Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a stable underwater bored pile floating piling platform device. Background Art

[0002] In the construction of bored cast-in-place piles in water, traditional water construction platforms usually need to build a temporary bridge for construction, and then extend the water construction platform on the temporary bridge. This not only requires a large workload and a large amount of turnover materials, resulting in a long construction period and high cost, but also when the underwater geology is complex, it is difficult to drive steel pipe piles, which poses a safety hazard. Therefore, a floating piling platform has been developed. The buoyancy supports the platform body to float on the water surface, and combines anchoring, power drive and operating equipment to work together to realize the construction of pile foundations such as bored cast-in-place piles in water.

[0003] Existing floating piling platforms face significant stability challenges during actual operations. Construction equipment (such as excavators) must be moved to different locations on the platform (e.g., piling from the center to the edge). Their weight generates an eccentric torque that varies with position, causing the platform to tilt. This tilt not only affects construction accuracy (e.g., deviation in pile verticality), but can also cause equipment shaking, operator safety risks, and, in extreme cases, even platform rollover. Furthermore, the required load-bearing capacity of the floating piling platform varies depending on the weight of the construction equipment. Existing floating piling platforms are difficult to adjust to accommodate construction equipment of varying weights, resulting in certain limitations.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-10 The present invention provides a technical solution for a stable underwater bored cast-in-place pile floating piling platform device: a stable underwater bored cast-in-place pile floating piling platform device, comprising a box body 1, a box cover 101 welded to the top of the box body 1, the box body 1 and the box cover 101 are welded to form a closed space, so that the box body 1 can float on the water surface, and an excavator can be placed on the top of the box body 1 to operate on the water surface, a rotating disk 2 is provided inside the box body 1, the middle part of the bottom of the rotating disk 2 is rotatably connected to the middle part of the bottom wall of the box body 1 through a rotating shaft, a cross-shaped slide 3 is provided on the top of the rotating disk 2, and the four ends of the cross-shaped slide 3 are respectively fixedly connected to the four inner side walls of the box body 1;

[0034] A buoyancy adjustment assembly is provided on the top of the cross-shaped slide 3. The buoyancy adjustment assembly includes four units, each of which includes a moving block 4. The moving block 4 is slidably connected to the cross-shaped slide 3. A pushing frame 402 is fixedly installed on the side of the moving block 4. A floating box 403 is slidingly limited on one side of the pushing frame 402. Both ends of one side of the top of the floating box 403 are fixedly connected with an extrusion block 404. The four moving blocks 4 can be moved synchronously outward along the cross-shaped slide 3 at the top of the four cross-shaped slides 3, and the four floating boxes 403 can be driven to extend to the four sides of the box body 1 respectively, thereby increasing buoyancy and carrying heavier objects.

[0035] A weight balancing assembly is provided on the top of the moving block 4. The weight balancing assembly includes four units, each of which includes a counterweight 5. The counterweight 5 is made of lead, has high density and is compact, which saves the internal space of the box 1 and can achieve precise counterweighting in a limited space. The counterweight 5 is slidably connected to the moving block 4. An electric cylinder 501 and an oil tank 1 502 are provided on one side of the counterweight 5. One end of the electric cylinder 501 is embedded in one end of the moving block 4. The output end of the electric cylinder 501 is fixedly connected to one end of the oil tank 1 502. The internal limit sliding of the oil tank 1 502 is provided with a piston rod 1 503. The bottom of the moving block 4 is fixedly installed with an oil tank 2 504. The interior of the oil tank 2 504 The limited sliding has a piston rod 2 505. As the moving block 4 moves, the piston rod 2 505 continuously moves toward the inside of the oil tank 2 504, so that the oil inside the oil tank 2 504 continuously enters the inside of the oil tank 1 502, thereby continuously pushing the piston rod 1 503 toward the end away from the oil tank 1 502, increasing the extension length of the piston rod 1 503, and thus flexibly increasing the pushable distance of the electric cylinder 501. According to the position of the excavator on the top of the box body 1, the corresponding electric cylinder 501 is started in the opposite direction of the tilt direction of the box body 1. The electric cylinder 501 only needs to output a constant distance to quickly and accurately move the corresponding counterweight block 5 over a longer distance to maintain the balance of the box body 1.

