Description

Technical Field

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

[0002] Construction steel formwork is a metal formwork assembled and welded by steel materials. It is widely used in construction. Steel formwork needs to weld multiple ribs during welding, and the welding methods are also different. Among them, fusion welding is a welding method that heats the weldment joint to a molten state through a heat source to form a molten pool on the surface of the parent material and the filler material (or only the parent material), and then achieves metallurgical bonding after cooling and solidification. During welding, it needs to be stably placed by a supporting structure, and then continuous welding processing is performed by an intelligent welding hand; The utility model with the existing publication number CN214685018U belongs to the technical field of steel structure, 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 the practicality of the tooling. In addition, the tooling positions the steel formwork mechanism, and the positioning operation is simple, which saves 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 the steel formwork is manufactured in large quantities, in order to improve production efficiency, a cylinder-driven multi-link pressing clamp is used to press and fix the edge of the steel formwork. The existing cylinder-driven multi-link pressing 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

[0013] A method for treating a supporting structure of an intelligently welded surface of a building steel formwork by melting treatment, comprising the following steps: 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, so that the swing plate flips to the horizontal, and the pressing wheel presses the side of the steel formwork.

[0014] 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 transition groove, so that the center of the pressing wheel 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. During welding, since the pressing wheels are always overlapped, the support box can be pushed horizontally by the mobile telescopic cylinder to carry out effective fume treatment; Step three: 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 delivered 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 through the docking oil hole in the air flow groove of the movable oil plug. When the two docking oil holes are misaligned and the second hose continues to deliver 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 the bearing in the bearing groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When in 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. While the pressing wheel and the steel formwork maintain a downward clamping effect, the original obstructed position is exposed to facilitate welding operations. At the same time, with the pneumatic control of the control box, the negative pressure suction component and the lubrication component can be cooperated to collect welding fumes and self-lubricate the pressing wheel during rotation, making the operation worry-free and convenient.

[0025] A method for treating a supporting structure of an intelligently welded surface of a building steel formwork by melting treatment, comprising the following steps: 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 the high-pressure gas enters the bottom of the lifting piston chamber 8, and the high-pressure gas pushes the cylinder rod 9 and the lifting piston 11 to rise.

[0026] Step 2: During the welding process, high-pressure gas is continuously fed into the lower part 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 replenishing 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 air flow groove of the movable oil plug 32 in a natural state, a certain amount of lubricating oil will be injected 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, so as to lubricate the self-rotating mounting shaft 15 and the bearing in the bearing groove 14.

10. A method for treating a supporting structure of a building steel formwork intelligent welding surface melting treatment as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: When constructing a building steel formwork on top of 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 a suitable 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 connecting block (10) and the two connected matching arms to push the matching arms connected to the side support block (12), so that the swing plate (13) is flipped to a horizontal position, and the pressing wheel (16) presses the side of the steel formwork.

11. Step 2: During the welding process, high-pressure gas is continuously supplied from 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 gas 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; Step 3: After the self-rotating mounting shaft (15) and the pressing wheel (16) have been used for a long period of rotation, high-pressure gas can be continuously supplied to 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) rises, 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 a certain amount of lubricating oil is injected into the air flow groove of the movable oil plug (32) through the docking oil hole (36) in a natural state. When the two docking oil holes (36) are misaligned and the second hose (29) continuously delivers high-pressure airflow, 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).
