Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and more specifically, to a steel structure rust removal device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. The main frame of a steel structure is mostly welded from channel steel. Because channel steel is prone to oxidation during storage with oxygen and water vapor in the air, forming rust on its surface, it needs to be removed before the steel structure is processed and used in construction to avoid affecting the construction process.

[0003] Currently, sandblasting machines are commonly used for rust removal of steel structures used in construction. This requires workers to hold the sandblasting nozzle and aim it at each area of ​​the channel steel to remove rust. Since the channel steel is long and the area to be rusted is large, the workers' labor intensity is high, the efficiency of rust removal is low, and the rust removal effect is difficult to guarantee. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure rust removal device, which can drive the sandblasting nozzle of the sandblasting machine to move to various areas of the channel steel, thereby realizing the rust removal process of the channel steel, reducing the intensity of manual labor while improving work efficiency, and at the same time ensuring the rust removal effect to a certain extent.

[0005] The embodiments of the present invention are achieved through the following technical solutions: A steel structure rust removal device includes a base, a placement mechanism, a transmission mechanism, a sandblasting rust removal machine, a transmission plate, and a mounting base. The placement mechanism includes two vertical seats, both of which are arranged along the length direction of the base and located on opposite sides of the base. Each of the two vertical seats has a placement seat for placing channel steel along its own length direction on its adjacent side. The placement seats are fixed to the vertical seats by fixing rods. The transmission mechanism includes two transmission shafts, both located at opposite ends of the base, with the length direction of the transmission shafts aligned with the width direction of the base. Both ends of the shaft are provided with sprockets, and a chain is wound between the two sprockets on the same side. A drive motor is coaxially connected to one of the drive shafts. Both ends of the drive plate are provided with connecting blocks and are fixed between the two chains through the two connecting blocks. The mounting base is located below the drive plate.

[0007] Furthermore, the mounting base is rotatably mounted on the translation block via a rotating shaft, and the top of the mounting base extends above the translation block. A torsion spring is provided between the mounting base and the translation block, and the torsion spring is sleeved on the outside of the rotating shaft. Both sides of the top of the translation block are provided with abutting members that can abut against the mounting base. When the mounting base abuts against the abutting members, it can rotate around the rotating shaft as the rotation center.

[0008] Furthermore, the abutting member includes an abutting seat and an abutting rod. The abutting rod is rotatably mounted on the abutting seat. One end of the abutting rod extends out of the translation seat and can abut against the mounting seat. A compression spring is connected between the other end of the abutting rod and the translation seat. An abutting block is provided on the transmission plate above the abutting rod. When the lifting mechanism drives the translation seat to move upward, the abutting block can abut against the end of the abutting rod away from the mounting seat and drive the compression spring to compress.

[0009] Furthermore, the lifting mechanism includes a base, and lifting cylinders are provided on both sides of the base. The piston rods of the lifting cylinders are fixedly connected to the translation seat. A sliding groove is provided on the transmission plate along the width direction of the base.

[0010] Furthermore, the sliding mechanism includes a sliding motor, a gear is coaxially connected to the output shaft of the sliding motor, and a rack that meshes with the gear is fixedly arranged on the base along the length direction of the sliding groove.

[0011] Furthermore, a wiping block for removing residual rust from the channel steel is detachably provided on one side of the transmission plate. The shape of one end of the wiping block is adapted to the shape of the inner surface of the channel steel, and the shape of the other end of the wiping block is adapted to the shape of the outer surface of the channel steel.

[0012] Furthermore, the transmission plate is provided with slide rails on both sides of the wiping block, and sliding protrusions are provided on both sides of the wiping block. The sliding protrusions are slidably disposed in the slide rails one by one, and a limiting rod is provided between the two slide rails to limit the position of the sliding protrusions.

[0013] Furthermore, one of the vertical seats is provided with a limiting groove for the movement of the sandblasting pipe. The shape of the limiting groove is adapted to the movement trajectory of the sandblasting pipe. The limiting groove includes two horizontal grooves and a semi-circular groove disposed between the two horizontal grooves. The sandblasting pipe includes a first branch pipe, a second branch pipe and a connecting pipe. One end of the first branch pipe is connected to the sandblasting and rust removal machine. The second branch pipe is connected to the end of the first branch pipe away from the sandblasting and rust removal machine. One end of the connecting pipe is connected to the end of the second branch pipe away from the first branch pipe, and the other end is connected to the sandblasting nozzle.

[0014] Furthermore, the first branch pipe is provided with two limiting plates, which are located on the inner and outer sides of the vertical seat respectively; the transmission plate is provided with a plurality of fixing blocks for fixing the position of the second branch pipe.

