Description

Technical Field

[0001] The utility model relates to the technical field of steel bar rust removal, in particular to a construction steel bar rust removal device. Background Art

[0002] Rebar is a kind of steel commonly used in construction projects, mainly used to reinforce concrete structures and improve their bearing capacity and durability. However, during construction, some steel bars used in construction may rust in a humid environment due to long-term stacking. In order to prevent the rust on the steel bars from affecting the adhesion between the steel bars and concrete, it is necessary to use a rust removal device to remove the rust on the surface of the steel bars. Existing rust removal devices sometimes use a disc wire brush to rotate at high speed to clean the rust on the steel bars. However, the disc wire brush is usually used to remove rust on a part of the steel bar, so the steel bar needs to be rusted for multiple times, and the rust removal efficiency is relatively poor.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 5 In the embodiment of the utility model, a construction steel bar rust removal device includes a base 100, a rust removal module 200, and two conveying modules 300;

[0030] The rust removal module 200 is arranged on the top surface of the base 100, and the rust removal module 200 includes a fixed seat 210, the inner side surface of the fixed seat 210 is rotatably connected with a connecting cylinder 230, and a plurality of rust removal seats 240 are equidistantly arranged in a circular manner on the side surface of the connecting cylinder 230, and two sliding seats 241 are arranged on the inner side surface of the rust removal seat 240, and a plurality of steel wire strips are fixedly connected to the side surface of the sliding seat 241, and a plurality of abutment columns 242 are fixedly connected to the side surface of the rust removal seat 240, and the steel wire strips and the abutment columns 242 are both located inside the connecting cylinder 230, and a round ball is rotatably connected to the inner side surface of the end of the abutment column 242;

[0031] The two sliding seats 241 are located on the side outside the connecting tube 230 and are fixedly connected to the connecting rod 243. The connecting rod 243 is located outside the connecting tube 230. The side of the connecting rod 243 is rotatably connected to an adjusting screw 244 that is screwed and connected to the inner side of the rust removal seat 240. The adjusting screw 244 can limit the connecting rod 243 on the rust removal seat 240, thereby limiting the position of the sliding seat 241 relative to the rust removal seat 240. Both sides of the fixed seat 210 are fixedly connected to the top surface of the base 100. The fixedly connected side panels 220 and the fixed seat 210 are located between the two side panels 220. A shielding cloth 221 is provided on the inner side of the side panel 220. The shielding cloth 221 is annular and has an elastic rope in the middle. When the steel bar passes through the shielding cloth 221, the middle part of the shielding cloth 221 can be roughly attached to the side of the steel bar under the action of the elastic rope. In this way, during the rust removal process, the rust particles brushed off can be blocked by the shielding cloth 221. The two conveying modules 300 are fixedly connected to the base 100.

[0032] Specifically, the steel bars can be transported by two conveying modules 300, and the steel bars can be passed through the inside of the shielding cloth 221 and then through the inside of the connecting tube 230. At this time, the steel bars can be abutted by the round balls on the ends of the abutting columns 242 to limit the position of the steel bars, so that the connecting tube 230 can drive the rust removal seat 240 to rotate, and the rust removal seat 240 can drive the sliding seat 241 to rotate around the steel bars, so that the steel wire strips on the sliding seat 241 can clean and remove rust from the steel bars. By rotating the steel wire strips around the steel bars, the surface of the steel bars can be more comprehensively derusted, and the round balls can be used to limit the steel bars to avoid bending of the steel bars inside the connecting tube 230, which is beneficial to the steel bars and The steel wire maintains stable contact, which is convenient for uniform rust removal of various parts of the steel bar. The adjusting screw rod 244 can be rotated to move the connecting rod 243 relative to the rust removal seat 240, and the connecting rod 243 can drive the sliding seat 241 to move. In this way, the position of the sliding seat 241 can be adjusted according to the diameter of the steel bar to make the steel wire and the steel bar in stable contact, and the position of the steel wire can be adjusted according to the wear of the steel wire. At the same time, when the wear of the steel wire is large, the adjusting screw rod 244 can be rotated to disengage the adjusting screw rod 244 from the rust removal seat 240. At this time, the sliding seat 241 can be pulled out of the rust removal seat 240, so that a new sliding seat 241 and steel wire can be replaced as needed.

The ends of the two transmission shafts 213 are rotatably connected to the inner side surface of the fixed base 210. The inner side surfaces on both sides of the fixed base 210 are rotatably connected to a rotating shaft 214. The side surfaces of the transmission shaft 213 and the side surfaces of the rotating shaft 214 are fixedly sleeved with a transmission gear 215, and two adjacent transmission gears 215 are meshed for transmission. The side surface of the connecting tube 230 is located inside the fixed base 210 and is fixedly sleeved with a gear ring 231, and the bottom of the gear ring 231 is meshed for transmission with the adjacent transmission gear 215.

