Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer oil filling tool. Background Art

[0002] After installation or when the oil is lost during the use cycle, the oil-immersed transformer needs to be filled with oil. The oil filling pipe is usually connected to the bottom of the transformer, and in order to facilitate the opening and closing of the oil filling pipe, a connecting pipe is usually added to the bottom through a flange, and a control valve is set inside the connecting pipe. In order to facilitate oil filling, a docking flange will be left at the bottom of the connecting pipe for use by the oil filling tool. The oil delivery hose of the corresponding oil filling tool is also equipped with a matching flange for docking and oil delivery.

[0003] Although this method in the prior art can perform the oil filling process, it is inevitable that there are still some shortcomings in the actual use process. For example, the device lacks a suspension mechanism, so that the docking and lifting of the flange require multiple people to cooperate synchronously, which leads to the problem that the pre-oil filling process is more labor-intensive. In order to avoid this problem, a transformer oil filling tool is proposed to solve the existing problem. Utility Model Content

[0006] Preferably, the locking mechanism includes a limiting sliding frame, the limiting sliding frame is fixedly arranged inside the sliding plate, a latch plate with a handle is slidably connected inside the limiting sliding frame, a second return spring is fixedly connected between the latch plate with a handle and the limiting sliding frame, and two second return springs are symmetrically arranged front to back, and a slot for matching with the latch plate with a handle is opened at the top of the inner cavity of the slide plate.

[0007] Preferably, the bottom of the suspension plate is fixedly connected to a limiting sleeve, the interior of the limiting sleeve is slidably connected to a telescopic plate, and the bottom end of the telescopic plate is fixedly connected to the top of an adjacent slide plate, and a first return spring is fixedly connected between the telescopic plate and the limiting sleeve.

[0008] Preferably, a ball bearing is provided at the bottom of the suspension plate, and a plurality of ball bearings are provided.

[0009] Preferably, rubber strips are fixedly connected to opposite sides of the two suspension plates, and a plurality of rubber strips are provided on the same side.

[0010] Preferably, the two limiting sliding sleeves are fixedly connected to push-pull rods on opposite sides thereof. Beneficial Effects

[0011] The utility model provides a transformer oil filling tool. Compared with the existing technology, it has the following beneficial effects: the utility model slides and hangs on two sides of the second connecting flange, so that the second connecting flange is easy to hang the bottom of the first connecting flange, reducing the continuous support of manpower, and sets a locking mechanism between the hanging plate, the sliding plate, and the slide plate, so that the second connecting flange is used for the circumferential angle adjustment of the screw hole calibration, and can be locked by the locking mechanism and the above cooperation, so as to avoid the problem of the second connecting flange position changing due to the twisting and resetting of the oil delivery hose when the second connecting flange is circumferentially adjusted. Through the above cooperation, the device can be easy to operate by one person, reducing the use of excessive manpower. BRIEF DESCRIPTION OF THE DRAWINGS
