[0040] 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.

[0041] 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, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0042] In order to make the purpose, technical scheme and advantages disclosed in the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention and are not used to limit the embodiments of the present invention. The acquisition, storage, use, and processing of data in the technical scheme of the embodiments of the present invention are in compliance with the relevant provisions of national laws and regulations.

[0043] Next, a quay crane according to an embodiment of the present invention will be described.

[0044] like Figures 1 to 4 As shown, the quay crane of this embodiment includes: a front beam 100, a safety pin pulling pile 200, a ladder frame 300, a guide section assembly 400 and a safety pin 500.

[0045] First, the front beam 100 and the shear pin pulling pile 200 will be described.

[0046] The front beam 100 is a common component of the quay crane, and will not be described in detail here. The safety pin pull pile 200 is connected to the front beam 100.

[0047] The safety pin pull pile 200 includes a base 210, two anti-wear blocks 212 and a vertical plate 220. The base 210 is formed as a hollow cuboid, and its bottom is connected to the front beam 100. The two anti-wear blocks 212 are respectively arranged on two outer webs 211 of the base 210 facing the guide segment assembly 400. The vertical plate 220 is vertically connected to the top plate 214 on the upper surface of the base 210, and the safety pin pull pile 200 is anchored to the anchor seat through the vertical plate 220.

[0048] The base 210 of the hollow cuboid can make the safety pin pull pile 200 have high strength while being low in weight, thereby increasing the stability of the quay crane. The hollow cuboid may include a box structure.

[0049] If the safety pin pile 200 and the guide segment assembly 400 interfere and collide, the base 210 of the safety pin pile 200 and the guide segment assembly 400 will be damaged. By providing the wearable anti-wear block 212, if a collision occurs, only the anti-wear block 212 and the guide frame will collide, and only the anti-wear module will be worn, and the anti-wear module can be replaced. In this way, the stability and life of the quay crane can be increased.

[0050] The vertical plate 220 of the safety pin pull pile 200 is anchored to the anchor seat of the ladder frame 300. Thus, the front beam 100 can be fixed to the ladder frame 300 at a predetermined angle (eg, 80 degrees) through the safety pin pull pile 200.

[0051] Next, the ladder frame 300 is described. The ladder frame 300 includes an anchor seat, and the anchor seat cooperates with the safety pin pull pile 200.

[0052] By providing an anchor seat, the fixation of the safety pin pulling pile 200 can be facilitated.

[0053] Next, the guide segment assembly 400 will be described. The guide segment assembly 400 is connected to the top of the ladder frame 300 and is disposed on both sides of the safety pin pulling pile 200.

[0054] The guide section assembly 400 can prevent the front beam 100 from tilting up and shaking greatly to the left and right, thereby making the fixation between the front beam 100 and the ladder frame 300 smoother and more stable.

[0055] Finally, the safety pin 500 is described. The safety pin 500 connects the anchor seat and the safety pin pulling pile 200 so that the anchor seat and the safety pin pulling pile 200 are anchored.

[0056] The anchor seat is anchored to the safety pin pull pile 200 by the safety pin 500 , so that the connection between the safety pin pull pile 200 and the anchor seat can be more firmly established, thereby enabling the front beam 100 to be more stably fixed on the ladder frame 300 .

[0057] In the above quay crane, the front beam 100 is tilted up at a certain angle (for example, 80 degrees), and the safety pin pile 200 connected to the front beam 100 is connected to the guide section assembly 400 on the ladder frame 300. The safety pin 500 is used to anchor the vertical plate 220 of the safety pin pile 200 to the anchor seat of the ladder frame 300, so that the front beam 100 and the ladder frame 300 are fixed. The hollow rectangular base 210 of the safety pin pile 200 can make its structure stable and relatively light in weight. A wearable anti-module is provided to avoid collision and friction between the safety pin pile 200 and the guide section assembly 400 due to direct interference. In this way, the front beam 100 can be stably fixed on the ladder frame 300, avoiding collision and wear between the base 210 of the safety pin pile 200 and the guide section assembly 400, and increasing the service life.

[0058] According to some embodiments of the present invention, the quay bridge further comprises two bottom plates 215. The two bottom plates 215 are respectively arranged on the side of the two outer webs 211 facing away from the anti-wear blocks 212, the positions of the bottom plates 215 correspond to the positions of the anti-wear blocks 212, and the area of ​​the bottom plates 215 is larger than the area of ​​the anti-wear blocks 212.

[0059] By adding the bottom plate 215, the outer web 211 can be prevented from being penetrated during the collision between the anti-wear module and the guide segment assembly 400, or during the replacement of the anti-wear block 212. Thus, the strength of the base 210 can be increased, and the situation of structural non-sealing caused by penetration can be avoided.

[0060] Furthermore, the quay bridge further comprises a guide block 213. The guide block 213 is arranged on the outer web 211 and adjacent to the anti-wear block 212. The guide block 213 is formed with an inclined surface on one side facing the guide block assembly, and its height is higher than that of the anti-wear block 212.

