[0027] Please see Figures 1-5 A coating device for repairing reinforced concrete structures includes a material conveying assembly 1, which includes a hollow cylinder 101, with a connector 103 connected to the top of the hollow cylinder 101.

[0028] Furthermore, a handrail 102 is fixedly connected to the top of the surface of the hollow cylinder 101. The connector 103 is connected to the conveying pipe for the repair material, so that when the external material pump is working, the repair material can be fed into the hollow cylinder 101 through the connector 103.

[0029] Furthermore, it also includes a rotating pressing component 2, which is installed at the bottom of the surface of the hollow cylinder 101. The rotating pressing component 2 includes a motor 210 and a positioning sleeve 202. A second bevel gear 211 is fixedly installed at the output end of the motor 210. A movable disk 208 is movably installed at the bottom of the outer ring of the positioning sleeve 202. A first bevel gear 209 is fixedly sleeved on the top of the surface of the movable disk 208. A pressing disk 207 is provided at the bottom of the movable disk 208. Magnetic components 206 are fixedly embedded on the side of the pressing disk 207 opposite to the movable disk 208.

[0030] Furthermore, the positioning sleeve 202 is fixedly fitted onto the bottom of the hollow cylinder 101.

[0031] Furthermore, an auxiliary frame 201 is fixedly connected to the left side of the hollow cylinder 101, and the motor 210 is bolted onto the auxiliary frame 201.

[0032] Furthermore, the output end of the motor 210 is movably connected to the auxiliary frame 201 via a bearing, and the controller 212 is mounted on the top screw of the auxiliary frame 201.

[0033] Furthermore, a through groove 203 is provided at the center of the surfaces of both the movable disc 208 and the pressure disc 207, and the positioning sleeve 202 is movably connected to the through groove 203 on the movable disc 208 via a bearing.

[0034] Furthermore, the first bevel gear 209 meshes with the second bevel gear 211, and separation grooves 205 are provided through the right side of both the pressure plate 207 and the movable plate 208.

[0035] Furthermore, a T-slot 204 is fixedly connected to the top of the pressure plate 207, and the top of the T-slot 204 extends through to the top of the movable plate 208 and slides in contact with the movable plate 208. After the repair material is filled, when compaction is required, the worker holds the handrail 102 and adjusts the position and height of the pressure plate 207. Then, the magnetic component 206 is energized to generate magnetic repulsion, which causes the pressure plate 207 to automatically move down and compact the repair material. Similarly, when the magnetic component 206 is energized to generate magnetic attraction, the pressure plate 207 will automatically move up. This cycle is repeated to complete multiple compaction processes, ensuring the stability of the connection between the repair material and the reinforced concrete. When leveling is required, the worker holds the handrail 102 and makes the pressure plate 207 contact the top surface of the repair. The motor 210 is controlled to drive the second bevel gear 211 to rotate. Under the meshing transmission of the first bevel gear 209, the movable plate 208 drives the pressure plate 207 to rotate together, so that the excess repair material is placed in the separation groove 205. With the rotation of the pressure plate 207 and the overall displacement of the device, the leveling of the repair position can be completed, which better meets the actual construction needs.

[0036] Furthermore, it also includes a convenient transmission component 3, which is installed at the bottom of the hollow cylinder 101. The convenient transmission component 3 includes a positioning frame 301 and a transmission head 306. The surface of the positioning frame 301 is respectively fitted with a movable block 302 and a torsion spring 303. The left and right sides of the transmission head 306 are provided with slots 305.

[0037] Furthermore, the transmission head 306 is slidably sleeved on the hollow cylinder 101 and sealed with the hollow cylinder 101, and the movable block 302 is movably connected to the positioning frame 301.

[0038] Furthermore, there are two torsion springs 303, which are located on the front and rear sides of the movable block 302 respectively. One end of the torsion spring 303 is fixedly connected to the surface of the positioning frame 301, and the other end of the torsion spring 303 is fixedly connected to the surface of the movable block 302.

[0039] Furthermore, the slot 305 is adapted to the movable block 302, and the bottom of the movable block 302 is provided with an inclined groove 304. Before the injection repair operation, according to the size of the space with the injection position, a suitable transmission head 306 is selected, and the transmission head 306 is moved upward to contact the inclined groove 304, generating a resistance force on the movable block 302. The movable block 302 naturally rotates outward around the positioning frame 301, and the torsion spring 303 is tightened. After the transmission head 306 moves upward and completes the docking with the hollow cylinder 101, the slot 305 and the movable block 302 are in an aligned state. At this time, under the reset action of the torsion spring 303, the movable block 302 can automatically enter the slot 305, completing the engagement of the transmission head 306 and ensuring the installation stability of the transmission head 306.

[0040] Specifically, the magnetic component 206 includes an electromagnet, a battery, a current commutator, and a wireless signal receiver. The battery powers the electromagnet, the wireless signal receiver receives signals from the controller 212, and the current commutator changes the direction of the current input from the battery to the electromagnet. When the magnetic poles of the electromagnets in the upper and lower magnetic components 206 are the same, a magnetic repulsion force is generated, causing the pressure plate 207 to move downward. When the magnetic poles of the electromagnets in the upper and lower magnetic components 206 are opposite, a magnetic attraction force is generated, causing the pressure plate 207 to move upward.

[0041] The controller 212 is equipped with a wireless signal transmitter for use with a wireless signal receiver on the magnetic component 206;

[0042] By setting up the hollow cylinder 101 and the connector 103, the connector 103 can be connected to the conveying pipe of the repair material, thereby continuously transmitting the repair material to the hollow cylinder 101. By setting up the handrail 102, it is convenient for the staff to hold and drive the hollow cylinder 101 to move. By setting up the auxiliary frame 201, the fixed installation requirements of the auxiliary frame 201 and the controller 212 can be met. By setting up the positioning sleeve 202, the movable installation requirements of the movable plate 208 can be met, allowing the movable plate 208 to rotate while preventing the movable plate 208 from moving up and down. By setting up the through groove 203, it can provide good space to meet the installation requirements of the positioning sleeve 202, and the internal space of the positioning sleeve 202 can also meet the rotation space requirements of the movable block 302. By setting up the T-slot 204, the pressure plate 20 can be... 7. The vertical displacement is guided to ensure the stability of the pressure plate 207. The separation groove 205 is set to facilitate the insertion of excess material, which is beneficial to the flatness of the repair surface. The first bevel gear 209 and the second bevel gear 211 are set to achieve meshing transmission. Under the drive of the motor 210, the movable plate 208 can rotate continuously. The torsion spring 303 is set to provide torque to the movable block 302, thereby preventing the movable block 302 from rotating randomly without external force. The inclined groove 304 is set to allow the movable block 302 to be pressed and automatically rotate outward when the transmission head 306 moves up and contacts the inclined groove 304. The movable block 302 and the slot 305 are set to play a clamping and positioning role in the installation state, thereby preventing the transmission head 306 from moving up and down randomly.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
