[0026] The specific implementation of the utility model will be described in detail below, but it should be understood that the protection scope of the utility model is not limited by the specific implementation.

[0027] As Figures 1-5 shown, the pull cable slow release control device provided by the utility model embodiment comprises a speed control mechanism 2, and the speed control mechanism 2 adjusts the speed of the movement of the cable body 1 by adjusting the friction between the cable body 1 and the speed control mechanism 2. The speed control mechanism 2 is arranged at the cable body 1, can adjust the friction between the cable body 1 and the speed control mechanism 2, thereby adjusting the speed of the movement of the cable body 1, and achieves the purpose of controlling the speed of the cable.

[0028] Referring to Figure 1 , the speed control mechanism 2 comprises clamping wheels 201, sliding blocks 202, adjusting plates 203, threaded rods 204, handles 205 and supports, the clamping wheels 201 are provided in two, and the two clamping wheels 201 are respectively located at the two sides of the cable body 1, the clamping wheels 201 are inserted into the sliding blocks 202, the supports are provided with sliding grooves, the sliding blocks 202 are matched with the sliding grooves, the sliding blocks 202 are connected with the adjusting plates 203, the adjusting plates 203 are connected with the threaded rods 204 through threads, the threaded rods 204 are rotationally connected with the supports, the handles 205 are arranged at one end of the threaded rods 204, and the handles 205 are provided with anti-skid lines for increasing the friction. The clamping wheels 201 can be fixedly connected with the sliding blocks 202, that is, when the cable body 1 moves, the clamping wheels 201 will not rotate with the movement of the cable body 1.​

[0029] Rotating the threaded rod 204 can drive the adjusting plate 203 to move. The adjusting plate 203 is connected to the slider 202, and the clamping wheel 201 is inserted into the slider 202. The movement of the adjusting plate 203 can drive the clamping wheel 201 to move together, thereby adjusting the position of the clamping wheel 201. When the two clamping wheels 201 approach each other, they will squeeze the cable body 1, which will increase the friction between the cable body 1 and the clamping wheel 201, thereby achieving the purpose of controlling the moving speed of the cable body 1.

[0030] The speed control mechanism 2 adjusts the speed of the cable body 1 by adjusting the friction between it and the cable body 1. Therefore, the cable body 1 will wear against the speed control mechanism 2 during the movement. In order to detect whether the outer surface of the cable body 1 has been significantly worn due to the speed control mechanism 2, a detection mechanism is provided on the outside of the speed control mechanism 2.

[0031] The detection mechanism is located on one side of the speed control mechanism 2. Specifically, the cable body 1 passes through the speed control mechanism 2 and the detection mechanism in sequence. That is, the cable body 1 passes through the speed control mechanism 2 first and then the detection mechanism. Even if other materials adhere to the cable body 1 during movement, they will be stopped by the speed control mechanism 2 and will not collide with the detection mechanism.

[0032] For reference Figures 2-5 There are two testing mechanisms, which are arranged opposite to each other. Each testing mechanism contains several testing wheels 3, connecting plates 4, and testing shells 5. The multiple testing wheels 3 are arranged in a circular array around the center line of the testing shell 5. The testing wheels 3 have an arc-shaped part inside, which cooperates with the outer wall of the cable body 1. The testing wheels 3 are inserted into the connecting plates 4, and the connecting plates 4 are movably connected to the testing shell 5. The testing shell 5 contains a testing unit, which is used to measure the angle of the connecting plates 4 when they are raised and lowered.

[0033] Two sets of detection wheels 3 within the two detection mechanisms form a circular detection structure, which engages with the outer wall of the cable body 1. The two sets of detection wheels 3 within the two detection mechanisms can form a complete circular detection structure, allowing the cable body 1 to be contained within it. Thus, the evenly distributed detection wheels 3 on all parts of the cable body 1 can press against the outer wall of the cable body 1. When the cable body 1 becomes dented due to wear, the corresponding detection wheel 3 will move closer to the side of the cable body 1. The detection unit detects the displacement of the connecting plate 4 and the detection wheels 3, and judges the wear condition of the cable body 1 based on the displacement distance, thereby determining whether the cable body 1 is damaged.

[0034] Specifically, the end of the connecting plate 4 away from the detection wheel 3 is inserted into the rotating shaft, the rotating shaft and the detection shell 5 can rotate relatively, and the detection unit comprises an incremental encoder: the incremental encoder can record the number of pulses when the shaft rotates through an optical or magneto-electric sensor, and convert the number of pulses into an angle. The measurement steps are as follows: the encoder is coaxially connected with the rotating shaft (directly mounted or through a shaft coupling). The power supply is turned on and the counter / PLC / single-chip microcomputer is connected. When the rotating shaft rotates, the encoder outputs A / B phase pulse signals, so that the angle of the detection wheel 3 lifting and pressing can be calculated, and the actual wear condition of the cable body 1 can be judged.

[0035] More specifically, the detection mechanism further comprises an elastic assembly 6 and a support frame 7, the detection wheel 3 is connected with the connecting plate 4 through a bearing, the connecting plate 4 is provided with two, and the two connecting plates 4 are located on the two sides of the detection wheel 3, the elastic assembly 6 is installed between the connecting plate 4 and the detection shell 5, the elastic assembly 6 can adopt a spring, one end of the spring is connected with the connecting plate 4, and the other end of the spring is connected with the detection shell 5, the elastic assembly 6 can also adopt a clockwork mechanism, and the clockwork mechanism is installed on the rotating shaft. The elastic assembly 6 can provide pressure to the connecting plate 4, so that the detection wheel 3 at the end of the connecting plate 4 always adheres to the outside of the cable body 1.

[0036] It should be noted that the detection shell 5 is arranged on the support frame 7, the support frame 7 is provided with a horizontal plate, and the support frame 7 and the support in the speed control mechanism 2 are connected through the horizontal plate.

[0037] In summary: the tension cable slow release control device provided by the embodiment of the utility model, two groups of detection wheels 3 in the two detection mechanisms can form a complete circular detection structure, the detection mechanism receives the cable body 1, so that the detection wheels 3 uniformly distributed at each part of the cable body 1 can abut on the outer wall of the cable body 1, and the plurality of detection wheels 3 can cover the whole area of the outer wall of the cable body 1, when the cable body 1 is worn and appears a concave condition, the corresponding detection wheel 3 will move to the side close to the cable body 1, the displacement of the connecting plate 4 and the detection wheel 3 is detected by the detection unit, the wear condition of the cable body 1 is judged according to the displacement distance, so as to judge whether the cable body 1 is damaged.

[0038] The above disclosure is only a few specific embodiments of the utility model, but the embodiments of the utility model are not limited to this, any change that can be thought of by any person skilled in the art should fall within the protection scope of the utility model.
