Specific embodiment
The utility model is described in further details for being embodied presently in connection with attached drawing:
A kind of multitool multilayer and multiposition switching switch, the switch are made of three groups of knives and three layers of knife, can form four and cut bit switch
Structure and state, three groups of knives, three layers of knife are to be fixed with a pillar on each angle in the square plane of bracket 1
9, it is respectively equipped with upper mounted plate 12 and bottom plate 13 in 9 upper and lower side of pillar, center is equipped with by bearing at the center of square
Axis 8 is uniformly provided with three groups of plug-in strips 7 on central axis 8, handwheel 10 is fixed in 8 upper end of central axis, in the lower end of central axis 8
It is equipped with motor 2 by electric control part, motor 2 is sequentially connected by freewheel clutch 14 and 8 phase of central axis, and central axis 8 drives absolutely
Three groups of plug-in strips 7 on listrium 4 and insulation board 4 and the touching reed 5 on pillar 9 are in contact；Three are respectively equipped on four pillars 9
Layer touching reed 5；Three groups of plug-in strips 7 and three layers of touching reed 5 are electrically connected respectively with external king-tower multiple groups for tower.In
Three groups of plug-in strips 7 setting corresponding with three layers of touching reed 5 being arranged on four pillars 9 in mandrel 8.
Reed 5 is touched to be arranged on pillar 9 and connect with the touching of every group of 7 phase of plug-in strip, every group of touching reed 5 by with pillar
External network or steel tower are led in the connection of conducting block 6 on 9.
Three knives, three layers of three switching in the utility model are switched by 4, three layers of an insulation board plug-in strip of central axis 8, three
7, three layers of 9, one, pillar motor, 2, handwheel 10 of touching reed 5, four and electric control part composition.Pass through external control box control
Motor 2 processed rotates to realize active and standby tower switching or active and standby network switching.The rotation of motor 2 arrives central axis 8 by freewheel clutch 14,
Central axis 8 drives the touching reed 5 on plug-in strip 7 and pillar 9 on insulation board 4 and insulation board 4 to contact.When one state standard of arrival
When true position, a travel switch 3 by being mounted on bottom plate 13 is limited, and realizes a kind of state.
When control system breaks down, switching switch will not be influenced and run well.During manual rotation's handwheel 10 drives
Mandrel 8 rotates, and disengages motor 2 by the freewheel clutch 14 with one-way function and insulation board 4 is driven to rotate, insulation board 4 drives
Plug-in strip 7 on insulation board turns to certain position and touching reed 5 contacts, and when reaching accurate location, collision bead 11 is limited.Switching
Switch realizes a state.Motor 2 is slowspeed machine, and strength is very big.By using the overdrive clutch with individual event function
Device 14 can disengage motor 2 when manual to make to become manually very easily.
Current many radio station are there is moving, if a standby tower is only built in each resettlement radio station, so that it may as
The standby tower of all main steel towers switchs changeable king-tower (by standby network) by using the switching of multitool multilayer and multiposition and arrives standby tower, from
And solve the problems, such as normal broadcast of the steel tower maintenance, repair without influencing broadcasting station, also a large amount of construction has been saved for country
The fund of steel tower and a large amount of soil.
Application of the utility model multitool multilayer and multiposition switching switch on broadcast transmission radio station.
Existing four steel towers in certain broadcasting station, three are used as king-tower, and a standby tower as three king-towers, three king-towers are each
It is equipped with a set of master and is total to tower network and a set of standby tower network altogether, standby tower network altogether is respectively standby network W1, standby network W2, standby network
W3.King-tower on main tower network altogether, for standby tower on tower network altogether.It is required that a set of switching switch of design, to switch three king-towers respectively
On (standby tower network altogether) to a standby tower.
It is required that: switch is able to achieve four kinds of states (position).
State 1: standby tower on standby network W1, standby network W2, standby network W3 are grounded.
State 2: standby tower on standby network W2, standby network W3, standby network W1 are grounded.
State 3: standby tower on standby network W3, standby network W1, standby network W2 are grounded.
State 4: standby network W1, standby network W2, standby network W3, standby tower are grounded.
If three king-towers (standby network) just need three sets of double-poles using the double-pole dibit switching switch being commonly used
On-off switch to switch with a standby tower.Switching increases switch cost in this way, automatically controlled also extremely complex.By designing a set of switching
It switchs to complete the function of three sets of double-pole on-off switches switching.Present switching switch is double-pole dibit, and contact is few, cannot complete
Three king-towers (standby network) are switched to respectively on a standby tower.It completes three king-towers (standby network) and is switched to a standby tower respectively
On, it must just increase contact, increase knife number.And single layer increases knife number and can not switch over to steel tower, this just needs to increase layer
Number is to increase knife number, Lai Zengjia contact.
Three layers four, six knife (multitool multilayer and multiposition) the switching switch of production is then able to achieve three iron in existing radio station completely
The state on a standby tower with required realization is switched between tower (standby network).
The utility model can realize that electronic, manual (a local, distant place) integrative control, signal lamp indicate in place.
Using freewheel clutch 14, freewheel clutch has the function of individual event.Slowspeed machine is selected, with the big spy of torque
Point.
Travel switch 3 limits, and manual collision bead 11 limits.Handwheel 10 is used manually, single direction rotation can be detached from motor rotation,
So that manual rotational force becomes very light.Conductive grease is smeared between plug-in strip 7 and touching reed 5, improves its service life.Machine,
