Abstract
The invention belongs to high-voltage switch equipment, and relates to a valve driving device of a switch cabinet in a handcart type switch cabinet. The valve driving device comprises fixed plates arranged on two sides of a switch cabinet body, guide rails positioned on the inner sides of the fixed plates and capable of allowing a handcart to slide thereon, and a four-link mechanism capable of driving a valve to move; a return spring capable of returning the four-link mechanism to the closed position of the valve is arranged between the four-link mechanism and the fixed plates; and pin shafts C are fixed on two sides of a frame of the handcart, and the pin shafts move from back to front together with the handcart in the process of pushing the handcart to the cabinet body and can push the four-link mechanism to move to the opened position of the valve. By adopting the structure, the valve driving device is good in reliability, simple in structure, convenient to manufacture and install and low in cost, and meets the using requirements of the circuit breaker handcart for opening and closing of the valve.
Description
?
Technical field
The invention belongs to high voltage switchgear, relate to a kind of valve drive unit that is used for the switch cubicle of handcart switch cabinet.
Background technology
Handcart switch cabinet is a kind of switch cubicle commonly used in the controller switching equipment; It generally includes the moving contact that cooperatively interacts and the cabinet and the circuit breaker cart of fixed contact is installed, and circuit breaker cart can push or pull out cabinet.When circuit breaker cart when pushing, being blocked in the cabinet valve in fixed contact the place ahead need open, and the moving contact on the circuit breaker cart is cooperated with fixed contact grafting in being installed in cabinet; When circuit breaker cart was pulled out, the valve in the cabinet need be closed again, so that fixed contact is protected.The valve type of drive of existing handcart switch cabinet is varied, and its complex structure, manufacturing cost height and reliability of operation are poor; Can't guarantee the action message and the operation of sleeve mechanism.
Summary of the invention
The technical problem that the present invention will solve provides a kind of simple in structure, and cost is low, the valve drive unit of reliable switch cubicle.
In order to solve the problems of the technologies described above; The valve drive unit of switch cubicle of the present invention; Comprise fixed head that is arranged at the switch cabinet body both sides and the made handcart that is positioned at the fixed head inboard guide rail along its slip; Also comprise the quadric chain that can drive valve action, be provided with between said quadric chain and the fixed head and can make quadric chain return back to the back-moving spring of valve off-position; The vehicle frame both sides of said handcart are fixed with pivot pin C, handcart push in the cabinet process pivot pin whip car by after move forward and can promote quadric chain and move to the valve open position.
But said quadric chain comprises and being hinged on the cabinet base plate and the input connecting lever and the output toggle arm of swing, and is hinged on the connecting plate between input connecting lever and the output toggle arm through the bearing pin A of front end and the bearing pin B of rear end.
Also be provided with the limiting plate that can swing on the said fixed head, said limiting plate is provided with the groove that cooperatively interacts with bearing pin B and lock bearing pin B, is provided with between limiting plate and the fixed head to make groove be stuck in the locking spring on the bearing pin B; Can limiting plate be pushed away bearing pin B in the process that said pivot pin C moves forward.
Be provided with connecting rod between said quadric chain and the valve, the valve of switch cubicle is driven by connecting rod.
After adopting above-mentioned structure, the valve drive unit of switch cubicle of the present invention, the quadric chain that utilize to be provided with move the opening and closing that drive valve; Limiting plate and limiting plate through being provided with are provided with the groove that cooperatively interacts with bearing pin B, and it is spacing to carry out stop, have guaranteed the not closed reliability of time spent valve; Its good reliability; Simple in structure, make easy for installationly, cost is low, has satisfied the instructions for use of circuit breaker cart to the valve opening and closing.
Description of drawings
Fig. 1 pulls out the sketch map of state at handcart for the valve drive unit of switch cubicle of the present invention;
Fig. 2 advances the attitude sketch map of shape at handcart for the valve drive unit of switch cubicle of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the valve drive unit of switch cubicle of the present invention is done further explain.
As shown in the figure; The valve drive unit of switch cubicle of the present invention; Comprise the fixed head 1 that is positioned at the switch cabinet body two bottom sides and prolong the guide rail 2 of its slip at fixed head 1 inboard the made handcart that is provided with; Also comprise the quadric chain that can drive valve action, be provided with connecting rod 14 between quadric chain and the valve, valve is by its action of driving of connecting rod 14; But quadric chain comprises input connecting lever 5 and the output toggle arm 6 of reciprocally swinging and is hinged on the connecting plate 7 between input connecting lever 5 and the output toggle arm 6 through bearing pin A and bearing pin B.Between quadric chain and the fixed head 1 back-moving spring 12 is set; The vehicle frame both sides of handcart are fixed with the pivot pin C that can promote the quadric chain action.Also be provided with the limiting plate 4 of lockable quadric chain on the fixed head 1, limiting plate 4 is provided with the groove 8 that cooperatively interacts with bearing pin B, is provided with locking spring 13 between limiting plate 4 and the fixed head.
Its use is following:
When circuit breaker cart advanced, bearing pin C moved forward with handcart, at first pushes limiting plate 4 open; Quadric chain is unlocked; The process of advancing at pivot pin C promotes input connecting lever 6 and drives output toggle arm 6 and connecting rod 14, and then drives valve and open, and connecting plate 7 is depressed to level and slides along connecting plate 7 until lock pin C; Valve was opened and was put in place this moment, and quadric chain no longer moves
When circuit breaker cart withdrawed from, output toggle arm 6 turned clockwise under the effect of back-moving spring 12, and through winning 7 in succession; Pass motion to input connecting lever 5; When pin C broke away from input connecting lever 5 fully, limiting plate 4 clockwise rotated under the effect of reduction torsion spring 13, and the groove on it snaps in pivot pin B automatically; The locking quadric chain, thus realize closing and self-sustaining of valve.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art is made in essential scope of the present invention also should belong to protection scope of the present invention.
