[0023] The utility model provides a hoisting mechanism for a multi-hoisting point winch through improvement. The technical solution of the utility model is:

[0024] like Figures 1 - 3 As shown, a lifting mechanism for a multi-lifting point winch includes a base 1, a winch 2 is fixed to the base 1 by bolts, a steel rope 6 is provided on the winch 2, one end of the steel rope 6 is fixed to the winch 2, and the steel rope 6 is wound around the winch 2. A lifting assembly 4 is provided on the base 1, and the lifting assembly 4 includes a support rod 41, a cross rod 42, a threaded block 45, a sliding shell 48, a second screw 49 and a threaded sleeve 410. Two support rods 41 are fixedly connected to the base 1, two cross rods 42 are respectively fixedly connected to the two support rods 41, the threaded block 45 is slidably connected in the cross rod 42, the sliding shell 48 is fixedly connected to the threaded block 45, the sliding shell 48 is slidably connected to the two cross rods 42, the second screw 49 is rotatably connected in the sliding shell 48, and the threaded sleeve 410 is threadedly connected to the second screw 49. A connecting assembly 5 is provided on the base 1.

[0025] Further, such as Figures 1 - 3 As shown, the lifting assembly 4 also includes a first motor 43 and a first screw 44. The first motor 43 is fixed to the cross bar 42 by bolts, and the first screw 44 is fixed to the output shaft of the first motor 43 by bolts. The first screw 44 is rotatably connected to the cross bar 42. The length of the first screw 44 is equal to the inner wall length of the cross bar 42. The threaded block 45 is threadedly connected to the first screw 44.

[0026] Further, such as Figures 1 - 3As shown, the hoisting assembly 4 further includes a through hole 46, a second motor 47, and a limiting plate 411. The through hole 46 is formed in the cross bar 42. A slider is slidably connected in the through hole 46. The second motor 47 is fixed to the slider by bolts. The output shaft of the second motor 47 is fixed to the second screw rod 49 by bolts. Two limiting plates 411 are fixedly connected to the threaded sleeve 410. The two limiting plates 411 are symmetrical about the threaded sleeve 410. The two limiting plates 411 are slidably connected in the sliding shell 48.

[0027] Furthermore, as Figures 1 - 3 shown, the connecting assembly 5 includes a fixed column 51 and a connecting plate 52. The fixed column 51 is fixedly connected to the steel rope 6. The bottom of the fixed column 51 is located at the central position of the top of the connecting plate 52. The connecting plate 52 is fixedly connected to the fixed column 51.

[0028] Furthermore, as Figures 1 - 3 shown, the connecting assembly 5 further includes a fixing plate 53, a rotating rod 54, and a hook 55. A plurality of fixing plates 53 are fixedly connected to the fixed column 51 and the connecting plate 52. The fixing plates 53 are distributed in a circular array on the fixed column 51 and the connecting plate 52. The two ends of a plurality of rotating rods 54 are respectively rotatably connected to a plurality of fixing plates 53. A triangle is formed among the fixed column 51, the connecting plate 52, and the rotating rod 54, making its structure more stable. A plurality of hooks 55 are fixedly connected to the connecting plate 52. The plurality of hooks 55 are distributed in a circular array at the bottom of the connecting plate 52.

[0029] Furthermore, as Figures 1 - 3 shown, the base 1 is provided with a counterweight 3 and universal wheels 7. The counterweight 3 is fixed to the base 1 by bolts to ensure that the weight of the counterweight 3 is greater than the weight of the goods. Four universal wheels 7 are provided at the bottom of the base 1. All four universal wheels 7 are provided with latches for easy fixing.

[0030] The specific working method is as follows: Push the device to the working position through the universal wheels 7, then fix the universal wheels 7, start the winch 2, so that the steel cable 6 unfolds. The connecting assembly 5 pulls the steel cable 6 downwards due to its own weight, and uses the hook 55 on the connecting assembly 5 to lift the goods. Since multiple hooks 55 are provided, different numbers of hooks 55 can be selected according to the different goods to ensure that the goods will not tilt and fall during the lifting process. After the goods are fixed, start the winch 2, so that the steel cable 6 contracts, pulling the connecting assembly 5 upwards. After the goods are lifted to a suitable height, start the first motor 43, and its output shaft drives the first screw rod 44 to rotate, so that the threaded block 45 starts to move, and the sliding shell 48 moves accordingly, driving the second screw rod 49 and the threaded sleeve 410 to move. Since the steel cable 6 is arranged on the threaded sleeve 410 and the connecting assembly 5 is arranged at the tail of the steel cable 6, the goods move along with the sliding shell 48, thus achieving the effect of adjusting the longitudinal position of the goods. Then start the second motor 47, and its output shaft drives the second screw rod 49 to rotate. Since the threaded sleeve 410 is threadedly connected to the second screw rod 49, the threaded sleeve 410 starts to move, driving the steel cable 6 and the connecting assembly 5 to move, so that the goods also move accordingly, thus achieving the effect of adjusting the lateral position of the goods.
