Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a loading and unloading device for a continuous casting roll welding machine. Background Technology

[0002] Continuous casting rolls are core components of continuous casting machines. Operating under harsh conditions of high temperature, high load, and rapid heating and cooling, they are prone to wear, cracks, and other defects, requiring regular welding repair. Currently, the loading and unloading of continuous casting roll billets onto the welding machine mainly relies on overhead crane hooks or manual handling. These methods have the following drawbacks: 1) Alignment is difficult, making it hard to ensure precise alignment between the roll axis and the machine tool's ejector pin axis, affecting welding quality; 2) Inefficiency and safety hazards, especially in high-temperature welding environments. Other methods, equipped with loading and unloading devices, have complex structures, occupy significant space next to the welding machine, and are poorly adaptable to different specifications of continuous casting rolls, making them difficult to integrate into automated welding production lines.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 and Figure 2 As shown, this utility model provides a loading and unloading device for a continuous casting roll welding machine, including a base frame 1, a transfer trolley 2, and a support bracket 3, wherein:

[0028] The base frame 1 is located on one side of the surfacing machine body. The base frame 1 is provided with linear slide rails 4 arranged facing the surfacing machine body. A slide block 5 is mounted on the linear slide rail 4. The slide block 5 is driven by the walking drive component to move back and forth along the linear slide rail 4.

[0029] The transfer trolley 2 is rotatably mounted on the slide 5 and is driven by the rotary drive assembly to switch between a first angle and a second angle;

[0030] The support bracket 3 is set on both sides of the transfer trolley 2 and is driven by the translation and lifting assembly to move laterally and vertically relative to the transfer trolley 2. The support bracket 3 is used to support unprocessed or processed continuous casting roll workpieces.

[0031] When the transfer trolley 2 is at the first angle on the slide 5, the bearing bracket 3 on one side of the transfer trolley 2 faces the body of the welding machine so as to lift the continuous casting roll workpiece for the welding machine body to clamp.

[0032] When the transfer trolley 2 is at the second angle on the slide 5, the bearing bracket 3 on the other side of the transfer trolley 2 faces the body of the welding machine so as to receive the continuous casting roll workpiece output from the body of the welding machine.

[0033] Thus, through the coordinated design of the base frame 1, the transfer trolley 2, and the support bracket 3, the automatic loading and unloading of continuous casting roll workpieces to the surfacing welding machine is realized, effectively solving the problems of difficult centering, low efficiency, and safety hazards of traditional manual or hoisting methods. Furthermore, through the rotation switching function of the transfer trolley 2 and the translation and lifting function of the support bracket 3, the rapid conversion and assembly line operation of unprocessed and processed continuous casting roll workpieces are realized, significantly improving the efficiency and automation level of surfacing welding production.

[0034] In at least one embodiment, the support bracket 3 includes a plurality of fork plates 3a, each fork plate 3a being arranged vertically and parallel at intervals. The upper surface of each fork plate 3a is provided with a notch 3b, thereby forming a placement cavity for limiting the continuous casting roll workpiece on the support bracket 3. Further, the notch 3b is inverted trapezoidal.

[0035] Several vertically and parallelly spaced fork plates 3a form a stable, lightweight, and highly versatile bracket structure, while reducing the contact area with the continuous casting roll workpiece, facilitating the placement and removal of the continuous casting roll workpiece when docking with the welding body; the inverted trapezoidal notch 3b has good guiding properties, making it easy for the continuous casting roll workpiece to slide in, and can achieve a self-centering effect, allowing the continuous casting roll workpiece to fall naturally into a stable position, facilitating accurate docking with the welding body.