[0037] The conveying frame 310 is fixedly connected to the top surface of the base 100, and the inner side surface of one side of the conveying frame 310 is rotatably connected to a bidirectional screw rod 311. The two sliding blocks 320 are both slidably connected to the inner side surface of the conveying frame 310. The two sliding blocks 320 are both screwed together with the bidirectional screw rod 311. The inner side surface of the sliding block 320 is rotatably connected to a connecting shaft 321. The two conveying wheels 330 are respectively arranged inside the two sliding blocks 320. The inner side surface of the conveying wheel 330 is fixedly connected to the side surface of the adjacent connecting shaft 321. The conveying wheel 330 is connected to the connecting shaft 321 through the connecting shaft 321. The two-way lead screw 311 can limit the height of the two sliding blocks 320, thereby limiting the position of the conveying wheel 330. The driving box 340 is fixedly connected to one sliding block 320. The inner side of the driving box 340 is provided with a driving motor 341. The output end of the driving motor 341 is drivingly connected to a driving shaft 342 that is rotatably connected to the inner side of the driving box 340. The end of the driving shaft 342 is fixedly connected to the end of the adjacent connecting shaft 321.

[0038] During specific implementation, the bidirectional screw rod 311 can be rotated to make the two sliding blocks 320 move away from each other, and the sliding block 320 can drive the conveying wheel 330 to move through the connecting shaft 321, so that the two conveying wheels 330 move away from each other. In this way, the spacing between the two conveying wheels 330 can be adjusted according to the diameter of the steel bar, and then the steel bar can be passed through the two conveying wheels 330, and the steel bar is supported by the conveying wheels 330. At this time, the driving motor 341 can be used to drive the driving shaft 342 to rotate, and the driving shaft 342 can drive the adjacent connecting shaft 321 to rotate, so that the conveying wheel 330 at the bottom rotates to convey the steel bar.

[0039] Embodiment 2

[0040] Based on the first embodiment, Figure 3-Figure 5 As shown, in this embodiment, the side of the connecting cylinder 230 is rotatably connected to two fixing plates 250, a plurality of rust removal seats 240 are located between the two fixing plates 250, and the opposite surfaces of the two fixing plates 250 are provided with a plurality of arc grooves 251, and the two sides of the rust removal seats 240 are fixedly connected to round blocks 245 that are slidably connected to the inner sides of the adjacent arc grooves 251, and the opposite surfaces of the two fixing plates 250 are fixedly connected to the connecting frame 260;

[0041] Two positioning rings 232 are fixedly connected to the side of the connecting tube 230, and the two fixing plates 250 are located between the two positioning rings 232. A positioning box 252 is fixedly connected to the side of the fixing plate 250 corresponding to the positioning ring 232. The inner side of the positioning box 252 is slidably connected to a positioning block 253 abutting the side of the adjacent positioning ring 232. The inner side of the positioning box 252 is rotatably connected to a positioning screw rod 254 that is screwed together with the inner side of the positioning block 253. The rust removal seat 240 is slidably set on the connecting tube 230. The positioning screw rod 254 can limit the position of the positioning block 253, so that the positioning block 253 can stably abut against the positioning ring 232, thereby preventing the fixing plate 250 from rotating relative to the connecting tube 230. The fixing plate 250 can limit the position of the round block 245 through the arc groove 251, thereby limiting the position of the rust removal seat 240 relative to the connecting tube 230, so that the round ball can stably abut against the steel bar.

[0042] In a specific implementation, the positioning screw rod 254 can be rotated to move the positioning block 253 away from the positioning ring 232, so that the positioning ring 232 is separated from the positioning block 253. At this time, the fixing plate 250 can be rotated relative to the connecting tube 230. The two fixing plates 250 can be rotated synchronously through the connecting frame 260. When the fixing plate 250 rotates, the round block 245 can be pushed to move through the arc groove 251, so that the rust removal seat 240 moves relative to the connecting tube 230, so that the rust removal seat 240 moves toward the inside or outside of the connecting tube 230, and the rust removal seat 240 can drive the abutment The column 242 moves to adjust the position of the ball, so that it can adapt to the abutment and clamping of steel bars with different diameters. After the adjustment is completed, the positioning screw 254 can be rotated in the opposite direction to make the positioning block 253 abut against the positioning ring 232 again. In this way, when the connecting tube 230 rotates, the connecting tube 230 can drive the positioning block 253 to rotate through the positioning ring 232, and the positioning block 253 can drive the fixed plate 250 to rotate through the positioning box 252, thereby making the fixed plate 250 follow the rotation of the connecting tube 230, and the position of the rust removal seat 240 is always limited by the fixed plate 250.

[0043] A plurality of positioning teeth can be provided on the annular side surface of the positioning ring 232 and the side surface of the positioning block 253, so that the positioning teeth on the positioning ring 232 and the positioning block 253 can mesh with each other, so that the positioning ring 232 and the positioning block 253 can be stably abutted. When the connecting tube 230 drives the positioning ring 232 to rotate, the positioning ring 232 can drive the positioning block 253 to rotate through the positioning teeth, thereby making the fixing plate 250 stably follow the rotation of the connecting tube 230.
