Abstract
The utility model discloses a travel switch device for a high-voltage switch cabinet, which comprises a support and a cover. A support is fixed at the rear end of the support, a microswitch is fixed at the front end of the support, a contact linkage rod is fixed on the support, the rear end of the contact linkage rod penetrates out of the rear end of the support, the front end of the contact linkage rod is connected with a rear end contact point of the microswitch through a linkage plate, and one end of the linkage plate is fixed on the support. The travel switch has the advantages that travel contact can be expanded, the travel switch is small in volume and convenient in installation, action reliability is guaranteed due to the fact that only one mechanical transmission output point is connected to the external, and accordingly error in manual installation is avoided.
Description
Technical field
The utility model relates to a kind of switching device, specifically a kind of high-tension switch cabinet stroke switchgear.
Background technology
Travel switch is a kind of of position switch (claiming limit switch again), is a kind of little electric current master control electrical apparatus commonly used.Utilize the collision of manufacturing machine moving component that its contact is moved and realize connecting or the disjunction control circuit, reach certain control purpose.Usually, this class switch is used to the position or the stroke of limit mechanical motion, make movable machinery by certain position or stroke stop automatically, counter motion, variable motion or back and forth movement etc. automatically.
In electric control system, the effect of position switch is the detection that realizes sequential control, positioning control and location status, is used to control the stroke and the position limitation protection of plant equipment.Its structure is generally by operating head, contact system and shell to be formed.
In actual production, travel switch is installed in prearranged position, during module impact stroke switch on being loaded on the manufacturing machine moving component, the action of the contact of travel switch realizes the switching of circuit.Therefore, travel switch be a kind of according to moving component travel position and the electrical equipment of commutation circuit, its action principle and button are similar.
Travel switch is widely used in all kinds of lathes and hoisting machinery, in order to control its stroke, to carry out the terminal position limitation protection.In the control circuit of elevator, speed, automatic opening and closing door spacing of also utilizing travel switch to come the control switch gate, the upper and lower spacing protection of car.
Travel switch can be installed in that static relatively object (as fixed mount, doorframe etc., be called for short still life) is gone up or the object of motion (, being called for short animal) as driving, door etc. on.When animal during near still life, the contact of the connecting rod driving switch of switch causes the closed contact disjunction or the junction closure of disconnection.The action of going to control circuit and mechanism by the change of make and break contact opening and closing state.
Trolley type high voltage switch cabinet is because need electrical interlocks and the contact point signal transmission, travel switch is frequently used, but sometimes because the stroke contact is not enough, need add travel switch in addition, but so can increase its occupied space undoubtedly, and a plurality of Mechanical Contact points cause the error of action easily, and reliability reduces greatly.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides a kind of stroke contact to expand, and volume is little, high-tension switch cabinet stroke switchgear easy for installation.
To achieve these goals, the utility model adopts following technical scheme:
The high-tension switch cabinet stroke switchgear, it comprises support and lid, rear end at described support is fixed with supporter, front end at described supporter is fixed with sensitive switch, be fixed with a contact gangbar on the described supporter, the rear end of described contact gangbar passes the rear end of described support, and the front end of described contact gangbar is connected with the back termination contact of described sensitive switch by an interlock plate, and an end of described interlock plate is fixed on the described support.
Described contact gangbar is made of gangbar and back-moving spring, the front end of described gangbar passes described supporter, the rear end of described gangbar is passed described support and is fixed on the described support by a boss, described back-moving spring is sleeved on the described gangbar, one end of described back-moving spring is against on the described supporter, and the other end of described back-moving spring is against on the boss of described gangbar rear end.
The front end of described gangbar is provided with the gap transfer screw that is used to adjust the stroke gap.
The high-tension switch cabinet that the utility model provides has following advantage with stroke switchgear: the stroke contact can be expanded; Volume is little, and is easy for installation; A machine driving output point is external, has guaranteed the reliability of action, has avoided the error of artificial installation.
Description of drawings
Fig. 1 is the side-looking structural representation of an embodiment of the present utility model.
Fig. 2 is the plan structure schematic diagram of an embodiment of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth execution mode of the present utility model.
As depicted in figs. 1 and 2, high-tension switch cabinet stroke switchgear of the present utility model, it comprises support 2 and lid 1, be fixed with supporter 4 in the rear end of described support 2, front end at described supporter is fixed with sensitive switch 3, be fixed with a contact gangbar 5 on the described supporter 4, the rear end of described contact gangbar 5 passes the rear end of described support 2, the front end of described contact gangbar 5 is connected with the back termination contact of described sensitive switch 3 by an interlock plate 6, and an end of described interlock plate 6 is fixed on the described support 2.
Described contact gangbar 5 is made of gangbar 501 and back-moving spring 502, the front end of described gangbar 501 passes described supporter 4, the rear end of described gangbar 501 is passed described support 5 and is fixed on the described support 2 by a boss, described back-moving spring 502 is sleeved on the described gangbar 501, one end of described back-moving spring 502 is against on the described supporter 4, and the other end of described back-moving spring 502 is against on the boss of described gangbar 501 rear ends.
The front end of described gangbar 501 is provided with the gap transfer screw 7 that is used to adjust the stroke gap.
External force passes to interlock plate 6 by gangbar 501, swing by interlock plate 6 promotes the switching of sensitive switch 3 actions carrying out contact, gangbar 501 reposition automatically under back-moving spring 502 effects after external force is removed, sensitive switch 3 automatically resets, described sensitive switch 3 is side by side one group, totally four, formation four is opened four and is closed structure.
In the present embodiment, sensitive switch is one group ten, and formation ten is opened ten and is closed structure side by side, and all the other are with embodiment 1.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
