Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power transmission line tools, and particularly relates to a power transmission line slackness adjusting device and a use method. BACKGROUND

[0002] The power transmission line is a very important part in the power system, which is responsible for transmitting the power generated by the power plant to the user end. The power transmission line is used to realize the power transmission by using the transformer to step up the power generated by the generator and then connecting the power transmission line through the circuit breaker and other control devices. The power transmission line is usually composed of metal wires (such as aluminum alloy, copper, etc.), and is erected in a single loop or double loop manner. The wires are connected to the iron tower through insulators, and the iron tower is fixed on the ground, playing a key role in power transmission. Since the overhead power transmission line is erected in the air, the suspended part of the cable will sag under the action of gravity. In addition, since the power transmission line is erected in the outdoor environment for a long time, the thermal expansion and cold contraction caused by temperature change are particularly obvious. The relatively loose power transmission line is easily damaged by factors such as strong wind, thunderstorm, hail, icing and other bad weather, and is easily shaken. In addition, in the case of too tight state, the cable is easily broken by factors such as accumulated snow and icing, which not only exists a great safety hazard, but also causes economic loss. The existing adjusting device generally only supports single-direction cable line adjusting operation, and cannot adaptively adjust according to the direction of the cable line, resulting in poor practicability and actual use effect. In addition, the existing adjusting device generally adopts a fixed structure, which is only suitable for single or fixed interval cable line adjustment, that is, the adjusting device cannot be adjusted according to the actual interval distance of the cable line, resulting in that the adjusting device cannot realize the slackness adjustment of the cable line with multiple intervals. Therefore, it is necessary to provide a power transmission line slackness adjusting device and a use method, which has simple and reasonable structure, is suitable for multiple-direction cable lines, is suitable for multiple-interval cable lines, has good use effect and high practicability. SUMMARY

[0003] The present application belongs to the technical field of power transmission line tools, and particularly relates to a power transmission line slackness adjusting device and a use method.

[0004] The objective of this invention is achieved as follows: Firstly, a transmission line slack adjustment device includes a base and a tension fine-tuning assembly. The upper surface of the base is evenly spaced with multiple horizontal grooves from left to right. Each horizontal groove contains a horizontal longitudinal groove, and each longitudinal groove contains a tension fine-tuning assembly. The lower end of each tension fine-tuning assembly extends into the base, and the lower end of each assembly is connected to a two-axis degree-of-freedom adjustment mechanism. The lower ends of the two-axis degree-of-freedom adjustment mechanisms are movably connected to the inner wall of the base via movable seats. The two-axis degree-of-freedom adjustment mechanisms drive the tension fine-tuning assembly to move within the horizontal grooves and longitudinal grooves, thereby achieving adjustment of the tension fine-tuning assembly along the horizontal x-axis and y-axis. Slide plates are connected between the two-axis degree-of-freedom adjustment mechanisms. The upper and lower ends of each slide plate are slidably connected to corresponding slide rails, and a clearance cavity is provided between the slide plates.

[0005] The tension adjustment component includes a frustum. The frustum is connected to a two-axis degree-of-freedom adjustment mechanism via a rotating column. A housing is provided in the middle of the upper surface of the frustum. Several support columns are evenly spaced on the outer periphery of the lower part of the housing. Each pair of support columns has an inverted "U"-shaped clearance groove. A lifting block is provided inside the clearance groove. A screw is installed on the top surface of the lifting block. The screw extends upward through the housing and is connected to the housing through a threaded sleeve. A driver is powered to the top of the screw.

[0006] Each of the lifting blocks has a hinge seat installed at the corresponding clearance groove on its outer periphery. A connecting rod is connected to the hinge seat. The upper end of the connecting rod is movably connected to the hinge seat through a shaft pin, and the lower end is movably connected to a winding plate.

[0007] The winding plate includes an adjusting rod, which is slidably connected to a guide frame located on the upper surface of the circular platform. The inner end of the adjusting rod is provided with a U-shaped groove that is movably connected to a connecting rod. The U-shaped groove is provided with through holes. The outer end of the adjusting rod passing through the guide frame is provided with a U-shaped wire clamping plate that rotates 90° counterclockwise. The wire clamping plate is provided with a limit plate longitudinally inside.

[0008] The two-axis degree-of-freedom adjustment mechanism includes a set of symmetrically arranged fixed plates. Each fixed plate has a track on its inner side, and a slide block is slidably installed on each track. Each slide block has a telescopic outer square column installed on its inner side, and a telescopic inner square column is provided inside each telescopic outer square column. The two ends of the telescopic inner square column are respectively embedded and slidably installed with the telescopic outer square column. The telescopic outer square column is locked to the telescopic inner square column by an automatic positioner.

