Background
The fog gun machine is equipment for removing dust and suppressing dust in a water mist spraying mode, and when the fog gun machine works, the fog gun machine needs to horizontally rotate in a reciprocating mode under the driving of a driving motor so as to expand the spraying range of water mist. At present, the horizontal reciprocating rotation of the fog gun machine is generally controlled by a PLC (programmable logic controller), the PLC detects whether the fog gun machine rotates to two limit positions in real time through a forward rotation in-place switch and a reverse rotation in-place switch, if the fog gun machine reaches the limit positions, a driving motor is stopped by controlling the on-off of two alternating current contactors, and the rotation direction of the fog gun machine is changed by changing the phase sequence of a power supply. Because frequently start and stop and change the direction of rotation, driving motor very easily damages, greatly reduced the operational reliability of equipment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fog gun is with reciprocal rotary device to prior art's drawback to reduce equipment trouble rate, improve equipment's operational reliability guarantees fog gun machine steady operation.
The problem of the utility model is solved with following technical scheme:
the utility model provides a reciprocating rotation device for fog gun, includes that rotary platform, movable platform, driving motor, power gear, cylinder and level are fixed in the frame and coaxial corotation fluted disc and reversal fluted disc each other in the constitution, rotary platform is located corotation fluted disc and reversal fluted disc top and is connected with the center pin rotation of corotation fluted disc, movable platform passes through horizontal guide rail and rotary platform sliding connection, driving motor is vertical to be fixed on movable platform, power gear be located between corotation fluted disc and the reversal fluted disc and with driving motor's output shaft coaxial coupling, the cylinder body and the piston rod of cylinder are connected with rotary platform and movable platform respectively.
In the reciprocating rotating device for the fog gun, the brake is arranged between the rotating platform and the central shaft of the positive rotation fluted disc.
The reciprocating rotation device for the fog gun further comprises a reverse rotation in-place sensor and a forward rotation in-place sensor, wherein the reverse rotation in-place sensor and the forward rotation in-place sensor are mounted on the cylinder and correspond to a piston rod of the cylinder, and signal output ends of the reverse rotation in-place sensor and the forward rotation in-place sensor are connected with a controller of the cylinder.
The utility model discloses a change the direction of rotation that the power gear changes the rotary platform who bears the weight of fog gun machine with the meshing mode of corotation fluted disc and reversal inner fluted disc, driving motor need not frequently to open and stop and change the direction of rotation to effectively prolonged driving motor's life, reduced equipment failure rate, guaranteed the steady operation of fog gun machine.

Detailed Description
Referring to fig. 1 and 2, the utility model discloses mainly include corotation fluted disc 1, reversal internal tooth dish 2, power gear 3, rotary platform 4, driving motor 5, guide rail 6, cylinder 7, reversal sensor 8 that targets in place, corotation sensor 9 that targets in place, movable platform 10 and stopper 12.
In the running process of the fog gun machine, the driving motor 5 drives the power gear 3 to stably run at a certain rotating speed, when the power gear 3 is meshed with the forward rotation fluted disc 1, the rotating platform 4 and the fog gun machine arranged on the upper portion of the rotating platform rotate forward around the central shaft 11 of the forward rotation fluted disc 1, and when the power gear 3 is meshed with the reverse rotation inner fluted disc 2, the rotating platform 4 and the fog gun machine arranged on the upper portion of the rotating platform rotate reversely around the central shaft 11 of the forward rotation fluted disc 1. The meshing of the power gear 3 and which fluted disc is controlled by the cylinder 7, the cylinder 7 can drive the movable platform 10 and the driving motor 5 installed on the movable platform 10 to do linear motion along the guide rail 6, when the piston rod of the cylinder 7 retracts, the power gear 3 is meshed with the forward rotation fluted disc 1, the fog gun machine rotates forwards, when the piston rod of the cylinder 7 extends, the power gear 3 is meshed with the reverse rotation inner fluted disc 2, the fog gun machine rotates reversely, and the power gear 3 is alternately meshed with the forward rotation fluted disc 1 and the reverse rotation inner fluted disc 2, so that the horizontal reciprocating rotation of the fog gun machine can be realized.
The horizontal reciprocating rotation of the fog gun machine is controlled by a Programmable Logic Controller (PLC), and a forward rotation in-place sensor 9 and a reverse rotation in-place sensor 8 are used for detecting the position of a piston rod of an air cylinder 7, so that whether the power gear 3 moves in place or not is judged.
The process of the PLC controlling the action of the air cylinder 7 is as follows: when the forward rotation needs to be switched to the reverse rotation (namely the power gear 3 leaves the forward rotation fluted disc 1 and is meshed with the reverse rotation inner fluted disc 2), the PLC controls the extension of a piston rod of the air cylinder 7 through the electromagnetic valve, the electromagnetic valve is closed when the forward rotation in-place sensor 9 has no signal, the air cylinder 7 stops acting, then the brake 12 acts to stop the forward rotation of the rotating platform 4, then the brake 12 is released, and the PLC enables the piston rod of the air cylinder 7 to continue to extend until the reverse rotation in-place sensor 8 has a signal, so that the meshing process is completed. When the reverse rotation is switched to the forward rotation, the cylinder is operated reversely.
The utility model discloses a driving motor need not frequently open and stop and switching power phase sequence, so can long-term steady operation to driving motor's life has been prolonged.
