[0015]Example 1

[0016]A sprinkler curing equipment for lining concrete used in tunnel construction, such asFigure 1-2As shown, it includes a bottom plate 1, a roller 2, a universal wheel 3, a water storage tank 4, a servo motor 5, a sprinkler assembly 6 and a swing assembly 7. The bottom right side of the bottom plate 1 is provided with a roller 2 that rotates symmetrically forward and backward, and the bottom left of the bottom plate 1 There is a universal wheel 3 on the front and back symmetrically rotating side. The top right rear side of the bottom plate 1 is connected with a water storage tank 4 by bolts. A swing assembly 7 is provided between 1 and the output shaft of the servo motor 5.

[0017]The sprinkler assembly 6 includes a support frame 601, a guide sleeve 602, a first shunt pipe 603, a first spring 604, a first spray head 605, a water pump 606, a water inlet pipe 607, and a water outlet pipe 608. The top left side of the bottom plate 1 is fixedly connected with a support frame 601, the front and rear sides of the support frame 601 are equipped with guide sleeves 602, a first shunt pipe 603 is slidably arranged between the guide sleeves 602, and a first spring 604 is connected between the first shunt pipe 603 and the guide sleeve 602. A branch pipe 603 is equipped with first spray heads 605 evenly spaced on the outside, a water pump 606 is installed in the middle of the top of the bottom plate 1, and a water inlet pipe 607 is connected to the right of the water pump 606. The outlet pipe 608 is connected with the first branch pipe 603.

[0018]The swing assembly 7 includes a first rotation shaft 701, a first transmission wheel 702, a first belt 703, a second transmission wheel 704, a second rotation shaft 705, a third transmission wheel 706, a bevel gear 707, a third rotation shaft 708, and a toothless gear 709, curved rack 710, second belt 711 and rack frame 712, the top right front side of the bottom plate 1 is rotatably provided with a first rotating shaft 701 through a bearing seat, and the output shaft of the servo motor 5 is connected to the first rotating shaft 701 There is a first transmission wheel 702, a first belt 703 is wound between the first transmission wheels 702, a second transmission wheel 704 is connected to the rear of the first rotation shaft 701, and a second rotation shaft 705 is rotatably arranged at the front of the support frame 601. A third transmission wheel 706 is connected to the second rotation shaft 705, a second belt 711 is wound between the third transmission wheel 706 and the second transmission wheel 704, and the front part of the support frame 601 is rotatably provided with a third rotation shaft 708 and a second rotation shaft 705 The back end and the right end of the third rotating shaft 708 are welded with bevel gears 707, and the bevel gears 707 mesh with each other. The left end of the third rotating shaft 708 is welded with a toothless gear 709. The inner top of the first shunt 603 is connected with a curved rack 710 and The rack frame 712 and the toothless gear 709 mesh with the arc-shaped rack 710 and the rack frame 712 respectively.

[0019]This equipment can be used when people need to sprinkle the concrete inside the tunnel for curing. First, put a sufficient amount of water in the water storage tank 4, and then use a truck to pull the equipment forward. Under the action, the equipment can move smoothly with the truck. During this process, the servo motor 5 and sprinkler assembly 6 are activated to sprinkle water on the inner wall of the tunnel, and the sprinkler assembly 6 is continuously rotated through the swing assembly 7 to increase sprinkling. When people do not need to sprinkle water on the tunnel, just turn off the servo motor 5 and sprinkler assembly 6.

[0020]When people need to sprinkle water on the inner wall of the tunnel through the sprinkler assembly 6, start the water pump 606. The water pump 606 transports the water in the water storage tank 4 to the first branch pipe 603 through the water inlet pipe 607 and the water outlet pipe 608, and then passes through the first sprinkler 605 Sprinkle water out. Due to the large volume of the equipment, the distance between the first nozzle 605 and the inner wall of the tunnel is relatively short, so the first nozzle 605 can spray water on the inner wall of the tunnel, when people do not need to spray water on the inner wall of the tunnel Just turn off the water pump 606.

[0021]When people need to drive the first shunt pipe 603 to continuously reciprocate through the swing assembly 7, the output shaft of the servo motor 5 will drive the first rotating shaft 701 to continuously rotate through the first transmission wheel 702 and the first belt 703, thereby driving the second transmission wheel 704 rotates continuously, and drives the second shaft 705 to continuously rotate through the third transmission wheel 706 and the second belt 711, thereby driving the third shaft 708 and the toothless gear 709 to continuously rotate through the engagement between the bevel gears 707. When the toothless gear When 709 meshes with the arc-shaped rack 710, it will drive the first shunt 603 to rotate forward, the first spring 604 on one side is compressed, and the first spring 604 on the other side is stretched. When the rack 710 is no longer meshed, under the action of the first spring 604, the first shunt tube 603 will reset. When the toothless gear 709 meshes with the rack frame 712, it will drive the first guide tube to rotate in the reverse direction. The spring 604 will also deform. When the toothless gear 709 is no longer meshed with the rack frame 712, under the action of the first spring 604, the first guide tube will automatically reset. Such reciprocation can make the first guide tube continuously The alternating forward and reverse rotations greatly increase the spray area.

[0022]Example 2

[0023]On the basis of Example 1, such asFigure 1-2As shown, it also includes a guide rod 8, a second shunt tube 9, a second nozzle 10, a second spring 11, and a contact block 12. The top left side of the bottom plate 1 is fixedly connected with a guide rod 8 symmetrically forward and backward, and the guide rods 8 slide The second branch pipe 9 is provided with a second branch pipe 9, a plurality of second nozzles 10 are installed evenly spaced on the second branch pipe 9, the second branch pipe 9 is connected with the outlet pipe 608, and the second branch pipe 9 is connected with the bottom plate 1. There is a second spring 11, the second spring 11 is sleeved on the guide rod 8, the bottoms of the front and rear sides of the first shunt pipe 603 are fixedly connected with contact blocks 12, and the contact blocks 12 are matched with the corresponding second shunt pipe 9.

[0024]It also includes a stirring rod 13. The rear end of the first rotating shaft 701 passes through the water storage tank 4 and is connected to the stirring rod 13, and the stirring rod 13 is located in the water storage tank 4.

[0025]When the first guide tube rotates, it will come into contact with the contact block 12 on one side, and push the contact block 12 and the second shunt tube 9 downwards. The second spring 11 is compressed, and the water can flow from the second nozzle 10 When the first guide tube is reset, the first guide tube is separated from the contact block 12. Under the action of the second spring 11, the contact block 12 and the second shunt tube 9 are both reset upwards, which can further increase the spray The area of ​​water.

[0026]People can put a curing agent in the water to maintain the concrete on the tunnel. The continuous rotation of the first rotating shaft 701 will drive the mixing plate to continuously rotate, thereby stirring the water in the water storage tank 4, so that the water and the curing agent are fully mixed .