[0009] The telescopic embedded square column has sinking grooves on both its upper and lower surfaces. A movable block is fitted around the telescopic embedded square column. The movable block is connected to the rotating column on its upper surface. The upper and lower sides of the movable block are connected to the sinking grooves via movable wheels. A counterweight is provided at the bottom of the movable block. A main controller is provided on the left side of the counterweight. Stabilizing rods connected to the movable base are provided on both the front and rear sides of the counterweight.

[0010] A transmission line slack adjustment device further includes a quick-adjustment assembly, which is located between two fine-tuning assemblies. The quick-adjustment assembly includes a chassis located on the upper surface of a base, a guide wheel assembly mounted on the chassis, and a steering assembly between the chassis and the guide wheel assembly. The steering assembly drives the guide wheel assembly to move, thereby adjusting its direction. A set of positioning posts is provided on the upper surface of the chassis, and a set of locking holes is provided inside the positioning posts. Each locking hole is provided with a lifting locking rod.

[0011] The guide wheel assembly includes a base plate, on the upper surface of which a set of horizontal rails are symmetrically arranged. Each horizontal rail is slidably mounted with a rail seat, and each rail seat is mounted with an adjusting guide wheel.

[0012] The steering assembly includes a rotating gear disk located in the middle of the chassis. The upper surface of the rotating gear disk is connected to the lower surface of the base plate via a connecting block. A locking tongue is provided on one side of the rotating gear disk corresponding to the lifting locking rod, and an incompletely curved gear plate is provided on the other side. The steering assembly also includes a linear actuator located on one side of the upper surface of the chassis. A drive plate is installed at the output end of the linear actuator. A straight gear plate is connected to the drive plate. The straight gear plate is meshed with the incompletely curved gear plate, and the lower surface of the straight gear plate is slidably connected to the longitudinal rail.

[0013] Secondly, a method of using a transmission line slack adjustment device, which realizes slack adjustment of transmission line cables based on the transmission line slack adjustment device as described above, is characterized in that: the method of use includes the following steps: Step 1: During installation, use the base to install it at the corresponding working location. According to the design and requirements of the power transmission line, the tension adjustment component is moved in the horizontal horizontal groove and / or horizontal vertical groove by the two-axis degree of freedom adjustment mechanism, so that the position of the tension adjustment component changes, and the spacing between adjacent tension adjustment components can be adjusted according to actual needs. The tension adjustment component can also be rotated by the rotating column, thereby adjusting the direction of the winding plate. Step 2: Subsequently, according to the cable's direction, place the cable inside the corresponding winding plate. When the cable is in a slack or too tight state, the driver drives the lifting block to move up and down through the screw. The lifting block drives the adjusting rod to expand or contract relative to the guide frame through the connecting rod. The cable clamping plate drives the cable to move, thereby tightening or loosening the cable, thus making preliminary adjustments to the cable's tension and solving the problem of the cable being too slack or too tight in different seasons. Step 3: Then, according to the direction of the cable, use the steering component to adjust the guide wheel assembly of the tension quick-adjustment component to be located on the front and rear sides of the base or on the left and right sides of the base, and use the locking hole, lifting locking rod and locking tongue to achieve state locking, and place the cable inside the cable clamping plate after passing through the corresponding adjustment guide wheel. Step 4: Then the rail seat slides on the horizontal rail, which in turn drives the adjusting guide wheel to move. The adjusting guide wheel pulls a part of the cable to slide on the horizontal rail and forms a bend with the cable clamping plate, thereby tightening the cable. The cable clamping plate, together with the limiting plate, supports and limits the cable. At the same time, by adjusting the guide wheel, a part of the cable is pulled to slide in the opposite direction on the horizontal rail, reducing the degree of bending of the cable, thereby achieving cable slack adjustment.

[0014] The beneficial effects of this invention: This invention provides a transmission line slack adjustment device and its usage method. During installation, the device is mounted on a base at the corresponding work location. Based on the transmission line design and requirements, a two-axis degree-of-freedom adjustment mechanism moves the tension fine-tuning components within horizontal transverse and / or horizontal longitudinal grooves, changing their positions and thus adjusting the spacing between adjacent components according to actual needs. A rotating column can also rotate the tension fine-tuning components, adjusting the direction of the winding plate. Subsequently, based on the cable's direction, the cable is placed inside the corresponding winding plate. When the cable is in a slack or over-tight state, the driver moves the lifting block up and down via a screw. The lifting block, through a connecting rod, moves the adjusting rod outward or inward relative to the guide frame, causing the cable clamping plate to move the cable, thereby tightening or loosening the cable and initially adjusting its tension. This invention addresses the issue of cables being too loose or too tight in different seasons. Then, based on the cable's direction, the guide wheel assembly of the quick-adjustment component is adjusted using a steering assembly to position it on either the front or rear sides of the base, or on the left or right sides. Locking holes, a lifting locking rod, and a locking tongue are used to lock the cable in place. The cable passes through the corresponding adjusting guide wheel and is then placed inside the cable clamping plate. The rail base slides on the horizontal rail, moving the adjusting guide wheel and causing it to pull a portion of the cable along the horizontal rail, forming a bend with the cable clamping plate, thus tightening the cable. The cable clamping plate, in conjunction with a limiting plate, supports and limits the cable. Simultaneously, by pulling a portion of the cable along the horizontal rail in the opposite direction using the adjusting guide wheel, the degree of cable bending is reduced, thereby achieving cable slack adjustment. This invention has the advantages of simple and reasonable structure, applicability to multi-directional and multi-spacing cables, good performance, and strong practicality.

