Its function is to maintain the tension of the power line during the wire laying process, ensure that the power line is correctly laid along the predetermined path, and avoid wire slack or deviation from the track caused by insufficient tension. This device usually includes a bottom plate, a top plate, a connecting rod, a wire tightening mechanism (such as rollers and chutes), etc. Through the cooperation of these components, effective tensioning and control of the power line can be achieved.

When in use, through the design of the connecting arc plate and the like, the power line can be prevented from rotating during wire laying, the outer protective skin of the power line is not damaged, and the service life of the power line is extended. However, during the power line tensioning process, due to the hard friction between the power line and the connecting arc plate, the outer skin of the power line will still be damaged. This device has no insurance measure for power line loosening, and there is also a problem of inconvenient disassembly and assembly of the power line reel.

[0004] Therefore, we provide a power line tensioning device for power line laying to solve the above problems. Content of the Utility Model

[0005] This application provides a power line tensioning device for power line laying, which solves the problems of no insurance measure for power line loosening and inconvenient replacement of the power line reel.

[0006] This application provides a power line tensioning device for power line laying, including a base and a wire pulling mechanism. The wire pulling mechanism is arranged on the left side of the top end of the base;

[0007] The wire pulling mechanism includes an eccentric component arranged at the left edge of the top of the base. A wire arranging component is installed near the middle position on the left side of the top of the base, and a roller component is installed inside the wire arranging component.

[0008] Preferably, the eccentric component includes an eccentric bracket welded to the left edge of the top of the base. An eccentric shaft is welded to the upper side of the eccentric bracket. An eccentric wheel is installed on the outer side of the eccentric shaft. A limiting column is welded to the top of the eccentric bracket outside the eccentric wheel.

[0009] Preferably, two groups of the eccentric shaft, the eccentric wheel and the limiting column are symmetrically arranged before and after with respect to the horizontal center line of the eccentric bracket.

[0010] Preferably, an outer frame is welded near the middle position on the left side of the top of the base. A chute is provided on the upper side of the outer frame. A clamping block is installed inside the chute. A handle is welded to the upper side of the clamping block. A hanging frame is welded to the bottom end of the clamping block.

[0011] Preferably, the roller component includes a hanging ear arranged at the bottom end inside the hanging frame. A spring is installed on the outer side of the hanging ear. A wheel frame is installed on the upper side of the spring. A groove roller is installed inside the wheel frame. One group of the roller components is provided at the left edge of the bottom end inside the hanging frame and at the right edge of the top end inside the hanging frame respectively.

[0012] Preferably, a wire coiling mechanism is arranged on the right side of the top of the base. The wire coiling mechanism includes a wire coiling component arranged at the right edge of the top of the base. A combined wheel component is installed near the middle position on the right side of the top of the base. The wire coiling component includes a wire wheel bracket welded to the right edge of the top of the base. An axle bracket is provided at the rear side of the wire wheel bracket. An axle hole is provided at the front side of the wire wheel bracket. An axle seat is installed inside the axle hole. A square axle is installed inside the axle seat. A first rotating shaft is welded to the rear side of the square axle. A wire coiling wheel is welded to the outer side of the first rotating shaft. A wire coiling column is welded to the outer side of the wire coiling wheel. A driven gear is installed at the front end outside the axle seat.

[0013] Preferably, the combined wheel component includes a support plate arranged near the middle position on the right side of the top of the base. A ratchet wheel is installed on the front side of the support plate. A driving gear is welded to the front side of the ratchet wheel. A crank is welded to the front side of the driving gear. A second rotating shaft is welded to the front top of the support plate. A catch is installed on the outer side of the second rotating shaft. The ratchet wheel and the support plate are movably connected. The ratchet wheel and the catch are connected by a card slot. The driving gear and the driven gear are meshed with each other.

