Description

Technical Field

[0001] This utility model relates to the field of mobile platform equipment technology, specifically to an adjustable steel structure mobile platform. Background Technology

[0002] A CO2 welding machine, commonly known as a carbon dioxide gas shielded welding machine, is a type of consumable electrode arc welding equipment that uses carbon dioxide (CO2) as the shielding gas. When welding at heights is required, the CO2 welding machine must be mounted on a steel structure platform for use.

[0003] An existing Chinese patent (authorization announcement number: CN214739747U) discloses an adjustable-height mobile construction platform for steel structures. It includes a workbench, a protective net, a lifting protective frame structure, adjusting bolts, a support sleeve, a telescopic support rod, an electric lifting frame structure, brake wheels, a crossbeam, a climbing ladder, a fixing sleeve, a triangular reinforcing plate, a fixed telescopic column, fixing bolts, and support pads. The protective net is welded to the upper left and right sides of the workbench; the lifting protective frame structure is installed on the upper outer side of the protective net. The beneficial effects of this invention are: the arrangement of a reduction motor, a drive gear, and a driven gear facilitates the upward movement of the support sleeve through the meshing between the drive gear and the driven gear, and the threaded connection between the driven gear and the telescopic support rod, thereby achieving automatic lifting and lowering of the workbench without the need for manual adjustment by the operator, thus reducing the labor intensity of the workers.

[0004] When using existing equipment with a CO2 welding machine for high-altitude welding, the welding machine needs to be moved manually and placed on the workbench. However, it is difficult to set up a conventional staircase between the existing workbench and the equipment. Instead, ladders such as handrails are often used. When moving the welding machine, it is difficult for personnel to climb the handrails because their hands are occupied, making the loading and unloading process very inconvenient. Utility Model Content

[0005] The purpose of this application is to solve the problem that when personnel move welding machines, their hands are occupied and it is difficult to climb the handrail ladder, which makes the loading and unloading process of welding very inconvenient. This application provides an adjustable steel structure mobile platform.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An adjustable steel structure mobile platform includes a base, a lifting platform mounted on the upper end of the base, a platform rotatably connected to the upper end of the lifting platform, a railing fixedly connected to the upper end of the platform, a door frame hinged to the end of the railing, several casters fixedly connected to the lower end of the base, a disassembly port opened at one end of the railing, an installation plate installed inside the platform, the diameter of the disassembly port being larger than that of the installation plate, an installation groove opened inside the installation plate, a push plate slidably connected within the installation groove, a buffer pad fixedly connected to the end of the installation plate, and a disassembly structure provided on the platform.

[0008] By adopting the above technical solution, when using this device to load a CO2 welding machine for high-altitude welding, the lifting platform is first lowered to lower the platform, and then the mounting plate is moved towards the disassembly port, so that the tail of the mounting plate moves to the edge of the disassembly port and the mounting plate rotates, so that the buffer pad contacts the ground and the mounting plate is tilted. Then the push plate is loosened, and the bottom of the CO2 welding machine is placed in the tilted mounting groove. Then the push plate is used to fix the CO2 welding machine. This allows the device to facilitate the disassembly, maintenance and repair of the welding machine during the auxiliary welding process, and makes the welding machine more stable when the platform moves, avoiding the inconvenience of manually moving the welding machine.

[0009] Furthermore, the disassembly structure includes a mounting motor fixedly connected inside the platform, an mounting screw fixedly connected to the output end of the mounting motor, the mounting screw being rotatably connected to the platform, a movable plate being threadedly connected to the outer surface of the mounting screw, and the movable plate being rotatably connected to the mounting plate inside.

[0010] By adopting the above technical solution, the installation motor is started to rotate the installation screw, so that the moving plate moves to the disassembly port. At this time, the installation plate is no longer resisted by the lifting platform. The installation plate rotates along the moving plate towards the ground. At this time, the buffer pad contacts the ground, so that the installation plate is tilted at an angle.

[0011] Furthermore, a guide column is fixedly connected inside the platform, and the outer surface of the guide column is slidably connected to the moving plate.

