The tower climbing power device comprises a supporting assembly, a traction rope, a driving assembly and a speed reduction assembly. The supporting assembly can move up and down in the height direction of the supporting assembly relative to the traction rope. The speed reduction assembly comprises a rotating wheel, a first rotating shaft, an elastic locking piece and a limiting piece. The pulling rope is in limiting sliding fit with the limiting piece and the rotating wheel. The rotating wheel is installed on the supporting assembly through a first rotating shaft so that the rotating wheel can rotate relative to the supporting assembly. And the elastic locking piece is connected with the rotating wheel. When the descending speed of the supporting assembly is smaller than or equal to the set speed, the traction rope drives the rotating wheel to rotate through the first convex teeth.

According to the tower climbing power device, slow speed reduction during falling is facilitated, and the safety of tower climbing operation is improved.

Description

Technical Field

[0001] This application relates to the field of power equipment, and in particular to tower climbing power units and tower climbing wearable devices. Background Technology

[0002] In power line maintenance, inspecting and replacing pole bases, conductors, and fittings are crucial steps in ensuring the normal operation and maintenance of transmission and distribution lines. Due to safety distance regulations, conductors are typically installed at the top of poles or towers, away from the ground and buildings. Therefore, routine maintenance and repair work often involves working at heights. Maintenance personnel must wear safety equipment and climb to the top of the poles or towers.

[0003] Related technologies provide tower climbing assistance devices to help maintenance personnel climb towers. These devices are generally equipped with a braking mechanism that directly stops the drive motor when the maintenance personnel descend too quickly, thereby locking the traction rope and preventing the maintenance personnel from falling.

[0004] However, the above-mentioned braking mechanism has the following shortcomings: directly stopping the drive motor can easily cause excessive jerk force on the traction rope, which can easily cause discomfort to maintenance personnel and can also easily damage the traction rope, or even cause the traction rope to break, exacerbating the rapid fall of maintenance personnel and posing a significant safety hazard. Utility Model Content

[0005] Therefore, it is necessary to provide a tower climbing power device and tower climbing wearable equipment to address the safety deficiencies in tower climbing power devices.

[0006] A tower climbing power unit, comprising:

[0007] Support components;

[0008] Tow rope;

[0009] A drive assembly is connected to the support assembly; the drive assembly is driven by the traction rope, enabling the support assembly to move up and down relative to the traction rope along the height direction of the support assembly.

[0010] The deceleration assembly includes a rotating wheel, a first rotating shaft, an elastic locking member, an elastic tensioning member, and a limiting member; the rotating wheel and the limiting member are disposed opposite to each other on both sides of the traction rope, so that the traction rope is limited and slidably engaged with the limiting member and the rotating wheel; the rotating wheel is mounted on the support assembly through the first rotating shaft, so that the rotating wheel can rotate relative to the support assembly; the elastic locking member is connected to the rotating wheel;

[0011] The outer side wall of the rotating wheel is provided with a plurality of first protruding teeth, which are arranged around the outer side wall of the rotating wheel in the circumferential direction. The first protruding teeth are used to abut against the traction rope. The inner side wall of the rotating wheel is provided with a plurality of second protruding teeth, which are arranged around the inner side wall of the rotating wheel in the circumferential direction. The elastic locking member is used to engage and lock with the second protruding teeth. The first protruding teeth are rotatable relative to the second protruding teeth.

[0012] Specifically, when the descent speed of the support assembly is less than or equal to the set speed, the traction rope slides with the first tooth, and the traction rope drives the rotating wheel to rotate through the first tooth, with the elastic locking member spaced apart from the second tooth; when the descent speed of the support assembly is greater than the set speed, the rotating wheel, under the action of centrifugal force, drives the elastic locking member to move in a direction close to the second tooth, so that the elastic locking member engages and locks with the second tooth, thereby locking the rotating wheel onto the support assembly.