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments and / or accompanying drawings. Example 1

[0025] like Figures 1-8 As shown, a transmission line slack adjustment device includes a base 1 and a tension fine-tuning component 2. Multiple horizontal grooves 9 are evenly spaced from left to right on the upper surface of the base 1. Each horizontal groove 9 contains a horizontal vertical groove 10, and each horizontal vertical groove 10 contains a tension fine-tuning component 2. The lower end of each tension fine-tuning component 2 extends into the base 1 and is connected to a two-axis degree-of-freedom adjustment mechanism 3. The lower ends of the two-axis degree-of-freedom adjustment mechanisms 3 are movably connected to the inner wall of the base 1 via a movable seat 4. The two-axis degree-of-freedom adjustment mechanisms 3 drive the tension fine-tuning component 2 to move within the horizontal grooves 9 and horizontal vertical grooves 10, thereby achieving adjustment of the tension fine-tuning component 2 along the horizontal x-axis and y-axis. Slide plates 5 are connected between the two-axis degree-of-freedom adjustment mechanisms 3. The upper and lower ends of each slide plate 5 are slidably connected to corresponding slide rails 7, and a clearance cavity 6 is provided between the slide plates 5.

[0026] The tension adjustment component 2 includes a frustum 21. The frustum 21 is connected to the two-axis degree-of-freedom adjustment mechanism 3 via a rotating column 22. A housing 23 is provided in the middle of the upper surface of the frustum 21. Several support columns 24 are evenly spaced on the outer periphery of the housing 23. Each pair of support columns 24 has an inverted "U"-shaped clearance groove 25. A lifting block 26 is provided inside the clearance groove 25. A screw 28 is installed on the top surface of the lifting block 26. The screw 28 extends upward through the housing 23 and is connected to the housing 23 through a threaded sleeve 27. A driver 29 is poweredly connected to the top of the screw 28.

[0027] The lifting block 26 is equipped with a hinge seat 201 at the corresponding clearance groove 25 on its outer periphery. A connecting rod 202 is connected to the hinge seat 201. The upper end of the connecting rod 202 is movably connected to the hinge seat 201 through a shaft pin 203, and the lower end is movably connected to a winding plate 204.

[0028] In this embodiment, the working principle of the tension adjustment component is as follows: the cable is wound inside the winding plate, and the driver drives the lifting block to move up and down through the screw. The lifting block drives the adjusting rod to expand or contract through the connecting rod, thereby adjusting the tension of the cable and solving the problem of the cable being too loose or too tight in different seasons. In actual use, it has multiple working modes, as follows: ① When the cable route is perpendicular to the upper surface of the base (in practical applications, it is not necessary to be perpendicular, i.e., the cable route is perpendicular to the base surface), Figure 2 The base shown has a consistent short-side orientation. At this point, the cable and the long side of the base's upper surface form a certain angle (which can be 90° or other angles). Since multiple tension adjustment components are provided on the base's upper surface, the device of this invention can be applied to multiple cables with the same orientation simultaneously. This invention is also applicable when the spacing between these multiple cables is not uniform. First, based on the spacing between the multiple cables, a two-axis degree-of-freedom adjustment mechanism is used to move the tension adjustment components within a horizontal groove, thereby changing the distance between the tension adjustment components. This makes it easier to adapt to the design requirements of transmission lines with different spacing types, improving the device's adaptability. Then, rotation... The column drives the tension adjustment assembly to rotate, causing one of the winding plates to rotate to the position of the cable. The cable is then placed inside the clamping plate of the winding plate. The limiting plate limits the cable to prevent it from coming out of the clamping plate. In actual use, to further improve the limiting effect, the limiting plate can be set as a lifting structure or a telescopic plate structure. After the cable is placed inside the clamping plate, the limiting plate is used to close the clamping plate, improving the limiting effect. Then, the driver drives the lifting block to move up and down through the screw. The lifting block drives the adjusting rod to expand outward or retract inward through the connecting rod, thereby adjusting the tension of the cable and solving the problem of the cable being too loose or too tight in different seasons.

