Background technology
Municipal sewage well of the prior art or various professional manhole, generally all adopt casting iron well lid, this well lid cost of production is higher, and it is very serious particularly to be stolen phenomenon in recent years, often has in the city to lose to the accident that makes pedestrian or damaged vehicle because of well lid to take place.For this reason, various nonmetals well lids begin to use gradually, as: cement well lid, ceramic well lid, manhole cover made of magnesite composite material, polyester composite well lid etc.
Yet these well lids one are insufficient strength, and are easily broken, stay potential safety hazard easily; The 2nd, weight is big, operation inconvenience, and not attractive in appearance; The 3rd, sealing effectiveness is bad, leaks the rainy day constructional difficulties in well; The 4th, do not have anti-theft feature, often go adrift, not only caused economic loss, also make pedestrian's safety be subjected to serious threat.These shortcomings cause the nonmetals anti-stealing manhole cover to be applied and are restricted.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, cost is low, intensity is high, anti-leaking and the nonmetals anti-stealing manhole cover of theft protection.
Another purpose of the present utility model is to provide a kind of volume small and exquisite, carries and well lid hoisting device easy to use.
The purpose of this utility model is achieved in that a kind of nonmetals anti-stealing manhole cover, cage of reinforcement by nonmetals and nonmetals inside constitutes, well lid is the big following little truncated conical shape of diameter of top diameter, it is characterized in that: the hole for hoist that vertically runs through well lid is arranged at the center of well lid, this hole for hoist constitutes by being welded on two sections steel pipes that dock on the cage of reinforcement, wherein the epimere pipe diameter is thin, and the hypomere pipe diameter is thick; In hole for hoist, be provided with the water proof rubber plug, be provided with cannelure, in cannelure, place the ring-shaped rubber sealing ring in the side of truncated conical shape well lid.
Described cage of reinforcement is made of top mat and the lower floor's steel mesh reinforcement that several vertical reinforcing bars connect, and wherein top mat is that the reinforcing bar of 4～8mm constitutes by diameter, and lower floor's steel mesh reinforcement is that the fried dough twist steel of 14～18mm constitutes by diameter.
The epimere diameter of steel tube of described formation hole for hoist is 18～22mm, and length is 20～80mm; The diameter of hypomere steel pipe is 28～32mm.
Described rubber seal is the hollow rubber circle.
Another order of the present utility model is achieved in that a kind of well lid hoisting device that is used to open above-mentioned nonmetals anti-stealing manhole cover, it is characterized in that: it comprises a pull bar, the upper end of pull bar is a hoisting ring, the lower end of pull bar is the tapered expansion piece, one sleeve is set on pull bar, the sleeve upper end is spherical spacing ring, and 2～3 elastic card claws are fixed in the sleeve lower end, on the pull bar between hoisting ring and the spherical spacing ring support spring are arranged.
The tapered expansion piece of described pull bar lower end can adopt screw thread to be connected with pull bar, in the lower end of pull bar external screw thread is arranged, and the tapered expansion piece has the screwed hole that adapts with pull bar lower end external screw thread.This design can be adjusted the length of hoisting device by the rotary conic expanding block, adapts to the lifting demand of different depth hole for hoist well lid.
Carry for convenience, this hoisting device comprises that also a side is provided with the portable sleeve pipe of hook, and the internal diameter of this portable sleeve pipe is greater than tapered expansion piece bottom surface diameter, less than expanding block bottom surface diameter and two elastic card claw thickness and.Hoisting device can be with this portable sheath pipe box on the sleeve of hoisting device when not using, under the effect of support spring and elastic card claw, should be fixed between spherical spacing ring and the tapered expansion piece by portable sleeve pipe, it makes this hoisting device good looking appearance, be convenient for carrying, because its volume is little, can be by dropper clamps in the shirt pocket.
The utility model compared with prior art has following advantage: the utility model well lid inside is provided with cage of reinforcement, and the reinforcement ratio of following cage of reinforcement net is thicker, and such structural strength height is not easy fragmentation, and carrying gravity is big, does not have potential safety hazard; Owing to be provided with water proof rubber plug and rubber seal at hole for hoist and well lid sidewall, make its good sealing effect, in well, do not leak; Because well lid is heavier, described hole for hoist diameter is smaller, and amateur instrument can not fall well lid, so have anti-theft effect.
For well lid having been fallen, the utility model has also designed a well lid hoisting device, and this hoisting device is simple in structure, and volume is small and exquisite, and is reasonable in design, is easy to carry, easy to use.
