Description

The anti-fall well lid of a kind of inspection shaft and Wrench for opening

Technical field

The utility model relates to a kind of inspection shaft falling proof device, especially relates to a kind of well lid with anti-drop function, is used for Urban Underground plumbing, communication cable, power cable pipe inspection well head, prevents that pedestrian or object from crashing in well from well head; The utility model also relates to a kind of Wrench for opening of drop device.

Background technology

Along with the quick propelling of Process of Urbanization Construction, underground water supply and drainage, communication cable, power cable number of tubes constantly increase, and in the turning of pipe network, the place such as is fallen at by branch, and for ease of checking or dredging, standing have manhole, has another name called inspection shaft.At present, inspection well cover mostly is cast iron or composite material is made, and the inspection well cover of cast iron materials is easy to stolen, and the inspection well cover of composite material is because the characteristics of its material are easy to breakage, and above situation makes catch pit port expose, and is easy to cause the generation of road accident.In addition, when meeting continuous heavy rain when causing the urban road accumulated water, the normal custom of people is opened well lid in order to accelerate draining, and the well head that loses well lid ground pedestrian or object occurs often crashes into accident in well.In recent years, steal or damaged because of the road cellar well cover, cause car to turn over people's wound and even engulf the security incident of life and happen occasionally, how effectively to avoid the generation of such accident, the safety of guaranteeing pedestrian, vehicle is urgent problem.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, proposes a kind of inspection shaft fall arrest well lid, thereby prevents well in the stolen or damaged situation of inspection well cover, takes precautions against the accident that pedestrian, vehicle fall in well and occurs.

In order to solve the problems of the technologies described above, the inspection shaft fall arrest well lid that the utility model provides has the well seat; Be installed on the cover plate at described well seat top; Anti-fall grid; Fixing chuck plate, described anti-fall grid has three mounting rods at least, the bottom of described well seat has quantity and is not less than the quantity of described mounting rod for the deck that described mounting rod is installed, the locating groove that described deck has the guiding draw-in groove and is communicated with described guiding draw-in groove, described mounting rod is in the described locating groove of described guiding draw-in groove turnover, the bottom of described guiding draw-in groove has screwed hole, described fixing chuck plate removably connects by special shaped screw bolt and described screwed hole, after connection with described anti-fall grid locking.

Further, as one of preferred version of the present utility model, the head of the special shaped screw bolt of the anti-fall well lid of described inspection shaft is circular, and head end has the circular open hole that is the equilateral triangle layout.

The utility model also provides a kind of Wrench for opening be used to opening aforementioned preferred version special shaped screw bolt, described Wrench for opening comprises T-shaped handle, be positioned at described T-shaped handle one end cylinder, be fixed on described cylinder away from the latch of handle end, the position of described latch coordinates with the position of described open hole.

The beneficial effect that the utility model brings: the inspection shaft fall arrest well lid that the utility model provides, when the Cover of inspection well plate was stolen or damaged, anti-fall grid can stop ground pedestrian or object to crash in well, guarantees the safety of pedestrian, vehicle.Have and install rapidly, the advantage that supporting capacity is high, when material was ductile iron, the load of the anti-fall grid of ductile iron can be over 3 tons.
