Description
Technical Field
The utility model belongs to the technical field of continuous casting flame cutting machine equipment, a square billet caster flame cutting car flywheel formula cutting gun swing arm device is related to.
Background
The cutting gun of the continuous casting machine casting blank flame cutting machine is driven by a motor, the traditional mode is that the motor is driven in the forward direction and is driven by a reduction gearbox gear, and then the cutting action is completed by directly connecting an output shaft to a swing arm of the flame cutting gun. The actual working process of the cutting gun is as follows: the method comprises the steps of firstly waiting for a cutting start signal at an initial original limit position set by a cutting gun in an automatic working state, starting a motor to drive a reduction gearbox to transmit when the initial cutting signal arrives, driving a gun pendulum device to walk and cut a casting blank (the width of the casting blank is 170 mm) by taking a shaft sleeve as a circle center and taking a gun rod length (about 1.5 m) as a radius, setting a cutting finish stop limit at a position 190mm away from the original limit position, sending a stop signal when the motor drives the gun pendulum device to cut the casting blank and contact the stop limit, stopping forward operation of the motor, delaying for 2 seconds, then reversely operating the motor, and simultaneously driving the gun pendulum device to return to the original limit position to stop waiting for a next cutting signal. In the whole cutting process, if the stopping limit fails and a stop signal cannot be sent out, the forward running of the motor cannot be normally stopped, so that the gun pendulum device is pushed to the cutting vehicle body beyond a preset stop position and is damaged, even the motor is seriously blocked, the motor is burnt due to large motor load current, and the casting production is stopped due to the accident. When the gun is stopped for limiting adjustment or the motor is replaced for rush repair, personnel are in a severe environment with high-temperature radiation and splashing cutting steel scraps, the maintenance operation difficulty is high, the safety of the personnel cannot be effectively guaranteed, the number of times of adjusting the original position of the gun per operation class reaches 7-8 times, and the working strength is high.
SUMMERY OF THE UTILITY MODEL
In order to solve the shortcoming in the prior art, the utility model provides a square billet caster flame cutting car flywheel formula cutting gun swing arm device can be when spacing inefficacy, and the cutting gun surmounts under the fault condition of stroke continuation operation, and the device can effective protective apparatus according to the distinctive performance of flywheel gear, avoids the fault amplification, ensures simultaneously that production continues steady operation, reduces workman intensity of labour.
The utility model provides a technical scheme that its technical problem adopted is: a flywheel type cutting gun swing arm device of a flame cutting vehicle of a billet caster comprises a driving gear, a driven gear, a flywheel gear, a cutting gun and a cutting gun shaft sleeve; the driving gear is connected with the driven gear in a power mode, the driving gear drives the driven gear to rotate, and the driven gear drives the cutting gun shaft sleeve to move through the flywheel gear.
The cutting gun is arranged in the cutting gun shaft sleeve and is driven by the cutting gun shaft sleeve to move downwards for cutting.
The driving gear is installed at the speed reducer drive shaft, and the speed reducer drive shaft is located drive speed reducer output.
And the driving speed reducer is in power connection with the driving motor.
The utility model has the advantages that: when the limit is invalid, under the fault condition that the cutting gun continuously operates beyond the stroke, the device can effectively protect equipment according to the unique performance of the flywheel gear, avoid fault expansion, ensure continuous and stable operation of production and reduce the labor intensity of workers.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a side view of the present invention;
in the figure: 1-driving motor, 2-driving reducer, 3-reducer driving shaft, 4-driving gear, 5-driven gear, 6-flywheel gear, 7-cutting gun shaft sleeve and 8-cutting gun.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, a flywheel type cutting gun swing arm device of a flame cutting vehicle of a billet caster comprises a driving gear 4, a driven gear 5, a flywheel gear 6, a cutting gun 8 and a cutting gun shaft sleeve 7; wherein the rotating shaft on one side of the flywheel gear 6 is connected with the driven gear 5, the rotating shaft on the other side of the flywheel gear 6 is connected with the cutting gun shaft sleeve 7, the driving gear 4 is in power connection with the driven gear 5, the driving gear 4 drives the driven gear 5 to rotate, and the driven gear 5 drives the cutting gun shaft sleeve 7 to move through the flywheel gear 6.
The cutting torch 8 is installed in the cutting torch shaft sleeve 7 and is driven to move downwards to cut by the cutting torch shaft sleeve 7.
The driving gear 4 is installed at the speed reducer driving shaft 3, and the speed reducer driving shaft 3 is located at the output end of the driving speed reducer 2.
And the driving speed reducer 2 is in power connection with the driving motor 1.
Cutting torch 8 waits for cutting signal at former spacing during normal operating condition, cutting torch driving motor 1 starts and drives 2 forward operations of drive speed reducer after obtaining the cutting signal instruction, speed reducer drive shaft 3 drives 4 forward operations of drive shaft driving gear, thereby drive shaft driven gear 5 is driven the rotation of operation drive flywheel gear 6 simultaneously and drives cutting torch 8 and cut the casting blank along the cutting direction, cutting torch 8 walks and finishes for the cutting when stopping spacingly, cutting torch 8 returns former spacing, wait for next cutting instruction. When the termination limit fails, the cutting gun driving motor 1 cannot normally stop running due to the fact that a stop signal is not received, the cutting gun 8 continues running and runs to push against a cutting vehicle body, at the moment, because the cutting gun driving motor 1 does not stop working, the flywheel gear 6 of the flywheel device which is rotated by the cutting gun driving motor 1 simultaneously starts to rotate in an idling mode along the forward direction, the cutting gun 8 is in a static state due to the fact that the flywheel gear 6 does not work any more under the driving force action of the cutting gun driving motor 1, and therefore the cutting gun 8 and the cutting gun driving motor 1 cannot be suppressed to damage a gun pendulum device due to the termination limit failure and cause motor burnout accidents due to rotation blockage.
Advantageous embodiments
The utility model provides a when stopping spacing damage inefficacy back, cutting torch 8 and the impaired problem of cutting torch driving motor 1. The flywheel device can effectively protect equipment from being continuously damaged, avoids equipment fault expansion, and has the advantages of ensuring safe and stable production operation, reducing labor intensity of workers and reducing equipment damage cost.
