Technical Field

[0001] This utility model relates to the field of steel component processing technology, specifically to a positioning device for a ladle rotary table. Background Technology

[0002] A ladle turret is an important piece of equipment in the metallurgical industry used to support and rotate ladles for continuous casting. In actual production, the ladle needs to be securely mounted on the turret using a positioning device and can be switched quickly and smoothly with the turret.

[0003] However, most existing ladle turrets use fixed placement slots. This fixed limiting structure cannot adapt to ladle bodies of different sizes and specifications, resulting in unstable placement, tilting, or even slippage of the ladle, affecting the safety and stability of the casting operation.

[0004] This necessitates an adjustable positioning device for the ladle rotary table. Utility Model Content

[0005] The technical problem this invention aims to solve is that the fixed limiting structure makes it difficult to apply to ladles of different sizes. The invention provides a positioning device for an adjustable ladle turntable.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a positioning device for a ladle slewing table, comprising a slewing support table, a slewing frame, a ladle body, and a positioning support mechanism;

[0008] The positioning support mechanism includes a fixed plate, a positioning plate, and an adjustment mechanism. The fixed plate is welded and fixed to the outer wall of the rotating frame. The positioning plate is set on the other side of the fixed plate, and a pair of them are mirror images of each other. The two positioning plates move closer or further apart under the action of the adjustment mechanism. After the ladle body is placed between the two positioning plates, it is placed stably through the positioning groove of the positioning plate, thus providing positioning support for ladle bodies of different sizes.

[0009] As an improvement, the lifting and rotating mechanism includes a rotating block and a lifting block;

[0010] After the slewing block is connected to the top surface of the slewing support platform via a slewing motor, a lifting groove is vertically opened in the center. After the lifting block is slidably placed in the lifting groove, it moves up and down under the action of a hydraulic cylinder. The slewing frame and the lifting block are detachably connected.

[0011] As an improvement, the rotating frame is adapted to the rotating block, and after the bottom is open, it is placed on the rotating block. The rotating frame has a pre-set connecting through hole. After the bolt passes through the connecting through hole, it is threadedly connected with the pre-set threaded hole on the lifting block.

[0012] As an improvement, a rectangular positioning groove is opened in the center of the top surface of each positioning plate. After each ladle body is placed between two positioning plates, a pair of positioning blocks that are locked into the positioning groove are welded and fixed to the outer wall of the ladle body.

[0013] As an improvement, the adjustment mechanism includes a groove and a two-way hydraulic telescopic rod;

[0014] After the two fixed plates are welded and fixed to the outer walls of the two sides of the rotating frame, a groove is opened on the side away from the rotating frame. The positioning plates slide in the groove through the slider. After the bidirectional hydraulic telescopic rod is fixedly set in the center of the groove, the two output ends are fixedly connected to the sliders of the two positioning plates respectively.

[0015] As an improvement, an auxiliary positioning mechanism is also included. The auxiliary positioning mechanism is connected between the two positioning plates of each positioning support mechanism and is provided in a mirror image. The auxiliary positioning mechanism includes a first link, a second link and a support plate.

[0016] After connecting rod one is hinged to the end of a positioning plate, connecting rod two is hinged to the other end, and the other end of connecting rod two is hinged to the end of another positioning plate. The support plate is fixedly installed on the hinge rod between connecting rod one and connecting rod two. After the ladle body is placed between the two positioning plates, the hinge joint of connecting rod one and connecting rod two is close to the side wall of the ladle body, and the support plate is close to the bottom surface of the ladle body.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. By setting up an adjustment mechanism consisting of a pair of mirror-arranged positioning plates and a bidirectional hydraulic telescopic rod, the distance between the two positioning plates can be automatically adjusted according to the size of the ladle, which is suitable for ladle bodies of different diameters or shapes, thus improving versatility;

[0019] 2. The positioning plate is provided with a rectangular positioning groove, which, together with the positioning block on the outer wall of the ladle, achieves precise fitting and positioning;

