TECHNICAL FIELD

[0001] The utility model relates to road construction field, more specifically, relate to a kind of road pavement trowelling auxiliary frame. BACKGROUND

[0002] Cement pavement trowelling is an important procedure in road construction. After the completion of cement pavement laying, trowelling operation is carried out when it has not completely solidified. Construction personnel usually use professional trowelling tools, such as trowelling machine, iron trowel, etc. First, trowelling can make the pavement more flat. Through repeated scraping and trowelling, defects such as unevenness, cracks and pores on the cement pavement are eliminated, providing a smooth driving surface for pedestrians and vehicles. This not only improves the comfort and safety of driving, but also reduces the wear and damage of vehicles to the pavement. Secondly, trowelling helps to improve the compactness of the pavement. During trowelling, construction personnel will compact the cement, making the cement particles more closely combined, thereby enhancing the strength and durability of the pavement. Compact pavement can better resist the penetration and erosion of rainwater, reducing the possibility of pavement damage.

[0003] When trowelling the cement pavement, a suspension ladder is usually needed, which is erected directly above the road, placed flat on the cement pavement, and the worker stands on the suspension ladder to trowel the pavement with a trowel. The suspension ladder has the following disadvantages when in use: the bottom side of the suspension ladder presses on the pavement, causing damage to the pavement; the personnel need to move on the suspension ladder to trowel different positions of the cement pavement, which is not stable enough; the suspension ladder needs to be frequently moved and replaced, which is not flexible enough.

[0005] To solve the above problems, the utility model adopts the following technical scheme.

[0006] A road pavement trowelling auxiliary frame, comprising a portal frame and a trowelling cage, wherein the top of the portal frame is welded with a top cross beam, the top of the trowelling cage is provided with a U-shaped plug, the U-shaped plug is inserted and installed on the outer side of the top cross beam, and the top of the U-shaped plug is installed with a moving wheel, a rotating shaft is installed between the moving wheel and the U-shaped plug, and the moving wheel rolls on the upper surface of the top cross beam, and the bottom of the trowelling cage is welded with a bottom plate.

[0007] Further, the moving wheel and the U-shaped plug are connected through the rotating shaft, and the outer side of one of the rotating shafts is nested with a gear.

[0008] Further, the outer side of the gear is nested with a belt, and the belt and the gear are in meshing connection.

[0009] Further, the bottom of the portal frame is nested with a support frame, and the inner side of the portal frame is welded with a horizontal rod A, and the center of the horizontal rod A is movably installed with a rotating disc.

[0010] Further, the bottom of the support frame is installed with a roller, and the inner side of the support frame is welded with a horizontal rod B, and the center of the horizontal rod B is welded with a screw rod, the screw rod penetrates through the center of the rotating disc, and the screw rod and the rotating disc are in threaded screwing connection.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The construction mode of the suspension ladder is cancelled, the portal frame is adopted, the trowelling cage capable of moving horizontally is arranged in the inner side of the portal frame, the height of the portal frame is adjustable, the trowelling cage is suspended in the air and does not press the concrete pavement to be trowelled, the horizontal movement of the trowelling cage is controlled by workers by pulling the belt, the movement is stable and smooth, the support frame installed at the bottom of the portal frame is installed with the roller, the portal frame can be integrally moved, and the operation is flexible and convenient.
