Description

Technical Field

[0001] The utility model relates to the technical field of prestressed concrete production equipment, in particular to a prestressed concrete pipe pile mould. Background Art

[0002] Prestressed concrete pipe pile mold is a mold used to manufacture pipe piles. Pipe piles are a kind of prefabricated engineering piles, mainly used in pile foundation projects to improve the bearing capacity of foundations. The steel mold used to produce pipe piles is an upper mold and a lower mold. The two steel molds are screwed together. After the concrete is filled in the lower mold, the upper mold is covered and locked with bolts. This production process is called "pipe pile mold closing". At present, the bolt locking process in the pipe pile mold closing process is completed manually. Since there are many bolts involved in the mold closing process, the bolts need to be frequently tightened or loosened manually during the merging or separation of the upper mold and the lower mold, which results in a large workload, low tightening efficiency, and is time-consuming and labor-intensive.

[0038] In the above embodiment, please refer to the attached Figure 2 Preferably, a hexagonal groove is provided at the bottom of the nut fixing seat 76 and the top of the bolt fixing seat 8, and a magnet 81 is provided in each hexagonal groove. The magnet 81 prevents the removed bolts 4 and nuts 41 from falling directly on the ground, making it easy to reuse.

[0039] In the above embodiment, the outer walls of the upper and lower halves of the screw adjustment rod 66 have opposite external threads. The rotation of the screw adjustment rod 66 can drive the upper adjustment nut 67 and the lower adjustment nut 68 to move in opposite directions, thereby realizing precise control of the lifting and lowering movements of the first mounting plate 64 and the second mounting plate 65.

[0040] In the above embodiment, please refer to the attached Figure 2 The electric push rod 52, the second servo motor 71, and the first servo motor 91 are all existing commercially available devices and are controlled by the control system.

[0041] It can be seen from the above technical solution that when in use, the lower mold body 2 and the upper mold body 3 are hoisted and aligned together by the crane, and then adjusted along the longitudinal direction so that each group of bolts 4 and nuts 41 correspond to the horizontal position of each bolt disassembly and assembly mechanism respectively. Then, the controller controls each group of bolt disassembly and assembly mechanisms to tighten the corresponding bolts 4 at the same time. First, the guide plate 53 is driven to move in the slide groove 511 by the electric push rod 52, and the support column 61 moves inward until the nut fixing seat 76 is located directly above the nut 41, and then the first servo motor 91 drives the first bevel gear The rotation of 92 drives the second bevel gear 93 to rotate, and the rotation of the second bevel gear 93 drives the screw adjusting rod 66 to rotate clockwise. The rotation of the screw adjusting rod 66 drives the first mounting plate 64 and the second mounting plate 65 to move spirally toward the middle of the screw adjusting rod 66. At the same time, the bolt fixing seat 8 moves upward to support and clamp the hexagonal head of the main bolt 4, and the nut fixing seat 76 moves downward so that the nut 41 is completely embedded in the nut fixing seat 76. Then the first servo motor 91 stops working, and the controller starts the second servo motor 71. The second servo motor 71 drives the active pulley 73 to rotate. The V-belt 72 drives the driven pulley 74 to rotate, and the driven pulley 74 rotates to drive the lifting shaft 77 to rotate. The lifting shaft 77 drives the nut fixing seat 76 to rotate. The rotation of the nut fixing seat 76 drives the nut 41 to rotate downward on the screw rod of the bolt 4. The bolt 4 is relatively stationary in the bolt fixing seat 8 through its head. The bolt 4 moves downward to vertically fasten the lower mold body 2 and the upper mold body 3. When the fastening work is completed, the first servo motor 91 drives the first bevel gear 92 to rotate, driving the second bevel gear 93 to rotate. The rotation of the second bevel gear 93 drives the screw adjustment screw The section rod 66 rotates counterclockwise, causing the screw adjusting rod 66 to rotate and drive the first mounting plate 64 and the second mounting plate 65 to move spirally toward the two ends of the screw adjusting rod 66, and the nut fixing seat 76 moves upward to disengage from the nut 41, and the bolt fixing seat 8 moves downward to disengage from the head of the bolt 4. Then, the controller controls the electric push rod 52 to extend, driving the guide plate 53 to move in the slide groove 511, and the support column 61 moves outward, away from the lower mold body 2 and the upper mold body 3, thus completing the one-time bolt tightening work of the mold. If you need to loosen the bolts on the mold, just repeat the above steps.
