Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
A kind of well cover opening device, referring to Fig. 1, described device includes：Roller 1, the first bar 2 being connected with the roller 1
And second bar 3, the hook assembly 4 positioned at the end of the second bar 3；
First bar 2 is consistent with the moving direction of the roller 1 with second bar 3, and first bar 2 and institute
Stating between the second bar 3 has default angle.
The utility model embodiment is by hooking well cover opening device and well lid hook assembly 4 in the through hole on well lid
Connection, because hook assembly 4 is located at the end of second bar 3, the second bar 3 is connected with roller 1, while the bar 2 of roller 1 and first
Connection, the first bar 2 and the second bar 3 are consistent with the moving direction of roller 1, i.e. the length direction and roller of the first bar 2 and the second bar 3
1 moving direction is identical, and has default angle between the first bar 2 and the second bar 3, as shown in Fig. 2 by roller 1 on ground
Face as a fulcrum, two ends that the first bar 2 and the second bar 3 are not connected with roller 1 as lever two ends, the one of lever
End is connected by hook assembly 4 with well lid, i.e. one end of the second bar 3 is connected by hook assembly 4 with well lid, the other end of lever
Force side can be then used as, you can exert a force, be used as by roller 1 after fulcrum with one end to the first bar 2, the second bar 3
The position of one end can gradually rise, so that well lid is lifted to the position for leaving ground by the hook assembly 4 being connected with the end,
Finally well lid can be moved to the position of remote well head by the movement of roller 1, and ensure that the safety of workmen.
In order to strengthen the balance of embodiment described above, referring to Fig. 3, the roller 1 is two, the two rollers 1
Connected by transverse axis 5, first bar 2 and second bar 3 are connected in the middle part of the transverse axis 5 between two rollers 1 so that
When being exerted a force to the first bar 2, impetus maintains the balance of stress in the middle part of the crossbeam between roller 1, reduces well lid and opens
Rocking when opening.Also, with second bar 3 at grade, the default angle is 120 ° to first bar 2, this
The setting of individual angle be in order that the location of first bar more meets ergonomics, in the case of 3 levels of the second bar,
Angle between one bar and the second bar is 120 °, is tilted to the direction of workmen so that the operation of workmen is more convenient.
As a kind of preferred scheme, described device also includes：The telescopic T-bar 6 being connected with first bar 2, institute
The tube that the first bar 2 is inner hollow is stated, the T-bar 6 is connected by way of insertion with first bar 2.Referring to Fig. 1
And Fig. 2, when using well cover opening device of the present utility model, T-bar 6 is first inserted to the inside of the first bar 2, due to T-bar 6
For telescopic rod, its T-bar 6 includes outer sleeve 601 and interior bar 602, and the outer sleeve 601 can with the interior bar 602
To relatively move.I.e. in use, its interior bar 602 can be drawn from outer sleeve 601 by pulling T-bar 6
Send as an envoy to the length increase of whole T-bar 6, or promote T-bar 6 to promote interior bar 602 and make whole T-bar 6 in outer sleeve 601
Length reduce, by above-mentioned pulling, promote form adjust T-bar 6 length to make workmen more convenient exert a force.
In embodiment described above, as shown in figures 1 and 3, the hook assembly 4 includes L-shaped suspension hook 401 and institute
State the hinge 402 of the connection of L-shaped suspension hook 401.The hook assembly 4 is two, is uniformly distributed on second bar 3.Due to well
The through hole covered is usually two, then correspondingly set two hook assemblies 4 make it that the stress of well lid is equal on the second bar 3
It is even, cause the movement of suspension hook 401 in the course of the work more flexible by way of hinge 402 is connected with suspension hook 401.
With continued reference to Fig. 1 and Fig. 3, the hook assembly 4 is fixed on second bar 3 by fix bar 7, and described second
The end of bar 3 carries through hole 301, and the fix bar 7 passes through the through hole 301, the hook assembly 4 and the fix bar 7
Two ends are connected, and can consolidate hook assembly 4 by way of a circular hole on hinge 402 to be passed through to the end of fix bar 7
Due to the two ends of the fix bar 7.Length direction of the through hole 301 perpendicular to second bar 3 so that fix bar 7 is passed through
It is vertical with second bar 3 during the through hole 301, therefore hook assembly 4 can be fixed on the both sides of the second bar 3, due to well lid
On through hole generally set two, the arrangement mode of hook assembly 4 is used for corresponding two-by-two with the through hole on well lid, uniformly forces in
Well lid.
Preferably, the fix bar 7 is the expansion link that increasing length is big or reduces, because the size of various well lids differs
The distance between two through holes are also different on sample, well lid, in order that the well cover opening device of the utility model embodiment can be answered
It is big or reduce by the increasing length of fix bar 7 so that 2 suspension hooks positioned at the two ends of fix bar 7 for the well lid of various sizes
The distance between component 4 can also increase or reduce to coordinate the distance between well lid through hole, and fix bar 7 is that expansion link can also
Realized by the way of inner shaft and outside loop bar, and in order that fix bar 7 can be fixed in the second bar 3 not left and right and move
It is dynamic, the middle part of fix bar 7 can be connected with the second bar 3 by modes such as welding.
In addition, carrying loop component 302, the L-shaped suspension hook for placing the hook assembly 4 on second bar 3
401.Referring to Fig. 1, because the whole length of hook assembly 4 is longer, in order to prevent hook assembly 4 from being dropped during movement
On the ground, hook assembly 4 will can be positioned over and second bar 3 in the partial insertion loop component 302 of L-shaped suspension hook 401
Length direction is consistent, and the utility model embodiment does not make specific restriction to loop component 302, and the loop component 302 can be
Annulus.
Above-mentioned all optional technical schemes, can form the alternative embodiment of the disclosure, herein no longer using any combination
Repeat one by one.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
