Beneficial effect:
The utility model comprises bracing frame, running gear and stabilizing deyice, and the function of stabilizing deyice is that restriction prefabricated rods can only move up and down along the medullary ray of fiber drawing furnace, and the function of running gear is the operation that drives prefabricated rods.It has not only guaranteed that prefabricated rods moves up and down according to setting speed, and the direction that has guaranteed operation is all the time along the direction of prefabricated rods stabilizing deyice regulation.By being used in conjunction with of above two devices, can effectively improving the dynamic collimation degree of prefabricated rods in drawing process, thereby improve technology stability, the reduction optical fiber production cost of drawing process.
Accompanying drawing explanation
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of the utility model linear bearings.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, the utility model comprises bracing frame 6, running gear and stabilizing deyice, and bracing frame 6 is fixed on steel platform 11, running gear is fixed on bracing frame 6 tops, stabilizing deyice is vertical state, and its one end is connected to running gear below, and the other end is connected with prefabricated rods 2.Stabilizing deyice comprises that the prefabricated rods of vertical setting draws 7 and 2 bearing arrangements that linear bearings 5 forms of bar, and prefabricated rods is drawn bar 7 and met but do not need to meet following technical requirements: ovality≤0.15mm simultaneously; Sinuousness≤0.15mm/m; External diameter fluctuation≤0.15mm/m.Prefabricated rods is drawn bar 7 one end and is connected with running gear, and the other end is connected with quiescent levels and angle adjusting mechanism 4 through linear bearings 5, and prefabricated rods 2 is fixed on quiescent levels and angle adjusting mechanism 4.Running gear comprises fixed pulley 8, wireline 9 and windlass 10, and fixed pulley 8 is fixed on bracing frame 6 tops, and windlass 10 is fixed on steel platform 11, and wireline 9 one end are drawn bar 7 with prefabricated rods and are connected, and the other end is connected with windlass 10 after detouring by fixed pulley 8.
With reference to Fig. 2, prefabricated rods is drawn bar 7 and is closely cooperated with the ball 13 of linear bearings 5, and making prefabricated rods draw bar 7 can only slide at vertical direction, and can not rock in the horizontal direction.The outer ring 12 of linear bearings 5 is arranged on the top of wire drawing pylon 3 by a bearing supporting frame.In drawing process, because prefabricated rods is drawn bar 7 and is limited in all the time vertical direction motion by linear bearings 5, thereby make the also position of center line in fiber drawing furnace always of prefabricated rods.
When use, first prefabricated rods is drawn to bar 7 and rise to extreme higher position, then 2 of prefabricated rods are installed on quiescent levels and angle adjusting mechanism 4, make prefabricated rods 2 and fiber drawing furnace 1 on same vertical medullary ray by adjusting quiescent levels and angle adjustment mechanism 4.After 2 dresses of above prefabricated rods and horizontal adjustment work complete, enter the wire drawing production phase.In drawing process, windlass 10 is broadcasted wireline 9 according to the instruction of principal computer PLC with certain speed, and 2 of prefabricated rods move downward under the effect of self gravitation.Because the support mechanism of prefabricated rods 2 is bracing frame 6 and windlass 10, and the two is all arranged on workshop steel platform 11, so the variation of the weight of prefabricated rods 2 can not cause the variation of wire drawing pylon 3 magnitude of inclination in drawing process.
Flexible owing to connecting the wireline 9 that prefabricated rods draws bar 7, so even there are certain displacement or vibrations at drawing process bracing frame 6, also can not cause that prefabricated rods draws the position skew of bar 7.
After above prefabricated rods frame dress and horizontal adjustment work complete, enter the wire drawing production phase.In drawing process, windlass is broadcasted wireline 9 according to the instruction of principal computer PLC with certain speed, and 2 of prefabricated rods move downward under the effect of self gravitation.Because the support mechanism of prefabricated rods 2 is fixed pulley bracing frame 6 and windlass 10, and the two is all arranged on workshop steel structure platform 11, so the variation of the weight of prefabricated rods can not cause the variation of wire drawing pylon 3 magnitude of inclination in drawing process.By being used in conjunction with of above two devices, can effectively improving the dynamic collimation degree of prefabricated rods in drawing process, thereby improve technology stability, the reduction optical fiber production cost of drawing process.
