Description

Technical Field

[0001] This utility model relates to the field of bridge welding technology, specifically a welding fixture for bridge steel formwork. Background Technology

[0002] In modern bridge construction projects, the application of bridge steel formwork is extremely widespread. As an important mold for pouring concrete bridge structures, the quality of bridge steel formwork is directly related to the safety and stability of the bridge. With the continuous expansion of the scale of bridge construction and the increasing requirements for engineering quality, the processing and manufacturing technology of bridge steel formwork has also received more and more attention. Welding is a key link in the production process of bridge steel formwork. Its welding quality not only affects the overall strength and sealing of the steel formwork, but also has an important impact on the service life of the bridge.

[0003] Currently, in the welding operations of bridge steel formwork, the commonly used welding fixtures are mainly designed for fixing and positioning the steel formwork to facilitate welding operations. During the welding process, the handling of welding slag and fumes usually relies on natural settling and manual cleaning. Some workshops are equipped with simple dust collection equipment, but these devices are not very effective in collecting and handling welding slag. If cleaning is not done in time, a large amount of welding slag will be scattered everywhere, not only polluting the working environment but also easily causing harm to surrounding equipment and personnel. Moreover, if the scattered welding slag accumulates in the work area and is not cleaned up in time, the high temperature it carries may cause fires and other safety accidents. Therefore, we propose a bridge steel formwork welding fixture to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a welding fixture for bridge steel formwork that can effectively collect welding slag and fumes generated during the welding process, while preventing the accumulation of welding slag from generating high temperatures and causing safety hazards. This can effectively solve the problems in the background art.

[0011] Furthermore, the left end of the slag-guiding pipe passes through the middle of the upper side wall of the mounting frame, and an induced draft fan is installed at the rear end of the water tank. The output port of the induced draft fan is connected to the lower right end of the slag-guiding pipe. A telescopic hose is provided at the input port of the induced draft fan, and the front end of the telescopic hose is located on the upper side of the welding table.

[0024] Slag collection mechanism 2 includes a slag collection bin 21, water passage holes 22, a flow guide frame 23, and a water pipe 25. An adjustable slag collection bin 21 is located on the left side of the interior of the water tank 1 (a material gate can be installed on the left side wall of the slag collection bin 21 for collecting welding slag inside the bin 21). The lower side wall of the slag collection bin 21 has evenly distributed water passage holes 22 (the water passage holes 22 are mainly used for drainage and circulation). A flow guide frame 23 is located at the upper interior of the slag collection bin 21 (the flow guide frame 23 is wider at the top and narrower at the bottom, and its side walls are all inclined and tapered, allowing welding slag to slide into the slag collection bin 21 through the inner wall of the flow guide frame 23). A water pipe 25 is located at the upper interior of the flow guide frame 23, and evenly distributed water passage holes are located at the lower end of the water pipe 25. The slag collection mechanism 2 also includes a baffle frame 24, and the inner wall of the flow guide frame 23... The end is equipped with a blocking frame 24. The slag collection mechanism 2 also includes a small water pump 26 and a telescopic pipe 27. The water inlet at the rear end of the water pipe 25 is equipped with an input water pipe. The rear end of the input water pipe passes through the guide frame 23 and the rear side wall of the slag collection bin 21 in sequence. The small water pump 26 is connected in series at the rear end of the input water pipe. The suction port of the small water pump 26 is equipped with a telescopic pipe 27. The lower end of the telescopic pipe 27 passes through the rear side wall of the water tank 1 and extends into the interior of the water tank 1. The input end of the small water pump 26 is electrically connected to the input end of the control switch group 16. The water pipe 25 is located inside the blocking frame 24. The rear end of the water tank 1 is equipped with a slag guiding pipe 5. The left end of the slag guiding pipe 5 is located on the upper side of the slag collection bin 21. The left end of the water tank 1 is equipped with a mounting frame 4. The front end between the upper and lower inner walls of the mounting frame 4 is equipped with a sliding column 13. The outer arc surface of the sliding column 13 slides... A slag collection bin 21 is dynamically connected. A screw rod 14 is rotatably connected between the upper and lower inner walls of the mounting frame 4. The rear end of the slag collection bin 21 is threadedly connected to the screw rod 14. A motor 15 is installed on the upper side rear end of the mounting frame 4. The output shaft of the motor 15 is fixedly connected to the center of the upper end face of the screw rod 14. The input end of the motor 15 is electrically connected to the input end of the control switch group 16. The left end of the slag-guiding pipe 5 passes through the middle of the upper side wall of the mounting frame 4. An induced draft fan 6 is installed at the rear end of the water tank 1. The output port of the induced draft fan 6 is connected to the lower right end of the slag-guiding pipe 5. A telescopic hose 7 is provided at the input port of the induced draft fan 6. The front end of the telescopic hose 7 is located on the upper side of the welding table 3. The input end of the induced draft fan 6 is electrically connected to the input end of the control switch group 16. The front and rear ends of the right side of the water tank 1 are connected. Each mounting plate 10 is equipped with a limiting slide post 12 between the opposite inner surfaces of the two mounting plates 10. A movable frame 8 is slidably connected to the outer arc surface of the limiting slide post 12. The front end of the telescopic hose 7 is located inside the movable frame 8. A lead screw 9 is rotatably connected between the opposite inner surfaces of the two mounting plates 10. The left end of the movable frame 8 is threadedly connected to the lead screw 9. A motor 11 is mounted on the rear side of the rear mounting plate 10. The output shaft of the motor 11 is fixedly connected to the center of the rear end face of the lead screw 9. The input end of the motor 11 is electrically connected to the input end of the control switch group 16. When the bridge steel formwork welding fixture is working, the welding operation is carried out on the welding table 3. The control switch group 16 starts the induced draft fan 6, which sucks in the welding slag and fumes generated during welding through the telescopic hose 7. During this process,The controllable switch group 16 starts the motor 11. The motor 11 drives the lead screw to rotate, causing the moving frame 8 to move back and forth on the limit slide column 12. This, in turn, moves the telescopic hose 7 to adjust its position, ensuring effective collection of welding slag and fumes generated at different locations. The slag is then transported through the slag inlet pipe 5 and falls into the slag collection bin 21. The welding slag slides into the slag collection bin 21 guided by the guide frame 23. At the same time, the small water pump 26 starts, drawing water from the water tank 1 through the telescopic pipe 27. The water is then transported through the inlet water pipe and sprayed out through the water holes of the water pipe 25 to cool and clean the welding slag in the slag collection bin 21, preventing the welding slag from adhering to the inner wall of the guide frame 23 and preventing welding slag from... The accumulation of slag generates high temperatures and pollution. The baffle 24 prevents welding slag from entering the water pipe 25 through the water hole and causing blockage. During welding, after the slag collection bin 21 collects a certain amount of welding slag, the motor 15 can be started, driving the lead screw 14 to rotate, causing the slag collection bin 21 to move up and down along the sliding column 13. When the slag collection bin 21 leaks into the water tank 1, it can be cleaned through the material door on the left side wall of the slag collection bin 21. During cleaning, the small water pump 26, induced draft fan 6, motor 15, and motor 11 can be turned off first, then the material door can be opened to clean the welding slag. After cleaning, the material door can be closed, and all equipment can be restarted to continue working. This method effectively handles the welding slag generated during the welding of bridge steel formwork.

