Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and in particular to a power construction line tightening device. Background Art

[0002] During power engineering operations, cables are manually installed on utility poles or towers, and then tensioned using a power construction tensioner to reduce sag caused by gravity, suppress wind-induced vibration, and avoid uneven cable tension distribution that can cause hardware wear or breakage.

[0003] In the prior art, when using a power construction cable tensioner, a power worker first secures one end of the cable tensioner to a utility pole or pylon, releasing the cable's traction rope. A cable tensioning clamp, attached to the end of the traction rope, is then clamped onto the cable. During the clamping process, sufficient distance must be maintained between the traction rope and the pole or pylon for the clamp to move, ensuring that the cable can be tightened during the tightening of the traction rope.

[0004] In actual operation, the cable tensioning process often fails to reach the desired tension even after the traction rope is fully retracted due to insufficient spacing between the tensioning clamp and the utility pole or tower. In this case, the power worker needs to initially secure the cable before removing the tensioning clamp, releasing the traction rope, and adjusting the position of the tensioning clamp to facilitate re-tensioning. Summary of the Invention

[0005] The invention discloses a power construction tightening device to solve the technical problem in the related art that the power construction tightening device is prone to multiple fixation of the cable and the tightening device, and repeated manual release of the traction rope.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] The power construction tensioning device provided in some embodiments of the present application includes: a housing, a traction rope, an energy storage mechanism, a first wire clamp, and a reeling mechanism and a second wire clamp arranged in the housing. The energy storage mechanism is arranged between the first wire clamp and the second wire clamp, and the first wire clamp is connected to the reeling mechanism through the traction rope. The distance between the first wire clamp and the second wire clamp is a first distance. When the first distance is greater than a first preset value, the first wire clamp clamps and fixes the cable, the second wire clamp slides with the cable, and the reeling mechanism is in a first state and can rotate unidirectionally in a first clockwise direction and drive the traction rope to be reeled into the housing, so that the first wire clamp approaches the second wire clamp and stores energy in the energy storage mechanism. When the first distance is less than or equal to the first preset value, the first wire clamp slides with the cable, the second wire clamp clamps and fixes the cable, and the reeling mechanism switches to a second state. The energy storage mechanism can drive the first wire clamp to move away from the second wire clamp and drive the reeling mechanism to rotate in a second clockwise direction.

[0008] In some embodiments, when the first spacing is less than or equal to a first preset value, the first wire clamp and / or the energy storage mechanism may act on the winding mechanism, causing the winding mechanism to switch from the first state to the second state.

[0009] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0010] In the electric power construction tensioning device provided by the present application, during the process of the first wire clamp clamping the cable to tighten, the reeling mechanism reels the traction rope, and uses the traction rope to pull the first wire clamp to drive the cable to tighten. At the same time, the process of the first wire clamp and the second wire clamp approaching each other will compress the energy storage mechanism, causing the energy storage mechanism to store energy. Specifically, the reeling mechanism can only rotate in one direction in the first state to avoid the energy of the energy storage mechanism from being released. When the first wire clamp approaches the second wire clamp to a preset distance, the reeling mechanism will be triggered to switch to the second state. After the reeling mechanism switches to the second state, the reeling mechanism can already rotate in both directions. At this time, the energy storage mechanism can release energy, and the energy released by the energy storage mechanism can move the first wire clamp in a direction away from the second wire clamp. In this process, the traction rope reeled in by the reeling mechanism is also released.

[0011] Moreover, in the process of releasing energy by the energy storage mechanism, the second wire clamp and the cable are already in a clamped and fixed state, so the cable can be prevented from loosening, and the first wire clamp moves along the cable in the direction away from the second wire clamp. After the energy released by the energy storage structure is released, the traction rope can be rewound by the reeling mechanism again, and the above steps can be repeated. During the whole process, the operator only needs to operate the reeling mechanism to maintain the reeling action, thereby avoiding the pulling stroke of the traction rope limiting the cable tensioning movement distance and multiple disassembly and assembly of the cable and the power construction tensioning device. In addition, the power construction tensioning device provided this time can realize the automatic release of the traction rope under the action of the energy storage mechanism during the cable tensioning process, without the need for manual operation to release it, which is beneficial to simplify the cable operation steps and improve the cable tensioning efficiency.

DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0039] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0040] The following is combined with Figures 1 to 24 , the electric power construction tightening device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0041] Reference Figure 1 and Figure 11 This application provides a power construction line tensioning device. The power construction line tensioning device includes a housing 100, a traction rope 200, an energy storage mechanism 300, a first wire clamp 400, and a reeling mechanism 500 and a second wire clamp 600 disposed on the housing 100. The housing 100 is a basic structural component that provides a mounting base for other components. For example, the traction rope 200 may be, but is not limited to, a steel rope, a nylon rope, or a ribbon rope.

[0042] Reference Figure 1 The energy storage mechanism 300 is disposed between the first wire clamp 400 and the second wire clamp 600, and the first wire clamp 400 is connected to the winding mechanism 500 via the traction rope 200. Optionally, the energy storage mechanism 300 may be, but is not limited to, an elastic energy storage mechanism.

[0043] Reference Figures 2 to 5 The distance between the first clamp 400 and the second clamp 600 is a first distance. When the first distance is greater than a first preset value, the first clamp 400 clamps and secures the cable 10. The second clamp 600 slides with the cable 10. Exemplarily, both the first clamp 400 and the second clamp 600 have a cable groove for accommodating the cable 10. Exemplarily, the first clamp 400 and the second clamp 600 can be adjusted to achieve a fixed or sliding fit between the first clamp 400 and the cable 10. The second clamp 600 can be adjusted to achieve a fixed or sliding fit between the second clamp 600 and the cable 10. In the first state, the reeling mechanism 500 can rotate unidirectionally in a first clockwise direction and drive the traction rope 200 to be reeled into the housing 100, causing the first clamp 400 to approach the second clamp 600 and store energy in the energy storage mechanism 300. Exemplarily, the reeling mechanism 500 is provided with a ratchet structure, which can achieve unidirectional rotation of the reeling mechanism 500. Specifically, when the reeling mechanism 500 is in the first state, the pawl of the ratchet mechanism engages with the ratchet wheel, so that the reeling mechanism 500 can only rotate in a first clockwise direction. The first clockwise direction can be either clockwise or counterclockwise. Specifically, the traction rope 200 can be wound around the reeling mechanism 500. In some embodiments, when the first clockwise direction is clockwise, the second clockwise direction is counterclockwise. In some embodiments, when the first clockwise direction is counterclockwise, the second clockwise direction is clockwise.

[0044] It should be noted that the first preset value can be set as needed. Specifically, those skilled in the art can set the first preset value based on the range of motion of the operator's arm to facilitate the operator's installation of the power construction tensioning device. Specifically, the size of the first preset value can be designed based on ergonomics and the arm length of most adults. For this reason, the embodiment of this application does not provide a distance description for the size of the first preset value.

[0045] In some embodiments, the structure of the winding mechanism 500 may be the same as the mechanism for winding the steel rope of the power construction tightening device in the prior art.

[0046] Main reference Figures 6 to 9 It can be inferred that when the first spacing is less than or equal to the first preset value, the first wire clamp 400 slides with the cable 10. The second wire clamp 600 clamps and fixes the cable 10. The winding mechanism 500 switches to the second state. The energy storage mechanism 300 can drive the first wire clamp 400 to move in a direction away from the second wire clamp 600, and drive the winding mechanism 500 to rotate along the second clockwise direction. The first clockwise direction is opposite to the first clockwise direction. Exemplarily, when the winding mechanism 500 switches to the second state, the pawl in the ratchet mechanism for realizing the unidirectional rotation of the winding mechanism 500 is separated from the ratchet, so that the rotation of the ratchet is no longer constrained by the pawl, and the winding mechanism 500 can rotate in the direction of releasing the traction rope 200.

[0047] In some embodiments, the first and second clamps 400 and 600 can employ a linked clamping structure to open or clamp the first and second clamps 400 and 600 in the direction of the force acting on the cable 10. For example, the first and second clamps 400 and 600 can employ a clamping mechanism used in conventional power construction tensioning devices for clamping and fixing the cable 10.

