Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and more particularly, to a wire tightening device for electric power construction. Background Art

[0002] During the operation of electric power engineering, workers first set up the cable on the utility pole or the transmission tower, and then tighten the cable through a wire tightener for electric power construction to reduce the sag caused by gravity, suppress the wind-induced vibration, and avoid the wear or broken strands of the fittings due to uneven distribution of the cable tension.

[0003] In the related art, during the use of the wire tightener for electric power construction, electric power workers need to first fix one end of the wire tightener for electric power construction to the utility pole or the transmission tower, release the traction steel rope of the wire tightener for electric power construction, and clamp the wire clamp connected to the end of the traction steel rope to the cable. During the process of fixing the wire clamp, it is necessary to ensure that there is a distance for the wire clamp to move between the traction steel rope and the utility pole or the transmission tower, so that the cable can be tightened when the traction steel rope is tightened.

[0004] In the actual operation process, it often happens that due to the insufficient distance reserved between the wire clamp and the utility pole or the transmission tower, when the traction steel rope is completely retracted, the cable still cannot be tightened to the desired tightness. In this case, electric power workers need to first preliminarily fix the cable, then disassemble the wire clamp, release the traction steel rope, and adjust the position of the tightening clamp for re-tightening operation. Summary of the Invention

[0005] The present invention discloses a wire tightening device for electric power construction to solve the technical problem that the wire tightener for electric power construction in the related art is prone to repeatedly fixing the cable and the tightener and manually releasing the traction steel rope repeatedly.

[0006] To solve the above problems, the present invention adopts the following technical solutions: Some embodiments of the present application provide a wire tightening device for electric power construction, including: a housing, a traction rope, an energy storage mechanism, a first wire clamp, and a winding mechanism and a second wire clamp disposed on the housing. The energy storage mechanism is disposed between the first wire clamp and the second wire clamp, and the first wire clamp is connected to the winding 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 is slidably engaged with the cable, the winding mechanism is in a first state, and can rotate unidirectionally in a first clockwise direction to drive the traction rope to be wound in 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 is slidably engaged with the cable, the second wire clamp clamps and fixes the cable, the winding mechanism switches to a second state, and the energy storage mechanism can drive the first wire clamp to move away from the second wire clamp and drive the winding mechanism to rotate in a second clockwise direction.

[0007] In some solutions, when the first distance is less than or equal to the first preset value, the first wire clamp and / or the energy storage mechanism can act on the winding mechanism, causing the winding mechanism to switch from the first state to the second state.

[0008] The technical solution adopted by the present invention can achieve the following beneficial effects: In the wire tightening device for electric power construction provided by the present application, during the process of clamping and tensioning the cable by the first wire clamp, the winding mechanism winds the traction rope, and the traction rope is used to pull the first wire clamp to drive the cable to be tensioned. At the same time, the approaching process of the first wire clamp and the second wire clamp will compress the energy storage mechanism, so that the energy storage mechanism stores energy. Specifically, the winding mechanism can only rotate unidirectionally in the first state to avoid the release of the energy of the energy storage mechanism. When the first wire clamp approaches the second wire clamp to a preset distance, it will trigger the winding mechanism to switch to the second state. After the winding mechanism switches to the second state, the winding mechanism can already rotate bidirectionally. 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 away from the second wire clamp. During this process, the traction rope wound by the winding mechanism is also released.

[0009] Moreover, during the process of the energy storage mechanism releasing energy, the second wire clamp and the cable are already in a state of clamping and fixing, so the cable can be prevented from loosening, and the first wire clamp moves along the cable away from the second wire clamp. After the energy released by the energy storage structure is released, the traction rope can be wound again by the winding mechanism, and the above steps can be repeated. During the whole process, the operator only needs to operate the winding mechanism to keep the winding action, thus avoiding the pulling stroke of the traction rope from restricting the tensioning movement distance of the cable and disassembling and assembling the cable and the wire tightening device for electric power construction multiple times. And, the wire tightening device for electric power construction provided this time can automatically release the traction rope under the action of the energy storage mechanism during the cable tensioning process, without manual operation of its release, which is beneficial to simplifying the cable operation steps and improving the cable tensioning efficiency.

