[0029] like Figures 2 to 4 As shown, it is a traction mechanism suitable for a high-altitude tower climbing assisting device according to an embodiment of the present invention.

[0030] See also Figure 2-Figure 4 As shown, the traction mechanism 10 suitable for the high-altitude tower climbing assist device in an embodiment of the present invention includes a base plate 11, a reel assembly 12, a rotating shaft assembly 13, an energy storage assembly 15 and a drive assembly 14. The rotating shaft assembly 13 includes a rotating shaft 131. The reel assembly 12 and the rotating shaft 131 are both rotatably mounted on the base plate 11, and the reel assembly 12 surrounds the circumference of the rotating shaft 131. The energy storage assembly 15 includes a coil spring box 151 and a volute spring 152. The coil spring box 151 is connected to the reel assembly 12. An opening is provided at the bottom of the coil spring box 151. The first end of the rotating shaft 131 passes through the opening and is provided in the coil spring box 151. The volute spring 152 is provided in the coil spring box 151. One end of the volute spring 152 is connected to the coil spring box 151, and the other end is connected to the first end of the rotating shaft 131. The drive assembly 14 is connected to the second end of the rotating shaft 131.

[0031] The method of using the high-altitude tower climbing assisting device of this embodiment is as follows:

[0032] During the ascent process, the rope is first wound around the reel assembly 12. The drive assembly 14 is then activated, driving the shaft 131 to rotate. This rotation of the shaft 131 also rotates one end of the spiral spring 152 in the coil spring box 151, twisting the spiral spring 152 and storing elastic potential energy. The coil spring box 151 then rotates the reel assembly 12, reeling the rope until the rope reaches a preset traction force of 200N, thereby offsetting the load on the climber and reducing the strain on the climber. If the climber continues to ascend, the device will continue to assist the climber with a constant traction force of up to 200N, with the speed varying with the climber's speed, up to a maximum of 25m / min. If the climber needs to stop for a short rest, the device automatically stops, but maintains the maximum traction force to tighten the rope. While the drive assembly 14 provides power, the spiral spring 152 twists and stores energy. When traction is required, the elastic potential energy stored in the spiral spring 152 is released, enabling the traction mechanism 10 to respond more promptly.

[0033] Descending process: Turn off the drive component 14, the high-altitude tower climbing assist device will follow the descent when it is subjected to a downward pull, and provide a resistance slightly greater than the weight of the high-altitude tower climbing assist device itself to offset the load brought by the equipment and clothing during the process of personnel descending the tower. When there is no downward pull, it can stop at the current position.

[0034] The traction mechanism 10 of the present invention is provided with a reel assembly 12, a drive assembly 14 and a rotating shaft assembly 13, and is matched with an energy storage assembly 15. When a traction operation is required, the spiral spring 152 can quickly release the stored energy, so that the traction mechanism 10 can respond to the demand more promptly, and the traction response is quick and sensitive.

[0035] See also Figure 2 As shown, in certain embodiments, for example, the coil spring box 151 is formed with a first clamping opening 1511 adapted to the spiral spring 152, and the top of the rotating shaft assembly 13 is recessed to form a second clamping opening 1311 adapted to the spiral spring 152. One end of the spiral spring 152 is clamped in the first clamping opening 1511, and the other end is clamped in the second clamping opening 1311. Through the design of the clamping opening, the traction mechanism 10 can maintain the position of the spiral spring 152 stable, effectively transmit the torsional force, and ensure that the stored energy can be quickly released when needed, thereby achieving efficient traction operation.

[0036] See also Figure 2-Figure 3 As shown, in certain embodiments, illustratively, the coil spring box 151 includes a coil spring frame 1512 and a coil spring cover 1513, and the coil spring frame 1512 and the coil spring cover 1513 are screwed together. The coil spring frame 1512 is formed with a first clamping opening 1511, and the coil spring box 151 can be opened relatively easily to replace or repair the spiral spring 152 when necessary, and the screw connection can ensure the sealing and stability of the coil spring box 151, thereby effectively fixing the position of the coil spring frame 1512 and the coil spring cover 1513 to prevent loosening or falling off during operation.

[0037] See also Figure 2-Figure 5 As shown, in some embodiments, illustratively, the rotating shaft assembly 13 also includes an upper fixing ring 132, a lower fixing ring 133, an upper bearing 134, a lower bearing 135 and a first connecting member 136, the upper fixing ring 132 is installed on the lower fixing ring 133, the lower fixing ring 133 is installed on the base plate 11, and the upper fixing ring 132, the lower fixing ring 133 and the base plate 11 are connected by the first connecting member 136, the upper bearing 134 and the lower bearing 135 are respectively sleeved on the rotating shaft 131, and the upper bearing 134 is installed on the upper fixing ring 132, and the lower bearing 135 is installed on the lower fixing ring 133. This design can effectively support and maintain the stable operation of the rotating shaft assembly 13.

[0038] Furthermore, the reel assembly 12 includes an upper reel 121, a lower reel 122, an upper rotating shaft slip ring 123, a lower rotating shaft slip ring 124 and a second connecting piece 125. The upper rotating shaft slip ring 123 is sleeved on the upper fixing ring 132, and the lower rotating shaft slip ring 124 is sleeved on the lower fixing ring 133, and an annular groove 127 is formed between the upper rotating shaft slip ring 123 and the lower rotating shaft slip ring 124. The upper reel 121 and the lower reel 122 are clamped in the annular groove 127, and the coil spring box 151, the upper reel 121 and the lower reel 122 are connected by the second connecting piece 125. The reel assembly 12 can effectively fix the reel and connect it to the rotating shaft 131, while ensuring the coordinated movement between the coil spring box 151, the upper reel 121 and the lower reel 122. This design enables the reel to rotate smoothly and maintain stability with the rotating shaft 131.

