Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hanger. Background Art

[0002] With the rise of port machinery upgrades, especially the significant increase in quay crane heightening projects, the demand for lifting operations for quay crane heightening sections has also increased. Currently, lifting operations are generally performed using lifting lugs in conjunction with hooks. The lifting lugs are typically metal rings fixed to the plate units of the quay crane heightening section, providing a lifting point. However, using lifting lugs to lift quay crane heightening sections often presents the following problems: For example, because the center of the lifting point is close to the quay crane heightening section when using the lifting lugs, the hook can easily collide with the quay crane heightening section when approaching the lifting lugs, causing the quay crane heightening section to shake, posing a safety hazard. Furthermore, because the lifting lugs require on-site welding and the welding of reinforcing plates to the interior of the quay crane heightening section's casing, which must then be removed after the lifting is complete, this not only damages the paint on the quay crane heightening section's casing, but also requires a relatively large welding workload.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0031] First, a hanger according to an embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the hanger of the embodiment of the present invention may include: a connecting beam 100, two support frames 200, two positioning plates 300 and two lifting ears 400. The length direction of the connecting beam 100 is consistent with the first direction; the connecting beam 100 is connected to a support frame 200 at both ends along the first direction, the length direction of each support frame 200 is consistent with the second direction, the second direction is perpendicular to the first direction, and the first direction and the second direction are both perpendicular to the vertical direction; each positioning plate 300 is detachably connected to the end of the corresponding support frame 200 away from the connecting beam 100, the two positioning plates 300 are arranged relative to each other so that the quay crane heightened section 101 is located between the two positioning plates 300, and each positioning plate 300 is used to connect to the quay crane heightened section 101; each lifting ear 400 is respectively arranged at the end of the corresponding support frame 200 away from the positioning plate 300.

[0033] In this embodiment, the quay crane heightened section 101 can be first erected and placed in place, and two sets of positioning plates 300 can be symmetrically welded to both sides of the quay crane heightened section 101 according to the positioning lines on the quay crane heightened section 101. Then, the connecting beam 100 and the two support frames 200 can be pre-assembled on the ground, and the two support frames 200 can be used to detachably connect the corresponding positioning plates 300. Then, the shackles and wire ropes can be installed on the two lifting ears 400, and the quay crane heightened section 101 can be lifted using a sling. Therefore, when the quay crane heightened section 101 is lifted by the sling, the sling only needs to be connected to the lifting ears 400 on the support frames 200 that are away from the positioning plates 300. It does not need to be close to the quay crane heightened section 101, and it will not collide with the quay crane heightened section 101, thus preventing the quay crane heightened section 101 from shaking and improving safety. Furthermore, since the two positioning plates 300 are fixedly mounted on the quay crane raised section 101 and can subsequently be installed on the quay crane along with the quay crane raised section 101 without removal, when hoisting the quay crane raised section 101, only the support frame 200 and the positioning plates 300 need to be detachably connected. This avoids damaging the paintwork on the quay crane raised section 101 and reduces welding workload. Furthermore, since the support frame 200 and the positioning plates 300 are detachably connected, the hanger can be reused, reducing operating costs.

[0034] In one embodiment of the present invention, the connecting beam 100 is a box beam, which is light in weight and high in strength, and can effectively improve the structural strength of the hanger.

[0035] like Figure 1 As shown, the connecting beam 100 is provided with first connecting plates 110 at both ends along the first direction, and each support frame 200 is detachably connected to its corresponding first connecting plate 110, such as by screws. As a result, the connecting beam 100 and the two support frames 200 can be quickly assembled at the hoisting site, improving hoisting efficiency.

[0036] like Figure 1 As shown, each support frame 200 includes: a support plate 210, two flange plates 220, and two second connecting plates 230. The length direction of the support plate 210 is consistent with the second direction, and the support plate 210 is detachably connected to the corresponding first connecting plate 110; a flange plate 220 is connected to each end of the support plate 210 in the vertical direction, and the length direction of each flange plate 220 is consistent with the second direction. Figure 3 As shown, each flange plate 220 is provided with a right-angle notch 221 that cooperates with the quay crane elevated section 101 at one end close to the quay crane elevated section 101, and the right-angle notch 221 includes a first end face and a second end face that are connected to each other, the first end face is perpendicular to the second end face, the first end face is parallel to the first direction, and the second end face is parallel to the second direction; each second connecting plate 230 is respectively provided at one end of the corresponding flange plate 220 away from the connecting beam 100, and each positioning plate 300 is respectively detachably connected to the two corresponding second connecting plates 230, and each positioning plate 300 is respectively pressed against the corresponding second end face.

[0037] In other words, the cross section of the support frame 200 can be formed into an I-shape. The I-shaped support frame 200 has a light structure and high lateral rigidity, which can effectively reduce the structural internal force on the quay crane heightened section 101 during lifting. In addition, by providing a right-angle notch 221 that matches the quay crane heightened section 101 at one end of the flange plate 220 close to the quay crane heightened section 101, the second connecting plate 230 and the positioning plate 300 can fully contact and connect, effectively improving the connection strength. In addition, as Figure 1 As shown, the second connecting plate 230 is a right-angled trapezoidal plate. The right-angled trapezoidal plate has a stable structure and can withstand greater pressure, thereby improving the stability of the hanger.

[0038] like Figure 1 As shown, each lifting lug 400 is disposed on the end surface of one of the flange plates 220 facing away from the support plate 210. Each lifting lug 400 is provided with a through hole for a hook to pass through. The length direction of each lifting lug 400 is aligned with the second direction. The hanger also includes two support plates 410, each of which is connected to its corresponding lifting lug 400 and flange plate 220. Each support plate 410 is perpendicular to its corresponding lifting lug 400 and flange plate 220, and the length direction of each support plate 410 is aligned with the first direction. In other words, the support plates 410 and their corresponding lifting lugs 400 have a T-shaped cross-section along the vertical direction. This T-shaped structure has high bending strength and load-bearing capacity, thus preventing deformation during the lifting of the extended quay crane section, effectively improving the stability and service life of the hanger. In addition, the support plates 410 are trapezoidal plates. The trapezoidal plate structure is stable and can withstand high pressure, thereby improving the stability of the hanger.

[0039] like Figure 1 and Figure 3 As shown, the support plate 210, the second end surface, and the two second connecting plates 230 on each support frame 200, facing the side of the quay crane raised section 101, are vertically located in the same plane. In other words, on a support frame 200, the support plate 210 within the right-angled notch 221, the second end surface of the right-angled notch 221, and the second connecting plates 230 all press against the positioning plate 300. This effectively increases the contact area and connection area between the positioning plate 300 and the support frame 200, allowing the positioning plate 300 to be stably connected to the support frame 200, thereby improving the stability of the hanger.

[0040] like Figure 1 As shown, each positioning plate 300 is connected to the two corresponding second connecting plates 230 by fasteners. In other words, the support frame 200 and the positioning plate 300 are detachably connected, so the hanger can be reused, reducing the cost of use.

[0041] like Figure 1 As shown, each support frame 200 further includes a reinforcing plate 201, which is disposed between the two flange plates 220 and is connected to the support plate 210 and the two flange plates 220. Thus, the structural strength of the support frame 200 is effectively improved.
