Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a rotating roller table for casting billets and a continuous casting machine production system. Background Art

[0002] In the steel plant workshop, due to space limitations, the center line of the continuous casting machine and the center line of the hot delivery are not in the same straight line. At this time, the billet needs to change its running direction during the production process. In order to ensure production continuity, it is necessary to realize the online steering of the billet through a rotating roller. The rotating roller can rotate the running direction of the billet 90 degrees by rotating itself. The existing rotating roller can only achieve ±90 degrees of rotation, which means that to complete a billet steering cycle, the rotating roller needs to rotate 90 degrees in the forward direction and then 90 degrees in the reverse direction, a total of 180 degrees. The work efficiency is low and cannot meet the needs of rapid billet drawing of the continuous casting machine. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Solution 1

[0039] The utility model provides a rotating roller table for casting billets, such as Figure 1-Figure 7 As shown, it includes: a slewing support mechanism 10, a rotating mechanism 20, a rotating motor 23, a circular track 30 and an electrical slip ring 40. The rotating mechanism 20 is used to support the ingot. The slewing support mechanism 10 is arranged in the circular track 30. The rotating mechanism 20 is rotatably connected to the slewing support mechanism 10. The rotating mechanism 20 is installed on the circular track 30. The rotating motor 23 is installed on the rotating mechanism 20. The rotating motor 23 is used to provide power to drive the rotating mechanism 20 to rotate along the circular track 30 and rotate relative to the slewing support mechanism 10. The electrical slip ring 40 is installed on the slewing support mechanism 10 and connected to the rotating mechanism 20. The cable of the rotating motor 23 is connected to the rotating end 41 of the electrical slip ring 40.

[0040] The rotating roller for the ingot provided by the utility model can be installed between the continuous casting machine 71 and the hot delivery device 72. After the ingot is transferred to the rotating mechanism 20, the rotating motor 23 drives the rotating mechanism 20 to rotate along the circular track 30, thereby driving the ingot to complete the turning.

[0041] The rotating mechanism 20 rotates around the slewing support mechanism 10, and the external cable is connected to the fixed end 42 of the electrical slip ring 40. The rotating end 41 of the electrical slip ring 40 is connected to the cable of the rotating motor 23, so that the external cable can continuously transmit power and signals to the rotating motor 23 during the rotation of the rotating mechanism 20. By adopting the electrical slip ring 40, the power supply and control signal transmission of the rotating motor 23 of the rotating roller are guaranteed, thereby realizing the 360-degree rotation of the rotating roller. Therefore, each time the turning of the billet is completed, the rotating mechanism 20 only needs to rotate 90 degrees, and there is no need to rotate back in the opposite direction, thereby improving the work efficiency, increasing the possibility of billet delivery, and meeting the needs of fast billet drawing of multi-stream square and round billets.

[0042] The rotating roller table of the casting blank provided by the utility model can realize a 360-degree clockwise rotation or a 360-degree counterclockwise rotation.

[0043] In one embodiment, if Figure 2 , Figure 3 and Figure 7 As shown, the slewing support mechanism 10 includes a base shaft 11, a bearing 12 and a rotating seat 13. The base shaft 11 is arranged at the center of the rotating seat 13. The base shaft 11 is connected to the rotating seat 13 through the bearing 12. The rotating seat 13 is fixedly connected to the rotating mechanism 20. The electrical slip ring 40 is installed at the top of the base shaft 11. When the rotating mechanism 20 rotates under the drive of the rotating motor 23, the rotating seat 13 rotates with the rotating mechanism 20, and the base shaft 11 does not rotate with the rotating mechanism 20. The base shaft 11 can remain stationary, and the fixed end 42 of the electrical slip ring 40 can be installed at the top of the base shaft 11 to provide stable support for the electrical slip ring 40.

[0044] Specifically, one end of the base shaft 11 in the slewing support mechanism 10 is fixed to the ground, and the base shaft 11 is matched with the inner ring of the bearing 12; the rotating seat 13 is matched with the outer ring of the bearing 12 and rotates with the rotation of the rotating mechanism 20. The bearing 12 can be a self-aligning thrust bearing.

[0045] Furthermore, the rotating mechanism 20 includes a rotating disk 21 and a plurality of blank feeding rollers 22, the outer ends of the blank feeding rollers 22 are mounted on the circular track 30, the inner ends of the blank feeding rollers 22 are mounted on the rotating disk 21, and the rotating disk 21 is fixedly connected to the rotating seat 13. The fixed end 42 of the electrical slip ring 40 is mounted on the base shaft 11, and the rotating end 41 of the electrical slip ring 40 is connected to the rotating disk 21 through a bracket, and rotates with the rotation of the rotating disk 21, thereby realizing the power supply and control signal transmission when the rotating roller rotates 360 degrees.

[0046] Furthermore, the blank feeding roller 22 is connected to a wheel mechanism 24, the wheel mechanism 24 is installed on the circular track 30, and the rotary motor 23 is used to drive the wheel mechanism 24 to rotate. Figure 2 As shown, the wheel mechanism 24 is installed on four sets of blank feeding rollers 22, and the blank feeding rollers 22 are installed on the rotating disk 21. The rotation of the wheel mechanism 24 drives the blank feeding rollers 22 and the rotating disk 21 to rotate.

