Abstract
The utility model relates to a guiding structure for positioning three spring ends of a spring operating mechanism. The interior of a guiding box is provided with a switching-on spring and a transmission chain which can realize spring energy storage or energy release. Springs comprise an outer spring, an intermediate spring and an inner spring, and the springs are respectively sheathed with step surfaces which correspond to a front spring seat and a rear spring seat and are provided with three steps. Moreover, the front spring seat forms matched positioning with a positioning rod through a positioning surface for ensuring positioning stability. The structure ensures uniform gaps between the three springs. The operation of the springs is stable, the stress is uniform, and the friction resistance between the springs is eliminated. The energy of an energy storage spring can be increased, the switching-on speed is fast, and the switching-on power is increased. The utility model avoids the phenomenon that because the switching-on power is insufficient, a switching-on process can not be accomplished. In addition, the utility model also has the advantages of compact structure, convenient adjustment, etc.
Description
The utility model relates to the installing and locating mechanism of the energy-stored spring in the high-voltage switch gear spring operating mechanism.
Spring operating mechanism is with the energy storage by outer force compresses or extension spring of electric power or manpower, and releases energy by spring and to drive moving contact motion in the high-voltage switch gear, thereby is pressed on the fixed contact and making current loop.The speed that spring discharges and the big young pathbreaker of institute's work done directly influence closing speed, even the situation that can't close a floodgate occurs.Existing structure all uses a bar to drive spring energy-storage and release can, because an end of bar directly is connected on the connecting lever of rotation, bar is not only seesawed and swing is arranged, make spring stress be the non-rectilinear situation, when compression or when discharging slender type spring more than two, the friction condition of outer spring and outer guider and outer spring and inner spring can appear, and make spring must overcome the frictional resistance work done, have a strong impact on the energy of releasing of spring, cause occurring the combined floodgate merit and can not close a floodgate inadequately.
The purpose of this utility model be to overcome the defective of prior art and provide a kind of spring working stability, stressed evenly and can increase the energy-stored spring energy greatly, increase the spring operating mechanism three spring terminal positioning guiding structures of combined floodgate merit.
According to the foregoing invention purpose, embodiment of the present utility model is: by both sides side plate and last, following frid is fixed into the orientating box with square inner chamber, be provided with the spring of combined floodgate usefulness in the box and impel spring energy-storage or release can and the driving-chain by the transition of transition wheel guiding, its improvements are that this guide frame comprises front spring seat and the rear spring seat with three steps, before, be provided with the outer spring that is linked in respectively on the corresponding step surface between the rear spring seat, medi-spring, inner spring, and the front spring seat also is provided with two locating surfaces, and is installed in two reference columns on side plate location that matches.
The utility model is because forward and backward spring base has three ledge structures, make three springs be linked in mutually noninterfere on the corresponding step surface respectively, guarantee that gap each other is even, make the spring working stability, stressed even, eliminated the frictional resistance between spring and the spring, can increase the energy of energy-stored spring greatly, closing speed is fast, increases the combined floodgate merit, has avoided because of the not enough phenomenon of can't closing a floodgate that causes of combined floodgate merit; Two cambered surfaces of front spring seat and round steel near being connected, one helps self poisoning, two have increased lifting surface area, improve the stability of three springs; Except that this also has compact conformation, debugs advantages such as convenient.
Description of drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
To be described in detail again by above-mentioned accompanying drawing embodiment below.
Shown in Fig. 1-2, spring operating mechanism three spring terminal positioning guiding structures are by both sides side plate (16) and last, following frid (14), (15) be fixed into orientating box with screw with square inner chamber, be provided with the spring and the realization spring energy-storage of combined floodgate usefulness in the box or release the driving-chain that can and pass through the transition of transition wheel (1) guiding, the spring of combined floodgate usefulness is arranged between front spring seat (4) and the rear spring seat (12), before, rear spring seat has three steps, outer spring (5), medi-spring (6), inner spring (7) is linked in respectively on the step surface of three correspondences, guaranteed that the gap between each spring is even, the orientating box of square inner chamber has limited the degree of freedom of outer spring both direction, so can avoid spring to become curved when stressed.
In order to help the position stability of front spring seat (4), be provided with two locating surfaces at front spring seat end face, this locating surface be installed in two reference columns (3) on side plate location that matches, described locating surface can be the cambered surface that matches with reference column, also can with reference column near "
" profile, present embodiment is selected the globoidal structure locating surface for use, and reference column is good with round steel.This structure not only helps the location of spring base, has also increased its lifting surface area.
The compressed energy-storage of spring or release are realized by driving-chain, driving-chain comprises the leaf chain (2) by transition wheel (1) guiding, leaf chain is mutually hinged with screw rod group by connecting plate (8), bearing pin (9), this screw rod group is spirally connected by hexagonal screw rod (10) and conventional screw (11) and forms, and screw rod is threaded with the thread bush (13) that is enclosed within the recessed shoulder of rear spring seat (12) place.
External force makes transmission mechanism drive leaf chain along the transition wheel turning anticlockwise, makes the energy storage of length of spring compressed face, and Fig. 1 is the energy storage state, when energy-stored spring releases energy, drives the moving contact motion in the high-voltage switch gear, thereby is pressed on making current loop on the fixed contact.
