Description

Technical Field

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

[0002] Power construction refers to a series of work on the construction, installation, maintenance and overhaul of power equipment and facilities. It includes multiple links such as planning, design, construction, supervision and acceptance of power projects, and is an important part of ensuring power supply and safe operation.

[0003] When the wires become loose, a wire tightening device is needed to tighten the wires. However, the existing wire tightening device requires manual wire tightening operation when the wires are tightened, which increases the labor burden and reduces the wire tightening efficiency. Moreover, when tightening the wires, it is generally impossible to organize the wound wires, resulting in the wires piling up when they are wound, reducing the winding effect. At the same time, the existing wire tightening device usually does not have a wire stripping structure, resulting in the need for manual wire stripping when the wires are installed after the wire tightening is completed, thereby reducing the wire stripping effect and the wire installation efficiency.

[0004] Therefore, there is an urgent need for a power construction tightening device so that loose wires can be tightened, reducing manual auxiliary tightening, alleviating manual burden, and improving tightening efficiency. Moreover, when tightening the wires, the wound wires can be tidied to avoid accumulation of the wound wires, thereby improving the winding effect. At the same time, when the wires are installed after tightening, the wires can also be stripped to avoid manual stripping of the wires, thereby improving the stripping effect and wire installation efficiency. Summary of the invention

[0054] The present invention provides a method for using a power construction tightening device, comprising the following steps:

[0055] Step 1) Connect the end of a single wire to the hook 204 and place the wire in the wire limiting groove 4010 .

[0056] Step 2) Start the motor 205 to rotate the elliptical wheel 206. When the elliptical wheel 206 rotates to the raised position, the pawl 2010, the ratchet wheel 202 and the second rotating shaft 201 are driven to rotate the winding wheel 203.

[0057] Furthermore, when the elliptical wheel 206 rotates to a flat position, the driving pawl 2010 returns to the next tooth of the ratchet 202, and the braking pawl 8 brakes the ratchet 202 to prevent the ratchet 202 from rotating.

[0059] Step 4) When the wire is tightened, the elliptical wheel 206 rotates to drive the first gear 402 on the connecting rod 401 to rotate, and the second gear 405 is driven to rotate through the toothed belt 403.

[0061] Step 6) When the wire deviates in the wire limiting groove 4010 , the stripping blade 504 is pressed.

[0062] Step 7) Cut the wire from where the wire sheath is cut, peel and cut off part of the wire sheath, and then connect the wire to the wire pole.

[0063] The following three embodiments specifically illustrate the power construction tightening device and the use method thereof provided by the present invention from the three aspects of tightening wires, tidying wires and stripping wires.

[0064] Example 1

[0065] See also Figure 1An embodiment of the present invention provides a power construction tightening device, comprising a tightening device body 1, a tightening assembly 2, a first support plate 3, a wire tidying assembly 4 and a wire stripping assembly 5. The tightening device body 1 is provided with the tightening assembly 2, the first support plate 3 is symmetrically welded on the outer wall of one side of the tightening device body 1, the wire tidying assembly 4 is installed on one side of the first support plate 3, and the wire stripping assembly 5 is installed outside the tightening device body 1.

[0066] The tensioning assembly 2 includes a second rotating shaft 201, a ratchet 202, a winding wheel 203, a hook 204, a motor 205, an elliptical wheel 206, a third rotating shaft 207, a second spring 208, a rotating square rod 209 and a driving pawl 2010. The inner walls on both sides of the tensioning device body 1 are respectively rotatably connected to the second rotating shafts 201, and the winding wheel 203 is fixedly connected between the two second rotating shafts 201.

[0067] Among them, 3-5 hooks 204 are evenly arranged on the outer wall of one side of the winding wheel 203 along the axis direction of the winding wheel 203. As a specific embodiment of the present invention, 3-5 hooks 204 are fixedly connected to the outer wall of the winding wheel 203.

[0068] The second rotating shaft 201 is fixedly connected to the ratchet 202, and a driving pawl 2010 is arranged on the outer wall of one side of the ratchet 202. One end of the driving pawl 2010 is against the teeth of the ratchet 202, and the other end of the driving pawl 2010 is rotatably connected to one end of the rotating square rod 209. As a specific embodiment of the present invention, the connection between the driving pawl 2010 and the rotating square rod 209 is rotatably connected through a torsion spring, and the connection angle between the driving pawl 2010 and the rotating square rod 209 will change under the action of the torsion spring. That is, when a force is applied from the connection between the driving pawl 2010 and the rotating square rod 209, the angle between the driving pawl 2010 and the rotating square rod 209 will become, and when the force disappears, the angle between the driving pawl 2010 and the rotating square rod 209 will become smaller under the action of the torsion spring.

