Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of floating gantry ships, and in particular relates to a floating gantry ship used for drilling and piling operations. Background Technology
[0002] In infrastructure construction such as water conservancy projects, port construction, bridge foundation construction, and offshore wind power, pile foundations are widely used as an important foundation type in various projects. Drilling and driving piles is a common construction method in pile foundation construction, which mainly involves driving piles into the ground using equipment such as impact drills or vibratory hammers. In offshore drilling and driving pile operations, the floating gantry vessel, as a key platform supporting the operating equipment, directly affects the accuracy and safety of the operation. In existing technologies, floating gantry vessels used for drilling and driving piles often employ a combination of multiple floating bodies to construct the operating platform, adapting to the needs of different operating ranges.
[0003] However, the existing floating assemblies lack sufficient overall structural strength, and the lack of coordinated reinforcement design for the lateral and longitudinal connections makes the assembled platform prone to overall swaying in complex aquatic environments. This not only reduces the positioning accuracy of drilling and piling operations and increases operational errors, but also may lead to risks such as equipment tipping and personnel safety hazards due to platform instability, making it difficult to meet the requirements for efficient and safe underwater drilling and piling operations.
[0004] To address these issues, we provide a floating gantry vessel for drilling and piling operations. Utility Model Content
[0005] The purpose of this utility model is to provide a floating gantry for drilling and piling operations. By using a limiting beam, the limiting beam is inserted into the positioning block. With the alignment and fixation of the first and second mounting plates, several floats can be combined laterally, providing an integrated basic structure for the device. The positioning plates at both ends can fit against the sides of the positioning block to restrict lateral movement. The central reinforcing frame has reinforcing rods arranged in a triangular combination. Utilizing the stability of the triangle, the structural strength of the limiting beam itself is significantly improved. This solves the problem of insufficient overall structural strength of existing float combinations and the lack of coordinated reinforcement design between the lateral and longitudinal connections, which makes the combined platform prone to overall swaying in complex aquatic environments.

[0007] Several positioning blocks are fixed on the upper surface of the float, and a first mounting plate is fixed on the top of the positioning blocks;
[0008] The positioning block has a first limiting groove on its side;
[0009] The positioning block contains a limiting beam, and both ends of the limiting beam are fixed with positioning plates.
[0010] The top of the limiting beam is fixed with several second mounting plates, and the surfaces of the first mounting plate and the second mounting plates are all opened with mounting holes.

Specific Implementation Example 1
[0044] Please see Figure 1-9This utility model is a floating gantry for drilling and piling operations, including a float 1, a bracket 2 fixed to the top of the float 1; several positioning blocks 3 fixed to the upper surface of the float 1, a first mounting plate 4 fixed to the top of the positioning blocks 3; a first limiting groove 5 opened on the side of the positioning blocks 3; a limiting beam 6 placed inside the positioning blocks 3, with positioning plates 7 fixed to both ends of the limiting beam 6; several second mounting plates 8 fixed to the top of the limiting beam 6, with mounting holes 9 opened on the surfaces of the first mounting plate 4 and the second mounting plates 8; several second limiting grooves 10 opened on one side of the limiting beam 6; a bearing 11 fixed to one side of the limiting beam 6, a transmission rod 12 fixed to the inner ring of the bearing 11, a threaded rod 13 fixed to one end of the transmission rod 12; a threaded pipe 14 threadedly connected to the outer side of the threaded rod 13, a connecting plate 15 fixed to the outer ring of the threaded pipe 14, a limiting plate 16 fixed to one side of the connecting plate 15; the limiting plate 16 passes through the first limiting groove 5 and the second limiting groove 10.
[0045] Specifically, a slider 17 is fixed to the bottom of the connecting plate 15, and several grooves 18 are fixed to the upper surface of the float 1.
[0046] Furthermore, the slider 17 has a "T" shaped structure and is slidably connected to the inner wall of the slide groove 18; a reinforcing frame 19 is fixed in the center of the limiting beam 6, and several reinforcing rods 20 are fixed inside the reinforcing frame 19; the several reinforcing rods 20 are arranged in a triangular combination.
