The grinding columns 102 are spaced apart from each other.

[0037] Specifically, the motor 103 is a multi-axis motor, and a plurality of grinding columns 102 are installed on the support seat 101 in parallel and with a gap therebetween. In order to prevent the grinding columns 102 from wearing the support seat 101, the grinding columns 102 are not in contact with the support seat 101.

[0039] In the actual rust removal process, the support seat 101 is driven by the support assembly 200 to reach the specified position. The steel bar is placed above the grinding column 102, and the contact angle between the grinding column 102 and the steel bar is adjusted by the support assembly 200. In this embodiment, the grinding column 102 is perpendicular to the steel bar. Through the relative movement of the grinding column 102 and the steel bar, the grinding and rust removal process of multiple steel bars is realized at the same time.

[0040] In an optional embodiment of the present invention, the polishing column 102 includes a column body and a polishing layer coated outside the column body, and the polishing layer is replaceably installed outside the column body, so as to extend the service life of the polishing column 102.

[0041] The steel bar rust removal device provided by the present invention can adjust the contact angle between the grinding column and the steel bar through the rotatably connected grinding assembly and the supporting assembly, thereby realizing the grinding of the steel bar without viewing angle, and can realize the simultaneous grinding of multiple steel bars by connecting multiple grinding columns distributed at intervals through an electric motor, thereby improving the grinding efficiency and ensuring the grinding quality.

[0042] Continue to refer Figure 1 In one embodiment of the present invention, the support assembly 200 includes an electric shaft 201 and a support frame 202 , and the support seat 101 is rotatably connected to the support frame 202 via the electric shaft 201 .

[0043] In other words, the electric shaft 201 can change the angle between the support base 101 and the support frame 202 .

[0044] like Figure 2 As shown, in an optional embodiment of the present invention, the steel bar rust removal device further includes a cleaning assembly 300 , and the cleaning assembly 300 is installed at one end of the support seat 101 away from the support assembly 200 .

[0045] In addition, the cleaning assembly 300 includes a rust remover, which is used to be sprayed on the steel bars.

[0046] In one embodiment of the present invention, the cleaning assembly 300 includes a box 301 with a spray port 303 and a pump 302 . The rust remover is placed in the box 301 , and the pump 302 controls the rust remover to spray out from the spray port 303 .

[0047] For easy installation, a bottom plate 110 may be provided at the lower portion of the support seat 101 , the box body 301 of the cleaning assembly 300 may be mounted on the bottom plate 110 , and the support frame 202 of the support assembly 200 may also be mounted on the bottom plate 110 .

[0048] Furthermore, a water inlet 306 is provided on the box body 301, and the water inlet 306 is provided with a sealing device.

[0049] In an optional embodiment of the present invention, the cleaning component 300 further includes a signal transceiver 304 , which is connected to the pump 302 to control the spraying of the rust remover by the pump 302 .

[0050] In other words, the pump 302 is electrically connected to the signal transceiver 304 , and the signal transceiver 304 receives a signal from the controller to control the pump 302 .

[0051] In the actual rust removal process, according to the degree of rust on the steel bar, the controller sends a signal to the signal receiver 304, thereby controlling the opening and closing of the pump 302 and adjusting the spraying amount of the rust remover to achieve a better rust removal effect.

[0052] First, spray the rust remover on the steel bar, and then pickle the steel bar with the rust remover. Then, grind and remove rust on the steel bar with the grinding column 102, which has a better effect.

[0053] In this embodiment, the rust remover is an acidic liquid, such as hydrochloric acid, and is appropriately selected according to actual conditions.

[0054] Furthermore, in a specific embodiment of the present invention, the cleaning assembly 300 further includes a guide plate 305 , and the guide plate 305 is rotatably connected in the direction of the spray port 303 .

[0055] Specifically, the guide plate 305 is connected to the bottom plate 110 via a rotating shaft, and the spraying direction of the rust remover can be changed by adjusting the angle between the guide plate 305 and the spray port 303. In addition, the guide plate 305 is made of anti-corrosion material and can be adjusted manually.

[0056] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, the steel bar rust removal device further includes a set of rotatably connected grinding components 100 and support components 200, and two support frames 202 are rotatably connected.

[0057] In other words, the steel bar rust removal device includes a first grinding assembly, a first supporting assembly, a second grinding assembly and a second supporting assembly. The first grinding assembly has the same structure as the second grinding assembly, and the first supporting assembly has the same structure as the second supporting assembly.

[0058] One end of the first supporting assembly is connected to the first grinding assembly, and the other end is connected to one end of the second supporting assembly, and the other end of the second supporting assembly is connected to the second grinding assembly.

