Abstract
The invention discloses a novel luffing rib ropewalking crawler crane. An integrated guide pulley device is arranged on a luffing rib rear support, and a luffing wire rope is output from a luffing hoist, reaches the integrated guide pulley device on the luffing rib rear support to change the direction of the rope, rises in the luffing rib rear support, reaches to a pulley group at the head of the luffing rib rear support, and then is sequentially wound on a luffing rib front support and the pulley group at the head of the luffing rib rear support; and a lifting wire rope output by a lifting hoist sequentially passes through the integrated guide pulley device and a front lifting wire rope guide pulley device arranged on the luffing rib front support, and finally reaches a luffing rib head guide pulley. The versatility of arm knots of a principal arm can be enhanced without the luffing rib luffing wire rope guide pulley device, so the processing and dismounting complexity is reduced, and the weight of the head of the principle arm is reduced, thereby the overturning moment of the whole crane is reduced, and the arm is easy to lift.
Description
Technical field
The present invention relates to a kind of gear controller, the walk on the rope crawler type of mode of more particularly, to a kind of new variable-amplitude auxiliary arm rises
Heavy-duty machine.
Background technology
With the quickening of Urbanization in China, the fast development of economy, the scale of state fundamental construction is increasing, needs
The weight of article to be lifted and lifting altitude are increasing, and crawler crane increasingly shows its superiority, and crawler type rises
Heavy-duty machine has obtained swift and violent development.Crawler crane, in order to improve its lifting altitude and work range, is commonly designed installation and becomes
Width auxiliary.
As shown in figure 1, principal arm system has a special elevator joint near arm support heel, elevator joint is provided with variable-amplitude auxiliary arm
Luffing elevator (sequence 02), variable-amplitude auxiliary arm luffing elevator (sequence 02) is upper to be wound around variable-amplitude auxiliary arm variable-amplitude steel wire rope (sequence 04)；Principal arm system
There is a special transition arm joint at arm head, this transition segment is provided with variable-amplitude steel wire rope guide pulley device (sequence 03)；Become
Width auxiliary variable-amplitude steel wire rope (sequence 04) is after variable-amplitude auxiliary arm luffing elevator (sequence 02) output through variable-amplitude steel wire rope leading block dress
Put (sequence 03) and reach variable-amplitude auxiliary arm support (sequence 07-2) head assembly pulley afterwards, be then wrapped in variable-amplitude auxiliary arm support (sequence 07- successively
1st, sequence 07-2) on head assembly pulley；Pass through variable-amplitude auxiliary arm luffing elevator (sequence 02) during work to withdraw or release variable-amplitude auxiliary arm luffing
Steel wire rope (sequence 04) changes the purpose of amplitude to reach variable-amplitude auxiliary arm (sequence 08).The raising steel wire exporting from raising elevator (sequence 01)
Rope (sequence 05), sequentially passes through the hoist rope guide pulley device (sequence 06) on variable-amplitude auxiliary arm support (sequence 07), finally reaches
Variable-amplitude auxiliary arm arm head leading block (sequence 010), thus realize lifting.Wherein variable-amplitude auxiliary arm support hoist rope leading block dress
Put concrete pulley arrangements as shown in Figure 9.
As shown in fig. 7, during principal arm operating mode, the hoist rope (sequence 05) that exports from raising elevator (sequence 01), it is directly over
The hoist rope guide pulley device (sequence 012) of principal arm head, thus realize lifting；As seen from Figure 8, because elevator has
There is certain width, hoist rope can move back and forth along the direction of arrow shown in Fig. 8, when hoist rope is from volume on elevator
When raising side and changing to opposite side, hoist rope is passed by certain angle.
Cantilever lifting is that boom system is lifted to the process of required working condition position by crane.Outstanding for crawler crane
It is large tonnage crawler crane, and cantilever lifting operating mode is the most dangerous, worst operating mode, and the success or not of cantilever lifting is directly connected to
Operation can be carried out, the danger such as even structural member damages, whole machine is tumbled.It is illustrated in figure 5 crawler crane principal arm operating mode
Cantilever lifting schematic diagram, as seen from Figure 5, during cantilever lifting, arm support can produce a downward amount of deflection, and arm support weight is especially near arm
Head at the heavier amount of deflection of weight bigger, with the increase of amount of deflection, the difficulty of cantilever lifting also increases, therefore, the difficulty of arm support to be controlled and
The amount of deflection of arm support during cantilever lifting.
Above-mentioned crawler crane has the disadvantage in that
1. need special variable-amplitude steel wire rope guide pulley device, as shown in Fig. 2 and being used for being fixedly connected this luffing steel
Cord guide pulley device: special principal arm transition segment, reduces the versatility between principal arm arm joint, the overall processing increasing arm support is complicated
Property, increase cost；
2. what principal arm transition segment can only be fixed is assemblied in the position near arm head, increases complexity when installing；
3. variable-amplitude steel wire rope guide pulley device is special in principal arm transition segment installation site a region needs as shown in Figure 4
Strengthen to adapt to pulling force produced by variable-amplitude steel wire rope, lead to this transition segment weight to increase, and the installation site of this transition segment must
Must be near arm head so that whole arm support weight at arm head increase, the more big produced tilting moment of weight of arm support itself
And amount of deflection during cantilever lifting is bigger, the cantilever lifting difficulty of whole machine is bigger；
4. crawler crane, due to being limited by transportation clearance and hauled weight, generally requires before and after operation to be torn open
Dress, variable-amplitude auxiliary arm variable-amplitude steel wire rope is also required to winding repeatedly, is illustrated in figure 6 variable-amplitude steel wire rope fall line when variable-amplitude auxiliary arm is installed
Schematic diagram, it can be seen that variable-amplitude steel wire rope variable-amplitude auxiliary arm frame upper walk on the rope, due to variable-amplitude auxiliary arm need complete
Various functions, this frame upper has a considerable amount of adnexaes, such as the attached smallclothes such as arm-tie bracket, in variable-amplitude steel wire rope wire rope handling
Inevitably interfere with these adnexaes, cause the damage of structural member or the abrasion of steel wire rope etc.；
5., under principal arm operating mode, the hoist rope guiding that hoist rope reaches principal arm head from after lifting mechanism output is slided
Wheel apparatus, when in hoist rope moving process on lifting mechanism can and principal arm transition segment on variable-amplitude steel wire rope leading block
Device interference, leads to structural member and steel wire rope to damage, therefore needs to fill variable-amplitude steel wire rope leading block under principal arm operating mode
Put dismounting, increase the complexity of dismounting；
6., when transporting, principal arm transition segment is due to variable-amplitude auxiliary arm variable-amplitude steel wire rope guide pulley device superelevation, as shown in figure 3, h
Height, need to remove this guide pulley device and individually transport, increase cost of transportation, reduce labor efficiency simultaneously.
