Description
Technical field
The utility model relates to a kind of equilibrium arm pull bar auxiliary installation device, specifically a kind of balance arm of tower-type crane pull bar auxiliary installation device.
Background technology
The installation of current cab over type crane balance arm brace group, the mode of usual employing pull bar docking connects, (length is at least by pull bar set of segmentation, short two sections), during installation, long draw is arranged on equilibrium arm, short rod is installed on tower top, the docking of two pull bars is realized while equilibrium arm and tower top docking, during docking, short rod position is fixed, long draw position can lead to adjustment equilibrium arm and hand fit's adjustment, and during pull bar docking, need the positional precision of guarantee two pull bar, the normal docking of two pull bars could be realized easily, but fixing and tying up of pull bar is wasted time and energy, convenience is lower, there is potential safety hazard, for ensureing that pull bar normally docks, need the position of weight-lifting equipment and artificial adjustment long draw simultaneously, pull bar docking difficulty, safety is low.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of balance arm of tower-type crane pull bar auxiliary installation device, the installation site of fixed length pull bar, improves the precision of pull bar docking, improves the convenience and safety of installing.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of balance arm of tower-type crane pull bar auxiliary installation device, comprise equilibrium arm, long draw, auxiliary device, tower top and short rod, one end of long draw is connected with equilibrium arm by bearing pin I, the other end of long draw is connected with one end of short rod by pin, the other end of short rod is connected with tower top by pin shaft II, auxiliary device one end is fixed on equilibrium arm base, the auxiliary device other end is fixed on long draw, and equilibrium arm is connected with tower top by hinge.
Described auxiliary device is made up of supporting plate, pillar and bearing pin, and supporting plate is fixed on pillar one end, and abutment surface has two through holes, and bearing pin is fixedly mounted on abutment surface by through hole.
Base on described bearing pin and equilibrium arm is connected and fixed.
The shape of described supporting plate is " U " type, and long draw is placed in supporting plate " U " type groove, the dead in line of the symmetric line of supporting plate and long draw and short rod.
The beneficial effects of the utility model are: this device mounting structure is simple, can position that is safer and fixed length pull bar easily, the merging precision of two pull bars can be improved, improve and convenience and safety are installed, save human cost, improve the fixing convenience of long draw and safety, the docking location of fixed length pull bar, ensure merging precision, improve and convenience and safety are installed.