[0015] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0016] 1.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] Example 1

[0031] The following description, in conjunction with specific embodiments, provides further details. Figures 1-7 As shown, this invention is a steel structure rust removal device, including a base 1, a placement mechanism 2, a transmission mechanism 3, a sandblasting rust removal machine 4, a transmission plate 5, and a mounting base 6. The placement mechanism 2 includes two vertical seats 21, both vertically welded to the base 1 along its length and located on opposite sides of the base 1. Each of the two vertical seats 21 has a placement seat 22 for placing channel steel along its length on its adjacent side. The placement seat 22 is welded to the vertical seat 21 by multiple fixing rods 23. When removing rust from the channel steel, the channel steel is placed between the two placement seats 22, which then provide support. The transmission mechanism 3 includes two transmission shafts 31, located at opposite ends of the base 1. The length direction is consistent with the width direction of the base 1. Both ends of the drive shaft 31 are fixedly mounted with sprockets 32. A chain 33 is wound between the two sprockets 32 on the same side. A drive motor 34 is coaxially connected to one of the drive shafts 31. Both ends of the drive plate 5 are provided with connecting blocks 51 and are fixedly mounted between the two chains 33 through the two connecting blocks 51. The mounting seat 6 is located below the drive plate 5. The drive plate 5 is provided with a translation mechanism 7 for driving the mounting seat 6 to move along the length direction of the drive plate 5 and a lifting mechanism 8 for driving the translation mechanism 7 to rise and fall in the vertical direction. The sandblasting pipe 41 of the sandblasting and rust removal machine 4 passes through one of the vertical seats 21 and extends to the upper part of the drive plate 5. The sandblasting nozzle 42 at the end of the sandblasting pipe 41 is fixedly mounted on the mounting seat 6.

[0032] The sandblasting machine is started, causing sandblasting particles to be ejected at high speed from the sandblasting nozzle 42. When the sandblasting particles impact the channel steel, they can remove rust from the impacted areas. The drive motor 34 drives the chain 33, which in turn drives the drive plate 5 to move along a designated trajectory. During this movement, the mounting base 6 drives the sandblasting nozzle 42 to sandblast and remove rust from the upper and lower surfaces of the channel steel. After moving a certain distance, the translation mechanism 7 moves the mounting base 6 a certain distance along the width of the channel steel. The drive mechanism 3 then moves the drive plate 5 again, allowing the mounting base 6 to drive the sandblasting nozzle 42 to continue the next distance, sandblasting and removing rust from the next position on the channel steel. The lifting mechanism 8 moves the translation mechanism 7 upwards a certain distance to facilitate rust removal from the top surfaces of both sides of the channel steel, ensuring a certain degree of uniformity in rust removal. It should be noted that in this embodiment, a certain distance refers to the drive plate 5 moving along the length of the channel steel, passing through the curved section of the chain 33, and then moving another distance along the length of the channel steel. After each segment of movement is completed, the drive motor 34 is reversed to allow for the immediate commencement of the next segment.

[0033] Reference Figure 2 , Figure 3 , Figure 4 As shown, a limiting groove 211 for moving the sandblasting pipe 41 is provided on the vertical base 21 near the sandblasting and rust removal machine 4. The shape of the limiting groove 211 is adapted to the moving trajectory of the sandblasting pipe 41. The limiting groove 211 is composed of two horizontal grooves 2111 and a semi-circular groove 2112 located between the two horizontal grooves 2111. The sandblasting pipe 41 includes a first branch pipe 411, a second branch pipe 412 and a connecting pipe 413. One end of the first branch pipe 411 is connected to the sandblasting and rust removal machine 4. The second branch pipe 412 is connected to the end of the first branch pipe 411 away from the sandblasting and rust removal machine 4. One end of the connecting pipe 413 is connected to the end of the second branch pipe 412 away from the first branch pipe 411, and the other end is connected to the sandblasting nozzle 42. Two limiting plates 4111 are fixedly installed on the first branch pipe 411. The two limiting plates 4111 are located on the inner and outer sides of the vertical seat 21, respectively, so as to limit the position of the first branch pipe 411. Multiple fixing blocks 56 are fixedly installed on the transmission plate 5. The second branch pipe 412 is fixedly inserted between the two fixing blocks 56 and fixedly connected to the fixing blocks 56, so as to ensure that when the transmission plate 5 moves, the first branch pipe 411 can be moved by the second branch pipe 412 to adapt to the change of position of the transmission plate 5. The connecting pipe 413 is a flexible pipe that can be bent to adapt to the change of position of the sandblasting nozzle 42 in the length direction of the moving seat.