[0029] ② When the cable route is parallel to the upper surface of the base (in practical applications, it is not necessary to be parallel, i.e., the cable route is parallel to the upper surface of the base), Figure 2 The long sides of the base shown in the diagram run in the same direction. At this point, the cable and the short side of the upper surface of the base form a certain angle (which can be 90° or other angles). The device of this invention has two operating states: one is where multiple tension / adjustment components are arranged crosswise, such as... Figure 2 As shown, one tension adjustment component is located in front of the base, an adjacent tension adjustment component is located behind the base, and then the next tension adjustment component is located in front of the base. A two-axis adjustment mechanism moves the tension adjustment components within a horizontal longitudinal groove to achieve their cross-setting. Furthermore, by changing the relative positions of the tension adjustment components within the horizontal longitudinal groove, the cross-interval distance between them is changed, making it easier to adapt to dual cables with different spacings, thus improving the device's adaptability. In this case, the invention is applicable to dual cables with this orientation and can make adaptive adjustments based on the cable spacing. Alternatively, multiple tension adjustment components are located on the same connecting line. In this case, the invention is applicable to... Two cables with a fixed spacing are used. A rotating column drives a tension adjustment assembly to rotate, causing one of the winding plates to rotate to the position of the cable. The cable is then placed inside the clamping plate of the winding plate. A limiting plate restricts the cable, preventing it from slipping out. In practical use, to further improve the limiting effect, the limiting plate can be configured as a lifting or telescopic structure. After the cable is placed inside the clamping plate, the limiting plate closes it, enhancing the limiting effect. The driver then uses a screw to move a lifting block up and down. The lifting block, through a connecting rod, moves an adjusting rod outward or inward, thereby adjusting the cable tension and solving the problem of the cable being too loose or too tight in different seasons.

[0030] ③ When the cable route is the same as in ①, since multiple tension adjustment components are provided on the upper surface of the base, the device of the present invention can be applied to multiple cables with the same route simultaneously. Even when the spacing between these multiple cables is not uniform, the present invention is still applicable. First, based on the spacing between the multiple cables, the two-axis degree-of-freedom adjustment mechanism drives the tension adjustment components to move within the horizontal groove, thereby changing the distance between the tension adjustment components to better adapt to the design requirements of transmission lines with different spacing types, improving the adaptability of the device. Then, the cable is wound around the winding plate, that is, the cable is wound around the tension adjustment plate. The cable is wound sequentially around multiple winding plates on the tension adjustment component, and a limiting plate restricts the cable to prevent it from coming out of the clamping plate. In actual use, to further improve the limiting effect, the limiting plate can be set as a lifting structure or a telescopic plate structure. After the cable is placed inside the clamping plate, the limiting plate is used to close the clamping plate, improving the limiting effect. Then, the driver drives the lifting block to move up and down through the screw. The lifting block drives the adjusting rod to expand outward or contract inward through the connecting rod, thereby adjusting the tension of the cable and solving the problem of the cable being too loose or too tight in different seasons.

[0031] ④ When the cable routing is the same as in ②, the device of the present invention has two working states: one is that multiple tension adjustment components are arranged crosswise, such as... Figure 2As shown, one tension adjustment component is located in front of the base, an adjacent tension adjustment component is located behind the base, and then the next tension adjustment component is located in front of the base. A two-axis degree-of-freedom adjustment mechanism moves the tension adjustment components within a horizontal longitudinal groove to achieve their cross-setting. Furthermore, by changing the relative positions of the tension adjustment components within the horizontal longitudinal groove, the cross-interval distance between them is changed, making it easier to adapt to double cables with different spacings, thus improving the device's adaptability. In this case, the invention is applicable to double cables with this orientation and can make adaptive adjustments according to the cable spacing. Then, a rotating column drives the tension adjustment components to rotate, causing the winding plates of multiple tension adjustment components located on the same side of the base to rotate to the cable location. The cable is then wound around the winding plates, that is, the cable wraps around the tension adjustment components on the same side, and the cable is sequentially wound inside the clamping plates of multiple winding plates on the tension adjustment components (the specific operation steps can be abstracted as follows: the same side...). Multiple tension adjustment components can be understood as guide wheels, with the cable sequentially winding through them. A limiting plate restricts the cable's movement, preventing it from slipping out of the clamping plate. In practical use, to further improve the limiting effect, the limiting plate can be configured as a lifting or telescopic structure. After the cable is placed inside the clamping plate, the limiting plate closes it, enhancing the limiting effect. Then, the driver moves the lifting block up and down via a screw. The lifting block, through a connecting rod, expands or contracts the adjusting rod, thereby adjusting the cable tension and solving the problem of the cable being too loose or too tight in different seasons. Alternatively, multiple tension adjustment components can be located on the same line. In this case, the invention is applicable to a single cable. The cable is wound around a winding plate, i.e., the cable is sequentially wound around multiple winding plates on the tension adjustment components (the specific operation steps can be abstractly understood as guide wheels on the same side, with the cable sequentially winding through them), and then adjustment is performed.

