[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0047] Next, a quay crane according to an embodiment of the present invention will be described.

[0048] like Figure 1 and Figure 2 As shown, the quay crane of the embodiment of the present invention includes: a rear beam 110, a land-side upper cross beam 200, a plurality of sets of first ribs 120 and a machine room.

[0049] First, the rear beam 110 and the land side upper cross beam 200 are described. The rear beam 110 includes two parallel boxes, which include a left web plate and a right web plate that are vertically and spaced apart, and an upper wing plate and a lower wing plate connected to the upper and lower ends of the two web plates. The land side upper cross beam 200 is erected above the rear beam 110 and is perpendicular to the rear beam 110. In this way, a stable load-bearing structure can be formed.

[0050] Next, the first ribs 120 are described. A plurality of groups of first ribs 120 are arranged in the box, each group of first ribs 120 includes two adjacent first and second partitions, the top ends of the first and second partitions are connected to the upper wing plate, and the left and right sides thereof are connected to the left and right web plates respectively.

[0051] That is, every two adjacent first partitions and second partitions form a set of first ribs 120. The first partitions and second partitions connect the upper wing plate, the left web plate and the right web plate of the box body, that is, the ribs are supported by the inner wall of the box body. The height of the first partition and the second partition can be 200mm, 300mm, 500mm, etc.

[0052] Finally, the machine room is described. The machine room is arranged on two boxes and adjacent to the upper cross beam 200 on the land side. The machine room includes a main body 310 and a plurality of supports 320 connected to the bottom of the main body 310. The machine room is arranged on the box through the plurality of supports 320. The supports 320 include vertically arranged second ribs 321. Each second rib 321 corresponds to a gap at the top of a first partition and a second partition in a group of first ribs 120.

[0053] The machine room is supported by two parallel boxes of the rear beam 110, and each second rib plate 321 corresponds to a group of first rib plates 120. The second rib plate 321 can be set at the position corresponding to the gap at the top of the first partition plate and the second partition plate, that is, the bottom position of each second rib plate 321 corresponds to the gap at the top of the first partition plate and the second partition plate in a group of first rib plates 120. A second rib plate 321 is supported by the first partition plate and the second partition plate of a group of first rib plates 120. As long as the second rib plate 321 is set at the gap between the first partition plate and the second partition plate of a group of first rib plates 120, the requirement for alignment accuracy is reduced, and the second rib plate 321 is supported by the first partition plate and the second partition plate, so the support strength is higher and the support is more stable.

[0054] In the above quay crane, two mutually parallel boxes of the rear beam 110 carry the machine room, multiple groups of first ribs 120 including adjacent first partitions and second partitions are arranged in the box, one second rib 321 corresponds to a group of first ribs 120, and the second rib 321 is arranged at the gap between the top of the first partition and the second partition of a group of first ribs 120. Thus, the box of the rear beam 110 stably supports the machine room, and multiple groups of first ribs 120 support multiple second ribs 321, which can reduce the positioning accuracy requirements, and the support strength of the machine room is higher and the support is more stable.

[0055] Furthermore, the first partition plate and the second partition plate in each group of first rib plates 120 are inclined toward each other, and the second rib plate 321 is provided corresponding to the top gap between the first partition plate and the second partition plate.

[0056] The two mutually inclined first and second partitions, i.e., the first and second partitions form an "eight" shape. Even if the first and second partitions are deformed, they are inclined at opposite sides, and the tops of the first and second partitions are in contact with each other, so as to prevent the first and second partitions from further deformation, thereby more strongly supporting the second rib plate 321.

[0057] It should be noted that the above are only optional examples, and two adjacent first partitions and second partitions may be arranged in parallel, etc., which should be understood to be within the scope of the present invention.

[0058] Furthermore, a plurality of second ribs 321 are disposed in the support 320 .

[0059] like Figure 2 As shown in FIG. 1 , two second ribs 321 are provided in the support 320. The plurality of second ribs 321 make the support 320 stronger and more stable. Each second rib 321 corresponds to a group of first ribs 120, and the number of groups of first ribs 120 will increase accordingly, thereby making the support of the machine room more stable.

[0060] According to some embodiments of the present invention, the quay bridge further comprises a third rib plate, which is disposed in the support 320 and is perpendicular to the second rib plate 321, and corresponds to the web plate.

[0061] That is to say, the third rib of the support 320 is supported by the web of the box body, thereby making the support for the machine room more stable.

[0062] Furthermore, waist holes are formed in the left and right directions of the support 320 , and the quay bridge also includes bolts, which are connected to the bottom of the main body 310 of the machine room through the waist holes so that the support 320 is connected to the main body 310 .

[0063] A waist hole may be formed on the panel of the support, and the support 320 may be fixed to the main body 310 by passing a screw through the waist hole.

[0064] When the box body is hoisted onto the box body of the rear beam 110, if there is a left-right deviation, the left-right distance of the support 320 can be fine-tuned through the waist hole, so that the left and right positions of the second rib 321 of the support 320 can be more matched with the left and right positions of each group of first ribs 120, and the left and right positions of the third rib and the web of the support 320 can be more matched.

[0065] Next, a method for manufacturing a quay crane according to an embodiment of the present invention is described.

[0066] like Figure 3 As shown, the method for manufacturing a quay crane according to an embodiment of the present invention includes:

[0067] Step S1, setting a first punching hole 210 at the center position of the upper cross beam 200 on the land side.