Detailed implementation manners

[0013] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope protected by the present invention.

[0014] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0015] The following combines the attached Figures 1 to 24 , and through specific embodiments and their application scenarios, the power construction wire tensioning device provided by the embodiments of this application will be described in detail.

[0016] Refer to Figure 1 and Figure 11 , this application provides a power construction wire tensioning device. The power construction wire tensioning device includes a housing 100, a traction rope 200, an energy storage mechanism 300, a first wire clamp 400, and a winding mechanism 500 and a second wire clamp 600 provided on the housing 100. Among them, the housing 100 is a basic structural member that can provide an installation basis for other components. Exemplarily, the traction rope 200 can be, but is not limited to, a steel rope, a nylon rope, or a strip rope.

[0017] Refer to Figure 1 , the energy storage mechanism 300 is arranged 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 through the traction rope 200. Optionally, the energy storage mechanism 300 can be, but is not limited to, an elastic energy storage mechanism.

[0018] Refer to Figures 2 to 5, the distance between the first wire clamp 400 and the second wire clamp 600 is the first distance. When the first distance is greater than the first preset value, the first wire clamp 400 clamps and fixes the wire 10. The second wire clamp 600 is in sliding fit with the wire 10. Exemplarily, both the first wire clamp 400 and the second wire clamp 600 have wire grooves for accommodating the wire 10. Exemplarily, the fixing or sliding fit between the first wire clamp 400 and the wire 10 can be achieved by adjusting the opening degree of the first wire clamp 400. The fixing or sliding fit between the second wire clamp 600 and the wire 10 can be achieved by adjusting the opening degree of the second wire clamp 600. The winding mechanism 500 is in the first state and can rotate unidirectionally along the first clockwise direction to drive the traction rope 200 to wind inside the housing 100, so that the first wire clamp 400 approaches the second wire clamp 600 and stores energy for the energy storage mechanism 300. Exemplarily, the winding mechanism 500 is provided with a ratchet structure, and the unidirectional rotation of the winding mechanism 500 can be achieved through the ratchet mechanism. Specifically, when the winding mechanism 500 is in the first state, the pawl of the ratchet mechanism meshes with the ratchet to enable the winding mechanism 500 to only rotate along the first clockwise direction. The first clockwise direction can be the clockwise direction or the counterclockwise direction. Specifically, it is subject to the winding of the traction rope 200 around the winding mechanism 500. In some embodiments, when the first clockwise direction is the clockwise direction, the second clockwise direction is the counterclockwise direction. In some embodiments, when the first clockwise direction is the counterclockwise direction, the second clockwise direction is the clockwise direction.

[0019] It should be noted that the first preset value can be set as needed. Specifically, those skilled in the art can set the size of the first preset value according to the range of motion of the operator's arm movement to facilitate the operator to install the power construction wire tightening device. Specifically, based on ergonomics, the size of the first preset value can be designed in combination with the lengths of the arms of most adults. Therefore, the embodiments of the present application do not describe the size of the first preset value in detail.

[0020] In some embodiments, the structure of the winding mechanism 500 can be the same as the mechanism for winding the steel wire in the existing power construction wire tightening device.

[0021] Mainly refer to Figures 6 to 9It can be inferred that when the first distance is less than or equal to the first preset value, the first wire clamp 400 is in sliding fit 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 away from the second wire clamp 600 and drive the winding mechanism 500 to rotate in 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 one-way rotation of the winding mechanism 500 is separated from the ratchet, so that the rotation of the ratchet is no longer restricted by the pawl, and thus the winding mechanism 500 can rotate in the direction of releasing the towing rope 200.

