As shown in fig. 5, the bottom surface of the baffle 11 is provided with a bar-shaped groove 30 at a position corresponding to the protrusion 25; the bottom of the strip-shaped groove 30 is fixedly connected with a plurality of elastic rods 31 which are uniformly arranged, and one end of each elastic rod 31, which is far away from the bottom of the strip-shaped groove 30, is spherically arranged; when the baffle 11 slides along the top surface of the lower die 3 with the sliding plate 27, the elastic rods 31 in the strip grooves 30 collide with the protrusions 25 on the top surface of the lower die 3, so that the elastic rods 31 vibrate, the vibration elastic rods 31 transmit the vibration to the baffle 11, and concrete between the baffles 11 is further promoted to fall into the lower die 3 through the holes on the surface of the reinforcement cage, and the probability of the concrete sliding from the surface of the reinforcement cage is reduced.
As shown in fig. 1 and 7, the carrier assembly includes a base 32; the base 32 is fixedly connected with the top surface of the object stage 1, and the top surface of the base 32 is arranged in an arc shape; the outer side surfaces of the upper die 4 and the lower die 3 are fixedly connected with a plurality of arc plates 33 which are uniformly arranged, and the surface arc plates 33 of the upper die 4 and the lower die 3 correspond to each other; an arc-shaped groove 34 is formed in the top surface of the base 32 at a position corresponding to the arc-shaped plate 33, and the arc-shaped groove 34 is matched with the arc-shaped plate 33; the arc-shaped groove 34 is rotationally connected with a driving wheel 35, and the driving wheel 35 is driven by a motor; when the working process is finished, after the upper die 4 and the lower die 3 are fixed, the upper die 4 and the lower die 3 can be put on the top surface of the base 32, the arc plate 33 can extend into the arc groove 34, at the moment, a user starts the driving wheel 35 in the arc groove 34 to rotate, and the driving wheel 35 is in contact with the arc plate 33, so that the arc plate 33 can be driven to rotate, and further the upper die 4 and the lower die 3 fixedly connected with the arc plate 33 are driven to rotate together, thereby completing the centrifugal forming operation of concrete, omitting the operation of hanging the upper die 4 and the lower die 3 to other places by the user for centrifugal forming, further simplifying the processing flow and improving the production efficiency.
In operation, when a user needs to produce a concrete pipe, the embodiment of the invention can be used, firstly, the user needs to put a reinforcement cage into the lower die 3 on the bearing component through a hoisting device, then control the two portal frames 5 to move to the top of the lower die 3 along the sliding rail 6, then the hoisting device 7 on the surface of the sliding rail 6 can move to the top of the lower die 3 along the sliding rail 6, the injection box 8, the guide pipe 10 and the baffle 11 are lowered to the top surface of the upper die 4, then the screw rod 2 at the bottom of the injection box 8 is rotated, the concrete in the injection box 8 is pushed to the guide pipe 10, the guide pipe 10 guides the concrete between the two baffle 11, and when the concrete is injected into the lower die 3, the hoisting component also drives the injection box 8, the guide pipe 10 and the baffle 11 to move along the upper die 4, and then the whole lower die 3 is filled with a proper amount of concrete, after the concrete is injected into the lower mold 3, the portal frame 5 moves to the top of the other lower mold 3 requiring injection with the lifting assembly, the injection box 8, the guide pipe 10 and the baffle 11, and the next round of injection is performed, so that the lower mold 3 completing the injection requires a user to lift the upper mold 4 to the top surface of the lower mold 3, then the upper mold 4 and the lower mold 3 are fixedly connected together through bolts, the subsequent centrifugal molding operation of the concrete is performed, the concrete is poured into the guide pipe 10 through the screw rod 2 at the bottom of the injection box 8, the concrete is guided between the two baffles 11 by the guide pipe 10 and finally guided into the lower mold 3, the two baffles 11 block during the process, the concrete accumulated on the steel reinforcement cage can be prevented from directly sliding off the surface of the steel reinforcement, the concrete injection is uneven, and the quality of the final product is poor, or the concrete falls to the side of the lower mold 3, which affects the closing operation of the upper mold 4.
When the pouring box 8 is used for pouring concrete into the guide pipe 10, the driving component in the connecting box 12 can drive the guide rod 13 to move up and down, and the guide rod 13 moving up and down can continuously stir the concrete in the guide pipe 10, so that the concrete can enter between the two baffles 11 more easily through the guide pipe 10, and the guide rod 13 can stir the concrete at the baffles 11 because the guide rod 13 extends between the baffles 11, so that the concrete can pass through gaps on the surface of the reinforcement cage more easily and enter the interior of the reinforcement cage, the accumulation of the concrete on the surface of the reinforcement cage is avoided, and part of the concrete is caused to slide down from the surface of the reinforcement cage, and the waste of the concrete and the uneven concrete in the lower die 3 are caused.
