Description

Technical Field

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

[0002] Electric power engineering is related to the production, transmission, and distribution of electric energy. During the electric power construction process, it is common to tension cables between utility poles as the main means of laying the power grid. In this process, each cable and the utility pole are fastened manually. Therefore, during long-term use, the cables suspended between each utility pole will shake continuously due to reasons such as wind and rain, resulting in varying degrees of loosening or deformation, causing the cables between the two utility poles to gradually stretch and become loose. The loose cables are prone to large swings under the influence of wind, etc., leading to power accidents. When electricians carry out electric power construction, in order to ensure the safety and standardization of cable erection, they often need to erect the cables at a high place and tension them during construction to prevent unstable swaying during cable use or short-circuit faults caused by contact between cables. Therefore, a cable tensioning device is used to tension the cables.

[0003] Currently, after the existing cable tensioning device tensions the cable, it is inconvenient to loosen it, making the control of the cable less flexible and bringing inconvenience to subsequent cable maintenance. At the same time, affected by the cable being installed outdoors, when the wind blows, the cable may fall off, thereby affecting the cable tensioning effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cable tensioning device for electric power engineering construction, comprising: a housing, which has a shell with a supporting function, a flat cover plate is fixedly installed on the side of the housing, and a base is fixedly installed at the bottom of the housing; a cable winding mechanism, which is used to tension the cable, and the cable winding mechanism is installed in the middle of the outside of the housing. Among them, the cable winding mechanism includes a servo motor and a winding wheel. The servo motor is installed inside the housing. The central axis on the outside of the winding wheel is rotatably installed at the middle of the outside of the housing. The central axis of the winding wheel penetrates the outside of the housing and extends to its interior. The output shaft of the servo motor is fixedly installed with the central axis of the winding wheel through a coupling. First annular grooves and second annular grooves are respectively opened at corresponding positions on the outside of the winding wheel. A trapezoidal notch is opened in the middle of the outside of the winding wheel. Anti-slip blocks are fixedly installed at the bottom of the inner wall of the first annular groove and the bottom of the inner wall of the second annular groove. A linear hole is opened at the side of the outside of the winding wheel. One side of the cable to be tensioned is wound from the first annular groove, and the cable is passed through the trapezoidal notch. At this time, the other side of the cable is wound reversely in the second annular groove. At this time, both ends of the cable extend out from two symmetrically arranged pressing plates up and down; when the cable needs to be tensioned, by using the rotation of the output end of the servo motor, the winding wheel can be driven to rotate clockwise. Then, through the rotation of the winding wheel, the cables on both sides are wound, and then the cable is wound and tensioned; at the same time, by using the softness of the anti-slip blocks to play an anti-slip role, it is not easy for the winding wheel to slip when winding the cable; The cable tensioning device for electric power engineering construction further includes: A wire pressing mechanism, which is used to press the cable, and the wire pressing mechanism is installed at the side of the outside of the housing; among them, the wire pressing mechanism includes a Z-shaped plate and a connecting guide post. The Z-shaped plate is fixedly installed at the edge of the outside of the housing. A round hole is opened on the stepped surface of the outside of the Z-shaped plate. The connecting guide post is slidably installed with the Z-shaped plate through the round hole. A pressing component is installed at the end of the connecting guide post away from the Z-shaped plate. A diamond-shaped elastic frame is fixedly installed between the pressing component and the Z-shaped plate. When the cable is wound and tensioned with the rotation of the winding wheel, under the supporting and guiding action of the connecting guide post, two centrally symmetric pressing components are on the surface of the cable in the wound state, so that the cable is limited; at the same time, under the elastic force of the diamond-shaped elastic frame, the cable is elastically pressed, reducing the influence of wind blowing, and thus it is not easy for the cable to become loose.

[0005] Preferably, the first annular groove and the second annular groove are symmetrical along the trapezoidal notch. The anti-slip blocks are evenly distributed at the bottom of the inner wall of the first annular groove and the bottom of the inner wall of the second annular groove, and the material of the anti-slip blocks is rubber. When it is necessary to loosen the cable, only the output end of the servo motor needs to rotate in the reverse direction. At this time, the winding wheel is driven to rotate counterclockwise, and then the cable wound on the surface of the winding wheel is released. Then, by the different states of the clockwise and counterclockwise rotation of the winding wheel, the winding and tightening and loosening of the cable are realized, making the control of the cable by the equipment more flexible.