[0032] The winding plate 204 includes an adjusting rod 41, which is movably connected to a guide frame 205 located on the upper surface of the frustum 21. The inner end of the adjusting rod 41 is provided with a U-shaped groove 42 that is movably connected to the connecting rod 202. Each U-shaped groove 42 is provided with a through hole 43. The outer end of the adjusting rod 41, which passes through the guide frame 205, is provided with a U-shaped wire clamping plate 44 that rotates 90° counterclockwise. The wire clamping plate 44 is provided with a limit plate 45 longitudinally arranged inside.

[0033] The two-axis degree-of-freedom adjustment mechanism 3 includes a set of symmetrically arranged fixed plates 31. Each fixed plate 31 has a track 32 on its inner side. Each track 32 has a sliding block 33. Each sliding block 33 has a telescopic outer square column 34 on its inner side. Each telescopic outer square column 34 has a telescopic inner square column 35 on its inner side. Both ends of the telescopic inner square column 35 are respectively embedded and slidably installed with the telescopic outer square column 34. Each telescopic outer square column 34 is locked to the telescopic inner square column 35 by an automatic positioner 36.

[0034] The telescopic embedded square column 35 has a sinking groove 37 on both its upper and lower surfaces. A movable block 38 is sleeved on the outside of the telescopic embedded square column 35. The movable block 38 is connected to the rotating column 22 on its upper surface. The upper and lower sides of the movable block 38 are connected to the sinking groove 37 through movable wheels 39. A counterweight 301 is provided at the lower part of the movable block 38. A main controller 302 is provided on the left side of the counterweight 301. Stabilizing rods 303 connected to the movable seat 4 are provided on both the front and rear sides of the counterweight 301.

[0035] In this embodiment, the working principle of the two-axis degree-of-freedom adjustment mechanism is as follows: Since the moving block is connected to the rotating column of the tension adjustment component, the main controller controls the moving block to move in the sinking groove of the telescopic embedded square column using the moving wheel, thereby enabling the moving block to drive the tension adjustment component to move in the horizontal groove, which facilitates changing the spacing between multiple tension adjustment components; in addition, the main controller controls the slide to slide on the track, thereby enabling the moving block, the telescopic embedded square column and the telescopic outer square column to drive the tension adjustment component to move in the horizontal longitudinal groove, which facilitates changing the relative distance when multiple tension adjustment components are cross-set.

[0036] The telescopic outer square columns at both ends are connected to the telescopic inner square columns in a telescopic cooperation. When the telescopic outer square column on the side closer to the slide plate of the two-axis degree-of-freedom adjustment mechanism located at both ends inside the base contracts or extends with the corresponding telescopic inner square column (the two-axis degree-of-freedom adjustment mechanism located in the middle of the base has adjustable telescopic outer square columns on both sides), it will drive the corresponding slide plate to slide in the slide rail to ensure the stability and reliability of the telescopic outer square column's movement. Moreover, the clearance cavity provides movement space for the sliding movement of the slide plates on both sides. When the telescopic outer square column contracts or extends with the corresponding telescopic inner square column, the overall relative length of the telescopic inner square column will change. That is, the moving block moves in the sinking groove of the telescopic inner square column using the moving wheel, which changes the displacement of the tension fine-tuning component.

