Background technology

The sulphur hexafluoride gas insulated metal enclosed swit chgear is called for short GIS.Chinese invention patent application " electric operating mechanism of circuit-breaker ", open day is on August 27th, 2008, publication number is CN101252046, announced a kind of electric operating mechanism of circuit-breaker, comprise power transmission shaft, place that be used for connecting and gear, the colour code indicating dial that is fixed in the power transmission shaft upper end that drive by reducing gear of the end on the lower side of power transmission shaft, the cam and that is fixed in the power transmission shaft lower end to be fixed in rolling member on the cam with the reducing gear transmission, described cam the position on the power transmission shaft occupy gear above; Described gear hub setting is in offering a rolling member groove at least on the power transmission shaft and on gear, an end of described rolling member probes in the rolling member groove and with cam to be fixed, and the other end then stretches out in the rolling member groove.This motor-operating mechanism complex structure, transmission efficiency is low.

The utility model content

The technical problems to be solved in the utility model is, a kind of electric spring operation machine of simple in structure, reliable in action is provided.

For solving above technical problem, a kind of electric spring operation machine provided by the utility model, comprise cabinet and be installed in the interior transmission mechanism of cabinet, reducing gear, the connecting rod of interlocking gear and driving switch divide-shut brake, motor by reduction gearing with transmission of power to worm shaft, worm and wheel on the worm shaft is meshed, worm gear set is contained on the worm-wheel shaft, also be set with connecting lever on the worm-wheel shaft and be installed with and dial plate and crank, crank and described connecting rod are hinged, the circumference of worm gear is provided with the breach curved surface, position relative with connecting lever on the cabinet is hinged with spring shaft, the free end of spring shaft is connected with the push rod perpendicular to the spring shaft axis, the push rod middle part is hinged on the connecting lever, and an end is hinged on to be dialled on the plate, and the other end contacts with the breach curved surface of worm gear.

As improvement of the present utility model, described interlocking gear comprises manual interlock and mechanical interlocking device, and manually interlock and mechanical interlocking device are separately positioned on the two ends of worm shaft.

With respect to prior art, the utility model has been obtained following beneficial effect: worm gear set is contained on the worm-wheel shaft, worm-wheel shaft did not change when worm gear rotated, dialling plate and crank is fixedly mounted on the worm-wheel shaft, both and worm-wheel shaft rotate synchronously, motor drives worm shaft and then drives worm gear when rotating by reduction gearing, breach curved surface on the worm gear promotes push rod and spring shaft rotates, spring quilt on the spring shaft is compressed energy-storage progressively, when the axis of spring shaft was positioned on the line of worm gear central point and spring shaft and cabinet pin joint, it is maximum that the decrement of spring reaches, and crosses this point, spring is released, when spring discharged, the push rod of spring shaft end promoted to dial plate and rotates, and dialled the moving worm-wheel shaft rotation of strip, worm-wheel shaft drives the crank rotation again, and the crank drive link is split to close and carried out separating brake or closing operation.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of the utility model electric spring operation machine.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the utility model transmission mechanism schematic diagram.

Fig. 4 is the right view of Fig. 3.

Among the figure: 1 cabinet, 2 buffers, 3 manual interlocks, 4 worm screws, 5 mechanical interlocking devices, 6 spring shafts, 7 motors, 8 pinions, 9 gear wheels, 10 worm gears, 11 connecting levers, 12 worm-wheel shafts, 13 push rods, the 14 groups of plates, 15 cranks, 16 connecting rods.

Embodiment

As shown in Figures 1 and 2, electric spring operation machine of the present utility model, comprise cabinet 1 and be installed in the connecting rod of transmission mechanism, reducing gear, interlocking gear and driving switch divide-shut brake in the cabinet 1, cabinet 1 is a Welding Structure, postwelding is processed each associated orifices, guarantee each fitted position, cabinet 1 left and right and positive capping plate.Manually interlock 3 and mechanical interlocking device 5 are separately positioned on the two ends of worm shaft.

As shown in Figures 3 and 4, on motor 7 output shafts pinion 8 is installed, gear wheel 9 and pinion 8 engagements, gear wheel 9 is installed on the worm shaft, worm screw 4 on the worm shaft is meshed with worm gear 10, and worm gear 10 and connecting lever 11 are sleeved on the worm-wheel shaft 12 and can rotate around worm-wheel shaft, dials plate 14 and crank 15 and is fixedly mounted on the worm-wheel shaft 12, crank 15 is hinged with connecting rod 16, and the wobble drive switch of connecting rod 16 is made separating brake or feed motion.The circumference of worm gear 10 is provided with the breach curved surface, position relative with connecting lever 11 on the cabinet 1 is hinged with spring shaft 6, the free end of spring shaft 6 is connected with the push rod 13 perpendicular to the spring shaft axis, push rod 13 middle parts are hinged on the connecting lever 11, one end is hinged on to be dialled on the plate 14, and the other end contacts with the breach curved surface of worm gear 10.When push rod 13 during to the direction motion of spring shaft 6 and cabinet 1 pin joint, spring is compressed.

Motor 7 energisings are rotated, and slowing down by pinion 8, gear wheel 9 drives worm shaft, worm shaft and worm gear 10 double reduction transmissions, and worm gear 10, connecting lever 11 rotate around worm-wheel shaft 12, and the breach curved surface of worm gear 10 promotes push rod 13 and spring shaft 6 rotates the energy storage of spring pressurized.When turning to the off-position, spring freely discharges, and promotes to dial plate 14, dials plate 14 and drives worm-wheel shaft 12 rotations, drives simultaneously and is fixed on crank 15 on the worm-wheel shaft, and crank 15 links to each other with Switch main body by connecting rod 16, finishes the branch closing operation of switch.In minute closing operation latter stage,, add buffer 2 to absorb impact energy in order to reduce impact to product.
