Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnace equipment, in particular to a device for entering a single crystal furnace and centering a lower heat preservation tube. Background Art

[0002] Due to the large size of the single crystal furnace and the need for operators to work at the upper end of the single crystal furnace, the infrastructure will be built into two floors for the convenience of production. The first floor is a supporting pier and the second floor is a working cover platform. The position of the cover platform is about 360mm from the upper edge of the single crystal furnace and about 900mm from the bottom plate of the single crystal furnace. When the operator uses ordinary stairs to enter the hot field to clean the dust, it is necessary to put the ladder into the hot field and then lean on the cover platform to enter. However, this method has the following disadvantages: ① Ordinary stairs are a straight structure with narrow steps and no handrails when entering downwards. It is difficult for operators to maintain balance and there is a risk of falling; ② Ordinary stairs are supported by the bottom plate of the furnace and lean on the cover platform, which has the risk of sliding and affects work safety; ③ When installing the lower insulation cylinder in the single crystal furnace, the operating space is limited, and it is inconvenient to adjust the lower insulation cylinder relative to the single crystal furnace; ④ When the operator enters the hot field to work through ordinary stairs, it needs to be met by outside personnel. The entire work process is high in work intensity, takes a long time to work, and has low efficiency. Utility Model Content

[0028] The following will be combined with the present utility model Figure 1 to Figure 2 , 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 them. Based on the embodiments of 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.

[0029] like Figure 1 to Figure 2 As shown, a device for entering a single crystal furnace and centering a lower insulation tube includes:

[0030] Stand 1;

[0031] A lifting handle 4, which is arranged on the upper part of the vertical board 1;

[0032] A first-level anti-skid stair plate 2, which is vertically connected to the top of the vertical plate 1, and is used to be placed on the cover plate platform 9, fit with the cover plate platform 9, and provide support;

[0033] A secondary anti-skid ladder board 3, the secondary anti-skid ladder board 3 is vertically connected to the bottom of the vertical board 1;

[0034] The retaining edge 5 is arranged on both sides of the vertical plate 1, and the retaining edge 5 is used for safety protection to prevent the operator from stepping on the air and falling and causing accidents;

[0035] A plurality of support legs 6 are provided, and the support legs 6 are fixedly connected to the bottom of the secondary anti-slip ladder plate 3. Reinforcing ribs 8 are provided on the outer sides of the support legs 6. A plurality of bolt holes are provided on the support legs 6. The support legs 6 are arranged in groups of two, and U-shaped polyurethane pads 7 are provided on the inner sides. The U-shaped polyurethane pads 7 are provided with bolt holes corresponding to the support legs 6. The utility model is fixed to the upper edge of the single crystal furnace 10 by tightening the bolts passing through the bolt holes, which effectively prevents the occurrence of sliding accidents. At the same time, the reinforcing ribs 8 provide strength support for the support legs 6 to prevent the support legs 6 from being deformed by force. The presence of the U-shaped polyurethane pads 7 can avoid direct contact between the support legs 6 and the single crystal furnace 10, thereby reducing the wear on the single crystal furnace 10.

[0036] In a preferred implementation, the vertical plate 1 is configured as an arc structure, which is compatible with the working environment and increases the moving space to the greatest extent.

[0037] In a preferred implementation, the first-level anti-skid stair plate 2 is arranged on the outer side of the vertical plate, and the second-level anti-skid stair plate 3 is arranged on the inner side of the vertical plate 1 .

[0038] In a preferred implementation, the lifting handle 4 is in the shape of an elongated strip, and two lifting handles 4 are provided, and the two lifting handles are arranged in parallel transversely.

[0039] In a preferred implementation, the retaining edge 5 is designed as a right-angled triangle, a long side of a right-angled side of the retaining edge 5 is fixedly connected to the vertical plate 1 , and another short side of the right-angled side of the retaining edge 5 is fixedly connected to the secondary anti-slip ladder plate 3 .

[0040] In such Figure 3 In the embodiment shown, four of the present inventions are evenly distributed between the upper edge of the single crystal furnace 10 and the cover platform 9, the support legs 6 are clamped on the upper edge of the single crystal furnace 10 to fix it, and the first-level anti-slip ladder plate 2 is built on the cover platform 9 to support it. With the help of the present invention, operators can enter the single crystal furnace 10 conveniently and quickly to work. When one person installs the lower insulation cylinder, since the single crystal furnace is too large, the staff needs to move and operate among the four devices to ensure that the lower insulation cylinder 11 is relatively centered with respect to the single crystal furnace 10, providing operating space for the staff.

[0041] The utility model uses support legs 6 to be inserted into the upper edge of the single crystal furnace 10, which is not in direct contact with the single crystal furnace 10. It adopts a "Z"-shaped structure and is cleverly placed between the cover platform 9 and the single crystal furnace 10 to provide a working platform for the staff. The utility model does not interfere with the single crystal furnace 10 and can also maximize the platform area, and provides a reasonable step structure to facilitate operators to enter the single crystal furnace 10, protect personnel safety, and conform to ergonomics.

[0042] The above is only a preferred embodiment of the utility model, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that several improvements and deformations can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