When the user needs the guide rod 13 to move up and down, the user needs to drive the rotating rod 14 to rotate through an external motor, the rotating rod 14 drives the straight plates 15 to rotate, the paired straight plates 15 drive the connecting rods 16 between the straight plates to rotate, and the rotating connecting rods 16 drive the tops of the guide rods 13 to do circular motion, so that the bottoms of the guide rods 13 move up and down, and the starting positions of the guide rods 13 are inconsistent, so that the guide rods 13 do staggered motion, and the stirring effect on concrete is improved.
When the straight plate 15 and the connecting rod 16 drive the guide rod 13 to move up and down, the limiting block 17 on the side wall of the guide rod 10 can play a limiting role on the guide rod 13, so that the bottom of the guide rod 13 is prevented from shaking randomly when the end part of the guide rod 13 moves circularly, and the guide rod 13 is further caused to continuously strike the guide rod 10, and abrasion of the guide rod and the guide rod is further increased.
When the guide rod 13 moves up and down, the guide rod 13 also drives the pressing rod 18 to move up and down, if the pressing rod 18 directly presses the steel reinforcement cage in the lower die 3, the pressing rod 18 cannot continuously descend due to the obstruction of the steel reinforcement cage, the guide rod 13 continuously moves towards the lower die 3, the bottom of the guide rod 13 is pressed into the sliding groove 19 at the end part of the pressing rod 18, the spring 20 is compressed, the guide rod 13 is prevented from being propped against by the steel reinforcement cage, the up and down vibrating operation cannot be completed, and the guide rod 13 is damaged.
When the external motor drives the rotating rod 14 to rotate, the rotating rod 14 also drives the driving disc 21 to rotate, then the driving disc 21 drives the driven disc 22 to rotate through the belt 23, and finally the rotating driven disc 22 drives the stirring rod 24 to rotate, so that stirring of the concrete in the injection box 8 is realized, and uniformity of the concrete is further ensured.
After the user finishes pouring the concrete, the user needs to hang the upper die 4 to the top of the lower die 3, then the user needs to align the groove 26 on the side edge of the upper die with the protrusion 25 on the side edge of the lower die 3, then buckle the upper die 4 on the top surface of the lower die 3, and insert the protrusion 25 on the lower die 3 into the groove 26 on the surface of the upper die 4, so as to preliminarily fix the upper die 4 and the lower die 3, avoid the dislocation of the upper die 4 and the lower die 3, and further facilitate the user to fix the upper die 4 and the lower die 3 together through bolts.
When two baffle plates 11 are buckled on the top surface of the lower die 3, the sliding plate 27 at the bottom of the baffle plates 11 can be pressed on the side edge of the lower die 3, and when the baffle plates 11 move with the sliding plate 27, the pulley 29 in the limiting groove 28 at the bottom surface of the sliding plate 27 can be contacted with the surface of the lower die 3, and the friction force generated when the sliding plate 27 moves is reduced through the rotation of the pulley 29, so that the abrasion caused by the direct contact between the bottom of the baffle plates 11 and the lower die 3 is avoided.
When the baffle plates 11 slide along the top surface of the lower die 3 with the sliding plate 27, the elastic rods 31 in the strip-shaped grooves 30 collide with the protrusions 25 on the top surface of the lower die 3, so that the elastic rods 31 vibrate, and the vibration elastic rods 31 transmit the vibration to the baffle plates 11, so that concrete between the baffle plates 11 is promoted to fall into the lower die 3 through the holes on the surface of the reinforcement cage, and the probability of the concrete sliding from the surface of the reinforcement cage is reduced.
After the upper die 4 and the lower die 3 are fixed, the upper die 4 and the lower die 3 can be put on the top surface of the base 32, the arc plate 33 can extend into the arc groove 34, at the moment, a user stops starting the driving wheel 35 in the arc groove 34 to rotate, and the driving wheel 35 is in contact with the arc plate 33, so that the arc plate 33 can be driven to rotate, and then the upper die 4 and the lower die 3 fixedly connected with the arc plate 33 are driven to rotate together, thereby completing the centrifugal forming operation of concrete, omitting the operation of hanging the upper die 4 and the lower die 3 to other places by the user for centrifugal forming, further simplifying the processing flow and improving the production efficiency.