[0037] This invention relates to a power transmission line slack adjustment device and its usage method. During installation, the device is mounted on a base 1 at the corresponding work location. Based on the power transmission line design and requirements, a two-axis adjustment mechanism 3 moves the tension adjustment component 2 within the horizontal transverse groove 9 and / or horizontal longitudinal groove 10, changing the position of the tension adjustment component 2. This allows the spacing between adjacent tension adjustment components 2 to be adjusted according to actual needs. The rotation column 22 can also rotate the tension adjustment component 2, thereby adjusting the direction of the winding plate 204. Subsequently, according to the cable's direction, the cable is placed inside the corresponding winding plate 204. When the cable is in a slack or over-tight state, the driver 29 moves the lifting block 26 up and down via the screw 28. The lifting block 26, via the connecting rod 202, causes the adjusting rod 41 to expand or contract relative to the guide frame 205. The clamping plate 44 moves the cable, thereby tightening or loosening the cable and initially adjusting its slack, thus solving the problem of cable tension being too high or too low. The problem of excessive looseness or tightness during the same season is addressed. Then, based on the cable's direction, the guide wheel assembly 82 of the quick-adjustment assembly 8 is adjusted using the steering assembly 83 to be located on the front and rear sides or the left and right sides of the base 1. The locking hole 12, the lifting locking rod 13, and the locking tongue 312 are used to lock the state. The cable is then placed inside the cable clamping plate 44 after passing through the corresponding adjusting guide wheel 213. Then, the rail seat 212 slides on the horizontal rail 211, thereby driving the adjusting guide wheel 213 to move. This causes the adjusting guide wheel 213 to pull a portion of the cable to slide on the horizontal rail 211 and form a bend with the cable clamping plate 44, thereby tightening the cable. The cable clamping plate 44, together with the limiting plate 45, supports and limits the cable. At the same time, by adjusting the guide wheel 213 to pull a portion of the cable to slide in the opposite direction on the horizontal rail 211, the degree of bending of the cable is reduced, thus achieving cable slack adjustment. This invention has the advantages of simple and reasonable structure, applicability to multi-direction cables, applicability to multi-spacing cables, good performance, and strong practicality.

Each horizontal groove 9 contains a horizontal vertical groove 10, and each horizontal vertical groove 10 contains a tension fine-tuning component 2. The lower end of each tension fine-tuning component 2 extends into the base 1 and is connected to a two-axis degree-of-freedom adjustment mechanism 3. The lower ends of the two-axis degree-of-freedom adjustment mechanisms 3 are movably connected to the inner wall of the base 1 via a movable seat 4. The two-axis degree-of-freedom adjustment mechanisms 3 drive the tension fine-tuning component 2 to move within the horizontal grooves 9 and horizontal vertical grooves 10, thereby achieving adjustment of the tension fine-tuning component 2 along the horizontal x-axis and y-axis. Slide plates 5 are connected between the two-axis degree-of-freedom adjustment mechanisms 3. The upper and lower ends of each slide plate 5 are slidably connected to corresponding slide rails 7, and a clearance cavity 6 is provided between the slide plates 5.

[0039] A transmission line slack adjustment device further includes a quick-adjustment assembly 8, which is located between two pairs of fine-tuning assemblies 2. The quick-adjustment assembly 8 includes a chassis 81 located on the upper surface of a base 1. A guide wheel assembly 82 is mounted on the chassis 81. A steering assembly 83 is provided between the chassis 81 and the guide wheel assembly 82. The steering assembly 83 drives the guide wheel assembly 82 to move, thereby adjusting its direction. A set of positioning posts 11 is provided on the upper surface of the chassis 81. A set of locking holes 12 is provided inside the positioning posts 11. Each locking hole 12 is provided with a lifting locking rod 13.

[0040] The guide wheel assembly 82 includes a base plate 210, on the upper surface of which a set of horizontal rails 211 are symmetrically arranged. Each horizontal rail 211 is slidably mounted with a rail seat 212, and each rail seat 212 is mounted with an adjusting guide wheel 213.

[0041] In this embodiment, the working principle of the quick-adjustment assembly is as follows: when the cable route is parallel to the upper surface of the base, that is, the same as state ② above, the quick-adjustment assembly is perpendicular to the upper surface of the base, such as... Figure 6As shown, the quick-adjustment assembly has two working states. In one state, one of the adjusting guide wheels in the multiple guide wheel assemblies is located on one side of the base, and the other adjusting guide wheel is located on the other side of the base. That is, the cable passes through the adjusting guide wheels located on the same side of the base in sequence. Then, the rail seat moves on the horizontal rail, driving the adjusting guide wheels to move, so that the edge of the guide wheel base moves laterally towards its center. This causes the adjusting guide wheel to pull a part of the cable to move in the center of the base, making the part of the cable passing through the guide assembly arc-shaped. Of course, one or more of the adjusting guide wheels (adjusted according to the actual situation) can also be used as positioning rollers to keep their positions unchanged. Then, when the adjusting guide wheel drives the cable to move, it forms a bend with the positioning roller, thereby tightening the cable. This is suitable for two cables. In the other state, the adjusting guide wheels of each guide wheel assembly are located on both sides, and the line connecting the center points of the multiple adjusting guide wheels is a broken line. Then, the cable passes through the multiple adjusting guide wheels in sequence, and then the relaxation adjustment is performed according to the above adjustment operation. This is suitable for a single cable.

