Technical Field
[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device used in construction sites. Background Art
[0002] At present, many construction steel materials, such as steel pipes, are placed on construction sites. If the steel pipes are placed for a long time, the surface of the steel pipes will rust, and the rusted steel pipes will affect the use of the steel pipes, thereby reducing the bearing capacity of the steel pipes.
[0003] The commonly used rust removal methods at construction sites are: manual rust removal, mechanical rust removal and spray (blast) rust removal.
[0004] However, manual rust removal, mechanical rust removal and spray (blasting) rust removal have the following disadvantages during use:
[0005] (1) The manual rust removal method is suitable for small-scale lightweight steel pipes. The manual rust removal efficiency is low and the rust removal effect is poor.
[0006] (2) Mechanical rust removal: Use wire brushes, sandpaper, grinding wheels and other tools to polish the surface of the steel pipe to remove scale, rust and welding slag. Although mechanical rust removal is faster than manual rust removal, its efficiency is relatively low, and rust removal produces a lot of dust.
[0007] (3) Spraying (blasting) rust removal, through high-speed rotating spray (blasting) blades and abrasives (such as steel sand, steel shot, etc.) to impact the surface of the steel pipe, completely remove rust and dirt, and at the same time make the surface of the steel pipe reach a certain roughness. The spray (blasting) rust removal method is suitable for large-diameter steel pipes, which is not easy to carry out on site and requires large-scale mechanical equipment. It is only suitable for large-diameter steel pipes and has a high construction cost. Utility Model Content

[0036] The rust removal process of the rust removal device 1 provided for the construction site in this embodiment is as follows: the steel pipe to be polished passes through the clamping assembly 10 and is located at the lower part of the polishing disc 22 in the polishing machine 20, and the surface of the steel pipe to be polished contacts the polishing disc 22. The operator turns on the switch of the polishing machine 20 to energize the polishing machine 20 to work, and the polishing disc 22 rotates to remove rust from the surface of the steel pipe to be rusted. The operator pushes the polishing machine 20 to move to achieve rust removal on the surface of the steel pipe to be rusted. During the rust removal process, the first dust cover 30 and the second dust cover 40 are used to prevent impurities from flying.
[0037] Continue to participate Figure 2 and Figure 4 In this embodiment, the clamping assembly 10 includes a U-shaped frame 11 and two clamping units 12 arranged opposite to each other. The two clamping units 12 are respectively penetrated on the opposite side walls of the U-shaped frame 11. The two clamping units 12 can slide relative to the U-shaped frame 11 to adjust the distance between the two clamping units 12; by setting two clamping units 12, steel pipes to be polished with different diameters can be clamped, thereby improving the scope of application.
[0038] During use, the steel pipe to be derusted is inserted between the two clamping units 12, and the two clamping units 12 are slid to make them close to the surface of the steel pipe to be derusted.
[0039] The first dust cover 30 is adapted to the U-shaped frame 11 , and the first dust cover 30 is disposed on a portion of the U-shaped frame 11 , and an inner wall of the first dust cover 30 is adhesively connected to an outer wall of a portion of the U-shaped frame 11 .

[0041] It should be noted that the two clamping units 12 are located outside the first dust cover 30 , thereby facilitating the adjustment of the clamping units 12 .
[0042] Furthermore, in this embodiment, the clamping unit 12 includes a screw rod 121, a roller 122, a first fastening nut 123 and a second fastening nut 124. The screw rod 121 is inserted into the side wall of the U-shaped frame 11, and the screw rod 121 can slide relative to the U-shaped frame 11. One end of the screw rod 121 located inside the U-shaped frame 11 is connected to the roller 122 through a mounting frame 125, and the roller 122 can rotate relative to the mounting frame 125. The first fastening nut 123 is sleeved on one end of the screw rod 121 away from the roller 122, and the second fastening nut 124 is sleeved on the screw rod 1 21, the second fastening nut 124 is located between the side wall of the U-shaped frame 11 and the mounting frame 125; when the screw rod 121 slides to the preset position, the first fastening nut 123 is screwed so that the first fastening nut 123 faces one side of the U-shaped frame 11 and abuts against the outer side of the side wall of the U-shaped frame 11, and the second fastening nut 124 is screwed so that the second fastening nut 124 faces away from the mounting frame 125 and abuts against the inner side of the side wall of the U-shaped frame 11; by setting the first fastening nut 123 and the second fastening nut 124, the screw rod 121 is prevented from sliding.

