Description

Technical Field

[0001] The present invention relates to the technical field of intelligent welding, and in particular to a supporting structure and a treatment method for intelligent welding surface melting treatment of building steel formwork. Background Art

[0002] Construction steel formwork is a metal formwork assembled and welded from steel materials. It is widely used in construction. Steel formwork requires welding multiple ribs, and the welding methods vary. Fusion welding is a welding method that uses a heat source to heat the weldment joint to a molten state, forming a molten pool on the surface of the parent material and filler material (or only the parent material). After cooling and solidification, a metallurgical bond is achieved. During welding, it needs to be stabilized by a support structure, and then continuously welded by an intelligent welding hand.

[0003] The utility model with the existing publication number CN214685018U belongs to the field of steel structure technology, and is particularly a steel formwork welding tool, including a tooling table and a protective pad. By arranging a slide plate, an electric-controlled sliding connection block, a fixed baffle, a positioning plate and a threaded rod, when the tooling is used to fix the steel formwork, the distance between the tooling can be adjusted according to the size of the steel formwork, thereby improving the use range of the tooling and increasing the practicality of the tooling. In addition, the tooling positions the steel formwork mechanism, and the positioning operation is simple, saving time and effort, thereby increasing the work efficiency of the staff and improving the product production volume. When the above-mentioned steel formwork welding tooling is in use, the problems of positioning and improving efficiency can be solved through the cooperation between various mechanisms. When steel formwork is manufactured in large quantities, in order to improve production efficiency, a cylinder-driven multi-link downward pressure clamp is used to press and fix the edge of the steel formwork. The existing cylinder-driven multi-link downward pressure clamp has a relatively single function when supporting and fixing the steel formwork, and during the welding process, the side pressing method is not convenient for the welding equipment to weld the edge of the steel formwork. It is often necessary to disassemble the steel formwork and then weld the edge of the steel formwork separately, which is inconvenient to operate and use. Summary of the Invention

[0017] A method for treating a supporting structure of an intelligently welded surface of a building steel formwork by melting treatment comprises the following steps:

[0018] Step 1: When constructing the building steel formwork above the welding support platform, first assemble and splice the steel formwork, and then according to the pressing position, push the support box to the appropriate position by moving the telescopic cylinder, and then high-pressure gas enters the bottom of the lifting piston cavity. The high-pressure gas pushes the cylinder rod and the lifting piston to rise. At this time, the cylinder rod controls the end connecting block and the two connected matching arms, and pushes the matching arms connected to the side support blocks, and then the swing plate flips to the horizontal, and the pressing wheel presses the side of the steel formwork.

[0019] Step 2: During the welding process, high-pressure gas is continuously fed into the lower part of the lifting piston cavity. When the high-pressure gas exceeds the limit of the first one-way valve, the high-pressure gas enters the high-speed ventilation groove through the first gas feeding groove and the first hose. Then, the gas in the high-speed ventilation groove flows, driving the negative pressure at the position of the suction groove and the annular adapter groove, so that the center of the pressing wheel pointing to the welding position is used to suck the welding fume. The fume then enters the rear-stage fume treatment equipment along with the high-speed ventilation groove. During welding, since the pressing wheels are always overlapped, the support box can be pushed horizontally by moving the telescopic cylinder to effectively treat the fume.

[0020] Step 3: After the self-rotating mounting shaft and the pressing wheel have been used for a long period of rotation, high-pressure gas can be continuously supplied to the upper end of the lifting piston cavity. When the lifting piston remains in position and the air pressure above the lifting piston is greater than the supporting force of the supporting spring, the annular piston plate retracts into the annular air groove, and the high-pressure gas above the lifting piston cavity enters the oil supply pipe from the second air supply groove and the second hose. Then, under the action of the second one-way valve, the high-pressure gas first pushes the movable oil plug to rise, and the docking oil hole of the movable oil plug is misaligned with the docking oil hole of the oil supply pipe. Under the natural state, a certain amount of lubricating oil will be injected into the air flow groove of the movable oil plug through the docking oil hole. When the two docking oil holes are misaligned and the second hose continues to supply high-pressure airflow, the high-pressure airflow will blow the lubricating oil in the movable oil plug into the bearing groove through the annular oil guide groove and the oil blowing groove, thereby lubricating the self-rotating mounting shaft and bearings in the bearing groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] During use, the steel formwork above the welding support table can be quickly pressed and fixed through the cooperation of the control box and the swing plate. When the outer edge of the steel formwork needs to be welded, the support box can be pushed horizontally by moving the telescopic cylinder. When the pressing wheel and the steel formwork maintain a downward clamping effect, the originally blocked position is exposed to facilitate welding operations. At the same time, with the pneumatic control of the control box, it can cooperate with the negative pressure suction component and the lubrication component to collect welding smoke and the pressing wheel can rotate for self-lubrication, making operation worry-free and convenient.

