Description

Technical Field

[0001] This invention relates to the field of ship welding, specifically a portable welding machine box for shipbuilding. Background Technology

[0002] Welding machines are electrical appliances that provide power with specific characteristics for welding. Welding is widely used in various industrial fields, such as aerospace, shipbuilding, automotive, and container manufacturing, due to its advantages of flexibility, simplicity, convenience, strength, reliability, and the ability to achieve strength comparable to the base material after welding. In shipyards and platform construction, welding equipment is used flexibly and quickly during the assembly and sectionalization of ships. Therefore, multiple welding machines are often combined within a welding machine housing for welding operations. On-site welding machine housings are often bulky, heavy, and difficult to move. Often, when shipyard or platform sections are hoisted into place, the welding equipment cannot be immediately positioned and requires the assistance of cranes or forklifts. However, due to the sometimes limited availability of cranes and forklifts on-site, the welding machine housing cannot be immediately positioned, resulting in wasted time for positioning, assembly, or welding, thus affecting the company's shipbuilding progress and schedule, leading to economic and time losses. Therefore, welding machine housings used in shipbuilding are typically mobile.

[0003] However, since ship welding requires multiple welding groups to work together, the entire welding machine box is quite heavy, and it is also quite difficult to move the entire box when it needs to be moved. Summary of the Invention

[0004] To address the existing problems, the present invention provides a movable welding machine box for shipbuilding, which, when used in conjunction with other devices, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A movable welding machine housing for shipbuilding includes a welding machine housing with universal casters mounted on its lower surface. An adjustment mechanism is located on one side of the lower end of the welding machine housing, and a movable support is located below the adjustment mechanism. The adjustment mechanism includes a lead screw fixing support and a directional lead screw. A directional pivot is connected between the movable support and the welding machine housing. A connecting crossbar is located on the inner side of the movable support at the lower end of the adjustment mechanism. A fixed lug is mounted on the upper surface of the connecting crossbar. A bottom connecting rod is located inside the fixed lug. A rotating lug is mounted on the lower surface of the bottom connecting rod. The rotating lug is connected to the fixed lug via a pivot. A ball bearing mounting seat is mounted at the lower end of the directional lead screw. Rotating balls are arranged in a circular array on the outer wall of the ball bearing mounting seat. A movable groove is formed inside the bottom connecting rod outside the ball bearing mounting seat. Fixed casters are mounted on the lower surface of the movable support at the end furthest from the directional pivot.

[0007] As a further embodiment of the present invention: a push-pull handle is installed above the adjustment mechanism on the side surface of the welding machine box, and a lifting lug is installed on the upper surface of the welding machine box.

[0008] As a further embodiment of the present invention: a heat dissipation window is installed on the side of the welding machine housing away from the adjustment mechanism, a rain cover is provided on the outer side of the heat dissipation window, a cover plate hanging ring is installed on the outer side wall of the rain cover, and a movable positioning hook is installed above the cover plate hanging ring on the side surface of the welding machine housing.

[0009] As a further embodiment of the present invention: a cabinet door panel is installed on one side of the welding machine box, and a welding torch conduit is installed on one side of the cabinet door panel.

[0010] As a further embodiment of the present invention: the directional lead screw is engaged with the lead screw fixed support, the ball bearing mounting seat is fixedly connected to the directional lead screw, and the rotating ball is movably connected to the ball bearing mounting seat.

[0011] As a further embodiment of the present invention: the rotating ear plate is movably connected to the fixed ear plate, the movable bracket is movably connected to the welding machine housing through the directional rotating shaft, the lead screw fixed support is fixedly connected to the welding machine housing, and the fixed roller is movably connected to the movable bracket.

[0012] As a further embodiment of the present invention: the ball bearing mounting base is movably connected to the movable groove via the rotating ball bearing, the fixed ear plate is fixedly connected to the connecting crossbeam, and the universal roller is movably connected to the welding machine housing.

[0013] As a further embodiment of the present invention: the push-pull handle is fixedly connected to the welding machine housing, and the lifting lug is fixedly connected to the welding machine housing.

[0014] As a further embodiment of the present invention: a movable shaft is connected between the rain cover and the welding machine box, the movable positioning hook is engaged with the cover hanging ring, and positioning hooks are arrayed above the movable positioning hook on the outer side of the welding machine box.

[0015] As a further embodiment of the present invention: the cabinet door panel is movably connected to the welding machine box, and the welding torch conduit is configured to pass through the cabinet door panel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When torque is applied to the entire adjusting screw, the rotating lug on the lower surface of the bottom connecting rod will move using the movable shaft and the fixed lug, so that the entire movable bracket can rotate with the welding machine box under the action of the adjusting shaft. The entire welding machine box will be placed at a certain tilt angle. Therefore, the welding machine box will have a downward moving force under the action of the component of gravity, which can facilitate the movement of the entire welding machine box.

[0018] 2. The rotating balls arranged in an array on the outer surface of the ball bearing mounting base will roll inside the movable groove opened inside the bottom connecting rod, thus ensuring the normal rotation of the directional screw. At the same time, the rotating ear plate and the fixed ear plate are in a movable setting, which can facilitate the overall movement of the directional screw.

[0019] 3. Push or pull the push-pull handle to control the movement of the welding machine box. The universal rollers on the lower surface of the welding machine box can facilitate the movement of the entire welding machine box and facilitate the change of the orientation of the entire device.

