Description

Technical Field

[0001] This invention relates to the field of gas box welding technology, and specifically to a tooling for facilitating the positioning of gas boxes for switchgear welding. Background Technology

[0002] The switch cabinet contains a gas box, which houses circuit breakers, load switches, and other equipment. The outside of the gas box contains operating mechanisms and other equipment. The gas box is filled with gases such as SF6, N2, and dry air. Therefore, to ensure the gas box's airtightness, it is usually made of six welded panels.

[0003] Currently, most gas box welding is done manually. Since the gas box needs to be turned over manually, the welding efficiency is relatively low. In addition, the operators need not only good welding skills but also sufficient physical strength.

[0004] To improve welding efficiency, existing methods for welding gas boxes involve welding studs onto each gas box panel. These studs are used to secure corresponding clamps, enabling the gas box to be flipped and the panels welded. While this method effectively solves the problem of difficulty in flipping the gas box during manual welding and significantly reduces the workload of operators, the addition of studs necessitates grinding them after welding, greatly impacting production time and resulting in relatively low welding efficiency. Summary of the Invention

[0005] One of the objectives of this invention is to provide a tooling for easy welding and positioning of switchgear gas boxes, which can solve the problem of wasted labor caused by grinding the studs used in the prior art for fixing and flipping gas boxes, thereby improving welding efficiency and reducing the workload of operators.

[0006] To achieve the above objectives, a tooling for facilitating the welding and positioning of the switchgear gas box is provided, including reinforcing ribs fixed on each panel of the switchgear gas box; a fixing clamp is detachably connected to the reinforcing ribs.

[0007] The fixing clamp includes an active mechanism and a passive mechanism; one end of the active mechanism is detachably connected to the reinforcing rib, and the other end of the active mechanism is provided with an active connecting part; one end of the passive mechanism is detachably connected to the reinforcing rib, and the other end of the passive mechanism is provided with a passive connecting part.

[0008] The principle and effects of this solution: In this solution, reinforcing ribs are fixed on each panel of the switchgear gas box. These ribs connect the fixing clamps to the panels of the switchgear gas box. Compared to existing technologies that typically use studs on each panel of the switchgear gas box to fix the panels to the clamps, this solution eliminates the need to grind off the studs after welding the panels, as in existing technologies. Instead, after welding, only the fixing clamps need to be separated, while the reinforcing ribs are retained. The reinforcing ribs change the center of gravity of the panels, increasing their strength and greatly improving the robustness of the gas box formed after welding. This allows the gas box to better adapt to the environment after welding. Furthermore, since grinding is not required, production efficiency is greatly improved. This solution solves the problem of wasted labor due to grinding the studs used in existing technologies that fix and rotate the gas box, thus improving welding efficiency and reducing the workload of operators.

[0009] Meanwhile, one end of the active mechanism of the fixing fixture is detachably connected to the reinforcing rib, and the other end is connected to the active connecting part. One end of the passive mechanism is detachably connected to the reinforcing rib, and the other end is connected to the passive connecting part. The active and passive connecting parts are subsequently connected to the corresponding structures, thereby enabling the active connecting part to drive the passive connecting part to rotate and fix, thus realizing the rotation of the air box panel, facilitating the welding between the various panels of the air box. The setting of the fixing fixture further improves the welding efficiency and reduces the workload of the operators.

[0010] Furthermore, the cross-section of the reinforcing rib is U-shaped.

[0011] Beneficial effects: In this design, the cross-section of the reinforcing rib is U-shaped, which ensures the strength of the reinforcing rib while minimizing its weight, thus reducing the overall weight of the air box.

[0012] Furthermore, each panel is provided with multiple reinforcing ribs.

[0013] Beneficial effects: In this solution, multiple reinforcing ribs are set, which can enhance the compressive strength of the entire panel. At the same time, setting multiple reinforcing ribs on each panel can make it easier to fix the clamps and improve the firmness of the clamps during fixation.

[0014] Furthermore, the reinforcing rib has multiple mounting holes for bolts to pass through, and a nut that mates with the bolt thread is provided on the side of the mounting hole near the panel.

[0015] The active mechanism includes an active connecting part, on which a first connecting rod is provided. A first horizontal rod is provided at the end of the first connecting rod away from the active connecting part, and a first vertical rod is provided at both ends of the first horizontal rod. A first through hole for a bolt to pass through is provided on each of the first vertical rods.

[0016] The passive mechanism includes a passive connecting part, on which a second connecting rod is provided. A second horizontal rod is provided at the end of the second connecting rod away from the passive connecting part. A second vertical rod is provided at both ends of the second horizontal rod. A second through hole for a bolt to pass through is provided on each of the second vertical rods.

[0017] Beneficial effects: In this solution, the first and second vertical rods corresponding to the passive and active mechanisms are fixed to the two panels of the air box by bolts. Then, the rotation and fixation of the panels are achieved through the cooperation between the active and passive connecting parts, thereby achieving the welding and fixing of the panels.

[0018] Furthermore, a first oblique fixing rod is provided between the first vertical rod and the first horizontal rod, and a second oblique fixing rod is provided between the second vertical rod and the second horizontal rod.

[0019] Beneficial effects: In this solution, the reinforcement between the first vertical bar and the first horizontal bar, as well as between the second vertical bar and the second horizontal bar, is achieved by setting the first diagonal bar and the second diagonal fixing bar, which greatly improves the connection stability between the first vertical bar and the first horizontal bar, as well as between the second vertical bar and the second horizontal bar.

