Description

Technical Field

[0001] This utility model relates to the field of underwater pile foundation construction technology, and in particular to a steel casing positioning guide frame. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the construction of underwater pile foundations, the accurate positioning and installation of large-diameter steel casings are crucial to ensuring the quality of the pile foundations and the safety of construction.

[0004] Traditional methods for positioning steel casings often require large lifting equipment and complex positioning devices, which are not only cumbersome to operate and inefficient, but also increase construction costs. In addition, due to the special nature of the aquatic environment, traditional positioning methods often face great difficulties in adjusting the position of steel casings, making it difficult to meet the requirements of high-precision positioning. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a steel casing positioning guide frame, thereby improving construction efficiency and positioning accuracy.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a steel casing positioning guide frame, comprising:

[0007] A support frame is installed on the pile foundation platform. The support frame includes two crossbeams and two longitudinal beams that are detachably connected to the two crossbeams and located between the two crossbeams. An installation hole for placing a steel casing is formed between the two crossbeams and the two longitudinal beams.

[0008] A guide frame, comprising a plurality of frame bodies detachably connected to a support frame and inserted into mounting holes, wherein at least one guide sleeve is provided between the plurality of frame bodies, and the guide sleeve has a guide hole for inserting a steel protective sleeve.

[0009] Multiple positioning bolts are arranged in a ring and threaded onto the guide sleeve, with one end inserted into the guide hole, allowing them to move towards or away from the center of the guide sleeve.

[0010] At least one synchronous adjustment component is provided on each guide sleeve, which can simultaneously drive each positioning bolt to move toward or away from the center of the guide sleeve.

[0011] Furthermore, the frame includes a vertical I-beam inserted into the mounting hole, and a horizontal I-beam detachably connected to the support frame is provided on the vertical I-beam. An inclined reinforcing I-beam is provided between the vertical I-beam and the horizontal I-beam.

[0012] Furthermore, the synchronous adjustment component includes multiple driven bevel gears rotatably mounted on the guide sleeve and located in the guide hole. The multiple driven bevel gears are respectively sleeved on each positioning bolt. Each driven bevel gear is provided with a protrusion that inserts into the corresponding positioning bolt. The positioning bolt is provided with a sliding groove for the protrusion to slide. When the positioning bolt rotates, it can move towards or away from the center of the guide sleeve and can drive the driven bevel gears to rotate synchronously through the protrusion.

[0013] The synchronous adjustment component also includes an active bevel gear ring sleeved inside the corresponding guide sleeve and located at the top of the driven bevel gear and meshing with each driven bevel gear. The active bevel gear ring can rotate around the axis of the guide sleeve and can move up and down.

[0014] Furthermore, the active bevel gear ring is provided with a positioning ring that abuts against the inner wall of the guide sleeve.

[0015] Furthermore, at least two handles located on the top of the guide sleeve are rotatably provided on the active bevel gear ring. Each handle is provided with a top support block that rotates with the handle and abuts against the top of the guide sleeve. When the bottom end of the top support block abuts against the top of the guide sleeve, the active bevel gear ring meshes with each driven bevel gear. When the top support block flips so that its top end abuts against the top of the guide sleeve, the active bevel gear ring separates from each driven bevel gear.

[0016] The beneficial effects of this utility model are reflected in:

[0017] This invention ensures the stability of the entire positioning guide frame by fixing the support frame to the water-based pile foundation platform. While the support frame itself is a fixed structure, its detachable design with the guide frame allows for easy disassembly and movement when not in use or when position adjustments are needed. The guide sleeve, with its guide hole matching the steel casing's shape and size, ensures accurate insertion. Furthermore, the guide sleeve is equipped with multiple positioning bolts, allowing for fine-tuning of the steel casing in both horizontal and vertical directions by adjusting their position and tightness, ensuring precise positioning. The use of synchronous adjustment components allows for unified adjustment of the positioning bolts during initial adjustment, followed by independent adjustment of individual bolts based on specific conditions, further improving construction efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-4 This utility model discloses a steel casing positioning guide frame, comprising:

[0029] Support frame 1 is set on the pile foundation platform. Support frame 1 includes two cross beams 11 and two longitudinal beams 12 that are detachably connected to the two cross beams 11 and located between the two cross beams 11. The two cross beams 11 and the two longitudinal beams 12 form an installation hole for placing the steel casing.

[0030] The guide frame 2 includes multiple frame bodies 21 that are detachably connected to the support frame 1 and inserted into the mounting holes. At least one guide sleeve 22 is provided between the multiple frame bodies 21. The guide sleeve 22 has a guide hole for inserting a steel sleeve.

[0031] Multiple positioning bolts 3 are arranged in a ring and threadedly connected to the guide sleeve 22, with one end inserted into the guide hole, and can move towards or away from the center of the guide sleeve 22.

[0032] At least one synchronous adjustment component 4 is provided on each guide sleeve 22, which can simultaneously drive each positioning bolt 3 to move toward or away from the center of the guide sleeve 22.

