Description

Technical Field

[0001] The utility model relates to the technical field of shore container cranes, and in particular to a shore crane door frame structure and a shore container crane. Background Art

[0002] A quay crane, also known as a shore container crane, is a device that moves a trolley back and forth on a track and uses a sling to load and unload containers on a container ship. Figure 1 and Figure 2 , when the quay crane moves along the direction of the trolley ( Figure 2 When the gantry crane moves in the direction A shown in FIG. 1 , the front beam 1 and the rear beam 2 of the gantry crane will move to the left or right (as shown in FIG. Figure 2 If the lateral deformation of the front and rear beams is too large, it will make it difficult for the trolley operator to position the container in the left and right directions when grabbing and unloading it, which is not conducive to the trolley operator to perform accurate container loading and unloading operations on the quay crane.

[0003] At present, in order to reduce the lateral deformation of the front and rear beams of the quay crane, it is often necessary to increase the thickness and section height of the main beam or column, which greatly increases the weight and manufacturing cost of the quay crane. Therefore, how to reduce the lateral deformation of the quay crane without causing excessive weight increase is very critical and important. Utility Model Content

[0042] Figure 3 FIG. 1 shows a schematic diagram of the structure of a shore container crane 10 provided in this embodiment from a top view. Figure 4 The schematic diagram of the structure of the quay crane door frame structure 100 provided in this embodiment is shown. Figure 3 and Figure 4This embodiment provides a quay crane door frame structure 100 and also provides a shore container crane 10.

[0043] The shore container crane 10 includes a quay crane door frame structure 100 , and the shore container crane 10 may also include other structures of existing quay cranes.

[0044] The quay crane door frame structure 100 includes an upper crossbeam structure 110, a column 120 and a lateral support structure 140. The upper end of the column 120 is fixedly connected to one end of the upper crossbeam structure 110. The lateral support structure 140 is inclined relative to the upper crossbeam structure 110 and the column 120. One end of the lateral support structure 140 is fixedly connected to the upper crossbeam structure 110, and the other end of the lateral support structure 140 is fixedly connected to the column 120. In this way, the upper crossbeam structure 110 and the column 120 are rigidly supported by the lateral support structure 140, so that the lateral deformation of the quay crane in the forward reach and the backward reach can be reduced by about 5% to 10%, thereby improving the problem of lateral deformation of the quay crane. At the same time, no equivalent main beam plate thickness is required, which helps to reduce the weight of the whole machine and the manufacturing cost, and thus facilitates the trolley operator to carry out container loading and unloading operations.

[0045] The quay crane door frame structure 100 provided in this embodiment is further described below:

[0046] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the upper crossbeam structure 110 includes a sea-side upper crossbeam structure 111 and a land-side upper crossbeam structure 112, and the columns 120 include a sea-side column 121 and a land-side column 122. The two ends of the sea-side upper crossbeam structure 111 are respectively fixedly connected with the sea-side columns 121, and the sea-side upper crossbeam structure 111 and the sea-side columns 121 form a sea-side door frame 131; the two sides of the land-side upper crossbeam structure 112 are respectively fixedly connected with the land-side columns 122, and the land-side upper crossbeam structure 112 and the land-side columns 122 form a land-side door frame 132. Specifically, the quay crane door frame structure 100 also includes a connecting crossbeam 133, and the sea-side door frame 131 and the land-side door frame 132 are connected by the connecting crossbeam 133, thereby forming a three-dimensional frame structure.

[0047] Optionally, the lateral support structure 140 can be arranged between the sea-surface upper beam structure 110 and the sea-side column 121, and / or between the land-side upper beam structure 112 and the land-side column 122. Adding the lateral support structure 140 to the sea-surface door frame can reduce the lateral deformation of the front beam, and adding the lateral support structure 140 to the land-side door frame 132 can reduce the lateral deformation of the rear beam 114. Therefore, the setting position of the lateral support structure 140 can be selected according to needs during design, for example, only adding the lateral support structure 140 to the sea-surface door frame, or only adding the lateral support structure 140 to the land-side door frame 132, or adding the lateral support structure 140 to both the sea-surface door frame and the land-side door frame 132.

