Most of the conventional welding platforms are designed with fixed heights and cannot adapt to welding operations at different heights. In actual operation, workers often need to use other tools or manually adjust the positions of the welding platforms, which not only increases the operation difficulty but also may lead to low welding efficiency and unstable welding quality. In addition, long-time height adjustment work increases the labor intensity of workers and has an adverse effect on their health. CONTENT OF THE UTILITY MODEL

[0027] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0028] It should be noted that like reference numerals and characters refer to like items throughout the drawings and like materials function in like manner, therefore, once an item is defined or described in one drawing, it is not necessary to discuss or describe it further in the description of the subsequent drawings.

[0029] To solve the technical problems in the background art, as shown in the description Figures 1-5 The application provides a technical solution: a stainless steel plate welding lifting platform, characterized by:

[0030] The base 1 is made of stainless steel flat plate material to ensure a solid flat plate structure. The base 1 is fixed to the ground by welding or bolting to ensure its stability and load-bearing capacity. The fixed pipe 2 is a vertical pipe that can be made of stainless steel or other materials and is fixed at the center of the base 1 by welding or bolting. Two grooves 3 are provided on the fixed pipe 2 for mounting the fixed block 4 and the fixed sheet 5. The lifting rod 6 is a telescopic stainless steel rod with a telescopic structure matching the inner diameter of the fixed pipe 2 at one end. The other end of the lifting rod 6 is connected to the workbench 8 by welding or bolting. The gear rack 7 is machined on the periphery of the lifting rod 6 corresponding to the grooves 3, and is arranged axially along the lifting rod 6 with alternating flat surfaces 9 and inclined surfaces 10. The first pawl 11 is hingedly fixed to the fixed block 4 and engaged with the gear rack 7. The first pawl 11 is designed with a horizontal surface 12 and an arc surface 13, which can slide on the gear rack 7 when the lifting rod 6 moves upward; when the lifting rod 6 is to move downward, the horizontal surface 12 abuts against the flat surface 9 to limit the downward movement of the lifting rod 6. One end of the second pawl 14 is hingedly fixed to one end of the hinged plate 15, and the other end of the second pawl 14 is engaged with the gear rack 7. The middle part of the hinged plate 15 is hingedly fixed to the fixed sheet 5, and the other end is hingedly connected to one end of the connecting rod 16. The other end of the connecting rod 16 is hingedly connected to the middle part of the connecting rod 17. One end of the connecting rod 17 is hingedly fixed to the fixed pipe 2, and the other end is designed with a pedal 18. A spring 19 is installed at the bottom of the pedal 18, and the other end of the spring 19 is fixed to the base 1. The spring 19 functions to reset the pedal 18 after it is released.

[0031] When the workbench 8 needs to be lifted, the pedal 18 is stepped on, the spring 19 is compressed, the second pawl 14 moves upward, and at the same time drives the gear rack 7 to slide upward, driving the lifting rod 6 to rise. When the lifting rod 6 rises to a certain position, the horizontal surface 12 of the first pawl 11 abuts against the flat surface 9 of the gear rack 7 to limit the downward movement of the lifting rod 6, achieving the fixation of the lifting platform, and the spring 19 resets the pedal 18, which can be repeatedly stepped on.

[0032] Further, two fixed blocks 4 are symmetrically welded or fixed beside the two grooves 3 on the fixed tube 2. Such design can provide better balance and stability. Since there are two fixed blocks 4, the first pawl 11 can be hinged together to achieve force balance.

[0033] It should be noted that the rack 7 is designed to be wider than the groove 3, so that when the rack 7 moves in the groove 3, it can maintain stable transmission performance, improve transmission efficiency, and make the contact between the first pawl 11 and the second pawl 14 and the rack 7 more stable, reduce wear and tear, and improve the durability and reliability of the lifting platform.

[0034] Further, if the first pawl 11 is divided by a hinge shaft, the first pawl 11 is composed of two main parts: the engagement end 20 and the limiting end 21. The engagement end 20 is designed to be in contact with the inclined surface 10 and the flat surface 9 of the rack 7, while the limiting end 21 is responsible for moving downward under the action of gravity to achieve automatic engagement. The center of gravity of the first pawl 11 is designed to be biased towards the limiting end 21, so that the limiting end 21 will naturally droop under the action of gravity when there is no external force, causing the engagement end 20 to contact and engage with the rack 7.

[0035] It should be noted that the limiting column 22 is a component fixed on the fixed block 4 perpendicular to the axial direction of the lifting rod 6. It can be a cylindrical or square column, and its material is the same as that of the fixed block 4 to ensure strength and durability. The limiting column 22 is designed to abut the upper part of the limiting end 21 of the first pawl 11. This design can limit the rotation angle of the first pawl 11 and prevent it from rotating excessively, thereby protecting the mechanical structure of the lifting platform from damage. During the fixing of the lifting rod 6, the engagement end 20 bears the downward force from the lifting rod 6, so that the limiting column 22 moves upward around the hinge shaft. The limiting column 22 can prevent the limiting end 21 of the first pawl 11 from rising excessively, avoiding the disengagement of the engagement end 20 from the rack 7, and ensuring the stability of the lifting rod 6 during the limiting process.

[0036] It should be noted that the positioning groove 23 is a slot provided on the limiting end 21 of the first pawl 11, which is matched in shape and size with the limiting column 22 to ensure that the limiting column 22 can be accurately inserted and fixed in the positioning groove 23. The design of the positioning groove 23 allows the limiting column 22 to smoothly slide into and be fixed therein, and such cooperation can reduce the shaking of the first pawl 11 during movement, improve its stability and accuracy. The positioning groove 23 not only provides a position to fix the limiting column 22, but also limits the rotation angle of the first pawl 11 to ensure the correct engagement of the engagement end 20 with the rack 7.

[0037] It should be noted that the pull rod 24 is a rod-shaped component connected to the limiting end 21 of the first pawl 11, which allows the operator to manually adjust the position and engagement state of the first pawl 11. The pull rod 24 can be fixed on the limiting end 21 of the first pawl 11 by welding, bolting or other mechanical connection methods to ensure stability and reliability during manual adjustment. The main function of the pull rod 24 is to provide a manual intervention mechanism, so that the operator can adjust the position of the first pawl 11 according to actual needs to ensure correct engagement with the rack 7.

[0038] It should be noted that the weight rod 25 is arranged on the second pawl 14, and the center of gravity and the engagement point of the second pawl 14 are located on both sides of the hinge shaft, respectively. Due to the distribution of the center of gravity and the engagement point of the second pawl 14 on both sides of the hinge shaft, the engagement force between the second pawl 14 and the rack 7 can be increased, and the carrying capacity and reliability of the lifting platform can be improved.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