[0006] Preferably, there are two of the linear holes, and the two linear holes are symmetrically installed along the axis of the center of the winding wheel, which is convenient for clamping.

[0007] Preferably, there are two of the Z-shaped plates, and the two Z-shaped plates are symmetrically installed along the housing. The pressing assembly is installed at a position close to the winding wheel.

[0008] Preferably, the pressing assembly includes a pressing plate. The top of the pressing plate is fixedly installed with the bottom end of the connecting guide post. An arc-shaped surface inside the pressing plate is fixedly installed with a flexible pad. A V-shaped groove is opened at the arc-shaped surface inside the flexible pad. A support elastic strip is fixedly installed at the side of the outside of the pressing plate. A round ball is fixedly installed at the end of the support elastic strip away from the pressing plate. When the pressing plate presses the cable wound on its surface, the flexible pad is used to be between the pressing plate and the cable. At this time, the cable is in flexible contact, thereby protecting the cable and not easily causing damage to the cable.

[0009] Preferably, the pressing plate is arc-shaped, which is convenient for clamping on the surface of the winding wheel. The material of the flexible pad is rubber. The V-shaped grooves are evenly distributed at the arc-shaped surface inside the flexible pad, which can increase the contact area.

[0010] Using the elastic force provided by the support elastic strip, the round ball is subjected to an elastic pressing force, so that the outer semicircle of the round ball is embedded into the inside of the linear hole, thereby realizing the clamping function and making the structure clamped together, and it is not easy to loosen the structure.

[0011] Preferably, an adjusting component is installed at the side of the outer shell. The adjusting component includes an electric telescopic rod. The output end of the electric telescopic rod is fixedly installed with a U-shaped substrate. The opening of the U-shaped substrate faces away from the electric telescopic rod. The electric telescopic rod is installed near the pressing component, and the U-shaped substrate is installed near the wire winding wheel. Strip-shaped holes are opened at corresponding positions on the outside of the U-shaped substrate. A first round rod is rotatably installed at one end of the wire winding wheel away from the electric telescopic rod. An auxiliary module is installed in the middle of the U-shaped substrate. The cable passes through between the first round rod and the auxiliary module, and the staff starts the electric telescopic rod to work. At this time, the output end of the electric telescopic rod contracts, driving the U-shaped substrate to move, and then driving the first round rod and the auxiliary module to move together. At this time, the cable is subjected to a pulling force, and the cable is in an inclined state, making the outside of the cable winding wheel present a tangent state, which helps to wind the cable.

[0012] Preferably, there are two electric telescopic rods, and the two electric telescopic rods are symmetrically installed along the axis of the center of the wire winding wheel. There are two U-shaped substrates, and the two U-shaped substrates are symmetrically installed along the axis of the center of the wire winding wheel.

[0013] Preferably, the auxiliary module includes a rectangular slider and a second round rod. The inner side of the rectangular slider is slidably installed at the middle of the outside of the U-shaped substrate. Springs are fixedly installed between the bottom of the rectangular slider and the corresponding two sides of the inner wall of the strip-shaped hole. A bushing is fixedly installed at the middle of the top of the rectangular slider. A circular hole is opened at the center of the bushing. The two ends of the second round rod are installed at the center of the bushing through the circular hole. The second round rod is installed directly below the first round rod. The elastic force provided by the spring makes the first round rod and the second round rod elastically clamp the cable, and it is not easy to cause clamp marks on the surface of the cable. At the same time, both the first round rod and the second round rod can roll, reducing the frictional resistance and making the wound cable move smoothly.

[0014] Preferably, the bushing is installed directly above the rectangular slider, and the axis of the first round rod is parallel to the axis of the second round rod, which is convenient for the first round rod and the second round rod to clamp and limit the cable together, and it is not easy to deviate.

[0015] The present invention provides a cable tensioning device for electric power engineering construction. It has the following beneficial effects: 1. For the cable tensioning device in the power engineering construction, one side of the cable to be tensioned is wound from the first annular groove, and the cable is passed through the trapezoidal notch. At this time, the other side of the cable is wound reversely in the second annular groove. At this time, both ends of the cable extend outward from the upper and lower symmetric pressing plates. When the cable needs to be tensioned, the rotation of the output end of the servo motor can drive the winding wheel to rotate clockwise. Then, through the rotation of the winding wheel, the cables on both sides are wound, and thus the cable is wound and tensioned. At the same time, due to the softness of the anti-slip block, the anti-slip effect is achieved, so that the winding of the cable by the winding wheel is not prone to slipping.