[0034] Specifically, refer to Figure 4 , Figure 5 As shown, the translation mechanism 7 includes a translation seat 71, the length direction of which is consistent with the width direction of the base 1. A translation groove 711 is formed on one side of the translation seat 71 along its own length direction. A lead screw 72 is rotatably connected in the translation groove 711. A translation motor 73 for driving the lead screw 72 to rotate is provided at one end of the translation seat 71. A translation block 74 is slidably arranged in the translation groove 711. A threaded groove is formed on the translation block 74 and it is threadedly connected to the lead screw 72. A mounting seat 6 is installed on the end of the translation block 74 facing out of the translation groove 711. By driving the lead screw 72 to rotate through the translation motor 73, the translation block 74 can be moved along the length direction of the translation groove 711. This allows the sandblasting nozzle 42 to move synchronously a certain distance through the mounting seat 6. This allows the position of the sandblasting nozzle 42 in the width direction of the channel steel to be changed after the transmission mechanism 3 drives the transmission plate 5 to move a certain distance, so as to continue the sandblasting and rust removal operation for the next stroke.

[0035] Reference Figure 5As shown, the mounting base 6 is rotatably connected to the side of the translation block 74 facing the translation groove 711 via a rotating shaft 61, and the top of the mounting base 6 extends above the translation base 71. A torsion spring 62 is disposed between the mounting base 6 and the translation block 74, and the torsion spring 62 is sleeved on the outside of the rotating shaft 61. Both sides of the top of the translation base 71 are equipped with abutting members 75 that can abut against the mounting base 6. When the mounting base 6 abuts against the abutting members 75, it can rotate around the rotating shaft 61 as the rotation center. When the translation motor 73 is started, it drives the translation block 74 to move until the top of the mounting base 6 abuts against the abutting members 75. When the translation block 74 is moved further, the rotating shaft 61 can be rotated so that the sandblasting nozzle 42 rotates toward the arc-shaped chamfer inside the channel steel, thereby facilitating rust removal at the arc-shaped chamfer inside the channel steel. After the rust removal is completed at the inner arc chamfer of the channel steel, the translation block 74 is driven to move, so that the sandblasting nozzle 42 is aimed at the inner surface of the side of the channel steel for rust removal. After completing a section of rust removal, the lifting mechanism 8 drives the translation mechanism 7 to move upward as a whole, so that the next section of the side of the channel steel can be rust removed.

[0036] Reference Figure 4 , Figure 5 As shown, the lifting mechanism 8 includes a base 81, with lifting cylinders 82 fixedly installed on both sides of the base 81. The piston rod of the lifting cylinder 82 is fixedly connected to the translation seat 71. Activating the lifting cylinder 82 and moving its piston rod into the cylinder will drive the translation seat 71 to move upward. A sliding groove 53 is provided on the transmission plate 5 along the width direction of the base 1. The base 81 is slidably disposed in the sliding groove 53 along the length direction of the sliding groove 53. A sliding mechanism 54 for driving the base 81 to slide is provided on the transmission plate 5. The sliding mechanism 54 includes a sliding motor 541, which is fixedly installed on the transmission plate 5. A gear 542 is coaxially connected to the output shaft of the sliding motor 541. A rack 811 that meshes with the gear 542 is fixedly provided on the base 81 along the length direction of the sliding groove 53. Start the sliding motor 541. The output shaft of the sliding motor 541 drives the gear 542 to rotate. During the rotation of the gear 542, the base 81 can slide along the length of the slide groove 53 through the rack 811, so as to drive the base 81 to move the mounting seat 6 to the top surface of the side of the channel steel.

[0037] Reference Figure 5 , Figure 6As shown, the abutment 75 includes an abutment seat 751 and an abutment rod 752. The abutment rod 752 is rotatably mounted on the abutment seat 751. One end of the abutment rod 752 extends out of the translation seat 71 and can abut against the mounting seat 6. A compression spring 753 is connected between the other end of the abutment rod 752 and the translation seat 71. An abutment block 52 is provided on the transmission plate 5 above the abutment rod 752. When the lifting cylinder 82 moves the translation seat 71 upward to the designated position, the abutment block 52 abuts against the end of the abutment rod 752 away from the mounting seat 6, causing the compression spring 753 to compress. The end of the abutment rod 752 near the mounting seat 6 tilts upward and no longer abuts against the mounting seat 6. Under the elastic force of the torsion spring 62, the mounting seat 6 rotates back to the vertical position. When the sliding mechanism 54 moves the base 81 along the length of the slide groove 53 to the designated position, the sandblasting nozzle 42 on the mounting seat 6 can be aligned with the top surface of the side of the channel steel. It should be noted that after removing rust from the top surface of the side of the channel steel, the translation motor 73 should be started first to move the mounting seat 6 a certain distance towards the center of the translation seat 71 before the lifting cylinder 82 is started to move the translation seat 71 downward, so as to avoid the abutment rod 752 returning to its initial position first and obstructing the movement of the mounting seat 6.

