[0032] According to the above technical solution, a steel slag permeable concrete road panel is a concrete road panel prepared according to a steel slag permeable concrete road panel preparation method.

[0033] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0034] 1. A flip unloading mechanism is provided, which uses a rotating motor to drive the rotating rod to rotate continuously, so that the incomplete gear and the rotating gear are intermittently meshed, and the rotating mold is driven to flip on the support frame, so that the concrete slab formed inside the rotating mold can be unloaded conveniently. The unloading method is simple, which provides great convenience for the staff to take out the formed concrete slab. The positioning block at one end of the rotating gear is limited by the embedded block. When pressurizing and shaping, the rotating gear and the rotating mold are kept stable and will not shake, so as to prevent the shaking and deflection of the rotating mold from causing the concrete to be unable to be pressurized and formed normally. The eccentric wheel rotates with the rotating rod, and its position away from the center of the circle will contact the lifting rod and squeeze it downward, so as to adjust the position of the embedded block, and release the limit on the rotating gear and the rotating mold when they rotate, so that the operation is more convenient.

[0035] The limiting round block and the limiting frame are used to limit and stabilize the top material cylinder. When the concrete is pressurized and formed, it is sealed flush with the bottom end of the rotating mold. After the forming is completed, when the top material cylinder rotates, the hydraulic telescopic rod and the shaping pressure plate can be used to press it down. The top material cylinder will push the concrete slab condensed inside the rotating mold to fall, so that it can fall automatically and cannot be unloaded manually, which is more convenient and safer.

[0036] 2. The hydraulic adjustment rod is used to drive the connection long plate and the buffer receiving plate to rise and fall, and the position height of the buffer receiving plate is adjusted. The buffer receiving plate buffers the concrete slab that falls from the rotating mold. The buffer spring absorbs the impact force when it falls, preventing the concrete slab from causing severe impact when it falls, resulting in damage to its own parts and making it unable to be used normally. The buffer receiving plate is in a lower position when the rotating mold is turned over, and will not collide with the rotating mold. After the rotating mold is turned over, the buffer receiving plate can rise to a certain height, so that the falling height of the concrete slab is reduced, reducing its falling impact force, and thus the unloading is more stable;

[0037] The pressure sensor is used to monitor the height of the buffer connecting plate, and then the volume weight of the concrete slab dropped on the buffer connecting plate is detected. The buffer connecting plate will change its position at different heights when the weight of the concrete slab is pressed down. The height of the buffer connecting plate is judged according to the different pressures felt by the pressure sensor. The weight of each batch of concrete slabs is tested to determine whether the concrete slabs are qualified. The monitoring method is simple, and the elastic airbag at the bottom of the pressure sensor has a certain buffering protection effect, so that the pressure sensor will not be damaged by impact.

[0038] 3. A cleaning and anti-sticking mechanism is provided, which utilizes a driving motor to drive the two-way screw rod to rotate, so that the two moving blocks move along the mounting frame, and the two ends of the driving rod are rotatably connected with the positioning vertical rod and the connecting vertical rod respectively. The driving rod will push the moving cross bar forward and slide along the guide plate. The cleaning scraper will cling to the bottom end of the shaping platen to scrape off the concrete residue adhered to the bottom thereof, and the scraped residue will directly fall into the dust collecting box, so that the bottom end of the shaping platen remains clean and flat, and the residue is uniformly collected without falling and scattering everywhere, and the bottom end of the shaping platen is cleaned after each pressing and shaping is completed, to prevent residue from adhering to its bottom and causing quality problems of the concrete slab prepared by subsequent pressing.

