[0024] Figure 1 This is a structural schematic diagram of the expansion joint cleaning device in an embodiment of this utility model. Figure 2 This is a schematic diagram of the internal structure of the expansion joint cleaning device in an embodiment of this utility model.

[0025] like Figure 1-2 As shown, the expansion joint cleaning device 1 in this embodiment includes a suction frame 100, a suction assembly 200, a spraying assembly 300, and a sealing assembly 400, which are connected to a water tank, a garbage collection bin, and a high-pressure centrifuge. It is used to clean small garbage in the expansion joints of roads and bridges and suck it into the garbage collection bin.

[0026] The suction frame 100 is connected to the garbage collection bin and is used to suck garbage into the garbage collection bin.

[0027] The suction port assembly 200 is connected to the high-pressure centrifuge. There are two suction port assemblies 200, which are fixed downwardly on the left and right sides below the suction port frame 100 and are used to suck up small debris in the expansion joints of the road and bridge.

[0028] The suction body 210 ensures normal airflow and proper installation of the spray washing assembly 300. The suction body 210 has a trapezoidal structure and consists of two separate suction ports with the same structure and function, one on the left and one on the right. The two separate suction ports share a single suction port outlet.

[0029] The suction port assembly 200 includes: a suction port body 210, a rubber suction port 220, and a channel 230.

[0030] The suction port body 210 is fixed to the lower part of the suction port frame 100 and is connected to the suction port frame 100.

[0031] The rubber suction port 220 is surrounded by a 5mm thick soft rubber plate around the lower part of the suction port and is fixed to the inlet of the suction port body 210 by bolts. It extends 50-60mm from the lower part of the suction port, has a working height of 20mm, and corresponds to the spray washing component 300. It is used to suck up small debris in the expansion joints of the road and bridge, and can avoid damage caused by bumps on the road surface.

[0032] Channel 230 is formed in the upper part of the suction port body 210 and corresponds to the spray washing assembly 300. The channel 230 enables the high-pressure liquid sprayed by the spray washing assembly 300 to be sprayed out through the rubber suction port 220.

[0033] Figure 3 This is an enlarged schematic diagram of the spray washing component 300 at point B in an embodiment of this utility model.

[0034] like Figure 3 As shown, the spray washing assembly 300 is hinged to the upper part of the suction assembly 200 and is used to wash small debris inside the expansion joint of the road bridge, regardless of the depth of the expansion joint.

[0035] The spray assembly 300 includes: a mounting frame 310, a high-pressure nozzle 320, and a nozzle connector 330.

[0036] The mounting frame 310 is rotatably mounted on the upper part of the suction port body 210.

[0037] The mounting frame 310 includes: a hinge plate 311, a nozzle housing 312, a viewing window 313, a handle 314, a first strong magnet 315, and a second strong magnet 316.

[0038] The hinge plate 311 is rotatably hinged to the upper part of the suction port body 210, and a first strong magnet 315 is fixed to the bottom of the hinge plate 311.

[0039] The second strong magnet 316 is fixed to the upper part of the suction port body 210 and is attracted to the first strong magnet 315. The connection stability between the hinge plate 311 and the suction port assembly 200 is enhanced by the attraction between the first strong magnet 315 and the second strong magnet 316.

[0040] The nozzle housing 312 is fixed to the top of the hinge plate 311 and is fixedly connected to the high-pressure nozzle 320. The nozzle housing 312 is trapezoidal in shape and has a viewing window 313 installed on it for observing the working status of the high-pressure nozzle 320. The viewing window 313 is made of transparent polycarbonate material with a thickness of 5mm.

[0041] The handle 314 is fixed to the lower side of the nozzle housing 312. The handle 314 makes it easy to apply external force to the nozzle housing 312 to open it, so as to rotate the spray washing assembly 300 to clean the residual garbage inside.

[0042] The high-pressure nozzle 320 is fixed to the top of the mounting frame 310 and corresponds to the rubber suction port 220, used to spray high-pressure cleaning liquid. The high-pressure nozzle 320 is a high-pressure rotating nozzle that sprays a high-pressure cone-shaped water jet with a nozzle diameter of 0.3 mm and a pressure of 120 kg / cm². 2 The flow rate under pressure is 11 L / min.

[0043] The nozzle connector 330 is fixed to the top of the high-pressure nozzle 320 and connected to the water tank for connecting the water tank and the high-pressure nozzle 320 and supplying water to the high-pressure nozzle 320.

[0044] The nozzle connector 330 is made of brass and measures 30×30×200 (mm). The thread at the high-pressure hose connection is M16×1.25, and the thread at the high-pressure nozzle 320 is PT1 / 8. The two internal threads are 100mm apart.

[0045] Figure 4 This is an enlarged schematic diagram of the sealing component 400 at point A in an embodiment of this utility model.

