In figure: 1, casing；2, worm-and-wheel gear；3, driving gear；4, sleeve；5, overcoat；6, driven gear；7, drive sleeve；8, drive sleeve spring；9, adjusting nut；10, sliding sleeve；11, sliding sleeve spring；12, spring baffle ring；13, deformed bar tension rod.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments detailed description of the invention of the present utility model is illustrated.
Such as Fig. 1, this fragment-free track slab deformed bar stretch-draw locking device has casing 1, and this casing 1 is fixed on stretch-draw beam.Being positioned at lower box in casing 1 and be provided with worm-and-wheel gear 2, the worm screw of this worm-and-wheel gear 2 is laterally installed on casing 1 longitudinally through casing 1, the worm-wheel shaft of worm-and-wheel gear 2.Fixedly mounting a driving gear 3 side by side with the worm gear of worm-and-wheel gear 2, such as accompanying drawing embodiment, this driving gear 3 is connected fixing by bolt with the worm gear of worm-and-wheel gear 2.The sleeve 4 parallel with the worm-wheel shaft of worm-and-wheel gear 2 and overcoat 5 it is provided with on the top of casing 1, such as accompanying drawing embodiment, sleeve 4 rotatably coordinates assembling by the axle sleeve being fixedly mounted on casing 1 antetheca with casing 1, the outer diameter face of sleeve 4 is provided with coordinate with this axle sleeve inner side end for limiting the positive stop lug boss that sleeve 4 moves forward, overcoat 5 is bolted and is fixed on the overcoat pilot hole that casing 1 rear wall is offered.Sleeve 4 is positioned at the driven gear 6 that the disposed behind of described positive stop lug boss engages with driving gear 3, the drive sleeve disposed behind 7 of driven gear 6, driven gear 6 and drive sleeve 7 matched in clearance are arranged on sleeve 4, the external diameter of drive sleeve 7 and the endoporus matched in clearance of overcoat 5, drive sleeve spring 8 is placed in the spring caulking groove at drive sleeve 7 rear portion, adjusting nut 9 coordinates with the external screw thread being placed in sleeve 4 rear portion, and its front portion enters in the spring caulking groove of drive sleeve 7, such as accompanying drawing embodiment, adjusting nut 9 can increase locking gear.Being provided with sliding sleeve 10 in overcoat 5, the front end face of this sliding sleeve 10 coordinates with the rear end in contact of sleeve 4, the outer diameter face of this sliding sleeve 10 and the endoporus matched in clearance of overcoat 5.Being provided with sliding sleeve spring 11 after sliding sleeve 10, such as accompanying drawing embodiment, be provided with spring baffle ring 12 after sliding sleeve spring 11, this spring baffle ring 12 is bolted the rear end being fixed on overcoat 5.
Such as accompanying drawing embodiment, the preferred disk spring of drive sleeve spring 8 of this fragment-free track slab deformed bar stretch-draw locking device.
This fragment-free track slab deformed bar stretch-draw locking device is used for non-fragment orbit board forming die, and several these devices are installed and used by precalculated position arrangement, make a relative deformed bar tension rod 13 right through sleeve 4 endoporus of this device.The worm screw of the worm-and-wheel gear 2 of adjacent device is connected by shaft coupling, uses same power drive.Worm-and-wheel gear 2 drives driven gear 6 to rotate by driving gear 3, and rotated by the axial compressive force band moving sleeve 4 of drive sleeve spring 8 applying, when sleeve 4 be rotationally advancing be obstructed time, oppressing sliding sleeve spring 11 by sliding sleeve 10 can make sleeve 4 be moved rearwards by, when the front end plum blossom-jaw of the sleeve 4 rotated and the locking nut position of deformed bar tension rod 13 are to timing, sliding sleeve spring 11 promotes sleeve 4 to move forward, drive locking nut rotation to tighten to put in place simultaneously, after locking nut screwing puts in place, the rotary resistance being subject to due to sleeve 4 is more than the rotation friction that drive sleeve spring 8 applies, sleeve 4 stops operating, driven gear 6 dallies, deformed bar stretch-draw has been locked.