[0047] Preferably, each billet feeding roller 22 is provided with two wheel mechanisms 24, each wheel mechanism 24 is connected to a rotating motor 23; preferably, four billet feeding rollers 22 are included, with a total of eight rotating motors 23. When two motors fail, the remaining six motors can still meet the normal working requirements, thereby increasing the service life of the rotating roller. More preferably, the two wheel mechanisms 24 of one billet feeding roller 22 are arranged on both sides of the billet feeding roller 22, respectively, to facilitate the disassembly and assembly of the motor reducer.

[0048] In one embodiment, the rotating disk 21 is provided with a laser detection device for detecting whether the rotating disk 21 is rotated to a predetermined angle, thereby detecting whether the billet on the rotating roller is in place, so as to realize the automatic control of the clockwise and counterclockwise rotation of the rotating roller when feeding the billet. Preferably, 4 groups of laser detection devices are provided on the rotating disk 21, and each group of laser detection devices includes 1 laser detector (not shown in the figure) and 1 reflector (not shown in the figure). These 4 groups of laser detection devices are used to detect whether the billet on the billet feeding roller is in place. A laser detector 60 of the laser detection device is provided outside the rotating roller, and 12 reflectors (not shown in the figure) are arranged on the rotating disk for acceleration, deceleration and stop control of the rotating roller.

[0049] In one embodiment, if Figure 1-Figure 3 As shown, the rotating roller table of the ingot includes a baffle mechanism 50, which is used to block the ingot on the rotating mechanism 20 from moving toward the electrical slip ring 40 to achieve a buffered stop of the ingot. At the mechanical level, it prevents the ingot from being stopped in time due to untimely control and thus collides and damages the electrical slip ring 40, thereby protecting the electrical slip ring 40 and ensuring the reliability of the equipment.

[0050] The baffle mechanism 50 is located at the inner end of the blank feeding roller 22. Preferably, the baffle mechanism 50 is fixed to the rotating disk 21 and rotates with the rotating disk 21.

[0051] Furthermore, the electrical slip ring 40 is located at the center of the rotating mechanism 20, a plurality of baffle mechanisms 50 are distributed around the electrical slip ring 40, and the slewing support mechanism 10 is located at the center of the rotating mechanism 20. The baffle mechanisms 50 distributed around the electrical slip ring 40 can respectively block the ingots at various positions on the rotating mechanism 20 to provide all-round protection for the electrical slip ring 40.

[0052] Furthermore, if Figure 5 and Figure 6As shown, the baffle mechanism 50 includes a support seat 51, a movable baffle 52 and a buffer 53, wherein the movable baffle 52 is connected to the support seat 51 through the buffer 53. When the billet hits the movable baffle 52, the movable baffle 52 moves inward, and the buffer 53 applies resistance to the movable baffle 52, thereby preventing the movable baffle 52 and the billet from continuing to move inward. The buffer 53 can be an elastic member such as a spring.

[0053] Furthermore, the support seat 51 is provided with a guide cylinder 511, and the movable baffle 52 is connected to a sliding cylinder 521. The sliding cylinder 521 can be movably arranged in the guide cylinder 511, and the sliding cylinder 521 can move relative to the guide cylinder 511 along the longitudinal direction of the guide cylinder 511. During the inward movement of the movable baffle 52, relative movement occurs between the sliding cylinder 521 and the guide cylinder 511, and a guiding effect is played on the sliding cylinder 521 and the movable baffle 52, so that the movement of the movable baffle 52 is more stable, which is beneficial for the buffer member 53 to buffer the movement of the movable baffle 52, so that the ingot can be stopped smoothly to avoid impact on the electrical slip ring 40.

[0054] The electrical slip ring 40 mainly involves the contact and cooperation between the conductive ring and the brush block, and realizes the transmission of electric energy and signals between the rotating part and the fixed part. The electrical slip ring 40 can adopt existing equipment on the market.

[0055] The rotating roller cannot rotate 360 ​​degrees. After the billet enters from the billet feeding direction, it rotates 90 degrees counterclockwise and comes out from the billet discharging direction. After the billet is out, the rotating roller needs to rotate 90 degrees clockwise and return to the billet feeding position before the billet can be fed again.

[0056] The rotating roller for casting the billet provided by the utility model can rotate 360 ​​degrees. After the billet enters a billet feeding roller 22 from the billet feeding direction, it rotates 90 degrees to the billet discharging direction. After the billet is discharged, the rotating roller does not need to rotate, and the next billet can enter the next billet feeding roller 22, and then continue to rotate.

[0057] The rotating roller for casting billets provided by the utility model can be arranged in a cross-shaped manner, can be used as a rotating roller for square and round billets, and can be used in a multi-stream square and round billet continuous casting machine 71 in a steel plant, and has the following characteristics: 1) each time the billet is delivered, it only needs to rotate 90 degrees, which improves the billet delivery efficiency; 2) a baffle mechanism 50 is provided at the end of the billet delivery roller 22, which increases the safety of the equipment; 3) it can rotate 360 ​​degrees clockwise and counterclockwise, which increases the various possibilities of billet delivery; 4) the equipment is reliable, simple in structure, high in precision, wide in scope of use, and easy to maintain.