[0016] 2. For the cable tensioning device in the power engineering construction, when the cable needs to be loosened, only the output end of the servo motor needs to rotate reversely. At this time, the winding wheel is driven to rotate counterclockwise, and then the cable wound on the surface of the winding wheel is released. Then, through the different states of the clockwise and counterclockwise rotation of the winding wheel, the winding, tensioning and loosening of the cable are realized, making the control of the cable by the device more flexible.

[0017] 3. For the cable tensioning device in the power engineering construction, when the cable is wound and tensioned with the rotation of the winding wheel, under the supporting and guiding action of the connecting guide post, the two centrally symmetric clamping components are on the surface of the cable in the wound state, so that the cable is limited. At the same time, under the elastic force of the rhombic elastic frame, the cable is elastically pressed, reducing the influence of the wind, and thus the cable is not prone to loosening.

[0018] 4. For the cable tensioning device in the power engineering construction, when the pressing plate presses the cable wound on its surface, the flexible pad is between the pressing plate and the cable. At this time, the cable is in flexible contact, and thus the cable is protected and not easily damaged.

[0019] 5. For the cable tensioning device in the power engineering construction, the elastic force provided by the supporting elastic strip makes the spherical ball receive an elastic pressing force, so that the semicircle outside the spherical ball is embedded into the inside of the straight slot hole, and thus the clamping effect is achieved, making the structure clamped together and not prone to structural loosening.

[0020] 6. For the cable tensioning device in the power engineering construction, the cable passes through between the first round rod and the auxiliary module, and the electric telescopic rod is started by the staff to work. At this time, the output end of the electric telescopic rod contracts, driving the U-shaped substrate to move, and then the first round rod and the auxiliary module are driven to move together. At this time, the cable receives a pulling force, and the cable is in an inclined state, making the outside of the cable winding wheel easy to present a tangent state, which is helpful for the winding of the cable.

[0021] VII. For the cable tensioning device in the construction of the power project, after the cable passes through between the first round rod and the second round rod, the elastic force provided by the spring is utilized to enable the first round rod and the second round rod to elastically clamp the cable, which is not likely to cause clamping marks on the surface of the cable. At the same time, since both the first round rod and the second round rod can roll, the frictional resistance is reduced, making the wound cable move smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

The cable winding mechanism 3 is installed in the middle of the outside of the housing 1. Among them, the cable winding mechanism 3 includes a servo motor 31 and a winding wheel 32. The servo motor 31 is installed inside the housing 1. The central axis outside the winding wheel 32 is rotatably installed at the middle of the outside of the housing 1. The central axis of the winding wheel 32 penetrates the outside of the housing 1 and extends to its interior. The output shaft of the servo motor 31 is fixedly installed with the central axis of the winding wheel 32 through a coupling. First annular grooves 33 and second annular grooves 34 are respectively opened at corresponding positions on the outside of the winding wheel 32. A trapezoidal notch 35 is opened at the middle of the outside of the winding wheel 32. Anti-slip blocks 36 are fixedly installed at the bottom of the inner wall of the first annular groove 33 and the bottom of the inner wall of the second annular groove 34. A linear hole 37 is opened at the side of the outside of the winding wheel 32. One side of the cable to be tensioned is wound from the first annular groove 33, and the cable is passed through the trapezoidal notch 35. At this time, the other side of the cable is wound reversely in the second annular groove 34; when the cable needs to be tensioned, the staff turns on the servo motor 31 to work. By using the rotation of the output end of the servo motor 31, the winding wheel 32 can be driven to rotate clockwise. Then, through the rotation of the winding wheel 32, the cables on both sides are wound, and then the cable is wound and tensioned; at the same time, by using the softness of the anti-slip blocks 36 to play an anti-slip role, it is not easy for the winding wheel 32 to slip when winding the cable; the first annular groove 33 and the second annular groove 34 are symmetric with respect to the trapezoidal notch 35. The anti-slip blocks 36 are evenly distributed at the bottom of the inner wall of the first annular groove 33 and the bottom of the inner wall of the second annular groove 34, and the material of the anti-slip blocks 36 is rubber, which has an anti-slip effect.

