Description

Technical Field

[0001] This invention belongs to the technical field of flame cutting workstations, and more specifically, relates to a mobile flame cutting workstation for complex terrain and its usage method. Background Technology

[0002] In the steel processing and equipment manufacturing industry, flame cutting of steel mainly employs two methods: manual cutting and small cutting machines. Manual cutting suffers from low efficiency, poor precision and quality, and the resulting smoke and dust pose significant health risks to operators. While small cutting machines can improve efficiency and quality, their low level of automation makes them unsuitable for mobile operations. Modern manufacturing has seen the emergence of robotic flame cutting equipment; however, these robots are typically confined to factories and their movement is limited by tracks, restricting their use to relatively small areas. Their application becomes problematic in highly mobile and complex terrain environments. Therefore, developing a workstation capable of moving across complex terrain while maintaining flame cutting performance is of great significance.

[0003] To address the aforementioned technical problems, Chinese Utility Model Patent CN211727834U discloses a horizontally movable flame cutting machine, comprising a device body. A movable platform is mounted on one side of the top surface of the device body, and a flame cutting machine is mounted on top of the movable platform. One end of the flame cutting machine is connected to a cutting head via a pipe. A cooling fan is mounted on top of the flame cutting machine, and one end of the cooling fan is connected to an air outlet hood via an exhaust pipe. In this utility model, a cooling fan is mounted on the top surface of the flame cutting machine, and one end of the cooling fan is connected to the air outlet hood via an exhaust pipe. By setting up the cooling fan, after the flame cutting machine has cut the part, the operator starts the cooling fan via a controller, and the cooling air generated by the cooling fan is blown onto the surface of the part through the air outlet hood, thereby cooling the surface of the part and preventing the part from deforming due to excessive temperature after cutting, thus improving the cutting quality of the part. Furthermore, Chinese Utility Model Patent CN213351143U discloses an intelligent and convenient mobile flame cutting machine. The device includes a walking mechanism, a fixed base plate, a cutting platform, and a robotic arm. The cutting platform is connected to the fixed base plate via a two-stage shock absorption system. A telescopic support rod is installed on the cutting platform. A control box and the robotic arm are located above the cutting platform. The robotic arm consists of a rotating base, a support column, a hinged seat, a swing wall, a rocker arm, and a support arm. The rotating base is located at the center of the cutting platform. A flame cutting head is mounted on the support arm, and a connector is located on the top of the flame cutting head, connecting to a flame cutting controller. The two symmetrical sides of the cutting platform are composed of several rectangular slots. This invention enables convenient transportation of the flame cutting machine, cutting of complex shapes at construction sites, stable cutting, a simple and reasonable structure, easy operation, high automation, and reduces cutting costs at construction sites.

[0004] The above-mentioned patented technologies still need to be improved in the following aspects: (1) The above technical solutions all realize the movement of the flame cutting workstation, but the above solutions will be difficult to achieve movement when facing stepped terrain with a large span; (2) When the workbench arrives at the designated construction site, it usually needs to move within a certain range to cover the work area of ​​that point. The existing technology has not proposed a technical solution for the workbench to have both long-distance movement and high stability movement at the construction site; (3) Although the existing technology provides a high stability movement technical solution with guide rails, the guide rails are usually set on the ground rather than part of the workbench body. Therefore, it has not proposed a solution for automatically retracting and extending the guide rails to meet the requirement that the slide rails are automatically released after the vehicle arrives at the site, thereby achieving high stability movement. Summary of the Invention

[0060] In this embodiment of the invention, by integrating a long-distance travel unit for long-distance travel in complex terrain and a short-distance stable sliding unit 4 for short-distance stable movement to cover the work area after arriving at the construction site, the flexible movement of the flame cutting workstation is effectively realized.

[0061] The working principle of this invention is as follows: First, oxygen and acetylene are filled into the gas management components at the factory, and strict sealing is performed between the gas management components used to store oxygen and acetylene to prevent leakage and mixing of the two gases, which could cause safety hazards. Next, the long-distance travel unit 2 is activated, which moves the entire equipment on the ground to reach the construction site. The long-distance travel unit 2 is then fully retracted, causing the short-distance stabilizing sliding unit 4 to contact the ground. Then, the flame cutting unit 3 is activated, and the flame cutting robotic arm 310 is adjusted to adjust its working angle through the cutting reversing drive motor 302, thereby realizing the flame cutting operation. At the same time, the short-distance stabilizing sliding unit 4 is activated, which stabilizes the flame cutting workstation at the working point and allows it to move stably within the working point range according to the work requirements, ensuring the flame cutting effect.

[0062] like Figure 1 As shown, assuming a forward direction on the left, when the flame cutting workstation encounters a stepped platform with a large span, the workstation maintains its forward movement. The extension angle control cylinder 202 of the first drive wheel set 211 is adjusted, and the tilt angle and extension length of the height adjustment cylinder 201 are controlled to ensure the driving wheels contact the upper surface of the step.

When the two symmetrically distributed close-range stabilizing sliding units 4 contact the ground and support the workstation base 1, the other two symmetrically distributed close-range stabilizing sliding units 4 must remain off the ground. Next, the linear sliding drive motor 413 is controlled to rotate, thereby sequentially engaging with the second transmission gear set 414, the sliding drive gear 415, and the toothed guide rail 432, thus driving the workstation base 1 to the right. Movement; then, when the workstation base 1 moves to the right and extends more than half its length, the other two symmetrically distributed close-range stabilizing sliding units 4 are controlled to contact the ground and support the workstation base 1. After being supported, the two symmetrically distributed close-range stabilizing sliding units 4 used in the first use are retracted to below the workstation base 1 by controlling the lowering drive motor 421, the linear sliding drive motor 413 and the lifting drive motor 4110.

[0078] S100: Oxygen and acetylene are filled into the gas management components at the factory, and strict sealing is performed between the two gas management components used to store oxygen and acetylene to prevent leakage and mixing of the two gases and the occurrence of safety hazards.

[0079] S200: Activate the long-distance travel unit 2, thereby driving the entire equipment to travel on the ground to reach the construction site, and control the long-distance travel unit 2 to retract completely, so that the short-distance stable sliding unit 4 contacts the ground;

[0080] S300: Start the flame cutting unit 3, and control the flame cutting robotic arm 310 to adjust the working angle through the cutting reversing drive motor 302, thereby realizing the flame cutting operation.

[0084] S203: When the workstation advances to the point where the fourth drive wheel set 214 is about to contact the step cross-section, the fourth drive wheel set 214 is retracted; then, when the workstation advances to the point where all drive wheel sets are completely on the upper surface of the step, the extension angle control cylinders 202 of each drive wheel set are extended, thereby completing the climbing process.

[0085] Step S300 further includes:
