[0002] In the metallurgical casting industry, the use of steel casting cars and ladle transfer cars is becoming increasingly popular, no longer limited to traditional gantry hook casting. The ladle used in steel casting cars and transfer cars is equipped with a special detachable base to facilitate safe carrying of the ladle during operation.

[0003] The on-site casting process requires that the ladle filled with high-temperature molten iron must be fixed on its base and transported to the steel casting vehicle by a transfer vehicle for casting operations. After the casting is completed, there is no high-temperature molten iron in the ladle, and it is then transported to the ladle storage location by a transfer vehicle. After the ladle cools down, it is separated from the base.

[0004] The casting process involves securing the ladle to its base at high temperatures and separating it at room temperatures. The existing method for securing the ladle is to manually insert a pin, which creates a safety hazard when the operator is close to the hot ladle. The existing method for separating the ladle from the base is to manually remove the pin. Therefore, when securing or separating the ladle from the base, the operator must insert or remove the pin once per cycle, meaning they must perform two manual operations.

[0005] Based on the above situation, it is necessary to optimize the manual operation process in high temperature environment to reduce safety hazards.

[0006] Therefore, those skilled in the art need to improve the connection structure between the ladle and the base so that it can meet the above requirements. Utility Model Content

[0031] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0032] like Figures 1-6 As shown, a ladle fixing device in a metallurgical casting process includes a ladle fixing seat 1.1, a guide pin 1.2, a guide pin spring lock shaft assembly and a lock shaft unlocking assembly.

[0033] Specifically during installation, the ladle fixing device 1 in the metallurgical casting process is installed on the ladle seat 3, and multiple devices can be arranged around the ladle 2. The bottom end of the ladle 2 needs to be configured with corresponding perforations matching the lock hole and the lock tongue, so that the lock tongue can pass through the ladle 2 into the lock hole to achieve locking.

[0034] The guide pin 1.2 is cone-shaped and fixed on the ladle fixing seat 1.1, and is used to match the positioning hole at the bottom end of the ladle 2 to achieve a guiding effect. A locking hole 1.2.1 is provided on the side of the guide pin 1.2.

[0035] The guide pin spring lock shaft assembly includes a lock tongue 1.5, a spring 1.4, a lock shaft 1.6 and a guide pin clamping plate 1.3. Specifically, a fixed plate 1.1.1 is provided on the ladle fixing seat 1.1, and a square hole is opened on the fixed plate 1.1.1. The guide rod sleeve 1.7 is fixed to the fixed plate 1.1.1 at the square hole by bolts. The inner end of the lock shaft 1.6 is threadedly connected to the guide pin clamping plate 1.3 through an elastic gasket, and the outer end is provided through the guide rod sleeve 1.7. The spring 1.4 is sleeved on the lock shaft 1.6, and the two ends of the spring 1.4 are respectively abutted on the guide pin clamping plate 1.3 and the guide rod sleeve 1.7. The lock tongue 1.5 is installed on the guide pin clamping plate 1.3, and a slide groove is provided on the ladle fixing seat 1.1 corresponding to the guide pin clamping plate 1.3.

[0036] During installation, the guide pin card plate 1.3 is assembled into the slide groove through the square hole. The guide pin card plate 1.3 is allowed to slide in the slide groove. When it slides to the leftmost end, the lock tongue 1.5 enters the lock hole 1.2.1.

[0037] Then fix the guide rod sleeve 1.7 on the outer end surface of the fixed plate 1.1.1 by bolts, then place the spring 1.4 between the guide pin clamping plate 1.3 and the fixed plate 1.1.1 or the guide rod sleeve 1.7, and then insert the lock shaft 1.6 into the guide rod sleeve 1.7, and fix the inner end to the guide pin clamping plate 1.3 with an elastic gasket through a threaded manner. At this time, the spring is in a compressed state, and the lock tongue on the guide pin clamping plate 1.3 is compressed into the lock hole of the guide pin 1.2.

[0038] That is, the spring lock shaft is used to drive the lock tongue into the lock hole and drive the guide pin clamping plate close to the guide pin under the action of the spring force.

[0039] The guide pin clamp 1.3 is used to withstand the pushing force of the ladle 2 during the falling process of the ladle 2, and transmit the pushing force to the spring lock shaft to separate the lock tongue from the lock hole. After continuing to fall into place, the perforation on the ladle 2 is aligned with the position of the guide pin clamp 1.3, the guide pin clamp 1.3 loses its constraint and resets under the action of the spring, locking the lock tongue into the lock hole to achieve locking of the ladle.

[0040] The lock shaft unlocking assembly includes a handle 1.8 for moving the spring lock shaft away from the guide pin and a movable clamping plate 1.9 for locking the spring lock shaft so that it is away from the guide pin. Specifically, in this embodiment, the lock shaft 1.6 is provided with a first pin shaft 1.1.3 in the area outside the guide rod sleeve 1.7, and the outer end of the fixed plate 1.1.1 is provided with a second pin shaft 1.1.4 through an extension arm 1.1.2. The middle part of the handle 1.8 is hinged to the first pin shaft 1.1.3, and the action part of the handle 1.8 is provided with a shift fork and is clamped on the second pin shaft 1.1.4. The end of the handle 1.8 away from the shift fork is the hand-held end, so as to form a swinging mechanism around the shift fork and the second pin shaft as a rotating pair, driving the lock shaft to move toward the outer end.

[0041] An annular notch 1.11 is provided at the outer end of the lock shaft 1.6, and the movable clamping plate 1.9 can be movably clamped into the notch to lock the lock shaft.

[0042] Specifically, a cone head 1.10 is provided at the outer end of the lock shaft, the notch 1.11 is located at the inner end of the cone head 1.10, the movable clamping plate 1.9 is a rocker structure with a counterweight, and the movable clamping plate is installed on the guide rod fixing seat. The guide rod fixing seat and the ladle fixing seat are separately provided to facilitate adjustment of the relative position relationship.

[0043] The cone head 1.10 is used to push the movable clamping plate 1.9 to swing and make way. After the movable clamping plate 1.9 enters the range of the slot 1.11, it is reset under the action of the counterweight and is clamped into the slot 1.11 to be locked.

[0044] Brief description of the working process:

[0045] When the ladle falls, the guide pin 1.2 enters the guide hole of the bottom plate of the ladle fixing seat 1.1, and the guide pin clamping plate 1.3 is forced back by the ladle under the action of the conical structure of the guide pin 1.2. When the ladle falls to the bottom, the lock hole, the perforation and the lock tongue are aligned, and the guide pin clamping plate 1.3 enters the lock hole of the guide pin 1.2 under the action of the spring 1.4, so that the ladle is automatically fixed to the ladle seat after falling and locked by the spring;

[0046] After the ladle has cooled, the handle 1.8 is manually rotated to make the locking shaft 1.6 slide out to the right until the conical chamfer on the right end of the locking shaft 1.6 contacts the movable clamping plate 1.9, causing the movable clamping plate 1.9 to tilt from the horizontal state to a certain angle. The handle 1.8 is continued to be rotated until the movable clamping plate 1.9 enters the annular notch of the locking shaft 1.6 under the action of gravity. At that time, after the operator evacuates, the ladle is lifted to separate the ladle from the ladle seat.

[0047] At the same time, due to the loss of restraint, the operating movable card plate 1.9 swings slightly and disengages from the annular notch. Under the action of the compression spring 1.4, the lock shaft retracts and returns to its initial position. The movable card plate also returns to its horizontal position under the action of gravity, and the mechanism is reset at this time.

[0048] Finally, it should be noted that: The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
