Description

Technical Field

[0001] The utility model relates to the technical field of pole relocation, in particular to a relocation device for transmission line poles. Background Art

[0002] The poles of transmission lines are structures used to support and fix conductors. They are mainly divided into several types, including straight poles, tension poles, and spanning poles. These poles play an important supporting and positioning role in the power system, ensuring the stable operation of transmission lines and the safe transmission of electric energy. Concrete poles are usually made of concrete and steel bars or steel wires. Generally, poles may be relocated after a long period of use. Relocation devices are widely used during pole relocation.

[0003] In the prior art, electric poles will age and break after long-term use, and in urban construction, some electric poles will hinder construction. At this time, the electric poles need to be relocated. Generally, when the electric poles are relocated, the overhead wires will be supported and limited. When the overhead wires are supported, they are often only simply limited and temporarily fixed by some tow rods or support rods. It is impossible to effectively and stably fix multiple overhead wires, thereby increasing the danger of the overhead wires when they are supported and limited. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6An expansion mechanism 2 is arranged on the upper side of the base 1, and a plurality of expansion mechanisms 2 are arranged. A limiting mechanism 4 is arranged on the upper side of the plurality of expansion mechanisms 2. The expansion mechanism 2 can support and expand the limiting mechanism 4, thereby realizing the displacement of the limiting mechanism 4, and the limiting mechanism 4 can be used to stably and effectively fix, limit and support the overhead wires, thereby increasing the stability of the overhead wires when the poles are relocated. At the same time, due to the arrangement of the expansion mechanism 2, the limiting mechanism 4 can change the position more simply and smoothly when supporting and fixing the overhead wires at different positions, thereby increasing the range and applicability of the limiting mechanism 4 when in use;

[0025] The expansion mechanism 2 includes a hollow block 21, a rotating rod 22, a worm 23, a worm wheel 24, a connecting block 25, a bidirectional screw 26 and a limiting rod 27. The hollow block 21 is arranged on the upper side of the base 1, the rotating rod 22 is rotatably connected to the inner side of the hollow block 21, the upper end of the rotating rod 22 passes through the hollow block 21, the worm 23 is fixedly connected to the outer side of the rotating rod 22, the connecting block 25 is fixedly connected to the inside of the hollow block 21, the bidirectional screw 26 and the limiting rod 27 are both arranged inside the connecting block 25, the hollow block 21 can install and fix the worm 23 through the rotating rod 22, and at the same time, when the rotating rod 22 rotates, it can smoothly drive the worm 23 to rotate together, the connecting block 25 can connect the bidirectional screw 26 with the limiting rod 27, and there is a gap between the connecting block 25 and the bidirectional screw 26 It is a rotational connection, and the connecting block 25 and the limiting rod 27 are fixedly connected. The worm wheel 24 is fixedly connected to the outer side of the bidirectional screw 26. The worm wheel 24 and the worm 23 are meshed with each other. The outer side of the bidirectional screw 26 is threadedly connected with a moving block 3, and two moving blocks 3 are provided. The two moving blocks 3 are both slidably connected to the outer side of the limiting rod 27. The bidirectional screw 26 can also be installed on the worm wheel 24. The meshing between the worm 23 and the worm wheel 24 enables the bidirectional screw 26 to be smoothly driven to rotate through the worm wheel 24 when the worm 23 rotates. At the same time, the threads on both sides of the bidirectional screw 26 are opposite, and the limiting rod 27 can limit the moving block 3. This enables the two moving blocks 3 to be smoothly driven to move in opposite directions when the bidirectional screw 26 rotates.

[0026] Reference Figure 3 and Figure 6The limiting mechanism 4 includes a first connecting plate 41, a fixed plate 42, a first spring 43, a first clamping arc block 44, a movable plate 45, a second spring 46 and a second clamping arc block 47. The first connecting plate 41 is arranged on the upper side of the movable block 3, the fixed plate 42 is fixedly connected to the upper side of the first connecting plate 41, the first spring 43 is fixedly connected to one side of the fixed plate 42, the first clamping arc block 44 is fixedly connected to one end of the first spring 43, the movable plate 45 is arranged on the upper side of the first connecting plate 41, the second spring 46 is fixedly connected to one side of the movable plate 45, and the second clamping arc block 47 is fixedly connected to one end of the second spring 46 More specifically, the first connecting plate 41 can connect the first spring 43 and the first clamping arc block 44 through the fixed plate 42, and the second spring 46 and the second clamping arc block 47 can be installed through the movable plate 45. The first clamping arc block 44 and the second clamping arc block 47 can be effectively and stably clamped on the outside of the overhead wire through the elasticity of the first spring 43 and the second spring 46, thereby realizing the limitation of the overhead wire, and because the movable block 3 can be moved by the rotation of the bidirectional screw 26, the position of the first clamping arc block 44 and the second clamping arc block 47 can be adjusted and displaced as needed.