[0026] When the cable needs to be loosened, just reverse the rotation of the output end of the servo motor 31. At this time, the winding wheel 32 is driven to rotate counterclockwise, and then the cable wound on the surface of the winding wheel 32 is released. Then, through the different states of the clockwise and counterclockwise rotations of the winding wheel 32, the winding, tensioning and loosening of the cable are realized.

[0027] There are two linear holes 37, and the two linear holes 37 are symmetrically installed along the axis at the center of the winding wheel 32, which is convenient for clamping.

[0028] The second embodiment is as follows Figures 1-7 shown. On the basis of the first embodiment: The cable tensioning device for electric power engineering construction further includes: a wire pressing mechanism 4, which is used to press the cable, and the wire pressing mechanism 4 is installed on the side of the outer side of the housing 1; wherein, the wire pressing mechanism 4 includes a Z-shaped plate 41 and a connecting guide post 42. The Z-shaped plate 41 is fixedly installed at the edge of the outer side of the housing 1. A round hole is provided on the stepped surface on the outer side of the Z-shaped plate 41. The connecting guide post 42 is slidably installed with the Z-shaped plate 41 through the round hole. A pressing component 43 is installed at one end of the connecting guide post 42 away from the Z-shaped plate 41. A diamond-shaped elastic frame 44 is fixedly installed between the pressing component 43 and the Z-shaped plate 41. When the cable is wound and tightened with the rotation of the winding wheel 32, under the supporting and guiding action of the connecting guide post 42, the two centrally symmetric pressing components 43 are on the surface of the cable in the wound state; at the same time, under the elastic force of the diamond-shaped elastic frame 44, the cable is elastically pressed, reducing the influence of wind blowing, and thus the cable is not likely to become loose.

[0029] There are two Z-shaped plates 41, and the two Z-shaped plates 41 are symmetrically installed along the housing 1, and the pressing component 43 is installed at a position close to the winding wheel 32.

[0030] The pressing component 43 includes a pressing plate 431. The top of the pressing plate 431 is fixedly installed with the bottom end of the connecting guide post 42. A flexible pad 432 is fixedly installed on the arc surface inside the pressing plate 431. A V-shaped groove 433 is provided on the arc surface inside the flexible pad 432. A supporting elastic strip 434 is fixedly installed on the side of the outer side of the pressing plate 431. A round ball 435 is fixedly installed at the end of the supporting elastic strip 434 away from the pressing plate 431. When the pressing plate 431 presses the cable wound on its surface, the flexible pad 432 is used between the pressing plate 431 and the cable. At this time, the cable is in flexible contact, thereby protecting the cable.

[0031] The pressing plate 431 is arc-shaped, which is convenient for clamping on the surface of the winding wheel 32. The material of the flexible pad 432 is rubber, and the V-shaped grooves 433 are evenly distributed on the arc surface inside the flexible pad 432, which can increase the contact area.

[0032] Using the elastic force provided by the supporting elastic strip 434, the round ball 435 is elastically pressed, so that the outer semicircle of the round ball 435 is embedded into the linear hole 37, thereby realizing the clamping function.

[0033] The third embodiment is as follows Figures 8-9As shown in the figure, an adjustment component 5 is installed at the side of the outer shell 1. The adjustment component 5 includes an electric telescopic rod 51. The output end of the electric telescopic rod 51 is fixedly installed with a U-shaped substrate 52. The opening of the U-shaped substrate 52 faces away from the electric telescopic rod 51. The electric telescopic rod 51 is installed near the pressing component 43, and the U-shaped substrate 52 is installed near the winding wheel 32. Strip-shaped holes 53 are opened at corresponding positions on the outside of the U-shaped substrate 52. A first round rod 54 is rotatably installed at one end of the winding wheel 32 away from the electric telescopic rod 51. An auxiliary module 55 is installed in the middle of the U-shaped substrate 52. A cable passes through between the first round rod 54 and the auxiliary module 55, and the staff turns on the electric telescopic rod 51 to work. At this time, the output end of the electric telescopic rod 51 contracts, driving the U-shaped substrate 52 to move, and then driving the first round rod 54 and the auxiliary module 55 to move together. At this time, the cable is subjected to a pulling force, and the cable is in an inclined state, so that the cable is in a tangential state on the outside of the winding wheel 32, which helps to wind the cable.

