Description

Technical Field

[0001] This utility model relates to the technical field of steel coil transportation equipment, specifically to a coil transportation system. Background Technology

[0002] Steel coil transport devices are one of the most commonly used and important pieces of equipment in strip steel production workshops. Depending on the application, steel coil transport devices can be cranes, walking beams, or steel coil transport trolleys. Currently, steel coil transport between two different production lines generally uses steel coil transport trolleys. Arranging these trolleys usually involves digging a pit in the transport direction. The steel coil transport trolleys travel in the pit, making it impossible for vehicles or people to drive or walk above, affecting the plant's logistics layout and space utilization. It also poses a risk of personnel and goods falling, impacting the safety of personnel and equipment. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 and Figure 2 This utility model provides a steel coil transportation system, including a coil transport vehicle 1, an electrified track and a grounded track 3. The electrified track and the grounded track 3 are arranged parallel to each other on the workshop floor. The bottom of the coil transport vehicle 1 is provided with a set of traveling wheels, a traveling drive mechanism and a grounded wheel 16. The traveling wheels travel on the electrified track and the grounded wheel 16 travels on the grounded track 3. The traveling drive mechanism includes a drive unit 14 that drives and cooperates with the traveling wheels and a power extraction unit for drawing power from the electrified track. The power extraction unit is electrically connected to the drive unit 14.

[0022] The aforementioned electrified rails are low-voltage rails and will not cause personal injury to on-site personnel.

[0023] Among them, such as Figure 1 and Figure 2 The aforementioned electrified track includes two traveling rails 2, each of which is equipped with a traveling wheel 13. The two traveling rails 2 and the grounding track 3 are parallel to each other; furthermore, as Figure 1 Each track 2 can be equipped with multiple wheels 13, which can distribute the load and improve the load-bearing capacity and running stability of the coil transport car 1.

[0024] In one embodiment, such as Figure 1 and Figure 2 The grounding track 3 is arranged between the two traveling wheel rails 2. On the one hand, the grounding track 3 can be arranged in the space between the two traveling wheel rails 2, which can save the arrangement space; on the other hand, the grounding wheel 16 can support the coil transport car 1 in the middle, so this layout helps to maintain the balance and stability of the coil transport car 1.

[0025] In one embodiment, such as Figure 2In the traveling wheel assembly, some wheels are driving wheels 131, and the rest are driven wheels 132. The driving wheels 131 are connected to the drive unit 14. Furthermore, each driving wheel 131 travels on the same traveling wheel rail 2, which is defined as the driving wheel 131 rail; each driven wheel 132 travels on the same traveling wheel rail 2, which is defined as the driven wheel 132 rail. This rail-based drive method helps optimize power distribution. For example, when the drive unit 14 draws power from the electrified rail, only the driving wheel 131 rail can be electrified, while the driven wheel 132 rail can be de-energized, saving energy and further improving on-site operational safety. Accordingly, at least the driving wheel 131 rail is designed to be electrified, and the power-drawing unit is connected to the electrified rail in a sliding power-drawing manner.

[0026] The aforementioned power-taking unit includes, but is not limited to, methods such as setting brushes on the drive wheel 131, with the brushes moving with the drive wheel 131 to achieve a sliding power-taking connection with the electrified rail.

[0027] As described above, at least one of the travel rails 2 is an electrified rail. Furthermore, the travel wheel 13 traveling on the electrified rail is designed as an insulated wheel. This design effectively prevents current from forming an unnecessary circuit or causing a short circuit through the wheel and the frame 11, and prevents the vehicle body from becoming electrified and causing safety problems.

[0028] In one embodiment, such as Figure 3 The insulated wheel body 130 and axle 133 are connected by an insulated transmission key 134 to achieve power transmission while maintaining electrical insulation. An insulating sleeve 135 is also fitted onto the axle 133, and the insulating sleeve 135 is tightly fitted into the inner axle hole of the wheel body 130, further ensuring the insulation effect between the wheel body 130 and the axle 133. This structure achieves radial insulation of the wheel.

[0029] In one embodiment, such as Figure 3 An insulating pad 136 is provided between the wheel body 130 and an axially adjacent positioning structure (such as a bushing, end cap, etc.). The insulating pad 136 can be installed on the wheel body 130 and have a clearance fit with the adjacent positioning structure, or it can be installed on the positioning structure and have a clearance fit with the adjacent wheel body 130. The above structure achieves an insulation effect in the axial direction of the wheel axle 133.

[0030] The aforementioned insulated transmission key 134, insulating sleeve 135, and insulating pad 136 can be made of insulating materials such as nylon.

[0031] Regarding the structure of the coil transport vehicle 1, preferably, as follows: Figure 1 and Figure 2The coil transport vehicle 1 may include two independent frames 11 and a portal beam 12 connecting the two frames 11. The two frames 11 are movably mounted on two travel rails 2 via travel wheels 13. Each of the two frames 11 is equipped with a saddle 15, and the two saddles 15 are combined to form a saddle for carrying the steel coil 4. Connecting the two frames 11 into one unit via the portal beam 12 can effectively improve the structural stability and reliability of the coil transport vehicle 1, ensure the safety and reliability of transporting the steel coil 4, and enhance the vehicle's adaptability to steel coils 4 of different specifications.

[0032] Preferably, such as Figure 1 and Figure 2 The grounding wheel 16 is set on the saddle 15 on the corresponding side. This method not only facilitates the setting of the grounding wheel 16 and improves the compactness of the structural layout, but also allows the load on the saddle to be transferred to the grounding rail 3 through the grounding wheel 16. Therefore, it can greatly improve the load-bearing capacity of the saddle and ensure the safety and reliability of the transportation of the steel coil 4.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