[0059] In addition, one side of the first polishing assembly is also connected to a first cleaning assembly, and one side of the second polishing assembly is also connected to a second cleaning assembly, and the first cleaning assembly and the second cleaning assembly have the same structure.

[0060] In other words, the first grinding assembly, the first supporting assembly and the first cleaning assembly are mirror-symmetrical to the second grinding assembly, the second supporting assembly and the second cleaning assembly.

[0061] In another embodiment of the present invention, the steel bar rust removal device having two mirror-symmetrical groups of grinding components, support components and cleaning components further includes a motor 120, the shaft of which passes through one of the support frames 202 and is rotatably connected to the other support frame 202.

[0062] In other words, the shaft of the motor 120 passes through the support frame of the first support assembly and is keyed to the support frame of the second support assembly, thereby achieving angular rotation of the first support assembly and the second support assembly.

[0063] The first supporting assembly and the second supporting assembly are arranged in a herringbone shape, so that the user can control the use angle of the entire device and ensure that the grinding column can completely contact the surface of the steel bar.

[0064] Of course, in order to achieve a better rotation effect, the support frame of the first support assembly and the support frame of the second support assembly can be connected by a rotating shaft, and then the motor 120 is connected to one of the support frames to achieve rotation.

[0065] In one embodiment of the present invention, the steel bar rust removal device further includes a shock absorber 130 , and the shock absorber 130 is disposed on a support frame 202 on which the motor 120 is installed.

[0066] Through the effect of the shock absorber, the vibration generated by the entire steel bar rust removal device during operation can be greatly reduced, ensuring that the steel bar rust removal device can be stable during operation.

[0067] A light ring is provided on the signal transceiver 304 of the cleaning component 300. Through the prompting function of the light ring, it is ensured that the staff can clearly find the location of the equipment at night.

[0068] In the actual working process, the use of steel bar rust removal device:

[0069] Step 1: Lay the steel bars that need to be derusted flat;

[0070] Step 2: Place the laid steel bars on the surface of the polished column;

[0071] Step 3: Start the electric universal wheel to control the direction of the device;

[0072] Step 4: Start the pump and spray the acid solution evenly on the surface of the steel bars;

[0073] Step 5: Start the grinding column to grind the steel bars;

[0074] Step 6: Start the motor and the electric shaft, and adjust the grinding angle of the grinding column;

[0075] Step 7: After grinding, stop the grinding column and pump, put away the device and steel bars, and wipe the surface of the steel bars.

[0076] In this embodiment, a plurality of steel bars are neatly arranged to ensure that the grinding column 102 can contact the surface of all the steel bars, and the motor 103 is started so that the motor 103 drives the plurality of grinding columns 102 to rotate simultaneously. In this way, the entire grinding column 102 can remove rust from the surface of the steel bar, and the rust on the surface can be removed by rapid rotation, thereby ensuring the service life of the entire steel bar.

[0077] The support frames of the first support assembly and the second support assembly are arranged in a herringbone shape, so that the user can control the use angle of the entire device and ensure that the grinding column 102 can completely contact the surface of the steel bar.

[0078] The motor 120 drives the shaft to rotate, thereby controlling the angle between the first support assembly and the second support assembly. The shock absorber 130 can greatly reduce the vibration of the entire device during operation, thereby ensuring that the device is stable during operation.

[0079] The staff sends instructions to the signal transceiver 304 through an external controller, thereby controlling the opening and closing of the pump 302 through the signal transceiver 304, ensuring that the pump 302 can be opened and closed as needed, and then the pump 302 sprays the acidic liquid inside the box 301 through the injection port 303, evenly spraying it on the surface of the steel bar to dissolve the rust. The acidic liquid can be selected according to the actual situation, such as hydrochloric acid.

[0080] Then, the surface of the steel bar is polished and rust-removed by the polishing column 102, so that the rust removal work on the surface of the steel bar can be completed. Through the action of the motor 103, the rotation speed and rotation direction of several polishing columns 102 can be freely controlled to ensure that different rust thicknesses can be polished during the rust removal process.

[0081] The direction and area of ​​the acid solution sprayed from the spray port 303 are controlled by the guide plate 305. The rotation direction of the guide plate 305 can be controlled by the action of the movable shaft to ensure that the surface of each steel bar is covered with the acid solution, which is convenient for the normal operation of the grinding work.

[0082] The light ring ensures that the entire device can be clearly located by the staff at night. The water injection port 306 facilitates the injection of acidic solution into the box 301 .

[0083] Through the action of the electric shaft 201 and the support frame 202 , the angle between the support frame 202 and the support base 101 can be changed.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
