[0002] During the construction of shipbuilding and offshore engineering projects, after the construction of sections and assemblies is completed, piers are used to raise the height for easy transportation. At the same time, there is usually a small amount of paint polishing and repairing, outfitting installation and port margin modification at the bottom of the section. At this stage, the sections have been placed on piers for transportation. The height of the piers is usually 2.5m. Personnel cannot carry out local engineering operations directly on the ground. In order to improve the convenience of construction personnel, reduce the repeated erection of scaffolding on site, and ensure safe working conditions, a movable work bed platform has been developed.

[0015] Compared with the prior art, the present invention provides a mobile work bed for assisting shipbuilding, which has the following beneficial effects: 1. The mobile work bed for assisting shipbuilding realizes the movement and positioning of the installation base plate through the cooperation of the universal pulley and the directional pulley. The stabilizing component in the stabilizing box of the installation base plate is used to assist in fixing the base plate during use to prevent it from being displaced due to external forces. The guide rod guides the sliding of the work plate. At the same time, the sliding rod enables the sliding plate to slide freely thereon. The limiting component arranged on one side of the sliding plate limits its position on the sliding rod to ensure that the sliding plate is stably controlled during operation. It can effectively improve the work efficiency in the shipbuilding process. The stabilizing component improves the safety during work and avoids the instability of the installation base plate due to external forces. The limiting component ensures that the sliding plate is accurately controlled in position, improves the accuracy and reliability of the operation, adapts to different working conditions, and has strong practicality and operability.

[0016] 2. The mobile work bed used to assist in shipbuilding can change the height of the lifting frame on the support plate by rotating the threaded rod. When the height of the lifting frame changes, it can push the work platform to change its height along the axis of the guide rod, thereby adapting to the needs of different heights and improving convenience during use.

[0017] 3. The mobile work bed for assisting shipbuilding, when the bottom plate is installed and used, by pulling the pulling block, the driving plate is driven to move to one side in the installation column. At this time, a gear meshing with the synchronous gear is provided on one side of the driving plate to drive the synchronous gear to rotate, thereby causing the rotating rod to rotate. When the rotating rod rotates, it can drive the rotating disk on its top to rotate at the same time. At this time, the limit rod can be guided by the guide groove to move synchronously along the guide groove track, thereby causing the sliding plate to move in the sliding seat. When the sliding plate moves, the deflection arm can be separated from the contact rods on both sides of the sliding seat. At this time, The deflection arm is made to rotate around the axis of the first connecting rod, so that the contact plate can be in contact with the ground. At the same time, the contact block contacts the limiting protrusion, so that the deflection angle of the contact plate can be limited, thereby avoiding damage caused by excessive deflection of the contact plate, effectively preventing excessive sliding of parts during movement, and improving safety and reliability. The vulcanized rubber pad at the bottom of the contact plate can effectively reduce shock and reduce the impact of external impact on the stabilizing component. It can effectively prevent unnecessary displacement of the bottom plate installed due to external force fluctuations during ship construction, ensuring that the stabilizing component always maintains stability and accuracy during use.

[0018] 4. The mobile work bed for assisting shipbuilding, when working on the work platform, when the sliding platform needs to slide on the sliding rod, by pulling the pulling rod, the rotating arm can be rotated around the axis of the second connecting rod, at this time, the pulling of the tension spring can be realized, and the limiting effect of the limiting rod can avoid the damage of the tension spring caused by the excessive deflection angle of the rotating arm. At the same time, the combination of the shock-absorbing plate and the rubber pad effectively reduces the external vibration and impact, and improves the stability and durability during use. At this time, the sliding plate can be pulled to slide on the sliding rod. When the sliding plate slides to the corresponding position, the pulling rod is released, and the rotating arm can be reset around the axis of the second connecting rod by the elastic force of the tension spring. At this time, the limiting plate can be brought into contact with the limiting groove on the sliding rod, thereby achieving the fixing effect of the sliding plate, thereby avoiding the sliding plate from being offset, ensuring the reliability and accuracy of the overall system, and by pulling the position of the sliding plate on the sliding rod, the different needs of the staff for standing and placing tools can be realized. The sliding plate is made of steel plate mesh material, and the accumulation of operating waste residues can be avoided at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle of the present invention: when in use, the movement and positioning of the installation base plate 1 are realized by the cooperation of the universal pulley 2 and the directional pulley 3. The stabilizing component in the stabilizing box 4 of the installation base plate 1 is used to assist in fixing the base plate 1 during use to prevent it from being displaced due to external forces. The guide rod 9 guides the sliding of the working plate 8. At the same time, the sliding rod 10 enables the sliding plate 26 to slide freely thereon.

At this time, the synchronous gear 13 is driven to rotate by a gear meshing with the synchronous gear 13 provided on one side of the driving plate 14, thereby causing the rotating rod 12 to rotate. When the rotating rod 12 rotates, it can drive the rotating disk 16 on its top to rotate at the same time. At this time, the limiting rod 20 can be guided by the guide groove 17 to move synchronously along the track of the guide groove 17, thereby causing the sliding plate 19 to move in the sliding seat 18. When the sliding plate 19 moves, the deflection arm 22 and the sliding seat 18 can be moved. The contact rods on both sides of the movable seat 18 are separated, and the deflection arm 22 can rotate around the axis of the first connecting rod 21 at this time, so that the contact plate 23 can be in contact with the ground.

The vulcanized rubber pad at the bottom of the contact plate 23 can effectively reduce shock and reduce the impact of external impact on the stabilizing component, which can effectively prevent the bottom plate 1 from being installed due to external force fluctuations during ship construction. Unnecessary displacement occurs. When working on the working platform 8, when the sliding plate 26 needs to slide on the sliding rod 10, by pulling the pulling rod 36, the rotating arm 30 can be rotated around the axis of the second connecting rod 29. At this time, the pulling of the tension spring 33 can be achieved. The limiting effect of the limiting rod 31 avoids damage to the tension spring 33 caused by excessive deflection angle of the rotating arm 30. At the same time, the combination of the shock absorbing plate 32 and the rubber pad effectively reduces external vibration and impact, thereby improving the stability and durability during use. At this time, the sliding plate 26 can be pulled to slide on the sliding rod 10. When After the sliding plate 26 slides to the corresponding position, the pulling rod 36 is released, and the elastic force of the tension spring 33 can reset the rotating arm 30 around the axis of the second connecting rod 29. At this time, the limiting plate 35 can contact the limiting groove 27 on the sliding rod 10, thereby achieving the fixing effect of the sliding plate 26, thereby avoiding the sliding plate 26 from deflecting, ensuring the reliability and accuracy of the overall system, and by pulling the position of the sliding plate 26 on the sliding rod 10, the different needs of the staff standing and placing tools are realized. The sliding plate 26 is made of steel mesh material to avoid the accumulation of waste residue during operation. ;
