Description

Technical Field

[0001] This invention relates to the field of ship welding and repair technology, specifically to a welding and repair device for ship metal protective components. Background Technology

[0002] Marine metal guardrails are safety devices that absorb and mitigate external impacts, protecting the edges of a ship's hull. During normal navigation, scrapes and collisions are common occurrences, and marine metal guardrails, as protective devices for the ship's hull edges, are among the most vulnerable to such incidents. While minor scrapes to the hull edges can be repaired with simple paint touch-ups, damage to the marine metal guardrails, especially if within repairable limits, requires welding for repair.

[0003] Traditional welding and repair equipment for ship metal protective components lacks mobility and flexibility, making it difficult to quickly move to different working positions. The welding and repair structure cannot adapt to the needs of flexible movement, rotation, and angle flipping at different heights and horizontal directions, limiting its operating range and preventing it from optimally handling the complex structures of ship metal protective components, thus affecting welding accuracy and efficiency. Traditional equipment requires welding repair, rust removal, and dust removal to be performed in separate steps, resulting in cumbersome procedures and low efficiency. It is difficult to adjust the position of the grinding and rust removal mechanism and the annular suction structure according to the specific location and shape of the ship's metal protective components, affecting rust removal and dust removal effectiveness. Furthermore, it cannot comprehensively and efficiently collect fumes and dust, creating a poor working environment that can harm the health of operators. Therefore, corresponding technical solutions need to be designed to address these issues. Summary of the Invention

Power supply components provide stable power support for all critical components of the equipment, while also facilitating power connection and management for operators.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The mobile vehicle serves as the mobile base of the equipment. The push rod frame facilitates the operator to push the equipment to different working positions, improving the mobility and flexibility of the equipment. The welding control column set at the middle of the upper part of the mobile vehicle provides stable support and precise control for the welding repair structure. The lifting adjustment seat slidably connected in front of the welding control column and the welding repair structure connected by the front robotic arm, rotary arm and flipping arm can be precisely lifted and adjusted in the vertical direction, so that the welding repair structure can adapt to welding positions at different heights and achieve flexible movement and rotation in the horizontal direction, further expanding the operating range of the welding repair structure. It can be flipped within a certain angle range, so that the welding repair structure can be welded in the best posture, ensuring welding quality and better meeting the welding repair needs of complex structures of ship metal protection components, improving the accuracy and efficiency of welding.

[0016] (2) By setting up a rust and dust removal mechanism above the mobile vehicle body, the equipment can perform rust and dust removal operations in a timely and effective manner while completing welding repair work, avoiding the tedious process of traditional equipment having to perform different processes step by step, and greatly improving work efficiency. The electric telescopic device with a multi-position adjustment mechanism can move the end plate horizontally, thereby adjusting the lateral position of the grinding and rust removal mechanism and the annular suction structure; it can also extend and retract vertically to achieve precise adjustment of the grinding and rust removal mechanism and the annular suction structure. It can precisely adjust the position of the grinding and rust removal mechanism and the annular suction structure according to the specific position and shape of the ship's metal protective components, thus improving the effect of rust removal and dust removal. The ring-shaped design of the annular suction structure allows the suction range to cover the area around the welding repair area, forming a relatively enclosed suction space. During the welding repair process, the smoke and dust generated can be quickly sucked into the suction pipe by the suction head, and then enter the dust collection and purification mechanism through the ring plate for purification. This can collect smoke and dust more comprehensively and efficiently, effectively improving the working environment and protecting the health of operators. The grinding and rust removal mechanism drives the drive motor to rotate the drive shaft, which in turn rotates the fixed column and the grinding head, thus achieving grinding and rust removal on the metal surface. The position of the fixed column is further adjusted so that the grinding head can act more precisely on the parts that need rust removal, which can better meet the rust removal needs of the complex surfaces of ship metal protective components, and improve the quality and efficiency of rust removal. The dust collection and purification mechanism allows the suction hose to flexibly adjust its position as the welded repair structure moves, ensuring the continuity and stability of dust collection. The negative pressure generated by the fan can draw air out of the purification cylinder, allowing the suction hose to draw smoke and dust into the purification cylinder. The multi-layer filter screen can perform multi-stage filtration of the inhaled smoke and dust, improving the purification effect. Attached Figure Description

[0030] Working principle: The operator holds the push rod frame 11 and pushes the mobile vehicle 1 to the front of the ship's metal protective components; The lifting adjustment seat 22, robotic arm 23, rotary arm 24 and flipping arm 25 in front of the welding control column 2 are activated to enable the front components of the welding repair structure 26 and the rust removal and dust removal mechanism 3 to be lifted and adjusted vertically, move and rotate flexibly in the horizontal direction, expand the operating range, and flip within a certain angle range so that the front components of the welding repair structure 26 and the rust removal and dust removal mechanism 3 are aligned with the required operating position in the best posture. At the same time, the electric telescopic device 371 is activated to drive the telescopic rod 372 to extend and adjust, and the electric hydraulic device 38 is activated to drive the hydraulic rod 381 to extend and adjust, so that the end plate 37 is located in the side adjustment position of the tilting arm 25, and the grinding position is adjusted more precisely.

The electric push rod device 3061 is activated, which drives the extension plate 3063 and the fixing ring 3064 to move via the push rod 3062, thereby changing the spacing and making the grinding head 30 more suitable for the outer surface of the metal protective component. The position of the fixing column 304 is adjusted by the extension and retraction of the positive hydraulic support rod 307 and the reverse hydraulic support rod 308, so that the grinding head 30 installed at the lower end of the fixing column 304 is close to the surface of the metal protective component. The contact pressure and angle between the grinding head 30 and the metal surface are adjusted to grind and remove rust from the surface of the metal protective component. The fan 35 generates negative pressure, drawing air into the purification cylinder 31 through the adapter pipe 34. Under the action of negative pressure, the suction head 393 in the annular suction structure draws the dust and fumes generated during grinding into the suction pipe 392. The suction pipe 392 then transports the dust and fumes through the ring plate 391 to the suction hose 32. The dust and fumes entering the purification cylinder 31 undergo multi-stage filtration through filter plate 363, filter plate 364, and filter plate 365 to improve the purification effect. The filter element inside the purification cylinder 31 can be inspected and maintained periodically by opening the cover plate 311 through the handle 362. The lifting and adjusting seat 22, which is slidably connected in front of the welding control column 2, can be raised and lowered in the vertical direction according to the height of the welding position, so that the welding repair structure 26 reaches the appropriate height; the robotic arm 23 and the rotary arm 24 enable the welding repair structure 26 to move and rotate flexibly in the horizontal direction, expanding the operating range; the flipping arm 25 is used to flip the welding repair structure 26 within a certain angle range, so that the welding repair structure 26 is aligned with the welding position in the best posture; Initiate welding repair of structure 26 to perform welding repair on the ship's metal protective components.