[0046] like Figure 4 As shown, the sealing component 400 is rotatably mounted on the lower part of the suction port component 200 for sealing the suction port component 200.

[0047] The sealing assembly 400 includes: a drive unit 410, a rotating shaft 420, an internal damper 430, and a damper baffle 440.

[0048] Figure 5 This is a schematic diagram of the structure of the driving device 410 in an embodiment of this utility model.

[0049] like Figure 5 As shown, the drive device 410 drives the rotating shaft 420 to rotate, and the rotating shaft 420 drives the internal damper 430 to move, thereby opening and closing the air duct of the suction assembly 200.

[0050] The drive unit 410 is installed on the front side of the suction port body 210. The drive unit 410 includes: a cylinder 411, a swing arm 412, a slide rail 413, and a drive head 414.

[0051] After being fixed, cylinder 411 is located on the front side of the suction port body 210. A swing arm 412 is fixed to the end of the rotating shaft 420 and rotates under the drive of cylinder 411, thereby causing the rotating shaft 420 to rotate. A slide rail 413 is formed on the swing arm 412. A drive head 414 is fixed to the end of cylinder 411 and slides along the slide rail 413, thereby enabling cylinder 411 to push the swing arm 412 to rotate.

[0052] Cylinder 411 and rocker arm 412 are the power source for opening and closing the internal damper 430. The model is Airtac MAL40×100-CA. The extension and retraction of cylinder 411 pushes the rocker arm to keep the internal damper 430 in the closed or open state. Through electrical interlock, only one cylinder 411 is allowed to operate during normal operation.

[0053] The combination of slide rail 413 and drive head 414 enables cylinder 411 to drive swing arm 412 to rotate normally.

[0054] The rotating shaft 420 is fixed on the drive device 410 and extends into the interior of the suction port body 210.

[0055] The internal damper 430 is fixed inside the rotating shaft 420 and connected to the drive device 410 through the rotating shaft 420. The internal damper 430 is made of 5mm thick steel plate and serves to open and close the left and right suction ducts.

[0056] In this embodiment, the internal damper 430 and the drive device 410 are connected by the rotating shaft 420, so that the drive device 410 can drive the internal damper 430 to rotate, and the internal damper 430 can be adjusted back and forth between the blocking state and the air guiding state.

[0057] The damper baffle 440 is fixed inside the suction body 210 and is fixedly connected to the internal damper 430 to limit the rotation angle of the internal damper 430.

[0058] In this embodiment, the damper 440 is blocked by the damper 440, which limits the rotation angle of the damper 440. At the same time, it is sealed with the internal damper 430 to block the suction port body 210.

[0059] The working method of this utility model:

[0060] The suction port is only part of the expansion joint cleaning device 1. Other devices that work with it include a high-pressure centrifugal fan that generates vacuum suction, a high-pressure water pump that generates high-pressure cleaning water, a cleaning water recycling system, and a garbage collection box for collecting and storing mud, sand, and garbage generated after the expansion joint cleaning. The suction port and the above devices together form a complete cleaning system.

[0061] During suction operation, high-pressure water supplied by the high-pressure water pump is sprayed out through two high-pressure nozzles 320, directly onto the sawtooth expansion joint that needs to be cleaned, loosening and scattering the mud and sand inside the expansion joint, while cleaning the gaps inside the expansion joint. At this time, the vacuum suction generated by the high-pressure centrifugal fan acts on the suction outlet through the garbage collection box, internal filter, internal air duct and corrugated hose. When the cylinder 411 on the left side of the suction port extends, it pushes the swing arm 412 to open the left internal air door 430. Under the action of vacuum suction, air enters the suction port from the gap between the rubber suction port 220 and the ground. Together with the mud, sand, garbage, and cleaning water loosened and scattered by the high-pressure water, it enters the garbage collection box through the main suction channel 230, internal air door 430, suction port frame 100 and connected corrugated hose, completing the cleaning of the sawtooth expansion joint.

[0062] The role and effect of the embodiments

[0063] According to the expansion joint cleaning device involved in this utility model, the high-pressure rinsing of the spray washing component cleans the internal gaps of the expansion joint, and is not affected by the depth of the expansion joint; the suction of the suction component sucks up the mud, garbage and water used for cleaning from the expansion joint, which not only achieves thorough cleaning of the internal gaps of the expansion joint, but also collects the mud, garbage and cleaning water at one time, ensuring a clean and beautiful work site.

[0064] This invention facilitates observation of the working status of the high-pressure nozzle through the setting of a viewing window.

[0065] This invention ensures the stability of the hinge plate during use by setting a first strong magnet and a second strong magnet, preventing the nozzle housing from jumping or opening under the reaction force of the water sprayed from the high-pressure nozzle.

[0066] This invention, through the setting of a hinge plate, allows the spray washing assembly to be opened by rotation, thereby making it convenient for users to clean the garbage inside the suction port and at the nozzle.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