[0013] In one embodiment, the elastic locking member includes a locking body and an elastic tension member, the locking body being used to engage with the second tooth; one end of the elastic tension member is connected to the rotating wheel, and the other end is connected to the locking body.

[0014] And / or, the deceleration assembly further includes a ratchet member, with a plurality of second convex teeth wound around the inner ring of the ratchet member; the elastic locking member is disposed on the inner ring of the ratchet member; the rotating wheel is provided with a mounting cavity; the ratchet member is connected to the rotating wheel, and the ratchet member and the inner sidewall of the rotating wheel are spaced apart; the rotating wheel can drive the ratchet member to rotate synchronously relative to the support assembly.

[0015] In one embodiment, the tower climbing power device further includes a spacing adjustment component; the spacing adjustment component is movably connected to at least one of the limiting member and the rotating wheel, and the spacing adjustment component is used to drive at least one of the limiting member and the rotating wheel to move, so that the spacing between the limiting member and the rotating wheel is adjustable.

[0016] In one embodiment, the spacing adjustment component includes a swing rod; one end of the swing rod is connected to the rotating wheel, and the other end is rotatably engaged with the support component, so that when the swing rod rotates relative to the support component, it can drive the rotating wheel to swing, thereby making the spacing between the rotating wheel and the limiting member adjustable.

[0017] In one embodiment, the drive assembly includes a first reel, a second reel, and a motor assembly; the first reel and the second reel are spaced apart; the motor assembly is for transmission connection with at least one of the first reel and the second reel; the traction rope is wound around the first reel and the second reel, the direction of the traction rope around the first reel is opposite to the direction of the traction rope around the second reel, the traction rope is telescopically movably disposed on the support assembly, and the traction rope is transmissionally connected to the first reel and the second reel, such that the first reel and the second reel drive the traction rope to telescopically move along the height direction, so that the support assembly can rise and fall relative to the traction rope along the height direction.

[0018] In one embodiment, the motor assembly includes a first motor and a second motor; the first motor is configured to be driven to the first reel to drive the first reel to rotate, and the second motor is configured to be driven to the second reel to drive the second reel to rotate; the first motor and the second motor rotate in opposite directions, such that the first reel and the second reel rotate in opposite directions.

[0019] In one embodiment, the limiting member includes a first guide wheel; the traction rope is limited between the first guide wheel and the rotating wheel, the first guide wheel is rotatably mounted on the support assembly, and the traction rope abuts against the first guide wheel so that the traction rope can drive the first guide wheel to rotate;

[0020] And / or, the tower climbing power unit further includes a second guide wheel, which is rotatably mounted on the support assembly. The second guide wheel is used to engage with the traction rope, so that the traction rope can drive the second guide wheel to roll.

[0021] In one embodiment, the tower climbing power unit further includes a guide assembly; the guide assembly includes a second rotating shaft and a third rotating shaft, the second rotating shaft and the third rotating shaft being arranged opposite to each other along a first direction, and the second rotating shaft and the third rotating shaft being rotatably disposed on the support assembly, the traction rope being inserted between the second rotating shaft and the third rotating shaft, and the traction rope being capable of guiding and cooperating with the second rotating shaft and the third rotating shaft; wherein, the first direction is intersecting the height direction.

[0022] In one embodiment, the maximum tilt angle between the first direction and the height direction is an obtuse angle.

[0023] A tower climbing wearable device includes a wearable component and a tower climbing power device as described in the above embodiments. The wearable component is connected to a support assembly and is raised and lowered along the height direction of the support assembly via the support assembly, thereby driving the wearable component to move up and down along the height direction.

