Description
Technical field: the utility model relates to the high voltage electric power equip ment field, particularly a kind of primary cut-out piston rod guiding transmission device of hydraulic actuating mechanism.
Background technology: at present, in hydraulic operating mechanism of high voltage circuit breaker, how as shown in Figure 1 mechanism's piston rod guiding transmission device, its implementation is fit beneath one guide pad 2 of the contiguous block 3 that is connected with breaker body at piston rod 4, directive slide track 6 fixing on this guide pad 2 and the adpting flange 1 matches, and play the guiding role.The quadric chain that the transmission that moves to the auxiliary switch rotation of piston rod is formed by a plurality of parts such as connecting lever 8, connecting lever 10, connecting plate 7, double threaded screw 9, joint, splined shaft, pin 5 is realized.But this constitutional detail is more, and it is bigger to take up room, and is applicable to the occasion that structure space is looser.When circuit breaker hydraulic actuating mechanism overall volume less or space, breaker mechanism coupling part hour, this structure is just very inapplicable.
The utility model content: the utility model is more at existing circuit breaker hydraulic actuating mechanism piston rod guiding transmission structures part, the problem that structure space is bigger, a kind of hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission device is provided, this guiding transmission device number of spare parts is few, compact conformation takes up room and is applicable to hydraulic actuating mechanism and the less situation of breaker mechanism connection space that overall volume is less for a short time.
For reaching above purpose, the utility model takes following technical scheme to be achieved: hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission device, comprise piston rod, guide rail, adpting flange, bent plate and auxiliary switch, guide rail fixedly is assemblied in a side of adpting flange, bent plate fixedly is assemblied in the opposite side of adpting flange, auxiliary switch is assemblied on the bent plate, it is characterized in that: assembling one bracket on the described piston rod, the guide pad that protrude the bracket side is assemblied in the guide rail, the pin position hole that pin passes bracket is connected with breaker body, one end of connecting plate is connected with pin, and the other end of connecting plate is connected with the rotation axis of auxiliary switch.
The further technical scheme of the utility model is, described connecting plate one end is provided with U type groove, and cotter diameter passes this U type groove than the step axle of small end, and the connecting plate other end is provided with square opening, and the rotation axis of auxiliary switch passes this square opening.
The utility model is compared with existing hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission device, and have following beneficial effect: amount of parts is few, and processing is simple, saves cost and has reduced assembly difficulty; Compact conformation has been saved big quantity space, is easy to realize the operating mechanism miniaturization.
Description of drawings: accompanying drawing 1 is existing hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission structures schematic diagram.
Accompanying drawing 2 is a present utility model hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission structures end view.
Accompanying drawing 3 is a present utility model hydraulic operating mechanism of high voltage circuit breaker piston rod guiding transmission structures vertical view.
Among the figure: 1, adpting flange; 2, guide pad; 3, contiguous block; 4, piston rod, 5, pin; 6, guide rail; 7, connecting plate; 8, connecting lever; 9, double threaded screw; 10, connecting lever; 11, bent plate; 12, auxiliary switch; 13, adpting flange; 14, bracket; 15, connecting plate; 16, pin.
Embodiment: the utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As Fig. 2, shown in Figure 3, this transmission device comprises piston rod 4, guide rail 6, adpting flange 14, bent plate 11 and auxiliary switch 12, and guide rail 6 fixedly is assemblied in a side of adpting flange 14, and guide rail 6 passes the guide pad of bracket 14 sides processing; Bent plate 11 fixedly is assemblied in the another one side of adpting flange 13, and auxiliary switch 12 is assemblied on the bent plate 11; Bracket 14 is assemblied on the piston rod 4 by being threaded, the guide pad that protrude bracket 14 sides is assemblied in the guide rail 6, the pin position hole that pin 16 passes bracket 14 is connected with breaker body, pin 16 1 ends are processed as the U type groove that the less step axle of diameter passes connecting plate 15, the other end of connecting plate 15 is provided with square opening, and the rotation axis of auxiliary switch 12 passes this square opening.
Figure 3 shows that hydraulic operating mechanism of high voltage circuit breaker separating brake position, when the broken height voltage breaker closes a floodgate, mechanism's piston rod 4 moves from left to right, simultaneously bracket 14 moves right with piston rod, in the process of piston rod 4 and bracket 14 motions, the guide pad of bracket side slides on guide rail 6, and hydraulic mechanism piston rod 4 is play the guiding role.Pin 16 moves right simultaneously when bracket 14 moves right with hydraulic mechanism piston rod 4 combined floodgates, pass the microscler U type groove of connecting plate 15 because of the step axle of its end face processing, the rotating shaft that connecting plate lower end square groove passes auxiliary switch 12, it is that the axle center is made camber line from left to right and rotated with the square hole of its lower end that pin 16 can be stirred connecting plate 15 simultaneously, the rotating shaft of auxiliary switch 12 simultaneously clockwise rotates according to predetermined angle, so far, finish by a transmission process of the rotation that is linearly moved to auxiliary switch 12 of piston rod 4.The direction of motion of the rotating shaft of piston rod 4, bracket 14, connecting plate 15 and auxiliary switch 12 is all opposite with combined floodgate when the primary cut-out separating brake.
