Description

Technical Field

[0001] This utility model belongs to the field of underwater construction technology, and in particular relates to a device for positioning, docking and alignment of underwater formwork and equipment. Background Technology

[0002] In the process of underwater formwork assembly and equipment installation, existing technologies generally rely on mechanical equipment hoisting and manual command to complete underwater operations. Although this method can improve construction efficiency to some extent, it faces a series of problems and technical challenges that urgently need to be solved in practical applications:

[0003] First, the latency of underwater signal transmission severely restricts the effectiveness of remote control and precise command. In underwater environments, especially in deep water, signal transmission is affected by various factors such as water pressure, salinity, and temperature, leading to signal attenuation, delay, or even interruption in wireless communication. This makes it difficult for command personnel to monitor the real-time status of equipment during hoisting operations, affecting the accuracy and safety of the operation.

[0004] Secondly, the precision of mechanical equipment adjustments is also a key challenge. In underwater operations, lifting equipment often faces the difficulty of making minute adjustments to its position and angle. These precision issues not only affect construction quality but can also pose potential safety risks. For example, the complexity of the underwater environment can lead to errors in the positioning and angle adjustment of the lifting equipment, resulting in inaccurate alignment of formwork or equipment and increasing the workload for subsequent debugging and correction.

[0005] Furthermore, the difficulty of manually moving formwork underwater is a significant problem in construction. Underwater, the activities of operators are limited by diving depth, narrow working space, and the influence of water currents. Especially in complex construction environments, manually moving formwork or other equipment is both time-consuming and labor-intensive, and errors are prone to occur during operation, leading to delays in work progress or even equipment damage.

[0006] Besides the challenges of assembling underwater templates, the positioning and docking of underwater equipment also present similar technical difficulties. Equipment needs to be precisely positioned, docked, and secured underwater; however, factors such as water flow, tidal changes, and insufficient underwater lighting make it difficult to guarantee positioning accuracy. Furthermore, current technologies typically rely on manual labor or simple mechanical devices for docking, which cannot achieve rapid and precise docking, significantly increasing the complexity and risk of the operation.

The other end of the upper horizontal segment 101 is a pointed end. Figure 3 , 4 As shown, the device for positioning and aligning underwater templates and equipment also includes a second reinforcing bar 3. The second reinforcing bar 3 is n-shaped, including a middle section and legs 302 symmetrically connected to both ends of the middle section.

[0036] 5) Let B be the vertex of the end of the first steel bar 1 flat section near the lower bend 102.

[0037] 6) Let the vertical projection length of point B and point C be y, and let the horizontal projection length of point A and point C be x.

[0038] 7) Let h1 be the vertical projection length of the second reinforcing bar 3 from the contact surface with the first reinforcing bar 1 to the surface furthest from the contact surface with the first reinforcing bar 1.

[0043] 7) Let h1 be the vertical projection length of the second reinforcing bar 3 from the contact surface with the first reinforcing bar 1 to the surface furthest from the contact surface with the first reinforcing bar 1.

[0044] The positional relationships and constraints defined above are as follows:

[0045] (1) The above device is only suitable for fine-tuning when aligning two templates. The conditions for fine-tuning are: Otherwise, a major adjustment is required first.

[0047] (3) y = t;

[0049] (5)h1=a+h=a1+h.

[0050] The working process of the above-mentioned device for positioning, docking, and alignment of underwater templates and equipment is as follows:

[0051] ① The first rebar 1 bend and support 2 form a leveling and positioning system for leveling and positioning formwork or equipment. When the tops of two adjacent formworks are not aligned, the operating structure is used to embed the flange of one formwork rib plate between the first rebar 1 bend and the lower horizontal section 104 of the first rebar 1. Support 2 acts on another formwork rib plate that is connected to this rib plate. The lower bend 102 of the first rebar 1 serves as the second support 2. The structure increases the stroke through the two supports 2. Personnel adjust the upper horizontal section 101 of the first rebar 1 to drive the lower horizontal section 104 of the first rebar 1 for fine adjustment, thereby driving the formwork for fine adjustment. When the second rebar 3 falls to the top surface of the steel plate of the formwork (taking the rib plate as a channel steel, i.e., the bottom surface of the flange of the channel steel welded to the steel plate), the two formworks are aligned and can be fixed.

[0052] ② The tip of the first reinforcing bar 1 forms a butt joint system. The tip of the first reinforcing bar 1 is inserted into the bolt hole of the two templates to temporarily connect and fix the two templates.

[0053] ③ The second reinforcing bar 3 and the groove 303 form a positioning system. When two adjacent templates are misaligned, the operating structure allows the template ribs to be embedded into the grooves 303 of the two side legs 302 respectively. Personnel operate the first reinforcing bar 1 to adjust left and right, which in turn drives the second reinforcing bar 3 to adjust left and right, thereby achieving the purpose of template alignment and bolt hole alignment.

[0054] The above-mentioned device has the following characteristics:

[0055] 1. Saves manpower and machinery. Conventional underwater docking and positioning methods for templates require a crane to lift the template for fine-tuning by divers, or manual handling. This tool eliminates the need for a crane for fine-tuning when connecting templates underwater, and cleverly utilizes the lever principle to make adjustments easier for personnel, allowing for operation by a single person.

[0056] 2. Simple structure and easy to manufacture. Steel bars are readily available materials on the construction site, and can be used simply by bending and welding according to project requirements. They are also easy to dispose of after use.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
