Description

Technical Field

[0001] This utility model relates to the technical field of industrial silicon production equipment, and in particular to a portable silicon cask traction connection mechanism. Background Technology

[0002] Industrial silicon, a core raw material for high-end industries such as photovoltaics and semiconductors, relies on high-temperature electric furnaces to melt silicon raw materials. The resulting molten silicon (typically at 1400-1600℃) is precisely injected into a silicon ladle below through the furnace nozzle. The silicon ladle, as the core container holding the molten silicon, must be fixed in a dedicated silicon ladle cart and then transported via tracks laid on both sides of an arc-shaped emergency ditch around the furnace. A full ladle is pulled to the casting area, while an empty ladle is moved to the area below the furnace nozzle. This process requires at least two silicon ladle carts to work alternately on the same set of tracks. Several guide wheels are sequentially installed along the direction of travel within the emergency ditch. The traction rope of the winch contacts the surface of the guide wheels, and the elliptical traction ring at the free end of the traction rope is connected to the silicon ladle cart to achieve traction and transportation of the silicon ladle cart.

[0003] Currently, the industry generally adopts the traditional "manual trench connection" operation mode. The specific operation process is as follows: When it is necessary to switch silicon wafer carts, workers need to carry tools such as traction rings and pins, bend over or squat down to enter the accident trench with a depth of about 800mm to receive leaked silicon liquid; at the bottom of the silicon wafer cart, the traction lug hole and traction ring hole of the silicon wafer cart need to be manually aligned, the pin is inserted to complete the fixation, and then climb out of the accident trench to start the winch to pull; after the silicon wafer cart is in place, the worker needs to enter the trench again to pull out the pin, remove the traction ring, and then move the traction rope to another silicon wafer cart, repeating the above trench connection steps.

[0004] This traditional model suffers from three major pain points, which have become key bottlenecks restricting the safety and efficiency of industrial silicon production: 1. Workers need to complete more than 300 trench entry operations per day, with different silicon carbide vehicles and different track positions. Each trench entry lasts for 1-2 minutes. Workers need to frequently bend over, squat, and climb the trench walls. The cumulative working time per day exceeds 5 hours. The work is frequent and labor intensity is high. Long-term work can easily lead to occupational diseases such as lumbar muscle strain and knee joint damage. Moreover, workers also face safety risks such as falls and slips when going up and down the trench.

[0005] 2. When workers enter the trench to work, they need to operate with their bare hands below the side of the silicon ladle truck, with their head and torso only 30-50cm away from the bottom of the silicon ladle. If the silicon ladle develops weld cracks or wall erosion due to long-term high temperature (i.e., "blade penetration"), the molten silicon will leak into the accident trench instantly. At this time, the space inside the trench is narrow, and personnel cannot evacuate quickly, which will pose a great safety risk.

[0006] More importantly, there is currently no dedicated connection tool for this scenario in the industry. Most companies only mitigate the risks by increasing workers' protective equipment (such as heat-resistant clothing and non-slip shoes), but this cannot fundamentally solve the core problem of "mandatory ditch entry for work". As a result, the contradiction between safety and efficiency has persisted for a long time. There is an urgent need for a connection mechanism that can break through the existing operating mode and completely eliminate the manual ditch entry operation. Utility Model Content

[0007] The main purpose of this utility model is to provide a portable silicon bag traction connection mechanism that completely eliminates the risk of falls and slips caused by more than 300 ditch entries per day; avoids the major safety hazard of burns from molten silicon splashes from the root; and avoids occupational diseases such as lumbar muscle strain caused by frequent bending and climbing, greatly reducing labor intensity, significantly improving work efficiency, reducing the number of traction system downtimes, and greatly enhancing traction stability.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable silicon package traction connection mechanism, which includes a connecting main board and a hanging ring post. A pin hole is provided on the connecting main board, the hanging ring post is vertically fixed on the front side of the connecting main board, and a reinforcing rib is fixed between the hanging ring post and the connecting main board.

[0009] Furthermore, positioning plates are fixed on the connecting main plates on both sides of the hanging ring column, and the two positioning plates are located on both sides of the reinforcing rib plate.

[0010] Furthermore, a semi-circular groove for a lifting ring is provided at one end of the connecting main board near the hanging ring post; the reinforcing rib is located between the semi-circular groove for the lifting ring and the hanging ring post.

[0011] Furthermore, an "L"-shaped anti-tilt baffle is fixed on the back of the connecting motherboard, and a through hole corresponding to the pin hole is provided on the horizontal section of the anti-tilt baffle.

[0012] Furthermore, an anti-sway limiting groove is provided at one end of the connecting motherboard near the pin hole.

