Using the simple principle of leverage and the simple parts, the interlocking device solves the problems that can only be solved by electromagnetic locks. The interlocking device, simple in structure and easy for installation, can effectively prevent misoperation of an isolation switchgear during cabinet door opening.
Description
Technical field
The utility model relates to a kind of with motor-operating mechanism interlock in the cabinet of auto-lock function; this product is applicable to electric railway 27.5kV traction substation, switching station and section post isolating switch cabinet; this interlocking device is used for protective separation switch cubicle in the situation that opening cabinet door; can not manual operation, avoid because personnel neglect the misoperation causing.
Background technology
The isolating switch cabinet of at present domestic production, adopt electromagnetic lock to solve to close the door can manual operation more, opening the door can not manually operated scheme.This scheme is used for many years in isolating switch cabinet field, and technology maturation is stable, obtains users' accreditation.Shortcoming is complex structure, and electromagnetic lock need to be installed in isolating switch cabinet, makes isolating switch cabinet more complicated, and meanwhile, the existence of electromagnetic lock, has also increased a fault point, and the isolating switch cabinet fault causing due to the fault of electromagnetic lock happens occasionally.
Along with Large scale construction and the railway system continuous development of the reform of China's electric railway, miniaturization to isolating switch cabinet, intellectuality, high safety reliability, low maintenance workload etc. have proposed requirements at the higher level.Therefore the demand of the isolating switch cabinet to high-performance, high-quality, low price is more and more stronger, substitutes conventional art maturation but the isolating switch cabinet of complex structure, heaviness.Under this background, be eager to develop a kind of motor-operating mechanism interlock that is applicable to use in isolating switch cabinet cabinet.
Summary of the invention
For the deficiency existing on existing isolating switch cabinet, the purpose of this utility model is to provide a kind of with motor-operating mechanism interlock in the cabinet of auto-lock function, with meet isolating switch cabinet close cabinet door can manual operation, opening cabinet door cannot manually operated requirement.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of with motor-operating mechanism interlock in the cabinet of auto-lock function, this interlocking gear is arranged on the cabinet door with motor-operating mechanism front panel, this interlocking gear includes baffle plate, drive plate, cabinet door lock tongue, connecting bolt, angle bar is installed, on described cabinet door, be fixed with the cabinet door lock tongue rotating with cabinet door, baffle plate is rotatably mounted on motor-operating mechanism front panel by connecting bolt, Liang Ge stagger angle Tie Tong crosses connecting bolt and is fixed on motor-operating mechanism front panel, drive plate is rotatably mounted to two and installs between angle bar, two pawls on drive plate are through in the circular hole of two installation angle bar, the tail end of baffle plate inserts in the square hole of drive plate, the top of cabinet door lock tongue withstands on the inclined-plane of drive plate, in the time that cabinet door lock tongue moves, drive plate is flattened.
Effect of the present utility model is that this interlock adopts simple lever principle, utilizes the dead bolt on simple baffle plate, drive plate, isolating switch cabinet cabinet door, has solved the problem that originally needs electromagnetic lock to solve.Because dead bolt is arranged on isolating switch cabinet cabinet door, in the isolating switch cabinet cabinet door that closes, dead bolt has certain impulsive force to drive plate, and dead bolt is easy to insert in the square hole of motor-operating mechanism front panel, press drive plate and drive baffle plate motion, reach the object that baffle plate is started.The electromagnetic lock of former use, 500 yuan/platform, use this utility model locking device, 50 yuan/platform, merely with regard to this structure, every cost-saving 90%.Because this utility model locking device is simple in structure, substantially do not take the space of isolating switch cabinet, so, using the isolating switch cabinet of this utility model locking device, volume also reduces 5% accordingly.

Embodiment
Be illustrated with motor-operating mechanism interlock in the cabinet of auto-lock function of the present utility model by reference to the accompanying drawings.
Interlock with motor-operating mechanism in the cabinet of auto-lock function of the present utility model, be arranged on the cabinet door with motor-operating mechanism front panel, cabinet door is opened, and baffle plate blocks manual operation hole, avoid, in the situation that opening cabinet door, isolating switch cabinet being carried out to misoperation; Cabinet door closes, and baffle plate is opened, and can carry out manual operation to isolating switch cabinet.Should be with the interlock of motor-operating mechanism in the cabinet of auto-lock function, can not manual operation motor-operating mechanism when reaching isolating switch cabinet cabinet door and opening, function that can manual operation motor-operating mechanism when isolating switch cabinet door is closed.
Of the present utility model with motor-operating mechanism interlock in the cabinet of auto-lock function, this interlocking gear is arranged on the cabinet door with motor-operating mechanism front panel, this interlocking gear includes baffle plate 1, drive plate 2, cabinet door lock tongue 3, connecting bolt 4, angle bar 5 is installed, on described cabinet door, be fixed with the cabinet door lock tongue 3 rotating with cabinet door, baffle plate 1 is rotatably mounted on motor-operating mechanism front panel 6 by connecting bolt 4, two angle bar 5 being installed is fixed on motor-operating mechanism front panel 6 by connecting bolt 4, drive plate 2 is rotatably mounted to two and installs between angle bar 5, two pawls on drive plate 2 are through in the circular hole of two installation angle bar 5, the tail end of baffle plate 1 inserts in the square hole of drive plate 2, the top of cabinet door lock tongue 3 withstands on the inclined-plane of drive plate 2, in the time that cabinet door lock tongue 3 moves, drive plate 2 is flattened.
Of the present utility model with in motor-operating mechanism interlock use in the cabinet of auto-lock function, in the time that isolating switch cabinet cabinet door is opened, be installed on the dead bolt on isolating switch cabinet cabinet door, in the square hole from motor-operating mechanism front panel, exit, as shown in Figure 3, remove the restriction to drive plate 2, baffle plate 1, under the effect of gravity, overcomes the restriction of drive plate 2, freely falls, circular hole on motor-operating mechanism front panel 6 is blocked, formed self-locking.
