Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to an anti-corrosion treatment device for embedded parts. Background Art

[0002] In the field of large-scale infrastructure construction such as bridges, embedded parts play a crucial role. They are pre-buried in concrete structures for subsequent connection and fixation of various accessory components. However, during the transportation process of embedded parts, due to the complex construction site environment and handling operations, etc., they are extremely prone to being knocked, resulting in damage to the original external protective coating. Once the protective coating is damaged, the embedded parts will be directly exposed to the external environment and are easily eroded by factors such as air and moisture, thereby leading to surface rust and corrosion. This rust and corrosion not only affect the structural strength and service life of the embedded parts themselves, but also may pose a potential threat to the stability and safety of the entire bridge structure. Therefore, it is particularly important to carry out timely and effective anti-corrosion treatment on the rusted and corroded embedded parts.

[0003] Currently, for the anti-corrosion spraying treatment equipment of embedded parts, the method of manual hand-held spray guns for spraying operations is mostly adopted, but this conventional practice has many inconveniences and problems: Firstly, the stability of the spraying equipment is poor. Because the ground conditions at the construction site are complex and diverse, during the spraying operation, the traditional simple spraying equipment lacks effective fixing devices and is prone to displacement when the spraying machine vibrates during operation; Secondly, the spraying range is limited. The structural shapes of embedded parts are various. For some embedded parts with narrow internal spaces or greater depths, the length of conventional nozzles is often insufficient for spraying the internal surfaces, making it difficult to completely cover all parts of the embedded parts with the coating, thus unable to ensure comprehensive anti-corrosion protection; Thirdly, there is a problem of insufficient lighting. In some areas with poor lighting conditions, such as underground construction parts or night operations, there is a lack of sufficient lighting to assist the operator in observing the spraying situation on the surface of the embedded parts. Summary of the Invention

[0004] In view of this, the present invention provides an anti-corrosion treatment device for embedded parts to solve the problems of poor stability of the spraying equipment, limited spraying range, difficulty in completely covering all parts of the embedded parts with the coating, and lack of sufficient lighting to assist the operator in observing the spraying situation on the surface of the embedded parts in some areas with poor lighting conditions.

[0007] Further, the fixing component also includes: A fixing cone, the fixing cone is fixedly installed at the middle position of the lower end face of the backing plate, and the fixing nail passes through the through hole on the surface of the backing plate and is wedged into the ground.

[0008] Further, the spraying pipe at the front end of the spraying machine body is wound around the outside of the rotating shaft, and the rotating shaft and the outlet end of the spraying pipe are on the same horizontal line.

[0009] Further, the first connecting pipe at the rear end of the extension pipe is externally provided with a thread, and the first connecting pipe at the rear end of the extension pipe is threadedly connected to the front end of the spray gun.

[0010] Further, a thread is opened in the groove at the front position of the inner end face of the extension pipe, and the second connecting pipe at the rear end of the spray head is threadedly connected to the groove at the front end of the extension pipe.

[0011] Furthermore, a magnet is installed on the inner end face of the sleeve. The magnet is in an annular structure, and the inner end face of the magnet is in contact with the outer end face of the extension pipe.

[0012] Furthermore, six lighting lamps are installed on the front end surface of the placement plate, and the six lighting lamps are arranged in an annular structure.

[0013] The present invention provides an anti-corrosion treatment device for embedded parts, and its beneficial effects are as follows: 1. It has a stable fixing method. The connection groove at the lower end face of the support leg cooperates with the fixing component. The backing plate is threadedly connected to the connection groove through the connection screw. The fixing cone at the lower end of the backing plate can be inserted into the ground for preliminary positioning, and then the fixing nail is driven into the ground through the through hole of the backing plate, which can firmly fix the device on the ground.