[0020] Furthermore, it also includes a rotating mechanism, which includes a base, on which a first support block and a second support block are respectively provided on both sides; the first support block is slidably engaged with the base, and a first cylinder is provided between the first support block and the second support block; the piston rod of the first cylinder is fixedly connected to the first support block, and the other end of the first cylinder is fixedly connected to the second support block; a driving mechanism for driving the active connecting part to rotate is also provided on the first support block, and the driving mechanism is fixedly connected to the active connecting part; the passive connecting part is rotatably connected to the second support block;

[0021] It also includes a controller, which is electrically connected to the first cylinder and the drive mechanism respectively.

[0022] Beneficial effects: In this solution, the drive mechanism is used to drive the active connecting part to rotate, and the passive connecting part is rotatably connected to the second support block. This setting enables the drive mechanism to flip the gas box, thereby facilitating the welding of the gas box and improving welding efficiency. At the same time, the first support block slides with the base, and a first cylinder is set between the first support block and the second support block. Under the control of the controller, the distance between the active mechanism and the passive mechanism can be adjusted, thus adapting to the welding work of switch cabinet gas boxes of various sizes.

[0023] Furthermore, it also includes a communication module electrically connected to the controller, a camera, and a robotic arm. The camera is located at the front end of the robotic arm. The controller is used to control the movement of the robotic arm. When the robotic arm moves to the welding position, the camera is activated to collect welding image information at the welding position, and the welding image information is sent to the server through the communication module.

[0024] The server includes:

[0025] The receiving module is used to receive welding image information;

[0026] The welding analysis module is used to analyze the welding condition at the welding location based on the welding image information and determine whether the welding at the welding location is qualified.

[0027] The alarm module is used to send an alarm signal when the welding at the welding position is determined to be unqualified;

[0028] The processing module is used to retrieve the current welding strategy corresponding to the welding position from the database when the welding at the welding position is determined to be unqualified, and analyze the specific orientation information of the welding position in the gas box. Based on the specific orientation information and the current welding strategy, the module analyzes the reasons for the welding failure and generates corresponding welding reason information.

[0029] The optimization module is used to optimize the current welding strategy based on the welding cause information and the current welding strategy, and update the current welding strategy in the database.

[0030] Beneficial effects: This solution controls the quality of gas box welding by inspecting the welding positions to ensure the welding is up to standard. Furthermore, when welding defects are encountered, timely analysis of the welding cause information and optimization of the current welding strategy greatly improves the reliability of subsequent welding.

[0031] Furthermore, the optimization module includes:

[0032] The strategy formation module is used to adjust the current welding strategy based on the welding cause information and the current welding strategy, and generate several different initial welding strategies.

[0033] The calculation module is used to calculate the fitness of the current welding strategy and the strategy corresponding to each initial welding strategy according to the preset strategy fitness function.

[0034] The fitness function of the strategy is as follows:

[0035]

[0036]

[0037] In the formula: n is the total number of steps corresponding to the welding strategy, R i Q represents the importance of step i relative to the welding strategy. i Z represents the effectiveness of step i in the welding strategy relative to the information addressing the welding cause; μ is the corresponding weighting coefficient, F1 is the corresponding first fitness; i F2 represents the operational difficulty corresponding to step j in the welding strategy, and F2 represents the first fitness.

[0038] The filtering module is used to judge the sum of the first fitness and the second fitness of the current welding strategy and other initial welding strategies, and to remove the initial welding strategies whose sum of fitness is less than that of the current welding strategy.

[0039] The hybridization and mutation module is used to determine whether hybridization and mutation should be performed according to a preset judgment formula; the judgment formula is:

[0040]

[0041] In the formula, H is the calculated value, and F 1D F represents the first fitness corresponding to the current welding strategy. 2D F represents the second fitness corresponding to the current welding strategy. 1M F represents the first fitness corresponding to the initial welding strategy M. 2M The second fitness corresponding to the initial welding strategy M;

[0042] If H is greater than or equal to the preset threshold, the corresponding initial welding strategy is output; otherwise, the initial welding strategies after screening are hybridized and mutated to form a new offspring welding strategy.

[0043] The loop module is used to continue executing the calculation module for the newly formed offspring welding strategy until the preset number of iterations is met;

[0044] The output module outputs the corresponding offspring welding strategy after satisfying the preset number of iterations, and updates the current welding strategy in the database.

[0045] Beneficial Effects: In this scheme, by calculating the first and second fitness, a clear understanding of the first and second fitness between the current welding strategy and each initial welding strategy is obtained. Then, the initial welding strategy is screened by summing the fitness values, thus effectively selecting welding strategies. Furthermore, the output of the corresponding strategy is defined: when the calculated value is greater than or equal to a preset threshold, and after reaching a preset number of iterations, the corresponding welding strategy is output to update the current welding strategy in the database, thereby updating the welding process and improving the welding pass rate.

[0046] Furthermore, the preset threshold is dynamically adjusted, and the value of the preset threshold is correlated with the sum of fitness corresponding to the current welding strategy.

[0047] Beneficial effects: In this scheme, the dynamic adjustment of the preset threshold and its correlation with the sum of the fitness of the corresponding current welding strategy greatly improves the rationality of the preset threshold setting, avoids excessively fast convergence, and improves the comprehensiveness of optimization.
