Abstract
The utility model relates to a be located screw-in inspection shaft lid anti-falling device of inspection shaft lid lower part position comprises drop prevention dish and composite support frame, and drop prevention dish is with the rotatory joint of composite support frame, and upper portion is adding the inspection shaft well lid, when taking place that the well lid is stolen or defective, can ensure the safety of pedestrian, vehicle, when sewage from the inspection shaft is overflow, can prevent effectively that composite inspection shaft lid is not washed out by the water-washed, and this utility model discloses device simple to operate moreover, it is easy to dismantle, can use on circular inspection shaft on a large scale.
Description
Technical field
The utility model relates to a kind of inspection shaft lid falling proof device, but relates in particular to a kind of screw-in inspection shaft lid falling proof device that is positioned at inspection shaft lid lower position.
Background technology
Quick propelling along with the urbanization construction, the extension of road road network, supporting with it sewage network and sewage inspection shaft constantly increase, sewage inspection shaft particularly since bury darker, and often there is toxic and harmful, in recent years, stolen or damaged because of road cellar well lid, cause car to turn over that the people hinders even the security incident of engulfing life constantly is reported in media, how to avoid the generation of such accident effectively, the safety of guaranteeing pedestrian, vehicle is many problems of going into to study.Inspection shaft lid in the past mostly is cast iron or composite material is made, and the inspection shaft lid of cast iron materials is easy to stolen, and the inspection shaft lid of composite material is because the characteristics of its material are easy to breakage, and above situation makes the inspection shaft mouth expose, and is easy to cause the generation of road accident.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, a kind of inspection shaft lid falling proof device is proposed, thereby prevent well that the inspection shaft mouth does not expose under the stolen or damaged situation of inspection shaft lid, taken precautions against the generation that pedestrian, vehicle fell similar accidents such as inspection shaft.
The utility model achieves the goal by following measure:
But screw-in inspection shaft lid falling proof device, form by dropproof dish and composite supporting frame, dropproof dish is the circular disk structures of regular three teeth, wherein containing several circular ports leaks, the back side is regular netted train of thought supporting network, combine together with dropproof dish, dropproof dish outer is higher than whole card, can make rainwater well fall into inspection shaft from leak in the hole, the composite supporting frame is irregular rectangular configuration, is divided into two structure divisions up and down, superstructure contains fluted being used for dropproof web along combination, substructure contains circular hole, and this circular hole is used for inspection shaft borehole wall expansion bolt fixed engagement, and the upper surface of composite supporting frame is used to put puts Cover of inspection well.
The quantity of described composite supporting frame is three, because the inspection shaft wall is a circular configuration, so the composite supporting frame is parallel to each other with 2 positions of inspection shaft borehole wall circumference, 6 positions and 10 positions respectively and is mounted on the inspection shaft borehole wall with expansion bolt, fixed point is positioned at overhead on the inspection shaft borehole wall about 10cm.
Described dropproof dish is the circular disk structures of regular three teeth, and the circular disk structure of its three special teeth is used for preventing dropproof dish accidental fall with composite supporting frame rotation joint.
The beneficial effects of the utility model are when the generation well lid is stolen or damaged, can ensure the safety of pedestrian, vehicle, when sewage during, can prevent effectively that composite manhole cover from not washed open by water, and this new device is easy for installation from the inspection shaft spill-over, dismounting can be used on circular inspection shaft easily on a large scale.
Description of drawings
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model structure schematic diagram.
Fig. 3 is the utility model cross-sectional view.
Among the figure 1, the inspection shaft borehole wall, 2, the composite supporting frame, 3, dropproof dish, 4, Cover of inspection well, 5, expansion bolt, 6, the hole leaks, 7, netted train of thought supporting network.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown specific embodiment of the utility model in the accompanying drawing.
But screw-in inspection shaft lid falling proof device, form by dropproof dish (3) and composite supporting frame (2), dropproof dish (3) is the circular disk structures of regular three teeth, wherein contain several circular ports and leak (6), the back side is regular netted train of thought supporting network (7), melt with dropproof dish and to be body, dropproof dish outer is higher than whole card, rainwater is well leaked (6) from the hole fall into inspection shaft, composite supporting frame (2) is irregular rectangular configuration, be divided into two structure divisions up and down, superstructure contains fluted being used for dropproof dish (3) edge combination, substructure contains circular hole, and this circular hole is used for the inspection shaft borehole wall (1) with expansion bolt (5) fixed engagement, and the upper surface of composite supporting frame (2) is used to put puts Cover of inspection well (4).
The quantity of described composite supporting frame (2) is three, because the inspection shaft borehole wall (1) is a circular configuration, so composite supporting frame respectively (2) is parallel to each other with 2 positions in the inspection shaft borehole wall (1) net week, 6 positions and 10 positions and is mounted on the inspection shaft borehole wall with expansion bolt (5), fixed point is positioned at overhead on the inspection shaft borehole wall (1) about 10cm.
Described dropproof dish (3) is the circular disk structures of regular three teeth, and the circular disk structure of its three special teeth is used for preventing dropproof dish accidental fall with composite supporting frame (2) rotation joint.
During use, earlier that composite supporting frame (2) is fixing with setscrew (5) according to three horizontal equidistant points positions of the inspection shaft borehole wall (1) circumference, again in the bayonet socket with dropproof dish (3) parallel screw-in composite supporting frame (2), because the special construction of dropproof dish (3), at first the minor face of diameter is put on composite supporting frame (2) bayonet socket, horizontal direction is rotated again, until dropproof dish (3) fully and composite supporting frame (2) bayonet socket stuck, again Cover of inspection well (4) is covered at composite supporting frame (2) and go up and embed the inspection shaft borehole wall (1), support by composite supporting frame (2).
The beneficial effects of the utility model are when the generation well lid is stolen or damaged, can ensure row The safety of people, vehicle when sewage during from the inspection shaft spill-over, can effectively prevent compound Cover of inspection well (4) Do not washed open by water, and this new device is easy for installation, dismounting can be used easily on a large scale On circular manhole.
