[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model embodiment provides a wire lifting device, please refer to Figures 1-4 , including winch 10, winch line 20, fixed pulley 30, line hook 40 and high tower 50, high tower 50 is located between two adjacent low tower 60, fixed pulley 30 is rotatably connected on high tower 50, winch line 20 is used to connect winch 10 and line hook 40 and is wound on fixed pulley 30, line hook 40 is used to pull wire 1.

[0027] Use the wire lifting device of this embodiment, first erect high tower 50 between two adjacent low tower 60, winch line 20 is wound on fixed pulley 30 and is connected with winch 10. The other end of winch line 20 can be connected on line hook 40, and line hook 40 hooks wire 1 between two low tower 60. Starting winch 10 can make wire 1 lift until being fixed on high tower 50. Implement the wire lifting device in the utility model, and the purpose of lifting old wire 1 to super high tower can be realized without helicopter.

[0028] In an embodiment, please refer to Figure 1 , further comprising movable pulley 60, movable pulley 60 is rotatably connected on line hook 40, one end of winch line 20 is connected on high tower 50 and is threaded in movable pulley 60.

[0029] Fixed pulley 30 can change the direction of force, movable pulley 60 can reduce the load of winch 10, generally, fixed pulley 30 and movable pulley 60 are combined into a pulley block.

[0030] It should be noted that a plurality of fixed pulleys 30 and a plurality of movable pulleys 60 can be set according to actual needs. In theory, each movable pulley 60 can reduce the load of the winch 10 by half.

[0031] In an embodiment, referring to Figures 2-4 Further comprising a tensioner 70, the tensioner 70 is arranged at both ends of the wire 1 and pulls the wire 1.

[0032] The tensioner 70 is a very important mechanical equipment in power grid construction, mainly used for power line tension stringing and high-altitude cableway erection work. It is used in cooperation with the traction machine to provide the necessary traction and tension for the wire 1, so that the wire 1 can be erected according to the predetermined path.

[0033] The working principle of the tensioner 70 is based on the fact that when an object is subjected to tension, there is a mutual traction force perpendicular to the contact surface between the two adjacent parts. This force is called tension. The tensioner 70 controls this tension to ensure that the wire 1 is not damaged due to excessive stretching or relaxation during erection.

[0034] In practical applications, the tensioner 70 can be hydraulically driven or electrically driven. The traditional hydraulic tensioner 70 controls tension through a hydraulic system, while the new electric tensioner 70 uses a motor and an intelligent control system to achieve more precise tension control. During operation, the electric tensioner 70 uses the motor to generate electricity, which can efficiently recover and store the traction kinetic energy. Not only does it not need fuel, but it also does not need external charging, achieving an integrated cycle of energy generation, storage, and use. The sensitivity of this electric tensioner 70 in tension control is improved to milliseconds, and the tension control deviation is reduced to 1%, greatly improving construction efficiency and having the ability to adapt to complex environments such as high cold and high heat.

[0035] In an embodiment, the high tower 50 includes a first tower 510 and a second tower 520, the first tower 510 is higher than the second tower 520, and the tensioner 70 is on the side of the second tower 520 away from the first tower 510.

[0036] In the field of power grid construction, the height of the tower can be between dozens of meters and more than a hundred meters. The tower spanning the viaduct requires very high, about a hundred meters high, while the conventional tower (i.e. low tower 60) is only a few tens of meters high. Therefore, directly erecting the wire 1 between the low tower 60 and the super-high tower 50 will cause the wire 1 to be excessively inclined. The first tower 510 is higher than the second tower 520, and the first tower 510 generally spans both sides of the viaduct, while the second tower 520 is between the first tower 510 and the conventional low tower 60.

[0037] In an embodiment, a low tower 60 is further arranged between the second tower 520 and the tensioner 70, and the wire 1 is sequentially erected on the low tower 60, the second tower 520, and the second tower 520.

[0038] The second tower 520 is lower than the first tower 510, but higher than the low tower 60, and most of the conductor 1 is finally erected on the low tower 60. For the tension machine 70, the degree of bending of the conductor 1 should be as low as possible to avoid the conductor 1 being broken or damaged due to excessive local stress.

[0039] In an embodiment, the number of the first tower 510 and the second tower 520 is at least two, and the first tower 510 is arranged in the middle of the second tower 520.

