[0002] Cranes are important equipment widely used in engineering construction, logistics and transportation, manufacturing and other fields. Their main function is to use hooks and wire ropes to achieve vertical lifting and horizontal movement of heavy objects. In the operating mechanism of the crane, the hook group pulley is a key component, which realizes the lifting and lowering of heavy objects by cooperating with the wire rope. The hook group pulley is usually composed of several pulleys, among which the most critical one is the receiving wheel, which is in direct contact with the wire rope and bears the weight of the heavy object. Therefore, the receiving wheel must have sufficient strength and wear resistance, and at the same time, it must ensure a good match with the wire rope to avoid problems such as slipping or rope slipping. However, the existing crane hook group pulley has some inconveniences in installation and maintenance, especially in the connection and fixation between the receiving wheel and the wire rope, which often requires the use of special tools or clamps, and the operation is cumbersome, time-consuming and labor-intensive, and the reliability and stability of the connection cannot be guaranteed, which greatly affects the efficiency and safety of the crane and brings inconvenience to the operator.

[0028] See also Figure 1-5 A crane hook group pulley installation structure includes a receiving wheel 1, which is connected to a steel wire rope. The receiving wheel 1 is provided with a connecting mechanism, which includes a center rod 2, a receiving sleeve 3, an insertion tube 4, a hexagonal sleeve 5, a limiting ring 6, an elastic sheet 7, an abutment head 8, a limiting mechanism and a receiving mechanism. The receiving sleeve 3 is slidably connected to the center rod 2, and the receiving sleeve 3 fits in the receiving wheel 1. Insertion tubes 4 are respectively installed at both ends of the center rod 2. Limiting rings 6 are installed in the hexagonal sleeve 5. The limiting ring 6 is slidably connected to the insertion tube 4. An internal groove 9 is opened in the hexagonal sleeve 5, and a spiral groove 10 is opened on the inner wall of the insertion tube 4. A plurality of elastic sheets 7 are provided, and the plurality of elastic sheets 7 are respectively installed in the internal groove 9 along the spiral groove 10. On, each elastic sheet 7 is equipped with a contact head 8, the contact head 8 is pressed on the spiral groove 10, the limiting mechanism is installed on the hexagonal sleeve 5, the receiving mechanism is installed on the center rod 2, the limiting mechanism includes a threaded sleeve 11 and a hexagonal section 12, the threaded sleeve 11 is threadedly connected to the hexagonal sleeve 5, the hexagonal section 12 is installed on the threaded sleeve 11, the insertion tube 4 is rotatably connected in the threaded sleeve 11, a plurality of compression springs 13 are equidistantly provided on the hexagonal section 12, each compression spring 13 is provided with a round head 14, a plurality of insertion holes 15 are equidistantly provided on the hexagonal sleeve 5, an insertion rod 16 is slidably provided in each insertion hole 15, a limiting plate 17 is provided on the insertion rod 16, a hexagonal groove 18 is provided on the limiting plate 17, and the hexagonal groove 18 is stuck on the hexagonal section 12.

[0029] In this embodiment, when it is necessary to quickly install the hexagonal sleeve 5 on the insertion tube 4, the insertion tube 4 is first slidably connected to the threaded sleeve 11 and the limiting ring 6. Due to the unidirectional setting of the multiple elastic sheets 7, it can be quickly pushed open, and the contact head 8 does not need to move along the rotation direction of the spiral groove 10, and can directly slide until the round head 14 is pressed against the side plate 19. Then, by rotating the hexagonal sleeve 5 for tightening, the compression spring 13 and the round head 14 are stably in contact with the side plate 19, thereby ensuring a quick fixing process. Since the insertion rod 16 is in the insertion hole 15, the limiting plate 17 can be fixed, and the hexagonal groove 18 on the limiting plate 17 is stuck on the hexagonal section 12, so that the threaded sleeve 11 can be fixed, thereby ensuring the stability of the fixation. When it needs to be released, it only needs to be rotated along the spiral groove 10 to release the connection between the two.

[0030] See also Figure 1 and Figure 2As an implementation method of a crane hook group pulley installation structure for a receiving mechanism: the receiving mechanism includes side plates 19 and fixing bolts 20, the center rod 2 is rotatably connected to the two side plates 19, the fixing bolts 20 are connected to the two side plates 19, the round head 14 is pressed against the side plates 19, and the two side plates 19 are rotatably provided with transverse rods 21, and the transverse rods 21 are rotatably provided with receiving blocks 22, the receiving blocks 22 are fitted between the two side plates 19, and the receiving blocks 22 are rotatably provided with hooks 23.

[0031] More specifically, since the receiving wheel 1 is connected to the external wire rope, the receiving wheel 1 is rotated by driving the movement of the wire rope, and the hook 23 can be driven to move with it under the action of the side plate 19, thereby completing the lifting and moving process of the object.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to quickly install the hexagonal sleeve 5 on the insertion tube 4, first slide the insertion tube 4 into the threaded sleeve 11 and the limiting ring 6. Due to the unidirectional setting of the multiple elastic sheets 7, it can be quickly pushed open, and the contact head 8 does not need to move along the rotation direction of the spiral groove 10, and can directly slide until the round head 14 is pressed against the side plate 19. Then, by rotating the hexagonal sleeve 5 for tightening, the compression spring 13 and the round head 14 are stably in contact with the side plate 19, thereby ensuring the rapid fixing process. Since the insertion rod 16 is in the insertion hole 15, the limiting plate 17 can be fixed, and the hexagonal groove 18 on the limiting plate 17 is stuck on the hexagonal section 12, so that the threaded sleeve 11 can be fixed, thereby ensuring the stability of the fixation. When it needs to be released, it only needs to be rotated along the spiral groove 10 to release the connection between the two.

[0033] Since the receiving wheel 1 is connected to the external wire rope, the receiving wheel 1 is driven to rotate by driving the movement of the wire rope, and the hook 23 can be driven to move accordingly under the action of the side plate 19, thereby completing the lifting and moving process of the object.

[0034] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
