Abstract
The utility model provides a guide rail device of electrified railway armored withdrawable metal-enclosed switch equipment, which comprises a pull bar. One end of the pull bar is arranged on a welding shaft on the outer side of a guide rail. A connecting lever is arranged on one welding shaft of the guide rail. A second connecting rod is arranged on the other welding shaft of the guide rail. One end of the second connecting rod is hinged to the connecting lever while the other end is hinged to a first connecting rod. A four-connecting-rod mechanism is formed. The pull bar on the outer side of the guide rail is arranged in a way to be coaxial to the second connecting rod. One end of a third connecting rod is arranged on the pull bar. One side of a baffle plate is arranged on the guide rail while the other side is connected with the third connecting rod. The guide rail device of the switch equipment can guide and mechanically limit the entry and the withdrawal of a breaker by cooperating with a valve mechanism and a floor type breaker. The guide rail device can further have mechanical linkage effects on an aviation socket of the breaker and prevent the aviation socket from being mistakenly operated when the breaker is working. The guide rail device plays a positive role in improving safety performances of equipments and preventing mistaken operations.
Description
Technical field
The utility model relates to a kind of track-type facilities, is the track-type facilities that a kind of Novel electric electrified railway is used armoured specifically.
Background technology
The electric railway metal enclosed switchgear now mostly is case structure, and circuit breaker does not have track-type facilities and valve mechanism when advancing, and the stopping means of circuit breaker is only also a spring assembly, and the security performance of switchgear is unreliable.
Summary of the invention
For improving above-mentioned situation, the utility model provides the track-type facilities of a kind of electric railway with armoured, this utility model motion is reliable, transmission performance is high, spacing accurately and mechanical chain reliable.
For achieving the above object, the technical solution adopted in the utility model is to provide the track-type facilities that a kind of electric railway is used armoured, this device is arranged on the bottom of breaker chamber, and wherein: this device includes pull bar, the 1st connecting rod, the 2nd connecting rod, the 3rd connecting rod, guide rail, limiting plate, connecting lever, baffle plate;
One end of described pull bar is arranged on the welding axle in the guide rail outside, connecting lever is arranged on a root bead spindle of guide rail, and the 2nd connecting rod is arranged on another root bead spindle of guide rail, an end of the 2nd connecting rod and connecting lever pin joint, the other end and the 1st connecting rod pin joint form a quadric chain; The pull bar and the 2nd coaxial installation of connecting rod in the guide rail outside, the 3rd connecting rod one end is arranged on pull bar, and a side of baffle plate is arranged on guide rail, and opposite side is connected with the 3rd connecting rod.
The beneficial effects of the utility model are track-type facilitiess that this electric railway is used armoured, coordinate valve mechanism and console mode circuit breaker to use, can be to circuit breaker push and withdraw from guide effect and the mechanical position limitation effect played, also can play to the aviation socket of circuit breaker the mechanical chain effect simultaneously, make aviation socket when circuit breaker is worked not by misoperation.To the security performance that improves equipment with prevent that the misoperation aspect all has positive effect.

Embodiment
By reference to the accompanying drawings the track-type facilities of electric railway of the present utility model with armoured is illustrated.
As shown in Figure 1, the electric railway of the present utility model track-type facilities of armoured, this device is arranged on the bottom of breaker chamber, and this device includes pull bar 1, the 1st connecting rod 2, the 2nd connecting rod 3, the 3rd connecting rod 6, guide rail 7, limiting plate 4, connecting lever 5, baffle plate 8.
Pull bar one end is arranged on the welding axle in the guide rail outside, the connecting rod pin joint of the valve mechanism of the other end and this device.Connecting lever 5 is arranged on a root bead spindle of guide rail 7, and the 2nd connecting rod 3 is arranged on another root bead spindle of guide rail 7, an end of the 2nd connecting rod 3 and connecting lever 5 pin joints, and the other end and the 1st connecting rod 2 pin joints form a quadric chain; The pull bar 1 in guide rail 7 outsides is arranged on pull bar with the 2nd coaxial installation of connecting rod 3, the 3rd connecting rod 6 one ends, and a side of baffle plate 8 is arranged on guide rail 7, and opposite side is connected with the 3rd connecting rod 6.
The height of described guide rail 7 is between 120 ~ 300mm.
Electric railway of the present utility model is achieved in that with the track-type facilities function of armoured
When circuit breaker push-on switch cabinet, the push pedal on circuit breaker pushes in the opening of connecting lever; Along with the circuit breaker reach, drive the 1st connecting rod and the rotation of the 2nd connecting rod in quadric chain, the 1st connecting rod drives coaxial mounted pull bar motion subsequently, produces the range difference on a height, thereby makes the valve mechanism that is attached thereto open or close.Simultaneously, in pull bar when motion, drive the movement tendency that the 3rd connecting rod produces a horizontal direction, make with one of the coaxial baffle plate that is connected of end be rotated, thereby the aviation socket of circuit breaker is carried out mechanical chain.And when circuit breaker moved to the service position, limiting plate carried out mechanical position limitation to connecting lever.This device can guarantee the accurate and reliable of circuit breaker position more reliably, and the personnel that prevent carry out misoperation to aviation socket when circuit breaker is worked.
