Axis, when the cutter head of electric wrench is the casing of square inner bore, the electronic interconnecting piece 751 should be square protruding.It is pulled electronic
The cutter head of hand is inserted into the electronic interconnecting piece 751, the rotation of screw rod 74 can be lifted by crane described in fast driving after starting, to realize fast
Speed lifting, there are positive and negative rotation switching, this sample embodiments, and quick set-down equally can be achieved for certain electric wrench.The bull stick is radial
Mounting hole 752 is illustrated as through-hole, and can be inserted into rotation operating stick can be inconvenient to grasp by manually being driven in the electric wrench
When vertical, using manually carrying out some operations.The rotation operating stick is one of common tool of maintenance personnel, no longer superfluous herein
It states.In addition, gravity can apply biggish resistance to the screw thread on the lifting screw rod 74, so directly because 11 weight of well lid is big
The driving lifting screw rod 74 is connect, required force can be bigger, therefore the present embodiment increases the lifting speed changer 73, though
It reduces a part and promotes speed, but greatly reduce required force, driven convenient for electric wrench.
Well lid hanging device 9 is installed, the well lid hanging device 9 includes at least two connections on the lower force seat 8
Mounting ring 91 on the lower force seat 8, mounting ring 91 described in the present embodiment set there are two and two mounting rings 91 be
The both ends of the lower guiding axis 81 are connected to, are connected separately with hitch bar 92, the hitch bar on the mounting ring 91
92 bottom end is connected with hook.The present embodiment is illustrated with circular well lid 11, and two through holes, ability are arranged on well lid 11
Field technique personnel will recognize, for the well lid 11 set there are four through hole, the present embodiment can be by increasing the mounting
The mode of bar 92 and the hook carry out using, can also be applied certainly for rectangular 11 the present embodiment of well lid, these
The structure change of the well lid hanging device 9 all should be within that scope of the present invention.
The application method of the present embodiment are as follows: the present embodiment is moved to kiln Jing1Chu, the two lifting stringers 21 are rested against
Kiln well 1 if two 21 width of the lifting stringer are excessive or too small, preferentially adjusts its spacing along upper；Described in being adjusted after seating against
242 expanded angle of swing rod is leveled, the telescopic outrigger 248 is also transferred to appropriate length, until the buttress 249 is effectively propped up
Support, the lifting armstand 4 is erected, manually pulls the transposition drawstring 34 that the well lid hanging device 9 is made to be located at well lid 11 just
The cutter head of electric wrench is inserted into the electronic interconnecting piece 751, declines the well lid hanging device 9 after unlatching by top, until
Two hooks can hook two perforation hole sites of well lid 11, electric wrench is adjusted to reversion, well lid 11 is lifted, waits and hang
Certain altitude is played, electric wrench is stopped and is extracted, the transposition drawstring 34 is manually pulled, makes well lid 11 far from kiln well 1, safeguards people
Member can carry out underground maintenance work, and the transposition drawstring 34 is prevented at the same time as the structure to the lifting slide 3 binding positioning
Only it slides back to kiln Jing1Chu, causes unexpected generation；When well lid 11 need to be put back to, need to only be carried out by opposite action.
The present embodiment is by the upper connecting rod 64 and the lower link 65, to the lifting screw rod 74 and its connection structure shape
Stablize strut angle support at three shapes, structure is relatively reliable, can effectively avoid 11 weight bring malformation of well lid；Support is reliable
Property raising facilitate the lifting screw rod 74 to borrow the power of electric wrench, can accelerate lifting process, improve lifting efficiency.This reality
It is easy to operate to apply example, it is convenient to lift by crane, and can be widely used for the kiln well lid slinging work in each field, has biggish economic value and society
It can be worth.
The above shows and describes the basic principle, main features and advantages of the invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
