The overall height of a common single crystal furnace device reaches several meters. Therefore, the work of arranging the crystal rope into the pulling device requires relevant technical personnel to work at a height. The design of a traditional single crystal furnace is based on smaller-scale crystal pulling needs. The size, weight and amount of crystal pulling are small. To meet this demand, the pulling equipment of a traditional single crystal furnace adopts a simple assembly structure of a winding wheel, a fixed pulley, a driving device and other parts, so that there are many connection points and connecting parts on the overall structure. When setting the crystal rope, it is necessary to repeatedly disassemble multiple components, which increases the difficulty and pressure of operation for personnel working at heights, affects work efficiency, and repeated disassembly work will destroy the strength and stability of the overall structure, and cannot meet the emerging demand for large-size and heavy crystal pulling.

If the specific posture changes, the directional indication will also change accordingly.

[0027] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0028] The present invention provides a crystal rope pulling device for a single crystal furnace, comprising a chassis 11 , a box body 12 , and a wire winding mechanism and a pulling mechanism arranged in the box body 12 .

[0029] Reference Figure 1 and Figure 2 The chassis 11 is arranged on the top of the single crystal furnace equipment to form an installation platform for the box body 12. A cavity that is vertically connected and integrated is formed in the box body 12, so that the box body 12 becomes a frame for sequentially arranging the wire winding mechanism and the traction mechanism from bottom to top.

[0030] Among them, refer to Figure 3 and Figure 4 The wire winding mechanism includes a wire winding drive shaft 21 and a wire winding wheel 22. The wire winding drive shaft 21 is horizontally inserted into the box body 12, and one of the shaft ends of the wire winding drive shaft 21 is inserted into the outside of the box body 12. A driving motor 13 and a reducer are installed on the chassis 11. The outer shaft end of the wire winding drive shaft 21 is connected to the output end of the reducer, and then the driving motor 13 drives the wire winding drive shaft 21 to rotate.

[0031] The winding wheel 22 is coaxially sleeved outside the winding drive shaft 21, and the winding wheel 22 and the winding drive shaft 21 form a key connection, so that the rotation of the winding drive shaft 21 can synchronously drive the rotation of the winding wheel 22, and the winding wheel 22 can also slide relative to the winding drive shaft 21 along the axial direction of the winding drive shaft 21.

[0032] The outer periphery of the winding wheel 22 is provided with spiral grooves 221, which are arranged in an axial spiral distribution along the winding wheel 22. The crystal rope can be wound in the spiral grooves 221 along the spiral direction. The spiral grooves 221 have a set depth, and the bottom of the spiral grooves 221 is set to an arc shape to ensure that the crystal rope is stably accommodated in the spiral grooves 221.

[0033] The traction mechanism includes a fixed pulley 31, a bracket 32 ​​and a cover plate 33. The fixed pulley 31 is rotatably arranged on the bracket 32, and the bracket 32 ​​is fixedly installed on the cover plate 33. An opening is arranged on the top of the box body 12, and the cover plate 33 is detachably installed on the top of the box body 12, so that the fixed pulley 31 is arranged in the cavity of the box body 12 and is located above the winding wheel 22, and an effective supporting and fixing strength for the entire traction mechanism is formed through the box body 12. The axial direction of the fixed pulley 31 is arranged horizontally. In this embodiment, the axis of the fixed pulley 31 is preferably parallel to the axis of the winding wheel 22.

[0034] A groove 311 for laying a crystal rope is provided on the outer peripheral surface of the fixed pulley 31 .

[0035] One end of the crystal rope is fixed to one side of the winding wheel 22, and the other end is wound along the spiral tooth groove 221 for several turns and then led out upward, and is laid along the outer circumference of the fixed pulley 31. Figure 3As shown, a through hole 111 is vertically penetrated on the chassis 11, and the through hole 111 is connected to the cavity in the box body 12. The crystal rope is laid on the fixed pulley 31 and then pulled downward, and then passed through the through hole 111 and led downward, so that the other end of the crystal rope is set on other equipment of the single crystal furnace, thereby completing the setting of the crystal rope.