[0024] In the aforementioned tower climbing power unit and tower climbing equipment, when the descent speed of the support component is less than or equal to the set speed, the traction rope slides with the first serration, causing the rotating wheel to roll relative to the traction rope. At this time, the speed at which the rotating wheel moves relative to the traction rope is not too fast. Because the rotation of the rotating wheel is relatively stable, it can drive the elastic locking element and the elastic tensioning element to maintain circular motion (which can be uniform or variable speed circular motion). The elastic locking element can be spaced apart from the second serration. Simultaneously, when the descent speed of the support component is less than or equal to the set speed, the rolling engagement between the rotating wheel and the traction rope does not generate significant resistance to the traction rope, which helps improve the tower climbing efficiency for maintenance personnel.

[0025] When the descent speed of the support assembly exceeds the set speed (which can be determined by the elastic properties of the elastic tension member or the distance between the elastic locking member and the second convex tooth, etc.), meaning there is a risk of the maintenance personnel falling, the support assembly, deceleration assembly, drive assembly, and the gravity of the maintenance personnel will cause the support assembly to descend rapidly relative to the traction rope. The rotating wheel will rotate rapidly relative to the traction rope, thereby causing the elastic locking member to also undergo rapid circular motion. When the rotation speed exceeds the limit, the elastic locking member will undergo centrifugal motion, causing it to overcome the elastic effect of the elastic tension member and deviate in the direction closer to the second convex tooth. The elastic locking member will engage and fix with the second convex tooth, achieving internal self-locking of the rotating wheel. The rotating wheel and the traction rope will directly change from rolling engagement to frictional contact engagement, increasing the frictional resistance between the rotating wheel and the traction rope, thereby achieving stable deceleration of the support assembly relative to the traction rope.

[0026] Once the maintenance personnel have adjusted their speed and are no longer falling, the descent speed of the support assembly returns to less than or equal to the set speed. Due to the elasticity of the elastic tension member, the elastic tension member will reset, causing the elastic locking member to reset in a direction away from the second convex tooth. This separates the elastic locking member from the second convex tooth, thereby unlocking the rotating wheel internally. The rotating wheel can continue to roll relative to the traction rope, minimizing the resistance of the rotating wheel to the traction rope and reducing the difficulty for maintenance personnel to climb the tower.

[0027] Thus, if and only if the descent speed exceeds the set speed, the engagement between the rotating wheel and the traction rope changes from a rolling engagement to a frictional engagement. This increases the frictional resistance between the rotating wheel and the traction rope to slow down the support components, thereby avoiding the jamming that occurs when the drive components are directly locked. This improves the smoothness of the deceleration process, reduces the risk of traction rope breakage, and enhances the safety of the tower climbing process. Attached Figure Description

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] See Figure 1 One embodiment of this application provides a tower climbing wearable device, including a tower climbing power unit 100 and wearable components. The wearable components may be, but are not limited to, safety belts, clothing, etc., and are not subject to further restrictions here.

[0039] Specifically, such as Figures 1 to 2 As shown, the tower climbing power unit 100 includes a support assembly 110, a traction rope 120, a drive assembly 130, and a deceleration assembly 140.

[0040] The drive assembly 130 is connected to the support assembly 110. The drive assembly 130 is connected to the traction rope 120, so that the support assembly 110 can move up and down relative to the traction rope 120 along the height direction X of the support assembly 110.

[0041] like Figure 3 as well as Figure 4 As shown, the deceleration assembly 140 includes a rotating wheel 141, a first rotating shaft 142, an elastic locking member 143, and a limiting member 144. The rotating wheel 141 and the limiting member 144 are disposed opposite to each other on both sides of the traction rope 120, so that the traction rope 120 is in a limited sliding engagement with the limiting member 144 and the rotating wheel 141. The rotating wheel 141 is mounted on the support assembly 110 via the first rotating shaft 142, so that the rotating wheel 141 can rotate relative to the support assembly 110. At this time, since the drive assembly 130 will drive the support assembly 110 to move up and down in the height direction X, the rotating wheel 141 will be able to roll relative to the traction rope 120. The limiting member 144 can be a friction abutment member (which will not roll under the abutment and sliding action of the traction rope 120) or a rolling member (which rolls in engagement under the abutment and sliding action of the traction rope 120).

