Description

Technical Field

[0001] The utility model belongs to the technical field related to heat preservation barrel prompts, and in particular relates to a heat preservation barrel lifting device for a single crystal furnace. Background Art

[0002] The Czochralski method is currently a common method for growing single crystals. Its working principle is to heat and melt the raw materials that make up the crystal in a crucible, connect a seed crystal to the surface of the melt and pull the melt. Under controlled conditions, the atoms or molecules of the seed crystal and the melt are continuously rearranged at the interface, and the single crystal is grown as the crystal gradually solidifies as the temperature drops. However, when the lifting beam is rotated manually, it is easy to accidentally touch the sliding ring and rotate, causing the slider to move inside the slide slot and break away from the restriction of the limit slide slot, resulting in the sliding ring and the fixed body separating and falling off.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 The illustrated single crystal furnace insulation barrel lifting device comprises a fixed body 4 and a sliding ring 7 installed on the upper side of the fixed body 4;

[0024] The outer wall of the upper end of the sliding ring 7 is fixedly connected with a plurality of sliding blocks b10 at equal intervals;

[0025] A plurality of upwardly opening sliding grooves 6 are evenly spaced inside the outer wall of the upper end of the fixed body 4;

[0026] The other ends of the multiple slide grooves 6 are all provided with positioning grooves 5, and the outer wall of the lower end of the sliding ring 7 is equidistantly fixedly connected with multiple sliders a8 to be inserted into the slide grooves 6 to limit the position of the sliding ring 7. When lifting the heat preservation bucket, the heat preservation bucket and the sliding ring 7 are first clamped and fixed, and then the sliding ring 7 is rotated clockwise to make the slider a8 slide from the slide groove 6 into the positioning groove 5. At this time, the force-bearing module on the inner wall of the main chamber is clamped with the sliding ring 7, which can drive the heat preservation bucket to move up. When it is necessary to lift the main chamber alone, the sliding ring 7 is rotated counterclockwise to make the slider a8 slide from the positioning groove 5 into the slide groove 6, and the main chamber can be lifted alone.

[0027] A plurality of arc-shaped caps 12 are equidistantly arranged inside the inner wall of the lower end of the slide groove 6 to limit the position of the slider a8. The outer walls of the lower ends of the plurality of arc-shaped caps 12 are fixedly connected with a reset spring 15 to limit the position of the arc-shaped caps 12. During the operation of the staff, if the sliding ring 7 is accidentally touched to cause the slider a8 to shift in position, the movement of the slider a8 can be limited by the arc-shaped cap 12 to avoid the slider a8 from being displaced.

[0028] like Figure 3 As shown, the lower inner wall of the slide groove 6 is provided with a plurality of upwardly opening mounting grooves 17 to limit the position of the reset spring 15, the lower outer walls of the plurality of arc caps 12 are fixedly connected with a baffle 14, a limiting plate 13 is fixedly connected between the uppermost sides of the inner walls at the left and right ends of the mounting groove 17 to limit the maximum upward movement range of the arc cap 12, and the lower inner wall of the mounting groove 17 is fixedly connected with a sliding sleeve 16.

[0029] During the sliding process of the slider a8, the force exerted by the staff in pushing the slider a8 to move will cause the arc cap 12 to move downward, and cause the reset spring 15 to contract, while causing the slide rod 18 to slide down into the inside of the slide sleeve 16, so that the positioning groove 5 can slide into the inside of the slide groove 6, and the sliding ring 7 can be moved upward. When the slider a8 escapes from the slide groove 6 or slides into the positioning groove 5, the reset spring 15 resets and pushes the arc cap 12 to move upward, so that the baffle 14 at the lower end of the arc cap 12 and the limit plate 13 on the inner wall of the mounting groove 17 fit together, thereby limiting the moving distance of the arc cap 12.

[0030] like Figure 3 As shown, the sliding sleeve 16 is internally slidably connected with a sliding rod 18 to limit the moving direction of the arc cap 12. The center of the baffle 14 is through-through, and the arc cap 12, the return spring 15 and the sliding rod 18 are fixedly connected by welding. The arc cap 12 drives the sliding rod 18 to move downward after being pressed down.

[0031] The stability of the arc cap 12 during its up and down movement is limited by the slide bar 18, and the situation that the arc cap 12 cannot pass through the baffle 14 by mistake during the resetting process of the reset spring 15 is avoided.

[0032] like Figure 1 As shown, grooves 9 are provided on the left and right outer walls of the slider a8 to adapt to the size of the positioning groove 5, and a plurality of front-to-back through-grooves 3 are equidistantly provided inside the front circular outer wall of the fixed body 4, and a lifting beam 1 is clamped inside the plurality of grooves 3, and a bottom lifting plate 2 is fixedly connected between the lower end outer walls of the plurality of lifting beams 1.

[0033] When the slider a8 slides into the positioning groove 5, the grooves 9 opened on the inner walls at the left and right ends of the slider a8 can be stably inserted into the positioning groove 5 to limit the position, thereby preventing the slider a8 from moving upward inside the positioning groove 5. The main chamber can be lifted by the bottom lifting plate 2 and its position can be limited.

[0034] like Figure 1 As shown, a positioning rod 11 is fixedly connected to the upper outer wall of the sliding ring 7 near the right side for the staff to control the movement of the sliding ring 7, and the lateral length of the circular inner wall of the bottom lifting plate 2 is smaller than the lateral length of the sliding ring 7 to support the main chamber.

[0035] The sliding ring 7 is controlled to move left and right by the positioning rod 11. The lateral length of the circular inner wall of the bottom lifting plate 2 is smaller than the lateral length of the sliding ring 7 so as to lift the insulation barrel. The main chamber under the insulation barrel can be better lifted to increase the stability of the main chamber when it is placed.

[0036] The implementation principle of this embodiment is: when lifting the insulation barrel, first, the insulation barrel and the sliding ring 7 are clamped and fixed, and then the sliding ring 7 is rotated clockwise to make the slider a8 slide from the slide groove 6 into the positioning groove 5. At this time, the force-bearing module of the inner wall of the main chamber will be clamped with the sliding ring 7, which can drive the insulation barrel to move upward. When it is necessary to lift the main chamber alone, the sliding ring 7 is rotated counterclockwise to make the slider a8 slide from the positioning groove 5 into the slide groove 6, and the main chamber can be lifted alone. During the operation of the staff, if the sliding ring 7 is accidentally touched to cause the slider a8 to shift in position, the arc cap 12 can be used to limit the movement of the slider a8 to avoid the slider a8 from being displaced.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
