DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-3 In an embodiment of the present invention, a material lifting equipment specially used for construction includes a base 1, a lifting bucket 2, a guide rail frame 3, a slider 4 and a winding mechanism 5; the lifting bucket 2 is fixedly connected with sliders 4 on both sides, and the sliders 4 are nested on the guide rail frame 3, so that the lifting bucket 2 can move up and down along the guide rail frame 3.

[0023] See also Figure 2 The winding mechanism 5 includes a main load-bearing rope 6 and a safety rope 12. A main winding wheel 7 is wound around the upper end of the main load-bearing rope 6. The main winding wheel 7 is fixedly connected to a winding shaft 8. The winding shaft 8 is rotatably connected to an anti-slip cover 9 through a bearing and extends to the outside of the anti-slip cover 9. The winding shaft 8 is connected to a winding motor 11 through a reducer 10. The winding motor 11 drives the winding shaft 8 to rotate through the reducer 10, thereby driving the main winding wheel 7 to wind the main load-bearing rope 6, thereby driving the lifting bucket 2 to move up and down.

[0024] The safety rope 12 is fixedly connected to the lifting bucket 2, and a safety winding wheel 17 is wound around the upper end of the safety rope 12, and the safety winding wheel 17 is sleeved and fixed with the winding shaft 8, and an elastic guide wheel 13 is arranged below the safety winding wheel 17, and the elastic guide wheel 13 abuts against the safety rope 12, and the elastic guide wheel 13 is rotatably connected with a movable plate 14, and the movable plate 14 is sleeved with a spring sleeve rod 16, and the spring sleeve rod 16 is fixedly connected with a fixed plate 15, and the fixed plate 15 is fixedly connected with the anti-slip cover 9; the elastic guide wheel 13 allows the safety rope 12 to be normally in the main load-bearing rope 6 It does not bear the weight of the lifting bucket 2 during operation. Specifically, when the main load-bearing rope 6 breaks, the safety rope 12 begins to be stressed, the spring guide wheel 13 moves under the force, and the spring on the spring sleeve rod 16 is compressed, so that the safety rope 12 straightens and begins to bear the weight of the lifting bucket 2. After the main load-bearing rope breaks, the lifting bucket 2 can still be lifted and lowered normally and continue to work to prevent the lifting bucket 2 from falling, so that the material transportation before the break is not affected. The main load-bearing rope can be replaced during construction breaks or construction stoppages to avoid affecting the construction period.

[0027] The dust collecting cylinder 18 is provided with fan blades 24, and the fan blades 24 are fixedly connected with a rotating shaft 25. A dustproof net 29 is nested and fixed at the end of the dust collecting cylinder 18.
