[0002] Steel structure guardrail is a guardrail structure made of steel as the main material. During the production and manufacturing process of steel structure guardrail, in order to ensure the quality and performance of the guardrail and ensure that the connection between the components is accurate and reliable, the staff generally use steel structure guardrail welding tooling to assist in the welding work.

However, it does not have a cleaning function. When the surface of the steel material used to make the steel structure guardrail carries oil, grease or moisture, the guardrail welding tooling that does not have a cleaning function will not be able to remove it. At this time, when two steel materials with oil, grease or moisture are welded together, pores or hydrogen embrittlement will appear in the weld, which will affect the stability of the entire steel structure guardrail, which will reduce the use effect of the steel structure guardrail welding tooling that is easy to position, and will also reduce the use efficiency of the steel structure guardrail welding tooling that is easy to position.

A placement frame 110 is fixed on the top of the connecting rod 109, and a battery 111 is placed inside the placement frame 110. A cover plate 112 is installed on the surface of the placement frame 110, and the cover plate 112 is located at the opening of the placement frame 110. A stabilizing block 113 is fixed between the arm 107 and the placement frame 110, and a controller 114 is installed on the top end face of the placement frame 110.

[0035] In this embodiment, when it is necessary to make a steel structure guardrail, the two mobile frames 101 and the handrail 107 are first used to move the entire welding tool to the place where it is needed, and then the battery 111 is used to power the tool, turn on the controller 114, and then set the basic usage parameters. After that, the controller 114 is used to turn on the four electric push rods 105 at the same time. At this time, each electric push rod 105 that is started will drive the corresponding other splint 104 to move with the cooperation of one of the splints 104 connected to it and the corresponding set of auxiliary rods 106. When all the other splints 104 are When it moves to the point where it cannot move, the controller 114 is used to pause all the electric push rods 105. Then, according to the size of the steel structure guardrail outer frame (composed of two columns, a fixed base and two cross bars), the height of the connecting block 103 from the ground is adjusted (the movable frame 101 has a height-adjustable function). Then, the two columns on the guardrail outer frame are moved respectively between each corresponding set of splints 104. Then, the controller 114 is used to start the four electric push rods 105, and the four started electric push rods 105 respectively reset the corresponding other splint 104 to its original position. When all four splints 104 are reset to their original positions, At this time, the controller 114 will pause the four electric push rods 105, and the guardrail outer frame can be clamped and fixed. Then the long rod 121 will be moved. Then the moving long rod 121 will drive all the T-shaped rods 117 to move with the cooperation of all the L-shaped blocks 120, and each moving T-shaped rod 117 will drive the first clamping block 116 connected to it to move. At the same time, each moving T-shaped rod 117 will also be in the cooperation of the corresponding second clamping block 118, so that the corresponding spring 119 is compressed. When all the T-shaped rods 117 are moved to a state where they cannot move, at this time, at each first clamping block 116 and each second clamping block 118, the spring 119 is compressed. Vertical pipes are placed between the two clamping blocks 118 (at this time, the bottoms of all vertical pipes are in contact with the bottom of the inner wall of the steel structure guardrail outer frame), and then the force applied to the long rod 121 is released. Then, under the cooperation of the rebound force of all springs 119, all T-shaped rods 117 and all second clamping blocks 118, all first clamping blocks 116 begin to reset. When all first clamping blocks 116 are reset to their original positions, all vertical pipes in contact with the steel structure guardrail outer frame are fixed. At this time, the vertical pipes and the guardrail outer frame are quickly positioned. Then the staff can use welding equipment to weld the vertical pipes and the guardrail outer frame together.