[0012] By adopting the above technical solution, the moving plate moves along the guide column, making the movement of the moving plate more stable.

[0013] Furthermore, an electric push rod is fixedly connected to the inner wall of the mounting groove, the end of the electric push rod is fixedly connected to the push plate, and anti-slip texture is provided on one side of the push plate.

[0014] By adopting the above technical solution, the electric actuator is activated to move the push plate away from the welding machine, allowing the welding machine to be removed and replaced.

[0015] Furthermore, a drive motor is fixedly connected to the upper end of the base, and a bidirectional screw is fixedly connected to the output end of the drive motor. The end of the bidirectional screw is rotatably connected to the base. Both ends of the bidirectional screw are threaded with threaded sleeves. A connecting rod is hinged to the upper end of the threaded sleeve. The middle parts of the two connecting rods are rotatably cross-connected through the same rotating shaft. A sliding sleeve is connected to the upper end of the connecting rod. A fixed column is fixedly connected to the lower end of the lifting platform. The sliding sleeve is slidably connected to the fixed column.

[0016] By adopting the above technical solution, the drive motor is started to drive the bidirectional screw to rotate, causing the threaded sleeve to move in opposite directions, which in turn drives the connecting rod to move. The upper end of the connecting rod drives the sliding sleeve to move, thereby adjusting the angle of the connecting rod to resist the lifting platform for lifting and lowering.

[0017] Furthermore, a telescopic column is fixedly connected to the upper end of the base, and the upper end of the telescopic column is fixedly connected to the lifting platform.

[0018] By adopting the above technical solution, adjusting the angle of the connecting rod causes the telescopic column to retract, thereby resisting the lifting platform to rise and fall.

[0019] Furthermore, a rotating motor is fixedly connected inside the lifting platform, a gear is fixedly connected to the output end of the rotating motor, and a gear ring is fixedly connected to the lower end of the platform, with the gear and gear ring meshing with each other.

[0020] By adopting the above technical solution, the rotating motor is started to drive the gear to rotate, and the gear drives the gear ring to rotate, so that the platform rotates accordingly. The height and angle of the platform can be easily adjusted, making the welding process more convenient.

[0021] Furthermore, a lifting ladder is fixedly connected to the lower end of the lifting platform, and a storage sleeve is fixedly connected to one end of the base. The shape of the storage sleeve is adapted to the lifting ladder. An anti-slip pad is fixedly connected to the lower end of the lifting ladder, and the lower surface of the anti-slip pad has anti-slip texture.

[0022] By adopting the above technical solution, when the lifting platform is raised or lowered, the lower end of the elevator also moves along the storage sleeve. The elevator can adapt to the current height when the lifting platform is raised or lowered, making it more stable for people to go up and down. As the lifting platform falls, the contact pad at the lower end of the elevator contacts the ground, which makes the device more stable when placed.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the CO2 welding machine needs to be disassembled, the lifting platform is first lowered, which causes the platform to descend. Then, the installation motor is started to rotate the installation screw, causing the moving plate to move along the guide column until the moving plate moves to the disassembly port. At this time, the installation plate is no longer resisted by the lifting platform, and the installation plate rotates towards the ground along the moving plate. At this time, the buffer pad contacts the ground, causing the installation plate to tilt at an angle. Then, the electric push rod is started to drive the push plate away from the welding machine, so that the welding machine can be removed for replacement. This device allows for convenient disassembly, avoiding the inconvenience of manually moving the welding machine. During the process of assisting the welding machine in welding, this device facilitates the disassembly, maintenance, and repair of the welding machine.

