By being fixed on the loose-leaf I socket cross bar I above them, valve plate III and valve plate IV are respectively by being fixed on the loose-leaf I socket cross bar II above them simultaneously respectively for valve plate I and valve plate II.
Valve plate II is by being fixed on the loose-leaf II socket screw rod I above it, and valve plate III is by being fixed on the loose-leaf II socket screw rod II above it simultaneously.
In the time of in handcart enters switch cubicle, handcart valve pivot pin by handcart from the weight big connecting rod, the valve chute moves downward under small rod drive valve plate II edge by drawing to make it, and then valve plate II drive valve plate I rotates around following curtain shaft, valve is opened, steel wire rope draws valve plate III to move upward along last valve chute simultaneously, and then door-plate III drive valve plate IV opens valve around the upwards rotation of last curtain shaft.When handcart withdrawed from, valve plate I, valve plate II, valve plate III and valve plate IV all realized counter motion, thereby closed valve automatically.Therefore along with the entering or withdrawing from of handcart, valve is realized opening or closing automatically by valve mechanism.
The beneficial effect that the utility model had is:
1, valve adopts the connecting rod transmission up and down, and integral rigidity is strong, definitely can guarantee the interlock of valve up and down.
2, valve mechanism is fixed on the sidewall of left and right sides cabinet, and its fixed-area is also bigger, makes the connecting rod left-right deviation of valve less, cabinet car quality of fit height.
3, its rotation place adopts cover to pivot; And the place that moves up and down adopts the mode of rotating of overlapping, and about moving along trough roller, its frictional force is less, and valve is up and down easily laborsaving, resets certainly.
4, adopt the ironwork door, not only that primary conductive is partially enclosed, and contact good and ground connection with cabinet, with ground be same current potential, thereby assurance maintainer's safety.
It is attractive in appearance to the utlity model has monnolithic case, and complete property is strong, be convenient to install, and the structural strength height, characteristics such as adaptability is strong have satisfied switch cubicle " five is anti-" functional requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 for the utility model when the structural representation of handcart during in test position;
Fig. 3 for the utility model when the structural representation of handcart during in the service position.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, coulisse I17 and coulisse II12 are separately fixed on switch cabinet body left side wall 21 and the cabinet right side wall 22, pulley I and pulley II15 are separately fixed at the tip position of coulisse I17 and coulisse II12, steady pin I8 and steady pin II1 are separately fixed at the bottom position of switch cabinet body left side wall 21 and cabinet right side wall 22, the bottom of big connecting rod I18 and big connecting rod II2 is socketed in respectively on steady pin I8 and the steady pin II1, valve plate I4, valve plate II7, valve plate III19 and valve plate IV13 are located between coulisse I17 and the coulisse II12 and arrange from bottom to top successively, wherein valve plate I4 and valve plate II7 form valve down, valve on valve plate III19 and the valve plate IV13 composition.Valve plate I4 and valve plate II7 are respectively by being fixed on the loose-leaf I5 socket cross bar I6 above them, valve plate III19 and valve plate IV13 are respectively by being fixed on the loose-leaf I5 socket cross bar II27 above them simultaneously, following curtain shaft 20 and last curtain shaft 14 are separately fixed at bottom and the top of coulisse I17 and coulisse II12, and valve plate I4 and valve plate IV13 are separately fixed at curtain shaft 20 and last curtain shaft 14 under the loose-leaf I5 socket above them.The position that is positioned at valve plate III19 on coulisse I17 and the coulisse II12 has the corresponding valve chute 23 of going up, the position that is positioned at valve plate II7 simultaneously on coulisse I17 and the coulisse II12 has corresponding valve chute 24 down, valve plate II7 is by being fixed on the loose-leaf II10 socket screw rod I25 on its top left right side wall, valve plate III19 is by being fixed on the loose-leaf II10 socket screw rod socket screw rod II9 on its bottom, left right side wall, valve chute 24 and last valve chute 23 under the outer end difference clamping of screw rod I25 and screw rod II9 simultaneously.The top of big connecting rod I18 and big connecting rod II2 is hinged small rod I26 and small rod II3 respectively, the top of small rod I26 and small rod II3 is connecting screw rod I25 respectively, be overlapped on the steel wire rope 16 on pulley I and the pulley II15 respectively, the one end is by steel wire rope connecting plate connecting screw rod I25, and the other end is by steel wire rope connecting plate connecting screw rod II9.