[0040] The number of the first tower 510 is two, and a building such as a viaduct is arranged between the two first towers 510, and the second towers 520 on both sides of the first tower 510 can play a role in transitioning the conductor 1. Finally, the conductor 1 near the non-viaduct is still erected on the low tower 60.

[0041] In an embodiment, a traction rope 80 and a connecting assembly 90 are further included, one end of the traction rope 80 is connected to the tension machine 70, the other end is connected to the connecting assembly 90, and one end of the conductor 1 is also connected to the connecting assembly.

[0042] Because the original length of the conductor 1 is not long enough, the conductor 1 cannot enter the tension machine 70 on both sides, so the traction rope 80 needs to be arranged as a supplement to the length of the old conductor 1. The traction rope 80 is usually a 15cm diameter anti-twist steel wire rope.

[0043] The connecting assembly 90 plays a role in connecting the conductor 1 and the traction rope 80 together. The common conductor 1 connecting assembly 90:

[0044] 1, terminal: the terminal is a kind of accessory product used to realize electrical connection, which is usually composed of non-metallic support parts and metal connecting parts, which can be WUK terminal, stretch type terminal series, plug-in type terminal series, etc.

[0045] 2, connector: connector, also known as pin connector, is a kind of component that electronic engineering and technical personnel often contact. It is mainly used for the circuit connection between cables and cables, cables and equipment in electrical and electronic equipment, and can realize the transmission of signal and electric energy (power).

[0046] 3, cable joint: the cable joint is a device used to connect the conductor, insulation, shielding layer and protection layer of the cable and the cable, so as to make the cable line continuous.

[0047] 4, crimp tube: when connecting aluminum core conductor, crimp tube is used for crimping to ensure the firm connection between two conductors 1.

[0048] 5. Wire connector: The wire connector can realize high-reliability electrical connection, and because it can be completely operated manually without the aid of special tools, the installation process is very fast and efficient.

[0049] In an embodiment, referring to Figure 5 The connection assembly 90 includes a strain steel anchor 910 for connecting the wire 1 and a tension shackle 920 for connecting the traction rope 80.

[0050] The strain steel anchor 910 is an important component in the power transmission line for fixing the wire 1 and bearing the tension of the wire 1. It is usually used in combination with steel-cored aluminum stranded wire, combined with the wire 1 through hydraulic pressure connection, forming part of the strain clamp. The main function of the strain steel anchor 910 is to bear the mechanical load of the wire 1, ensuring the stability and safety of the wire 1. The strain steel anchor 910, together with the aluminum pipe, fixes the steel-cored aluminum stranded wire through layered pressure connection, in which the steel anchor and the steel core are pressure connected to bear the mechanical load of the wire 1; the aluminum pipe and the aluminum stranded wire are pressure connected to realize current transmission. The strain steel anchor 910 has the advantage of large holding force on the wire 1 or optical cable, and uniform stress distribution.

[0051] The tension shackle 920, also known as a shackle, is a strong metal connector used for lifting operations. It has a U-shaped design and is equipped with a pin closure mechanism for safe connection. The shackle is made of high-strength alloy steel, with excellent durability and load-bearing capacity. They are commonly used in construction, maritime and industrial environments for lifting heavy objects. The use of shackles requires that they not exceed the rated load, and the body and pin should be inspected before use to ensure that there is no serious wear, deformation and fatigue cracks. The D-shaped shackle is a special type used in power construction, with small size, light weight, large load capacity and high safety factor.

[0052] In an embodiment, the traction rope 80 has a rotator 100 at the end away from the tensioner 70.

[0053] The function of the rotator 100 is mainly to prevent the wire 1 from being twisted and damaged.

[0054] In an embodiment, the specification of the tension shackle 920 is 5t.

[0055] 5t means that the maximum tensile strength of the tension shackle 920 is 5 tons.

[0056] Finally, it should be noted that only the first tower 510 can be used in the high tower 50, and the second tower 520 can be used according to actual conditions, mainly according to the height of the wire 1 to be lifted on site to determine.

[0057] Furthermore, the high towers 50 can span one or more low towers 60, again primarily as a function of the width of the building to be spanned. If the building is too wide, it is likely that there will be two low towers 60 between two high towers 50.
