[0033] The opening degree adjusting assembly of the embodiment allows the device of the utility model to realize the reduction and expansion of the included angle between the second clamping arm 2 and the first clamping arm 1 while lifting or lowering the second clamping arm 2 and the first clamping arm 1, and is more convenient to operate.
[0034] Referring to Figure 1 , the first clamping arm 1 and the second clamping arm 2 are hinged in the middle and form a whole "X" shape.
[0035] Referring to Figure 1 , the first connecting rod 5 and the second connecting rod 6 are respectively located above the first clamping arm 1 and the second clamping arm 2.
[0036] Referring to Figures 4 to 5 , when the pulling connecting piece 7 is pulled upwards, the lower end of the first clamping arm 1 and the lower end of the second clamping arm 2 are both inwardly folded, and the first clamping plate assembly 3 and the second clamping plate assembly 4 tightly embrace the circular quartz glass ingot 8 from the side of the circular quartz glass ingot 8.
[0037] Further, referring to Figure 1 , the device further comprises an isolation support 9 for separating the first clamping arm 1, the second clamping arm 2 and the circular quartz glass ingot 8, and the isolation support 9 is hinged at the hinge point of the first clamping arm 1 and the second clamping arm 2.
[0038] In order to avoid that the isolation support damages the top end surface of the circular quartz glass ingot 8, the isolation support of the embodiment is preferably made of a material which does not damage the surface of the glass ingot and has a certain strength, such as polyethylene, polytetrafluoroethylene and the like.

At the opening, the size of the clamping space is larger than the circular quartz glass ingot 8, so that the circular quartz glass ingot 8 can directly enter or exit the clamping space when the device is lowered or raised relative to the circular quartz glass ingot 8. When clamping operation is needed, the chain 10 is removed, and the lifting connector 7 is lifted, so that the first clamping plate assembly 3 and the second clamping plate assembly 4 tightly embrace the circular quartz glass ingot 8 from the side of the circular quartz glass ingot 8.
[0043] Specifically, referring to Figure 2 , the first clamping plate assembly 3 and the second clamping plate assembly 4 have the same structure, which comprises a clamping plate body 31, clamping blocks 32, adjusting bolts 33 and a second buffer layer 34, the clamping blocks 32 are provided in two or more, each clamping block 32 is threadedly connected with the clamping plate body 31 through the adjusting bolt 33; the adjusting bolt 33 is transversely inserted into the clamping plate body 31; and the position where each clamping block 32 contacts the circular quartz glass ingot 8 is fixedly connected with the second buffer layer 34.
[0044] The second buffer layer 34 can be a layer of soft and tough protective rubber, which can increase the friction between the first and second clamping plate assemblies and the circular quartz glass ingot 8, and also can protect the surface of the circular quartz glass ingot 8 during clamping, avoiding the side surface of the quartz ingot from being damaged by the clamping blocks 32.
[0045] The position of the clamping block 32 is corrected through the adjusting bolt 33, so that the first clamping plate assembly 3 and the second clamping plate assembly 4 are both in surface contact with the side surface of the circular quartz glass ingot 8, thereby maximizing the contact area and friction.
[0046] Further, referring to Figure 1 , the device further comprises anti-falling safety hooks 11, the lower part of each clamping plate body 31 is respectively hingedly connected with a corresponding anti-falling safety hook 11, and the bottom of the circular quartz glass ingot 8 is stopped and limited by the anti-falling safety hooks 11.
[0047] During the lifting of the circular quartz glass ingot 8 in the embodiment, if the circular quartz glass ingot 8 slides downward, the anti-falling safety hooks 11 can hook the edge of the circular quartz glass ingot 8 to prevent it from continuing to slide downward, thereby preventing the circular quartz glass ingot 8 from falling and being damaged.
[0048] Further, referring to Figure 3The third buffer layer 12 is arranged at the position where the anti-falling safety hook 11 contacts the circular quartz glass ingot 8. The third buffer layer 12 can be a buffer rubber. The position where the anti-falling safety hook 11 contacts the circular quartz glass ingot 8 is generally the upper surface of the hook head and the side surface close to the circular quartz glass ingot 8.
[0049] Further, referring to Figure 1 and Figure 3 The device further comprises a fixed pin 13 for limiting the rotation of the anti-falling safety hook 11 towards the outside of the circular quartz glass ingot 8.

[0050] In order to ensure that the upper surface of the anti-falling safety hook 11 is always parallel to the lower surface of the circular quartz glass ingot 8, the anti-falling safety hook 11 can be made into an inverted "T" type or a G type hook, but is not limited to the above two forms.
[0051] The use process of the device provided by the utility model when hoisting the circular quartz glass ingot 8 will be described below.
[0052] Generally, the circular quartz glass ingot 8 to be hoisted is placed on the ground. The hoisting and clamping device of the utility model is hung on the crane hook through the lifting connecting piece 7, and the crane hook and the crane are not shown in the figure. The hoisting and clamping device of the utility model is hoisted to the upper space of the circular quartz glass ingot 8 by the crane hook, the position is adjusted and the device is slowly lowered. At a suitable height, the fixed pin 13 is pulled out, so that the anti-falling safety hook 11 can be freely rotated to be opened outward. The suitable height is selected according to whether the anti-falling safety hook 11 will bump the circular quartz glass ingot 8. The device continues to be lowered until the isolation support 9 abuts against the top of the circular quartz glass ingot 8, as shown in Figure 4 The hanging chain 10 is opened, for example, the lower end of the hanging chain 10 is released.

The adjusting bolt 33 is adjusted according to the surface arc condition of the circular quartz glass ingot 8, so that the surface of each clamping block 32 is tightly fitted with the side surface of the circular quartz glass ingot 8.
[0053] The crane is pulled upward, and under the action of the lever principle, the lower end of the first clamping arm 1 and the lower end of the second clamping arm 2 are both inwardly retracted, and the first clamping plate assembly 3 and the second clamping plate assembly 4 tightly hold the circular quartz glass ingot 8 inwardly, and the circular quartz glass ingot 8 is hoisted together. As shown in Figure 5As shown, the anti-falling safety hook 11 is affected by gravity and naturally hangs down and is inserted into the fixed pin 13. The anti-falling safety hook 11 and the corresponding clamping plate body 31 are fixed by the fixed pin 13, so that the upper surface of the hook head of the anti-falling safety hook 11 always remains parallel to the bottom plane of the circular quartz glass ingot 8. In some critical situations, when the quartz glass ingot 8 slides downward and the ground of the quartz glass ingot 8 contacts the upper surface of the hook head of the anti-falling safety hook 11, the anti-falling safety hook 11 can prevent the quartz glass ingot 8 from continuing to slide downward, thereby preventing the circular quartz glass ingot 8 from sliding and causing safety and quality accidents.
[0054] After the circular quartz glass ingot 8 is transferred to above the target platform by the travelling crane, the travelling crane is slowly lowered to place the circular quartz glass ingot 8 on the platform. The first clamping arm 1 and the second clamping arm 2 are lowered to abut against the circular quartz glass ingot 8 by the isolation support 9, the opening between the lower end of the first clamping arm 1 and the lower end of the second clamping arm 2 is enlarged, and the first clamping plate assembly 3 and the second clamping plate assembly 4 release the circular quartz glass ingot 8.
