Technical Field

[0001] The utility model relates to the technical field of concrete pipe pile construction, in particular to a concrete pipe pile connection construction device. Background Technology

[0002] Prestressed concrete pipe piles have been widely used in construction projects due to their advantages such as high single pile bearing capacity, high pile quality, and time saving. Prestressed concrete pipe piles are all produced in factories. Limited by equipment molds and production capacity, the length of a single section of the finished pipe pile is generally 7 to 15 meters. For special projects, such as the foundation of power transmission line towers in mountainous areas, if a large-diameter single pile foundation is used, the length of a single section of the pipe pile needs to be further reduced to facilitate the transportation and construction of the pipe piles in mountainous areas. In the construction process of prestressed concrete pipe piles, there is an inevitable problem of pile connection.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Combined with Figures 1-7 , a concrete pipe pile splicing construction device includes a positioning plate 1, a turning platform 2 and a fixed plate 7. A rotating shaft 3 is rotatably arranged between the positioning plate 1 and the turning platform 2. Support legs 4 are fixedly arranged at the bottoms of the positioning plate 1 and the turning platform 2. Moving wheels 5 are fixedly arranged at the bottoms of the support legs 4. The fixed plate 7 is fixedly arranged on the turning platform 2. Lifting lugs 8 are fixedly arranged at both ends of the turning platform 2 away from the fixed plate 7. Positioning holes 11 are opened on the positioning plate 1. Stop holes 74 are opened on the fixed plate 7. A sliding groove 75 communicating with the stop holes 74 is opened on the fixed plate 7. A stop baffle 73 is slidably connected in the sliding groove 75. A fixed bracket 71 is fixedly arranged on the fixed plate 7. A hydraulic push rod 72 is fixedly arranged on the fixed bracket 71. The hydraulic rod of the hydraulic push rod 72 is fixedly connected with the stop baffle 73. A pile splicing mechanism 6 is arranged on the turning platform 2.

[0026] Refer to Figures 3-5, it is further obtained that the pile splicing mechanism 6 includes a positioning table 601, on which a placing cushion plate 602 is fixedly arranged. A first groove 603 is formed at the upper end of the positioning table 601, and a second groove 619 communicating with the first groove 603 is formed at the lower end of the positioning table 601. A worm 604 is rotatably connected in the second groove 619, and a bidirectional lead screw 607 is rotatably connected in the first groove 603. A worm gear 608 meshing with the worm 604 is fixedly sleeved on the middle end of the bidirectional lead screw 607. Ball nuts 609 are threadedly connected to both ends of the bidirectional lead screw 607. A connecting plate 610 is fixedly arranged on the ball nut 609, and an arc-shaped clamping plate 611 is fixedly arranged on the connecting plate 610. An anti-slip sticker 612 is adhered inside the arc-shaped clamping plate 611. A first motor 605 is fixedly arranged at one end of the positioning table 601. One end of the worm 604 rotatably penetrates through the second groove 619, and a gear transmission group 606 is arranged for transmission between the rotating shaft of the first motor 605 and the worm 604.

[0027] Specifically, the device is moved to the pipe pile splicing position by the moving wheels 5, and the positioning holes 11 are coaxially arranged with the pile holes of the concrete pipe piles. At this time, the device is in the Figure 1 state. Then, the pipe pile to be spliced is placed on the placing cushion plate 602 on the positioning table 601, and one end of the pipe pile extends into the stop hole 74 of the fixing plate 7. Then, the first motor 605 is started. Driven by the gear transmission group 606, the worm 604 rotates. The worm 604 drives the meshing worm gear 608 to rotate, and the worm gear 608 drives the bidirectional lead screw 607 to rotate, so that the ball nuts 609 threadedly connected to both ends of the bidirectional lead screw 607 can drive the two connecting plates 610 and the arc-shaped clamping plates 611 to move towards each other, so that the two arc-shaped clamping plates 611 can tightly clamp the pipe pile. The anti-slip sticker 612 arranged inside the arc-shaped clamping plate 611 can improve the stability of the pipe pile. The hook of the crane is connected to the lifting lug 8 on the flipping table 2. Under the pulling of the crane, the flipping table 2 and the fixing plate 7 are rotated into the Figure 2 vertical state as shown, so that the fixed pipe pile is also rotated into the vertical state. The stop plate 73 in the stop hole 74 can stop and support the pipe pile when the pipe pile rotates, preventing the pipe pile from falling out of the stop hole 74 during the rotation process.

[0028] Refer to Figure 6, it is further obtained that the pile splicing mechanism 6 further includes two fixed sliders 613 fixedly connected to the bottom of the positioning table 601. Two chutes 614 adapted to the fixed sliders 613 are provided on the turning table 2. A lead screw 615 is rotatably connected in each of the two chutes 614. The fixed slider 613 is threadedly connected to the lead screw 615. A second motor 617 is fixedly arranged at the bottom end of the turning table 2. One end of each of the two lead screws 615 rotatably penetrates through the chute 614. A first belt transmission group 616 is arranged between the two lead screws 615. A second belt transmission group 618 is arranged between the second motor 617 and the lead screw 615 near the second motor 617.

[0029] Specifically, after the pipe pile is in a vertical state, the hydraulic push rod 72 drives the stop baffle 73 to contract and release the stop on the pipe pile. Then, the second motor 617 is controlled. Under the driving action of the second belt transmission group 618 and the first belt transmission group 616, the two lead screws 615 rotate, so that the fixed slider 613 threadedly connected to the lead screw 615 can drive the positioning table 601 to move, so that the pipe pile can move stably downward. The butt end of the pipe pile slowly passes through the stop hole 74 and is butted with the embedded pipe pile. After that, the pile splicing operation can be carried out. When the pile splicing is completed, the turning table 2 is reset by using a crane, and then the subsequent pile splicing operation can be carried out according to the above operation.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principle and spirit of the present invention.
