Description

Technical Field

[0001] This utility model relates to the field of petrochemical storage tanks, specifically to a welding device for a floating box body and a panel. Background Technology

[0002] A floating roof for an oil storage tank is a floating device that covers the surface of the liquid in the tank. It floats as the liquid level rises and falls, primarily used to reduce evaporation losses of the medium inside the tank and prevent oil and gas leaks. Through buoyancy, the floating roof isolates the liquid inside the tank from the atmosphere, thereby reducing oil evaporation losses.

[0003] The floating roofs currently in use are composed of several pontoon boxes pieced together, such as Figure 1 and Figure 2 A single floating box includes a box body A, an intermediate support body B, and a panel C. One end of the box body A is closed and the other end is open. The intermediate support body B is located inside the box body A and is fixed to the box body. After the panel C is fitted with the open end of the box body A, the panel C is fixed to the box body A by welding.

[0004] Currently, the method for welding cabinet A and panel C is to first spot weld cabinet A and panel C together, and then manually weld the gap between cabinet A and panel C. The disadvantages of this method are as follows:

[0005] First, manual welding is less efficient.

[0006] Secondly, although spot welding initially fixes the tank A and the panel C, the length of the tank A is relatively long (the standard tank length is generally 3.5 meters). Therefore, the width of the gap between the cover plate 3 and the tank A at different locations may be inconsistent. After manual welding at the gaps, the width of some parts of the float box exceeds the tolerance requirements. When these individual float boxes are spliced ​​together to form the float plate, gaps are formed between the float boxes. Although the gaps are small, they do not meet the safety and other requirements of petrochemical storage tanks.

[0007] Third, since the box body A and the cover plate 3 are not properly restrained, and the thickness of the box body A and the panel C is generally within 1.2mm, the box body A and the panel C are easily deformed due to the heat of welding during welding. After welding, the width of some parts of the floating box exceeds the tolerance requirements. Utility Model Content

[0008] This invention provides a welding device for the pontoon box body and the panel. This invention not only has high welding efficiency, but also ensures the accuracy requirements of the pontoon box.

[0009] The technical solutions to the above technical problems are as follows:

[0010] The welding device for the pontoon box body and the panel includes:

[0011] Welding robots;

[0012] The base located on one side of the welding robot;

[0013] A first blocking component is used to block the first long side of the housing, and the first blocking component is fixed to the base;

[0014] A second blocking assembly is used to block the first wide side of the housing; the second blocking assembly is fixed to the base.

[0015] A first pressure-applying component that applies pressure to the second long side of the housing; the first pressure-applying component is mounted on the base and arranged opposite to the first blocking component.

[0016] A second pressure-applying component applies pressure to the second wide side of the housing; the second pressure-applying component is mounted on the base and arranged opposite to the second blocking component.

[0017] A controller that controls the linear motion of the first and second pressure components, the controller being connected to the first and second pressure components respectively.

[0018] In operation, the box with the panel is placed within the area enclosed by a blocking component, a second blocking component, a first pressure-applying component, and a second pressure-applying component. The box is supported by a first pad and a second pad. The first long side of the box engages with a first stop bar, and the second long side engages with a second stop bar. The first linear drive component is activated, driving a first pressure plate towards the box. The first pressure plate pushes the box towards the first stop bar. The second linear drive component is then activated, driving a second pressure plate towards the box. The second pressure plate pushes the box towards the second stop bar. Finally, the box is clamped between the first stop bar, the first pressure plate, the second stop bar, and the second pressure plate. Since the panel is located inside the box, the first and second pressure plates apply pressure to the box (the pressure areas correspond to the panel), ensuring a tight fit between the panel and the box. A welding robot then performs welding on the areas where the panel and box need to be welded.

