To improve efficiency of construction, laborsaving can be suitable for the boom hoisting of various working.
For achieving the above object, the technical solution adopted in the utility model is: a kind of be suitable for various working rise
Device for hoisting, including lifting parts and hold assembly, it is characterised in that lifting parts include lifting rod and bottom
Hoisting frame, lifting rod upper end is provided with connecting portion, and described hold assembly includes the torr being symmetricly set on hoisting frame both sides
Plate, supporting plate outer end is provided with subiculum tooth, and the lower surface of described subiculum tooth has the gradient, and each subiculum tooth is all by even
Fishplate bar is connected with upper clamp, is connected by compression spring between two supporting plates, and supporting plate and compression spring are externally provided with set
Cylinder, described supporting plate can be slided in sleeve by the guiding mechanism set in sleeve, and it is right that described hoisting frame lower end is provided with
The briar tooth claimed.
Preferably, described connecting portion is the mounting ring that may pass through quick-release latch.
Preferably, described connecting plate is provided with multiple through hole, and bolt passes through hole by subiculum 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. subiculum tooth, clamp on 11., 12. connecting plates, 13. through holes, 14. briar tooths, 20. peaces
Dress ring, 31. supporting plates, 32. compression springs, 33. sleeves, 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 lifting rod 41 upper end is provided with connecting portion；Clamping
Parts include being symmetricly set on lifting parts both sides supporting plate 31, and supporting plate 31 outer end is provided with subiculum tooth 10, described under
The lower surface of torr tooth 10 has the gradient, and each subiculum tooth 10 is all connected with upper clamp 11 by connecting plate 12,
Being connected by compression spring 32 between two supporting plates 31, supporting plate 31 and compression spring 32 are externally provided with sleeve 33,
Described supporting plate 31 can be slided in sleeve 33 by the guiding mechanism set in sleeve 33, and hoisting frame lower end is provided with
Symmetrical briar 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 torr tooth 10 is more than the diameter of catch pit port, the when that hold assembly being passed down through catch pit port, subiculum
The lower surface edge of tooth 10 contacts with catch pit port, and two subiculum teeth 10 are by the extruding force of catch pit port, along with lifting
Fixture entirety moves gradually downward, and the distance between two subiculum teeth 10 is gradually compressed reduction, sleeve 33
In two supporting plates 31 between compression spring 32 be squeezed contraction, when stone tongs entirety continues to move down
During to two subiculum tooth 10 outer end contact Seat for manhole cover lower surfaces, two supporting plate 31 returning in compression spring 32
Returning to initial position under bullet effect, two subiculum teeth 10 just block Seat for manhole cover lower edge, go up clamp simultaneously
11 upper limbs blocking inspection well cover mouth, now host service function promotes stone tongs, can be by Seat for manhole cover and milling
After annular bituminous concrete expense material remove.Cleaning recrement, pads recovery well limit Colophonium by levelling to well head and road surface
And be compacted, complete well head repair.When the diameter of inspection well cover mouth is too small, two subiculum teeth 10 can not stretch into
During catch pit port, first tilt to stretch into catch pit port, after blocking Seat for manhole cover lower edge, then by stone tongs by briar tooth 14
Being arranged on main frame swing arm, the operation of main frame swing arm promotes stone tongs, can be by the ring after Seat for manhole cover and milling
Shape bituminous concrete expense material removes.
Preferably, described connecting portion is the mounting ring 20 that may pass through quick-release latch, during installation, quickly discharges
Stone tongs, through mounting ring 20, is quickly installed on main frame by pin, and mounting ring 20 makes dismounting and changes 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, subiculum tooth 10 and upper clamp 11 are separately fixed on connecting plate 12 by bolt through through hole 13.
