Description

Technical Field

[0001] The utility model relates to the technical field of copper smelting equipment, in particular to a ladle anti - detachment device. Background Technique

[0002] In the process of copper smelting, the ladle is used to temporarily hold the molten blister copper and is the main container for pouring operations. The overhead crane usually uses a plate hook to lift the ladle. However, due to reasons such as the large inertia of the ladle, sudden stops and starts, and operation errors, there is a risk of the ladle becoming unhooked during the lifting process, which poses a serious threat to production safety. At the same time, the ladle is a special operation equipment and its internal stress cannot be directly modified to prevent performance changes caused by internal stress. Therefore, it is necessary to design a ladle anti - unhooking device for the overhead crane in copper smelting to improve the production safety coefficient without damaging the internal stress structure of the ladle. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems raised in the background technique and design a ladle anti - detachment device.

The two sides of the ladle body are fixedly installed with bases, the bases are fixedly installed with hoisting pipes, the other ends of the hoisting pipes are fixedly installed with ladle lifting lugs, and the anti - detachment device is installed on the ladle lifting lugs.

[0005] Preferably, the anti - detachment device includes a movable plate, an installation slot, and a fixed seat. The anti - detachment device is installed on the ladle lifting lug through the installation slot, the other side of the installation slot is provided with a fixed seat, and the lower half of the anti - detachment device is a movable plate.

[0006] Preferably, the fixed seats are connected by a fixed rod.

[0007] Preferably, a connecting rod is fixedly provided on one side of the anti - detachment device close to the base.

[0008] Preferably, a hook is connected to the hoisting pipe, and a connecting groove is opened in the hooked part of the hook.

[0009] Beneficial Effects:

[0010] The utility model provides a ladle anti - detachment device, which has the following beneficial effects. Through its structural design, the device installs a movable plate on the ladle lifting lug, so as to position the hook through the movable plate during the hoisting by the crane, playing a role of automatic deviation correction. The connecting rod on the movable plate and the connecting groove on the hook are used to connect the movable plate and the hook, enabling the hook and the movable plate to rotate synchronously on the lifting pipe, thereby preventing the ladle from unhooking due to inertia when the hoisting ends.

[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0016] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper / lower end", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "set / sleeved with", "socket connection", "connection", etc. should be understood in a broad sense. For example, "connection" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] Please refer to Figure 1 -3. The present utility model provides a technical solution: a ladle anti - detachment device, including a ladle 1, a base 3, a lifting pipe 7, a ladle lifting lug 8, and an anti - detachment device 9. It is characterized in that the base 3 is fixedly installed on both sides of the ladle 1 body, the lifting pipe 7 is fixedly installed on the base 3, the other end of the lifting pipe 7 is fixedly installed with a ladle lifting lug 8, and the anti - detachment device 9 is installed on the ladle lifting lug 7.

[0019] The anti - detachment device 9 includes a movable plate 4, an installation slot 10, and a fixed seat 5. The anti - detachment device 9 is installed on the ladle lifting lug 8 through the installation slot 10. The other side of the installation slot 10 is provided with a fixed seat 5. The lower half of the anti - detachment device 9 is a movable plate 4, which is installed on the ladle lifting lug 8 through the installation slot 10. It neither modifies the ladle 1 body nor allows the movable plate 4 to rotate freely. The fixed seats 5 are connected by a fixed rod 6 to strengthen the fixation by using the fixed rod 6. One side of the anti - detachment device 9 close to the base 3 is fixedly provided with a connecting rod 11. A hook 2 is connected to the lifting pipe 7, and a connecting slot 12 is opened in the hooked part of the hook 2. During hoisting, the connecting rod 11 fits with the connecting slot 12, so that the hook 2 and the movable plate 4 can rotate synchronously.

[0020] In this implementation scheme:

[0021] During operation, the movable plate 4 is installed on the ladle lifting lug 8 through the installation slot 10, and then the movable rod 4 is further fixed to the ladle lifting lug 8 through the fixed seat 5 and the fixed rod 6. When the ladle 1 needs to be hoisted, the hook 2 is hung on the lifting pipe 7 by using the factory overhead crane, and at the same time, the connecting rod 11 on one side of the movable plate 4 fits with the connecting slot 12 on the hook 2, so that the hook 2 and the movable rod 4 can rotate synchronously. At this time, the hook 2 is between the movable plate 4 and the base 3. When reaching the hoisting location, command the overhead crane to release the hook 2, so that the connecting rod 11 and the connecting slot 12 are separated, and the hook 2 can be detached from the ladle 1 to complete the hoisting.

[0022] It should be noted that, in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
