Description

Technical Field

[0001] This utility model relates to the field of steel smelting technology, specifically to a connecting assembly structure suitable for fastening a sliding plate. Background Technology

[0002] In the sintering production line of the ironmaking plant, the sintering machine consists of a closed track laid on a steel structure and a series of sintering trolleys that move continuously on the track. Multiple sintering trolleys are connected in sequence to form a ring. A sealing device is installed at the bottom of the sintering trolley, and a sliding plate is arranged below the sealing device. During the production process, the sealing device of the sintering trolley comes into contact with the sliding plate surface and plays a sealing role through sliding friction.

[0003] The slide plate is a crucial piece of equipment in sintering production. If it becomes loose during production, it must be addressed immediately. Failure to do so will cause the sealing device of the sintering trolley to pry up the slide plate, potentially lifting the entire slide plate on that side, leading to severe air leakage and a major production failure.

[0004] In existing technology, the sliding plate is generally fixed by using a round countersunk hole 11 and a round internal hex bolt for fastening, such as... Figure 7 , Figure 8 , Figure 9 As shown, when a loose slide is found during production, tightening the nut under the slide is often impossible due to the rotation of the round hexagonal bolt. Generally, it is necessary to first arrange personnel to monitor the process, stop the material feeding, and empty 1 to 3 production trolleys. After the empty trolleys move to the loose slide, the machine is stopped and the power is cut off. The empty trolleys (it is difficult to lift a fully loaded trolley) are then lifted, the slide is tightened, and production resumes after the trolleys are restored. The whole process is cumbersome, requires dedicated personnel for command and coordination, and takes a long time to repair, which greatly affects production. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a connecting assembly structure suitable for fastening skateboards.

[0006] According to the present invention, a connecting assembly structure for fastening a skateboard is provided, including a skateboard and a connecting component;

[0007] The skateboard is provided with one or more countersunk holes for connectors;

[0008] The connector includes a connecting rod, an anti-rotation head, and a fastener. When the skateboard is fixed, the connecting rod passes through the countersunk hole of the connector. The upper end of the connecting rod is connected to the anti-rotation head, and the anti-rotation head is located inside the countersunk hole of the connector and is not allowed to rotate in the countersunk hole of the connector. The fastener is detachably arranged at the lower end of the connecting rod so as to fix the skateboard.

[0009] The torque on the connecting rod generated when the fastener is assembled is offset by the reaction force generated by the anti-rotation head in the countersunk hole of the connector.

[0010] Preferably, the anti-rotation head is rectangular in top view, and the countersunk hole of the connector is a rectangular hole that matches the anti-rotation head.

[0011] Preferably, the anti-rotation head is square in top view, and the countersunk hole of the connector is a square hole that matches the anti-rotation head.

[0012] Preferably, the anti-rotation head has an oblong hole shape when viewed from above, and the countersunk hole of the connector is an oblong hole that matches the anti-rotation head.

[0013] Preferably, a spring washer is provided between the fastener and the slide plate.

[0014] Preferably, the connecting rod and the anti-rotation head are an integral structure.

[0015] Preferably, the slide plate is provided with an even number of countersunk holes for connectors.

[0016] Preferably, the skateboard has two countersunk holes for connectors.

[0017] Preferably, the top surface of the skateboard is the skateboard surface;

[0018] The top end face of the anti-rotation head is lower than the surface of the sliding plate.

[0019] Preferably, the connecting rod connecting to the anti-rotation head is a T-shaped screw, and the fastener is a nut.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention, through the matching design of the anti-rotation head and the countersunk hole of the connector, allows the slide plate to be tightened simply by stopping the machine and re-tightening the fasteners when it becomes loose during production. This eliminates the need for empty trolleys, hoisting trolleys, and restoring trolleys, significantly reducing maintenance time. Furthermore, the structure is simple, easy to install, and highly portable, requiring no special tools or auxiliary equipment, making it suitable for various sintering machine slide plate loosening scenarios under different working conditions.