[0042] The elastic locking member 143 is connected to the rotating wheel 141. The outer wall of the rotating wheel 141 is provided with a plurality of first protrusions 141a, which are wound around the outer wall of the rotating wheel 141 in the circumferential direction. The first protrusions 141a are used to abut against the traction rope 120. The inner wall of the rotating wheel 141 is provided with a plurality of second protrusions 141b, which are wound around the inner wall of the rotating wheel 141 in the circumferential direction. The second protrusions 141b are used to lock into the elastic locking member 143. The elastic locking member 143 is also used to engage and lock into the second protrusions 141b. The first protrusions 141a are rotatable relative to the second protrusions 141b.

[0043] When the descent speed of the support assembly 110 is less than or equal to the set speed, the traction rope 120 slides with the first tooth 141a, and the traction rope 120 drives the rotating wheel 141 to rotate through the first tooth 141a. The elastic locking member 143 and the second tooth 141b are spaced apart. When the descent speed of the support assembly 110 is greater than the set speed, the rotating wheel 141, under centrifugal force, drives the elastic locking member 143 to move towards the second tooth 141b, causing the elastic locking member 143 to engage and lock with the second tooth 141b, thus locking the rotating wheel 141 onto the support assembly 110.

[0044] To facilitate understanding, the following sections will provide a detailed explanation of the motion reduction principle of the deceleration component 140.

[0045] When the descent speed of the support assembly 110 is less than or equal to the set speed, the traction rope 120 slides with the first tooth 141a, causing the rotating wheel 141 to roll relative to the traction rope 120. At this time, the speed at which the rotating wheel 141 moves relative to the traction rope 120 is not too fast. Because the rotation of the rotating wheel 141 is relatively stable, it can drive the elastic locking member 143 and the elastic tension member 1432 to maintain circular motion (which can be uniform or variable speed circular motion). The elastic locking member 143 can be spaced apart from the second tooth 141b. Simultaneously, when the descent speed of the support assembly 110 is less than or equal to the set speed, the rolling engagement of the rotating wheel 141 and the traction rope 120 will not generate significant resistance to the traction rope 120, which helps improve the efficiency of maintenance personnel climbing the tower.

[0046] When the descent speed of the support assembly 110 exceeds the set speed (the set speed can be determined by the elastic properties of the elastic tension member 1432, or by the distance between the elastic locking member 143 and the second convex tooth 141b, etc.), meaning there is a risk of the maintenance personnel falling, the support assembly 110, deceleration assembly 140, drive assembly 130, and the gravity of the maintenance personnel cause the support assembly 110 to descend rapidly relative to the traction rope 120, while the rotating wheel 141 rotates rapidly relative to the traction rope 120 (according to...). Figure 4 The rotation is rapid in the clockwise direction (as shown), which causes the elastic locking member 143 to also undergo rapid circular motion. When the rotation speed exceeds the limit, the elastic locking member 143 will undergo centrifugal motion, causing the elastic locking member 143 to overcome the elastic effect of the elastic tension member 1432 and deviate in the direction close to the second convex tooth 141b. The elastic locking member 143 engages and is fixed with the second convex tooth 141b, realizing the internal self-locking of the rotating wheel 141. The rotating wheel 141 and the traction rope 120 directly change from rolling engagement to friction abutment engagement, increasing the frictional resistance between the rotating wheel 141 and the traction rope 120, thereby realizing stable deceleration between the support component 110 and the traction rope 120.

[0047] Once the maintenance personnel have adjusted their speed and are no longer falling, the descent speed of the support component 110 returns to less than or equal to the set speed. Due to the elastic effect of the elastic tension member 1432, the elastic tension member 1432 will reset to drive the elastic locking member 143 to reset in a direction away from the second protrusion 141b, so that the elastic locking member 143 and the second protrusion 141b are separated, thereby realizing the internal unlocking of the rotating wheel 141 itself. The rotating wheel 141 can continue to roll relative to the traction rope 120, minimizing the movement resistance of the rotating wheel 141 relative to the traction rope 120, which helps to reduce the difficulty of the maintenance personnel climbing the tower.

