Description

Technical Field

[0001] This utility model relates to the field of photovoltaic single crystal thermal field technology, specifically to a clamping and lifting tool for a single crystal furnace insulation cylinder. Background Technology

[0002] As a core material of modern technology, monocrystalline silicon is important in several key areas. First, monocrystalline silicon is the main material for manufacturing semiconductor devices. Second, monocrystalline silicon solar cells dominate the photovoltaic market due to their high conversion efficiency, and are especially suitable for rooftop power stations and large-scale photovoltaic power stations. They are also widely used in automobiles, medical equipment, and consumer electronics. The importance of monocrystalline silicon stems from its irreplaceable physical properties and its supporting role in many high-tech industries.

[0003] When cleaning the furnace bottom hot zone, it is necessary to use tooling to clamp the insulation cylinder. Two people work together to move the insulation cylinder from the furnace to a flatbed cart. After cleaning the insulation cylinder, it is moved back into the furnace. Each furnace holds three insulation cylinders, and the above operation must be repeated. At this time, the hot zone components are still at a high temperature of about 300°C, which may cause burns and is time-consuming and labor-intensive. Secondly, the insulation cylinder is wrapped with insulation felt, which has low hardness and is easily damaged by slight stress. The clamping tool used is hemp rope, which has a small contact area with the insulation felt. After the insulation cylinder is clamped with hemp rope, the workers lift the insulation cylinder, and the insulation felt is subjected to uneven force, which can easily cause the insulation felt to shift, be cut, or deform. This will not meet the furnace loading standards, requiring rework and increasing the workload. At the same time, the crystal pulling power will also be significantly affected, such as increased power, increased power consumption, and difficulty in finding the temperature. Ultimately, this will easily lead to low output and poor quality. Furthermore, when lifting or moving heavy, tall integrated insulation cylinders, double-layer insulation cylinders, or cleaning the hot zone of a triple-heater system, the heaters and support rods are installed higher than the insulation cylinders. The insulation cylinders must be lifted to a certain height before removal. If the lifting height is insufficient, moving the insulation cylinder, or if it falls abnormally during movement, can easily cause injury to personnel and damage to hot zone components, such as broken heaters or damaged insulation cylinders. In summary, using hemp rope as a clamping tool for insulation cylinders presents risks including high-temperature burns, time-consuming and labor-intensive processes, low safety, large workload, and damage to hot zone components.

[0004] Therefore, it is necessary to invent a clamping and lifting fixture for the insulation cylinder of a single crystal furnace to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a clamping and lifting fixture for a single crystal furnace insulation cylinder. This solves the problems associated with using hemp rope as a clamping fixture for insulation cylinders in actual use, such as high-temperature burns, time-consuming and labor-intensive processes, low safety, large workload, and damage to hot components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping and lifting fixture for a single crystal furnace insulation cylinder includes a support ring. Multiple anti-slip plates are detachably installed on the inner side of the support ring. A tightening bolt for adjusting the clamping range is provided on one side of the support ring. A movable buckle assembly for locking the support ring is provided on the other side of the support ring. Multiple handrails are fixedly installed on the outer side of the support ring.

[0008] In a preferred embodiment of this utility model, the support ring includes a first retaining ring and a second retaining ring. The movable buckle assembly includes a bushing, a guide rod, a locking nut, a limiting step, and an adjusting part. The bushing is fixedly installed at one end of the first retaining ring, and the guide rod is slidably connected to the bushing. The limiting step is fixedly installed at one end of the second retaining ring, and the other end of the guide rod extends to the side where the limiting step is located. The end of the guide rod is provided with an external thread, and the locking nut is threadedly connected to the external thread. The adjusting part is used to control the sliding of the guide rod.

[0009] As a preferred embodiment of this utility model, the adjustment part includes a mounting base, a hinge block 1, a handle, and a synchronous connecting block. The mounting base is fixedly installed on the side where the retaining ring 1 is located. One end of the hinge block 1 is hinged to the mounting base, and the other end of the hinge block 1 is fixedly connected to the handle. The synchronous connecting block is located on both sides of the hinge block 1, and its two ends are respectively hinged to the light rod and the hinge block 1.

[0010] As a preferred embodiment of this utility model, the anti-slip plate is provided with a plurality of easily replaceable fixing bolts at one end facing the inner side of the support ring, and the fixing bolts extend to the outer side of the support ring.

[0011] As a preferred embodiment of this utility model, the handrail is bent, and multiple reinforcing ribs are provided at the bend of the handrail and at the connection with the support ring.

[0012] In a preferred embodiment of this utility model, multiple loosening bolts are provided, and they simultaneously form a sliding connection with both retaining ring one and retaining ring two. The ends of the loosening bolts are locked by nuts.