[0015] 3. The lighting lamps can provide lighting for the spraying workers. The outer end face of the sleeve installed outside the extension pipe is provided with a placement plate, and six lighting lamps arranged in an annular structure are installed on the front end surface of the placement plate. In an environment with insufficient light, turning on the lighting lamps can provide sufficient lighting for the spraying operation, and no matter how the workers operate, the irradiation direction of the lighting lamps is always the same as the direction of the spray head, enabling the operator to more clearly observe the spraying situation on the surface of the embedded part, timely discover problems such as uneven spraying and missed spraying, thereby ensuring the spraying quality and reducing the spraying defects caused by insufficient lighting.

[0016] 4. In terms of component connection and maintenance, most of the components of the device are connected by threaded connection methods, such as the spray gun and the extension pipe, the extension pipe and the spray head, the backing plate and the support leg, etc. This connection method not only facilitates the assembly and disassembly of components, but also after the spraying work is completed, it is convenient to screw the spray head off the extension pipe and the extension pipe off the spray gun to clean and maintain each component, extending the service life of the device and reducing the maintenance cost of the device. At the same time, the magnet on the inner end face of the sleeve is in contact with the iron extension pipe, and the sleeve is fixed outside the extension pipe through the attraction force, preventing the displacement of the sleeve during the spraying process and ensuring the stability of the lighting system.

Casing 9, the casing 9 is sleeved outside the extension pipe 7, the inner end face of the casing 9 is attached to the outside of the extension pipe 7, and a circular ring-shaped placement plate 901 is fixedly installed on the outer end face of the casing 9.

[0023] Among them, the fixing component includes: a backing plate 2, two through holes 202 are provided on the surface of the backing plate 2, a connecting screw 203 is fixedly installed at the middle position of the upper end face of the backing plate 2, and the connecting screw 203 is threadedly connected in the connecting groove 1021 on the lower end surface of the support leg 102; a fixing cone 201, the fixing cone 201 is fixedly installed at the middle position of the lower end face of the backing plate 2, and the fixing nail passes through the through hole 202 on the surface of the backing plate 2 and is wedged into the ground.

[0024] By adopting the above scheme, the technical effect brought is that the worker can threadedly connect the connecting screw 203 on the upper end face of the backing plate 2 into the connecting groove 1021, install the backing plate 2 under the support leg 102. The fixing cone 201 at the middle position of the lower end face of the backing plate 2 can be inserted into the ground to play a preliminary positioning role. Then, the fixing nail is passed through the through hole 202 on the surface of the backing plate 2 and wedged into the ground to further firmly fix the equipment on the ground and prevent the equipment from moving during the spraying process. Among them, the spraying pipe 501 at the front end of the spraying machine body 5 is wound around the outside of the rotating shaft 4. The rotating shaft 4 and the outlet end of the spraying pipe 501 are on the same horizontal line. During use, the rotating shaft 4 and the outlet end of the spraying pipe 501 are on the same horizontal line. Such a design facilitates the storage and deployment of the spraying pipe 501 during use and ensures the smooth use of the spraying pipe 501.

[0025] Among them, the outer surface of the first connecting pipe 702 at the rear end of the extension pipe 7 is provided with threads.

Embodiment 2: The present invention provides an anti-corrosion treatment device for embedded parts. On the basis of Embodiment 1, as Figures 1 - 8 shown, it further includes: a magnet 902 is installed on the inner end face of the sleeve 9. The magnet 902 is in a circular ring structure, and the inner end face of the magnet 902 is attached to the outer end face of the extension pipe 7. Six lighting lamps 9011 are installed on the front surface of the placement plate 901, and the six lighting lamps 9011 are arranged in a circular ring structure.

[0027] By adopting the above scheme, the technical effect brought is that a sleeve 9 is further installed outside the extension pipe 7. A placement plate 901 is installed on the outer end face of the sleeve 9. Six lighting lamps 9011 arranged in a circular ring structure are installed on the front surface of the placement plate 901. In an environment with insufficient light, the lighting lamps 9011 can be turned on to provide sufficient lighting for the spraying operation, enabling the operator to more clearly observe the spraying situation on the surface of the embedded part and ensuring the spraying quality.

