Description
Technical field
The utility model relates to a kind of screw rod open-close sluice gate protective devices, belong to Automatic controlling of strobe equipment technical field.
Background technique
Currently, the lower-limit point control for screw open-close machine all relies on lower limit machinery or electronic switch, and lower limit is mechanical
Or electronic switch only works as gate and has arrived after bottom position the control action that can just play stopping, having stone etc. different below gate
In the case that object or gate are stuck, gate is unable to run bottom position, and lower limit is mechanical or electronic switch is ineffective, control cabinet
Because confiscating stop signal without cutting off the power, the result is that motor continues to rotate, cause to gate, headstock gear, screw rod
Permanent damage.
Summary of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of screw rod open-close sluice gate protective device, it can
Realize that gate caused by stuck gate or there is foreign matter in lower section can not drop to the protection of bottom end, without manually checking, structure letter
It is single, cost can be reduced, gate reliability of operation is improved.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of screw rod open-close sluice gate protective device,
Including motor, gate, screw rod, headstock gear, connecting rod, the motor, gate are separately mounted to inside headstock gear up and down
Both ends；The upper end of the headstock gear is provided with a through-hole；The screw rod stretches to inside headstock gear from through-hole, further includes
Conducting wire, the spring case being connect with screw rod and the spring for touching plate, being mounted on inside spring case, the side installation of the spring case
There is travel switch, the other side is equipped with signal transfer means；One end of the connecting rod and the low side of spring case connect, another
End is connect with gate；The upper end of the headstock gear is equipped with signal receiving device；The signal receiving device passes through conducting wire
It is connect with control cabinet.
Preferably, the plate that touches is connected by screw bolts or is clamped with screw rod.
Preferably, wireless transmission method is used between the signal transfer means and signal receiving device.
Preferably, one end of the connecting rod uses with gate and is threadedly coupled.
It preferably, further include connector, one end of screw, the connector is fixedly connected by screw with screw rod, separately
One end is held out against in spring upper end, and the spring is fixed on the interior lower end surface of spring case.
The beneficial effects of the utility model are: compared with prior art, the utility model it is mountable screw rod and gate it
Between junction, when gate is unable to run, and when screw rod continues decline, spring in screw compression spring case touches plate with spiral shell
After bar continues 1-2 centimetres of decline, travel switch is triggered, signal is passed to transmitting terminal, transmitting terminal wireless transmission letter by travel switch
Number arrive receiving end, receiving end relay output, cut off motor power, screw rod stop, to protect gate, screw rod, opening and closing
Machine, structure is simple, can reduce cost, improves gate reliability of operation.

In figure: 1, motor, 2, gate, 3, screw rod, 4, headstock gear, 5, conducting wire, 6, spring case, 7, spring, 8, stroke opens
It closes, 9, touch plate, 10, signal transfer means, 11, signal receiving device, 12, connecting rod, 13, control cabinet, 14, connector.
Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.
Unless otherwise defined, all technical terms and scientific terms used herein and the skill for belonging to the utility model
The normally understood meaning of the technical staff in art field is identical, and terminology used in the description of the utility model herein is only
It is the purpose in order to describe specific embodiment, it is not intended that in limitation the utility model.
As shown in Figure 1 and Figure 2, a kind of screw rod open-close sluice gate protective device, including motor 1, gate 2, screw rod 3, headstock gear
4, connecting rod 12, the motor 1, gate 2 are separately mounted to 4 inside upper and lower ends of headstock gear；The headstock gear 4 it is upper
End is provided with a through-hole；The screw rod 3 stretches to inside headstock gear 4 from through-hole, further includes conducting wire 5, connect with screw rod 3
Spring case 6 and plate 9, the spring being mounted on inside spring case 67 are touched, the side of the spring case 6 is equipped with travel switch 8,
The other side is equipped with signal transfer means 10；One end of the connecting rod 12 is connect with the low side of spring case 6, the other end and lock
Door 2 connects；The upper end of the headstock gear 4 is equipped with signal receiving device 11；The signal receiving device 11 passes through conducting wire 5
It is connect with control cabinet 13.
The plate 9 that touches is connected by screw bolts or is clamped with screw rod 3.
Wireless transmission method is used between the signal transfer means 10 and signal receiving device 11, easily and effectively, letter
It is situated between reliable.
One end of the connecting rod 12 uses with gate 2 and is threadedly coupled.
As shown in Fig. 2, further including connector 14, one end of screw, the connector 14 is fixed by screw and screw rod 3
Connection, the other end are held out against in 7 upper end of spring, and the spring 7 is fixed on the interior lower end surface of spring case 6.
During 2 normal downlink of gate, the external force such as self weight or water resistance, friction due to gate 2 are little, in spring case 6
