Technical Field
[0001] This utility model relates to the field of steel structure maintenance technology, specifically to an auxiliary support for a grinder that facilitates rust removal from steel structures. Background Technology
[0002] In modern industry, steel structures are widely used in construction, bridges, machinery manufacturing, and many other sectors. However, steel structures, when exposed to natural or industrial environments for extended periods, are highly susceptible to oxidation and corrosion, leading to rust. Rust not only affects the appearance of the steel structure but, more seriously, reduces its strength and durability, threatening the safety and stability of the entire structure. Currently, grinding machines are one of the commonly used tools for rust removal of steel structures. However, there are many inconveniences in the rust removal process. For example, when grinding steel pipe structures or I-beams, it is necessary to bend over and hold the grinding machine for a long time, which makes it very inconvenient to use. Purchasing a grinding machine with a handle separately will increase the cost. Moreover, the grinding machine with a handle relies entirely on manual hand control and does not have a left-right guiding structure. The strength and stability of a person's hand are limited, making it difficult to ensure stable and even grinding for a long time. This leads to uneven grinding force during rust removal, with some areas being over-ground, damaging the surface of the steel structure and affecting the quality and later use of the steel structure. At the same time, in order to ensure the rust removal effect, it is usually necessary to first wipe the dust off the surface of the steel structure with a cloth to ensure the rust removal work. However, dust removal and rust removal cannot be carried out simultaneously, which leads to a decrease in work efficiency. Summary of the Invention
[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide an auxiliary support for a grinding machine that facilitates rust removal from steel structures.
[0004] The specific solution of this utility model is: an auxiliary support for a grinding machine for facilitating rust removal from steel structures, including a grinding machine. A movable structure is installed on one side of the grinding machine. The movable structure includes an N-shaped support. Both ends of the support are provided with lead screws, which are slidably connected to the support. A pulley is installed at one end of the lead screw, which can move along both sides of the steel structure. A headband is installed on the top of the support, which covers and fixes the head of the grinding machine. A connector is connected to the grinding machine, and a push rod is connected to the other end of the connector. A cleaning structure is installed on the surface of the support for cleaning dust on the path of the grinding machine.
[0005] According to the above technical solution, the grinding machine is fixed by a hairband, and the pulleys on both sides are adjusted to support and assist the grinding machine on both sides, which improves the stability of rust removal. At the same time, the rust removal is pushed by a push rod, avoiding long-term bending over work. The cleaning structure can be carried out simultaneously with the rust removal work, which improves work efficiency.
[0006] Furthermore, the cleaning structure includes a connecting rod hinged to the top of the bracket, with an N-shaped fixing block installed at the end of the connecting rod away from the bracket. The fixing block is used to place the rag and fix the rag to the fixing block with bolts. The cleaning structure has two sets arranged symmetrically.
[0007] According to the above technical solution, dust on the road can be removed by wiping with a cloth, achieving simultaneous rust removal and dust removal.
[0008] Furthermore, the lead screw is fixed by a nut for adjusting the position of the pulley.
[0009] According to the above technical solution, fixing the lead screw with a nut is convenient and quick, which improves the ease of adjusting the pulley.
[0010] Furthermore, the grinder is connected to a connector via bolts for adjusting the angle of the push rod.
[0011] According to the above technical solution, different push rod angles can be fixed according to the user's needs using bolts.
[0012] Compared with the prior art, this utility model has the following advantages: The auxiliary support for the grinding machine used for rust removal of steel structures, through a movable structure composed of a support, a lead screw, and pulleys, enables the grinding machine to move stably along both sides of the steel structure, overcoming the problem of difficulty in ensuring stability and uniformity when manually holding a grinding machine. It effectively avoids over-grinding or incomplete rust removal, thereby improving the quality of rust removal of steel structures. At the same time, the lead screw can slide and be adjusted according to the size of the steel structure, and the cleaning structure can remove dust in front of the grinding machine's path, thereby realizing simultaneous dust removal and rust removal, improving work efficiency, and demonstrating the practicality and convenience of the auxiliary support for the grinding machine used for rust removal of steel structures.

[0018] See Figure 1-4 This embodiment is an auxiliary support for a grinder used to facilitate rust removal from steel structures. It should be noted that the grinder 1 can be purchased and used directly. A movable structure is installed on one side of the grinder 1, including an N-shaped support 2. Lead screws 3 are threaded through both ends of the support 2, and the lead screws 3 can move within the through holes of the support 2. A pulley 4 is installed at one end of the lead screw 3, and the pulley 4 can move along both sides of the steel structure surface. A headband 5 is welded to the top of the support 2. It should be noted that the headband 5 is existing technology and can be purchased and used directly. The headband 5 wraps around the head of the grinder 1, serving to fix the grinder 1. Connecting parts 6 are connected to both sides of the head of the grinder 1. A push rod 7 is connected to the top of the connecting parts 6 away from the grinder 1. A cleaning structure is installed on the surface of the support 2. The cleaning structure is used to remove dust from the path of the grinder 1, thereby improving work efficiency.
[0019] Furthermore, the cleaning structure includes a connecting rod 8 hinged to the top of the bracket 2. An N-shaped fixing block 9 is integrally formed at the end of the connecting rod 8 away from the bracket 2. The fixing block 9 is used to place the wiping cloth, and the wiping cloth is fixed to the fixing block 9 by bolts. The cleaning structure has two sets and is arranged symmetrically.
[0020] Furthermore, the lead screw 3 is fixed by a nut and used to adjust the position of the pulley 4.
[0021] Furthermore, the head of the grinder 1 is provided with pre-embedded screw holes, which are then connected to the connector 6 by bolts for adjusting the angle of the push rod 7.
[0022] The working principle of this embodiment is as follows: When in use, first use the hairband 5 to fix the head of the grinder 1, then adjust the position of the pulleys 4 on both sides according to the width of the steel structure so that the pulleys 4 are in contact with the sides of the steel structure. Next, according to the user's habits, fix the connecting piece 6 at a suitable angle to the top of the head of the grinder 1 with bolts. Finally, stuff the rag into the N-shaped fixing block 9 and fix it with bolts. When in use, push the support 2 with the push rod 7 to drive the grinder 1 to remove rust. At the same time, the rag in front cleans the surface dust, so that the dust cleaning and rust removal work are carried out simultaneously.
