Description

Technical Field

[0001] The present invention relates to the field of steel pipe pile guidance, in particular to a deepwater platform steel pipe pile positioning and guiding device. Background Art

[0002] The platform is an important temporary structure in bridge construction. Conventional platform steel pipe piles are directly driven in using a crawler crane and a vibratory hammer or a pile-driving ship. However, in deep water with strong current, this direct driving method will cause the steel pipe piles to deform significantly, making it difficult to meet the requirements of platform construction. Therefore, a positioning guide device is required during the steel pipe pile construction process to position the steel pipe piles.

[0003] Traditional guide systems typically involve constructing a small, simple platform near the location where steel pipe piles are to be driven, installing a positioning sleeve, and then dismantling the platform and re-installing it at the next location. Another approach involves constructing a larger, simple platform and hoisting the positioning sleeve to different locations to accommodate the different steel pipe pile positions. Both methods involve disassembly and assembly, making them time-consuming and labor-intensive. Due to the large number of steel pipe piles, the overall construction time is long.

DETAILED DESCRIPTION

[0032] like Figure 1-14 In the invention, a deep-water platform steel pipe pile positioning and guiding device includes multiple piles 1, and the upper ends of the multiple piles 1 are connected to fixed guide beams 2. There are at least two fixed guide beams 2, and each fixed guide beam 2 is arranged in parallel. A movable beam assembly is provided on the fixed guide beam 2, and a connected walking device 6 is provided below the movable beam assembly. The walking device 6 is slidably connected to the fixed guide beam 2. A steel pipe pile clamp 5 that can slide along the length direction of the second movable beam 4 is also provided on one side of the second movable beam 4. The steel pipe pile clamp 5 is used to position the steel pipe pile 10, and the moving direction of the walking device 6 is perpendicular to the moving direction of the steel pipe pile clamp 5.

[0033] Since the moving direction of the walking device 6 is perpendicular to the lateral moving direction of the steel pipe pile clamp 5, the steel pipe pile clamp 5 can move to multiple rows and columns and position itself at multiple steel pipe piles. The steel pipe pile clamp 5 opens and holds the steel pipe pile 10 to ensure that the steel pipe pile 10 is vertical. The inserting device inserts the upper end of the steel pipe pile 10 into the water bottom.

[0034] In the preferred solution, side edges 201 are provided on both sides of the fixed guide beam 2, and the movable beam assembly includes a first movable beam 3 and a second movable beam 4, which are slidably connected, and a walking device 6 is provided below both ends of the first movable beam 3 and the second movable beam 4. The walking device 6 includes a fixed frame 7, and a liftable telescopic frame 8 is provided at the lower end of the fixed frame 7. A rotatable walking wheel 801 and at least two lateral limiting wheels 802 are provided at the lower end of the telescopic frame 8. The walking wheel 801 rolls against the upper side of the fixed guide beam 2, and each lateral limiting wheel 802 rolls against the two sides of the fixed guide beam 2 respectively.

[0035] A moving beam travel drive motor 803 is provided on one side of the travel wheel 801. The moving beam travel drive motor 803 is preferably a servo or stepper motor with a brake, which has more accurate positioning, a locking function, and can record the travel distance.

[0036] An electric clamping device 9 can also be installed on one side of the walking device 6. When the walking device 6 reaches its position, the clamping device 9 clamps and fixes the guide beam 2 to achieve positioning.

[0037] A guide rail and slider structure and a second rack and pinion assembly 14 are installed between the first and second moving beams 3 and 4. Driven by a moving beam sliding drive motor 12, the first and second moving beams 3 and 4 slide relative to each other along their lengths. A first rack and pinion assembly 13 is installed on the side of the second moving beam 4 near the steel-pipe pile clamp 5. The rack and pinion are mounted on the second moving beam 4 and the steel-pipe pile clamp 5, respectively. A gear is connected to the shaft end of the clamp drive motor 11, driving the lateral movement of the steel-pipe pile clamp 5.

[0038] After the first movable beam 3 is lifted up, the two telescopic frames 8 of the second movable beam 4 are lifted up and separated from the fixed guide beam 2, and the second movable beam 4 is extended from the first movable beam 3, so that one end of the second movable beam 4 is close to the top of the adjacent fixed guide beam 2, and the telescopic frames 8 at both ends of the second movable beam 4 are lowered and abutted on the fixed guide beam 2, and the steel pipe pile clamp 5 moves to the vicinity of the adjacent new fixed guide beam 2, so that the center of gravity is shifted. Subsequently, the two telescopic frames 8 of the first movable beam 3 are lifted up and separated from the fixed guide beam 2, and the first movable beam 3 is moved horizontally to the side of the adjacent newly installed fixed guide beam 2, and the telescopic frames 8 at both ends of the first movable beam 3 are lowered again and abutted on the fixed guide beam 2, and the original fixed guide beam 2 on the outermost side is removed. The steel pipe pile clamp 5 can then work in the new area, and the old area can be poured with concrete simultaneously, thus saving construction time.