[0014] As can be seen from the above technical solution, the present application provides a power line tensioning device for power line erection. When in use, first pass the power line through the hole between the two eccentric wheels, then through the groove rollers not on the same horizontal line, tie the power line to the wire spool column, rotate the crank counterclockwise, so that the ratchet rotates counterclockwise, driving the driving gear to rotate counterclockwise, and the driven gear rotates clockwise through the meshing action with the driving gear, the wire spool rotates clockwise, and the wire spool column drives the power line to wind around the outside of the wire spool. Drag the handle to move the hanging frame back and forth along the chute to make the wire arrangement more compact, avoiding the winding of the power line. Every time the ratchet rotates a certain angle, the catch automatically hooks onto the teeth of the ratchet under the action of gravity, realizing the limiting function of the ratchet.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. Through the setting of the wire pulling mechanism, when tensioning the power line, the power line passes through the hole between the two eccentric wheels and is tightened to the right. When the power line loosens to the left, the two eccentric wheels rotate towards the horizontal center line, locking the power line by relying on friction. When the power line reaches between the two groove rollers, since the two groove rollers are not on the same horizontal plane, the power line can be straightened and sorted out, avoiding messy wire winding. When arranging the wires, the hanging frame can be moved back and forth along the chute through the handle to make the wire arrangement more compact, facilitating subsequent operations;

[0017] 2. Through the setting of the wire spooling mechanism, when tensioning the power line, the power line can be wound around the outside of the wire spool through the wire spool column. The wire spool column is convenient for winding the power line around the smooth wire spool. The shaft bracket can not only make the wire spool rotate stably, but also facilitate the disassembly and assembly of the wire spool. The ratchet and the driving gear are designed as one body, enabling the ratchet and the driving gear to rotate simultaneously, facilitating the restriction of the rotation of the driving gear by restricting the rotation of the ratchet. The catch automatically hooks onto the teeth of the ratchet under the action of gravity, restricting the rotation of the ratchet and the driving gear, realizing the automatic clamping function. The tooth ratio of the driving gear and the driven gear is relatively small, making it more labor-saving to carry out the power line tensioning work.

[0018] In summary, the present application can realize the automatic locking of the power line after loosening through the eccentric component, avoiding the possible loosening of the power line without insurance measures, and solving the problem of inconvenient replacement of the power line reel.

[0025] In order to enable those skilled in the art of this technology to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] See Figures 1-4 , a power line tensioning device for power line laying, including a base 1 and a wire pulling mechanism 2, and the wire pulling mechanism 2 is arranged on the left side of the top end of the base 1;

[0027] The wire pulling mechanism 2 includes an eccentric component 21 arranged at the left edge of the top end of the base 1, a wire arranging component 22 is installed near the middle position on the left side of the top end of the base 1, and a roller assembly 23 is installed inside the wire arranging component 22.

[0028] In the present utility model, the eccentric component 21 includes an eccentric bracket 211 welded to the left edge of the top end of the base 1, an eccentric shaft 212 is welded to the upper side of the eccentric bracket 211, an eccentric wheel 213 is installed outside the eccentric shaft 212, and a limit post 214 is welded to the top end of the eccentric bracket 211 outside the eccentric wheel 213. When tensioning the power line, the power line can pass through between the eccentric wheels 213, and the limit post 214 can ensure that the eccentric wheel 213 can only rotate within a certain range.

[0029] In this utility model, there are two sets of the eccentric shaft 212, the eccentric wheel 213 and the limit post 214 symmetrically arranged before and after with respect to the horizontal center line of the eccentric bracket 211. When tightening the power line, the power line can pass through the hole between the two eccentric wheels 213 and be tightened to the right. However, when the power line loosens to the left, the two eccentric wheels 213 rotate towards the horizontal center line and lock the power line by relying on the friction force.

[0030] In this utility model, on the top left side of the base 1 near the middle position, an outer frame 221 is welded. A chute 222 is opened on the upper side of the outer frame 221. A clamping block 223 is installed inside the chute 222. A handle 224 is welded on the upper side of the clamping block 223. A hanging frame 225 is welded at the bottom end of the clamping block 223. When arranging the wires, the hanging frame 225 can be moved back and forth along the chute 222 through the handle 224, making the wire arrangement more compact, avoiding the entanglement of the power line, and facilitating the operation.