[0048] Reference Figure 1 、 Figure 2 and Figure 6 In the process of tensioning the cable 10 in the power construction tensioning device provided in the above embodiment, the operator rotates the winding mechanism 500 in the first clockwise direction, so that the traction rope 200 is wound around the winding mechanism 500, thereby pulling the first wire clamp 400 closer to the second wire clamp 600. Figure 3 Due to the pulling of the traction rope 200, the first wire clamp 400 clamps and secures the cable 10. Furthermore, when the reeling mechanism 500 reels the cable 10, the cable 10 is pulled from the first wire clamp 400 toward the second wire clamp 600. As a result, the force exerted by the cable 10 on the second wire clamp 600 causes the second wire clamp 600 to open, thereby achieving a sliding fit between the cable 10 and the second wire clamp 600.

[0049] When the first spacing is less than or equal to the first preset value, the second wire clamp 600 clamps and fixes the cable 10, which is beneficial for preventing the cable 10 from sliding under the action of gravity. In some embodiments, the cable 10 can slide relative to the second wire clamp 600 under the action of gravity, driving the second wire clamp 600 to clamp and fix the cable 10. In addition, the one-way rotation of the winding mechanism 500 is released, and the energy storage mechanism 300 releases energy, thereby pushing the first wire clamp 400 to move away from the second wire clamp 600. Exemplarily, the released energy of the energy storage mechanism 300 can act on the first wire clamp 400, and the friction between the first wire clamp 400 and the cable 10 can be used to open the first wire clamp 400. After the energy storage mechanism 300 completes the energy release, the first spacing is greater than the first preset value, and the above steps can be repeated.

[0050] Therefore, the electric power construction tensioning device provided by the above embodiment can avoid the operator from repeatedly disassembling and releasing the traction rope 200, which is beneficial to simplifying the operator's operation and improving the efficiency of the cable 10 tensioning operation. In addition, during the installation of the electric power construction tensioning device, the traction rope 200 can be reeled up first, and the first spacing can be ensured to be greater than the preset value. Specifically, when the operator first installs the first wire clamp 400, the position where the first wire clamp 400 cooperates with the cable 10 is at a second spacing from the tower line. The above embodiment is also beneficial to reducing the second spacing, thereby preventing the operator from deviating too far from the tower line, reducing the difficulty of installing the electric power construction tensioning device, and helping to ensure safety during the installation of the electric power construction tensioning device.

[0051] In some embodiments, when the first spacing is less than or equal to a first preset value, the first wire clamp 400 and / or the energy storage mechanism 300 may act on the winding mechanism 500, causing the winding mechanism 500 to switch from the first state to the second state. When the first spacing is less than or equal to the first preset value, at least a portion of the first wire clamp 400 and / or the energy storage mechanism 300 may abut against the winding mechanism 500, triggering the winding mechanism 500 to switch from the first state to the second state. Exemplarily, when the first spacing is less than or equal to the first preset value, at least one of the energy storage mechanism 300 and the first wire clamp 400 directly or indirectly pushes against a pawl that restricts unidirectional rotation of the winding mechanism 500, causing the pawl that restricts unidirectional rotation of the winding mechanism 500 to separate from its corresponding ratchet, thereby enabling the winding mechanism 500 to switch from the first state to the second state.

[0052] In some embodiments, an operator can manually adjust the reeling mechanism 500 to switch between the first state and the second state. It should be noted that the mechanism for reeling the steel rope in a cable tensioner in the prior art can be manually adjusted to switch between two states to achieve steel rope reeling and steel rope release.

[0053] In some embodiments, referring to Figures 20 to 21 The winding mechanism 500 includes a first pawl 510 disposed on the housing 100, a rope winding shaft 520 rotatably disposed on the housing 100, and a first ratchet 530 disposed on the rope winding shaft 520. When the winding mechanism 500 is in a first state, the first pawl 510 cooperates with the first ratchet 530 to restrict the rope winding shaft 520 from rotating in a second clockwise direction. When the winding mechanism 500 is in a second state, the first pawl 510 is separated from the first ratchet 530. When the first distance is less than or equal to a first predetermined value, the first clamp 400 and / or the energy storage mechanism 300 abuts against the first pawl 510, causing the first pawl 510 to separate from the first ratchet 530, allowing the first ratchet 530 and the rope winding shaft 520 to rotate in the second clockwise direction relative to the housing 100.

