Compact conformation of the present invention, the layout of each mechanism is ingenious, and the convenience that provides of plant maintenance is provided.In the present invention, drag for blanking device body and be placed in track support means, realize it by walking mechanism and walk in track support means, promote and walk by travel switch control, thereby realize the feature of originally dragging for accurate, the quick ejection of blanking device.This drags for blanking device and also possesses following advantage: can under hot environment, normally work; Simple and reliable for structure, easy to maintenance; Drag for steel stroke unrestricted, can arbitrarily adjust as required; Dragging for base ability is 35t, is applicable to square billet, the circle base of various large sections.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is for dragging for blanking device body construction schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
As shown in Figure 1 and Figure 2, the present invention includes and drag for blanking device body 1 and track support means 2, drag for blanking device body 1 and be placed in track support means 2, drag for blanking device body 1 and can in track support means 2, slide.
Dragging for blanking device body 1 is made up of girder 101, end carriage 102, hoisting mechanism 103, lifting guiding mechanism 104, buffering stop block 105 and walking mechanism 106, girder 101 is connected by the mode of welding with end carriage 102, and girder 101, end carriage 102 are the box girder structures that formed by Plate Welding.
Track support means 2 is made up of several track girders 201, heavy rail 202, tooth bar 203, car bumper 204, cable balladeur train and approach switch etc., for providing walking to support to dragging for blanking device body 1, carries and drags for the required various cables of blanking device body 1.Track support means 2 is fixed on foundation of civil work by several track girders 201, and heavy rail 202, tooth bar 203 are arranged on track girder 201, and car stop 204 is arranged on track girder 201 ends.
The present invention drags for the course of work of blanking device: drag for blanking device body 1 in the time dragging for base wait position, C type hook 110 is positioned at highest order.When certain first-class strand arrives after ejection roller way, what ejection control system will be sent this stream automatically drags for base instruction, drags for the walking mechanism 106 of blanking device body 1 and starts working, until arrive the automatic stopping behind hook position that enters of this stream.Subsequently, hoisting mechanism 103 is started working, and drives C type hook 110 to drop to automatic stopping after working position.Then walking mechanism 106 starts automatically, enters at a slow speed hook, arrives and drags for automatic stopping behind base position.Subsequently, hoisting mechanism 103 automatically starts, promotes, and drives C type hook 110 that strand is picked up, and stops after arriving the required highest order of technique.Then walking mechanism 106 starts automatically, and the ejection direction that sets to control system (cold send or heat is sent) is walked fast.For preventing the impact of shock loading, send or be coldly provided with one section of deceleration area before sending position in heat, drag for steel machine walking mechanism 106 and go slowly at deceleration area automatic retarding, until arrive automatic stopping behind cold sending (heat is sent) position.Hoisting mechanism 103 starts, declines subsequently, until strand is put down and is placed in rear automatic stopping on slide rail cold bed.The walking mechanism 106 of then dragging for blanking device starts, moves back at a slow speed hook automatically, arrives and rises automatic stopping behind hook position.Hoisting mechanism 103 starts, rises subsequently, after arrival highest order, stops.Then walking structure 106 starts, and gets back to fast to drag for after base is waited for position to stop, and waits for next the sending of base instruction of dragging for.
The present invention utilizes four groups of pinion and racks to realize lifting/decline function.Tooth bar is connected with lifting beam, is equipped with some groups for dragging for the C type hook of base in lifting beam, and C type hook both can drag for square billet, also can drag for round base.Four groups of guiding mechanisms are set the motion of tooth bar is led, the radial load producing while simultaneously utilizing guiding mechanism to eat up rack-and-pinion transmission.Drag for blanking device body and be placed in track support means, realize it by walking mechanism and walk in track support means.Promote and walk by travel switch control, thereby realizing the feature of originally dragging for accurate, the quick ejection of blanking device.
The present invention is simple and practical, can fast, easily large section circumference base strand be transported to the cold bed region of ejection roller way both sides, effectively improves conticaster ejection speed, thereby improves conticaster production capacity and operating rate; The present invention drags for blanking device can realize whole-process automatic ejection, has alleviated operating personnel's labour intensity, simple to operate easy to learn; Ejection control system has sequence latency function, and automaticity is high; The C type hook that drags for blanking device in the present invention can drag for square billet, the circle base of various sections, simple and practical, the trouble that has reduced to change hook.
