Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion engineering, and in particular to a rust removal tool for crevices in structures. Background Technology

[0002] Rust forming in the crevices of steel structures is difficult to remove deeply using conventional tools due to the limited space, especially in steel structures within chemical plant areas. Residual rust not only prevents effective surface treatment and protection of the rusted areas but also accelerates the corrosion rate of the steel structures, severely shortening their overall service life.

[0003] Therefore, it is necessary to design a special rust removal tool for rust in crevices. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a rust removal tool for gaps in structures. This tool has a simple structure, low processing cost, and facilitates maintenance personnel in efficiently cleaning rust from gaps in steel structures, thus meeting the needs of maintenance operations.

[0005] The technical solution of this utility model is: a rust removal tool for gaps in structures, comprising a strip of metal, wherein the two sides of the middle part of the strip of metal are provided with a number of unidirectional teeth along the length direction to form a rust removal surface, and a number of serrations are provided on one long side of the strip of metal corresponding to the edge of the rust removal surface to form a slit edge, and the two ends of the strip of metal form a gripping section.

[0006] The ratio of the length of the rust-removed surface to the length of the strip metal is 0.55-0.6.

[0007] The side of the rust-removing surface and the side of the gripping section are connected by an inwardly recessed arc-shaped connecting section.

[0008] The extended end of the grip section is an outwardly protruding arc segment, and at least one grip section has a hanging hole in the middle.

[0009] At least one grip section is provided with a through hole, such that the area between the through hole and the arc segment of the grip section forms a grip handle.

[0010] The strip-shaped metal strip is a carbon structural steel strip.

[0011] The unidirectional teeth on the two rust-removed surfaces face the same direction, and the tooth height of the unidirectional teeth is 1.5mm and the tooth length is 5.0mm.

[0012] The saw teeth have a tooth height of 3mm and a tooth length of 5mm.

[0013] The above technical solution has the following beneficial effects:

[0014] 1. The rust removal tool for structural crevices includes a strip of metal serving as the basic structure, ensuring structural strength and facilitating reciprocating movement through structural crevices for rust removal. Both sides of the strip have several unidirectional teeth along its length, forming a rust-removing surface. As the strip reciprocates through the crevices, the unidirectional teeth on the rust-removing surface remove rust from the crevices, achieving efficient rust removal. One long side of the strip, corresponding to the rust-removing surface, has several serrated edges, forming a slit edge. When maintenance personnel continuously remove rust along the length of the structural crevices, this slit edge separates rust or impurities blocking the crevices, allowing the strip to move along the length of the crevices for continuous rust removal, greatly improving the efficiency of rust removal from structural crevices. Both ends of the strip form grip sections, allowing maintenance personnel to hold and manipulate the metal strip to efficiently complete the rust removal work in the structural crevices.

[0015] 2. The side of the rust-removing surface and the side of the grip section are connected by an inwardly recessed arc section, forming a limit reminder section without affecting the normal use of the tool, thus reducing the risk of injury to maintenance personnel.

[0016] 3. The extended end of the grip section is an outwardly protruding arc segment to avoid the risk of injury. At least one grip section has a hanging hole in the middle for easy tool storage. At least one grip section has a through hole, so that the area between the through hole and the arc segment of the grip section forms a grip handle, allowing maintenance personnel to hold the tool on the grip handle for easy operation and force application.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0022] In the attached diagram, 1 is a strip of metal, 2 is a one-way tooth, 3 is a rust-removed surface, 4 is a serration, 5 is a slotted edge, 6 is a grip section, 7 is a hanging hole, 8 is a through hole, and 9 is a grip handle. Detailed Implementation

[0023] See Figures 1 to 4This is a specific embodiment of a rust removal tool for crevices in structures. The rust removal tool for crevices in structures includes a strip of metal 1. Specifically, the strip of metal is made of Q235B, with a thickness of 5mm, a width of 40mm, and a length of 380mm. Several unidirectional teeth 2 are arranged along the length of both sides of the middle section of the strip of metal, forming a rust removal surface 3. The length of the rust removal surface is 200mm, and the unidirectional teeth on both rust removal surfaces face the same direction. Specifically, the tooth height of the unidirectional teeth is 1.5mm, the tooth length is 5.0mm, and the angle between one edge of the unidirectional tooth and the strip of metal is 90°, while the angle between the other edge of the tooth and the strip of metal is 107°. A strip of metal 1 has several serrations 4 along one long side corresponding to the edge of the rust-removing surface 3, forming a slotted edge 5. Specifically, the serrations have a tooth height of 3mm and a tooth length of 5mm. One tooth edge of the serration forms a 90° angle with the long side, and the other tooth edge forms a 60° angle with the long side. The two ends of the strip of metal form grip sections 6. In this embodiment, the side of the rust-removing surface 3 and the side of the grip section 6 are connected by an inwardly concave arc connecting section, and the extension end of the grip section 6 is an outwardly convex arc section. A hanging hole 7 is provided in the middle of the left grip section, and a through hole 8 is provided on the right grip section 6, so that the area between the through hole and the arc section of the grip section forms a grip handle 9.

[0024] The working principle of this utility model is as follows: the maintenance personnel control the rust removal tool to pass through the gap in the steel structure by holding the handle with one hand, and then hold the other end of the handle with the other hand to pull the rust removal tool back and forth through the gap to remove the rust in the gap. At the same time, the rust removal tool is also driven to move along the length of the gap and pass through the gap back and forth to achieve continuous rust removal of the gap.
