Detailed Implementation

[0049] This invention designs a finely adjustable load-bearing beam bracket, which solves the difficulty of installing load-bearing beams under sea conditions and improves the reliability of installation.

[0050] In this embodiment, the load-bearing beam bracket is mainly divided into the following three components: a fixed lifting component 1, a support component 2, and an adjustment and control component 3. Figure 1 As shown.

[0051] The fixed lifting assembly 1 is used to fix the bracket after it has been moved into place, and provides support for other structures of the bracket, such as... Figure 2 As shown.

[0052] In one feasible implementation, when one person pushes the trolley handle 5, the bracket is moved closer to the load-bearing beam. Once the entire bracket is close to the installation position of the helicopter fuselage beam, the four swivel casters 4 of the base 8 of the fixed lifting assembly are secured. All four casters are dual-brake type, meaning that braking simultaneously locks both wheel rotation and swivel rotation. Depressing the brakes secures the base and prevents movement.

[0053] The Z-axis movement is achieved by rotating the handwheel 7 to drive the lead screw assembly 6 to move along the Z-axis, thereby raising or lowering the Z-axis slider 9 as a whole. After adjustment, the lead screw self-locks. The Z-axis slider 9 provides an installation interface for the adjustment mechanism 3, adopts a bolt connection, and features a modular design to enable disassembly, facilitating packaging and transportation.

[0054] Furthermore, the adjustment control component 3 is used for multi-dimensional adjustment of the bracket, and its specific components are as follows: Figure 3 As shown, the principle behind the adjustment function of each degree of freedom is as follows.

[0055] The adjusting component connecting plate 10 and the Z-axis slider 9 are connected by bolts, which facilitates disassembly and enables the Z-axis adjustment function of the adjusting mechanism.

[0056] Among them, the X-axis movement is adjusted by sliding the follower slider 19 on the X-axis slide rail 11. The adjusting rod 15 drives the follower slider 19 to move within the slide rail. The slider and the slide rail are fitted with a clearance, so the adjustment mechanism can be easily adjusted in the X-axis direction.

[0057] The Y-axis movement is adjusted by sliding the follower slider 19 on the Y-axis slide rail 12. The adjusting rod 15 drives the follower slider 19 to move within the slide rail. The slider and the slide rail are fitted with a clearance, which allows the adjustment mechanism to move easily in the Y-axis. Once the adjustment is complete, the mechanism can be locked by tightening the first locking handwheel 14.

[0058] The rotation around the Y direction is achieved by driving the single-ear assembly 13 to rotate the double-ear assembly 27 and the single-ear assembly 13 to rotate the adjustment joint 26 to rotate the axis. The double-ear assembly 27, the adjustment joint 26, and the adjustment rod 15 are a single unit with a rigid connection. The locking function can be achieved by tightening the second locking handwheel 16.

[0059] Among them, rotation around the X direction is achieved by driving the adjusting rod 15 to rotate in the X direction within the hole of the joint bearing 17. The adjusting rod, the joint bearing hole, and the follower slider hole are in clearance fit, thereby achieving clearance rotation within the follower slider 19, and locking is achieved by tightening the first locking handwheel 14.

[0060] Among them, rotation around the Z-axis is achieved by driving the adjusting rod 15 to rotate in the Z-axis within the hole of the spherical bearing 17. Within ±9°, the spherical bearing can be used as a ball bearing. When rotating around the Z-axis, the follower slider 19 follows with a large clearance in the adjusting slide rail 18, and can be locked by tightening the first locking handwheel 14.

[0061] The upper part of the single ear assembly 13 provides an installation interface for the three-dimensional support assembly 2. It adopts bolt connection, modular design, and can be disassembled, which is convenient for packaging and transportation.

[0062] In other embodiments of this application, the support component 2 is used for the structural support of the load-bearing beam, fits against the bracket, directly supports the bracket, and provides driving force through the handle. Its specific composition is as follows: Figure 4 As shown, the principle behind the precision fine-tuning function is as follows.

[0063] In this component, the front support plate 20 and the rear support plate 21 of the V-shaped support assembly 2 are connected by bolts using connecting angle brackets 25, allowing for the replacement of individual modules. The front and rear support plates are connected to the single-ear assembly 13 by bolts.

[0064] The support plate is equipped with simulated load connection hooks 22. The hooks are completely consistent with the load interface. The two hooks are pressed into the hanging hooks and locked, forming a reliable connection with the load hanging beam. During disassembly or installation, the load hanging bracket can be effectively prevented from sliding accidentally.

[0065] The dimensional support assembly 2 features an adjustment handle 24 that allows for precise fine-tuning in various directions with minimal force, providing driving force for the entire adjustment and control assembly. Rubber pads 23 are installed on the support plate to protect the composite material skin of the load-bearing beam from damage. Operators can freely adjust the movement in multiple dimensions by gripping the handle. Once adjusted, the first locking handwheel 14 and the second locking handwheel 16 can be locked, facilitating easy installation of the load-bearing beam.

[0066] It should be noted that the technical effects of this application are as follows:

[0067] Operability: The load-bearing beam can be precisely adjusted in multiple dimensions of displacement and angle by manually holding the handle, and the load-bearing beam can be precisely adjusted in the vertical top mounting by rotating the handwheel to drive the screw assembly.

[0068] Replaceability: This bracket adopts a modular design, and the components are easy to disassemble, install, and replace. The V-shaped support component is replaceable, and the support plate can be customized according to the shape of the hanging beam, thus meeting the positioning and fixing of various complex-shaped installation objects, and has strong adaptability;

[0069] Maintainability: The bracket requires only one person to operate. Key components utilize self-lubricating spherical bearings, resulting in low frictional resistance, minimal operating force, and easy one-handed operation with short adjustment times. This significantly improves operational efficiency and maintainability.

[0070] Safety: The use of casters makes it easy to adjust the initial position. After moving it into place, stepping on the wheel brakes will fix the base and prevent movement. After adjustment, the handwheel can be locked to lock the installation position, and there is a self-locking function in the Z direction. The load-bearing beam and bracket are connected stably and reliably, which improves the overall safety.

[0071] Reliability: Purely mechanical structure, installation is done entirely by manpower, requiring no electricity, hydraulic or other equipment, lightweight and highly reliable.

[0072] In summary, the shape-adjustable load-bearing beam bracket of the present invention enables precise 6-DOF fine-tuning and jacking installation of the load-bearing beam on the ship's deck. This bracket is easy to operate, has a short adjustment time, and is highly adaptable, significantly reducing the installation and positioning time of the load-bearing beam. The present invention improves the maintainability of the load-bearing beam under sea conditions and enhances the efficiency and reliability of installation work.
