Background technology
At present, the operating mechanism of the breaker of Cubicle Gas-Insulated Switchgear both domestic and external is by connecting rod connecting lever
Parallelogram linkage is constituted, the transmission of moment of torsion is realized.Because operating mechanism volume is big, big length, poor sensitivity and stupid
Weight, can only put and set the lower section of the breaker cylinder of switchgear at this, so that this sets, switchgear volume is big, length is big, raw
Produce cost and increase, install and transport inconvenience, and make transmission link complexity, reliability and transmission efficiency it is poor.
The content of the invention
The purpose of this utility model is the transmission device that a kind of rotation of design becomes linear motion, simple with compact conformation,
Small volume, easy processing, low cost is installed and convenient transportation, and transmission link is simple, the good advantage of transmission efficiency.
For this purpose, the utility model is made up of operating mechanism and mechanism's connecting lever, the outer end of body connecting rod is located at breaker cylinder
In vitro, the outer end of body connecting rod is connected on base plate by joint and outer guide bearing axle with oblong slots and outer guide, is operated
Mechanism is located in the oblong slots of joint by the Roller Shaft on mechanism's connecting lever termination, and the inner of body connecting rod passes through interior guide bearing
Connect with the guide groove axle of the interior guide rail front end in breaker cylinder, the rear end connection interphase connecting rod of interior guide rail, under interphase connecting rod
Connect with the middle part axle of the first connecting lever and the second connecting lever in spacing distance on the support of the breaker cylinder at end, the upper end of the first connecting lever
Connect with the middle part axle of interphase connecting rod, the lower end of the first connecting lever connects with the lower end axle of an insulated tension pole, the upper end of the second connecting lever with
The rear end axle of interphase connecting rod connects, and the lower end of the second connecting lever connects with the lower end axle of other insulated tension pole.
The inner of described body connecting rod is connect with the breaker barrel wall in corresponding portion by oil sealing disk seal shaft.Described machine
Structure connecting lever rotate counterclockwise.
Said structure has reached the purpose of this utility model.
The utility model has compact conformation simple, small volume, easy processing, and low cost is installed and convenient transportation, transmission ring
Section is simple, the good advantage of transmission efficiency.Can widely use in the assembling of large electric equipment.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As illustrated, the transmission device that a kind of rotation becomes linear motion is made up of operating mechanism 2 and mechanism's connecting lever 1.This
The outer end of body connecting rod 7 is located at outside breaker cylinder 16, and the outer end of body connecting rod is by the joint 6 with oblong slots and outer guide 4
And the outer axle of guide bearing 3 is connected on base plate 15, bearing, outer guide bearing can be set in the base plate in joint portion corresponding with outer guide bearing
Axle is connected on the bearing of base plate.
Operating mechanism is located in the oblong slots of joint by the axle of roller 5 on mechanism's connecting lever termination.The inner of body connecting rod
Connect with the guide groove axle of the front end of interior guide rail 10 in breaker cylinder by interior guide bearing 9.The rear end connection phase of interior guide rail
Between connecting rod 12, in spacing distance and the first connecting lever 11 and the second connecting lever 13 on the support 14 of the breaker cylinder of interphase connecting rod lower end
Middle part axle connect.The upper end of the first connecting lever connects with the middle part axle of interphase connecting rod, the lower end of the first connecting lever and insulated tension pole
Lower end axle connects, and the first connecting lever controls the movement of this insulated tension pole（Complete divide-shut brake）.
The upper end of the second connecting lever connects with the rear end axle of interphase connecting rod, the lower end of the second connecting lever and other insulated tension pole 18
Lower end axle connects, and the second connecting lever controls the movement of other insulated tension pole.Support is held within the base plate in breaker cylinder.
The inner of described body connecting rod is connect with the breaker barrel wall in corresponding portion by the seal shaft of oil sealing disk 8.Described
Mechanism's connecting lever rotate counterclockwise.
When using, in the breaker cylinder of sealing SF6 gases 17 are filled.Motor passes through the transmission device lead agency connecting lever inverse time
Pin is rotated, and drives joint and body connecting rod to realize horizontal direct acting by the roller on mechanism's connecting lever.Oblong slots are provided with joint, are rolled
Son can be slided up and down in oblong slots, the downward shift amount of eliminating machine connecting lever rotation process.The two ends of body connecting rod equipped with it is interior,
Outer guide bearing.Inside and outside guide bearing can slide respectively in the guide groove of interior guide rail front end and in outer guide, can so ensure this
Body connecting rod realizes linear motion.Body connecting rod drives interphase connecting rod linear motion, interphase connecting rod to pass through first by interior guide rail again
Connecting lever and the second connecting lever drive each insulated tension pole motion, and then realize the breaking-closing operating of body.
Installation site is moved to the utility model the side of breaker cylinder by the lower end of breaker cylinder, can make breaker
Whole height is reduced, and is facilitated installation and is transported, and makes transmission link simple, improves reliability and transmission efficiency.
In a word, the utility model has compact conformation simple, small volume, easy processing, and low cost is installed and convenient transportation,
Transmission link is simple, the good advantage of transmission efficiency.Can promote the use of.
