It is inserted into well lid hole 2 in use, user will tilt device 8, then makes tilting device 8 will by swinging connecting rod 3
Manhole cover body 1 sticks up pine, and then user will tilt device 8 and remove in well lid hole 2, and user again takes attachment device 5 from connecting rod 3
Under, then according to the position in the two well lid holes 2 in left and right in manhole cover body 1, attachment device 5 is hung over into corresponding annular groove 4 respectively
Interior, then user moves down connecting rod 3, and connecting rod 3, which moves down, can be such that attachment device 5 moves down, attachment device 5
Moving down can be inserted into T-bar 7 in well lid hole 2 by iron chains 6, and subsequent user rotates T-bar 7 by attachment device 5
90 degree, T-bar 7 rotates 90 degree and can not be overlapped with well lid hole 2, and then user moves up connecting rod 3, so can be by well lid
Ontology 1 takes out, and sticks up manhole cover body 1 out from iron rod is held without user, and then can reduce the labor intensity of user, and can
The efficiency that well lid is opened is improved, after manhole cover body 1 is taken out, manhole cover body 1 is placed on notch plate by user, and subsequent user is logical
Crossing attachment device 5 makes T-bar 7 rotate 90 degree, is overlapped T-bar 7 with well lid hole 2, then user, which moves up connecting rod 3, makes T
Shape bar 7 removes in well lid hole 2.
When needing the position to T-bar 7 to be adjusted, user moves up hook 51, and hook 51 moves upwardly through
Connecting rod 3 and kelly 52 can be such that guide sleeve 53 moves down, and the first spring 54 is upheld therewith, and subsequent user is by hook 51 from annular
It is removed in slot 4, while kelly 52 is fixed in user, then user hangs over hook 51 in corresponding annular groove 4, and unclamps
Kelly 52 can make kelly 52 be swung up reset, can so prevent to well lid under the action of the first 54 elastic force of spring
Ontology 1 is lifted up, and hook 51, which removes, to be lifted to manhole cover body 1 and bring inconvenience in annular groove 4, when need by manhole cover body 1 to
On when lifting, user makes rotary joint 56 rotate 90 degree, and rotary joint 56, which rotates 90 degree and passes through iron chains 6, can make the rotation of T-bar 7
90 degree, so user can be facilitated to be lifted up manhole cover body 1, when needing to take out T-bar 7 out of well lid hole 2, user
Rotary joint 56 is set to rotate 90 degree, so as to reset the rotation of T-bar 7, subsequently moving up connecting rod 3 removes T-bar 7
In well lid hole 2.
When needing to stick up pine to manhole cover body 1, user takes out lid 85 out of slot 82, and subsequent user, which is moved to the left, to push away
Bar 86, push rod 86, which is moved to the left, can be such that inserted link 83 is moved to the left, inserted link 83 be moved to the left can make fin 84 remove to the left insert
In slot 82, after inserted link 83 is moved to the left suitable position, push rod 86 is swung forward and is caught in arcuate socket 87 by user, such energy
Enough fixed to fin 84, so as to prevent when sticking up pine to manhole cover body 1, push rod 86, which is moved left and right, sticks up pine to manhole cover body 1
It counteracts, manhole cover body 1 is stuck up pine by fin 84 by subsequent user, and after manhole cover body 1 sticks up pine, user swings backward push rod
86, subsequent user moves right the reset of push rod 86, and push rod 86 moves right, and that fin 84 can be made be inserted into the right by inserted link 83 is slotting
In slot 82, after fin 84 is inserted into slot 82 to the right, user resets lid 85.
When needing to stick up pine to manhole cover body 1 using fin 84, user rotates backward the first L shape bar 12, the first L shape bar 12
Rotating backward can be such that annulus 10 rotates clockwise, and second spring 11 is compressed therewith, can so release the fixation to push rod 86,
Subsequent user is moved to the left push rod 86, and when not needing to stick up pine to manhole cover body 1 using fin 84, user, which moves right, to be pushed away
Bar 86 resets, and then unclamps the first L shape bar 12, can make the first L shape bar 12 to Forward under the action of 11 elastic force of second spring
Dynamic reset fixes push rod 86, can so prevent when being lifted up to manhole cover body 1, push rod 86, which moves left and right, gives well lid sheet
Body 1, which is lifted up, to bring inconvenience.
When needing is caught in push rod 86 in arcuate socket 87, user pulls the 2nd L shape bar 133 to remove arcuate socket 87 to the left
Interior, third spring 134 is upheld therewith, and push rod 86 is caught in arcuate socket 87 by subsequent user, and unclamps the 2nd L shape bar 133, the
Under the action of three springs, 134 elastic force 2nd L shape bar 133 can be caught in the right in arcuate socket 87, so can to push rod 86 into
Capable to fix, so as to prevent when sticking up pine to manhole cover body 1, the shaking of push rod 86 sticks up pine to manhole cover body 1 and causes to hinder, when need
When releasing the fixation to push rod 86, user pulls the 2nd L shape bar 133 to remove in arcuate socket 87 to the left, and third spring 134 is therewith
It upholds, subsequent user removes push rod 86 in arcuate socket 87, and unclamps the 2nd L shape bar 133.
When not needing using the present invention, the downward arch of a swing bar 142 of user opens snap ring 141, the 4th spring 143 with
Compression, subsequent user by the iron chains 6 in left side be put into right side snap ring 141 in, and by the iron chains on right side 6 be put into left side snap ring
In 141, curved rod 142 is then unclamped, curved rod 142 can be made to move up reset under the action of the 4th 143 elastic force of spring
Snap ring 141 is closed, iron chains 6 can so be limited, so as to facilitate the mobile present invention of user, when needs use this
When invention, the downward arch of a swing bar 142 of user opens snap ring 141, and iron chains 6 is fallen downwards therewith, and the 4th spring 143 is pressed therewith
Contracting, subsequent user unclamp curved rod 142.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
