Embodiment
The embodiment of technical solution of the present invention is described in detail below in conjunction with accompanying drawing.Following examples are only used for
Clearly illustrate technical scheme, therefore be only used as example, and the protection model of the present invention can not be limited with this
Enclose.
As shown in figures 2-6, the present invention provides a kind of pipe gallery escape well well lid, and it includes lid 1 and driver 2.
Lid 1 is rotatably located at the upper end of the walling crib 200 of the escape well 100, the well head for covering the escape well 100；Driving
Device 2 includes outer barrel 21 and the slidably expansion link 22 in the outer barrel 21, and the outer barrel 21 is articulated with institute through grillage 300
On the inwall for stating walling crib 200, it is rotatably connected between the expansion link 22 and the lid 1, for driving 1 turn of the lid
It is dynamic, so as to cover or open the well head.
In the embodiment, lid 1 is columnar structured, and its edge is articulated with the periphery wall of walling crib 200 at well head, is made
Obtaining lid 1 can realize that lid 1 is overturn around the rotation of its jointed shaft 400, so as to be covered on well head or open well head.In lid
The inwall of one end relative with its hinged end of body 1 is provided with handle 11, is promoted for operating personnel from the inside of escape well 100
The lid 1.
Connecting rod 3, one end of the connecting rod 3 and the lid 1 are provided between the expansion link 22 and the well lid
Inwall is connected, for example welding or mode connects for screw, and the termination of the other end and the expansion link 22 is hinged.Preferably, institute
Connecting rod 3 is stated for arc structure, and from its hinged end with the expansion link 22 to its connection end with the inwall of lid 1
It is gradually distance from the rotating shaft of the lid 1.So so that the fixing point of inner connecting rod 3 and the inwall of lid 1 is away from lid 1 and walling crib
The jointed shaft 400 of 200 outer walls, so as in 2 open manhole cover of driver, realize less unlatching moment.
Pipe gallery escape well also includes locating rod 4 with well lid, and the expansion link is fixed in one end of the locating rod 4
On 22, the other end is slidably coupled on the outer barrel 21.Specifically, outer barrel 21 and the diameter parallel of locating rod 4 are set, positioning
The first link of one end 51 of bar 4 is fixed on the end head of expansion link 22, the afterbody of outer barrel 21, i.e. lower end is fixedly connected with second
Link 52, the other end of expansion link 22 is inserted on the second link 52, and can be slided with respect to the second link 52.
The number of the driver 2 is two, and two drivers 2 are symmetrically set in the both sides of wellbore centre line.
In the embodiment, driver 2 is electric pushrod.Certainly, the particular type of driver 2 is not limited to electric pushrod,
Can be pneumatic cylinder or hydraulic cylinder etc..
The upper end of outer barrel 21 is fixed with the first journey controller 71 through first support 61, and the lower end of outer barrel 21 is through second support
62 are fixed with the second journey controller 72.The journey controller 72 of first journey controller 71 and second is respectively used to control institute
The out reach and retraction distance of locating rod 4 are stated, so as to control the stroke of the expansion link 22.Specifically, the He of first support 61
Second support 62 can be steel plate, and it can be fixedly connected on the outer wall of outer barrel 21 through screw or welding manner.When expansion link 22
It is overhanging, predetermined angle is gone to by being overthrown on lid 1, i.e., after lid 1 is opened completely, the first journey controller 71 detects locating rod
4 out reach, so indirect detection to the out reach of expansion link 22 to reach predeterminated position, the first journey controller 71 to
Control room sender, after control room judges through analysis, sends the instruction for powering off driver 2, so that controller is powered off, stretches
Bar 22 stops overhanging.The principle for the stroke that second controller control expansion link 22 is retracted is identical with this, can specifically compare the
One controller controls the analysis of the out reach of expansion link 22, and here is omitted.
Further, the lower end of the outer barrel 21 of the electric pushrod be provided with manual setter 8, the manual setter 8 with it is described
Expansion link 22 is connected, in the electric pushrod no power, to the driven by shaking of expansion link 22.
Further, in addition to Arming Assembly, the Arming Assembly includes support bar 91, is plugged on the support bar 91
Safety plug 92, and the key seat 93 on the inwall of lid 1.Wherein, one end of the support bar 91 is articulated with described
The upper end of the inwall of walling crib 200, the other end is free end, and safety plug 92, the support bar 91, safety plug 92 and pin are plugged with thereon
Seat 93 is used cooperatively.With reference to Fig. 5-6, when maintenance, support bar 91 is rotated and turned at key seat 93, and by the support bar 91
Free end be plugged in through the safety plug 92 on the key seat 93, so as to realize the support to the lid 1.In this way, realizing
To the dual support of lid 1, even if driver 2 breaks down, it is impossible to support lid 1, Arming Assembly remains able to realize pair
The mechanical support of lid 1, it is therefore prevented that operating personnel is safe because lid 1 is dashed forward when entering upkeep operation in escape well 100 through well head
So tumble and cause security incident.The well lid can realize more than 90 ° of opening, in order to upkeep operation.
On the inwall of walling crib 200 be provided with control button 10, for control driver 2 start and stop and its motor it is positive and negative
Turn, so as to control opening or the closing of lid 1.
In Fig. 4, lid 1 is open mode, but Arming Assembly not enabled, and now operating personnel can enter in well, and press
Control button 10, the motor (not shown) reversion of electric pushrod, makes expansion link 22 retract, so as to realize the closing to lid 1.
In Fig. 3, lid 1 is closed mode, and the operating personnel in escape well 100 can press control button 10 so that electric pushrod
Rotate forward, so as to realize the opening of lid 1.And the lid 1 being closed, because the mechanical locking of electric pushrod is acted on, outside
Portion personnel by force can not open lid 1, so as to prevent the destruction to pipe gallery.The keying of lid 1 also can be by control room
Remotely, centralized Control.
Pipe gallery escape well in the application is stable with well lid reliable transmission, the locking position assurance safety of lid 1.Separately
Outside, its simple in construction, small repair and maintenance amount, safe antitheft, be easy to management, the conveniently opening and closing of lid 1.
