In order to achieve the purpose, the utility model adopts the technical scheme that: a pull rod device for smoothing the surface of a duct piece comprises a smoothing frame with a U-shaped section, handles respectively arranged at two ends of the smoothing frame, and at least two vibrating motors which are symmetrically arranged at the top of the smoothing frame; the smoothing frame is made of C-shaped steel.

Preferably, the smoothing frame has the length of 160mm, the width of 60mm, the height of 20mm and the thickness of 3 mm.

Preferably, two sides of the upper end of the flattening frame are respectively provided with inward bent flanges; the two turning edges are provided with long sliding grooves which are arranged along the length direction of the floating frame; two ends of the vibration motor are respectively arranged on the two turned edges, and two through holes corresponding to the two strip sliding grooves are respectively arranged on two sides of the base of the vibration motor; the through hole and the long sliding groove are connected through a bolt assembly.

Preferably, the handle comprises two connecting rods which are arranged in parallel and one end of each connecting rod is connected with the end part of the floating frame, and a holding rod which is respectively connected with the two connecting rods.

Preferably, the connecting rod is obliquely arranged, and the inclination angle is 30-45 degrees.

Preferably, the connecting rods are all welded with the ends of the floating frame.

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. according to the utility model, the original 10# channel steel is replaced by 12# C-shaped steel, so that the mass of a single 12# C-shaped steel is only 10.6kg, the weight is greatly reduced, the operation of workers is lighter and quicker, the labor intensity is reduced, and the working efficiency is greatly improved;

2. the C-shaped steel is driven to vibrate by the vibration motor, so that the effects of trowelling and compacting concrete can be quickly achieved, and the surface of the concrete can be more compact.
