Abstract
The utility model relates to a tool for adjusting the energy of a switching-closing spring of a spring mechanism, and the tool comprises a cylinder, a spring disposed inside the cylinder, and a compression bolt which is used for pressing the spring. The cylinder is a hollow cavity with one end opened. A slidable slide cover is disposed inside the cylinder. A graduated ruler is fixed on the slide cover. An end part of the graduated ruler extends out from the sealed end of the cylinder. The spring is disposed outside the graduated ruler between the slide cover and the sealed end of the cylinder. An end face, which is towards the opened end of the cylinder, of the slide cover is provided with a compression cushion block. The opened end of the cylinder is covered by an end cover. The middle part of the end cover is rotatingly connected with the compression bolt. The inner end of the compression bolt extends into the cylinder to butt against the compression cushion block. The outer edge of the end cover is located outside the cylinder. The middle part of the cylinder is provided with a connection part. The outer edge is connected with the connection part via fixing bolts. During stretching adjustment of the spring, the tool provided by the utility model is easy and rapid for operation, is safe and reliable, effectively stops the spring from releasing suddenly, avoids related mechanical accidents, improves work efficiency, and guarantees work quality on site.
Description
Technical field
The utility model relates to a kind of spring mechanism divide-shut brake spring energy adjusting tool.
Background technology
Operating mechanism is the actuating executive system of circuit breaker, is the core kinetic energy auxiliary products of circuit breaker.And spring operating mechanism is to utilize the spring of energy storage to realize the breaking-closing operating of circuit breaker for power, and spring energy-storage is to rely on motor to provide energy to realize.Spring operating mechanism is widely used in Xinjiang region with advantages such as its superior performance, safe and reliable, easy to maintenance and long service life.But; the spring mechanism of the domestic and international production of using at present is varied; different manufacturers, different model, complex structure, processing technology require there are differences, transmission link is more; often can break down; the spring energy-storage situation not in place that particularly causes due to mechanical breakdown happens occasionally; in case this type of defective occurs, must carry out detailed inspection to mechanism's mechanical transmission component and energy-stored spring parts.checking process in the past is the release that the maintenance pin that only is equipped with producer stops spring energy, and this process can not guarantee in the situation that spring energy keeps sincere son to lose efficacy, sudden action occurs in mechanism, thereby increased the danger the when maintainer works, and work as dividing, switching-in spring carries out adjustment process wastes time and energy, one group of this pattern spring mechanism divides, the switching-in spring adjustment need expend 24 hours/3 people's time at least, cause the equipment interruption duration long, the equipment dependability index is low, manpower labour intensity is large, the unfavorable factors such as mechanical wounding risk height.
Summary of the invention
It is flexible that the purpose of this utility model is to propose a kind of regulating spring freely, guarantees to overhaul the spring mechanism divide-shut brake spring energy adjusting tool that carries out smoothly.
The purpose of this utility model is achieved in that spring mechanism divide-shut brake spring energy adjusting tool, it comprises cylindrical shell, be installed in the spring in cylindrical shell, compression bolt in order to pressuring spring, cylindrical shell is the uncovered cavity body of an end, is placed with slidably slip lid within it, is fixed with ruler on slip lid, the ruler end is stretched out by the cylindrical shell blind end, and the ruler between slip lid and cylindrical shell blind end is outside equipped with spring.Be provided with the compression cushion block on the end face of cylindrical shell opening end at slip lid.Cylindrical shell opening end place is stamped end cap, and end cap middle part is connected with compression bolt, and cylindrical shell is stretched in compression bolt the inner, contacts with the compression cushion block.The end cap outer is positioned at outside cylindrical shell, is provided with connecting portion at cylindrical shell middle part, is connected by set bolt between outer and connecting portion.
The utility model is simple in structure, operates simple and easy, quick, saving manpower when adjusting telescopic spring, and is safe and reliable, effectively prevented the spring sudden outburst, avoided the associated mechanical accident, improved operating efficiency, guaranteed on-the-spot work quality.
Description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is spring mechanism divide-shut brake spring energy adjusting tool structural representation.
Legend: 1, ruler, 2, spring, 3, cylindrical shell, 4, slip lid, 5, the compression cushion block, 6, compression bolt, 7, set bolt, 8, end cap.
Embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete execution mode according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, spring mechanism divide-shut brake spring energy adjusting tool comprises cylindrical shell 3, is installed in the spring 2 in cylindrical shell 3, in order to the compression bolt 6 of pressuring spring 2.Cylindrical shell 3 is the uncovered cavity body of an end, is placed with slidably slip lid 4 within it, is fixed with ruler 1 on slip lid 4, and ruler 1 end is stretched out by cylindrical shell 3 blind ends, and the ruler 1 between slip lid 4 and cylindrical shell 3 blind ends is outside equipped with spring 2.Be provided with compression cushion block 5 on the end face of cylindrical shell 3 opening ends at slip lid 4.Cylindrical shell 3 opening end places are stamped end cap 8, and end cap 8 middle parts are connected with compression bolt 6, and cylindrical shell 3 is stretched in compression bolt 6 the inners, contacts with compression cushion block 5.End cap 8 outers are positioned at outside cylindrical shell 3, are provided with connecting portion at cylindrical shell 3 middle parts, are connected by set bolt 7 between outer and connecting portion.
In use, turn compression bolt 6, by stretching of compression bolt 6, push compression cushion block 5, thereby push slip lid 4, and then spring 2 is compressed.Ruler 1 is along with the slip of slip lid 4 at cylindrical shell 3, and the length of its exposure end also changes thereupon, by the scale on ruler, can accurately judge the compression degree of spring 2.By set bolt 7, that end cap 8 is fixing, can prevent spring 2 sudden outbursts and eject outside cylindrical shell 3.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