[0025] 2. In this application, when the platform position needs to be adjusted, the drive motor is first started to drive the bidirectional screw to rotate, causing the threaded sleeve to move in opposite directions, which in turn drives the connecting rod to move. The upper end of the connecting rod drives the sliding sleeve to move, thereby adjusting the angle of the connecting rod and causing the telescopic column to retract, thus resisting the lifting platform to rise and fall. Then, the rotary motor is started to drive the gear to rotate, which in turn drives the gear ring to rotate, causing the platform to rotate accordingly. This allows for convenient adjustment of the platform's height and angle, making the welding process more convenient. Attached Figure Description

[0033] The following will be based on the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Reference Figure 1 and Figure 4 This utility model provides a technical solution: an adjustable steel structure mobile platform, including a base 1, a lifting platform 15 installed on the upper end of the base 1, a platform 12 rotatably connected to the upper end of the lifting platform 15, a railing 13 fixedly connected to the upper end of the platform 12, a door frame 14 hinged to the end of the railing 13, a number of universal wheels 2 fixedly connected to the lower end of the base 1, a disassembly port opened at one end of the railing 13, an installation plate 17 installed inside the platform 12, the diameter of the disassembly port being larger than that of the installation plate 17, an installation groove opened inside the installation plate 17, a push plate 18 slidably connected in the installation groove, a buffer pad 16 fixedly connected to the end of the installation plate 17, and a disassembly structure provided on the platform 12.

[0035] When using this device to load a CO2 welding machine for high-altitude welding, first lower the lifting platform 15 to lower the platform 12. Then, move the mounting plate 17 towards the disassembly port, so that the tail of the mounting plate 17 moves to the edge of the disassembly port and rotates the mounting plate 17, so that the buffer pad 16 contacts the ground and the mounting plate 17 is tilted. Then, loosen the push plate 18, and then place the bottom of the CO2 welding machine into the tilted mounting groove. Then, fix the CO2 welding machine by the push plate 18. This device facilitates the disassembly, maintenance and repair of the welding machine during the auxiliary welding process, and makes the welding machine more stable when the platform 12 moves, avoiding the inconvenience of manually moving the welding machine.

[0036] Reference Figure 1 and Figure 4 , Figure 5The disassembly structure includes a mounting motor 27 fixedly connected inside the platform 12. A mounting screw 26 is fixedly connected to the output end of the mounting motor 27, and the mounting screw 26 is rotatably connected to the platform 12. A movable plate 25 is threadedly connected to the outer surface of the mounting screw 26, and the movable plate 25 is rotatably connected to the mounting plate 17 inside. A guide post 24 is fixedly connected inside the platform 12, and the outer surface of the guide post 24 is slidably connected to the movable plate 25. An electric push rod 23 is fixedly connected to the inner wall of the mounting groove, and the end of the electric push rod 23 is fixedly connected to a push plate 18. Anti-slip textures are provided on one side of the push plate 18.

[0037] When it is necessary to disassemble the CO2 welding machine installed in the mounting slot, first lower the lifting platform 15, which in turn lowers the platform 12. Then, start the mounting motor 27 to rotate the mounting screw 26, causing the moving plate 25 to move along the guide column 24 until the moving plate 25 moves to the disassembly port. At this time, the mounting plate 17 is no longer resisted by the lifting platform 15, and the mounting plate 17 rotates towards the ground along the moving plate 25. At this time, the buffer pad 16 contacts the ground, causing the mounting plate 17 to tilt at an angle. Then, start the electric push rod 23 to drive the push plate 18 away from the welding machine, so that the welding machine can be removed for replacement. This device can be easily disassembled, avoiding the inconvenience of manually moving the welding machine. During the process of assisting the welding machine in welding, this device can facilitate the disassembly, maintenance, and repair of the welding machine.