[0054] In some embodiments, referring to Figures 10 to 15 The energy storage mechanism 300 includes a linkage rod 320. The linkage rod 320 is movably disposed on the housing 100 and can switch between a first position and a second position relative to the housing 100. The winding mechanism 500 is in transmission connection with the linkage rod 320. When the linkage rod 320 moves to the first position, the linkage rod 320 can activate the winding mechanism 500 to switch to the second position.

[0055] In some embodiments, the second clamp 600 is transmission-connected to the linkage rod 320. When the linkage rod 320 moves toward the first position, the linkage rod 320 can act on the second clamp 600 to clamp and fix the cable 10.

[0056] In some embodiments, the second cable clamp 600 and the reeling mechanism 500 are both connected to the linkage rod 320, enabling the linkage rod 320 to simultaneously actuate the reeling mechanism 500 and the second cable clamp 600, thereby achieving synchronized state adjustment of the reeling mechanism 500 and the second cable clamp 600. This solution helps reduce the sliding displacement of the cable 10 relative to the second cable clamp 600 during the state switching of the reeling mechanism 500. In some embodiments, the linkage rod 320 first actuates the second cable clamp 600 to clamp and secure the cable 10, and then actuates the reeling mechanism 500 to switch from the first state to the second state.

[0057] In some embodiments, when the linkage rod 320 moves to the second position, the linkage rod 320 can act to switch the winding mechanism 500 to the first state.

[0058] In some embodiments, the second wire clamp 600 is in transmission connection with the linkage rod 320. When the linkage rod 320 moves to the second position, the linkage rod 320 can act on the second wire clamp 600 to switch to sliding engagement with the cable 10.

[0059] Reference Figure 20 and Figure 21 In some embodiments, a column 322 is provided on the linkage rod 320. The housing 100 has a guide groove. The column 322 can slide along the guide groove. Figure 21 As shown, the first pawl 510 of the winding mechanism 500 is located on the trajectory of the column 322 relative to the housing 100. For example, when the trigger member 330 drives the linkage rod 320 to move toward the winding mechanism 500, the column 322 can slide along the guide groove and push against the first pawl 510, so that the first pawl 510 can move or rotate away from the first ratchet 530, thereby switching the winding mechanism 500 from the second state to the first state. For example, when the linkage rod 320 acts to separate the first pawl 510 from the first ratchet 530, the distance between the first clamp 400 and the second clamp 600 is equal to the first preset value.

[0060] In some embodiments, Figures 11 to 16 The energy storage mechanism 300 further includes a first elastic member 310 and a trigger member 330. The first elastic member 310 is disposed between the first wire clamp 400 and the second wire clamp 600 to store energy by compressing the first elastic member 310. Exemplarily, one end of the first elastic member 310 abuts against the first wire clamp 400, and the other end abuts against the housing 100 and / or the second wire clamp 600. In some embodiments, the first elastic member 310 may be a coil spring. Preferably, the first elastic member 310 is sleeved on the traction rope 200 to guide the elastic deformation of the first elastic member 310 through the traction rope 200, thereby improving the reliability of the first elastic member 310.

[0061] When the first distance is less than or equal to the first preset value, one end of the trigger member 330 abuts against the first clamp 400 , and the other end abuts against the linkage rod 320 .

[0062] In some embodiments, referring to Figure 18 and Figure 11 , the trigger member 330 is slidably engaged with the housing 100 and the traction rope 200. Exemplarily, the first end of the trigger member 330 is slidably engaged with the housing 100, and the second end points to the first clamp 400. Optionally, when the first spacing is greater than the first preset value, the second end of the trigger member 330 is spaced apart from the first clamp 400. Exemplarily, as Figure 16As shown, the trigger member 330 can be a cylindrical structure, and the first elastic member 310 is disposed in the trigger member 330. Further optionally, the first end of the trigger member 330 has a push block, and the trigger member 330 is stopped by the push block and the linkage rod 320.