[0042] A method for treating a supporting structure of an intelligently welded surface of a building steel formwork by melting treatment comprises the following steps:

[0043] Step 1: When constructing the building steel formwork above the welding support platform 1, the steel formwork is first assembled and spliced, and then the support box 3 is pushed to the appropriate position by moving the telescopic cylinder 38 according to the pressing position, and then high-pressure gas enters the bottom of the lifting piston chamber 8. The high-pressure gas pushes the cylinder rod 9 and the lifting piston 11 to rise. At this time, the cylinder rod 9 controls the end connecting block 10 and the two connected matching arms, and pushes the matching arms connected to the side support block 12, and then the swing plate 13 is flipped to the horizontal, and the pressing wheel 16 presses the side of the steel formwork.

[0044] Step 2: During the welding process, high-pressure gas is continuously fed into the lower part of the lifting piston chamber 8. When the high-pressure gas exceeds the limit of the first one-way valve 22, the high-pressure gas enters the high-speed ventilation groove 18 through the first air supply groove 21 and the first hose 23. Then the gas in the high-speed ventilation groove 18 flows, driving the negative pressure at the position of the suction groove 17 and the annular adapter groove 19, so that the center of the pressing wheel 16 pointing to the welding position is used to suck the welding fume, and then enters the rear-stage fume treatment equipment along with the high-speed ventilation groove 18. During welding, since the pressing wheel 16 is always overlapped, the support box 3 can be pushed to move horizontally by the movable telescopic cylinder 38 to carry out effective fume treatment, and the movable shift support box 3 can facilitate the intelligent welding hand to move to the original shielded position for welding operation;

[0045] Step 3: After the self-rotating mounting shaft 15 and the pressing wheel 16 have been rotating for a long time, high-pressure gas can be continuously fed into the upper end of the lifting piston chamber 8. When the lifting piston 11 remains in position and the air pressure above the lifting piston 11 is greater than the supporting force of the support spring 26, the annular piston plate 25 retracts into the annular air groove 24, and the high-pressure gas above the lifting piston chamber 8 enters the oil supply pipe 31 from the second air supply groove 27 and the second hose 29. Then, the high-pressure gas, under the action of the second one-way valve 37, first pushes the movable oil plug 32 rises, and the docking oil hole 36 of the movable oil plug 32 is misaligned with the docking oil hole 36 of the oil replenishing pipe 31. In the natural state, a certain amount of lubricating oil will be poured into the air flow groove of the movable oil plug 32 through the docking oil hole 36. When the two docking oil holes 36 are misaligned and the second hose 29 continuously delivers high-pressure airflow, the high-pressure airflow will impact the lubricating oil in the movable oil plug 32 and blow it into the bearing groove 14 through the annular oil guide groove 33 and the oil blowing groove 34, thereby lubricating the rotating mounting shaft 15 and the bearing in the bearing groove 14.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

A method for treating a supporting structure of an intelligent welding surface melting treatment of a building steel formwork according to any one of claims 1 to 4, characterized in that: The following steps are involved: Step 1: When constructing a building steel formwork above the welding support platform (1), the steel formwork is first assembled and spliced. Then, according to the pressing position, the support box (3) is pushed to the appropriate position by moving the telescopic cylinder (38). Then, high-pressure gas enters the lower part of the lifting piston chamber (8). The high-pressure gas pushes the cylinder rod (9) and the lifting piston (11) upward. At this time, the cylinder rod (9) controls the end connection block (10) and the two connected matching arms to push the matching arms connected to the side support block (12), and then the swing plate (13) is flipped to the horizontal, and the pressing wheel (16) presses the side of the steel formwork; Step 2: During the welding process, high-pressure gas is continuously fed into the lower part of the lifting piston chamber (8). When the high-pressure gas exceeds the limit of the first one-way valve (22), the high-pressure gas enters the high-speed ventilation groove (18) through the first air feeding groove (21) and the first hose (23). Then, the gas in the high-speed ventilation groove (18) flows, driving the negative pressure at the position of the suction groove (17) and the annular adapter groove (19), so that the center of the pressing wheel (16) pointing to the welding position is used to suck the welding fume, and then enters the rear-stage fume treatment equipment along with the high-speed ventilation groove (18). During the welding process, since the pressing wheel (16) is always overlapped, the support box (3) is pushed to move horizontally by the moving telescopic cylinder (38) to effectively treat the fume; Step 3: After the self-rotating mounting shaft (15) and the pressing wheel (16) have been used for a long time, high-pressure gas is continuously fed into the upper end of the lifting piston chamber (8). When the lifting piston (11) remains in position and the air pressure above the lifting piston (11) is greater than the supporting force of the supporting spring (26), the annular piston plate (25) retracts into the annular air groove (24), and the high-pressure gas above the lifting piston chamber (8) enters the oil supply pipe (31) from the second air supply groove (27) and the second hose (29). Then, the high-pressure gas, under the action of the second one-way valve (37), first pushes the movable oil plug (3 2) Ascend, the docking oil hole (36) of the movable oil plug (32) is misaligned with the docking oil hole (36) of the oil supply pipe (31), and the air flow groove of the movable oil plug (32) is naturally filled with a certain amount of lubricating oil through the docking oil hole (36). When the two docking oil holes (36) are misaligned, the second hose (29) continuously delivers high-pressure airflow, and the high-pressure airflow will blow the lubricating oil in the movable oil plug (32) into the bearing groove (14) through the annular oil guide groove (33) and the oil blowing groove (34), thereby lubricating the self-rotating mounting shaft (15) and the bearing in the bearing groove (14).
