Description

OLTC Overhaul Tool

technical field

The utility model relates to a maintenance tool for power supply, in particular to a maintenance tool for an on-load voltage regulating switch.

Background technique

The on-load tap changer is a tool that is often used in power supply, so its inspection and maintenance are usually things that need to be paid attention to. Now the maintenance of the on-load tap switch generally uses tools such as nylon ropes and levers to lift the on-load tap changer and then move it to the ground so that it can be overhauled. But this method is time-consuming and laborious, and there is no maintenance tool that can solve this problem now.

Contents of the invention

The purpose of the utility model is to provide an on-load tap changer maintenance tool, which can conveniently carry out maintenance on the on-load tap changer, saves manpower and material resources, and can be moved conveniently.

The technical scheme of the utility model is: an on-load tap changer maintenance tool, including a base, a telescopic rod is installed on the upper surface of the base, a cantilever is installed on the upper surface of the telescopic rod, and a pulley is provided on the lower surface of the cantilever. Universal wheels are fixed on the four corners of the lower surface, and telescopic supporting feet are arranged at the position close to the universal wheels on the lower surface of the base.

Preferably, the supporting foot is composed of a supporting rod and a bottom plate, the supporting rod is a telescopic sleeve structure, the supporting rod is provided with an adjusting nut, and the supporting rod is fixed on the bottom plate.

Preferably, screw holes are opened on the bottom plate.

Compared with the prior art, the utility model has the beneficial effect that the on-load tap changer can be directly hoisted due to the cantilever and the pulley. Universal wheels facilitate the movement of the base. The support feet hold the tool in place during servicing so that it does not become dislodged.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, an on-load tap changer maintenance tool includes a base 1, a telescopic rod 2 is installed on the upper surface of the base 1, a cantilever 3 is installed on the upper surface of the telescopic rod 2, and a pulley 4 is provided on the lower surface of the cantilever 3, Universal wheels 5 are fixed on the four corners of the lower surface of the base 1 , and telescopic support feet 6 are provided on the lower surface of the base 1 close to the universal wheels 5 . Preferably, the support foot 6 is composed of a support rod and a bottom plate, the support rod is a telescopic sleeve structure, the support rod is provided with an adjusting nut, and the support rod is fixed on the bottom plate; the bottom plate has a screw hole.

When using this maintenance tool, the steel rope is wound on the pulley 4 earlier, and one end of the steel rope is connected to the hook, and one end is connected to the power source. Then fix the OLTC on the hook. The power source moves, and the on-load tap changer is hoisted and placed on the base 1, which can be easily checked and repaired. After the overhaul is completed, the on-load tap changer can be restored directly.

Universal wheel 5 can facilitate the movement of this maintenance tool. The supporting legs 6 are usually gathered to facilitate the movement of the universal wheel 5 . Only when carrying out overhaul, support foot 6 is put down, in order to support, prevents from shifting because of the effect of universal wheel 5. Screws can also pass through the screw holes to fix the maintenance tool on the ground, which can be more stable.
