Description
Technical field
The present invention relates to a kind of switch cubicle, is a kind of switch cubicle of operated according to mechanical programs specifically.
Background technology
At present, people are equipped with up and down two isolating switches, the high-tension switch cabinet of two earthed switches and vacuum circuit-breaker up and down what be commercially available, generally operate by five cover operating mechanisms, the priority operating sequence of five cover operating mechanisms must be observed strict regulation, if branch, the closing operation of the isolating switch of switch cubicle, earthed switch and vacuum circuit-breaker are wrong, can cause serious accident.So switch cubicle must design one and overlap very complicated mechanical interlock, this complicated machinery interlock complex operation and possible misoperation, thus cause immeasurable loss.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, safe in utilization, dependable performance, easy to operate switch cubicle.
The present invention is achieved through the following technical solutions.
A kind of switch cubicle by Mechanically programm's control, comprise cabinet, vacuum circuit-breaker, be installed in the three-station of cabinet top and the bottom, the operating mechanism and the position-limit mechanism of the mechanical movement of control three-station, it is characterized in that: the operating mechanism of described control three-station mechanical movement comprises the bevel-gear sett pair, a driving shaft, the pivoted arm of two band pins, two sheaves, driven gear and driving shaft in the bevel gear pair are coupling, two pivoted arms that have a pin are separately positioned on the two ends of driving shaft, sheave is installed in the outside of pivoted arm, sheave is provided with groove, and the pin on the pivoted arm of driving shaft two ends is inserted in the groove of sheave; Described sheave is connected with connecting lever in the three-station up and down by connecting rod.
Groove in the described sheave is a m shape groove, and the end face of sheave is with guiding projection and locate recessed; Described two sheaves are arranged on the two ends of driving shaft with rightabout up and down.
Described position-limit mechanism is installed in cabinet the place ahead.
But described position-limit mechanism comprises the junction panel of the baffle plate move left and right that is arranged on the driving shaft, and junction panel is provided with lockhole and projection; Described baffle plate semicircular in shape and staggered being distributed on the driving shaft.
The present invention compared with prior art has the following advantages.
The operating mechanism of control three-station of the present invention mechanical movement mainly is made of bevel gear pair and Geneva mechanism, when needs operation controlling organization, handle is put into the insertion mouth, rotary handle drives the driven wheel rotation in the bevel gear pair, driven wheel drives driven gear and rotates, and then the drive shaft turns that is coupling of driving and driven gear.Thereby the pivoted arm at driving shaft two ends also rotates, because the pin on the pivoted arm is inserted in the groove of sheave, swings up and down so drive sheave.Pivoted arm phase phasic difference 180 degree at driving shaft two ends are so driving shaft can make the sheave at two ends, the left and right sides alternately swing up and down in rotation process, and then the three-station up and down that driving links to each other with sheave is in strict accordance with the program alternating movement.

Embodiment
Below in conjunction with accompanying drawing switch cubicle of the present invention is described in further detail.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, switch cubicle by Mechanically programm's control described in the invention mainly by cabinet, vacuum circuit-breaker, be installed in the three-station of cabinet top and the bottom and the operating mechanism of control three-station mechanical movement.The operating mechanism of control three-station mechanical movement comprises bevel gear pair 1, driving shaft 2, the pivoted arm 3 and sheave 4 that have pin 31, bevel gear pair 1 is made up of with driven gear 12 intermeshing driven wheel 11, driven gear 12 is coupling with driving shaft 2, each the reverse installation one of the two ends of driving shaft 2 has the pivoted arm 3 of pin 31, sheave 4 is installed in the outside of pivoted arm 3, sheave 4 is provided with m shape groove, pin 31 on the driving shaft 2 two ends pivoted arms 3 is inserted in the groove 41 of sheave 4, m shape groove 41 is made of two sections straight-line grooves and two sections arc grooves, also has recessed 43 of guiding projection 42 and location on the end face of sheave 4.Sheave 4 is connected with connecting lever in the three-station by connecting rod 5, and wherein a sheave links to each other with last three-station, and another sheave links to each other with following three-station.Can drive sheave 4 by pin 31 when driving shaft 2 rotates swings up and down, instructions for use according to switch cubicle, three-station palpus follow procedure alternating movement up and down, promptly when the sheave 4 that links to each other with last three-station was swung, the sheave 4 that links to each other with following three-station remained static; When the sheave 4 that links to each other with following three-station was kept in motion, the sheave 4 that links to each other with last three-station remained static, successively action again and again.When the pin on the pivoted arm 3 31 is positioned at the straight flange groove of sheave m shape groove 41, along with must driving sheave 4, pin 31 rotations swing up and down, when pin 31 is positioned at the arc groove of sheave m shape groove 41, the axis coinciding of the center of circle of arc groove and driving shaft 2, so, pin 31 rotates around the center of circle of arc groove, and sheave 4 is in motionless state.Two straight flange grooves of m shape groove 41 can make three-position switch finish from being grounding to disconnection again to the process of closing a floodgate, two arc grooves of m shape groove 41 mainly make three-station remain static, promptly when left side pin 31 is positioned at the straight flange groove of sheave m shape groove 41, the right pin 31 is positioned at the arc groove of sheave m shape groove 41, at this moment, sheave 4 motions on the left side, sheave 4 transfixions on the right; When the right pin 31 was positioned at the straight flange groove of sheave m shape groove 41, left side pin 31 was positioned at the arc groove of sheave m shape groove 41, at this moment, sheave 4 motions on the right, sheave 4 transfixions on the left side, thus satisfy the instructions for use of three-station up and down.So, handle is put into inserted mouth in use, rotate respective angles and can finish the alternating movement of three-station up and down.Cabinet the place ahead is equipped with position-limit mechanism, but position-limit mechanism mainly is made of the junction panel 7 that is arranged on baffle plate 6 and move left and right on the driving shaft 2, baffle plate 6 semicirculars in shape, staggered being distributed on the driving shaft 2, also be provided with lockhole 71 and projection on the junction panel 7, be used to limit the operation follow procedure carries out step by step and with the interlocking of vacuum circuit-breaker, cabinet door.As can be seen from the above description, switch cubicle of the present invention is only by a cover controlling organization, can finish six alternating movements of two three-stations up and down, and vacuum circuit-breaker and the requirement of cabinet door follow procedure are operated, avoid people in the Operation and maintenance process, accident to occur.