[0063] In some embodiments, reference Figure 12 and Figure 15 As shown, the linkage rod 320 has a mounting groove 321. The second wire clamp 600 includes a second clamping arm 610 and a second clamping block 620. One end of the second clamping arm 610 is rotatably connected to the second clamping block 620, and the extension direction of the other end of the second clamping arm 610 is inclined relative to the movement direction of the linkage rod 320, and at least a portion of the second clamping arm 610 is located in the mounting groove 321. The middle portion of the second clamping arm 610 is rotatably engaged with the housing 100. During the energy storage process of the energy storage mechanism 300, the linkage rod 320 moves along the first direction, and the linkage rod 320 can drive the second clamping arm 610 to rotate along the first clockwise direction through the groove wall on the first side of the mounting groove 321, so as to drive the second clamping block 620 to clamp and fix the cable 10. During the movement of the linkage rod 320 in the second direction, the linkage rod 320 can drive the second clamping arm 610 to rotate along the second clockwise direction through the groove wall on the second side of the installation groove 321, so as to drive the second clamping block 620 to switch to sliding cooperation with the cable 10, and the first direction is opposite to the second direction.

[0064] In the above embodiment, the linkage rod 320 can actively drive the second wire clamp 600 to clamp the cable 10 through the installation slot 321, and can also drive the second wire clamp 600 to open through the slot wall of the installation slot 321, so that the second wire clamp 600 and the cable 10 are slidably matched.

[0065] In some embodiments, the second clamp 600 is further provided with a torsion spring to drive the second clamp 600 to open. For example, the torsion spring can be connected between the second clamping arm 610 and the housing 100 to drive the second clamping arm 610 to rotate relative to the housing 100 in the second clockwise direction.

[0066] In some embodiments, the power construction tightening device further includes a handle 700. Figures 20 to 22 The handle 700 is connected to the winding mechanism 500 and is used to drive the winding mechanism 500 to rotate. Optionally, the handle 700 can be connected to the winding mechanism 500 through a second ratchet mechanism 1200.

[0067] Exemplarily, the second ratchet mechanism 1200 includes a second pawl 1210 and a second ratchet 1220. The second ratchet 1220 is disposed on the winding mechanism 500. Specifically, the second ratchet 1220 is fixedly disposed on the winding mechanism 500 and is coaxially disposed with the winding mechanism 500. The second pawl 1210 is disposed on the handle 700. The second pawl 1210 can engage with or disengage from the second ratchet 1220. Exemplarily, when the second pawl 1210 is engaged with the second ratchet 1220, the handle 700 can drive the winding mechanism 500 to rotate in a first clockwise direction. When the second pawl 1210 is disengaged from the second ratchet 1220, the handle 700 can rotate relative to the winding mechanism 500 in a second clockwise direction.

[0068] In some optional embodiments, the connection method between the handle 700 and the reeling mechanism 500 may also adopt the same connection structure as the handle and reeling mechanism in the existing cable tensioner.

[0069] In some optional embodiments, the energy storage mechanism 300 further includes a locking member 340 and a second elastic member 350. The locking member 340 is arranged on the trajectory of the linkage rod 320 moving relative to the shell 100, and the locking member 340 is located on the trajectory of the handle 700 rotating relative to the shell 100. One end of the second elastic member 350 is connected to the linkage rod 320, and the other end is connected to the shell 100, and the second elastic member 350 can push the linkage rod 320 to move away from the winding mechanism 500. When the linkage rod 320 acts on the winding mechanism 500 to switch to the first state, the linkage rod 320 is limited by the locking member 340 and the shell 100, and the locking member 340 can be released from the limited cooperation with the linkage rod 320 under the action of the handle 700. Optionally, during the process of the handle 700 rotating relative to the shell 100 in the second clockwise direction, it can stop at the locking member 340 and trigger the locking member 340 to unlock with the linkage rod 320. Reference Figure 11 A third limit block 130 is provided on the shell 100, and at least a portion of the third limit block 130 is located in the cavity of the linkage rod 320 where the second elastic member 350 is installed, and the third limit block 130 stops at one end of the second elastic member 350.

[0070] The above embodiment can limit the linkage rod 320 through the locking member 340, thereby facilitating the action of the linkage rod 320 on the reeling mechanism 500, allowing the reeling mechanism 500 to remain in the second state continuously, thereby providing sufficient time for the energy storage mechanism 300 to release energy. Furthermore, after the energy storage mechanism 300 has completely released energy, the locking member 340 can be unlocked by shaking the handle 700, thereby allowing the linkage rod 320 to move away from the reeling mechanism 500 under the action of the second elastic member 350, thereby ensuring that the reeling mechanism 500 can switch from the second state to the first state.

