Description
【Technical field】
The present invention relates to a kind of fixed cranes.
【Background technology】
The common fixed crane in existing market has the following disadvantages:
Firstth, there is back-roll phenomenon in steel wire rope, and rope service-life is shorter;
Secondth, grab bucket operation when can reverse-winding, grab bucket operation lifting velocity is fast, and impact is big, and there are zero loads and heavy burden
The alternate situation of lotus is rewound due to existing, and steel wire rope easily beats strand, is not suitable with grab bucket operation;
Third, A-frame front leg strut wear axis pin with turret assembly together with arm support and be hinged, rear support leg pulling plate and turntable
It wears axis pin to be hinged, this articulated manner can generate shaking there are gap, and rigidity is poor;
4th, turret assembly arrangement space, which exists, intersects, since A-frame front leg strut is arranged in turret assembly forepart, herringbone
Frame rear support leg is arranged in again in the middle part of turret assembly, and lifting amplitude-change mechanism needs to carry out interference checking.Single lifting mechanism is used for suspension hook,
For double lifting mechanisms for grabbing bucket, the structure of A-frame limits freely arranging for lifting mechanism, is required for carrying out in detail every time
Interference checking, it is very troublesome;
5th, back-roll is formed at load power taking pulley:Load power taking pulley is arranged on A-frame foreleg centre position, steel
Cord leads to A-frame head leading block, then lead to arm support head, steel wire rope exists after reel comes out by load power taking pulley
Back-roll can be formed at load power taking pulley;
6th, single-point compensates, and during luffing, the horizontal difference of height of suspension hook and arm support stress balance are general, during design, such as wants to obtain
Preferable horizontality is obtained, then needs suitably to sacrifice arm support stress equalization.
The present invention is namely based on what such case was made.
