Embodiment 1

[0051] refer to Figure 1 to Figure 4 , Embodiment 1 of the present invention provides a quay crane, the quay crane can not only adjust the height of the quay crane, but also can adjust the outreach and back reach of the quay crane. Such as figure 1 As shown, the quay bridge includes a door frame structure 10 , an upper girder structure 20 and a bottom support structure 30 , the door frame structure 10 is set on the bottom support structure 30 , and the upper girder structure 20 is set on the door frame structure 10 . The door frame structure 10 includes a sea side door frame column 11 , a land side door frame column 12 and a first diagonal brace 13 . Specifically, such as figure 2 As shown, the sea side door frame column 11 and the land side door frame column 12 are along the first direction ( figure 1 , figure 2 As shown in X, that is, the direction in which the rear girder 233 extends) is arranged in parallel and equal in length, wherein there are two sea-side door fr...

Embodiment 2

[0066] next reference Figure 5 to Figure 13 Introduce another embodiment 2 of the present invention. The difference between embodiment 2 and embodiment 1 is that the structure of the sea side door frame column is different from that of the land side door frame column, and the quay bridge of this embodiment also includes a second diagonal brace 14 And the connecting beam 15 in the middle.

[0067] Further, in the second embodiment, as Figure 5 to Figure 9 As shown, the sea side door frame column 11 includes a first sea side column 111 and a second sea side column 112, the land side door frame column 12 includes a first land side column 121 and a second land side column 122, and the door frame structure 10 also includes a second Diagonal struts 14 and intermediate connecting beams 15.

[0068] The bottom end of the first sea-side column 111 and the top end of the second sea-side column 112 are hinged at the middle hinge point E on the sea side, and the top end of the first s...

Abstract

The invention discloses a shore crane. The shore crane comprises an upper girder structure, a door frame structure and a bottom supporting structure, wherein the door frame structure comprises sea-side door frame stand columns, land-side door frame stand columns and first diagonal braces, the top ends of the sea-side door frame stand columns and the upper girder structure are hinged at sea-side upper hinged points, and the bottom ends of the sea-side door frame stand columns and the bottom supporting structure are hinged at sea-side lower hinged points; the top ends of the land-side door frame stand columns and the upper girder structure are hinged at land-side upper hinged points, and the bottom ends of the land-side door frame stand columns and the bottom supporting structure are hinged at land-side lower hinged points; the two ends of each first diagonal brace are hinged to the corresponding sea-side door frame stand column and the corresponding land-side door frame stand column respectively, the included angle between each first diagonal brace and the connecting line of the corresponding sea-side lower hinged point and the corresponding land-side lower hinged point in the first direction is an acute angle, and a first driving device is arranged on each first diagonal brace and is used for adjusting the length of the corresponding diagonal brace. According to the shore crane, the height of the shore crane can be adjusted, and the outreach and the backreach of the shore crane also can be adjusted.

Description

technical field [0001] The invention relates to the technical field of port loading and unloading equipment, in particular to a shore bridge. Background technique [0002] The quay bridge, also known as the quayside container crane, the main structure is composed of the door frame column, the girder and the upper structure (the part above the girder, including the upper beam, ladder frame, tie rod, machine room) and so on. The door frame column is a fixed frame composed of steel structure, which plays a supporting role for the upper structure; a cart traveling mechanism is installed under the door frame column, which can realize the movement of the quay bridge as a whole along the direction parallel to the coastline. A girder is suspended under the upper beam on the top of the pillar of the door frame on the sea and land sides, and the trolley can move along the track laid on the girder. The movement of the whole machine along the direction of the cart, the movement of the ...
