DETAILED DESCRIPTION

[0021] A novel crucible lifting device comprises a lifting rod 1, on which an upper connecting rod seat 2 and a lower connecting rod seat 3 are arranged, wherein the upper connecting rod seat 2 can move up and down along the lifting rod 1, and the lower connecting rod seat 3 is fixedly arranged on the lifting rod 1;

[0022] The upper connecting rod 4 is hinged at both ends of the upper connecting rod seat 2, and the lower connecting rod 5 is hinged at both ends of the lower connecting rod seat 3. A connecting rod 6 is arranged between the upper connecting rod 4 and the lower connecting rod 5. One end of the connecting rod 6 is hinged on the upper connecting rod 4, and the other end of the connecting rod 6 is fixedly connected to the lower connecting rod 5.

[0023] The lower connecting rod 5 is driven by the upper connecting rod 4 and the connecting rod 6 to rotate so as to abut against the inner wall of the crucible 7 .

[0024] Furthermore, a driving structure for driving the upper connecting rod seat 2 to move up and down is provided on the upper connecting rod seat 2, and a limiting structure for limiting the driving structure is provided on the suspension rod 1.

[0025] Furthermore, the driving structure includes an inner bolt 8 disposed on the suspension rod 1, and an outer bolt 9 threadedly connected to the inner bolt 8, and the lower surface of the outer bolt 9 abuts against the upper surface of the upper connecting rod seat 3;

[0026] The limiting structure includes a limiting sleeve 10 which is located on the upper part of the inner bolt 8 and is sleeved on the outside of the suspension rod 1. The lower surface of the limiting sleeve 10 is in contact with the upper surface of the inner bolt 8 to limit the inner bolt 8 in the longitudinal direction. A limiting hole is arranged on the limiting sleeve 10. The suspension rod 1 is provided with a through hole 11 at a position corresponding to the limiting hole. A fastener is provided to pass through the limiting hole and the through hole 11 to fix the limiting sleeve 10 on the suspension rod 1.

[0027] Furthermore, a rotating handle 12 is provided on the side of the outer bolt 9 to drive the outer bolt 9 to rotate.

[0028] Furthermore, a clamping screw 13 is disposed on the end surface of the lower connecting rod 5 , and the clamping screw 13 is rotatably connected to the lower connecting rod 5 .

[0029] Furthermore, the clamping screw 13 forms a plurality of point contacts with the inner wall of the crucible 7 .

[0030] Furthermore, a cavity is provided on the mounting plate 14 for mounting the clamping screw 13, a hollow fixed elastic sleeve 15 is provided in the cavity, an inflation port is provided on the surface of the elastic sleeve 15, and the elastic sleeve 15 is elastically deformed when inflated and can come into contact with the inner wall of the crucible 7.

[0031] The present invention is further described below to better understand the present invention: the structure of this crucible lifting device is as follows: two connecting rod seats are installed on the suspension rod 1, the lower connecting rod seat 3 is at the bottom of the suspension rod 1, and is welded and fixed to the suspension rod 1, the upper connecting rod seat 2 is at the upper part of the lower connecting rod seat 3, and can slide on the suspension rod 1, the upper and lower connecting rod seats are respectively connected to the upper and lower connecting rods, and when lifting the crucible 7, the crucible lifting device is placed in the crucible 7, and the three clamping screws 13 are respectively attached to the inner wall of the crucible 7, the limiting sleeve hole selects an appropriate position to align with the through hole 11 of the suspension rod 1, the limiting pin is inserted, and then the outer bolt 9 is rotated to press the upper connecting rod seat 2 downward. After the clamping screw 13 is pressed against the inner wall of the crucible 7, the lifting is carried out using the lifting ring screw at the upper end of the suspension rod 1.

[0032] The elastic sleeve 15 provided in the present invention is put into use depending on actual conditions. When the clamping screw 13 can form a close contact with the inner wall of the crucible 7, the elastic sleeve 15 does not need to be put into operation. When the clamping screw 13 cannot form a close contact with the inner wall of the crucible 7 due to various reasons such as assembly and manufacturing accuracy, gas can be filled into the elastic sleeve 15. Since the lateral deformation of the elastic sleeve 15 is restricted, it can only produce elastic deformation in the longitudinal direction, so that it is in close contact with the inner wall of the crucible 7, thereby improving the fastening connection of the crucible 7.