[0048] Thus, if and only if the descent speed exceeds the set speed, the engagement between the rotating wheel 141 and the traction rope 120 changes from a rolling engagement to a frictional engagement. This increases the frictional resistance between the rotating wheel 141 and the traction rope 120 to decelerate the support assembly 110, thereby avoiding the jamming that occurs when the drive assembly 130 is directly locked. This improves the smoothness of the deceleration process, reduces the risk of the traction rope 120 breaking, and enhances the safety of the tower climbing process.

[0049] It should be noted that the elastic tension member 1432 in the above embodiments can be, but is not limited to, a compression spring, a stretching rubber, or other elastic member capable of directional stretching. Furthermore, the elastic locking member 143 can be composed of a torsion spring and a locking member, or a tension spring and a locking member, etc. In addition, the second convex tooth 141b can rotate synchronously with the rotating wheel 141 or rotate asynchronously; the former is not subject to excessive restrictions here.

[0050] In one embodiment, such as Figure 5 As shown, the elastic locking member 143 includes a locking body 1431 and an elastic tension member 1432. The locking body 1431 is used to engage with the second protrusion 141b. One end of the elastic tension member 1432 is connected to the rotating wheel 141, and the other end is connected to the locking body 1431. The locking body 1431 is connected to the support assembly 110 through the elastic tension member 1432. Thus, the provision of the elastic tension member 1432 allows the locking body 1431 to have a larger range of motion, thereby improving the efficiency of the locking engagement between the locking body 1431 and the second protrusion 141b, and improving the response speed of deceleration during descent.

[0051] In one embodiment, such as Figure 5 As shown, the deceleration assembly 140 also includes a ratchet member 145, with multiple second protrusions 141b wound around the inner ring of the ratchet member 145. An elastic locking member 143 is disposed on the inner ring of the ratchet member 145. The rotating wheel 141 has a mounting cavity. The ratchet member 145 is connected to the rotating wheel 141, and the ratchet member 145 and the inner sidewall of the rotating wheel 141 are spaced apart. The rotating wheel 141 can rotate relative to the ratchet member 145. Thus, by providing the second protrusions 141b on the ratchet member 145, it avoids directly setting them on the inner sidewall of the rotating wheel 141, reducing the processing difficulty. Furthermore, the outer sidewall of the ratchet member 145 is spaced apart from the inner sidewall of the rotating wheel 141, avoiding rolling friction between the ratchet member 145 and the rotating wheel 141, ensuring the rotation process of the rotating wheel 141, which is beneficial for maintenance personnel to climb the tower more smoothly and effortlessly.

[0052] In conjunction with any embodiment of the tower climbing power unit 100 described above, see back Figure 3 as well as Figure 4 The tower climbing power unit 100 also includes a spacing adjustment assembly 150. The spacing adjustment assembly 150 is movably connected to at least one of the limiting member 144 and the rotating wheel 141, and in this process, the traction rope 120 maintains abutment against the limiting member 144 and the rotating wheel 141. The spacing adjustment assembly 150 is used to move at least one of the limiting member 144 and the rotating wheel 141, making the spacing between the limiting member 144 and the rotating wheel 141 adjustable.

[0053] The spacing adjustment component 150 can either rotate or slide at least one of the limiting member 144 and the rotating wheel 141. Thus, by moving at least one of the limiting member 144 and the rotating wheel 141 through the spacing adjustment component 150, the spacing between them is adjustable. This facilitates the installation of traction ropes 120 of different sizes between the limiting member 144 and the rotating wheel 141, ensuring that traction ropes 120 of different sizes can engage with the rotating wheel 141 for deceleration when installed in the tower climbing power device 100 of this embodiment, thereby increasing the adaptability of the tower climbing power device 100.

