The pulley assembly (19,20) that is loaded on upright top, osmanthus, crane arm top is respectively arranged in the above-mentioned luffing mechanism, be loaded on the leading sheave in the pivoting support, the pulley assembly (19) that is connected in winch, steel rope one end goes up and the other end is walked around behind pulley assembly (20,19), the leading sheave and be connected with winch (referring to Fig. 1～Fig. 4).
The pulley that is loaded on column upper end, crane arm lifting end is respectively arranged in the above-mentioned lifting mechanism, be loaded on the leading sheave in the Slewing Support Mechanism, winch, steel rope one end are connected on the crane arm and the other end is walked around and is connected behind the hook assembly that contains suspension hook and movable pulley, the pulley on the crane arm, the pulley on the column, the leading sheave on the winch (referring to Fig. 1～Fig. 4).
The hawser swivel base that is loaded on column top is arranged in the above-mentioned tensioning stabilizing mechanism, contain the pre-buried bearing of hawser that at least three one ends can place flooring, hawser one end is connected on the hawser swivel base and the other end is connected (referring to Fig. 1) with the pre-buried bearing of hawser, to guarantee the assembled machine balance under the lifting work situation, the disposable hexagonal angle degree gyroscopic movement of doing of jib.
The pre-buried bearing of above-mentioned hawser is six, can make the gyroscopic movement of 360 ° of angles.
The tensioning nut (referring to Fig. 1) that adjustable degree of tightness is arranged on the pre-buried bearing of above-mentioned hawser.
When using the utility model, Slewing Support Mechanism is fixed on the flooring, column, crane arm are installed on the Slewing Support Mechanism, the pre-buried bearing of hawser is contained in the flooring and with lifting mechanism, luffing mechanism installs.Starting lifting mechanism, luffing mechanism just can be worked.
The utlity model has following advantage:
1, owing to selected Slewing Support Mechanism for use, make revolution strength less, and structure is very compact, manually revolution becomes possibility, so can adopt manual revolution or motor-driven revolution mode, convenient operation and control;
2, owing to can in lifting, luffing, swing type mechanism, erection weight limit and the angle limits safety device, improved the safety of high-rise operation;
3, owing to adopted the tensioning stabilizing mechanism, kept complete machine work balance, avoided the normally used big weight balancing of hoisting crane heavy, made things convenient for transporting of roof;
4, all mechanisms are all assembled by monomer, assembly that weight is little, make its machinery dismounting as the last work of roof become easy thing, convenient disassembly;
5, reusable, maintenance cost is low, and past-sale service is secure, has greatly reduced the dismounting cost of inner climbing type hoisting crane, and it is big to promote the use of scope.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is that A among Fig. 1 is to view.
Fig. 3 is that B among Fig. 1 is to view.
