Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein and, therefore, the present invention is not limited to the specific embodiments disclosed in the following description.
Examples
Referring to the attached drawings of the specification, in the embodiment of the invention, a vector damping auxiliary structure applied to a descent control device comprises a shell 1, wherein a damping disc 4 is rotatably mounted at the center of the shell 1, a damping block 5 is arranged on the damping disc 4, a plurality of damping rods 6 are fixedly mounted on the shell 1, the centers of the damping rods 6 are uniformly distributed on the same circumference, and the damping rods 6 are arranged on the outer side of the damping disc 4;
the damping disc is characterized in that auxiliary damping devices are arranged on two sides of the damping disc 4 and comprise two rocking rods 11 rotatably mounted on the damping rods 6, a stretching device is arranged at the upper end of the shell 1, a pull rod 9 is fixedly connected to the lower end of the stretching device, a connecting rod 10 is hinged to the lower end of the pull rod 9, the other end of the connecting rod 10 is hinged to the upper end of the rocking rod 11, and a friction column 12 is mounted at the lower end of the rocking rod 11.
Further, stretching device includes spring housing 2, spring housing 2 fixed connection be in on the casing 1, the inside slide 7 that slides of spring housing 2, slide 7 center fixedly connected with hangs nose 3, hang nose 3 upwards extend outside spring housing 2, slide 7 with be connected with spring 8 between the inside upper wall of spring housing 2.
Furthermore, the friction column 12 is rotatably mounted on the rocker 11, which prevents the friction column 12 from locking the damping disk 4 when the slide 7 is moved upwards to the extreme position.
Furthermore, the number of the damping rods 6 is 5, and the two rocking rods 11 are distributed and installed on the two symmetrical damping rods 6.
The use process comprises the following steps:
when the descent control device is normally used, the damping disc 4 is connected with the planetary gear of the control rope, when a person descends on the descent control device, the damping disc 4 rotates, and the damping block 5 on the damping disc 4 is far away from the center of the damping disc 4 under the action of centrifugal force and collides with the damping rod 6 to reduce the rotating speed of the damping disc 4, so that the descent control effect is generated; when the load on the descent control device is overweight (greater than 100 KG), surpassed the normal compression range of spring 8, slide 7 moves the distance upwards relative to spring housing 2 and surpasss normal scope, the lower extreme of two rockers 11 moves to the centre under the effect of pull rod 9, connecting rod 10, make friction post 12 and damping piece 5 collide each other and provide extra resistance, the rotational speed of damping dish 4 has been reduced once more, with original damping piece 5, the resistance between the damping rod 6 further reduces personnel's descending speed together, avoid weight overweight, the falling speed is too fast and lead to the user personnel to appear dangerous condition.
In the process, through the arrangement of the auxiliary damping device, when the user is overweight, additional resistance is generated to further limit the descending speed, so that the user is protected, the condition that the descending speed is too high due to overweight is avoided, and the use safety of the descent control device is improved; this application simple structure, the practicality is strong, and easy operation is worth promoting.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several variations and modifications without departing from the concept of the present invention, and these should be considered as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