[0054] In one embodiment, see back Figure 3 as well as Figure 4 The spacing adjustment assembly 150 includes a swing arm. One end of the swing arm is connected to the rotating wheel 141, and the other end is rotatably engaged with the support assembly 110. This allows the swing arm to rotate relative to the support assembly 110, thereby driving the rotating wheel 141 to swing and making the spacing between the rotating wheel 141 and the limiting member 144 adjustable. In this way, spacing adjustment is achieved through the rotation of the swing arm, eliminating the need for complex additional mechanisms, simplifying the overall structure, and reducing manufacturing costs and maintenance difficulty. Furthermore, the operation is intuitive, allowing maintenance personnel to quickly perform adjustments.

[0055] It should be noted that the rotatable connection between the other end of the swing arm and the support assembly 110 can be achieved through a rotating shaft or a connecting rod assembly, etc., without further limitation here.

[0056] Referring to any embodiment of the drive component 130 described above, see Figure 6 as well as Figure 7 As shown, the drive assembly 130 includes a first reel 131, a second reel 132, and a motor assembly 133. The first reel 131 and the second reel 132 are spaced apart. The motor assembly 133 is used for transmission connection with at least one of the first reel 131 and the second reel 132. The traction rope 120 is wound around the first reel 131 and the second reel 132, with the direction of the traction rope 120 around the first reel 131 opposite to the direction of the traction rope around the second reel 132 (i.e., part of the traction rope 120 is wound in an S-shape between the first reel 131 and the second reel 132), and the traction rope 120 is telescopically movably disposed on the support assembly 110. The traction rope 120 can be transmissionally connected to the first reel 131 and the second reel 132, so that the first reel 131 and the second reel 132 drive the traction rope 120 to telescopically move along the height direction X, so that the support assembly 110 can rise and fall relative to the traction rope 120 along the height direction X.

[0057] In one example scenario, the S-shaped structure of part of the traction rope 120 wrapped around the first reel 131 and the second reel 132 means that the traction rope 120 is wound from the outside of the first reel 131, wound between the first reel 131 and the second reel 132, then wound from the bottom of the first reel 131 to the top of the second reel 132, and then wound from the outside of the second reel 132, winding around the second reel 132 for more than half a turn before passing through, thus completing the installation of the traction rope 120.

[0058] To facilitate understanding, the following explanation will illustrate the lifting and lowering principle of the support component 110 in the height direction X, using the example of the drive component 130 driving the first winding wheel 131.

[0059] When the climber needs to ascend the tower, the drive assembly 130 can be rotated to drive the first reel 131 to rotate in the first direction Z (e.g., counterclockwise), so that the traction rope 120 has a sliding motion direction toward the second reel 132, thereby driving the second reel 132 to rotate in the second direction (e.g., clockwise), so that the traction rope 120 has a downward motion vector along the height direction X, and then the support assembly 110 drives the wearer to rise relative to the traction rope 120 along the height direction X, thereby enabling the climber to ascend the tower.

[0060] Accordingly, when the person climbing the tower needs to descend, the drive assembly 130 can be rotated to drive the first reel 131 to rotate in a second direction (such as clockwise), so that the traction rope 120 has a movement direction away from the sliding on the second reel 132, thereby driving the second reel 132 to rotate in a first direction Z (such as counterclockwise), so that the traction rope 120 has an upward movement vector along the height direction X, and then the support assembly 110 drives the wearer to descend relative to the traction rope 120 along the height direction X, thereby achieving a stable descent of the person climbing the tower.

[0061] Understandably, when the support assembly 110 is not raised and lowered smoothly due to factors such as the asynchronous winding of the first reel 131 and the second reel 132, the traction rope 120 can be wound in an S-shape around the first reel 131 and the second reel 132. This helps to increase the contact area between the reel assembly and the traction rope 120, increase the friction between the two, and make the traction rope 120 lock into the reel assembly, thus improving the safety of tower climbing operations.

