The crane jib is arranged on the upper portion of the main tower body. The crane jib is equipped with a hoisting drum, a pulley, a jib lubbing trolley and a swing mechanism of the vice tower body. The jib lubbing trolley is provided with a hook. The vice tower body is provided with a standard joint of the vice tower body. The swing mechanism of the vice tower body is connected with the vice tower body. Application: during the rotary motion of the twin tower crane, the main tower body is fixed on the support frame and doesn't move; the main tower body provides rotary power such that the crane jib and the vice tower body rotate around the main tower body; the rotation is not unlimited but is an oscillating rotary motion in a relatively large circular arc; the rubber-tyred chassis supports the weight of the vice tower body and parts of lifting weight. The utility model is suitable for large lifting weight and large lifting height, and has very high strength and rigidity.
Description
Technical field
The present invention relates to a kind of double-tower type hoisting crane, belong to lifting transportation technology field.
Background technology
As everyone knows; The structure and the building operation demand of tower machine product are closely related, and China's architectural development situation is just trending towards high-rise superelevation layer development at present, and the application of large-scale prefabricated member is increasingly extensive; Though incity, city skyscraper can solve the lifting problem through attached tower crane; But for harbour one band, this big hoisting capacity, lifting altitude and activity space just are difficult to meet the demands.
Summary of the invention
To above-mentioned deficiency, the invention provides a kind of double-tower type hoisting crane, its together support through king-tower body and secondary tower body solves lifting altitude, plays the problem of heavy lift and working space.
The present invention realizes through following technical scheme:
A kind of double-tower type hoisting crane comprises king-tower body, crane arm, secondary tower body, rubber-tyred chassis and bracing frame, and wherein, the king-tower body is fixed on the bracing frame, and the secondary tower body is fixed on the rubber-tyred chassis; King-tower is provided with king-tower body standard knot, king-tower body swing type mechanism and lifting mechanism on one's body, and crane arm is located at the king-tower body, and crane arm is provided with winding drum, pulley, amplitude variation trolley and secondary tower body swing type mechanism, and amplitude variation trolley is provided with suspension hook; Secondary tower is provided with secondary tower body standard knot on one's body, and secondary tower body swing type mechanism is connected with the secondary tower body.
During use, said king-tower body is fixed, and the secondary tower body can be around the rotation of king-tower body.
Use: the double-tower type hoisting crane is when gyroscopic movement; The king-tower body is fixed on the bracing frame motionless; The king-tower body provides rotary motive power, makes crane arm and secondary tower body round the rotation of king-tower body, and rotation is not unlimited rotation; Can only in a bigger circular arc, rotate back and forth, the rubber-tyred chassis supports the weight of secondary tower body and part lift heavy.
The double-tower type hoisting crane is hoisting when motion, the stop motion of secondary tower body, and the suspension hook weight of slinging, and under the combined action of winding drum, pulley and amplitude variation trolley, accomplish the mobile of lift heavy.
The lifting of double-tower type hoisting crane oneself height; Rising certainly of king-tower body can be under the effect of lifting mechanism, and king-tower body standard knot is installed on one's body the king-tower, and this wants earlier secondary tower body swing type mechanism and secondary tower status are left; The rising of secondary tower body need wait the king-tower body after rising end; Suspension hook hangs a joint secondary tower body standard knot and is installed on one's body the secondary tower, and then secondary tower body and secondary tower body swing type mechanism are connected, and accomplishes the lifting of oneself height.
In addition, said king-tower body and crane arm can constitute a tower crane independently, and when hoisting capacity was smaller, king-tower body and crane arm can constitute a relatively independent self-raising tower crane.
The present invention utilizes the king-tower body that rotary power is provided; Secondary tower cooperates crane arm around the rotation of king-tower body for the rubber-tyred chassis; Weight turns round the motion that is implemented in the working space by means of dolly, lifting mechanism and crane arm between two bodies of the tower, thereby realizes hoisting of ultra-large type weight.
The present invention utilizes the together support of king-tower body and secondary tower body; Let crane arm form a kind of simple beam structure; Increase the ability of crane arm and body of the tower bearing load; Can be fit to big hoisting capacity and big lifting altitude, have very high strength and stiffness and resistance to overturning, have advantages such as structure is ingenious, result of use is good.

Wherein, 1, king-tower body; 2, crane arm; 3, secondary tower body; 4, king-tower body standard knot; 5, secondary tower body standard knot; 6, king-tower body swing type mechanism; 7, secondary tower body swing type mechanism; 8, lifting mechanism; 9, rubber-tyred chassis; 10, bracing frame; 11, winding drum; 12, pulley; 13, amplitude variation trolley; 14, suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing invention is further described.
A kind of double-tower type hoisting crane comprises king-tower body 1, crane arm 2, secondary tower body 3, rubber-tyred chassis 9 and bracing frame 10, and is as shown in Figure 1, and wherein, king-tower body 1 is fixed on the bracing frame 10, and secondary tower body 3 is fixed on the rubber-tyred chassis 9; King-tower body 1 is provided with king-tower body standard knot 4, king-tower body swing type mechanism 6 and lifting mechanism 8; Crane arm 2 is located at king-tower body 1 top; Crane arm 2 is provided with winding drum 11, pulley 12, amplitude variation trolley 13 and secondary tower body swing type mechanism 7, and amplitude variation trolley 13 is provided with suspension hook 14; Secondary tower body 3 is provided with secondary tower body standard knot 5, and secondary tower body swing type mechanism 7 is connected with secondary tower body 3.
During use, said king-tower body 1 is fixed, and secondary tower body 3 can be around 1 rotation of king-tower body.
Use: the double-tower type hoisting crane is when gyroscopic movement; King-tower body 1 is fixed on the bracing frame 10 motionless; King-tower body 1 provides rotary motive power, and crane arm 2 and secondary tower body 3 are rotated round king-tower body 1, and rotation is not unlimited rotation; Can only in a bigger circular arc, rotate back and forth, the weight of secondary tower body 3 and part lift heavy is being supported on rubber-tyred chassis 9.
The double-tower type hoisting crane is hoisting when motion, 3 stop motions of secondary tower body, and suspension hook 14 weight of slinging, and under the combined action of winding drum 11, pulley 12 and amplitude variation trolley 13, accomplish the mobile of lift heavy.
The lifting of double-tower type hoisting crane oneself height; Certainly the liter of king-tower body 1 can be installed in king-tower body standard knot 4 on the king-tower body 1 under the effect of lifting mechanism 8, and this wants earlier secondary tower body swing type mechanism 7 is separated with secondary tower body 3; The rising of secondary tower body 3 need wait king-tower body 1 after rising end; Suspension hook 14 hangs a joint secondary tower body standard knot 5 and is installed on the secondary tower body 3, and then secondary tower body 3 and secondary tower body swing type mechanism 7 are connected, and accomplishes the lifting of oneself height.
In addition, double-tower type hoisting crane page or leaf of the present invention can constitute a tower crane independently, and when hoisting capacity was smaller, king-tower body and crane arm can constitute a relatively independent self-raising tower crane, and be as shown in Figure 2.
