Description

Portable Multifunctional Transmission Line Power Outage Maintenance Auxiliary Tool

technical field

The utility model relates to an auxiliary tool for power failure inspection and maintenance of transmission lines, in particular to a portable multifunctional auxiliary tool for power failure inspection and maintenance of power transmission lines used for replacing tension insulators.

Background technique

At present, in the power outage replacement of tension insulators in the power supply department, two staff members on the tower usually cooperate. The staff all take the transfer rope and personal security line. Personal security line, and the transfer rope is hung on the appropriate position of the main iron of the cross arm with a pulley. Since the tension insulator is set horizontally, one of the staff generally moves slowly from the pole tower by riding on the insulator string The main body ends to the wire end; at the same time, another worker hangs the chain hoist (lever hoist) and the protective wire rope; the two workers cooperate with each other to hang the safety wire rope to prevent the wire from falling off, and hang the chain hoist on the tower body Between the terminal and the wire end, after carefully checking that the tools and appliances are suspended correctly to ensure safety, start to tighten the chain hoist until the insulator string is loose, and use the transfer rope to tie the knot at the appropriate position of the insulator string. Cooperate with putting down the old insulator string, and hang the new insulator string at the same time, connect the new insulator string with the suspension point of the cross arm, and insert the pin, then connect the connection point at the wire, and insert the pin; loosen the chain hoist to make the new The force on the insulator string is normal. After the operation is over, after checking that there is no error, the corresponding tools can be hoisted one by one. , The way of riding on the insulator string is very exhausting for the staff, and the constant shaking will make it difficult for the staff to find a balance point, and the burden is heavy, so the staff need a strong practical experience to complete it smoothly. In addition, some workers will use simple and unsafe tools such as bamboo poles to reach the wire ends of the insulators through simple binding, which also poses certain safety hazards.

Utility model content

Aiming at the problems existing in the replacement of tension insulators in the above-mentioned prior art, the utility model provides a portable multifunctional auxiliary tool for power outage inspection and maintenance of power transmission lines, which is simple in operation, high in safety, easy to carry, and saves energy.

The technical solution adopted for the problem to be solved by the utility model is: a portable multifunctional auxiliary tool for power failure maintenance of power transmission lines, including several connecting rods connected end to end, one end of the connecting rod is provided with a groove, and the other end is provided with a tongue , the connecting rod is symmetrically provided with a hook body connected to the cross arm and the wire, one end of the connecting rod is movably connected to one end of the supporting rod, the other end of the supporting rod is connected to a combined hoop, and the two sides of the connecting rod are provided with a walking frame. A moving slot is arranged in the walking frame, and a working foot buckle is clamped in the moving slot.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in combination with specific embodiments according to the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the portable multifunctional auxiliary tool for power failure maintenance of power transmission lines includes two connecting rods 6 connected end to end, one end of the connecting rods is provided with a groove 8, and the other end is provided with a tongue 9 , the groove and the tongue are movably connected by piercing bolts or butterfly bolts (not shown in the figure), and the connecting rod is symmetrically provided with a hook body 3 connected with the cross arm and the wire (the cross arm can use other fixing parts, the cross arm and wires are not shown), one end of the connecting rod is flexibly connected to one end of the supporting rod 2, and the other end of the supporting rod is connected to the combined hoop 1 (which is formed by four ring-shaped movable connections in sequence, which is convenient for assembly and carrying), and the two ends of the connecting rod The side is provided with a walking frame 5 (with a certain inclination angle with the connecting rod, which is convenient for the operator to step on), and a moving groove 7 is arranged in the walking frame, and a working foot buckle 4 is clamped in the moving groove (in order to prevent slippery, Anti-slip lines or anti-slip bumps should be set).

When it is necessary to work under the condition of 110kV voltage, there are 7-9 insulator sheets, and only one connecting pipe is required to meet the requirements. The two connecting rods are connected end to end, and the hook body in the middle part after the connection of the two connecting rods is removed, and the utility model is lifted to the cross arm by using the transfer rope, and the hook body at one end is hung on the wire connection end of the insulator, and the hook body at the other end is The hook body is fixed on the cross arm, and the combined hoop is fixed on the pole tower. The staff tie the safety rope and sit on one side of the connecting pole, step on the operation pedal, and hold the insulator string by hand (other methods can also be used). It can be easily moved to the wire connection end of the insulator, and other operators can complete the work of cleaning and replacing the insulator string.
