Abstract
The invention relates to assembly of well covers, in particular to an escape well cover in a tunnel. The well cover comprises an upper cover, a bottom frame and a power-assisted air pump, wherein one end of the power-assisted air pump is connected with the upper cover and the other end of the power-assisted air pump is connected with the bottom frame; and a lockset capable of locking the well cover is arranged on the upper cover. The escape well cover in the tunnel has the advantages that the escape well cover has a simple structure and strong bearing property due to increase of the stability of the well cover, uses small force, is flexible and convenient to use, has the abilities of self-locking, creepage resistance and seepage resistance, and not only can be used on an escape scuttle in the tunnel but also can be used on an access hole.
Description
Technical field
The present invention relates to well lid class is installed, particularly relate to a kind of escape manhole in tunnel.
Background technology
In urban construction, upper and lower pipeline and road surface manhole all will have stronger bearing capacity, major part is the cast iron manufacture, as folding paper well lid, anti-stealing manhole cover etc., current manual power-assisted well lid is at home without shaped article, external product adopts stainless steel to make well lid and underframe, cost is high and there is no a large scale specification product, in existing various pipes and road surface manhole, but the well lid that power-assisted is opened is rarely found, be generally to adopt electrical equipment or the large-scale well lid of hydraulic-driven, but system complex safeguard that commissioning requirements is high, cost is higher, is difficult for promoting the use of.Therefore when emergencies such as running into fire is evacuated by escape way, emergency exit, easily occur that well lid is difficult for opening or does not open or the phenomenon such as difficult sealing, can cause damage to personal property.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of escape manhole in tunnel is provided, the power-assisted air pump is installed between the upper cover in this manhole cover structure and underframe, and upper covering, lockset is set, can guarantee when in meeting tunnel, bearing, the steadiness of well lid being required that this escape manhole can be by artificial safe, reliably, open easily.
The object of the invention realizes being completed by following technical scheme:
A kind of escape manhole in tunnel, is characterized in that being that this well lid comprises upper cover, underframe, power-assisted air pump, and wherein an end of power-assisted air pump is connected with upper cover, and the other end is connected on underframe.
Upper 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 chain connection between one side of described upper cover and a side of underframe.
Described power-assisted air pump at least adopts two.
Advantage of the present invention is 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 tunnel, also can be used for overhauling current mouthful of place simultaneously.
The accompanying drawing explanation
Accompanying drawing 1 is the upper cover Unclosing structure schematic diagram after installing for the present invention;
Accompanying drawing 2 is mounted configuration schematic diagram of the present invention;
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, feature of the present invention and other correlated characteristics are described in further detail, so that technician's of the same trade understanding:
As Figure 1-3, always meaning respectively with reference to label 1-6 in accompanying drawing: upper cover 1, underframe 2, power-assisted air pump 3, lockset 4, handle 5, dead bolt 6.
The present embodiment well lid comprises upper cover 1, underframe 2 and power-assisted air pump 3, upper cover 1 wherein has been connected through the hinge on underframe 2, between upper cover 1 and underframe 2, connect two power-assisted air pumps 3 are set on symmetric position, one end of power-assisted air pump 3 is arranged on the following reserved free bearing of upper cover 1, the other end is arranged on the reserved free bearing of underframe 2, forms the air spring effect between underframe 2 and upper cover 1, reaches the function that reduces opening force.
The escape manhole of the present embodiment, have from upper and lower (track layer and passway for escaping) openable lockset 4 all, the combination of well lid and lockset makes well lid have anti-jump measure, prevent that upper cover is subject to wheel load that the generation of spring or unexpected unlatching situation occurs, pressure wheel is crossed without the spring noise, does not affect the driving comfort.Open upper cover in 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 unlatching.
Above-mentioned escape manhole load-bearing property is good, can meet JTG D60-2004 " highway bridge and culvert universal design standard >>Zhong highway-I level load requirement.Adopt the material of ductile iron as well lid and underframe, the agent structure wear-and corrosion-resistant.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 (2)
1. an escape manhole in tunnel, it is characterized in that being that this well lid comprises upper cover, underframe, power-assisted air pump, wherein an end of power-assisted air pump is connected with the reserved free bearing below upper cover, the other end is connected on the reserved free bearing of underframe, described power-assisted air pump at least adopts two, upper covering, the lockset that can lock well lid is installed, described lockset comprises rack and pinion drive, dead bolt and two driving handles, wherein driving handle connects dead bolt by rack and pinion drive, utilize the rack-and-pinion transmission, 2 dead bolts are controlled in interlock, reach the function with underframe locking.
2. escape manhole in tunnel according to claim 1, is characterized in that being: between a side of described upper cover and a side of underframe, adopt chain connection.