[0036] Example 2: According to Figure 1-Figure 5 and Figures 8-10As shown, the positioning and clamping mechanism 1 includes two mobile racks 101, and rectangular plates 108 are fixed on opposite sides of the two mobile racks 101. A connecting rod 109 is installed between the two rectangular plates 108. A placement rack 110 is fixed on the top of the connecting rod 109. A battery 111 is placed inside the placement rack 110, and a controller 114 is installed on the top end surface of the placement rack 110. A cleaning mechanism 2 is provided on the positioning and clamping mechanism 1, and the cleaning mechanism 2 includes a placement plate 201. A steam generator 202 is placed on the top of the placement plate 201, and the outer surface of the steam generator 202 is provided with two A fixing frame 203 is provided, a water tank 204 and a high-pressure air pump 207 are installed on the top of the placement plate 201, a water inlet pipe 206 is installed at the water outlet end of the water tank 204, an air outlet pipe 205 is installed at the air outlet end of the steam generator 202 and the air outlet end of the high-pressure air pump 207, a filter 208 is installed on the air inlet end face of the high-pressure air pump 207, a placement box 209 is fixed on the top of the placement plate 201, a manual valve 210 is installed at the air outlet end of the two air outlet pipes 205, a three-way pipe 211 is installed between the air outlet ends of the two manual valves 210, and a soft The air outlet end of the hose 212 is provided with a nozzle 213, a cylindrical block 214 is fixed to the bottom of the inner wall of the placement box 209, a mounting plate 215 is fixed to the top of the cylindrical block 214, and the two round holes on the mounting plate 215 are both connected to round rods 216 through bearings. The outer surfaces of the two round rods 216 are fixed with sprockets 217, and the bottoms of the two round rods 216 are fixed with levers 218. A motor 219 is installed on the top of the mounting plate 215. The two fixing frames 203 are both installed on the top of the placement plate 201 by screws. The water inlet end of the steam generator 202 is connected to the water inlet end of the steam generator 202. The water outlet ends of the water inlet pipe 206 are installed together, and the air outlet ends of the two air outlet pipes 205 are movable through the outer wall of the placement box 209. The two sprockets 217 are connected by a chain transmission. The handle ends of the two manual valves 210 are respectively located in the front end grooves of the two levers 218. The output end of the motor 219 is installed with the top end of one of the round rods 216. A box cover 220 is provided at the top opening of the placement box 209. The two manual valves 210, the hose 212 and the nozzle 213 are all inside the placement box 209. A plurality of stabilizing frames 221 are fixed to the bottom of the placement plate 201.

[0037] In this embodiment, when there is oil, grease or moisture on the surface of the steel structure guardrail frame (steel material) or the vertical pipe (steel material), the staff can use the battery 111 to power the steam generator 202, set various parameters, and then remove the box cover 220 from the placement box 209, and then remove the nozzle 213 from the inside of the placement box 209. At the same time, remove the hose 212 from the inside of the placement box 209, and then let the staff hold the nozzle 213 and align the outlet of the nozzle 213 with the place on the surface of the steel material that needs to be treated, and then start the steam generator 202. At this time, the started steam generator 202 will, with the cooperation of the water inlet pipe 206, pump out the water inside the water tank 204 and transport it to the steam generator 20 2. When water reaches the steam generating area inside the steam generator 202, the heating component inside the steam generator 202 heats the water into steam and transports it from its outlet end to the inside of the outlet pipe 205 connected thereto, and then transports it to the inside of the corresponding manual valve 210 (which is initially open), and then transports it to the inside of the three-way pipe 211, and then transports it to the inside of the hose 212, and then transports it to the inside of the nozzle 213, and then transports it to the surface of the steel material to be treated. When the high-temperature steam contacts the oil, grease or moisture on the surface of the steel material, the high-temperature steam will soften and emulsify the oil and grease, reduce its adhesion to the surface of the steel material, and allow the treated oil and grease to be discharged along with the high-temperature steam. The steam flow is taken away, and the high-temperature steam will also evaporate the water and let it be taken away with the high-temperature steam flow. When there is no oil or grease on the surface of the steel material, the steam generator 202 is turned off (at this time, there will still be residual water on the surface of the steel material), and then the motor 219 is started again. The started motor 219 will drive the two levers 218 to rotate at the same time with the cooperation of the bearings, two round rods 216, two sprockets 217, chains, cylindrical blocks 214 and mounting plates 215. When the two levers 218 complete the 90-degree rotation operation, the controller 114 will pause the motor 219 and then start the high-pressure air pump 207. The high-pressure air pump 207 that is then started will filter the air in the environment with the cooperation of the filter 208 before inhaling it. It is then transported to the inside of the air outlet pipe 205 connected to it, and then transported to the inside of the corresponding manual valve 210 (which is closed in the initial state and is now open), and then transported to the inside of the three-way pipe 211, and finally sprayed onto the surface of the previously treated steel material through the cooperation of the hose 212 and the nozzle 213. That is, the high-pressure gas sprayed by the nozzle 213 can quickly remove the residual moisture on the surface of the steel material, thereby ensuring that when the two steel materials are welded together, there will be no pores or hydrogen embrittlement at the weld, thereby ensuring the stability of the structure of the manufactured steel structure guardrail, which not only improves the use effect of the steel structure guardrail welding tooling that is easy to position, but also improves the use efficiency of the steel structure guardrail welding tooling that is easy to position.

