Problems solved by technology

[0002] In the maintenance of high-voltage transmission lines, there will be accidents to replace insulators. The insulators in high-voltage lines are large in size and weight, and they are high from the ground. One end of this insulator is installed on the fittings of the transmission line, and the other end is installed On the transmission tower, when replacing the insulator on the high-voltage line, it is necessary to place a leveling device under the insulator. The previous leveling device is a hard flat plate. Connected to the transmission tower, the cylindrical insulator that has just been dismantled has a certain momentum. If the staff does not control it well, the insulator may fall from the flat topping device, causing danger. In addition, this kind of topping device is A hard flat plate is inconvenient to carry in the field where some roads are not easy to walk. Finally, one end of this lifting device is lapped on the iron tower, and there is a situation where the lifting device slips from the iron tower.

Embodiment 1

[0013] Such as figure 1 with figure 2 Shown, a kind of portable support leveling device comprises a soft support leveling body 1, and described soft support leveling body is the canvas of a long direction, and two long sides of canvas are made into round sleeve, and support leveling body 1 Two hard rods 2 parallel to each other are arranged on the circular sleeves on both sides, and soft steel wires 3 are arranged on the lower surface of the flat body 1. Threads 4 are provided respectively, and the directions of the two threads 4 are opposite. The rod body between the thread 4 at one end of the hard rod 2 and the flat body 1 is a regular hexagon 5, and the thread 4 of the hard rod 1 is provided with a connecting body 6. The connecting body 6 is also provided with a fixed hook, which is movably connected with the connecting body 6 through bolts. The fixed hooks arranged on the connecting body are divided into two types. Connected screw rod, the other end is a horizontal hook...

Embodiment 2

[0015] In this embodiment, on the basis of the technical solution of Embodiment 1, safety ropes are also arranged on the hard rod. There are four safety ropes, and one end of the four safety ropes is fixedly connected with one end of the rod body. The other end is a lock, and the lock is fastened on the transmission tower and hardware during application, so that the connection safety factor of the device is higher.

Abstract

The invention belongs to the field of power transmission tools for power transmission systems, and in particular relates to a portable lifting device which is easy to carry, reliable in installation and suitable for dismantling various types of insulators. Parallel hard rods, soft steel wires are arranged on the lower surface of the flat body, the two ends of the soft steel wires are connected with the hard rods, and the rod bodies at both ends of the hard rods are respectively provided with threads, and the directions of the two threads are opposite, and the hard rods The rod body between the thread at one end and the flat body is a regular hexagon. The thread of the hard rod is provided with a connecting body, and the connecting body is also provided with a fixed hook. The fixed hook and the connecting body are connected by bolts. This device is easy to carry and It can cooperate with the disassembly of insulators of various shapes, and the soft steel wire rope also plays the role of supporting force, and the device is firmly fixed when in use.