[0039] In a preferred embodiment, the telescopic frame 8 includes a first movable frame 804 and a second movable frame 816 that can move relative to each other. The first movable frame 804 is provided with a first wedge block 808, and the second movable frame 816 is provided with a second wedge block 815. The lateral limiting wheel 802 is connected to the first wedge block 808, and the second wedge block 815 squeezes the first wedge block 808 to make the lateral limiting wheel 802 move inward.

[0040] In the preferred embodiment, the walking wheel 801 is provided at the lower end of the middle of the first movable frame 804, the upper end of the first movable frame 804 is provided with at least two first guide rods 805, the end of the first guide rod 805 is provided with a stopper 806, the second movable frame 816 is provided with a lower end plate 812, the lower end plate 812 is slidably sleeved with the first guide rod 805, the lower end of the first movable frame 804 is provided with a downward extension plate 807, and a connecting side plate 809 is also provided. The lateral limiting wheel 802 is provided on the connecting side. At the lower end of plate 809, a second guide rod 810 is provided in the middle of the connecting side plate 809, and the second guide rod 810 is slidably connected to the downward extending plate 807. A second wedge block 815 is provided at the lower end of the lower end plate 812, and a first wedge block 808 is provided at the upper end of the connecting side plate 809. The wedge surfaces of the first wedge block 808 and the second wedge block 815 abut against each other. A first stop column 814 is provided at the lower end of the lower end plate 812, and the first stop column 814 is used to abut against the first movable frame 804.

[0041] The stopper 806 is used to prevent the first movable frame 804 from coming off the lower end plate 812. The second guide rod 810 is arranged transversely, and a stopper is also provided at the end to prevent it from coming off.

[0042] In a preferred solution, a return spring 811 is sleeved on the outer side of the second guide rod 810 , and two ends of the return spring 811 respectively abut against the downward extending plate 807 and the connecting side plate 809 .

[0043] As the second movable frame 816 moves downward, the second wedge block 815 begins to squeeze the first wedge block 808, causing the lateral limiting wheel 802 to move inward and abut against the side wall of the fixed guide beam 2. Simultaneously, the first movable frame 804 moves downward under its own weight, causing the running wheel 801 to abut against the upper side of the fixed guide beam 2, and the first stop post 814 to abut and press against the first movable frame 804. Due to the presence of the side edge 201, at this point, due to the elastic force of the return spring 811, the connecting side plate 809 naturally moves away from the lower extension plate 807, and the lateral limiting wheel 802 is in an open state. When the second movable frame 816 moves upward, the second guide rod 810 moves outward, and the lateral limiting wheel 802 breaks away from the side wall of the fixed guide beam 2 and gradually opens. When the first movable frame 804 is stopped by the stop plate 806, the second movable frame 816 lifts the first movable frame 804 and the components at its lower end, and the walking wheel 801 and the lateral limiting wheel 802 move upward as a whole until they are higher than the upper side of the fixed guide beam 2.

[0044] At this time, the moving beam sliding drive motor 12 works to drive the second moving beam 4 to move horizontally to the next position where it needs to be inserted.

[0045] In the preferred solution, the second movable frame 816 is provided with an upper end plate 813, the fixed frame 7 includes an upper fixed plate 701 and a lower fixed plate 702, a plurality of third guide rods 703 are provided between the upper fixed plate 701 and the lower fixed plate 702, the upper end plate 813 is slidably connected to the third guide rods 703, and is also provided with a lead screw 704, a nut is provided on the upper end plate 813, the nut is socketed with the lead screw 704, a lifting motor 705 is provided at one end of the lead screw 704, and the lead screw 704 drives the telescopic frame 8 to move up and down.

[0046] A second stop column 706 is provided on the lower fixed plate 702. When the walking wheel 801 and the lateral limiting wheel 802 abut against the fixed guide beam 2, the second stop column 706 just abuts against the upper end plate 813, so that the screw 704 and the lifting motor 705 do not have to bear the gravity of the entire mechanism.

[0047] In a preferred solution, the steel pipe pile clamp 5 includes a connecting seat 501 , on which clamping arm devices arranged opposite to each other are provided. The two clamping arm devices are movable relative to each other, and the clamping arm devices are provided with clamping arms 503 .

[0048] In the preferred embodiment, a plug-in bracket 502 is provided at one end of the clamping arm device, and the plug-in bracket 502 is slidably connected to the connecting seat 501. A rotatable worm gear 507 is provided in the connecting seat 501, and screw portions 505 with different thread rotation directions are provided at both ends of the worm gear 507. Each screw portion 505 is threadedly connected to each plug-in bracket 502. A rotatable worm 506 is also provided in the connecting seat 501, and the worm 506 is engaged with the worm gear 507.

[0049] In a preferred solution, at least two rotatable rollers 504 are provided on the inner side of each clamping arm 503 , and the rotation axes of the two rollers 504 are arranged at an angle, and the rollers 504 are used to abut against the outer wall of the steel pipe pile 10 .

[0050] In a preferred embodiment, a clamping arm driving motor 508 is provided at one end of the worm 506 .

[0051] Each clamping arm assembly can be equipped with two inserting brackets 502 and two corresponding worm gears 507.

The outer wall of the roller 504 can be curved or V-shaped, resting against the outer wall of the steel pipe pile 10.
