Description
Technical Field
[0001] This application belongs to the field of rust removal technology, specifically relating to a rust removal device. Background Technology
[0002] Steel is an essential material in coking plants; pipes, platforms, pipe racks, ladders, and other structures are all made of steel. Considering cost issues and the company's cost-saving and efficiency-enhancing philosophy, carbon steel is typically used. During use, steel components are usually joined together using welding technology. Because carbon steel is highly prone to rust, the welding area needs to be ground and rust-removed before welding to ensure welding quality (if painting for corrosion protection is required, the entire steel structure needs to be ground and rust-removed). Traditional rust removal methods mostly involve manually grinding the steel surface with a handheld angle grinder, which is highly dangerous. Slight improper operation can cause mechanical injury, and the sparks generated during grinding pose a fire hazard. Summary of the Invention

Detailed Implementation
[0025] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0026] Please see Figure 1 and Figure 2 According to a first aspect of this application, a rust removal device 100 is provided, including a bracket 110, a first adjusting assembly 120, a second adjusting assembly 130, a rust removal mechanism 140, and fasteners 150. The bracket 110 includes a frame 111 and two protective plates 112 connected to the frame 111. The two protective plates 112 are located on both sides of the frame 111 along a first direction, so that the two protective plates 112 enclose a protective area. The protective area has openings on both sides along a second direction for the rust-removing parts to pass through. The first adjusting assembly 120 includes a first connecting member 121 and a first sliding member 122. The first connecting member 121 is connected to the frame 111 and extends along the first direction. The first sliding member 122 is slidably engaged with the first connecting member 121 along the first direction. The second adjusting assembly... 130 includes a second connector 131 and a second slider 132 arranged side by side and connected to each other along a second direction, the second connector 131 being connected to the first slider 122; and a rust removal mechanism 140 including a brush handle 141 and a rust removal assembly 142 connected to the brush handle 141, the brush handle 141 and the second slider 132 slidingly engaging along a third direction; the brush handle 141 being located in a protected area; and a fastener 150 acting on the brush handle 141, the second slider 132, the second connector 131, the first slider 122, and the first connector 121 to lock the brush handle 141, the second slider 132, the second connector 131, the first slider 122, and the first connector; wherein the first direction, the second direction, and the third direction are mutually perpendicular.
[0027] Two protective plates 112 are provided, and the two protective plates 112 are arranged opposite each other along the first direction; the protective plates 112 can be made of metal materials, such as steel plates, aluminum alloys, etc., to reduce sparks from being splashed during the grinding process. They can effectively resist sparks from being splashed during the grinding process, reduce external impact and chemical corrosion, and improve the ability to adapt to different environments and working conditions.
[0028] In some embodiments, the distance between the two protective plates 112 along the first direction is greater than the width of the part to be derusted. That is, the length of the part to be derusted, such as steel, is placed along the second direction, and the width of the steel is placed along the first direction. This facilitates the movement of the derusting device 100 to grind different areas of the steel, while the two protective plates 112 also provide protection.
[0029] During use, first place the part to be derusted, such as steel, under the derusting device 100 along the second direction and fix it. Then, push the derusting device 100 to one end of the steel. Adjust the derusting component 142 under the brush handle 141 to the appropriate position along the first and third directions respectively. Secure the brush handle 141, the second sliding member 132, the second connecting member 131, the first sliding member 122, and the first connecting member with a fastener 150. The operation is convenient. Turn on the derusting component 142 to perform grinding and derusting. After the grinding and derusting of this area is completed, push the device along the second direction or continue to adjust the position of the derusting component 142 to adjust the grinding and derusting position.
[0030] The rust removal device 100 of this application has a simple design, with the rust removal components located in a protected area to reduce sparks during grinding and lower the probability of fire. It is easy to operate, safe, and highly efficient, and suitable for grinding and removing rust from most types of steel.
[0031] In some embodiments, one of the first connecting member 121 and the first sliding member 122 is provided with a first sliding groove 1211, and the other is provided with a first sliding block 1221 that cooperates with the first sliding groove 1211. That is, the position of the rust removal mechanism 140 along the first direction can be adjusted by the sliding engagement of the first sliding member 122 with the first connecting member 121.
