Description

Technical Field

[0001] This utility model relates to the field of flange welding technology, specifically to a flange welding cleaning device. Background Technology

[0002] A flange has a disc-shaped edge with bolt holes and can be used on pipes, containers, or other equipment to provide a detachable connection for the system. If a flange connection is installed at a critical part of the pipeline, it can be easily opened to inspect the internal condition or to perform mechanical cleaning. For equipment that needs to be moved frequently, vibrated, or has significant thermal expansion and contraction, flange connections are more flexible and adaptable than rigid welding.

[0003] Flanges need to be securely connected to pipe interfaces for use, so welding is used to connect the flanges. However, there is slag at the welding position, which needs to be cleaned before the weld can be observed. Currently, cleaning the slag requires moving along the weld, which is inconvenient, and the cleaned slag can still easily cover the weld surface, making it difficult to observe. Therefore, this utility model proposes a flange welding cleaning device that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a flange welding cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange welding cleaning device, comprising a base, a sleeve rotatably connected to the base, the sleeve extending vertically and having a ring plate connected to its outer circumference at the top, the ring plate being used to support the flange, an abutment portion being provided inside the sleeve for abutting the inner wall of the pipe to which the flange is welded, multiple sets of telescopic rods circumferentially distributed at the upper end of the base, each set of telescopic rods having a pressure plate rotatably connected to its upper end, and each set of pressure plates having a locking bolt that can be screwed to the ring plate, the multiple sets of pressure plates being used to press the flange and cover the flange's connection hole;

[0006] The base is fixedly connected to a frame, on which an air shovel and a vacuum cleaner are mounted. A movable frame is slidably connected to the frame. The inlet end of the vacuum cleaner is connected to a suction pipe, which is connected to the movable frame by a clamp. The suction pipe has a suction head.

[0007] As a preferred technical solution, multiple seats are distributed on the lower side of the ring plate, and each set of seats is fitted with a ball bearing that rolls in contact with the upper surface of the base.

[0008] As a preferred technical solution, multiple through slots are formed on the base, and the multiple through slots are located below the ring plate. A brush ring is provided on the lower side of the ring plate, and multiple sets of brush strips are respectively on the outer side of the brush ring.

[0009] As a preferred technical solution, a drive motor is installed at the lower end of the base, the output shaft of the drive motor is connected to a gear, and a gear ring is provided on the outer wall of the sleeve, the gear meshing with the gear ring.

[0010] As a preferred technical solution, the straw is a universal shaped tube.

[0011] As a preferred technical solution, the abutting part includes a liner located inside the sleeve. Two sets of abutting rods are hinged to the top of the liner. A lifting cylinder is installed on the liner. The movable rod of the lifting cylinder is connected to a push plate. Two sets of pull rods are hinged to the push plate. The two sets of pull rods are hinged to the two sets of abutting rods in a one-to-one correspondence.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The ring plate drives the flange to rotate, which can thoroughly remove slag from the flange weld. After the weld slag is removed and separated by the air chisel, it will be sucked into the vacuum cleaner by the suction head as the flange rotates. The staff does not need to move around the flange to clean, which is highly efficient. The cleaned weld slag is adsorbed away from the weld surface, making it easy to observe whether there are defects such as pores and cracks in the weld. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5

[0022] Example 1 provides a flange welding cleaning device:

[0023] Please see Figure 3 , Figure 5 The base 10 is rotatably connected to a sleeve 22. The sleeve 22 extends vertically and is connected to a ring plate 20 on the outer ring of its top end. The ring plate 20 is used to support the flange. The sleeve 22 is provided with an abutment part 40, which is used to abut against the inner wall of the pipe to which the flange is welded. The flange after being welded to the pipe is placed on the ring plate 20. The upper end face of the ring plate 20 is smooth and burr-free. The abutment part 40 is located on the inner wall of the pipe and plays a positioning role for the flange.

[0024] Please see Figure 1 , Figure 3 A drive motor 12 is installed at the lower end of the base 10. The output shaft of the drive motor 12 is connected to a gear 121. A gear ring 221 is provided on the outer wall of the sleeve 22. The gear 121 meshes with the gear ring 221. A frame 30 is fixedly connected to the base 10. An air shovel 31 and a vacuum cleaner 32 are installed on the frame 30. A movable frame 33 is slidably connected to the frame 30. A suction pipe 321 is connected to the inlet end of the vacuum cleaner 32. The suction pipe 321 is connected to the movable frame 33 by a clamp. The suction pipe 321 has a suction head.

