Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete parts, in particular to a prefabricated concrete part brushing device. Background Art

[0002] Precast concrete parts refer to concrete products that are processed and produced in a standardized and mechanized manner in a factory. In contrast, traditional cast-in-place concrete requires on-site molding, pouring and maintenance. Precast concrete parts are widely used in the fields of construction, transportation, water conservancy, etc., and play an important role in the national economy. Precast concrete parts need to be brushed on the surface before solidification. Brushing is a commonly used surface treatment method. Its functions include increasing the roughness of the concrete surface, improving anti-slip performance, enhancing the adhesion of concrete to other materials, and improving the appearance of the surface.

[0003] Currently, there is equipment for brushing precast concrete parts after they are cast in molds. A fixed strip brush is installed above a conveyor belt. When the precast concrete parts pass under the strip brush, they can be brushed under the relative movement force. However, most precast concrete parts are customized according to customer needs. The thickness of the precast concrete parts is different, and the height and brush angle of the fixed height strip brush are difficult to adjust, resulting in shallower bristles for thin parts and deeper bristles for thick parts. The quality of the precast concrete parts after brushing is uneven, which affects the roughness of the concrete surface and reduces the anti-slip performance and adhesion. Utility Model Content

[0004] The utility model aims to provide a precast concrete part brushing device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A concrete precast part brushing device comprises: a conveying platform and a brush structure; a stand is welded on the upper surface of the conveying platform; the brush structure is arranged on the top of the stand, and the brush structure comprises a connecting frame connected to a cylinder by bolts and welded to the bottom end of a cylinder push rod, an insertion shaft inserted into the connecting frame, a nut threadedly connected to one end of the insertion shaft, and a brush strip welded to the outer wall of the insertion shaft.

[0007] By adopting the above technical solution, the plug shaft can be rotated by loosening the nut, so that the brush bar can be rotated to adjust the angle of the brushing treatment, and the nut can be tightened to fix it. The height of the brush bar can be adjusted using a cylinder, and the appropriate height can be adjusted according to the thickness of the precast concrete part for brushing treatment. The surface roughness of the precast concrete part can be unified, and the anti-slip performance and adhesion of the surface of the precast concrete part can be improved.

[0008] Preferably, the upper surface of the brush strip is provided with a self-cleaning structure, which includes a fixed head welded on the upper surface of the brush strip, a transverse tube arranged on the fixed head, a high-pressure nozzle arranged on the lower surface of the transverse tube and a hose connected to one end of the transverse tube.

[0009] By adopting the above technical solution, by installing a horizontal pipe with a high-pressure nozzle on the brush bar, clean water can be transported by a hose and the high-pressure nozzle can be used to flush the brush bar, so that the adhered concrete can be flushed down, thereby realizing the self-cleaning treatment of the brush bar, solving the problem of the difficulty in cleaning the disassembled brush bar, and avoiding the problem of the solidification of the adhered concrete due to the long-term use of the brush bar, so as to ensure that the brush bar is brushed in a normal form.

[0010] Preferably, a waterproof cover is welded to the outer wall of the stand, one end of the hose passes through the top of the waterproof cover, an electric valve is provided on the upper surface of the waterproof cover, and the hose is plugged into the water outlet of the electric valve.

[0011] By adopting the above technical solution, by using an electric valve set on the hose, the electric valve can be used to remotely control the delivery of clean water, so as to achieve the effect of cleaning without the need for workers to operate, avoid the problem of sticking concrete solidification due to forgetting to clean, and improve the convenience and efficiency of the use of the device.

[0012] Preferably, the transverse tube and the brush strip are arranged relatively parallel to each other, and the high-pressure nozzle is located in the middle of the width of the brush strip.

[0013] By adopting the above technical solution and setting the positions of the transverse pipe and the high-pressure nozzle, the high-pressure nozzle can be used to spray clean water to cover the entire brush strip, thereby improving the cleaning effect of the brush strip.

[0014] Preferably, a conveying structure is provided inside the conveying platform, and the conveying structure includes a conveyor belt arranged on the inner wall of the conveying platform, a support plate welded to the inner wall of the conveying platform, a water collecting trough opened at the bottom of the conveying platform, and a drainage pipe welded to the water collecting trough.

[0015] By adopting the above technical solution, more waste water will be generated during cleaning through the self-cleaning structure. The waste water can be made to flow into the bottom sump through the conveyor belt for collection, and then climb out through the drain pipe to ensure that the waste water can be collected and treated, avoid waste water turbulence polluting the workshop, and improve the environmental friendliness of the device.

[0016] Preferably, the conveyor belt is a stainless steel chain belt, a water leakage hole is opened on the support plate, and the support plate is located below the upper half of the conveyor belt.

[0017] By adopting the above technical solution, by using a support plate to support the upper part of the conveyor belt, the conveyor belt can be moved on the support plate to ensure that the heavier concrete precast parts can be transported stably, reducing the quality of the brushing treatment caused by violent sliding of the conveyor. At the same time, a stainless steel chain belt and a support plate with leakage holes are used to facilitate the waste water to easily fall to the bottom for collection and treatment during cleaning.

[0018] Preferably, the brush strip is made of alumina sand, and the length of the brush strip is ten centimeters and the width is five centimeters.

[0019] By adopting the above technical scheme, the brush strips are made of aluminum oxide sand, which is a concrete roughening material with high hardness, wear resistance, anti-slip and corrosion resistance, so as to improve the service life of the brush strips used for a long time. The particle size of aluminum oxide sand is relatively fine, which can form uniform fine lines and fine granularity, making the concrete surface more beautiful, and also increasing the anti-slip and anti-corrosion properties of the concrete surface. At the same time, the length and overall width of the brush strips are set to ensure that there are sufficient bristles to contact the concrete surface for treatment, thereby improving the effect of the brush treatment.

[0020] Preferably, the length of the brush strip is the same as the width of the conveyor belt, and the lower surface of the waterproof cover is located in the middle of the stand.

[0021] By adopting the above technical solution, by setting a brush strip with the same width as the conveyor belt, it is ensured that the surface of the prefabricated parts within the conveyable range can be brushed, thereby improving the practicality of the device. At the same time, the waterproof cover can ensure that the waste water splashed by the brush strip moving to the inside for cleaning can be covered while the prefabricated parts pass through, thereby preventing the waste water from splashing and polluting the workshop.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) By loosening the nut, the plug shaft can be rotated to adjust the angle of the brush treatment, and the nut can be tightened to fix it. The height of the brush bar can be adjusted using a cylinder. The appropriate height can be adjusted according to the thickness of the precast concrete part. When the precast concrete part moves under the brush bar, regular patterns will be drawn on the surface during the relative movement to complete the brush treatment. The surface roughness of the precast concrete part can be unified, thereby improving the anti-slip performance and adhesion of the surface of the precast concrete part;

[0024] (2) By installing a horizontal pipe with a high-pressure nozzle on the brush bar, clean water can be transported through a hose and the high-pressure nozzle can be used to flush the brush bar, so that the adhered concrete can be flushed off, thereby achieving self-cleaning of the brush bar, solving the problem of difficult cleaning of the brush bar after disassembly, and avoiding the problem of solidification of adhered concrete due to long-term use of the brush bar, so as to ensure that the brush bar is brushed in a normal form.