[0032] In some embodiments, the first connecting member 121 is provided with a first sliding groove 1211, and the first sliding member 122 is provided with a first slider 1221. That is, the position of the rust removal mechanism 140 along the first direction can be adjusted by the sliding engagement of the first slider 1221 of the first sliding member 122 with the first sliding groove 1211 on the first connecting member 121. The first connecting member 121 is connected to the frame 111, and the sliding groove on the first connecting member 121 and the sliding member 122 are designed to slide, ensuring the stability of the overall movement.
[0033] In some embodiments, the first connector 121 has first grooves 1211 at both ends along a third direction, and the first slider 122 has the same number of first sliders 1221 as the first grooves 1211 and corresponding to each other. The brush handle 141 can be adjusted in the first direction by sliding the first sliders 1221 with the corresponding first grooves 1211.
[0034] To ensure the stability of the sliding of the first sliding member 122 and the first connecting member 121, in some embodiments, the first sliding member 122 includes a first connecting block, a second connecting block, and a connecting part that is connected to both the first connecting block and the second connecting block. The first connecting block and the second connecting block are symmetrical along a third direction. The first connecting block, the connecting part, and the second connecting block together form an inverted U-shape. The first connecting block and the second connecting block are each provided with a first slider 1221. The first slider 1221 is slidably connected to the corresponding first sliding groove 1211. That is, the first sliding part is hung on the first connecting member 121 and slidably connected to the first connecting member 121, thus ensuring the stability of the overall connection.
[0035] In some embodiments, the first slider 122 is at least partially sleeved outside the first connector 121 and slides in cooperation with the first connector 121. By at least partially sleeved outside the first connector 121, the first slider 122 increases the contact area between the first slider 122 and the first connector 121 while ensuring that the first slider 122 can slide along the first connector 121. This results in better stability compared to the case where the first groove 1211 is provided in the first direction of the first connector 121.
[0036] In some embodiments, one of the brush handle 141 and the second slider 132 is provided with a second sliding groove, and the other is provided with a second slider that cooperates with the second sliding groove. That is, the position of the rust removal mechanism 140 in a third direction can be adjusted by the sliding cooperation between the second slider 132 and the second connector 131.
[0037] In some embodiments, the second slider 132 is provided with a second slider, and the brush handle 141 is provided with a second groove. That is, the position of the rust removal mechanism 140 along a third direction can be adjusted by the sliding engagement of the second slider of the second slider 132 with the second groove on the brush handle 141. Specifically, the brush handle 141 has a groove along a third direction, and the second slider 132 is provided with a second slider, which slides in engagement with the brush handle 141.
[0038] In some embodiments, to simplify the connection structure and improve the stability of the connection, the second sliding member 132 has an internally hollow cylindrical structure, and the brush handle 141 has a columnar structure, with the second sliding member 132 sleeved on the outside of the brush handle 141. In some embodiments, the cross-section of the brush handle 141 is circular, and the second sliding member 132 has a circular hole, allowing the brush handle 141 to pass through and slide in cooperation with the second sliding member 132.
[0039] To ensure connection stability and ease of adjustment, in some embodiments, the brush handle 141 is detachably connected to the first connector 121 via a fastener 150.
[0040] In some embodiments, along a first direction, the first connector 121 is provided with a plurality of first adjustment holes 1212; along a second direction, the first slider 122, the second connector 131, and the second slider 132 are respectively provided with a first connection hole, a second connection hole, and a third connection hole; along a third direction, the brush handle 141 is provided with a plurality of second adjustment holes 1411; the third connection hole, the second connection hole, and the first connection hole are coaxially connected to form a connecting hole, the connecting hole being operably coaxially connected to any of the second adjustment holes 1411, and the connecting hole being operably coaxially connected to any of the first adjustment holes 1212; the fastener 150 extends into the connecting hole and the first adjustment holes 1212 and the second adjustment holes 1411 coaxially connected to the connecting hole. It should be noted that the fastener 150 can be a bolt, nut, or washer, etc. A bolt is a straight rod with a threaded end and a protruding limit at the other end; a nut is a component with a threaded hole, used in conjunction with a bolt; a washer is annular in shape and is typically placed between the bolt and the connecting material to increase friction and reduce vibration. This ensures that the fastener 150 can meet the connection requirements after the adjustment mechanism's position is adjusted. In other words, a single bolt and nut can be used to lock the brush handle 141 to the first connector 121, making operation convenient.
