Background

At present, in a solar polycrystalline silicon ingot casting method, a raw material silicon material is generally placed in a crucible and heated, when the temperature in the crucible exceeds the melting point of the silicon material, the silicon material is heated and melted to form silicon melt, and when the temperature of the silicon melt is stable, the silicon ingot is formed by cooling. The crucible has harsh use conditions and high technical performance requirements, and is an irreplaceable key consumption material in the production process of the polysilicon cast ingot. There are two general methods for preparing the crucible, slip casting and injection molding. The slip casting is a crucible production mode of mixing and ball milling raw materials to prepare slip casting slurry, injecting the slurry into an assembled mould, demoulding when a blank reaches a certain strength, drying the blank and sintering.

The assembly of the mold has great influence on the size, the wall thickness and the surface quality of the crucible, and the blank is easy to stick and crack during demolding, so that the operations of mold assembly and demolding need high technology. Because the mould that adopts is porous gypsum, be inconvenient for realizing automatic dismantlement with the mode of snatching, the dismouting of crucible mould adopts the manual work to realize at present more, and especially the dismouting of side mould can only carry out the dismouting operation with the help of the steel pipe hole of embedding in porous gypsum mould and distributing in mould both sides limit. Also, since the porous gypsum mold is not a precision mold, the positions of the dismounting holes on the two sides of the porous gypsum mold on the mold are not uniform, and errors are large, so that the feasibility of the automatic tool operation is further limited.

Moreover, when the die is manually disassembled, two people are generally required to finish the assembly and disassembly simultaneously, the efficiency is low, the maneuvering performance is poor, the labor cost is high, the labor intensity is high, the safety risk exists, the influence of the proficiency and emotion of operators is large, and the crucible damage is difficult to avoid.

The traction belt 141 may be provided with pulleys at corners of the support beam 140 so that the traction belt 141 smoothly slides on the surface of the support beam 140. In addition, the linear bearing 145 is used for matching the linear stroke with the cylindrical shaft, and the bearing ball is in point contact with the bearing sleeve, so that the steel ball rolls with minimum friction resistance, and the linear bearing 145 has small friction, is stable and does not change along with the bearing speed, and can obtain stable linear motion with high sensitivity and stability.

As shown in fig. 2, the brake assembly 143 includes a first fixing frame 1432 and a second fixing frame 1434 provided on the support beam 140, and a pressing block 1436 hinged to the first fixing frame 1432, a through hole 1438 is provided on the pressing block 1436, and the pressing block 1436 is connected to the second fixing frame 1434 through a fifth elastic member 1439.

Specifically, the rope required for hoisting is connected to the through hole 1438, and when the hoisting and the dismounting are performed, the traction belt 141 slides left and right to realize the balance of forces. When the braking assembly 143 is continuously applied with a force, the fifth elastic member 1439 is elastically deformed, and the pressing block 1436 hinged to the first fixing frame 1432 is rotated by the pulling force of the rope, and at this time, the pressing block 1436 presses the traction belt 141 to brake, thereby restricting the left and right sliding of the traction belt 141. When the rope no longer applies a force to the braking assembly 143, the fifth elastic member 1439 returns to its elastic deformation, and at this time, a force is generated in a direction opposite to the pressing block 1436, and the pressing block 1436 no longer brakes the traction belt 141, and returns to the state before lifting. The fifth elastic member 1439 may employ a tension spring.

It should be noted that, the threshold value of the tension of the fifth elastic member 1439 (the maximum tension value reached when the elastic member is not damaged) is greater than the sum of the tension threshold values of the first elastic member 119, the second elastic member 1145, the third elastic member 129 and the fourth elastic member 1245, and is less than the sum of the gravity of the mold dismounting hanger 100 and one side of the mold 105 to be dismounted.

Optionally, as shown in fig. 4 and 6, elastic pads 150 are provided on the first lock lever 1147 and the second lock lever 1247, respectively. The elastic pad 150 is compressed by a certain amount in the process of lifting the pin shaft 107, so that the motion track of the side wall mold is smoother, and the process of detaching the side wall of the mold 105 to be detached is more reliable.

Optionally, as shown in fig. 1, a limiting component 133 is further disposed on the connecting rod 130 correspondingly, and the limiting component 133 is used for limiting the supporting arm 131. Specifically, the limiting component 133 includes a fixing block, on which a fastening bolt is disposed, and a support arm 131 can be clamped between a bolt cap of the bolt and the fixing block, so that the support arm 131 moves within a fixed range.

The embodiment of the invention also discloses a lifting device, which comprises the die dismounting lifting appliance 100. The lifting device comprises the same structure and advantages as the mould dismounting sling 100 in the previous embodiment. The structure and advantageous effects of the mold dismounting hanger 100 have been described in detail in the foregoing embodiments, and are not described here again.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
