Description

Can regulate the mashed end hole lid of anti-sinking automatically

Technical field

The utility model belongs to highway well lid field, relates to a kind of can the adjusting automatically and prevents from and the well lid on mashed limit.

Background technology

At present, the traditional well lid that uses on the highway, because its walling crib structure design is unreasonable, exist serious sinking and mashed limit problem, the general new highway of repairing is through the backing of various haulage vehicles, the mashed limit of sinking and road surface phenomenon in various degree will appear in well lid behind the some months, promptly influences the planeness of highway, brings great hidden danger to traffic safety again; For addressing this problem, unit in charge of construction generally adopts and manually chisels the method that study for a second time courses one has flunked on the road surface, has not only wasted great amount of manpower, financial resources, and can not fundamentally thoroughly solve.

Summary of the invention

The purpose of this utility model is to solve above-mentioned prior art problem and a kind of mashed end hole lid of anti-sinking of can regulating automatically is provided, and is easy to use, safe and reliable, can prevent effectively that well lid from sinking and mashed limit, road surface, economical and practical.

The technical solution adopted in the utility model: a kind of mashed end hole of anti-sinking of can regulating automatically covers, comprise cement circle, walling crib, loam cake, the cement circle is arranged on the well body, walling crib is provided with loam cake, be provided with adjustment seat in the slideway of described cement circle, walling crib is seated on the adjustment seat, and walling crib connects with adjustment seat by extension spring.

Described walling crib bottom surface is by being evenly distributed in slide block, and the slide block bottom surface is the inclined plane, matches with the inclined plane, chute bottom surface, center of adjustment seat.

The utility model novel structure, walling crib is reasonable in design, can regulate automatically between walling crib and the well body and produce the gap, effectively solves the mashed limit of well lid sinking and road surface problem, and is easy to use, safe and reliable, do not need to repair, and can save a large amount of manpowers, financial resources, economical and practical.
