Abstract

The utility model discloses a device for adjusting an energy storage spring of a high-voltage circuit breaker. The device comprises a screw rod and a clamping plate. A clamping plate center hole is arranged in the center of the clamping plate. The inner wall of the clamping plate center hole is provided with an internal thread which is matched with the thread of the screw rod. The upper end of the screw rod penetrates through the clamping plate center hole and is in screw connection with the clamping plate. The screw rod, which is at the upper end of the clamping plate, is provided with a nut. The lower end of the screw rod is vertically provided with a fixation plate. The fixation plate is fixedly welded with the lower end of the screw rod. During using, firstly, the screw rod is enabled to pass through the inner side of a spring; then the clamping plate, a gasket and the nut are installed; and the two ends of the spring are fixed to the fixation plate and the clamping plate respectively. When the spring needs to be compressed, the nut is turned downwards so as to enable the nut to press the spring downwards; and when the spring needs to be extended, the nut is turned upwards so as to enable the nut to extend the spring upwards. The device for adjusting the energy storage spring of the high-voltage circuit breaker is simple in structure and convenient to operate, and is capable of compressing or extending the spring easily, so that the device for adjusting the energy storage spring of the high-voltage circuit breaker is labour-saving and time-saving, safe and convenient to use, and has excellent practical value.

Description

Primary cut-out energy-stored spring adjusting device

Technical field:

The utility model relates to a kind of spring regulating device, particularly relates to a kind of primary cut-out energy-stored spring adjusting device, belongs to electric power maintenance equipment technical field.

Background technology:

In electric power system, the use of energy-stored spring is very extensive, such as primary cut-out, divide-shut brake etc. all will use energy-stored spring, because the equipment such as primary cut-out, divide-shut brake in use often damage, needs often maintenance or changes.In maintenance or Renewal process, first need energy-stored spring to pull down, and energy-stored spring has in extended state, have in compressive state, there is certain potential energy, there is no special-purpose instrument, installation and removal energy-stored spring is difficult all, and easily accidentally injures attended operation personnel.

Utility model content:

Technical problem to be solved in the utility model is: a kind of convenient and strength-saving primary cut-out energy-stored spring adjusting device of energy-stored spring that mounts and dismounts is provided.

The utility model is that the technical scheme that technical solution problem is taked is:

A kind of primary cut-out energy-stored spring adjusting device, comprise leading screw and clamp, described clamp center is provided with clamp centre bore, on described clamp center bore inner wall, be provided with the internal thread matching with threads of lead screw, described leading screw upper end is provided with nut together with being screwed in clamp through clamp centre bore on the leading screw of clamp upper end; Described leading screw lower end is vertically installed with fixed head, and described fixed head and leading screw lower end are fixed and welded together.

Between described nut and clamp, be provided with pad.

Positive beneficial effect of the present utility model is as follows:

While 1, using the utility model, first leading screw is passed from spring inner side, then clamp, pad and nut are installed, both ends of the spring is separately fixed on fixed head and clamp.If when needing Compress Spring, nut is rotated down, make its downward Compress Spring; If when needing extension spring, nut is rotated up, make its extension spring that makes progress, compression and extension spring effect are very good.

2, the utility model is simple in structure, easy to operate, can be at an easy rate by spring-compressed or stretching, and time saving and energy saving, safe and convenient to use, there is good practical value.

3, the utility model has greatly facilitated attended operation personnel, for safety operation, safeguards sound assurance is provided, and has certain marketing prospect.

Accompanying drawing explanation:

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

Fig. 2 be in Fig. 1 clamp overlook enlarged drawing.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to Fig. 1 and Fig. 2, a kind of primary cut-out energy-stored spring adjusting device, comprise leading screw 2 and clamp 4, in the center of clamp 4, be provided with clamp centre bore 7, on clamp centre bore 7 inwalls, be provided with the internal thread that the screw thread with leading screw 2 matches, together with described leading screw 2 upper ends are screwed in clamp 4 through clamp centre bore 7, on the leading screw of clamp 4 upper ends, be provided with nut 3, between nut 3 and clamp 4, be provided with pad 1, in leading screw 2 lower ends, be vertically installed with fixed head 5, described fixed head 5 is fixed and welded together with leading screw 2 lower ends.

While using the utility model, first leading screw 2 is passed from spring 6 inner sides, then clamp 4, pad 1 and nut 3 are installed, spring 6 two ends are separately fixed on fixed head 5 and clamp 4.If when needing Compress Spring, nut 3 is rotated down, make its downward Compress Spring 6; If when needing extension spring 6, nut 3 is rotated up, makes its extension spring 6 that makes progress, the utility model is simple in structure, easy to operate, can at an easy rate spring 6 be compressed or be stretched, time saving and energy saving, safe and convenient to use, there is good practical value and marketing prospect.

The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, within all still belonging to the protection range of technical solutions of the utility model.
