In view of the above, an object of the present utility model is to provide a roadbed leveling assistance device.
In order to achieve the above purpose, the following technical scheme is adopted:
the roadbed leveling auxiliary device comprises a square cross bar with two ends lapped on steps on two sides of a roadbed, wherein 2-3 groups of adjusting components are arranged on the cross bar in a penetrating way;
the adjusting assembly comprises a sliding sleeve, a sleeve and a screw rod, wherein the sliding sleeve is arranged on the cross rod in a penetrating mode, the sleeve is fixedly arranged on one side of the sliding sleeve, screw sleeves are arranged at the upper end and the lower end of the sleeve, the screw rod is connected to the sleeve through threads, and cotton ropes are connected between the lower ends of 2-3 screw rods.
As a further improvement of the utility model, the outer wall of the sliding sleeve is provided with a bolt which is propped against the cross rod to play a role of fixing and limiting.
As a further improvement of the utility model, the outer wall of the screw rod is axially provided with a flat cutting section for marking scales.
As a further improvement of the utility model, the lower end of the screw rod is provided with a groove for connecting cotton ropes.
As a further improvement of the utility model, the upper end of the screw rod is provided with a handle which is used for facilitating rotation adjustment.
The beneficial effects of the utility model are as follows:
the utility model has simple structure and ingenious design, can accurately ensure the straightness of cotton wires by adjusting the downward extension of the screw rod, and can well control the downward extension length, assist in roadbed construction, ensure the flatness and realize high-quality roadbed.
