Description

Technical Field

[0001] The utility model relates to the production field of industrial silicon, in particular to an automatic traction mechanism. Background Art

[0002] In the production process of industrial silicon, the safe outflow of silicon liquid is of paramount importance. Under normal circumstances, silicon liquid should flow smoothly from the furnace eye to the silicon bag. The movement of the silicon bag is achieved by using a car as a driving device. In order to ensure that the silicon liquid can flow out safely and avoid spilling the silicon liquid all over the ground and causing waste, when a silicon bag is full of silicon liquid, it is necessary to quickly connect another car. This involves the operation of one car pulling another car forward, and the conventional way to connect cars to each other is to rely on people to hang chains. However, during this operation, the silicon liquid flowing out from the top is often accompanied by sparks flying everywhere. It should be noted that the temperature of high-temperature silicon liquid can reach 1600-2000℃. Once it splashes on the human body, it will inevitably cause the operator to be severely burned, and then cause a work-related accident. In view of this, it is urgent and imperative to invent a mechanism that can automatically pull to eliminate the operation of manual hook removal. Utility Model Content

[0005] The rear fixed plate 2 is fixedly mounted with an articulated seat 21, and a hanging upper jaw 23 is rotatably mounted on the upper part of the articulated seat 21 by inserting a second rotating shaft 22. Guide plates 24 are fixedly mounted on both sides of the articulated seat 21, and guide grooves 241 are opened on the sides of the guide plates 24 on both sides, so that the connecting plate 3 can be inserted into the hanging hole 31 of the guide plate 24 forward along the guide groove 241, and the hanging upper jaw 23 is inserted into the hanging hole 31 downward between the guide plates 24 fixedly mounted on both sides, and a chain connecting seat 25 is fixedly mounted on the upper end of the front side of the hanging upper jaw 23;

[0006] A chain rotating seat 4 is fixedly installed on the side end of the rear fixed plate 2, and a chain shaft 41 is rotatably installed on the chain rotating seat 4. A hand wheel 42 is installed at one end of the chain shaft 41, and a chain 43 is wound on the other end of the chain shaft. The chain 43 is connected to the chain connecting seat 25 fixed on the hanging upper jaw 23.

[0007] The front fixing plate 1 is fixedly connected to the connecting seat 11 and is provided with reinforcing ribs on its side; the rear fixing plate 2 is fixed to the hinge seat 21 and is provided with reinforcing ribs on its side.