[0036] Furthermore, in this embodiment, a window 14 is provided on one side of the four sides of the box body 12, and the window 14 is connected to the cavity in the box body 12 to form an opening. The window 14 is vertically set to a set height, and preferably, the window 14 is opened on one side perpendicular to the axial direction of the wire winding drive shaft 21, so that the window 14 is opposite to the circumferential surface of the wire winding wheel 22 and the circumferential surface of the fixed pulley 31.

[0037] A guide mechanism is provided on the other side of the box body 12. Figure 3 and Figure 6 The guide mechanism includes a guide wheel 41 and a mounting frame 42, wherein the mounting frame 42 is fixedly mounted on the box body 12, and the guide wheel 41 is arranged on the mounting frame 42 to face the cavity, and the guide wheel 41 is arranged at a set radial position on the outer periphery of the winding wheel 22. In this embodiment, the guide wheel 41 is located on the side of the box body 12 relative to the window 14, and the axis of the guide wheel 41 is arranged parallel to the axis of the winding wheel 22, so that the outer peripheral edge of the guide wheel 41 extends into the spiral tooth groove 221, and the side surface of the guide wheel 41 is against the side wall of the spiral tooth groove 221. When the winding drive shaft 21 drives the winding wheel 22 to rotate, the spiral action of the spiral tooth groove 221 relative to the guide wheel 41 will synchronously generate an axial force to make the winding wheel 22 slide along the axial direction of the winding drive shaft 21.

[0038] Therefore, when setting the crystal rope, it is preferred to set the crystal rope at the connecting part between the fixed pulley 31 and the winding wheel 22 to a vertical posture. In the subsequent process of winding or releasing the crystal rope by the winding wheel 22, the crystal rope between the fixed pulley 31 and the winding wheel 22 can be kept in a vertical posture at all times in cooperation with the axial sliding of the winding wheel 22, that is, the vertical center line of the groove 311 of the fixed pulley 31 is downwardly aligned with any one of the multiple spiral tooth grooves 221 axially arranged at the top or side position of the winding wheel 22, thereby maintaining the stability of the crystal rope, preventing the crystal rope from falling off or jumping from the fixed pulley 31 or the winding wheel 22, and preventing the crystal rope from contacting with the sharp edges of the spiral tooth grooves 221 or the sharp edges of the fixed pulley 31 and causing damage.

[0039] Preferably, the guide wheel 41 is rotatably disposed on the mounting frame 42, and the guide wheel 41 can also rotate when the winding wheel 22 rotates, thereby reducing the mutual friction and avoiding jamming.

[0040] For the pulling device in this embodiment, when the staff performs the high-altitude operation of setting the crystal rope, compared with the traditional pulling head, there is no need to disassemble the box body 12 and the internal fixed pulley 31, etc. The window 14 directly opens the winding mechanism and the traction mechanism inside the box body 12, and the staff can directly fix one end of the crystal rope to one side of the winding wheel 22 through the window 14. For details, refer to Figure 5 A slot 222 is provided on the outer periphery of one axial end of the winding wheel 22. The slot 222 is connected to the axial starting point of the spiral tooth groove 221. A fastening bolt is provided in the slot 222. The end of the crystal rope is tightened in the slot 222 by screwing in the fastening bolt to fix it.

[0041] In some embodiments, when setting the crystal rope, the winding wheel 22 is rotated and axially shifted in advance to place the winding wheel 22 in a set position. In the set position, the center line of the groove 311 of the fixed pulley 31 is close to directly above the slot 222. After one end of the crystal rope is fixed to the slot 222, it is directly laid upward on the fixed pulley 31, so that the crystal rope can be wound around the spiral tooth groove 221 by subsequently driving the winding wheel 22 to rotate, thereby effectively simplifying the setting operation of the crystal rope.

[0042] Furthermore, a door panel is provided at the window 14 , one side of the door panel is connected to the box body 12 by a hinge, and the door panel body forms a detachable connection with the box body 12 to realize opening and closing of the window 14 by the door panel. The door panel is made of transparent materials such as glass or plastic, which is convenient for the staff to directly observe the interior of the box body 12 .

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
