Description

Technical Field

[0001] The utility model relates to the technical field of concrete roughening, in particular to a concrete surface roughening and cleaning device based on high-pressure water jet. Background Technique

[0002] Roughening is to use an ax-like tool to chisel out indentations on the completed concrete structure surface. Its function is to make the construction surfaces of two construction stages bond firmly. Simply put, the concrete surface is roughened with a drill and then washed clean with water. The main purpose is to increase the bonding force between the post-poured concrete and it.

[0003] For the existing concrete surface cleaning equipment after roughening, such as the concrete structure surface roughening and cleaning device disclosed in the patent publication number CN221790217U, through the setting of the cleaning end head, the roughened part can be washed, and the cleaning roller brush can rotate, so that the cleaning roller brush can clean the attached dust and concrete blocks, and the roughened concrete structure surface can be effectively cleaned. Through the action of the dust suction fan, gas can enter through the dust suction end head and be discharged through the suction box, so that the carried cleaning dust can circulate in the air. Then, the flying dust can enter the dust collection net frame through the telescopic hose and the dust suction pipe, and the dust can be blocked and collected by the dust collection net frame.

[0004] In the above patent, the cleaning roller brush rotates to sweep the dust and debris on the concrete surface forward and cooperate with the dust suction end head to suck in the dust. However, since the dust suction end head is perpendicular to the ground, when the cleaning roller brush sweeps the dust and debris forward, it will quickly pass under the dust suction end head, resulting in poor dust suction effect. At the same time, when using the cleaning end head to wash, the cleaning water remains on the concrete surface, which is inconvenient to scrape the cleaning water, and construction workers are prone to step on the water, making it not very convenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a concrete surface roughening and cleaning device based on high-pressure water jet, so as to solve the problems put forward in the above background technique that the dust suction end head is perpendicular to the ground, when the cleaning roller brush sweeps the dust and debris forward, it will quickly pass under the dust suction end head, resulting in poor dust suction effect, and at the same time, when using the cleaning end head to wash, the cleaning water remains on the concrete surface, which is inconvenient to scrape the cleaning water, and construction workers are prone to step on the water, making it not very convenient to use.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer toFigure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present utility model provides a technical solution: a concrete surface roughening and cleaning device based on high-pressure water jets, including a base 1 and moving wheels 2 installed at the four corners of the bottom of the base 1. A cleaning assembly 3 is movably installed at the bottom of the base 1, a flushing assembly 6 is fixedly installed at the bottom of the base 1 behind the cleaning assembly 3, and a scraping and sweeping assembly 7 is movably installed at the bottom of the base 1 behind the flushing assembly 6; the cleaning assembly 3 includes a telescopic electric cylinder one 31 fixedly installed at the top of the base 1. The bottom of the telescopic electric cylinder one 31 is fixedly installed with a lifting frame 32 located below the base 1. An installation frame 33 is movably clamped inside the lifting frame 32. A cleaning roller brush 34 is movably installed inside the installation frame 33. A motor 35 connected to the cleaning roller brush 34 is fixedly installed outside the installation frame 33. A dust-proof frame 36 is movably hinged to the front side of the installation frame 33. A support frame 37 is fixedly installed on the front side of the telescopic electric cylinder one 31. A telescopic electric cylinder two 38 is movably hinged between the inner side of the support frame 37 and the outer side of the dust-proof frame 36. A dust suction cover 39 is fixedly installed inside the dust-proof frame 36. A dust suction pipe 310 is fixedly connected to the outside of the dust suction cover 39. The cleaning roller brush 34 is rotated by the motor 35 to sweep dust and debris forward. By controlling the extension of the telescopic electric cylinder two 38, the dust-proof frame 36 rotates around the connection point of the installation frame 33, and the dust-proof frame 36 inclines towards the cleaning roller brush 34, effectively intercepting dust during the cleaning process and ensuring the dust suction effect. The concrete fragments are continuously swept forward by the cleaning roller brush 34 and collected centrally, thereby ensuring the full cleaning of dust and fragments.

[0024] A mesh plate is arranged inside the dust suction cover 39, and a buffer pad 311 is fixedly installed below the inner side of the dust-proof frame 36. The design of the mesh plate can effectively prevent large concrete fragments from entering the inside of the dust suction cover 39, avoid blockage, and ensure the smooth operation of the dust suction system. The setting of the buffer pad 311 can play a buffering role when the dust-proof frame 36 contacts the fragments swept forward, reduce impact noise, protect the equipment from damage, and extend its service life.

