[0019] A construction method for removing an auxiliary device for a bridge on a highway comprises the following steps:

[0020] S1.

[0021] S2. After adjustment, the construction vehicle moves forward, so that the road gravel is collected by the adjustable scrapers and fixed scrapers on both sides and concentrated under the feeding cylinder. At this time, the second motor drives the spiral shaft to rotate, and the spiral shaft transports the gravel upward, so that the gravel enters the recycling box through the telescopic cover, and then the first motor drives the first rotating shaft to rotate, so that the gravel passes through the grid plate, and then passes through the upper filter screen for primary filtration, and then passes through the lower filter screen for secondary filtration, so as to perform classification, and finally the fine particles fall into the bottom of the recycling box;

[0022] S3. During the feeding process of the spiral shaft, the spiral shaft also drives the first gear and the second gear to transmit, so that the second gear drives the crankshaft to rotate, the crankshaft drives the hollow frame to reciprocate, the hollow frame drives the slider to reciprocate, and the rollable brush reciprocates to clean the road surface. During the cleaning process, the vacuum cleaner performs vacuuming by fixing the vacuum head and adjusting the vacuum head, and recycles the dust into the recycling box for collection.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The auxiliary device and construction method for dismantling a bridge on a highway, through the retraction of the second electric push rod, drives the telescopic frame to unfold through the sliding sleeve, and after the telescopic frame is unfolded, it can drive the adjustable scraper to unfold, and the adjustable scraper can drive the support plate to move, so that the reel releases the reelable brush to achieve the purpose of unfolding, and the support plate also drives the adjustable dust head to unfold in sequence, so that it can adapt to the width of the road surface, thereby simultaneously adjusting the gravel scraping area, the cleaning area and the dust suction area, meeting the needs of automatic adjustment, and at the same time improving the road surface processing efficiency;

[0025] 2. The auxiliary device and construction method for dismantling the bridge on the expressway can make the adjustable scraper and the fixed scraper scrape the material smoothly through the moving operation of the construction vehicle. Since the fixed scraper and the adjustable scraper form a V-shaped structure, the crushed stone can be guided to the bottom of the feeding cylinder, so that the second motor drives the spiral shaft to smoothly carry out the feeding operation, and the vacuum cleaner can also perform dust collection through the adjustable dust collection head and the fixed dust collection head, so as to maintain the cleanliness of the road surface, prevent the problem of dust in the road surface cleaning process, and maintain a good construction environment;

[0026] 3. The auxiliary device and construction method for dismantling a bridge on a highway can realize the operation of conveying crushed stones upward by driving the screw shaft through the second motor, and the V-shaped structure enclosed by the adjusting scraper and the fixed scraper can realize centralized material guiding, thereby avoiding the accumulation of crushed stones and increasing the burden on the construction vehicle. After the crushed stones enter the recycling box, the first motor can drive the first rotating shaft to drive the grid plate to rotate, so that the grid plate can turn the crushed stones over, so that the crushed stones can be pre-filtered through the upper filter screen for primary filtration and through the lower filter screen for secondary filtration. By turning the crushed stones over, the accumulation of crushed stones can be prevented. The filtering is affected, thereby improving the grading efficiency of the crushed stones, facilitating the subsequent direct recycling, and the spiral shaft feeding process also drives the first gear and the second gear transmission, and the crankshaft drives the slider to reciprocate through the hollow frame, so that the curled brush reciprocates to clean the road surface, thereby improving the road surface cleaning effect, and allowing small crushed stones in the gaps in the road surface to run out, which is convenient for the recovery operation of the vacuum cleaner. In this way, the device not only meets the width of different roads, but also can realize multi-mode cleaning operations, achieving the purpose of integrated multi-functions, thereby reducing the difficulty of subsequent processing and reducing the processing steps.

[0060] In this embodiment: the operation of conveying the crushed stone upward can be realized by driving the screw shaft 2022 through the second motor 2023, and the V-shaped structure enclosed by the adjusting scraper 2052 and the fixed scraper 2051 can realize centralized material guiding, thereby avoiding the accumulation of crushed stone and increasing the burden of the construction vehicle 100. Moreover, after the crushed stone enters the recycling box 2012, the first motor 2011 can drive the first rotating shaft 2014 to drive the grid plate 2013 to rotate, so that the grid plate 2013 can turn the crushed stone, so that the crushed stone can be pre-filtered through the upper filter screen 2015 for primary filtration and through the lower filter screen 2015 for secondary filtration. By turning over the crushed stone, the accumulation of crushed stone can be prevented. The filtering effect can improve the grading efficiency of the crushed stones, which is convenient for subsequent direct recycling. In addition, the feeding process of the spiral shaft 2022 also drives the first gear 2025 and the second gear 2062 to transmit. The crankshaft 2061 drives the slider 2065 to reciprocate through the hollow frame 2064, so that the curled brush 2032 reciprocates to clean the road surface, thereby improving the road surface cleaning effect and allowing small crushed stones in the gaps in the road surface to run out, which is convenient for the recovery operation of the vacuum cleaner 2041. In this way, the device can not only meet the width of different road surfaces, but also realize multi-mode cleaning operations, thereby achieving the purpose of integrated multi-functions, thereby reducing the difficulty of subsequent processing and reducing the processing steps.

[0061] A construction method for removing an auxiliary device for a bridge on a highway comprises the following steps:

[0062] S1. When performing post-removal processing of the road surface, the construction vehicle 100 operates the demolition auxiliary mechanism 200 to travel to the road surface, and then controls the second electric push rod 2054 to retract, and then drives the telescopic frame 2057 to unfold through the sliding sleeve 2055, and the telescopic frame 2057 in turn drives the adjustment scraper 2052 to unfold, so that the support plate 2033 moves with it, and then the reel 2031 releases the rollable brush 2032 to unfold, and at the same time, the support plate 2033 also drives the adjustment dust head 2045 to unfold, so as to meet the road width requirement;

[0063] S2. After adjustment, the construction vehicle 100 moves forward, so that the road gravel is collected by the adjustable scrapers 2052 and the fixed scrapers 2051 on both sides, and is concentrated under the feeding tube 2021. At this time, the second motor 2023 runs to drive the screw shaft 2022 to rotate, and the screw shaft 2022 transports the gravel upward, so that the gravel enters the recycling box 2012 through the telescopic cover 2024, and then the first motor 2011 drives the first rotating shaft 2014 to drive the grid plate 2013 to rotate, so that the gravel passes through the grid plate 2013, and then passes through the upper filter 2015 for primary filtration, and then passes through the lower filter 2015 for secondary filtration, so as to be classified, and finally the fine particles fall into the bottom of the recycling box 2012;

[0064] S3. During the feeding process of the spiral shaft 2022, the spiral shaft 2022 also drives the first gear 2025 and the second gear 2062 to transmit, so that the second gear 2062 drives the crankshaft 2061 to rotate, the crankshaft 2061 drives the hollow frame 2064 to reciprocate, the hollow frame 2064 drives the slider 2065 to reciprocate, and the rollable brush 2032 reciprocates to clean the road surface. During the cleaning process, the vacuum cleaner 2041 performs vacuuming through the fixed vacuum head 2044 and the adjustable vacuum head 2045, and recycles the dust into the recycling box 2012 for collection.