[0048] In this embodiment, the upper cross beam structure 110 includes an upper cross beam 113 and a rear beam 114 fixedly connected to the upper cross beam 113. One end of the lateral support structure 140 can be connected to the rear beam 114 directly connected to the upper cross beam 113 (such as Figure 4 As shown), one end of the lateral support structure 140 can also be fixedly connected to the rear beam 114 (as shown Figure 5 When the lateral support structure 140 is directly fixed on the rear beam 114, the lateral support structure 140 has a better effect of reducing lateral deformation than when it is fixed on the upper cross beam 113; when the lateral support structure 140 is directly fixed on the upper cross beam 113, the lateral support structure 140 has a smaller impact on the container operation space than when it is fixed on the rear beam 114.

[0049] Figure 6 Shows Figure 4 A schematic diagram of the structure of the lateral support structure 140 in the structure shown, Figure 7 for Figure 6 The structural diagram of the middle B direction, Figure 8 The structure diagram of the support rod insert plate 144 in the lateral support structure 140 provided in this embodiment is shown. Figure 3-Figure 8 In this embodiment, the lateral support structure 140 includes a support body 141, a first connecting plate 145 and a second connecting plate 146. The first connecting plate 145 is fixedly connected to the upper cross beam structure 110, and the second connecting plate 146 is fixedly connected to the column 120. One end of the support body 141 is fixedly connected to the upper cross beam structure 110 and the first connecting plate 145, and the other end of the support body 141 is fixedly connected to the column 120 and the second connecting plate 146.

[0050] Specifically, the first connecting plate 145 is fixedly welded to the web of the upper cross beam 113, and the second connecting plate 146 is fixedly welded to the web of the column 120. The supporting body 141 is a rod-shaped member, one end of which is welded to the upper cross beam structure 110 and the first connecting plate 145 in the length direction, and the other end of which is welded to the column 120 and the second connecting plate 146 in the length direction.

[0051] Optionally, there are two first connecting plates 145, and the two first connecting plates 145 are welded to the upper cross beam 113 at intervals. One end of the support body 141 is located between the two first connecting plates 145, and both sides of the end of the support body 141 are respectively welded to the first connecting plates 145. At the same time, the end surface of the end of the support body 141 is welded to the upper cross beam structure 110.

[0052] It should be noted that the connection structure between the lateral support structure 140 and the upper cross beam 113 and the rear beam 114 is basically the same and will not be elaborated here. However, since the direction of the connection position between the lateral support structure 140 and the upper cross beam 113 is different from the direction of the connection position between the lateral support structure 140 and the rear beam 114, the structure of the first connecting plate 145 can be fine-tuned accordingly.

[0053] Optionally, there are two second connecting plates 146, which are welded to the column 120 at intervals, and the other end of the support body 141 is located between the two second connecting plates 146, and both sides of the end of the support body 141 are respectively welded to the second connecting plates 146. At the same time, the end surface of the end of the support body 141 is welded to the column 120.

[0054] Optionally, the first connecting plate 145 and the second connecting plate 146 are roughly triangular in shape, one side edge of the first connecting plate 145 is flush with the upper beam structure 110 and welded to the upper beam structure 110 , and one side edge of the second connecting plate 146 is flush with the column 120 and welded to the column 120 .

[0055] Furthermore, the support body 141 includes a main support rod 142 and a support rod plug-in plate 144 installed at both ends of the support rod. The support rod plug-in plate 144 is plugged and fixed on the main support rod 142, and the two ends of the main support rod 142 are respectively connected to the upper crossbeam 113 and the column 120 through the support rod plug-in plate 144.

