Description

Technical Field

[0001] This utility model relates to the field of rust removal technology, specifically to a portable steel structure rust removal device. Background Technology

[0002] During the installation of steel structures, their surfaces are highly susceptible to corrosion due to prolonged exposure to the natural environment. This not only affects the appearance of the steel structure but also shortens its service life. Therefore, rust removal is a crucial step in ensuring the safe and stable operation of steel structures. Currently, the commonly used equipment for rust removal of steel structures, especially for profiles such as square tubes, is a grinder with a wire brush. Operators use a handheld grinder, employing a high-speed rotating wire brush to contact the surface of the square tube and remove rust through friction. However, this traditional rust removal method has significant limitations. Because square tubes have four mutually perpendicular surfaces, operators must grind and remove rust from each surface individually, making simultaneous grinding of two surfaces impossible. This not only increases the labor intensity of operators but also leads to low efficiency in rust removal, making it difficult to meet the needs of large-scale steel structure rust removal operations. Utility Model Content

[0003] The main purpose of this utility model is to provide a portable steel structure rust removal device to solve the problem that in the existing technology, operators need to grind and remove rust from each surface one by one, and it is impossible to achieve simultaneous grinding of two surfaces.

[0004] To achieve the above objectives, this utility model provides a portable steel structure rust removal device, including a U-shaped frame and a lifting block; Movable arms are provided on both sides of the U-shaped frame, and a push rod is fixed on the top wall. Two limiting rods are fixedly arranged in the horizontal direction of the U-shaped frame. Each of the movable arms has a transverse through slot along the horizontal direction and a notch in the middle. The two limiting rods correspond one-to-one with the two transverse through slots and are located inside the transverse through slots. The notch is hinged to two connecting rods along the length of the movable arm, the bottom end of the movable arm is detachable from the main body of the grinder, and the main body of the grinder is detachable from the wire reel; The two wire reels are arranged opposite each other; The lifting block has a notch and is connected to a lifting mechanism for driving its lifting. The ends of the two connecting rods away from the movable arm are respectively hinged to the notch.

[0005] Preferably, the U-shaped frame includes a top plate and two parallel vertical plates fixedly disposed at both ends of the top plate; The two ends of the two limiting rods are respectively fixed to the two vertical plates; The two vertical plates have vertical grooves on their opposite sidewalls, and the two ends of the lifting block are respectively embedded in the two grooves.

[0006] Preferably, each vertical plate has a roller at the end away from the top plate, and the axial direction of the roller is consistent with the axial direction of the wire reel.

[0007] Preferably, the push rod is a telescopic rod.

[0008] Preferably, the lifting mechanism includes a bearing and a first bolt, and the top plate has a first threaded hole through it; The outer ring of the bearing is fixedly connected to the top of the lifting block; The first bolt is screwed into the first threaded hole, and one end is fixedly connected to the inner ring of the bearing.

[0009] Preferably, a through-hole is formed at the bottom of each of the movable arms; Each of the perforations is fitted with a clamping device, the clamping device comprising a metal arc plate and a second bolt; The two ends of the metal arc plate are fixed with bearing plates, each bearing plate passes through a second threaded hole, and the second bolt passes through the two second threaded holes to screw a nut. The metal arc-shaped plate is fixedly mounted on the connecting plate, and the connecting plate is fixedly mounted on the movable arm; The head of the grinding machine body is tied to the metal arc plate, and the wire reel is transferred through the perforation.

[0010] Preferably, the metal arc plate is made of stainless steel.