[0041] Therefore, once the first adjusting member's position in the first direction is adjusted and the brush handle 141's position in the third direction is adjusted, the bolt is inserted into the second adjusting hole 1411, the third connecting hole, the second connecting hole, the first connecting hole, and the first adjusting hole 1212. Then, the nut and bolt are engaged to connect and fix the brush handle 141 to the second sliding member 132, the second connecting member 131, the first sliding member 122, and the first connecting member 121. Conversely, by loosening the nut until the bolt does not penetrate the first adjusting hole 1212, the first adjusting member's position in the first direction can be adjusted. By further loosening the nut until the bolt does not penetrate the third connecting hole, the second connecting hole, the first connecting hole, and the second adjusting hole 1411, the brush handle 141's position in the third direction can be adjusted, which is equivalent to adjusting the horizontal and vertical positions of the rust removal mechanism 140.
[0042] In some embodiments, pulleys 113 are also provided at the bottom of the two protective plates 112. That is, pulleys 113 are installed at each of the four corners of the bottom of the protective plate 112, i.e., four pulleys 113 are installed to realize the movement function of the adjustment mechanism. The pulleys 113 are installed at the bottom of the protective plate 112 as support and moving parts. A pulley 113 typically consists of a wheel, a bracket 110, and an axle. The wheel is the core part of the pulley 113, responsible for rolling on the ground. The bracket 110 is used to fix the pulley 113 and provide stability. The axle connects the wheel and the bracket 110, allowing the wheel to rotate freely. In other embodiments, the sliding plate has a locking structure, which can lock the pulley 113 to prevent it from moving. For example, the locking structure is a foot pedal lock, which is operated by the foot pedal to make the locking mechanism contact the pulley 113, thereby achieving locking. This application does not impose special limitations on the structure of the pulley 113.
[0043] In some embodiments, the rust removal assembly 142 includes a motor, a rotating structure, and a wire brush. The motor is connected to the brush handle 141, and the output end of the motor is connected to a rotary joint. The rotating structure is equipped with a wire brush for rust removal. The drive motor can drive the wire brush to rotate, thereby removing rust from the steel.
[0044] During use, first place the part to be derusted, such as steel, under the derusting device 100 along the second direction and fix it. Then push the derusting device 100 to one end of the steel. By loosening the fastener 150, move the first sliding member 122 and the brush handle 141 to adjust the derusting component 142 to a suitable position. Turn on the derusting component 142 to grind and remove rust. After the area is ground and derusted, push the device forward along the second direction or continue to adjust the position of the derusting component 142 to adjust the grinding and derusting position.
[0045] The rust removal device 100 of this application is provided with a first adjustment component 120 and a second adjustment component 130, which can realize the vertical and horizontal movement of the rust removal component 142; the rust removal device 100 is provided with protective plates 112 on both sides to reduce the sparks splashing during the grinding process and reduce the probability of fire accidents; grinding does not require hand tools, only the position of the wire brush needs to be adjusted and the device can be pushed to achieve grinding and rust removal, which significantly improves the safety and efficiency of grinding.
[0046] In some embodiments, along the second direction, the first connector 121 is provided with a plurality of first adjustment holes 1212, and the first slider 122, the second connector 131 and the second slider 132 are provided with a first connection hole, a second connection hole and a third connection hole in sequence; along the third direction, the brush handle 141 is provided with a plurality of second adjustment holes 1411; the third connection hole, the second connection hole and the first connection hole correspond to and cooperate with one of the second adjustment holes 1411 and one of the first adjustment holes 1212.
