Abstract
The invention discloses a supporting-type optical fiber preform suspension device which comprises a pedestal, a vertical post and connectors, wherein an optical fiber preform is vertically arranged and connected to the corresponding connector. The supporting-type optical fiber preform suspension device is characterized in that the vertical post is provided with a clamping part which is flexibly connected to the vertical post; the clamping part comprises a mounting ring, ribs and a supporting structure; the supporting structure is a cylinder of which the central axis is vertically arranged; and the cylinder is provided with a locating hole into which the lower end of the optical fiber preform is embedded. By adopting the structure, the mounting ring on the clamping part mounted on the pedestal is connected to the vertical post, and the lower end of the optical fiber preform is embedded into the supporting structure connected with the mounting ring through the ribs, the upper end of each optical fiber preform is connected with the corresponding connector, and the lower end of each optical fiber preform is connected with the supporting structure, so that the vertically arranged optical fiber preform can not swing in the optical fiber drawing process.
Description
Technical field
The present invention relates to a kind of top support type preform suspension system, particularly relate to a kind of installation and locate reliable top support type preform suspension system.
Background technology
Preform is the starting material manufacturing quartzy series fibre, specifically, is the prefabricated big stick-means of intimidation for pulling optical fiber, is usually sintered by silica particulate material and forms.As is known in the industry, in the process by prefabricated big stick-means of intimidation and preform drawing optical fiber, need that fixed form is outstanding to be fixed on suspension system to hang by prefabricated big stick-means of intimidation.There is following shortcoming in the mode first adopted at present: 1, owing to employing the eccentric strap with lockhole, thus needs to make the end of preform caudal peduncle form a bulb being able to be limited by lockhole, so cause certain difficulty to the processing of preform; 2, limit in mechanism because preform is hung with eccentric state in preform, that is the longitudinal center of preform do not hang with quartz rod longitudinal center consistent, and because the bulb of preform caudal peduncle end is in unfixed free state, thus unavoidably exist to shake in the process of drawing optical fiber and put situation, even there is ball head and scurry out and accidents caused anxiety from the open slot of logical firmly lockhole.
Summary of the invention
Technical problem to be solved by this invention is available to a kind of top support type preform suspension system, has and installs the reliable feature in location.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of top support type preform suspension system, comprise base, be arranged on the montant on base, be arranged on the some connecting joints on described montant, preform vertically arranges and is connected on corresponding described connecting joint, its innovative point is: described base is provided with the clamping part be movably connected on described montant, described clamping part comprises the mounting ring be arranged on described montant, be arranged on described mounting ring along the radially-arranged some ribs of mounting ring, be arranged on the jacking structure away from described mounting ring one end on described rib, described rib quantity is consistent with described connecting joint quantity, the right cylinder that centered by described jacking structure, axis vertical is arranged, on described right cylinder, right cylinder top is provided with the pilot hole embedded for preform lower end.
Preferably, clutch shaft bearing is provided with between described clamping part and described montant.
Preferably, some described connecting joints are all arranged on shack, and described shack is arranged on described montant away from the montant end of base.
Preferably, the second bearing is provided with between described montant and described shack.
Preferably, the 3rd bearing is provided with between described montant and described base.
Preferably, gusset is provided with between described jacking structure and described rib.
The invention has the advantages that: by adopting said structure, the mounting ring that utilization is arranged on the clamping part on base is connected on montant, the jacking structure be connected with mounting ring by rib is utilized to supply the lower end of preform to embed, every root preform upper end is connected with connecting joint, preform lower end is connected with jacking structure, thus makes the preform vertically arranged in the process of drawing optical fiber, there is not rolling pendulum situation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of top support type preform of the present invention suspension system.
Fig. 2 is the partial view A of Fig. 1.
In figure: 1-base, 2-montant, 3-connecting joint, 41-mounting ring, 42-rib, 43-jacking structure, 44-pilot hole, 45-gusset, 5-clutch shaft bearing, 6-shack, 7-second bearing, 8-the 3rd bearing, 9-preform.
Embodiment
A kind of top support type preform suspension system of the present invention comprises base 1, the montant 2 be arranged on base 1, the some connecting joints 3 be arranged on montant 2, and preform 9 vertically arranges and is connected on corresponding connecting joint 3.Base 1 is provided with the clamping part be movably connected on montant 2, clamping part comprises the mounting ring 41 be arranged on montant 2, to be arranged on mounting ring 41 along the radially-arranged some ribs 42 of mounting ring, be arranged on the jacking structure 43 away from mounting ring one end on rib 42, rib 42 quantity is consistent with connecting joint 3 quantity, the right cylinder that centered by this jacking structure 43, axis vertical is arranged, on right cylinder, right cylinder top is provided with the pilot hole 44 embedded for preform 9 lower end.By adopting said structure, the mounting ring 41 that utilization is arranged on the clamping part on base 1 is connected on montant 2, the jacking structure 43 be connected with mounting ring 41 by rib 42 is utilized to supply the lower end of preform 9 to embed, every root preform 9 upper end is connected with connecting joint 3, preform 9 lower end is connected with jacking structure 43, thus makes the preform vertically arranged in the process of drawing optical fiber, there is not rolling pendulum situation.
In order to make clamping part relatively to rotate by montant 2, between clamping part and montant 2, be provided with clutch shaft bearing 5.In order to make connecting joint 3 can rotate relative to montant 2, some connecting joints 3 are all arranged on shack 6, and shack 6 is arranged on montant 2 away from montant 2 end of base 1, is provided with the second bearing 7 between montant 2 and shack 6.In order to make montant 2 to rotate by respect thereto 1, between montant 2 and base 1, be provided with the 3rd bearing 8.In the stretching process of optical fiber, utilize the feature that relative movement can occur between montant 2, clamping part, connecting joint 3, also can realize preform and hang air-cooled effect, and because driving air motion in rotation process thus aggravation air cooling effect.