[0031] In this utility model, the roller assembly 23 includes a hanging ear 231 arranged at the bottom end inside the hanging frame 225. A spring 232 is installed on the outer side of the hanging ear 231. A wheel frame 233 is installed on the upper side of the spring 232. A groove roller 234 is installed inside the wheel frame 233. One set of the roller assembly 23 is arranged at each of the left edge at the bottom end inside the hanging frame 225 and the right edge at the top end inside the hanging frame 225. After the power line passes through the hole between the two eccentric wheels 213, since the two groove rollers 234 are not at the same horizontal plane, the power line can be straightened and arranged neatly by the two groove rollers 234.

[0032] In some embodiments, a wire coiling mechanism 3 is arranged on the top right side of the base 1. The wire coiling mechanism 3 includes a wire coiling assembly 31 arranged at the right edge at the top of the base 1. A combined wheel assembly 32 is installed on the top right side of the base 1 near the middle position. The wire coiling assembly 31 includes a wire wheel bracket 311 welded at the right edge at the top of the base 1. An axle bracket 312 is opened at the rear side of the wire wheel bracket 311. An axle hole 313 is opened at the front side of the wire wheel bracket 311. An axle seat 314 is installed inside the axle hole 313. A square shaft 315 is installed inside the axle seat 314. A first rotating shaft 316 is welded at the rear side of the square shaft 315. A wire coiling wheel 317 is welded on the outer side of the first rotating shaft 316. A wire coiling post 318 is welded on the outer side of the wire coiling wheel 317. A driven gear 319 is installed at the front end of the outer side of the axle seat 314. When tightening the power line, the power line can be wound around the outer side of the wire coiling wheel 317 through the wire coiling post 318. The wire coiling post 318 is convenient for winding the power line around the smooth wire coiling wheel 317. The axle bracket 312 can not only make the wire coiling wheel 317 rotate stably, but also facilitate the disassembly and assembly of the wire coiling wheel 317.

[0033] In some embodiments, the combined wheel assembly 32 includes a support plate 321 disposed at a position near the middle on the right side of the top end of the base 1. A ratchet wheel 322 is installed on the front side of the support plate 321. A driving gear 323 is welded to the front side of the ratchet wheel 322. A crank 324 is welded to the front side of the driving gear 323. A second rotating shaft 325 is welded to the top end of the front side of the support plate 321. A catch 326 is installed on the outer side of the second rotating shaft 325. The ratchet wheel 322 and the driving gear 323 are designed as a whole, which can make the ratchet wheel 322 and the driving gear 323 rotate simultaneously, facilitating the restriction of the rotation of the driving gear 323 by restricting the rotation of the ratchet wheel 322. The ratchet wheel 322 is movably connected to the support plate 321, and the ratchet wheel 322 and the catch 326 are connected by a card slot. The driving gear 323 and the driven gear 319 mesh with each other. The catch 326 automatically hooks onto the teeth of the ratchet wheel 322 under the action of gravity, restricting the rotation of the ratchet wheel 322 and the driving gear 323. The tooth number ratio of the driving gear 323 and the driven gear 319 is small, which can make the power line tensioning work more labor-saving.

[0034] As can be seen from the above technical solutions, during use, first, the eccentric wheels 213 are turned to both sides. The power line passes through the hole positions between the two eccentric wheels 213 and then through the groove rollers 234 that are not on the same horizontal line. The power line is tied to the wire coiling post 318. The crank 324 is rotated counterclockwise, causing the ratchet wheel 322 to rotate counterclockwise, driving the driving gear 323 to rotate counterclockwise. The driven gear 319 rotates clockwise through the meshing action with the driving gear 323, and the wire coiling wheel 317 rotates clockwise. The wire coiling post 318 drives the power line to wind around the outer side of the wire coiling wheel 317. The handle 224 is dragged to move the hanging frame 225 back and forth along the sliding groove 222 to make the wire arrangement more compact and avoid the winding of the power line. Every time the ratchet wheel 322 rotates a certain angle, the catch 326 automatically hooks onto the teeth of the ratchet wheel 322 under the action of gravity, realizing the limiting effect on the ratchet wheel 322. Thus, the use process of such a power line tensioning device for power line laying is completed.
