[0002] An eccentric plate joint is a metal connector consisting of two vertical or nearly vertical metal plates connected by bolts or welding. The center of one plate is eccentric to the edge of the other plate, giving the structure good seismic performance. Therefore, eccentric plate joints have been widely used in construction, bridges and other fields.
[0003] During the construction of buildings or bridges, it is often necessary to hoist eccentric plates to install them in the required positions. Current methods for hoisting eccentric plates typically involve welding lifting lugs onto the plates and using these lugs for the hoisting operation.
[0004] However, in the existing methods of hoisting eccentric plates, the lifting lugs need to be cut and disassembled after the hoisting work is completed, which leads to cumbersome and complicated operations and is prone to damaging the structure of the plate itself. Utility Model Content
[0005] To address the technical problem in the prior art that hoisting eccentric plates requires welding lifting lugs onto the plates and then cutting and disassembling them after hoisting, resulting in cumbersome and complex operations that can easily damage the structure of the plates themselves, this utility model provides an eccentric plate hoisting fixture and hoisting system.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] In the first aspect, this utility model provides an eccentric plate lifting fixture for lifting eccentric plates, wherein the eccentric plates include long plates and short plates that are perpendicular to each other, and the eccentric plate lifting fixture includes at least two connecting components and slings.
[0008] The connecting component is provided with a connecting hole and a mounting slot;
[0009] The connecting hole is connected to the sling;
[0010] When hoisting the eccentric plate, the short plate is inserted into the mounting slot;
[0011] When the short plate is inserted into the mounting slot, the long plate is directly below the connecting hole.
[0012] Optionally, the eccentric plate hoisting fixture further includes a movable limiting member, which is detachably mounted on the connecting assembly and positioned close to the mounting slot;
[0013] When the short plate is inserted into the mounting slot, the movable limiting member limits the eccentric plate.
[0014] Optionally, the movable limiting member includes a mounting base and a screw;
[0015] The mounting base is disposed on the connecting assembly near the mounting slot and above the mounting slot;
[0016] The mounting base is provided with a threaded hole, and the screw is inserted into the threaded hole;
[0017] When the short plate is inserted into the mounting slot, the screw moves up and down along the threaded hole to limit the eccentric plate.
[0018] Optionally, the connecting assembly further includes a connector movably disposed in the connecting hole and connected to the sling.
[0019] Optionally, the connector includes a buckle and a connecting rod;
[0020] The connecting rod is inserted into the connecting hole, and both ends of the connecting rod extend out of the connecting hole;
[0021] The buckle is sleeved on both ends of the connecting rod that extend out of the connecting hole;
[0022] The buckle is connected to the sling.
[0023] Optionally, the inner wall of the mounting groove is provided with anti-slip protrusions, which abut against the short plate when the short plate is inserted into the mounting groove.
[0024] Optionally, the anti-slip protrusions are either silicone blocks or rubber blocks.
[0025] Optionally, the connecting component is made of steel.
[0026] Secondly, this utility model provides an eccentric plate hoisting system, which includes a hoisting device and any of the eccentric plate hoisting fixtures described above.
[0027] The eccentric plate lifting operation is installed on the lifting device.
[0028] The beneficial effects of this utility model are:
[0029] (1) This utility model provides a hoisting fixture for eccentric plates, which includes a long plate and a short plate perpendicular to each other. The hoisting fixture includes at least two connecting components and a sling. The connecting components are provided with connecting holes and mounting slots. The connecting holes are connected to the slings. When hoisting the eccentric plate, the short plate is inserted into the mounting slot. When the short plate is inserted into the mounting slot, the long plate is directly below the connecting hole. In this utility model, the short plate of the eccentric plate is inserted and fixed by the mounting slot of the connecting components, and the connecting components are moved by the slings and connecting holes to complete the hoisting of the eccentric plate. This utility model solves the technical problem in the prior art that hoisting eccentric plates requires welding lifting lugs to the eccentric plates and cutting and disassembling them after hoisting, which leads to cumbersome and complicated operation and easily damages the structure of the plate itself.
[0030] (2) At the same time, when the short plate is inserted into the installation slot, the long plate is directly below the connection hole in the hoisting fixture of this utility model. During the hoisting process, the long plate of the eccentric plate is kept in a vertical state, which ensures the stability of the eccentric plate and avoids tilting due to the deviation of the center of gravity of the eccentric plate from the geometric center during the hoisting process, which would bring safety risks to the hoisting work.