[0038] The effect and working principle of the entire mechanism are as follows: when it is necessary to make a steel structure guardrail, the two mobile frames 101 and the handrail 107 are first used to move the entire welding tool to the place where it is needed, and then the battery 111 is used to power the controller 114, and then the basic usage parameters are set. Then, the controller 114 is used to turn on the four electric push rods 105 at the same time. At this time, each electric push rod 105 that is started will drive the corresponding other splint 104 to move with the cooperation of one of the splints 104 connected to it and the corresponding set of auxiliary rods 106. When all the other splints 104 are moved to a point where they cannot move, the controller 114 is used to pause all the electric push rods 105, and then according to the steel structure The size of the guardrail outer frame (composed of two uprights, a fixed base and two cross bars) is adjusted, the height of the connecting block 103 from the ground is adjusted (the movable frame 101 has a height-adjustable function), and then the two uprights on the guardrail outer frame are moved respectively between the corresponding sets of splints 104, and then the controller 114 is used to start the four electric push rods 105, so that the four started electric push rods 105 respectively reset the corresponding other splint 104 to its original position. When the four splints 104 are reset to their original positions, the controller 114 will pause the four electric push rods 105, and the guardrail outer frame can be clamped and fixed. Then the long rod 121 is moved, and then the moving long rod 121 will drive all the T-shaped rods 117 to move with the cooperation of all the L-shaped blocks 120. Each moving T-shaped rod 117 will drive the first clamping block 116 connected thereto to move, and at the same time, each moving T-shaped rod 117 will also compress the corresponding spring 119 under the cooperation of the corresponding second clamping block 118. When all the T-shaped rods 117 are moved to a point where they cannot move, a vertical pipe is placed between each first clamping block 116 and each second clamping block 118 (at this time, the bottoms of all vertical pipes are in contact with the bottom of the inner wall of the outer frame of the steel structure guardrail), and then the force applied to the long rod 121 is released. Then, under the rebound force of all springs 119, all T-shaped rods 117 and all second clamping blocks 118 cooperate, all first clamping blocks 116 begin to reset. When all first clamping blocks 116 are reset to their original positions, they are now in contact with the steel structure guardrail. All vertical pipes that are in contact with the guardrail outer frame are fixed, and the vertical pipes and the guardrail outer frame are quickly positioned. The staff can then use welding equipment to weld the vertical pipes and the guardrail outer frame together. When there is oil, grease or moisture on the surface of the steel structure guardrail outer frame (steel material) or the vertical pipe (steel material), the staff can use the battery 111 to power the steam generator 202, set various parameters, and then remove the box cover 220 from the placement box 209, and then remove the nozzle 213 from the inside of the placement box 209, and then remove the hose 212 from the inside of the placement box 209, and then let the staff hold the nozzle 213 and aim the outlet of the nozzle 213 at the place on the steel material surface that needs to be processed, and then start the steam generator 202.At this time, the started steam generator 202 will, with the cooperation of the water inlet pipe 206, pump out the water inside the water tank 204 and transport it to the steam generating area inside the steam generator 202. When the water reaches the steam generating area, the heating component inside the steam generator 202 will heat the water into steam and transport it out from its outlet end to the inside of the outlet pipe 205 connected thereto, and then transport it to the inside of the corresponding manual valve 210 (which is in the open state in the initial state), and then transport it to the inside of the three-way pipe 211, and then transport it to the inside of the hose 212, and then transport it to the inside of the nozzle 213, and then transport it to the surface of the steel material to be treated. When the high-temperature steam contacts the oil, grease or moisture on the surface of the steel material, the high-temperature steam will soften and emulsify the oil and grease, reduce its adhesion to the surface of the steel material, and allow the treated oil and grease to be taken away with the high-temperature steam airflow. At the same time, the high-temperature steam will also evaporate the moisture and allow it to be taken away with the high-temperature steam airflow. When there is no oil on the surface of the steel material When the steel material is dirty or grease-free, the steam generator 202 is turned off (moisture will still remain on the surface of the steel material), and then the motor 219 is started again. The started motor 219 will drive the two levers 218 to rotate simultaneously under the cooperation of the bearing, two round rods 216, two sprockets 217, chain, cylindrical block 214 and mounting plate 215. When the two levers 218 complete the 90-degree rotation operation, the controller 114 will pause the motor 219 and then start the high-pressure air pump 207. The high-pressure air pump 207 will filter the ambient air with the cooperation of the filter 208 and then inhale the air. The air is then transported to the inside of the outlet pipe 205 connected thereto, and then transported to the inside of the corresponding manual valve 210 (which is initially closed and is now open), and then transported to the inside of the tee pipe 211. Finally, it is sprayed onto the surface of the previously treated steel material through the cooperation of the hose 212 and the nozzle 213. That is, the high-pressure gas sprayed by the nozzle 213 can quickly remove the moisture remaining on the surface of the steel material. ,
