[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a fall-proof winch for construction engineering, including a support 1. A winding module 2 is fixedly connected above the support 1. An adjustment module 4 is fixedly connected in front of the winding module 2, and a fixed module 3 is fixedly connected behind the adjustment module 4. When the equipment is running, the winding module 2 winds up the wire rope, and then the adjustment module 4 drives the wire rope to move back and forth to prevent it from overlapping on the winding module 2. When the equipment stops running, the fixed module 3 locks the adjustment module 4 to prevent the wire rope from falling.

[0024] like Figure 2 As shown, this utility model provides a technical solution: the winding module 2 includes a motor 21, a fixed shaft 28, and a fixed shaft 27. The motor 21 is fixedly connected to the bracket 1. Fixed seats 24 are rotatably connected to both ends of the fixed shaft 28. Fixed seats 25 are rotatably connected to both ends of the fixed shaft 27. Both fixed seats 25 and fixed seats 24 are fixedly connected to the bracket 1. The fixed shaft 27 is located above the fixed shaft 28. The motor 21 is fixedly connected to the bracket 1 below the fixed shaft 28. A sprocket is fixedly connected to the output shaft of the motor 21. A sprocket 23 and a sprocket 22 are fixedly connected between the two fixed seats 24 on the fixed shaft 28. The sprocket 23 is located below the sprocket 22. On the left side, a fixed shaft 27 is fixedly connected between two fixed seats 25 to a drum 29 and a sprocket 26. The sprocket 26 is located to the left of the drum 29. The sprocket on the output shaft of the motor 21 drives the sprocket 23 through a chain, and the sprocket 22 drives the sprocket 26 through a chain. When the wire rope needs to be wound up, the motor 21 starts to drive the sprocket 23 to rotate through the chain. Then, the fixed shaft 28 drives the sprocket 22 to rotate through the fixed shaft 28. The sprocket 22 then drives the sprocket 26 through the chain. Finally, the sprocket 26 drives the drum 29 to rotate through the fixed shaft 27. Fixed seats 25 and 24 prevent the fixed shaft 27 and the fixed shaft 28 from shifting during rotation.

[0025] like Figure 3As shown, this utility model provides a technical solution: the adjustment module 4 includes a base 42, which is fixedly connected to the bracket 1. A second motor 41 is fixedly connected to the top of the base 42. A lead screw 44 is fixedly connected to the output shaft of the second motor 41. Fixed seats 43 and 48 are rotatably connected to the left and right ends of the lead screw 44, respectively. Both fixed seats 48 and 43 are fixedly connected to the base 42. A sliding nut 45 is threaded onto the outer surface of the lead screw 44. A slider 47 is fixedly connected to the front of the sliding nut 45. A slider 47 slides below the slider 47. The system is connected to a slide rail 46. Support rod 412 and support rod 49 are fixedly connected to the left and right sides of the slide rail 46, respectively. Both support rod 412 and support rod 49 are fixedly connected to the bracket 1. A slide rail 410 is fixedly connected between support rod 49 and support rod 412. The slide rail 410 is located above the slide rail 46. A slider 411 is slidably connected below the slide rail 410. When the wire rope is wound up, the motor 41 will drive the lead screw 44 to rotate. Then, the lead screw 44 will drive the slider 47 to move left and right through the sliding nut 45.

[0026] like Figure 4 As shown, this utility model provides a technical solution: a support rod 413 and a support rod 417 are fixedly connected between slider 2 411 and slider 1 47. The support rod 417 is located to the left of the support rod 3 413. A spring 414 is fixedly connected inside both the support rod 417 and the support rod 3 413. A slider 415 is fixedly connected above each of the two springs 414. Both the support rod 417 and the support rod 3 413 are slidably connected to the slider 415 inside them. Roller 416 is rotatably connected to the middle of the support rod 417. Roller 418 is rotatably connected below roller 416. The other end of roller 418 is rotatably connected to support rod 413. When slider 47 moves, it will drive slider 411, roller 418 and roller 416 to move together through support rod 417 and support rod 413. Spring 414 contracts and pulls roller 416 down through slider 415, so that roller 416 and roller 418 clamp the wire rope.

[0027] like Figure 5As shown, this utility model provides a technical solution: a dust cover 31 is fixedly connected to the rear of the support rod 417, a spring 32 is fixedly connected inside the dust cover 31, a slider 33 is fixedly connected below the spring 32, a cylinder 34, the power source of the slider 33, is fixedly connected below the slider 33, the cylinder 34 is fixedly connected to the dust cover 31, and limit blocks 35 are fixedly connected to both the front and rear sides of the dust cover 31. A baffle 36 is fixedly connected to the left side of the dust cover 31. When the equipment is running, the cylinder 34 starts to pull the slider 33 down. When the equipment stops, the cylinder 34 stops venting, the spring 32 contracts to pull the slider 33 up, and the limit blocks 35 prevent the slider 33 from falling out of the dust cover 31.

[0028] like Figure 6 As shown, this utility model provides a technical solution: Gear 37 is fixedly connected to the left side of both roller 416 and roller 418. A slide rail 39 is provided on the right side of the dust cover 31. Gear 38 is slidably connected inside the slide rail 39. A slide rail 410 is provided on the right side of slider 43. The left end of gear 238 is slidably connected to slide rail 410. When gear 238 runs to the uppermost end of slide rail 39, both gears 37 mesh with gear 238. When slider 43 descends, slider 43 drives gear 238 to descend along slide rail 39 through slide rail 410, moving it away from gear 137. When slider 43 rises, it makes gear 238 mesh with both gears 137 through slide rail 39, preventing it from continuing to rotate.

[0029] The working principle of the winch used in this fall-proof building project will be explained in detail below.

[0030] like Figure 1-6As shown, when the wire rope needs to be wound, motor 21 drives sprocket 23 to rotate via chain. Then, fixed shaft 28 drives sprocket 22 to rotate via fixed shaft 28. Sprocket 22 then drives sprocket 3 26 via chain. Sprocket 3 26 then drives drum 29 to rotate via fixed shaft 27. Fixed seats 25 and 24 prevent fixed shafts 27 and 28 from shifting during rotation. When the wire rope is wound, motor 41 drives screw 44 to rotate. Sprocket 44 then drives slider 47 to move left and right via sliding nut 45. When slider 47 moves, it drives slider 411, roller 418, and roller 416 via support rod 417 and support rod 3. When the equipment starts moving, spring 414 contracts and pulls roller 416 down via slider 415, causing roller 416 and roller 418 to clamp the wire rope, making the wire rope move left and right. When the equipment is running, cylinder 34 starts and pulls slider 33 down. Slider 33 drives gear 38 down along slide rail 39 via slide rail 310, moving it away from gear 37. When the equipment stops, cylinder 34 stops venting, spring 32 contracts and pulls slider 33 up. Limit block 35 prevents slider 33 from falling out of dust cover 31. When slider 33 rises, it causes gear 38 to mesh with two gears 37 via slide rail 39, preventing it from continuing to rotate.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
