Description
Technical field
The utility model relates to urban infrastructure field, particularly relates to a kind of high-strength anti-theft cover for manhole.
Background technology
Along with the quickening of urbanization paces, the gradual perfection that road administration is built, well lid becomes the part that urban road be can not ignore.In recent years, the many social concerns caused because of well lid insufficient strength or disappearance also cause the concern of people often.Well lid is intercept the barrier between underground installation and ground, and provide safety guarantee for road surface normal pass uses, traditional well lid is easy to use, but does not have anti-theft feature, and travels frequent section at truck, often occurs well lid fracture, damaged condition.Because the making raw material of well lid are mostly recoverable metal material, cause lawless person to steal and peddle well lid phenomenon wildness, bring safely serious threat to national public property, also cause serious infringement to life property safety of people simultaneously.In recent years, the security incident caused because of road surface manhole disappearance happens occasionally, and causes many irremediable serious consequences, also brings the social influence of very severe simultaneously.For this manhole cover loss, damaged phenomenon, road administration regularly can only be checked to supplement and be changed, and reduces this infringement as far as possible.But the potential safety hazard of intervening vacancy during this period of time at manhole cover damage or loss to road administration but can not be ignored.
Summary of the invention
According to above technical problem, the utility model provides a kind of safe and reliable, high-strength anti-theft cover for manhole with low cost, comprise well lid and well seat, characterized by further comprising electronic password lock, netted reinforcing rib, reinforce key, keyway, well lid is fixed on well seat, the well lid back side is the netted reinforcing rib with well lid integrally casting, electronic password lock is embedded is arranged on well lid center, electronic cipher lock bottom is a rotation roulette, rotation roulette is connected with linking springs one end, the linking springs other end is connected with reinforcing key, reinforcing key is fixed on bottom well lid through the through hole on netted reinforcing rib, reinforce keyway below key and well lid with the use of.
The beneficial effects of the utility model are: the utility model is provided with electronic password lock, electronic password lock control reinforcing key coordinates with keyway, form intelligence control system, easy to operate, can securely well lid be fixed, under locking state, if remove coded lock by force, then keyway is in closure state, and dismounting well lid is more difficult, serves good anti-theft function to well lid.At pattern manhole cover lock after death, the keyway of annular distribution can play fixed support in the junction of well lid and well seat and disperse stressed effect, improves the compressive strength of well lid, extends the application life of well lid.Well lid is the disposable cast member of steel fiber reinforced concrete; it is netted reinforcing rib structure bottom well lid; compared with common radial reinforcing rib; netted reinforcing rib compressive property is more firm; the load diatibution in well lid face evenly; locally transship the destruction of causing when can reduce being hit property of well lid External Force Acting, well lid is played a very good protection.
The utility model high-strength anti-theft cover for manhole theftproof is good, compact conformation, stress equalization, and compressive strength is large, and resist damage capability strong, casting material functional performance is good, long service life.Be applicable to heavy vehicle running section, the underground installation entrance seldom opened.

Detailed description of the invention
Existing composition graphs 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 are further described the utility model.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of high-strength anti-theft cover for manhole, comprise well lid 1 and well seat 6, well lid 1 is fixed on well seat 6, the netted reinforcing rib 2 of casting is integrated bottom well lid 1, netted reinforcing rib 2 there is the through hole 3 got out, reinforcing key 4 is fixed on well lid 1 through through hole 3, well lid 1 is provided with electronic password lock 7, it is a rotation roulette 8 bottom electronic password lock 7, reinforce key 4 one end to be connected by linking springs 9 with rotation roulette 8, reinforce the keyway 5 below key 4 other end fill-in well seat 6.By manipulation electronic password lock 7, the rotary motion of rotation roulette 8 bottom electronic password lock 7 can be controlled, rotation roulette 8 rotarily driven the flexible of linking springs 9 on it, thus the displacement of radial direction that the reinforcing key 4 that connects of control connection spring 9 other end limits at through hole 3.
Input password, unlocking electronic password lock 7, rotation roulette 8 rotates, and drives linking springs 9 to stretch, rotate, and meanwhile, reinforce key 4 under the pulling force effect of linking springs 9, move to direction, well lid 1 center of circle, exit keyway 5, well lid 1 is opened.Cover well lid 1, rotate the position regulating well lid 1, make one end of reinforcing key 4 aim at keyway 5, close coded lock 7, rotation roulette 8 spinning reduction, linking springs 9 resilience is shunk, reinforce key 4 linking springs 9 shrink back elastic force effect under, the radial direction limited along through hole 3 moves to the direction deviating from well lid 1 center of circle, reinforces the other end of key 4 and gives prominence to well lid 1 edge, keyway 5 below fill-in well seat 6, well lid 1 is fixed locked on well seat 6.
