Further, in this embodiment, the lower fixed pulley and the upper fixed pulley are arranged to be offset from each other in the vertical direction.
The driving mode of the fire cutting trolley is that a frequency converter is used for driving a motor, wheels on two sides of the trolley are driven to walk on a fixed walking track through a speed reducer and a driving shaft, firstly, a fire cutting trolley box body and the track are transformed, a draw hook or a lock catch is added on the rear side of the box body, a stop block is added at the origin of the tail parts of the track on two sides of the fire cutting trolley, then a supporting upright post is arranged on the basis of a trolley platform near the original site of the tail part of the fire cutting trolley, an upper fixed pulley and a lower fixed pulley are added on the supporting upright post, one end of a hoisting steel wire rope is connected to the lock catch of the tail part of the fire cutting trolley, and the other end of the hoisting steel wire rope is connected with a balancing weight.
The fire cutting trolley is provided with a fire cutting fixed-length system, a continuous casting billet head is detected in real time and tracked through an infrared camera and a fixed-length cutting software system, when the continuous casting billet head reaches a set fixed-length, a cutting signal is sent out, then a clamp electromagnetic valve is controlled through PLC output, a fire cutting machine clamp clamps the continuous casting billet through a cylinder to start to walk together, the fire cutting trolley is in a static state relative to the running continuous casting billet, when the fire cutting trolley finishes cutting the continuous casting billet, the PLC controls to send out a cutting completion signal, the clamp is loosened at the moment, and the fire cutting trolley returns to the original position after starting.
The control process of the in-situ composite accurate positioning device of the square billet flame cutting trolley is as follows:
when the fire cutting trolley is cut, the trolley motor band-type brake is opened, the trolley starts to retreat at a constant speed under the combined action of motor driving and the gravity of the configuration block, and when the fire cutting trolley retreats to detect deceleration limit (the related limit sensors all utilize original equipment), the fire cutting trolley motor stops running, but at the moment, the fire cutting trolley motor band-type brake is opened, the fire cutting trolley continues to retreat under the action of gravity of the balancing weight until the trolley travelling wheel touches a stop block arranged at the original point of the fire cutting trolley, and the fire cutting trolley can be ensured to accurately stop at the fixed original point each time due to the continuous action of gravity of the balancing weight.
In actual operation, when the fire cutting trolley is cut, the motor band-type brake of the fire cutting trolley is opened, at the moment, the fire cutting trolley is separated from a stop block of the original position of the fire cutting trolley by about 1.62 m, the trolley starts to retreat at a constant speed (the speed is about 0.2 m/s) under the combined action of the motor drive and the weight balancing weight, when the trolley retreats to detect the speed reduction limit, the fire cutting trolley is separated from the fixed stop block of the original position of the fire cutting trolley by about 0.2 m, the motor of the fire cutting trolley stops running, but at the moment, the motor band-type brake of the fire cutting trolley is opened, the fire cutting trolley continues to retreat under the action of the weight balancing weight (the speed is about 0.1 m/s) until the trolley travelling wheel touches the stop block of the original position of the fire cutting trolley, and the weight balancing weight continues to act, so that the fire cutting trolley can be accurately stopped at the fixed original position each time.
Weight determination of balancing weights of in-situ accurate positioning devices of small square billet fire cutting trolley: the weight value of the balancing weight is critical from the tracking observation in the use process, and because friction force of a sliding rail of each fire cutting trolley and flexibility of wheels of the trolley are inconsistent, when the weight of the balancing weight is lighter, the later-stage balancing weight independently acts to drive the fire cutting trolley, the situation that the trolley is dragged to retreat by small Che Ma force is not overcome, when the balancing weight is heavier, the situation that the converter is required to brake to run to counteract the gravity of the balancing weight and the current is larger in the retreating process under the combined action of the driving of the earlier-stage motor and the configuration gravity is caused, and the weight of the balancing weight is controlled to be 1.2% -1.5% of the whole weight of the trolley body to be optimal through tracking observation comparison for a certain time.
The dog in this embodiment is not the only fixed setting, adopts the form of drive screw top, and the flexible position that can adjust the dog in certain limit of drive screw, promptly when the parking spot that the dog on the walking track corresponds needs fine setting, just adjusts the position of dog through drive screw to the accurate control of adaptation parking spot.