[0022] In some embodiments, the first wire clamp 400 and the second wire clamp 600 can adopt a linkage wire clamping structure to open or clamp the first wire clamp 400 and the second wire clamp 600 through the direction of the acting force of the cable 10 on the first wire clamp 400 or the second wire clamp 600. Exemplarily, the first wire clamp 400 or the second wire clamp 600 can adopt a clamping mechanism for clamping and fixing the cable 10 in the existing power construction wire tightening device.

[0023] Referring to Figure 1 、 Figure 2 and Figure 6 In the above-mentioned power construction wire tightening device provided in the above embodiments, during the process of tightening the cable 10, the operator operates the winding mechanism 500 to rotate in the first clockwise direction, so that the towing rope 200 is wound around the winding mechanism 500, and then the first wire clamp 400 is pulled closer to the second wire clamp 600. Referring to Figure 3 Due to the pulling of the towing rope 200, the first wire clamp 400 will clamp and fix the cable 10. Further, during the process of the winding mechanism 500 winding the cable 10, the cable 10 is pulled closer from the first wire clamp 400 to the second wire clamp 600, so that the acting force of the cable 10 on the second wire clamp 600 makes the second wire clamp 600 tend to open, and thus the sliding fit between the cable 10 and the second wire clamp 600 is realized.

[0024] When the first distance is less than or equal to the first preset value, the second wire clamp 600 clamps and fixes the cable 10, which is beneficial to preventing the cable 10 from sliding under the action of gravity. In some embodiments, the cable 10 can drive the second wire clamp 600 to clamp and fix the cable 10 by sliding relative to the second wire clamp 600 under the action of gravity. In addition, the one-way rotation of the winding mechanism 500 is released, and the energy storage mechanism 300 releases energy, and then the first wire clamp 400 can be pushed to move away from the second wire clamp 600. Exemplarily, the energy released by the energy storage mechanism 300 acts on the first wire clamp 400, and the first wire clamp 400 is opened by using the frictional force between the first wire clamp 400 and the cable 10. After the energy storage mechanism 300 finishes releasing energy, the first distance is greater than the first preset value, and then the above steps can be repeated.

[0025] Therefore, the power construction wire tightening device provided by the above embodiments can avoid the operator from repeatedly disassembling and releasing the traction rope 200, which is beneficial to simplifying the operation of the operator and improving the efficiency of the cable 10 tensioning operation. In addition, during the installation of the power construction wire tightening device, the traction rope 200 can be wound first, and it is ensured that the first distance is greater than the preset value. Specifically, when the operator installs the first wire clamp 400 for the first time, the distance between the position where the first wire clamp 400 cooperates with the cable 10 and the tower line is the second distance. The above embodiments are also beneficial to reducing the second distance, thereby preventing the operator from deviating too far from the tower, reducing the installation difficulty of the power construction wire tightening device, and being beneficial to ensuring the safety during the installation of the power construction wire tightening device.

[0026] In some embodiments, when the first distance is less than or equal to the first preset value, the first wire clamp 400 and / or the energy storage mechanism 300 can act on the winding mechanism 500, causing the winding mechanism 500 to switch from the first state to the second state. When the first distance is less than or equal to the first preset value, at least part of the first wire clamp 400 and / or the energy storage mechanism 300 can abut against the winding mechanism 500 to trigger the winding mechanism 500 to switch from the first state to the second state. Exemplarily, when the first distance 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 the pawl that restricts the one-way rotation of the winding mechanism 500, so that the pawl that restricts the one-way rotation of the winding mechanism 500 is separated from its corresponding ratchet wheel, and then the winding mechanism 500 is switched from the first state to the second state.

[0027] In some embodiments, the operator can manually adjust the winding mechanism 500 so that the winding mechanism 500 can be switched between the first state and the second state. It should be noted that the mechanism for winding the steel rope in the existing cable tightener can be manually adjusted to switch between two states to realize the winding and release of the steel rope.