[0039] 4. The driving rack is used to adjust and control the rotating gear. After a certain amount of residue is collected inside the dust collecting box, the rotating gear is pushed to rotate. The bottom of the dust collecting box is supported by a bending spring. When the rotating gear and the rotating rod are rotated under force, the bending spring is compressed and deformed. The dust collecting box can rotate together with the rotating rod to dump the residue collected inside downward and make it fall into the discharge channel. The residues are gathered together, which is convenient for the staff to handle them uniformly and prevent the residue inside the dust collecting box from accumulating too much and spilling outward for a period of time. The dumping treatment method is simpler and does not require frequent manual treatment.

[0040] To sum up, by combining the flipping unloading mechanism with the cleaning and anti-sticking mechanism, the rotating wheel rotates with the rotating rod, and the rotating wheel corresponds to the position of the incomplete gear. When the rotating mold is flipped for unloading, the hydraulic telescopic rod also drives the shaping plate to rise to a certain height, and the arc-shaped driving protrusion rotates and presses on the arc-shaped contact block, so that the elastic long plate and the arc-shaped contact block deflect and deform downward, and press on the control button, thereby controlling the start of the drive motor, so that the cleaning of the bottom end of the shaping plate corresponds to the unloading process of the rotating mold, and the control method is simpler, and the existing power structure is used to control the start of the drive motor to prevent control deviation.

The guide plate 602 and the moving cross bar 603 are slidably connected by the sliding groove and the slider 616. The driving motor 611 drives the bidirectional screw rod 610 to rotate, so that the two moving blocks 612 move along the installation frame 609, and the two ends of the driving rod 614 are respectively connected to the positioning vertical rods 615. The rod 613 and the connecting vertical rod 615 are rotatably connected, and the driving rod 614 will push the moving crossbar 603 forward and slide along the guide plate 602. The cleaning scraper 604 will be close to the bottom end of the shaping plate 4 to scrape off the concrete residue adhering to the bottom thereof. The scraped residue will directly fall into the dust collecting box 607, so that the bottom end of the shaping plate 4 remains clean and flat, and the residue is uniformly collected without falling and scattering everywhere. In addition, the bottom end of the shaping plate 4 is cleaned after each pressing and shaping is completed to prevent residue from adhering to the bottom thereof, which may cause quality problems of the concrete slab prepared by subsequent pressing.

[0077] A support vertical plate 617 is fixedly installed at one end of the bottom of the cleaning scraper 604, and a bending spring 618 is fixedly connected to the middle of the support vertical plate 617 at an equal distance.

The driving rack 621 is used to adjust the rotating gear 619. The whole control, after a certain amount of residue is collected inside the dust box 607, the rotating gear 619 is pushed to rotate, and the bottom of the dust box 607 is supported by the bending spring 618. When the rotating gear 619 and the rotating rod 606 are rotated under force, the bending spring 618 is compressed and deformed, and the dust box 607 can rotate together with the rotating rod 606, and the residue collected inside it is dumped downward, so that it falls into the discharge channel 608. The residues are gathered together, which is convenient for the staff to handle them uniformly, and prevent the residues in the dust box 607 from accumulating too much and spilling outwards after a period of time. The dumping treatment method is simpler and does not require frequent manual treatment;

[0078] A rotating wheel 622 is fixedly installed at one end of the rotating rod 507, and an arc-shaped driving protrusion 623 is installed on the edge of the rotating wheel 622. An elastic long plate 624 is fixedly installed at one end of the middle part of the support frame 501, and an arc-shaped contact block 625 is fixedly connected to the end of the elastic long plate 624. A fixed long plate 626 is fixedly installed at one end of the support frame 501 below the elastic long plate 624, and a control button 627 is fixedly installed on the top of one end of the fixed long plate 626. The rotating wheel 622 and the elastic long plate 624 are located on the same vertical plane, and a gap is left between the bottom end of the rotating wheel 622 and the top end of the arc-shaped contact block 625. The arc-shaped contact block 625 is located just above the control button 627, and the signal output end of the control button 627 is connected to the driving The signal input end of the driving motor 611 is connected, and the rotating wheel 622 rotates with the rotating rod 507. The rotating wheel 622 corresponds to the position of the incomplete gear 508. When the rotating mold 502 is flipped over for unloading, the hydraulic telescopic rod 3 also drives the shaping plate 4 to rise to a certain height. The arc-shaped driving protrusion 623 rotates and presses on the arc-shaped contact block 625, so that the elastic long plate 624 and the arc-shaped contact block 625 deflect and deform downward, and press on the control button 627, thereby controlling the start of the driving motor 611, so that the cleaning of the bottom end of the shaping plate 4 corresponds to the unloading process of the rotating mold 502. The control method is simpler, and the existing power structure is used to control the start of the driving motor 611 to prevent control deviation.

