Road surface, edge is the place of most fragile, owing to the roll off of vehicle is easy to damage.After damage, if needing to change,
Needing to utilize milling machine first to be separated with the cement pavement of periphery by Seat for manhole cover, recycling fixture takes out Seat for manhole cover
And be cut into ring-type cement or bitumen layer waste material about, due to inspection well cover and Seat for manhole cover specification not to the utmost
Identical, it is different size of to adapt to that various sizes of inspection well cover executes the man-hour requirement replacing various sizes of fixture of installation
Catch pit port, dismantles and installs and more bother, and affects efficiency of construction, and time-consuming.
Summary of the invention
The problem existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of multi-functional lifting
Put, strong adaptability, it is possible to adapt to various working, efficiency of construction can be improved, labour can be saved.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Multifunctional hoisting device, bag
Including lifting parts and hold assembly, lifting parts include the hoisting frame of lifting rod and bottom, and described hold assembly sets
Putting on hoisting frame, lifting rod upper end is provided with connecting portion, and described hold assembly includes being symmetricly set on lifting parts
The lower briar tooth of both sides, each lower briar tooth is all connected with upper clamp by connecting plate, by stretching between two lower briar tooths
Shrinking structure connects, and stretching structure includes fixed plate and portable plate, and fixed plate is fixedly mounted on hoisting frame, movable
Plate is located in fixed plate by sliding ledge cover, and the front end of fixed plate and portable plate is connected by extension spring, described hoisting frame
Lower end is provided with torr tooth.
Preferably, described connecting portion is the connection ring that may pass through quick-release latch.
Preferably, described connecting plate is provided with multiple through hole, and bolt passes through hole by lower briar tooth and upper clamp difference
It is fixed on connecting plate.
This utility model can use under various working, it is not necessary to often dismantles, simple in construction, under hoisting frame
Hold assembly and the torr tooth of end are adapted to various Seat for manhole cover, can improve efficiency of construction, save work
This.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 10. descending briar tooth, clamp on 11., 12. connecting plates, 13. through holes, 14. torr teeth, 20. even
T-Ring, 31. fixed plates, 32. portable plates, 33. extension springs, 41. lifting rods, 42. hoisting frames.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
The stone tongs of adjustable well lid milling machine as shown in Figure 1, including lifting parts and hold assembly,
Lifting parts include the hoisting frame 42 of lifting rod 41 and bottom, and hold assembly is arranged on hoisting frame 42, carries
Pull bar 41 upper end is provided with connecting portion；Hold assembly includes the lower briar tooth 10 being symmetricly set on lifting parts both sides,
Each lower briar tooth 10 is all connected with upper clamp 11 by connecting plate 12, and two lower briar tooths 10 pass through stretching structure
Connecting, stretching structure includes fixed plate 31 and portable plate 32, and fixed plate 31 is fixedly mounted on hoisting frame 42,
Portable plate 32 is located in fixed plate 31 by sliding ledge cover, and extension spring is passed through in the front end of fixed plate 31 and portable plate 32
33 connect, and hoisting frame lower end is provided with torr tooth 14.
During construction, stone tongs is fixedly mounted on main frame entirely through connecting portion, after pulling down inspection well cover, main
Stone tongs is suspended in midair above Seat for manhole cover by machine operation, and puts gradually downward, under usual hold assembly that is two
Distance between briar tooth 10 is more than the diameter of catch pit port, the when that hold assembly being passed down through catch pit port, lower hook
The edge of tooth 10 contacts with catch pit port, and two lower briar tooth 10 stress, along with stone tongs entirety is moved gradually downward
Dynamic, the distance between two lower briar tooths 10 is gradually compressed reduction, and portable plate 32 is by slideway and fixed plate
31 relative movements, and extension spring 33 applied elongation, when stone tongs entirety continues to be moved down into two lower briar tooths
During 10 contact Seat for manhole cover lower edge, portable plate 32 returns to initial position under the rebound effect of extension spring 33,
Two lower briar tooths 10 just block Seat for manhole cover lower edge, go up clamp 11 simultaneously and block the upper limb of inspection well cover mouth, this
Time host service function promote stone tongs, can by after Seat for manhole cover and milling annular bituminous concrete take material remove.
Cleaning recrement, pads recovery well limit Colophonium by levelling to well head and road surface and be compacted, completing well head repair.When
The diameter of inspection well cover mouth is too small, when two lower briar tooths 10 can not stretch into catch pit port, first tilts to stretch into by torr tooth 14
Catch pit port, after blocking Seat for manhole cover lower edge, then is arranged on stone tongs on main frame swing arm, and main frame swing arm operates
Promote stone tongs, the annular bituminous concrete after Seat for manhole cover and milling can be taken material and remove.
Preferably, described connecting portion is the connection ring 20 that may pass through quick-release latch, during installation, quickly discharges
Sell through connecting ring 20, stone tongs is quickly installed on main frame, connect ring 20 and make dismounting and change more
Add conveniently.
Further, in order to be adapted to the Seat for manhole cover of multiple different size, connecting plate 12 is provided with multiple
Through hole 13, briar tooth 10 and upper clamp 11 are separately fixed on connecting plate 12 by bolt through through hole 13.