[0028] In some embodiments, reference 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 the first state, the first pawl 510 cooperates with the first ratchet 530 and restricts the rope winding shaft 520 from rotating in the second clockwise direction. When the winding mechanism 500 is in the second state, the first pawl 510 is separated from the first ratchet 530. When the first spacing is less than or equal to the first preset value, the first wire clamp 400 and / or the energy storage mechanism 300 stops at the first pawl 510 to separate the first pawl 510 from the first ratchet 530, so that the first ratchet 530 and the rope winding shaft 520 can rotate relative to the housing 100 in the second clockwise direction.

[0029] In some embodiments, reference 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 the linkage rod 320 can switch between a first position and a second position relative to the housing 100. The winding mechanism 500 is transmission-connected to the linkage rod 320. When the linkage rod 320 moves to the first position, the linkage rod 320 can act on the winding mechanism 500 to switch to the second state.

[0030] In some embodiments, the second wire clamp 600 is transmission-connected to the linkage rod 320. When the linkage rod 320 moves to the first position, the linkage rod 320 can act on the second wire clamp 600 to clamp and fix the cable 10.

[0031] In some embodiments, the second wire clamp 600 and the winding mechanism 500 are both connected to the linkage rod 320, so that the linkage rod 320 can synchronously act on the winding mechanism 500 and the second wire clamp 600 to achieve synchronous adjustment of the states of the winding mechanism 500 and the second wire clamp 600. This solution is beneficial to reduce the displacement of the cable 10 sliding relative to the second wire clamp 600 during the state switching process of the winding mechanism 500. In some embodiments, the linkage rod 320 first acts on the second wire clamp 600 to clamp and fix the cable 10, and then acts on the winding mechanism 500 to switch from the first state to the second state.

[0032] 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.

[0033] In some embodiments, the second wire clamp 600 is transmission-connected to 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 cooperation with the cable 10.

[0034] ReferenceFigure 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. As Figure 21 shown, the first pawl 510 of the winding mechanism 500 is located on the trajectory of the relative movement of the column 322 with respect to the housing 100. Exemplarily, during the process that the triggering member 330 drives the linkage rod 320 to move towards 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 wheel 530, so as to realize the switching of the winding mechanism 500 from the second state to the first state. Exemplarily, when the first pawl 510 is separated from the first ratchet wheel 530 under the action of the linkage rod 320, the distance between the first wire clamp 400 and the second wire clamp 600 is equal to the size of the first preset value.

[0035] In some embodiments, Figures 11 to 16 the energy storage mechanism 300 further includes a first elastic member 310 and a triggering 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 helical spring. Preferably, the first elastic member 310 is sleeved on the towing rope 200 to guide the elastic deformation of the first elastic member 310 through the towing rope 200, thereby improving the reliability of the first elastic member 310.

[0036] When the first distance is less than or equal to the first preset value, one end of the triggering member 330 abuts against the first wire clamp 400, and the other end abuts against the linkage rod 320.

[0037] In some embodiments, referring to Figure 18 and Figure 11 the triggering member 330 is in sliding fit with the housing 100 and the towing rope 200. Exemplarily, the first end of the triggering member 330 is in sliding fit with the housing 100, and the second end points to the first wire clamp 400. Optionally, when the first distance is greater than the first preset value, the second end of the triggering member 330 is spaced from the first wire clamp 400. Exemplarily, as Figure 16 shown, the triggering member 330 may be a cylindrical structure, and the first elastic member 310 is disposed inside the triggering member 330. Further optionally, the first end of the triggering member 330 has a pushing block, and the triggering member 330 abuts against the linkage rod 320 through the pushing block.

