Abstract
The utility model belongs to the field of power supplying and dispatching equipment, more particularly relates to a valve combined mechanism of a switch cabinet, which comprises a stander. A lower valve guiding rod and a lower valve which can slide on the lower valve guiding rod are vertically arranged on the stander; two sides of the lower valve are provided with valve driving mechanisms, and each valve driving mechanism comprises a driving crankarm; the short-arm end part of the driving crankarm is hinged on the stander, and the long-arm end part is hinged at the outside of the lower valve through a lower-valve pull rod; the inside of the crank part of the driving crankarm is provided with a convex pin which can be touched by a movable handcart when advancing along a guide way, and the upper side of the lower valve is correspondingly provided with an unscrew type upper valve; the middle parts of two sides of the unscrew type upper valve are respectively hinged on the stander through a rotating shaft of the upper valve, and the end parts at the rear sides of the unscrew type upper valve are respectively hinged at the middle part of the long arm of the driving crankarm through a longitudinal connecting rod. When the movable handcart falls back to an examination position from a working position, the convex pin is released from restriction, and the upper valve, the lower valve and the valve driving mechanism make replacement under the action of the deadweight of the upper valve and a torsional spring. The valve combined mechanism not only facilitates the safe operation of the switch cabinet, but also has compact structure, reasonable design and good using effect.
Description
Technical field
The utility model relates to the power supplying and distributing equipment field, particularly a kind of switch cubicle valve combined mechanism.
Background technology
Handcart-type high pressure voltage switchgear is the power supplying and distributing equipment of being used widely at present.But main primary equipment has the withdraw-type handcart in the switch cubicle, as: vacuum circuit-breaker, PT car, the lightning-arrest car of PT, fusible core car, scale car, load close all kinds of combination vehicles and current transformers such as driving, ground connection car, current transformer generally is fixedly arranged in the cabinet, but the withdraw-type handcart then is installed on the guide rail, but the fixed contact that the withdraw-type handcart is corresponding with cabinet is pegged graft, and realizes that circuit connects.Because but the withdraw-type handcart will draw back sometimes, even need pull out outside the cabinet sometimes, therefore the protection valve is housed before charged fixed contact, and but this valve must realize mechanical interlocking with the withdraw-type handcart, but is strictly on guard against that operating personnel's accident entered charged interval or contact electrification position when the withdraw-type handcart was pulled out.But the valve up and down of the valve combined mechanism of existing high-tension switch cabinet all is a straight line switch mode up and down, and the space is big in the cabinet that takies.
Summary of the invention
The purpose of this utility model provides a kind of switch cubicle valve combined mechanism, and this mechanism not only helps the safety operation of switch cubicle, and compact conformation, and is reasonable in design, and result of use is good.
The technical solution adopted in the utility model is: this switch cubicle valve combined mechanism, comprise frame, it is characterized in that: the perpendicular valve guide rod and can be of being provided with down on the described frame at the following valve that descends slippage on the valve guide rod, described valve two sides down are provided with the valve driving mechanism, described valve driving mechanism comprises that one drives connecting lever, the galianconism end of described driving connecting lever is articulated on the frame, long-armed end is outside the valve pull bar is articulated in down valve down, but the inboard that described driving connecting lever turns portion is provided with the protruding pin that can be touched when guide rail is walked forward by the withdraw-type handcart, described valve upside correspondence down is provided with valve on the unscrewing type, the middle part of valve two sides is articulated on the frame through last valve rotating shaft respectively on the described unscrewing type, and rear end is articulated in through a longitudinal rod respectively and drives the long-armed middle part of connecting lever.
Distinguishing feature of the present utility model is that the valve driving mechanism adopts single connecting lever control valve up and down, and the crutches arm of comparing traditional on the market mid-cabinet of KYN is scissor, and structure is simpler, and is easier for installation, and cost is more cheap.In addition, last valve adopts and rotarily opens mode, compares the mode of vertical unlocking up and down of the mid-valve cashier's office in a shop of traditional KYN and has saved the space.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Embodiment
Switch cubicle valve combined mechanism of the present utility model, comprise frame 1, the perpendicular valve guide rod 2 and can be of being provided with down on the described frame 1 at the following valve 3 that descends slippage on the valve guide rod 2, described 3 liang of sides of valve down are provided with valve driving mechanism 4, described valve driving mechanism 4 comprises that one drives connecting lever 5, the galianconism end 6 of described driving connecting lever 5 is articulated on the frame 1, long-armed 7 ends warp valve pull bar 8 down is articulated in down valve 3 outsides, but the inboard that described driving connecting lever 5 turns portion is provided with the protruding pin 9 that can be touched when guide rail is walked forward by the withdraw-type handcart, described valve 3 upside correspondences down are provided with valve 10 on the unscrewing type, the middle part of 10 liang of sides of valve is articulated on the frame 1 through last valve rotating shaft 11 respectively on the described unscrewing type, and rear end is articulated in the middle part that drives connecting lever 5 long-armed 7 through a longitudinal rod 12 respectively.
Above-mentioned frame 1 is provided with and acts on the torsion spring 14 that drives connecting lever 5, drives connecting lever 5 and resets to make when protruding pin 9 constraint reliefs.
In the present embodiment, the described distance that goes up valve rotating shaft 11 valve front end master door body 13 to the unscrewing type is bigger than last valve rotating shaft 11 distance of valve rear end pin joint 15 to the unscrewing type, but when the withdraw-type handcart when the service position falls back on test position, protruding pin 9 constraint reliefs, upper and lower valve and valve driving mechanism reset under the effect of last valve front end master door body 13 deadweights and torsion spring 14.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection range of the present utility model.
