Embodiment Construction

[0032] Embodiment 1 of the side rail type single girder bridge crane of the present invention: as Figure 1-4 As shown in 7-16, the side rail single-girder bridge crane includes a main beam 2 extending in the front-to-back direction, and a trolley 4 assembled on the main beam 2 for guiding movement. The front and rear ends of main beam 2 are provided with running end beams 1, and running end beams 1 run on corresponding cart tracks 11 arranged in the factory building, and running end beams are driven by left and right running motors 12. An end beam electrical box 13 is arranged on the running end beam. The main girder 2 is a box-shaped structure, including a lower cover 25, a first web 27, a second web 24 and an upper cover 26 arranged on the lower cover 25, the first web 27, the second web 24 They are arranged in parallel and located between the upper cover plate 26 and the lower cover plate 25 . Internal ribs are provided inside the main beam 2 . The lower cover plate 25 ...

Abstract

The invention discloses a side rail type single-girder overhead crane. The crane comprises a girder extending in the front-back direction, and a trolley movably assembled on the girder in a guide mode. The trolley comprises an operating mechanism. The girder comprises a lower cover plate. At least one of the left side and the right side of the girder is provided with a bearing rail extending in the front-back direction. The operating mechanism comprises a guide limiting mechanism. A limiting structure which is matched with the guide limiting mechanism in a guide mode and prevents the trolley from being disengaged from the girder in the running process is arranged on the girder. The operating mechanism is located above the lower cover plate of the girder. The trolley is arranged on the two sides or one side, in the length direction, of the girder of the crane, the operating mechanism of the trolley is located above the lower cover plate of the girder, compared with the structural form that in the prior art, the trolley is hung below the girder, the rising height of a hoisting hook of the trolley is not limited by the lower cover plate any more, and the hoisting height of the crane can be obviously increased.

Description

technical field [0001] The invention relates to a side rail type single girder bridge crane. Background technique [0002] Bridge cranes are widely used in production workshops, warehouses, stockyards and other places. For occasions with small lifting capacity, electric hoist single-girder bridge cranes are often used. The structure of the single-girder bridge crane mostly adopts the traditional structural form, the one with a slightly smaller lifting capacity adopts the single-trolley operation structure, and the one with a slightly larger lifting capacity adopts the double-trolley operation structure. The main girder adopts the type of clad I-beam, and the production process of the main girder structure is complicated. For this problem, Chinese patent CN 101973485A (application publication date is 2011.02.16) discloses a new electric hoist single-girder bridge crane. Set between the upper cover and the lower cover, it is a box structure that connects the upper cover and ...
