Embodiments of the present utility model are described below with reference to fig. 1 to 4. It should be understood that the following description is only illustrative of embodiments of the utility model and is not intended to limit the utility model in any way.

In order to reduce the descending speed of the rope reel when being thrown down from a high place, avoid the failure of escape slow descending equipment caused by the damage of the rope reel, and avoid the danger of people or articles smashing to the ground from the rope reel descending at a high speed, the utility model provides the rope reel slow descending device and the escape slow descending equipment. The rope reel descent control device provided by the utility model is first described below.

As shown in fig. 1, a rope reel descent control device 100 according to an embodiment of the present utility model includes a rope winding assembly 10 and a speed reducing assembly 20. Wherein the roping assembly 10 is used for winding a rope 30; the deceleration assembly 20 comprises at least two guide posts 21, and the guide posts 21 are arranged at intervals. The deceleration assembly 20 can decelerate the descending rope 30 during the descent of the rope reel descent control device 100 from a high place.

Specifically, roping assembly 10 is rotatably coupled to deceleration assembly 20 such that rotation of roping assembly 10 winds rope 30 around a circumferential sidewall of roping assembly 10 or unwinds rope 30 wound around roping assembly 10. As shown in fig. 1-3, the deceleration assembly 20 may be provided with a plurality of guide posts 21, for example, 2, 3, 4 guide posts 21 may be provided, with a spacing between adjacent guide posts 21 that is greater than the diameter of the rope 30. The rope 30 may be wound through a gap between at least two guide posts 21 and then wound around a circumferential sidewall of the rope winding assembly 10. For example, as shown in fig. 2, the rope 30 is wound around the two guide posts 21 in an "S" shape and passes through a gap between the two guide posts 21, and the surface of the rope 30 contacts the side surfaces of the two guide posts 21.

When the rope reel descent control device 100 is thrown from a high place, the rope reel assembly 10 can rotate to put down the rope 30, and the outer surface of the rope 30 rubs with the outer surface of the guide post 21 in the moving process, so that the descending speed of the rope 30 is slowed down, namely the descending speed of the rope reel descent control device 100 is slowed down, the escape descent control device is prevented from being disabled due to the fact that the rope 30 is wound and clamped due to the too fast descending speed, and the danger caused by personnel or objects on the ground when the rope reel descent control device 100 is thrown from the high place can be greatly reduced due to the fact that the descending speed of the rope reel descent control device 100 is slowed down.

As shown in fig. 3, in some embodiments, the roping assembly 10 can include a connecting shaft 11 and a disk surface 12. Wherein one end of the rope 30 is fixed to the surface of the connection shaft 11, and the rope 30 is adapted to be wound along the circumferential side wall of the connection shaft 30. The number of the disc surfaces 12 is two, the two disc surfaces 12, and the disc surfaces 12 are fixedly connected to two axial side surfaces of the connecting shaft 11. When the rope 30 descends, the connecting shaft 11 and the disk surfaces 11 on both sides thereof can rotate synchronously. The two disc surfaces 12 can function as a blocking rope 30, and can prevent the rope 30 wound on the connecting shaft 11 from falling off.

As shown in fig. 1, in some embodiments, the deceleration assembly 20 may also include a rope reel bracket 22. One end of the rope reel support 22 is rotatably connected with the connecting shaft 11, one end of the rope reel support 22, which is far away from the rope winding assembly 10, is provided with a guide post 21, and the guide post 21 is parallel to the axis of the connecting shaft 11. Thus, when the rope 30 descends, the end of the rope reel bracket 22 where the guide post 21 is installed is maintained vertically upward, and the connection shaft 11 can be rotated at the lower end of the rope reel bracket 22.

The side of the disc 12 facing away from the connecting shaft 11 contacts with the side of the rope reel support 22 facing the connecting shaft 11, so that friction occurs between the disc 12 and the rope reel support 22 during the descending of the rope 30, thereby slowing down the rotation speed of the rope reel 12, and slowing down the rotation speed of the connecting shaft 11, thereby slowing down the descending speed of the rope 30. Further, the rope 30 is usually a steel wire rope with a certain rigidity, and the friction force between the disc surface 12 and the rope reel support 22 can prevent the steel wire rope wound around the rope winding assembly 10 from being loosened and unfolded due to the rigidity.

As shown in fig. 3, in some embodiments, the rope reel bracket 22 includes a left bracket 221 and a right bracket 222. The left bracket 221 and the right bracket 222 have the same structure, are symmetrically arranged at two sides of the rope winding assembly 10, and two ends of the guide post 21 are respectively connected with the left bracket 221 and the right bracket 222.

Specifically, the left bracket 221 and the right bracket 222 are respectively disposed at one side of the disk surface 12 at two ends of the connecting shaft 11 facing away from the connecting shaft 11. The left bracket 221 is provided with a first rotating shaft portion 2211, the right bracket 222 is provided with a second rotating shaft portion 2221, the first rotating shaft portion 2211 penetrates through the disc surface 12 on one side of the connecting shaft 11, the second rotating shaft portion 2221 penetrates through the disc surface 12 on the other side of the connecting shaft 11 to be connected with the first rotating shaft portion 2211, and the connecting shaft 11 is sleeved on the first rotating shaft portion 2211 and the second rotating shaft portion 2221.

In some embodiments, the disc 12 may be circular, the first rotating shaft portion 2211 and the second rotating shaft portion 2221 are cylindrical, the center of the disc 12 is provided with a circular hole adapted to the first rotating shaft portion 2211 and the second rotating shaft portion 2221, the first rotating shaft portion 2211 and the second rotating shaft portion 2221 may be connected by a fastener 23 to form a rotating shaft, and the connecting shaft 11 is sleeved on the rotating shaft. The fastener 23 may be a socket head cap screw.

In some embodiments, the guide post 21 may be rotatably connected to the rope reel 22, and the guide post 21 may rotationally rub against the surface of the rope 30 when the rope 30 descends, so that abrasion of the rope 30 may be reduced.

As shown in fig. 1, in some embodiments, a rope hole 24 is formed in an end of the deceleration assembly 20 facing away from the rope winding assembly 10, and a rope 30 is passed through the rope hole 24. To prevent rope hole 24 from wearing rope 30, in some embodiments, rope reel descent device 100 may include a wear sleeve (not shown) that may be embedded within rope hole 24 through which rope 30 may pass. The wear sleeve may be copper to avoid wearing the rope 30 during lowering.

On the other hand, the embodiment of the utility model also provides escape descent control equipment. As shown in fig. 4, the escape descent control device includes a descent control device 200, a rope 30, and the rope reel descent control device 100 according to any one of the above embodiments.

Specifically, one end of the rope 30 may be fixed on a high-rise building, for example, a hanging point may be installed on a wall surface of the high-rise building, and one end of the rope 30 is fixedly connected with the hanging point. The other end of the rope 30 is connected to the rope reel descent control device 100, and the descent control device 200 is provided on the rope 30. When the high-rise building is in danger of fire and the like, the evacuee 300 can throw the rope-disc descent control device 100 from a high place, the rope-disc descent control device 100 can slowly descend the rope 30, the rope 30 is kept vertical, then the evacuee 300 wearing the safety belt can hang the hook of the safety belt on the descent control device 200, and the descent control device 200 can drive the evacuee 300 to slowly descend to the ground along the rope, so that the escape is realized.