[0025] The working principle of the bridge steel formwork welding fixture provided by this utility model is as follows: When the bridge steel formwork welding fixture is working, the welding operation is carried out on the welding table 3. The control switch group 16 starts the induced draft fan 6, which sucks in the welding slag and fumes generated during welding through the telescopic hose 7. During the process, the control switch group 16 can start the motor 11. The motor 11 drives the lead screw to rotate, causing the moving frame 8 to move back and forth on the limit slide column 12, thereby driving the telescopic hose 7 to adjust its position, ensuring that the welding slag and fumes generated at different positions can be effectively collected. The slag is then transported through the slag pipe 5 and falls into the slag collection bin 21. The welding slag slides into the slag collection bin 21 through the guide frame 23. At the same time, the small water pump 26 starts, drawing water from the water tank 1 through the telescopic pipe 27 and transporting it through the slag collection bin 21. The slag is transported through the water inlet pipe and sprayed out through the water holes of the water pipe 25 to cool and clean the welding slag in the slag collection bin 21, and to prevent the welding slag from sticking to the inner wall of the guide frame 23. At the same time, it prevents the welding slag from accumulating and generating high temperature and pollution. The blocking frame 24 can prevent the welding slag from entering the water pipe 25 through the water holes and causing blockage of the water pipe 25. During the welding process, after the slag collection bin 21 collects a certain amount of welding slag, the motor 15 can be started, which drives the lead screw 14 to rotate, so that the slag collection bin 21 moves up and down along the sliding column 13. When the slag collection bin 21 leaks out of the water tank 1, it can be cleaned through the material door on the left side wall of the slag collection bin 21. When cleaning, the small water pump 26, the induced draft fan 6, the motor 15 and the motor 11 can be turned off first, and then the material door can be opened to clean the welding slag. After cleaning, the material door can be closed and the equipment can be restarted to continue working.

[0026] It is worth noting that the small water pump 26 disclosed in the above embodiments can be of model PH-123E / 1, the induced draft fan 6 can be of model CX-75SA, and the motor 11 and the electric motor 15 can both be servo motors of model 86HB250-156B. The control switch group 16 is provided with control buttons that correspond one-to-one with the small water pump 26, the induced draft fan 6, the motor 11 and the electric motor 15 and are used to control their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
