Technical Field

[0001] The invention belongs to the technical field of steel repair, and in particular relates to a steel grinding tool and method. Background Art

[0002] At present, cracks in round steel flaw detection materials basically need to be manually ground. Since the surface cracks are as thin as hair, the more they are ground, the thinner they become. It is difficult to see with the naked eye whether they have been ground in place after grinding. There are often cases where cracks are not ground cleanly. After adding lighting to each finishing table, the light effect is better and is conducive to crack inspection. However, it is still difficult to see with the naked eye whether the cracks are ground clean at a place far away from the light on the finishing table, resulting in frequent problems of cracks not being ground clean.

[0003] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0036] like Figure 1-5As shown, a steel grinding tool is used to reflect light to the workpiece to be ground during the grinding operation to observe cracks and improve the grinding quality. It specifically includes a glove 1 and a reflector. When performing the grinding operation, the operator wears the glove 1 on the hand, and the reflector is detachably connected to the side of the glove 1 corresponding to the back of the hand; the reflector has a reflective surface, which is an arc-shaped surface and is located on the side of the reflector away from the glove 1. During the grinding operation, the light source can be reflected to the grinding position through the reflective surface at the back of the hand. The arc-shaped reflective surface can better concentrate the light source, which is convenient for improving the brightness of the reflected light source and facilitating the observation of cracks. The light source angle can be flexibly adjusted through the reflector, the structure is simple, and it can be flexibly carried to reflect the finishing table light to improve the lighting conditions during the steel grinding operation.

[0037] In another optional embodiment, the reflective element is a tile-shaped plate 2 adapted to the back of the hand area corresponding to the glove 1. For example, the reflective element can be an aluminum reflective plate. The reflective surface can have a high reflective ability through fine grinding. At the same time, the aluminum reflective element can have a high strength and service life, and can be ground for a long time in a poor environment. In this embodiment, the reflective surface is a reflective coating attached to the reflective element, such as a reflective sticker, and the reflective coating can be replaced when it is worn.

[0038] In another optional embodiment, the reflector is a smooth aluminum reflector. The size of the aluminum reflector is about 100×120 mm, which is close to the back of the hand and is convenient to carry. The smooth aluminum plate is easy to obtain and can be used as a good light source reflection device. Of course, the reflector can also be made of elastic material, such as a plastic plate or a rubber plate.

[0039] In another optional embodiment, the reflector is provided with a first connector 3 near the finger of the glove 1 and is connected to the finger of the glove 1 in a detachable manner; the reflector is provided with a second connector 4 near the wrist of the glove 1 and is connected to the wrist of the glove 1 in a detachable manner. The reflector is fixed to the back of the hand by the first connector 3 and the second connector 4, and does not affect the grip of other grinding tools during the grinding operation. In this embodiment, the first connector 3 is an annular sleeve corresponding to the finger of the glove 1. Specifically, two perforations are provided on the edge of the reflector, and the first connector 3 passes through the perforations to connect with the reflector. In order to improve the connection effect of the first connector 3, the annular sleeve is made of elastic material, such as rubber material, and can be specifically a rubber band, so as to tighten the finger of the glove 1 by shrinking, and ensure the stability of the connection of the reflector by shrinking; in another optional embodiment, the first connector 3 can also be a cable tie, which passes through the two perforations and is clamped on the finger and tightened. Preferably, the first connector 3 is connected to the middle finger. The second connecting member 4 is a lace, which is tied to the wrist of the glove 1, such as a rope, a cable tie, a cloth belt, a steel wire, etc. In another optional embodiment, the second connecting member 4 can also be a snap, a buckle, a magic stick, etc., which can be selected according to actual needs.

[0040] In another optional embodiment, the reflector can also be a disk 6, and the size of the disk 6 corresponding to the reflector matches the area of ​​the back of the hand to avoid affecting other grasping operations of the operator, and the side of the reflector corresponding to the glove 1 is a smooth curved surface 62 that matches the back of the hand of the glove 1. The smooth curved surface 62 should meet the principles of ergonomics and fit closely with the back of the hand through the smooth curved surface 62 to ensure comfort during use. When the reflector is circular, the arc surface is set in the middle of the reflector, and the two sides of the arc surface smoothly transition to the reflector. The axial direction corresponding to the arc surface is preferably the same as the direction from the wrist to the fingers.

