The continuous casting machine vibration table is an important component of the continuous casting machine equipment. It is mainly used to ensure the smooth forming of the billet during the continuous casting process, reduce or avoid the adhesion between the billet and the crystallizer, and promote the improvement of the billet surface quality.

[0003] The patent with the publication number CN218361965U discloses a crystallizer vibration table for a square billet continuous casting machine, which belongs to the field of vibration tables and includes a base, a mounting seat, a vibrator, and an auxiliary mechanism. Four vibrators are installed on the base, and the vibrator includes a mounting shell, a rotating shaft, a transmission rod and a limit sleeve. The rotating shaft is rotatably mounted at the lower end of the mounting shell, and a cam group is arranged on the rotating shaft; by arranging the vibrator, utilizing the sliding ability of the impact piece in the mounting shell, and the rotation ability between the cam group, the transmission rod and the impact piece, the impact piece is driven to slide up and down when the rotating shaft rotates, and the impact piece hits the first limit ring on the limit sleeve when it moves upward, so that when the rotating shaft rotates, the impact piece will reciprocate up and down, thereby forming a regular vibration to prevent the inner wall of the crystallizer from sticking, and by arranging the auxiliary mechanism, utilizing the transmission relationship between the sprocket and the chain, when the motor is working, it can simultaneously drive the two rotating shafts on the same side to rotate, thereby ensuring the consistency of vibration.

[0004] However, the following problems still exist in the above-mentioned continuous casting machine vibration table:

[0005] When the above-mentioned continuous casting machine vibration table is in use, the rotating shaft drives the transmission rod to rotate, and then drives the impact member to reciprocate up and down, so as to drive the mounting seat to vibrate up and down. However, the impact member will frequently collide with the first limit ring during the frequent up and down movement, and it is easy to be worn or even deformed. However, the above-mentioned impact member and the first limit ring are all located inside the mounting shell, which is not convenient for disassembly, maintenance and replacement, which is relatively inconvenient.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 5 , a vibration table for a continuous casting machine which is easy to maintain, comprises a base 1, two transmission mechanisms 12, four limit sleeves 8 and a mounting seat 2, the upper surfaces of the four limit sleeves 8 are fixedly connected to the bottom surface of the mounting seat 2, the upper surface of the base 1 is connected with four groups of support components, the four groups of support components are respectively connected to the two transmission mechanisms 12, the interiors of the four groups of support components are connected with U-shaped rotating blocks 11, the inner walls of the four U-shaped rotating blocks 11 are sleeved and rotatably connected to transmission rods 6, the other ends of the four transmission rods 6 are rotatably connected with impact members 4, the other ends of the four impact members 4 are respectively against the bottom surfaces of the four limit sleeves 8, the bottom surface of the mounting seat 2 is connected with four sleeves 3, the inner walls of the four sleeves 3 are respectively slidably connected to the outer walls of the four impact members 4 and the four limit sleeves 8, the center position of the upper surface of the base 1 is connected with a lifting mechanism, and the output end of the lifting mechanism is connected to the bottom surface of the mounting seat 2.

[0024] The vibrating table for continuous casting machine which is easy to maintain in the utility model is similar in structure to the existing vibrating table for continuous casting machine, such as the vibrating table for crystallizer of square billet continuous casting machine disclosed in the patent with publication number CN218361965U. Figures 1 to 5 As shown, when the easy-to-maintain continuous casting machine vibration table in the utility model is in use, the transmission mechanism 12 will drive the four U-shaped rotating blocks 11 inside the four groups of supporting components to rotate, and then drive the four transmission rods 6 to rotate. After the four transmission rods 6 rotate, they will drive the four impact members 4 to move up and down inside the four sleeves 3, so that the four impact members 4 can continuously impact the four limit sleeves 8, and then the crystallizer of the continuous casting machine on the mounting seat 2 can be kept in a vibrating state through the four limit sleeves 8.

[0025] After using for a period of time, because the impact piece 4 and the limit sleeve 8 are frequently in a collision state, a certain degree of deformation and damage will occur. At this time, the lifting mechanism can be opened by an external controller. After the lifting mechanism is started, the mounting seat 2, the four limit sleeves 8 and the four sleeves 3 are forced to rise until the four impact pieces 4 are separated from the sleeves 3 and stop. At this time, the U-shaped rotating block 11, the transmission rod 6 and the impact piece 4 can be repaired or replaced by disassembling the support assembly; and then the limit sleeve 8 inside the sleeve 3 can be repaired or replaced by disassembling the sleeve 3, which is convenient and easy to operate.