[0071] In the above embodiment of the power construction tightening device, the operator only needs to operate the handle 700 to switch the winding mechanism 500 from the second state to the first state, thereby simplifying the operation difficulty of the power construction tightening device.

[0072] In some embodiments, the handle 700 can rotate unidirectionally relative to the winding mechanism 500. Specifically, when the handle 700 rotates in a first clockwise direction relative to the housing 100, the handle 700 can drive the winding mechanism 500 to rotate in the first clockwise direction. When the handle 700 rotates in a second clockwise direction relative to the housing 100, the handle 700 rotates in the second clockwise direction relative to the winding mechanism 500.

[0073] Reference Figure 17 and Figure 18 In some embodiments, a first limit block 110 and a second limit block 120 are provided on the housing 100. The first limit block 110 and the second limit block 120 are provided on the path of the handle 700 rotating relative to the housing 100. For example, the handle 700 may stop at the first limit block 110 during the process of rotating relative to the housing 100 in a first clockwise direction. The handle 700 may stop at the second limit block 120 during the process of rotating relative to the housing 100 in a second clockwise direction. This embodiment can limit the movement range of the handle 700 by the first limit block 110 and the second limit block 120, thereby helping to prevent the handle 700 from rotating excessively.

[0074] In some embodiments, the power construction line tightening device further includes a second ratchet mechanism 1200. The handle 700 is connected to the winding mechanism 500 via the second ratchet mechanism 1200, and the handle 700 can drive the winding mechanism 500 to rotate unidirectionally in a first clockwise direction. An unlocking protrusion 140 is provided on the housing 100. The unlocking protrusion 140 is disposed on the rotation path of the second ratchet mechanism 1200. During the process of the handle 700 rotating relative to the winding mechanism 500 in the second clockwise direction, the second ratchet mechanism 1200 and the unlocking protrusion 140 abut against each other, causing the second ratchet mechanism 1200 to unlock. For example, when the first pawl 510 is disengaged from the first ratchet 530 and the second ratchet mechanism 1200 is unlocked, the winding mechanism 500 can rotate relative to the handle 700 in the second clockwise direction.

[0075] For example, during the process of the handle 700 rotating in the second clockwise direction relative to the winding mechanism 500, the second pawl 1210 in the second ratchet mechanism 1200 can move in the unlocking direction relative to the second ratchet 1220 under the action of the unlocking protrusion 140, that is, the second pawl 1210 can switch from a state of engagement with the second ratchet 1220 to a state of separation.

[0076] It should be noted that in a ratchet mechanism, the pawl is generally equipped with an elastic member, and the pawl can engage with the ratchet under the action of the elastic member. Specifically, the elastic member can be, but is not limited to, a torsion spring. Specifically, the type of elastic member can be selected according to actual needs. For example, the pawls in the ratchet structure of the power construction tensioning device described in this application are all equipped with corresponding elastic members, and the pawls can engage with the ratchet under the action of the elastic member.

[0077] In some embodiments, the primary reference Figure 23 It can be inferred that the second ratchet mechanism 1200 is first unlocked during the rotation of the handle 700 relative to the housing 100 in the second clockwise direction. After the second ratchet mechanism 1200 is first unlocked, the handle 700 can continue to rotate relative to the housing 100 in the second clockwise direction. During the rotation of the handle 700 relative to the housing 100 in the second clockwise direction, the handle 700 may abut against the locking member 340, triggering the locking member 340 to release the restraining engagement with the linkage rod 320.

[0078] Illustratively, when the handle 700 rotates relative to the housing 100 along the second clockwise direction, the second pawl 1210 provided on the handle 700 first abuts against the unlocking protrusion 140 on the housing 100 and triggers the second pawl 1210 to separate from the second ratchet 1220 .

