Embodiment 1

[0025] Embodiment 1 is a crane in which a set of trolley traction mechanism 5 drags a lifting trolley 1 , and trolley traction mechanism 5 is arranged at one end of bridge frame 2 .

Embodiment 2

[0026] Embodiment 2 is a crane in which two sets of trolley traction mechanisms 5 drag two lifting trolleys 1. The trolley traction mechanisms 5 are located at both ends of the bridge frame 2, and each set of trolley traction mechanisms drags one lifting trolley.

Abstract

The invention discloses a traction type arch-bridge crane of a crane carriage. The traction type arch-bridge crane comprises the crane carriage, a crane span structure, a cart travelling mechanism and electrical control equipment, wherein the crane span structure is a four-beam structure which is arched in middle; a crane carriage travelling rail on the crane span structure is laid along an arched main beam upper cover; a trolley travelling mechanism of the crane carriage is a trolley traction mechanism which is arranged on the end part of the crane span structure; the trolley traction mechanism drives a winding drum set to rotate by virtue of a motor and a speed reducer, so that a steel wire rope wound on the winding drum set is synchronously collected and released to generate traction drive for driving the crane carriage to move. The traction type arch-bridge crane has the beneficial effects that: a mid-span part is high in lifting height, and a space utilization rate of a plant ceiling is increased; driving torque of the trolley traction mechanism is small, so that the crane carriage is safe and stable in operation, and relatively high in positioning precision; civil engineering construction cost can be reduced for a special occasion; and the design is compact, space usage is small and the space utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of cranes, in particular to bridge cranes. Background technique [0002] The bridge frame of the traditional bridge crane is a horizontal four-beam structure, and the lifting trolley runs back and forth on the horizontal bridge frame to lift objects. The shortcomings of traditional bridge cranes are: they cannot meet the special requirements of special workshops and users, such as the occasions where the upper ceiling is arc-shaped, the lifting height of the middle part of the bridge frame is relatively large, and the lifting height of both ends is low. Contents of the invention [0003] The object of the present invention is to provide a kind of bridge crane with arched main girder which is suitable for the occasions where the lifting height of the middle part is relatively large and the lifting height of both ends is relatively low. [0004] The technical solution of the present invention is: a hoisting...
