[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the escape rope requires certain usage experience during use, and inexperienced users are prone to falling too fast when using it, which leads to the probability of falling and injury. Utility Model Content
[0004] In order to solve the above problems, the utility model provides an escape rope descending device.
[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: an escape rope descent device, comprising a support plate, a rotating seat is symmetrically installed on the side wall of the support plate, and a rotating groove is opened on the side walls of the two rotating seats close to each other, and rolling rollers are arranged to rotate together in the two rotating grooves, a sliding rope is wound on the side wall of the rolling roller, and a safety lock is installed on the end of the sliding rope away from the rolling roller, and a locking device for locking the rolling roller is installed on the rolling roller; a fixed groove is opened in a circumferential array on the side wall of the rolling roller, and a plurality of blocking grooves opposite to the fixed groove are opened in a circumferential array on the inner wall of the rotating groove, and a sliding groove is opened on the inner walls of the plurality of fixed grooves.

[0006] By adopting the above technical solution, when the staff needs to use the zipline, the staff needs to fix the zipline at the waist position through the safety lock. At this time, the staff can use the zipline to descend, and during this process, the rolling roller rotates. At this time, if the descent speed is too fast, the staff needs to start the locking device to lock the rolling roller, thereby reducing the probability of the user falling due to the too fast descent speed.

During this process, the limit block limits the sliding rod, thereby reducing the probability of the sliding rod following the rotation of the threaded rod, thereby improving the stability of the device.
[0013] Furthermore, one end of the fixing block away from the sliding rod is chamfered.
[0014] By adopting the above technical solution, the chamfer reduces the probability of the fixed block sliding into the limiting groove, thereby reducing the working difficulty of the staff.

[0018] 1. In this application, when the staff needs to use the zipline, the staff needs to fix the zipline at the waist position with a safety lock. At this time, the staff can use the zipline to descend, and during this process, the rolling roller rotates. At this time, if the descent speed is too fast, the staff needs to start the locking device to lock the rolling roller, thereby reducing the probability of the user falling due to the too fast descent speed;

In the present application, when the staff needs to lock the rolling roller, the staff needs to start the motor, thereby rotating the output shaft of the motor, so that the slide bar slides toward the fixed block under the action of the motor output shaft, and the slide bar gradually approaches and finally presses against the first inclined surface, so that the fixed block slides into the blocking groove at one end under the action of the slide bar, and the fixed block fixes the rolling roller, thereby reducing the probability of the user falling due to excessive descent speed;
[0020] 3. In the present application, when the slide bar and the fixed block are separated from each other, the reset block slides toward the fixed groove under the action of the reset spring, and then the fixed block slides toward the fixed groove under the action of the reset block, so that the fixed block and the limit groove are separated from each other. At this time, the rolling roller continues to rotate, thereby reducing the difficulty of the staff to reset the fixed block, thereby reducing the difficulty of the staff's work.

The zip line 13 is wound around the side wall of the rolling roller 12, and the safety lock 14 is installed at the end of the zip line 13 away from the rolling roller 12.
[0028] When the staff needs to use the zip line 13, the staff needs to fix the zip line 13 at the waist position through the safety lock 14. At this time, the staff can use the zip line 13 to descend, and during this process, the rolling roller 12 rotates. At this time, if the descent speed is too fast, the staff needs to start the locking device 3 to lock the rolling roller 12, thereby reducing the probability of the user falling due to the too fast descent speed.
[0029] A fixed groove 21 is provided in a circumferential array on the side wall of the rolling roller 12, and a plurality of blocking grooves 22 facing the fixed grooves 21 are provided in a circumferential array on the inner wall of the rotating groove 2. A sliding groove 23 is provided on the inner walls of the plurality of fixed grooves 21. The locking device 3 is installed on the rolling roller 12 and is used to lock the rolling roller 12. The locking device 3 includes a slide bar 31 and a fixed block 32. The slide bar 31 is a round rod-shaped structure, and its axis coincides with the axis of the rolling roller 12. The slide bar 31 is slidably arranged in the sliding groove 23. The fixed block 32 is a rectangular block structure. A plurality of fixed blocks 32 are provided and are slidably arranged in the plurality of fixed grooves 21, respectively. The fixed block 32 is slidably connected to the blocking groove 22, and a first inclined surface 33 is provided on the edge where the side wall of the fixed block 32 away from the blocking groove 22 and the side wall thereof close to the slide bar 31 intersect.
[0030] The inner wall of the slide groove 23 is provided with a receiving groove 24, and the motor 4 is installed in the receiving groove 24, and the axis of its output shaft coincides with the axis of the slide rod 31. The threaded rod 41 is fixedly arranged at the end of the output shaft of the motor 4, and its axis coincides with the axis of the output shaft of the motor 4, and the threaded rod 41 is threadedly connected with the slide rod 31.
[0031] When the staff needs to lock the rolling roller 12, the staff needs to start the motor 4, thereby rotating the output shaft of the motor 4, so that the slide bar 31 slides towards the fixed block 32 under the action of the output shaft of the motor 4, and then the slide bar 31 gradually approaches and finally presses against the first inclined surface 33, so that the fixed block 32 slides into the blocking groove 22 at one end under the action of the slide bar 31, and then the fixed block 32 fixes the rolling roller 12, thereby reducing the probability of the user falling due to excessive descent speed.
[0032] A reset groove 25 is provided on the inner wall of the fixed groove 21. The reset block 5 is a rectangular block structure.

[0036] In order to reduce the difficulty of the work of the staff, a chamfer 7 is provided at one end of the fixing block 32 away from the slide rod 31. The chamfer 7 reduces the probability of the fixing block 32 sliding into the limiting groove 26, thereby reducing the difficulty of the work of the staff.
[0037] In order to reduce the difficulty of the staff's work, a remote controller 8 is mounted on the safety lock 14, and the remote controller 8 is electrically connected to the motor 4.
