Abstract
A kind of automatic electric brake for preventing from accidentally touching, including plug-in strip group, the first contact sets, second contact sets, the plug-in strip group are set on horizontal axis, and the horizontal axis both ends are matched with arc-shaped slide rail and walking arm, walking arm is provided with screw, and screw is matched with lead screw, and lead screw matches power unit.The present invention is driven using screw rod and screw, is kept the adjustable extent for acting speed when plug-in strip group double-throw contact wider, is generated the case where accidentally touching because of a period of time operation error to substantially reduce.
Description
Technical field
The present invention relates to a kind of electric switchgear, in particular to a kind of automatic electric brake for preventing from accidentally touching.
Background technique
Electric brake is a kind of common current switching equipment, is frequently utilized among large scale equipment or total lock, with science and technology
Development and people's awareness of safety raising, more and more installations and facilities use automatic electric brake, and existing automatic electric brake is more
Using relay construction, failure rate is low, and long-time service is also able to maintain high reliability, but relay response speed is exceedingly fast,
This kind of utilization rate of electric brake it is low, accidentally become after touch as a big disadvantage on the relatively serious switchgear of fruit.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of automatic electric brake for preventing from accidentally touching.
The technical solution adopted by the present invention is that: a kind of automatic electric brake for preventing from accidentally touching, including plug-in strip group, the first contact sets,
Second contact sets, the plug-in strip group are set on horizontal axis, and the horizontal axis both ends are matched with arc-shaped slide rail and walking arm, and walking arm is set
It is equipped with screw, screw is matched with lead screw, and lead screw matches power unit.
A kind of automatic electric brake for preventing from accidentally touching, it is characterized in that: the walking arm is provided with vertical guide groove, institute
It states plug-in strip group to be articulated on horizontal axis, the horizontal axis end is set in the guide groove.
A kind of automatic electric brake for preventing from accidentally touching, it is characterized in that: being set between first contact sets, the second contact sets
It is equipped with intermediate contact group.
The present invention is driven using screw rod and screw, keeps the adjustable extent for acting speed when plug-in strip group double-throw contact wider, from
And it substantially reduces and generates the case where accidentally touching because of a period of time operation error.Intermediate contact group is set, plug-in strip group can be made two groups of contacts
Between increase a link, further decrease due to accidentally touch risk, meanwhile, intermediate contact can also play discharge process, guarantee
Safety when circuit switching.
Detailed description of the invention
Fig. 1 is one structural schematic diagram of the embodiment of the present invention；
Fig. 2 is two structural schematic diagram of the embodiment of the present invention；
In figure: 1- rack, 2- plug-in strip group, 3-the first contact sets, the second contact sets of 4-, 5- intermediate contact group, 6- connecting rod, 7- are horizontal
Axis, 8- arc-shaped slide rail, 9- walking arm, 91- guide groove, 10- screw, 11- screw rod, the first bevel gear of 12-, 13- motor, 14-
Two bevel gears.
Specific embodiment
Embodiment one:
As shown in Figure 1, a kind of prevent from missing the automatic electric brake touched, including rack 1, and setting plug-in strip group 2 in rack, the first contact sets 3,
Second contact sets 4, connecting rod 6, arc-shaped slide rail 8, screw 10, motor 13,6 one end of connecting rod is articulated in rack 1, other end installation is horizontal
Axis 7, plug-in strip group 2 are installed on horizontal axis 7, and 7 both ends of horizontal axis setting arc-shaped slide rail 8 and walking arm 9,9 upper end of walking arm are provided with U
The guide groove 91 of shape, 7 end of horizontal axis are installed in guide groove 91, and sliding rail 8 and guide groove 9 are respectively to horizontal axis 7,9 bottom of walking arm
Screw 10 is connected, screw 10 is matched with the screw rod 11 being laterally arranged, and the first bevel gear 12 is arranged in 11 one end of screw rod, and motor 13 connects
With matched second bevel gear of the first bevel gear.
When plug-in strip group needs mobile, start motor 1, drives screw rod rotation, walking arm transverse shifting, to drive plug-in strip
Group movement.
Embodiment two:
As shown in Fig. 2, a kind of prevent from missing the automatic electric brake touched, including rack 1, and setting plug-in strip group 2 in rack, the first contact sets 3,
Second contact sets 4, connecting rod 6, arc-shaped slide rail 8, screw 10, motor 13, between the first contact sets 3 and the second contact sets 4 in setting
Between contact sets 5,6 one end of connecting rod is articulated in rack 1, other end installation horizontal axis 7, and plug-in strip group 2 is installed on horizontal axis 7,7 liang of horizontal axis
End setting arc-shaped slide rail 8 and walking arm 9,9 upper end of walking arm are provided with the guide groove 91 of U-shaped, and 7 end of horizontal axis is installed on guiding
In slot 91, respectively to horizontal axis 7,9 bottom of walking arm connects screw 10 for sliding rail 8 and guide groove 9, and screw 10, which is matched with, to be laterally arranged
The first bevel gear 12, the connection of motor 13 and matched second bevel gear of the first bevel gear is arranged in screw rod 11,11 one end of screw rod.
When plug-in strip group needs mobile, start motor 1, drives screw rod rotation, walking arm transverse shifting, to drive plug-in strip
Group movement.
Assuming that the first contact sets 3 are normal power supplies, the second contact 4 is maintenance power supply.When normal power supply, plug-in strip group and the
The contact of one contact starts motor 13, plug-in strip group is switched to the second contact, has been overhauled when line failure needs to overhaul
Bi Houzai switches back into the first contact, and in example 2, plug-in strip group is contacted with intermediate contact group in electric brake handoff procedure, can be in
Between limit switch or setting related electric control program are set at contact, make plug-in strip group motor stopping when contacting intermediate contact group, from
And prevent in the inspection of line or maintenance personnel accidentally touching powers on accident occurs, meanwhile, intermediate contact can also play electric discharge
Effect makes it at two aspect of logical AND physics while preventing unexpected generation.
