Bolt is fixed in the rear arm joint, and the U-type groove is located at the top of the hydraulic jacking device；The pull bar is close to preceding arm joint
One end is provided with pull bar pin shaft hole, bearing pin sequentially through the pull bar pin shaft hole and top boom pin shaft hole by the pull bar with it is described on
Chord member is fixed, and the other end of the pull bar is fixed by pin joint with the rear arm joint；And during normal mounting, the pull bar is placed
In in the U-type groove.
During installation, first pull bar is positioned in U-type groove, by adjusting hydraulic jacking device, to adjust pull bar around pin joint
Rotate, and then adjust the relative position of pull bar pin shaft hole and top boom pin shaft hole, until pull bar pin shaft hole and top boom pin shaft hole
Align；After pull bar pin shaft hole and top boom pin shaft hole are aligned, in the presence of hydraulic jacking device, supported by U-type groove
Firmly pull bar, bearing pin is sequentially fixed pull bar with top boom with top boom pin shaft hole through pull bar pin shaft hole.
Compared with prior art, the utility model has the advantages that：
1st, in installation process, will balance arm brace be positioned in U-type groove, can be prevented effectively from pull bar swing, prevent pull bar with
Miscellaneous part collision causes to damage, and extends the service life of derrick crane and pull bar；
2nd,, can be with the height of adjusting yoke pin shaft hole, greatly by the effect of lifting of hydraulic jacking device in installation process
Improve the speed that pull bar pin shaft hole and top boom pin shaft hole are aligned, improve the installation effectiveness of bearing pin；
3rd, this patent is without the use of external equipment (such as truck crane) raising rod, reduces mounting cost；It is not required to artificial support
Lift pull bar, it is to avoid the generation of personal security accident；
4th, using ripe hydraulic technique, safety simple to operate, reliability is high, and maintenance is convenient.
