[0019] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "longitudinal", "lateral", "horizontal", "inside", "outside", "front", "back", "top", "bottom", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "open", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0022] Example 1

[0023] Since the guide tube itself is at a high temperature for a certain period of time after the single crystal furnace is shut down, operators are prone to burns when lifting the guide tube, which makes operation difficult. If the grip is not firm, the guide tube may break, which poses a high safety risk and low operating efficiency. When the size and weight of the single crystal furnace are large, it will be more difficult for operators to disassemble and install the guide tube by lifting it with multiple people.

[0024] Therefore, in the prior art, some auxiliary devices for disassembling and assembling the guide tube are also adopted. The guide tube is loaded through the auxiliary device, so that the staff can disassemble and assemble the guide tube without directly touching the guide tube with their hands. However, most of the auxiliary devices are not practical. The cylinder-carrying member 4 in the auxiliary device generally fixes the guide tubes of the same size, so that it is convenient for the staff to operate the auxiliary device to disassemble and assemble the guide tube, resulting in that the cylinder-carrying member 4 in the auxiliary device cannot fix the guide tube well, so that the guide tube will shake during the disassembly and assembly process, which is easy to cause accidents.

[0025] Therefore, in order to solve the above problems, the present invention provides an auxiliary device for disassembling and assembling the guide tube of a single crystal furnace. Fixing mechanisms are arranged on both sides of the tube carrier 4. Guide tubes of different sizes are fixed by movable fixing mechanisms, which facilitates the disassembly and assembly work of the staff.

[0026] Specifically, Figure 1 , Figure 2 As shown, an auxiliary device for disassembling and assembling a guide tube of a single crystal furnace comprises a trolley 1, on which a lifting mechanism 3 is provided, on which a first support plate 2 is provided, on which a cylinder carrier 4 for carrying the guide tube is provided, through holes are symmetrically provided on both sides of the cylinder carrier 4, and a fixing mechanism is connected in the through hole, and the fixing mechanism is slidably connected with the first support plate 2 below, so that the fixing mechanism moves toward the through hole to fix the guide tube. The purpose is to provide movable fixing mechanisms on both sides of the cylinder carrier 4, and the fixing mechanisms can be adjusted to fix guide tubes of different sizes, thereby increasing the fixing effect of the auxiliary device on the guide tube, and ensuring that the guide tube will not shake during the disassembly and assembly process, thereby ensuring the safety of the staff and the guide tube will not be damaged.

The purpose is to support the fixing portion 5 in the through hole of the cylinder-carrying member 4 through the supporting portion 6, so that the fixing portion 5 moves horizontally in the through hole while the supporting portion 6 slides on the first support plate 2, so that the fixing portion 5 can move toward the center of the cylinder-carrying member 4, and the fixing portions 5 on both sides can clamp and fix the guide tube located at the center of the cylinder-carrying member 4. Specifically, the fixing plate can be a semicircular ring plate, and the side surface of the semicircular ring plate facing the center of the cylinder-carrying member 4 is an arc surface, which can be in contact with the surface of the guide tube located in the cylinder-carrying member 4, and the semicircular ring plates on both sides can completely clamp and fix the guide tube to prevent the guide tube from shaking.

[0028] Preferably, a groove is provided in the first support plate 2, a reverse threaded rod 21 is horizontally arranged in the groove, a slider 22 sleeved on the reverse threaded rod 21 is provided below the support portion 6, and the sliders 22 below the two support portions 6 are symmetrically arranged on the reverse threaded rod 21. The purpose is to allow the support portions 6 on both sides to simultaneously move closer to or farther from the center of the cylinder carrier 4 under the control of the reverse threaded rod 21, so as to facilitate the operator to fix the guide cylinder.

[0029] Preferably, a base 8 is provided at the center of the first support plate 2, and a second support plate 7 is provided on the base 8, and the second support plate 7 is used to place the cartridge member 4. The purpose is to support and fix the cartridge member 4 through the second support portion 6 to prevent the cartridge member 4 from shaking on the cart 1.

[0030] Preferably, a guide rod 71 is horizontally arranged in the second support plate 7, and the upper part of the support part 6 is sleeved on the guide rod 71, and the guide rod 71 is used to guide the movement of the support part 6 on the first support plate 2.

The guide rod 71 is a smooth sliding rod. When the support part 6 approaches or moves away from the center of the carrier tube member 4 under the rotation drive of the reverse threaded rod 21, the smooth sliding rod guides the support part 6, ensuring that the support part 6 does not shake in the horizontal direction and moves smoothly toward or away from the center of the carrier tube member 4.

[0031] Preferably, a handle 9 is provided on one side of the first support plate 2, and the handle 9 passes through the first support plate 2 and is connected to one end of the reverse threaded rod 21. The purpose is that the reverse threaded rod 21 can be driven to rotate by the handle 9, and the staff can rotate the handle 9 to control the fixing part 5 to move closer to or away from the center of the cylinder carrier 4, so that the staff can fix the guide cylinder.

[0032] Preferably, one end of the fixing portion 5 faces the center of the cylinder member 4, and an anti-skid layer is provided on the end surface facing the cylinder member 4. The anti-skid layer may be a high temperature resistant anti-skid pad, so that after the fixing portion 5 contacts the guide tube, it is not easily affected by the high temperature of the guide tube, and the stability between the fixing portion 5 and the guide tube can be ensured.