[0011] The beneficial effects of the above scheme are: Before starting the operation, the operator adjusts the height of the lifting block according to the dimensions of the square tube using the lifting mechanism. When the lifting block rises, its notch drives the two connecting rods hinged to it to rotate upwards. Since the other end of the connecting rod is hinged to the notch of the movable arm, and the movable arm is fitted onto the limiting rod of the U-shaped base frame through a transverse through-slot, the two movable arms will move inwards along the limiting rod under the pull of the connecting rod. Conversely, if the lifting block descends, the connecting rod will push the movable arm outwards along the limiting rod until the distance between the two wire discs matches the two opposite surfaces of the square tube to be derusted. After adjustment, the two grinding machine bodies are started, causing the wire discs to rotate at high speed. The operator holds the push rod on the top wall of the U-shaped base frame, aligns the equipment with the square tube, and makes the two oppositely positioned wire discs fit against the two opposite surfaces of the square tube. Then, the operator pushes the U-shaped base frame along the length of the square tube. During the movement, the high-speed rotating wire discs continuously contact and rub against the surface of the square tube, simultaneously removing rust from both surfaces.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0016] like Figures 1-4 As shown, this embodiment provides a portable steel structure rust removal device, including a U-shaped frame 10 and a lifting block 50. Movable arms 20 are respectively installed on both open sides of the U-shaped frame 10, and a push rod 30 is fixed to the top wall of the U-shaped frame 10. Two limiting rods 11 are fixedly arranged horizontally along the U-shaped frame 10. The push rod 30 is a telescopic rod. The telescopic rod body adopts existing technology in this invention, so it will not be described in detail. The structural design of the telescopic rod body is adapted to the needs of different users. Figure 2As shown, each of the movable arms 20 has a horizontal through slot 21, and each of the movable arms 20 has a notch 22 in the middle. Two limiting rods 11 correspond one-to-one with the two horizontal through slots 21 and are located within the horizontal through slots 21. Two connecting rods 40 are hinged to the notch 22 along the length direction (which can be considered vertical) of the movable arm 20. The bottom end of the movable arm 20 is detachable from the grinding machine body 1, as shown... Figure 4 As shown, the main body 1 of the grinder has a detachable wire reel 2. It should be noted that both the main body 1 and the wire reel 2 utilize existing technology, so further details are omitted. The main body 1 can be a Bosch GWS 6-100C, Makita 9557NB, or Dongcheng FF03-100. The wire reel 2 has a bowl-shaped or disc-shaped structure. Two wire reels 2 are arranged opposite each other. The lifting block 50 has a notch 51, and the lifting block 50 is connected to a lifting mechanism 52 for driving its lifting. The ends of the two connecting rods 40 away from the movable arm 20 are respectively hinged to the notch 51. The lifting mechanism 52 includes a bearing 520 and a first bolt 521. The top plate 12 has a through-hole 120. The outer ring of the bearing 520 is fixedly connected to the top of the lifting block 50. The first bolt 521 is screwed into the first threaded hole 120, and one end of the first bolt 521 is fixedly connected to the inner ring of the bearing 520.

[0017] At the start of operation, the operator needs to adjust the distance between the two wire reels 2 according to the size of the square tube 3. At this time, the height of the lifting block 50 is adjusted by rotating the first bolt 521 on the top plate 12 of the U-shaped base frame 10. Since the first bolt 521 is screwed into the first threaded hole 120 of the top plate 12, and one end of it is fixed to the inner ring of the bearing 520 fixedly connected to the top of the lifting block 50, when the first bolt 521 is rotated clockwise, the first bolt 521 will move downward along the first threaded hole 120. At the same time, under the action of the bearing 520, the lifting block 50 is prevented from rotating with the bolt, and only the lifting block 50 is driven to descend vertically. When the first bolt 521 is rotated counterclockwise, the first bolt 521 moves upward along the first threaded hole 120, thereby driving the lifting block 50 to rise vertically. As the lifting block 50 rises and falls, its notch 51 drives the two connecting rods 40 to rotate accordingly, causing the movable arm 20 to move inward or outward along the limiting rod 11 until the distance between the two wire discs 2 is appropriate for the two opposite surfaces of the square tube 3 to be derusted. After adjustment, the two grinding machine bodies 1 are started, causing the wire discs 2 to rotate at high speed. The operator holds the push rod 30, aligns the equipment with the square tube 3, and makes the two opposite wire discs 2 fit against the two opposite surfaces of the square tube 3 respectively. Then, the U-shaped base frame is pushed to move along the length of the square tube 3, and the wire discs 2 simultaneously remove rust from the two surfaces of the square tube 3. If it is necessary to change the rust-removed surface of the square tube 3, after stopping the equipment, the height of the lifting block 50 is adjusted again by rotating the first bolt 521 to change the distance between the wire discs 2 to fit the new surface, and the above pushing operation is repeated. When it is necessary to replace the wire discs 2 or repair the grinding machine body 1, the disassembly operation can be performed in the original manner.

