The implementation principle of the production equipment and the processing method of the ultra-high strength prestressed concrete pipe pile of the embodiment is as follows:
Weaving bearing steel bars 205 and stirrups 2051 into required shapes, coating release agents in the upper die 202 and the lower die 201, connecting two sides of a steel bar set with the sealing end covers 204, and fixedly connecting the sealing end covers 204 with two ends of the lower die 201 through connection; cement, sand, water, fly ash, mineral powder, silica fume and the like are added into a stirrer, meanwhile, a high-performance additive is added into the stirrer, after stirring is finished, raw materials are poured into the feeding box 301, an electronic valve 3031 at the tail end of the discharging pipe 303 is opened, and the whole device is restored to the initial position of FIG. 1.
The adjusting motor 1051 is started, the adjusting motor 1051 drives the terminal screw rod shaft 105 to rotate, screw threads formed on the surface of the screw rod shaft 105 are different, and the limiting rod 104 is further arranged to limit the two feeding boxes 301, so that the feeding boxes 301 on the two uniform-speed feeding units 300 are finally driven to move to two sides respectively.
When the feeding box 301 moves to two sides, the positioning gear 3023 on the surface of the feeding box 302 moves along the positioning rack 1033, so that the positioning gear 3023 can be driven to rotate, the partition 3021 at the tail end of the rotating shaft 3022 is driven to start rotating, the partition 3021 can intermittently feed the raw materials in the feeding box 301, the raw materials enter the lower die 201 from the discharging pipe 303, and the raw materials can be guaranteed to be filled in the lower die 201. After the filling is completed, the whole uniform feeding unit 300 is separated from the lower die 201, and the positioning gear 3023 at this time is moved to the inside of the locking groove 1034, so that the positioning gear 3023 stops rotating, the partition 3021 stops rotating synchronously, and the uniform feeding unit 300 is turned off for blanking.
When the feeding box 301 continuously moves to two sides, the push rod 3012 and the plunger 3011 at the tail end are pushed to the outside, the push rod 3012 and the positioning protrusion 4021 are finally rotated, the positioning protrusion 4021 is installed on the rotary table 402 and located at the eccentric position of the rotary table 402, the rotary table 402 is pushed to rotate, the transmission shaft 4022 in the center of the rotary table is driven to synchronously rotate, the transmission shaft 4022 rotates, the swing rod 403 at the bottom is driven to rotate downwards, the slide rod 4032 slides along the limiting plate 404, the whole pressing plate 401 is pushed to move downwards, and the upper die 202 at the bottom of the pressing plate 401 synchronously moves downwards, so that the upper die 202 and the lower die 201 are matched.
After the upper die 202 and the lower die 201 are contacted, the pressing plate 401 continues to move downwards, the vertical rod 502 pushing the bottom has a downward movement force, the torsion spring 5021 of the vertical rod 502 always has a force for driving the vertical rod 502 to rotate inwards, after the vertical rod 502 moves downwards, the synchronizing rod 5023 moves along the sliding groove 5011, finally, the vertical rod 502 can come out from the sliding groove 5012 through the sliding groove 5012, and the vertical rod 502 can rotate to be in a state of being attached to the bottom of the pressing plate 401 through the torsion spring 5021, so that the contact between the upper die 202 and the pressing plate 401 at the moment is avoided, and interference is avoided. Then, an operator needs to install the lower die 201 and the upper die 202 through bolts, and starts the driving motor 102, and drives the whole die plastic unit 200 to rotate through the driving motor 102, so that a centrifugal effect is generated, and further concrete inside the die forms a hollow cylindrical tubular pile, after the centrifugal effect is finished, the die is opened, the formed tubular pile is taken out, and in the rotating process of the die plastic unit 200, the guide rail 203 on the surface rolls on the guide wheel 2031, so that the guide supporting effect is realized.