[0034] There are two electric telescopic rods 51, and the two electric telescopic rods 51 are symmetrically installed along the axis of the center of the winding wheel 32. There are two U-shaped substrates 52, and the two U-shaped substrates 52 are symmetrically installed along the axis of the center of the winding wheel 32.

[0035] The auxiliary module 55 includes a rectangular slider 551 and a second round rod 554. The inner side of the rectangular slider 551 is slidably installed at the middle of the outside of the U-shaped substrate 52. Springs 552 are fixedly installed between the bottom of the rectangular slider 551 and the corresponding two sides of the inner wall of the strip-shaped hole 53. A bushing 553 is fixedly installed at the middle of the top of the rectangular slider 551. A circular hole is opened at the center of the bushing 553. The two ends of the second round rod 554 are installed at the center of the bushing 553 through the circular hole. The second round rod 554 is installed directly below the first round rod 54. When the cable passes through between the first round rod 54 and the second round rod 554, the elastic force provided by the spring 552 is used to elastically clamp the cable between the first round rod 54 and the second round rod 554, and it is not easy to cause indentations on the surface of the cable. At the same time, both the first round rod 54 and the second round rod 554 can roll, reducing the frictional resistance and making the wound cable move smoothly.

[0036] The bushing 553 is installed directly above the rectangular slider 551. The axis of the first round rod 54 is parallel to the axis of the second round rod 554, which is convenient for the first round rod 54 and the second round rod 554 to clamp and limit the cable together, and it is not easy to deviate.

[0037] During use, when constructing the cable, first install the entire tensioning device to the designated position through the base 6, pass one end of the cable through between the first round rod 54 and the second round rod 554, wind the side of the cable to be tensioned around the first annular groove 33, and pass the cable through the trapezoidal notch 35. At this time, wind the other side of the cable reversely in the second annular groove 34. At this time, both ends of the cable extend outward from the upper and lower symmetric pressing plates 431; At this time, the cable on the surface of the winding wheel 32 is located between the winding wheel 32 and the pressing plate 431, and the staff starts the electric telescopic rod 51 to work. At this time, the output end of the electric telescopic rod 51 contracts, driving the U-shaped substrate 52 to move, and further driving the first round rod 54 and the auxiliary module 55 to move together. At this time, the cable is subjected to a pulling force, and the cable is in an inclined state, so that the outside of the cable winding wheel 32 is in a tangent state; When the cable needs to be tensioned, the staff starts the servo motor 31 to work. By using the rotation of the output end of the servo motor 31, the winding wheel 32 can be driven to rotate clockwise. Then, through the rotation of the winding wheel 32, the cables on both sides are wound, and the cable is wound and tensioned. Moreover, due to the softness of the anti-slip block 36, the anti-slip effect is achieved, so that the winding of the cable by the winding wheel 32 is not prone to slipping; And when the cable passes through between the first round rod 54 and the second round rod 554, the elastic force provided by the spring 552 is used to elastically clamp the cable by the first round rod 54 and the second round rod 554, which is not easy to cause clamping marks on the surface of the cable. At the same time, since both the first round rod 54 and the second round rod 554 can roll, the frictional resistance is reduced, making the wound cable move smoothly; When the cable is wound and tensioned by the rotation of the winding wheel 32, under the support and guiding action of the connecting guide post 42, the two groups of centrally symmetric pressing components 43 are on the surface of the cable in the wound state. At the same time, under the elastic force of the rhombic elastic frame 44, the cable is elastically pressed, reducing the influence of wind blowing, and thus making the cable not prone to loosening; Moreover, when the pressing plate 431 presses the cable wound on the surface of the winding wheel 32, the flexible pad 432 is located between the pressing plate 431 and the cable. At this time, the cable is in flexible contact, thereby protecting the cable; And the elastic force provided by the support elastic strip 434 is used to make the spherical ball 435 receive an elastic pressing force, so that the semi-circle outside the spherical ball 435 is embedded into the inside of the linear hole 37, thereby realizing the clamping function and making the connection between the structures firm; When the cable needs to be loosened, just reverse the rotation of the output end of the servo motor 31. At this time, the wire winding wheel 32 is driven to rotate counterclockwise, thereby releasing the cable wound on the surface of the wire winding wheel 32. Furthermore, by the different states of the clockwise and counterclockwise rotations of the wire winding wheel 32, the winding, tensioning and loosening of the cable are realized.
