The falling prevention device has a simple, compact and reasonable structure, and can prevent a falling object or a person from falling into the inspection well, so that the safety of the inspection well is improved; the falling prevention device is convenient to repair, maintain and mount and can be widely applied to various inspection wells; anchor bolts or bulges which are raised inwards are not arranged, so that inspectors can conveniently go in and out of the inspection well without being affected.
Description
Technical field
The utility model relates to a kind of municipal manhole anti-drop device, and a kind of anti-drop device of the drainage inspection well with anti-drop function of easy accessibility, belong to the urban operating mechanism technical field specifically.
Background technology
Current GB drainage inspection well structure is pit shaft, well lid and well holder structure, and 2 ~ 6 meters of municipal manhole buried depths, isolated by well lid.Once but manhole cover damage or loss, outside drainage inspection well will be directly exposed to, the darker well body of buried depth just becomes the road trap, is easy to cause casualties, and has caused at present a lot of personnel to fall the missing death incident of well.
A kind of municipal manhole anti-drop device of Chinese patent " CN202881977U ", comprise that moving door, gate seat, slideway form, and moving door is opened by slideway, plays anti-fall effect when closed.Although this device has solved the anti-fall problem of manhole, gate seat construction maintenance difficulty need to be set at pit shaft middle part, once and take outside well lid the road structure layer and damage and must excavate maintenance; Complicated in mechanical structure on the other hand, can't be in the aboveground enforcement of PE.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of municipal manhole anti-drop device simple in structure is provided, easy accessibility, and easy access is safeguarded, has been improved safety simultaneously.
The technical scheme provided according to the utility model, municipal manhole anti-drop device comprises mounting bracket and anti-fall web plate, it is characterized in that: the mounting bracket inner ring is provided with supporting station, and anti-fall web plate is positioned on supporting station.Described anti-fall web plate comprises two symmetrically arranged anti-fall frameworks and be positioned at two safety nets on anti-fall framework, and the end of two anti-fall frameworks connects supporting station by bearing pin, and anti-fall framework realizes upwards overturning by bearing pin.
Further, anti-fall framework is the semicircle annular.
Further, the mounting bracket inwall is provided with a plurality of equally distributed fixing holes, connects a crab-bolt in each fixing hole.
Further, two anti-fall frameworks are provided with a plurality of ropes hole, and the logical rope through of safety net is fixed on two anti-fall frameworks.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, and after the manhole well lid is lost or damaged, the anti-fall web plate of lower floor can prevent that falling stop thing or personnel fall down manhole, improves the safety of manhole; Anti-fall web plate is connected with mounting bracket by bearing pin, launches or the anti-fall framework of overturning can be opened or closed anti-fall web plate easily, and easy access is safeguarded; Anti-drop device is bolted at shaft in wall, easy for installation, can be widely used in various manholes, and whole inwardly protruded crab-bolt or the projection of not arranging, and can not pass in and out manhole to the inspection personnel and impact.

Description of reference numerals: 1-mounting bracket, the anti-fall web plate of 2-, the anti-fall framework of 3-, 4-safety net, 5-fixing hole, 6-crab-bolt, 7-bearing pin, 8-supporting station.
The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 3, the utility model mainly comprises mounting bracket 1 and anti-fall web plate 2, and mounting bracket 1 inner ring is provided with supporting station 8, and anti-fall web plate 2 is positioned on supporting station 8.
Described anti-fall web plate 2 comprises that the anti-fall framework 3 of two symmetrically arranged semicircle annulars and the end that is positioned at two 4, two anti-fall frameworks 3 of safety net on anti-fall framework 3 connect supporting stations 8 by bearing pin 7.Anti-fall framework 3 realizes upwards upset by bearing pin 7.Described two anti-fall frameworks 3 are provided with a plurality of ropes hole, and the logical rope through of safety net 4 is fixed on two anti-fall frameworks 3.
Described mounting bracket 1 inwall is provided with a plurality of equally distributed fixing holes 5, connects a crab-bolt 6 in each fixing hole 5, and mounting bracket 1 is fixed on the manhole shaft inwall by crab-bolt 6.The diameter of described mounting bracket 1 is slightly less than the diameter of pit shaft, and mounting bracket 1 one sides are close to shaft in wall.
Described mounting bracket 1 and anti-fall framework 3 adopt the material that ductile iron, plastic-steel or steel equal strength are enough to make, and take anti-corrosion measure.
Described safety net 4 adopts the nylon rope material to be woven into net structure, and the mesh size is not more than 10cm and is advisable.
Operating principle of the present invention is: mounting bracket 1 is fixed on when flat on the shaft in wall of twenty or thirty centimetre under well lid, and anti-fall web plate 2 is positioned on mounting bracket 1, and the anti-fall framework 3 of two semi-annular shapes is launched to form closed circle, and safety net 4 is opened.When well lid is lost or damage, anti-fall web plate 2 prevents from the pedestrian or falls thing falling in manhole.When pipeline needs repair and maintenance, the anti-fall framework 3 of upwards overturning, safety net 4 closures, the shaft in wall access path is opened; After having overhauled, anti-fall framework 3 upsets are resetted and get final product.Due to anti-fall framework 3, via on bearing pin 7 connection supports 1, open flexibly and easily, and whole device do not have crab-bolt or thrust, can not look into and bring inconvenience the health check-up of turnover well.
