Description

Technical Field

[0001] This invention relates to the field of metallurgical machinery, and more particularly to a traverse trolley for a slope-climbing slab continuous casting machine. Background Technology

[0002] At present, there is a height difference between the billet discharge roll surface and the hot delivery roll surface in most steel plants. If a billet lifting device is designed in accordance with the conventional method, it will result in a large equipment weight, high investment cost, and slow billet discharge rhythm of the twin-strand slab continuous casting machine. Therefore, it is necessary to develop a ramp-type slab continuous casting machine transverse trolley without affecting the billet discharge efficiency. Summary of the Invention

[0003] To address the problems of large equipment weight, high investment cost, and slow billet output in current twin-strand slab continuous casting machines, this invention provides a ramp-type traverse trolley for slab continuous casting machines.

[0004] To achieve the purpose of this invention, a traverse trolley for a slab continuous casting machine with an incline is provided, comprising: a frame, a track, a roller assembly, an anti-slip component, and a moving component;

[0005] Multiple roller assemblies are installed on the frame. The roller assemblies are arranged evenly along the length of the frame, and the multiple roller assemblies gradually increase in height along the billet discharge direction.

[0006] Anti-slip components are provided on one end of the frame away from the direction of billet output;

[0007] The anti-slip assembly includes a mounting bracket, push claw, pin, baffle, first bushing and second bushing. The mounting bracket is installed on the top of the vehicle frame. There are two baffles installed on both sides of the top of the mounting bracket. The baffles are inserted through the two pins. Push claws are rotatably connected to the pins. A first bushing is provided between the baffle and the pin, and a second bushing is provided between the push claw and the pin.

[0008] The moving component is installed at the bottom of the frame and can reciprocate along the track along the width of the frame.

[0009] In some specific embodiments, the anti-slip component further includes:

[0010] The hydraulic cylinder is mounted on one side of the pin.

[0011] In some specific embodiments, a single roller assembly includes a bearing housing, a roller, and a drive motor;

[0012] There are two bearing housings, which are installed on opposite sides of the frame in the width direction. The roller is installed on the bearing housings. The drive motor is located on one side of the bearing housing and is used to drive the roller.

[0013] In some specific embodiments, multiple lubrication pipes are also connected to the frame for lubricating the bearing housings.

[0014] In some specific embodiments, the moving component includes a bracket, an axial drive wheel assembly, and an axial driven wheel assembly;

[0015] The bracket is installed at the bottom of the frame, and the driven wheel assembly and the driven wheel assembly are respectively located on both sides of the bracket.

[0016] In some specific embodiments, hydraulic buffers are provided on opposite sides of the support body along its length.

[0017] In some specific embodiments, the angle between the roller and the adjacent higher roller is 1.15663 degrees.

[0018] In some specific embodiments, the flatness of each roller is less than or equal to 0.15 mm.

[0019] In some specific embodiments, guide frames are provided on both sides of the support between two adjacent roller assemblies, and the guide frames gradually increase in height along the billet discharge direction.

[0020] In some specific embodiments, the bearing housing is covered with a protective cover.

[0021] The beneficial effects of this invention are:

[0022] The inclined slab continuous casting machine transverse trolley provided by this invention assembles multiple rollers that gradually increase in height along the billet discharge direction, allowing the billet to be gradually lifted as it moves on the rollers. Therefore, this invention perfectly solves the problem of the height difference between the billet discharge roller surface and the hot delivery roller surface without affecting the billet yield, avoiding the problems of increased equipment weight, high operating costs, and slow billet discharge pace that occur when adding lifting devices. Moreover, this invention has a simple structure, requiring only simple modifications to existing transverse trolleys, reducing equipment investment costs and significantly shortening the time required for equipment upgrades, preventing prolonged downtime that could impact company profits.

[0023] This invention also includes multiple anti-slip components on one end of the frame away from the billet discharge direction. Each anti-slip component includes a mounting bracket on a support frame, with two baffles fixedly connected to both sides of the mounting bracket. A pin passes through the two baffles, and a pusher claw is rotatably connected to the pin. The pusher claw is irregularly shaped and aligned with the direction of the billet. Therefore, the anti-slip device prevents the billet from falling. If the billet slides backward along the casting flow while traveling on the rollers of the transverse trolley, the pusher claw will stop it. Simultaneously, the pusher claw will rotate due to the force of the billet, allowing for flexible contact between the pusher claw and the billet, preventing direct contact and damage. Thus, this device can stably, effectively, quickly, and continuously provide the required billets for hot conveying. Attached Figure Description

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A traverse trolley for a slab continuous casting machine with an incline mechanism includes: a frame 110, roller assemblies 120, a moving component 130, and an anti-slip component 140. Multiple roller assemblies 120 are mounted on the frame 110 and are evenly arranged sequentially along the length of the frame 110. The roller assemblies 120 gradually increase in height along the billet discharge direction.

