Abstract
The utility model discloses a novel pulley mounting fixed knot constructs for jib loading boom, include and install at the inboard pulley of four sections arm tail ends through bolt, baffle and round pin axle, the bolt passes through baffle fixed pulley, the pulley overhead has the rough cable of drive pentamera arm, the baffle is disc construction, and open at the middle part has the bolt hole, the baffle periphery highly is greater than inboard thickness, can make the bolt of installation baffle not be higher than the baffle surface, the round pin axle is through reinforcing plate fixed pulley, round pin axle and reinforcing plate agree with the position side and are the straight flange structure. The utility model discloses simple structure, the effect is obvious, is favorable to alleviating pentamera arm barrel abrupt change of cross -section degree, makes it self reach full semi -girder performance maximize, the grinding deforming and breaking of mounting hole on four sections arms has been avoided causing because the round pin axle rotates, and richened the round pin axle installation fixing form of pulley.
Description
Technical field
This utility model relates to a kind of crane arm installation auxiliary device, belongs to engineering machinery field, and fixed structure installed by specifically a kind of Novel crane boom pulley.
Background technology
At present, in the rope formula telescoping mechanism of crane arm, hoisting of five joint arms is realized by rough rope II and pulley, and pulley is fixed on four joint arm cylinders by bearing pin.The installation form of the most conventional rough rope II pulley and four joint arms is to utilize bolt fastening baffle plate and bearing pin to realize the installation of pulley, and bearing pin is with pulley rotation, we term it traditional pulley pin shaft fixed form.Traditional pulley pin shaft fixed form exacerbates the sudden change in five joint arm cylinder cross sections, is unfavorable for the maximizing performance of five joint arms, and then affects the performance of the full semi-girder of crane arm；Bearing pin is with pulley rotation simultaneously, easily causes four joint arm bearing pin installing holes for a long time and deforms because of grinding, affects hoisting of five joint arms.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of Novel crane boom pulley to install fixed structure, can effectively alleviate five joint arm cylinder abrupt change of cross-section degree so that it is self and full semi-girder maximizing performance；Avoid and cause the grinding deformation failure of installing hole on four joint arms owing to bearing pin rotates.
To achieve these goals, the technical solution adopted in the utility model is: fixed structure installed by a kind of Novel crane boom pulley, including being arranged on the pulley inside four joint arm tail ends by bolt, baffle plate and bearing pin, described bolt passes through baffle plate fixed block, and described pulley is equipped with the rough rope driving five joint arms；Described baffle plate is disc-shaped structure, and middle part has bolt hole, and described baffle plate periphery height is more than inner thickness, and the bolt of installation baffle plate can be made to be not higher than baffle plate outer surface；Described bearing pin passes through reinforcing plate fixed block, and it is straight flange structure that described bearing pin and reinforcing plate agree with position side, by the rotation coordinating restriction bearing pin of straight flange structure.
Preferably, described reinforcing plate is high-strength steel sheet, can effectively limit the rotation of bearing pin, improves and uses durability degree.
Preferably, described baffle plate is machined piece, it is ensured that the precision of accessory size, more puts in place with bolt and coordinating of pulley.
The beneficial effects of the utility model are: be conducive to alleviating five joint arm cylinder abrupt change of cross-section degree so that it is self and full semi-girder maximizing performance；Avoid and cause the grinding deformation failure of installing hole on four joint arms owing to bearing pin rotates；And the bearing pin enriching pulley installs fixed form.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, fixed structure installed by a kind of Novel crane boom pulley, including being arranged on the pulley 3 inside four joint arm cylinder 6 tail ends by bolt 8, baffle plate 2 and bearing pin 1, described bolt 8, by baffle plate 2 fixed block 3, described pulley 3 is equipped with the rough rope 4 driving five joint arm cylinders 7；Described baffle plate 2 is disc-shaped structure, and centre has bolt hole, and the peripheral height of described baffle plate 2, more than inner thickness, can make the outer surface of the bolt 8 not higher than baffle plate 2 of installation baffle plate 2；Described bearing pin 1 is by reinforcing plate 5 fixed block 3, and the position side that agrees with of described bearing pin 1 and reinforcing plate 5 is straight flange structure, by the rotation coordinating restriction bearing pin 1 of straight flange structure, thus avoids installing hole and deforms because of abrasion.
Preferably, described reinforcing plate 5 is high-strength steel sheet, can effectively limit the rotation of bearing pin 1, improves and uses durability degree.
Preferably, described baffle plate 2 is machined piece, it is ensured that the precision of accessory size, more puts in place with bolt and coordinating of pulley.
In sum, this utility model simple in construction, effect is obvious, is conducive to alleviating five joint arm cylinder abrupt change of cross-section degree so that it is self and full semi-girder maximizing performance；Avoid and cause the grinding deformation failure of installing hole on four joint arms owing to bearing pin rotates；And the bearing pin enriching pulley installs fixed form.
