Embodiment
Core of the present utility model is to provide a kind of movable door mechanism for high voltage switch cabinet, for solving the valve mechanism large problem that takes up room.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the structural scheme of mechanism of a kind of movable door mechanism for high voltage switch cabinet that Fig. 1 provides for the utility model specific embodiment scheme.
In a kind of specific embodiment, the utility model provides a kind of movable door mechanism for high voltage switch cabinet, concrete, this valve mechanism comprises car switch 4, guide rail 1, upper contact head baffle plate 6, lower contact baffle plate 13, also comprise the fixed pulley 3 that slides and be arranged at the movable pulley 2 in guide rail 1 and be fixedly installed on guide rail 1 outside, car switch 4 can reciprocatingly slide in guide rail 1.
Wherein, upper contact head baffle plate 6 is connected with movable pulley 2 by the first stay cord 8, and lower contact baffle plate 13 is connected with movable pulley 2 by the second stay cord 12.Concrete, the other end that movable pulley 2, the first stay cords 8 are fixed in one end of the first stay cord 8 is walked around fixed pulley 3 and is connected in upper contact head baffle plate 6; The other end that movable pulley 2, the second stay cords 12 are fixed in one end of the second stay cord 12 is walked around fixed pulley 3 and is connected in lower contact baffle plate 13.Movable pulley 2 drives the first stay cord 8 and upper contact head baffle plate 6 controlled by the second stay cord 12 and lower contact baffle plate 13 is opened, and this movable door mechanism for high voltage switch cabinet is also provided with for controlling the spring of upper contact head baffle plate 6 and lower contact baffle plate 13 closures.
Concrete, fixed pulley 3 is for changing the direction of the first stay cord 8 and the second stay cord 12 transmissions, certainly, also can adopt the structures such as polished rod or block to substitute fixed pulley 3, to realize the function that changes dragline-transmission direction, so arrange, movable pulley 2 just can pull stay cord while sliding to inside switch cabinet, thereby drives upper contact head baffle plate 6 and 13 motions of lower contact baffle plate.
It should be noted that, the quantity of the fixed pulley 3 in this programme is at least one, and a plurality of fixed pulleys 3 are preferably set in the present embodiment, to realize the conversion of the different directions of dragline-transmission.
It should be noted that, the spring in this programme comprises that the first spring 7 and 11, two springs of the second spring all can be fixed on the body of switch cubicle.The first 7 pairs, spring upper contact head baffle plate 6 applies a downward active force, the lower contact baffle plate 13 of the second 11 pairs, spring applies an active force making progress, the active force of the first spring 7 or the second spring 11 can be controlled baffle plate closure, and the thrust than car switch 4 is little, so arrange, when car switch 4 is pulled out switch cubicle, spring just can pull baffle plate to make position, and car switch 4 just can overcome the active force of spring and baffle plate is opened when pushing switch cubicle.
It should be noted that, the stay cord that the stay cord in this programme can be made for nylon rope, steel wire rope or other composite materials, it can guarantee enough tensile strength.Preferably, the first stay cord 8 in the present embodiment scheme and the second stay cord 12 are steel wire rope.
When by car switch 4 push-on switch cabinet, car switch 4 promotes movable pulley 2 and moves to inside switch cabinet, movable pulley 2 overcomes the elastic force of spring by the first stay cord 8 and the second stay cord 12, and driving upper contact head baffle plate 6 and lower contact baffle plate 13 to open, car switch moving contact 5 just can contact with lower fixed contact 10 with upper static contact 9 like this; When car switch 4 is pulled out to switch cubicle, the active force of 4 pairs of movable pulleys 2 of car switch disappears, and the elastic force of spring is controlled upper contact head baffle plate 6 and lower contact baffle plate 13 closures.
This programme is applied to the mode of pulley and stay cord combination transmission in movable door mechanism for high voltage switch cabinet, not only operating physical force is less, stable drive is reliable, and novelty simple in structure, take up room to narrow down to and be about 1/10th of jointed gear unit, visible, this programme has dwindled the space that valve mechanism takies greatly, has also reduced manufacturing cost.
The utility model also provides a kind of high-tension switch cabinet that comprises above-mentioned movable door mechanism for high voltage switch cabinet, the derivation of beneficial effect that this high-tension switch cabinet produces and the derivation of the beneficial effect that above-mentioned movable door mechanism for high voltage switch cabinet brings are substantially similar, therefore repeat no more herein.