[0036] As an embodiment of a stable underwater bored pile floating piling platform device of the present invention, the outside of the rotating shaft is fixedly connected to a gear 2 204, the inner bottom wall of the box body 1 is fixedly installed with a motor 202, the output end of the motor 202 is fixedly connected to a gear 1 203, the gear 1 203 is meshed with the gear 2 204, the rotating disk 2 is provided with a sliding track 201, the sliding track 201 is set to an arc-shaped inclined structure, the bottom of the moving block 4 is fixedly connected to a sliding block 401, the sliding block 401 is limited and slides in the sliding track 201, and the motor 202 is started. The output end of the motor 202 rotates to drive the gear 1 203 to rotate, and then drives the gear 2 204 and the rotating disk 2 to rotate. The four moving blocks 4 slide within the sliding track 201 along their respective sliding blocks 401, and then synchronously drive the four moving blocks 4 to move along their respective cross-shaped slides 3 in a direction away from the center of the circle, thereby synchronously and quickly extending the four floating boxes 403 and synchronously moving the positions of the four counterweights 5 toward the center of the circle, thereby expanding the pressing positions of the four counterweights 5 and adjusting the gravity distribution to keep the box body 1 stable in the water;

[0037] As an embodiment of a stable underwater bored pile floating piling platform device of the present invention, the oil tank 1 502 and the oil tank 2 504 are connected by a hose, so that the oil in the oil tank 2 504 can flow into the oil tank 1 502 through the hose;

[0038] As an implementation method of a stable underwater bored pile floating piling platform device of the present invention, a baffle 506 is provided at the bottom of the cross-shaped slide 3. During the movement of the oil tank 2 504, one end of the piston rod 1 503 will contact the baffle 506. During the continuous movement, the baffle 506 continuously squeezes the piston rod 2 505, thereby squeezing the piston rod 2 505 toward the inside of the oil tank 2 504, squeezing the oil inside the oil tank 2 504 into the piston rod 1 503.

[0039] As an implementation method of a stable underwater bored pile floating piling platform device of the present invention, an anti-skid plate 102 is fixed on the top of the box cover 101 by bolts, and an anti-skid plate 102 is provided on the top of the anti-skid plate 102. The anti-skid pattern on the top of the anti-skid plate 102 can increase the friction between people and machines and the top of the anti-skid plate 102, making it safer for robots and machines to walk and move on the top of the box body 1. The worn anti-skid plate 102 can be easily replaced in time through bolt fixation.

[0040] The specific implementation is as follows. When it is necessary to increase the load-bearing weight of the box body 1 during use, the motor 202 can be started. The output end of the motor 202 rotates to drive the gear 1 203 to rotate, and then drives the gear 2 204 and the rotating disk 2 to rotate. The four moving blocks 4 slide within the sliding track 201 along the sliding block 401, and then synchronously drive the four moving blocks 4 to move along their respective cross-shaped slideways 3 in a direction away from the center of the circle, and then synchronously and quickly extend the four floating boxes 403 to increase the contact volume with the water, thereby increasing the water displacement volume, increasing the buoyancy, and being able to carry heavier objects. In addition, the positions of the four counterweights 5 are synchronously moved to keep the box body 1 stable in the water.

