Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Configured with escape well in tunnel, which is used as escape when emergency episode occurs, and escape well is logical by underground
Road and extraneous connection.The well lid of escape well is usually also serving as traffic, therefore the well lid for well of escaping usually has metal or cement
It pours, the weight of well lid is very big.The present invention mainly improves the mounting structure of well lid and unfolding mode, and the following are detailed
Carefully describe.
Tunnel escape well 300, including well lid 100, lever assembly 400 and Weighting system, lever assembly 400 are fixed on well lid
On 100, Weighting system is connect with lever assembly 400.It opens up blackout on the wall of tunnel escape well 300 and is stamped crib 101, well lid
100 Gai Hehou are fallen on crib 101.Tunnel escape well 300 includes slide escape 301, after well lid 100 is opened, escape personnel
It can quickly be slided from slide escape 301.
As depicted in figs. 1 and 2, the Weighting system of tunnel escape well, including connect by the first traction rope 10 with well lid 100
Clump weight 200 and the driving mechanism 20 that is connect with clump weight 200, driving mechanism 20 includes second connect with clump weight 200
Traction rope 21 and hand tractor 30, hand tractor 30 are matched by controlling the collapsing length of the second traction rope 21 to realize
The adjustable height of pouring weight 200.
Preferably, the first traction rope 10 is fixed on the roof of escape well around one after the extraction of clump weight 200 and determines cunning
Wheel 302, then connect with well lid 100.
More specifically, which is fan shape component, and the narrow portion E of fan shape component is fixed on well lid 100
Downside, one end of the first traction rope 10 be connected to one end wide portion F of fan shape component and behind the bottom of entire width portion F again
Around the fixed pulley 302 on roof, last first connecting rope 10 is connect with clump weight 200, and the first traction rope 10 and sector
Open side of the connecting pin b of shape component in the horizontal direction far from well lid 100.
As shown in Figure 1, clump weight 200 gives 10 1 active forces of the first traction rope under first state, the first traction rope 10 is drawn
The connecting pin end b of dynamic lever assembly 400, so that 400 stress of lever assembly, finally opens the well lid 100 of tunnel escape well.Thick stick
400 stress of bar assembly so that well lid 100 open specific technical solution, publication No. be CN108104173A patent in
It is open, thus this is not repeated.
As shown in Fig. 2, eliminating clump weight 200 to the active force of the first traction rope 10, the first traction rope 10 under the second state
The pulling force being applied on the connecting pin b of fan shape component disappears, then well lid 100 is closed under the action of lever assembly 400 is self-possessed.
Or after escape personnel enters tunnel internal, artificially apply an active force to well lid 100 so that well lid 100 is closed.
Preferably, the first traction rope 10 and the second traction rope 21 can be wirerope.
Hand tractor 30 is hand-rail type winch assemblies.
As shown in Figures 3 to 6, specifically, which includes traction rope storage tray 31, driving gear set 32
With hand component 33, hand component 33 is connect by driving gear set 32 with traction rope storage tray 31, and shaking hand component 33 makes
Traction rope storage tray 31 is rotated to store or discharge the second traction rope 21.
It preferably, further include movable locking plectrum 34 on the hand-rail type winch assemblies, locking plectrum 34 is caught in biography
In the tooth socket K in one of gear in moving gear group 32, traction rope storage tray 31 is fixed and can not rotate；Locking is dialled
Piece 34 leaves the tooth socket K of gear, and traction rope storage tray 31 can be rotated.
Preferably, hand-rail type winch assemblies are mounted on the inner wall of tunnel escape well, at this time in tunnel escape well
Fixed frame 35 is also equipped on wall, traction rope storage tray 31 and driving gear set 32 are mounted in fixed frame 35, hand component 33
Positioned at the outside of fixed frame 35.Traction rope storage tray 31 and driving gear set 32 are mounted on tunnel escape well by fixed frame 35
Inner wall on.And hand component 33 is located at the outside of fixed frame 35, can grasp convenient for users to directly passing through the hand component 33
Make hand tractor 30.
Preferably, it is equipped with coupling spindle 36 on fixed frame 35, locks 34 sets of plectrum on coupling spindle 36.
More specifically, driving gear set 32 include pinion gear 321, train of reduction gears 322 and with traction rope storage tray 31
Co-axially fixed gear wheel 323, pinion gear 321 are engaged with train of reduction gears 322, and train of reduction gears 322 is nibbled with gear wheel 323
It closes.Said gear group, which is formed by conventional gears group 32, can effectively reduce used power when user's hand component 33 of shake
Gas.The specific structure of train of reduction gears 322 is the prior art, and those of ordinary skill in the art are easy to get, thus this is not repeated.
Specifically, as shown in Fig. 1, Fig. 3 and Fig. 5, under first state, extracting the locking being stuck in 321 tooth socket K of pinion gear
Plectrum 34 can be rotated traction rope storage tray 31；Shaking hand component 33 rotates traction rope storage tray 31, by the second traction rope
10 releases are to a certain degree, so as to not apply external force to clump weight 200 with the second traction rope 10, the clump weight 200 can at this time
It gives the first traction rope 10 1 active forces, makes the connecting pin end b of 10 pull lever component 400 of the first traction rope, so that lever group
400 stress of part finally opens the well lid 100 of tunnel escape well.Then locking plectrum 34 is caught in the tooth socket of pinion gear 321 again
In K, keep hand tractor 30 locked, well lid 100 is kept it turned on.400 stress of lever assembly is so that well lid 100 is opened
Specific technical solution, had disclosed in the patent that publication No. is CN108104173A, thus this is not repeated.
Under second state, as shown in figs. 2,4 and 6, locking plectrum 34 leaves the tooth socket K of pinion gear 321, makes traction rope
Storage tray 31 can be rotated；Shaking hand component 33 makes the rotation of traction rope storage tray 31 to store the second traction rope 21, and at this time the
Two traction ropes 21 apply a upward active force to clump weight 200, to eliminate clump weight 200 to the effect of the first traction rope 10
Power, the first traction rope 10 be applied to the pulling force on the connecting pin b of fan shape component disappearance, then well lid 100 lever assembly 400 from
It is closed under the action of weight.Then locking plectrum 34 is caught in the tooth socket K of pinion gear 321, keeps hand tractor 30 locked, well
Lid 100 remains off.
Above-mentioned hand-rail type winch assemblies are mounted on the inner wall of tunnel escape well, or are mounted on the road surface in tunnel.Work as hand
When the formula winch assemblies of shaking are mounted on road surface, after escape personnel enters tunnel internal, artificially apply an active force to well lid 100
So that well lid 100 is closed, and locking mechanism is installed on well lid 100, so that well lid 100 maintains the lock status.It is mounted on tunnel
When escaping on the inner wall of well, escape personnel can be first in other channel operation hand tractor to open the well lid 100.
Preferably, it is set on the roof of escape well there are two fixed pulley 302 and the cooperation of hand tractor 30, two fixed sliding
Take turns 302 spaced apart, the second traction rope 21 drawn from clump weight 200 after two fixed pulleys 302 with hand around leading
Lead device 30 connects.
Escape manhole mounting structure in tunnel provided by the present invention and tunnel escape well are described in detail above, this
Apply that a specific example illustrates the principle and implementation of the invention in text, the explanation of above example is only intended to
Help understands the present invention and core concept.It should be pointed out that for those skilled in the art, not departing from this
, can be with several improvements and modifications are made to the present invention under the premise of inventive principle, these improvement and modification also fall into the present invention
In scope of protection of the claims.
