[0027] 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.

[0028] See also Figure 1-5 The utility model provides a technical solution, a wire rope lifting device for an electric hoist, comprising a frame 1, a drum 2, a wire rope 4 wound on the drum 2, and a double-wheel hook 5, wherein the drum 2 is provided with a rope reel 3 for guiding the winding and unwinding of the wire rope 4. Longitudinal beams 1.1 extending in the horizontal direction are respectively provided on both sides of the frame 1.

[0029] The fixing seat 6 comprises a pair of grooved members 6.1 which are clamped on both sides of the middle of the longitudinal beam 1.1 and connected by bolts, a support plate 6.2 fixed to the outer wall of the grooved member 6.1 near the front and rear ends, and a shaft 6.3 which is respectively mounted on the bottom of the support plate 6.2 at the front and rear ends.

[0030] The redirecting wheel assembly 7 comprises a set 7.1 rotatably mounted on the shaft 6.3 at the side away from the reel 2, a slot 7.2 fixed to the bottom surface of the set 7.1, and a pulley 7.3 rotatably mounted in the slot 7.2.

[0031] The rope end fixing member 8 comprises a second set 8.4 rotatably mounted on the front side of the middle of the shaft 6.3 on one side of the corresponding reel 2, a vertical plate 8.1 fixed to the bottom end of the second set 8.4, a fixing block 8.2 fixed to the side wall of the vertical plate 8.1, and a wedge block 8.3 vertically inserted in the middle of the fixing block 8.2. Among them, a slot 8.2.1 is vertically arranged in the middle of the fixing block 8.2 to be plugged and matched with the wedge block 8.3, and arc grooves 8.2.2 are respectively arranged in the middle of the front and rear walls of the slot 8.2.1, and a groove 8.3.1 is arranged in the middle of the outer peripheral wall of the wedge block 8.3.

[0032] The guide wheel assembly 9 includes a set 3 9.1 rotatably mounted on the rear side of the middle of the shaft 6.3 on one side of the corresponding reel 2, a columnar seat 9.2 fixed to the bottom end of the set 3 9.1, a rotating shaft 9.3 rotatably mounted on the middle of the columnar seat 9.2, a slot 2 9.4 fixed to the bottom end of the rotating shaft 9.3, and a pulley 2 9.5 rotatably mounted in the slot 2 9.4.

[0033] In summary, when in use, after the free end of the wire rope 4 passes through the rope reel 3, it first passes around the top of the pulley 2 9.5, then passes around the bottom of the groove wheel on one side of the double-wheel hook 5, the top of the pulley 1 7.3, and the bottom of the groove wheel on the other side of the double-wheel hook 5 in turn, and finally the rope end passes through the bottom end of the slot 8.2.1 and passes through the groove 8.3.1 on the wedge block 8.3 and then passes through the slot 8.2.1 downward again, the wedge block 8.3 is pressed into the slot 8.2.1, and the wire rope 4 passing through the slot 8.2.1 is stuck between the arc groove 8.2.2 and the groove 8.3.1, and the rope head on the lower side of the rope end fixing piece 8 is fixed with a rope clamp.

[0034] In this way, when lifting heavy objects, the wire rope 4 is wound and unwound on the drum 2 through the guiding action of the rope reel 3. During this period, the rotating shaft 9.3 rotates accordingly relative to the cylindrical seat 9.2, so that the lifting wire ropes 4 on both sides of the double-wheel hook 5 have the same inclination angle, so as to ensure that the double-wheel hook 5 is always lifted vertically in the middle position, thereby realizing the smooth lifting of the heavy object.