[0013] As a preferred embodiment of this utility model, one end face of the second retaining ring is provided with a through groove for disassembling the optical rod.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] In this invention, the inner diameter of the support ring can be adjusted by rotating the tightening bolt. After the inner diameter is adjusted, the traditional buckle structure may not be able to guarantee the locking effect. However, by setting up the movable buckle assembly, by adjusting the position of the locking nut and rotating the hinge block one by the handle, the smooth rod can be controlled to slide to one side, so that the first and second buckle rings are locked. This ensures that when facing insulated buckets of different sizes, the device can lock them, guaranteeing the clamping effect and facilitating subsequent lifting with the handle, thus avoiding damage to the insulated bucket.

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] This utility model provides, for example Figure 1-4The fixture shown is a clamping and lifting tool for a single crystal furnace insulation cylinder. It includes a support ring 4, with multiple anti-slip plates 2 detachably mounted on the inner side of the support ring 4. A tightening bolt 3 for adjusting the clamping range is provided on one side of the support ring 4, and a movable buckle assembly 1 for locking the support ring 4 is provided on the other side. Multiple handrails 6 are fixedly mounted on the outer side of the support ring 4. The anti-slip plates 2 are made of high-temperature resistant material at their contact points with the insulation cylinder, and the contact surface with the insulation cylinder has anti-slip textures to increase friction and prevent the insulation cylinder from falling off or bumping into other hot-field components during lifting and movement. The fixture has a large, rough, and uneven contact area with the insulation cylinder felt to prevent the insulation felt from being cut, shifted, or missing, which could lead to failure to meet furnace loading standards and affect normal crystal pulling.

[0023] The support ring 4 includes a first retaining ring 401 and a second retaining ring 402. The movable buckle assembly 1 includes a bushing 109, a smooth rod 105, a locking nut 106, a limiting step 108, and an adjusting part. The bushing 109 is fixedly installed at one end of the first retaining ring 401. The smooth rod 105 and the bushing 109 are slidably connected. The limiting step 108 is fixedly installed at one end of the second retaining ring 402. The other end of the smooth rod 105 extends to the side where the limiting step 108 is located. The end of the smooth rod 105 is provided with an external thread 107. The locking nut 106 and the external thread 107 are threadedly connected. The adjusting part is used to control the sliding of the smooth rod 105. By providing the external thread 107 on the smooth rod 105 and by setting the tightening bolt 3, the locking effect of the movable buckle assembly 1 can be ensured after adjusting the gap between the first retaining ring 401 and the second retaining ring 402, thus preventing the insulation bucket from falling off. The limiting step 108 is designed to prevent the locking nut 106 from loosening or separating from the retaining ring 402, thus preventing the insulation bucket from falling.

[0024] The adjustment unit includes a mounting base 101, a hinge block 102, a handle 103, and a synchronous connecting block 104. The mounting base 101 is fixedly mounted on the side where the retaining ring 401 is located. One end of the hinge block 102 is hinged to the mounting base 101, and the other end of the hinge block 102 is fixedly connected to the handle 103. The synchronous connecting block 104 is located on both sides of the hinge block 102, and its two ends are hinged to the guide rod 105 and the hinge block 102, respectively. By setting the hinge block 102 and the synchronous connecting block 104, the rotation of the handle 103 can be converted into a driving force for the guide rod 105 to slide towards the side where the mounting base 101 is located, thereby achieving the purpose of locking.

[0025] The anti-slip plate 2 has multiple easily replaceable fixing bolts on one end facing the inner side of the support ring 4, and these fixing bolts extend to the outer side of the support ring 4. When the anti-slip plate 2 is damaged and needs to be replaced, the new part can be replaced by loosening or tightening the fixing bolts, reducing the difficulty and cost of product maintenance.

[0026] The handrail 6 is bent, and multiple reinforcing ribs 5 are provided at the bend and the connection with the support ring 4. The multiple handrails 6 are designed using the lever principle to save effort. After clamping the insulation cylinder, the insulation cylinder can be moved away in one go with little effort, improving work efficiency and avoiding rework and additional work.

[0027] Multiple tightening bolts 3 are provided, and they simultaneously form a sliding connection with retaining ring 1 401 and retaining ring 2 402. The ends of the tightening bolts 3 are locked with nuts. By rotating the tightening bolts 3, the size of the inner diameter of the support ring 4 can be controlled to adapt to the contours of different sized insulation barrels and meet the needs of clamping insulation barrels of different sizes.

[0028] One end face of the retaining ring 402 is provided with a through groove for disassembling the light supply rod 105. When it is necessary to disassemble the support ring 4, the through groove facilitates the separation of the light supply rod 105 from the retaining ring 402.

[0029] This invention allows for adjustment of the inner diameter of the support ring 4 by rotating the loosening bolt 3. After the inner diameter is adjusted, the traditional buckle structure may not be able to guarantee the locking effect. However, by setting up the movable buckle assembly 1, adjusting the position of the locking nut 106, and rotating the hinge block 102 via the handle 103, the smooth rod 105 can be controlled to slide to one side, so that the first buckle 401 and the second buckle 402 are in a locked state. This ensures that when facing insulated buckets of different sizes, the device can lock them, guaranteeing the clamping effect and facilitating subsequent lifting using the handle 6, thus avoiding damage to the insulated bucket.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