[0038] In some embodiments, referring to Figure 12 and Figure 15As shown, the linkage rod 320 has an installation 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. The extending direction of the other end of the second clamping arm 610 is inclined relative to the moving direction of the linkage rod 320, and at least a part thereof is located in the installation groove 321. The middle part of the second clamping arm 610 is rotatably matched with the housing 100. During the energy storage process of the energy storage mechanism 300, the linkage rod 320 moves in the first direction, and the linkage rod 320 can drive the second clamping arm 610 to rotate in the first clockwise direction through the groove wall on the first side of the installation groove 321, so as to drive the second clamping block 620 to clamp and fix the cable 10. During the process of the linkage rod 320 moving in the second direction, the linkage rod 320 can drive the second clamping arm 610 to rotate in 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. The first direction is opposite to the second direction.

[0039] In the above embodiment, the linkage rod 320 can actively drive the second wire clamp 600 to clamp the cable 10 through the installation groove 321, and can also drive the second wire clamp 600 to open through the groove wall of the installation groove 321, so that the second wire clamp 600 is in sliding cooperation with the cable 10.

[0040] In some embodiments, the second wire clamp 600 is further provided with a torsion spring to drive the second wire clamp 600 to open through the torsion spring. Exemplarily, the torsion spring can be connected between the second clamping arm 610 and the housing 100, so as to drive the second clamping arm 610 to rotate relative to the housing 100 in the second clockwise direction through the torsion spring.

[0041] In some embodiments, the electric power construction wire tightening device further includes a handle 700. Refer to 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.

[0042] Exemplarily, the second ratchet mechanism 1200 includes a second pawl 1210 and a second ratchet 1220. The second ratchet 1220 is arranged on the winding mechanism 500. Specifically, the second ratchet 1220 is fixedly arranged on the winding mechanism 500 and is coaxially arranged with the winding mechanism 500. The second pawl 1210 is arranged on the handle 700. The second pawl 1210 can be engaged with or separated 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 the first clockwise direction. When the second pawl 1210 is separated from the second ratchet 1220, the handle 700 can rotate relative to the winding mechanism 500 in the second clockwise direction.

[0043] In some alternative embodiments, the connection manner between the handle 700 and the winding mechanism 500 may also adopt the same connection structure between the handle and the winding mechanism in an existing cable tensioner.

[0044] In some alternative embodiments, the energy storage mechanism 300 further includes a locking member 340 and a second elastic member 350. The locking member 340 is disposed on the trajectory of the linkage rod 320 moving relative to the housing 100, and the locking member 340 is located on the trajectory of the handle 700 rotating relative to the housing 100. One end of the second elastic member 350 is connected to the linkage rod 320, and the other end is connected to the housing 100, and the second elastic member 350 can push the linkage rod 320 to move away from the winding mechanism 500. When the winding mechanism 500 is switched to the first state under the action of the linkage rod 320, the linkage rod 320 is in limit cooperation with the housing 100 through the locking member 340, and the locking member 340 can be disengaged from the limit 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 housing 100 in the second clockwise direction, it can abut against the locking member 340 and trigger the unlocking of the locking member 340 and the linkage rod 320. Refer to Figure 11 , a third limiting block 130 is provided on the housing 100, at least a part of the third limiting block 130 is located in the cavity of the linkage rod 320 where the second elastic member 350 is installed, and the third limiting block 130 abuts against one end of the second elastic member 350.

[0045] The above embodiments can limit the linkage rod 320 through the locking member 340, which is beneficial to act on the winding mechanism 500 through the linkage rod 320, so that the winding mechanism 500 can continuously maintain the second state, thereby providing enough time for the energy release of the energy storage mechanism 300. Further, after the energy release of the energy storage mechanism 300 is completed, the handle 700 can be shaken to trigger the unlocking of the locking member 340 by the handle 700, so that the linkage rod 320 can move away from the winding mechanism 500 under the action of the second elastic member 350, thereby ensuring that the winding mechanism 500 can be switched from the second state to the first state.

