Description

Technical Field

[0001] The invention belongs to the technical field of material forming, and relates to the production of a module prefabricated plate, in particular to a mold for manufacturing a module prefabricated plate for magnetic levitation rail transportation. Background Art

[0002] my country's high-speed railway construction technology is becoming more and more perfect, but because the construction method is affected by technical factors such as air resistance, noise, vehicle-track friction, and vehicle-track vibration, it is difficult to achieve new breakthroughs. As the most advanced ground transportation technology in the world, the ultra-high-speed low-vacuum pipeline maglev transportation system has a strong industrial driving force. On the basis of traditional industries such as steel and infrastructure, it will also drive the development of a large number of "high-precision" industries such as power electronics, advanced manufacturing, artificial intelligence, and big data, providing new momentum for the high-quality development of my country's economy. The ultra-high-speed low-vacuum pipeline maglev transportation system uses superconducting magnetic levitation technology to reduce vehicle-track vibration and eliminate vehicle-track friction. By establishing a low-vacuum operating environment, it greatly reduces aerodynamic noise and air resistance. The superconducting synchronous linear motor technology realizes the externalization of the power system to obtain a larger payload and speed, and can achieve a "near-ground flight" with a maximum speed of 1000km / h.

[0003] During the construction of ultra-high-speed low-vacuum pipeline maglev transportation, electromagnetic coil plates need to be installed symmetrically on both sides of the track, and the electromagnetic coil plates are installed on the module prefabricated plates. The module prefabricated plates adopt reinforced concrete structure. The shape of the module prefabricated plates is as follows Figure 8 As shown, two groups of embedded threaded holes for connecting lifting equipment are provided on the top, and the number of embedded parts in each group of embedded threaded holes is 4. The top of the side wall of the module prefabricated plate is convex, and a number of grooves are evenly opened at the bottom of the side wall. The bottom of the grooves penetrates to the bottom end face of the module prefabricated plate, and four groups of embedded threaded holes for fixing electromagnetic coils are provided on the side wall. The number of embedded parts in the two middle groups of embedded threaded holes is the same, both are 8, and the number of embedded parts in the two groups of embedded threaded holes on both sides is the same, both are 4. Since the precise positioning of the module prefabricated plate determines the running posture of the vehicle body, the installation accuracy of its multiple embedded threaded holes is particularly important. The shapes of the above embedded parts are as follows: Fig. 9 As shown, only the top hole portion is exposed on the surface of the module prefabricated board, and the rest of the portion is buried in the module prefabricated board.

[0004] At present, module prefabricated panels are cast by molds. During the casting process, embedded parts (embedded threaded holes) are not easy to be positioned and are prone to displacement. When pouring concrete in the mold cavity, the presence of embedded parts and steel bars can easily lead to uneven distribution of poured concrete, resulting in a rough surface or hollowing inside the finished product. At the same time, since the finished module prefabricated panels are large and have irregular surface structures, the existing molds are very inconvenient when demolding the module prefabricated panels, and the module prefabricated panels are easily damaged. Summary of the invention

[0031] The mold lower cover structure C is slidably connected to the four third support rods 3 through four third guide cylinders 53 , and the third guide cylinders 53 are fixedly connected to the side wall of the support plate 28 through the second connecting plate 54 .

[0032] The top surface of the top plate 2 is provided with an opening for the second embedded part insertion mechanism D to move up and down; the first hydraulic cylinder 7, the second hydraulic cylinder 22, the third hydraulic cylinder 26, the fourth hydraulic cylinder 27, the fifth hydraulic cylinder 33, the sixth hydraulic cylinder 39 and the seventh hydraulic cylinder 50 are respectively connected to the external hydraulic station pipeline through a conduit. The vibrator 14 is electrically connected to the external power supply through a wire.

[0033] When the mold of the present invention is used, firstly, the telescopic end of the third hydraulic cylinder 26 is controlled to extend, and the support plate 28 is raised to be close to the bottom of the mold cavity 4. At this time, the blocking plate 29 at the bottom of the mold cavity is inserted into the mold cavity 4 to completely block the bottom opening of the mold cavity 4. Subsequently, the embedded parts are installed on the second embedded part insertion mechanism D and the first embedded part insertion mechanism E. When the embedded parts are installed on the first embedded part insertion mechanism E, the embedded parts are fixed to the end of the first cylinder 47 by the first hexagon socket screw 48. At this time, the embedded parts are tightly attached to the end of the first cylinder 47; similarly, when the embedded parts are installed on the second embedded part insertion mechanism D, the embedded parts are fixed to the end of the first cylinder 47 by the second hexagon socket screw 21 It is fixed to the end of the second cylinder 20, at which time the embedded part fits tightly against the end of the second cylinder 20; then, the telescopic end of the seventh hydraulic cylinder 50 is controlled to retract, and the first embedded part insertion mechanism E is moved toward the mold cavity 4. As the telescopic end of the seventh hydraulic cylinder 50 retracts, the embedded part is inserted into the mold cavity 4 through the first guide cylinder 40, until the telescopic end of the seventh hydraulic cylinder 50 retracts to the maximum extent, the first cylinder 47 is inserted into the first guide cylinder 40 to completely block the first guide cylinder 40, and at the same time, the end of the first cylinder 47 is aligned with the inner wall of the mold cavity 4. At this time, the embedded part installed on the end of the first cylinder 47 is just completely inside the mold cavity 4.

