[0087] Example 3

[0088] Combining Example 1 and Example 2, the forming process of the UHPC cover plate is further described. Conventional UHPC cover plates require a conveying system, a production system, and a steam curing system. The conveying system includes: a mixing station and conveying equipment;

[0089] The production system includes: an out-of-mold production line, an in-mold production line, and a transverse movement mechanism; it also includes a palletizing and depalletizing machine for palletizing and depalletizing precast component molds or finished products between the out-of-mold production line, the in-mold production line, and the transverse movement mechanism;

[0090] The steam curing system includes: a steam curing kiln, an in-and-out kiln track, and a mother-and-child vehicle; the steam curing kiln is connected to the out-of-mold production line through the out-kiln track and its mother-and-child vehicle;

[0091] After pouring into the mold, it needs to be sent into a special vibration device for vibration forming, and then palletized and sent into the steam curing system. In this solution, raw materials such as fine sand, coarse sand, silica fume, cement, and additives are added to the mixing hopper 201 of the mixing component 2. After adding water and stirring, it flows into the transition bin 102, and the discharge baffle 214 is closed to continue the stirring work of the next hopper;

[0092] The mixed material after stirring is transported to the lower cover mortar component 6 through the pumping pump 103 and the flexible connecting pipe 104. Special steel fibers 801 are added to the vibrating disk 302 in the steel adding component 3. The steel fibers 801 are sent from the vibrating disk 302 into the guide groove 303, and finally transported to the special-shaped groove 510 of the cloth plate 504 through the distribution groove 304. The first limit 5110, the second limit 5111, and the third limit 5112 of the special-shaped groove 510 are electrified to prevent the steel fibers 801 from falling;

[0093] When the housing 701 is conveyed from the feeding conveyor belt 407 and moves to a stop above the pallet of the lifting oil cylinder 402 through the conveyor belt, at this time, the forward moving electric cylinder 601 moves the grouting nozzle 605 above the groove 7011, and the second lifting motor 602 controls the grouting nozzle 605 to move downward to the bottom of the groove 7011 for the first layer of covering grout. After covering the first layer of mixture, the second lifting motor 602 controls the grouting nozzle 605 to move upward and retract. The traversing electric cylinder 502 drives the lower distributing plate 504 to move above the groove 7011, and the first lifting motor 508 lowers the distributing plate 504 above the first layer of covering grout. At this time, the first limit switch 5110 and the second limit switch 5111 are energized, and the third limit switch 5112 is de-energized. The steel fibers 801 adsorbed by the electromagnet 511 fall above the first layer of covering grout. The distributing plate 504 moves upward and returns to its original position. After returning to its original position, the second rotating motor 501 rotates the distributing plate 504 to change the distributing direction of the steel fibers 801;

[0094] Repeat the above method to make the thickness of the mixture in the groove 7011 reach the final designed thickness, complete the pouring work of the cover plate. The distributing component 5 and the covering grout component 6 return to their original positions. Then, the vacuum suction cup 414 under the swinging motor 403 sucks up the cover plate 702 at the cover plate conveyor belt 408. During the rotation of the swinging motor 403, the moving motor 411 moves to the preset position, and the first rotating motor 412 rotates by a preset angle so that when the cover plate 702 rotates above the housing 701, it just aligns with the housing 701. At this time, the lifting oil cylinder 402 jacks up the housing 701 to engage with the cover plate 702, the vacuum suction cup 414 releases the cover plate 702, the swinging motor 403 rotates back to its original position, and the pallet of the lifting oil cylinder 402 returns to be flush with the discharging conveyor belt 406;

[0095] The housing 701 with the cover plate 702 covered is pushed by the pushing cylinder 416 onto the discharging conveyor belt 406 and sent to the next process. The next process is directly palletizing. After palletizing, it is sent to the initial curing chamber. After initial curing is completed, it is demolded and sent to the final curing chamber, and finally the finished product is produced. Compared with the traditional production of UHPC cover plates, the vibration process can be directly omitted;

[0096] After initial curing and final curing are completed, the staff can collect the curing parameters of each cover plate through the storage chip carried in the forming mold, including the temperature change during the curing process and the weight change of the cover plate itself. They can conduct key tests on the cover plates with unqualified parameters to prevent the outflow of defective products.

[0097] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations to the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
