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.

[0021] As attached Figure 1-4 A heavy-duty single crystal furnace crystal retrieval vehicle is shown, comprising a base plate 1, a support plate 2 is arranged on the top of the base plate 1, a frame 3 is arranged on one side of the support plate 2, a counterweight box 4 is arranged on the other side of the support plate 2, an adjustment component is arranged between the frame 3 and the base plate 1, and a clamping component is arranged on one side of the frame 3.

[0022] As attached Figure 2 , 3 As shown, the adjustment component includes a rotating plate 5 arranged at the bottom of the frame 3, a rotating groove is opened on the surface of the bottom plate 1, the rotating plate 5 is located inside the rotating groove, a first motor 6 is provided at the bottom of the bottom plate 1, and the output end of the first motor 6 is connected to the rotating plate 5, connecting frames 7 are provided on both sides of the frame 3, a slide groove 8 is opened on the surface of the bottom plate 1, and a plurality of sliders 9 are provided inside the slide groove 8, and support rods 10 are provided on the tops of the plurality of sliders 9, and the tops of the plurality of support rods 10 are fixedly connected to the connecting frame 7, and the tops of the plurality of support rods 10 are fixedly connected to the surface of the frame 3. The first motor 6 is started to drive the rotating plate 5 to rotate inside the rotating groove, and the clamping plate 16 can be driven to move by the frame 3, and the position of the rotating plate 5 can be adjusted according to the position of the single crystal rod.

[0023] As attached Figure 1 ,4 As shown, the clamping assembly includes a moving plate 11 arranged on one side of the frame 3, a plurality of hydraulic rods 12 are provided on one side of the moving plate 11, a fixed plate 13 is provided on one side of the hydraulic rod 12, two electric push rods 14 are provided on both sides of the fixed plate 13, and a moving rod 15 is provided on one side of the two electric push rods 14. A clamping plate 16 is provided on one side of the moving plate 11, and the cross-section of the clamping plate 16 is arranged in an arc shape. The hydraulic rod 12 is started to drive the fixed plate 13 to move to one side, and the fixed plate 13 drives the clamping plate 16 to move. When the clamping plate 16 moves to one side of the single crystal rod, the electric push rod 14 is started to make the clamping plate 16 and the surface of the single crystal rod greatly offset, so that the single crystal rod can be clamped and fixed.

[0024] As attached Figure 2 As shown, a rotating rod 17 is provided inside the frame 3, and two moving blocks 18 are threadedly sleeved on the rotating rod 17. One side of the two moving blocks 18 is fixedly connected to the surface of the moving plate 11. A second motor 19 is provided on the top of the frame 3. The output end of the second motor 19 is coaxially connected to the rotating rod 17. When the second motor 19 is started, the rotating rod 17 is driven to rotate. The moving plate 11 is restricted by the moving plate 11, so that the moving block 18 can drive the moving plate 11 to move along the frame 3, and the position of the clamping plate 16 can be adjusted.

[0025] As attached Figure 1 As shown, a seat plate 20 is provided on the top of the base plate 1, and a control panel 21 is provided on one side of the seat plate 20. The control panel 21 can be used to control the crystal retrieval vehicle to clamp and transport the single crystal rod.

[0026] As attached Figure 2 As shown, a plurality of moving wheels 22 are provided at the bottom of the base plate 1, and the tops of the plurality of moving plates 11 are connected to the surface of the base plate 1 by bolts. By removing the bolts, the moving wheels 22 can be easily separated from the base plate 1, and the moving wheels 22 can be replaced.

[0027] The working principle of the utility model is as follows: when in use, first start the control board 21 to drive the moving wheel 22 to run, and move the bottom plate 1 to one side of the crystal taking frame. Due to the different orientations of different crystal taking frames, the crystal taking angles are also different. By starting the first motor 6, the rotating plate 5 is driven to rotate inside the rotating groove, and the rotating plate 5 drives the frame 3 to rotate. When the frame 3 moves, the support rod 10 outside the rotating plate 5 is driven to move, and the support rod 10 drives the slider 9 to move inside the slide groove 8. The support rod 10 can improve the stability of the frame 3 to prevent the frame 3 from moving. During the process, the frame 3 drives the clamping plate 16 to move to the same position as the crystal rack, and then the hydraulic rod 12 is started to drive the fixed plate 13 to move to one side. When the fixed plate 13 drives the clamping plate 16 to move to the side of the single crystal rod, the electric push rods 14 on both sides of the fixed plate 13 are started at the same time, driving the inner walls of the two clamping plates 16 to contact the surface of the single crystal rod. Since the cross section of the clamping plate 16 is an arc, it can better contact the surface of the single crystal rod, and can reduce the gap between the clamping plate 16 and the single crystal rod. After the single crystal rod is clamped and fixed;

[0028] By starting the second motor 19, the rotating rod 17 is driven to rotate, and the rotating rod 17 drives the moving block 18 to move. The moving plate 11 is used to limit the moving block 18, so that the moving block 18 drives the moving plate 11 to move along the frame surface. When the moving plate 11 moves, the single crystal rod can be removed from the crystal rack, and then the frame 3 is driven to rotate by the first motor 6 to place the single crystal rod on the support plate 2, so that the single crystal rod can be transported conveniently, and the single crystal rods in different orientations can be clamped, and the movement of the entire crystal retrieval vehicle can be avoided;

[0029] Due to the different sizes of single crystal rods, their corresponding weights are also different. When the weight of the single crystal rod is greater than the bearing range of the base plate 1, it is easy to cause the base plate 1 to tip over, which will not only cause damage to the single crystal rod, but also reduce production efficiency. By installing a counterweight box 4 on one side of the support plate 2, the weight on one side of the base plate 1 can be increased, which can balance the base plate 1 and increase the stability of the base plate 1. The shaking of the base plate 1 can be avoided, and the normal transportation of the single crystal rod can be guaranteed. The utility model can be suitable for crystal racks in different orientations by adjusting the angle of the frame 3. The stability of the base plate 1 can be improved by the counterweight box 4.

[0030] Finally: The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