[0031] (3) The eccentric plate hoisting fixture in this utility model is also equipped with a movable limiting component on the connecting component. After the short plate of the eccentric plate is inserted into the installation groove, the eccentric plate is limited by the movable limiting component to achieve the reaction force support of the eccentric plate and further reduce the risk of the eccentric plate falling due to instability of the center of gravity during hoisting.

[0048] Firstly, see [the following] Figure 1 , Figure 2 and Figure 3 This diagram illustrates a hoisting fixture for an eccentric plate as described in this application. The fixture is used to hoist an eccentric plate 1, which includes a long plate 11 and a short plate 12 that are perpendicular to each other. The hoisting fixture includes at least two connecting components 2 and a sling 3. The connecting components 2 are provided with connecting holes 21 and mounting grooves 22. The connecting holes 21 are connected to the sling 3. During hoisting of the eccentric plate 1, the short plate 12 is inserted into the mounting groove 22. When the short plate 12 is inserted into the mounting groove 22, the long plate 11 is directly below the connecting hole 21.
[0049] In this embodiment, the eccentric plate lifting fixture includes at least two connecting components 2, which are connected to the sling 3 via connecting holes 21. When lifting the eccentric plate 1, the short plate 12 of the eccentric plate 1 is inserted into the mounting groove 22. When the short plate 12 is inserted into the mounting groove 22, the long plate 11 is directly below the connecting hole 21. In this invention, the short plate 12 of the eccentric plate 1 is inserted and fixed through the mounting groove 22 of the connecting component 2, and the connecting component 2 is moved by the sling 3 and connecting hole 21 to complete the lifting of the eccentric plate 1. This invention solves the technical problem in the prior art where lifting lugs need to be welded onto the eccentric plate 1 during lifting, and then cut and disassembled after lifting, resulting in cumbersome and complex operations that easily damage the structure of the plate itself.
[0050] Meanwhile, in the use of the eccentric plate hoisting fixture of this utility model, when the short plate 12 is inserted into the mounting slot 22, the long plate 11 is directly below the connecting hole 21. During the hoisting process, the long plate 11 of the eccentric plate 1 is kept in a vertical state, which ensures the stability of the eccentric plate 1 and avoids tilting due to the deviation of the center of gravity of the eccentric plate 1 from the geometric center during the hoisting process, thus avoiding safety risks to the hoisting work.
[0051] Specifically, when using the eccentric plate hoisting fixture of this utility model to hoist the eccentric plate, the short plate 12 of the eccentric plate 1 is inserted into the mounting groove 22, and the two connecting components 2 are spaced apart on the short plate 12 of the eccentric plate 1. Preferably, at both ends of the short plate 12, the connecting components 2 are pulled by the slings 3, and the eccentric short plate 1 is hoisted by the connecting components 2 and the mounting groove 22. After the eccentric plate 1 is hoisted to the target position, the short plate 12 is taken out from the mounting groove 22, and the hoisting work is completed.
[0052] Optionally, refer to Figure 5 and Figure 6 The hoisting fixture for the eccentric plate in this utility model also includes a movable limiting member 4, which is detachably mounted on the connecting assembly 2 and located near the mounting groove 22; when the short plate 12 is inserted into the mounting groove 22, the movable limiting member 4 limits the eccentric plate 1.
[0053] In this embodiment, a movable limiting member 4 is provided on the connecting component 2. After the short plate 12 of the eccentric plate 1 is inserted into the mounting groove 22, the movable limiting member 4 is adjusted to limit the eccentric plate 1, so as to realize the reaction force support of the eccentric plate 1 and further reduce the risk of the eccentric plate 1 falling due to instability of the center of gravity during hoisting.
[0054] Specifically, the eccentric plate 1 is supported by the reaction force provided by the active limiting component 4 abutting against the exposed end of the short plate 12.
[0055] Optionally, refer to Figure 6 The movable limiting component 4 in this utility model includes a mounting base 41 and a screw 42. The mounting base 41 is located on the connecting component 2 near the mounting groove 22 and above the mounting groove 22. The mounting base 41 is provided with a threaded hole, and the screw 42 is inserted into the threaded hole. When the short plate 12 is inserted into the mounting groove 22, the screw 42 moves up and down along the threaded hole to limit the eccentric plate 1.