[0056] Specifically, the support rod insert 144 is a plate-shaped member, and the shape of the plate-shaped member is as follows: Figure 8 A support rod insert plate 144 is provided at the end of the support body 141 , so that the support body 141 is connected to the upper crossbeam structure 110 or the column 120 through the support rod insert plate 144 . Fig. 9 The schematic diagram of the structure of the welding point between the lateral support structure 140 and the upper crossbeam structure 110 is shown. Figure 3-Figure 9The support rod plug plate 144 has two opposite sides, one side of which is a connecting portion 1444, which is welded and fixed to the upper crossbeam structure 110 or the column 120 through the connecting portion 1444, that is, the connecting portion 1444 of the support rod plug plate 144 arranged at one end of the main support rod 142 is welded and fixed to the upper crossbeam structure 110, and the connecting portion 1444 of the support rod plug plate 144 arranged at the other end of the main support rod 142 is welded and fixed to the column 120; the other side of the support rod plug plate 144 is an inserting portion 1441, which is inserted and positioned with the main support rod 142 through the inserting portion 1441.

[0057] It should be noted that Fig. 9 In the structure shown, the lateral support structure 140 is connected to the upper beam 113 of the upper beam structure 110, so the first connecting plate 145 is welded and fixed to the upper beam 113, and accordingly, the connecting portion 1444 of the strut plug plate 144 is welded and fixed to the upper beam 113 of the upper beam structure 110. It can be understood that when the lateral support structure 140 is connected to the rear beam 114 of the upper beam structure 110, the first connecting plate 145 is welded and fixed to the rear beam 114, and similarly, the connecting portion 1444 of the strut plug plate 144 is welded and fixed to the rear beam 114 of the upper beam structure 110.

[0058] The support rod plug plate 144 also has a first end 1447 and a second end 1448 relative to each other, and the first end 1447 and the second end 1448 are welded and fixed to the first connecting plate 145 or the second connecting plate 146, that is, the first end 1447 and the second end 1448 of the support rod plug plate 144 installed at one end of the main support rod 142 are respectively welded and fixed to the first connecting plate 145, and the first end 1447 and the second end 1448 of the support rod plug plate 144 installed at the other end of the main support rod 142 are respectively welded and fixed to the second connecting plate 146.

[0059] Optionally, the cross-section type of the main support rod 142 can be set to a circular tube cross-section (such as Fig. 10A As shown), box section (as shown Fig. 10B as shown) or I-beam section (as shown Fig. 10C shown).

[0060] Optionally, the plug-in portion 1441 includes two plug-in arms 1442 arranged at intervals and a first arc groove 1443 located between the two plug-in arms 1442. The end of the main support rod 142 is provided with a plug-in groove 143, the plug-in portion 1441 is plugged into the plug-in groove 143, and the two plug-in arms 1442 are located on both sides of the main support rod 142. The plug-in arms 1442 are welded and fixed to the main support rod 142, so that the load of the main support rod 142 can be fully transferred to the support rod plug plate 144.

[0061] Optionally, a second arc groove 1446 is provided in the middle of the connecting portion 1444 of the support rod plug plate 144, and the connecting portion 1444 forms connecting arms 1445 on both sides of the second arc groove 1446, respectively, and the connecting arms 1445 are welded and fixed to the upper beam structure 110 or the column 120. In other words, the middle portion of the side of the support rod plug plate 144 is not welded and fixed to the upper beam structure 110 or the column 120.

[0062] The quay crane door frame structure 100 and the shore container crane 10 provided by the embodiment of the utility model are provided with a lateral support structure 140 between the upper crossbeam structure 110 and the column 120, and the structure of the lateral support structure 140 is set, so that the load of the upper crossbeam structure 110 can be finally transmitted to the column 120 through the first connecting plate 145, the support rod plug plate 144 at one end of the main support rod 142, the main support rod 142, the support rod plug plate 144 at the other end of the main support rod 142 and the second connecting plate 146 respectively. On the contrary, the load of the column 120 can also be transmitted to the upper crossbeam structure 110, thereby increasing the load transmission path, achieving the effect of increasing the lateral stiffness of the quay crane, and further reducing the lateral deformation of the quay crane at the forward reach and the rear reach by about 5%-10%, which can achieve the effect of reducing the thickness of the main beam plate, reducing the weight of the whole machine and the manufacturing cost, and facilitating the trolley operator to carry out container loading and unloading operations.

[0063] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in this field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