[0019] The aforementioned box and panel are tightly joined before welding, and the entire box remains clamped during welding. Therefore, deformation caused by welding is avoided, ensuring the pontoon's precision requirements. Furthermore, the use of a welding robot improves welding efficiency. Attached Figure Description

Detailed Implementation

[0029] like Figures 3 to 8 As shown, the welding device for the floating box body and the panel of this utility model includes a welding robot 1, a base 2, a first blocking component, a second blocking component, a first pressure-applying component, a second pressure-applying component, and a controller K. The controller K controls the linear movement of the first pressure-applying component and the second pressure-applying component, and the controller K is connected to the first pressure-applying component and the second pressure-applying component respectively. The following is a detailed description of each part and the relationship between them.

[0030] The welding robot 1 can be fixed or movable. In this embodiment, a movable welding robot 1 is preferred. For example, the welding robot 1 includes a welding robot body 1a and a walking mechanism 1b. The welding robot body 1a is connected to the walking mechanism 1b. The walking mechanism 1b is arranged along the length of the base 2. The structures of the welding robot body 1a and the walking mechanism 1b are existing technologies and will not be described in detail here.

[0031] The base 2 is located on one side of the welding robot 1. The base 2 includes a fixed base 2a, a movable base 2b, a first guide rail 2c, and a first linear actuator 2d. The fixed base 2a is fixed to a base, such as a base installed on the foundation of a workshop. The first guide rail 2c is arranged along the length of the fixed base 2a and fixed to the fixed base 2a. The movable base 2b is slidably engaged with the first guide rail 2c. The first linear actuator 2d is fixedly connected to the fixed base 2a. The first linear actuator 2d can be a linear drive component such as a cylinder or a hydraulic cylinder. In this embodiment, a cylinder is preferred for the first linear actuator 2d. The power output end of the first linear actuator 2d is connected to the movable base 2b. When the first linear actuator 2d is working, it drives the movable base 2b to move linearly along the length direction of the fixed base 2a. The first linear actuator 2d is also connected to the controller K. The controller K may include a PLC controller and several solenoid valves. The solenoid valves are electrically connected to the PLC controller and connected to the compressed gas pipeline. The pipeline is connected to the cylinder. When the PLC controller controls the solenoid valve to open, compressed gas is input into the cylinder. When the PLC controller controls the solenoid valve to close, the compressed gas is cut off from the supply to the cylinder.

[0032] The base 2 also includes a first limiting seat 2e and a detection component 2f. The first limiting seat 2e restricts the position of the movable base 2b during displacement. The first limiting seat 2e is fixed at both ends of the fixed base 2a. The detection component 2f is used to detect the position of the movable base 2b. The first limiting seat 2e and the detection component 2f are installed at both ends of the base 2. The detection component 2f is connected to the controller K. The detection component 2f is a limit switch or a tactile switch. When the first linear actuator 2d drives the movable base 2b to move linearly along the length of the fixed base 2a, the movable base 2b touches the detection component 2f. At this time, the movable base 2b and the first limiting seat 2e form abutment. Simultaneously, the detection component 2f feeds back a detection signal to the PLC controller. The PLC controller controls the first linear actuator 2d to stop working, thus the movable base 2b is pressed against the first limiting seat 2e by the force applied by the cylinder.

[0033] Generally, the box A is rectangular, with two long sides and two wide sides. In this embodiment, the base 2 also includes a first pad 2g and a second pad 2h for supporting the box A. The first pad 2g and the second pad 2h are respectively fixed to the movable base 2b. A first blocking assembly is used to block the first long side of the box A. The first blocking assembly is fixed to the base 2. The first blocking assembly includes a first support 3 and a first stop bar 4. One end of the first support 3 is fixed to the base 2, and the other end of the first support 3 is fixed to the first stop bar 4. The first stop bar 4 is arranged along the length direction of the base 2. The first support 3 includes an L-shaped support and a rib. The L-shaped support is fixed to the movable base 2b, and the rib is fixed to the L-shaped support.