[0062] This facilitates multi-stage deceleration of the tower climbing power unit 100. Specifically, when the support component 110 is unstable during descent and the descent speed does not exceed the set speed, the traction rope 120 can be secured to the reel assembly through the winding friction between the traction rope 120 and the reel assembly, achieving initial deceleration. When the support component 110's descent speed exceeds the set speed, the deceleration component 140 can be engaged with the traction rope 120 and the reel assembly, maximizing the friction area and achieving advanced deceleration. This avoids direct braking of the drive component 130, achieving smooth deceleration and improving the safety of tower climbing operations.

[0063] It should be noted that the number of driver components 130 can be one or more, and no further restrictions are imposed here.

[0064] Combination Figures 2 to 3 As shown, in conjunction with any embodiment of the drive component 130 described above, such as Figure 7 As shown, the drive assembly 130 includes a first motor 1331 and a second motor 1332. The first motor 1331 is connected to the first reel 131 to drive the first reel 131 to rotate, and the second motor 1332 is connected to the second reel 132 to drive the second reel 132 to rotate. The first motor 1331 and the second motor 1332 rotate in opposite directions, so that the first reel 131 and the second reel 132 rotate in opposite directions.

[0065] To facilitate understanding, the following detailed explanation will be provided in conjunction with the motion principle of the drive component 130 driving the reel assembly.

[0066] When climbers need to ascend the tower, the first motor 1331 can be rotated to drive the first reel 131 to rotate in a first rotational direction (e.g., counterclockwise), causing the traction rope 120 to slide towards the second motor 1332. The second motor 1332 then rotates to drive the second reel 132 to rotate in a second rotational direction (e.g., clockwise), giving the traction rope 120 a downward motion vector along the height direction X on the second motor 1332. This causes the support assembly 110 to lift the wearer relative to the traction rope 120 along the height direction X, thus enabling the climbers to ascend the tower.

[0067] Accordingly, when the climber needs to descend, the second motor 1332 can be rotated to drive the second reel 132 to rotate in a first rotational direction (e.g., counterclockwise), causing the traction rope 120 to slide towards the first reel 131. Meanwhile, by rotating the first motor 1331 to drive the first reel 131 to rotate in a second rotational direction (e.g., clockwise), the traction rope 120 can have an upward motion vector along the height direction X on the first motor 1331. This causes the support assembly 110 to lower the wearer relative to the traction rope 120 along the height direction X, achieving a stable descent of the climber.

[0068] Thus, in this embodiment, the driving force on the traction rope 120 is increased by driving the first reel 131 with the first motor 1331 and the second reel 132 with the second motor 1332, thereby saving more effort. Furthermore, the first motor 1331 and the second motor 1332 can rotate in opposite directions, which can better pull the traction rope 120, improve the tension of the traction rope 120, and thus optimize the accuracy of transmission.

[0069] In some implementations, see back Figure 3 as well as Figure 4 The limiting component 144 includes a first guide wheel 1441. The traction rope 120 is positioned between the first guide wheel 1441 and the rotating wheel 141. The first guide wheel 1441 is rotatably mounted on the support assembly 110, and the traction rope 120 abuts against the first guide wheel 1441, enabling the traction rope 120 to drive the first guide wheel 1441 to rotate. Thus, the first guide wheel 1441 can rotate relative to the support assembly 110, allowing the traction rope 120 to drive the first guide wheel 1441 to rotate during movement. This converts sliding friction into rolling friction, significantly reducing the frictional resistance between the traction rope 120 and the first guide wheel 1441, which helps reduce wear on the traction rope 120 and extends the service life of both the first guide wheel 1441 and the traction rope 120. Simultaneously, the rotational engagement of the first guide wheel 1441 makes the movement of the traction rope 120 smoother, reducing energy loss and improving the smoothness of the tower climbing power unit 100's movement.

