Description

Technical Field

[0001] The utility model belongs to the technical field of anti-sway equipment for optical fiber manufacturing drawing towers, and specifically relates to an anti-sway device for drawing towers. Background Art

[0002] In the prior art, the fiber drawing equipment drawing tower is divided into two types: low-speed drawing tower and high-speed drawing tower, and the production line height is basically between 28 meters and 38 meters. Due to the total height of the tower, process cooling system, curing system and other factors. Generally, the tower below 28 meters is basically a low-speed drawing tower, and its production speed is basically between 1000m / min and 1800m / min. The towers greater than 28 meters to 38 meters are all high-speed drawing towers, and their production line speeds are basically between 1800m / min and 2600m / min. In domestic optical fiber production, conventional enterprises mainly use Φ120mmΦ150mm mother rods for drawing in batches, and some local enterprises also use Φ180mm and Φ200mm mother rods for drawing in batches. The mainstream drawing speed has developed to about 2600m / min at this stage, and is developing towards higher drawing speeds. The development of large rod continuous drawing and high-speed drawing technology has greatly improved the efficiency and production capacity of optical fiber drawing and reduced the cost of optical fiber manufacturing. With the demand for high-speed production, low-speed drawing towers will gradually be replaced by high-speed drawing towers.

[0003] Both low-speed and high-speed drawing towers have the same defect of shaking and swaying of the tower body. Because the overall structure of the drawing tower adopts a tower body laminated hard connection fixed design, the higher the tower body, the worse the stability of the tower body. In particular, the shaking and swaying of the drawing tower with one tower and two lines is particularly obvious during production operations. This phenomenon will lead to a significant increase in the fiber break rate in optical fiber production. Each time the fiber is broken, it takes about 2 hours to cool down, keep warm, and heat up from the fiber break to the re-drawing interval. During this period, the operator needs to re-clean the mold, clean the UV lamp joint, quartz tube, clean the optical fiber channel, and other complete drawing process work, which increases the labor intensity of the operator. In addition, each time the fiber is broken and the re-drawing process, about 10 to 15 km of optical fiber will be adjusted, which will increase the normal consumption of optical fiber coating resin materials and process gases; at the same time, it also reduces the comprehensive utilization rate of preform rods.

[0004] The existing drawing towers are designed to prevent swaying and shaking by connecting the tower bodies in series with hard-connected rods or by hard-connecting the single tower body to the floor mounting bracket. Some manufacturers even use a multi-floor fixed connection method, which not only takes up floor space but also increases a lot of auxiliary costs. At the same time, it cannot eliminate the resonance phenomenon between the floor and the drawing tower body when people walk on the floor. The higher the floor, the higher the amplitude and frequency of the resonance, and the greater the risk of fiber breakage.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0044] like Figure 1 to Figure 2 As shown, the utility model provides an anti-sway device for a wire drawing tower, and the anti-sway device for a wire drawing tower includes:

[0045] The tower body fixing seat is connected with the drawing tower;

[0046] A floor fixing seat, connected to the floor;

[0047] A first gap adjustment mechanism is arranged on the floor fixing seat, and the first gap adjustment mechanism elastically abuts against the tower body fixing seat along a first direction;

[0048] A second gap adjustment mechanism is arranged on the floor fixing seat, and the second gap adjustment mechanism elastically abuts against the tower body fixing seat along a second direction;

[0050] Specifically, the tower body fixing seat is connected to the drawing tower through fixing screws 11, and the floor fixing seat is connected to the floor through chemical expansion screws 10.

[0051] One end of the first gap adjustment mechanism is mounted on the floor fixing seat, and the other end of the first gap adjustment mechanism is elastically abutted against the tower body fixing seat along the first direction.

[0058] Optionally, the gap between the tower body fixing seat and the floor fixing seat should be guaranteed to be 5mm to 8mm, which can effectively block the vibration source generated by the front and rear of the drawing tower from being directly transmitted to the floor fixing seat.

[0059] In some optional embodiments, such as Figure 1 to Figure 2 As shown, the utility model provides an anti-sway device for a drawing tower, and the first gap adjustment mechanism of the anti-sway device for a drawing tower includes:

[0065] Specifically, the first plug 5 is a spherical universal buffer combination pad, or a buffer foot; the second plug 6 is a spherical universal buffer combination pad, or a buffer foot.

[0068] The top surface of the second plug 6 is provided with an anti-skid rubber layer and a silicone sheet layer from the inside to the outside.

[0069] The top surface of the first plug 5 and the top surface of the second plug 6 are formed by gluing together anti-skid rubber and silicone sheets, and have a good buffering effect.

[0070] Furthermore, the tower body fixing seat includes a connecting plate 1 and a vertical plate 2, the connecting plate 1 and the vertical plate 2 are connected at a ninety-degree angle, and the connecting plate 1 is connected to the drawing tower.

[0073] Furthermore, the second gap adjustment mechanism is connected to the second vertical plate 8 , and the second pin 6 is elastically abutted against the vertical plate 2 .

[0074] Specifically: This anti-sway device for a drawing tower needs to be installed one on each diagonal of the left and right sides of a drawing tower body. The specific installation location is the drawing furnace tower floor, and is installed on the columns of the two tower feet on the left and right diagonals of the drawing furnace tower frame and the floor floor.

[0075] The tower body fixing seat comprises a connecting plate 1 and a vertical plate 2. The connecting plate 1 and the vertical plate 2 are connected at a 90-degree angle, and the connecting plate 1 is connected to the drawing tower.

[0076] Use a pen to draw a positioning line on the column of the drawing tower at a distance of 160mm from the floor, mark the four positioning dimensions of the mounting holes of the connecting plate 1 on the positioning line of the column of the drawing tower, and perform drilling and tapping.

[0077] Use 4 fixing screws 11 to fix the tower body fixing seat on the column of the drawing tower through the mounting holes of the connecting plate 1. During installation, the tower body fixing seat must be parallel to the ground and perpendicular to the column. The purpose of fixing the tower body fixing seat is to prevent the drawing tower from shaking left and right and swaying the action base.

[0078] The floor fixing seat comprises a panel 9, a first vertical plate 7 and a second vertical plate 8. The first vertical plate 7 is vertically arranged on the panel 9, the second vertical plate 8 is vertically arranged on the panel 9, and the panel 9 is connected to the floor.

[0080] The three screw holes of the panel 9 of the floor fixing seat are used as the standard. Mark the fixing position on the floor and drill holes. Use three chemical expansion screws 10 to fix the floor fixing seat through the three screw holes of the panel 9. The purpose of fixing the floor fixing seat is to prevent the drawing tower from shaking back and forth and swaying as a benchmark.

[0081] The gap between the tower body fixing seat and the floor fixing seat must be guaranteed to be 5mm to 8mm. This can effectively block the vibration source generated by the front and rear of the drawing tower from being directly transmitted to the floor fixing seat.

[0082] The first gap adjustment mechanism is connected to the first vertical plate 7, and the first distance adjustment component 3 of the first gap adjustment mechanism is connected to the first vertical plate 7 through a double nut, which is adjusted according to the national standard double nut, and the adjustment distance is 50mm to 250mm. The first plug 5 is elastically abutted against the connecting plate 1.

The anti-sway device for a wire drawing tower utilizes the elasticity and vibration absorption properties of a first gap adjustment mechanism and a second gap adjustment mechanism in two directions to convert the energy of vibration and impact into heat energy and elastic deformation energy, effectively reducing the transmission of vibration and noise, thereby protecting the stability and safety of the wire drawing tower.