[0042] When the cable route is perpendicular to the upper surface of the base, the situation is the same as in state ① above. In this case, the quick-adjustment assembly is adjusted using the steering assembly to make it parallel to the upper surface of the base. Figure 8 As shown, the quick-adjustment assembly has two working states at this time. The first state is that the adjusting guide wheels of the multiple guide wheel assemblies are located on both sides of the base plate, as shown. Figure 8 In the first configuration, the cables are threaded through the corresponding adjusting guide wheels, and then the cables are moved using these wheels for adjustment. Each guide wheel assembly can be used to adjust two cables, and the overall configuration is suitable for multiple cables. The second configuration has multiple guide wheel assemblies with their adjusting guide wheels located on both sides of the base plate, such as... Figure 8 As shown, the cable passes through the adjusting guide wheels on the left and right sides respectively, and then the adjusting guide wheels are used to pull the cable to make adjustments. Each guide wheel assembly can be used for adjusting a single cable. Alternatively, when the adjusting guide wheels of multiple guide wheel assemblies are located on one side of the base plate (left or right, and adjacent guide wheel assemblies on different sides can accommodate cable spacing), the cable passes through two adjusting guide wheels on the same side, and then the adjusting guide wheels are used to pull the cable to make adjustments. Each guide wheel assembly can be used for adjusting a single cable, and the assembly is suitable for multiple cables. Of course, other operating states may occur in actual use, which will not be described further here.

[0043] Specifically, the guide wheel assembly of the present invention can also be used in conjunction with the tension fine-tuning assembly. A simple example is given below: when the cable route is perpendicular to the upper surface of the base, one of the cables is located inside the cable clamping plate and passes through one of the adjusting guide wheels of the guide wheel assembly or both adjusting guide wheels simultaneously. When both adjusting guide wheels pass through simultaneously, they can be located on the same side or different sides. The two adjusting guide wheels can then act as positioning rollers. The lifting block, through a connecting rod, drives the adjusting rod to expand or contract relative to the guide frame. The cable clamping plate moves the cable, causing it to bend between itself and the two adjusting guide wheels, thereby tightening the cable. Alternatively, the cable clamping plate can also act as a positioning roller, and the rail base moves on the horizontal rail, driving the adjusting guide wheels to move, causing the adjusting guide wheels to pull the cable and the cable clamping plate into a bent shape, thus tightening the cable. When the cable passes through one of the adjusting guide wheels of the guide wheel assembly, the two adjusting guide wheels are not on the same side. One cable is inside the cable clamping plate and passes through one of the adjusting guide wheels, while the other cable is inside the cable clamping plate of another tension fine-tuning assembly and passes through the other adjusting guide wheel. This is suitable for multiple cables. Then, the cable clamping plate or adjusting guide wheel is used as a positioning roller, and the slack of the cable can be adjusted.

[0044] Similarly, when the cable route is parallel to the upper surface of the base, simply use the steering assembly to adjust the guide wheel assembly to be parallel to the upper surface of the base, such as... Figure 8 As shown, adjustments can then be made according to requirements and cable routing. Of course, other operating states may occur during actual use, which will not be elaborated here. This invention utilizes either a fine-tuning component or a quick-adjustment component to adjust cable slack independently. It can also use the fine-tuning and quick-adjustment components in combination to adjust cable slack. This allows the invention to adapt to single, double, and multiple cable adjustments, as well as individual or simultaneous adjustments of cables with different routing / directions, and adjustments of cables with different spacing. This essentially covers all aspects of cable slack adjustment, greatly improving practicality, versatility, and flexibility, resulting in better performance.

[0045] The steering assembly 83 includes a rotating gear disk 310 located in the middle of the chassis 81. The upper surface of the rotating gear disk 310 is connected to the lower surface of the base plate 210 through a connecting block 311. A locking tongue 312 is provided on one side of the rotating gear disk 310 corresponding to the lifting locking rod 13, and an incompletely curved toothed plate 313 is provided on the other side. The steering assembly 83 also includes a linear actuator 314 located on one side of the upper surface of the chassis 81. A drive plate 315 is installed at the output end of the linear actuator 314. A straight toothed plate 316 is connected to the drive plate 315. The straight toothed plate 316 is meshed with the incompletely curved toothed plate 313, and the lower surface of the straight toothed plate 316 is slidably connected to the longitudinal rail 317.

[0046] In this embodiment, the working principle of the steering assembly is as follows: the lifting locking lever moves down, releasing the locking state of the locking tongue. The linear actuator drives the straight toothed plate to move on the longitudinal rail via the drive plate. Since the straight toothed plate meshes with the partially curved toothed plate, when the straight toothed plate moves, it drives the partially curved toothed plate to move, which in turn drives the rotating gear plate to rotate. The rotating gear plate drives the guide wheel assembly to rotate as a whole via the connecting block, realizing the direction adjustment of the guide wheel assembly. This facilitates practical adjustment according to the cable routing. When the adjustment is in place, the lifting locking lever inside the locking hole rises, cooperating with the corresponding positioning post to lock and limit the locking tongue located between the lifting locking lever and the positioning post. Figure 7 As shown, this achieves state locking of the guide wheel assembly, ensuring that it remains in a stable state during operation.