[0079] The working principle and use process of the present invention are as follows: first, steel slag is mixed into concrete raw materials and stirred to make them fully mixed, which is used to prepare permeable concrete road slab raw materials. The staff injects the concrete raw materials mixed with steel slag into the rotating mold 502, and the hydraulic telescopic rod 3 extends downward, and the shaping plate 4 will descend and press on the top of the rotating mold 502 to pressurize and shape the injected concrete. The heating plate 503 will also generate heat to accelerate the solidification of the concrete. At the same time, the rotating motor 506 drives the rotating rod 507 to rotate, and the incomplete gear 508 and the eccentric wheel 509 rotate at the same time. At this time, the incomplete gear 508 is not engaged with the rotating gear 504, and the part of the eccentric wheel 509 close to the center of the circle is above the lifting rod 515 and is not in contact with the lifting rod 515. The concrete is pressurized and heat-insulated for a period of time and then formed. The hydraulic telescopic rod 3 contracts, driving the shaping plate 4 to rise and move away from the rotating mold 502.

[0080] Then, the part of the eccentric wheel 509 away from the center rotates downward and fits with the lifting rod 515. When it continues to rotate, it presses down the lifting rod 515, compressing the extrusion spring 514, causing the lifting rod 515 and the guide round rod 513 to descend, and the top of the embedding block 516 moves out of the positioning groove 511, and the positioning block 510 is no longer limited. At this time, the incomplete gear 508 rotates and meshes with the rotating gear 504, driving the rotating gear 504 and the rotating mold 502 to rotate together. The number of teeth on the edge of the rotating gear 504 is twice the number of teeth on the edge of the incomplete gear 508, and then the incomplete gear 508 drives the rotating gear 504 to rotate 180 degrees. After the rotating mold 502 flips 180 degrees, The formed concrete slab is facing downward, the top material cylinder 523 is vertically upward, and the hydraulic adjustment rod 517 is extended upward to adjust the height of the buffer material receiving plate 521 to make it close to the rotating mold 502. When the concrete is solidified and formed, it will stick to the inner wall of the rotating mold 502. The hydraulic telescopic rod 3 is extended downward again, and the shaping plate 4 is lowered and presses down the top material cylinder 523. The top material cylinder 523 is lowered along the limit frame 522, and the formed concrete slab will be pushed out of the rotating mold 502, so that it falls downward. The concrete slab will directly fall on the buffer material receiving plate 521. The hydraulic telescopic rod 3 is contracted to drive the shaping plate 4 to rise until the bottom end of the shaping plate 4 is flush with the top end of the cleaning scraper 604.