[0041] In another optional embodiment, a holder 5 corresponding to the connection surface is provided at the back of the hand of the glove 1, and the reflector is detachably connected to the holder 5. The holder 5 is an open tubular structure, and a smooth end surface is provided near the back of the hand of the glove 1. The smooth end surface conforms to the ergonomic principle and fits the curved surface of the back of the hand of the operator. The reflector faces the open end of the holder 5 and is installed in the holder 5. After being installed in the holder 5, the reflector fits the back of the hand through the smooth curved surface 62 on the reflector.

[0042] In this embodiment, the holder 5 and the reflector are interference fit, which can ensure that the reflector is not easy to fall off. Alternatively, a slot is provided on the inner wall of the holder 5, and a limiting protrusion corresponding to the slot is provided on the outer wall of the holder 5, so as to limit the reflector in the axial direction and prevent the reflector from falling off.

[0043] In another optional embodiment, the holder 5 and the reflective element are both made of rubber material. The rubber material has good deformation ability and can ensure the comfort of the operator. In this embodiment, the holder 5 can be connected to the glove 1 by gluing or sewing, or the glove 1 is also made of rubber material, and the holder 5 and the glove 1 are an integrally molded structure.

[0044] In another optional embodiment, the holder 5 extends to the side away from the glove 1 to form a skirt corresponding to the reflective element. Since the working environment of the grinding process is relatively complex, the reflective element is easily bumped, especially the reflective surface 61 will reduce the reflective effect after being bumped. Therefore, the upper edge of the reflective element is extended upward by the skirt to prevent the reflective surface 61 from being bumped, thereby protecting the reflective element. In order to facilitate observation and increase the range of the reflective surface 61 receiving the light source, a plurality of notches can be evenly distributed on the skirt.

[0045] The length of the skirt plate extending from the upper edge of the reflective member (vertically away from the back of the hand) should not be too large or too small, preferably 1 cm, and the notch can be an arc notch or a rectangular notch.

[0046] The reflective surface is a reflective coating attached to the reflective element, and the reflective coating is preferably a reflective sticker.

[0047] In another optional embodiment, the present invention also provides a method for grinding steel using the above-mentioned grinding tool, specifically comprising: step S1, the operator wears the glove 1 on the hand; step S2, connecting the reflector to the side of the glove 1 corresponding to the back of the hand; step S3, the reflector has a reflective surface, and the relative angle between the reflective surface and the light source is adjusted to reflect the light source through the reflective surface to the crack of the workpiece to be ground; step S4, grinding the crack on the workpiece to be ground, and observing the crack after grinding through the reflected light source until the crack on the workpiece to be ground is eliminated.

[0048] Specifically, before performing the grinding operation, a suitable and easily available lighting source should be selected. Generally speaking, the most easily available lighting source at the steel finishing site is the light above the finishing table. After wearing the glove 1 on the hand, connect the reflector to the back of the hand. When it is necessary to observe the crack, adjust the relative angle between the reflective surface and the light source, and reflect the light source through the reflective surface to the crack of the workpiece to be ground to observe the crack. When performing steel grinding operations, according to safety operation standards, you need to wear labor protection gloves 1, wear goggles, and hold the handheld grinder with both hands, and set the reflector on the back of the hand without affecting the operation of the grinder.

[0049] The finishing table light is reflected through the reflective surface to illuminate the surface of the steel. If there are surface cracks that have not been cleaned up, the surface cracks can be effectively identified after the lighting conditions are improved (surface cracks are black lines). After the reflected light source inspection, the surface cracks can be fully inspected without the need for manual flaw detection and confirmation. The surface cracks that have been found can be repaired using a handheld grinder. After completion, the above operation method can be repeated for review. It can be understood that the above description is only exemplary and is not limited to this in the embodiments of the present application.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