[0047] The operation process in this embodiment is as follows: When it is necessary to achieve lateral connection and fixation of multiple floats, align the two ends of the limiting beam 6 with the positioning blocks 3 on the upper surface of the adjacent float 1, and slowly insert it into the positioning blocks 3 to ensure that the positioning plates 7 at both ends of the limiting beam 6 are in contact with the sides of the positioning blocks 3, thus restricting the lateral movement of the limiting beam 6. Adjust the position of the limiting beam 6 so that the first mounting plate 4 on the top of the positioning block 3 is completely aligned with the second mounting plate 8 on the top of the limiting beam 6. At this time, the mounting holes 9 on the surfaces of the two mounting plates coincide. Use bolts to pass through the... Tighten the mounting holes 9 and nuts to fix the limiting beam 6 and positioning block 3, thereby fixing the adjacent float 1. Rotate the threaded rod 13, which rotates smoothly through the support of the bearing 11. Since the threaded rod 13 is threadedly connected to the threaded tube 14, and the bottom of the threaded tube 14 slides along the groove 18 on the float 1 via the "T"-shaped slider 17 connected by the connecting plate 15, the threaded tube 14 will move towards the limiting beam 6 until the limiting plate 16 on one side of the connecting plate 15 completely penetrates the positioning block 3. The first limiting groove 5 and the second limiting groove 10 of the limiting beam 6 are connected. At this time, the limiting plate 16 simultaneously locks the positioning block 3 and the limiting beam 6, further enhancing the stability of the lateral connection. The float 1 is shaken to confirm that the limiting beam 6 is not loose and that the limiting plate 16 is tightly fitted with the first and second limiting grooves. The triangular reinforcing rod 20 enhances the overall strength of the limiting beam 6. By inserting the limiting beam 6 into the positioning block 3 and coordinating the alignment and fixation of the first mounting plate 4 and the second mounting plate 8, several floats 1 can be laterally combined to provide an integrated basic structure for the device. The positioning plates 7 at both ends can fit against the sides of the positioning block 3 to restrict their own lateral movement. The central reinforcing frame 19 is equipped with reinforcing rods 20 arranged in a triangular combination. Utilizing the stability of the triangle, the structural strength of the limiting beam 6 itself is significantly improved, and it can better withstand the external force during lateral connection. In conjunction with the limiting plate 16 being inserted into the first limiting groove 5 and the second limiting groove 10, the connection with the positioning block 3 is further locked to prevent loosening and enhance the overall stability of the floats after lateral combination. Specific Implementation Example 2
[0049] Please see Figure 6-9 Based on the first specific embodiment, a reinforcing shell 21 is fixed on both sides of the top of the float 1, and a reinforcing block 22 is movably connected to the inner wall of the reinforcing shell 21; a reinforcing plate 23 is fixed on the top of the reinforcing block 22.
[0050] Specifically, the outer wall of the reinforcing shell 21 has several first limiting holes 24, and the outer side of the reinforcing block 22 has several second limiting holes 25; the first limiting holes 24 correspond to the second limiting holes 25.
[0051] Furthermore, an extension plate 26 is fixed to the bottom of the reinforcing plate 23, and support plates 27 are fixed to both sides of the extension plate 26; the support plates 27 have a triangular structure.
[0052] The operation process of this embodiment is as follows: When it is necessary to longitudinally assemble the floats, for the floats 1 that need to be longitudinally connected, align the reinforcing block 22 at the bottom of the reinforcing plate 23 with the reinforcing shells 21 on both sides of the top of the float 1, and slowly insert it into the interior of the reinforcing shell 21; according to the longitudinal connection length requirements, adjust the depth of the reinforcing block 22 inserted into the reinforcing shell 21 so that the first limiting hole 24 on the outer wall of the reinforcing shell 21 is aligned with the second limiting hole 25 on the outer side of the reinforcing block 22, and pass the limiting pin through the aligned first limiting hole 24 and second limiting hole 25 to complete the fixation of the reinforcing block 22 and the reinforcing shell 21. At this time, the reinforcing plate 23 spans the adjacent longitudinal floats 1 to achieve longitudinal connection, and the reinforcement is confirmed. The extension plate 26 at the bottom of plate 23 is in close contact with the surface of float 1, and the triangular support plates 27 on both sides of the extension plate 26 are in close contact with the sides of float 1, further enhancing the load-bearing capacity and stability of the longitudinal connection. By inserting the reinforcing block 22 on one side of the reinforcing plate 23 into the reinforcing shell 21 at the top of float 1, and cooperating with the first limiting hole 24 of the reinforcing shell 21 and the second limiting hole 25 of the reinforcing block 22 to fix it, the longitudinal float 1 can be stably connected, enhancing the integrity of the longitudinal combination of multiple floats, providing a more reliable support foundation for the entire floating gantry, ensuring the stability of the platform during the drilling and piling operation, and reducing the safety risks caused by unstable connection.
