Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of electric screw stretching machine as shown in Fig. 1~2, has pedestal crossbeam 7 and tensioning box body 13, and its feature exists
In:Two push rods 6 are provided between described pedestal crossbeam 7 and tensioning box body 13, carriage 12 is provided between two push rods 6;
Motor 1 and screw rod 5 are provided with tensioning box body 13, the motor 1 drives geared system by belt dressing 2
3 operatings, geared system 3 are set on screw rod 5 by gear nut 4, and the other end of screw rod 5 is provided with tension clamp 10, are slided
Weight beam 11 is arranged with screw rod 5 in device 12, the tension clamp 10 is connected with steel wire 8 by anchoring fixture 9.
Tension clamp 10 includes the drag hook group in Y-shaped being made up of some drag hooks 14, and drag hook group is set in bias two
The top of rack 15, the shape of two eccentric racks 15 is " V "-shaped, and the centre of eccentric rack 15 is provided with steel wire 8.
Fixture 9 is anchored using steel tendon heading anchorage or cone anchorage.
Specific stretching machine is made up of screw rod 5, push rod 6, tension clamp 10, weight beam 11 etc..Opened in use, first using
Draw the clamping steel wire 8 of fixture 10, then start motor 1, by belt dressing 2, geared system 3 make gear nut 4 (it is outer with teeth,
Inside have screw thread) rotate, because gear nut 4 can only rotate, it is impossible to it is mobile, therefore force screw rod 5 for linear motion and stretching wire
8。
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, it should all cover within the scope of the present invention.
