Description

Technical Field

[0001] The utility model relates to a quartz tube manufacturing auxiliary device, in particular to a quartz tube continuous melting furnace core rod assembly auxiliary device. Background Art

[0002] The interior of the quartz tube melting furnace is equipped with a tungsten alloy core rod set in the vertical direction. The role of the tungsten alloy core rod in the quartz tube melting furnace is mainly as a heating element and a supporting structure. Because tungsten has a high melting point, high thermal conductivity and good high temperature resistance, it can withstand the high temperature environment during the quartz melting process and ensure stable heating and melting inside the quartz tube. In addition, the tungsten alloy core rod can also help maintain the shape of the quartz tube to prevent deformation or cracking due to high temperature. In some quartz tube melting furnaces, the tungsten alloy core rod may also be equipped with a cooling system to effectively control the temperature during the heating process and avoid problems caused by overheating.

[0003] When assembling the quartz tube melting furnace, since the tungsten alloy core rod weighs up to 230kg, it is usually necessary to lift the upper end of the core rod through a lifting device such as a crane, and the lower end of the core rod is supported by 4 to 5 people to keep the core rod balanced, and then install the core rod into the quartz tube melting furnace from the furnace mouth.

[0004] However, the above installation method places high demands on the operators, such as long clamping time (usually more than 30 minutes) and uniform clamping force to maintain balance. There are also certain uncertain risks. For example, uneven clamping force due to fatigue may cause the core rod to shake during assembly, causing the core rod to expand the furnace body and damage the insulation bricks of the continuous melting furnace, ultimately affecting production.

The pusher 230 is configured to be able to move close to the supporting mechanism 220 along a first direction so that the core rod 100 is erected from the inclined position. The first direction is parallel to the vertical plane.

[0035] In this embodiment, see Figure 2 , one end of the core rod 100 is the bottom end of the core rod 100 .

[0036] In one embodiment, see Figure 3 to Figure 4 The supporting mechanism 220 rotates to drive the core rod 100 to flip from a horizontal position to an inclined position.

[0037] In one embodiment, see Figure 4 and Figure 5 , the first direction is the horizontal direction X.

[0038] In one embodiment, the pushing member 230 is configured to be further movable along the first direction away from the supporting mechanism 220 .

[0039] In one embodiment, the supporting mechanism 220 includes a supporting arm 221, a rotatable member 222 and a supporting portion 2222.

[0041] See also Figures 3 to 5 In this embodiment, the hinged portion 2221 in the rotatable component 222 is rotatably connected to the support arm 221 in a vertical plane, so that when the core rod 100 is flipped to the upright position, the rotatable component 222 can adaptively rotate to keep the core rod 100 always in sliding contact with the core rod support wheel 223.

[0042] It should be understood that, in the present embodiment, the number of the supporting portions 2222 is not limited to two, and the number of the supporting portions 2222 can be adjusted to more according to actual needs.

[0046] Specifically, the electric drive transmission mechanism 250 is disposed inside the base 210 on a side close to the supporting mechanism 220 to avoid occupying the rotation space of the supporting mechanism 220 .

The support arm 221 of the supporting mechanism 220 is rotatably connected to the base 210 through a rotating shaft, so that the supporting mechanism 220 is rotatably connected to the base 210 through a rotating shaft.

[0050] In one embodiment, in order to facilitate transportation, the base 210 is a movable base, including a base body and a plurality of universal wheels arranged below the base body. More specifically, from a top view, the base body is rectangular as a whole and has a central axis parallel to the long side of the rectangle. The rotation plane of the rotatable member 222 in the supporting mechanism 220 is a vertical plane passing through the central axis of the base body. A slide groove is formed on the top of the base body, and the pusher 230 is a slider structure and is slidably connected in the slide groove, and the threaded screw 240 is located below the pusher 230.

[0051] In one embodiment, the device further includes a cart handle 280 , which is fixedly connected to the end of the base 210 away from the supporting mechanism 220 .

Specifically, one end of the core rod 100 away from the supporting mechanism 220 abuts against the pusher 230, and the upper end of the core rod 100 leans on the core rod support wheel 223.

[0055] Step 2: Move the device supporting the core rod to be assembled to the bottom of the quartz tube continuous melting furnace.

[0056] Step 3: The support arm 221 of the supporting mechanism 220 is rotated by rotating the hand wheel, and the core rod 100 is turned to an inclined position, such as Figure 4 In this process, the push member 230 is limited to a side of its travel away from the supporting mechanism 220.

[0057] Step 4: The threaded screw 240 is driven to rotate by the electric drive transmission mechanism 250. The threaded screw 240 rotates to drive the nut and the pusher 230 to move horizontally toward the supporting mechanism 220, so that the core rod 100 is flipped from the inclined position to the upright position.

There are many methods and ways to realize the technical scheme. The above is only the preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be realized by existing technology.