[0034] The second blocking assembly is used to block the first wide side of the housing. The first blocking assembly is fixed to the base 2. The second blocking assembly includes a second support 5 and a second baffle 6. One end of the second support 5 is fixed to the base 2, and the other end of the second support 5 is fixed to the second baffle 6. The second baffle 6 is arranged along the width direction of the base 2. The second support 5 includes an L-shaped support and a rib. The L-shaped support is fixed to the movable base 2b, and the rib is fixed to the L-shaped support.

[0035] The first pressure-applying component applies pressure to the second long side of the housing A. The first pressure-applying component is mounted on the base 2 and arranged opposite to the first blocking component. In this embodiment, there are multiple sets of the first pressure-applying components. Each set includes a first mounting base 7, a first linear drive component 8, and a first pressure plate 9. The first mounting base 7 is connected to the base 2 and includes an L-shaped mounting seat and ribs fixed to the mounting seat. The first linear drive component 8 is mounted on the first mounting base 7. The first linear drive component 8 can be a cylinder or a hydraulic cylinder. In this embodiment, a cylinder is preferred. The controller K is connected to the first linear drive component 8, and the power output end of the first linear drive component 8 is fixedly connected to the first pressure plate 9. When the first linear drive component 8 is working, it drives the first pressure plate 9 to move towards the housing A. The first pressure plate 9 applies pressure to the housing A, thereby clamping the housing A between the first blocking rib 4 and the first pressure plate 9. Before pressure is applied, since the panel C is placed inside the housing A, after pressure is applied, the panel C and the housing A form a tight fit.

[0036] In this embodiment, the first pressure-applying component further includes a first slide block 10, a first slide rail 11, and a first pin 12. The first mounting base 7 is fixed to the first slide block 10, and the first slide block 10 is slidably engaged with the first slide rail 11. The first slide rail 11 is preferentially fixed to the movable base 2b in the base 2. The base 2 is provided with a first insertion hole 2j for engaging with the first pin 12. There are multiple first insertion holes 2j. As needed, the first pin 12 is inserted into one of the first insertion holes 2j. Therefore, before applying pressure to the box A, this structure can be adjusted according to the width of the box A.

[0037] The first pressure-applying assembly also includes a first screw 13, a first adjusting nut 14, a second adjusting nut 15, a first guide rod 16, and a first guide sleeve 17. The first screw 13 is fixed to the first pressure plate 9. The first adjusting nut 14 is threadedly connected to the first screw 13. A first through hole is provided on the first mounting base 7. The first screw 13 passes through the first through hole on the first mounting base 7 and is threadedly connected to the second adjusting nut 15. The first screw 13 and the first through hole on the first mounting base 7 are clearance-fitted. The first mounting base 7 is located between the first adjusting nut 14 and the second adjusting nut 15. The first guide rod 16 is fixed to the first pressure plate 9. The first guide rod 16 passes through the first guide sleeve 17 and is slidably fitted with the first guide sleeve 17. The first guide sleeve 17 is fixed to the first mounting base 7.

[0038] When the first pin 12 is inserted into the first insertion hole 2j, the first slide block 10 cannot slide along the first slide rail 11, and the first mounting base 7 is fixed to the first slide block 10, so the first mounting base 7 cannot move either. When the piston rod of the first linear drive component 8 extends, the first pressure plate 9 feeds towards the housing A, and the first screw 13 moves with the first pressure plate 9. When the second adjusting nut 15 abuts against the first mounting base 7, the first pressure plate 9 cannot continue to feed towards the housing A, and the feed amount of the first pressure plate 9 reaches its maximum value. Therefore, by adjusting the position of the second nut 15 on the first screw 13, the feed amount of the first pressure plate 9 towards the housing A can be controlled, thereby avoiding excessive pressure on the housing A and causing damage to the housing A. When the piston rod of the first linear drive component 8 retracts, the first linear drive component 8 drives the first pressure plate 9 to gradually move away from the housing A. When the first adjusting nut 14 abuts against the first mounting base 7, the piston rod of the first linear drive component 8 can no longer retract. By adjusting the first adjusting nut 14, it is easy to make the first pressure plate 9 in each group of first pressure application components be on the same straight line.

