Position.

[0027] The embodiment of the present application enables the staff to pick up the steel bar rust removal device by holding the handheld part. When the rusted part of the steel bar 4 needs to be treated, after taking the handheld part to move the rotating steel brush 3 to the corresponding position, the position does not need to be adjusted before the rust treatment at the location is completed, so that the process of using the steel bar rust removal device to remove rust on the steel bar 4 is easier to control, and during the rust removal process, the driving member drives the transmission device to move, and then drives the rotating steel brush 3 to rotate, so that the rotating steel brush 3 can perform rust removal operations on the steel bar 4. The rotation of the rotating steel brush 3 under the action of the transmission device can save human resources in the rust removal process, and although the rotating steel brush 3 has a certain amount of loss, it can still be reused many times, and its cost is low. When the rust removal effect of the rotating steel brush 3 is not good, a new steel brush can be replaced, and the use of the rotating steel brush 3 to treat the rust on the surface of the steel bar 4 has less damage to the strength of the steel bar 4 itself, which solves the technical problems of using rust removers to treat the steel bar 4 in the related art, increasing construction costs, and affecting the strength of the steel itself.

[0028] In some optional embodiments, the hand-held portion includes a first handle 11 and a second handle 12 hinged to the first handle 11, and preferably, the ends of the first handle 11 and the ends of the second handle 12 are hinged; the connecting component includes a first rod, and the first rod is fixed to the first handle 11; the connecting component also includes a second rod, and the second rod is fixed to the second handle 12. The first handle 11, the second handle 12, the first rod and the second rod together form a scissor-like structure, and the first rod and the second rod are both detachably connected to the rotating steel brush 3. When the first handle 11 and When the second handle 12 moves in a direction approaching each other, the first rod and the second rod move in a direction approaching each other; when the first handle 11 and the second handle 12 move in a direction away from each other, the first rod and the second rod move in a direction away from each other. At this time, the first rod and the second rod can be moved in a direction approaching or away from each other by controlling the first handle 11 and the second handle 12. When it is necessary to remove rust from the steel bar 4, the first rod and the second rod are placed on opposite sides of the steel bar 4 and the rotating steel brush 3 is applied to the steel bar 4, and then the driving member is started to perform the brushing operation.

[0029] In some optional embodiments, the transmission device includes: a first transmission member, the first transmission member is installed on the first rod; a second transmission member, the second transmission member is installed on the second rod, the first transmission member and the second transmission member are both connected to the driving member, and the driving member synchronously drives the first transmission member and the second transmission member to rotate, so that the rotating steel brush 3 connected to the first rod and the second rod synchronously rotates around its own axis. In the embodiment of the present application, the first transmission member and the second transmission member are synchronously driven by the driven member, which can effectively save resources and make it easier to control the steel bar rust removal device. In some other embodiments, the first transmission member and the second transmission member can also be controlled separately by one or more driving members.

[0030] In some optional embodiments, the connecting assembly is equipped with a rotating shaft that cooperates with the transmission device. It should be understood that the transmission device can drive the rotating shaft to rotate around the axis of the rotating shaft; the rotating steel brush 3 is fixed with a fixed groove, the fixed groove is coaxially arranged with the rotating steel brush 3, and the rotating shaft is installed in the fixed groove. In the embodiment of the present application, the rotating shaft is also installed in the first rod and the second rod. At this time, the rotating steel brush 3 is detachably connected to the connecting assembly by inserting the rotating shaft into the fixed groove. When the rotating steel brush 3 needs to be replaced, the staff can forcefully pull the rotating shaft out of the fixed groove shaft to separate the old rotating steel brush 3 from the first rod or the second rod. In some other embodiments, the rotating steel brush 3 can also be detachably connected to the connecting assembly by setting a rotating groove in the first rod and the second rod, and the rotating steel brush 3 has a fixed shaft, and the fixed shaft can be inserted into the rotating groove.

[0031] Preferably, the first rod and the second rod are both connected to two of the rotating steel brushes 3, and the four rotating steel brushes 3 together form a steel bar placement cavity. The four rotating steel brushes 3 can be together arranged around the steel bar 4. When the steel bar 4 is placed in the steel bar placement cavity, the surrounding side of the steel bar 4 can be surrounded by the four rotating steel brushes 3, so that the steel bar rust removal device can achieve a wider range of rust removal effects through one operation, and can speed up the rust removal efficiency.

[0032] In some optional embodiments, the first rod member includes a first short rod 21 and a first straight rod 22 connected to the first short rod 21, and the first short rod 21 is connected to the first handle 11; the second rod member includes a second short rod 23 and a second straight rod 24 connected to the second short rod 23, and the second short rod 23 is connected to the second handle 12; the first short rod 21 and the second short rod 23 are at an angle to each other, the first straight rod 22 is parallel to the second straight rod 24, and the four rotating steel brushes 3 are respectively connected to the first short rod 21 and the second short rod 23, see Figure 1 As shown, the first straight rod 22 and the second straight rod 24 are parallel to each other, which can make the four rotating steel brushes 3 fit more closely with the steel bars 4. In addition, when the diameters of all the rotating steel brushes 3 are the same, this arrangement can also make the force exerted by the four rotating steel brushes 3 on the steel bars 4 more uniform.

[0033] In some optional embodiments, the driving member is installed on a side of the connecting assembly close to the handheld portion. Installing the driving member there can minimize the impact of the driving member on the work process of the staff, and is not only away from the handheld portion held by the staff, but also as far away as possible from the rotating steel brush 3 that needs to be rusted. The driving member is connected to the transmission device by signal. It should be understood that the signal connection can also be an electrical signal. In the embodiment of the present application, the driving member can be a motor, which drives the transmission device to move while the motor rotates. The transmission device is a conveyor belt at this time. The conveyor belt drives the rotating steel brush 3 to rotate while being transported and moved by the motor. In some other embodiments, the driving member can also be other structures with driving performance.

[0034] In some optional embodiments, the rust removal mechanism further includes a battery assembly, which can be installed in a battery box. The battery box is preferably also arranged on the side of the connecting assembly close to the handheld portion. It is necessary to ensure that the battery box and the driving member are arranged at a distance and do not affect each other. The battery assembly is electrically connected to the driving member. Preferably, the battery assembly installed in the battery box has a power storage function, the battery assembly is used for power supply, and the battery assembly can be charged or directly replaced.

[0035] Preferably, the thickness of the rotating steel brush 3 along its axial direction is 5 to 10 cm. The rotating steel brush 3 having a certain thickness can increase the rust removal range of the rotating steel brush 3 on the steel bar 4. Setting the thickness to 5 to 10 cm can make the various parts of the rotating steel brush 3 more thoroughly remove the rust on the steel bar 4. If the length of the rotating steel brush 3 along its axial direction is too long, when the rotating steel brush 3 is removing rust from the steel bar 4, the side away from the connecting component along the axial direction may not fit well with the outer periphery of the steel bar 4, thereby reducing the rust removal effect of the steel bar rust removal device on the steel bar 4.

[0036] Preferably, the hand-held portion is provided with an anti-slip cover. When the staff holds the hand-held portion, the hand directly holds the anti-slip cover so that the steel bar rust removal device can be held as tightly as possible during the rust removal process, thereby reducing the risk of falling.
