[0023] 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.

[0024] See also Figure 1-5 The utility model provides a technical solution: a hook assembly of a European single-beam electric hoist, comprising a traveling frame 1, a winding assembly 2, a wire rope 3 and a hook 4.

[0025] The hook 4 comprises a transverse axis 4.1, a sheave 4.2 rotatably mounted on both ends of the transverse axis 4.1, a wheel cover 4.4 covering the outside of the sheave 4.2, and a hook head 4.3 connected to the middle of the transverse axis 4.1, and a locking member 5 is provided on the hook head 4.3. The hook head 4.3 comprises a sleeve 4.3.1 mounted on the middle of the transverse axis 4.1, a column 4.3.2 with a top fixed to the bottom of the sleeve 4.3.1, and an arc-shaped hook 4.3.3 with a top fixed to the bottom of the column 4.3.2, a notch 4.3.3.1 is provided on the outer side of the arc-shaped hook 4.3.3 near the open end, a clamping groove 4.3.3.2 is provided on the inner peripheral wall of the arc-shaped hook 4.3.3 near the top, and a sliding groove 4.3.3.3 is provided on the outer peripheral wall of the arc-shaped hook 4.3.3 corresponding to the middle of the clamping groove 4.3.3.2.

[0026] The locking member 5 comprises a bottom ring 5.1 which is respectively engaged with the notch 4.3.3.1 and the slot 4.3.3.2, a vertical rod 5.2 whose bottom end is vertically fixed to the outer peripheral wall of the bottom ring 5.1, a round plate 5.5 fixed to the top of the vertical rod 5.2, and a spring 1 5.3 which is sleeved on the outside of the vertical rod 5.2. The bottom end of the spring 1 5.3 is fixedly connected with a sleeve ring 5.4 which is slidably sleeved with the vertical rod 5.2.

[0027] In summary, when performing the hook operation, first pull the bottom ring 5.1 into the slot 4.3.3.2 through the vertical rod 5.2, so that the locking member 5 as a whole does not occupy the internal space of the arc hook 4.3.3, so as to facilitate the arc hook to be quickly hung on the lifting ring or binding belt of the heavy object. Then push the bottom ring 5.1 out of the slot 4.3.3.2 through the vertical rod 5.2, and rotate the bottom ring 5.1 through the vertical rod 5.2 to put the bottom ring 5.1 in the notch 4.3.3.1 at the open end of the arc hook 4.3.3. At this time, the spring 1 5.3 is in a compressed state, that is, the collar 5.4 is pressed against the outside of the slide slot 4.3.3.3, so that the bottom ring 5.1 is firmly stuck in the notch 4.3.3.1 to prevent it from being unhooked.

[0028] When removing the hook, first push the vertical rod 5.2 through the circular plate 5.5 to compress the spring 1 5.3, so as to disengage the bottom ring 5.1 from the open end of the arc hook 4.3.3, and then rotate the bottom ring 5.1 and pull it back into the slot 4.3.3.2, so that the operation of quick hook removal can be achieved, which is more convenient and greatly improves the efficiency of hook removal.

[0029] In order to facilitate the positioning and placement of the locking member 5 after the hook is removed, an ear plate 4.3.4 is fixed to the middle of one side of the shaft sleeve 4.3.1 corresponding to the vertical rod 5.2, a positioning rod 4.3.5 is vertically fixed to the front wall of the ear plate 4.3.4, a spring 2 5.8 is fixedly connected to the outer edge of the top surface of the circular plate 5.5, and a C-shaped ring 5.9 is fixedly connected to the top of the spring 2 5.8. That is, the C-shaped ring 5.9 is pulled to make the spring 2 5.8 in a tensioned state, so that the C-shaped ring 5.9 is hooked on the positioning rod 4.3.5 to achieve the storage of the locking member 5 after the hook is removed.

[0030] A square column 5.6 is fixed at the center of the top surface of the circular plate 5.5, a square sleeve 5.7 is slidably sleeved on the top of the square column 5.6, and the top of the square sleeve 5.7 is fixedly connected to the bottom end of the C-shaped ring 5.9. That is, when the spring 2 5.8 is pulled by the C-shaped ring 5.9, the square column 5.6 sleeves relative to the square sleeve 5.7 to achieve linear stretching of the spring 2 5.8.

[0031] In order to facilitate pulling the C-shaped ring 5.9 and to facilitate pushing the bottom ring 5.1 through the vertical rod 5.2, a top rod 5.10 is vertically fixed to the top of the C-shaped ring 5.9, and a top plate 5.11 is fixed to the top of the top rod 5.10.
