Embodiment
By reference to one exemplary embodiment, the purpose of this utility model and function and these purposes and function are used for realization
Method will be illustrated.However, the utility model is not limited to one exemplary embodiment as disclosed below；Can be by not
It is realized with form.The essence of specification is only to aid in various equivalent modifications Integrated Understanding the utility model
Detail.Hereinafter, the embodiment of the utility model will be described with reference to the drawings.In the accompanying drawings, identical reference numeral
Represent same or similar component, or same or like step.
The content of the utility model is described in detail with reference to specific embodiment.
In the utility model, the lever support is located at manipulation portion nearside, and the holddown spring is located at the lock
Portion's nearside.Here what is stated is their relative position relations between four, i.e., arranges in the following order：It is the lock section, described
Holddown spring, the lever support and the manipulation portion.
In the utility model, the U-shaped hole of lockhole moves up and down easy to lockhole, realizes slotting with lock tongue (using taper surface)
Enter to coordinate, to contain the error of the generations such as manufacture, assembling.
In the utility model, lock tongue cavity is slotted hole, has position regulating function.
In the utility model, the limited block in bearing cavity, can limit upper bracket movement travel.
In the utility model, holddown spring ensures to promote lever both ends to compress and be bonded with lock tongue, upper bracket respectively.
In a specific embodiment, with reference to figure 1-4, the piping lane manhole cover or intelligent well cover mechanical lock of the utility model
System composition is as follows：Well seat 1 is connected with lockhole 7 by adjusting bolt I 8, due to lockhole 7 have U-shaped hole (slotted hole, as Fig. 3,
Shown in Fig. 4), moved up and down easy to lockhole 7, realize that the insertion with lock tongue 15 (using taper surface) coordinates, to contain manufacture, assembling
Deng the error of generation.Lock tongue cavity 12 is connected 13 with well lid 2 by flange bolt (has the position adjustment work(of above-mentioned slotted hole
Can).Lock tongue 15 loads lock tongue cavity, and lock tongue cavity 12 is connected with flange I 10 by flange bolt II 9, and in flange I 10 and lock
Load resetting spring II 11 between tongue 15.It is connected through a screw thread between bearing cavity 16 and well lid 2, bearing cavity 16 installs compression successively
Spring III 17 (avoiding transport, the steel body impact of installation process), upper bracket 18, and be connected to flange II 19 by screw thread
On bearing cavity 16, bearing cavity 16 is built-in limited block 20, to limit 18 movement travel of upper bracket.Lever 3 is promoted to pass through spiral shell
Line is installed on lever support 5, and installs holddown spring 4 between lever 3 and well lid 2 additional promoting, it is ensured that promotes 3 both ends of lever difference
Compress and be bonded with lock tongue 15, upper bracket 18.
In a specific embodiment, the piping lane manhole cover of the utility model or intelligent well cover mechanical lock system operation stream
Journey can be divided into next stage (with reference to shown in Fig. 1-6)：
(1) (in sealing contact) is closed
Well lid 2 is contacted with well seat 1 under gravity at the beginning of closure, and pressure between the two is only from 2 gravity of well lid.
In 2 dropping process of well lid, its decrease speed be more than manipulation portion in the power original paper such as retraction of Electrohydraulic push rod 6 speed, therefore on
Bearing 18 should be bonded with limited block 20, it is ensured that lock tongue 15 is retracted in lock tongue cavity 12, so as to avoid because lock tongue 15 and well seat are convex
The phenomenon that well lid 2 cannot be bonded with well seat 1 caused by platform interference produces.
(2) closure (sealing compresses)
On the basis of closing (in sealing contact) process in (1), Electrohydraulic push rod (or other power original papers) 6 continues to bounce back, will
Upper bracket 18 moves down, and promotes lever 3 its right end will be made to be moved down with upper bracket 18 under the action of holddown spring, and promotes
3 left end of lever moves up, and promotes lock tongue inclined plate 14 to move to left, is stretched out so as to fulfill lock tongue 15, until Electrohydraulic push rod (or other power are former
Part) 6 movements stop, and relative position is as shown in Figure 3,4 between lock tongue 15 and lockhole 7 at this time.Fig. 5 is the another of lock tongue 15 and lockhole 7
Form, at this time lockhole be changed into baffle or block form, have cooperation inclined-plane between lock tongue and block, to ensure that lock tongue smoothly stretches into block
Lower part；8 show adjustment bolt I.
(3) (in sealing contact) is opened
Opening process is actually the inverse process for completing (2) closure (sealing compresses) process.Electrohydraulic push rod (or other power
Original paper) 6 start to stretch out, upper bracket 18 will move up drive and promote 3 right end of lever to move up at this time, and then promote 3 left end of lever to move down,
Lock tongue 15 moves to right under the effect of resetting spring II 11, bounces back so as to fulfill lock tongue 15, until upper bracket 18 is contacted with limited block 20,
Relative position unlocks as shown in Figure 1, completing mechanical lock between lock tongue 15 and lockhole 7 at this time.
(4) (well lid is separated with well seat) is opened
On the basis of opening (in sealing contact) process in (3), Electrohydraulic push rod (or other power original papers) 6 continues to stretch, on
Bearing 18 rotates unlatching by well lid 2 is dragged.
Above-mentioned piping lane manhole cover or the action of intelligent well cover open and close, can be referring to Fig. 7.
The piping lane manhole cover or intelligent well cover external force of the utility model are difficult to open, and play good anti-theft feature, such as Fig. 1
It is shown.
The piping lane manhole cover or intelligent well cover of the utility model open facility inside piping lane or inside well：I is due to machinery
Lock with internal motivation original paper hydraulic cylinder (Electrohydraulic push rod, electric putter etc.) by promoting lever 3 to associate, mechanical lock lock tongue 15 act by
Hydraulic cylinder action control, realizes the automation that lock tongue 15 acts, is manipulated without other power；Ii lock tongues 15 are in normally open,
I.e. under the action of resetting spring, lock tongue 15 is in 12 state of retraction lock tongue cavity, as shown in Figure 1, reducing due to mechanical lock
Failure and the probability for causing the appearance that well lid can not open.
The piping lane manhole cover of the utility model or the mechanical lock transmission system of intelligent well cover have stroke enlarging function, such as scheme
2nd, shown in Fig. 3, Fig. 6, the ratio between lock tongue 15 and 18 stroke of upper bracket are 3-4, preferably 3.5, i.e., d/d=3.5 times, pass through relevant parameter
Adjustment, realizes that lock tongue stroke is flexibly changed, to contain the manufacture of manhole cover or intelligent well cover, rigging error, easy to debug and pacify
Dress.
The piping lane manhole cover of the utility model or the mechanism of intelligent well cover are compact, easy to system layout：Due to upper bracket 18
Stroke is small, causes bearing cavity 16 compact-sized, easy to be machined manufacture and integral layout.
It should be noted that in addition to the above embodiment, the utility model also has a lot of other embodiment party certainly
Formula, the explanation of the utility model disclosed here and practice are merely illustrative, and above-described is only the utility model
Preferred embodiment, for those of ordinary skill in the art, on the premise of the utility model principle is not departed from, may be used also
To make several modifications and improvements, these also should be regarded as belonging to the scope of protection of the utility model.
