Description
Technical field
the utility model belongs to high pressure equipment for power transmission and distribution, relates to the middle-placed switch cabinet valve locking mechanism in a kind of handcart switch cabinet.
Background technology
Handcart switch cabinet is a kind of switch cubicle conventional in high pressure equipment for power transmission and distribution; It generally includes the cabinet that fixed contact is installed and the circuit breaker cart that moving contact is installed, and circuit breaker cart can push or pull out cabinet.When circuit breaker cart pushes, the valve that is blocked in fixed contact the place ahead in cabinet need to be opened, and makes the moving contact on circuit breaker cart peg graft and coordinate with the fixed contact in being arranged on cabinet; When circuit breaker cart is pulled out, the valve in cabinet need to be closed again.The valve operated by rotary motion of switch cubicle has valve locking mechanism, and when guaranteeing that circuit breaker cart is pulled out, valve, in reliable closed condition, tries to avert accidents.
Described valve locking mechanism comprises valve connecting lever, valve connecting lever lockplate and junction panel, and one end of described valve connecting lever is arranged on switch cubicle by jointed shaft, and the other end is connected with the parts of mechanism for opening switch cabinet valve.When valve connecting lever can rotate counterclockwise around jointed shaft, when the other end of described valve connecting lever can rotate counterclockwise downwards, for the mechanism of opening switch cabinet valve, could move, and then open the valve of switch cubicle.When valve connecting lever can not rotate counterclockwise around jointed shaft, when the other end of described valve connecting lever can not rotate counterclockwise downwards, locked for the mechanism of opening switch cabinet valve, the valve of switch cubicle can not be opened.
When circuit breaker cart is during away from the valve of switch cubicle, junction panel rotates counterclockwise under the effect of resetting means, drive valve connecting lever lockplate to lock valve connecting lever, valve connecting lever can not rotate counterclockwise around jointed shaft, and the valve of switch cubicle is in the lock state.When circuit breaker cart near and during the valve of clamping switch cabinet, junction panel clockwise rotates, and drives valve connecting lever lockplate to carry out release to valve connecting lever, and valve connecting lever can rotate counterclockwise around jointed shaft, the valve of switch cubicle is in released state, and the valve of switch cubicle can be opened.
But the complex structure of the valve locking mechanism of existing handcart switch cabinet, reliability of operation is poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the middle-placed switch cabinet valve locking mechanism that reliability is high.
Middle-placed switch cabinet valve locking mechanism of the present utility model, comprises valve connecting lever, valve connecting lever lockplate and junction panel; One end of described valve connecting lever is arranged on switch cubicle by jointed shaft, and the other end is connected with the parts of mechanism for opening switch cabinet valve; Described junction panel can drive valve connecting lever lockplate to carry out release to valve connecting lever when circuit breaker cart compresses, and can, at circuit breaker cart away from rear, drive valve connecting lever lockplate to lock valve connecting lever under the effect of resetting means; The tail end that described valve connecting lever is hinged on that end on switch cubicle is provided with the projection of a level; The motion of described junction panel can drive valve connecting lever lockplate to push down and away from projection, and then valve connecting lever is carried out to the locking and unlocking.
It also comprises the fixed head that is positioned at valve connecting lever lockplate top being fixedly mounted on switch cubicle, is provided with one section of chute on described fixed head; Described junction panel is arranged on fixed head by jointed shaft; On described junction panel, be also provided with mounting hole, in described mounting hole, be provided with through cunning, and be fixedly mounted on the bearing pin on valve connecting lever lockplate; Described resetting means is back-moving spring, and described junction panel is connected with fixed head by back-moving spring.
The utility model has the advantage of: the utility model functional reliability is high, simple in structure.

Embodiment
below in conjunction with the drawings and specific embodiments, middle-placed switch cabinet valve locking mechanism of the present utility model is described further.
a middle-placed switch cabinet valve locking mechanism, comprises valve connecting lever 01, valve connecting lever lockplate 02 and junction panel 03; One end of described valve connecting lever 01 is arranged on switch cubicle by jointed shaft, and the other end is connected with the parts of mechanism for opening switch cabinet valve; Described junction panel 03 can drive 02 pair of valve connecting lever of valve connecting lever lockplate 01 to carry out release when circuit breaker cart compresses, and can, at circuit breaker cart away from rear, under the effect of resetting means, drive 02 pair of valve connecting lever 01 of valve connecting lever lockplate to lock; The tail end that described valve connecting lever 01 is hinged on that end on switch cubicle is provided with the projection 011 of a level; The motion of described junction panel 03 can drive valve connecting lever lockplate 02 to push down and away from projection 011, and then valve connecting lever 01 is carried out to the locking and unlocking.
It also comprises the fixed head 04 that is positioned at valve connecting lever lockplate 02 top being fixedly mounted on switch cubicle, is provided with one section of chute 06 on described fixed head 04; Described junction panel 03 is arranged on fixed head 04 by jointed shaft; On described junction panel 03, be also provided with mounting hole 031, in described mounting hole 031, be provided with through chute 06, and be fixedly mounted on the bearing pin 07 on valve connecting lever lockplate 02; Described resetting means is back-moving spring 05, and described junction panel 03 is connected with fixed head 04 by back-moving spring 05.
