guide plate 604 is fixedly installed inside the cleaning tank 601. The filter steel mesh 605 and the sponge filter plate 606 are inserted into the inside of the cleaning tank 601. The water storage tank 608 and the delivery pump 609 are fixedly installed inside the equipment box 607. The equipment box 607 is fixed on the base plate.
[0031] The mixing mechanism 4 includes a fixed screw 403, a plug-in fixing ring 404, a plug-in connecting ring 405, a servo motor 406, a mixing shaft 407, and a mixing rod 408. The drive box has a limit groove, and the plug-in plate 401 extends out of the drive box from the limit groove. A threaded seat 402 is fixed on the plug-in plate 401. The plug-in connecting ring 405 is detachably connected to the threaded seat 402 through the fixed screw 403. The plug-in fixing ring 404 is fixed inside the plug-in connecting ring 405. The fixed end of the servo motor 406 is fixedly connected to the plug-in fixing ring 404. The output shaft of the servo motor 406 passes through the plug-in fixing ring 404 and is fixedly connected to the mixing shaft 407. The output shaft of the servo motor 406 is rotatably connected to the plug-in fixing ring 404. The mixing rod 408 and the mixing shaft 407 are fixedly connected. Both the mixing rod 408 and the mixing shaft 407 are movably connected to the pouring mechanism 5.
[0032] The casting mechanism 5 includes a casting mold 501, connecting pieces 502, snap-fit plates 503, connecting plates 506, and threaded connecting rods 507. There are two connecting pieces 502, which are fixedly connected to both ends of the casting mold 501. There are two snap-fit plates 503, which are slidably connected to two support columns. Each snap-fit plate 503 has a snap-fit column 504 fixed to its top, and the two connecting pieces 502 snap-fit into the two snap-fit columns 504 respectively. Each support column has a threaded block 505 fixed to it. There are two connecting plates 506, which are fixed to the two snap-fit plates 503 respectively. There are two threaded connecting rods 507, which are rotatably connected to the two connecting plates 506 respectively. The two threaded connecting rods 507 pass through the two connecting plates 506 and are threadedly connected to the threaded blocks 505. The stirring rod 408 and the stirring shaft 407 are both movably connected to the casting mold 501. The casting mechanism 5 designed in this way can adjust the relative height of the casting mold 501. Specifically, when adjustment is needed, the connection between the threaded connecting rod 507 and the threaded block 505 is loosened, and the snap-fit plate 503 is driven to slide on the support column, thereby causing the connecting piece 502 to slide relative to the support column. The connecting piece 502 causes the casting mold 501 to slide relative to the support column, thereby adjusting the relative height of the casting mold 501.
[0033] Specifically, when deep cleaning of the stirring shaft 407 and stirring rod 408 is required, firstly, the fixing screw 403 connecting the insert connecting ring 405 and the threaded seat 402 should be removed; then, gently lift the insert connecting ring 405 upwards to allow it to detach smoothly from the insert plate 401. Since the insert plate has internal space for the stirring rod and stirring shaft to pass through, there will be no interference during removal; at this point, the entire structure including the servo motor 406, stirring shaft 407, and stirring rod 408 can be safely removed from the front of the drive box 301; subsequently, carefully remove these components from the insertion of the cleaning tank. The nozzle is inserted into the cleaning tank 601; finally, the delivery pump 609 is started, which draws cleaning fluid from the water storage tank 608 and forms a high-pressure water flow through the cleaning water spray pipe 602 and multiple precision-arranged nozzles 603 to thoroughly rinse the mixing shaft 407 and the mixing rod 408; this process not only efficiently removes residual concrete, but also recovers and purifies wastewater through the guide plate 604, the filter steel mesh 605 and the sponge filter plate 606. The purified wastewater is discharged from the drain outlet and transported to the water storage tank, realizing the effective recycling of resources, ensuring the long-term stable operation of the equipment while reducing maintenance costs.
[0034] Specifically, the drive motor 302 is installed on the left side of the drive box 301. It generates mechanical energy through power supply and transmits this energy to the threaded drive shaft 303. When the drive motor 302 starts, its output end drives the threaded drive shaft 303 to rotate. When the threaded drive shaft 303 is driven by the drive motor 302, it will make a spiral motion along its own axis. This motion mode can effectively convert the rotational force into linear thrust, thereby driving the mixing mechanism 4 to move left and right on the base plate. That is, the mixing mechanism can move inside the casting mold to achieve full mixing of the concrete in the casting mold 501.
[0035] Specifically, the mixing shaft 407 and the mixing rod 408 are the core working components of the mixing mechanism 4, which directly participate in the concrete mixing process. One end of the mixing shaft 407 is connected to the output end of the servo motor 406, and the other end extends into the inside of the casting mold 501, forming an integrated structure with the multi-layered mixing rod 408. The mixing rod 408 can continuously mix the concrete in the casting mold 501, reduce air bubbles in the concrete, and ensure the quality of the tunnel floor slab after subsequent processing.
[0036] In summary, this tunnel floor concrete pouring device solves the cleaning problem of the mixing components through the cleaning mechanism 6. During use, the delivery pump 609 draws water from the water storage tank 608 and uses the cleaning water spray pipe 602 and nozzle 603 to perform high-pressure rinsing on the core components of the mixing mechanism 4—the mixing shaft 407 and the mixing rod 408. The wastewater is recycled and reused through the guide plate 604 and a two-stage filtration system. This design not only prevents concrete from hardening and adhering to the surface of the mixing shaft 407 and the mixing rod 408, reducing maintenance costs, but also improves work efficiency, achieves environmental protection and energy saving, and significantly extends the service life of the equipment. It solves the problem that existing technologies do not have a cleaning structure designed for the mixing components, and if the concrete residue on the surface of the mixing components is not cleaned in time, it is easy to harden and adhere to the equipment surface, affecting the long-term performance of the equipment and increasing the difficulty and cost of maintenance.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
