Abstract
The utility model belongs to the device of the high voltage transmission and distribution, relating to a static contact covering-curtain door opening device for a movable switch cabinet. The static contact covering-curtain door opening device is respectively provided with a horizontal push plate at the both sides of the car frame of the carriage of a breaker. Simultaneously, the static contact covering-curtain door opening device for the movable switch cabinet is respectively provided with a pair of a driving gear and a driving rack mutually matched at the both sides of the cabinet body of the movable switch cabinet; the external circumferential position of the driving gear is provided with a roller matched with the horizontal push plate; the driving rack is at the horizontal position, and the front end is connected with a transmission rod at the vertical position through a transmission mechanism. The upper end and the lower end of the transmission rod are respectively matched to transmit with an upper spiral arm shaft and a lower spiral arm shaft through a rack-gear transmission mechanism, and upper and lower spiral arms on the upper and lower spiral arm shafts are respectively hinged with an upper curtain door and a lower curtain door. The front ends of the upper and lower curtain doors are respectively limited in upper and lower slide rails in the vertical direction. The utility model which has the advantages of reasonable structure, high transmission efficiency, light transmission force and accurate and reliable action can achieve the self-locking at the opening positions of the curtain doors.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of withdraw-type switch cabinet fixed contact cover door opening device.
Background technology
Withdraw-type switch cabinet (as the armored withdraw type ac metal closing switch gear), its circuit breaker dolly is in propulsive mechanism pushes cabinet the time, needing a cover fixed contact cover door opening device opens the fixed contact cover door automatically, so that the moving contact on the circuit breaker dolly inserts the stationary contact head-shield smoothly, peg graft with fixed contact.The opening and closing device of existing withdraw-type switch cabinet, some is one-sided driving, reliability is relatively poor; The product that some bilaterals drive then exists lower shutter can not self-locking after opening, to up and down between the contact spacing require big, influence defective such as cabinet layout size.
Summary of the invention
Technical problem to be solved in the utility model is, but the withdraw-type switch cabinet fixed contact cover door opening device of self-locking after a kind of rational in infrastructure, reliable in action, the unlatching is provided.
Withdraw-type switch cabinet fixed contact cover door opening device of the present utility model includes the circuit breaker dolly that is promoted by propulsive mechanism and is fixed on three-phase upper static contact cover and following stationary contact head-shield in the switch cabinet; In the vehicle frame both sides of circuit breaker dolly a horizontal push pedal is installed respectively, a pair of driven wheel that cooperatively interacts respectively is installed in the switch cabinet body both sides simultaneously and drives tooth bar; A roller bearing that cooperates with above-mentioned horizontal push pedal is installed on the outer circumferential position of described driven wheel, roller bearing can be lifted when horizontal push pedal moves forward, driven wheel is rotated counterclockwise; Described driving tooth bar is a horizontal level, its front end is connected by the drive link of transmission mechanism with a vertical position, drive link is moved up and down, the upper/lower terminal of drive link cooperates transmission by rack and-pinion mechanism with last rotary arm shaft and backspin arm axle respectively, be separately installed with spiral arm and lower rotatory arm on the upper and lower rotary arm shaft, the front end of upper and lower spiral arm is hinged with last curtain door and lower shutter respectively, the front end of upper and lower curtain door is then spacing respectively on vertical direction in slide rail and the glidepath, and the front end of promptly upper and lower curtain door can move up and down along upper and lower slide rail respectively.
The utility model is rational in infrastructure, owing to carry out transmission by gear-tooth bar, makes that transmission efficiency height, light driving, the action of whole device are accurately reliable, and can realize self-locking on curtain door enable possition.
Description of drawings
Fig. 1 is the structural representation of the utility model when the curtain door is closed;
Fig. 2 is the structural representation of the utility model when the curtain door is opened.
Embodiment
As shown in the figure, include the circuit breaker dolly 1 that promotes by propulsive mechanism 19 in should withdraw-type switch cabinet fixed contact cover door opening device and be installed in three-phase upper static contact cover 2 in the cabinet and three-phase under stationary contact head-shield 3, circuit breaker dolly both sides are equipped with horizontal push pedal 4, be provided with the driven wheel 5 that cooperatively interacts simultaneously in the switch cabinet body both sides and drive tooth bar 6, the excircle of driven wheel is provided with roller bearing 7.When the circuit breaker dolly was pushed ahead, horizontal push pedal can touch roller bearing, and roller bearing is raised up to the upper surface of horizontal push pedal, and driven wheel 5 is rotated, and drive driving tooth bar 6 is done moving of fore-and-aft direction.The front end that drives tooth bar 6 drives drive link 9 upper and lower the moving of vertical position by transmission mechanism 8, described transmission mechanism 8 comprises some grades of travelling gears 10, and the tooth bar of the driving tooth bar 6 of travelling gear and horizontal direction and drive link 8 lower end vertical directions meshes respectively to transmit motion.Drive link 8 upper/lower terminals drive by rack and-pinion mechanism respectively and go up rotary arm shaft 11 and 12 rotations of backspin arm axle, and then spiral arm 13 and the last curtain door 15 of lower rotatory arm 14 drives and lower shutter 16 are overturn towards upper and lower both direction respectively synchronously along last slide rail 17 and glidepath 18, realize the unlatching of upper and lower curtain door.
Claims (2)
