Description

Technical Field

[0001] The utility model relates to the technical field of high - voltage wire gluing, and particularly to a lifting device. Background Art

[0002] In the power transmission system, high - voltage transmission lines, as an important carrier of power transmission, their safe and stable operation is directly related to the social economic development and the daily life of residents. However, due to the wide range and complexity of high - voltage line laying, they inevitably pass through various terrains and landforms, including areas with dense population or frequent activities such as roads, residential areas, fish ponds, natural rivers, etc. Although this layout meets the power transmission requirements, it also brings potential electric shock risks. Especially in extreme weather conditions or accidents, such as typhoons, lightning strikes, vehicle collisions, etc., it may cause the high - voltage line to break and be grounded, thus seriously threatening the safety of surrounding residents and the ecological environment.

[0003] To prevent such electric shock accidents, especially for accidental contact with high - voltage lines caused by high - risk behaviors such as fishing and construction, a series of safety protection measures have been traditionally taken, such as setting warning signs and strengthening inspections. However, when facing unexpected situations caused by force majeure, the protection effect of these measures is often limited. Therefore, it is particularly important to develop a technical means that can directly improve the insulation performance of high - voltage lines.

[0004] In recent years, with the development of material science and technology, the application of insulating glue has gradually become one of the effective methods to improve the safety of high - voltage lines. By coating insulating glue on the outside of high - voltage lines, the insulation performance can be significantly improved, and the electric shock risk caused by the breakage of high - voltage lines can be reduced. However, since high - voltage lines are usually erected at high altitudes and are widely distributed, it is extremely difficult to directly apply glue to them, and special equipment is required to complete this task. These devices first need to be equipped with a lifting device to raise their own height to the height where the high - voltage lines are located. For this reason, we have proposed a lifting device suitable for raising the height of high - voltage wire gluing equipment. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a lifting device, which solves the problems raised in the above - mentioned background art.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A lifting device, comprising:

[0007] A hanger, which is hung outside the high - voltage line, and a main body housing is arranged below the hanger;

[0008] The traction mechanism is installed inside the main body housing. The driving end of the traction mechanism is connected to the hanger by a rope. The traction mechanism winds the rope, and under the reaction force, the height of the main body housing is increased.

[0009] Furthermore, the lifting device further includes:

[0010] A wire hole and a travel switch. The wire hole and the travel switch are both arranged at the top of the main body housing. The rope passes through the inside of the wire hole and enters the inside of the main body housing. When the maximum height is reached, the travel switch will abut against the hanger.

[0011] Furthermore, the lifting device further includes:

[0012] A guide wheel. The guide wheel is a supporting structure with the traction mechanism and is installed at the inner top end of the main body housing. The rope can pass through the inside of the guide wheel.

[0013] Furthermore, the hanger includes hooks symmetrically hung outside the high-voltage line. An upper mounting plate is commonly connected between the tops of the hooks, and a lower mounting plate is commonly connected between the bottoms.

[0014] Furthermore, a hook groove is reserved inside the hook, and the high-voltage line is located inside the hook groove. Rollers are symmetrically installed inside the upper mounting plate.

[0015] Furthermore, the traction mechanism includes a frame body installed at the bottom end inside the main body housing. A worm is rotatably connected to the bottom of the frame body, and a lifting drive motor is installed on the side. The drive end of the lifting drive motor is connected to the worm. A worm gear is rotatably connected to the top of the frame body. A winding disc is installed on the side of the worm gear. The worm gear meshes with the worm.

[0016] The present utility model provides a lifting device. Compared with the prior art, it has the following beneficial effects:

[0017] Through the combination of the exquisitely designed hanger and the traction mechanism, the lifting device realizes the efficient and stable lifting of the main body housing of the high-voltage line gluing equipment. Specifically, the hanger adopts a symmetric hanging method, ensuring the stable suspension of the device on the high-voltage line. At the same time, through the roller design, the friction between the high-voltage line and the hanger is reduced, protecting the high-voltage line from damage. The traction mechanism utilizes the worm and worm gear transmission principle and is driven by the lifting drive motor to achieve precise pulling of the rope, thereby smoothly lifting the main body housing to the height where the high-voltage line is located. In addition, through the design of the travel switch, when the main body housing is lifted to the predetermined height, the power supply can be automatically cut off to prevent over-lifting, further ensuring the reliability and stability of the equipment.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a lifting device, which is composed of a hanger 1, a main body housing 2, two sets of traction mechanisms 3, two ropes 4, two wire holes 5, two travel switches 6 and two guide wheels 7. When in use, it is necessary to first hang the hanger 1 on the high-voltage wire 8. The traction mechanism 3 is internally installed inside the main body housing 2. The traction end of the traction mechanism 3 is connected to the hanger 1 through two ropes 4. That is to say, it is necessary to lift the main body housing 2 to the height where the high-voltage wire 8 is located, and then the glue application structure (not shown in the figure) carried inside the main body housing 2 can be used to apply glue on the surface of the high-voltage wire 8. The two ropes 4 are introduced into the main body housing 2 through the two wire holes 5 and are connected to the drive end of the traction mechanism 3. When the height of the main body housing 2 is in place, the bottom end of the hanger 1 will squeeze the two travel switches 6, thereby disconnecting the power supply of the traction mechanism 3 and stopping the lifting. After the rope 4 enters the main body housing 2, the direction of the rope 4 is changed by the guide wheel 7, changing from the vertical direction to the horizontal direction;

[0025] Specifically, the fixture 1 includes hooks 11 symmetrically hung outside the high-voltage wire 8. An upper mounting plate 12 is commonly connected between the tops of the hooks 11, and a lower mounting plate 13 is commonly connected between the bottoms. A hook groove 14 is reserved inside the hooks 11. Rollers 15 are symmetrically installed inside the upper mounting plate 12. That is to say, after the fixture 1 is suspended, the high-voltage wire 8 is located inside the hook groove 14, and the upper surface of the high-voltage wire 8 will contact the rollers 15;

[0026] The traction mechanism 3 includes a frame body 31 installed at the bottom end inside the main body housing 2. A worm 32 is rotatably connected to the bottom of the frame body 31, and a lifting drive motor 33 is installed on the side. The drive end of the lifting drive motor 33 is connected to the worm 32. A worm gear 34 is rotatably connected to the top of the frame body 31. A wire winding disc 35 is installed on the side of the worm gear 34. The worm gear 34 meshes with the worm 32. The lifting drive motor 33 will drive the worm 32 to rotate. On the premise that the worm 32 meshes with the worm gear 34, the worm gear 34 is driven to rotate, thereby driving the wire winding disc 35 to rotate synchronously to pull the rope 4. Taking this as a power source, under the reaction force, the height where the main body housing 2 is located is lifted.
