Description
Technical field
The utility model is related to a kind of for fixing the plate drawing system of auxiliary operating mode, belong to crane technical field.
Background technology
With the quickening of Urbanization in China, economic fast development, the scale of state fundamental construction is increasing, needs
The weight and lifting altitude for the article to be lifted are increasing, and crawler crane increasingly shows its superiority, and crawler type rises
Heavy-duty machine has obtained swift and violent development.It is secondary to be commonly designed installation in order to improve its lifting altitude and work range for crawler crane
Arm operating mode.
After crane arm support generally assembles on ground, by itself luffing ability by arm support cantilever lifting to operating angle.
Horizontal cantilever lifting state, arm support is one long thin press-bending structure, due to the dead weight of arm support, the entire arm support of arm support especially center section
Downward amount of deflection can be generated, initial deformation will be further increased under the arm support axial separation effect generated in luffing power, and cause two
Secondary deformation, so as to increase the structural stress of arm support.Further, arm support length is longer, and arm support weight is heavier, and arm support will have unstability
Danger；To improve the cantilever lifting ability of long-armed operating mode boom system, arm support cantilever lifting security is improved, it usually needs increase waist rope dress
It puts, as shown in Figure 1.
There are still following shortcomings for the prior art：
1. angle is smaller between pulling plate and auxiliary stent after auxiliary, auxiliary stent axial force is larger, otherwise auxiliary stent is selected
More complicated, the heavier-weight that the material or structure of high material are done, cost are larger；
2. after auxiliary near pulling plate and principal arm hinge area（Such as a-quadrant in Fig. 2）, there is stress concentration phenomenon, it is necessary to spy
Different reinforcement processing can increase the arm support weight of principal arm system；
3. during cantilever lifting, angle is smaller between principal arm pulling plate and principal arm system, arm support length more long angle therebetween is smaller, folder
Angle is smaller, and caused arm support axial force is bigger.Arm support can generate a downward amount of deflection during cantilever lifting, due to the effect meeting of waist rope
The angle between principal arm pulling plate and principal arm is made to become smaller（As shown in figure 3,2 Fig. 3 of comparison diagram）, the increasing of arm support axial force, cantilever lifting
Security reduces；
4. pulling plate dumpling is selected after auxiliary is required for individually welding, processing, production cost with waist rope dumpling point different position, each dumpling point
It is high；
Tilting moment caused by 5. the weight of boom system itself is bigger is bigger, the amount of deflection of caused arm support during cantilever lifting
Bigger, caused waist rope power is also bigger, and complete machine cantilever lifting difficulty is bigger, and cantilever lifting security is lower.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, can reduce arm support weight, improve arm
Frame stressing conditions improve the plate drawing system that principal arm opens arm ability and security.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of plate drawing system for being used to fix auxiliary operating mode, including being drawn before pulling plate, auxiliary after principal arm pulling plate, waist rope, auxiliary
Plate and auxiliary stent, described principal arm pulling plate one end are connected with the junction of principal arm and auxiliary, pulling plate both ends point before the auxiliary
It not being connected with the auxiliary stent and auxiliary, the waist rope both ends are connected respectively with the principal arm and the principal arm pulling plate,
Pulling plate one end and the auxiliary stent free end, the other end are connected with the principal arm pulling plate after the auxiliary, the auxiliary post-tensioning
The plate tie point of tie point with the waist rope on the principal arm pulling plate on the principal arm pulling plate overlaps.
The waist rope is arranged on the principal arm deflection of arm support maximum.
The waist rope is hinged with the principal arm pulling plate, and the waist rope is total to hinge with pulling plate after the auxiliary and is drawn with the principal arm
Plate is hinged.
Pulling plate includes 2 groups after the waist rope, the principal arm pulling plate and the auxiliary, is symmetrically distributed in the two of the principal arm
On the mainmast of side.
Connector after 2 auxiliarys between pulling plate and the auxiliary stent by isosceles triangle connects.
Pulling plate uses steel plate after the principal arm pulling plate and the auxiliary, and the waist rope uses steel cable.
The advantageous effect that the utility model is reached：
1. compared with prior art, angle increases between pulling plate and auxiliary stent after auxiliary of the invention, auxiliary stent
Axial force accordingly reduces, and contributes to the light-weight design of auxiliary stent, and auxiliary weight support frame mitigates, and cost reduces, cantilever lifting safety
Property increase, elevating capacity gets a promotion；
2. pulling plate is articulated on principal arm pulling plate after auxiliary, compared with prior art, pair can be reduced in principal arm system
Pulling plate dumpling point after arm, it is possible to reduce corresponding manufacturing procedure reduces production cost；There is no in prior art simultaneously（Such as
A-quadrant in Fig. 2）The phenomenon that stress concentration, boom system structure is correspondingly simple, and can reduce the weight of principal arm arm support, cantilever lifting
Security increases, and elevating capacity gets a promotion；
3. pulling plate is articulated on principal arm pulling plate after auxiliary, compared with principal arm pulling plate tool, there are one be lifted up auxiliary pulling plate
Component,（Such as Fig. 5, shown in Fig. 6, Fs1/Fs2 is principal arm pulling plate power；Fh is pulling plate power after auxiliary, and Fh1/Fh2 is pulling plate after auxiliary
The component of power in all directions；Fy is waist rope power）Can to avoid in prior art since the effect of waist rope makes principal arm pulling plate
The phenomenon that angle becomes smaller between principal arm, and can increase angle between principal arm pulling plate and principal arm, arm support axial force is reduced, is risen
Arm security increases；
4. angle reduces between pulling plate and auxiliary stent after auxiliary, pulling plate stress phase after auxiliary during pulling plate stress before equal auxiliary
Answer smaller,（Such as Fig. 7, shown in Fig. 8, Fb is auxiliary stent axial force；Fh is pulling plate power after auxiliary, and Fh3/Fs4 is pulling plate after auxiliary
The component of power in all directions；Fq is pulling plate power before auxiliary, the component of pulling plate power in all directions before Fq1/ Fq2 auxiliarys）It helps
The light-weight design of pulling plate, reduces cost after auxiliary；
5. the weight of boom system and pulling plate itself is significantly reduced, generated tilting moment reduces, cantilever lifting
When caused arm support amount of deflection also reduce, complete machine cantilever lifting difficulty reduce, cantilever lifting security increase.
