DETAILED DESCRIPTION
[0032] The technical solutions of the present application will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0033] The automatic pile head rust removal and paint spraying device provided in the embodiments of the present application will be described below in conjunction with Figures 1-4
[0034] Reference is made to Figure 1 As shown, the automatic pile head rust removal and paint spraying device provided in the embodiments of the present application comprises a moving mechanism, a paint supply assembly, a support frame 300, a laser assembly and a paint spraying assembly. The moving mechanism comprises a vehicle frame 110, traveling wheels 120 and a caterpillar track 130, and the caterpillar track 130 is sleeved on the traveling wheels 120. A lifting arm 200 is installed on the vehicle frame 110, and the lifting ratio can be achieved by hydraulic driving. A cab is arranged on the vehicle frame 110, and a worker can operate the driving direction of the vehicle frame 110 and the lifting of the lifting arm 200 in the cab. The paint supply assembly is arranged inside the vehicle frame 110. The support frame 300 is arranged at the upper end of the lifting arm 200, the laser assembly is arranged on the support frame 300 and used for laser rust removal of the pile head, and the paint spraying assembly is arranged on the support frame 300 and communicates with the paint supply assembly and is used for paint spraying on the surface of the pile head.
[0035] By using the technical scheme provided in the above embodiments, the lifting arm 200 is arranged to replace the worker to climb the ladder, so that the working process is safer. By arranging the laser assembly and the paint spraying assembly on the support arm, laser rust removal and paint spraying can be simultaneously achieved, so that the rust removal and paint spraying efficiency of the pile head is improved. By arranging the caterpillar track 130, the caterpillar track 130 can walk like a flat place in a complex construction site, so that the construction speed is greatly improved and the mechanized operation quality is relatively guaranteed.
[0036] Reference Figure 1 As shown, in some embodiments provided in the present application, the paint supply assembly comprises a storage barrel 810, a material conveying pipe 820 and a conveying pump 830. The storage barrel 810 is used for containing paint, one end of the material conveying pipe 820 communicates with the storage barrel 810, the other end communicates with the paint spraying assembly, and the conveying pump 830 is installed on the material feeding section of the material conveying pipe 820 and is used for conveying paint to the paint spraying assembly.
[0037] In some specific embodiments, the lifting arm 200 is a hollow arm, a cavity extending along the length direction of the lifting arm 200 is formed in the lifting arm 200, the material conveying pipe 820 is a flexible pipe, and the material conveying pipe 820 extends out of the cavity in the lifting arm 200, so as to convey paint to the upper end of the lifting arm 200.
[0038] In some specific embodiments, a liquid level sensor is arranged on the inner wall of the storage barrel 810 and is used for detecting the liquid level of the paint in the storage barrel 810, so as to prevent the paint in the storage barrel 810 from being too little and avoid uneven paint spraying surface caused by too little paint.
[0039] Reference Figure 2 , Figure 3As shown, in some embodiments of this application, the support frame 300 includes a first arc-shaped arm 310 and a second arc-shaped arm 320. One end of the first arc-shaped arm 310 is fixed with a rotating shaft 330, which rotatably engages with one end of the second arc-shaped arm 320. The second arc-shaped arm 320 can open or close its other ends by rotating around the rotating shaft 330. Specifically, the second arc-shaped arm 320 is connected to the output rod of a hydraulic cylinder. The extension of the output rod of the hydraulic cylinder can drive the second arc-shaped arm 320 to rotate around the rotating shaft 330, presenting an open state; the retraction of the output rod of the hydraulic cylinder can drive the second arc-shaped arm 320 to rotate around the rotating shaft 330, presenting a closed state. When the other ends of the first arc-shaped arm 310 and the second arc-shaped arm 320 are open, the pile head to be derusted and painted can be inserted between the first arc-shaped arm 310 and the second arc-shaped arm 320 through the opening. When the other ends of the first arc-shaped arm 310 and the second arc-shaped arm 320 are closed, the first arc-shaped arm 310 and the second arc-shaped arm 320 form a ring, which surrounds the pile head to be derusted and painted, making it convenient to derust and paint the surface of the pile head.
[0040] Reference Figure 4 As shown, in some specific embodiments, an upper chamber 311 and a lower chamber 312 are respectively provided on the inner sides of the first arc-shaped arm 310 and the second arc-shaped arm 320. The painting component is located in the upper chamber 311, and the laser component is located in the lower chamber 312. By placing the painting component in the upper chamber 311 and the laser component in the lower chamber 312, during the top-down rust removal and painting process of the pile head, the laser component in the lower chamber 312 first removes rust from the upper end of the pile head. After the upper end of the pile head is rusted, the lifting arm 200 moves down, and the laser component in the lower chamber 312 continues to remove rust from the surface of the pile head below. At the same time, the painting component in the upper chamber 311 reaches the original height of the laser component and paints the surface of the rust-removed pile head. In this way, rust removal or painting can be performed simultaneously at different heights of the same pile head, which can effectively improve the efficiency of rust removal and painting of the pile head.
[0041] Reference Figure 4 As shown, in some specific embodiments, the laser assembly includes laser emitters 400 that are uniformly distributed circumferentially in the lower chamber 312.
[0042] In some specific embodiments, a negative pressure head 500 is also provided in the lower chamber 312, located on the upper and lower sides of the laser emitter 400. Specifically, a negative pressure device is provided on the frame 110, and the negative pressure device is connected to the negative pressure head 500 through a flexible hose. In this way, during the laser rust removal process, the dust and iron filings generated can be promptly sucked away by the generated negative pressure, preventing the dust and iron filings from falling back onto the undried paint surface.
[0043] Reference Figure 4As shown, in some specific embodiments, the painting assembly includes nozzles 600 evenly distributed circumferentially in the upper chamber 311, the nozzles 600 being connected to a feed pipe 820 for spraying paint onto the surface of the pile head.
[0044] In some specific embodiments, an air blowing head 700 is also provided in the upper chamber 311, located on the upper and lower sides of the nozzle 600. Specifically, a blower is also provided on the frame 110, and the blower is connected to the air blowing head 700 via a hose. Thus, before painting, blowing air through the air blowing head 700 onto the rust-removed area can clean away the dust and iron filings generated during the rust removal process; during painting, blowing air through the air blowing head 700 onto the area being painted can cool the painted area and increase the speed of paint drying.
[0045] In some embodiments of this application, the device further includes a laser alignment sensor, which is disposed on the support frame 300. Specifically, the laser alignment sensor is installed on the inner side of the first arc-shaped arm 310 and the second arc-shaped arm 320, located on the partition between the first arc-shaped arm 310 and the second arc-shaped arm 320, and is used to detect the position of the support frame 300 relative to the pile head. This ensures that the ring enclosed by the first arc-shaped arm 310 and the second arc-shaped arm 320 remains coaxial with the pile head, guaranteeing the consistency of the paint thickness.
[0046] The workflow of the automated pile head rust removal and painting device in this application is as follows:
[0047] The lifting arm 200 is raised to align the first arc-shaped arm 310 and the second arc-shaped arm 320 with the top of the pile head, and then the pile head is derusted and painted from top to bottom. The laser assembly in the lower chamber 312 first derusts the upper end of the pile head. After the upper end of the pile head is derusted, the lifting arm 200 moves down, and the laser assembly in the lower chamber 312 continues to derust the surface of the pile head below. Simultaneously, the painting assembly in the upper chamber 311 reaches the original height of the laser assembly and paints the surface of the derusted pile head. In this way, different heights of the same pile head can be derusted or painted simultaneously, effectively improving the efficiency of rust removal and painting of the pile head.