[0039] The second pressure-applying component applies pressure to the second wide side of housing A. The second pressure-applying component is mounted on base 2 and arranged opposite to the second blocking component. In this embodiment, there are multiple sets of second pressure-applying components. Each set includes a second mounting base 18, a second linear drive component 19, and a second pressure plate 20. The second mounting base 18 is connected to base 2 and includes an L-shaped mounting seat and ribs. The mounting seat is fixed to the movable base 2b, and the ribs are fixed to the mounting seat. The second linear drive component 19 is fixed to the second mounting base 18. In this embodiment, the second linear drive component 19 is preferably a cylinder. The controller K is connected to the second linear drive component 19, and the power output end of the second linear drive component 19 is fixed to the second pressure plate 20.

[0040] The second pressure-applying assembly also includes a second screw 21, a third adjusting nut 22, a fourth adjusting nut 23, a second guide rod 24, and a second guide sleeve 25. The second screw 21 is fixed to the second pressure plate 20. The third adjusting nut 22 is threadedly connected to the second screw 21. A second through hole is provided on the second mounting base 18. The second screw 21 passes through the second through hole on the second mounting base 18 and is threadedly connected to the fourth adjusting nut 23. The second screw 21 and the second through hole on the second mounting base 18 are clearance-fitted. The second mounting base 18 is located between the third adjusting nut 22 and the fourth adjusting nut 23. The second guide rod 24 is fixed to the second pressure plate 20. The second guide rod 24 passes through the second mounting base 18 and is slidably fitted with the second guide sleeve 25. The second guide rod 24 is fixed to the second mounting base 18.

[0041] When the piston rod of the second linear drive component 19 extends, the second pressure plate 20 feeds towards the housing A, and the second screw 21 moves along with the second pressure plate 20. When the fourth adjusting nut 23 abuts against the second mounting base 18, the second pressure plate 20 can no longer feed towards the housing A, and the feed amount of the second pressure plate 20 reaches its maximum value. Therefore, by adjusting the position of the fourth adjusting nut 23 on the second screw 21, the feed amount of the second pressure plate 20 towards the housing A can be controlled, thereby avoiding excessive pressure on the housing A and damage to the housing A. When the piston rod of the second linear drive component 19 retracts, the second linear drive component 19 drives the second pressure plate 20 to gradually move away from the housing A. When the third adjusting nut 22 abuts against the second mounting base 18, the piston rod of the second linear drive component 19 can no longer retract. Therefore, by adjusting the third adjusting nut 22, it is easy to make the second pressure plates 20 in each group of second pressure application components be on the same straight line.

[0042] The usage process of this utility model is as follows:

[0043] The housing A, equipped with panel C, is placed within the area enclosed by a blocking component, a second blocking component, a first pressure-applying component, and a second pressure-applying component. Housing A is supported by a first pad 2g and a second pad 2h. The first long side of housing A engages with the first stop bar 4, and the second long side engages with the second stop bar 6. The first linear drive component 8 is activated, driving the first pressure plate 9 towards housing A. The first pressure plate 9 pushes housing A towards the first stop bar 4. The second linear drive component 19 is then activated, driving the second pressure plate 20 towards housing A. The second pressure plate 20 pushes housing A towards the second stop bar 6. Finally, housing A is clamped between the first stop bar 4, the first pressure plate 9, the second stop bar 6, and the second pressure plate 20. Since panel C is located inside housing A, the first pressure plate 9 and the second pressure plate 20 apply pressure to housing A (the pressure area corresponds to panel C), causing panel C to adhere to housing A. Welding robot 1 is working, welding panel C and box A to the parts that need to be welded.
