Abstract
The utility model relates to a driving crankarm of a flexible door mechanism of a high-voltage switch cabinet, which comprises a triangular main body, wherein roller wheels are arranged on the main body, the roller wheels are triggered when a withdrawable handcart moves along the direction of a guide rail, and the upper edge of the triangular main body are connected with a long arm. In the utility model, on the one hand, the cylindrical surfaces of the roller wheels of the crankarm in the original technology for driving, on the other hand, the handcart is additionally arranged to drive the long arm, and through adopting the double matched driving mode, the operation has high reliability, and the effect is better.
Description
Technical field
The utility model relates to high pressure power transmission and distribution switchgear, is specifically related to a kind of accessory of high-tension switch cabinet valve mechanism.
Background technology
Moveable high-voltage switchgear is widely used in the Allocation transformer in industries such as power plant, transformer station, industrial and mining enterprises, railway transportation, skyscraper or field, its structure generally includes cabinet and circuit breaker cart, circuit breaker cart can push or pull out cabinet by road wheel, with convenient maintenance and maintenance.The Chinese utility model patent ZL200920191603.9 of the applicant's invention, a kind of switch cubicle valve combined mechanism is provided, this mechanism not only helps the safety operation of switch cubicle, has characteristics such as compact conformation, manufacturing is easy for installation, operational reliability is high, cost is low.This mechanism in use also finds certain problem, and the driving connecting lever is a triangular structure, is provided with the roller that the withdraw-type handcart touches but drive connecting lever when guide rail is walked forward.The driving connecting lever of this mechanism only cooperates with the handcart plane with the roller face of cylinder on the triangle, and mating surface is few, and valve is opened and occurred malfunctioning phenomenon sometimes, in addition, the versatility of this driving connecting lever is poor, to some handcart incompatibilities, needs the drive part of circuit breaker cart is made again.
The utility model content
The purpose of this utility model provides a kind of driving connecting lever of high-tension switch cabinet valve mechanism, and this drives connecting lever and adopts two modes that cooperate, and it is more reliable that valve is opened, and it is rational in infrastructure, and result of use is good.
The technical scheme that technical problem adopted that the utility model solves is: a kind of driving connecting lever of high-tension switch cabinet valve mechanism, comprise triangular shaped body, but main body is provided with the roller that the withdraw-type handcart touches when guide rail is walked forward, it is characterized in that being connected with long-armed in the top of triangular shaped body.
During use, activity cylindrical sleeve on the circuit breaker cart contacts with the face of cylinder of connecting lever upper roller, because the activity cylindrical sleeve on the handcart is higher than the face of cylinder of connecting lever upper roller, activity cylindrical sleeve on the handcart is pressed on the roller face of cylinder on the big connecting lever, the promotion connecting lever clockwise rotates, when handcart continues to shake into, activity cylindrical sleeve on the handcart breaks away from the face of cylinder of connecting lever upper roller, change the face of cylinder of being pushed down the roller on the connecting lever by the cooperation of the pressing plate on handcart plane into, the activity cylindrical sleeve on the handcart is pushed down the long-armed cooperation plane on the connecting lever simultaneously.
The beneficial effects of the utility model are: the utility model adopts the face of cylinder on the connecting lever upper roller of original technology to drive on the one hand, has increased handcart in addition and has driven long-armed, adopts two modes that cooperate, operational reliability height, better effects if.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the principle schematic of the utility model embodiment;
Fig. 3 is the mounting structure schematic diagram of the utility model embodiment.
Among the figure: 1, main body 2, roller 3, long-armed 4, handcart 5, activity cylindrical sleeve 6, pressing plate 7, cabinet
Embodiment
According to Fig. 1, Fig. 2 and shown in Figure 3, embodiment states to the utility model below:
Among Fig. 1, a kind of driving connecting lever of high-tension switch cabinet valve mechanism comprises triangular shaped body 1, but main body 1 is provided with the roller 2 that the withdraw-type handcart touches when guide rail is walked forward, and the top of triangular shaped body 1 is connected with long-armed 3.
As Fig. 2 and Fig. 3, during use, when handcart 4 shakes into cabinet 7, activity cylindrical sleeve 5 on the circuit breaker cart 4 contacts with the face of cylinder of connecting lever upper roller 2, because the activity cylindrical sleeve 5 on the handcart 4 is higher than the face of cylinder of connecting lever upper roller 2, activity cylindrical sleeve 5 on the handcart 4 is pressed on roller 2 faces of cylinder on the connecting lever, the promotion connecting lever clockwise rotates, when handcart 4 continues to shake into, activity cylindrical sleeve 5 on the handcart 4 breaks away from the face of cylinder of connecting lever upper roller 2, change the face of cylinder of being pushed down the roller 2 on the connecting lever by the 5 cooperation planes of the pressing plate on the handcart 4 into, the activity cylindrical sleeve 5 on the handcart 4 is pushed down the long-armed 3 cooperation planes on the connecting lever simultaneously.
When handcart 4 shakes out cabinet 7, at first the pressing plate 5 of the face of cylinder of connecting lever upper roller 2 on handcart 4 cooperates plane rolling, on the connecting lever long-armed 3 cooperates the activity cylindrical sleeve of plane on handcart 4 to move for 5 times simultaneously, when handcart 4 continues to shake out, the pressing plate 5 that the face of cylinder of connecting lever upper roller 2 breaks away from the handcart 4 cooperates the plane, on the connecting lever long-armed 3 cooperates the activity cylindrical sleeve 5 on the plane disengaging handcart 4 simultaneously, withstand on the handcart 4 the activity cylindrical sleeve 5 times by 2 faces of cylinder of the roller on the connecting lever, connecting lever is rotated counterclockwise.
The general structure of the valve of the utility model embodiment is just improved driving connecting lever with Chinese utility model patent ZL200920191603.9, and the upper and lower valve opening and closing principle of valve combined mechanism is not described herein at this.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from disclosed content of the present utility model all should be thought protection range of the present utility model.