[0081] The buffer connecting plate 521 and the buffer spring 520 provide buffer protection for the falling concrete slab and absorb the impact force of its falling. The concrete slab's own gravity will press it down, the buffer spring 520 will be compressed, and the buffer connecting plate 521 will be pressed down. The height of each rise of the buffer connecting plate 521 is consistent. The standard concrete slab weight will press the buffer connecting plate 521 down to a certain height, so that its bottom end will contact the pressure sensor 529, and the pressure sensor 529 will feel its pressure. If the prepared concrete slab is lighter than the standard weight, that is, the buffer connecting plate 521 cannot contact the pressure sensor 529, and no pressure value is felt, it means that the weight of the prepared concrete slab is unqualified. If the buffer connecting plate 521 drops too much, the pressure sensor 529 will be squeezed, and the elastic airbag 527 will be affected. When the pressure is deformed, the pressure sensor 529 feels that the pressure exceeds the standard value, and the weight of the concrete slab prepared on the surface is too heavy and unqualified. The pressure sensor 529 is used to monitor different batches of concrete slabs. When the detection value is unqualified, the information will be directly transmitted to the alarm 530 to remind the staff, and the elastic airbag 527 buffers and protects the pressure sensor 529. When the concrete slab falls on the buffer receiving plate 521, there will be an impact force, causing the buffer receiving plate 521 to drop rapidly. At this time, it will contact the pressure sensor 529. Through the deformation of the elastic airbag 527, the position of the pressure sensor 529 will drop rapidly, which will reduce the impact force on the pressure sensor 529 and prevent it from being damaged by the impact. The staff can remove the concrete slab on the buffer receiving plate 521.

[0082] When the concrete slab is unloaded, the incomplete gear 508 and the eccentric wheel 509 continue to rotate. After the rotating mold 502 rotates 180 degrees, the incomplete gear 508 is no longer in mesh with the rotating gear 504. The position of the eccentric wheel 509 away from the center of the circle is no longer in contact with the lifting rod 515. The lifting rod 515 is no longer squeezed, and the squeezing spring 514 is reset and extended to lift the lifting rod 515 and the embedding block 516. The embedding block 516 will be embedded in the positioning groove 511 to limit the positioning block 510 and the rotating gear 504, so that the rotating mold 502 no longer rotates and shakes. When the rotating rod 507 rotates, the rotating wheel 622 also rotates synchronously, and the arc-shaped driving protrusion 623 rotates to the bottom, contacts and presses the arc-shaped contact block 625. The elastic long plate 624 is deformed and bent downward, and touches the control button 627 to start the driving motor 611.

[0083] Then, the driving motor 611 will drive the two-way screw rod 610 to rotate, and the two moving blocks 612 will move along the installation frame 609, gradually approaching the middle of the installation frame 609, and the two ends of the driving rod 614 will be rotatably connected with the positioning vertical rod 613 and the connecting vertical rod 615 respectively. When the moving block 612 and the positioning vertical rod 613 move, the position of the driving rod 614 changes, and the other end will push the moving cross bar 603 through the connecting vertical rod 615 to make it slide along the guide plate 602, and the slider 616 will slide inside the guide plate 602, and then the cleaning scraper 604 will move to the bottom of the shaping plate 4, and the top of the cleaning scraper 604 will contact the bottom of the shaping plate 4. When the shaping plate 4 presses the concrete, a small amount of concrete will adhere to its bottom end and form residue after solidification. The cleaning scraper 604 will continue to move, and the residue at the bottom of the shaping plate 4 will be removed to keep it clean. The scraped residue will fall into the dust collecting box 607.

[0084] After the cleaning scraper 604 moves forward a certain distance and cleans the bottom end of the shaping pressure plate 4, the driving motor 611 drives the bidirectional screw rod 610 to rotate in the opposite direction, so that the two moving blocks 612 move away from each other, and the driving rod 614 will pull the moving cross bar 603 backward, so that the cleaning scraper 604 gradually moves away from the shaping pressure plate 4. After moving backward to a certain distance, the dust collecting box 607 moves to the top of the discharge channel 608, and the rotating gear 619 will mesh with the driving rack 621 and continue to move. The driving rack 621 will cause the rotating gear 619 and the rotating rod 606 to rotate, and the dust collecting box 607 will also deflect downward with the rotating rod 606 to compress the bending spring 618. When the dust collecting box 607 is flipped, the residual dust collected inside it will pour down into the discharge channel 608. The discharge channel 608 can be cleaned regularly.