[0027] Reference Figure 6 , one side of the fixed plate 42 is rotatably connected with a one-way screw 5, and the movable plate 45 is threadedly connected to the outer side of the one-way screw 5. More specifically, after the first clamping arc block 44 and the second clamping arc block 47 are clamped on the outer side of the overhead wire by the first spring 43 and the second spring 46, the staff can rotate the one-way screw 5, and the one-way screw 5 will smoothly drive the movable plate 45, the second spring 46 and the second clamping arc block 47 to move to the side close to the first clamping arc block 44, and when the movable plate 45 moves, The first spring 43 and the second spring 46 will be squeezed. The greater the force with which the first spring 43 and the second spring 46 are squeezed, the more elastic force the first spring 43 and the second spring 46 themselves will release through elasticity, thereby increasing the clamping force of the first clamping arc block 44 and the second clamping arc block 47 on the overhead wire, thereby further increasing the stability of the overhead wire when clamped by the first clamping arc block 44 and the second clamping arc block 47. At the same time, the first clamping arc block 44 and the second clamping arc block 47 can be made of insulating materials.

[0028] Reference Figure 3 and Figure 4The inside of the hollow block 21 is fixedly connected with a first reinforcement block 61 and a second reinforcement block 62. The first reinforcement block 61 is arranged on the outside of the bidirectional screw 26, and the bidirectional screw 26 is rotatably connected to the first reinforcement block 61. The second reinforcement block 62 is fixedly connected to the outside of the limit rod 27. More specifically, the first reinforcement block 61 can increase the stability of the bidirectional screw 26 during use and rotation through the connection between itself and the hollow block 21, while the second reinforcement block 62 can increase the stability of the second reinforcement block 62 during use through the connection between itself and the hollow block 21.

[0029] Reference Figure 5 A card slot 7 is provided on the upper side of the movable block 3, and a card block 10 is fixedly connected to the lower side of the first connecting plate 41. The card block 10 is movably connected to the inside of the card slot 7, and there are multiple card slots 7. More specifically, the arrangement of the card slot 7 and the card block 10 enables the staff to simply and easily connect the limiting mechanism 4 to the upper side of the movable block 3, and because there are multiple card blocks 10, the staff can increase or decrease the number of the limiting mechanisms 4 according to the actual situation, so as to further meet the actual needs.

[0030] Reference Figure 1 and Figure 4 A fixed hollow rod 8 is fixedly connected to the outer side of the rotating rod 22, and a second connecting plate 9 is arranged between the multiple expansion mechanisms 2. More specifically, the fixed hollow rod 8 can facilitate the staff to rotate the rotating rod 22, so that the staff can hold and rotate the rotating rod 22 more conveniently, and the setting of the second connecting plate 9 can support and connect the multiple expansion mechanisms 2, so that the use of the multiple expansion mechanisms 2 can be sufficiently stable.

[0031] Working method: When the device is in use, the staff can connect the base 1 to the external equipment by bolts, and then adjust the position of the moving block 3 according to the position of the overhead wire. When adjusting, the staff can rotate the fixed hollow rod 8, and the fixed hollow rod 8 will drive the worm wheel 24 to rotate through the rotating rod 22 and the worm 23. When the worm wheel 24 rotates, it will smoothly drive the bidirectional screw 26 to rotate together. At this time, due to the limitation of the moving block 3 by the limit rod 27 and the opposite threads on both sides of the bidirectional screw 26 itself, the two moving blocks 3 can move smoothly in opposite directions. When the moving block 3 moves, it can effectively drive the limiting mechanism 4 to move together, thereby realizing the change of the position of the limiting mechanism 4.

[0032] When the limiting mechanism 4 is moved to the required position, the staff can clamp the first clamping arc block 44 and the second clamping arc block 47 on the outside of the overhead wire, and rotate the one-way screw 5 after clamping. The one-way screw 5 will push the second clamping arc block 47 to move to the side close to the fixed plate 42 through the movable plate 45, and the second clamping arc block 47 will cooperate with the first clamping arc block 44 to increase the clamping force of the overhead wire when moving, thereby realizing effective and stable limiting of the overhead wire.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
