Abstract
The utility model discloses a chassis vehicle device with a door-closing operation function and an emergency opening function. The device comprises a chassis, a cross beam, a left locking plate, a handle welding plate, a lead screw, a right locking plate and a sliding roller, wherein the left locking plate and the right locking plate are respectively arranged at the left and right sides of the handle welding plate and lock the handle welding plate; and the sliding roller drives the left locking plate and the right locking plate to move, thus the handle welding plate moves backwards and a handle is inserted into the lead screw, so that a circuit breaker can shake inwards and outwards. The chassis vehicle device with the door-closing operation function and the emergency opening function is characterized in that an interlocking device with a built-in sliding rod is mounted on the chassis vehicle device and the sliding rod can hook an interlocking part on a cabinet door. The chassis vehicle device with the door-closing operation function and the emergency opening function has the beneficial effects that the structure is simple; the design is subtle; a door-closing device, the interlocking device and an emergency opening device are all designed on the chassis vehicle, thus the operation is reliable and the cooperation precision is high.

Background technology
Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application, and the high-low pressure identification of boundaries is fuzzyyer, and is general with the High-Voltage Electrical Appliances that are called more than the 3kV.Low-voltage circuit breaker is claimed automatic switch again, is commonly called as " air switch " and also is meant low-voltage circuit breaker, and it is a kind of existing hand switch effect, can carry out decompression, under-voltage, overload and the electrical equipment of short-circuit protection again automatically.It can be used to distribute electric energy; Do not start asynchronous motor continually; Power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally need not change parts, obtained to use widely.
Application number is that 200720043574 patent application document discloses a kind of Chassis truck two-in-one interlock device; Include fixed cross beam, fixed cross beam is provided with the vacuum circuit-breaker action bars and passes the hole, it is characterized in that: the lateral surface of described crossbeam is provided with baffle plate; This baffle plate is provided with the through hole that supplies the vacuum circuit-breaker operating grip to pass; Be provided with procedure lock on the described crossbeam in addition, the moving of this procedure lock control baffle plate, constitute on the baffle plate through hole with pass the hole over against cooperating with misplacing.But also there are some rooms for improvement in this technical scheme, and urgent switching-off device is not set.
In sum, to the defective of prior art, need a kind of especially with closing the chassis device of door operation, with the problem of mentioning more than solving with urgent separating brake.
The utility model content
It is a kind of with closing the chassis device of door operation with urgent separating brake that the purpose of the utility model is to provide, and through an interlock is set on chassis, thereby realizes the purpose of the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of with closing the chassis device of door operation with urgent separating brake, comprise chassis, crossbeam, left jam plate, handle welded plate, leading screw, right jam plate and slider roller; Said left jam plate, right jam plate lay respectively at the left and right sides of handle welded plate; And pinning the handle welded plate, said slider roller can drive left jam plate and right jam plate moves, and the handle welded plate can be moved backward; Handle can insert in the screw mandrel; It is characterized in that thereby circuit breaker can be shaken into shake out said chassis device is equipped with the interlock of a built-in sliding bar, sliding bar can tangle the locking part that is positioned on the cabinet door.
In an embodiment of the utility model, said chassis device also is provided with the emergency unlocking device that has the axial rotation structure.
The beneficial effect of the utility model is: simple in structure, design ingenious, will close door operation, interlock and urgent switching-off device all design on chassis, make operation more reliable, quality of fit is higher.
Description of drawings
Fig. 1 is the chassis schematic representation of apparatus that the described band of the utility model closes door operation and urgent separating brake.
Fig. 2 is the profile that the described band of the utility model closes the door operation and the chassis device of urgent separating brake.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, the utility model is described a kind of with closing the chassis device of door operation with urgent separating brake, comprises chassis 1, crossbeam 2, left jam plate 4, handle welded plate 5, leading screw 6, right jam plate 7 and slider roller 9; Said left jam plate 4, right jam plate 7 lay respectively at the left and right sides of handle welded plate 5, and pin handle welded plate 5, and said slider roller 9 can drive left jam plate 4 and right jam plate 7 move left and right; Said slider roller can drive left jam plate and right jam plate moves; The handle welded plate can be moved backward, and handle can insert in the screw mandrel, shakes thereby circuit breaker can be shaken into; Said chassis device is equipped with the interlock 8 of a built-in sliding bar, and sliding bar can tangle the locking part that is positioned on the cabinet door.
In an embodiment of the utility model, said chassis device also is provided with the emergency unlocking device 3 that has the axial rotation structure.
The operation principle of the utility model is following: left jam plate 4 pins handle welded plate 5 with right jam plate 7.Handle welded plate 5 can not be moved backward, thus crank handle can't be inserted in the rotary screw rod 6, so the chassis dolly can't advance or retreat.Only after slider roller 9 was pushed open by the push pedal above the switch cubicle door, handle welded plate 5 could move backward, and handle is inserted in the leading screw 6, and the actuating chassis is shaken into and shaken out.When the chassis bottom plate apparatus slowly leaves test position through lead screw transmission; Sliding bar in the interlock 8 will with slowly expose interlock; Thereby tangle the locking part above the cabinet door; Circuit breaker door of switch cabinet after leaving test position can not be opened, thereby guarantee the fail safe of operation.If circuit breaker in the service position emergency episode takes place, comprehensive guarantor can't give the breaker open operation signal, need be when manually carrying out separating brake, and spend and can make breaker open operation as long as urgent switching-off device 3 is rotated 20 to counter clockwise direction.
The beneficial effect of the utility model is: simple in structure, design ingenious, will close door operation, interlock and urgent switching-off device all design on chassis, make operation more reliable, quality of fit is higher.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