[0036] In at least one embodiment, the translation and lifting assembly includes a lifting plate 6 and a translation plate 7. A vertical guide rail 8 is provided on the side of the transfer trolley 2, and a first slider 9 is provided on the vertical guide rail 8. The lifting plate 6 is fixedly connected to the first slider 9. A first rack 10 parallel to the vertical guide rail 8 is provided on the inner surface of the lifting plate 6. A first motor 11 is provided inside the transfer trolley 2. The output shaft of the first motor 11 passes through the transfer trolley 2 and is driven by the first rack 10 through a first gear 12. A transverse guide rail 13 and a second rack 14 parallel to the transverse guide rail 13 are provided on the outer surface of the lifting plate 6. A second slider 15 is provided on the transverse guide rail 13. The translation plate 7 is fixedly connected to the second slider 15. A second motor 16 is provided on the outer surface of the translation plate 7. The output shaft of the second motor 16 passes through the translation plate 7 and is driven by the second rack 14 through a second gear 17. A support bracket 3 is installed on the translation plate 7.

[0037] In this system, the first motor 11 operates, and the first gear 12 engages with the first rack 10, causing the lifting plate 6 to move vertically relative to the transfer trolley 2 under the combined action of the vertical guide rail 8 and the first slider 9. The second motor 16 operates, and the second gear 17 engages with the second rack 14, causing the translation plate 7 to move laterally relative to the lifting plate 6 under the combined action of the horizontal guide rail 13 and the second slider 15. Thus, the translation and lifting assembly achieves smooth and precise bidirectional movement of the support bracket 3, ensuring stable and reliable operation, maintaining stability and rigidity during lifting and translation movements, and effectively resisting the overturning moment caused by the load.

[0038] In at least one embodiment, a slewing bearing 18 is provided between the transfer trolley 2 and the slide 5. The inner ring of the slewing bearing 18 is fixed to the slide 5, and the outer ring of the slewing bearing 18 is fixed to the bottom of the transfer trolley 2. An external gear ring is provided on the surface of the outer ring of the slewing bearing 18. The rotation drive assembly includes a third motor 19, and the output shaft of the third motor 19 is driven by the external gear ring through a third gear.

[0039] By driving the slewing bearing 18 with the third motor 19, the transfer trolley 2 can rotate 360° flexibly and precisely relative to the slide 5, and can withstand complex loads such as axial force, radial force and overturning moment, making the transfer trolley 2 structurally stable and reliable when rotating and bearing load.

[0040] In at least one embodiment, a third rack 20 is provided on the base frame 1, which is arranged parallel to the linear slide rail 4. The walking drive assembly includes a fourth motor 21 mounted on the slide block 5. The output shaft of the fourth motor 21 is driven by the third rack 20 through a fourth gear.

[0041] When the fourth motor 21 is running, the fourth gear and the third rack 20 cooperate, and the slide 5 moves horizontally under the guidance of the linear slide rail 4, so as to realize the walking function of the transfer trolley 2, so that the bearing bracket 3 carries the continuous casting roll workpiece and moves back and forth relative to the welding machine body.

[0042] Optionally, the support bracket 3 is installed on two opposite sides of the transfer trolley 2, with the difference between the first angle and the second angle being 180°.

[0043] Here, a dual-station example is taken with two opposing sides of the support bracket 3. The transfer trolley 2 can carry the unprocessed continuous casting roll workpiece to the welding machine body at one station. After rotating 180°, the processed continuous casting roll workpiece can be taken by the other station, realizing the unloading function of the welding machine body. This enables efficient and continuous operation, reduces the idle movement time of the transfer trolley 2, and significantly improves work efficiency.

[0044] In summary, the loading and unloading device for the continuous casting roll surfacing machine achieves fully automatic loading and unloading of continuous casting roll workpieces through the coordinated control of linear movement of slide block 5, rotational switching of transfer trolley 2, and lifting and translation of bearing bracket 3. It effectively solves the problems of difficult centering and low efficiency of manual loading and unloading, significantly improves the degree of production automation and operational safety, has a compact structure, strong versatility, and is easy to integrate into automated surfacing production lines.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