[0079] Reference Figure 18 and Figure 19 In some embodiments, the locking member 340 includes a locking tongue 341. Exemplarily, the locking member 340 can be slidably engaged with the housing 100, and the locking member 340 can be limitedly engaged with or released from the linkage rod 320 by sliding relative to the housing 100. Exemplarily, when the locking member 340 is limitedly engaged with the linkage rod 320, the locking member 340 only restricts the linkage rod 320 from moving away from the first pawl 510. That is, when the locking member 340 is limitedly engaged with the linkage rod 320, the linkage rod 320 can still move toward the first pawl 510 under the action of the trigger member 330. When the locking member 340 is released from the limited engagement with the linkage rod 320, the locking member 340 can move away from the first pawl 510 under the action of the second elastic member 350.

[0080] The locking member 340 further includes a sixth elastic member 342. Exemplarily, the sixth elastic member 342 is connected to the housing 100 and the lock tongue 341, and the lock tongue 341 can move toward the direction close to the linkage rod 320 under the action of the sixth elastic member 342, so that the lock tongue 341 can be locked with the linkage rod 320 under the action of the sixth elastic member 342. Figure 24In some embodiments, the lock tongue 341 is slidably disposed on the second limit block 120. Specifically, a sliding groove can be provided on the second limit block 120 so that at least a portion of the lock tongue 341 can slide within the sliding groove. In some embodiments, the lock tongue 341 has an inclined surface 3411. When the handle 700 is rotated in the second clockwise direction, the handle 700 pushes against the inclined surface 3411 and slides along the inclined surface 3411, thereby causing the lock tongue 341 to move away from the linkage rod 320, thereby unlocking the lock tongue 341 from the linkage rod 320.

[0081] In some embodiments, the lock tongue 341 is provided with a lock tooth 3412 that cooperates with the linkage rod 320. Optionally, the lock tooth 3412 has a guide surface and a limiting surface. Exemplarily, the limiting surface is perpendicular to the movement direction of the linkage rod 320 approaching the first pawl 510. The guide surface is arranged at an angle relative to the movement direction of the linkage rod 320 approaching the first pawl 510. Specifically, the guide surface is provided on the side of the lock tooth 3412 adjacent to the first pawl 510, and the guide surface is provided on the side of the lock tooth 3412 away from the first pawl 510. In the process of the linkage rod 320 approaching the first pawl 510, the tooth structure on the linkage rod 320 that cooperates with the lock tooth 3412 can slide along the guide surface and pass over the lock tooth 3412. When the linkage rod 320 moves away from the first pawl 510 , the tooth structure on the linkage rod 320 that cooperates with the lock tooth 3412 stops at the limiting surface to achieve one-way limiting cooperation between the linkage rod 320 and the lock tooth 3412 , thereby preventing the linkage rod 320 from moving away from the first pawl 510 .

[0082] In some embodiments, reference Figure 3 、 Figure 4 and Figure 7 The first wire clamp 400 includes a base 410, a first clamping arm 420, a first clamping block 430 and a third elastic member. The third elastic member is not shown in the drawings. Specifically, the third elastic member can be a torsion spring. Figure 3 and Figure 7 The middle portion of the first clamping arm 420 is rotatably engaged with the base 410. One end of the first clamping arm 420 is rotatably connected to the first clamping block 430, and the other end of the first clamping arm 420 is connected to the traction rope 200. The traction rope 200 can pull the first clamping arm 420 to rotate relative to the base 410, causing the second clamp 600 to clamp and securely engage the cable 10. A third elastic member is disposed between the first clamping arm 420 and the base 410. The third elastic member can cause the first clamping arm 420 to rotate relative to the base 410, causing the first clamp 400 to slide and engage with the cable 10. The third elastic member can be, but is not limited to, a torsion spring.

[0083] In the above embodiment, the first wire clamp 400 can clamp and fix the cable 10 by pulling the traction rope 200, and the third elastic member can be used to open the first wire clamp 400 during the process of releasing energy from the energy storage mechanism 300, thereby achieving sliding cooperation between the first wire clamp 400 and the cable 10.