[0020] 4. By applying tension to the cover plate hanging ring on the outer surface of the rain cover, the rain cover rotates with the welding machine housing. After being engaged by the movable positioning hook and the cover plate hanging ring, the heat dissipation window can be used for heat dissipation. At the same time, the rain cover can prevent water from entering the welding machine housing when it rains. Attached Figure Description

[0030] like Figure 1-6As shown, this embodiment provides a movable welding machine box for shipbuilding, including a welding machine box 1. Universal casters 6 are mounted on the lower surface of the welding machine box 1 and are movably connected to it. An adjustment mechanism 4 is provided on one side of the lower end of the welding machine box 1. A movable support 5 is provided below the adjustment mechanism 4. The adjustment mechanism 4 includes a lead screw fixing support 401 and a directional lead screw 402. The directional lead screw 402 is engaged with the lead screw fixing support 401, and the lead screw fixing support 401 is fixedly connected to the welding machine box 1. A directional rotating shaft 501 connects the movable support 5 to the welding machine box 1, and the movable support 5 is movably connected to the welding machine box 1 via the directional rotating shaft 501. A connecting crossbeam 504 is provided on the inner side of the movable support 5 at the lower end of the adjustment mechanism 4. A fixed ear plate 503 is mounted on the upper surface of the connecting crossbeam 504 and is fixedly connected to the connecting crossbeam 504. The bottom connecting rod 403 is internally provided, and a rotating ear plate 407 is installed on the lower surface of the bottom connecting rod 403. The rotating ear plate 407 is connected to the fixed ear plate 503 by a rotating shaft. The rotating ear plate 407 and the fixed ear plate 503 are movably connected. A ball bearing mounting seat 404 is installed at the lower end of the adjusting screw 402. The ball bearing mounting seat 404 is fixedly connected to the adjusting screw 402. Rotating balls 405 are installed in a circular array on the outer side of the ball bearing mounting seat 404. The rotating balls 405 are movably connected to the ball bearing mounting seat 404. A movable groove 406 is opened inside the bottom connecting rod 403 on the outer side of the ball bearing mounting seat 404. The ball bearing mounting seat 404 is movably connected to the movable groove 406 through the rotating balls 405. A fixed roller 502 is installed on the lower surface of the movable bracket 5 at the end away from the adjusting shaft 501. The fixed roller 502 is movably connected to the movable bracket 5.

[0031] like Figure 2-4 As shown, in this embodiment, a push-pull handle 3 is installed above the adjustment mechanism 4 on the side surface of the welding machine box 1. The push-pull handle 3 is fixedly connected to the welding machine box 1. A lifting lug 2 is installed on the upper surface of the welding machine box 1. The lifting lug 2 is fixedly connected to the welding machine box 1. A heat dissipation window 10 is installed on the side of the welding machine box 1 away from the adjustment mechanism 4. A rain cover 9 is provided on the outer side of the heat dissipation window 10. A movable shaft is connected between the rain cover 9 and the welding machine box 1. A cover plate hanging ring 11 is installed on the outer wall of the rain cover 9. A movable positioning hook 12 is installed above the cover plate hanging ring 11 on the side surface of the welding machine box 1. The movable positioning hook 12 is engaged with the cover plate hanging ring 11. A positioning hook 8 is arranged in an array above the movable positioning hook 12 on the outer side of the welding machine box 1. A cabinet door panel 7 is installed on one side of the welding machine box 1. A welding torch cable tube 13 is installed on one side of the cabinet door panel 7. The welding torch cable tube 13 is connected to the cabinet door panel 7.

[0032] The working principle of this invention is as follows: During use, a forklift can be used in conjunction with the lifting lugs 2 on the upper surface of the welding machine housing 1 for movement. The welding equipment is stored inside the welding machine housing 1. The movement of the welding machine housing 1 is controlled by pushing or pulling the push-pull handle 3. Universal rollers 6 are provided on the lower surface of the welding machine housing 1 to facilitate the movement of the entire welding machine housing 1 and to facilitate changes in the orientation of the entire device. When there are many components inside the welding machine housing 1, resulting in a large self-weight of the entire device, pushing or pulling the welding machine housing 1 may become difficult. Therefore, the adjustment mechanism 4 controls the entire movable support. The height of component 5 changes to alter the overall tilt of the welding machine housing 1 for auxiliary movement. When torque is applied to the adjusting screw 402, it engages with the screw fixing support 401. During the rotation of the adjusting screw 402, the ball bearing mounting seat 404 at its lower end also rotates simultaneously. The rotating balls 405 arranged in an array on the outer surface of the ball bearing mounting seat 404 roll inside the movable groove 406 inside the bottom connecting rod 403, thus ensuring the normal rotation of the adjusting screw 402. Simultaneously, when the adjusting screw 402 pushes the bottom... When the connecting rod 403 is pushed downwards, the rotating lug 407 on the lower surface of the bottom connecting rod 403 moves using the movable shaft and the fixed lug 503. This allows the movable bracket 5 to rotate with the welding machine housing 1 under the action of the directional shaft 501, turning the entire movable bracket 5 towards the lower position of the welding machine housing 1. This allows the fixed roller 502 on the lower surface of the movable bracket 5 to contact the moving plane, and the universal roller 6 on the lower surface of the welding machine housing 1 near the movable bracket 5 will be suspended in the air. The entire placement of the welding machine housing 1 will be tilted to a certain extent. The angled design allows the welding machine housing 1 to move towards the lower end under the influence of gravity, facilitating its movement. When the entire device is in operation, the internal temperature rises. By applying a pulling force to the cover plate hanging ring 11 on the outer surface of the rain cover 9, the rain cover 9 rotates with the welding machine housing 1. After the movable positioning hook 12 and the cover plate hanging ring 11 are engaged, the heat dissipation window 10 can be used for heat dissipation. At the same time, the rain cover 9 can prevent water from entering the welding machine housing 1 during rainy weather. The positioning hook 8 can be used to hang the welding gun.
