The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the utility model.
Referring to Fig. 1-6, portable inspection shaft anti-drop device, comprises that the anti-fall cover 100 of load-bearing and three anti-fall cover bracing frame 200(can be also that other are a plurality of).The anti-fall cover 100 of load-bearing and anti-fall cover bracing frame 200 all adopt the reinforced plastics that has increased 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 mark, its corrosion resistance is also suitable excellence, can be in moist, muddy atmosphere corrosion-resistant, resistance to oxidation etc. for a long time.
Anti-fall cover bracing frame 200 is arranged on the anti-fall cover periphery of load-bearing in order to support the anti-fall cover 100 of load-bearing.The middle part of anti-fall cover bracing frame 200 is provided with bolt connecting hole 210, between anti-fall cover bracing frame and catch pit port inwall, by expandable nail, is connected.In the present embodiment, expandable nail is the inner plastic expansion nail that is embedded with metallic framework, and one end of expandable nail is taper pawl structure, is connected with catch pit port inwall, by knocking, squeezes into catch pit port inwall, and strikes tighter and tighter in case anti-avulsion falls.The other end of expandable nail is countersunk head structure, knocks in the counter sink of anti-fall cover bracing frame, in order to avoid affect regular maintenance.Three equidistant circumference of anti-fall cover bracing frame 200 are fixedly connected on catch pit port inwall.The upper surface of anti-fall cover bracing frame is supporting plane 220, and the left side of anti-fall cover bracing frame is provided with the stopper protrusion 230 that prevents that the anti-fall cover of load-bearing from moving, and the lower surface of stopper protrusion is provided with some groups of locating slots 231; Stopper protrusion 230 comprises that, to the conical surface 232 in order to the anti-fall cover of tight connection load-bearing of center of circle direction inclination, the container cavity that connects draw-in groove is corresponding with stopper protrusion.The bottom of anti-fall cover bracing frame is provided with strengthens brace rod 240.The outer wall upper end of anti-fall cover bracing frame is provided with is convenient to the notch part 250 that crowbar prizes.
The anti-fall cover 100 of load-bearing is for preventing that people or object from crashing in inspection shaft, the outer contour shape of the anti-fall cover 100 of load-bearing is circular, on the anti-fall cover of load-bearing, be provided with weep hole 110, in the present embodiment, weep hole 110 is circular in configuration trapezoidal hole that arrange and that be the outside divergence expression structure of ring by ring.Certainly, weep hole can be also square hole, diamond hole or tri-angle-holed etc.Information identifier region is left in the center of the anti-fall cover 100 of load-bearing, and the much informations such as statement region, maintenance telephone number, are convenient to pinpoint the problems in time and manage like this.The lower surface 120 of the anti-fall cover of load-bearing is erected on the anti-fall cover of load-bearing, is also provided with the connection draw-in groove 130 that connects stopper protrusion in order to suit on the lower surface of the anti-fall cover of load-bearing, and the lower trough rim that connects draw-in groove is provided with to block the snap fit 131 of locating slot.The anti-fall cover of load-bearing blocks stopper protrusion by rotation to the right.On the anti-fall cover of load-bearing and anti-fall cover bracing frame, be provided with corresponding through hole, after the anti-fall cover of load-bearing is arranged on anti-fall cover bracing frame, described lead to the hole site overlaps, and inserts in through hole described two parts are positioned with spline pin.In addition, connect draw-in groove dorsad a side of stopper protrusion reinforcing rib 140 is set.
Answer >=200kg of the static bearing capacity of the utility model, answer >=100kg of shock-resistant bearing capacity.
The utility model mounting or dismounting are convenient, can meet the bimonthly maintenance test of inspection shaft device completely, and operation is more light when increasing work efficiency.In the Inspection and maintenance of 2 times monthly, dismounting simple operations is easily gone.Operating personnel's angle that do not need to bend is greater than 45 °, just can carry out safely the anti-fall cover of dismounting load-bearing.
Install: with 6 expandable nails, three anti-fall cover bracing frames are fixed on catch pit port inwall, and are positioned in same level, then the anti-fall cover of load-bearing is put, and rotation is to clamping.When catch pit port is of a size of 640mm, being fitted to each other place's width minimum, is 20mm, can meet impact force requirement.
Make special-purpose regular maintenance dismantling device, this instrument is comprised of light metal material, and a design curved metal claw of Flat belt in termination is used for mobile plastic safety lid, and an other side arranges a hook, is used for tension or draw loose safety head.
The utility model suggestion checks and changes once for 5 years.Annual inspection later in 5 years once, is changed in time.In routine maintenance checking process, as found some special circumstances, cause whole device to lose original anti-fall effect, should give replacing.
The utility model is 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 be used 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 that automotive hub from damaging, and at utmost protects public's security of the lives and property.Antifalling down net for manhole surrounding gap is larger, and pedestrian steps down because of carelessness rear appearance scaring and produces secondary injury.
3, economic factor.About 120 yuan of life cycle use cost of the every cover of Antifalling down net for manhole, 10 years use cost 260-300 units.And about 150 yuan of life cycle use cost of the every cover of the utility model, 10 years use cost 260-300 units.From maintenance cost and efficiency, calculate, 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 cumbersomely, 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 be fixed at least 8 metal trip bolts, and these screws need to have higher requirement for anticorrosion, and Treatment of Metal Surface is brought comparatively serious ambient influnence.
More than show and described basic 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; what in above-described embodiment and manual, describe is principle of the present utility model; under the prerequisite that does not depart 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.