[0041] At the same time, as the moving block 4 moves, the second piston rod 505 continuously moves toward the inside of the second oil tank 504, thereby causing the oil inside the second oil tank 504 to continuously enter the inside of the first oil tank 502, thereby continuously pushing the first piston rod 503 toward the end away from the first oil tank 502, increasing the extension length of the first piston rod 503, thereby flexibly increasing the pushable distance of the electric cylinder 501. According to the position of the excavator on the top of the box body 1, the corresponding electric cylinder 501 is activated in the opposite direction of the tilt direction of the box body 1. The electric cylinder 501 only needs to output a constant distance to quickly and accurately move the corresponding counterweight block 5 over a longer distance to maintain the balance of the box body 1;

[0042] As an embodiment of a stable underwater bored pile floating piling platform device of the present invention, the four side walls of the box body 1 are all provided with a box outlet 7, and both sides of the top wall of the box outlet 7 are fixedly connected with an extrusion block 2 405, one side of the extrusion block 2 405 is set to an inclined structure, and one side of the extrusion block 1 404 is set to an inclined structure with the same inclination as the extrusion block 2 405, and each side of the inner bottom wall of the box body 1 is provided with a support block 406, and the support block 406 is set to an inclined structure with the same inclination as the extrusion block 1 404, and the support block 406 supports the buoyancy box 403. When it is necessary to continuously increase the buoyancy of the box body 1, the buoyancy box 403 continuously moves toward the outside through the box outlet 7. When the extrusion block 1 404 contacts the extrusion block 2 405, the extrusion block 1 404 is squeezed obliquely downward. Since the pushing frame 402 and the buoyancy box 403 are movably limited and connected, the buoyancy box 403 can be continuously moved downward and moved along the inclined surface of the support block 406. The support block 406 always supports the buoyancy box 403. Since the inclinations of the inclined surfaces of the extrusion block 1 404, the extrusion block 2 405 and the support block 406 are consistent, the buoyancy box 403 can be continuously and stably moved downward in the process of extending outward, so that the buoyancy boxes 403 on the four sides contact the water surface, thereby increasing the contact volume of the box body 1 with the water surface and the extended volume of the box body 1, thereby continuously increasing the buoyancy of the box body 1, and can carry heavier objects.

[0043] As an embodiment of a stable underwater bored pile floating piling platform device of the present invention, the top of the buoyancy box 403 is slidingly connected with a water baffle 1 6, the top of the water baffle 1 6 is slidingly connected to the cavity of the top wall of the outlet hole 7, and the bottom of the buoyancy box 403 is slidingly connected with a water baffle 2 601, the bottom of the water baffle 2 601 is slidingly connected to the cavity of the bottom wall of the outlet hole 7. When the buoyancy box 403 is extended and moved downward, the water baffle 1 6 and the water baffle 2 601 move downward synchronously with the downward movement of the buoyancy box 403, maintaining the sealing of the outlet hole 7 and preventing water from entering the box body 1;

[0044] Working principle: When the load-bearing weight of the box body 1 needs to be increased, the motor 202 can be started. The rotation of the output end of the motor 202 can drive the gear 1 203 to rotate, and then drive the gear 2 204 and the rotating disk 2 to rotate. The four moving blocks 4 slide within the sliding track 201 along the sliding block 401, and then synchronously drive the four moving blocks 4 to move along their respective cross-shaped slides 3 in a direction away from the center of the circle, and then synchronously and quickly extend the four floating boxes 403, thereby increasing the buoyancy and carrying heavier objects. The positions of the four counterweights 5 are also moved synchronously to adjust the gravity distribution inside the box body 1.

[0045] At the same time, as the moving block 4 moves, the piston rod 2 505 continuously moves toward the inside of the oil tank 2 504, so that the oil inside the oil tank 2 504 continuously enters the inside of the oil tank 1 502, thereby continuously pushing the piston rod 1 503 toward the end away from the oil tank 1 502, increasing the extension length of the piston rod 1 503, and thus flexibly increasing the pushable distance of the electric cylinder 501. According to the position of the excavator on the top of the box body 1, the corresponding electric cylinder 501 is started in the opposite direction of the tilt direction of the box body 1. The electric cylinder 501 only needs to output a constant distance to quickly and accurately move the corresponding counterweight block 5 over a longer distance to maintain the balance of the box body 1.