In an implementation in which the mounting frame 125 is U-shaped, one end of the screw rod 121 passes through the side wall of the U-shaped frame 11 and is connected to the closed end of the mounting frame 125, and the roller 122 is partially inserted into the mounting frame 125. The roller 122 is connected to the mounting frame 125 via a rotating shaft, and the roller 122 can rotate relative to the mounting frame 125.
[0045] The grinding sheet 22 in the grinding machine 20 is located in the middle between the two rollers 122 , and the grinding sheet 22 is located at the upper end of the rollers 122 , that is, the grinding sheet 22 is higher than the rollers 122 .
[0046] Furthermore, in the present embodiment, through holes 111 are provided on the opposite side walls of the U-shaped frame 11, and the two through holes 111 are arranged opposite to each other. The through holes 111 and the screw rods 121 are arranged one by one, and the two screw rods 121 are respectively inserted into the two through holes 111, and the screw rods 121 can slide along the extension direction of the through holes 111; at least one limit block 112 is provided in each through hole 111, and at least one limit groove 1211 matched with the limit block 112 is provided on the outer peripheral wall of each screw rod 121, and the limit groove 1211 extends along the center line direction of the screw rod 121, and the limit block 112 and the limit groove 1211 are arranged correspondingly, and the limit block 112 is inserted into the limit groove 1211, and the limit block 112 can slide along the limit groove 1211; by setting the limit block 112 and the limit groove 1211, the rotation of the screw rod 121 is prevented.
[0047] Specifically, the center lines of the two through holes 111 are arranged parallel to the length direction of the first dust cover 30 . In some practicable embodiments, the center lines of the two through holes 111 are arranged collinearly. The two through holes 111 are communicated with the interior of the U-shaped frame 11 .
[0048] In this embodiment, two limit blocks 112 are disposed in each through hole 111 , and the two limit blocks 112 are spaced apart along the circumference of the through hole 111 .
[0049] It should be noted that the number of the limiting blocks 112 in the through hole 111 is substantially the same as the number of the upper limiting grooves 1211 on the screw rod 121 .
[0050] In an achievable method in which two limit blocks 112 are provided in the through hole 111, two limit grooves 1211 are provided on the outer peripheral wall of each screw rod 121, and the two limit grooves 1211 both extend along the center line direction of the screw rod 121 and pass through the end of the screw rod 121, and the two limit grooves 1211 are arranged at intervals along the circumference of the screw rod 121, and the limit grooves 1211 and the limit blocks 112 are arranged in a one-to-one correspondence; during use, the screw rod 121 is penetrated into the through hole 111, and the screw rod 121 can slide along the through hole 111, and the two limit blocks 112 in the through hole 111 are respectively inserted into the two limit grooves 1211 on the screw rod 121, and the limit blocks 112 can slide along the limit grooves 1211.
[0051] The adjustment process of the clamping unit 12 is: push the screw 121 to make the screw 121 slide along the through hole 111. At this time, the limit groove 1211 slides on the surface of the limit block 112. The limit block 112 limits the screw 121 through the limit groove 1211 to prevent it from rotating, thereby improving the smoothness of the rolling of the roller 122. When the screw 121 slides to the specified position, at this time, the roller 122 fits the surface of the steel pipe to be derusted, and then rotates the first fastening nut 123 and the second fastening nut 124 to make the first fastening nut 123 and the second fastening nut 124 respectively abut against the opposite sides of the side wall of the U-shaped frame 11 to fix the screw 121.
[0052] For example, the roller 122 can be made of nylon. Of course, the roller 122 can also be made of rubber. In the implementation method where the roller 122 is made of nylon, nylon has wear resistance, thereby increasing the service life of the roller 122.
[0053] Continue to refer to Figure 1 The rust removal device 1 for construction sites provided in this embodiment also includes an operating unit 50, and the grinder 20 is partially inserted into the operating unit 50, and the opposite sides of the operating unit 50 are respectively connected to the two sides of the housing 21 of the grinder 20; by setting the operating unit 50, the operating unit 50 is used to push the rust removal device 1 to move, thereby improving convenience.

[0055] Specifically, the U-shaped connecting frame 51 is connected to the side wall of the housing 21 of the grinder 20 by bolt connection.
[0056] Furthermore, in this embodiment, a preset angle is provided between the extension direction of the handle 52 and the movement direction of the grinder 20 .
[0057] The preset angle ranges from 45° to 60°. The extension direction of the U-shaped connecting frame 51 is parallel to the center line of the handle 52 .
[0058] In order to improve the comfort of the grip 52 , a rubber sleeve is provided on the grip 52 .
[0059] Exemplarily, both the first dust cover 30 and the second dust cover 40 can be made of rubber material; of course, both the first dust cover 30 and the second dust cover 40 can also be made of plastic material. In the implementation mode where both the first dust cover 30 and the second dust cover 40 are made of rubber material, two cutouts 31 are provided on the side of the first dust cover 30 away from the second dust cover 40, and the two cutouts 31 are arranged at intervals along the length direction of the first dust cover 30; by providing the cutouts 31, the fit between the first dust cover 30 and the surface of the steel pipe to be derusted is improved, and the dustproof effect is further increased.

Then, the operator holds the screw 121 by hand and pushes it hard, and the screw 121 slides along the through hole 111. The sliding of the screw 121 drives the roller 122 to move until the two rollers 122 are in contact with the surface of the steel pipe to be polished, and stops pushing the screw 121. Then, the operator rotates the first fastening nut 121 with a wrench. 3 and the second fastening nut 124, so that the first fastening nut 123 and the second fastening nut 124 are both in contact with the surface of the side wall of the U-shaped frame 11 to fix the screw 121; then, the operator turns on the switch on the grinder 20 to power on the grinder 20, and the grinding sheet 22 rotates to remove rust on the surface of the steel pipe to be grinded. The operator can push the grinder 20 to move through the grip 52. When the grinder 20 moves, the two rollers 122 roll on the surface of the steel pipe to be grinded, thereby achieving a guiding effect.