[0070] In addition, both the first guide wheel 1441 and the rotating wheel 141 can roll in conjunction with the traction rope 120, making the traction rope 120 more evenly stressed during movement, avoiding local stress concentration or shaking, thereby improving the operational stability and reliability of the tower climbing process.

[0071] To improve the motion stability of the support assembly 110 relative to the traction rope 120, in some embodiments, see back Figure 3 as well as Figure 4The tower climbing power unit 100 also includes a guide assembly 160. The guide assembly 160 includes a second rotating shaft 161 and a third rotating shaft 162, which are arranged opposite each other along a first direction Z. The second rotating shaft 161 and the third rotating shaft 162 are rotatably mounted on the support assembly 110. A traction rope 120 is inserted between the second rotating shaft 161 and the third rotating shaft 162, and the traction rope 120 is capable of guiding and engaging with the second rotating shaft 161 and the third rotating shaft 162. The first direction Z intersects the height direction X.

[0072] Thus, the second rotating shaft 161 and the third rotating shaft 162 are arranged opposite each other along the first direction Z, and the traction rope 120 is inserted between them and guided by them. This allows the traction rope 120 to be doubly limited and guided during movement, preventing the traction rope 120 from deviating, shaking, or derailing, thereby improving the movement stability of the support assembly 110 relative to the traction rope 120. Furthermore, the rotational arrangement of the second rotating shaft 161 and the third rotating shaft 162 allows the traction rope 120 to drive the second rotating shaft 161 or the third rotating shaft 162 to rotate during movement, converting sliding friction into rolling friction, reducing the frictional resistance between the traction rope 120 and the rotating shaft, reducing energy loss, and improving the smoothness of the movement of the traction rope 120.

[0073] It should be noted that the intersection of the first direction Z and the height direction X can be set to be perpendicular to each other or non-perpendicular.

[0074] In one implementation, see back Figure 3 The guide assembly 160 also includes a first body 163 and a second body 164. The first body 163 and the second body 164 are arranged opposite each other along the length direction Y of the support assembly 110, and the second rotating shaft 161 and the third rotating shaft 162 are both inserted between the first body 163 and the second body 164. The first direction Z intersects both the height direction X and the length direction Y. This arrangement makes the guide assembly 160 more regular and improves the aesthetics of the tower climbing power unit 100.

[0075] Furthermore, in other embodiments, the maximum tilt angle between the first direction Z and the height direction X is an obtuse angle. Specifically, the second rotating shaft 161 is disposed close to the support assembly 110, and the third rotating shaft 162 is disposed away from the support assembly 110. Along the direction from the second rotating shaft 161 to the third rotating shaft 162, the third rotating shaft 162 is tilted away from the height direction X. This differs from the guide assembly 160 being perpendicular to the support assembly 110, avoiding excessive thickness of the support assembly 110, and ensuring that the distance between the second rotating shaft 161 and the third rotating shaft 162 is sufficiently large to meet the requirements for limiting the movement of the traction rope 120.

[0076] Furthermore, in one example, from the second pivot 161 to the third pivot 162, the third pivot 162 is inclined away from the drive assembly 130. This allows the guide assembly 160 and the support assembly 110 to be positioned to avoid interference between the support assembly 110 and the guide assembly 160, ensuring that the distance between the second pivot 161 and the third pivot 162 is sufficiently large to guide and cooperate with traction ropes 120 of different sizes.

[0077] In some embodiments, see back Figures 3 to 5 As shown, the tower climbing power unit 100 also includes a second guide wheel 170, which is rotatably mounted on the support assembly 110. The second guide wheel 170 is used to engage with the traction rope 120, allowing the traction rope 120 to drive the second guide wheel 170 to roll. Thus, the second guide wheel 170 reduces the sliding friction resistance when the traction rope 120 contacts the support assembly 110, instead converting it into rolling friction resistance through the engagement of the second guide wheel 170 with the traction rope 120. This improves the efficiency of the tower climbing operation and reduces effort.