[0028] Specific usage method and function of this embodiment: In the present invention, when the bridge embedded parts are being transported, they are prone to being bumped, causing the protective coating on the outside of the embedded parts to be damaged, which will lead to the phenomenon of rust and corrosion on the surface of the embedded parts. At this time, it is necessary to re-spray the surface of the embedded parts. At this time, the operator can lift the two support legs 102 at the rear end of the transport vehicle 1, and then push the device to move through the U-shaped handle on the front end face of the transport vehicle 1 in an inclined shape, which is convenient for the transport vehicle 1 to walk on the construction site. When the device reaches the designated position, it needs to be fixed to ensure the stability of the operation process. After the worker releases the handle on the upper end of the transport vehicle 1, the support legs 102 contact the ground, which can improve the stability of the transport vehicle 1. At the same time, in some bridge construction sites, the geology is relatively soft, and the spraying machine body 5 will generate vibration during operation, causing the transport vehicle 1 to displace. Through the setting of the connection groove 1021 on the lower end face of the support leg 102, the worker can thread the connection screw 203 on the upper end face of the backing plate 2 into the connection groove 1021 and install the backing plate 2 under the support leg 102. The fixing cone 201 at the middle position of the lower end face of the backing plate 2 can be inserted into the ground to play a preliminary positioning role, and then the fixing nails are passed through the through holes 202 on the surface of the backing plate 2 and wedged into the ground to further firmly fix the device on the ground and prevent the device from moving during the spraying process. The spraying machine body 5 is fixedly installed on the upper end face of the transport vehicle 1. The spraying pipe 501 at its front end is wound around the outside of the rotating shaft 4, and the rotating shaft 4 and the outlet end of the spraying pipe 501 are on the same horizontal line. Such a design is convenient for the storage and deployment of the spraying pipe 501 during use, and at the same time ensures the smooth use of the spraying pipe 501. The lower end of the spray gun 6 is fixedly connected to the spraying pipe 501. The external thread is provided on the outside of the first connecting pipe 702 at the rear end of the extension pipe 7, and it is threadedly connected to the front end of the spray gun 6. The second connecting pipe 801 at the rear end of the nozzle 8 is threadedly connected to the groove 701 at the front end of the extension pipe 7. In this way, during the actual operation process, when the worker sprays the inner surface of the embedded parts, the first connecting pipe 702 at the rear end of the extension pipe 7 can be threadedly connected to the groove 701 at the front end of another extension pipe 7, so that two or more extension pipes 7 can be butted together, and then connected to the spray gun 6 and the nozzle 8 respectively, which can bring convenience to the operation of the worker. After completing the preliminary preparation work, start the spraying machine body 5. The anti-corrosion coating is transported to the spray gun 6 through the spraying pipe 501, and then evenly sprayed on the surface of the embedded parts through the extension pipe 7 and the nozzle 8. In order to better observe the spraying effect, a sleeve 9 is also installed on the outside of the extension pipe 7. A placement plate 901 is installed on the outer end face of the sleeve 9. Six annularly arranged lighting lamps 9011 are installed on the front surface of the placement plate 901. In an environment with insufficient light, the lighting lamps 9011 can be turned on to provide sufficient lighting for the spraying operation, enabling the operator to more clearly observe the spraying situation on the surface of the embedded parts and ensuring the spraying quality. The extension pipe 7 is made of iron material, and a magnet 902 is installed on the inner end face of the sleeve 9.The magnet 902 is attached to the extension tube 7. Through the attraction between the magnet 902 and the extension tube 7, the sleeve 9 can be fixed outside the extension tube 7 to prevent the sleeve 9 from shifting during the spraying process. After the spraying work is completed, turn off the spraying machine body 5, unscrew the nozzle 8 from the extension tube 7, and unscrew the extension tube 7 from the spray gun 6, which facilitates the cleaning and maintenance of each component. Wind the spraying tube 501 around the rotating shaft 4 again for convenient use next time. Finally, pull out the fixing nail, unscrew the backing plate 2 from the support leg 102, and move the transport cart 1 to the designated storage location through the U-shaped handle.