[0039] Furthermore, a first contact surface 1211 is provided on the side of the upper reel 121 facing the lower reel 122, and the first contact surface 1211 is inclined upward in the direction away from the rotating shaft 131. A second contact surface 1221 is provided on the side of the lower reel 122 facing the upper reel 121, and the second contact surface 1221 is inclined downward in the direction away from the rotating shaft 131. Both the first contact surface 1211 and the second contact surface 1221 are provided with a plurality of protrusions 126. The first contact surface 1211 and the second contact surface 1221 are used to contact the pull rope. The inclined first contact surface 1211 and the second contact surface 1221 can guide the pull rope to contact the reel and ensure that the contact area is as large as possible, thereby improving the transmission efficiency and reliability.

[0040] Furthermore, the upper reel 121 is arranged in a Z shape, and the upper reel 121 includes a contact portion 1212, a connecting portion 1213 and a clamping portion 1214. The contact portion 1212 and the clamping portion 1214 are respectively arranged on both sides of the connecting portion 1213. The contact portion 1212 is provided with a first contact surface 1211, and the ridge 126 extends from the connecting portion 1213 to the edge of the contact portion 1212. The clamping portion 1214 is clamped in the annular groove 127. The structure of the lower reel 122 is the same as that of the upper reel 121, and the contact portion 1212 of the lower reel 122 is provided with a second contact surface 1221.

[0041] See also Figure 1 、 Figure 3-Figure 4As shown, in some embodiments, exemplarily, the drive assembly 14 includes a planetary actuator 141, a driving sprocket 142, a driven sprocket 143 and a chain 144, the planetary actuator 141 is mounted on the first side of the substrate 11, and the output end of the planetary actuator 141 passes through the substrate 11 and is arranged on the second side of the substrate 11, the driving sprocket 142 is arranged at the output end of the planetary actuator 141, the second end of the rotating shaft 131 passes through the substrate 11 and is arranged on the second side of the substrate 11, the driven sprocket 143 is arranged at the second end of the rotating shaft 131, the chain 144 is wrapped around the driving sprocket 142 and the driven sprocket 143, and the rotating shaft 131 is driven by indirect transmission, so that the planetary actuator 141 can be arranged next to the reel assembly 12 and the energy storage assembly 15, rather than on the axial direction of the reel assembly 12 and the energy storage assembly 15, thereby making the overall layout of the traction mechanism 10 lighter, and at the same time helping to reduce the overall size and weight of the system.

[0042] Specifically, the planetary actuator 141 includes a sun gear, planetary gears, a planetary carrier and an inner ring gear. The sun gear serves as an input shaft, and drives the rotation of the rotating shaft 131 through the movement of the planetary gears and the planetary carrier, and finally outputs torque to the rotating shaft 131.

[0043] It is understandable that the drive assembly 14 can drive the rotating shaft 131 to rotate by belt transmission in addition to driving the rotating shaft 131 to rotate by chain transmission. Specifically, the drive assembly 14 includes a planetary actuator 141, a driving wheel (not shown), a driven wheel (not shown) and a synchronous belt (not shown). The planetary actuator 141 is mounted on the first side of the base plate 11, and the output end of the planetary actuator 141 passes through the base plate 11 and is provided on the second side of the base plate 11. The driving wheel is provided at the output end of the planetary actuator 141. The second end of the rotating shaft 131 passes through the base plate 11 and is provided on the second side of the base plate 11. The driven wheel is provided at the second end of the rotating shaft 131, and the synchronous belt is wrapped around the driving wheel and the driven wheel.

[0044] It is understandable that, in addition to using the planetary actuator 141 as a power source, the driving assembly 14 may also use a servo motor or other power sources.

[0045] It is understandable that the driving assembly 14 can also drive the rotating shaft 131 to rotate by direct driving.

[0046] See also Figure 1-Figure 5 As shown, the present invention also provides a high-altitude tower climbing assist device, including an upper cover 20, a bottom cover 30 and a traction mechanism 10. The structure of the traction mechanism 10 is as described above and will not be repeated here. The upper cover 20 is arranged on the first side of the substrate 11 and is snap-connected to the substrate 11. The bottom cover 30 is arranged on the second side of the substrate 11 and is detachably connected to the substrate 11. The reel assembly 12 and the energy storage assembly 15 are arranged in a cavity formed by the upper cover 20 and the substrate 11.

[0047] Specifically, the driving sprocket 142 , the driven sprocket 143 and the chain 144 are disposed in a cavity formed by the bottom cover 30 and the base plate 11 .

[0048] Specifically, the upper cover 20 and the base plate 11 can be connected using a conventional snap-fit ​​connection method. For example, a spring snap is provided on the base plate 11, and a corresponding groove is provided on the upper cover 20. The connection and disconnection are achieved by compressing and releasing the spring. In another example, a lock is provided on the base plate 11, and a corresponding lock hole is provided on the upper cover 20.
