Description

Technical Field

[0001] The utility model relates to cement paving equipment for engineering construction, belonging to the field of cement paving. Background Art

[0002] Engineering construction is a basic economic activity for the development of human civilization. Since ancient times, engineering construction has been highly valued by all countries.

[0003] As for the cement paving device in engineering construction, during the paving process, cement is first spread on the ground, and then related auxiliary paving mechanical equipment is used. The mechanical equipment will be equipped with a movable roller to level the laid cement.

[0004] However, the length of the rollers of these mechanical equipment is fixed. When paving a cement road that is too wide, it is necessary to push the roller repeatedly to flatten the cement road that is too wide. This results in low flattening efficiency and uneven force on the overall plane of the cement road, which makes it impossible to achieve complete flatness on the overall plane. For some narrower cement roads, when a long roller is used to repeatedly flatten them, since the highest point of the road paving mold is higher than the preset road level, the two ends of the roller will fall on the molds on both sides of the road. For cement that is lower than the height of the mold, the roller cannot be paved, and when the entire fixed width mechanical equipment is subsequently stored, the equipment occupies a large area. Therefore, the present application proposes an engineering construction cement paving equipment with adjustable width. Utility Model Content

Before paving the cement, the surface of the cement is uneven. When the roller rolls on the cement surface, the raised part of the cement surface may cause resistance to the roller. Therefore, the first T-shaped plate 27 and the second T-shaped plate 28 are used to flatten the raised surface of the cement in advance, and then the roller is used for paving to improve the paving efficiency of the cement.

[0035] The first T-shaped plate 27 and the second T-shaped plate 28 are not fixed, and the bottom surfaces of the first T-shaped plate 27 and the second T-shaped plate 28 are parallel to the bottom surface of the second roller, or slightly higher than the bottom surface of the second roller.

[0036] During the specific work, a movable gantry 1 is designed to ensure that the entire equipment can move smoothly. Before the tiling work is carried out, the designed adjustment component is used to adjust the tiling roller component.

[0037] Specific adjustment: the first roller 3 and the third roller 5 on the left and right sides can move closer to or away from each other. The first roller 3 and the third roller 5 are on both sides of the second roller 4, so the first roller 3 and the third roller 5 change the length between the two, plus the fixed length of the second roller 4 itself, so as to adjust the length of the first roller 3, the third roller 5 and the second roller 4 as a whole to adapt to the width of the road surface. The roller material of this application is steel.

[0038] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
