Abstract
The invention discloses an inspection shaft falling-prevention alarming and protecting device which comprises an anti-falling mesh fixedly connected onto the bottom or the inner wall of an outer ring of an inspection shaft, a central hole is arranged in the anti-falling mesh, a column penetrates through the central hole, a pressure spring is sleeved on the surface of the column, two right-triangular elastic supports which are arranged in a perpendicularly crossing mode are fixedly installed at the top of the column, a torsion spring is arranged on an included angle of the right-angle bottom edge and the inclined edge of each elastic support, a light-reflecting alarming plate is arranged on each elastic support, and the pressure spring is arranged between the top of the column and the anti-falling mesh. When an inspection well cover is damaged, stolen or lost due to backwash, the inspection shaft falling-prevention alarming and protecting device can extend upwards to get out of a shaft opening automatically so as to remind passengers and vehicles, the anti-falling mesh is fixedly connected onto the bottom or the inner wall of the outer ring of the inspection shaft as the final safety barrier for passengers, the strong protection effect on the passengers falling into the shaft accidently can be achieved, and people cannot be damaged even falling into the shaft carelessly.
Description
Technical field
The present invention relates to the ancillary facility of inspection shaft in road, particularly catch pit port open after a kind of anti-falling warning protective device.
Background technology
Existing inspection well cover is all do not warn and defencive function; once inspection well cover is stolen, damage or opened by borehole pressure recoil after will bring great danger to pedestrian and vehicle; pendant well event happens occasionally; well depth is all more than 4 meters; social harm is very large; citizen have strong complaints to this, not yet have desirable effective solution so far.
Summary of the invention
The object of the present invention is to provide a kind of inspection shaft anti-falling warning protective device, damage or can automatically open while losing warning mark at inspection well cover and remind pedestrian and vehicle, for prompting inefficacy those who fall well of slipping, there is anti-injury protection function simultaneously.
The object of the invention is to be achieved by the following technical programs; a kind of inspection shaft anti-falling warning protective device; it is characterized in that; comprise with bottom inspection shaft outer ring or the anti-drop net that is fixedly connected with of inwall; anti-drop net offers centre bore, and centre bore, through a root post, the cylinder of column is set with a stage clip; the light reflecting caution board of the top fixed installation elastic telescopic of column, described stage clip is located between column top and anti-drop net.
Further, the top of described column is provided with the platform between restriction stage clip breathing zone, and described platform fixedly mounts the elastic support that two square crossings are arranged, described light reflecting caution board is arranged on elastic support.
Further, described elastic support is triangle or quadrangle elastic support, and the angle of elastic support base and its adjacent side is provided with torsion spring.
Beneficial effect: the present invention inspection well cover damage or stolen, lost by recoil while automatically can protrude upward well head and open warning mark and remind pedestrian and vehicle; bottom inspection shaft outer ring or the anti-drop net that is fixedly connected with of inwall; as last one safety curtain of pedestrian; pedestrian for pendant well of slipping still plays strong protective effect, also can not cause serious injury even if accidentally crash in well.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the state diagram that this device is arranged on inspection well cover;
Fig. 3 is the state diagram after this device is opened.
Detailed description of the invention
As Fig. 1, 2, shown in 3, a kind of inspection shaft anti-falling warning protective device provided by the present invention, comprise with bottom inspection shaft outer ring 10 or the anti-drop net 1 that is fixedly connected with of inwall, anti-drop net adopts expanded metal lath or the gauze wire cloth of higher-strength, the excircle of anti-drop net 1 is provided with otic placode 8, otic placode 8 has bolt hole, anti-drop net 1 is fixed on the inwall of inspection shaft outer ring 10 through the bolt hole on otic placode 8 by bolt 9, also anti-drop net can be fixedly mounted on the bottom of inspection shaft outer ring by direct bolt, anti-drop net 1 offers centre bore, centre bore is through a root post 2, the cylinder of column 2 is set with a stage clip 4, the top of column 2 is provided with the platform 3 between restriction stage clip breathing zone, platform 3 fixedly mounts the elastic support 5 that two square crossings are arranged, elastic support 5 is installed light reflecting caution board 7, ensure that four direction can see light reflecting caution board, elastic support 5 adopts right-angled triangle elastic support, the angle of its base, right angle and hypotenuse is provided with torsion spring 6, stage clip 4 is located between column top platform 3 and anti-drop net 1.As shown in Figure 2, when inspection well cover is intact, this device is compressed in the inspection shaft outer ring 10 of inner cap less than 11 under inner cap 11 Action of Gravity Field; As shown in Figure 3, when inspection shaft inner cap damage or stolen, lost by recoil after, this device loses the compressing of original inner cap gravity, and light reflecting caution board 7 automatically upwards opens ejection catch pit port, to reach the effect of safety instruction under the effect of stage clip 4 and elastic support 5.Anti-drop net, as last one safety curtain of pedestrian, even if accidentally fall on anti-drop net, is also unlikely to cause serious injury.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention; Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belongs in the scope of technical solution of the present invention protection.
