Description

Technical Field

[0001] The utility model relates to the technical field of crane hooks, in particular to a crane hook. Background Art

[0002] A crane is a device used for vertical lifting and horizontal transport of heavy objects. It is widely used in various material handling and construction scenarios. For example, cranes are used to lift heavier materials or products during the transportation and processing process.

[0003] A crane is generally composed of a track, a winding machine (electric hoist), a wire rope and a hook. When in use, the material or product to be lifted is hung on the hook, and then the winding machine drives the wire rope to be retracted and released, which can drive the hook and the suspended product to rise and fall, and then it can be transported to the required position as a whole through the track. In this way, the lifting can be completed.

[0004] However, when the current hooks are used in conjunction with cranes, the hooks are generally single hooks. When lifting larger products or materials, the lifting is prone to instability. If double hooks are required, it is necessary to purchase double hooks separately. After damage, the entire hook needs to be replaced. It is inconvenient for users to temporarily choose to use double hooks or single hooks according to their own needs, and the adaptability is poor. Utility Model Content

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the examples of this application, please refer to Figure 1 A crane hook comprises a fixing plate 10 with a fixing shell 11 fixed on the top, a fixing shaft 12 is fixed inside the fixing shell 11, a wire wheel 13 is rotatably connected to the outside of the fixing shaft 12, the wire wheel 13 can be a wheel body for connecting the existing hook to the crane wire rope, the wire wheel 13 is used for winding the wire rope, when in use, the wire rope of the crane is wound around the wire wheel 13 in an existing way to complete the connection of the hook, and this step is the same as the connection method of the existing crane hook;

[0041] Furthermore, a hook 30 is provided at the bottom of the fixed plate 10, and a limiting column 51 is fixed to the same end of the front and rear sides of the fixed plate 10, and a rotating shaft 52 is fixed to the other end. The outside of the rotating shaft 52 is rotatably connected to a rotating plate 53, and a limiting groove 54 adapted to the limiting column 51 is provided on one side of the rotating plate 53. After two hooks of the present application are combined, a plurality of latches 40 are inserted between the two combined fixed plates 10. When in use, if the user only needs to use one hook, it is sufficient to connect one hook of the present application normally. When multiple hooks are needed, such as two hooks, then Figure 1 The two hooks are assembled in a manner and limited by the latch 40. When approaching, the rotating plate 53 is first rotated upward to align with the top of the connected limiting column 51. After approaching, the rotating plate 53 is lowered to allow the limiting column 51 to enter the inside of the limiting groove 54, and the two hooks can be assembled (conversely, they can be disassembled). Then, the wire rope of the crane is connected to the wire wheels 13 of the two hooks in the existing manner, so as to adapt to the situation where two hooks need to be used. Similarly, multiple hooks can be connected, and operation and detection are better adaptable. There is no need to purchase them separately. Only one hook of the present application is needed for combination, which is more convenient to use.

[0042] Furthermore, a plurality of sockets are fixed on both sides of the fixing plate 10 , and the sockets are adapted to the plugs 40 for connecting the plugs 40 .

[0043] For further information, see Figure 1 The connection structure between the fixed plate 10 and the hook 30 includes two support plates 21 fixed to the bottom of the fixed plate 10, one end of a connecting rod 22 is rotatably connected between the two support plates 21, and connecting plates 23 are fixed on both sides of the other end of the connecting rod 22. A cross plate 24 is fixed between the two connecting plates 23, one end of the hook 30 can rotatably pass through the cross plate 24, and a limit plate 25 is fixed at the end, as shown in detail. Figure 1 As shown, a plane bearing is provided between the limit plate 25 and the cross plate 24, and when necessary, the connecting rod 22 can be used for the hook 30 to rotate forward and backward, and the hook 30 can rotate at the same time.

[0044] For further examples, see Figure 1 and 2A connecting frame 60 is further provided on the top of the two combined fixing plates 10 for fixing. Specifically, the connecting frame 60 includes two connecting sleeves 61 fixed on both sides of the top of the fixing shell 11. After the two fixing plates 10 are combined, the two adjacent connecting sleeves 61 are close to each other and are cylindrical after the combination. A threaded column 62 is provided on the top of the two combined connecting sleeves 61. A connecting column 63 extending to the inside of the connecting sleeve 61 is fixed at the bottom of the threaded column 62. A limiting block 64 located inside the connecting sleeve 61 is fixed at the bottom of the connecting column 63. A groove is provided inside the two combined connecting sleeves 61, and the groove is adapted to the combination of the connecting column 63 and the limiting block 64. The external thread sleeve of the threaded column 62 is connected with a fixing sleeve 65, and a locking sleeve 66 is fixed to the bottom of the fixing sleeve 65. The locking sleeve 66 is sleeved on the outside of the two combined connecting sleeves 61. When the combination is no longer needed, the fixing sleeve 65 is twisted to drive the fixing sleeve 65 to move up, and the locking sleeve 66 can be driven to move up, so that the fixing sleeve 65 and the locking sleeve 66 can be removed, and then the rotating plate 53 is turned to make the limiting column 51 away from the limiting groove 54, and the fixed shell 11 is separated from the left and right. At this time, the threaded column 62, the connecting column 63 and the limiting block 64 can be removed to complete the separation. Conversely, they can be installed. The operation is simple, which is convenient for users to disassemble and assemble the hook, and has better adaptability.

[0045] Furthermore, the top diameter of the two combined connecting sleeves 61 is smaller than the bottom diameter, and the inner wall of the locking sleeve 66 is in close contact with the connecting sleeve 61, so that when tightening, the stability after locking can be increased through the influence of the conical surface.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