[0047] This invention relates to a power transmission line slack adjustment device and its usage method. During installation, the device is mounted on a base 1 at the corresponding work location. Based on the power transmission line design and requirements, a two-axis adjustment mechanism 3 moves the tension adjustment component 2 within the horizontal transverse groove 9 and / or horizontal longitudinal groove 10, changing the position of the tension adjustment component 2. This allows the spacing between adjacent tension adjustment components 2 to be adjusted according to actual needs. The rotation column 22 can also rotate the tension adjustment component 2, thereby adjusting the direction of the winding plate 204. Subsequently, according to the cable's direction, the cable is placed inside the corresponding winding plate 204. When the cable is in a slack or over-tight state, the driver 29 moves the lifting block 26 up and down via the screw 28. The lifting block 26, via the connecting rod 202, causes the adjusting rod 41 to expand or contract relative to the guide frame 205. The clamping plate 44 moves the cable, thereby tightening or loosening the cable and initially adjusting its slack, thus solving the problem of cable tension being too high or too low. The problem of excessive looseness or tightness during the same season is addressed. Then, based on the cable's direction, the guide wheel assembly 82 of the quick-adjustment assembly 8 is adjusted using the steering assembly 83 to be located on the front and rear sides or the left and right sides of the base 1. The locking hole 12, the lifting locking rod 13, and the locking tongue 312 are used to lock the state. The cable is then placed inside the cable clamping plate 44 after passing through the corresponding adjusting guide wheel 213. Then, the rail seat 212 slides on the horizontal rail 211, thereby driving the adjusting guide wheel 213 to move. This causes the adjusting guide wheel 213 to pull a portion of the cable to slide on the horizontal rail 211 and form a bend with the cable clamping plate 44, thereby tightening the cable. The cable clamping plate 44, together with the limiting plate 45, supports and limits the cable. At the same time, by adjusting the guide wheel 213 to pull a portion of the cable to slide in the opposite direction on the horizontal rail 211, the degree of bending of the cable is reduced, thus achieving cable slack adjustment. This invention has the advantages of simple and reasonable structure, applicability to multi-direction cables, applicability to multi-spacing cables, good performance, and strong practicality. Example 3

[0048] like Figures 1-4 As shown, a method of using a transmission line slack adjustment device is described. Based on the transmission line slack adjustment device described above, the slack adjustment of the transmission line cable is achieved. The method includes the following steps: Step 1: During installation, the base 1 is used to install it at the corresponding working location. According to the design and requirements of the power transmission line, the tension adjustment component 2 is moved in the horizontal groove 9 and / or the horizontal longitudinal groove 10 by the two-axis degree of freedom adjustment mechanism 3, so that the position of the tension adjustment component 2 changes, thereby adjusting the distance between adjacent tension adjustment components 2 according to actual needs. The tension adjustment component 2 can be rotated by the rotating column 22, thereby adjusting the direction of the winding plate 204. Step 2: Subsequently, according to the cable routing, the cable is placed inside the corresponding winding plate 204. When the cable is in a slack or too tight state, the driver 29 drives the lifting block 26 to move up and down through the screw 28. The lifting block 26 drives the adjusting rod 41 to expand or contract relative to the guide frame 205 through the connecting rod 202. The cable clamping plate 44 drives the cable to move, thereby tightening or loosening the cable, thus making preliminary adjustments to the cable tension and solving the problem of the cable being too slack or too tight in different seasons. Step 3: Then, according to the direction of the cable, use the steering component 83 to adjust the guide wheel component 82 of the tension quick adjustment component 8 to be located on the front and rear sides of the base 1 or on the left and right sides of the base. Use the locking hole 12, the lifting locking rod 13 and the locking tongue 312 to lock the state. After the cable passes through the corresponding adjusting guide wheel 213, it is placed inside the cable clamping plate 44. Step 4: Then, the rail seat 212 slides on the horizontal rail 211, thereby driving the adjusting guide wheel 213 to move. The adjusting guide wheel 213 pulls a part of the cable to slide on the horizontal rail 211 and forms a bend with the cable clamping plate 44, thereby tightening the cable. The cable clamping plate 44, together with the limiting plate 45, supports and limits the cable. At the same time, by adjusting the guide wheel 213 pulling a part of the cable to slide in the opposite direction on the horizontal rail 211, the degree of bending of the cable is reduced, thereby realizing the cable slack adjustment.