[0069] The other end of the rotating square rod 209 is fixedly connected to one end of the third rotating shaft 207, and the other end of the third rotating shaft 207 is rotatably connected to the inner wall of the end of the tensioner body 1. The rotating square rod 209 is connected to the inner wall of the tensioner body 1 through the second spring 20 arranged on the third rotating shaft 207. Specifically, the second spring 208 is sleeved on the third rotating shaft 207, one end of the second spring 208 is fixedly connected to the inner wall of the end of the tensioner body 1, and the other end of the second spring 208 is connected to the fixed connection between the rotating square rod 209 and the third rotating shaft 207. The second spring 208 is a torsion spring. When the rotating square rod 209 is twisted to a certain angle relative to the inner wall of the tensioner body 1, the rotating square rod 209 will rebound to the original angle under the torsion of the second spring 208.

[0070] In addition, the inner walls at both ends of the tensioner body 1 are rotatably connected to the first rotating shaft 6, and the other end of the first rotating shaft 6 is fixedly connected to the braking pawl 8, and the end of the braking pawl 8 abuts against the teeth on the outer wall of the ratchet 202. A first spring 7 is sleeved on the first rotating shaft 6, and one end of the first spring 7 is fixedly connected to the inner wall of the end of the tensioner body 1, and the other end of the first spring 7 is fixedly connected to the connection between the braking pawl 8 and the first rotating shaft 6. The first spring 7 is a torsion spring, which will reset the braking pawl 8 that has changed its angle relative to the inner wall of the end of the tensioner body 1. When the winding wheel 203 rotates with the second rotating shaft 201, the braking pawl 8 on the first rotating shaft 6 will move to the next tooth on the outer wall of the ratchet 202 under the torsion of the first spring 7.

[0071] The inner walls of both sides of the tensioner body 1 are respectively inlaid with motors 205 , one end of the output shaft of the motor 205 is fixedly connected with an elliptical wheel 206 , and the bottom end of the elliptical wheel 206 is closely connected to the outer wall of the driving pawl 2010 .

[0072] When the motor 205 is started, the motor 205 drives the elliptical wheel 206 to rotate. When the convex part of the elliptical wheel 206 contacts the driving pawl 2010, the driving pawl 2010 is squeezed, and the end of the driving pawl 2010 pushes the ratchet 202 to rotate through the teeth of the ratchet 202. When the elliptical wheel 206 rotates to a flat position, under the action of the second spring 208, the rotating square rod 209 on the third rotating shaft 207 is reset, and the angle between the driving pawl 2010 connected to the rotating square rod 209 through the torsion spring and the rotating square rod 209 becomes smaller under the action of the torsion spring, and the end of the driving pawl 2010 abuts against the next tooth of the ratchet 202. At the same time, the end of the braking pawl 8 abuts against the next tooth on the outer wall of the ratchet 202 to prevent the ratchet 202 from rotating when the rotating square rod 209 is reset.

[0073] A hanging plate 9 is fixedly connected to the top outer wall of the tensioner body 1 , and a handle 10 is fixedly connected to the top outer wall of the tensioner body 1 .

[0074] When it is necessary to tighten the wires, the construction personnel hang the electric power construction tightening device provided by the present invention on their bodies through the hanging plate 9, climb up the electric pole and stand at the high place of the electric pole, then take down the electric power construction tightening device hanging on their bodies through the handle 10, tie a knot at the end of a single wire, wrap it around the hook 204, then manually place the wire inside the wire limiting groove 4010, and vertically limit the wire through the wire limiting groove 4010 to prevent the wire from moving out of the wire limiting groove 4010.

[0075] The starting motor 205 rotates the elliptical wheel 206, and the driving pawl 2010 is squeezed through the convex part of the elliptical wheel 206, so that the third rotating shaft 207 on the rotating square rod 209 rotates along the tensioner body 1, and then the driving pawl 2010 squeezes the ratchet 202, so that the winding wheel 203 rotates along the second rotating shaft 201, and then under the action of the first spring 7, the braking pawl 8 on the first rotating shaft 6 moves to the next tooth, so as to tighten the wire. When the elliptical wheel 206 rotates to a flat position, under the action of the second spring 208, the rotating square rod 209 on the third rotating shaft 207 is reset, so that the driving pawl 2010 returns to the next tooth of the ratchet 202, and the ratchet 202 is braked by the braking pawl 8. Then repeat the above steps to make the reel 203 rotate continuously, so that the loose wires are tightened, thereby achieving the wire tightening operation on the loose wires, reducing manual auxiliary wire tightening, reducing the manual burden, and improving the wire tightening efficiency.

[0076] Example 2

[0077] See also Figure 1 , Figure 4 and Figure 5 The wire arrangement assembly 4 includes a connecting rod 401, a first gear 402, a toothed belt 403, a screw rod 404, a second gear 405, a guide rod 406, a moving block 407, a threaded hole 408, a guide hole 409 and a wire limiting groove 4010. The screw rod 404 is rotatably connected to the inner wall between the two first support plates 3, and the moving block 407 is threadedly connected to the screw rod 404.

