Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, and specifically to a dual-purpose lifting hook adapter. Background Technology
[0002] In daily production processes, cranes typically need to be connected to lifting equipment for hoisting operations. With technological advancements and increasing efficiency requirements, automated cranes have become more prevalent in the industry. However, for unmanned cranes requiring high positioning accuracy, the traditional method of connecting the crane and lifting equipment involves linking the hook to the lifting trunnion. The hook's curved shape results in line contact with the trunnion, and a significant gap exists between the hook's side and the lifting trunnion's trunnion. This leads to considerable relative sway between the lifting equipment and the hook, which is insufficient for achieving the required positioning accuracy in unmanned crane applications. Utility Model Content
[0003] The purpose of this utility model is to provide a dual-purpose hook adapter to address the problems existing in the background technology.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] A dual-purpose hook adapter includes a first structural plate, a second structural plate on one side of the first structural plate, a connecting plate between the first and second structural plates, a first mounting hole at the bottom of the first structural plate, a second mounting hole corresponding to the first mounting hole on the second structural plate, and a hanging plate on each side of the connecting plate that is mirror-image of each other. The hanging plate has a hanging groove for hanging a steel wire rope.
[0006] Furthermore, the upper part of the first structural plate is provided with a first insertion hole, and the second structural plate is provided with a second insertion hole corresponding to the first insertion hole.
[0007] Furthermore, the hanging plate is provided with a through hole near the upper part of the hanging groove, and a rotating shaft is provided in the through hole. Both ends of the rotating shaft extend out of the through hole, and a stop bar is fixed at each end of the rotating shaft. An end bar is connected between the stop bars, and the end bar is located at the end of the stop bar away from the rotating shaft. The end bar abuts against the lower part of the hanging groove.
[0008] Furthermore, the second structural plate is arranged parallel to the first structural plate.
[0009] Furthermore, the first structural plate and the connecting plate are arranged perpendicular to each other.
[0010] Furthermore, the first structural plate is arranged vertically.
[0011] The beneficial effects of this utility model are as follows: The structural plate and hanging plate are provided, and the device is connected to the crane pulley block via the structural plate. When installing the lifting device, the lifting shaft is installed in the mounting hole, which effectively prevents the lifting device from swaying and improves lifting accuracy compared to traditional methods. A wire rope can be connected via the hanging plate, allowing for the use of the wire rope to lift other materials. This method is convenient, facilitates on-site operations, and improves lifting efficiency. The structure is simple and the method of use is convenient. Attached Figure Description

Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings:
[0016] like Figure 1 and 2As shown, a dual-purpose hook adapter includes a vertically arranged first structural plate 1, a second structural plate 2 parallel to the first structural plate 1 on one side, a connecting plate 3 perpendicular to the first structural plate 1 between the first structural plate 1 and the second structural plate 2, the first structural plate 1 and the second structural plate 2 having the same length, and the connecting plate 3 having a shorter length than the first structural plate 1. The bottom of the first structural plate 1 has a first mounting hole 4, and the second structural plate 2 has a second mounting hole 5 corresponding to the first mounting hole 4. When lifting clamps or other lifting tools are needed, the lifting shaft of the clamps or other lifting tools can be passed through the first mounting hole 4 and the second mounting hole 5. The diameters of the first mounting hole 4 and the second mounting hole 5 are adapted to the diameter of the lifting shaft of the lifting tool. Each side of the connecting plate 3 has a mirror-image hanging plate 6, with a hanging groove 7 for hanging wire ropes. The upper part of the hanging plate 6 near the hanging groove 7... A through hole 8 is provided at the location, and a rotating shaft 9 is installed inside the through hole 8. The rotating shaft 9 can rotate within the through hole 8. Both ends of the rotating shaft 9 extend out of the through hole 8, and a stop rod 10 is fixed at each end of the rotating shaft 9. The stop rods 10 have a triangular structure and are arranged parallel to each other. The stop rods 10 are used to block the hanging groove 7 and prevent the wire rope in the hanging groove 7 from coming out of the hanging groove 7. The stop rods 10 can rotate around the rotating shaft 9 as the center line. An end rod 1 connects the stop rods 10. 1. The end rod 11 is located at the end of the stop rod 10 away from the rotating shaft 9. The end rod 11 can abut against the lower part of the hanging groove 7 under the action of gravity, so that the end rod 11 always stays against the lower part of the hanging groove 7. The upper part of the first structural plate 1 is provided with a first insertion hole 12, and the second structural plate 2 is provided with a second insertion hole 13 corresponding to the first insertion hole 12. When in use, the connecting shaft can be inserted into the first insertion hole 12 and the second insertion hole 13 to connect the connecting shaft to the ear plate at the bottom of the crane pulley block.
[0017] The method of using this utility model is as follows:
[0018] In use, the device can first be connected to the bottom of the crane's pulley block. Specifically, a connecting shaft is inserted into the first insertion hole 12 and the second insertion hole 13. Then, the two ends of the connecting shaft are connected to the ear plates at the bottom of the crane's pulley block. If wire rope is used for hoisting, the existing conventional method can be used to connect the wire rope to the object to be hoisted. Then, the wire rope is suspended in the hoisting groove 7. When hoisting, first press the stop bar 10 to make the stop bar 10 rotate and expose the hoisting groove 7. Then, the wire can be hung in the hoisting groove 7. After the wire is hung, the stop bar 10 rotates under the action of gravity, so that the end bar 11 abuts against the lower part of the hoisting groove 7, and the hoisting groove 7 is resealed. This is convenient and quick, and then hoisting can be carried out.
[0019] When other lifting tools, such as clamps, are needed for lifting, the lifting shaft of the lifting tool can be passed through the first mounting hole 4 and the second mounting hole 5 to connect the lifting tool to this device. Because the lifting shaft of the lifting tool is installed in the first mounting hole 4 and the second mounting hole 5, compared with the traditional method, it can effectively prevent the lifting tool from swaying and improve the lifting accuracy. It can be used to lift materials by suspending clamps and other lifting tools with a crane, and it can also be used as a hook to hang wire ropes to lift other materials. The method of use is convenient, facilitates on-site operations, and improves lifting efficiency.
