Abstract
A signal trigger mechanism comprises an upper lock hole seat which is fixed on the inner walls of a door lintel beam through bolts, and a trigger type limiting switch on the upper side of the door lintel beam, wherein a trigger element for the trigger limiting switch is movably sleeved in the lock hole in the upper lock hole seat, the mechanism comprises a spring which is used to drive the trigger element to reset. When a lock pin is inserted in the lock hole, the trigger element is pushed to move, and the spring is compressed simultaneously, and the trigger element is moved to reset under the effect of the spring when the lock pin is retreated from the lock hole. The movement of the trigger element can activate the limiting switch, thereby collecting the closing and opening state signals to each door unit of system. The signal trigger mechanism has the advantages of simple structure, convenient processing, installation and maintenance, and reliable and stable performance.
Description
Technical field
The utility model relates to a kind of signal trigger mechanism that is used for subway shield door system.
Background technology
Subway shield door system all adopts automatic control system to come the control appliance operation, for guaranteeing safety, in use require the open and close situation of each gate cell of grasp system, the open and close door status signal that so just needs reliable each gate cell of gathering system, therefore needing a kind of mechanism can reliably trigger the limit switch of control system, thereby finishes the collection of open and close door information.
Practical emerging content
The utility model is in order to solve above-mentioned technical problem, proposes a kind ofly when each gate cell open and close door of system, can trigger the trigger mechanism of limit switch.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of signal trigger mechanism of structure, comprise through the last lock hole seat of bolt on lintel beam inwall, be located at the trigger-type limit switch of lintel beam upside, kink is useful on the triggering part that triggers limit switch in the lockhole of last lock hole seat, also comprises driving triggering the spring that part resets.
Wherein, described lockhole is made of large aperture section that is positioned at downside and the small-bore section that is positioned at upside, trigger part and comprise the signal lever axle of kink in the section of large aperture, the bottom penetrates terminal and signal lever male thread connection all-in-one-piece signal lever in the lockhole, it is corresponding with limit switch that the top of signal lever passes lintel Liangqi top, spring is set on the signal lever, and the upper and lower end of spring is resisted against respectively on the step surface and signal lever axle upper surface of lockhole.
The described lock hole seat of going up is provided with stopper slot, and the shaft of signal lever is provided with the stop screw that inserts in the stopper slot.
Be fixed with the supporting plate of a bending on the described lintel beam, limit switch is fixed on the supporting plate erection part, and the erection part of supporting plate is provided with the vertical slot for the upper and lower mobile adjusting level altitude of limit switch.
Be provided with the adjustment shim between the beam wall of described upward lock hole seat and lintel beam.
The utility model installs in the lockhole of last lock hole seat and triggers part, promotes to trigger part when lock pin inserts lockhole and moves, and spring was compressed when the triggering part moved; When lock pin withdraws from lockhole, trigger part mobile resetting under the spring force effect.Trigger moving of part and can trigger limit switch, thereby collect the open and close door status signal of each gate cell of system.The utlity model has simple in structure, processing, install, safeguard easily, advantage stable and reliable for performance.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, wherein:
Fig. 1 is the structural representation of the utility model preferred embodiment.
The specific embodiment
Fig. 1 shows the basic structure of the utility model preferred embodiment, a kind of signal trigger mechanism, comprise through the last lock hole seat 2 of bolt on lintel beam 1 inwall, be located at the trigger-type limit switch 3 of lintel beam 1 upside, kink is useful on the triggering part that triggers limit switch 3 in the lockhole of last lock hole seat 2, also comprises driving triggering the spring 4 that part resets.In the present embodiment, lockhole is made of large aperture section that is positioned at downside and the small-bore section that is positioned at upside, trigger part and comprise the signal lever axle 5 of kink in the section of large aperture, the bottom penetrates terminal and signal lever axle 5 spiral marking connection all-in-one-piece signal leveves 6 in the lockhole, it is corresponding with limit switch 3 that the top of signal lever 6 passes lintel beam 1 its top, spring 4 is set on the signal lever 6, and the upper and lower end of spring 4 is resisted against respectively on the step surface and signal lever axle 5 upper surfaces of lockhole.
In the present embodiment, last lock hole seat 2 is provided with stopper slot 7, and the shaft of signal lever 6 is provided with the stop screw 8 that inserts in the stopper slot 7.The stop screw 8 that inserts in the stopper slot 7 plays barrier effect, and the signal lever 6 and the displacement of signal lever axle 5 are restricted, signal lever 6 and the length decision of signal lever axle 5 maximum moving distances by stopper slot 7.For adjusting lock hole seat 2 positions, make signal lever 6 can aim at limit switch 3, be provided with between the beam wall of last lock hole seat 2 and lintel beam 1 and adjust shim 10 (with reference to Fig. 1).
In the present embodiment, be fixed with the supporting plate 9 of a bending on the lintel beam 1, limit switch 3 is fixed on supporting plate 9 erection part, and the erection part of supporting plate 9 is provided with the vertical slot (not shown) for limit switch 3 upper and lower mobile adjusting level altitudes.As shown in Figure 1, limit switch 3 afterbodys are provided with a screw rod, and after the screw rod of limit switch 3 passed the vertical slot of supporting plate 9, it was also tight mutually with limit switch 3 and supporting plate 9 to load onto nut, and limit switch 3 is fixed on the upstanding portion of supporting plate 9.When need regulating limit switch 3 height of living in, can unscrew nut, move limit switch 3, screw nut during to desired height along vertical slot.
