Description
Technical field
The utility model relates to a kind of inspection shaft lid, relates in particular to a kind of Safety manhole cover with protective screening.
Background technology
Along with economic, social high speed development, row's water system in city, city, various countries, electric supply system, communications network system and fuel feeding heating system etc. all or are progressively carried from underground passage.Linking highway section or hinge for these systems divide flowpath segment, and the easiest highway section of breaking down needs often maintenance often.Safeguard and maintenance that for the ease of people some maintenance inspection shafts usually can be set in these highway sections, and therefore, the use of inspection shaft lid also becomes more and more.Existing inspection shaft lid mainly contains cast iron inspection shaft lid, compound resin inspection shaft lid and cement and builds the inspection shaft lid, and these inspection shafts cover most unshielded nets and the relevant structure of protective screening is installed.In actual use, run into after capping damages or capping is stolen, inspection shaft is open, has very big potential safety hazard, results in hand cramps to Pedestrians and vehicles.Only a few has the inspection shaft lid of protective screening, its protective screening fixing mainly is to hang by common hook or with hook that the base integrally casting forms, these hooks do not possess disconnecting prevention structure, in the big more weather of rainwater, the flowing water that sewer or underground passage spring up is washing away the inspection shaft lid, very easily will hang on protective screening on the hook and wash away and come off, if displacement takes place the capping of inspection shaft lid or when losing, will influence the safety of Pedestrians and vehicles.
The utility model content
The utility model will solve the problem that above-mentioned prior art exists, and it is firm to provide a kind of protective screening to install, and the Safety manhole cover that is difficult for getting loose solves the problem that there is potential safety hazard at present existing inspection shaft lid, satisfies safe and reliable urban infrastructure demand.
The utility model solves the technical scheme that its technical problem adopts: this band protective screening formula Safety manhole cover, comprise base 1, capping, the base inside wall fixedly has one group of hook, also be provided with one in the base by the protective screening of this hook tractive, rope on this protective screening crosses in hook, links up with the anticreep hook for preventing that the protective screening rope from making progress and.Like this, protective screening is installed by the anticreep tractive, even run into rainstorm weather during use, protective screening can not deviate from because of rain drop erosion yet, even if the capping of inspection shaft lid moves or loses, protective screening also can play emergent security protection effect.
The anticreep hook comprises the female bar that is embedded in the base, and female bar outer end is provided with the first circuitous portion that prevents that the protective screening rope from making progress and, and is provided with the gap between this first circuitous portion and the female bar.Like this, anticreep hook and base be individual components each other mutually, is convenient to produce and installs, and reduces and produces the cost of being correlated with; During installation, the rope of protective screening is snapped in from gap location, in the application, the rope of protective screening is restricted in the first circuitous portion, is difficult for deviating from from gap location.The cooperatively interacting in the first circuitous portion and gap down, even protective screening runs into powerful rain drop erosion or the external force effect takes place to float in the use, the rope of protective screening also can only activity in the first circuitous portion.
The first circuitous portion is upwards back made a circulation to extend to form by female bar outer end.Like this, be convenient to production and processing.
The gap is the assemblage gap that is provided for snapping in the protective screening rope between the end of the first circuitous portion and the female bar, and the distance of this assemblage gap is less than the diameter of protective screening rope.Like this, because the distance of assemblage gap is less than the diameter of protective screening rope, the rope floating range of protective screening greatly can not deviate from from assemblage gap easily yet, plays real protective action.
The integral body of the first circuitous portion tiltedly is located at female bar top, and the gap is the gap that snaps in that is provided for snapping in the protective screening rope between the sidepiece of the integral body of the first circuitous portion and female bar.Arrange like this, the direction that snaps in direction and rope that snaps in the gap is staggered, need change direction and just can pack into or split out when installation or removal, the situation of effectively avoiding the protective screening rope to deviate under non-artificial operation occurs.
The first circuitous portion formation extension that stretches out, the outer end height of this extension is lower than the height of female bar.Like this, can guarantee that the protective screening rope is held in the first circuitous portion all the time, is difficult for deviating from.
The first circuitous portion stretches out and forms the second circuitous portion that stops that the protective screening rope is deviate from backward.
The gap snap in protective screening rope in direction and the first circuitous portion to connect direction arranged in a crossed manner.Like this because the gap (be gap, assemblage gap and snap in the gap) to snap in direction and first direction of protective screening rope of making a circulation in the portion arranged in a crossed manner, the rope floating range of protective screening greatly can not deviate from from assemblage gap more easily yet, plays real protective action.
Female bar is fixed on the base inside wall by casting type or injection moulding formula.Normally cast molding or injection mo(u)lding of the production of inspection shaft lid in inspection shaft lid manufacturing process, just accomplished the Embedded Division of anticreep hook in the base, can promote the tensile property of anticreep hook greatly, and the fixation degree of raising protective screening is safe and reliable.
The bottom of base is provided with is convenient to install the annulus of building, and one group of equally distributed reinforcing rib is fixedly arranged between this annulus and the base side wall; The upper surface of capping is provided with one group of anti-skidding projection, sign projection, also has the hole that lifts that two positions are oppositely arranged on the capping, lifts the both sides, hole and is provided with and is convenient to the groove that the instrument that lifts inserts.Annulus is convenient to the installation of inspection shaft lid; When the inspection shaft lid is installed, this annulus is built in underground, inspection shaft lid and ground are maintained an equal level mutually, guarantee that path formation is unimpeded.Anti-skidding projection plays anti-skidding effect, avoids pedestrian's walking process because stepping on water stain the slipping on the inspection shaft lid capping; The sign projection is convenient to the capital construction personnel or the attendant can identify corresponding inspection shaft fast, in order to improve the efficient of installation, maintenance; Lifting the hole is be used to lifting the instrument insertion and mentioning capping, easy to operate simple, and water stain, ponding on the capping can be walked from lifting orifice flow, keep capping clean and tidy.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, compact, rational deployment setting by base, capping, anticreep hook, female bar, sidepiece, the first circuitous portion, end, second parts such as circuitous portion, protective screening and gap, make the inspection shaft lid in the utility model possess the protective screening that installation is firm, be difficult for getting loose, in use can play real protective action, prevent from when capping is lost or be damaged, influencing the safety of pedestrian or vehicle.Cost of the present utility model is reasonable, the security performance height, and result of use is good, is worthy to be popularized.
