B) under tower auxiliary operating mode: the implementation procedure of double hook compound lifting upset lifting object, as shown in Fig. 6 (a), Fig. 6 (b) He Fig. 6 (c), main hook 3 and auxiliary hook 4 lift object simultaneously, and object overturns, release auxiliary hook 4.
The utility model can increase by the combination of the length of the length of different principal arm 1 and different auxiliary 2 the lifting scope and hoisting height that cover hoisting crane.
Prior art is that main hook and auxiliary hook are arranged separately separately, can only independently use, the crawler crane of the energy double hook lifting that the utility model provides, main hook 3 and auxiliary hook 4 are put together use simultaneously, its contrast arm end single-sheaved block structure, under fixing auxiliary and tower auxiliary operating mode, connection and the composition form of jib have a very large change, fixing auxiliary operating mode and tower auxiliary operating mode, its boom system forms complicated, hoisting capacity is large, stressed complexity, calculate the lifting performance of jib structure intensity, to the linear calculating of in jib integral structure and truss structure point of limb pipe, NONLINEAR CALCULATION and corresponding side travel etc. carry out computational analysis, in original single hook lifting operation, calculated amount is large and complicated, the particularly calculating of structural nonlinear.
The construction design method of the crawler crane of the energy double hook lifting that the utility model provides needs to consider following factor:
1), when principal arm 1 main hook 3 lifting operation calculates, need consider that whole Auxiliary arm system acts on the power on principal arm 1 and the impact on principal arm 1;
2), when auxiliary 2 auxiliary hook 4 lifting operation calculates, the stressed of principal arm 1 main hook 3 pairs of boom systems need be considered;
3) double hook simultaneously lifting operation time, consider that auxiliary 2 auxiliary hook 4 and principal arm 1 main hook 3 act on the stressed of boom system simultaneously simultaneously.
Above three kinds calculate, and particularly under the superposition operation of two power, the power transmission of whole boom system will change a lot with effect, particularly non-linear and non-linear superpose and interactional calculating.
4) also need to consider that principal arm 1 calculates from the composite condition of auxiliary 2 under different jib length to the calculating of said arm frame system.
The hoisting capacity determined by complete machine stability, because principal arm 1 and auxiliary 2 length are not fixing, jib length can freely increase or reduce, and the combination between various jib length all needs to calculate.In existing single hook lifting operation, try to achieve under various jib composite condition whole boom system stressed after, corresponding performance table can be obtained according to principle of moment balance.
The construction design method of the crawler crane of the energy double hook lifting that the utility model provides, the calculating of performance table comprises:
1) calculating of principal arm 1 main hook 3 lifting operation, need by principal arm system and Auxiliary arm system separate computations, under often kind of principal arm operating mode, after corresponding Auxiliary arm system stressed all will calculate, remake for principal arm 1, after superposing with the lifting amount of principal arm 1, then obtain corresponding performance table according to principle of moment balance.
2) calculating of auxiliary 2 auxiliary hook 4 lifting operation, in like manner also needs principal arm system to separate with Auxiliary arm system, after superimposed for the moment of the moment of the load on main hook 3 and auxiliary 2 auxiliary hook 4, obtains performance table according to principle of moment balance.
3) during double hook operation simultaneously, when this operating mode needs to consider that main hook 3 and auxiliary hook 4 lift at the same time especially, the impact of stressed alternately change on whole vehicle stability, principal arm system and Auxiliary arm system calculate rear superposition respectively, obtain performance table according to principle of moment balance.
Under auxiliary double hook working condition, one is that combination variety between different jib is more, two is the main hook 3 on principal arm 1 and the auxiliary hook 4 on auxiliary 2, the kind of suspension hook used can change, the change of kind and cause suspension hook weight to change, and then cause changing to the size of the power acting on boom system, thus need further, to under various jib combination, carry out the calculating of the combination of various suspension hook.
The construction design method of the crawler crane of the energy double hook lifting that the utility model provides, the calculating of above-mentioned often kind of performance table all specifically needs to calculate following parameter:
1. the calculating of jib load-carrying capacity:
A, jib Linear Stability calculate rated load;
B, jib nonlinear stability calculate rated load;
C, jib arm head side travel calculate rated load;
D, jib divide limb pipe stable calculation rated load;
Calculating above four kinds of rated load values, by comparing the size of four numerical value, getting the rated load that wherein minimum value calculates as jib load-carrying capacity.
2. the calculating of complete machine rated load:
The rated load that E, acquisition jib load-carrying capacity calculate;
F, calculate the rated load determined by pivoting support ability;
G, calculate the rated load determined by complete machine stability;
H, calculate by arm-tie, mast determine rated load;
I, calculate by promote hoisting mechanism determine rated load;
J, calculate by main transformer width hoisting mechanism determine rated load.
Draw respectively above six kinds calculate rated load values, by comparing the size of six numerical value, get wherein minimum value as complete machine rated load.
Wherein, in above-mentioned calculating, calculation method for stability is: moment algebraic sum is more than or equal to zero, that is:
∑M＝M
Q-M
B≥0
Wherein: M is resultant moment; M
qfor complete machine hoisting moment, M
bfor lift heavy hoisting moment.
The crawler crane of the energy double hook lifting that the utility model provides is under auxiliary operating mode, the arm end of principal arm 1 and the arm end of auxiliary 2 hang suspension hook simultaneously, have expanded out the lifting operating mode that three kinds of crawler crane are new: the main hook operating mode of band auxiliary, the auxiliary operating mode of band main hook and major-minor hook compound lifting operating mode; Three kinds of operating modes have engineer applied widely, improve the operating efficiency of loop wheel machine, reduce hoisting cost, meet market development needs.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