[0018] Before starting the operation, the operator first adjusts the height of the lifting block 50 according to the dimensions of the square tube 3 using the lifting mechanism 52. When the lifting block 50 rises, its notch 51 will drive the two connecting rods 40 hinged to it to rotate upwards. Since the other end of the connecting rod 40 is hinged to the notch 22 of the movable arm 20, and the movable arm 20 is fitted onto the limiting rod 11 of the U-shaped base frame through the transverse through-slot 21, the two movable arms 20 will move inwards along the limiting rod 11 under the pull of the connecting rod 40. Conversely, if the lifting block 50 descends, the connecting rod 40 will push the movable arm 20 outwards along the limiting rod 11 until the distance between the two wire discs 2 matches the two opposite surfaces of the square tube 3 to be rusted. After the adjustment is completed, the two grinding machine bodies 1 are started, causing the wire discs 2 to rotate at high speed. The operator holds the push rod 30 on the top wall of the U-shaped base frame, aligns the equipment with the square tube 3, and makes the two oppositely arranged wire discs 2 fit against the two opposite surfaces of the square tube 3 respectively. Subsequently, the operator pushes the U-shaped base frame along the length of the square tube 3. During the movement, the high-speed rotating wire disc 2 continuously contacts and rubs against the surface of the square tube 3, simultaneously removing rust from both surfaces of the square tube 3. Furthermore, when the wire disc 2 becomes worn or needs to be replaced with a different type, the old wire disc 2 can be directly removed from the main body 1 of the grinder and replaced with a new one. If the main body 1 of the grinder malfunctions, it can also be disassembled from the bottom of the movable arm 20 for repair or replacement.

[0019] like Figure 2 As shown, the U-shaped frame 10 includes a top plate 12 and two parallel vertical plates 13 fixedly disposed at both ends of the top plate 12. The two limiting rods 11 are respectively fixed at both ends to the two vertical plates 13. Slide grooves (not shown) are formed on the opposite sidewalls of the two vertical plates 13 in the vertical direction, and the lifting block 50 is respectively embedded and slidably disposed within the two slide grooves. A roller 60 is mounted on the end of each vertical plate 13 away from the top plate 12, and the axial direction of the roller 60 is consistent with the axial direction of the wire reel 2. The roller 60 abuts against the top wall of the square tube 3, facilitating the movement of this structure along the square tube 3. A through hole 23 is formed at the bottom of each movable arm 20. A clamping member 70 is installed at each through hole 23, and the clamping member 70 includes a metal arc-shaped plate 71 and a second bolt 72. The metal arc-shaped plate 71 has bearing plates 73 fixed at both ends, each bearing plate 73 passing through a second threaded hole, and the second bolt 72 passing through the two second threaded holes to connect to the nuts 74; the metal arc-shaped plate 71 has a connecting plate 75 fixedly attached to it, and the connecting plate 75 is fixed to the movable arm 20; the head of the grinding machine body 1 is tied to the metal arc-shaped plate 71, and the wire reel 2 is rotated through the through hole 23. The metal arc-shaped plate 71 is made of stainless steel. Fasteners that facilitate the existence of the grinding machine body 1 are provided, such as... Figure 4As shown, the head of the grinding machine body 1 has a cylindrical structure, with a rotating shaft at one end of the cylindrical structure, which is coaxially connected to the wire disc 2. The cylindrical structure of the grinding machine body 1 head is bound to the metal arc plate 71.