[0040] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0041] Example 1:

[0042] To address the problem of heavy maintenance tasks and long maintenance times caused by the need to hoist the production trolley when the bottom slide plate 1 becomes loose during the operation of the sintering machine trolley, this embodiment provides a connector assembly structure suitable for fastening the slide plate, including a slide plate 1 and a connector 2. The slide plate 1 is provided with one or more connector countersunk holes 12, preferably an even number of connector countersunk holes 12, for example, two connector countersunk holes 12 are provided on the slide plate 1.

[0043] Specifically, the connector 2 includes a connecting rod 21, an anti-rotation head 22, and a fastener 23. When it is necessary to fix the slide plate 1, the connecting rod 21 passes through the countersunk hole 12 of the connector. The upper end of the connecting rod 21 is connected to the anti-rotation head 22, and the anti-rotation head 22 is located inside the countersunk hole 12 of the connector, and the anti-rotation head 22 is not allowed to rotate in the countersunk hole 12 of the connector. The fastener 23 is detachably arranged at the lower end of the connecting rod 21 so as to fix the slide plate 1.

[0044] Specifically, the torque on the connecting rod 21 generated when the fastener 23 is assembled is offset by the reaction force generated by the anti-rotation head 22 in the countersunk hole 12 of the connector. Therefore, the connector 2 can be assembled and the slide plate 1 can be fixed by simply operating the fastener 23 from the space below the slide plate 1. There is no need to lift the production trolley, which simplifies the maintenance task, reduces maintenance costs, and greatly shortens maintenance time.

[0045] To increase the stability of the slide plate 1 after fastening, a spring washer is provided between the fastener 23 and the slide plate 1. This can provide a certain buffer against vibrations and radial torque generated during the operation of the production trolley, and can prevent the slide plate 1 from loosening to a certain extent.

[0046] Specifically, the anti-rotation head 22 can be a rectangular, square, or oblong hole structure when viewed from above. The countersunk hole 12 of the connector is matched with the anti-rotation head 22 and is also a square, rectangular, or oblong hole structure. When the anti-rotation head 22 is installed in the countersunk hole 12 of the connector, it can prevent the anti-rotation head 22 from rotating. This allows the connector 2 to be assembled by operating the fastener 23 from below the slide plate 1 when assembling the fastener 23.

[0047] Specifically, the top surface of the slide plate 1 is the slide plate surface. To ensure the practicality of the top of the slide plate 1, the top end face of the anti-rotation head 22 is slightly lower than the slide plate surface, so that the sealing device at the bottom of the sintering trolley will not interfere with the slide plate surface due to the anti-rotation head 22.

[0048] In practical applications, the connecting rod 21 and the anti-rotation head 22 are preferably integrated into one structure, which can increase the overall strength and improve stability.

[0049] Example 2:

[0050] This embodiment is a preferred example of Embodiment 1. The connecting rod 21 and the anti-rotation head 22 are integrally formed T-shaped screws. The anti-rotation head 22 has a square structure when viewed from above. The fastener 23 is a nut. Figure 3 , Figure 4 As shown, when the T-screw is assembled into the countersunk hole 12 of the connector, the square anti-rotation head 22 is matched and assembled into the countersunk hole 12 of the connector. When the nut is screwed from the bottom of the slide plate 1, the T-screw cannot rotate. Therefore, the slide plate 1 can be fastened by screwing the nut from the bottom of the slide plate 1.

[0051] Example 3:

[0052] This embodiment is another preferred example of Embodiment 1. Unlike Embodiment 2, the anti-rotation head 22 is viewed from above as a rectangular structure, such as... Figure 5 As shown, when the T-shaped screw is assembled into the countersunk hole 12 of the connector, the rectangular anti-rotation head 22 is matched and assembled into the countersunk hole 12 of the connector, which can also achieve the effect of fastening the slide plate 1 by screwing the nut under the slide plate 1.

[0053] Example 4:

[0054] This embodiment is another preferred example of Embodiment 1. The difference from Embodiment 2 is that the anti-rotation head 22, viewed from above, has an oblong hole structure, as shown... Figure 1 , Figure 2 , Figure 6 As shown, when the T-shaped screw is assembled into the countersunk hole 12 of the connector, the waist-shaped anti-rotation head 22 is matched and assembled into the countersunk hole 12 of the connector, which can also achieve the effect of fastening the slide plate 1 by screwing the nut under the slide plate 1.
