DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example: Figure 1-4 As shown, the utility model provides a technical solution: a controllable safety rope, including a connecting box 1, a rotating shaft 12 is rotatably connected at the center between the inner walls of the connecting box 1, a safety rope body 13 is wrapped around the outer ring of the rotating shaft 12, a side plate 34 is fixedly connected to the side end of the connecting box 1 near the center, an alarm 35 is fixedly connected to the center of the bottom end of the side plate 34, an installation box 16 is fixedly connected to the center of the top end of the connecting box 1, a slider 17 is slidably inserted at the bottom end of the installation box 16, a contact wheel 19 is fixedly connected to the bottom end of the slider 17, and the contact wheel 19 is in contact with the safety rope body 13.
[0020] A spring 18 is symmetrically fixedly connected to the top of the installation box 16 near the center, and the bottom end of the spring 18 is fixedly connected to the slider 17.
[0021] By adopting the above technical solution, two springs 18 are arranged at the top of the installation box 16 to facilitate the lifting and resetting of the slider 17.
[0022] A limit shaft 14 is rotatably connected between the inner walls of the connection box 1 and close to the rotating shaft 12 . An auxiliary wheel 15 is slidably connected to the outer ring of the limit shaft 14 , and the safety rope body 13 is in contact with the auxiliary wheel 15 .
[0023] By adopting the above technical solution, an auxiliary wheel 15 is provided on the outer ring of the limiting shaft 14 to facilitate winding and releasing the safety rope body 13, so as to prevent the safety rope body 13 and the connection box 1 from being worn.
[0024] A motor 11 is fixedly mounted at the front center of the connection box 1 , and an output end of the motor 11 passes through the connection box 1 and is fixedly connected to a rotating shaft 12 .
[0025] By adopting the above technical solution, the motor 11 is operated so that the fixedly connected rotating shaft 12 is rotated.
[0026] A long plate 3 is fixedly connected to the bottom end of the slider 17 near the center of one side, and a short plate 32 is fixedly connected to the side wall of the box 1 near the center.
[0027] By adopting the above technical solution, a long plate 3 is provided at the bottom end of the slider 17 and a short plate 32 is provided on the side wall of the connection box 1 in order to facilitate automatic activation of the alarm 35 .
[0028] A rolling ball 31 is provided on one side of the bottom end of the long board 3 close to the short board 32 , and a control button 33 is fixedly connected to one side of the top end of the short board 32 close to the long board 3 , and the control button 33 and the rolling ball 31 are at the same level.
[0029] By adopting the above technical solution, when the long board 3 descends to a certain extent, the rolling ball 31 will touch the control button 33, thereby realizing the work of turning on the alarm 35.
[0030] Working principle: When the device is in use, first install the short plate 32 in an appropriate position, so that when there is less rope left in the safety rope body 13, the ball 31 can touch the control button 33. When the length of the safety rope body 13 needs to be adjusted during operation, the running motor 11 can be controlled to rotate the fixedly connected rotating shaft 12, thereby rotating the safety rope body 13 on the outer ring of the rotating shaft 12. Then, under the cooperation of the limit shaft 14 and the auxiliary wheel 15, the safety rope body 13 is released, thereby completing the adjustment of the length of the safety rope body 13. The auxiliary wheel 15 is provided to prevent the wear of the safety rope body 13 and the connection box 1, thereby solving the problem that the length of the safety rope cannot be adjusted during operation.
[0031] At the same time, the friction wheel 19 at the bottom end of the slider 17 contacts the safety rope body 13. When the safety rope body 13 releases a certain length, the safety rope body 13 wrapped around the outer ring of the rotating shaft 12 will become less. Then, under the action of the two springs 18, the slider 17 drives the friction wheel 19 to descend, so that the fixedly connected long board 3 drives the rolling ball 31 to descend. After the rolling ball 31 descends to a certain extent, it will touch the control button 33 above the short board 32, so that the alarm 35 will work, thereby realizing the effect of reminding the staff of the remaining length of the safety rope body 13, thereby solving the problem that the hook assembly of the safety rope is not provided with an auxiliary structure, so that the user cannot know the remaining length of the safety rope in time.
[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
