Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of hanging device, weight-balancing device and
Hooking method.
Background technology
Balance weight is one of important composition parts of crane, and which determine crane plays principal characteristic
Energy.In crane hanging component process, need balance weight is assembled, balance weight assembling whether convenient,
It is fast to weigh crane ease of use important indicator.On hoister in large tonnage, balance weight
Mounting system is that hydraulic jack drives the motion of balance weight support to realize assembling.
At present, hoister in large tonnage is the demand meeting different work operating mode to balance weight, the most general
All over using Combined flat weight, this is accomplished by, in crane hanging component process, filling balance weight
Joining, balance weight assembling is the most convenient, fast is to weigh crane ease of use important indicator.
On hoister in large tonnage, balance weight mounting system is the fortune that hydraulic jack drives balance weight support
Dynamic realization is assembled.On hoister in large tonnage there is many asking in the balance weight mounting system of application at present
Topic, as the highest in operation complexity, installation time length, security reliability, hoister in large tonnage full configuration
Narrow space etc. between balance weight bottom surface and vehicle frame during weight.
For the problems referred to above, balance weight support is used to support counterweight block and increase locking dress at present
The mode put can improve the security reliability of hoister in large tonnage balance weight mounting system；And
Use balance weight support to support balance weight overall structure after having mounted, reduce balance weight oil cylinder
Impact, extend oil cylinder life-span.
The counterweight structure of crane most widely used self-jacking type oil cylinder mounting at present has two
Kind, the first scheme is that one group of hydraulic jack hang upside down is fixed on turntable afterbody, utilizes liquid
Cylinder pressure cylinder rod telescopic band dynamic balancing weight body vertical movement, and by regulation hydraulic cylinder cylinder rod to
Under stretch out length, thus realize the location of the combined counterweight body to different-thickness and fixing；The
Two kinds of schemes are that combination balancing pouring weight is positioned over balance weight base plate both sides, and rotation of rotary table aligns,
Hydraulic jack cylinder barrel jack-up balance weight support, passes through two-dimensional positioning system, it is ensured that support and turntable
Fit-up gap, assembled by bearing pin and turntable, cylinder piston rod shrinks and promotes combination type balance
Weight base plate so that it is be connected with rack pin shaft, discharges oil cylinder internal pressure, completes balance weight mounting.
The first scheme, the weight of balance weight has all concentrated in hydraulic cylinder cylinder rod, and has pacified
By the fixed form of the locked fixed balance weight of balanced valve after dress, cause its work overall process liquid
Cylinder pressure will maintain higher pressure, easily produces seal fails, and balance weight declines, and produces
Dangerous.
First scheme, distance limit between tail framework underside and chassis upper surface after turntable,
Balance weight support is positioned on the upside of chassis, sometimes results in turntable and balance during rotation of rotary table
Weight support produces interferes, it is impossible to complete mounting, and secondly, the spacing guide pad of this mounting system is fixed
Position device can not use machine adding method to process with hole, location, downside due to it simultaneously, and size has deviation,
Cannot realize being accurately positioned.
For meeting complete machine axle load and the requirement of road driving standard, by balance weight support and balance weight
Block is designed as dismantled and assembled structure, installs balance weight, balance weight mounting system before crane hanging component
Mounting efficiency and mounting reliability directly affect project progress.So, improve balance weight and hang
The reliability of welding system is that Novel balance heavily mounts systematic research direction with mounting efficiency.
