Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of continuous casting slab production equipment, specifically to a device for fixing a robotic arm for the ladle of a continuous casting slab. Background Technology
[0002] During the production of continuously cast slabs, after the continuous casting machine stops pouring, the tundish car moves to the baking position, and the used tundish is lifted off. At this time, the robotic arm (usually used to hold long nozzles, etc.) mounted on the ladle may automatically rise under its own weight or the action of the drive mechanism because it is no longer constrained by the weight of the ladle sleeve or other suspended loads. This unconstrained automatic lifting action poses a safety hazard: the robotic arm may collide with surrounding equipment or structures, causing deformation and damage to the robotic arm, affecting subsequent production.
[0003] Currently, regarding the issue of securing the ladle robotic arm when it is not in operation, there is often a lack of dedicated securing devices on site. Operators may use temporary measures (such as binding with wire ropes) to restrict the movement of the robotic arm, but these temporary methods lack reliability and ease of operation. Therefore, there is an urgent need in this field for a device that is simple in structure, easy to install, and safe and reliable, for securing the ladle robotic arm during production breaks or maintenance of continuously cast slabs, to prevent accidental movement and equipment damage. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for fixing a robotic arm for continuously casting slab ladles.
[0005] The specific technical solution is as follows:
[0006] A device for fixing a ladle robotic arm in continuous casting slabs includes a fixed base and a clamping member. The fixed base is fixedly installed on the railing of the tundish car of the continuous casting machine, and the clamping member is movably connected to the fixed base for hooking or releasing the ladle robotic arm, thereby restricting the ladle robotic arm to a predetermined position.
[0007] Optionally, the fixing base is a rectangular steel plate, which is fixedly connected to the intermediate cargo railing.
[0008] Optionally, the rectangular steel plate is fixed to the intermediate cargo railing by welding.
[0009] Optionally, the rectangular steel plate is fixed to the intermediate cargo railing by bolts.
[0010] Optionally, the rectangular steel plate has mounting holes, and the clamping member is connected to the rectangular steel plate through the mounting holes by a fixing screw.
[0011] Optionally, the clamping element is a U-shaped hook.
[0012] Optionally, the U-shaped hook is rotatably mounted on a fixed base via a fixing screw, with the opening of the U-shaped hook facing the side of the large-bag robotic arm.
[0013] Optionally, the thickness of the rectangular steel plate is approximately 10-20 mm.
[0014] Optionally, the shape of the U-shaped hook is adapted to the structure of the robotic arm.
[0015] Optionally, a buffer is provided at the contact point between the U-shaped hook and the robotic arm.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The main components of this device are common parts such as steel plates and U-hooks, which are simple to process and install, and have low cost. The base is welded and fixed to the tundish car railing, and the U-hooks are connected by bolts, making assembly and disassembly convenient. Fixing and unfixing only requires moving the U-hooks, without the need for complicated tools. The U-hooks provide rigid constraints on the robotic arm, effectively preventing accidental movement. The device makes full use of the structure of the tundish car railing, ensuring stable contact with the robotic arm and reliable fixation. When pouring is required, the U-hooks can be quickly removed without interfering with the normal lifting and operation of the ladle robotic arm. In summary, the fixing device provided in this application can reliably fix the ladle robotic arm during the intervals or maintenance of continuous casting slab production, avoiding collision damage caused by free movement of the robotic arm, and improving the safety and lifespan of continuous casting production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0024] This utility model provides a device for fixing a robotic arm for continuously casting slab ladle, referring to... Figures 1-2 It includes a fixed base 2 and a clamping member. The fixed base 2 is fixedly installed on the railing 1 of the tundish car of the continuous casting machine. The clamping member is movably connected to the fixed base 2 for hooking or releasing the ladle robotic arm 5, thereby restricting the ladle robotic arm 5 to a predetermined position.
[0025] In this embodiment, the fixed base 2 is a rectangular steel plate with a thickness of approximately 10-20 mm. The size is selected based on the railing structure and stress conditions. A suitable position is selected on the railing 1 of the tundish car of the continuous casting machine, and the rectangular steel plate is welded and fixed to ensure that the plane of the steel plate is perpendicular to the plane of motion of the robotic arm. A mounting hole (with a diameter slightly larger than the diameter of the fixing screw 4) is pre-drilled in the upper right corner of the rectangular steel plate. The clamping component is a U-shaped hook 3, which is made of round steel and has an opening width slightly larger than the thickness of the tundish robotic arm 5 to facilitate hooking. The straight section of the U-shaped hook 3 has a through hole. A fixing screw 4 passes through the mounting hole on the steel plate and the through hole of the U-shaped hook 3 to rotatably connect the U-shaped hook 3 to the rectangular steel plate. The end of the fixing screw 4 is equipped with a nut to prevent the U-shaped hook 3 from falling off.
[0026] After continuous casting is completed, the tundish car is moved into position and lifted off the tundish, the ladle robotic arm 5 is lowered to a position close to the tundish car railing 1. At this time, the U-hook 3 is rotated around the fixing screw 4 to the bottom of the robotic arm, and then the U-hook 3 is lifted upwards so that its opening locks onto a suitable part of the robotic arm (such as the lower flange or connecting rod of the robotic arm). Because the U-hook 3 is supported by the fixing screw 4 and the steel plate, the robotic arm is fixed after being hooked and cannot move upwards on its own. This achieves reliable fixation of the ladle robotic arm 5, preventing it from rising unrestrained and colliding with surrounding equipment.
[0027] When re-pouring is required, first rotate the U-hook 3 downwards away from the robotic arm, releasing the large ladle robotic arm 5 from its fixation. Then, raise or move the robotic arm away to proceed with the subsequent intermediate ladle installation and pouring operations. The entire fixing and releasing process is simple to operate and does not affect the normal production rhythm.
[0028] In other embodiments, the fixed base 2 may also adopt other shapes and fixing methods, such as using steel plates or structural steel with reinforcing ribs, and fixing it to the railing by bolts instead of welding, so as to facilitate disassembly. The shape and size of the U-shaped hook 3 can be adjusted according to the structure of the robotic arm, for example, using a longer hook body or different opening angles, to accommodate different models of large-bag robotic arms 5.
[0029] In addition, a rubber pad or other buffer can be added at the contact point between the U-shaped hook 3 and the robotic arm to reduce the impact and wear on the robotic arm during hooking.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
