Determining tooth 32, third fixes tooth 32 line alignment centered by the third slideway 31.Also slide on described machine bar 3 and be provided with support set 33,
Support set 33 sliding on the third slideway 31, support set 33 both sides are provided with fixes, with described third, the third buckle 35 that tooth 32 interfixes.
The third rotating shaft 34 it is provided with on described support set 33.It is provided with support arm 6 between described the third rotating shaft 34 and fourth rotating shaft 54.
Described counter-jib 4 bottom is provided with dismountable counter-balanced carriage 8, and counter-balanced carriage 8 includes being arranged on counter-jib 4
Counterweight rotating shaft 81, counterweight rotating shaft 81 rotates and is provided with connection strap 82, and connection strap 82 connects counterweight basket 83.Described lifting arm 5
Top is provided with ground jack 9, and ground jack 9 includes the coiler 91 being arranged on lifting arm 5 top, is placed with stay cord in coiler 91
92, stay cord 92 top is provided with dismountable drag hook 93.
It is provided with several foldings so that described machine bar 3 is the distribution of center of circle uniform circular and activity on described base 1 to prop up
Dagger 7, described base 1 is provided with several breach 12 matched with described folding support post 7.Described folding support
Post 7 includes first folding column 71 and second folding column 72, is provided with folding rotary shaft between described first folding column 71 and second folding column 72
73, described folding rotary shaft 73 is provided with first steady pin 74.Described folding support post 7 end is provided with fixed mechanism, institute
The fixed mechanism stated includes fixed rotating shaft 72, and described fixed rotating shaft 72 is provided with second steady pin 75, described fixed rotating shaft
Dismountable fixing pin 101 or dismountable sucker 103 or dismountable fixing post 102 it is provided with on 72.Described base 1 end
Portion is provided with dismountable universal wheel 11.
When need not work, base 1 is additionally arranged at the bottom universal wheel 11, in order to mobile.Generally speaking in order to keep advancing surely
Fixed with smooth and easy, install 4 universal wheels 11 additional at base 1 bottom even.The receipts accommodating universal wheel 11 can also be set in base 1
Receive groove.Then the fixing device on folding support post 7 is removed, to facilitate folding support post 7 to be retracted on base 1.Fold and prop up
Dagger 7 is fixed by first steady pin 74, and between preventing from advancing, first folding column 71 and second folding column 72 mutually swing.In this state
The present invention can carry out pulling transport, if necessary, it is also possible to installs driving motor in base 1 additional, by driving motor to drive
Universal wheel 11, allows this loop wheel machine automatic moving.When needing to use, first this loop wheel machine is moved to lift by crane position.Because this loop wheel machine is special
Fixed form for different terrain is optimized so that this loop wheel machine is applicable to various landform.It is said that in general, this loop wheel machine moves to
Behind lifting position, put down hydraulic column 13, in order to pull down universal wheel 11.Then unclamp first steady pin 74, allow folding support post 7 pass through
Breach 12 carries out extra fixing outside reaching, subsequently regain hydraulic column 13 and allow base 1 contact ground.Because the folding of this loop wheel machine
Folded support column 7 uniform circular is distributed on base 1, can stretch out arbitrarily to multiple directions, can choose to install adaptation simultaneously
The fixed mechanism of Different Ground type so that this loop wheel machine can be fixed under severe ground environment.The most on the slope,
In order to topple when preventing work, fixing pin 101 can be installed on fixed rotating shaft 72 additional, by fixing pin 101 is inserted into
Subsurface carries out stronger fixing, and this fixing means is also applied for the soft sand ground in soil, mud ground, meadow etc..If
Ground is uneven, and after base 1 is placed, whole loop wheel machine is unstable, it is also possible to is fixed by folding support post 7, allows whole loop wheel machine protect
Hold balance and stability.Because folding support post 7 can install fixing pin 101, sucker 103, fixing post 102 or other all kinds additional
Fixture, as long as having space pedestal for placed 1 and folding support post 7 can being allowed to stretch out, can make this loop wheel machine obtain preferable stabilising surface.
Even level land is placed, as long as allowing folding support post 7 stretch out contact ground will improve the stability of this loop wheel machine, this loop wheel machine can be allowed
Load and stability improve.Certainly, without carrying out the fixing of folding support post 7 when fixing, only fixing by base 1 also it is
Feasible.
After base 1 has been placed, fix according to weight, the height of lifting object, the weight of breeding and the loop wheel machine of lifting object
Stasiofax calculate hoisting moment safety range and optimal hoisting moment, then adjustment arm 4, lifting arm 5 and support arm 6
Between hoisting moment in hoisting moment safety range and closest to optimal hoisting moment.The regulation of counter-jib 4 is mainly passed through
First rotating shaft 39 on machine bar 2, first rotating shaft 39 can be electrically driven (operated) electric rotation shaft.The regulation of lifting arm 5 is mainly by counter-jib 4
On slip cap 43.Between first slideway 41 and slip cap 43 on counter-jib 4 can be chain structure, and driving means is arranged on
In counter-jib 4, allowing slip cap 43 move on first slideway 41 by driving means, the first buckle 45 on slip cap 43 can also be
Automatically controlled, after moving to target location, both can fix tooth 42 with locked first and carry out the fixing of slip cap 43, be arranged on slip cap 43
Second rotating shaft 44 can be electrically driven (operated) electric rotation shaft, second rotating shaft 44 controls the rotation of lifting arm 5.The mobile needs of support arm 6
Fixed cover 53 and support set 33 are carried out simultaneously.Be provided with on lifting arm 5 between second slideway 51 and fixed cover 53 can be chain
Structure, driving means is arranged in lifting arm 5, allows fixed cover 53 move on second slideway 51 by driving means, fixed cover 53
On second buckle 55 can also be automatically controlled, after moving to target location, both can fix tooth 52 with locked second and be fixed set 53
Fixing, the fourth rotating shaft 54 being arranged on fixed cover 53 can be electrically driven (operated) electric rotation shaft, and fourth rotating shaft 54 controls turning of support arm 6
Dynamic.Be provided with on machine bar 3 between third slideway 31 and support set 33 can be chain structure, and driving means is arranged in machine bar 3,
Allowing support set 33 move on the third slideway 31 by driving means, the third buckle 35 on support set 33 can also be automatically controlled, mobile
Behind target location, both can with locked third fix tooth 32 be supported overlapping 33 fixing, the third rotating shaft being arranged on support set 33
34 can be electrically driven (operated) electric rotation shaft, and the third rotating shaft 34 controls the rotation of support arm 6.Package unit is can be very if electricity drives
Readily counter-jib 4, lifting arm 5 and support arm 6 are adjusted.
Counter-jib 4, lifting arm 5 and support arm 6 place breeding after having regulated in counterweight basket 83, it is however generally that counter-balanced carriage
8 is dismountable, dismantles in transit, in use installs.Lifting object has been carried out after completing by all working by ground jack 9
Weight, rotating disk 2 carries out the rotation of machine bar 3.After lifting completes, dismantle counterweight basket 83, pack up folding support post 7, by putting down hydraulic pressure
Post 13, installs universal wheel 11.Then this loop wheel machine just can easily be transported.
