Abstract
The utility model relates to a kind of inspection shaft protected apron.The protected apron that object is to provide should have enough intensity thus the weight of carrying human body, thus avoids pedestrian to fall, protection personal safety, and has the feature of good looking appearance.Technical scheme is: a kind of inspection shaft protected apron, is characterized in that: comprise a skeleton, and the outer of skeleton is provided with the projection that a circle is arranged in the form of a ring, wherein several projections offers the through hole for locating thus forms locating convex block.
Description
Technical field
The utility model relates to inspection shaft technical field, specifically the protected apron of inspection shaft.
Background technology
Day by day perfect along with municipal pipeline, communication network and electric power networks, the inspection shaft on road gets more and more.Existing inspection shaft generally adopts inspection well cover to carry out capping to it, after inspection well cover is opened or damages, there is holdee and falls into danger wherein, for this situation, general way arranges protective screening below inspection well cover, and the defect of protective screening is that profile is attractive in appearance not, waits to solve.
Utility model content
Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned background technology; there is provided a kind of inspection shaft protected apron, this protected apron should have enough intensity thus the weight of carrying human body, thus avoids pedestrian to fall; protection personal safety, and there is the feature of good looking appearance.
The utility model have employed following technical scheme: a kind of inspection shaft protected apron, is characterized in that: comprise a skeleton, and the outer of skeleton is provided with the projection that a circle is arranged in the form of a ring, wherein several projections offers the through hole for locating thus forms locating convex block.
As preferably, described skeleton comprises housing and is arranged on the grid in housing, and grid and housing and projection adopt integrally moulded.
As preferably, described housing is polygon, and the outside on every bar limit of housing is equipped with several projections.
As preferably, described grid is made up of the multiple ribs arranged in length and breadth, and at least two ribs through housing center are main muscle, and the two ends of each main muscle are equipped with a described locating convex block, and locating convex block offer described through hole.
As preferably, the position between described through hole with locating convex block edge coordinates with a U-lag, and the bottom of U-lag is positioned on inspection shaft wall by cross bar, and the top of U-lag is provided with a latch.
As preferably, described projection is trapezoidal projection or triangular bump.
As preferably, described projection offers loss of weight through hole.
The beneficial effects of the utility model are: the utility model coordinates projection by polygonal housing, form the circle adapted with inspection shaft inwall, and protected apron supports and locates by recycling U-lag, install simple; And integrated skeleton construction good looking appearance, can effectively support human body, protection personal safety, reliability is high, projection offers loss of weight through hole, can reduce weight of the present utility model and consumptive material, reduces cost of production.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the mounting structure schematic diagram of locating convex block and U-lag.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of inspection shaft protected apron described in the utility model, comprise a skeleton, the outer of skeleton is provided with the projection 2 that a circle is arranged in the form of a ring, projection 2 offers loss of weight through hole 2-1, the diameter of the outer end of this circle projection and the internal diameter of inspection shaft 9 adapt, and wherein several projections offer the through hole 6 for locating thus form locating convex block 5.
Described skeleton comprises housing 1 and is arranged on the grid 3 in housing, and grid and housing and projection adopt integrally moulded, and usually, the thickness of skeleton, projection and platform is equal, and recommendation thickness is 2-4cm.Described housing is polygon (being generally hexagon or octagon), and the outside on every bar limit of housing is equipped with projection described in several (can arrange 3-4 projection as required, each bump size is different).
Described grid is made up of (rib quantity is determined as required) the multiple ribs arranged in length and breadth, at least two ribs through housing center are main muscle 4 (diameter of main muscle is greater than all the other ribs), the two ends of each main muscle are equipped with a described locating convex block, and locating convex block offer described through hole.As shown in Figure 2, for protected apron is positioned in inspection shaft, position 5-1 between described through hole and the outer side edges edge of locating convex block coordinates with a U-lag 7 (both sides of U-lag lay respectively at through hole and outer side edges edge), the bottom of U-lag embeds in the concrete inner wall of inspection shaft by cross bar 8, the both sides of U-lag upper end are connected by a latch 10, and described projection is trapezoidal projection or triangular bump (being triangle in Fig. 1).Due in work progress, the inwall of inspection shaft is sometimes not exclusively rounded, therefore the external diameter of described locating convex block is than the large 0.5 ~ 1.2cm of the external diameter of all the other projections (distance at the outer end of external diameter specific bit projection, the outer end of projection and inspection shaft protected apron center), can cut the outer end of locating convex block during construction, grinding process, make it adapt to the inwall of inspection shaft.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