[0036] Specifically, in this embodiment, there are seven roller assemblies 120 arranged from low to high as follows: roller assembly 120, roller assembly 2, roller assembly 120, roller assembly 3, roller assembly 4, roller assembly 120, roller assembly 5, roller assembly 120, and roller assembly 7. Seven mounting platforms 150 are fixedly connected to the top surface of the frame 110. The seven mounting platforms 150 are evenly arranged along the length of the frame 110 and gradually rise along the billet discharge direction. The seven roller assemblies 120 are respectively mounted on the seven mounting platforms 150 and rise as the mounting platforms 150 gradually rise. The elevation increase from roller #1 to roller #7 is approximately 206mm (the height of roller #7 minus the height of roller #1 equals 206mm). If this height is insufficient to meet the height difference between the billet discharge roller surface and the hot conveying roller surface, other equipment sections can be raised and combined with the raised design of this section to meet the height difference. This device is flexible and adaptable, perfectly solving the problem of the height difference between the billet discharge roller surface and the hot conveying roller surface, avoiding the problems of heavy equipment, high operating costs, and slow billet discharge pace caused by adding lifting devices. Moreover, the structure of this invention is simple, requiring only a simple modification to the mounting platform 150 on the top surface of the frame 110 in the existing technology. This reduces equipment investment costs and significantly shortens the time required for equipment upgrades, preventing prolonged downtime that could affect company profits.

[0037] In some specific embodiments of the present invention, an anti-slip component 140 is provided on one end of the frame 110 away from the blanking direction.

[0038] Specifically, four sets of anti-slip components 140 are installed on the left side of the No. 1 roller assembly 120. Each anti-slip component 140 includes a mounting bracket 141, pushers 142, pins 143, baffles 144, a first bushing 145, and a second bushing 146. The mounting bracket 141 is installed on the top of the frame 110. Two baffles 144 are installed on either side of the top of the mounting bracket 141 to prevent the pushers 142 from falling off during movement. The pins 143 pass through the two baffles 144. There are two pushers 142, both irregularly shaped plates, rotatably connected to the pins 143. The two pushers are installed at different angles, creating an opening aligned with the direction of the casting billet. During the movement of the casting billet on the rollers 122 of the transverse trolley, due to the height of the roller assembly 120, the casting billet may slip backwards along the casting flow. If this occurs, the pusher 142 will press against the billet, and simultaneously rotate due to the force of the billet, allowing for flexible contact between the pusher 142 and the billet, preventing the billet from directly contacting the obstruction and causing damage. While restricting the movement of the billet, the roller assembly 120 will continue to operate, moving the billet towards the exit direction, while the pusher 142 returns to its original position. Therefore, this device not only prevents the billet from falling off but also provides a stable, efficient, high-speed, and long-term supply of the required billets for hot conveying.

[0039] A first bushing 145 is provided between the billet baffle 144 and the pin 143, and a second bushing 146 is provided between the pusher 142 and the pin 143, so that the pusher 142 can rotate more smoothly. A hydraulic cylinder 147 is also provided on one side of the pin 143 to keep the pin 143 and the first bushing 145 and the second bushing 146 lubricated, so as to prevent the pusher 142 from getting stuck and causing damage to the billet.

[0040] In some specific embodiments of the present invention, the movable component 130 is installed at the bottom of the frame 110, and the movable component 130 can reciprocate along the width direction of the frame 110 on the track 160.

[0041] Specifically, the moving component 130 includes a bracket 131, an axial drive wheel assembly 132, and an axial driven wheel assembly 133. Two tracks 160 are laid along the width of the frame 110. The bracket 131 is installed at the bottom of the frame 110, and the axial drive wheel assembly and axial driven wheel assembly are respectively located on both sides of the bottom of the bracket 131. The axial drive wheel assembly includes two first wheels, an axle, and a motor, and is installed at the bottom of the bracket 131. The motor drives the first wheels. The axial driven wheel assembly includes two second wheels and is installed at the bottom of the bracket 131. The axial drive wheel assembly drives the axial driven wheel assembly to move on the track 160 and transports the cast billet on the roller assembly 120 to the hot conveying roller conveyor. The wheel spacing tolerance between the first and second wheels is ±0.5mm. The centerlines of the four wheels are coaxial and parallel, with a coaxiality tolerance of ±0.1mm and a parallelism tolerance of ±0.2mm. The wheels must rotate flexibly without abnormal noise or jamming to ensure the normal operation of the device.

[0042] In some specific embodiments of the present invention, such as Figure 3 As shown, two hydraulic buffers 190 are installed on the left and right sides of the bracket 131 respectively. The hydraulic buffers 190 on both sides can cooperate with the lower object to stop the moving traverse trolley, avoid excessive movement of the traverse trolley, prevent accidents, and avoid unnecessary losses.

[0043] In some specific embodiments of the present invention, a single roller assembly 120 includes a bearing housing 121, a roller 122, and a drive motor 123;

[0044] Two bearing housings 121 are installed on opposite sides of the frame 110 in the width direction. Rollers 122 are installed on the bearing housings 121. A drive motor 123 is located on one side of the bearing housing 121 and is used to drive the rollers 122. The angle between roller 122 and the adjacent higher roller 122 is 1.15663 degrees. The surface elevation of each roller should be on the same plane, with a flatness of less than or equal to 0.15 mm, and the perpendicularity of the centerline of each roller to the longitudinal centerline of the frame 110 should be less than or equal to 0.15 mm.

[0045] In some specific embodiments of the present invention, a plurality of lubrication pipes 170 are also connected to the frame 110. The lubrication pipes 170 are connected to the bearing seat 121 and are used to lubricate the bearing seat 121 to prevent the roller 122 from jamming and affecting the operation of the device.

[0046] In some specific embodiments of the present invention, guide frames 180 are provided on both sides of the support 131 between two adjacent rollers 122. The guide frames 180 gradually increase in height along the billet discharge direction to prevent the billet from falling off both sides of the long direction of the frame 110.

[0047] In some specific embodiments of the present invention, a protective cover 210 is provided on the bearing housing 121 to protect the bearing housing 121 and increase the service life of the device.

[0048] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "a specific embodiment" or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of terms do not necessarily refer to the same embodiment or example.
