Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery technology, specifically to a detachable billet-carrying trolley wheel box. Background Technology

[0002] In the production process of continuous casting machines, the billet trolley is the core equipment for material handling and transfer. Its operational stability and reliability are of immeasurable value for maintaining the efficient operation of the production line and ensuring product quality. The design of the billet trolley needs to take into account multiple aspects such as load-bearing capacity, smooth operation and ease of maintenance in order to cope with the complex and ever-changing industrial production environment.

[0003] Traditional blank-picking trolley wheel designs mostly rely on pin-type insertion connections. This structure performs well in the initial use, but over time, the pins are prone to wear under long-term heavy loads and frequent friction, which affects the stability and service life of the wheels. Once a wheel malfunctions, such as severe pin wear or bearing damage, the wheel needs to be replaced. However, due to the tight connection characteristics of the pin-type insertion, the disassembly and reinstallation process of the wheels becomes extremely cumbersome and time-consuming, seriously affecting the continuous operation capability of the production line.

[0004] In addition, different models of billet-picking trolleys often have different weights due to differences in their structure, purpose, and load-bearing capacity. When changing the wheels or performing other maintenance work, the trolley usually needs to be lifted. In order to ensure safety during the lifting process and prevent the trolley from being damaged due to accidental falls, a buffer pad needs to be installed at the bottom of the trolley. However, due to the weight difference of different models of trolleys, the required buffer pad has different buffering capacity. Therefore, each time the wheels are changed or other maintenance is performed, it is necessary to select the appropriate buffer pad for installation according to the specific model and weight of the trolley.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5This utility model provides a technical solution: a detachable wheel box for a billet-picking trolley, including a billet-picking trolley 1, a box 2 threadedly mounted on the bottom of the billet-picking trolley 1, a connecting plate 3 fixedly mounted on the bottom of the box 2, multiple rotating shafts 4 fixedly mounted on the inner wall of the connecting plate 3, and a wheel 5 rotatably mounted on the outer wall of each rotating shaft 4. Bolts 6 are threadedly mounted on the inner wall of the box 2, and the box 2 is connected to the bottom of the billet-picking trolley 1 by threads. This design makes the disassembly and installation of the box 2 very convenient. When the wheel 5 malfunctions, the operator does not need to perform complicated disassembly. To disassemble the work, simply loosen the bolts 6 to remove the entire box 2 for quick replacement or repair. There are ten bolts 6, each with a specification and size of M30×120. The M30×120 bolts 6 have a larger diameter and length, providing greater clamping force and shear resistance. The ten bolts 6 are evenly distributed on the inner wall of the box 2, ensuring a very firm connection between the box 2 and the bottom of the billet trolley 1, effectively resisting various forces and vibrations generated during operation, and preventing loosening or falling off.

[0028] Please see Figure 3 , Figure 4 The present invention provides a technical solution: a detachable blank-picking trolley wheel box, including a blank-picking trolley 1 with a clamping plate 15 attached to the bottom, and buffer mechanisms installed at both ends of the bottom of the clamping plate 15;

[0029] The buffer mechanism includes a hollow column 14 fixedly installed at the bottom of the clamping plate 15, a hollow connecting block 13 fixedly installed at the bottom of the hollow column 14, a screw 9 slidably installed on the inner wall of the hollow connecting block 13, a sliding ring 12 slidably installed on the outer wall of the screw 9, and a spring 11 fixedly connected to the bottom of the sliding ring 12. When the billet picking trolley 1 is subjected to impact or vibration, the spring 11 can absorb and disperse this energy, reducing damage to the trolley itself and the billet it carries. A nut 10 is rotatably installed at the bottom of the spring 11. The nut 10 is threadedly connected to the outer wall of the screw 9. By adjusting the position of the nut 10 on the screw 9, the preload of the spring 11 can be adjusted, thereby adapting to billet picking trolleys 1 of different weights.

[0030] Please see Figure 3 , Figure 4This utility model provides a technical solution: a detachable trolley wheel box, including a buffer mechanism with a buffer assembly rotatably mounted on the side wall. This assembly includes a connecting shaft 17 rotatably mounted on the side wall of a hollow connecting block 13. A slide rod 26 is fixed to the side end of the connecting shaft 17, and a fixed plate 23 is fixedly mounted on the top of the slide rod 26. The side wall of the fixed plate 23 is fixedly connected to a spring 24, and the other end of the spring 24 is connected to a sliding ring 25. A buffer column 18 is slidably mounted on the outer wall of the slide rod 26. The side end of the buffer column 18 is fixed to the connecting shaft 19 via a connecting rod 22. The connecting shaft 19 is rotatably mounted on a fixed block 21. When the trolley 1 is lifted and accidentally falls, the buffer mechanism itself can absorb and disperse energy, and the newly added buffer assembly can further absorb and disperse this energy. A rotating column 16 is rotatably mounted at the connection between the hollow connecting block 13 and the connecting shaft 17, and a rotating column 20 is rotatably mounted at the connection between the connecting shaft 19 and the fixed block 21.

[0031] Please see Figure 3 , Figure 5 This utility model provides a technical solution: a detachable blank-picking trolley wheel box, including a fixed block 21 with a pad 8 fixedly installed on the side wall, the bottom surface of the inner wall of the pad 8 being fixedly connected to the screw 9, and a buffer assembly being rotatably installed on both sides of the hollow connecting block 13, the side ends of the buffer assembly being fixedly connected to the inner side wall of the pad 8.

[0032] Please see Figure 5 This utility model provides a technical solution: a detachable blank-picking trolley wheel box, including a card plate 15 with a card slot 27 on the top, a card strip 7 being snapped into the inner wall of the card slot 27, and the top of the card strip 7 being fixedly connected to the bottom of the blank-picking trolley 1. The snapping method between the card strip 7 and the card slot 27 makes the installation and disassembly process simple and quick, and the workers can quickly install the card plate 15 into the bottom of the blank-picking trolley 1.

[0033] Working principle: 1. When it is necessary to replace the wheel 5, use a crane to lift the end beam of the billet trolley 1 and place a buffer mechanism between it and the track. Remove the 10 M30×120 bolts 6 of the box 2 on the upper part of the wheel 5. Use a crane to completely remove the box 2 with the wheel 5 installed. Then install the box 2 with the new wheel 5 in the same way.

[0034] 2. By adjusting the position of the nut 10 on the screw 9, the preload of the spring 11 can be adjusted to accommodate different weights of the billet-picking trolley 1. When the billet-picking trolley 1 falls accidentally during hoisting, the buffer mechanism and buffer assembly can work together to absorb and disperse energy, protecting the billet-picking trolley 1 from damage.
