Abstract
The utility model relates to well cover installation, in particular to a well cover used in a tunnel, which comprises an upper cover, a bottom frame and booster air pumps; wherein one ends of the booster air pumps are connected with the upper cover, and the other ends thereof are connected on the bottom frame; and a lock is arranged on the upper cover and can lock the well cover. The well cover used in the tunnel has the advantages that the structure is simple, the stability of the well cover is increased so as to lead the well cover to have strong bearing, the use is flexible and convenient, and the force is small; the well cover has self-locking, anti-bouncing and certain water leakage capability, not only can be used for the escape exit in the tunnel, but also can be used for the overhaul pass exit.
Description
Technical field
The utility model relates to well lid class is installed, and particularly relates to a kind of well lid that is used in the tunnel.
Background technology
Upper and lower pipeline and road surface manhole all will have stronger bearing capacity in urban construction, major part is the cast iron manufacturing, as folding paper well lid, anti-stealing manhole cover etc., present manual power-assisted well lid does not have shaped article at home, external product adopts stainless steel to make well lid and underframe, cost is high and do not have a large scale specification product, in existing various pipes and the road surface manhole, but the well lid that power-assisted is opened is rarely found, generally be to adopt electrical equipment or the large-scale well lid of hydraulic-driven, but system complex, it is high to safeguard that debugging requires, cost is higher, is difficult for promoting the use of.Therefore when running into emergency such as fire by escape way, when evacuate the emergency exit, occur well lid easily and be difficult for opening or do not open or phenomenon such as difficult sealing, can cause damage to personal property.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of well lid that is used in the tunnel is provided, between loam cake in this well lid structure and the underframe power-assisted air pump is installed, and lockset is set last covering, can guarantee when in satisfying the tunnel, bearing, the steadiness of well lid being required that this escape manhole can be by artificial safe, reliably, open easily.
The utility model purpose realizes being finished by following technical scheme:
A kind of well lid that is used in the tunnel is characterized in that being that this well lid comprises loam cake, underframe, power-assisted air pump, and wherein an end of power-assisted air pump is connected with loam cake, and the other end is connected on the underframe.
Last covering the lockset that can lock well lid is installed.
Described lockset comprises rack and pinion drive, dead bolt and two driving handles, and wherein driving handle connects dead bolt by rack and pinion drive.
Adopt hinge to connect between one side of described loam cake and the side of underframe.
Described power-assisted air pump adopts two at least.
The utility model has the advantages that simple in structure, the steadiness that has increased well lid makes its bearing strong, use flexible, convenient, firmly little, have self-locking, anti-jump and certain percolation-proof ability, this well lid not only can be used for escaping exit place in the tunnel, also can be used for overhauling simultaneously current mouthful of place.
Description of drawings
Accompanying drawing 1 is the loam cake Unclosing structure schematic diagram of the utility model after installing;
Accompanying drawing 3 is the utility model loam cake bottom surface structural representation.
The specific embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, always representing respectively in the accompanying drawing: loam cake 1, underframe 2, power-assisted air pump 3, lockset 4, handle 5, dead bolt 6 with reference to label 1-6.
The present embodiment well lid comprises loam cake 1, underframe 2 and power-assisted air pump 3, loam cake 1 wherein has been connected through the hinge on the underframe 2, between loam cake 1 and underframe 2, connect on the symmetric position two power-assisted air pumps 3 are set, one end of power-assisted air pump 3 is installed on the reservation free bearing below the loam cake 1, the other end is installed on the reservation free bearing of underframe 2, forms the air spring effect between underframe 2 and loam cake 1, reaches the function that reduces opening force.
The escape manhole of present embodiment, have from all openable lockset 4 of upper and lower (track layer and passway for escaping), the combination of well lid and lockset makes well lid have anti-jump measure, prevent that loam cake is subjected to wheel load that the generation of spring or unexpected unlatching situation takes place, pressure wheel is crossed does not have the spring noise, does not influence the driving comfort.Open loam cake in the use, the power-assisted air pump can automatically be opened, and escape manhole can be by single light unlatching, and opening force is less than 15kg, and the well lid opening angle is greater than 90 degree, can prevent the well lid closure that glides rapidly after the unlatching.
Above-mentioned escape manhole load-bearing property is good, can satisfy the highway-I level load requirement among the JTG D60-2004 " highway bridge and culvert universal design standard ".Adopt the material of ductile iron, the agent structure wear-and corrosion-resistant as well lid and underframe.Well lid adopts and is fire proofing, reaches fire protection requirement.Well lid adopts the rubber strip sealing, has certain air-tightness and watertightness performance.
Claims (5)