[0038] After the upper and lower surfaces of the channel steel are derusted, when derusting the two outer sides of the channel steel, the channel steel is rotated 90 degrees and one outer side of the channel steel is brought into contact with the base 1. This allows the transmission mechanism 3 to drive the sandblasting nozzle 42 to move and derust the other outer side of the channel steel. The channel steel is then rotated 180 degrees and placed on the placement seat 22 with its bottom surface facing up. The sandblasting nozzle 42 is then aligned with the position where the channel steel is in contact with the placement seat 22. This allows the rust removal of the bottom surface of the channel steel in contact with the placement seat 22 to be performed after the other parts of the channel steel have been derusted.

[0039] Reference Figure 7As shown, a wiping block 9 for removing residual rust from the channel steel is detachably installed on one side of the transmission plate 5. The shape of one end of the wiping block 9 is adapted to the inner surface shape of the channel steel, and the shape of the other end of the wiping block 9 is adapted to the outer surface shape of the channel steel. Slide rails 55 are provided on both sides of the transmission plate 5 and sliding protrusions 91 are provided on both sides of the wiping block 9. The sliding protrusions 91 are slidably disposed in the slide rails 55 one-to-one. A limiting rod 551 for limiting the position of the sliding protrusions 91 is provided between the two slide rails 55. With the end of the wiping block 9 that matches the shape of the inner surface of the channel steel facing downwards, the sliding protrusion 91 is inserted into the slide rail 55 and the position of the wiping block 9 is fixed by the limiting rod 551. When the transmission plate 5 moves along the length of the channel steel at the upper part of the channel steel under the drive of the chain 33, the rust attached to the inner surface of the channel steel can be wiped. With the end of the wiping block 9 that matches the shape of the outer surface of the channel steel facing downwards and fixed in the slide rail 55, when the transmission plate 5 moves along the length of the channel steel at the lower part of the channel steel under the drive of the chain 33, the rust attached to the outer surface of the channel steel can be wiped.

[0040] The working process of this embodiment is as follows: the channel steel is placed between two placement seats 22, the sandblasting machine is started so that the sandblasting particles are sprayed out from the sandblasting nozzle 42 at high speed. The transmission motor 34 drives the chain 33 to drive the transmission plate 5 to move along the specified trajectory. During the movement, the mounting seat 6 can drive the sandblasting nozzle 42 to sandblast and remove rust from the upper and lower surfaces of the channel steel. After moving a certain distance, the translation mechanism 7 drives the mounting seat 6 to move a certain distance along the width direction of the channel steel. The transmission mechanism 3 drives the transmission plate 5 to move again so that the mounting seat 6 drives the sandblasting nozzle 42 to continue to the next distance to sandblast and remove rust from the next position of the channel steel.

[0041] The translation motor 73 is started to drive the translation block 74 to move until the top of the mounting base 6 abuts against the contact part 75, causing the rotating shaft 61 to rotate. This causes the sandblasting nozzle 42 to rotate toward the inner arc-shaped chamfer of the channel steel, so as to remove rust from the arc-shaped chamfer of the channel steel. The translation block 74 is continued to move, so that the sandblasting nozzle 42 continues to rotate and is aimed at the inner surface of the side of the channel steel to remove rust. After completing a section of rust removal, the lifting mechanism 8 drives the translation mechanism 7 to move upward as a whole, so that the next section of the side of the channel steel can be removed.

[0042] When the lifting mechanism 8 moves the translation seat 71 upward to the designated position, the abutment block 52 abuts against the end of the abutment rod 752 away from the mounting seat 6, and the end of the abutment rod 752 near the mounting seat 6 tilts upward and no longer abuts against the mounting seat 6. Under the elastic force of the torsion spring 62, the mounting seat 6 rotates back to the vertical state, and the sliding mechanism 54 is activated to drive the base 81 to slide along the length of the slide groove 53. The mounting seat 6 drives the sandblasting nozzle 42 to move towards the top surface of the side of the channel steel in order to remove rust from the top surface of the side of the channel steel.

[0043] Rotate the channel steel 90 degrees and place one of its outer sides against the base 1. This allows the transmission mechanism 3 to move the sandblasting nozzle 42 to remove rust from the other outer side of the channel steel. After removing rust from the other parts of the channel steel, rotate the channel steel 180 degrees and place it on the placement seat 22 with its bottom surface facing up. Align the sandblasting nozzle 42 with the position where the channel steel contacts the placement seat 22 to remove rust from the bottom part of the channel steel that contacts the placement seat 22.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
