[0002] Single crystal furnace is a kind of equipment for melting polycrystalline material such as polycrystalline silicon in inert gas environment with heater, and growing dislocation-free single crystal by using vertical pulling method.In the process of pulling crystal, single crystal silicon rod is produced by rotating and stretching after connecting in turn by pulling head, tungsten wire rope, heavy hammer, graphite chuck and seed crystal.

[0003] Due to the existing single crystal furnace itself, the temperature in the furnace is as high as 1400 DEG C in the process of pulling crystal rod, and tungsten wire rope, heavy hammer, graphite chuck and the like are in high-temperature and stressed environment for a long time.In order to ensure the safety of pulling crystal, the relevant components need to be inspected before each furnace is opened, and the heavy hammer needs to be disassembled for inspection of tungsten wire rope and graphite chuck during the inspection process;At the same time, if tungsten wire rope reaches the service life, heavy hammer will also be disassembled for replacement of tungsten wire rope.Therefore, heavy hammer disassembly has high frequency.

[0004] At present, the disassembly of single crystal furnace heavy hammer relies on manual disassembly, and this operation mode has the following defects:

[0005] 1, the material of heavy hammer is molybdenum, which has the characteristics of slow cooling speed, so the heavy hammer is still in a high temperature state when disassembled, and personnel are prone to scalding.

[0006] 2, the weight of heavy hammer is nearly 30kg, and two people must cooperate to complete the disassembly and installation each time, so the labor intensity of personnel is large, the efficiency is low, and personnel are prone to safety accidents such as bruising and bruising.

[0007] 3, the heavy hammer is in the furnace when working, so the cleanliness is required, so personnel must wear clean gloves when disassembling, and there is a risk of falling after wearing gloves, which causes the heavy hammer with brittle and high hardness to produce invisible cracks, and further causes significant safety hazards to pulling crystal.

[0008] Therefore, in order to prevent safety accidents such as scalding and bruising of personnel during heavy hammer disassembly, and reduce the labor intensity of personnel, an auxiliary tool for heavy hammer disassembly is urgently needed. UTILITY MODEL CONTENTS

[0009] In view of the deficiencies of the prior art, the utility model provides an auxiliary tool for dismounting heavy hammer of single crystal furnace to solve the problems that personnel are prone to safety accidents such as scalding and bruising during the disassembly of existing heavy hammer, and heavy hammer falls to produce invisible cracks.

[0043] The following disclosure provides many different embodiments or examples for implementing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the utility model.

[0044] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0045] Referring to Figures 1 to 3 The utility model provides a kind of auxiliary tool for single crystal furnace weight dismounting, it includes:

[0046] Support 10 has first layer plate 11 and second layer plate 12 arranged in upper and lower;

[0047] Retainer ring 20 is fixedly installed in the middle of first layer plate 11;And

[0048] Bottom support 30 is fixedly installed in the middle of second layer plate 12;

[0049] Wherein, the middle of first layer plate 11 is provided with the through hole concentric with the inner hole of retainer ring 20 to facilitate the putting of weight 50, and the bottom support 30 is coaxially located below the inner hole of retainer ring 20.

[0050] Specifically, support 10 includes bottom frame 13, second layer plate 12 is fixedly arranged on the top of bottom frame 13, and first layer plate 11 is fixedly supported above second layer plate 12 by four legs 14;The height of leg 14 is less than the distance from the weight sleeve (not shown in the figure) to the lower end of the weight. The height of the leg 14 makes the distance between the retainer ring 20 and the bottom support 30 not affect the dismounting of the weight sleeve and the tungsten wire rope after the weight 50 is put into the retainer ring 20 and supported by the bottom support 30. The retainer ring 20 and the bottom support 30 are designed according to the shape of the weight 50 and the actual situation during dismounting and mounting. When dismounting of the weight is needed, the auxiliary tool is moved to below the auxiliary chamber of the single crystal furnace, and after aligning the marked position, the weight is lowered, the weight passes through the inner hole of the retainer ring 20, and when the lower end of the weight contacts the bottom support 30, the weight is lowered by a certain distance to make the tungsten wire rope not be stressed, and only one operator needs to wear gloves to dismount the weight sleeve, and the tungsten wire rope can be taken out to complete the dismounting of the weight. At this time, the weight is placed on the auxiliary tool in a vertical state consistent with its working state, and the operator can move the auxiliary tool to the waiting area or wait for the completion of the subsequent process, and then re-mount, and the re-mounting process is just the opposite of the dismounting process. That is to say, by means of the retainer ring 20 and the bottom support 30 provided on the support 10, the weight is first supported and temporarily stored and isolated, which can avoid the risk of scalding and hidden cracks caused by the weight falling out of the hand, and then only one operator can complete the dismounting of the weight, thereby reducing the labor intensity of the operator, and the weight placed in a vertical state can save the re-mounting time and improve the work efficiency.

[0051] The diameter of the through hole is larger than the diameter of the inner hole of the retainer ring 20. In this way, when the weight passes through the inner hole of the retainer ring 20, the weight can be prevented from being directly contacted with the first layer plate 11 and being contaminated, which is beneficial to ensure the cleanliness of the weight.

[0052] The diameter of the inner hole of the retainer ring 20 is 1-2 cm larger than the maximum outer diameter of the weight. In this way, the retainer ring 20 can effectively protect the weight while allowing the weight to pass through easily, which is beneficial to the dismounting of the weight.

[0053] The middle part of the bottom support 30 is provided with a groove or a hollow hole matched with the lower end of the weight. The groove or the hollow hole can better limit and protect the lower end of the weight, reduce the shaking when the weight is put in, and avoid the weight from being bumped.

[0054] Referring to Figure 2 As shown in the figure, the guard ring 20 is fixedly connected with the middle part of the first layer plate 11 through a bolt; referring to Figure 3 As shown in the figure, the bottom support 30 is also fixedly connected with the middle part of the second layer plate 12 through a bolt.

[0055] In the embodiment, the guard ring 20 and the bottom support 30 are both made of polytetrafluoroethylene material. The polytetrafluoroethylene has the characteristics of high temperature resistance and low hardness, which can effectively avoid the risk of the weight being polluted and damaged by bumping due to the contact with metal.

[0056] The single crystal furnace weight dismounting auxiliary tool described above further comprises a trolley 40, and the support 10 is fixedly connected with the loading table surface of the trolley 40. In this way, through the rolling of the trolley 40 wheels 41, it is more convenient to move (push) the auxiliary tool, and the alignment of the marked position of the weight can be easily completed, further reducing the labor intensity of the operator and improving the work efficiency.

[0057] The support 10 is welded with the loading table surface of the trolley 40. The welded connection is more firm, improving the stability of the support 10 during movement.

[0058] In the embodiment, the trolley 40 is preferably an AGV intelligent trolley. Through the AGV intelligent trolley to automatically transfer the weight, the labor intensity of the operator can be further reduced.

[0059] The above embodiments are only the preferred embodiments of the present application, and are not a limitation on the technical solutions of the present application. Any technical solutions that can be realized on the basis of the above embodiments without creative labor should be considered to fall within the protection scope of the patent of the present application.
