Description

Sliding flat ladder for repairing wires in live work

technical field

The utility model relates to a sliding flat ladder for repairing wires in live work for maintenance of high-voltage transmission lines.

Background technique

At present, the maintenance of high-voltage transmission line conductors is generally carried out by hanging ladders, and the repair of conductors often requires two people to complete the operation at the same time, and the operating position needs to be moved during the operation. The problem of using suspended ladders for wire repair is that the cooperation effect between the two ladders is not good, and the position is inconvenient to move, the operation labor intensity is high, and the work efficiency is low.

Contents of the invention

The purpose of this utility model is to solve the above problems and provide a sliding flat ladder suitable for two-person cooperative operation, which is convenient to move, can effectively reduce the labor intensity of work, and improve work efficiency.

The technical solution to achieve the above purpose is: a sliding flat ladder for repairing wires in live work, which has a flat ladder with hanging hooks at both ends; the hanging hook has vertical double hook bodies, and a pair of horizontal The shaft is equipped with a pair of rollers, and a horizontal safety baffle is installed under each roller through a pair of screws. The lower end of the double hook body is hinged with a U-shaped hanging plate, and the lower end of the U-shaped hanging plate is hingedly connected with the hook connecting shaft installed at the end of the flat ladder; It is composed of several cross bars between two main bars.

The technical solution of the utility model also includes: the main rod forming the flat ladder is arranged in a segmented structure, and connected with the fixing bolts of the main rod through the connecting sleeve and the wearing sleeve placed at the connecting end.

The utility model adopts a suspended sliding flat ladder to form a wire repairing operation platform, which is especially suitable for two-person cooperative operation, and the flat ladder can be moved by the assembled rollers, which can effectively reduce the labor intensity of live wire repairing operations, improve work efficiency, and ensure Safety and quality of repair work.

Detailed ways

The specific embodiment of the utility model will be described in conjunction with the accompanying drawings.

As accompanying drawing 1, this live work repair wire sliding flat ladder is made of the flat ladder 2 that two ends are provided with suspension hook 1.

As accompanying drawing 2, its flat ladder 2 is made up of two parallel main rods 3 and several cross bars 4 that wear between the two main rods. The main rod 3 can be arranged in two sections, and the connecting sleeve 5 placed at the joint end and the threaded sleeve are connected with the fixing bolt 6 of the main rod to form a segmented flat ladder structure, so as to facilitate the transportation of the flat ladder and carry. During the concrete implementation of the utility model, according to needs, its flat ladder also can be set to the three-section joint structure.

As shown in accompanying drawing 3, the hanging hook 1 of this sliding flat ladder has a vertical double hook body 7, and a pair of rollers 9 are assembled in the hook body through a pair of transverse shafts 8, and a horizontal hook is assembled with a pair of screws 10 below each roller. The safety baffle plate 11 is hinged with a U-shaped hanging plate 12 through the vertical bolts at the lower end of the double hook body, and the lower end of the U-shaped hanging plate is hinged with the hook connecting shaft 13 that is installed on the end of the flat ladder.

As accompanying drawing 4, the screw connection holes configured with the screw 10 on its safety baffle 11 are respectively arranged as L-shaped elongated holes 14 and opening elongated holes 15, which are used to open the safety baffle and connect the wires and the rollers 9 before the wires cooperate. After the rollers are matched, the safety baffle is fixed in place to prevent the wires from coming out of the hooks and ensure the reliable and safe suspension of the sliding flat ladder.
