Including counter-jib arm joint and counter-jib periproct, the wherein lower boom of counter-jib arm joint is connected with counter-jib periproct, counter-jib
Be connected by pull bar between the top boom of arm joint and counter-jib periproct, pull bar when the top boom with counter-jib arm joint is connected,
Need first to raise the end of pull bar by hanger by external equipment (such as truck crane), then slowly putting down makes the bearing pin of pull bar
Hole aligns with the pin shaft hole of top boom, could install connection bearing pin, pull bar is connected with the top boom of counter-jib arm joint.
General to align pin shaft hole using two ways when installing connection bearing pin, one is using external equipment (such as truck crane)
Hanger (referring to the mark 8 in Fig. 1) on pulling pull bar lifts tie rod end pin shaft hole and top boom pin shaft hole is aligned, and two are
Pull bar is lifted using the artificial mode of lifting.During using first method, the cost of use of external equipment (such as truck crane) is higher, meeting
Increase cost, during using second method, personnel are easily tired, can cause security incident.And, both the above method all can not
Ensure the stabilization in pull bar installation process, cause pull bar easily to touch counter-jib other structures and cause to damage, simultaneously for large-scale
Derrick crane for, pull bar weight is bigger, and aligning for pin shaft hole is also more difficult.
The content of the invention
It is an object of the invention to provide one kind can solve to balance in the prior art installation difficulty when arm brace row is installed it is big,
High cost, the balance arm brace of bearing pin installation difficulty install auxiliary body.
To achieve the above object, the present invention provides a kind of balance arm brace and installs auxiliary body, for aiding in tower lifting
The installation of machine counter-jib, the counter-jib includes preceding arm joint, rear arm joint and pull bar, lower boom and the rear arm joint of the preceding arm joint
Front end is connected, and the top boom of the preceding arm joint is connected so as to realize and rear arm joint through top boom pin shaft hole by bearing pin with pull bar
The connection of rear end；The auxiliary body includes hydraulic jacking device and U-type groove, and the lower end of the hydraulic jacking device is solid by bolt
Due in the rear arm joint, the U-type groove is located at the top of the hydraulic jacking device；The pull bar is near one end of preceding arm joint
Pull bar pin shaft hole is provided with, bearing pin sequentially passes through the pull bar pin shaft hole and top boom pin shaft hole by the pull bar and the top boom
Fixed, 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 positioned over institute
State in U-type groove.
During installation, first pull bar is positioned in U-type groove, pull bar is adjusted around pin joint by adjusting hydraulic jacking device
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 invention 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, in installation process, by the effect of lifting of hydraulic jacking device, can be with the height of adjusting yoke pin shaft hole, greatly
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.
