Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
The self-propelled crane that the present invention proposes, as depicted in figs. 1 and 2, comprising: crane arm 1, pull bar 2, Shears 3, lifting mechanism 4, luffing mechanism 5, swing type mechanism 6, turntable 7, base 8, suspender 9;
Be provided with walking and fixed mechanism bottom base 8, comprise wheel 802 and telescoping support pin 803.This hoisting crane can move easily, is applicable to material to hang toward fixed venue from barge or compartment.Telescoping support pin 803 can, after hoisting crane stops, stably stop to keep balance on the ground.
Base 8 top is provided with a revolving support 801, and the revolving support 801 that turntable 7 is arranged on base 8 can do gyroscopic movement; Shears 3 is arranged on turntable 7, and the top of Shears 3 and one end of pull bar 2 are rotationally connected; Pull bar 2 is provided with stay cord, and is connected with crane arm 1 top by stay cord; The top of crane arm 1 hangs suspender 9; End and turntable 7 front end of crane arm 1 are rotationally connected; Turntable 7 is installed lifting mechanism 4, luffing mechanism 5 and swing type mechanism 6; Lifting mechanism 4 connects the suspender 9 on crane arm by lifting rope; Stay cord on luffing mechanism 5 cylinder lever connecting rod 2; Swing type mechanism 6 is connected with the revolving support 8 on base 8.
Crane arm 1 is welded by shaped steel, safe and reliable.The material of pull bar and Shears also adopts shaped steel.Lifting mechanism 4 is provided with major-minor Liang Tao mechanism, is the propulsion source of lifting cargo.Luffing mechanism 5 can make crane arm 1 do luffing motion flexibly, makes lifting wider.Swing type mechanism 6 can make hoisting crane top do level 360 ° revolution arbitrarily, makes lifting wider.Turntable 7 is the platforms installing lifting mechanism 4, luffing mechanism 5, swing type mechanism 6.
