Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel smelting and processing equipment, specifically a material conveying device for ladle construction. Background Technology
[0002] A ladle (also known as a steel ladle) is a container used in steel mills and foundries to receive molten steel and perform pouring operations before open-hearth furnaces, electric furnaces, or converters. The ladle's structure mainly consists of a high-strength metal outer shell and an inner wall constructed of refractory materials (refractory bricks). Currently, the internal masonry of the ladle is usually completed manually. For larger ladles, due to their size and the considerable height of the masonry, scaffolding needs to be erected and additional personnel are required to assist with material loading during construction. Furthermore, since ladles are typically cylindrical, workers often need to rotate or move the scaffolding after completing a certain section of the masonry to move to another section. This process is inefficient and labor-intensive. Utility Model Content

The gear ring is fixedly fitted onto the lower end of the rotating platform. The rotary drive motor is fixed inside the chassis box. A drive gear is connected to the output shaft of the rotary drive motor. The drive gear meshes with the gear ring to drive the gear ring to rotate.
[0008] Furthermore, the chassis box is a hollow cylindrical box structure.
[0009] Furthermore, the chassis box is also equipped with a plurality of hydraulic cylinders evenly spaced apart. The axes of all hydraulic cylinders are perpendicular to the axis of the chassis box.

Detailed Implementation
[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0021] Please refer to Figures 1 to 3 The present invention relates to a material conveying device for steel ladle construction, comprising a chassis box 1, a turntable 2, a rotary drive assembly, a lifting platform 3, and a lifting drive assembly.
[0022] The masonry at the bottom and lower part of the inner wall of the ladle 6 is pre-built. The chassis box 1 is located inside the ladle 6 and supported at the bottom of the ladle 6. The chassis box 1 is a hollow cylindrical box structure. The chassis box 1 is also provided with a partition plate 11, which divides the space inside the chassis box 1 into a rotating cavity at the top and a locking cavity at the bottom. The locking cavity is provided with a plurality of hydraulic cylinders 12. In this embodiment, there are four hydraulic cylinders 12, all of which are located in the locking cavity and are evenly spaced. The axes of all hydraulic cylinders 12 are perpendicular to the axis of the chassis box 1, that is, adjacent hydraulic cylinders 12 are perpendicular to each other. Each hydraulic cylinder 12 is provided with a telescopic shaft, and each telescopic shaft is provided with a locking push block at its end. The hydraulic cylinders 12 are used to drive the telescopic shaft to extend after the material conveying device is hoisted into the ladle 6, thereby pressing the locking push block against the inner wall of the ladle 6, thereby locking and fixing the chassis box 1 in position inside the ladle 6, ensuring the stability of the entire device during operation.
[0023] The turntable 2 is rotatably mounted on the chassis box 1, and the rotary drive assembly is located inside the chassis box 1. Specifically, a mounting hole is provided on the top of the chassis box 1, and a rotating platform 22 is fixedly connected to the bottom of the turntable 2. The rotating platform 22 is rotatably mounted in the mounting hole through the rotating bearing 13. Thus, the turntable 2 is rotatably mounted on the chassis box 1.
[0024] The rotary drive assembly is located within the rotating cavity and is used to drive the turntable 2 to rotate. The rotary drive assembly includes a gear ring 51 and a rotary drive motor 5. A drive gear is connected to the output shaft of the rotary drive motor 5. Both the drive gear and the rotary drive motor 5 are located within the rotating cavity. The lower end of the rotating platform 22 extends into the chassis box 1. The gear ring 51 is fixedly fitted onto the lower end of the rotating platform 22. The rotary drive motor 5 is fixed to the partition plate 11 inside the chassis box 1. The drive gear meshes with the gear ring 51, thereby causing the rotary drive motor 5 to drive the gear ring 51 and the turntable 2 to rotate.
[0025] The lifting platform 3 is also equipped with a guardrail 33, which has a notch to facilitate personnel going up and down and the handling of masonry materials. The lifting drive assembly is used to drive the lifting platform to rise and fall. Specifically, the lifting drive assembly includes a support plate 4, a lifting drive motor 41, and at least one limiting rod 42. In this embodiment, there are two limiting rods 42. A lifting screw 43 is rotatably provided on the side of the support plate 4. The limiting rod 42, the support plate 4, and the lifting screw 43 are all vertically arranged. The lifting platform 3 has a limiting sleeve 31 and a lifting screw sleeve 32 at both ends. The limiting sleeve 31 and the lifting screw sleeve 32 are respectively fitted onto the limiting rod 42 and the lifting screw 43. The inner wall of the lifting screw sleeve 32 is threadedly engaged with the outer wall of the lifting screw 43. The lifting drive motor 41 is connected to the top of the support plate 4 and is connected to the upper end of the lifting screw 43. It is used to drive the lifting screw 43 to rotate, thereby driving the lifting platform 3 to rise and fall. The lifting platform 3 supports the materials used for the inner wall masonry of the ladle 6 and the workers who masonry the materials.
[0026] Furthermore, the turntable 2 is also provided with multiple lifting rings 21. In this embodiment, there are four lifting rings 21, which facilitates the entire material conveying device to be lifted into the ladle by an overhead crane or crane for operation.
[0027] Understandably, the material conveying device of this utility model also includes a controller, which is connected to the lifting drive motor 41, the rotation drive motor 5 and the hydraulic cylinder 12. The operator controls the locking, lifting and rotation of the material conveying device through the controller.
[0028] The working process of this utility model for a material conveying device for ladle masonry is as follows: First, workers enter the ladle 6 and complete the masonry work on the bottom and lower side walls of the ladle 6. After leaving the ladle 6, the entire device is lifted into the ladle 6 by a gantry crane and supported at the bottom. Next, workers and masonry materials are lifted into the ladle 6. Workers then transport the masonry materials to the lifting platform 3 and stand on it. The lifting drive motor 41 is started, raising the lifting platform 3 to the designated height. The upper part of the inner wall masonry work on the ladle 6 is then started. During the masonry process, workers can control the rotation drive motor 5 to start and stop, controlling the rotation of the rotating platform 22, thereby controlling the lifting platform 3 to rotate to a suitable direction. This allows workers to easily adjust the circumferential position of the masonry work, enabling them to perform masonry work on the inner wall of the ladle 6 from all directions.
[0029] This material conveying device can conveniently move workers and masonry materials to designated positions and directions inside the ladle 6, enabling workers to independently and conveniently complete the all-round masonry of the upper wall of the ladle 6, thereby greatly improving the masonry efficiency of the inner wall of the ladle 6, reducing the difficulty of masonry of the inner wall of the ladle 6, and reducing the manpower required for masonry of the inner wall of the ladle 6.