[0020] 3. An auxiliary positioning mechanism is set up so that after the positioning plate clamps the ladle, the connecting rod hinge is pressed against the side walls on the other two sides of the ladle, and the support plate is pressed against the bottom surface of the ladle, forming a multi-point support structure, which significantly improves the overall stability.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0028] A positioning device for a ladle rotary table, combined with an attached Figure 1-3As shown, the system includes a slewing support platform 1, a slewing frame 2, a ladle body 3, and a positioning support mechanism. The top surface of the slewing support platform 1 is connected to the slewing frame 2 via a lifting and slewing mechanism, which includes a slewing block 7 and a lifting block 8. The slewing block 7 is connected to the top surface of the slewing support platform 1 via a slewing motor, and a vertical lifting groove 9 is vertically formed in its center. The lifting block 8 is slidably positioned within the lifting groove 9 and moves up and down under the action of a hydraulic cylinder. The lifting and slewing mechanism integrates hydraulic lifting and motor-driven slewing functions and can be controlled by a PLC system. The rotating frame 2 and the lifting block 8 are detachably connected. The rotating frame 2 is compatible with the rotating block 7, and after the bottom is open, it is placed on the rotating block 7. The rotating frame 2 has a pre-set connection through hole 10. After the bolt passes through the connection through hole 10, it is threadedly connected with the pre-set threaded hole 11 on the lifting block 8. The rotating frame 2 and the lifting block 8 are connected by bolts, which is convenient for disassembly and replacement. If it is necessary to replace the ladle or repair the equipment, simply loosen the bolts to remove the rotating frame 2 from the rotating block 7.

[0029] A pair of ladle bodies 3 are provided and are respectively fixed to both sides of the rotating frame 2 by positioning support mechanisms. The positioning support mechanism includes a fixed plate 4, a positioning plate 5 and an adjustment mechanism. The fixed plate 4 is welded and fixed to the outer wall of the rotating frame 2. The positioning plate 5 is set on the other side of the fixed plate 4 and is mirrored in a pair. The two positioning plates 5 move closer or further apart under the action of the adjustment mechanism. After the ladle body 3 is placed between the two positioning plates 5, it is placed stably by the positioning groove 6 of the positioning plate 5. A rectangular positioning groove 6 is opened in the center of the top surface of each positioning plate 5. After each ladle body 3 is placed between the two positioning plates 5, a pair of positioning blocks 12 that are inserted into the positioning groove 6 are welded and fixed to the outer wall of the ladle body 3 to provide positioning support for ladle bodies 3 of different sizes. The rectangular positioning groove 6 cooperates with the positioning blocks 12 on the outer wall of the ladle to achieve precise fitting and positioning.

[0030] The adjustment mechanism includes a groove 13 and a bidirectional hydraulic telescopic rod 14; after the two fixed plates 4 are welded and fixed to the outer walls of the two sides of the rotating frame 2, a groove 13 is opened on the side away from the rotating frame 2, and the positioning plates 5 slide in the groove 13 through the sliders 15. After the bidirectional hydraulic telescopic rod 14 is fixedly set in the center inside the groove 13, the two output ends are fixedly connected to the sliders 15 of the two positioning plates 5 respectively. Example 2

[0031] Based on Example 1, combined with Appendix Figure 4As shown, it also includes an auxiliary positioning mechanism, which is connected between the two positioning plates 5 of each positioning support mechanism, and a pair is arranged in a mirror image. The auxiliary positioning mechanism includes a first connecting rod 16, a second connecting rod 17, and a support plate 18. The first connecting rod 16 is hinged to one end of a positioning plate 5, and the other end is hinged to the second connecting rod 17. The other end of the second connecting rod 17 is hinged to the end of another positioning plate 5. The support plate 18 is fixedly installed on the hinged rod between the first connecting rod 16 and the second connecting rod 17. After the ladle body 3 is placed between the two positioning plates 5, the hinge joint of the first connecting rod 16 and the second connecting rod 17 is close to the side wall of the ladle body 3, and the support plate 18 is close to the bottom surface of the ladle body 3. When the positioning plate 5 clamps the ladle, the hinge joint of the connecting rod is close to the side wall of the ladle, and the support plate 18 is close to the bottom surface of the ladle, forming a multi-point support structure, which significantly improves the overall stability.

[0032] In a specific implementation of this utility model, the rotary support platform 1 is installed on a designated foundation, the rotary frame 2 is connected to the lifting block 8 by bolts, and the connection through hole 10 is aligned with the threaded hole 11 and tightened.

[0033] Start the bidirectional hydraulic telescopic rod 14 to move the two positioning plates 5 to the sides, leaving enough space to put in the ladle. Place the ladle body 3 between the two positioning plates 5 so that its bottom contacts the support plate 18. The positioning block 12 on the outer wall of the ladle is embedded in the positioning groove 6. The hydraulic system drives the bidirectional telescopic rod to retract, causing the two positioning plates 5 to move closer to each other until the sides contact the hinge part of the connecting rod. The positioning block 12 on the outer wall of the ladle is completely embedded in the positioning groove 6.

[0034] The hydraulic cylinder is started to move the lifting block 8 up and down to adjust the height of the ladle. The rotary motor is started, and the rotary block 7 drives the entire rotary frame 2 and the ladle to rotate, thus completing the ladle switching or casting position adjustment.

[0035] The present invention and its embodiments have been described above.