[0013] This utility model has the following beneficial effects: 1. This utility model has a simple structure and is easy to implement. After using the connection mechanism of this utility model, personnel are no longer required to frequently enter the 800mm deep accident trench, completely eliminating the risk of falls and slips caused by more than 300 trench entries per day. At the same time, it is far away from the high-risk area of ​​30-50cm at the bottom of the silicon bag. In the event of a "penetration" leak, personnel have sufficient evacuation space outside the trench, thus avoiding the major safety hazard of burns from molten silicon splashes from the root. At the same time, the operation process is reduced from the traditional 4 steps of "entering the trench - aligning - inserting the pin - exiting the trench" to 3 steps of "hooking - attaching - detaching", avoiding occupational diseases such as lumbar muscle strain caused by frequent bending and climbing, greatly reducing labor intensity and significantly improving work efficiency.

[0014] 2. This utility model uses positioning plates on both sides of the hanging ring column to circumferentially limit the traction ring, preventing it from rotating or shifting. This effectively avoids collisions and jamming between the traction ring and the side wall of the guide wheel in the accident trench, ensuring smooth transmission of the traction rope along the surface of the guide wheel. The anti-sway limiting groove is precisely engaged on the traction column of the silicon-coated vehicle, achieving horizontal limiting and preventing left and right swinging from colliding or jamming with the side wall of the guide wheel set along the direction of travel in the accident trench. This reduces the number of traction system downtimes and significantly enhances traction stability. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-3The principles and features of this utility model are described, making the technical means, creative features, and achieved objectives of this utility model easy to understand, and further elaborating on this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-2 As shown, the technical solution adopted by this utility model is as follows: a portable silicon package traction connection mechanism, which includes a connecting main board 1 and a hanging ring post 2. A pin hole 101 is provided on the connecting main board 1. The hanging ring post 2 is vertically fixed on the front side of the connecting main board 1. A reinforcing rib plate 3 is fixed between the hanging ring post 2 and the connecting main board 1.

[0024] Positioning plates 4 are fixed on the connecting main plates 1 on both sides of the hanging ring column 2, and the two positioning plates 4 are located on both sides of the reinforcing rib plate 3.

[0025] A semi-circular groove 102 for the lifting ring is provided at the end of the main board 1 near the hanging ring post 2; a reinforcing rib 3 is located between the semi-circular groove 102 for the lifting ring and the hanging ring post 2.

[0026] An "L"-shaped anti-tilt baffle 5 is fixed on the back of the main board 1. A through hole 501 corresponding to the pin hole 101 is provided on the horizontal section of the anti-tilt baffle 5.

[0027] An anti-sway limiting groove 103 is provided at the end of the motherboard 1 near the pin hole 101.

[0028] Working principle: such as Figure 3 As shown 1. Fixing the connecting mechanism to the silicon wafer cart 7: Inside the accident ditch 6, the operator precisely inserts the anti-sway limiting groove 103 of the connecting main board 1 near the pin hole 101 into the traction column 8 of the silicon wafer cart 7 to achieve horizontal limiting and prevent left and right swaying, collision or jamming with the side wall of the guide wheel 12 set along the direction of travel in the accident ditch 6; then align the pin hole 101 of the connecting main board 1 with the traction lug hole of the silicon wafer cart 7, while ensuring that the through hole 501 of the horizontal section of the "L"-shaped anti-tilt baffle 5 on the back of the connecting main board 1 is coaxial with the pin hole 101, and insert the pin 10 through the through hole 501, pin hole 101 and traction lug hole to complete the stable connection between the connecting mechanism and the silicon wafer cart 7. The anti-tilt baffle 5 fits the traction lug 9 of the silicon wafer cart 7 through the "L"-shaped structure to prevent the connecting main board 1 from tilting downward under force, causing the traction ring 11 to fall off; this fixing process only needs to be done once, and there is no need to repeat disassembly and assembly afterwards.

[0029] 2. Traction Connection Operation: The operator holds the operating hook outside the accident ditch 6 and hooks the traction ring 11 of the winch, then hangs it on the hanging ring post 2. After that, the traction ring 11 is adjusted so that it fits around the positioning plates 4 on both sides of the hanging ring post 2. At this time, the positioning plates 4 abut against the arc-shaped end of the traction ring 11 from the inside, forming a circumferential limit, which completely prevents the traction ring 11 from rotating around the hanging ring post 2 or shifting radially during the traction process. This avoids the traction ring 11 from colliding or getting stuck with the side wall of the guide wheel 12 set in the direction of travel inside the accident ditch 6, and ensures that the traction rope 13 slides smoothly along the surface of the guide wheel 12. The reinforcing rib plate 3 between the hanging ring post 2 and the connecting main plate 1 forms a triangular support structure to resist the longitudinal tension during the traction process and prevent the hanging ring post 2 from tilting and deforming.

[0030] 3. Traction and disengagement operation: After the silicon wafer trolley 7 reaches the target position, the operator holds the operating hook and inserts the hook head into the semi-circular groove 102 of the lifting ring connected to the main board 1 from below (the groove has sufficient operating space) to hook the bottom of the traction lifting ring 11; pull the operating hook upward to move the traction lifting ring 11 along the hanging ring post 2 away from the limiting range of the positioning plate 4 until it is completely separated from the hanging ring post 2; finally, the traction lifting ring 11 is moved to the corresponding mechanism of the next silicon wafer trolley 7 to be tractioned by the operating hook, completing a single traction cycle.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
