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. 1-7, inspection shaft anti-drop device, comprises load-bearing protective cover 100 and three protective cover bracing frame 200(also can be that other are multiple).Load-bearing protective cover 100 and protective cover bracing frame 200 all adopt 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 ISO 179-1 marks, its corrosion resistance is also suitable excellence, can in moist, muddy atmosphere corrosion-resistant, resistance to oxidation etc. for a long time.
See Fig. 1,2 and 3, protective cover bracing frame 200 is arranged on below load-bearing protective cover in order to support load-bearing protective cover 100.The middle part of protective cover bracing frame 200 is provided with bolt connecting hole 210, is connected between protective cover bracing frame with catch pit port inwall by expandable nail.In the present embodiment, expandable nail is the plastic expansion nail that inside is embedded with metallic framework, and one end of expandable nail is taper pawl structure, is connected with catch pit port inwall, squeezes into catch pit port inwall, and strike tighter and tighter in case anti-avulsion falls by knocking.The other end of expandable nail is countersunk head structure, knocks in the counter sink of protective cover bracing frame, in order to avoid affect regular maintenance.Three equidistant circumference of protective cover bracing frame 200 are fixedly connected on catch pit port inwall.The upper surface of protective cover bracing frame is load bearing support face 220, load bearing support face is provided with spacing straight trough 221.The bottom of protective cover bracing frame is provided with strengthens brace rod 230.
See Fig. 4,5 and 6, 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 120 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.
Load-bearing protective cover is provided with three bayonet units corresponding with the spacing straight trough of protective cover bracing frame; This bayonet unit comprises the special-shaped slot 130 that is arranged on load-bearing protective cover and to be vertically inserted in this special-shaped slot and can to move along special-shaped slot the keeper 140 snapping in spacing straight trough, the locating slot portion 132 arranged in a crossed manner with spacing straight trough that special-shaped slot comprises body groove portion 131 and extends to form from side, body groove portion.See Fig. 7, when load-bearing protective cover is placed on protective cover bracing frame, make by rotating load-bearing protective cover, locating slot portion on load-bearing protective cover is corresponding with the spacing straight trough on protective cover bracing frame, running fix part, make it snap in spacing straight trough at the crossover location in spacing straight trough and locating slot portion, realize load-bearing protective cover and be connected with protective cover bracing frame buckle.
The lower surface of load-bearing protective cover is provided with the reinforcement gusset 150 along load-bearing protective cover radial direction, and this reinforcement gusset is arc-shaped side 151 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.
The utility model mounting or dismounting are convenient, can meet the bimonthly maintenance test of inspection well device completely, and while increasing work efficiency, operation is more light.In the monthly Inspection and maintenance of 2 times, dismounting simple operations is easy.Operating personnel's angle that do not need to bend is greater than 45 °, just can carry out safely dismounting load-bearing protective cover.
Install: with 6 expandable nails, three protective cover bracing frames are fixed on catch pit port inwall, and are positioned in same level, then load-bearing protective cover is put, and rotate to clamping.When catch pit port is of a size of 640mm, is fitted to each other place's width minimum, is 20mm, impact force requirement can be met.
The utility model is advised checking for 5 years and is changed once.Annual inspection later in 5 years once, is changed in time.In routine maintenance checking process, causing whole device to lose original protective action as found some special circumstances, should give replacing.
The utility model, compared with existing Antifalling down net for manhole, has the following advantages:
1, the life-span is long.Antifalling down net for manhole general application life is 2-3, and the utility model can use at least 5 years, generally can use 8-10.
2, safety factor, mainly considers pedestrian, takes into account vehicle.After the utility model installation, distance well head distance is 10cm, due to its good rigidly, after inspection well cover is opened, even if vehicle also can play cushioning effect after pressing, prevents automotive hub from damaging, and at utmost protects public's security of the lives and property.Antifalling down net for manhole surrounding gap is comparatively large, and pedestrian steps down rear appearance scaring because of carelessness and produces secondary injury.
3, economic factor.Antifalling down net for manhole often overlaps about 120 yuan of a life cycle use cost, 10 years use cost 260-300 units.And the utility model often overlaps about 150 yuan of a life cycle use cost, 10 years use cost 260-300 units.Calculate from maintenance cost and efficiency, the utility model has unrivaled advantage.
4, regular maintenance, the every 2-3 of Antifalling down net for manhole need change once, and maintenance frequency is high.And install and remove cumbersome, need workman closely to operate, potential safety hazard increases.The utility model did not need to carry out certain maintenance within 5 years, and had special tool to carry out remote-controlled operation, and worker safety is secure, and maintenance efficiency promotes greatly.
5, environmental protection, Antifalling down net for manhole must fix at least 8 metal trip bolts, and these screws need higher requirement for anticorrosion, and Treatment of Metal Surface brings comparatively serious ambient influnence.
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.
