Bar cohesion device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of linkage drive rod cohesion device, including two respectively from both direction clamp drive rod with realize drive rod embrace
Tight band-type brake body, described device further include two groups of springs for driving two band-type brake bodies to separate, one end difference of two groups of springs
It is connected to the inside of two band-type brake bodies, the other end is respectively connected to two stationary planes, is equipped with and passes on the inside of two band-type brake bodies
The groove of lever cooperation, surrounding are arranged with coil.
Two coils are parallel with one another and with phase coiling.
Two coils are serially connected and with phase coilings.
Described device further includes the guide rail of two restriction band-type brake body moving directions, is equipped on two band-type brake bodies for described
Guide rail wears the through-hole penetrated, and the spring is sheathed on guide rail.
For triggering and exporting the trigger switch of switching signal on one of band-type brake body, the trigger switch after combined floodgate
It is triggered under the extruding of another band-type brake body.
Two guide rails are about drive rod central symmetry.
Compared with prior art, the utility model has the following beneficial effects:
1) it drives two band-type brake bodies to be attracted by electromagnetic mode, realizes the automatic holding drive rod of linkage property, do not need
It is artificial to go to control whether to need to close the plug-in strip of contact net, while also not needing complicated steering mechanism and linkage can be realized.
2) moving direction that band-type brake body is shown by guide rail, improves stability.
Detailed description of the invention

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
A kind of linkage drive rod cohesion device, as depicted in figs. 1 and 2, including two clamp transmission from both direction respectively
For bar 6 to realize band-type brake body 3 that drive rod 6 is held tightly, device further includes two groups for the springs 2 that drive two band-type brake bodies 3 isolated, and two
One end of group spring 2 is respectively connected to the inside of two band-type brake bodies 3, and the other end is respectively connected to two stationary planes, two band-type brakes
The inside of body 3 is equipped with the groove cooperated with drive rod 6, and surrounding is arranged with coil.
It drives two band-type brake bodies to be attracted by electromagnetic mode, realizes the automatic holding drive rod of linkage property, be not required to very important person
For go control whether to need to close the plug-in strip of contact net, while not needing complicated steering mechanism yet and linkage can be realized.
In specific implementation, it is parallel with one another and with phase coiling to can be two coils, is also possible to two coils and is serially connected
And with phase coiling, but the power supply no matter connected is DC power supply, is illustrated in figure 3 schematic diagram when two coils from parallel connection of coils, and E is electricity
Source, R are resistance, and L1 and L2 are respectively two coils, and when energized, two band-type brake bodies 3 are magnetized, since direction is identical, magnetic
It is attracting both after change.
Preferably, two coils can have two groups of power supply circuits, in another group of power supply circuit, two coils be reversely around
System, so when energized, two band-type brake bodies 3 are magnetized, and due to contrary, repel each other both after magnetization.
Device further includes the guide rail 4 of two restriction 3 moving directions of band-type brake body, and two guide rails 4 are about 6 center pair of drive rod
Claim, is equipped on two band-type brake bodies 3 and wears the through-hole penetrated for guide rail 4, spring 2 is sheathed on guide rail 4.
For triggering and exporting the trigger switch 5 of switching signal on one of band-type brake body 3, which is closing a floodgate
It is triggered under the extruding of another band-type brake body 3 afterwards.
The stationary plane of specific one group of spring 2 connection is fixing bracket body 1, and the stationary plane of another group of connection is then steel plate composition
8, it connect side with band-type brake body 3 and is connected by fixed block 7.
Above-mentioned cohesion device can detect whether cohesion device is held tightly by trigger switch, and spring 2 can guarantee connecing
It is unclamped by cohesion device after signal.
Band-type brake body 3 holds 6 body of drive rod tightly because magnetic force close to each other is generated, and power-off magnetic force disappears then will by spring
Band-type brake magnet retracts, and releases band-type brake.
Specific work process is as follows:
1, band-type brake process: after band-type brake body 3 receives signal, two band-type brake bodies 3 generate magnetic force close to each other, Xiang Chuandong
6 direction of bar is drawn close, until drive rod 6 is embraced, is able to rotate drive rod 6 not or play, while contacting touch switch 5, defeated
Band-type brake completes signal out.
2, release process: after two band-type brake bodies 3 receive another signal, a kind of situation is repelled each other by spring tension,
Another situation is that two band-type brake bodies 3 generate the magnetic force being located remotely from each other, and it is mobile to 6 two sides of drive rod, cancel the system to drive rod 6
It is dynamic, rotate drive rod 6 or play, while unclamping touch switch 5, output band-type brake unclamps signal.
