Abstract
The invention discloses a well lid, a lifting device of the well lid and a use method of the well lid. The well lid comprises a well lid body and the lifting device of the well lid, wherein a straight wall blind hole is formed in the well lid body, the lifting device of the well lid comprises a first side plate, a second side plate, a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are hinged to the first side plate and the second side plate respectively, and the first side plate, the second side plate, the first connecting rod and the second connecting rod form a parallel four-bar linkage. When the parallel four-bar linkage is in a rectangular shape, the distance between the outer side of the first side plate and the outer side of the second side plate is larger than the diameter of the straight wall blind hole, and when the parallel four-bar linkage is inserted into the straight wall blind hole, an inclined angle alpha is formed between the first connecting rod and the horizontal line, wherein alpha is smaller than or equal to the friction angle beta between the first side plate and the well lid body and the friction angle beta between the second side plate and the well lid body, beta equals to arctanf, and f is the friction coefficient between the first side plate and the well lid body and the friction coefficient between the second side plate and the well lid body. The well lid is quite obvious in anti-theft effect, the anti-rust problem of the well lid is effectively solved, and the well lid and the lifting device are simple in structure, low in cost and convenient to use and have great practical value.
Description
Technical field
The present invention relates to a kind of well lid and pull up device and using method.
Background technology
Well lid plays very important effect in our daily life, is the important ingredient of municipal sewage system system, extensively appears at each corner in the cities such as community, road.At present, all need to be in provided underground as multiple pipelines such as water, electricity, communications at city farm-to-market road, and for observing or overhaul the well head of subterranean pipe line, what great majority adopted is the well lid that cast iron materials is manufactured, because the well lid of cast iron quality has certain recovery value, and the current very imperfection of anti-theft measure for well lid, so well lid is very easily stolen, light cause national property loss owing to filling up the disappearance of well lid, heavy because the trap forming in the stolen rear road of well lid causes personal injury event; In addition, the article that very easily cause because well lid is stolen in subterranean pipe line are lost or damage, as the cable in the subterranean pipe line of electric power or communication section or pipe fitting etc.; The imperfection of manhole cover anti-theft measure has not only strengthened the expense of relevant departments aspect safeguarding, also the corresponding expense that has caused the departments such as electric power, communication and tap water strengthens, simultaneously, due to loss and the damage of well lid, the pedestrian that walks or the safety of vehicle have been threatened again on road, cause unnecessary loss therefore to country and the common people, caused accordingly the waste of unnecessary manpower and materials and loss economically; Now, the caused social concern of the problem of well lid safety, has become a major hidden danger in urban safety.
In Chinese Patent Application No.: disclose a kind of anti-stealing manhole cover in 201310339915, comprise inspection well cover framework 111 and inspection well cover lid 311 etc., owing to anti-theft screw being housed on inspection well cover lid 311 and can turn flexible antitheft traverse latch etc. is housed for 313 times in inspection well cover bottom surface, and is respectively furnished with its assembly and Disassembly special tool, unless made outside its special tool of this technical scheme, be that other any instruments all cannot be installed and removed, thereby reached object that can be very antitheft.But, this technical scheme complex structure, cost is high, and operation is inconvenient, also can't resolve the problem of " rust protection " of well lid.
In Chinese Patent Application No.: disclose a kind of well lid in public arena of can making that relates to road administration facility field in 201010501429 and possessed the manhole antitheft lock of anti-theft feature, described manhole antitheft lock forms a whole set of lockset by locking frame, spring, movable post, locking bolt, removable pin, steady pin and key clamp, and employing and the supporting key of lockset is opened or locking described in theftproof lock; During enforcement, by produce afterwards supporting to described manhole antitheft lock and corresponding well lid simultaneously, or according to existing well lid, produce separately described manhole antitheft lock, then corresponding part is fixedly installed to behind the supporting well lid back side and this well lid can be used in public.This technical scheme complex structure, cost is high.
In Chinese Patent Application No.: a kind of anti-theft and waterproof drain well cover is disclosed in 201010265969, its upper surface uniform two round pools that keep to the side, there is circular hole round pool center; Screw is screwed in the walling crib screw in build-in ground through this two circular hole, and well lid walling crib is connected; Plug welding locking plate on head of screw, manpower hand-held tool cannot open manhole cover.Inspection shaft is managed household affairs after the locking plate of available cutting equipment excision plug welding, unloads screw with box spanner, then lifts covers with T-shaped hook.This well lid does not have open hole, aluminium backing on head of screw underlay, and it is just waterproof that well lid and walling crib binding face fill plastic sealing water.This technical scheme complex structure, can't resolve the problem of well lid " rust protection ".
Summary of the invention
For the problems referred to above, the invention provides a kind of anti-theft effect obvious, and well lid simple in structure and pull up device and using method.
In order to address the above problem, technical scheme provided by the invention is:
A kind of well lid, comprises well lid body, has straight wall blind hole on described well lid body; On well lid body due to design, have straight wall blind hole, other apparatuses do not have stress point, are difficult to extract well lid, only have and could extract with the special device that pulls up, so anti-theft function is very obvious.
Preferably, described straight wall blind hole is provided with cover plate, and described cover plate and described well lid body are hinged; Under normal circumstances straight wall blind hole is covered, thereby do not affect the safety of normal pedestrian, driving.
Described well lid pull up device, comprise first, second side plate, first, second connecting rod, described first, second connecting rod is hinged with described first, second side plate respectively; Described first, second side plate and described first, second connecting rod form parallel four-bar linkage; When described parallel four-bar linkage is orthogonal, described first, second side plate separately distance between outside is greater than the diameter of described straight wall blind hole; When described parallel four-bar linkage inserts described straight wall blind hole, described first connecting rod and horizon form angle α, described α is less than or equal to the angle of friction β of described first, second side plate and described well lid body, β=arctanf, described f is the friction factor between described first, second side plate and described well lid body; By such design, allowing described parallel four-bar linkage and well lid body produce self-locking is connected as a single entity, conveniently pulls up well lid.
Preferably, the external surface of described first, second side plate is outer convex; Increase the contact area of described first, second side plate and described well lid body.
Preferably, also comprise third connecting rod, described third connecting rod and described first, second side plate are hinged, and described third connecting rod is parallel with described first, second connecting rod, and are arranged between described first, second connecting rod.
