To the deformation force of column, so as to reduce the deformation of column, the stability of column is improved, makes the operating mode ring that a functional adaptation is more complicated
Border；In the case of equal equipment and load, column and diagonal brace can be designed to more light and handy, reduction is designed and manufactured as
This.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：
A kind of mounting structure of anti-stake machine column deformation is provided, is specifically included：
Equipment (load), column, steel wire rope, the diagonal brace oil cylinder being arranged on diagonal brace, rise draw oil cylinder, fuselage platform；
The equipment is arranged at the one side of column；Diagonal brace oil cylinder is arranged at the offside of column, the upper end of diagonal brace oil cylinder
It is connected with the top of column, lower end is connected with fuselage platform；Diagonal brace oil cylinder includes diagonal brace oil cylinder one and diagonal brace oil cylinder two, diagonal brace
The lower end of oil cylinder one and diagonal brace oil cylinder two is separately positioned on fuselage platform both sides；
The column is mounted on the front end of fuselage platform；
Described rise draws one end of oil cylinder to be fixed on fuselage platform, and the other end is fixed by steel wire rope and column upper end to be connected
It connects.
Further,
Described rise draws oil cylinder as one or more parallel connections.
Column mainly keeps its working condition by platform and the diagonal brace oil cylinder being connected with platform, and equipment (load) is in work
When making state, equipment can give one power identical with load direction of column, when stem height is higher or equipment is (negative
Carry) it is bigger, the deflection of column is bigger.It is idle in equipment (load), rise and oil cylinder is drawn to be in slight tensioner
State, when stake machine works, after equipment (load) becomes larger, turgor cylinder and steel wire rope can generate one it is opposite with deformation force
Pulling force, to resist the deformation that equipment (load) brings column.
The utility model also provides the hydraulic control system of above-mentioned anti-stake machine column deformation mounting structure, including：
Shuttle valve group rises and draws oil cylinder, balanced valve, overflow valve, valve group one, valve group two, valve group three, diagonal brace oil cylinder one and diagonal brace oil
Cylinder two；

Cylinder two；
The diagonal brace oil cylinder one, diagonal brace oil cylinder two and the drawing oil cylinder that rises are equipped with big chamber and small chamber, diagonal brace oil cylinder one, diagonal brace oil
Big chamber, the small chamber of cylinder one and the drawing oil cylinder that rises are connected by pipeline with shuttle valve group；
The overflow valve, which is connected to rise, draws the small chamber oil inlet pipe of oil cylinder, before balanced valve oil inlet.
Specifically,
The balanced valve is mounted on the small chamber for drawing oil cylinder that rises.
The hydraulic control method of above-mentioned hydraulic control system, specifically comprises the following steps：
The verticality of S1, adjusting post：When stake machine works, it is necessary to keep uprights vertical, the normal of a machine just can guarantee
Construction；Diagonal brace oil cylinder one is controlled by operating valve group two, valve group three controls diagonal brace oil cylinder two, regulates the verticality of column, protects
Uprights vertical is held to ensure a machine normal construction；
After S2, verticality of stand column have adjusted, it will be risen by operating valve group one and draw oil cylinder debugging to steel wire rope tension, this
When risen by the setting of the pressure of regulation relief valve and draw the initial pullup power of oil cylinder；
S3, when in column one side installment work device, column generates the trend towards equipment (load) Direction distortion,
A pulling force can be generated to the steel wire rope for being connected to column offside simultaneously, pulling force is transferred to rise by steel wire rope draws oil cylinder, and rise drawing oil
The small chamber hydraulic oil of cylinder generates the pressure of a resistance column deformation, and the size of the pressure draws the flat of the small chamber of oil cylinder by being mounted on to rise
Weighing apparatus valve regulation.
Further,
The hydraulic control method further includes step：
S4, when the position of stake machine changes, because of ground flat degree difference, it is necessary to readjust the verticality of column；
During readjusting verticality of stand column, the verticality of column is adjusted with reference to step S1, operates diagonal brace oil cylinder, rises and draws oil cylinder certainly
Dynamic unloading after the verticality of column is adjusted, rises by drawing oil cylinder to initial pulled up condition with reference to step S2 debugging；Then step is repeated
S3 carries out hydraulic control adjusting.
Because during verticality of stand column is readjusted, when diagonal brace oil cylinder one and/or diagonal brace oil cylinder two forward extend out
When adjusting verticality of stand column, diagonal brace oil cylinder one and/or diagonal brace oil cylinder two will generate one in column top and (be born with equipment
Carry) the identical power in direction, if risen oil cylinder is drawn to be still in tensioner state, the thrust and the production for the drawing oil cylinder that rises that diagonal brace oil cylinder generates
Raw direction of pull is opposite, it is likely that damages the structure.Diagonal brace oil cylinder is operated in this programme, rises and draws oil cylinder that can unload automatically,
It can be to avoid the damage structure.
Further,
Due to diagonal brace oil cylinder one, diagonal brace oil cylinder two, rise and the large and small chamber of oil cylinder is drawn to be connected by pipeline with shuttle valve group, when
When operating any valve group in valve group one, valve group two and valve group three, the pressure oil of performance loop can all be entered by shuttle valve group
The balanced valve opening for rising and drawing on oil cylinder is installed on, when pressure reaches setting value, balanced valve is opened；Rise and the small chamber of oil cylinder is drawn to pass through
Oil return line is connected with fuel tank.
By above-mentioned connection scheme, when adjusting column, as long as any valve in operation valve group one, valve group two and valve group three
During group, balanced valve can automatically open unloading, it is no longer necessary to which operation, which is risen, draws oil cylinder unloading balanced valve, can improve the safety system of operation
Number, while simplify operation.
Further,
When pulling force is transferred to rise and draws oil cylinder by steel wire rope in step S3, rise and oil cylinder is drawn to rise in working condition and draw oil cylinder
Small chamber hydraulic oil bears lineoutofservice signal pull；
With the increase of equipment (load), the deformation force identical with equipment direction that column generates increases simultaneously
Add, the pressure for the small chamber for drawing oil cylinder that rises increases, and rises and the pressure of the small chamber of oil cylinder is drawn to be set by the balanced valve being mounted on oil cylinder；Pass through
The pressure of balanced valve is set, adjusts to rise and draws the nominal operation pulling force of oil cylinder, to resist the pressure of column deformation；
Step S3 is so repeated, realizes the hydraulic control to above-mentioned column deformation mounting structure.
The beneficial effects of the utility model：
The utility model adapts to more complicated work condition environment by increasing the stability for rising and drawing oil cylinder that can improve column.
In the case of equal equipment and load, can design column and diagonal brace is more light and handy, reduces cost.