[0046] For the power construction wire tightening device in the above embodiments, the operator only needs to operate the handle 700 to realize the switching of the winding mechanism 500 from the second state to the first state, which is beneficial to simplify the operation difficulty of the power construction wire tightening device.

[0047] In some embodiments, the handle 700 can rotate unidirectionally relative to the winding mechanism 500. Specifically, during the process of the handle 700 rotating relative to the housing 100 in the first clockwise direction, the handle 700 can drive the winding mechanism 500 to rotate in the first clockwise direction. During the process of the handle 700 rotating relative to the housing 100 in the second clockwise direction, the handle 700 rotates relative to the winding mechanism 500 in the second clockwise direction.

[0048] Reference Figure 17 and Figure 18 In some embodiments, a first limiting block 110 and a second limiting block 120 are provided on the housing 100. The first limiting block 110 and the second limiting block 120 are arranged on the path of the handle 700 rotating relative to the housing 100. Exemplarily, during the process of the handle 700 rotating relative to the housing 100 in the first clockwise direction, it can abut against the first limiting block 110. During the process of the handle 700 rotating relative to the housing 100 in the second clockwise direction, it can abut against the second limiting block 120. This embodiment can limit the moving range of the handle 700 through the first limiting block 110 and the second limiting block 120, thereby being beneficial to preventing the handle 700 from rotating excessively.

[0049] In some embodiments, the electric power construction wire tightening device further includes a second ratchet mechanism 1200. The handle 700 is connected to the winding mechanism 500 through the second ratchet mechanism 1200, and the handle 700 can drive the winding mechanism 500 to rotate unidirectionally in the first clockwise direction. An unlocking protrusion 140 is provided on the housing 100. The unlocking protrusion 140 is arranged on the path of the second ratchet mechanism 1200 rotating. During the process of the handle 700 rotating relative to the winding mechanism 500 in the second clockwise direction, the second ratchet mechanism 1200 abuts against the unlocking protrusion 140, causing the second ratchet mechanism 1200 to be unlocked. Exemplarily, when the first pawl 510 is separated 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.

[0050] Exemplarily, during the process of the handle 700 rotating relative to the winding mechanism 500 in the second clockwise direction, the second pawl 1210 in the second ratchet mechanism 1200 can move relative to the second ratchet 1220 in the unlocking direction under the action of the unlocking protrusion 140, that is, the second pawl 1210 can be switched from the meshing state with the second ratchet 1220 to the separated state.

[0051] It should be noted that in a ratchet mechanism, a pawl is generally configured with an elastic member, and the pawl can be meshed 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 the elastic member can be selected according to actual needs. Exemplarily, the pawls in the ratchet structure of the electric power construction wire tightening device described in the present application are all provided with corresponding elastic members, and can all be meshed with the ratchet under the action of the elastic members.

[0052] In some embodiments, mainly referring to Figure 23It can be inferred that during the process of the handle 700 rotating relative to the housing 100 in the second clockwise direction, the second ratchet mechanism 1200 is unlocked first. After the second ratchet mechanism 1200 is unlocked first, the handle 700 can continue to rotate relative to the housing 100 in the second clockwise direction, and during the process of the handle 700 continuing to rotate relative to the housing 100 in the second clockwise direction, the handle 700 can abut against the locking member 340 and trigger the locking member 340 to release the limit cooperation with the linkage rod 320.

[0053] Exemplarily, during the process of the handle 700 rotating relative to the housing 100 in the second clockwise direction, the second pawl 1210 provided on the handle 700 first abuts against the unlocking lug 140 on the housing 100 and triggers the separation of the second pawl 1210 from the second ratchet 1220.

