Description
Technical field
The utility model relates to a kind of inspection shaft anti-drop device, prevents pedestrian or object from crashing into well from catch pit port.
Background technology
Inspection shaft be used in drainage pipe turning, branch, the place such as to fall so that check, the well of dredging, formal name used at school is in manhole.In like manner, be embedded in the telecommunication cable manhole of underground, power cable manhole, is also inspection shaft.
The well head of inspection shaft is all provided with inspection well cover, and existing inspection well cover adopts cast iron to make mostly, and be worth because material has to recycle, often stolen, loss situation is serious.In addition, when running into continuous heavy rain and causing urban road to soak, people's custom opens inspection well cover to accelerate draining, loses the import of inspection well cover, the pedestrian on ground or object occurs often and crashes into accident in inspection shaft, cause loss of personal property.
Chinese patent mandate publication number CN2718072Y discloses a kind of Antifalling down net for manhole, comprises well seat, has the soft string bag be connected with well seat, and this structure energy advantage is: when inspection well cover is lost, and it can prevent pedestrian or object from crashing in well effectively; When needing emergent draining when urban road immersion, also can prevent pedestrian or larger object from crashing in well even if open well lid.But owing to being subject to the restriction of the material of the soft string bag own, when long-time use, there is the phenomenon polluted by Sewage Environment in the soft string bag.
Chinese patent mandate publication number CN204475372U discloses the anti-fall well lid of a kind of inspection shaft, the lid comprising well seat and match with described well seat, wherein, is provided with carriage at the inwall of described well seat, in order to realize the support to described lid; In described well seat, be also provided with fall arrest lid, the edge of described fall arrest lid is outward extended with two or more card article; Described carriage offers the groove corresponding with the quantity of described card article, and the card article of described anti-fall inner cap can fall in described groove, realizes the fixing of described fall arrest lid.But this structure needs to install carriage at the inwall of well seat, and in order to realize the support to described lid, the installation difficulty of carriage is high, installs and dismantle inconvenient.
Utility model content
For the problems referred to above, the utility model provides a kind of suspension type inspection shaft anti-drop device, installs inconvenient problem to solve the anti-fall well lid of inspection shaft in prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Suspension type inspection shaft anti-drop device, is characterized in that, comprises load-bearing protective cover and is connected to the suspender on load-bearing protective cover; On described load-bearing protective cover, circle distribution has connecting hole, and described suspender is connected by the connecting hole of connection cord with load-bearing protective cover; Described suspender comprises one for being suspended on the suppending hole on catch pit port inwall bolt.
In the utility model, described suppending hole is bolt can be allowed to slide up and down, to facilitate suspender to be connected to waist hole on catch pit port inwall.
In the utility model, the top of described suspender comprises so that lift the hand-held hole of suspender.Further, the top of described suspender is "the" shape structure.
In the utility model, the bottom of described suspender is provided with so that the connecting hole of connection cord connection.
In the utility model, described load-bearing protective cover is provided with weep hole.
The utility model, when inspection well cover is stolen or when opening because of emergent draining, effectively can prevents pedestrian or object from crashing in inspection shaft, avoid causing loss of personal property.
Load-bearing protective cover of the present utility model is arranged on catch pit port by suspender, reduces installation difficulty, is easy to manufacturing operation, simultaneously safe and reliable, energy-conserving and environment-protective.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better embodiment of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of load-bearing protective cover.
Fig. 2 is the schematic diagram of suspender.
Fig. 3 is partial schematic diagram of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 1 and 3, suspension type inspection shaft anti-drop device, the suspender 200 comprising load-bearing protective cover 100 and be connected on load-bearing protective cover.
Load-bearing protective cover 100 adopts the reinforced plastics adding glass fiber, and its maximum feature is that hot strength is high, and shock resistance is good.Tensile strength is >100MPa under ISO527-1 standard, simply supported beam unnotched impact strength is >25Mpa under ISO179-1 mark, its corrosion resistance is also suitable excellence, can in moist, muddy atmosphere corrosion-resistant, resistance to oxidation etc. for a long time.
Load-bearing protective cover 100 is used to prevent people or object from crashing in inspection shaft, and the outer contour shape of load-bearing protective cover 100 is circular, load-bearing protective cover is provided with weep hole 110.Information identifier region 130 is left in the center of load-bearing protective cover 100, and much information such as statement region, maintenance telephone number etc., is convenient to Timeliness coverage problem like this and manages.
The lower surface of load-bearing protective cover 100 is provided with the reinforcement gusset along load-bearing protective cover radial direction, and this reinforcement gusset is arc-shaped side outstanding downwards below.Power more can be rapidly dispersed into the various piece of anti-fall cover by the reinforcement gusset of this structure when it is subject to impacting, strengthen the impact strength of anti-fall cover with this.
On load-bearing protective cover, circle distribution has connecting hole 120, and suspender 200 is connected with the connecting hole 120 of load-bearing protective cover by connection cord 300.
See Fig. 2, suspender 200 comprises one for being suspended on the suppending hole 210 on catch pit port inwall bolt.Suppending hole 210 is bolt can be allowed to slide up and down, to facilitate suspender to be connected to waist hole on catch pit port inwall.
The top of suspender is "the" shape structure.The top of suspender comprises so that lift the hand-held hole 220 of suspender.The bottom of suspender is provided with so that the connecting hole 230 of connection cord connection.
During use, in advance at catch pit port inwall erection bolt, load-bearing protective cover 100 to be placed in below bolt and horizontal positioned, to be suspended on bolt by the suspender 200 be connected with load-bearing protective cover 100.Load-bearing protective cover is arranged on catch pit port by suspender, reduces installation difficulty, is easy to manufacturing operation, simultaneously safe and reliable, energy-conserving and environment-protective.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and manual; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
