Abstract
The present utility model relates to the switch cabinet interlocking device field, specifically to a mechanical interlocking device. The device comprises a bottom plate, an interlocking middle plate, an assembling panel, a spring guide rod, an interlocking spring and an interlocking shaft, a fixed pin is arranged on the interlocking middle plate, the lower end of the assembling panel is provided with a guide role matched with the pin shaft, the assembling panel can be moved in an upper and down way in relative to the interlocking middle plate. In the device, operation parts of an interlocking breaker and an isolation switch are adopted to realize locking requirements of successive movement, maloperation can be solved, equipment and personnel safety are guaranteed; a positioning member of the bottom plate of the device is changed into a round pin from a traditional long strip-shaped cardboard, the positioning effect is reinforced; a central line of guide hole and the assembling panel is changed into collineation from traditional eccentric arrangement, and the device is not easy to deform, is good in positioning and flexible to slide.
Description
Technical field
The utility model relates to the interlocking device of switch cabinet field, refers in particular to a kind of mechanical interlocks.
Background technology
Switch cubicle is for preventing misoperation, and decrease safent accident often arranges mechanical interlocks, but the interlock method imperfection of part mechanical interlocks, reliability and fail safe are low, and the misoperation phenomenon happens occasionally.Solve the misoperation problem, need the Interlock Reliability between assurance circuit breaker and the isolating switch.
The keeper of mechanical interlocks is the long strip type clamp that is embedded in lower door-plate location hole, and long strip type clamp intensity is low, and poor stability, locating effect are very limited.Assembling panel lower end be provided with interlock in the hinged pilot hole of plate, the center line eccentric setting of pilot hole and assembling panel, the panel bending strength is low, a little less than the bearing capacity, easy modification, and locating effect is poor, slides dumb.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides a kind of Interlock Reliability strong, can prevent misoperation, and not flexible type, the flexibly mechanical interlocks of having good positioning, slide.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mechanical interlocks, comprise plate in base plate, the interlocking, assembling panel, spring guide, interlocking spring and interlocking shaft, one fixing pin is arranged on the plate in the interlocking, and assembling panel lower end is provided with the pilot hole that is complementary with the pin axle, and plate moved up and down during the assembling panel can be interlocked relatively.
Assembling panel upper end central authorities are provided with isolating switch and earthed switch handle hole, and the lower end is provided with the interlocking bent plate of interlocked circuit breaker divide-shut brake button; Interlocking shaft is installed on the assembling panel, can move up and down perpendicular to the assembling panel; Plate upper end in the interlocking is fixed in the spring guide bottom, passes the pin-and-hole on the interlocking shaft, and split pin is inserted with restriction interlocking shaft stroke in the top.
When pressing the breaker closing button, the combined floodgate direction board drives the assembling panel and moves downward, and blocks isolating switch and earthed switch handle hole; Interlocking shaft moves downward with the assembling panel, and the interlocking spring compression is (breaker open operation) energy storage that resets of assembling panel.
When isolating switch and earthed switch handle hole were in open position, the assembling panel was displaced downwardly to minimum point, and the interlocking bent plate that the breaker closing knob is assembled panel blocks and can't press.
Base plate is provided with the location round pin, is complementary with the location hole of lower door-plate.
The center line of pilot hole and the centerline collineation that assembles panel.
The utility model is by interlocking isolating switch and circuit breaker, solve the misoperation problem, guaranteed equipment and personal security, and by the keeper of base plate and the pilot hole of assembling panel are improved, strengthen the locating effect of device, improved the flexibility that device slides.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the left view of Fig. 1.
Embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, hereby lift preferred embodiment and cooperate graphic being described in detail as follows:
See also Fig. 1 or shown in Figure 2, it is the structural representation of the preferred embodiment of the utility model, the utility model is relevant a kind of mechanical interlocks, comprise plate 2 in base plate 1, the interlocking, assembling panel 3, spring guide 4, interlocking spring 5 and interlocking shaft 6, one fixing pin is arranged on the plate 2 in the interlocking, assembling panel 3 lower ends are provided with the pilot hole 7 that is complementary with the pin axle, and plate 2 moved up and down during assembling panel 3 can be interlocked relatively.
Assembling panel 3 upper end central authorities are provided with isolating switch and earthed switch handle hole 8, and the lower end is provided with the interlocking bent plate 9 of interlocked circuit breaker divide-shut brake button; Interlocking shaft 6 is installed on the assembling panel, can move up and down perpendicular to the assembling panel; Plate upper end in the interlocking is fixed in spring guide 4 bottoms, passes the pin-and-hole on the interlocking shaft, and split pin is inserted with restriction interlocking shaft 6 strokes in the top.
When pressing the breaker closing button, the combined floodgate direction board drives assembling panel 3 and moves downward, and blocks isolating switch and earthed switch handle hole 8, and isolating switch can not be operated, and prevents that on-load from dividing, closing isolating switch.Interlocking shaft 6 moves downward with the assembling panel, and interlocking spring 5 compressions are (breaker open operation) energy storage that resets of assembling panel.
When isolating switch and earthed switch handle hole 8 were in open position, assembling panel 3 was displaced downwardly to minimum point, and the interlocking bent plate 9 that the breaker closing knob is assembled panel blocks and can't press, thereby prevented from closing circuit breaker by mistake, had guaranteed equipment and personal security.
The keeper of base plate changes location round pin 10 into by traditional long strip type clamp, has strengthened locating effect; Pilot hole 7 changes conllinear with the center line of assembling panel into by traditional eccentric setting, make device not flexible type, have good positioning, slide flexibly.