[0054] Refer to 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 in limit cooperation or release limit cooperation with the linkage rod 320 by sliding relative to the housing 100. Exemplarily, when the locking member 340 is in limit cooperation with the linkage rod 320, the locking member 340 only restricts the movement of the linkage rod 320 in the direction away from the first pawl 510. That is to say, when the locking member 340 is in limit cooperation with the linkage rod 320, the linkage rod 320 can still move in the direction close to the first pawl 510 under the action of the triggering member 330. When the locking member 340 is released from the limit cooperation with the linkage rod 320, the locking member 340 can move in the direction away from the first pawl 510 under the action of the second elastic member 350.

[0055] The locking member 340 further includes a sixth elastic member 342. Exemplarily, the sixth elastic member 342 is respectively connected to the housing 100 and the locking tongue 341, and the locking tongue 341 can move in the direction close to the linkage rod 320 under the action of the sixth elastic member 342, so that the locking tongue 341 can be locked with the linkage rod 320 under the action of the sixth elastic member 342. Refer to Figure 24 In some embodiments, the locking tongue 341 is slidably disposed on the second limiting block 120. Specifically, a chute can be provided on the second limiting block 120 so that at least a part of the locking tongue 341 can slide in the chute. In some solutions, the locking tongue 341 has an inclined surface 3411. During the process of the handle 700 rotating in the second clockwise direction, the handle 700 abuts against the inclined surface 3411 and slides along the inclined surface 3411, thereby causing the locking tongue 341 to move in the direction away from the linkage rod 320 to realize the unlocking of the locking tongue 341 and the linkage rod 320.

[0056] In some embodiments, the locking tongue 341 is provided with locking teeth 3412 that cooperate with the linkage rod 320. Optionally, the locking teeth 3412 have a guiding surface and a limiting surface. Exemplarily, the limiting surface is perpendicular to the moving direction of the linkage rod 320 approaching the first pawl 510. The guiding surface is inclined with respect to the moving direction of the linkage rod 320 approaching the first pawl 510. Specifically, the guiding surface is provided on the side of the locking teeth 3412 adjacent to the first pawl 510, and the guiding surface is provided on the side of the locking teeth 3412 away from the first pawl 510. During the process of the linkage rod 320 approaching the first pawl 510, the tooth structure on the linkage rod 320 that cooperates with the locking teeth 3412 can slide along the guiding surface and pass over the locking teeth 3412. During the process of the linkage rod 320 moving away from the first pawl 510, the tooth structure on the linkage rod 320 that cooperates with the locking teeth 3412 abuts against the limiting surface to achieve one-way limiting cooperation between the linkage rod 320 and the locking teeth 3412, thereby preventing the linkage rod 320 from moving away from the first pawl 510.

[0057] In some embodiments, referring to Figure 3 , Figure 4 and Figure 7 , the first wire clamp 400 includes a seat body 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. Referring to Figure 3 and Figure 7 , the middle of the first clamping arm 420 is rotatably engaged with the seat body 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 seat body 410, causing the second wire clamp 600 to clamp and fix the cable 10. The third elastic member is disposed between the first clamping arm 420 and the seat body 410, and the third elastic member can act on the first clamping arm 420 to rotate relative to the seat body 410, causing the first wire clamp 400 to be slidably engaged with the cable 10. The third elastic member can be, but is not limited to, a torsion spring.

[0058] In the above embodiments, the first wire clamp 400 can clamp and fix the cable 10 by pulling the traction rope 200, and during the process of the energy storage mechanism 300 releasing energy, the third elastic member can be used to open the first wire clamp 400, thereby achieving the sliding cooperation between the first wire clamp 400 and the cable 10.