[0038] Reference Figure 2 and Figure 3 A drive motor 11 is fixedly connected to the upper end of the base 1. A bidirectional screw 3 is fixedly connected to the output end of the drive motor 11. The end of the bidirectional screw 3 is rotatably connected to the base 1. Threaded sleeves 7 are threaded to both ends of the bidirectional screw 3. A connecting rod 8 is hinged to the upper end of the threaded sleeve 7. The middle parts of the two connecting rods 8 are rotatably cross-connected through the same rotating shaft. A sliding sleeve 9 is connected to the upper end of the connecting rod 8. A fixed column 10 is fixedly connected to the lower end of the lifting platform 15. The sliding sleeve 9 is slidably connected to the fixed column 10. A telescopic column 4 is fixedly connected to the upper end of the base 1. The upper end of the telescopic column 4 is fixedly connected to the lifting platform 15. A rotary motor 21 is fixedly connected inside the lifting platform 15. A gear 20 is fixedly connected to the output end of the rotary motor 21. A gear ring 22 is fixedly connected to the lower end of the platform 12. The gear 20 and the gear ring 22 mesh with each other. The lower end of the lifting platform 15 is fixedly connected to the lifting ladder 5, and one end of the base 1 is fixedly connected to the storage sleeve 6. The shape of the storage sleeve 6 is adapted to the lifting ladder 5. The lower end of the lifting ladder 5 is fixedly connected to the contact pad 19, and the lower surface of the contact pad 19 is provided with anti-slip texture.

[0039] When the position of platform 12 needs to be adjusted, the drive motor 11 is first started to drive the bidirectional screw 3 to rotate, causing the threaded sleeve 7 to move in opposite directions, which in turn drives the connecting rod 8 to move, causing the upper end of the connecting rod 8 to drive the sliding sleeve 9 to move, thereby adjusting the angle of the connecting rod 8 to drive the telescopic column 4 to retract, thereby driving the lifting platform 15 and the adjusting platform 12 to rise and fall. Then, the rotary motor 21 is started to drive the gear 20 to rotate, which in turn drives the gear ring 22 to rotate, causing the platform 12 to rotate accordingly. This allows for convenient adjustment of the height and angle of the platform 12, making the welding process more convenient. When the lifting platform 15 is raised and lowered, the lower end of the lifting ladder 5 also moves along the storage sleeve 6. The lifting ladder 5 can adapt to the current height when the lifting platform 15 is raised and lowered, making the personnel more stable during the process of going up and down. As the lifting platform 15 falls, the contact pad 19 at the lower end of the lifting ladder 5 contacts the ground, which makes the device more stable when placed.

[0040] Working principle: When the position of platform 12 needs to be adjusted, the drive motor 11 is started first to drive the bidirectional screw 3 to rotate, so that the threaded sleeve 7 moves in opposite directions, thereby driving the connecting rod 8 to move, and the upper end of the connecting rod 8 drives the sliding sleeve 9 to move, thereby adjusting the angle of the connecting rod 8 and driving the telescopic column 4 to retract, thereby driving the lifting platform 15 and the adjusting platform 12 to rise and fall. Then, the rotary motor 21 is started to drive the gear 20 to rotate, and the gear 20 drives the gear ring 22 to rotate, so that the platform 12 rotates accordingly. The height and angle of the platform 12 can be easily adjusted, making the welding process more convenient. When the lifting platform 15 is raised and lowered, the lower end of the lifting ladder 5 also moves along the storage sleeve 6. The lifting ladder 5 can adapt to the current height when the lifting platform 15 is raised and lowered, making the personnel more stable during the process of going up and down. As the lifting platform 15 falls, the contact pad 19 at the lower end of the lifting ladder 5 contacts the ground, which makes the device more stable when placed.

[0041] When it is necessary to disassemble the CO2 welding machine installed in the mounting slot, first lower the lifting platform 15, which in turn lowers the platform 12. Then, start the mounting motor 27 to rotate the mounting screw 26, causing the moving plate 25 to move along the guide column 24 until the moving plate 25 moves to the disassembly port. At this time, the mounting plate 17 is no longer resisted by the lifting platform 15, and the mounting plate 17 rotates towards the ground along the moving plate 25. At this time, the buffer pad 16 contacts the ground, causing the mounting plate 17 to tilt at an angle. Then, start the electric push rod 23 to drive the push plate 18 away from the welding machine, so that the welding machine can be removed for replacement. This device can be easily disassembled, avoiding the inconvenience of manually moving the welding machine. During the process of assisting the welding machine in welding, this device can facilitate the disassembly, maintenance, and repair of the welding machine.