[0025] Guide columns 312 are fixedly connected to the left and right sides inside the telescopic electric cylinder one 31. The installation frame 33 is movably clamped outside the guide columns 312. A spring 313 is movably sleeved outside the guide columns 312 above the installation frame 33. When the telescopic electric cylinder one 31 drives the lifting frame 32 to descend, the installation frame 33 can float up and down to a certain extent on the guide columns 312, so as to adapt to different cleaning requirements, avoid hard contact from damaging the equipment. At the same time, the elastic effect of the spring 313 can effectively relieve the vibration during the cleaning process, improve the stability and durability of the equipment.

[0026] Please refer to Figure 1 andFigure 2 , a dust collection box 4 is fixedly installed in front of the top of the base 1. A dust suction fan 5 communicated with the dust collection box 4 is fixedly installed on the top of the dust collection box 4. The dust collection box 4 is communicated with a dust suction pipe 310. After the dust suction fan 5 is started, the dust collected in the dust suction hood 39 is sucked into the dust collection box 4 through the dust suction pipe 310, achieving efficient cleaning, avoiding the influence of dust on the surrounding environment and construction personnel. A detachable filter plate is arranged in the dust collection box 4, which can filter the dust and is convenient for disassembly and cleaning, ensuring the continuous and efficient operation of the equipment.

[0027] Please refer to Figure 2 and Figure 5 , the flushing assembly 6 includes a shunt pipe 61 fixedly installed at the bottom of the base 1. Flushing nozzles 62 are fixedly installed at equal intervals at the bottom of the shunt pipe 61. A water delivery pipe 63 is fixedly connected to the top of the shunt pipe 61; the scraping and sweeping assembly 7 includes a telescopic electric cylinder three 71 fixedly installed on the top of the base 1. A connecting plate 72 arranged in an arc shape is fixedly connected to the bottom of the telescopic electric cylinder three 71. A cleaning brush 73 is fixedly installed at the bottom of the connecting plate 72. Water is delivered to the pump through the water delivery pipe 63, and then is delivered to the flushing nozzles 62 through the shunt pipe 61, and is sprayed onto the concrete surface in the form of high-pressure water jets for cleaning. The telescopic electric cylinder three 71 is controlled to lower the connecting plate 72, and the cleaning brush 73 contacts the concrete surface accordingly. The cleaning brush 73 surrounds the shunt pipe 61. As the base 1 moves, the cleaning brush 73 can scrape the cleaning water forward, thereby reducing the residual cleaning water on the concrete surface.

[0028] A guide rod 74 penetrating the base 1 is fixedly connected to the top of the connecting plate 72. The guide rods 74 are arranged symmetrically left and right, which can play a guiding role in the movement of the connecting plate 72, making the connecting plate 72 more stable during the movement and improving the stability and safety of the equipment.

[0029] Working principle: During use, the base 1 is pushed to move. The telescopic electric cylinder one 31 is controlled to drive the lifting frame 32 to descend, so that the cleaning roller brush 34 in the mounting frame 33 contacts the concrete surface. Subsequently, the motor 35 is started to drive the cleaning roller brush 34 to rotate, and the dust and debris on the surface are swept forward. By starting the dust suction fan 5, the dust is sucked through the dust suction fan 5 from the dust suction hood 39 connected to the dust suction pipe 310 via the dust collection box 4. By controlling the telescopic electric cylinder two 38 to extend, the dust blocking frame 36 is driven to rotate along the connection with the mounting frame 33, so that the dust blocking frame 36 is inclined towards the cleaning roller brush 34 direction, which can effectively intercept and suck the swept dust, ensuring the dust suction effect. The dust is sucked into the dust collection box 4 through the dust suction pipe 310. A filter screen is arranged in the dust collection box 4, which can filter the dust and discharge the air through the dust suction fan 5, completing the collection of the dust. The concrete debris is continuously swept forward by the cleaning roller brush 34 for centralized collection;

[0030] Connect the water pipe pumping water source to the shunt pipe 61 through the water delivery pipe 63 and spray high-pressure water jets from the flushing nozzle 62 onto the concrete surface to wash the concrete surface. At the same time, drive the connecting plate 72 to descend by controlling the telescopic electric cylinder three 71, so that the cleaning brush 73 contacts the concrete surface. Since the cleaning brush 73 is made of wear-resistant and soft material and surrounds the outside of the shunt pipe 61, it can scrape the cleaning water flow forward as the base 1 moves, reducing the residue on the concrete surface. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