[0056] In this embodiment, the mounting base 41 is located on the connecting component 2 near the mounting groove 22 and above the mounting groove 22; the mounting base 41 is provided with a threaded hole, and the screw 42 is inserted into the threaded hole and can move up and down, thereby limiting the eccentric plate 1.
[0057] Specifically, when using the eccentric plate lifting fixture of this utility model to lift the eccentric plate 1, first move the screw 42 upward along the threaded hole so that the short plate 12 of the eccentric plate 1 can be inserted into the mounting groove 22. After the short plate 12 is inserted into the mounting groove, the two connecting components 2 are spaced apart on the short plate 12 of the eccentric plate 1. Adjust the position of the screw 42 so that the screw 42 descends and abuts against the short plate 12, thus limiting and supporting the short plate 12. Pull the connecting components 2 with the sling 3, and use the connecting components 2 and the mounting groove 22 to lift the eccentric short plate 1. After lifting the eccentric plate 1 to the target position, adjust the position of the screw 42 and remove the short plate 12 from the mounting groove 22 to complete the lifting operation.
[0058] Optionally, refer to Figure 4 and Figure 7 The connecting component 2 in this utility model also includes a connector 23, which is movably disposed in the connecting hole 21 and is connected to the sling 3.
[0059] In this embodiment, the sling 3 is connected to the connector 23 to avoid the problem of difficulty in disassembly caused by the sling 3 passing directly through the connection hole 21.
[0060] Optionally, refer to Figure 7 The connector 23 in this utility model includes a buckle 231 and a connecting rod 232; the connecting rod 232 is inserted into the connecting hole 21, and both ends of the connecting rod 232 extend out of the connecting hole 21; the buckle 231 is sleeved on both ends of the connecting rod 232 extending out of the connecting hole 21; the buckle 231 is connected to the sling 3.
[0061] In this embodiment, the connecting rod 231 is inserted into the connecting hole 21 and connected to the sling 3 via the buckle 231. During the hoisting of the eccentric plate 1, the movable connection between the connecting rod 231 and the connecting hole 21 allows relative rotation between the connecting assembly 2 and the connecting piece 23, thereby ensuring the stability of the eccentric plate 1 and reducing safety risks during transportation.
[0062] Furthermore, the connecting rod 231 is provided with threads and fasteners. The fasteners are sleeved on the connecting rod 231, and the retaining ring 232 is installed on the connecting rod 231 by the fasteners. During use, when it is necessary to lift eccentric plates 1 of different thicknesses and lengths, the connecting component 2 can be disassembled and replaced by the fasteners to adapt to the lifting operation of different eccentric plates.
[0063] Optionally, refer to Figure 8 The inner wall of the mounting groove 22 in this utility model is provided with anti-slip protrusions 24. When the short plate 12 is inserted into the mounting groove 22, the anti-slip protrusions 24 abut against the short plate 12.
[0064] In this embodiment, anti-slip protrusions 24 are provided on the inner wall of the mounting groove 22. The anti-slip protrusions 24 generate friction with the short plate 12, thereby further enhancing the stability of the eccentric plate 1 during hoisting and preventing it from falling off.
[0065] It should be noted that those skilled in the art can select the position and number of the anti-slip protrusions 24 according to actual usage needs, and no specific limitation is made in this embodiment.
[0066] Optionally, the anti-slip protrusion 24 in this invention can be either a silicone block or a rubber block.
[0067] In this embodiment, the anti-slip protrusion 24 is either a silicone block or a rubber block, which has a strong frictional force with the eccentric plate 1 and will not cause wear to the short plate 12 of the eccentric plate 1.
[0068] Optionally, the connecting component 2 in this utility model is made of steel.
[0069] In this embodiment, the connecting component 2 is made of steel, which has the advantages of being wear-resistant, corrosion-resistant, impact-resistant, easy to manufacture, and inexpensive.
[0070] Secondly, this utility model also provides an eccentric plate hoisting system, which includes hoisting devices and any one of the above eccentric plate hoisting fixtures; the eccentric plate hoisting fixture is installed on the hoisting device.
[0071] In this embodiment, an eccentric plate hoisting system is provided. It should be noted that the eccentric plate hoisting fixture in this embodiment has the same specific structure, implementation method and beneficial effects as the eccentric plate hoisting fixtures described above, so it will not be described again.