[0059] In some embodiments, referring to Figure 3 , Figure 4 and Figure 7, the first wire clamp 400 further includes a fourth elastic member and two first guide wheels 440 having guide grooves 441. The first guide wheels 440 are rotatably disposed on the seat body 410. Among the two first guide wheels 440, at least one is movable relative to the seat body 410 and is connected to the seat body 410 through the fourth elastic member, so that the two first guide wheels 440 can approach each other and clamp the cable 10 under the action of the fourth elastic member. Exemplarily, the first guide wheel 440 is rotatably connected to the seat body 410 through a mounting arm. Specifically, the first guide wheel 440 is disposed at the first end of the mounting arm, and the second end of the mounting arm is rotatably connected to the seat body 410. In some embodiments, the fourth elastic member can be disposed on the mounting arm and connected to the seat body 410, so that the fourth elastic member can drive the mounting arm to rotate relative to the seat body 410 and make the two first guide wheels 440 approach each other and abut. Specifically, when the two first guide wheels 440 approach each other and abut, the guide grooves 441 on the two first guide wheels 440 can enclose a channel for passing through the cable 10.

[0060] In the above embodiments, the two first guide wheels 440 can be clamped on the cable 10, so that the first wire clamp 400 can slide along the cable 10 during the process of the energy storage mechanism 300 releasing energy. During the process of the winding mechanism 500 winding the traction rope 200, the two first guide wheels 440 can play a guiding role for the cable 10.

[0061] Referring to 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 disposed on the seat body 410. Among the two second guide wheels 630, one is movable relative to the seat body 410 and is connected to the seat body 410 through the fifth elastic member, and can approach the other and clamp the cable 10 under the action of the fifth elastic member. The other is connected to the winding mechanism 500 and rotates with the winding mechanism 500 during the process of the winding mechanism 500 winding the traction rope 200, driving the cable 10 to be tensioned.

[0062] In the above embodiments, 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 avoiding redundancy of the cable 10 between the first wire clamp 400 and the second wire clamp 600 and ensuring that the cable 10 between the first wire clamp 400 and the second wire clamp 600 is in a straight state.

[0063] In some embodiments, the rewinding mechanism 500 can be drivingly connected to one of the second guide wheels 630 through a gear transmission group 1100, so that the second guide wheel 630 can be actively guided to lead the cable 10 through the second cable clamp 600 during the rotation of the rewinding mechanism 500. Optionally, the rewinding mechanism 500 includes a rope winding shaft 520. Specifically, the traction rope 200 can be stored in a winding manner by rotating the rope winding shaft 520 relative to the housing 100. In some embodiments, the rewinding mechanism 500 can adopt the same structure for winding steel ropes as that of the cable tensioner in the prior art.

[0064] Referring to Figure 23 , in some embodiments, the electric power construction cable tensioning device further includes a first ratchet mechanism 1000. Optionally, the first ratchet mechanism 1000 is disposed between the rope winding shaft 520 of the rewinding mechanism 500 and the gear transmission group 1100, so that the second guide wheel 630 can be driven to rotate during the rotation of the rewinding mechanism 500 in the first clockwise direction to actively draw the cable 10 between the first cable clamp 400 and the second cable clamp 600. Specifically, during the energy release process of the energy storage mechanism 300, the rewinding mechanism 500 rotates in the second clockwise direction and does not drive the first ratchet mechanism 1000 to rotate.

[0065] In some alternative embodiments, the first ratchet mechanism 1000 can be a ratchet mechanism disposed inside the gear. Exemplarily, 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. Exemplarily, the first ratchet mechanism 1000 can be an internal ratchet mechanism.

[0066] In some embodiments, the electric power construction cable tensioning device further includes a tension detector 800 and a mounting structure 900. The mounting structure 900 is connected to the housing 100 through the tension detector 800, and the mounting structure 900 is used to be fixedly connected to a line tower. The tension detector 800 is a device that can be used to detect the tension of a rope in the prior art. In an alternative embodiment, the tension detector 800 includes an instrument for displaying the detected tension, so that an operator can judge the tension degree of the cable 10 according to the tension detected by the tension detector 800 to avoid excessive tension or insufficient tension of the cable 10.

[0067] The mounting structure 900 can be the same as the mounting structure 900 of the cable tensioner in the prior art. Exemplarily, the mounting structure 900 can be, but is not limited to, a hook.