[0061] The guide block 213, which is higher than the anti-module, will interfere with and collide with the guide segment assembly 400 before the anti-module. Since the guide block 213 is a sloped structure, the top of the slope will contact the guide segment assembly 400 first, and the contact area is relatively small. Therefore, even if there is interference contact, the front beam 100 can continue to be raised, and it is avoided that only the anti-module directly collides with the guide segment assembly 400, the contact area is relatively large, the friction force is relatively large, and the anti-module and the guide segment assembly 400, that is, the front beam 100, may be stuck.

[0062] According to some embodiments of the present invention, a mounting hole is formed on the upper portion of the vertical plate 220, and the vertical plate 220 is anchored to the ladder frame 300 through the mounting hole.

[0063] For example, Figure 3 The rectangular mounting hole of the middle vertical plate 220 can be locked with the anchor seat of the ladder frame 300 more conveniently.

[0064] Furthermore, the quay bridge further includes a reinforcing plate 230 . One end of the reinforcing plate 230 is connected to the vertical plate 220 , and the other end thereof is connected to the base 210 .

[0065] The vertical plate 220 and the base 210 are connected by the reinforcing plate 230 , so that the connection between the vertical plate 220 and the base 210 can be more stable.

[0066] According to some embodiments of the present invention, the gap between the anti-wear block 212 and the guide segment assembly 400 ( Figure 4 The distance A is greater than 15 mm. A gap greater than 15 mm can reduce the probability of collision between the anti-wear block 212 and the guide segment assembly 400.

[0067] The width of the top plate 214 of the base 210 and the width of the guide segment assembly 400 can be adjusted so that the gap between the anti-wear block 212 and the guide segment assembly 400 is greater than 15 mm. This reduces the probability of interference and collision between the anti-wear block 212 and the guide segment assembly 400. For example, if it is found that the gap between the anti-wear block 212 and the guide segment assembly 400 is only 10 mm, which is too small, the width of the top plate 214 can be reduced by 30 mm, and / or the width of the guide segment assembly 400 can be reduced by 20 mm.

[0068] Furthermore, the gap between the base 210 and the guide segment assembly 400 ( Figure 4 The gap greater than 60 mm can prevent the base 210 and the guide segment assembly 400 from directly colliding even when the anti-module is worn, thereby preventing the guide segment assembly 400 and the base 210 from colliding and being damaged.

[0069] As a result, it is possible to effectively avoid collision between the guide segment assembly 400 and the base 210, avoid subsequent high-altitude ignition and paint damage, improve the manufacturing quality of the components, and also be of great benefit to environmental protection.

[0070] Furthermore, the guide segment assembly 400 is connected to the ladder frame 300 by welding.

[0071] The connection is made more stable by welding the guide segment assembly 400 and the ladder frame 300 .

[0072] Furthermore, the tolerance of the position where the guide segment assembly 400 is connected to the ladder frame 300 is 2 to 5 mm.

[0073] The conventional guide segment welding position on the ladder frame 300 has a tolerance of 0 to 2 mm. However, based on the above-mentioned optimized base 210 and guide segment assembly 400 and anti-wear block 212 and guide segment assembly 400, a larger tolerance of 2 to 5 mm can be allowed, thereby making the installation of the guide segment assembly 400 easier.

[0074] Next, a method for installing a quay crane according to an embodiment of the present invention will be described.

[0075] like Figure 5 As shown, the quay crane installation method of the embodiment of the present invention includes: step S1, welding the guide section assembly 400 to the ladder frame 300, and welding the base 210 of the safety pin pull pile 200 to the front beam 100; step S2, raising the front beam 100, and measuring the gap between the guide section assembly 400 and the base 210 of the safety pin pull pile 200; step S3, making an anti-wear block 212 according to the gap between the base 210 and the guide section assembly 400; step S4, restoring the front beam 100 to a horizontal state, and welding the made anti-wear block 212 to a predetermined position of the base 210.

[0076] By measuring the actual gap between the guide section assembly 400 and the base 210 after the front beam 100 is raised, the anti-wear block 212 is made, which can effectively ensure the gap between the anti-wear module and the guide section assembly 400, thereby reducing the probability of interference and collision between the safety pin pull pile 200 and the guide section assembly 400.

[0077] For example, the width of the guide section assembly 400 is shortened by 20 mm, and the guide section assembly 400 is welded to the head platform of the ladder frame 300. When the connecting beam is prefabricated, the newly added anti-wear block 212 box body bottom plate 215 is installed in the box body (the position of the anti-wear block 212 bottom plate 215). After the connecting beam is prefabricated, its level is adjusted, and the safety pin pull pile 200 is welded to the connecting beam according to the pre-marked cross center line and blueprint requirements. The safety pin pull pile 200 connecting beam is assembled to the front beam 100 in the field. When the beam is assembled and debugged, the front beam 100 is tilted to 80°. According to the gap between the safety pin pull pile 200 and the head guide section of the ladder frame 300 after the front beam 100 is pitched on site, the guide plate and the anti-wear block 212 bottom plate 215 are arranged to be made, and welded in place according to the blueprint size. After the anti-wear block 212 is installed and the beam is lifted up by 80°, there is no interference between the safety pin pile 200 and the guide frame, thereby avoiding the displacement of the high-altitude safety pin pile 200 and the cutting of the guide frame head, improving product quality, increasing construction safety, reducing costs, increasing efficiency, and saving energy and protecting the environment.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
