[0002] Firefighting rigging ropes are mostly stored in rope reels during use to prevent knots or twists. During use, the ropes are used for descent. Trapped personnel are secured to the ropes at the top of the building and descend to safety. However, if the firefighting rigging ropes are not wound evenly during the winding process, they are prone to shaking during descent, which can easily cause injury to inexperienced users. Therefore, we propose a rigging rope winding device. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3A rigging rope winding device includes a first connecting rope 100 and a winding device 200. The winding device 200 includes a winding box 210. A first rotating rod 240 is rotatably connected to the left and right side walls of the winding box 210. A second connecting rope 250 is fixedly connected to the outer side of the first rotating rod 240. A second locking device 260 is fixedly connected to the upper side of the second connecting rope 250. A reciprocating screw 270 is rotatably connected to the upper side of the winding box 210. Two sets of spiral grooves are provided on the outer side of the reciprocating screw 270. The left and right sides of the two sets of spiral grooves of the reciprocating screw 270 are interconnected. A moving ring 280 is connected to the outer side of the reciprocating screw 270. The rear side of the moving ring 280 is open. A limiting groove matching the second connecting rope 250 is provided. A guide rod 290 is fixedly connected to the upper side of the winding box 210. The body of the guide rod 290 passes through the lower side of the moving ring 280. A first gear 271 is fixedly connected to the right side of the reciprocating screw 270. A second gear 241 is fixedly connected to the right side of the first rotating rod 240. The first gear 271 and the second gear 241 mesh. A handle is fixedly connected to the left side of the first rotating rod 240. The upper side of the first connecting rope 100 is fixedly connected to the winding device 200. A first lock 110 is fixedly connected to the lower side of the first connecting rope 100. During use, the winding device 200 is connected to the first connecting rope 100, the second gear 271, and the third gear 280. A locking device 110 is connected to the user's wearable safety belt. Then, a winding device 200 is suspended from the second locking device 260 via a second connecting rope 250. The operator controls the descent speed using the winding device 200, rotating a first rotating rod 240. This rotation drives the second connecting rope 250, thus completing the winding and releasing of the second connecting rope 250. The rotation of the first rotating rod 240 drives the second gear 241, which in turn drives the first gear 271, which in turn drives the reciprocating screw 270. The rotation of the reciprocating screw 270 drives the moving ring. The moving ring 280 moves left and right, which adjusts the position of the second connecting rope 250, allowing it to be evenly wound around the outside of the first rotating rod 240. The winding device 200 ensures the second connecting rope 250 is evenly wound around the outside of the first rotating rod 240, resulting in higher winding efficiency and tighter winding. This improves stability during subsequent use and makes the speed at which the second connecting rope 250 detaches from the first rotating rod 240 more uniform, thus enhancing stability during fire drills or actual use.

[0021] Two sets of springs 220 are fixedly connected to the upper side of the winding box 210. A friction block 230 is fixedly connected to the side of the springs 220 away from the winding box 210. A groove matching the springs 220 and friction block 230 is provided on the upper side of the winding box 210. During use, the elastic force generated by the springs 220 drives the friction block 230 closer to the second connecting rope 250. By setting the springs 220 and friction block 230 to keep the friction block 230 close to the second connecting rope 250, the second connecting rope 250 is kept taut, thus making the second connecting rope 250 more stable during winding. When the second connecting rope 250 disengages from the first rotating rod 240, it acts as a speed limiter to prevent injury from excessive disengagement speed, thereby improving the practicality of the device. Slider blocks are connected to both the upper and lower sides of the friction block 230. A groove matching the slider of the friction block 230 is provided on the upper side of the winding box 210. By setting the slider and groove, the friction block 230 is limited, indirectly improving the stability of the device.

[0022] A limiting ring 211 is fixedly connected to the front side of the inner wall of the winding box 210. The second connecting rope 250 is located between the moving ring 280 and the friction block 230. An arc-shaped groove is provided on the lower side of the limiting ring 211. By setting the limiting ring 211, the second connecting rope 250 is limited, preventing the second connecting rope 250 from squeezing the friction block 230 on only one side, thus improving the stability of the device. A protective box 212 is fixedly connected to the right side of the winding box 210. The first gear 271 and the second gear 241 are located inside the protective box 212. By setting the protective box 212, the first gear 271 and the second gear 241 are protected, thus improving the safety of the device.
