[0030] like Figures 1 to 6 As shown, it is a high-altitude tower climbing assisting device according to an embodiment of the present invention.

[0031] See also Figures 1-4 As shown, the high-altitude tower climbing assisting device of the embodiment of the present invention includes a traction mechanism 10 and an anti-slip mechanism 20, the traction mechanism 10 includes a base plate 11, a reel assembly 12, a rotating shaft assembly 13, an energy storage assembly 15 and a driving 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 spiral spring 152, the coil spring box 151 is connected to the reel assembly 12, the bottom of the coil spring box 151 is provided with an opening, the first end of the rotating shaft 131 passes through the opening and is arranged in the coil spring box 151, the spiral spring 152 is arranged in the coil spring box 151, and one end of the spiral 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 driving assembly 14 is connected to the second end of the rotating shaft 131, and the anti-slip mechanism 20 The first anti-stripping group 21 and the second anti-stripping group 22 are respectively located on both sides of the reel assembly 12. The first anti-stripping group 21 includes a guide frame 211, a first rope pulley 212, a second rope pulley 213, a movable gear rod 214 and a spring pin 215. The guide frame 211 is arranged on the base plate 11. The guide frame 211 is provided with a spring pin hole 2111 adapted to the spring pin 215. The first rope pulley 212 and the second rope pulley 213 are arranged on the guide frame 211, and a rope passing gap for the pull rope to pass through is formed between the first rope pulley 212 and the second rope pulley 213. The movable gear rod 214 is swingably arranged on the guide frame 211 and is located on the side of the rope passing gap away from the reel assembly 12. The spring pin 215 is arranged on the guide frame 211 and extends out of the spring pin hole 2111 to abut against the swinging end of the movable gear rod 214. The structure of the second anti-stripping group 22 is the same as that of the first anti-stripping group 21.

[0032] Specifically, an inclined surface is provided on one end of the spring pin 215 facing the movable lever 214 , so that the movable lever 214 can be smoothly pushed when moving.

[0033] It can be understood that the high-altitude tower climbing assisting device of this embodiment is used in conjunction with a wearable device. When in use, the high-altitude tower climbing assisting device is fixed on the wearable device.

[0034] The method of using the high-altitude tower climbing assisting device of this embodiment is as follows:

[0035] Ascending process: First press the spring pin 215 to open the movable lever 214, then pass the tension rope through the rope gap and wrap it around the reel assembly 12, then close the movable lever 214, and finally start the drive assembly 14. The drive assembly 14 drives the rotating shaft 131 to rotate. The rotation of the rotating shaft 131 drives one end of the spiral spring 152 in the coil spring box 151 to rotate together, causing the spiral spring 152 to be twisted and store elastic potential energy. The coil spring box 151 drives the reel assembly 12 to rotate and reel the rope until the rope is tightened to a preset traction force of 200N to offset the load on the personnel and reduce the burden on the personnel climbing the tower. If the personnel continue to climb at this time, the equipment will continue to assist the personnel in climbing with a constant traction force of up to 200N, and the speed will change with the speed of the personnel, with a maximum of no more than 25m / min; if the personnel need to stop for a short rest in the middle of the process, the equipment will automatically stop, but will maintain the maximum traction force to tension the rope. While the drive assembly 14 provides power, the volute spring 152 will be twisted and store energy; when a traction operation is required, the elastic potential energy stored in the volute spring 152 will be released, and the traction mechanism 10 can respond to the demand more promptly.

[0036] Descending process: Turn off the drive assembly 14. When the device is subjected to a downward pull, it will descend and provide a resistance slightly greater than the weight of the device itself to offset the load brought by the device and clothing when the personnel descend the tower. When there is no downward pull, the device can stop at the current position.

[0037] The high-altitude tower climbing assisting device of the embodiment 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. Moreover, the high-altitude tower climbing assisting device is also provided with an anti-slip mechanism 20. By clamping the pull rope through the anti-slip mechanism 20, the pull rope can be prevented from detaching from the reel assembly 12 during the traction process, which is safer.

[0038] See also Figure 2As 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.

[0039] See also Figure 2-Figure 4 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.

[0040] See also Figure 2-Figure 4 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.

[0041] 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.

[0042] 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.

[0043] 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 first clamping portion 1214. The contact portion 1212 and the first 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. The ridge 126 extends from the connecting portion 1213 to the edge of the contact portion 1212. The first 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. The contact portion 1212 of the lower reel 122 is provided with a second contact surface 1221.

[0044] See also Figures 1-4 As 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.

[0045] 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.

[0046] 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 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.

[0047] 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.

[0048] It is understandable that the driving assembly 14 can also drive the rotating shaft 131 to rotate by direct driving.

[0049] See also Figure 1 and Figure 6 As shown, in some embodiments, for example, the guide frame 211 includes a base 2112, a first mounting seat 2113 and a second mounting seat 2114, the base 2112 is installed on the substrate 11, the first mounting seat 2113 and the second mounting seat 2114 are arranged on the base 2112 at intervals, the first mounting seat 2113 and the second mounting seat 2114 are both provided with a first mounting portion 21131 and a second mounting portion 21132 arranged at intervals from top to bottom, the second mounting portion 21132 of the first mounting seat 2113 is provided with a pin hole 2111, the first rope pulley 212 is rotatably arranged between the first mounting portion 21131 of the first mounting seat 2113 and the base 2112, and the second rope pulley 213 is rotatably arranged on the first mounting portion 21131 of the second mounting seat 2114 The movable lever 214 is rotatably arranged between the first mounting portion 21131 and the second mounting portion 21132 of the second mounting seat 2114, and the other end is movably arranged between the first mounting portion 21131 and the second mounting portion 21132 of the first mounting seat 2113.

Through the combination of the base 2112, the first mounting seat 2113 and the second mounting seat 2114, a relatively stable support structure can be provided, which is beneficial to the stability of the entire guide system. Through the arrangement of the first rope pulley 212 and the second rope pulley 213, and the design of the movable lever 214, a relatively stable rope transmission effect can be achieved.