[0026] Special mention should be made here:

[0027] The structures and implementation principles of the above-mentioned limiting sleeve 8, transmission mechanism 12, base 1 and mounting seat 2 are the same as those of a crystallizer vibration table of a square billet continuous casting machine disclosed in the patent with publication number CN218361965U.

[0028] The external controller is a common technology at present, so it will not be described in detail.

[0029] Please refer to Figure 1-Figure 5 The support assembly includes two support blocks 7, wherein the bottom surface of one support block 7 is fixedly connected to the upper surface of the base 1, and the bottom surface of the other support block 7 is slidably connected to the upper surface of the base 1. The outer wall of the transmission mechanism 12 passes through the support block 7 fixedly connected to the base 1, and is fixedly connected to one end of the U-shaped rotating block 11, and the other end of the U-shaped rotating block 11 is slidably connected to the inner wall of the other support block 7.

[0030] More specifically, under normal circumstances, the U-shaped swivel block 11 and the transmission rod 6 rotate between the two support blocks 7. When the U-shaped swivel block 11, the transmission rod 6 and the impact piece 4 need to be replaced, it is only necessary to loosen the support block 7 that is slidably connected to the base 1 so that the U-shaped swivel block 11, the transmission rod 6 and the impact piece 4 can be removed from this side and then can be repaired or replaced.

[0031] Please refer to Figure 1 and Figure 2 Four moving grooves 101 are formed on the upper surface of the base 1, and a moving block 13 is fixedly connected to the bottom surface of the support block 7 which is slidably connected to the base 1. The outer wall of the moving block 13 is slidably connected to the inner wall of the moving groove 101 and is fastened by bolts.

[0032] More specifically, by providing the moving groove 101 and the moving block 13, firstly, the moving track of the support block 7 can be limited; secondly, by fastening with bolts, deviation of the support block 7 during normal operation can be avoided.

[0033] Please refer to Figure 2 The lifting mechanism includes a cylinder 9 and a support plate 10. The outer wall of the cylinder 9 is fixedly connected to the upper surface of the base 1, the output end of the cylinder 9 is fixedly connected to the bottom surface of the support plate 10, and the other side of the support plate 10 is against the bottom surface of the mounting seat 2.

[0034] More specifically, when the U-shaped rotating block 11, the transmission rod 6 and the impact member 4 need to be replaced, the cylinder 9 is turned on by the external controller. After the cylinder 9 is started, the output end rises, and then the support plate 10 can be pushed outward, so that the upper mounting seat 2 can be lifted. It should be noted here that: a number of springs are installed on the base 1, so when the cylinder 9 is subsequently retracted, the mounting seat 2 will be pulled back to its original position again under the action of the springs, and the support plate 10 is not directly connected to the mounting seat 2, and will not affect the vibration of the mounting seat 2 during normal operation.

[0035] Please refer to Figure 5 Two slide grooves 301 are symmetrically provided on one side of the sleeve 3 away from the mounting seat 2 , the inner walls of the two slide grooves 301 are slidably connected with slide plates 5 , and the adjacent sides of the two slide plates 5 are slidably connected with the outer wall of the impact member 4 respectively.

[0036] More specifically, by providing the slide groove 301 and the slide plate 5, after the impact piece 4 is replaced, because one end of the impact piece 4 is rotatably connected to the transmission rod 6, and the other end of the transmission rod 6 is rotatably connected to the U-shaped rotating block 11, the impact piece 4 will collapse to one side in the absence of external obstruction. At this time, the mounting seat 2 can be controlled to descend a certain distance by the cylinder 9, and then the two slide plates 5 are slid out so that the impact piece 4 is located between the two slide plates 5. Then, the other three impact pieces 4 are placed between the two slide plates 5 in the same way, and then the mounting seat 2 is controlled to descend again, and the four impact pieces 4 are inserted into the four sleeves 3. Because the height of the slide plate 5 is not greater than the transmission rod 6, it will not affect the normal rotation between the transmission rod 6 and the U-shaped rotating block 11.

[0037] Please refer to Figure 1-Figure 5, the two slide plates 5 are respectively located on both sides of the U-shaped rotating block 11. Because the impact member 4 and the transmission rod 6 rotate with the central axis of the U-shaped rotating block 11, the two slide plates 5 are arranged on both sides of the U-shaped rotating block 11 to avoid collapse.

[0038] Please refer to Figure 1-Figure 5 The upper surface of the sleeve 3 is fastened to the bottom surface of the mounting seat 2 by bolts. By setting the sleeve 3 and the mounting seat 2 to be bolted, when the limiting sleeve 8 inside the sleeve 3 needs to be repaired or replaced, the sleeve 3 can be removed by simply removing the bolts, which is convenient and quick.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
