Abstract
The utility model provides an anti-dropping cover for an inspection well. The anti-dropping cover comprises an anti-dropping plate and support frames, wherein the support frames are fixed at the opening of the inspection well; the anti-dropping plate is clamped in the support frames to seal the opening of the inspection well; each support frame comprises a fixed block and a movable block, the fixed block is arranged at the opening of the inspection well via a fixed connecting part, the movable block is connected with the fixed block via a detachable connecting part, a clamping opening is formed between the movable block and the fixed block, and the edge of the anti-dropping plate extends into the clamping opening; a mounting hole is formed in the bottom of each fixed block, and a fixed connecting part penetrates through the mounting hole and enabling the fixed block to be arranged at the opening of the inspection well; a though hole is formed in each movable block, a mounting groove is formed in the top of the fixed block, an anti-theft bolt penetrates through the through hole and extends into the mounting groove to connect the movable block with the fixed block. The anti-dropping cover is fixed at the opening of the inspection well, the anti-dropping cover is covered with a common inspection well cover, when the inspection well cover is defective or the underground water overflows, the anti-dropping cover plays a role of blocking, so that the safety of a road is ensured, and the anti-dropping cover can be changed modified in the conventional inspection well.
Description
Technical field
The utility model relates to manhole cover, relates in particular to the anti-fall lid of a kind of manhole.
Background technology
Manhole is to lead to the go out population of underground installation as facilities such as tap water, draining, telecommunications, electric power, combustion gas, heating power, fire-fighting, sanitation of environment, manhole cover is to check the openable closure of well head, bearing and well lid, consisting of, is requisite facility in urban construction.Along with developing rapidly of urban modernization, the day by day perfect and expansion of all kinds of urban operating mechanism scales and function, the quantity of all kinds of manholes is also sharply increasing.Manhole cover is the requisite part of manhole, and it can not only guarantee the coast is clear and traffic safety, is also embodying to a certain extent city image.The metal well lid is generally casting iron well lid and ductile cast iron manhole cover, is characterized in that cost is higher, theftproof is poor, but because its bearing capacity is high, the shock resistance fatigue resistance is good, and attractive and durable, meets the requirement of urban modernization image, thereby use amount is still maximum.The material of nonmetal manhole cover is generally concrete, steel fibrous concrete and composite material etc., is characterized in that cost is low, theftproof is high, but weight is large, poor, the easy breakage of shock resistance fatigue resistance, the life-span is short, image is poor and open inconvenient.In the situation that well lid displacement, well head directly exposes, and can cause the hidden loyalty of safety to pedestrian and vehicle, and for example well lid is stolen or damaged, and when flood or sewer blockage occur, current are by well lid jack-up.Therefore, be necessary the structure of well lid is improved, prevent from causing the hidden loyalty of road safety after the well lid displacement.
The utility model content
The purpose of this utility model is to provide the anti-fall lid of a kind of manhole, avoids that well lid is damaged to be impacted road safety.
The utility model is that the technical scheme that its technical problem of solution adopts is,
The anti-fall lid of a kind of manhole, comprise anti-fall plate and bracing frame, and bracing frame is with scheduling the manhole opening part, and anti-fall board is connected in bracing frame, and the manhole opening is sealed;
Bracing frame comprises fixed block and movable block, and fixed block is by being located at the manhole opening part with determining connector, and movable block is connected with fixed block by removable connector, between movable block and fixed block, has card interface, and the edge of anti-fall plate stretches in this card interface;
The fixed block bottom has installing hole, by fixed connecting piece, through this installing hole, fixed block is located to the manhole opening part;
Have through hole in movable block, the fixed block top has mounting groove, by anti-theft bolt, is passed through hole and is stretched in mounting groove, and movable block is connected with fixed block;
Have card article on card interface, anti-fall panel edges has rib, and the edge of anti-fall plate props up card article by rib after stretching into card interface, prevents that anti-fall panel edges from deviating from from card interface.
During use, first at borehole wall place, lower than the Manhole covers pedestal, with the upper/lower positions addressing, punch, and pre-buried fixed block, anti-fall plate is placed on fixed block, use special tool to tighten anti-theft bolt, movable block is connected with fixed block, anti-fall plate holder is loaded between movable block and fixed block, finally add manhole cover and get final product.
The utility model has the advantage of, this anti-fall lid is fixed in to the manhole opening part, and conventional well lid is covered in the anti-fall side of covering, when well lid is damaged, anti-fall lid can play the barrier effect, prevents that the pedestrian from dropping, when underground current spill-over, anti-fall lid is stopped current, prevent that well lid is rushed to open, thus ensure road safety, and it is simple in structure, easy accessibility, and easily in existing manhole, reequiped.
The accompanying drawing explanation
Fig. 1 is the structural representation of the anti-fall lid of manhole that the utility model proposes;
Fig. 2 is the structural representation of bracing frame.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1 and Figure 2, the anti-fall lid of the manhole the utility model proposes comprises anti-fall plate 1 and bracing frame 2, and bracing frame 2 is fixed in the manhole opening part, and anti-fall plate 1 is connected in bracing frame 2, and the manhole opening is sealed; Bracing frame 2 comprises fixed block 3 and movable block 4, be located at the manhole opening part with determining piece 3 by fixed connecting piece, movable block 4 is connected with fixed block 3 by removable connector, between movable block 4 and fixed block 3, has card interface 5, and the edge of anti-fall plate 1 stretches in this card interface 5; Fixed block 3 bottoms have installing hole 6, by fixed connecting piece, through this installing hole 6, fixed block 3 are located to the manhole opening part; There is through hole in movable block 4, with determining piece 3 tops, there is mounting groove 7, by anti-theft bolt 8, pass through hole and stretch in mounting groove 7, movable block 4 is connected with fixed block 3; Have card article 9 on card interface 5, anti-fall plate 1 edge has rib 10, and the edge of anti-fall plate 1 props up card article 9 by rib 10 after stretching into card interface 5, prevents that anti-fall plate 1 edge from deviating from from card interface 5.
During use, first at borehole wall place, lower than the Manhole covers pedestal, with the upper/lower positions addressing, punch, and pre-buried fixed block, anti-fall plate is placed on fixed block, use special tool to tighten anti-theft bolt, movable block is connected with fixed block, anti-fall plate holder is loaded on to movable block and, with determining between piece, finally adds manhole cover and get final product.