[0025] During cleaning, the movable frame 33 drives the suction tube 321 to move, bringing the suction head close to the welding position on one side of the flange. The suction tube 321 is a universal tube that can be flexibly bent for fine-tuning and adsorption. The worker holds the air shovel 31 to remove the welding slag at the welding position on the other side of the flange. The drive motor 12 rotates the sleeve 22 through the gear 121 meshing with the gear ring 221, thereby causing the ring plate 20 to drive the flange to rotate. This can thoroughly remove slag from the flange welding area. After the welding slag is removed and separated by the air shovel 31, it will be sucked into the vacuum cleaner 32 by the suction head as the flange rotates. The worker does not need to move around the flange for cleaning, which is highly efficient. The cleaned welding slag is adsorbed away from the welding surface, making it easy to observe whether there are defects such as pores and cracks at the welding area.

[0026] Please see Figure 3 , Figure 5Multiple sets of telescopic rods 23 are circumferentially distributed on the upper end of the base 10. Each set of telescopic rods 23 is rotatably connected to a pressure plate 231, and each pressure plate 231 is fitted with a locking bolt 232 that can be screwed onto the ring plate 20. The multiple sets of pressure plates 231 are used to press the flange and cover the flange's connection hole. The ring plate 20 is provided with multiple sets of screw holes, each set of screw holes corresponding to a set of locking bolts 232. After the flange is positioned, by rotating the pressure plate 231 to the upper side of the flange and rotating the locking bolt 232 to screw onto the screw hole, the telescopic rods 23 retract, and the pressure plates 231 press the upper side of the flange and cover the flange's connection hole. On the one hand, it further improves the clamping effect on the welded flange, making it stable when cleaning the welding slag. On the other hand, by covering the connection holes of the flange, the cleaned welding slag will not enter the connection holes, so there is no need to clean the connection holes again. Among them, the size of the pressure plate 231 is adapted to the size of the flange. The pressure plate 231 can be removed and replaced by bolts. The number of pressure plates 231 can be the same as the number of connection holes of the flange, so that the connection holes of the flange can be covered one by one. Alternatively, the number of pressure plates 231 can be half the number of connection holes of the flange, so that one set of pressure plates 231 can cover two sets of connection holes.

[0027] Example 2, based on Example 1 above, provides a flange welding cleaning device:

[0028] Please see Figure 3 Multiple seats are distributed on the lower side of the ring plate 20. Each set of seats is fitted with a ball bearing 24 that rolls in contact with the upper end face of the base 10. The ball bearing 24 rolls in contact with the upper end face of the base 10, improving the smoothness of the rotation of the ring plate 20.

[0029] Please see Figure 2 , Figure 3 Multiple through slots 11 are provided on the base 10, and the multiple through slots 11 are located below the ring plate 20. A brush ring 21 is provided on the lower side of the ring plate 20. Multiple sets of brush strips 211 are respectively on the outer side of the brush ring 21. The brush ring 21 is located on the outer side of multiple sets of ball bodies 24, which can block external dust or debris splashed by slag removal, reduce the impact on the movement of the ball bodies 24, and when the ring plate 20 rotates, the dust or debris outside the brush ring 21 can be brushed off from the through slots 11 by the movement of the brush strips 211. Each set of through slots 11 is connected to a slag discharge pipe 111.

[0030] Please see Figure 4 The abutting part 40 includes a liner 41 located inside the sleeve 22. Two sets of abutting rods 42 are hinged to the top of the liner 41. A lifting cylinder is installed on the liner 41. The lifting cylinder can be powered by a built-in battery. The movable rod of the lifting cylinder is connected to a push plate 43. Two sets of pull rods 44 are hinged to the push plate 43. The two sets of pull rods 44 are hinged to the two sets of abutting rods 42 in a one-to-one correspondence.

[0031] Please see Figure 4The abutment rod 42 has an abutment block 421. Through the movement of the movable rod of the lifting rod, the two sets of pull rods 44 pull the two sets of abutment rods 42 to pivot, thereby driving the abutment block 421 to abut against the top wall of the tube.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
