Abstract
The utility model relates to the technical field of a vacuum circuit breaker, in particular to a power-driven chassis truck of the vacuum circuit breaker. The power-driven chassis truck of the vacuum circuit breaker comprises a chassis truck frame, wherein the chassis truck frame is provided with a motor, a clutch and a lead screw; the motor is connected with the clutch; the other end of the clutch is connected with the lead screw; the chassis is also provided with a manual prior device for security concerns, a test position switching device and a working position switching device, wherein the manual prior device for security concerns is provided with a micro switch and a drive rod installed below the micro switch; the other end of the drive rod is connected with the lead screw; during manual operation, the micro switch on the manual prior device is immediately switched off; and thus a motor loop is cut off, so power-driven operation can not be carried out. In the power-driven chassis truck of the vacuum circuit breaker, a bevel gear driving mode is adopted, a dedicated clutch is arranged and can automatically disconnect during clamping stagnation, and thus the motor is idle. Meanwhile, the problem of zero position can be avoided by the structure, and the power-driven chassis truck can be switched manually or switched in a power-driven mode at any position.
Description
Technical field
The utility model relates to the technical field of vacuum circuit-breaker, especially a kind of electric chassis truck of vacuum circuit-breaker.
Background technology
Electric chassis truck in the market has two kinds of kinds of drive, a kind of is to adopt the Bevel Gear Transmission mode, is furnished with special clutch, when clamping stagnation occurring, clutch is thrown off automatically, motor idle running, and rely on the Current Control electric handcart of driver module to automatically revert to " test " position, when electric operating, leading screw is motionless, and bevel gear is rotated; When manual operation, leading screw rotates, and bevel gear is motionless.The shortcoming that this class kind of drive exists is when cutting off the power supply midway, can not manually shake back test position, otherwise the zero-bit sideslip, can't work, arrange in a jumble, the manual priority function is arranged, but reliability is not high.
Another kind is to adopt chain transmission mode, is furnished with special clutch, by obtaining signal, convert with displacement and to control the deceleration of motor near switch, and during the electric and hand operation, all be that leading screw rotates.The shortcoming that this class kind of drive exists be all electrical controls all by S8, S9 switch, taken one group of S8, S9 contact, the number of connections that can use of user has reduced like this, the while then can't be operated no manual priority function as if S8, S9 malfunctioning switch.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of can be electronic, the electric chassis truck of the vacuum circuit-breaker of manual switchover.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric chassis truck of vacuum circuit-breaker, adopt the kind of drive of bevel gear, comprise the chassis vehicle carriage, the chassis vehicle carriage is provided with motor, clutch and screw mandrel, motor is connected with clutch, the other end of clutch connects screw mandrel, also be provided with manual priority device, test position switching device shifter and service position switching device shifter on the described chassis, described manual priority device has sensitive switch, be installed in the drive link of sensitive switch below, the other end of drive link is connected with screw mandrel.
Described manual priority device, test position switching device shifter and service position switching device shifter by screw on the vehicle carriage of chassis.
The beneficial effects of the utility model are: the utility model adopts the Bevel Gear Transmission mode, is furnished with special clutch, when clamping stagnation occurring, clutch can be thrown off automatically, motor idle running, there is not the zero-bit problem in this kind structure simultaneously, and the optional position can electronic, manual switchover.The test position switching device shifter and the service position switching device shifter that are provided with need not to take S8, S9 contact.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. chassis vehicle carriage, 2. motor, 3. clutch, 4. screw mandrel, 5. manual priority device, 5-1. sensitive switch, 5-2. drive link, 6. test position switching device shifter, 7. service position switching device shifter.
Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The electric chassis truck of vacuum circuit-breaker as shown in Figure 1, adopt the kind of drive of bevel gear, comprise chassis vehicle carriage 1, chassis vehicle carriage 1 is provided with motor 2, clutch 3 and screw mandrel 4, motor 2 is connected with clutch 3, the other end of clutch 3 connects screw mandrel 4, also be provided with manual priority device 5 on the chassis vehicle carriage 1, test position switching device shifter 6 and service position switching device shifter 7, manual priority device 5 has sensitive switch 5-1, be installed in the drive link 5-2 of sensitive switch 5-1 below, the other end of drive link 5-2 is connected with screw mandrel 4, manual priority device 5, test position switching device shifter 6 and service position switching device shifter 7 by screw on chassis vehicle carriage 1.
The work of motor 2 solenoidoperated cluthes 3, clutch 3 drives screw mandrels 4 and rotates, and just can realize that circuit breaker cart realizes distant place electric operating turnover cabinet under the situation of " unmanned " at the scene, send electric work to finish complete stopping, and has improved operating efficiency.
During manual operation, control sensitive switch 5-1, cut off electronic electric motor loop, realize manually control by the motion of drive link 5-2, manually, electronic any switching, adopt the Bevel Gear Transmission mode, be furnished with special-purpose clutch 3, when clamping stagnation occurring, clutch 3 is thrown off automatically, motor 2 idle running; Cut off the electric loop of motor 2 by the switching of sensitive switch, to realize the deceleration purpose; Electronic, manually shake when into shaking out, rotate by leading screw 4 and control the exchange that test position switching device shifter 6, service position switching device shifter 7 reach test position and service position, can be because of regulating S8, S9 and losing efficacy; Do not have the zero-bit problem, the optional position can manual, electronic switching.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the present utility model.
