Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an auxiliary device for cleaning the walls of metal storage tanks. Background Technology

[0002] During the installation of large metal storage tank walls, after the submerged arc welding of the upper and lower wall panels is completed, the back of the wall panels needs to be cleaned, and the weld scars, weld surfaces, and both sides of the weld need to be ground and cleaned to meet welding requirements. Typically, handheld 180 or 250 type angle grinders are used on-site for weld grinding and cleaning. However, each 180 or 250 type angle grinder weighs approximately 15-20 catties (quite heavy). Workers using handheld angle grinders become tired after a short time and need to rest. This leads to a waste of manpower and effective working time, delays the project, and increases labor costs.

[0003] In view of this, embodiments of this application provide an auxiliary device for cleaning the walls of metal storage tanks, which is used to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model is to design an auxiliary device for cleaning the wall of a metal storage tank, including a moving module. The moving module includes a first baffle and a second baffle located on both sides of the edge of the storage tank wall. A roller supporting the edge of the storage tank wall is provided between the first baffle and the second baffle. An elastic traction component for suspending a grinder is provided on the first baffle.

[0005] In some embodiments, the first baffle and the second baffle are provided with guide wheels that support the side of the tank wall.

[0006] In some embodiments, the first baffle and the second baffle are connected by a double-ended bolt, both ends of which are fitted with nuts. The first baffle and the second baffle are clamped between the two nuts, and the roller is rotatably mounted on the bolt shank of the double-ended bolt.

[0007] In some embodiments, the roller includes two opposing rolling rings that are rotatably fitted onto the rod of the double-ended bolt, and an elastic restoring element is supported between the two rolling rings.

[0008] In some embodiments, tapered flanges are provided at the relatively distant ends of the two rolling rings.

[0009] In some embodiments, the elastic reset element is a cylindrical spring fitted onto the double-ended bolt.

[0010] In some embodiments, the elastic traction member includes a spring connected to the first baffle and a connecting rope connected to the spring.

[0011] In some embodiments, the connecting rope comprises upper and lower sections connected by a telescopic adjustment member.

[0012] In some embodiments, the telescopic adjustment member includes an O-ring, with threaded holes at both ends of the O-ring, and threaded rods connected to the threaded holes at the ends of the upper and lower sections of the rope.

[0013] In some embodiments, the lower end of the rope is provided with a through hole for the binding strap to pass through.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes a movable module and elastic traction component that can move along the tank wall to assist manual traction of the grinder from above, minimizing worker fatigue, shortening rest time, and improving the efficiency of cleaning weld seams in metal storage tanks. It also significantly reduces the weight of the angle grinder held by the worker, thus reducing arm fatigue. The distance between the two steel plates can be adjusted with bolts, making it suitable for grinding weld seams in metal storage tank walls of different thicknesses, and it can be reused multiple times.

[0019] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0020] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0021] like Figure 1 As shown, an auxiliary device for cleaning the wall of a metal storage tank includes a moving module. The moving module includes a first baffle 1 and a second baffle 2 located on opposite sides of the edge of the tank wall panel 3. Rollers supporting the edge of the tank wall panel 3 are disposed between the first baffle 1 and the second baffle 2. An elastic traction element for suspending a grinder is provided on the first baffle 1. The first baffle 1 and the second baffle 2 can simply be two steel plates. The grinder can be, for example, an angle grinder. The angle grinder is used to clean the weld root of the weld seam 301.

[0022] In use, the rollers are supported on the upper edge of the tank wall panel 3. The first baffle 1 and the second baffle 2 are located on both sides of the edge of the tank wall panel 3. The two steel plates mainly serve to fix the device, preventing it from tipping over. The angle grinder is connected to the elastic traction component, which provides an upward auxiliary pulling force to the angle grinder, reducing the strain on the worker's hands. The elastic traction component has a certain elasticity, allowing it to have a certain elastic extension and contraction length to adapt to different grinding distances. The elastic traction component can pull the moving module along the edge of the tank wall panel 3 to facilitate grinding and cleaning of different areas. The rollers facilitate the movement of the moving module along the edge of the tank wall panel 3.

[0023] This approach minimizes the weight of the angle grinder in the worker's hand, reduces arm fatigue, and shortens rest time. The reduced weight on the arm also improves work efficiency.

[0024] The first baffle 1 and the second baffle 2 are provided with guide wheels 4 that support the side of the tank wall 3, so that the first baffle 1 and the second baffle 2 can move smoothly along the tank wall 3 and reduce friction.

[0025] The first baffle 1 and the second baffle 2 are connected by a double-ended bolt 5, with nuts 6 fitted at both ends of the double-ended bolt 5. The first baffle 1 and the second baffle 2 are clamped between the two nuts 6, and the roller is rotatably mounted on the bolt shank of the double-ended bolt 5. The distance between the first baffle 1 and the second baffle 2 can be adjusted by adjusting the distance between the two nuts 6, thus adapting to the use of tank wall panels 3 of different thicknesses.

[0026] The roller includes two opposing rolling rings 7, which rotatably mount on the rod of the double-ended bolt 5. An elastic restoring element supports the two rolling rings 7, thus allowing the support width of the roller to vary with the distance between the first baffle 1 and the second baffle 2. Furthermore, the relatively distant ends of the two rolling rings 7 are provided with tapered flanges. These tapered flanges facilitate the rolling rings 7 to be engaged with the sides of the tank wall plate 3, preventing the tank wall plate 3 from contacting the first baffle 1 and the second baffle 2. The elastic restoring element can be a cylindrical spring 8 mounted on the double-ended bolt 5. The diameter of the cylindrical spring 8 is smaller than the diameter of the rolling rings 7.

[0027] The elastic traction component includes a connecting spring 9 connected to the first baffle 1 and a connecting rope connected to the connecting spring 9. The connecting rope may be, for example, a steel wire rope.

[0028] The connecting rope comprises upper and lower sections, with the upper section 10 and lower section 11 connected by a telescopic adjustment mechanism. In this embodiment, the telescopic adjustment mechanism includes an O-ring, with screw holes 12 at both ends. Screws 13, connected to the screw holes 12, are located at the ends of the upper and lower sections. The connecting portion of the O-ring on both sides of the screw holes 12 is an arc-shaped metal strip 14. This arc-shaped metal strip 14 allows the O-ring to have a certain elastic expansion and contraction capacity under the tension of the upper and lower sections, effectively functioning as a connecting spring 9. The length of the connecting rope can also be finely adjusted by rotating the screws 13 relative to the screw holes 12.

[0029] The lower section of the rope 11 has a through hole at its end for the binding strap 15 to pass through, so that the angle grinder can be bound by the binding strap.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
