Abstract
The utility model relates to a metal shutter with an armored removable switchgear of anti-jam and antistatic functions. The metal cabinet of this utility model is provided with an innovative needle bearing-cross sprocket drive, two hinge foldable full-closed metal shutters of an upper and lower valve dead weight counteracting force couple design, and a shutter left and right trajectory guide rail. The closing and opening operation of the shutter of this switch equipment is flexible, to the point and reliable; when the shutter is closed, the whole epoxy contact box is tightly sealed, which forms an effective isolation, ensures that the operator and maintenance staff do not contact charged bodies and the epoxy contact box, has a good antistatic safety property, and ensures the safety and reliability of the operation.
Description
Technical field
The utility model relate to a kind ofly have the needle bearing-chain gear transmission of intention, the armored withdraw type switch cubicle of couple design, totally-enclosed collapsible antistatic metal dampers is supported in valve deadweight mutually up and down.
Background technology
At present, there is following deficiency in the known middle armored withdraw type switch cubicle of grade of pressing:
● valve structure adopts single piece of sheet metal, when handcart is pulled away from cabinet (be in and remove the position), single piece of sheet metal can not be in fixed contact the complete packing of major loop epoxy body insulating contact box of electriferous state, then exists the people to touch the harm that contact box is subjected to the electrostatic charge of gathering on it;
● valve open and close to adopt the round steel spindle guide to drive mechanism, and it is puckery to be subject to blocked portion.
Summary of the invention
For remedying existing middle armored withdraw type switch cubicle above shortcomings of pressing grade, the utility model provides a kind of armored withdraw type switch cubicle that adopts collapsible valve, this switchgear human body when valve is closed touches fully less than epoxy body insulating contact box, and the open and close operation of valve is light and handy flexibly reliable.
● metal dampers needle bearing-chain gear transmission, form by last valve, following valve, metal dampers is two collapsible and mutual couple design, totally-enclosed antistatics of supporting of deadweight up and down.
● the valve positioning rotating shaft has sprocket wheel, and last lower sprocket connects by the chain that intersects.
● the valve both sides are equipped with needle bearing respectively, and bearing is inserted in the track groove of engagement valve left and right rail.
Description of drawings
Fig. 1 is valve and drive mechanism (dorsal view), among the figure 1, positioning rotating shaft 3, the chain 4 of valve left side track guide rail 2, band chain wheel, go up padlock hole 8 on valve 5, the right track guide rail 6 of valve, needle bearing 7, the valve, valve 9, kinematic link down.
Embodiment
The execution mode that the utility model addresses the above problem employing is:
Valve is needle bearing-chain gear transmission, couple design, two collapsible totally-enclosed antistatic metal dampers are supported in the valve deadweight mutually up and down:
● valve is two folding metal sheets compositions of hinge up and down, with the propelling of handcart with pull out the opening and closing of interlock valve, be designed to all positions except that work, the equal integral body of epoxy body contact box is tightly sealed by valve, and effectively isolation of formation (single break 〉=320mm); When maintenance waits and to need, up and down valve can open and close respectively, the valve of the charged side of lockable (adding padlock in addition).
Beneficial effect is, guarantees that operator and repair and maintenance personnel can not touch electrified body and epoxy body contact box, and safe static electricity resistance is good;
● upper and lower collapsible valve stiff end penetrates the positioning rotating shaft that a left side (accompanying drawing 1 discipline 2) has sprocket wheel respectively, last lower sprocket connects by the chain (GB1243-97 chain 06B-X143) that intersects, upper and lower collapsible valve movable end both sides are equipped with needle bearing (KVZ needle bearing 25 * 12 * 14) respectively, and bearing inserts in the track groove that is engaged in the left and right track guide rail of cabinet both sides valve fully.Forward and back with handcart, the interlock kinematic link of valve movable end both sides down moves up and down, following valve pushes away, leaves behind kinematic link, do skid motion up and down in the left and right track guide-track groove of each comfortable valve of the needle bearing of both sides, drive valve and press projected path do expansion and folding, last valve is then done counter motion by the chain that intersects with following valve synchronously, finishes the open and close function of valve jointly.
Beneficial effect is that the coefficient of friction of needle bearing rolling-sliding type motion is significantly smaller than the coefficient of friction of the pure slip of dead steel axle, can prevent operating bite; Valve intersects the couple design that sprocket wheel chain drive deadweight is supported mutually up and down, guarantee the valve on-off action put in place flexibly, light and handy reliable.
Claims (3)
1. armored withdraw type switch cubicle that adopts collapsible metal dampers, in cabinet, be provided with the metal dampers of screening every main switch insulating contact box, it is characterized in that: metal dampers is by last valve, down valve is formed, up and down metal dampers be two collapsible and conduct oneself with dignity and support mutually.
2. the armored withdraw type switch cubicle of the collapsible metal dampers of employing according to claim 1 is characterized in that: the valve positioning rotating shaft has sprocket wheel, and last lower sprocket connects by the chain that intersects.
3. the armored withdraw type switch cubicle of the collapsible valve of employing according to claim 1 is characterized in that: the valve both sides are equipped with needle bearing respectively, and bearing is inserted in the track groove of engagement valve left and right rail.