[0078] Specifically, one end of the moving block 407 is provided with a threaded hole 408 whose inner diameter matches the outer diameter of the screw rod 404, and the moving block 407 is threadedly connected to the screw rod 404 through the threaded hole 408. When the screw rod 404 rotates, the moving block 407 moves on the screw rod 404 along the axis direction of the screw rod 404.

[0079] A guide rod 406 is fixedly connected to the inner wall between the two first support plates 3, and the other end of the moving block 407 is connected to the guide rod 406. Specifically, a guide hole 409 whose inner diameter matches the outer diameter of the guide rod 406 is provided at the other end of the moving block 407, and the other end of the moving block 407 is slidably connected to the guide rod 406 through the guide hole 409. When one end of the moving block 407 moves on the screw rod 404 along the axis direction of the screw rod 404, the other end of the moving block 407 will slide on the guide rod 406.

[0080] Among them, a wire limiting groove 4010 is opened at the top of the moving block 407.

[0081] In addition, the end of the screw rod 404 close to the inner wall of the first support plate 3 is fixedly connected to the second gear 405, the axis of the elliptical wheel 206 is fixedly connected to the connecting rod 401, the end of the connecting rod 401 is fixedly connected to the first gear 402, and the first gear 402 and the second gear 405 are connected by a toothed belt 403 meshing therewith.

[0082] When the wire is tightened, the rotating elliptical wheel 206 drives the pawl 2010, the ratchet 202 and the second rotating shaft 201 to cause the winding wheel 203 to rotate and tighten the wire. At the same time, the rotating elliptical wheel 206 also drives the first gear 402 on the connecting rod 401 to rotate. When the first gear 402 rotates, it drives the second gear 405 to rotate through the toothed belt 403. The rotation of the second gear 405 drives the screw rod 404 to rotate. When the screw rod 404 rotates, the moving block 407 screwed to the screw rod 404 through the threaded hole 408 moves along the axis of the screw rod 404. At the same time, the moving block 407 connected to the guide rod 406 through the guide hole 409 moves along the guide rod 406. When the moving block 407 moves, the wire limiting groove 4010 on the moving block 407 moves accordingly, and the wires in the wire limiting groove 4010 are offset by the movement of the wire limiting groove 4010 under the limiting action of the wire limiting groove 4010, so that the adjacent wires can be attached together when winding, so that the wires can be neatly arranged on the winding wheel 203, ensuring that the construction personnel can tighten more wires at one time in the air. And when tightening the wires, the wound wires can be regularized to avoid the accumulation of the wound wires, thereby improving the winding effect and winding efficiency.

The top of the peeling blade 504 extends out of the surface of the second support plate 501 from the light hole of the second support plate 501, and the bottom end of the peeling blade 504 is fixedly connected to the lifting rod 505. A lifting hole 503 through which the lower part of the lifting rod 505 passes is provided at the bottom of the storage box 502, and the bottom end of the lifting rod 505 passes through the lifting hole 503 and is fixedly connected to the connecting plate 506. A third spring 507 is fixedly connected between the upper surface of the connecting plate 506 and the outer wall of the bottom of the storage box 502, and the third spring 507 is sleeved on the outer wall of the lifting rod 505. There are four third springs 507, and the four third springs 507 are all compression springs. When the wire is pressed against the stripping blade 504, the stripping blade 504 will penetrate into the wire skin under the action of the third spring 507 on the bottom lifting rod 505, and the wire skin can be longitudinally split during the wire tension movement. When the wire is separated from the stripping blade 504, the stripping blade 504 can be reset and extended out of the second support plate 501 surface under the action of the third spring 507.

[0085] When the wire is rolled up and tightened by the winding wheel 203 under the cooperation of the pawl 2010 and the ratchet wheel 202, the wire is manually placed in the wire limiting groove 4010, so that the wire is vertically limited by the wire limiting groove 4010, and the wire is pressed against the stripping blade 504, so that the lifting rod 505 on the stripping blade 504 is lowered along the lifting hole 503 in the storage box 502, and at this time, the tip of the stripping blade 504 is inserted into the wire through the rebound force of the third spring 507. Since the wire moves when it is rolled up and tightened, the wire skin will be cut longitudinally, and then the tightened wire is manually cut off, and a part of the wire skin at the end is peeled off, and this part of the wire skin is manually cut off, and the exposed copper wire of the wire is installed on the wire pole. After the end of the wire is connected to the wire pole, the wire is separated from the stripping blade 504, and under the action of the rebound force of the third spring 507 on the connecting plate 506, the stripping blade 504 is reset and extends out of the surface of the second supporting plate 501. Therefore, when the wire is installed after being tightened, the wire can be stripped, avoiding manual stripping of the wire, and improving the stripping effect and efficiency of the wire.
