Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete pouring, in particular to a cast-in-place concrete pavement troweling device with self-cleaning function. BACKGROUND

[0002] During the pouring process of concrete, due to the poor flowability of concrete itself, small imperfections such as unevenness will appear on the bottom surface of the poured concrete. In order to ensure the neatness of the concrete pavement, the protrusions generated during the pouring of concrete need to be polished and flattened to maintain the flatness of the concrete pavement.

[0003] The existing patent (publication number: CN111379207A) discloses a handheld troweling device for concrete road construction. The handheld troweling device for concrete road construction realizes the function of driving the troweling disc to rotate and troweling the concrete road through a driving mechanism. Compared with the existing driving mechanism, the driving mechanism also improves safety. Furthermore, the auxiliary mechanism realizes the function of cleaning the troweling disc. Compared with the existing auxiliary mechanism, the auxiliary mechanism combines inertia and vibration in two ways, and the cleaning effect is better. In the process of realizing the present application, the inventors found that the following problems in the prior art have not been solved: 1. After the troweling disc of the device completes the troweling operation of the concrete bottom surface, the surface is contaminated with a large amount of concrete residue. If the residue is not cleaned in time, the surface of the troweling disc will be rusted and perforated, resulting in a decrease in the troweling quality of the device; 2. When the device is processing the ground with large undulations of concrete pouring, additional personnel are needed to spread the concrete in order to perform the troweling work, resulting in an increase in the use cost of the device; 3. The device has a fixed advancing direction during the concrete troweling operation, and the construction environment is complex and variable. It is difficult and time-consuming to trowel the corners and the efficiency is low.

[0004] In addition, although the existing other concrete pavement troweling device adopts a fixed filter sleeve to scrape and filter the concrete material on the bottom rotating troweling disc, the filter sleeve is arranged in the rotating path of the troweling disc, so that the bottom of the filter sleeve undesirably scrapes the concrete material.

[0015] Beneficial effects

[0016] The present application provides a cast-in-place concrete pavement finishing device with self-cleaning function.

[0017] (1) In the present application, the limiting slide rail located above the rotating plane of the finishing disc and the magnet embedded in the limiting slide rail and the finishing disc enable the scrubbing plate to be lifted and guided without being arranged on the rotating path of the finishing disc during filtering and scraping, so that multiple finishing discs are lifted in turn and are scrubbed, and are buffered due to the magnetic attraction when falling down, without falling directly to cause the concrete material to be broken.

[0018] (2) The cast-in-place concrete pavement finishing device with self-cleaning function completes the cleaning and protection of the finishing disc through the guardrail, the protective net, the cleaning mechanism, the fixing rod, the sleeve, the limiting slide rail, the scrubbing plate, the rotating shaft and the finishing disc. During the rotation of the rotating shaft, the limiting slide rail adjusts the rotating position of the finishing disc, the finishing disc enters the inner side of the scrubbing plate, and the concrete blocks adhered to the surface of the finishing disc are scraped off, so as to avoid that the concrete blocks remaining on the surface of the finishing disc leave scratches on the finished concrete pavement. The waterless scrubbing of the scrubbing plate improves the cleaning and protection of the finishing disc.

[0019] (3) The self-cleaning cast-in-place concrete pavement finishing device reduces the finishing of the road by the flattening mechanism, the splash-proof shell, the second motor, the first chain wheel, the chain, the second chain wheel, the flattening roller and the scraper. When the road flattening operation is performed, there are areas with uneven thickness of the concrete due to non-standard concrete pouring operation. Workers need to adjust the thickness of the concrete during the flattening operation. The second motor is started to drive the flattening roller through the first chain wheel, the chain and the second chain wheel. The uneven and large undulating concrete is pushed and scattered by the flattening roller, which facilitates the finishing of the road surface by the finishing disc. The concrete adhered to the outside of the flattening roller is removed by the baffle. No additional concrete spreading personnel is needed, which reduces the construction cost and the equipment use cost.

[0020] (4) The self-cleaning cast-in-place concrete pavement finishing device improves the efficiency of the corner and edge finishing by the top plate, the rotating seat, the direction adjusting mechanism, the return spring, the limiting pin and the limiting hole. When the road flattening in some corner areas is processed, the position of the limiting pin on the limiting hole is adjusted to adjust the advancing direction of the flattening roller and the polishing plate, which facilitates workers to directly flatten the road in the corner under the condition that the finished finishing operation road surface is not damaged. The flattening route does not need to be adjusted by the advancing direction of the device, which improves the flattening efficiency of the device. BRIEF DESCRIPTION OF DRAWINGS
