Auxiliary hydraulic cylinder 2 provides support.Interior supporting leg is conveniently folded and overlayed by the width of interior supporting leg 301 less than the width of outer supporting leg 302
In outer supporting leg.The head of the piston rod of auxiliary hydraulic cylinder 2 is provided with a roller 4, and the piston rod for facilitating auxiliary hydraulic cylinder 2 is being folded
Roll on the inclined-plane that sectional shelf-unit 3 is formed when rising.The piston rod of anti-dumping hydraulic cylinder 1 is bulb type piston rod, facilitates it sliding
Slide in groove 8.A tray 5 is installed in the lower section of anti-dumping hydraulic cylinder 1 on crane mainframe, when anti-dumping hydraulic cylinder 1 packs up level
It is that anti-dumping hydraulic cylinder 1 provides support when being placed on crane mainframe.
The crane of the present embodiment includes gantry body 6, and on the arm support 7 of gantry body 6 chute 8, lifting are provided with
Above-mentioned crane arm support anti-squat system is installed on the crane mainframe of machine body 6.When arm support 7 rises, anti-dumping hydraulic cylinder 1
Piston rod stretch in chute 8 and provide support to arm support 7.More preferably, two chutes 8, crane are installed side by side on arm support 7
Two sets of preventing backward tilting of arm support devices for matching with two positions of chute 8 respectively are installed side by side on main frame.Thus, using two sets
Preventing backward tilting of arm support device can provide arm support 7 preferably support, more stable, reliable.
The principle of the preventing backward tilting of arm support device and crane is as follows：
（1）When in original state：Auxiliary hydraulic cylinder 2 is connected by bolt with anti-dumping hydraulic cylinder 1, anti-dumping hydraulic cylinder 1
It is hinged with the hinge ear on crane mainframe, the front end of anti-dumping hydraulic cylinder 1 is placed on tray 5, Fold-Combined support 3 withdraws and keeps flat
On crane mainframe.Fold-Combined support 3 is folded and withdrawn, and interior supporting leg 301 is hinged in interior supporting leg fixed seat 303, interior supporting leg
301 and outer supporting leg 302 by through fold dowel hole 305 bearing pin fixation in outer supporting leg fixed seat 304.
（2）When preventing backward tilting of arm support device is risen：The bearing pin in dowel hole 305 will be folded first to extract, and will fold group
The interior supporting leg 301 and outer supporting leg 302 for closing support 3 is opened, then one end of outer supporting leg 302 is hinged in outer supporting leg fixed seat 304,
Fold-Combined support 3 is risen and forms inclined-plane；Then the piston rod of auxiliary hydraulic cylinder 2 stretches out, and the roller 4 of piston rod head is along folding
The inclined-plane of folded sectional shelf-unit 3 scrolls up, and drives anti-dumping hydraulic cylinder 1 to be lifted up；Simultaneously the piston rod of anti-dumping hydraulic cylinder 1 is stretched
Go out, the arm support 7 of crane is lifted, the piston rod head of anti-dumping hydraulic cylinder 1 is fallen in chute 8, continue cantilever lifting, anti-dumping hydraulic cylinder 1
Piston rod head along the upward sliding of chute 8, when the piston rod head of anti-dumping hydraulic cylinder 1 slides into end in chute 8, with
Arm support 7 and continue cantilever lifting, the piston rod of anti-dumping hydraulic cylinder 1 is compressed withdrawal, until arm support 7 reaches crane job position.
（3）After the completion of crane work：Arm support 7 is put down, the piston rod of anti-dumping hydraulic cylinder 1 synchronously extend out to most long position,
Subsequently, the piston rod of anti-dumping hydraulic cylinder 1 progressively exits chute 8, auxiliary when the piston rod of anti-dumping hydraulic cylinder 1 exits chute 8 completely
The piston rod head roller 4 for helping hydraulic cylinder 2 falls on the inclined-plane of Fold-Combined support 3, at this moment withdraws the piston of auxiliary hydraulic cylinder 2
Bar, anti-dumping hydraulic cylinder 1 progressively falls after rise, until anti-dumping hydraulic cylinder 1 and auxiliary hydraulic cylinder 2 return to initial position, will finally fold group
Close support 3 to withdraw.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