[0068] That is to say, the land side upper cross beam 200 is used as a reference. By setting the sample punching hole, the reference position can be made clearer and convenient for reference.

[0069] Step S2 , based on the distance from the first punching hole 210 , multiple sets of first ribs 120 are arranged in the box body of the rear beam 110 .

[0070] That is, each group of first ribs 120 is disposed in the box body of the rear beam 110 based on the distance from the first punching hole 210 .

[0071] Step S3, based on the relative positions of the second ribs 321 in the support 320 and the plurality of groups of first ribs 120, the machine room is arranged on two boxes parallel to each other.

[0072] That is to say, the machine room is based on the second ribs 321 in the support 320 to correspond to multiple groups of second ribs 321, so that the machine room is set on two mutually parallel boxes of the rear beam 110.

[0073] The above method for manufacturing a quay crane takes the center of the upper cross beam 200 on the land side as a reference, and sets the first punching hole 210 on the reference. Each group of first ribs 120 is set in the box of the rear beam 110 based on the distance from the first punching hole 210, to ensure the relative position of each group of first ribs 120 and the upper cross beam 200 on the land side, and the machine room is hoisted based on the second ribs 321 in the machine room support 320 corresponding to multiple groups of second ribs 321. The distance between the upper cross beam 200 on the land side and the machine room is very convenient to measure, which is convenient for the precise hoisting of the machine room, and realizes a more precise relative position of each group of first ribs 120 in the box and the second ribs 321 in the support 320 of each box. In addition, the upper cross beam 200 on the land side is used as a reference to avoid interference between the machine room and the upper cross beam 200 on the land side.

[0074] Through the above-mentioned production method, the proportion of the second rib plate 321 of the support 320 in the machine room and the first rib plate 120 in the box of the rear beam 110 has been reduced from the original 100% to 9%, with remarkable results. It avoids a large amount of high-altitude fire rectification work, improves quality and efficiency, and reduces the occurrence of post-painting fire pollution.

[0075] Further, step S2 includes: step S21, connecting the lower wing plate, the left web plate and the right web plate to form a trough body. Step S22, setting each group of first ribs 120 in the trough body based on its distance from the first sample punching 210. Step S23, leading the center line of each group of ribs to the left web plate and the right web plate on both sides of the trough body, and forming a second sample punching. Step S24, covering the upper wing plate so that the trough body becomes a box body, and setting a third sample punching 111 on the upper wing plate according to the second sample punching. In step S3, based on the relative position of the third sample punching 111 and the second rib plate 321, the machine room is set on the two boxes.

[0076] like Figure 5 As shown, a third sample punching hole 111 is set on the upper wing plate at a position corresponding to the first rib plate 120. By setting the sample punching hole on the upper wing plate, the position of the second rib plate 321 can be clearly known, which is convenient for relative positioning with the second rib plate 321 of the support 320, and the position deviation can be found in time and adjusted in time.

[0077] Further, step S3 includes: step S31, setting multiple supports 320 based on the center of the bottom of the main body 310 of the machine room; step S32, adjusting the positions of the multiple supports 320 according to the distance between the third-sample punching holes 111 so that the third-sample punching holes 111 and the second rib plate 321 correspond to each other; step S33 hoisting the machine room and fixing the machine room on the two boxes.

[0078] A plurality of supports 320 are arranged with the center of the bottom of the main body 310 of the machine room as a reference, so as to ensure that the relative position of each support 320 and the machine room is accurate.

[0079] Furthermore, between step S32 and step S33, it also includes: step S34, obtaining the first distance between the left web and the right web and the first punched hole 210 in the left-right direction; step S35, adjusting the positions of the plurality of supports 320 so that the second distance between the second rib 321 of each support 320 and the center of the bottom of the main body 310 in the left-right direction matches the first distance.

[0080] That is to say, based on the first distance between each group of left and right webs and the first punched hole 210, the second distance between each support 320 and the center of the bottom of the machine room is adjusted so that the first distance and the second distance match, thereby making the left and right positions of the second rib plate 321 and the first rib plate 120 accurately aligned, and making the third rib plate of the support 320 correspond to the position of the left and right webs.

[0081] like Figure 6 As shown, the first distance between the left web and the first punch hole 210 is B1, B3, B5, B7, B9, B12, B14, B16, B18, B20, and the first distance between the right web and the first punch hole 210 is B2, B4, B6, B8, B10, B12, B14, B16, B18, B20.

[0082] like Figure 7 As shown, the second distance from the inner side of the rib plate of the support 320 to the center of the bottom of the machine room is C1 and C2, and the second distance from the outer side of the rib plate of the support 320 to the center of the bottom of the machine room is C3 and C4, where B9 corresponds to C3, B10 corresponds to C1, C2 corresponds to B20, and C4 corresponds to B19.

[0083] According to some embodiments of the present invention, the method for manufacturing a quay crane further includes: step S4, a waist hole in the left and right directions is formed on the support 320, and the support is connected to the main body 310 of the machine room by bolts passing through the waist hole, and the position of the support is adjusted within the length range of the waist hole so that the support corresponds to the left web and the right web.

[0084] The position of the support 320 can be fine-tuned through the waist hole, so that the third rib plate in the support 320 corresponds to the left and right webs, and the second rib plate 321 in the support 320 can be more accurately aligned with the left and right positions of the first rib plate 120.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
