Concrete pavement broom-finish device

Abstract

The invention relates to the technical field of concrete pouring devices, in particular to a concrete pavement broom-finish device. The concrete pavement broom-finish device comprises a broom-finish machine, a push rod and a base. A translational track is arranged on the base, a sliding base capable of moving along the translational track is arranged on the translational track, the sliding base is fixedly connected with the push rod, so that leveraged supporting is formed to the push rod, and a short moment end of the push rod is hinged to the broom-finish machine; and thin film rollers are arranged at the two ends of the base correspondingly, and thin film hooks are arranged on the front side and the rear side of the broom-finish machine correspondingly. According to the concrete pavement broom-finish device, the structure is reasonable, the linearity and the distance of a pavement pattern is controlled by the broom-finish machine through the translational track on the base, the broom-finish machine is fixed on the sliding base through the hard push rod, and the broom-finish strength is adjusted through the lever principle so that adjustment can be conducted according to the concrete strength to ensure the depth consistency of the broom-finish pattern; and the length of the base can be adjusted through a telescopic rod, the broom-finish requirements for pavements with different widths are met, thin film laying is once finished along with broom-finish operation, and the time and the labor cost can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of concrete pouring devices, in particular to a roughening device for concrete pavement. Background technique [0002] Cement concrete pavement is smoother than asphalt pavement, and its surface friction coefficient is low and its anti-skid performance is poor. It is easy to affect driving safety in rainy weather. Therefore, the cement concrete surface of the road needs to be roughened and grooved. friction, improve the anti-skid performance of the road surface. The quality of the napping operation can directly affect the smoothness, roughness and anti-wear performance of the road surface. After the cement concrete pavement is plastered, when a dent with a depth of about 2mm appears when the index finger is slightly pressed, it is the best time for roughening, and the roughening depth is 1-2mm. The existing napping device is a napping device equipped with a long bamboo pole, combined with the self-weight o...

Problems solved by technology

The existing napping device is a napping device equipped with a long bamboo pole, combined with the self-weight of the napping device and manual thrust to achieve the effect of stretching, but the quality of the napping is limited by the operation, there are problems such as uneven texture depth and unsmooth linearity, and it cannot be adjusted according to the concrete strength With its own weight, the linearity, spacing, and depth of the pull marks do not meet the uniform requirements