[0034] Next, concrete is injected into the mold cavity 4, and then the telescopic end of the second hydraulic cylinder 22 is controlled to retract to the maximum extent, the second embedded part insertion mechanism D moves downward, and the embedded part fixed on the end of the second cylinder 20 passes through the second guide cylinder 16 and moves to the bottom of the second pressure plate 5, and the bottom end of the second cylinder 20 is flush with the bottom surface of the second pressure plate 5. At the same time, the second cylinder 20 is inserted into the second guide cylinder 16 to completely block the second guide cylinder 16. At this time, the telescopic end of the fourth hydraulic cylinder 27 is controlled to extend, so that the mold cover structure B moves downward as a whole, and the second pressure plate 5 and the L-shaped pressure plate 6 of the mold cover structure B are inserted into the mold cavity 4. The first pressure plate 11, the second pressure plate 5, and the pressure block 38 squeeze the concrete injected into the mold cavity 4, so that the concrete is evenly distributed in the mold cavity; at this time, the embedded parts inserted by the second embedded part insertion mechanism D are all buried in the concrete in the mold cavity 4, and the telescopic end of the first hydraulic cylinder 7 is controlled to retract, so that the first hydraulic cylinder 7 is no longer against the first pressure plate 11, and the vibration is started. The vibrator 14 can drive the first pressing plate 11 to vibrate up and down when the vibrator 14 is in operation. The spring 13 always gives the first pressing plate 11 a downward thrust through the second retaining ring 12 and the second guide rod 10. The telescopic end of the sixth hydraulic cylinder 39 is controlled to extend, and the pressing block 38 is used to squeeze the concrete in the mold cavity 4. When the concrete is squeezed by the pressing block 38, the concrete in the mold cavity 4 is affected by the squeezing force to push the first pressing plate 11. When the first pressing plate 11 is pushed, the spring 13 gives the concrete a reverse pressure. In this way, under the joint action of the vibrator 14 and the pressing block 38, the concrete in the mold cavity 4 is compressed and compacted, thereby effectively avoiding the uneven distribution of the concrete in the mold cavity 4 or the situation where there are bubbles inside. When the pressing block 38 presses out a groove with the same depth as the groove opened at the bottom of the side wall of the module prefabricated plate, the telescopic end of the sixth hydraulic cylinder 39 is stopped from extending further, and the vibrator 14 on the first pressing plate 11 stops running after running for 5-10 minutes, and then waits for the concrete in the mold cavity 4 to solidify and form.

[0035] After the concrete in the mold cavity is formed, the second hexagon socket screw 21 and the first hexagon socket screw 48 are loosened respectively, so that the embedded part embedded in the concrete is separated from the second hexagon socket screw 21 and the first hexagon socket screw 48, and the first arc-shaped stopper 46 can prevent the first hexagon socket screw 48 from escaping from the first cylinder 47, and the second arc-shaped stopper 19 can prevent the second hexagon socket screw 21 from escaping from the second cylinder 20, so as to avoid the loss of the second hexagon socket screw 21 and the first hexagon socket screw 48 after loosening; at this time, the telescopic end of the sixth hydraulic cylinder 39 is controlled to retract, and the pressing block 38 is retracted into the cover body 37; the telescopic end of the seventh hydraulic cylinder 50 is controlled to extend, and the first embedded part is inserted into the first cylinder 47 on the mechanism E from the first The first platform 30 and the second platform 35 are aligned with each other, and the telescopic end of the fifth hydraulic cylinder 33 is controlled to extend, and the module prefabricated plate on the bottom sealing plate 29 of the mold cavity is pushed onto the second platform 35 through the push plate 34, thereby completing the molding and demoulding of the module prefabricated plate.

[0036] In the process of making the module prefabricated plate of the mold of the present invention, the pressing block of the mold upper cover structure can not only shape the groove set on the module prefabricated plate for the concrete in the mold cavity, but also can squeeze the concrete, so that the concrete in the mold cavity bulges from below the first pressing plate, and the bulging part forms the bulging part on the module prefabricated plate. Due to the squeezing of the first pressing plate and the squeezing action of the pressing block, the concrete in the mold cavity is more compact, thereby effectively avoiding the uneven distribution of the concrete in the mold cavity and the generation of air bubbles inside. At the same time, through the setting of the vibrator on the first pressing plate, the concrete in the mold cavity can be further vibrated and squeezed, so that the concrete in the mold cavity is more compact. Moreover, through the detachable setting of the mold lower cover structure, the formed module prefabricated plate can be conveniently demolded from the mold cavity. Moreover, through the setting of the second embedded part insertion mechanism and the first embedded part insertion mechanism, the embedded parts are easy to install, and the embedded parts can be better positioned, which effectively prevents the embedded parts from being displaced during the concrete pouring process, and effectively improves the forming accuracy of the module prefabricated plate.