[0033] This utility model ensures the stability of the entire positioning guide frame by fixing the support frame 1 to the water-based pile foundation platform. The support frame 1 itself is a fixed structure, but its detachable design with the guide frame 2 facilitates disassembly and movement when not in use or when position adjustment is required. The guide sleeve 22, with its guide hole shape and size matching the steel casing, ensures accurate insertion of the steel casing. Furthermore, the guide sleeve 22 is equipped with multiple positioning bolts 3, allowing for fine-tuning of the steel casing in both horizontal and vertical directions by adjusting their position and tightness, ensuring precise positioning. The synchronous adjustment component 4 allows for unified adjustment of the positioning bolts 3 during initial adjustment, followed by independent adjustment of the respective positioning bolts 3 according to specific circumstances, further improving construction efficiency.

[0034] In practice, when there is only one guide sleeve 22, the horizontal position of the steel casing after insertion can be changed by adjusting the length of the positioning bolts 3 at each point in the guide hole. When there are multiple guide sleeves 22, the verticality of the steel casing in the guide hole can be adjusted by simultaneously adjusting the position of the positioning bolts 3 on multiple guide sleeves 22. This adjustment mechanism enables the positioning guide frame to adapt to steel casings of different diameters and inclination angles, thus improving its versatility and adaptability.

[0035] In one embodiment, the frame 21 includes a vertical H-beam inserted into a mounting hole, a horizontal H-beam detachably connected to the support frame 1 on the vertical H-beam, and an inclined reinforcing H-beam between the vertical H-beam and the horizontal H-beam.

[0036] This design increases the stability of the frame 21, and because all components of the frame 21 are I-beams, the materials are readily available, the structure is simple, and the cost is low.

[0037] In practice, the bottom of the support frame 1 can be equipped with a floating device or fixed legs to adapt to the needs of different water depths and construction environments.

[0038] In one embodiment, the synchronous adjustment component 4 includes a plurality of driven bevel gears 41 rotatably mounted on the guide sleeve 22 and located in the guide hole. The plurality of driven bevel gears 41 are respectively sleeved on each positioning bolt 3. The driven bevel gears 41 are provided with protrusions that are inserted into the corresponding positioning bolts 3. The positioning bolts 3 are provided with sliding grooves for the protrusions to slide. When the positioning bolts 3 rotate, they can move toward or away from the center of the guide sleeve 22 and can drive the driven bevel gears 41 to rotate synchronously through the protrusions.

[0039] The synchronous adjustment component 4 also includes an active bevel gear ring 42 that is sleeved in the corresponding guide sleeve 22 and located on the top of the driven bevel gear 41 and meshes with each driven bevel gear 41. The active bevel gear ring 42 can rotate around the axis of the guide sleeve 22 and can move up and down.

[0040] This design allows the active bevel gear ring 42 to descend and mesh with the driven bevel gear 41, enabling the active bevel gear ring 42 to rotate synchronously with multiple driven bevel gears 41. Due to the protrusion, the positioning bolts 3 also rotate with the driven bevel gears 41. Since the positioning bolts 3 are threadedly connected to the guide sleeve 22, each positioning bolt 3 can move closer to or further away from the center of the guide sleeve 22. When it is not necessary to adjust the positioning bolts 3 synchronously, simply move the active bevel gear ring 42 upward to separate it from the driven bevel gears 41.

[0041] In one embodiment, the active bevel gear ring 42 is provided with a positioning ring 43 that abuts against the inner wall of the guide sleeve 22.

[0042] This design ensures that the active bevel gear ring 42 remains coaxial with the guide sleeve 22 during the up and down movement through the positioning ring 43, thereby improving the stability of use.

[0043] In one embodiment, at least two handles 44 located on the top of the guide sleeve 22 are rotatably disposed on the active bevel gear ring 42. Each handle 44 is provided with a top support block 45 that rotates with the handle 44 and abuts against the top of the guide sleeve 22. When the bottom end of the top support block 45 abuts against the top of the guide sleeve 22, the active bevel gear ring 42 meshes with each driven bevel gear 41. When the top support block 45 flips so that its top end abuts against the top of the guide sleeve 22, the active bevel gear ring 42 separates from each driven bevel gear 41.

[0044] This design allows the operator to rotate the active bevel gear ring 42 by holding the handle 44. By rotating the handle 44 and adjusting the positions of the two ends of the top support block 45, the operator can control whether the active bevel gear ring 42 meshes with the driven bevel gear 41, making it convenient for the operator to adjust the working state of the active bevel gear ring 42.

[0045] In practice, the guide sleeve 22 is provided with a slot for the top support block 45 to be inserted, so that when the top support block 45 is flipped so that its top end abuts against the top of the guide sleeve 22, it can be inserted into the slot, thus avoiding accidental contact that would cause the top support block 45 to flip again.

[0046] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0048] Additionally, "multiple" refers to two or more.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