[0084] In some embodiments, reference Figure 3 、 Figure 4 and Figure 7 The first cable clamp 400 further includes a fourth elastic member and two first guide wheels 440 with guide slots 441. The first guide wheels 440 are rotatably mounted on the base 410. At least one of the two first guide wheels 440 is movable relative to the base 410 and connected to the base 410 via a fourth elastic member. This allows the two first guide wheels 440 to approach each other and clamp the cable 10 under the action of the fourth elastic member. Exemplarily, the first guide wheels 440 are rotatably coupled to the base 410 via a mounting arm. Specifically, the first guide wheel 440 is mounted at a first end of the mounting arm, and the second end of the mounting arm is rotatably coupled to the base 410. In some embodiments, a fourth elastic member may be mounted on the mounting arm and connected to the base 410, so that the fourth elastic member can drive the mounting arm to rotate relative to the base 410, causing the two first guide wheels 440 to approach each other and abut against each other. Specifically, when the two first guide wheels 440 approach each other and abut against each other, the guide slots 441 on the two first guide wheels 440 can enclose and form a passage for the cable 10.

[0085] In the above embodiment, the two first guide wheels 440 can be clamped on the cable 10, so that the first clamp 400 can slide along the cable 10 during the process of releasing energy from the energy storage mechanism 300. When the reeling mechanism 500 reels the traction rope 200, the two first guide wheels 440 can guide the cable 10.

[0086] Reference Figure 5 、 Figure 8 、 Figures 9 to 15 The second wire clamp 600 further includes a fifth elastic member and two second guide wheels 630 having guide grooves 441. The second guide wheels 630 are rotatably mounted on the base 410. One of the two second guide wheels 630 is movable relative to the base 410 and is connected to the base 410 via the fifth elastic member. Under the action of the fifth elastic member, the second guide wheels 630 can approach the other guide wheel and clamp the cable 10. The other guide wheel is connected to the reeling mechanism 500 and rotates with the reeling mechanism 500 as the reeling mechanism 500 reels the traction rope 200, thereby tightening the cable 10.

[0087] In the above embodiment, the winding mechanism 500 can be used to link one of the second guide wheels 630 so that the second guide wheel 630 can actively guide the cable 10, which is beneficial to avoid redundancy of the cable 10 between the first wire clamp 400 and the second wire clamp 600, and ensure that the cable 10 is in a straight line state between the first wire clamp 400 and the second wire clamp 600.

[0088] In some embodiments, the reeling mechanism 500 can be connected to one of the second guide wheels 630 via a gear transmission assembly 1100, so that rotation of the reeling mechanism 500 can drive the second guide wheel 630 to actively guide the cable 10 through the second cable clamp 600. Optionally, the reeling mechanism 500 includes a rope winding shaft 520. Specifically, the rope winding shaft 520 can be rotated relative to the housing 100 to allow the traction rope 200 to be wound and stored. In some embodiments, the reeling mechanism 500 can employ the same steel rope winding structure as cable tensioners in the prior art.

[0089] Reference Figure 23 In some embodiments, the power construction line tightening device further includes a first ratchet mechanism 1000. Optionally, the first ratchet mechanism 1000 is disposed between the rope winding shaft 520 of the reeling mechanism 500 and the gear transmission assembly 1100, such that rotation of the reeling mechanism 500 in the first clockwise direction can drive the second guide wheel 630 to rotate, thereby actively pulling the cable 10 between the first and second clamps 400 and 600. Specifically, during energy release from the energy storage mechanism 300, the reeling mechanism 500 rotates in the second clockwise direction without driving the first ratchet mechanism 1000 to rotate.

[0090] In some optional embodiments, the first ratchet mechanism 1000 can be a ratchet mechanism disposed within a gear. For example, the structure of the first ratchet mechanism 1000 can be the same as the ratchet structure between the driving wheel and the sprocket of a bicycle. For example, the first ratchet mechanism 1000 can be an internal ratchet mechanism.

[0091] In some embodiments, the power construction tensioning device further includes a tension detector 800 and a mounting structure 900. The mounting structure 900 is connected to the housing 100 via the tension detector 800, and the mounting structure 900 is used to be fixedly connected to the tower. The tension detector 800 is a device that can be used to detect rope tension in the prior art. In an optional embodiment, the tension detector 800 includes a meter for displaying the detected tension, so that the operator can determine the tension of the cable 10 based on the tension detected by the tension detector 800, thereby preventing over-tensioning or under-tensioning of the cable 10.

[0092] The mounting structure 900 may be the same as the mounting structure 900 of a cable tensioner in the prior art. For example, the mounting structure 900 may be, but is not limited to, a hook.
