Abstract

The invention discloses a twin-tower type crane which comprises a primary tower body, a crane boom, an auxiliary tower body, a rubber-tyred chassis and a supporting frame, wherein the primary tower body is fixed on the supporting frame; the auxiliary tower body is fixed on the rubber-tyred chassis; a primary tower body standard segment, a primary tower body rotating mechanism and a lifting mechanism are arranged on the primary tower body; the crane boom is arranged at the upper part of the primary tower body; a winch drum, a pulley, a variable-amplitude trolley and an auxiliary tower body rotating mechanism are arranged on the crane boom; a lifting hook is arranged on the variable-amplitude trolley; an auxiliary tower body standard segment is arranged on the auxiliary tower body; and the auxiliary tower body rotating mechanism is connected with the auxiliary tower body. When the twin-tower type crane rotates, the primary tower body is fixed on the supporting frame without movement and provides the rotating power, so that the crane boom and the auxiliary tower body do not infinitely rotate and only can rotate around the primary tower body within a larger circular arc; and the auxiliary tower body and a part of lifting weight are supported by the rubber-tyred chassis. The twin-tower type crane is suitable for large lifting capacity and large lifting height and has high strength and rigidity.

Description

A kind of double-tower type hoisting crane
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; 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; Crane arm and secondary tower body are rotated round the king-tower body; Rotation is not unlimited rotation; Can only in a bigger circular arc, rotate back and forth, the weight of secondary tower body and part lift heavy is being supported on the rubber-tyred chassis.
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; King-tower body standard knot is installed on one's body the king-tower; This wants earlier secondary tower body swing type mechanism and secondary tower status to be 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; Allow 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.
Description of drawings
Fig. 1 is a double-tower type crane structure scheme drawing;
Fig. 2 is the structural representation of the independent self-raising tower crane of king-tower body and crane arm formation.
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 as shown in Figure 1, 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; Crane arm 2 and secondary tower body 3 are rotated round king-tower body 1; 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.
